Abstract

The invention discloses a method for mounting a multifunctional electric hammer. The method comprises the following mounting steps in sequence: a, mounting a bearing: mounting a bearing I on a step at the head end of an integral gear box, and mounting a clamp spring I into a clamp spring groove I of the integral gear box; b, mounting an eccentric shaft assembly: mounting the eccentric shaft assembly into a bearing chamber inside the integral gear box, and mounting a piston pin on an eccentric shaft in the eccentric shaft assembly inside the integral gear box from an opening of the integral gear box; C, mounting an air cylinder assembly: mounting the air cylinder assembly on the bearing I from the opening of the integral gear box, clamping a clamp spring II into a clamp spring groove II on the tail end opening of the integral gear box, and tightening an oil sealing cover to the port of the integral gear box; D, mounting a motor assembly: covering the bottom of the integral gear box with a middle cover, and arranging the motor assembly below the middle cover; e, mounting a handle and an oil cover. The method has the beneficial effects of simple mounting method, higher strength, reduction of the noise, longer service life and high stability.

Description

technical field [0001] The invention relates to a method for installing a multifunctional electric hammer. Background technique [0002] The electric hammer uses the movement of the piston, and the compressed gas impacts the drill bit. It does not require much effort by the hand, and can open holes in hard materials such as concrete, bricks, and stones. [0003] The electric hammer is based on the electric drill, adding a piston driven by a motor with a crankshaft and connecting rod, and reciprocatingly compresses the air in a cylinder, so that the air pressure in the cylinder changes periodically, and the changing air pressure drives the hammer in the cylinder to reciprocate Hit the top of the drill bit, hence the name electric hammer. [0004] However, the installation of the existing electric hammer is relatively complicated, which greatly reduces the work efficiency. At the same time, the installation is not firm during the installation process, and it is prone to loose...
