Fixture for sedan central pillar inner skin roof rail welding assembly

Abstract

The invention discloses a fixture for a sedan central pillar inner skin roof rail welding assembly. The fixture comprises a base, and a clamping device and an operating panel which are fixedly arranged on the base, wherein the top surface of the base is a horizontal mounting plane, and the bottom of the base is provided with casters; the clamping device comprises a bracket, a compaction rack and a driving device; the bracket is fixedly connected to the base; the compaction rack is hinged to the bracket; the driving device is used for driving the clamping and releasing of the bracket and the compaction rack; a positioning pin is arranged on the bracket; and a switch for controlling the work of the driving device is arranged on the operating panel. The fixture for the sedan central pillar inner skin roof rail welding assembly can control a corresponding driving device by the switch to drive a clamping positioning part to clamp and release a workpiece, improve the assembly and disassembly efficiency of the workpiece and reduce the labor intensity of an operator, and is convenient to move.

Description

technical field [0001] The invention relates to a fixture, in particular to a welding fixture used for welding the upper side beam welding assembly of the inner skin of the center pillar of a car. Background technique [0002] The welding fixture is a fixture used to ensure the size of the weldment, improve assembly accuracy and efficiency, and prevent welding deformation. [0003] The upper side beam welding assembly of the center pillar inner skin of the car is composed of the upper side beam of the center pillar, the inner skin of the center pillar and the lap joint plate of the roof beam. The support seat, pressure plate and fastening bolts corresponding to each component are composed. After each component is placed in the corresponding position, the corresponding pressure plate is pressed on the workpiece, and then the fastening screws used to connect the support seat and the pressure plate are manually tightened to realize the car. The components of the upper side bea...

Problems solved by technology

[0003] The center pillar inner skin upper side sill welding assembly is composed of the center pillar upper side sill, the center pillar inner skin and the ceiling cross beam lap plate welded together. The support seat, pressure plate and fastening bolts corresponding to each component are composed. After each component is placed in the corresponding position, the corresponding pressure plate is pressed on the workpiece, and then the fastening screws used to connect the support seat and the pressure plate are manually tightened to realize the car. The components of the upper side beam welding assembly of the center pillar inner skin are effectively positioned, and then welded and fixed at each weld seam in sequence, and finally the fastening bolts are removed manually, the pressure plate is removed, and the workpiece is removed to complete the welding. The beam welding assembly is composed of three parts welded, each part needs to be clamped and positioned separately, and a lot of pressure plates and fastening screws are required. The operation is time-consuming and laborious during the loading and unloading process of the workpiece, the processing efficiency is low, and the whole clamp body is thick and heavy , inconvenient to move
