Rapid connecting structure of grinding disc of grinding machine tool

Abstract

The invention relates to the technical field of grinding machine tools, and discloses a rapid connecting structure of a grinding disc of a grinding machine tool. The rapid connecting structure comprises a fixing block and a grinding disc body, wherein a motor is fixedly installed in the middle of the right side face of the fixing block; a rotating shaft A is transversely and rotationally arranged in the middle of the motor; the rotating shaft A transversely and rotationally penetrates through the middle of the fixing block; a connecting groove is formed in the middle of the left side face of the fixing block; a connecting sleeve is inserted into an inner cavity of the connecting groove in a sliding mode; a transmission shaft transversely and rotationally penetrates through the middle of the connecting sleeve; the outer wall of the transmission shaft is sleeved with the grinding disc body; and a rotating shaft groove is formed in the middle of the right side face of the transmission shaft. According to the rapid connecting structure, a pull rope is pulled out of an inner cavity of a limiting sliding groove in the rotating process of an annular gear, at the moment, the pull rope can drive a connecting pin to be pulled out of an inner cavity of a connecting pin hole, after the annular gear is reversely rotated, a spring can push the connecting pin into the inner cavity of the connecting pin hole through elastic force, so that the stability of the grinding disc after connection is effectively improved, and meanwhile, the grinding disc is more convenient and faster to connect and disassemble.

Description

technical field [0001] The invention relates to the technical field of grinding machine tools, in particular to a quick connection structure for a grinding disc of a grinding machine tool. Background technique [0002] Grinding is the cutting process of machining the surface of workpieces with high-speed rotating grinding wheels and other abrasive tools. Grinding is used to process the internal and external cylindrical surfaces, conical surfaces and planes of various workpieces, as well as special and complex forming surfaces such as threads, gears and splines. [0003] The grinding disc on the grinding machine will also be worn during use. Therefore, the grinding disc on the grinding machine also needs to be replaced frequently. But the drill clip needs to be manually tightened and fixed, and the quick connector needs to be manually pressed on the end of the quick connector to clamp the frosted disc. These two connection structures still have some inconvenience in the actu...

Problems solved by technology

[0003] The grinding disc on the grinding machine will also be worn during use. Therefore, the grinding disc on the grinding machine also needs to be replaced frequently. But the drill clip needs to be manually tightened and fixed, and the quick connector needs to be manually pressed to the end of the quick connector to clamp the frosted disc. These two connection structures still have some inconvenience in the actual use process. Disk replacement is slow and requires a certain amount of physical effort
