Abstract
The utility model relates to the field of mechanical technique, especially, in particular to a striking structure which has large torsion, stable striking performance and can be controlled through a clutch and is used on the pneumatic tool. The utility model includes a rotation shaft, a driving hammer, a transmission shaft; one end of the transmission shaft is inserted in the center of the rotation shaft and the other end of the transmission shaft sequentially passes through a spring, a three-claw clutching block and then is fixedly inserted in a rotating block; the rotating block is fixedly connected with the three-claw clutching block and the rotating block is positioned in the cavity of the driving hammer. A triangular groove to hold the three-claw clutching block is provided on the driving hammer. By adopting the structure, the driving hammer and the rotating shaft can be controlled by a clutch and the purpose of saving energy source can be realized. So, the utility model has the advantages of large torsion, stable striking performance; the driving hammer and the rotation shaft can be separated when no striking operation is made, which can reduce the friction of the striking face and is durable.
Description
Technical field:
The utility model relates to field of mechanical technique, but refers in particular to the striking structure that a kind of torsion is big, hit the pneumatic tool of steady clutch.
Background technology:
The general pneumatic tool scope of application is very extensive, and pneumatic tool is to utilize the pneumatic mode that passes in and out gas formation to drive pneumatic tool to do different occupation modes.As a kind of instrument with pneumatic actuation effect, progressive when it is used is conspicuous, yet, when using, reality finds that also there is certain shortcoming in existing air tool striking structure, as shown in Figure 1 a kind of clicks to beat and hits structure, its structure only is made up of rotating shaft 1, hammer 2 and alignment pin 3, hit during strike steadily and the scope of attack little; Structure is hit in double-click hammering and for example shown in Figure 2, and its structure includes two alignment pins 3, rotating shaft 1 and hammer 2, though this structure is hit steadily, vibration is little, the scope of attack is big, its torsion is less; Latch structure is hit in the doubles of Fig. 3 dicyclo striking structure and Fig. 4 for another example, and the pneumatic tool of these two kinds of structures hits steadily, torsion is big and rotating speed is high though adopt.Yet when the air tool striking structure that adopts said structure often all is the structure that adopts turning cylinder 1 to fixedly connected with hammer 2, when it did not hit operation, hammer 2 still with turning cylinder 1 rotation, caused unnecessary waste.
Summary of the invention:
But that the purpose of this utility model is exactly provide at the deficiencies in the prior art part a kind of that can address the above problem, torsion is big, hit the steadily striking structure of the pneumatic tool of clutch.
For achieving the above object, the utility model includes: turning cylinder and hammer, also include the power transmission shaft that an end is plugged in the turning cylinder center, the other end of power transmission shaft fixedly was plugged in the spill spin block after wearing spring, three-jaw clutch block successively, spill spin block is fixedlyed connected with the three-jaw clutch block, and spill spin block is positioned at the cavity of hammer, also forms the triangle groove that holds the three-jaw clutch block on hammer.
Between described spring and three-jaw clutch block, also be provided with lower gasket.
Also be provided with Upper gasket between the cavity in described spill spin block and hammer.
After having adopted said structure, because rotating shaft links to each other with hammer indirectly by the three-jaw clutch block, so, when pneumatic tool not when hitting operation, the three-jaw clutch block is separating with triangle groove on the hammer under the effect of spring force, and like this, turning cylinder rotates and only drives the three-jaw clutch block and dally together, hammer separates with it and stops operating, and reaches the purpose of saving resource.Therefore, the utlity model has: torsion is big, strike is steady, hammer can separate with turning cylinder when not hitting operation, reduces the friction of the scope of attack, durable characteristics.
Description of drawings:
Fig. 1 has now to click to beat to hit the structural upright exploded view;
Fig. 2 is that the structural upright exploded view is hit in existing double-click hammering;
Fig. 3 is existing dicyclo striking structure three-dimensional exploded view;
Fig. 4 is that the latch structure three-dimensional exploded view is hit in existing doubles;
Fig. 5 is the utility model stereochemical structure exploded view.
Specific embodiments:
See shown in the accompanying drawing 5, the utility model includes: turning cylinder 1 and hammer 2, also include the power transmission shaft 3 that an end is plugged in turning cylinder 1 center, the other end of power transmission shaft 3 wore spring 4 successively, three-jaw clutch block 5 backs fixedly are plugged in the spill spin block 6, spill spin block 6 is fixedlyed connected with three-jaw clutch block 5, and spill spin block 6 is positioned at the cavity 21 of hammer 2, also forms the triangle groove 22 that holds three-jaw clutch block 6 on hammer 2.Between described spring 4 and three-jaw clutch block 5, also be provided with lower gasket 8.Also be provided with Upper gasket 7 between the cavity 21 in described spill spin block 6 and hammer 2.
In use, after the energising, turning cylinder 1 rotates, be plugged in the also rotation thereupon of power transmission shaft 3 that turning cylinder 1 center is connected with its key, turning cylinder 3 drives the spill spin block 6 that is fixed on the one end and rotates, because spill spin block 6 is fixedlyed connected with three-jaw clutch block 5, therefore, three-jaw clutch block 5 just rotation gets up, when hitting operation, three-jaw clutch block 5 is entrenched in the triangle groove 22 on the hammer 2 just, and three-jaw clutch block 5 drives hammers 2 rotations and hits operation, when not when hitting operation, three-jaw clutch block 5 is separating with triangle groove 22 on the hammer 2 under the effect of spring 4 elastic force, and like this, turning cylinder 1 rotates and only drives three-jaw clutch block 5 and dally together, hammer 2 separates with it and stops operating, and reaches the purpose of saving resource.Therefore, the utlity model has: torsion is big, strike is steady, hammer can separate with turning cylinder when not hitting operation, reduces the friction of the scope of attack, durable characteristics.
