Planetary wheel type flexible abrasive disc

Abstract

The invention relates to a planetary wheel type flexible abrasive disc. The planetary wheel type flexible abrasive disc comprises a shell body, wherein the shell body is defined by a base plate, a top plate, a left side plate and a right side plate, a first hole and five second holes are formed in the top pate, five third holes are formed in the base plate, an abrasive disc set is fixed in the shell body, and four clamping wheels are evenly arranged between the shell body and the abrasive disc set; the abrasive disc set comprises an inner gear ring, a driving gear and driven abrasive bundles, a motor is arranged over the driving gear, the motor is fixed on the top plate, a shaft of the motor penetrates through the first hole to be fixedly connected to the driving gear, driven gears are arranged on the upper portions of the driven abrasive bundles respectively, square grooves are formed in the lower ends of the driven abrasive bundles respectively, a baffle ring is arranged at the lower end of each square groove, a square cleaning rod is arranged in each square groove, an end block is arranged at the upper end of each cleaning rod and is clamped in the corresponding square groove, the lower end of each cleaning rod penetrates through the corresponding third hole and is provided with an abrasive brush, and the lower portion of each cleaning rod is sleeved with a compression spring. According to the planetary wheel type flexible abrasive disc, self-adaptation can be achieved according to the shape of a part to be polished, polishing area is large, and polishing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a planetary wheel type flexible grinding disc. Background technique [0002] A large number of production raw materials or formed and semi-formed products are often placed in the production workshop. The accumulation of these products or raw materials not only affects production, takes up a lot of space, and is prone to rust if they cannot be used in time, especially in high temperature and high temperature conditions in the workshop. in a wet environment. [0003] Iron rust is a kind of brownish-red material, it is not so hard as iron, it is easy to fall off, after a piece of iron gets rusty completely, its volume can expand by 8 times. If rust is not removed, this spongy rust is especially good at absorbing water, and iron will rust faster. The amount of metal lost due to corrosion in our country is astonishing every year, which seriously wastes limited resources. ...

AI Technical Summary

Problems solved by technology

[0004] However, in industrial production, the stock of products or raw materials is large, and the workload of removing rust is also large. In the prior art, hand-held electric grinders are often used for grinding. Due to the small area of ​​this type of grinding head, the grinding efficiency is low, especially for three-dimensional rust. Products, such as valve casings, bonnets, etc., because the rusted surfaces of the corroded products are not on the same plane, the grinding direction needs to be changed continuously during grinding, which makes it difficult to clean efficiently
