[0002] Currently, such as Figure 1 The electric vehicle controller 6 shown has multiple connecting screw holes 61 drilled on its housing surface. Existing technology uses CNC machine tools for drilling. By clamping the electric vehicle controller onto the CNC machine tool, automatic drilling can be achieved, which is relatively convenient.

[0003] However, the existing fixtures for clamping electric vehicle controllers are quite complex to use. They require manual precision placement of the electric vehicle controllers to complete the clamping process. In addition, manual removal of debris from the fixtures is also required before the electric vehicle controllers can be placed, resulting in low production efficiency. Utility Model Content

Detailed Implementation

[0020] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0021] This application discloses a drilling device for opening holes in the surface of an electric vehicle controller housing, referring to... Figure 2-4 The system includes a CNC drilling machine 1. A fixture is mounted on the frame of the CNC drilling machine 1. A waste collection box 11 is located at the bottom of the frame of the CNC drilling machine 1. The fixture is located on top of the waste collection box 11. The fixture includes a vertical rod, a support platform 2, and a side positioning and clamping mechanism. The vertical rod is vertically fixed inside the frame of the CNC drilling machine 1. The support platform 2 is horizontally fixed to the end of the vertical rod. A placement slot 21 is provided in the middle of the support platform 2 for supporting the electric vehicle controller housing. The side positioning and clamping mechanism includes positioning and clamping components 3 symmetrically arranged on both sides of the vertical rod. The positioning and clamping components 3 on both sides can clamp and press the electric vehicle controller housing onto the support platform 2. The positioning and clamping components 3 include a bracket 31, a cylinder 32, and a clamping element 33. The bracket 31 is fixed... The cylinder 32 is fixed on the support 31 within the frame of the CNC drilling machine tool 1. The clamping member 33 is fixed on the piston rod end of the cylinder 32. The clamping member 33 includes a connecting block 331, a push block 332, a spring 333, and a pressing block 334. The connecting block 331 is fixed on the piston rod end of the cylinder 32. A hole is opened on the side of the connecting block 331. The spring 333 is fixed in the hole. The push block 332 is fixed on the end of the spring 333. The push block 332 can fit against the connecting block 331. The pressing block 334 is fixed on the side of the connecting block 331. The distance between the pressing block 334 and the support platform 2 is the same as the wall thickness of the electric vehicle controller housing. A support sleeve is also fixed on the support 31. The piston rod of the cylinder 32 is movably arranged in the support sleeve.

[0022] An air pipe 4 is also provided in the positioning and clamping assembly 3 on one side. An air nozzle 5 is installed on the air pipe 4. The air pipe 4 is fixed on the bracket 31, and the air nozzle 5 is set towards the electric vehicle controller housing.

[0023] Reference Figure 3 In order to provide guidance and support for the push block 332, a telescopic sleeve is provided inside the spring 333. One end of the telescopic sleeve is fixedly connected to the end hole, the side of the push block 332 is fixed on the telescopic sleeve, and the spring 333 is sleeved on the surface of the telescopic sleeve.

[0024] Reference Figure 3 In order to facilitate the pressing of the lower block 334 against the electric vehicle controller housing, the bottom of the lower block 334 away from the connecting block 331 is chamfered.

[0025] The implementation principle of the drilling equipment for opening holes on the surface of an electric vehicle controller housing according to an embodiment of this application is as follows:

[0026] In use, the operator only needs to place the electric vehicle controller housing in the placement slot 21 of the support platform 2. The cylinders 32 in the positioning clamping components 3 on both sides extend and push the clamping parts 33 to move towards the electric vehicle controller housing. The push block 332 in the clamping parts 33 first contacts the electric vehicle controller housing, and can gradually adjust the position of the electric vehicle controller housing until the spring 333 is compressed and the push block 332 fits against the connecting block 331. The electric vehicle controller housing can be centered and clamped on the support platform 2, and the pressing block 334 in the clamping parts 33 can press on the lower side wall of the electric vehicle controller housing, thereby limiting the electric vehicle controller housing in the vertical direction. The entire clamping process can be automated, which greatly reduces the labor intensity of the operator.

[0027] By installing the air nozzle 5, during the drilling process, the air nozzle 5 can blow away the debris generated during drilling inside the electric vehicle controller housing. After drilling is completed, the air nozzle 5 can also blow clean the surface of the support platform 2, eliminating the need for staff to clean. Staff only need to place and remove the electric vehicle controller housing, which greatly improves production efficiency.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
