Bidirectional drilling device for motor rotating shaft

Abstract

The invention relates to the field of motors, in particular to a bidirectional drilling device for a motor rotating shaft. The device comprises a bottom plate fixed to a rack, a feeding pipe is fixed to the bottom plate, a feeding device is further fixed to the position, at the feeding pipe, of the bottom plate, a plurality of feeding air cylinders are further fixed to the position, at the tail end of the feeding pipe, of the bottom plate, the tail ends of piston rods of the feeding air cylinders are fixed to a sliding table, a plurality of binding belts are further fixed to the sliding table, one end of each binding belt is fixed to the sliding table, the other end of each binding belt penetrates through a positioning groove in the corresponding position of the sliding table and then is fixed to a fixing block, a plurality of fixing air cylinders are further fixed to the sliding table, the tail ends of piston rods of the fixing air cylinders are fixed to the fixing block, positioning blocks are evenly fixed to the binding band, and positioning elastic pieces are fixed to the positions, corresponding to the binding band, of the sliding table. Through the device, the two ends of the rotating shaft can be punched at the same time, the production efficiency of the rotating shaft is greatly improved, and automatic punching operation of the rotating shaft is achieved.

Description

【Technical field】 [0001] The invention relates to the field of motors, in particular to a bidirectional drilling device for a motor shaft. 【Background technique】 [0002] In the process of motor manufacturing, the motor shaft is made by turning. The shaft is preliminarily processed from a bar blank through a lathe, and then counterbore slots are drilled at both ends of the shaft. The counterbore slots at both ends of the shaft are currently being implemented. In the process of processing, first fix one end of the shaft with a clamp, use a drilling machine to drill a hole at the protruding end of the shaft, then loosen the clamp, clamp and fix the other end of the shaft, and then use a drilling machine to drill a hole at the protruding end of the shaft. Drilling, so as to implement the drilling operation on the two ends of the rotating shaft, so the drilling operation at the two ends of the above-mentioned rotating shaft is inefficient and is not suitable for large-scale indu...

[0002] In the process of motor manufacturing, the motor shaft is made by turning. The shaft is preliminarily processed from a bar blank through a lathe, and then counterbore slots are drilled at both ends of the shaft. The counterbore slots at both ends of the shaft are currently being implemented. In the process of processing, first fix one end of the shaft with a clamp, use a drilling machine to drill a hole at the protruding end of the shaft, then loosen the clamp, clamp and fix the other end of the shaft, and then use a drilling machine to drill a hole at the protruding end of the shaft. Drilling, so as to implement the drilling operation on the two ends of the rotating shaft, so the drilling operation at the two ends of the above-mentioned rotating shaft is inefficient and is not suitable for large-scale industrial production. The friction between the shaft and the shaft is not strong enough, it is easy to cause the shaft to rotate with the drill bit, resulting in the problem that the shaft is scratched by the fixture
