Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts processing, in particular to a clamp for equipment parts processing production. Background Art

[0002] Fixtures are also called clamps. In a broad sense, any device used to quickly, conveniently and safely install workpieces in any process of the process can be called a fixture. Fixtures are needed when producing and processing mechanical parts.

[0003] Publication (Announcement) No.: CN219649224U discloses a fixture for the production and processing of mechanical parts, which relates to the technical field of mechanical parts processing, including a processing platform, a limiting slide groove is provided on the upper outer surface of the processing platform, and an adjustment mechanism is movably connected inside the upper end of the limiting slide groove. The utility model realizes the horizontal movement of the entire connecting seat through the cooperation between the driving motor, the bidirectional threaded rod and the movable slider, and the bidirectional thread setting of the bidirectional threaded rod ensures that the two groups of connecting seats move in opposite directions, which is convenient for rapid horizontal adjustment according to the size of the workpiece. The horizontal distance of the limit block can be adjusted through the cooperation between the rotating wheel and the rotating rod. Under the connection action of the adjusting rod, the overall angle of the fine-tuning plate changes, so that the clamping plate can effectively clamp the surface of the workpiece, better adapt to the surface of the workpiece, and avoid offset and tilt during processing.

[0004] Although the above scheme has the advantage of preventing the workpiece from being offset and tilted during processing, in actual use, the workpiece is limited only by two sets of clamping plates, and the limiting effect is poor. It is easy to shake when processing mechanical parts. For this reason, we propose a fixture for equipment parts processing and production. Utility Model Content
