Description

Technical Field

[0002] CNC machining centers are high-efficiency automated machine tools that are composed of mechanical equipment and CNC systems and are suitable for machining complex parts. CNC machining centers are one of the most productive and widely used CNC machine tools in the world. CNC machine tools generally clamp the workpiece on a three-jaw chuck. When the workpiece is long, the high-speed rotation of the three-jaw chuck will cause eccentric movement of the workpiece, causing the workpiece to vibrate greatly. Therefore, before machining a long workpiece, a corresponding auxiliary device is required to assist in limiting the long workpiece to prevent the long workpiece from vibrating during the machining process.

[0003] Publication number "CN217859960U" provides a CNC machine tool processing auxiliary device, which uses a clamping block to achieve limited clamping of a longer workpiece, thereby ensuring the stability of the workpiece during the rotation of the three-jaw chuck, avoiding the jitter of the longer workpiece during high-speed rotation, and the clamping position of the workpiece can move with the moving block, so that the clamping position can be adjusted following the movement of the cutting position, which can make the clamping effect at the cutting position of the workpiece better and make the cutting accuracy of the longer workpiece higher.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although this CNC machine tool processing auxiliary device can make the cutting processing of longer workpieces more accurate, the exposed outer surfaces of the lead screw and the adjusting rod are prone to debris adhesion during the turning process of the workpiece by the CNC machine tool. At this time, the lead screw and the adjusting rod with debris adhesion will cause the moving block and the horizontal plate to get stuck during the movement, so it has low practicality.
