Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically to a welding fixing clamp that is easy to adjust. Background Technology

[0002] In the field of metal welding, the stability and angle adjustment flexibility of welding fixtures directly affect welding quality and work efficiency.

[0003] Traditional welding fixtures mostly use fixed angle structures or simple hinge devices. Fixed structures cannot achieve dynamic angle adjustment during the welding process, making it difficult to meet the welding requirements of complex workpieces.

[0004] While simple hinge devices can provide limited angle adjustment, they are usually adjusted on a flat surface, resulting in low positioning accuracy, insufficient operability, slow adjustment speed, and difficulty in meeting different welding angles.

[0005] To address this issue, we propose an easily adjustable welding fixture. Utility Model Content

[0006] The purpose of this invention is to provide an easily adjustable welding fixture to address the aforementioned shortcomings in the technology.

A T-shaped groove is formed on the bottom outer wall of one end of the translation plate, and the inner wall of the T-shaped groove is slidably connected to the outer wall of the T-shaped guide rail. A push rod motor is fixedly provided on the outer wall of the corresponding side of the top of the strip positioning plate and the strip adjusting plate. The output end of the push rod motor is fixedly connected to one side of the outer wall of the translation plate. A hemispherical shell is fixedly mounted on one end of the outer wall of the strip positioning plate by a bracket.

[0008] Preferably, positioning blocks are fixedly provided on the outer walls of the top two ends of the translation plate, and moving blocks are provided on the outer walls of the top two ends of the translation plate. Two guide sliders are fixedly provided on the outer walls of the bottom of the moving blocks. A guide groove is opened on the outer wall of the top of the translation plate, and the inner wall of the guide groove and the outer wall of the guide slider are slidably connected.

[0009] Preferably, one side of the outer wall of the positioning block has an internal threaded hole, and one end of the outer wall of the moving block has a first positioning hole. An external threaded rod is inserted into the inner wall of the internal threaded hole and the first positioning hole. The outer wall of the external threaded rod is threadedly connected to the inner wall of the internal threaded hole. The outer wall of the external threaded rod is fixedly connected to the inner wall of the first positioning hole through a bearing.

[0010] Preferably, a rotating handle is fixedly provided on the outer wall of one end of the externally threaded rod.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] The sliding connection structure between the strip adjustment plate and the hemispherical shell via the movable ball, combined with the positioning design of the synchronous push rod, the extrusion plate, and the rubber extrusion pad, allows operators to easily and accurately adjust the angle between the strip adjustment plate and the strip positioning plate. Simply activate the synchronous push rod to push the extrusion plate, and the rubber extrusion pad will press tightly against the movable ball to quickly fix the angle, greatly improving the flexibility of angle adjustment and quickly adapting to different welding angle requirements.
