Welding fixture for automobile part machining

Abstract

The invention discloses a welding fixture for automobile part machining. The welding fixture for automobile part machining comprises a fixture bottom plate, a fixture body and a base, wherein the fixture body is fixed above the fixture bottom plate through a screw; the base is welded below the fixture bottom plate; the fixture body comprises a compression device, a transition block and a support seat; the support seat is L-shaped; the transition block is fixed to a side of the support seat through a plurality of location pins, and the compression device is arranged at the other side of the support seat; a location block is installed above a left side of the transition block through a location pin; an adjustment gasket is placed between the transition block and the location block, and a press block is arranged above the location block; a limit block is fixed to a left side of the transition block through a location pin; the limit block is as high as the location block; and an upper end of the location block faces the press block. The welding fixture for automobile part machining is high in location accuracy, and flexibility degree is remarkably increased; and the structures are relatively independent, simple in structure and convenient to replace, and production and machining costs are remarkably lowered.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a welding fixture used for auto parts processing. Background technique [0002] Automobile is the most important means of transportation in people's life. People's life is closely related to the development of the automobile industry. In the production of auto parts, welding fixtures for auto parts processing are indispensable, but the existing welding fixtures still have the following shortcomings: [0003] (1) The welding accuracy of welding fixture equipment directly determines the welding quality of auto parts. The positioning error of existing welding fixture equipment is relatively large, which is one of the important factors leading to welding error; [0004] (2) The welding fixture is a typical non-standard tooling, which has poor versatility and strong specificity, so the cost of automobile production is high; [0005] (3) The function of the welding jig ...
