Technical Field
[0001] This utility model relates to the field of mechanical metal processing technology, specifically an adjustable welding fixture for mechanical metal processing. Background Technology
[0002] Metalworking refers to the processing of metal materials using various mechanical equipment and tools to manufacture parts or products of required shapes and sizes. Metalworking is widely used in many industries, including automotive, aerospace, electronics, construction, and medical devices.
[0003] In the process of machining metals, adjustable welding fixtures are required to fix and position the workpiece to be welded, so as to ensure the accuracy and consistency of the welding process.
[0004] Existing adjustable welding fixtures for mechanical metal processing require a clamping plate that can move under the action of a hydraulic cylinder to achieve adjustable welding of the welding head. The movement of the clamping plate is used to clamp and fix the metal parts to be welded. However, due to the metallic nature of the metal parts to be welded, the clamping plate cannot guarantee the stability of the clamping and positioning of the metal parts to be welded, which affects the accuracy of the welding process. Utility Model Content
[0005] To address the above problems, the purpose of this utility model is to provide an adjustable welding fixture for mechanical metal processing, which solves the problem that the clamping plate cannot guarantee the stability of the clamping and positioning of the metal part to be welded due to its metallic nature, thus affecting the accuracy of the welding process. The pushing plate is resisted by the metal part to be welded and slides into the inner groove of the clamping plate through the sliding groove until the clamping plate clamps and positions the metal part to be welded. The anti-slip pad increases the friction between the pad and the metal part to be welded. At the same time, the clamping plate and the pushing plate achieve dual clamping and positioning of the metal part to be welded, ensuring the stability of the clamping and positioning of the metal part to be welded.

The inner side of the fixture platform has a platform inner groove. The output end of the motor is connected to a threaded rod via a coupling. The outer ring of the threaded rod is rotatably connected to an adjustment inner plate. One end of the first mounting plate is connected to a hydraulic cylinder. The output end of the electric push rod is connected to a welding frame. The lower bottom surface of the hollow slider is connected to a welding head.

One end of the positioning upright plate is connected to a stabilizing frame. One end of the positioning upright plate is connected to a positioning side plate.
[0007] The beneficial effects of this utility model are as follows: When the push plate moves closer to the metal part to be welded under the drive of the clamping plate, the push plate moves the anti-slip pad layer during the movement. Then, the anti-slip pad layer first contacts and adheres to the metal part to be welded. When the clamping plate continues to move under force, the push plate is resisted by the metal part to be welded and slides into the inner groove of the clamping plate through the sliding groove until the clamping plate clamps and positions the metal part to be welded. The anti-slip pad layer increases the friction between it and the metal part to be welded.

[0022] The beneficial effects of this improvement are as follows: after the electric actuator is started, it works and drives the welding frame to move up and down, which is used to adjust the height of the welding head, thereby realizing the adjustable welding use of the welding head.
[0023] To achieve dual clamping and positioning of the metal parts to be welded through the clamping plate and the push plate, and to ensure the stability of the clamping and positioning of the metal parts to be welded:
