Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a mistake-proof tooling welding fixture. Background Technology

[0002] The factory also has some parts that require manual feeding and welding. When using the existing tooling welding fixtures, the workers are prone to misplacing the workpieces during operation. The position of the workpieces to be welded cannot be checked, and the placement error cannot be prevented. On the one hand, misplacing the workpieces will cause the welding points to deviate from the design position, thus affecting the accuracy and consistency of the welding. On the other hand, welding with incorrect position may cause the structural strength of the workpiece to fail to meet the design requirements, resulting in quality problems or safety hazards in the final product during use.

[0003] To address the above issues, we have developed a fault-proof welding fixture. Utility Model Content

[0004] This utility model discloses a fault-prevention tooling welding fixture, which aims to solve the technical problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fault-proof welding fixture includes a base plate, a support frame fixedly connected to the top of the base plate, a fixture body rotatably connected to the top of the support frame, a clamping groove on the top of the fixture body, a clamping plate slidably connected inside the clamping groove, a threaded rod threadedly connected to one side of the fixture body, one end of the threaded rod extending into the clamping groove and rotatably connected to one side of the clamping plate, a handwheel fixedly connected to the end of the threaded rod away from the clamping plate, detection sensors fixedly connected to both the side of the clamping plate away from the threaded rod and the inner wall of the clamping groove, a first gear fixedly connected to the outside of the central shaft of the fixture body, a first motor fixedly connected to the bottom of the support frame, the output shaft of the first motor passing through the support frame and fixedly connected to a second gear, the second gear meshing with the first gear.

[0007] The base plate and support frame provide stable support for the entire welding fixture. The rotating connection of the fixture body allows for flexible adjustment of the welding angle to adapt to different welding needs. The combination of the clamping slot and clamping plate, along with the threaded rod and handwheel, enables precise clamping and positioning of the workpiece. The design of the detection sensor detects the position of the workpiece in real time during clamping, ensuring correct installation and preventing welding errors. The meshing connection of the first and second gears, through the first motor, enables automatic rotation of the fixture body, improving the automation and accuracy of the welding process. It is suitable for occasions requiring precise clamping and multi-angle welding.

The third motor drives the horizontal movement of the connecting plate through the second lead screw, realizing the precise adjustment of the laser welding gun in the horizontal direction. This allows the laser welding gun to adapt to welding requirements of different lengths and positions, improving the welding range and accuracy. It is especially suitable for tasks that require flexible adjustment of the welding position.

[0012] In a preferred embodiment, a first limiting rod is fixedly connected to one side of the clamping plate and to both sides of the threaded rod, and the first limiting rod is slidably connected to the tooling body.

[0018] In a preferred embodiment, a control console is fixedly connected to the top of the base plate, and the detection sensor, the first motor, the second motor, and the third motor are all electrically connected to the control console.

[0019] By setting up a control console to centrally manage the control of the detection sensors and various motors, the welding process is automated and intelligent. The detection sensors detect the position of the workpiece in real time and transmit the data to the control console. The first motor, the second motor, and the third motor precisely adjust the position of the tooling body and the laser welding gun according to the instructions of the control console.

[0020] The error-proof welding fixture provided by this utility model has the following advantages:

[0021] In this invention, the precise clamping and positioning of the workpiece is achieved through a threaded rod and a handwheel. The design of the detection sensor detects the position of the workpiece in real time during the clamping process, ensuring the correct installation of the workpiece and preventing welding errors. On the one hand, position detection ensures that the workpiece is placed accurately before welding, and the welding points can be precisely aligned, thereby improving the consistency and reliability of welding.
