AI Technical Summary

Technical Problem

After a long time of use, dust and impurities are easily accumulated on the mesh cover, which leads to airflow obstruction and affects the cooling effect of the spindle, which may lead to excessive spindle temperature and affects performance and service life.

Method used

A heat dissipation device including a heat dissipation mechanism, a cooling mechanism, a scraping mechanism and a blow-off mechanism is designed. The heat dissipation mechanism dissipates heat through the fan blade and the filter plate, the cooling mechanism cools through the spiral plate and the cooling chamber, the scraping mechanism scrapes dust on the filter plate through the scraper and the moving block, and the blowing mechanism blows dust on the filter plate through the spray head.

Benefits of technology

By effectively scraping and blowing off dust on the filter plate, the air flow is not hindered, the cooling efficiency of the spindle is improved, the temperature is too high, and the service life is extended.

Abstract

The invention relates to the technical field of motor spindles, in particular to a numerically-controlled machine tool high-speed motor spindle heat dissipation device which mainly comprises a high-speed motor, a heat dissipation mechanism, a cooling mechanism and a scraping mechanism, the output end of the high-speed motor is fixedly provided with a spindle through a coupler, the heat dissipation mechanism is arranged on one side of the high-speed motor, and the cooling mechanism is arranged on the outer side of the spindle. The scraping mechanism is arranged below the main shaft and comprises a moving block located below the main shaft and a blowing mechanism, and the blowing mechanism is arranged on one side of the moving block. When a main shaft rotates, a fixing ring and a protruding block are driven to rotate, under the combined action of the protruding block and an elastic piece, a moving block and a fixing strip move up and down in a reciprocating mode, the moving block drives a connecting rod, a rotating shaft and two scraping plates to rotate in an arc-shaped reciprocating mode through a hinge rod, the two scraping plates scrape dust on the surface of a filter plate, and it is guaranteed that the dust is not prone to blocking filter holes; therefore, the effective cooling effect of the whole system on the spindle is improved, the spindle temperature is not too high, and the performance and the service life of the spindle are improved.
