The device comprises a rack, the rack is fixedly provided with a first motor and further rotationally connected with a workbench, the workbench is provided with a preformed hole, the output shaft of the first motor is fixedly connected with a cam with which a connecting rod is fixedly connected, a connecting block is fixedly connected with the connecting rod, a second motor is fixedly arranged on the connecting block, a drill bit is fixedlyconnected with the output shaft of the second motor, the rack is further fixedly provided with a piston cylinder, a spring is connected between a piston and an inner wall of the piston cylinder, a pawl is further arranged on a piston rod, a ratchet wheel is rotationally connected with the rack, a first gear is coaxially connected with the ratchet wheel, a gear rack is meshed with the first gear,a second gear is meshed with the gear rack, the second gear is coaxially connected with a first bevel gear, and a second bevel gear, which is coaxially connected with the workbench, is meshed with thefirst bevel gear. By adopting the technical scheme, holes can be uniformly drilled in the circumferential direction in a workpiece, and the automobile accessory perforating device is mostly used fordrilling holes in the circumferential direction in the workpiece.

Description

technical field [0001] The invention belongs to the technical field of processing holes on metal products, and in particular relates to a punching device for auto parts. Background technique [0002] During the processing of auto parts, the workpiece needs to be punched according to the function, appearance and weight reduction requirements of the parts. However, the existing devices for punching workpieces have the disadvantages of low work efficiency, uneven punching, and rough holes. [0003] For this reason, Chinese patent CN205888142U discloses a kind of equidistant high-efficiency drilling device for metal plates, including base plate, first guide rod, the left end of the first guide rod is connected with the first gear, and the middle part of the first guide rod is vertically provided with the second Three springs, the bottom of the first guide rod is provided with an electromagnet, the bottom of the third spring is connected with an iron block, the top of the first ...

AI Technical Summary

Problems solved by technology

[0004] However, there are the following problems in the above-mentioned scheme: continuously drilling the workpiece, the drill bit will generate a large amount of heat due to friction, and due to the characteristics of metal thermal expansion and contraction, the drill bit will cause inaccurate drilling size after deformation, which will affect the quality of the workpiece. Reduce the service life of the drill bit; and in the above scheme, only the plate can be drilled, and the workpiece cannot be drilled circumferentially
