Polishing head with shock absorption function and polishing machine

Abstract

The invention discloses a polishing head with a shock absorption function. The polishing head comprises a spindle box, a sleeve, a spindle and a shock absorption device arranged between the sleeve and the spindle, wherein the shock absorption device comprises an installation body, a fixing disc, a slide bushing movably arranged between a supporting body and a partition plate of the installation body, a movable body arranged in an installation groove formed in the installation body in a sleeved mode, an annular cover arranged in the movable body in a sleeved mode, a first steel ball arranged in a second notch, a second steel ball arranged in a third notch of a notch part, and a first spring arranged in a locking groove of the notch part. The polishing head is simple in structure, has the shock absorption function and meanwhile has the advantages of being low in nose, strong in power, good in performance, long in life, light and handy in machine body, sturdy and durable, especially, shock at the joint of two stone slab ridge plates is small, and the rotating speed can be adjusted in a self adaptive mode according to the shock.

Description

technical field [0001] The invention relates to the technical field of stone processing, in particular to a grinding head and a polishing machine with shock-absorbing functions. Background technique [0002] A grinder is a manual power tool used for grinding metal surfaces. It is widely used in the fine grinding treatment of flat surfaces in the furniture industry, mold industry, and product parts. The key to the operation of the grinder is to try to get the maximum polishing rate so as to remove the damaged layer produced during polishing as soon as possible. At the same time, it is necessary to ensure that the polishing damage layer will not affect the final observed tissue, that is, it will not cause false tissue. The former requires the use of coarser abrasives to ensure a greater polishing rate to remove the polished damage layer, but the polishing damage layer is also deeper; the latter requires the use of the finest materials to make the polishing damage layer shallo...

Problems solved by technology

The former requires the use of coarser abrasives to ensure a greater polishing rate to remove the polished damage layer, but the polishing damage layer is also deeper; the latter requires the use of the finest materials to make the polishing damage layer shallower, but the polishing damage layer is deeper. low rate

In the usual stone slab polishing, people put multiple stone slabs on the workbench for polishing, which usually causes overheating, large vibration, loud noise and other defects during polishing, especially when transferring from one stone slab to another During transitional polishing of the stone slabs, the edge plates of the two stone slabs are not tightly combined, causing the grinding head to vibrate, resulting in damage to the edge plates of the slabs
