Description

Circumferential rotation type gear shifting device Technical Field The utility model relates to the field of finger joint knife polishing, in particular to a circumferential rotary tooth poking device. Background The existing finger joint knife in the market is a flat rotary cutting tool, and the finger joint knife has the characteristic of small number of teeth, and each finger joint knife is provided with 2-6 alloy teeth. At present, the tooth shifting scheme used when each alloy tooth is ground is circumferential indexing, the circumferential indexing shifts one tooth for grinding, and the grinding amount is different when the circumferential indexing is used due to the accumulated error of the precision of the steel plate body and the thickness of the alloy tooth, so that the grinding amount is more or less, the overall grinding precision is low, and the grinding wheel loss is large. Disclosure of utility model The present utility model is directed to a circumferential rotary type tooth shifting device, so as to solve the above-mentioned problems in the prior art. The utility model solves the technical problems by adopting the following technical scheme: The utility model provides a circumference rotation type dials tooth device, includes bottom plate and servo drive subassembly, the up end of bottom plate rotates installs dials tooth main shaft section of thick bamboo, dial tooth main shaft section of thick bamboo up end fixedly connected with lantern ring spare, demountable installation has the linking arm spare on the extension of lantern ring spare, fixedly connected with dials tooth head ring portion on the linking arm spare, the bottom fixedly connected with spacing bottom plate of dialling tooth head ring portion, it dials tooth connecting portion to rotate on the tooth head ring portion, fixed mounting has dials the tooth needle on one side of dialling tooth connecting portion, is provided with limit baffle portion on the opposite side, it is provided with fixture block portion to dial the fixed on the tooth needle, limit bolt's bottom terminal surface threaded connection has limit bolt, limit bolt's top butt is in limit baffle portion's lower terminal surface. Preferably, a main shaft member is rotatably installed in the inner cavity of the tooth-shifting main shaft barrel, the main shaft member penetrates through the annular part of the sleeve ring member, and a fixing disc for fixing the finger-joint knife is fixedly installed at the top end of the main shaft member. Preferably, the gear shifting main shaft cylinder is fixedly sleeved with a cam piece, a sensor is mounted on the upper end face of the bottom plate, and the sensor senses that a boss of the cam piece drives a servo transmission assembly to drive the gear shifting needle to reset.
