Description
Technical Field
The invention belongs to the technical field of grinding wheels, and particularly relates to a fixed disc for a grinding wheel.
Background
The grinding wheel is also called a consolidation grinding tool, and is a consolidation grinding tool which is formed by consolidating common grinding materials into a certain shape (mostly circular, with a through hole in the center) by a binding agent and has certain strength. It is generally composed of abrasive, bond and air holes, which are often referred to as the three elements of a bonded abrasive tool. The grinding wheel is the one with the largest use amount and the widest use range in the grinding tool, rotates at high speed when in use, and can perform coarse grinding, semi-fine grinding, slotting, cutting and the like on the excircle, the inner circle, the plane, various molded surfaces and the like of a metal or nonmetal workpiece.
The emery wheel mainly includes hundred impeller, thousand impeller, silk wheel, throwing aureola, vertical impeller etc. and the main problem that the fixed disk of impeller exists when using lies in: particularly for a hundred-impeller or a vertical impeller, impeller blades are easy to fall off and need to be replaced in time, and the service life of the impeller is short.
Disclosure of Invention
In order to solve the problems, the invention discloses a fixed disk for a grinding wheel, which ensures that an impeller is stably installed and is not easy to fall off, the connection between the impeller disk and a bearing is not tight or loose, and the impeller cannot fall off due to over loose or over close.
A fixed disk for a grinding wheel comprises an impeller disk, a chassis and a connecting disk; the impeller disc is annular, a grinding wheel blade groove is formed in the periphery of the impeller disc, a grinding wheel blade is arranged in the grinding wheel blade groove, the grinding wheel blade groove is a conical groove, a sealing adhesive layer is arranged between the grinding wheel blade groove and the grinding wheel blade, the impeller disc is connected with the chassis through a connecting disc, a bearing connecting ring is arranged in the center of the chassis, and a bearing hole is formed in the center of the bearing connecting ring; an impeller disc is arranged on one side of the base plate, the outer edge of the base plate is fixedly connected with the edge of one side of the impeller disc through a connecting disc, and a gap is formed between the connecting disc and the impeller disc.
Furthermore, the groove depth of the grinding wheel blade groove is 2-5 mm.
Furthermore, the number of the grinding wheel blade grooves is more than 20, and the grinding wheel blade grooves are uniformly distributed on the periphery of the impeller disc in a circumferential mode.
Furthermore, a vertically arranged bulge is arranged in the grinding wheel blade groove. The contact area of the sealant with the impeller groove and the blades is increased by the arrangement of the protrusions, and the adhesive fixation is increased.
Further, an inclined lubricating oil port is formed in the inner side of the bearing connecting ring. The lubricating oil port is arranged, so that lubricating oil can be conveniently lubricated.
The invention has the beneficial effects that:
(1) the invention discloses a fixed disk for a grinding wheel, wherein grinding wheel blades are fixedly arranged in a conical groove through a sealing adhesive layer, so that the blades are stably embedded at the periphery of the grinding wheel and are uniformly distributed in a circumferential manner, the effective grinding of the grinding wheel is realized, the contact between the grinding wheel blades and a groove body is increased while the using amount of sealing adhesive is reduced, meanwhile, the sealing adhesive is convenient to use and simple to operate, the blades are convenient to re-adhere after falling off, and the cost is low.
(2) The whole fixed disk is improved on the basis of the original structure, is convenient to use, saves cost and prolongs the service life of the fixed disk.
(3) The invention discloses a fixed disk for a grinding wheel, which ensures that an impeller is stably installed and is not easy to fall off, the connection between the impeller disk and a bearing is not tight or loose, and the impeller cannot fall off blades of the impeller due to over loose or over close.
