Embodiment Construction

[0008] The reference signs in the accompanying drawings of the specification include: output gear 1 , first transmission gear 2 , input gear 3 , second transmission gear 4 , limit pin 5 , and rocker 6 .

[0009] Below in conjunction with accompanying drawing and embodiment technical solution of the present invention is described in further detail:

[0010] Such as figure 1 As shown, the reversible tapping mechanism of an embodiment of the present invention includes an input gear 3 , an output gear 1 , a rocker 6 and a first transmission gear 2 and a second transmission gear 4 meshing with each other. The rocker 6 is a fan-shaped structure, and the end of the rocker 6 is hinged with the body. There is an arc-shaped steering groove near the fan-shaped edge of the rocker 6, and a limit stop pin connected to the body with an interference fit is snapped into the steering groove. 5. The first transmission gear 2 and the second transmission gear 4 are located near the fan-shaped ed...

Abstract

The invention discloses a direction changeable type tapping mechanism. The direction changeable type tapping mechanism comprises an input gear, an output gear and a rocking handle gear, wherein the rocking handle gear comprises a rocking handle, a first transmission gear and a second transmission gear, the first transmission gear is meshed with the second transmission gear, the rocking handle is of a fan structure, one end of the rocking handle is hinged to a machine body, an arc-shaped reversing groove is formed in the position close to the fan-shaped edge of the rocking handle, a limiting pin which is fixedly connected with the machine body is clamped in the reversing groove, the first transmission gear and the second transmission gear are located at positions, close to the fan-shaped edge, of the rocking handle and hinged to the rocking handle, and the tooth surfaces of the first transmission gear and the tooth surfaces of the second transmission gear protrude out of the fan-shaped edge of the rocking handle; the input gear is hinged to a machine frame and can be meshed with the first transmission gear or the second transmission gear, and a tapping awl can be driven by the output gear; the input gear is hinged to the machine frame and is meshed with the first transmission gear, and the hinge point of the input gear coincides with the hinge point of the rocking handle. According to the direction changeable type tapping mechanism, tapping and retreating can be achieved without the need of a double-faced motor, and tapping at different depths and tapping in different directions can be achieved.

Description

technical field [0001] The invention relates to a thread processing tool, in particular to a reversible tapping mechanism. Background technique [0002] In the prior art, general-purpose tapping machines are relatively large in size, and double-sided motors are generally used to realize the tapping and withdrawal of 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 out without double-sided motors; it can also realize tapping in different depths and directions. [0004] In order to solve the above-mentioned technical problems, the present invention provides a re...
