Description
Technical Field

In the fixture for CNC machining, the rotating operating rod drives the first threaded rod to rotate, and the moving rod drives the right fixed block to move under the rotation of the first threaded rod until the two fixed blocks clamp and fix the tubular workpiece, and the tubular workpiece can be supported under the action of the fixed rod to prevent it from being displaced during drilling.
[0004] Although the CNC machining fixture devices in the prior art, including those mentioned above, can avoid displacement during drilling, there are still some problems in the actual use of such fixtures. When drilling holes in the pipeline, the pipeline will be subjected to a large impact force, which will act on the fixing rod. The material and structural design of the fixing rod are often unable to withstand such continuous and high-intensity impact force, so it is easy to bend or deform. Once the fixing rod is bent, it will affect the stability of the pipeline when it is fixed next time, and may even cause errors in the processing process or damage to the workpiece.
