Abstract
The utility model discloses an air cylinder, including the cylinder body, the cylinder body divide into front portion and rear portion, and anterior opening has the drill bushing hole, and the piston hole that has with drill bushing hole intercommunication is opened at the rear portion, open on the anterior first step have one with the steel ball hole of drill bushing hole intercommunication, the outer wall ring that is located the first step of steel ball hole front end is equipped with a plurality of blind holes, the rear portion is opened the gas pocket that has a plurality of and piston hole intercommunication and one is sunk grooves. The utility model discloses an air cylinder has increased the length of first step to direct steel ball hole and the blind hole of setting up on first step realizes through the blind hole that the direct joint between cylinder body and the chuck is fixed, and easy dismounting also changes in the maintenance and the change of vulnerable part, simultaneously, the aperture of piston hole is greater than the aperture in drill bushing hole, increases the impact force to the drill bushing.
Description
Technical field
This utility model relates to a kind of cylinder.
Background technology
Impact of electric hammer cylinder interior, impact sleeve etc. are the most flimsy parts, existing electric hammer uses chuck to be fastenedly connected with cylinder front portion, special maintenance store is needed to carry out the replacing of consumable accessory, also need to during replacing all unload the accessories such as the jump ring being attached thereto, bearing, process is the most loaded down with trivial details, and often change the service life easily reducing accessory, increase maintenance cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of consumable accessory that can quickly realize and safeguards the cylinder changed.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of cylinder, including cylinder body, cylinder body is divided into front and rear, front portion has drill bushing hole, rear portion has the piston hole connected with drill bushing hole, having a steel ball hole connected with drill bushing hole on anterior first step, the outer wall of the first step being positioned at steel ball hole front end is equipped with multiple blind hole, and rear portion has multiple pore connected with piston hole and a deep gouge.
The aperture of described piston hole is more than the aperture in drill bushing hole.
Described blind hole is 4.
Compared with prior art, the utility model has the advantages that: cylinder of the present utility model adds the length of first step, and directly steel ball hole and blind hole are set on first step, directly connecting and fixing between cylinder body and chuck is realized by blind hole, easy accessibility, is also easier to maintenance and the replacing of consumable accessory；Meanwhile, the aperture of piston hole, more than the aperture in drill bushing hole, increases the impulsive force to drill bushing.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein, 1, cylinder body, 2, anterior, 21, drill bushing hole, 22, first step, 3, rear portion, 31, piston hole, 4, blind hole, 5, steel ball hole, 6, pore, 7, deep gouge.
Detailed description of the invention:
As shown in Figure 1, a kind of cylinder, including cylinder body 1, cylinder body 1 is divided into front portion 2 and rear portion 3, and anterior 2 have drill bushing hole 21, and rear portion 3 has the piston hole 31 connected with drill bushing hole 21, the aperture in drill bushing hole 21 is less than the aperture of piston hole 31, having a steel ball hole 5 connected with drill bushing hole 21 on the first step 22 of anterior 2, the outer wall of the first step 22 being positioned at steel ball hole 5 front end is equipped with 4 blind holes 4, and rear portion 3 has multiple pore 6 connected with piston hole 31 and a deep gouge 7.
In this utility model, in order to make steel ball hole 5 and blind hole 4 be provided entirely on first step 22, the cylinder that the length of first step 22 is more traditional is longer；Directly connecting and fixing between cylinder body 1 and electric hammer chuck, easy accessibility can be realized by blind hole 4, be also easier to maintenance and the replacing of consumable accessory, it is not necessary to go special maintenance store to safeguard；Meanwhile, the aperture of piston hole 31 is more than the aperture in drill bushing hole 21, and the volume making block stamp and piston is bigger, increases the impulsive force to drill bushing.
Claims (3)
1. a cylinder, including cylinder body, described cylinder body is divided into front and rear, described front portion has drill bushing hole, described rear portion has the piston hole connected with drill bushing hole, it is characterized in that: have a steel ball hole connected with drill bushing hole on the first step of described front portion, the outer wall of the first step being positioned at described steel ball hole front end is equipped with multiple blind hole, and described rear portion has multiple pore connected with piston hole and a deep gouge.
