Planetary gear train type grinding machine capable of realizing direction-changing speed adjustment

Abstract

The invention relates to the field of hard material grinding equipment, in particular to a planetary gear train type grinding machine capable of realizing direction-changing speed adjustment. The planetary gear train type grinding machine comprises a stand and a planetary gear train mechanism, a grinding mechanism and a direction-changing driving mechanism which are arranged on the stand, wherein the planetary gear train mechanism comprises a working table; an inner gear ring, a sun wheel rotating shaft, a first sun wheel, a second sun wheel and multiple planetary wheels are arranged on the working table; the grinding mechanism comprises a rotating shaft; a rotating platform is arranged on the rotating shaft; a grinding wheel is arranged on the rotating platform; the direction-changing driving mechanism comprises a wheel carrier and a driving wheel, a first idle wheel and a second idle wheel which are arranged on the wheel carrier in a rotatable manner; and a handle for connecting the first idle wheel or the second idle wheel to the second sun wheel in a transmission manner by rotating the wheel carrier. The planetary gear train type grinding machine can effectively overcome the shortcomings that the main shaft of the conventional grinding machine is high in speed, the grinding amount is difficult to control, grinding is not uniform, and operation is difficult; and furthermore, the planetary gear train type grinding machine further has the characteristics of simple structure, relatively low manufacturing cost, easiness for maintenance, convenience for operation and the like.

Description

technical field [0001] The invention relates to the field of hard material grinding equipment, in particular to a planetary gear train grinding machine with variable direction and speed regulation. Background technique [0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oil stones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machine tools, abrasive belt grinders, grinding machines and polishing machine etc. The grinding machine can process materials with higher hardness, such as hardened steel, hard alloy, etc.; it can also process brittle materials, such as glass and granite. The grinding machine can be used for grinding with high precision and small surface roughness, as well as high-efficiency grinding, such as powerful grinding. [0003] At present, many s...

AI Technical Summary

Problems solved by technology

[0003] At present, many scholars have carried out in-depth research on grinding machine processing, constructed a lot of transmission mechanisms, and applied for patents, such as the Wuxin disclosed in the Chinese patent with the application number CN102873601A and the publication date being January 16, 2013. Grinding machine mechanism, the application number is CN105817963A, a numerically controlled surface grinder disclosed in the Chinese patent on August 3, 2016, the application number is CN205074878U, and the publication date is disclosed in the Chinese patent on March 9, 2016 A simple modified automatic universal detection cylindrical grinding machine device is an optimization and improvement of the grinding machine mechanism, but the design of these mechanisms is relatively complicated, the mechanism is not compact enough, the spindle speed is relatively high, it is inconvenient to debug, and it is not easy to operate, etc.
