Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a general-purpose tooling and fixture. Background Technology
[0002] Fixtures are tools used to clamp workpieces, which can fix and clamp the workpieces so that they can be processed better. Fixtures are an indispensable part of machining.
[0003] In daily production and processing, it is often necessary to clamp workpieces. When machining workpieces, they need to be clamped onto specialized tooling fixtures, and then the tooling is rotated, translated, or otherwise manipulated to facilitate the machining of the workpieces. In order to cope with situations where there are many types of the same series of products (such as workpieces) but small quantities, equipment generally needs to be compatible with multiple workpieces to reduce the overall equipment investment cost. That is, ideally, a single tooling fixture can be used to clamp multiple models of workpieces from the same series.
[0004] For example, the prior art Chinese patent publication number "CN221792454U" provides a universal tooling fixture, including a base that is placed horizontally. A fixing plate is fixed to one end of the top of the base, and a clamping fixture is fixed to the top of the fixing plate. A support plate is fixed to the other end of the top of the base, and a telescopic electric push rod is fixed to one side of the support plate. Another movable fixture is fixed to one end of the electric push rod.
[0005] The device allows the first limiting plate, the second limiting plate, and the third limiting plate to rotate freely, thereby adjusting the position of the first limiting plate so that it can contact different workpieces and clamp different types of workpieces. This avoids the need to disassemble the original fixture and install the required fixture when changing to a different type of tooling fixture.
[0006] Existing tooling fixtures have limited adjustment methods, making manual or motor-driven adjustments inconvenient. They also lack sufficient clamping tightness, leading to loosening and unstable workpiece clamping. Furthermore, it is inconvenient to adjust the height of the clamping structure for workpieces of different heights, affecting the clamping tightness for workpieces of varying heights.
[0007] Therefore, a universal tooling fixture is proposed. Utility Model Content

[0013] Furthermore, the base is horizontally positioned, the support legs are L-shaped, the rotating rod is a threaded rod structure and is horizontally positioned, the moving groove and the moving plate are both rectangular plate structures, and the motor is installed at the outer end of the base.
[0014] Furthermore, the rotating frame has a cross-shaped structure and is vertically arranged on the outside of the top clamping plate. The first connecting hole has a threaded hole structure, and the inner end of the first bolt abuts against the outside of the base.

Therefore, the tooling fixture can be adjusted electrically or manually. The rotating rod and the base are fastened together by the first bolt and the top plate, and the movable plate and the base are fastened together by the nut and the limiting rod, thereby ensuring that the clamping block firmly and stably clamps the workpiece.
[0020] 2.

The clamping of different workpieces is relatively flexible. Attached Figure Description
