Abstract

A sliding type vehicle body welding positioning pin working table comprises positioning pins, a driving mechanism and a movable working table, the driving mechanism is arranged on a fixed working table, the movable working table is arranged on the fixed working table in a sliding mode, a plurality of positioning pins are arranged on the movable working table, the movable working table is connected with the driving mechanism, and the driving mechanism drives the movable working table to act. The positioning pins are inserted into or withdrawn from the corresponding sheet metal part positioning holes; a movable block is arranged on the movable workbench, a limiting block is arranged at each of the two ends of the moving path of the movable block on the fixed workbench, the moving range of the movable block is located between the two limiting blocks, and a position inductive sensor is arranged beside each limiting block. And the position inductive sensor at the corresponding position sends out a signal to maintain the driving mechanism at the position, so that the positioning pin is maintained in a state of being inserted into the positioning hole of the sheet metal part or being far away from the position of the sheet metal part. According to the invention, synchronous telescoping of a plurality of positioning pins is realized.

Description

technical field [0001] The invention relates to the technical field of welding fixtures, in particular to a sliding-type vehicle body welding positioning pin workbench. Background technique [0002] During the welding process of the automobile body, it is necessary to use positioning pins to position the sheet metal parts of the body, so as to ensure the accuracy of welding. The positioning pin unit needs to be designed according to the structural characteristics of the sheet metal parts and welding needs, and installed in the welding fixture. Therefore, the welding fixture table is one of the essential tooling equipment on the welding production line. Considering the convenience of taking and placing the body sheet metal parts, the positioning pins placed in the vertical direction are generally fixed, but the positioning pins placed horizontally need to be driven by a cylinder to expand and contract. After the body sheet metal parts are placed in place, the positioning pins...
