Description

Technical Field

[0001] The utility model relates to the field of inclined rail turret machine tools, and more specifically, to a power turret workpiece clamping device. Background Art

[0002] The rotary turret is the general term for the automatic tool changing device and tool driving device in CNC machine tool equipment. The power turret is often used in turning and milling compound machining centers and is one of the core components of the machining center. Multiple tools can be installed on the power turret along the circumference of the cutter disc. The tools are controlled by the program to realize the processes of tool changing, feeding, retracting, and rotary cutting. The existing power turret CNC machine tools only have one chuck for clamping the workpiece. When clamping, the workpiece needs to be manually supported until the three-claw chuck is clamped. When unloading, the three-claw chuck is driven to loosen the workpiece, which can easily cause material falling. The operation is cumbersome and has certain safety hazards.

[0003] In view of the above problems, regarding the technical problem that the existing power turret CNC machine tool clamping device is prone to cause material falling, after a lot of searches, a workpiece clamping device for an inclined rail turret with a patent announcement number of CN216705991U was found, including an inclined rail turret CNC machine tool body, the inclined rail turret CNC machine tool body includes an external shell, and a three-claw chuck arranged on the shell for clamping the workpiece and an axial servo turret for cutting the workpiece, a pre-positioning mechanism coaxial with the three-claw chuck is arranged on the shell, the pre-positioning mechanism is used to support the workpiece when the workpiece is loaded or unloaded, and a driving mechanism for pushing the pre-positioning mechanism closer to or farther from the three-claw chuck is also arranged on the shell, so that the two ends of the workpiece can be supported by the three-claw chuck and the pre-positioning mechanism respectively, and before the three-claw chuck clamps the workpiece, the workpiece can be released at this time, without holding the workpiece until the three-claw chuck is clamped, and when unloading, the three-claw chuck can be driven to directly loosen the workpiece, and material falling will not occur, thereby reducing manual operation steps and improving safety.

[0004] However, the guide wheel of the pre-positioning mechanism of the device needs to contact the workpiece to provide support for the workpiece. However, the CNC machine tool needs to drive the workpiece to rotate at high speed when working. When the CNC machine tool starts, the workpiece starts to rotate. If the guide wheel is still in contact with the workpiece at this time, the high-speed rotating workpiece will have severe friction with the guide wheel, resulting in wear of the workpiece and damage to the guide wheel.

[0005] The utility model can play the role of adjusting the position of the clamping piece and providing support for the workpiece. Utility Model Content
