Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a special-shaped tooling processing fixture. Background Technology

[0002] Irregularly shaped tooling refers to tools and devices used to clamp and fix workpieces with irregular shapes and sizes. Due to the complex shape and irregular surface of the workpieces, traditional standard fixtures and tooling cannot effectively clamp these workpieces, so it is necessary to design and manufacture special irregularly shaped tooling.

[0003] For example, a fixture for irregularly shaped workpieces, disclosed in CN222327966U, includes a support base and several clamping mechanisms for holding irregularly shaped workpieces. These clamping mechanisms are equidistantly arranged at the top edge of the support base. Each clamping mechanism includes a mounting base fixedly connected to the support base, on which a clamping assembly for holding the workpiece is mounted. Several telescopic components are equidistantly arranged on the side of each clamping assembly. The workpiece to be processed is placed between the clamping mechanisms. Then, by rotating a handwheel, the clamping bolt is rotated, and under the action of the threaded sleeve, the clamping base moves closer to the workpiece. The workpiece is then pressed against the clamping plate. Furthermore, by using connecting springs, the extension and retraction of the clamping plate can be adjusted, thus ensuring that multiple clamping plates abut against the workpiece, thereby improving the stability of clamping irregularly shaped workpieces.

[0004] The aforementioned patent proposes that by setting a connecting spring, the extension and retraction adjustment of the clamping plate can be realized, thus ensuring that multiple clamping plates abut against the workpiece, thereby improving the stability of clamping irregular workpieces. However, in actual use, the spring is often in a state of compression and expansion. Over time, the spring will wear out, resulting in a decrease in clamping force and affecting the clamping effect on irregular workpieces. Utility Model Content

A connecting shaft B142 is fixedly installed at the middle end of the adjusting strip 141. The two ends of the connecting shaft B142 pass through the outer surfaces of the side clamping plate A121 and the side clamping plate B122 respectively. Nuts B143 are threadedly connected to the two ends of the connecting shaft B142 and the outer side of the side clamping plate A121 and the side clamping plate B122. When the connecting shaft B142 is rotated, the direction of the adjusting strips 141 and the support plate 144 can be adjusted. The position of the connecting shaft B142 can be fixed by using the nuts B143.

[0027] In this embodiment: the irregularly shaped workpiece is placed inside the clamping frame 11, and multiple sets of diagonal bracing members 14 installed on the outer surface of the base rod 111 support the irregularly shaped workpiece. The moving member 12 and the fixing member 13 are installed according to the position of the irregularly shaped workpiece.
