Abstract

The invention relates to a manufacturing process for a welding assembly line clamp bottom plate of an automobile production line. The manufacturing process comprises the following steps: blanking and reserving machining allowance; respectively blanking a frame square pipe, an upper clamp mounting plate, an end guide roller and an adjusting pin mounting plate, a middle guide roller and an adjusting pin mounting plate, and a middle adjusting pin mounting pin according to mounting drawings, and reserving the machining allowance on a mounting surface; chamfering the mounting surface; assembling and welding: enabling the planeness after welding to be within 2 mm, annealing, destressing, performing sand blasting, shot blasting and derusting, and grinding welding slag; performing rough machining: reserving the allowance of 1 mm on the mounting surface of the clamping mounting plate; performing fine machining: performing fine machining on the mounting surface, and machining a positioning hole and a screw hole; detecting; deburring. The manufacturing process provided by the invention is clear in step and explicit in requirements; the machining precision of a product can be effectively ensured; meanwhile, the machining efficiency of the product is improved; therefore, the manufacturing process is a scientific and reasonable machining process.

Description

technical field [0001] The invention belongs to the field of welding and assembly of automobile production lines, and in particular relates to a manufacturing process of a bottom plate of a welding and assembly line of an automobile production line. Background technique [0002] As the basic component of the welding fixture, the base plate of the welding line of the automobile production line supports and fixes the fixture, providing a base for the precise installation of the fixture and making it a whole. Its accuracy directly affects the accuracy of the positioning mechanism, so the fixture base plate The precise manufacturing is the foundation for the normal use of the whole set of fixtures. The bottom plate of the fixture is composed of a plate connected to the adjusting foot (or sliding table), a supporting frame of the bottom plate, and a plate connected to the upper fixture. Products that do not pass finishing cannot meet the requirements of use accuracy, and the use ...
