[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the self-cleaning drilling equipment for mold processing with guiding positioning adopts a new structural design, and can quickly clamp and fix workpieces of different sizes through the provided clamping block, and also provides a nozzle that can swing back and forth so that the water flow can take away the debris, and also separates the coolant and the debris through the receiving box, so as to facilitate the reuse of the coolant. The specific contents are as follows: The self-cleaning drilling equipment for mold processing with guiding positioning, when working, places the mold in an arc position on the working plate, then starts the motor, so that the motor drives the threaded rod to rotate, and the threaded rod and the guide rod cooperate to drive the upper connecting plate, the clamping plate and the clamping block to work, and finally the clamping blocks on the front and rear sides are close to each other to clamp and fix the workpiece. The operation process is fast and convenient, and molds of different sizes can be quickly clamped, and then the drilling head at the end of the mechanical arm can be used for processing; Furthermore, the clamping blocks are evenly spaced on the surface of the clamping plate, so that the clamping blocks can better clamp the workpiece, improving stability. At the same time, the arc-shaped structure of the processing area of ​​the work plate allows the debris to slide directly off, making it easier to clean. The self-cleaning drilling equipment for mold processing with directional positioning starts the water pump inside the material box when drilling. At this time, the water pump provides coolant to the nozzle through the hose and the butt pipe, thereby cooling the nozzle and ensuring the normal operation. Furthermore, when the clamping plate moves to the middle position of the working plate, the connecting shaft will be driven to rotate through the traction rope, and the torsion spring will be stretched at this time. When the clamping plate moves back, the connecting shaft will rotate under the action of the torsion spring. When the connecting shaft rotates, it will drive the connecting plate and the first magnet to rotate synchronously. Then, the long pin, the pipe sleeve and the nozzle will swing back and forth on the surface of the vertical plate under the action of the mutual repulsive magnetic force between the first magnet and the second magnet and their own gravity. That is, after the drilling is completed, when the clamping plate releases the mold, the nozzle can spray coolant back and forth, and the water flow can take away the debris at this time, which plays a role of self-cleaning. Furthermore, during the rotation of the pipe sleeve and the nozzle, the positioning rod plays a role in limiting the maximum rotation distance of the pipe sleeve, thereby improving stability; (3) The self-cleaning type drilling equipment for mold processing capable of guiding positioning has a collecting bucket placed on the lower surface of the receiving box, so that during operation, the chips and coolant are collected by the receiving box, and the filter screen separates the solid and the liquid; Furthermore, when the connecting shaft rotates, the connecting shaft will drive the cam to rotate synchronously, and then the cam will intermittently contact the sliding block. At this time, the sliding block performs reciprocating linear motion in the horizontal direction under the action of the cam thrust, the limit rod and the connecting spring. At this time, the material receiving box moves synchronously, and then the material receiving box can better discharge the coolant, which is convenient for the recovery of the coolant. Furthermore, when it is necessary to take out the debris inside the receiving box, the side plate can be directly lifted upward to move the side plate out of the hook, and the debris inside the receiving box can be processed at this time.

[0019] Embodiment 1: By setting the threaded rod 5 and the guide rod 6 which plays a guiding role, the clamping plate 7 and the clamping block 8 can work quickly to clamp the mold for easy drilling processing, such as Figure 1-Figure 4 As shown: A self-cleaning drilling device for mold processing that can be guided and positioned, comprising a working plate 1, a mechanical arm 3 and a material receiving box 14, wherein the lower surface of the working plate 1 is fixedly connected with a base, and the upper surface of the working plate 1 is bolted with a vertical plate 2, and the outer wall of the vertical plate 2 is threadedly connected with a motor 4, the mechanical arm 3 is bolted with the inner wall of the vertical plate 2, and the end of the mechanical arm 3 is connected with a drill bit, the material receiving box 14 is movably arranged on the lower surface of the working plate 1, and the side of the material receiving box 14 is fixedly connected with a side plate 29; A self-cleaning drilling device for mold processing capable of guiding and positioning, further comprising: A threaded rod 5, the threaded rod 5 is fixedly connected to the output end of the motor 4, and an upper connecting plate 9 is threadedly connected to the surface of the threaded rod 5, and a clamping plate 7 is fixedly connected to the lower surface of the upper connecting plate 9, and a clamping block 8 is fixedly connected to the surface of the clamping plate 7; A material box 10, the material box 10 is bolted to the upper surface of the left side of the working plate 1, and a water pump is bolted to the inner wall of the material box 10, and a vertical plate 12 is fixedly connected to the upper surface of the working plate 1, and the surface of the vertical plate 12 is convex; A transition rod 11, the transition rod 11 is fixedly connected to the upper surface of the working plate 1, a connecting shaft 13, the connecting shaft 13 is rotatably arranged inside the working plate 1, and a cam 23 is fixedly connected to the lower surface of the connecting shaft 13, and a limit plate 25 is fixedly connected to the middle surface of the connecting shaft 13; A long pin 16 is rotatably arranged inside the vertical plate 12, and a pipe sleeve 17 is sleeved and connected to the surface of the long pin 16, and a nozzle 18 is fixedly connected to the surface of the pipe sleeve 17, and a butt pipe is fixedly connected to the upper surface of the nozzle 18, and the butt pipe is connected to the water pump inside the material box 10 through an external hose; A sliding block 27 is slidably arranged on the lower surface of the working plate 1, and a hook 28 is fixedly connected to the lower surface of the sliding block 27, and a side plate 29 is sleeved and connected to the surface of the hook 28, the upper connecting plate 9 is symmetrically distributed about the center of the working plate 1, and the middle position of the working plate 1 is an arc structure, and a through hole is opened on the surface of the working plate 1, the front and rear sides of the threaded rod 5 have opposite spiral rotation directions, and a guide rod 6 is fixedly connected to the inner wall of the vertical plate 2, and the guide rod 6 runs through the interior of the upper connecting plate 9.

[0020] During work, the mold is placed in an arc position on the working plate 1, and then the motor 4 on the outer wall of the vertical plate 2 is started, so that the motor 4 drives the threaded rod 5 to rotate, and the threaded rod 5 cooperates with the guide rod 6 to drive the upper connecting plate 9, the clamping plate 7 and the clamping block 8 to work. Finally, the clamping blocks 8 on the front and rear sides are close to each other to clamp and fix the workpiece. The operation process is quick and convenient, and molds of different sizes can be quickly clamped, and then the drilling head at the end of the robot arm 3 can be used for processing. The clamping blocks 8 are evenly spaced on the surface of the clamping plate 7, so that the clamping blocks 8 can better clamp the workpiece and improve stability. At the same time, the arc structure of the processing area of ​​the working plate 1 allows debris to slide down directly, which is easy to clean.

[0021] Embodiment 2: Different from Embodiment 1, the nozzle 18 can not only quickly cool down, but also make the water flow drive the debris, which has a self-cleaning effect. Figure 5-Figure 8 As shown: A traction rope 15 is fixedly connected to the surface of the clamping plate 7, and the surface of the traction rope 15 fits the surface of the transition rod 11, and the end of the traction rope 15 is wrapped and fixedly connected to the surface of the connecting shaft 13, the upper end of the connecting shaft 13 is fixedly connected to a connecting plate 19, and the upper surface of the connecting plate 19 is fixedly connected to a first magnet 20, and the first magnet 20 is distributed at equal angles on the surface of the connecting plate 19.

[0022] The surface of the long pin 16 is convex, and the lower surface of the long pin 16 is fixedly connected to a second magnet 21 corresponding to the first magnet 20, and the magnetic poles of the lower surface of the second magnet 21 are the same as the magnetic poles of the upper surface of the first magnet 20. A positioning rod 24 is fixedly connected to the inner wall of the vertical plate 12, and the nozzles 18 are evenly spaced on the surface of the sleeve 17.

[0023] When drilling, start the water pump inside the material box 10. At this time, the water pump provides coolant to the nozzle 18 through the hose and the docking tube, so that the nozzle 18 plays a role in cooling, ensuring the normal operation of the work. When the clamping plate 7 moves to the middle position of the working plate 1, the connecting shaft 13 will be driven to rotate inside the working plate 1 through the traction rope 15. At this time, the torsion spring 22 will be stretched, and when the clamping plate 7 moves back, the connecting shaft 13 will rotate under the action of the torsion spring 22. When the connecting shaft 13 rotates, it will drive the connecting plate 19 and the first magnet 20 to rotate synchronously. When the first magnet 20 rotates to approach the second magnet 21, the long pin 16 rotates upward under the action of the repulsive magnetic force, and the first magnet 20 continues to rotate to away from the second magnet At 21, the long pin 16 descends under the action of its own gravity, and the above process is repeated. The long pin 16, the sleeve 17 and the nozzle 18 swing back and forth on the surface of the vertical plate 12 under the action of the mutual repulsive magnetic force between the first magnet 20 and the second magnet 21 and their own gravity. That is, after the drilling is completed, when the clamping plate 7 releases the mold, the nozzle 18 can spray coolant back and forth. At this time, the water flow can take away the debris, which plays a self-cleaning role. During the rotation of the sleeve 17 and the nozzle 18, the positioning rod 24 limits the maximum rotation distance of the sleeve 17, thereby improving stability (when the connecting shaft 13 rotates under the action of the torsion spring 22, the traction rope 15 will be reeled in, and at the same time, the limit plate 25 limits the position where the traction rope 15 is reeled in, thereby ensuring stability).

[0024] Embodiment 3: Different from Embodiment 2, the material receiving box 14 is provided to collect the chips and coolant in the processing process. Figure 9-11 As shown: A limiting rod 30 is fixedly connected to the lower surface of the working plate 1, and a sliding block 27 is sleeved and connected to the surface of the limiting rod 30, and the sliding block 27 is symmetrically distributed about the center of the working plate 1. A connecting spring 31 that plays an elastic reset role is fixedly connected to the surface of the sliding block 27, and the other side of the connecting spring 31 is fixedly connected to the inner wall of the working plate 1.

[0025] The receiving box 14 is a structure that is wide at the top and narrow at the bottom, and a filter screen 26 is fixedly connected to the lower surface of the receiving box 14. A torsion spring 22 that plays an elastic reset role is fixedly connected to the surface of the connecting shaft 13, and the other side of the torsion spring 22 is fixedly connected to the inner wall of the working plate 1.

[0026] During operation, a collecting bucket can be placed on the lower surface of the receiving box 14, and then during operation, the debris and coolant will be collected by the receiving box 14, and the filter screen 26 separates the solid and the liquid, so that the liquid is collected by the collecting bucket. At the same time, when the connecting shaft 13 rotates, the connecting shaft 13 will drive the cam 23 to rotate synchronously, and then the cam 23 will intermittently contact with the sliding block 27. When the sliding block 27 is pushed, the sliding block 27 moves in the direction of squeezing the connecting spring 31, and when the cam 23 continues to rotate until it does not push the sliding block 27, the sliding block 27 is in contact with the connecting spring 31. The sliding block 27 moves back under the action of the spring 31, that is, the sliding block 27 makes a reciprocating linear motion in the horizontal direction under the action of the thrust of the cam 23, the limit rod 30 and the connecting spring 31. At this time, the material receiving box 14 moves synchronously, and then the material receiving box 14 is in a vibrating state, that is, the material receiving box 14 can better discharge the coolant, which is convenient for the recovery of the coolant. When it is necessary to take out the debris inside the material receiving box 14, the side plate 29 can be directly lifted up to move the side plate 29 out of the hook 28. At this time, the debris inside the material receiving box 14 can be processed.

[0027] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
