Abstract
The utility model discloses an impact structure of a pneumatic impact wrench, which comprises a main shaft, an impact block, an impact sleeve and an impact frame, wherein the impact block is sleeved at one end of the main shaft, and the impact block is arranged inside the impact frame, one end of the impact block is fixedly connected with the impact frame through the impact sleeve, and the other end of the impact block is fixedly connected with the impact frame through a spline; the impact block comprises an impact body and a pin body which are integrally formed, the axial length of the pin body is larger than that of the impact body, and the pin body is arranged on the outer side of the impact body; and the inner side of the impact body is matched with one end of the main shaft. In the utility model, the pin shaft and the impact block are integrally formed, pin shaft connection is avoided, and weak parts of the impact structure are replaced. Therefore, the service life of the impact structure is prolonged. A double-hammer structure in the utility model is arranged symmetrically, so that the work of the impact structure is smoother, the rigidity of the entire impact structure can be increased, and the smoothness and the impact service life of the impact structure are increased.
Description
Technical field
The utility model relates to a kind of impact type pneumatic wrench, is specifically related to a kind of striking structure of impact type pneumatic wrench.
Background technology
The striking structure of existing impact type pneumatic wrench as shown in Figure 1, promptly there be two hammering of pin to hit structure, it hits body 8 and impacts between the frame 6 and generally achieves a fixed connection by shank 10, therefore the performance of shank 10 has determined the service life of striking structure, in case shank 10 lost efficacy, striking structure just can't use.
For this reason, a kind of no pin list hammering as shown in Figure 2 occurred and hit structure, promptly an end of main shaft 14 is provided with a taping block 13, and taping block 13 directly is connected with impact frame 11 and impact cover 15, but the work that structure is hit in this no pin list hammering is steady inadequately.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of striking structure of impact type pneumatic wrench, and it can prolong the service life of striking structure.
For solving the problems of the technologies described above, the technical solution of the striking structure of the utility model impact type pneumatic wrench is:
Comprise main shaft, taping block, impact cover, impact frame, an end of main shaft is arranged with taping block, and taping block is arranged at and impacts in the frame; One end of taping block is fixedlyed connected with the impact frame by impacting cover, and the other end of taping block is fixedlyed connected with the impact frame by spline; Taping block comprises strike body, shank, hits body and shank and is formed in one, and the axial length of shank is greater than the axial length that hits body.
One end of described main shaft is provided with two taping blocks, and two taping blocks are symmetrical arranged with respect to the pivot of main shaft.
The technique effect that the utility model can reach is:
The utility model is one-body molded with bearing pin and taping block, has cancelled the bearing pin connection, has replaced the weak part of striking structure, thereby can prolong the service life of striking structure.
The two hammering of the present utility model hits the symmetrical configuration setting, can make the work of striking structure more steady, increases the rigidity of whole striking structure, increases the stationarity and the strike life-span of striking structure.
The utlity model has advantages such as stable working, impulsive force is big, the life-span is long.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is that prior art does not have the pin list and beats and to hit the decomposing schematic representation of structure;
Fig. 2 is that prior art has two hammering of pin to hit the decomposing schematic representation of structure.
Fig. 3 is the stereogram of the striking structure of the utility model impact type pneumatic wrench;

Fig. 5 is a decomposing schematic representation of the present utility model.
Description of reference numerals among the figure:
1 for impacting frame, and 2 is spline,
3 is taping block, and 4 is main shaft,
5 for impacting cover, and 6 are the impact frame,
7 is spline, and 8 are the strike body,
9 is main shaft, and 10 is shank,
11 for impacting frame, and 12 is spline,
13 is taping block, and 14 is main shaft,
15 for impacting cover.
The specific embodiment
As shown in Figure 3, Figure 4, the striking structure of the utility model impact type pneumatic wrench comprises main shaft 4, taping block 3, impacts cover 5, impacts frame 1, and an end of main shaft 4 is arranged with taping block 3, and taping block 3 is arranged at and impacts in the frame 1; One end of taping block 3 passes through to impact cover 5 fixedlys connected with impact frame 1, and the other end of taping block 3 is fixedlyed connected with impact frame 1 by spline 2;
Taping block 3 comprises strike body, shank, hits body and shank and is formed in one, and the axial length of shank is greater than the axial length that hits body, and shank is arranged at the outside of hitting body; Hitting the inboard of body matches with an end of main shaft 4;
Impact cover 5 and be provided with the groove that matches with the shank of taping block 3, spline 2 is provided with the groove that matches with an end that hits body; One end of taping block 3 achieves a fixed connection with impacting cover 5 by the shank end, and the other end of taping block 3 achieves a fixed connection by hitting body and spline 2.
One end of main shaft 4 is provided with two taping blocks 3, and as shown in Figure 5, two taping blocks 3 are symmetrical arranged with respect to the pivot of main shaft 4, does not promptly have two hammering of pin and hits structure.
One end of main shaft 4 is symmetrically arranged with two taping blocks 3, and then striking structure has the scope of attack of both sides symmetry, can increase the contact area of main shaft 4 and taping block 3 during strike, thereby can increase impulsive force and strike life-span.
Because impact frame 1, spline 2, impact cover 5 are symmetrical structure, make the work of striking structure more steady, increase the rigidity of whole striking structure, increase the stationarity and the strike life-span of striking structure.
