Description
Technical field
The utility model relates to pneumatic wrench field, specifically a kind of cylinder of pneumatic wrench.
Background technique
Pneumatic wrench mainly provides high moment of torsion to export minimum consumable tool, be widely used in assembling line and maintenance dismounting nut occasion, cylinder is rotor and blade working environment part, it is the important accessory of pneumatic wrench, pneumatic wrench cylinder is because of connection function direct with rotor blade, operationally be vulnerable to rotor blade and rotate the wearing and tearing bringing internal end surface, the using effect that impact is overall.
Model utility content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of cylinder rotary through-hole wall to be provided with the pneumatic wrench cylinder of the Double-deck air cylinder structure of wearing layer.
For achieving the above object, the utility model provides following technological scheme:
A kind of cylinder of pneumatic wrench, comprise cylinder body, the rotor through hole with outer margin contour bias is provided with in described cylinder body, described rotor through-hole wall is provided with wearing layer, described wearing layer and cylinder body are fixed as one, described cylinder body is provided with fixed via, described fixed via and the rotor through hole center of circle are point-blank, described cylinder body two circular end face is respectively provided with two ventilating grooves of relative fixed via and rotor through hole center of circle straight line symmetry, described ventilating groove end face is provided with strip through-hole, and described cylinder body outer wall is provided with three and stirs through hole.
As further program of the utility model: described wearing layer material is stainless steel, described cylinder body material is aluminum alloy.
Compared with prior art, the beneficial effects of the utility model are: the rotor through-hole wall directly contacted with rotor blade by pneumatic wrench cylinder is provided with one deck stainless steel wearing layer, the face smooth by stainless steel and the physical property of excellence, make overall wear resistance be improved and smoothly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the upper-end surface schematic diagram of the utility model embodiment.
Fig. 3 is the generalized section of the utility model embodiment.
In Fig. 1 ~ Fig. 3: cylinder body 1, wearing layer 2, rotor through hole 101, fixed via 102, ventilating groove 103, strip through-hole 104, stir through hole 105.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, in the utility model embodiment, a kind of cylinder of pneumatic wrench, comprise cylinder body 1, the rotor through hole 101 with outer margin contour bias is provided with in described cylinder body 1, described rotor through-hole wall is provided with wearing layer 2, described wearing layer 2 is fixed as one with cylinder body 1, described cylinder body 1 is provided with fixed via 102, described fixed via 102 and rotor through hole 101 center of circle are point-blank, described cylinder body 1 liang of circular end face is respectively provided with two ventilating grooves 103 of relative fixed via 102 and rotor through hole 101 center of circle straight line symmetry, described ventilating groove 103 end face is provided with strip through-hole 104, described cylinder body 1 outer wall is provided with three and stirs through hole 105, described wearing layer 2 material is stainless steel, described cylinder body 1 material is aluminum alloy.
Principle of the present utility model is: rotor through hole 101 inwall directly contacted with rotor blade by pneumatic wrench cylinder body 1 is provided with one deck stainless steel wearing layer 2, the face smooth by stainless steel and the physical property of excellence, make overall wear resistance be improved and smoothly.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
