The utility model discloses a cylinder assembly through the adjustment cylinder body with strike between the cover, connection structure between cylinder body and the chuck, the cylinder assembly that length is more traditional is shorter, passes through the steel ball joint moreover, the dismouting maintains that the vulnerable part is more convenient, life is longer, in addition, improve the block stamp through the aperture of increase piston hole and to the hammering dynamics of drill bushing subassembly, improved work efficiency greatly.
Description
Technical field
This utility model relates to a kind of air cylinder of electric hammer assembly。
Background technology
Impact within electric hammer, impact sleeve etc. are extremely flimsy parts, at present, commercially available electric hammer is after consumable accessory damages, owing to the bonding strength between parts and precision are all bigger, needing special maintenance store to carry out the replacing of consumable accessory, also need to all unload the accessories such as the jump ring being attached thereto, bearing during replacing, process is quite loaded down with trivial details, and often change the service life easily reducing accessory, increase maintenance cost。Additionally, electric hammer is in use, the hammering dynamics of block stamp is big not, and work efficiency can not get a desired effect。
Utility model content
It is easy to maintenance that technical problem to be solved in the utility model is to provide a kind of dismounting, and long service life has the air cylinder of electric hammer assembly of bigger hammering dynamics。
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
Air cylinder of electric hammer assembly, including cylinder body, the front portion of cylinder body has drill bushing hole, rear portion has the piston hole connected with drill bushing hole, the first step that cylinder body is anterior has a steel ball hole I connected with drill bushing hole, the outer wall of the first step being positioned at steel ball hole I front end is equipped with multiple blind hole I, drill bushing is provided with drill bush component in hole, drill bush component includes impact sleeve, the outside of impact sleeve is provided with an annular groove, before impact sleeve being divided into by this annular groove, rear two parts, the front portion of impact sleeve is equipped with blind hole II, blind hole II is by steel ball and steel ball hole I clamping, the rear portion of impact sleeve is equipped with steel ball hole II, impact it is provided with in impact sleeve, the side impacting son is provided with stopper slot, stopper slot is by steel ball and steel ball hole II activity clamping；The rear portion of cylinder body has multiple pore connected with piston hole and a deep gouge, is provided with piston in piston hole, and one end of piston is provided with block stamp, and the other end is provided with connecting rod。
The aperture of described piston hole is more than the aperture in drill bushing hole。
Described blind hole I is 4。
Compared with prior art, the utility model has the advantages that: cylinder assembly of the present utility model is by adjusting the attachment structure between cylinder body and impact sleeve, between cylinder body and chuck, the cylinder assembly that length is more traditional is shorter, and by steel ball clamping, dismounting safeguards that consumable accessory is convenient, longer service life；Additionally, improve the block stamp hammering dynamics to drill bush component by increasing the aperture of piston hole, substantially increase work efficiency。
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail。
Fig. 1 is structural representation of the present utility model。
Wherein, 1, cylinder body, 2, drill bushing hole, 3, first step, 31, blind hole I, 32, steel ball hole I, 4, steel ball, 5, piston hole, 51, pore, 52, deep gouge, 6, impact sleeve, 61, blind hole II, 62, annular groove, 63, steel ball hole II, 7, impact son, 71, stopper slot, 8, block stamp, 9, piston, 10, connecting rod。
Detailed description of the invention:
As shown in Figure 1, air cylinder of electric hammer assembly, including cylinder body 1, the front portion of cylinder body 1 has drill bushing hole 2, rear portion has the piston hole 5 connected with drill bushing hole 2, having a steel ball hole I32 connected with drill bushing hole 2 on the first step 3 of cylinder body 1 front portion, the outer wall of the first step 3 being positioned at steel ball hole I32 front end is equipped with multiple blind hole I31, and the best is 4；It is provided with drill bush component in drill bushing hole 2, drill bush component includes impact sleeve 6, the outside of impact sleeve 6 is provided with an annular groove 62, it is divided into forward and backward two parts, the front portion of impact sleeve 6 to be equipped with blind hole II61, blind hole II61 by steel ball 4 and steel ball hole I32 clamping impact sleeve 6 by this annular groove 62, the rear portion of impact sleeve 6 is equipped with steel ball hole II63, being provided with impact 7 in impact sleeve 6, the side impacting son 7 is provided with stopper slot 71, and stopper slot 71 is by steel ball 4 and steel ball hole II63 activity clamping；The rear portion of cylinder body 1 has multiple pore 51 connected with piston hole 5 and a deep gouge 52, is provided with piston 9 in piston hole 5, and one end of piston 9 is provided with block stamp 8, and the other end is provided with connecting rod 10。
Cylinder assembly of the present utility model adopts the mode that steel ball 4 connects to be connected with outside chuck and its internal impact sleeve 6, the first step of the more traditional cylinder assembly of length of cylinder body 1 first step 3 is longer, but the length of impact sleeve 6 is shorter, the cylinder assembly that the entire length of cylinder assembly is more traditional is also shorter, dismounting safeguards that consumable accessory is convenient, improves the service life of electric hammer；The aperture of piston hole 5, more than the aperture in drill bushing hole 2, is improved the block stamp hammering dynamics to drill bush component by increasing the aperture of piston hole, is substantially increased work efficiency。
