At present, the impact hammer, also known as the crushing hammer, is usually large and medium-sized, which must be installed on the excavator for auxiliary application, while the small and medium-sized crushing hammer is often called impact hammer, which is carried out according to the manual service. At present, the impact hammer is usually pneumatic, and its current pneumatic impact hammer structure is more complex, and its impact force is small, crushing force is poor.

The purpose of this innovation is to show the impact hammer of hydraulic press with simple structure and easy to use, stable hydraulic pressure, large impact force and strong crushing capacity,

This paper introduces a kind of hydraulic impact hammer with simple structure, including a cover. The upper, lower, left and right sides of the cover are respectively fixed and fixed. The upper bearing end cover is fixed and connected with an oil motor. The oil motor of the hydraulic impact hammer manufacturer has a coupling according to the fixed fixed fixed connection of the coupling, and the lower part of the coupling is fixed over the upper bearing end cover, and the positive bevel gear is connected, The impact hammer connecting seat is inserted into the cover shell at the lower side of the positive bevel gear, and the impact hammer connecting seat is against the lower bearing end cover. A vertical connecting column is formed under the impact hammer connecting seat. The connecting column is inserted into the lower bearing end cover and the lower inner hole of the lower bearing end cover is exposed. The rectangular frame slot hole surrounding the inner hole of the impact hammer connecting seat is formed above the impact hammer connecting seat On the side of the driven gear which is not connected with the bevel gear, there are two supporting holes on the side of the driven gear which are not connected with the driven gear; A ring-shaped concave platform is formed on the outside of the inner hole of the impact hammer connecting seat, and a pressure spring is inserted in the concave platform. One side of the pressure spring is pressed against the bottom edge of the concave platform, and the other end is pressed against the upper bearing end cover.

A damping rubber cushion block is arranged in the middle of the impact hammer connecting seat and the lower bearing end cover. The upper and lower parts of the damping rubber cushion block are respectively against the impact hammer connecting seat and the lower bearing end cover. The outer surface of the upper surface of the damping rubber cushion block is against a snap ring, and the snap ring is clamped on the cover shell.

The lower bearing end cover is T-shaped, the central and southern part of the lower bearing end cover is formed with a management center through hole, the connecting column of the impact hammer connecting seat is inserted into the management center through hole of the lower bearing end cover, the vertical guiding groove is formed on the connecting column, the guiding groove body is inserted with the guiding block, and the guiding block is fixed on the inner cavity of the through hole of the management center of the bearing end cover.
