[0002] Mechanical drilling is the process of creating a desired hole in a workpiece using cutting tools (such as drills, reamers, and boring tools). These cutting tools rotate at high speeds and move linearly, creating friction and a cutting action against the workpiece material, removing excess material and forming the desired hole shape. Mechanical drilling is widely used in industrial production and can produce holes in a variety of materials, including metals, plastics, ceramics, and glass.

However, in actual use, there are still the following deficiencies: From a practical point of view, the device only clamps the two sides of the workpiece, which can easily cause the workpiece to move or shift in the other direction during the punching process, reducing the accuracy of the punching position and reducing the working efficiency of the device.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] See also Figure 1-4 The utility model provides a four-way positioning clamping device for a punching device, including a base 1, a connecting frame 2, a drill bit 3, a fixing mechanism 4 and a waste collection mechanism 5. The connecting frame 2 is fixedly connected to the top of the base 1, the drill bit 3 is arranged at the bottom front side of the connecting frame 2, the fixing mechanism 4 is arranged below the drill bit 3, and the waste collection mechanism 5 is arranged inside the top surface of the fixing mechanism 4.

[0024] The fixing mechanism 4 consists of a bottom frame 401, a motor 402, a screw rod 403, a top plate 404, a threaded plate 405, a fixed rod 406, a rotating seat 407, a connecting rod 408, an L-shaped connecting plate 409, a clamping block 410, a slider 411 and a slide rail 412. The bottom frame 401 is fixedly connected to the top of the base 1, the motor 402 is fixedly connected to the inside of the bottom frame 401, the screw rod 403 is rotatably connected to the top of the bottom frame 401, the screw rod 403 is connected to the output end of the motor 402, the top plate 404 is rotatably connected to the top surface of the screw rod 403, and the threaded plate 405 is threadedly connected to the outside of the screw rod 403.

[0025] Further as Figure 2 、 Figure 3 and Figure 4As shown, it is worth noting that the fixing rods 406 are symmetrically fixedly connected to the upper four sides of the bottom frame 401, and the top surface of the fixing rods 406 is fixedly connected to the top plate 404, and the threaded plate 405 is slidably connected to the fixing rods 406;

[0026] Since the threaded plate 405 is slidably connected to the outside of the fixed rod 406 , the threaded plate 405 is restricted from rotating along with the screw rod 403 , thereby ensuring that the threaded plate 405 performs a stable linear motion.

[0027] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that the rotating seat 407 is symmetrically fixedly connected to the four sides of the threaded plate 405, one end of the connecting rod 408 is rotatably connected to the upper inner part of the rotating seat 407, the L-shaped connecting plate 409 is rotatably connected to the other end of the connecting rod 408, and the clamping block 410 is fixedly connected to the other end of the L-shaped connecting plate 409.

[0028] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth noting that a rectangular groove is symmetrically opened on the top surface of the top plate 404, the slide rail 412 is fixedly connected to the inside of the rectangular groove, the slider 411 is slidably connected to the upper outside of the slide rail 412, and the slider 411 is fixedly connected to the clamping block 410;

[0029] By sliding the clamping block 410 above the slide rail 412 , the rotation of the connecting rod 408 can be converted into linear motion, thereby completing the linear motion of the clamping block 410 .

[0030] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth noting that a non-slip layer is provided on one side of the clamping block 410 close to the center of the top plate 404;

[0031] The anti-slip layer can increase the friction between the clamping block 410 and the workpiece, which can reduce the damage to the clamping of the clamping block 410 and improve the stability of the clamping.

[0032] According to the above working process, it can be seen that: through the setting of the fixing mechanism 4, the four sides of the workpieces of different sizes can be fixed, which can resist various forces and vibrations generated during the punching process, prevent the workpiece from being displaced during the punching process, ensure the accuracy of the punching position, and improve the flexibility and applicability of the processing.

[0033] Further as Figure 2 、 Figure 3 and Figure 4As shown, it is worth mentioning that the waste collection mechanism 5 is composed of a waste box 503 and a limiting bar 504. A groove 501 is provided in the middle of the top surface of the top plate 404, and limiting grooves 502 are symmetrically provided around the groove 501. The waste box 503 is adapted to the size of the groove 501.

[0034] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth noting that the limiting strips 504 are symmetrically fixedly connected to the four sides of the outer side of the waste box 503 , and the limiting strips 504 are slidably connected to the inside of the limiting groove 502 .

[0035] This solution has the following working process: when in use, first place the workpiece to be punched on the top of the top plate 404, then start the motor 402 to drive the screw rod 403 to rotate, because the threaded plate 405 is slidably connected to the outside of the fixed rod 406, the threaded plate 405 is restricted from rotating with the screw rod 403, thereby ensuring that the threaded plate 405 can move linearly stably, thereby driving the threaded plate 405 to move upward, and the rotating seat 407 around it drives the connecting rod 408 to rotate, driving the L-shaped connecting plate 409 to move, and the slider 41 1 slides above the slide rail 412, driving the L-shaped connecting plate 409 to follow the clamping block 410 to move toward the center of the top plate 404 until the anti-slip layer is close to the outer wall of the workpiece, thereby clamping and positioning the workpiece in all directions, thereby improving the positioning stability of the workpiece; then the workpiece is punched with the drill bit 3, and the waste generated by the punching falls into the interior of the waste box 503 below. After the punching is completed, the limiting bar 504 slides inside the limiting groove 502, and the waste box 503 is pulled out to dump the waste inside, thereby improving the convenience of the device.

[0036] In summary: through the setting of the fixing mechanism 4, the four sides of the workpieces of different sizes can be fixed, which can resist various forces and vibrations generated during the punching process, prevent the workpiece from being displaced during the punching process, ensure the accuracy of the punching position, and improve the flexibility and applicability of the processing; through the setting of the drill bit 3, the fixing mechanism 4 and the waste collection mechanism 5, during the punching process, the waste falls into the interior of the waste box 503 below. After the punching is completed, the waste box 503 can be pulled out upwards and the waste inside can be dumped for disposal, thereby improving the ease of use and cleanliness of the device.
