Description
Technical Field
[0001] The utility model relates to the technical field of numerical control tooling, in particular to a CNC processing clamping device for a frame product. Background Art
[0002] CNC tooling, or CNC tooling, is a device used in CNC machining to position and clamp workpieces. The design and selection of tooling has an important impact on the quality and efficiency of CNC machining.
[0003] For example, the main functions of CNC tooling include: positioning, that is, ensuring the accurate positioning of the workpiece on the CNC machine tool through the CNC tooling, which helps to ensure the accuracy and consistency of processing. Clamping, that is, using the clamping mechanism of the CNC tooling to firmly fix the workpiece on the machine tool table to prevent the workpiece from moving or deforming during the processing. Reusability, that is, the tooling is usually reusable, which means that it can be reused in multiple processing processes, thereby reducing manufacturing costs. Improve efficiency, that is, through reasonable tooling design, processing efficiency can be improved, clamping time and auxiliary operations can be reduced.
[0004] Specifically, CNC tooling can be either special tooling or general tooling. Special tooling is customized according to the shape and size of a specific workpiece, while general tooling can adapt to a variety of different workpieces.
[0005] Based on this, Chinese patent CN116852132A discloses a tooling for high-speed CNC milling of thin-walled parts, which includes a base, the inner wall of the base is rotatably connected to a bidirectional threaded rod through a bearing, and the bidirectional threaded rod is rotated to perform relative limiting through the connection relationship between the threaded block and the inner wall of the base, and through grooves are provided on both sides of the base, and the C-shaped connecting block drives the flexible clamping block to move close to the workpiece to be processed to prepare for clamping, so that metal debris generated during milling is difficult to enter the base to affect the rotation of the bidirectional threaded rod, and a force-bearing hole is provided to facilitate the insertion of a lever to leverage the force to push the rotating rod to drive the bidirectional threaded rod to rotate, and the air source used by the air gun is connected through the air inlet joint, and air is injected into the cylinder through the air hole to push the piston rod to drive the flexible membrane to fit the surface of the part, so as to increase the force area and avoid damage to the part due to uneven force during clamping.

Specifically, the CNC milling tooling disclosed in the prior art is for thin-walled workpieces, while the frame products currently need to be clamped for use in the automated processing of CNC machine tools; therefore, more attention needs to be paid to the stability of the clamping. In addition, the existing CNC tooling also has the disadvantages of complex structure and high production cost, which is not conducive to reducing production costs. Furthermore, the existing CNC tooling also needs to consider whether there are enough product processing positions, whether the clamping positions are reasonable, and the stability of the clamping.
