Lifting welding support for automobile welding fixture with self-locking function

Abstract

The invention provides a lifting welding support for an automobile welding fixture with a self-locking function. The support is characterized by comprising a support platform, a mounting block, a lifting mechanism, a pushing mechanism and a locking mechanism, wherein the mounting block is mounted on the upper side of the support platform, the mounting block and the support platform are of an integrated structure, the pushing mechanism is arranged in the support platform and the mounting block, the locking mechanism is arranged on the upper side of the pushing mechanism, the lifting mechanism is arranged on the upper side of the support platform, and the lifting mechanism is arranged on the left side of the pushing mechanism. According to the support, the lifting mechanism is added, adjusting supports, lifting grooves and lifting sliding blocks are used to replace an existing X-shaped support, the stability is improved under the action of threads while a worm rotates, the phenomena that a welding workpiece falls to the ground due to vibration, and the welding workpiece is collided and damaged due to falling to the ground are further avoided, secondary manual machining is not needed any more, and a large number of manpower and material resources are reduced.

Description

technical field [0001] The invention relates to the technical field of welding brackets, in particular to a lifting welding bracket for automobile welding fixtures with a self-locking function. Background technique [0002] Welding, also known as welding and welding, is a manufacturing process and technology for joining metal or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. It is especially important in the automobile production process. With the development of production, the existing The fixture for automobile welding is equipped with an I-shaped structure transverse support block, an L-shaped structure longitudinal support block, a clamping arm and a clamping cylinder on its upper side, and the clamping arm is driven by the clamping cylinder to move, and then passed through the transverse direction of the I-shaped structure. The supporting block and the longitudinal supporting block of the L-shaped structure are use...

AI Technical Summary

Problems solved by technology

[0003] The automobile welding fixtures with self-locking function in the prior art are all fixed on the welding table on the top of the bracket by bolts. When the position of the welding workpiece needs to be changed, the cylinder connected to the bottom of the bracket is manually used to push the "X" shape. The bracket moves horizontally, and the top of the "X"-shaped bracket moves vertically through the horizontal movement of the bottom, which in turn drives the welding table to rise and fall. Although this can realize the longitudinal movement of the welding workpiece, with the continuous improvement of production technology, There are also great requirements for the precision of welding workpieces. When precise welding workpieces are required, since the cylinder is controlled by an air compressor, when pushing the "X"-shaped bracket to move horizontally, there is only one supporting point in the middle of the X-shaped bracket. , and the welding table has a certain weight, so that the displacement of the bottom of the "X"-shaped bracket is constantly changing, and the top is prone to shaking during the rising process, which makes the welding workpiece fall to the ground due to vibration, causing bumps and damage to the welding workpiece. Manual secondary processing adds a lot of manpower and material resources. Secondly, the welding bracket that is too shaken cannot accurately lift the welding workpiece during the rising process, resulting in welding errors and reducing the success rate of workpiece welding.
