A high-efficiency CNC gear grinding machine that can realize multi-point grinding and automatic centering

Abstract

The invention relates to the technical field of grinding equipment, and particularly provides an efficient numerical-control gear grinding machine capable of realizing multi-point grinding and automatic centering. The efficient numerical-control gear grinding machine comprises a machine bed, a large vertical pillar and a small vertical pillar, wherein a grinding wheel frame is arranged on the large vertical pillar, a grinding wheel is fixed to the grinding wheel frame, and at least four grinding sections are annularly arranged on the outer peripheral surface of the grinding wheel at equal intervals; a vertical pneumatic guide rail is fixed to a first sliding block, a second sliding block is arranged on the pneumatic guide rail, and a position sensor is fixed to the second sliding block and connected with a numerical-control system. According to the efficient numerical-control gear grinding machine capable of realizing multi-point grinding and automatic centering, the multiple grinding sections are arranged on the grinding wheel and can realize multi-point grinding and grind multiple tooth shapes simultaneously, the grinding efficiency is improved, and the time for replacing the grinding wheel is shortened. On-line measurement and automatic centering can be realized, labor is saved, the situation that workpieces are scrapped due to manual centering is avoided, and the machining efficiency and machining accuracy are improved.

Description

technical field [0001] The invention relates to a grinding processing equipment, in particular to a high-efficiency numerical control gear grinding machine capable of realizing multi-point grinding and automatic centering. Background technique [0002] Gear transmission is widely used for its stable transmission and high transmission precision. Therefore, the precision and efficiency of gear processing are related to the running precision of the machine. In the gear processing process, gear grinding can improve the running accuracy of the gear. The gear grinding mainly uses the grinding wheel on the CNC gear grinding machine to finish the tooth profile of the gear, so as to obtain the accuracy requirements of the tooth profile, tooth direction and tooth surface. . However, the grinding wheel of the existing CNC gear grinding machine is single-tooth grinding, that is, there is only one grinding section on each grinding wheel, and the grinding section ring is arranged on the ...

AI Technical Summary

Problems solved by technology

However, the grinding wheel of the existing CNC gear grinding machine is single-tooth grinding, that is, there is only one grinding section on each grinding wheel, and the grinding section ring is arranged on the outer circumferential surface of the grinding wheel. One tooth groove of the gear is finely ground, and the processing efficiency is very low

Moreover, because the grinding wheel grinds the workpiece for a long time, the surface of the grinding section will be worn, and the grinding wheel needs to be replaced frequently, which further reduces the processing efficiency.

[0003] In addition, when the existing gear grinding machine grinds the workpiece, it needs experienced workers to align the grinding workpiece and the grinding wheel multiple times, that is, every time a tooth shape is ground, manual alignment must be carried out, which not only consumes Labor, and it is very easy to cause the workpiece to be scrapped due to inaccurate alignment
