Numerical control equipment

Abstract

The invention relates to numerical control equipment. A main support frame is in a closed loop structure, and the opening of the structure faces towards the vertical direction; an X-direction front guide rail and an X-direction back guide rail which are mutually matched are arranged between the main support frame and an X-direction sliding seat; a Z-direction guide rod is a round guide rod, and the Z-direction guide rod only can be installed together with a Y-direction sliding seat in an up-and-down movement way; the numerical control equipment is further provided with a rotation stopping structure which is used for preventing the Z-direction guide rod from rotating along the horizontal direction of the axial line of the guide rod; the rotation stopping structure comprises a third rotation stopping block and a third spring; a blind hole is formed in the side surface of the Z-direction guide rod; a rotation stopping groove which is matched with the third rotation stopping block is formed in a guide hole which is matched with the Z-direction guide rod; the third spring is installed between the bottom surface of the blind hole and the third rotation stopping block; and one side of the third rotation stopping block, which is far from the spring, is protruded out of the periphery of the Z-direction guide rod and matched with the rotation stopping groove. The numerical control equipment has the advantages of good stability and difficulty in generating unbalanced torque when a main processing head is moved up and down.

Description

Background technique [0001] Existing numerical control equipment, one is workbench movement. For example, in the invention patent with the application number of 201010284237.9, a CNC gantry vertical compound machine tool is disclosed, including a base, a workbench, and a column. The column is movably connected by a column guide rail or fixedly connected with a composite beam through a fastener. The composite beam passes through the beam. There are more than 2 sliding saddles that are movably connected or fixedly connected by fasteners, and the sliding saddle is movably connected with the main shaft device through the ram guide rail; the base, column, composite beam, and main shaft device are equipped with screw drive devices, and the screw drive The devices are all connected to the electrical numerical control device. [0002] One is the gantry movement. For CNC equipment with this structure, one way is to drive the gantry to move back and forth. The driving mechanism needs ...

AI Technical Summary

Problems solved by technology

In the moving column type CNC machining center of this invention, since the longitudinal column on which the main shaft is installed is only supported on one side, the main shaft has poor stability, inaccurate positioning, poor movement and too fast movement during movement.
