[0013] The technical effects that can be achieved by the technical means of this utility model are as follows:

[0014] (1) In this utility model, by setting a positioning component, the first motor drives the threaded rod to rotate, causing the sliding block to slide on the inner wall of the groove, which in turn drives the punching needle assembly to move along the front and back direction of the device.

[0025] A preferred embodiment of the punching and drilling device for machining mechanical parts provided by this utility model is, for example... Figures 1 to 4 The diagram shows a punching and drilling device for machining mechanical parts, comprising a support platform 1. Positioning components 3 are fixedly mounted on both sides of the top of the support platform 1. A sliding groove 5 is fixedly mounted inside the positioning component 3 and is fixedly connected to the top of the support platform 1. Clamping mechanisms 2 are respectively provided at the front and rear of the top of the support platform 1. A working area 6 is fixedly connected to the middle of the top of the support platform 1. Several mesh holes 7 are provided through the working area 6. A punching mechanism 4 is fixedly mounted between the two positioning components 3. The mesh holes 7 in the middle of the top of the working area 6 penetrate the interior of the support platform 1, facilitating the falling of punched and drilled powder through the mesh holes 7 into corresponding collection containers below the support platform 1.

[0026] In this embodiment, the punching mechanism 4 includes a first U-shaped block 401. A rotary cylinder 410 is rotatably connected to one side of the inner wall of the first U-shaped block 401. A connecting block 402 is fixedly connected to one side of the rotary cylinder 410. A rotating component 403 is rotatably connected to one end of the connecting block 402 away from the rotary cylinder 410. The rotating component 403 is fixedly connected to the other side of the inner wall of the first U-shaped block 401. A second U-shaped block 404 is fixedly connected to the bottom end of the connecting block 402. A rotating block 405 is rotatably connected between the inner walls of the second U-shaped block 404. A second motor 409 is fixedly connected to one side of the second U-shaped block 404. The driving end of the second motor 409 passes through one side of the second U-shaped block 404 and is fixedly connected to the rotating block 405. A punching needle assembly 408 is fixedly provided at the bottom end of the rotating block 405. A disc 407 is fixedly sleeved on the outer wall of the punching needle assembly 408. A nozzle 406 is provided through and communicates with one side of the disc 407.

[0027] Through the above scheme, the rotary cylinder 410 is activated, causing it to rotate relative to the first U-shaped block 401, which in turn drives the connecting block 402 to rotate. The rotating component 403 is fixed to the inner wall of the first U-shaped block 401, providing support and joint rotation. The second motor 409 is activated, causing the rotating block 405 to rotate between the inner walls of the second U-shaped block 404. The rotary cylinder 410 and the second motor 409 work together to further improve the other two rotational degrees of freedom of the punching needle assembly 408, and further improve the positioning accuracy of the punching needle assembly 408. After positioning is completed, the punching needle assembly 408 is activated, causing the punching head at its bottom to punch holes in the part. During the punching process, the nozzle 406 is used to connect to the external coolant and spray the coolant onto the punching head at the bottom of the punching needle assembly 408 to prevent the punching head from generating high temperatures due to excessive rotation speed during punching, which could damage the punching needle assembly 408.

[0028] In this embodiment, the positioning component 3 includes a first motor 301. The driving end of the first motor 301 is rotatably connected to a positioning block 302. The driving end of the first motor 301 is fixedly connected to a threaded rod 307. The end of the threaded rod 307 away from the first motor 301 is rotatably connected to the positioning block 302 away from the first motor 301. A sliding block 306 is threadedly connected to the outer wall of the threaded rod 307. The sliding block 306 is slidably connected to the inner wall of the slide groove 5. A second electric push rod 305 is fixedly connected to the top of the sliding block 306. A support plate 303 is fixedly connected to the top of the second electric push rod 305. A cylinder 304 is fixedly provided at the top of the support plate 303.

[0029] The above scheme starts the first motor 301, which drives the threaded rod 307 to rotate, thereby causing the sliding block 306 to slide on the inner wall of the slide groove 5, which in turn drives the punching needle assembly 408 to move in the front-back direction of the device. The cylinder 304 is started, and the telescopic rods of the two cylinders 304 work together to drive the punching needle assembly 408 to move in the direction of both sides of the device. Finally, the second electric push rod 305 is started to drive the punching needle assembly 408 to move up and down in the vertical direction. The three actions work together to provide the punching needle assembly 408 with three degrees of freedom of movement.

[0030] In this embodiment, the clamping mechanism 2 includes a through groove 203, which is opened at the top of the support platform 1. Two lower positioning protrusions 206 are fixedly connected to the bottom of the through groove 203. A lower roller 205 is rotatably connected between the two lower positioning protrusions 206. A first electric push rod 207 is fixedly connected to the top of the lower roller 205. An upper roller 204 is fixedly connected to the top of the first electric push rod 207. Upper positioning protrusions 208 are rotatably connected to both ends of the upper roller 204. A clamping plate 201 is fixedly connected to the top of the upper positioning protrusions 208. A rotating shaft 209 is rotatably connected to the lower inner wall of the clamping plate 201. The rotating shaft 209 is fixedly connected to the inner wall of the through groove 203. A soft pad 202 is fixedly connected to the top of the clamping plate 201.

[0031] By using the above method, the first electric actuator 207 is activated, and the extension rod of the first electric actuator 207 is shortened to drive the clamping plate 201 to rotate around the pivot 209, so that the soft pad 202 clamps and fixes the part to be processed, thereby improving the accuracy and stability of drilling.

[0032] Working principle: When operating and using this utility model, as follows... Figures 1 to 4 As shown, the part to be processed is placed at the top of the work area 6, and then a positioning operation is performed: the first electric actuator 207 is activated, and the extension rod of the first electric actuator 207 is shortened to drive the clamping plate 201 to rotate around the pivot 209, so that the soft pad 202 clamps and fixes the part to be processed, improving the accuracy and stability of drilling. After clamping, the first motor 301 is activated to drive the threaded rod 307 to rotate, so that the sliding block 306 slides on the inner wall of the slide groove 5, driving the drilling needle assembly 408 to move in the front and back direction of the device. The cylinder 304 is activated, and the extension rods of the two cylinders 304 work together to drive the drilling needle assembly 408 to move in the direction of both sides of the device. Finally, the second electric actuator 305 is activated to drive the drilling needle assembly 408 to move up and down in the vertical direction. The three work together to provide three degrees of freedom for the drilling needle assembly 408. Then the rotary cylinder 410 is activated to rotate relative to the first U-shaped block 401, driving the connecting block 402 to rotate. Part 403 is fixed to the inner wall of the first U-shaped block 401, serving as support and coordinating rotation. The second motor 409 is started, driving the rotating block 405 to rotate between the inner walls of the second U-shaped block 404. The rotary cylinder 410 and the second motor 409 work together to further improve the other two rotational degrees of freedom of the punching needle assembly 408, and further improve the positioning accuracy of the punching needle assembly 408. After positioning is completed, the punching needle assembly 408 is started, so that the punching head at its bottom punches and punches the part. During the punching process, the nozzle 406 is used to connect to the external coolant and spray the coolant onto the punching head at the bottom of the punching needle assembly 408 to prevent the punching head from generating high temperature due to excessive rotation speed during punching, which could damage the punching needle assembly 408. After the punching is completed, the clamping mechanism 2 is released from the mechanical part, and then the punched mechanical part is taken out. The dust generated during the punching process is cleaned up and falls through the mesh 7 into the corresponding collection container below the support platform 1.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed.
