The invention discloses a speed-adjustable reciprocating impact electric hammer which comprises a motor, a first cylinder, a second cylinder and a mounting shell, wherein a reciprocating mobile body is arranged in the first cylinder; a cam positioned in the reciprocating mobile body is arranged at the tail end of a spindle of the motor; a rotary table is arranged at the front end of the reciprocating mobile body; a gear shaft extending into the second cylinder is arranged at the front end of the rotary table; a gearbox is arranged in the mounting shell; a first gear is arranged on the spindle of the motor; a second gear meshed with the first gear is arranged at the input end of the gearbox; and a third gear meshed with the gear shaft is arranged at the output end of the gearbox. The speed-adjustable reciprocating impact electric hammer disclosed by the invention has the advantages that when the spindle of the motor rotates, the cam is driven by the spindle of the motor to rotate, so that the reciprocating mobile body can move back and forth under the assistance of a reset spring, the gear shaft can be driven by the spindle of the motor through the gearbox, and the rotational speed adjustment convenience can be improved.
Description
technical field [0001] The invention relates to the field of electric hammers, in particular to a speed-regulating reciprocating impact electric hammer. Background technique [0002] The electric hammer belongs to the category of electric drills. It is mainly used to make holes in concrete, floors, brick walls and stones. There are also multi-functional electric hammers, which can be adjusted to the appropriate position and can be used instead of ordinary electric drills or electric picks with appropriate drill bits. . [0003] Since the drill bit of the electric hammer also produces rapid reciprocating motion (frequent impact) along the direction of the electric drill rod while rotating, it can quickly drill holes in materials such as brittle cement concrete and stone, but after the reciprocating frequency is determined , but the speed is difficult to adjust and needs to be improved. Contents of the invention [0004] The technical problem mainly solved by the present i...
