[0002] Numerical control machining refers to a process method for machining parts on numerical control machine tools. It is a mechanical machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve problems such as diverse parts, small batches, complex shapes, and high precision, and to achieve efficient and automated machining.
[0003] When CNC machining shaft-type workpieces, fixtures are required to hold the workpieces stably. However, the clamping components of the fixtures used in CNC machining equipment are not easy to disassemble flexibly, making it difficult to clamp them flexibly according to the size and shape of the workpieces. For some workpieces that are relatively long, it is inconvenient to adjust the clamping depth of the fixture according to the machining requirements, thus affecting the machining efficiency.
[0004] There is an urgent need for a CNC machining center fixture for machining shaft-type workpieces to address the technical deficiencies mentioned above. Utility Model Content

[0014] (2) By setting up a fixture body, a clamping block, a clamping cylinder and a clamping pad, the fixture body has a circular through groove structure inside, and shaft workpieces can be inserted into the fixture body. The clamping cylinder inside the fixture body pushes the clamping block to stably clamp and limit the workpiece. The clamping pad on the clamping block is made of rubber to enhance the stability of clamping. The clamping block can be disassembled and replaced from the fixture body, thereby expanding the clamping range.
[0015] (3) By setting up a clamping block, a clamping seat, mounting bolts and a connecting block, the clamping block can clamp and limit the workpiece by pressing it against the outside of the workpiece. The clamping block can be removed and replaced from the clamping seat. The clamping block can be replaced with a suitable shape, size and structure.
