Welding fixture for automobile steering system

Abstract

The invention discloses a welding fixture for an automobile steering system. The welding fixture sequentially comprises a bottom plate, two vertical plates, a turning disc and a mounting plate, wherein a positioning groove, a positioning plate, a rotating bracket, a through hole a and a rotatable rotating mechanism for fixing a workpiece are sequentially arranged on the central axis of the upper end surface of the mounting plate; air cylinders b, air cylinder mounting plates b, through holes c, press component brackets and round positioning pieces are sequentially and symmetrically arranged on the mounting plate on two sides of the rotating mechanism from far to near, push rods of the air cylinders b are inwards and horizontally arranged on the air cylinder mounting plates b, and press components are horizontally arranged on the press component brackets; air cylinders c are arranged on the back surface of the mounting plate where the through holes c are formed, and push rods of the air cylinders c are arranged in the through holes c. With the adoption of the welding fixture, assembly engineering can be reduced, poor engineering can be reduced, the production cost can be reduced, meanwhile, the human resource cost is reduced, and the product percent of pass is significantly increased; the welding precision is high, and the system error is small.

Description

technical field [0001] The invention relates to the field of welding jigs used in automobile manufacturing, in particular to an automobile steering system welding jig. Background technique [0002] In automobile manufacturing, it is necessary to use various auxiliary tools such as fixtures and jigs. In the manufacturing process, the steering system of an automobile requires more fixtures due to its complex structure. For example, two TA1400 welding robots are used to weld with three sets of welding fixtures. There are various combinations of 2 sets of TA1400 welding robots and 3 sets of fixtures. It is necessary to disassemble and install the next welding step after completing a working step. Such repeated installation and disassembly is a waste of time and manpower. , and the welding efficiency is low, and the repeated installation and disassembly also brings a problem, that is, due to the cumulative system error is getting larger and larger, the final product size is not...

There are various combinations of 2 sets of TA1400 welding robots and 3 sets of fixtures. It is necessary to disassemble and install the next welding step after completing a working step. Such repeated installation and disassembly is a waste of time and manpower. , and the welding efficiency is low, and the repeated installation and disassembly also brings a problem, that is, due to the cumulative effect of the system error is getting larger and larger, resulting in the final product size is not accurate enough, the pass rate is very low, and there is too much waste
