Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a tapping device for steering gear rack, includes the device body, the device body includes workstation 1, workstation 1 is fixed with through supporting seat 3 and is used for attacking tooth mechanism 4 of tooth to rack 2, attacks tooth mechanism 4 and includes the pneumatic cylinder, pneumatic cylinder lower extreme fixed motor, the fixed tooth drill bit of attacking of motor output shaft, through pneumatic cylinder work extension, the drive motor moves down, motor circular telegram work drives attacks tooth drill bit and rotates and attack tooth to rack 2, be prior art above, be different from prior art and be:

the tapping mechanism 4 is vertically sleeved with a chip collecting cover 6 in a sliding mode, one side of the chip collecting cover 6 is fixedly provided with a hose 11 in a penetrating mode, the end portion of the hose 11 is fixedly connected with a negative pressure hard pipe 10, the negative pressure hard pipe 10 is fixedly connected with the supporting seat 3, and the lower end of the negative pressure hard pipe 10 is rotatably connected with a brush 7 used for cleaning the upper surface of the rack 2; an operator externally connects a dust suction pump to the left end of the negative pressure hard pipe 10 (the dust suction pump is prior art, which is not described herein too much, and the principle can refer to a dust collector). During tapping, the brush 7 is manually rotated to one side, so that the brush 7 is far away from the lower part of the chip collecting cover 6, then the tapping mechanism 4 works to move downwards to tap the rack 2, the chip collecting cover 5 is moved downwards to cover the tapping position on the rack 2, so that the hose 11 is bent and deformed, chips generated during tapping on the upper surface of the rack 2 are sucked into the hose 11 through the chip collecting cover 6 by the working of the dust suction pump, and then the negative pressure hard pipe 10 is sucked into the negative pressure hard pipe 10 and finally discharged through the dust suction pump, so that the chips can be rapidly removed from the surface of the rack 2, after the tapping mechanism 4 moves upwards to separate from the rack 2, the chip collecting cover 6 is moved upwards to separate from the upper surface of the rack 2, at this time, the brush 7 can be manually rotated to move on the rack 2, and further clean the residual chips and dust which is not sucked from the upper surface of the rack 2.
