Full-automatic drill bit replacing type perforating machine

Abstract

The invention discloses a full-automatic drill bit replacing type perforating machine. The machine comprises a perforating head, a rotating mechanism for driving the perforating head to rotate to perforate, a dismounting mechanism for automatically dismounting a drill bit on the perforating head, and a mounting mechanism for automatically mounting the drill bit on the perforating head, wherein a first servo motor can drive a first synchronous belt wheel and a second synchronous belt wheel during working, and a ball screw can rotate through the transmission of the synchronous belt wheels, and thus the drill bit is driven to lengthways reciprocate; a second servo motor can drive a third synchronous belt wheel and a fourth synchronous belt wheel, and the drill bit is driven to rotate through the transmission of the synchronous belt, thus realizing perforating; a cylinder runs to enable simple, quick and accurate automatic replacing of the drill bit after perforating. The machine is proper in size, simple to assemble, high in assembling performance, and high in transmission torque; the machine is applicable to processing of commonly-used paperboards, plastic, steel plates, workpieces, etc., and the applicable scope is wide; the service life of a cutter can be prolonged; and the production quality and efficiency can be improved.

Description

technical field [0001] The invention relates to the field of automatic drilling equipment, in particular to a fully automatic drilling device for changing drill bits. Background technique [0002] So far, most of the automatic drilling machines have remained at the semi-automatic level, and the function of automatic drill replacement is lacking and imperfect. It is mainly used for drilling a single small part, and the drill is usually not replaced until the drill is severely worn and its life is over, or through shutdown. Manually changing the drill bit, this method is dangerous, wastes time and reduces production efficiency. [0003] There are also punchers for automatically changing the drill bit in the existing drill bit punching machine device, but the following problems also exist in this kind of drill bit punching machine device: [0004] 1. It is necessary to replace the drill bit by workers after drilling, and the drill bit cannot be replaced automatically. Full aut...

AI Technical Summary

Problems solved by technology

[0004] 1. It is necessary to replace the drill bit by workers after drilling, and the drill bit cannot be replaced automatically. Full automation is not realized, which intensifies the wear of the drill bit and reduces the service life of the drill bit, and also greatly wastes human resources;

[0005] 2. The accuracy of feeding and drilling is low, and precision machining cannot be performed;

[0006] 3. It can automatically replace the drill bit, but the automatic drill bit replacement device is large in size, complex in structure, difficult to assemble, and high in cost;

[0007] 4. The precise control of electronic full automation has not been realized, and the range of processing materials is narrow
