Make in car automobile body in, normally need adds up to solder of assembly of a clamping apparatus that install solder, cent nearly 100 sets to install clamping apparatus and automobile body assembly to install solder clamping apparatus, car solder installs clamping apparatus and photograph of other clamping apparatus to compare, component of clamp of its fixed position face complex, precision asks production difficulty of tall, design is great. In the assembly of car automobile body solder deliver a child produces a course in, measure to make sure the product is simple, rise labor productivity and reduce labor intensity, the tool that often uses a few in order to to clip is held and fix work place and device will finish assemble and solder the job, these tools and unit be called by a joint name install clamping apparatus for solder. The sort of solder outfit clamping apparatus is various, can divide by utility for: Assemble used clamping apparatus, solder used clamping apparatus and outfit, solder clamping apparatus; Make in car automobile body in, assemble to facilitate and solder to also can divide for: Add up to solder of assembly of a clamping apparatus that install solder, cent to install clamping apparatus and automobile body assembly to install solder clamping apparatus. Car automobile body is made in normally need adds up to solder of assembly of a clamping apparatus that install solder, cent nearly 100 sets to install clamping apparatus and automobile body assembly to install solder clamping apparatus. Car solder installs clamping apparatus and photograph of other clamping apparatus to compare, component of clamp of its fixed position face complex, precision asks production difficulty of tall, design is great. Additional, because size of car spare parts is large, fixed position component cannot structure of make it whole, it is the fixed position that uses independence commonly board, installation is on integral motherboard. In clamping apparatus use process, if clamping apparatus locates component of component happening deflection, fixed position wears away to wait for a phenomenon not quite with pincers clamping force, will bring about spare parts twist to be out of shape, deviation of occurrence fixed position, cause solder of clearance fluctuant, bring about the aggravation that assembles on size error and component to accept power position finally, affect the precision of white automobile body directly. The automobile body of deviation origin car of precision of car automobile body is one of 3 much of the car, it is the carrier of whole car component. The actor bad of quality of outfit of automobile body solder is right truckload quality is having conclusive effect, solder installs dimension deviation to affect the quality of ultimate car product directly, wait like sex of sealed, noise, life, motivation and exterior. Error of automobile body dimension is main origin is as follows (if pursue 1) : Outfit of influence of clamping apparatus of the deviation of stamping workpiece itself, tool, solder is out of shape, operation influence. Among them stamping workpiece deviation and the mainest factor that welder installs clamping apparatus deviation is deviation of dimension of influence automobile body. The administrative welder of solder outfit clamping apparatus installs clamping apparatus to basically have the following side to the effect matter of automobile body precision: The invalidation of component of the designs unreasonable, clamping force influence of tool clamping apparatus, fixed position. The influence that commands each element also installs clamping apparatus to be affected to automobile body precision with respect to control welder, make sure automobile body assembles the accuracy of dimension. How to control clamping apparatus the influence of each element also is to be worth to consider and discuss a task, as a whole, it is the clamping apparatus of production high accuracy above all, it is precision of effective in the use process of clamping apparatus administrative clamping apparatus next. Clamping apparatus uses the government in the process, run policy: Fish different because, take step, try to eliminate, appear no longer, bring into a standard. Administrative method (if pursue 2) cent is day-to-day management and fixed management. Day-to-day management cent begins working inspection for clamping apparatus 5S and clamping apparatus. Fixed management cent is checked regularly for clamping apparatus and maintain, precision of fixed position component detects and automobile body precision detects. Precision of fixed position component detects divide again for appearance of fixed position component precision detects and precision of position of fixed position component detects. 5S of Nextpage1, clamping apparatus this not little entrepreneur thinks, the quality of production process manages, most fundamental job is " 5S " activity. Alleged " 5S " was to include the following the Japanese abbreviate of 5 respects content (the 3) that be like a graph: SEIRI (arrange) , SEITON (rectify) , SEISO (sweep) , SEIKETSU (clean) , SHITSUKE (accomplishment) . The enterprise pursues the action of 5S: Reduce waste, guaranty is qualitative, safeguard is safe, improve efficiency, strengthen employee attributive feeling, promote an enterprise image. Solder installs clamping apparatus 5S to basically manage a project is: Broken bits of clamping apparatus fixation, cleared solder, arrange messy tracheal etc, maintain clamping apparatus orderly and neat. 2, clamping apparatus begins the job to check clamping apparatus to begin the job to inspect an item basically is: The barometer, tracheal, air cylinder, switch that start, fixed position is sold, screw of fixed position piece, close solid and lubricant state normal, before clamping apparatus begins the work, check every time. Prevent an examination to omit, build clamping apparatus to begin list of working servy record. 3, clamping apparatus is checked regularly and maintain clamping apparatus is checked regularly and maintaining is to build clamping apparatus to begin the job to check a foundation over, basically be to be aimed at respect of clamping apparatus function to undertake check and maintaining, discovery is undesirable and seasonable repair, because accumulative total is undesirable,prevent and cause clamping apparatus great and undesirable, affect the precision of automobile body thereby. 4, precision of fixed position component detects the mainest in locating component is clamping apparatus comprise a component, it is deciding part be constructionaled the position in clamping apparatus, all spare partses that assured to be assembled thereby the technical requirement of mutual position, still solder certainly directly sometimes structural appearance. The precision of fixed position is affecting the precision of workpiece and crossing-over directly, affect the precision of automobile body. Because this assures the precision of fixed position component,have very important sense. In production process, the main management method of the precision that assures component of clamping apparatus fixed position is precision of appearance of fixed position component detects and precision of position of fixed position component detects. Precision of appearance of component of □ fixed position detects component of the fixed position in clamping apparatus use process can arise wear away, fixed position component has wearing away is inevitable, but the invalidation of fixed position component that locates the wear extent of component exceeds certain amount to be able to cause fixed position cell. So automobile body solder installs nearly 100 clamping apparatus to amount to 1700~2500 fixed position component, a provide according to producing actual condition time undertakes to locating component wears away cycle detects. Detect the method applies vernier calipers and micrometer to undertake metrical to fixed position component, use next measure numerical value actually to reduce numerical value of theory of fixed position component (the design is worth) , reach wear extent of fixed position component. Wear away real measured value of value = │ - theoretical value │ is caught calculative real wear extent and the biggest wear extent (set is a basis heat treatment of the material of fixed position component, surface and wear away the combinative production such as invalidation theory is actual) contrast, when: Real wear extent ≥ is the biggest wear extent, decide NG, change component of new fixed position; Real wear extent ＜ is the biggest wear extent, decide OK, continue to use. Precision of position of component of □ fixed position detects clamping apparatus is in use process, fixed position component besides wear away to still can produce deflection, the fixed position that locates because automobile body solder installs clamping apparatus design to use independence,the deflection of component is board. Deflection of fixed position component locates component position changes namely, the positional precision demand of component of fixed position of clamping apparatus of car solder outfit is very high, positional precision change is mixed with naked eye common measure a tool to detect hard, must appropriative of have the aid of 3 coordinate measuring instrument detects. Build clamping apparatus to locate component position precision manages record, combinative process capability analyses methodological analysis, according to analysing a report the fixed position component to invalidation undertakes adjustment. 5, automobile body precision detects in front the premise with told a when make sure solder outfit clamping apparatus is to assure automobile body precision fundamental, but in making a process actually, the cycle that measures nearly 100 solder to install clamping apparatus to locate component position precision needs is longer, and the use of clamping apparatus is very frequent, the positional invalidation of fixed position component may happen at any time, the error of automobile body precision that causes large quantities of amounts to prevent the be no longer in force that may happen is serious and sequential, solder uses converse management method in the management of outfit clamping apparatus, undertake online key place total number detects and leave a line fixed and truckload to detect to automobile body precision, according to the data analysis of detected automobile body precision, manage the precision of clamping apparatus conversely. Conclusion car makes industrial progress, the production precision of automobile body asks to had been not satisfied at the precision of ± 1mm, forward more high accuracy way develops, to solder precision of outfit clamping apparatus raised taller requirement, the active precision management in installing clamping apparatus to use a process to solder so also asks likewise taller. Pilot of precision of the clamping apparatus in production process of article introduction automobile body a few methods, expectation is passed through share experience together with everybody, the level that can raise Chinese automobile body to make.
