Description

Rotary disc guide rail mechanism for center hole grinding machine Technical Field The utility model relates to the technical field of center grinding machines, in particular to a rotary disc guide rail mechanism for a center hole grinding machine. Background At present, the machining mode of the center hole mainly comprises two modes, namely scraping and grinding the center hole through a multi-edge center and a center, the mode is low in machining precision of the center hole, low in success rate, time-consuming, labor-consuming and low in working efficiency, and the other machining mode is that the center hole is machined through a center hole grinding machine. The traditional guide rail of the existing center hole grinding machine mostly adopts a sliding friction design, and large resistance is easy to generate under high-load or high-speed working conditions, so that the motion precision is reduced, the abrasion is aggravated, and the service life of equipment is influenced. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a rotary disc guide rail mechanism for a center hole grinding machine. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a revolving disk guide rail mechanism for centre bore grinding machine, includes the grinding machine frame, vertical first guide rail that is provided with on the grinding machine frame front side surface, first guide rail bottom sliding fit has tailstock device, and on the first guide rail and lie in tailstock device top sliding fit have three top clamping units, and the grinding machine frame front side surface lies in the top of first guide rail transversely is provided with the crossbeam, and horizontal sliding fit has the slider on the crossbeam, installs the revolving disk guide rail on the slider, and sliding fit has the revolving disk sliding seat on the revolving disk guide rail, installs the bistrique part on the revolving disk sliding seat. In addition, the structure is preferable that the front side surface of the cross beam is provided with second guide rails in an up-down symmetrical way, and the sliding blocks are transversely matched at the second guide rails in a sliding way. Further, it is preferable that the slider includes a slide seat, and a rotary disk guide rail mounting portion is provided at a front side surface of the slide seat. In addition, preferably, the rotary disc guide rail mounting part is used for mounting the rotary disc guide rail, and the sliding seat is provided with third guide rails which are vertically symmetrically arranged at the position away from the other side surface of the rotary disc guide rail mounting part. In addition, it is preferable that the third guide rail is configured to cooperate with the second guide rail, and roller rows are disposed between the third guide rail and the second guide rail. The utility model has the beneficial effects that the roller row arranged between the cross beam and the sliding block converts sliding friction into rolling friction, so that the guide rail resistance is greatly reduced, the movement precision and bearing capacity of the grinding head component are improved, and the service life of the guide rail is prolonged.
