Dual stud welding gun switching mechanism

Abstract

This invention provides a dual-stud welding torch switching mechanism, including a base, a main support mounted on the base, and an L-shaped support mounted on the main support. The corner of the L-shaped support is connected to the upper end of the main support via a rotating shaft. The L-shaped support rotates along the rotating shaft, and welding torches are mounted at both ends of the L-shaped support. Support frames are mounted on both sides of the upper end of the base, supporting the horizontal end of the L-shaped support. A tilting cylinder is mounted on the side of the main support, and the telescopic rod of the tilting cylinder is connected to the corner of the L-shaped support via a connecting hinge. The welding torches are mounted on the L-shaped support, and the tilting cylinder tilts the L-shaped support when needed, switching the welding torch position. This allows two welding torches to perform the work of three positions without occupying multiple sets of positions; the welding torch switching can be achieved in one position. It is suitable for processing on multi-model production lines, improving processing accuracy and providing good equipment stability.

Description

Technical Field

[0001] This invention relates to the field of multi-model production line technology, and in particular to a double stud welding torch switching mechanism. Background Technology

[0002] Currently, welding with welding torches is a common process in product manufacturing. Different welding torches are used to weld different parts of the product. Current welding methods involve setting up different welding stations and completing the welding work in steps, which occupies workspace, involves multiple processes, and increases processing time. While using multiple welding torches can solve these problems, multiple torches generally only complete welding in fixed positions and cannot be switched between torches. This prevents the processing of two different products on a single production line, requiring a complete line switchover. For example, published patent 2025228151504 discloses an automatic welding device for the end face of a spiral plate. This device uses an actuator to drive the welding torch to superimpose wavy and angular spiral welding trajectories on a reference spiral trajectory. Although it can change the position of the welding torch, it cannot switch the welding torch station. Therefore, solving the problem of current welding equipment's inability to switch welding torch stations is particularly important. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-stud welding torch switching mechanism. The welding torch is installed on an L-shaped bracket, and the L-shaped bracket is flipped when needed by a flip cylinder to switch the welding torch position. This allows two welding torches to complete the work of three positions without occupying multiple sets of positions. The welding torch can be changed at one position, which is suitable for processing on multi-model production lines and solves the problem that current welding equipment cannot complete the welding torch position switching.

[0004] This invention provides a dual-stud welding torch switching mechanism, including a base, a main support mounted on the base, an L-shaped support mounted on the main support, the corner of the L-shaped support connected to the upper end of the main support via a pivot, the L-shaped support rotating along the pivot, welding torches mounted at both ends of the L-shaped support, support frames mounted on both sides of the upper end of the base, the support frames mounted on both sides of the main support and supporting the horizontal end of the L-shaped support, a tilting cylinder mounted on the side of the main support, the telescopic rod of the tilting cylinder connected to the corner of the L-shaped support via a connecting hinge.

[0005] A further improvement is that the welding torch is mounted on an L-shaped bracket via a welding torch holder, and a position sensor is provided on the side of the welding torch holder to determine the position of the product to be welded.

[0006] A further improvement is that a buffer spring is provided on the support frame to provide buffer support for the L-shaped bracket, and a fastening clamp is also provided next to the support frame to clamp the L-shaped bracket on the support frame.

[0007] A further improvement is that: support platforms are provided on both sides of the main support, support blocks are provided on the support platforms, and pressure blocks corresponding to the support blocks are provided on the sides of the L-shaped support. Through the cooperation of the support blocks and pressure blocks, the support platforms provide auxiliary support for the L-shaped support.

[0008] A further improvement is that a limiting plate is provided on the welding torch holder to limit the minimum distance between products approaching the welding torch.

[0009] A further improvement is that the tilting cylinder is connected to the main support via a tilting shaft, and the tilting cylinder rotates along the tilting shaft.

[0010] The beneficial effects of this invention are as follows: The welding gun is installed on the L-shaped bracket, and the L-shaped bracket is flipped when needed by the tilting cylinder, which switches the welding gun's position. This allows two welding guns to complete the work of three positions without occupying multiple sets of positions. The welding gun can be changed at one position, making it suitable for processing on multiple production lines. At the same time, various sensors are set up to ensure the accuracy of the welding position of the welding gun, improving processing precision. In addition, the support platform provides auxiliary support for the L-shaped bracket, improving the stability of the equipment. Attached Figure Description
