Description

TECHNICAL FIELD

[0002] A numerical control machine tool is an automatic lathe provided with a program control system. The numerical control system can logically process a program provided with control codes or other symbolic instructions, and translate the program into code numbers for input into the numerical control device through an information carrier. After operation and processing, the numerical control device sends various control signals to control the action of the machine tool, and automatically processes the workpiece into a shape and size required by the drawing. The existing clamping plate spacing of the numerical control lathe cannot be adjusted, so that only workpieces of the same size can be clamped, different sizes of workpieces cannot be clamped, and the diversified needs of enterprises cannot be met. Therefore, a solution is needed to solve the above technical problems.

[0003] As disclosed in the patent document CN215657862U, the device drives the first bevel gear and the second bevel gear to mesh and transmit through the driving motor, so that the driving rod drives the clamping plate to move inward to clamp the workpiece, and different sizes of workpieces can be clamped, meeting the diversified needs of enterprises.

[0004] However, the above-mentioned device is fixed by clamping the outer wall of the workpiece, and the existing clamp is used to clamp the tubular workpiece. If the clamping is too loose, the workpiece is easy to fall off, and if the clamping is too tight, the workpiece is easy to deform and be damaged. Secondly, the existing feeding and discharging mode of the tubular workpiece is manually held and conveyed by artificial feeding, which is relatively dangerous, and the artificial feeding needs to control the alignment of the tubular workpiece and the clamp, which consumes a lot of time.
