Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 The utility model provides a technical solution: a stainless steel plate punching device, including an electromagnetic base 1, an electromagnet embedded in the bottom of the electromagnetic base 1, a T-shaped slide rail 102 fixedly connected to the electromagnetic base 1, a support frame 2 slidably installed on the T-shaped slide rail 102, a T-shaped slide groove 204 is provided under the support frame 2, the T-shaped slide groove 204 slides with the T-shaped slide rail 102, a dovetail slide groove 201 is provided on the front of the support frame 2, an adjusting connection mechanism 3 is slidably installed in the dovetail slide groove 201, a lower pressure column 4 is fixedly connected to the lower end of the lower pressure column 4 is fixedly connected to a power motor 401, a chuck 402 is fixedly connected to the output end of the power motor 401, a drill bit 403 is clamped in the chuck 402, and a dust cover 5 is covered on the drill bit 403.

[0023] In this embodiment, the device is placed on the stainless steel plate as a whole by means of the electromagnet arranged in the electromagnetic base 1, and the drill bit 403 is roughly aligned with the drilling position, and then the electromagnet is started, and the electromagnetic base 1 can be adsorbed and fixed on the stainless steel plate by magnetic force, thereby fixing the device on the stainless steel plate, and the T-shaped slide rail 102 is slidably matched with the T-shaped slide groove 204, so that the support frame 2 can move left and right to adjust the lateral position of the drill bit 403, and the front and rear position of the drill bit 403 can be adjusted by the adjustment connection mechanism 3, thereby fine-tuning the final drilling position of the drill bit 403, and the power motor 401 is started to drive the chuck 402 to rotate, and the chuck 402 will then drive the drill bit 403 to rotate, and then the adjustment connection mechanism 3 is moved downward, and the adjustment connection mechanism 3 will drive the drill bit 403 downward after transmission through the down-pressing column 4, the power motor 401, and the chuck 402, thereby performing the drilling operation on the stainless steel plate, and the dust cover 5 is put around the drill bit 403 to prevent the debris generated by the drilling from splashing and to protect the operator as much as possible.

[0024] Among them, in order to achieve the purpose of adjusting the position of the support frame 2, this device adopts the following technical solutions: a protective rubber pad 101 is fixedly connected to the bottom of the electromagnetic base 1, and a first threaded adjustment rod 103 is rotatably installed on the top of the electromagnetic base 1 and located behind the T-shaped slide rail 102 through a bearing seat. A first threaded sleeve 205 is fixedly connected to the rear of the support frame 2 near the lower end edge, and the first threaded sleeve 205 is threadedly matched with the first threaded adjustment rod 103. A threaded drive rod 202 is rotatably installed in the dovetail groove 201, and a drive motor 203 is fixedly connected to the upper end of the support frame 2, and the output end of the drive motor 203 is fixedly connected to the threaded drive rod 202.

[0025] The protective rubber pad 101 can replace the electromagnetic base 1 in contact with the stainless steel plate, avoiding direct contact between the electromagnetic base 1 and the stainless steel plate, which may cause the surface of the stainless steel plate to be scratched. At the same time, the protective rubber pad 101 made of rubber can increase the friction between the electromagnetic base 1 and the stainless steel plate, avoiding the electromagnetic base 1 from sliding around. The first threaded adjustment rod 103 is threadedly matched with the first threaded sleeve 205. Rotating the first threaded adjustment rod 103 can drive the first threaded sleeve 205 to move. The movement of the first threaded sleeve 205 will drive the support frame 2 to move, thereby adjusting the position of the support frame 2 laterally. Starting the drive motor 203 can drive the threaded drive rod 202 to rotate.

[0026] The second adjusting screw 304 is fixed on the front of the second connecting rod 302, and the second adjusting screw 304 is fixed on the front of the second connecting rod 302. The second adjusting screw 304 is fixed on the front of the second connecting rod 302, and the second adjusting screw 304 is fixed on the back of the second connecting rod 302. The threaded through hole 306 is formed in the dovetail slider 305, and the threaded through hole 306 is threadedly matched with the threaded driving rod 202. The dust cover 5 is fixed with connecting ears 501 on both sides, and the telescopic connecting rod 502 is fixed on the top of the connecting ear 501. The other end of the telescopic connecting rod 502 is fixed to the bottom of the power motor 401, and a return spring 503 is sleeved on the telescopic connecting rod 502.

[0027] The dovetail slider 305 is slidably matched with the dovetail slide groove 201, so that the adjustment connection mechanism 3 is slid on the front of the support frame 2, and the threaded through hole 306 is threadedly matched with the threaded drive rod 202, so that rotating the threaded drive rod 202 can drive the dovetail slider 305 to move, and the movement of the dovetail slider 305 will drive the adjustment connection mechanism 3 to move as a whole, thereby adjusting the height of the drill bit 403, and the dovetail slider 305 cooperates with the second threaded hole. Rotating the dovetail slider 305 can drive the second connecting column 302 to move, thereby adjusting the position of the first connecting head 301, and then adjusting the position of the drill bit 403 back and forth. The dust cover 5 is connected to the chuck 402 through the telescopic connecting rod 502, and the return spring 503 can provide a certain downward thrust for the dust cover 5, so that the dust cover 5 will always be in contact with the stainless steel plate when the drill bit is drilling.

[0028] The working principle and usage process of the present invention are as follows: when in use, the device needs to be placed on the stainless steel plate that needs to be punched, and then the position of the device is roughly adjusted so that the drill bit 403 is roughly aligned with the punching position, and then the electromagnet is started, and the electromagnetic base 1 can be adsorbed and fixed on the stainless steel plate by magnetic force, thereby fixing the device on the stainless steel plate, and the first threaded adjustment rod 103 is rotated to drive the drill bit 403 to move left and right, and the second threaded adjustment rod 304 is rotated to drive the drill bit 403 to move back and forth, and then the drill bit 403 is finally fine-tuned so that the drill bit 403 is accurately aligned with the punching position, and then the drive motor 203 is started to drive the threaded drive rod 202 to rotate. The rotation of the threaded drive rod 202 will drive the adjustment connecting mechanism 3 to move downward, and the downward movement of the adjustment connecting mechanism 3 will drive the drill bit 403 to move downward, and the power motor 401 is started to drive the drill bit 403 to rotate at high speed. The drill bit 403 that rotates at high speed and moves downward can perform a drilling operation on the stainless steel plate.
