Abstract

The invention discloses a bidirectional tapping machine which comprises an input gear, a steering eccentric wheel, a swing arm and an output gear, one end of the input gear is fixedly connected with a belt wheel which is coaxial with the input gear, and the belt wheel is connected with a belt wheel of a motor through an elastic belt. The swing arm is fixedly connected with the steering eccentric wheel, the input gear is hinged between the swing arm and the steering eccentric wheel, and the outer contour of the steering eccentric wheel is hinged to a rack. The swing arm is further hinged to an idle gear which is meshed with the input gear. The output gear can be meshed with the input gear or the idle gear, and the output gear drives a tapping screw. The idle gear, the output gear and the input gear are all divided into left half parts and right half parts, and the contact end faces of the left half parts and the right half parts are all provided with inverted-cone-shaped protrusions and inverted-cone-shaped clamping grooves which are clamped with each other. The bidirectional tapping machine can achieve propelling and retreating of tapping without the need of a two-sided motor, and tapping at different depths in different directions can further be achieved.

Description

technical field [0001] The invention relates to a threaded part, in particular to a two-way tapping machine for processing threaded holes on an air-conditioning panel. Background technique [0002] In the prior art, it is necessary to process threaded holes on the air-conditioning panel so that the air-conditioning panel can be fixed on the air-conditioning casing by bolts. The general-purpose tapping machine has a large volume, and generally uses a double-sided motor to realize the tapping and exiting of the tapping. When the motor rotates forward, the tapping advances; when the motor reverses, the tapping exits. The method of realizing the attacking and withdrawing of the tapping with the positive and negative rotation of the motor is inefficient, poor in reliability, and also greatly shortens the life of the motor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mechanism that can realize tapping in and ou...
