Polishing device having environmental protection function and used for gear blank machining

Abstract

The invention discloses a polishing device having an environmental protection function and used for gear blank machining, and belongs to the technical field of gear machining. The polishing device comprises a polishing barrel, a polishing cavity is formed in the upper end of the polishing barrel, a polishing rotary barrel is arranged in the polishing cavity, a polishing motor is arranged in the center of the bottom of the polishing barrel, an output shaft of the polishing motor penetrates through the bottom of the polishing barrel, the upper end of the output shaft of the polishing motor is fixedly connected with the center of the bottom of the polishing rotary barrel, polishing liquid is loaded in the polishing cavity, and a polishing medium is loaded in the polishing rotary barrel. The polishing medium is driven by the polishing rotary barrel to rotate, so that a to-be-polished gear blank is ground and polished; through an arranged evaporation heat pipe, heat generated by grinding and polishing can be quickly guided out close to the to-be-polished gear blank, the temperature of the to-be-polished gear blank is kept stable, the polishing effect is guaranteed, a cooling liquid circulating device does not need to be additionally arranged, the grinding energy consumption is greatly reduced, the subsequent treatment step of the cooling liquid is omitted, and the polishing device is more energy-saving and environment-friendly.

Description

Technical field [0001] The present invention relates to the field of gear processing, and more particularly to a polishing apparatus for a tooth blank having an environmentally friendly function. Background technique [0002] The gear machining before the toothed machining is called the tooth blank processing, the inner hole (or journal), the end surface or outer circle is often a gear machining, measurement, and assembly reference, and the accuracy of the toothed blank is important to the machining accuracy of the gear. Impact. Therefore, the tooth blank has an important position throughout the gear machining. [0003] In the teeth, the main requirements are guaranteed to ensure the size accuracy and shape accuracy of the reference hole (or journal), the positional accuracy of the reference end surface relative to the reference hole (or journal), the processing of the high-precision gear, is required to be in the teeth The final step of processing is polished to the tooth blank,...

AI Technical Summary

Problems solved by technology

[0004] There are more and more existing micro-mechanical equipment. The gears used in these equipment are small in size. In mass production, the polishing work for the tooth blank is very cumbersome, and the coolant used in the polishing process needs to continuously provide power circulation. , and the used coolant needs to be purified and reused due to the existence of grinding debris, which consumes a lot of energy and greatly increases the cost of polishing
