【文章內(nèi)容簡介】 premise of the structure of fixture should be as simple as possible. Fixture design is usually the general use of welded structures, the basic ponent is divided into three parts, namely base, support the positioning part, clamping parts, for each specific fixture positioning support base and some of the general use of 10 to 20 mm thick steel plate welded structure part of the normal 10 mm with a thickness of about 45 bination of welded steel plate. Pneumatic and manual clamping part of the two, according to the size of car production clamping method to determine the general highvolume pneumatic clamping, then manually clamping can be used as auxiliary clamping。 small quantities in order to reduce the cost of manually clamp mode. Manual clamping is usually manually fast clip, manual quick clip of their products has bee the standard, type and quantity needed can be purchased in the 6 market. For some fixtures require apneumatic clamping, but direct use of pneumatic clamping. May damage the workpiece, then, can be manually pressed first place, to give a pneumatic clamping force to clamp the workpiece, which is manual Pneumatic J the fixture clamping system is installed on a large platform, all guaranteed fixture in the welding position of welding conditions should be consistent with the design of the workpiece coordinate dimensions, which involves the positioning fixture benchmarks. 3 assembly and welding fixtures benchmarks and their choice of support surface t flipchip benchmark test fixture Each fixture must be a fixture coordinate system, in this coordinate system, the coordinates of its base of support size should be supporting the workpiece and the coordinates corresponding to the same size. Fixture coordinate system is established based on fixture side of the child base. Because the whole fixture system to guarantee a space auto welding pieces of threedimensional coordinate system, so this system in all of the fixture must have a mon benchmark, this benchmark is the fixture to install platform that is the X, Y Zuo Biao, each specific fixture in platform location, the corresponding height shall coordinate Z, so that threedimensional XYZcoordinate system is established. In order to facilitate the installation and measurement fixture, install the platform must have the coordinate
