Anti-deviation drilling equipment for machining motor shell of electric vehicle

Abstract

The invention discloses anti-deviation drilling equipment for electric vehicle motor shell machining, and belongs to the field of motor shell machining. The anti-deviation drilling equipment comprises a drilling table, a connecting part is fixedly mounted on the upper surface of the drilling table, and a first fixing seat is slidably arranged on the face, close to the connecting part, of the drilling table; compared with the prior art, a second rotating rod drives a third rotating rod to rotate through two sets of first synchronous wheels and a first synchronous belt, the third rotating rod drives a reciprocating lead screw to rotate, the reciprocating lead screw drives the second rotating rod to rotate, and the second rotating rod drives the reciprocating lead screw to rotate. The reciprocating screw rod drives the rotating block to descend, the rotating block drives the guide block to descend through the first connecting rod, the guide block drives the drilling machine body to descend through the second connecting rod, and drilling machining of the motor shell is completed in the descending process of the drilling machine body, so that drilling machining of the motor shell is conveniently completed. And therefore, the drilling efficiency of the motor shell is effectively improved.

Description

technical field [0001] The invention relates to the technical field of motor casing processing, in particular to an anti-deviation drilling device for processing electric vehicle motor casings. Background technique [0002] Electric vehicle motor: refers to the drive motor used in electric vehicles. The form varies depending on the environment and frequency of use. Different forms of motors have different characteristics. Electric vehicle motors generally use permanent magnet DC motors. Electric vehicle motors can be divided into brush motors and brushless motors according to the energization form of the motors; according to the mechanical structure of the motor assembly, they are generally divided into "toothed" (the motor has high speed and needs to go through the gear deceleration) and "no gear" (motor torque output without any deceleration) two categories. The anti-deflection drilling equipment in the prior art has the following problems when drilling the electric ve...

AI Technical Summary

Problems solved by technology

[0003] 1. When the anti-deflection drilling equipment in the prior art drills the motor casing of the electric vehicle, the motor casing to be processed is mostly manually clamped. Since the drilling machine is in the working state, the operator is clamping the motor casing. At the same time, there are great potential safety hazards, and at the same time, it is not possible to clamp motor casings of different sizes

[0004] 2. When the anti-deflection drilling equipment in the prior art drills the electric vehicle motor casing, the drilling machine and the fixture cannot complete the rotation and drilling of the motor casing in the state of mutual cooperation, resulting in the drilling efficiency of the motor casing lower

[0005] 3. When the anti-deflection drilling equipment in the prior art is drilling the electric vehicle motor casing, when the drilling machine drills the motor casing, it is necessary to spray the drilling water to the drilling hole of the motor casing. In the anti-deflection drilling equipment in the prior art, the liquid spray pipe is in the state of spraying water for a long time, which leads to a serious waste of water resources. Therefore, we propose an anti-deflection drilling equipment for electric vehicle motor casing processing to solve the above problems
