Novel lower-bodywork repair welding, positioning and locking device

Abstract

The invention discloses a novel lower-bodywork repair welding, positioning and locking device and belongs to the field of welding fixtures. The novel lower-bodywork repair welding, positioning and locking device comprises a base, a support, a locking block, a pressing piece, a rocker arm, a rocker arm bracket, a cylinder guide rod, a cylinder mounting bracket and an air cylinder. The rocker arm is of a J structure like a sickle, and a part at the front end thereof is fixedly connected with the pressing piece. The rocker arm is hinged to the support through a connecting plate, the upper end of the connecting plate is fixedly connected with the rocker arm, and the lower end thereof is hinged to the support. An H-shaped buffer plate is arranged on the left side of the connecting plate. A tail end of the rocker arm is connected with the cylinder guide rod through the Y-shaped connecting rod, the upper end of the Y-shaped connecting rod is hinged to the rocker arm, and the lower end thereof is fixedly connected with the cylinder guide rod. The locking block is of a U structure, and one side of the locking block is provided with a position sensor. By the arrangement, welding precision is improved, and labor intensity of workers is greatly lowered. The novel lower-bodywork repair welding, positioning and locking device is reasonable in structural design, convenient and easy to operate, low in manufacturing cost and applicable to lower-bodyworks different in vehicle types.

Description

technical field [0001] The invention belongs to the field of welding tooling, and more specifically relates to a novel positioning and locking device for repair welding of a lower vehicle body. Background technique [0002] At present, most of the repair welding fixtures for the lower body of light vehicles are manually assembled and welded, which has poor adaptability and high labor intensity; or adopts large-scale automated welding equipment, which takes up a large area, requires a large investment in equipment, and requires relatively high operating requirements. High, such as single-row and double-row light trucks, bread light buses, and half-row light trucks, it is more difficult to weld mixed lines. Most of the existing welding fixtures can only be special fixtures, which can only adapt to one part or assembly. finished welding. Contents of the invention [0003] 1. Problems to be solved [0004] Aiming at the above-mentioned problems existing in the prior art, the...

AI Technical Summary

Problems solved by technology

[0002]Currently, most of the repair welding fixtures for the lower body of light vehicles are manually installed and welded, which has poor adaptability and high labor intensity; or large-scale automated welding equipment , Large-scale equipment occupies a large area, requires a large investment in equipment, and has high requirements for operation. For example, it is more difficult to weld mixed lines of four types of single-row and double-row light trucks, bread light buses, and half-row light trucks. The existing welding fixtures are large. Some parts can only be special fixtures, which can only be used for welding of one component or assembly
