Electric hammer cylinder assembly

Abstract

The invention discloses an electric hammer cylinder assembly, which includes a cylinder body. The front and rear parts of the cylinder body are respectively provided with a drill sleeve hole and a piston hole. A steel ball communicating with the drill sleeve hole is opened on the first step at the front of the cylinder body. Hole I, the outer wall ring of the first step located at the front end of the steel ball hole I is provided with a plurality of blind holes I, a drill sleeve assembly is provided in the drill sleeve hole, the drill sleeve assembly includes an impact sleeve, and the front ring of the impact sleeve is provided with a blind hole. Hole II and blind hole II are clamped with steel ball hole I through a steel ball, an impactor is arranged in the impact sleeve, a piston is arranged in the piston hole, a hammer is arranged at one end of the piston, and a connecting rod is arranged at the other end. The cylinder assembly of the present invention is shorter than the traditional cylinder assembly by adjusting the connection structure between the cylinder body and the impact sleeve, and between the cylinder body and the chuck, and is connected by steel balls to disassemble and maintain vulnerable parts It is more convenient and has a longer service life; in addition, by increasing the diameter of the piston hole, the impact force of the hammer on the drill sleeve assembly is increased, which greatly improves the working efficiency.

Description

technical field [0001] The invention relates to an electric hammer cylinder assembly. Background technique [0002] The impactor and impact sleeve inside the electric hammer are extremely vulnerable parts. At present, after the vulnerable parts of the commercially available electric hammer are damaged, due to the high connection strength and precision between the parts, it is necessary to go to a special repair shop. To replace the wearing parts, it is necessary to remove all the auxiliary parts such as the circlips and bearings connected with it. The process is quite cumbersome, and frequent replacement will easily reduce the service life of the auxiliary parts and increase the maintenance cost. In addition, when the electric hammer is in use, the impact force of the impact hammer is not strong enough, and the work efficiency cannot achieve the desired effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ...

To replace the wearing parts, it is necessary to remove all the auxiliary parts such as the circlips and bearings connected to it. The process is quite cumbersome, and frequent replacement will easily reduce the service life of the auxiliary parts and increase the maintenance cost.

In addition, when the electric hammer is in use, the impact force of the hammer is not strong enough, and the work efficiency cannot achieve the expected effect.
