Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically to a workpiece clamping mechanism for CNC lathes. Background Technology

[0002] A CNC lathe is a digitally controlled lathe that performs automated machining through a control terminal and a program control system installed inside the lathe. When machining parts on a CNC lathe, the first step is to fix the position of the workpiece. On a CNC lathe, a clamping mechanism is usually used to limit the position of the workpiece.

[0003] A workpiece clamping mechanism for a CNC lathe, application number "CN202420707805.9", involves placing the workpiece in a storage slot. The workpiece then presses the lifting plate completely into the bottom slot and into contact with a pressure sensor. Upon detecting the pressure, the pressure sensor transmits an electrical signal to a controller. The controller first drives two servo motors, causing the protruding plates on the two clamping blocks to horizontally position the workpiece on both sides. Two seconds later, the controller drives two electric telescopic rods to retract, vertically positioning the workpiece on the two top blocks. This prevents the workpiece from wobbling or tilting at one end during subsequent processing, ensuring processing stability and improving accuracy. However, in practice, metal chips generated during workpiece processing can easily fall onto the screw, affecting the movement of the inner slider and consequently impacting clamping. Utility Model Content

[0004] The purpose of this utility model is to provide a workpiece clamping mechanism for CNC lathes, which can drive the extrusion plate to move through the mounting column, mounting groove, transmission motor, lead screw, and moving rod to clamp the workpiece. Compared with the prior art, there will be no metal chips affecting the lead screw, and thus no impact on clamping.

Several springs are fixedly connected to the lower end of the mounting plate, and a clamping plate is fixedly connected to the lower end of the springs.

[0007] According to the workpiece clamping mechanism for a CNC lathe, a moving groove is provided on one side of the mounting column, a limiting groove is provided on the outer side of the moving groove, a limiting rod is symmetrically fixedly connected inside the limiting groove, and the moving rod is slidably connected to the surface of the limiting rod.
