CNC machine tool

Abstract

The invention discloses a numerical control machine tool. The Key points of the technical scheme of the numerical control machine tool are that the numerical control machine tool comprises a machine frame, a clamp, a sliding saddle, a longitudinal sliding rail, a sliding plate and a rotary knife rest; a first rail seat and a second rail seat are arranged on the machine frame in parallel, and the second rail seat is higher than the first rail seat; transverse sliding rails perpendicular to the longitudinal sliding rail are arranged on the first rail seat and the second rail seat respectively; and the sliding saddle is slidingly connected between the first rail seat and the second rail seat; the top surface of the transverse sliding rail on the first rail seat and the top surface of the transverse sliding rail on the second rail seat are both horizontal surfaces so as to enable the contact surfaces of the sliding saddle and the transverse sliding rails are also horizontal planes, so thatthe gravity of the sliding saddle directly acts on the top surfaces of the transverse sliding rails; the gravity direction of the sliding saddle is perpendicular to the top surfaces of the transversesliding rails, so that the sliding saddle is not prone to generating the trend of longitudinal movement and vertical movement in the moving process, and therefore the side walls of the transverse sliding rails are not prone to deformation and even damage, and machining precision of the numerical control machine tool is guaranteed to a certain degree.

Description

technical field [0001] The invention relates to the technical field of workpiece processing equipment, in particular to a numerically controlled machine tool. Background technique [0002] CNC machine tool is an automatic machine tool equipped with a program control system. [0003] At present, the Chinese patent with the notification number CN205817305U discloses a double-headed CNC machine tool, which includes a bed with an inclined surface, a slide rail is arranged on the inclined surface, and the top surface of the slide rail is parallel to the inclined surface. A cross sliding table is slidably connected to the slide rail, and the top surface of the cross sliding table is parallel to the inclined surface, a rotary tool rest is arranged on the cross sliding table, and a Z-axis motor is arranged on the bed, and the Z-axis motor is used for Drive the cross slide to slide on the slide rail, the cross slide is provided with an X-axis motor, the X-axis motor is used to drive...

AI Technical Summary

Problems solved by technology

The first force component makes the cross slide have a tendency to slide downward along the slope, so that when the CNC machine tool is used to process the workpiece, the side wall of the slide rail is squeezed from the cross slide, so that the side of the slide rail The wall is prone to deformation or even fracture

In this way, when the cross slide rail moves on the slide rail, it is easy to deviate in the longitudinal direction, which has a great impact on the machining accuracy of the CNC machine tool.
