Abstract
The invention relates to a fixed and movable protection structure of a pneumatic tool engine unit. The fixed and movable protection structure comprises a cylinder group, a handle body structure, and a cylinder fixing pin; the cylinder group comprises a bearing, a rear cover, an elastic pin, a rotor, a blade, a cylinder, a rotor bushing, and a front cover; components are orderly arranged; the front cover and the rear cover are of a flange plane structure; the handle body structure comprises a handle body, a front protection cover and a sealing pad; the cylinder group is arranged in a cavity of the handle body structure, and the cylinder group and the handle body structure are fixed through the cylinder fixing pin, and sealed and fixed through the front protection cover.
Description
Technical field
The present invention relates to the pneumatic tool field, be meant the moving admittedly protection structure of a kind of pneumatic tool cluster engine especially.
Background technology
In the prior art, air tool main working parts is a cluster engine.Cluster engine is by cylinder, rotor, and blade, protecgulum and bonnet are formed (seeing accompanying drawing 1).Existing pneumatic tool be with above-mentioned parts fixing after, in the handle body of packing into, and cooperate through inner chamber with the handle body.But because the size of handle intracoelomic cavity or the reason of precision, cylinder in use often takes place and relatively rotates or move up and down with the handle body in pneumatic tool; And the generation of this situation; The phenomenon of deflection just air tool bearing occurred, the power that bearing is born no longer is uniform axial force, and the damage of bearings phenomenon is serious to making; In this just present pneumatic tool, bearing belongs to the reason of consumable accessory.
Simultaneously, after cylinder produces relative motion with the handle body, caused the torsion of rotor not enough, fluctuation appears in rotating speed simultaneously, and the active force of treating processing component is uneven, and the precision of product is reduced.And when this phenomenon took place, air tool noise strengthened.
Summary of the invention
The objective of the invention is to disclose a kind of technology,, cylinder no longer takes place relatively rotate or move up and down with the handle body so that pneumatic tool in use.And extend the service life of bearing, and noise reduces.
The present invention realizes through following technical scheme:
The moving admittedly protection structure of a kind of pneumatic tool cluster engine includes air cylinder group, handle body structure, cylinder steady pin; Described air cylinder group includes bearing, bonnet, resilient key, rotor, blade, cylinder, rotor bushing, protecgulum; Said above-mentioned parts are installed successively; Described protecgulum and bonnet are Flange Plane formula structure; Said handle body structure includes the handle body, preceding protecting cover and sealing gasket; Described air cylinder group is installed in the handle body structure inner chamber; Said air cylinder group and handle body structure are fixed through the cylinder steady pin, and through preceding protecting cover sealing and fixing.
The invention has the beneficial effects as follows,
1, solved the operator because of the cylinder displacement that improper use produced, make the fit dimension of designing requirement reach the normal torsion of instrument. the output of rotating speed makes operation reach better level.
2, because of the minimizing of axial force, make the bearing can be evenly stressed, the life-span of having improved bearing.

The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing, said embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar parts.Be exemplary through the embodiment that is described with reference to the drawings below, only be used to explain the present invention, and can not be interpreted as limitation of the present invention.
In addition, need to prove, employed term and only be description of the invention for ease in description of the invention about the noun of position relation, and can not be interpreted as limitation of the present invention.
Shown in accompanying drawing 2 to accompanying drawing 4, the moving admittedly protection structure of a kind of pneumatic tool cluster engine includes air cylinder group, handle body structure, cylinder steady pin; Described air cylinder group includes bearing 6, bonnet 5, resilient key, rotor 2, blade 3, cylinder 1, rotor bushing 7, protecgulum 4; Said above-mentioned parts are installed successively; Described protecgulum 4 is a Flange Plane formula structure with bonnet 5; Said handle body structure includes handle body 11, preceding protecting cover 10 and sealing gasket 9; Described air cylinder group is installed in the handle body structure inner chamber; Said air cylinder group and handle body structure are fixing through cylinder steady pin 8, and through preceding protecting cover 10 sealings and fixing.
Although illustrated and described embodiments of the invention; For those of ordinary skill in the art; Be appreciated that under the situation that does not break away from principle of the present invention and spirit and can carry out multiple variation, modification, replacement or modification to these embodiment, scope of the present invention is limited accompanying claims and equivalent thereof.
