Abstract

The utility model relates to a double hammer impact structure, in particular to a double hammer impact structure with strengthened intensity of the double beating facet by an iron shaft. The strengthened double hammer impact structure comprises an iron shaft, an impact barrel, a beat pin, beat blocks, and a beat block pad, wherein a beat block pad is arranged between the two beat blocks, under the same block and beating area, it enhances the supporting effect of the iron shaft beating area through enhancing the length, a sunk desk is formed in the impact barrel, the beating facet can be sunk into the sunk desk, enlarging the area of beating facet can enhance the supporting effect. By the above two ways, the service life of the iron shaft is prolonged.

Description

Reinforced pair of hammer impact structure

Technical field

The utility model relates to a kind of pair of hammer impact structure, particularly a kind of reinforced pair of hammer impact structure that is used for the two scope of attack intensity of reinforcement iron axle of pneumatic impact spanner.

Background technology

The operation principle of pneumatic impact spanner is that compressed air enters eccentric cylinder by speed adjusting gear, promotes the blade rotation, produces high-octane alternating shock load of moment thereby drive rotor by striking structure.Two taping blocks of impact structure also break away from iron axle scope of attack moment impact under the effect of centripetal force, when contacting with iron axle two scopes of attack, taping block has very strong impulsive force, traditional double hammer impact structure iron axle scope of attack width is narrower, therefore, in use for some time, cause the wearing and tearing of iron axle easily or burst apart because iron axle shock surface bears high-intensity impulsive force for a long time.

Summary of the invention

The purpose of this utility model is a kind of reinforced pair of hammer impact structure that is used for the two scope of attack intensity of reinforcement iron axle of pneumatic impact spanner of design.

Reinforced pair of hammer impact structure described in the utility model by the iron axle, impact tube, hit pin, two taping blocks and taping block pad form; Two taping blocks and taping block pad are through on the iron axle, and the taping block pad can make iron axle scope of attack length increase between two taping blocks like this, strengthens its supporting role; Impact tube with iron axle, two taping blocks and taping block pad cover therein, impact in the tube being processed with heavy stand, iron axle lower end embeds in the heavy stand, iron axle scope of attack length is increased, and strengthen its supporting role.

Good effect of the present utility model is: the utility model is compared with traditional two hammer impact structures have been increased the impact block pad and be processed with heavy stand in impacting tube; Taping block pad of assembling between two taping blocks, make under the strike area of same taping block, strengthen iron axle scope of attack length and played the supporting role of strengthening the iron axle scope of attack, impacting the inner processing of tube heavy stand, the scope of attack can be absorbed in the heavy stand under the iron axle, increase the width of the scope of attack and play the reinforcement supporting role, the iron axle scope of attack is by the reinforcement of above two aspects, and the service life of having improved the iron axle greatly.

The specific embodiment

As shown in Figure 1 and Figure 2, reinforced pair of hammer impact structure described in the utility model is made up of iron axle 1, impact tube 2, strike pin 4, taping block 5 and taping block pad 3; Two taping blocks 5 and taping block pad 3 are through on the iron axle 1, and taping block pad 3 can make the iron axle scope of attack 6 length increase between two taping blocks like this, strengthens its supporting role; Impact tube 2 with iron axle 1, taping block 5 and taping block pad 3 covers therein, impact in the tube 2 being processed with heavy stand 7, iron axle 1 lower end embeds in the heavy stand 7, iron axle scope of attack length is increased, and strengthen its supporting role.

Fig. 3, Figure 4 shows that the schematic diagram and the explosive view of traditional double hammer impact structure as can be seen from the figure, between two taping blocks, do not have the taping block pad, and impact in the tube and also do not process heavy stand.

Claims

1, a kind of reinforced pair of hammer impact structure is characterized in that: reinforced pair of hammer impact structure described in the utility model by the iron axle, impact tube, hit pin, two taping blocks and taping block pad form; Two taping blocks and taping block pad are through on the iron axle, and the taping block pad is between two taping blocks; Impact tube with iron axle, taping block and taping block pad cover therein, impact in the tube being processed with heavy stand, iron axle lower end embeds in the heavy stand.
