Abstract
The utility model discloses a pneumatic bearing detacher. A conical head bolt (5) is arranged in an expansion bolt removing head (7). The utility model is characterized in that a nut (6) is arranged between the conical head bolt (5) and the expansion bolt removing head (7); the top of the conical head bolt (5) is provided with a sleeve (4); a guide bolt (1) is arranged on the top of the sleeve (4); the side surface of the sleeve (4) is provided with a fastening bolt (2); a cover plate (8) of the expansion bolt removing head (7) is connected by threads and is arranged on a pressing plate (10). The utility model has the advantages of simple structure, convenient operation, high production efficiency, and perfectly removing the bearings in blind holes.
Description
(1). technical field
The utility model is particularly related to a kind of device that is used for the blind hole inner bearing on the teardown of engine and the engine.
(2). background technology
At present, manual teardown is adopted in the dismounting of the blind hole inner bearing on machine and the engine.Operating process is to tear the upper end expansion bolt that monkey wrench blocks conical head bolt open head to be placed on the bearing that needs dismounting, with another spanner the conehead nut is screwed along clockwise direction, again monkey wrench is moved to the expansion bolt upper end, block, block the nut of expansion bolt with spanner, along clockwise direction bearing is split out from blind hole.This method is time-consuming takes a lot of work, and efficient is low.
(3). summary of the invention
The purpose of this utility model provides the pneumatic stripping attachment of a kind of bearing.It is simple in structure, and is easy to operate, can dismantle the blind hole inner bearing in good condition, the production efficiency height.
For reaching above-mentioned purpose, conical head bolt is installed in expansion bolt and tears open in the head, it is characterized in that conical head bolt and expansion bolt are torn open nut is set between the head, installs at the top of conical head bolt and connects cover, and guide blot is installed in the top that connects cover; Fastening bolt is installed in the side that connects cover; Expansion bolt is torn being placed on the pressing plate with being threaded with cover plate of head open.
Be fixed with block on the cover plate.
Conical head bolt and expansion bolt are torn open between the head gapped.
Change cover plate into driven gear, driving gear and driven gear engagement, the identical pneumatic stripping attachment of double-canopy plate bearing of promptly forming of all the other structures with the pneumatic stripping attachment of described bearing.
Be fixed with the rifle head that the top has square hole on the driving gear.
Nut is installed below cover plate, and outside cover upper bush is fixed the identical pneumatic stripping attachment of sleeve plate bearing of promptly forming with the pneumatic stripping attachment of described bearing of all the other structures with screw.
The utility model is owing to connect cover in the installation of the top of conical head bolt, gas can be pulled holster is connected on and puts, utilize gas to pull that rifle is torn expansion bolt open head and the bearing that is disassembled is mentioned, therefore easy to operate, can dismantle the blind hole inner bearing in good condition, the production efficiency height per hour can be dismantled about 200 of blind hole inner bearing.
Below in conjunction with accompanying drawing the utility model is described further.
