Fully infinitely variable speed numerical control lathe based on double triangular guide rails

Abstract

The invention relates to the technical field of numerical control machine tools, and discloses a full stepless speed change numerical control lathe based on double triangular guide rails. Comprising a machine body, a base and a machine body, the base is an integrated bottom plate, the stability and rigidity of the base are improved, then the stability of the machine body is improved, a supporting plate is arranged on the surface of the base and used for supporting the machine body, and the surface of the supporting plate protrudes out of a forward projection plane in the overlook direction of the base and used for improving the rigidity of the supporting plate. According to the full stepless speed change numerical control lathe based on the double triangular guide rails, through the integral bottom plate design of the base and the design of the supporting plate, the rigidity of the surface of the supporting plate can be improved, meanwhile, the stability of the tool rest in the cutting process is improved, three-point supporting of the first lead screw and the second lead screw can be achieved through the design of the supporting piece, and then the stability of the first lead screw and the second lead screw is improved; the surface of the lathe bed adopts a triangular guide rail design, so that the stability of the workpiece machining process and the workpiece surface machining precision can be improved.

Description

technical field [0001] The invention relates to the technical field of numerically controlled machine tools, in particular to a fully infinitely variable numerically controlled lathe based on double-triangular guide rails. Background technique [0002] CNC machine tool is an automatic machine tool equipped with a program control system. CNC lathe is a kind of CNC machine tool. The CNC lathe fixes the workpiece by using a three-jaw chuck and other fixing mechanisms, and uses a servo motor to drive the workpiece to rotate at a high speed. The surface of the workpiece is machined with a cutting tool. [0003] During the use of the existing CNC lathes, the stability of the lathe body is poor, and the guide rail and rigidity of the track on the surface of the body are poor, which will affect the stability of the workpiece processing process and the precision of the workpiece surface processing. The screw rods for adjusting the X-axis and Y-axis directions of the tool are support...

Problems solved by technology

[0003] During the use of the existing CNC lathes, the stability of the lathe body is poor, and the guide rail and rigidity of the track on the surface of the body are poor, which will affect the stability of the workpiece processing process and the precision of the workpiece surface processing. The screw rods for adjusting the X-axis and Y-axis directions of the tool are supported at both ends. This double-point support will affect the stability of the tool adjustment process and also affect the machining accuracy of the workpiece surface.
