Description

Technical Field

[0001] This application relates to the field of drilling and tapping, and in particular to an automatic tapping device. Background Technology

[0002] Currently, tapping refers to using a certain torque to screw a tap into a pilot hole to create an internal thread. Rigid tapping is also known as synchronous feed tapping. When tapping injection-molded products, a hole is first drilled in the product, ensuring that the size of the drilled hole is smaller than the size of the threaded hole to facilitate subsequent tapping.

[0003] In the prior art, a tapping device for injection molded products includes a base, a fixed seat on the base, a clamping device for clamping the injection molded product on the fixed seat, a sliding seat that is raised and lowered on the base, a drive component on the base for controlling the raising and lowering of the sliding seat, a mounting socket rotatably connected to the sliding seat for mounting a tap or drill bit, and a drive motor on the sliding seat for driving the mounting socket to rotate.

[0004] Regarding the aforementioned patents, existing injection molded products have lower hardness compared to iron products, resulting in lower requirements for drilling and tapping. Existing injection molded product processing is usually non-standardized, with a large number of products per batch. When tapping, a large number of tapping holes are usually required. However, existing technology uses a single drill bit for processing, which greatly reduces the efficiency of processing injection molded products and urgently needs improvement. Summary of the Invention

[0005] In order to improve the processing efficiency of injection molded products and ensure the processing effect of the products, this application provides an automatic tapping device.

[0006] The automatic tapping device provided in this application adopts the following technical solution:

A first driving member for rotating the drive wheel is mounted on the base. A first mounting rod is rotatably connected to the limiting rotating seat. A first driven wheel meshing with the drive gear is mounted on the first mounting rod. A guide arc plate is mounted on the limiting rotating seat. The guide arc plate is coaxially arranged with the drive wheel. A plurality of guide rotating seats are slidably mounted on the guide arc plate.

A sliding seat is slidably connected to the base. A third driving member for moving the sliding seat closer to the first mounting rod is mounted on the base. A clamping device for clamping injection molded products is provided on the sliding seat.

[0008] By adopting the above technical solution, during operation, the operator adjusts the positions of multiple second drill rods according to the required drilling positions of the non-standard injection molded products and the position of the first mounting rod, using the second drive component. This is combined with adjusting the clamping angle of the injection molded product. After positioning, the injection molded product is clamped by the clamping device and, under the action of the third drive component, pushed towards the first mounting rod. This allows for more convenient drilling of multiple holes. After batch processing, the tap is installed and tapping is performed, thus completing the processing of the injection molded product. This processing method ensures uniform spacing of the machined holes on the injection molded product, guaranteeing the processing accuracy of the same batch of products. Furthermore, even after changing the tap, precise alignment of the machined holes remains, ensuring the drilling and tapping effect. On the other hand, processing multiple holes simultaneously greatly improves the efficiency of injection molded product processing and enhances the ease of use of the automatic tapping equipment.

[0009] Preferably, the mounting device includes a mounting socket fixed to the ends of the first and second mounting rods. The mounting socket has a mounting hole with a retaining ring for inserting a tap inside. The retaining ring has multiple clamping plates for clamping the tap, with the thickness of the clamping plates gradually decreasing away from the retaining ring. A clamping nut is threaded onto the mounting socket, and a clamping ring is provided on the inner wall of the clamping nut. The inner diameter of the clamping ring gradually increases towards the retaining ring. The clamping plates are inserted into the clamping ring, and when the clamping nut is tightened, the clamping ring pushes the clamping plates to grip the tap. A rotating slot is provided on the side of the guide rotor near the mounting socket, which is inserted into the clamping nut. A fourth driving component is provided on the base to drive the guide arc plate to move towards the clamping nut.

[0010] By adopting the above technical solution, when in use, the operator inserts the tap or drill bit into the fixing ring. The fourth driving component pushes the guide rotary seat towards the clamping nut and limits the clamping nut by rotating the socket. At this time, the first driving component drives the first mounting rod to rotate, thereby rotating the clamping nut, which in turn pushes the clamping ring to clamp the tap, thus achieving the purpose of fixing the tap. This design makes it easier to fix the tap and drill bit, improving the convenience of using the equipment.

[0011] Preferably, the clamping device includes a clamping cavity formed on the sliding seat, the clamping cavity extending through the side of the sliding seat near the first mounting rod, two clamping pieces for clamping the injection molded product are slidably connected in the clamping cavity, and a fifth driving member is provided on the sliding seat for pulling the two clamping pieces closer to each other.

[0016] By adopting the above technical solution, the clamping plate, in conjunction with the rotating clamping plate, can be better applied to various injection molded products of different shapes, improving the stability of the injection molded product positioning. Furthermore, during the sliding process of the clamping plate, when the area of ​​the first collection cavity is larger than the area of ​​the injection molded product, a larger space may be exposed on the side wall of the first collection cavity. During the clamping process of the clamping plate clamping the injection molded product, the sliding insert plate can be pulled to close part of the space of the first collection cavity under the action of the male and female magnetic blocks, increasing the internal collection pressure of the first collection cavity and ensuring the waste collection effect.

[0020] By adopting the above technical solution, the auxiliary insertion rod and auxiliary positioning control work together to lock the distance between the auxiliary positioning seat and the surface of the injection molded product. With the two infrared positioners illuminating the surface of the injection molded product, the operator can perform positioning more accurately, improving the accuracy of drilling and tapping. Furthermore, the auxiliary positioning slider and auxiliary positioning seat work together to support the drill bit or lead screw, thereby reducing shaking and improving the stability of the equipment and the tapping effect. At the same time, the auxiliary positioning seat can push the auxiliary insertion rod to press the injection molded product, improving the stability of the injection molded product.

[0021] Preferably, a connecting groove is provided on both sides of the avoidance arc groove, and an adjusting slider is slidably connected in the connecting groove. The adjusting slider slides along the thickness direction of the auxiliary positioning seat, and a baffle group is rotatably connected to the adjusting slider. The baffle group consists of multiple shielding plates that are hinged to each other. The shielding plates are rotatably connected to both sides of the auxiliary positioning slider to close the avoidance arc groove.

[0022] By adopting the above technical solution, during the sliding of the assisted positioning slider, the shield can be used to close the arc groove, thereby reducing the splashing of waste material towards the first mounting rod, allowing the waste material to enter the second mobile phone cavity better, improving the convenience of waste collection, and improving the cleanliness of the equipment.

[0023] Preferably, both the first mounting rod and the second mounting rod are provided with a support rod on the side near the base. The support rod is rotatably connected to a support rotating seat on the side near the base. The base is provided with a support arc groove that slides and engages with the support rotating seat.

[0026] By adopting the above technical solution, a reset spring can be used to assist the sliding seat in resetting, thereby enabling the sliding block to move away from the first mounting rod more conveniently and efficiently, improving the disassembly efficiency of injection molded products and enhancing the ease of use of the equipment.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During operation, the operator adjusts the positions of multiple second drill rods according to the required drilling locations of the non-standard injection molded product and the position of the first mounting rod via the second drive component. This is done in conjunction with adjusting the clamping angle of the injection molded product. After positioning, the injection molded product is clamped by the clamping device and pushed closer to the first mounting rod by the third drive component. This allows for more convenient drilling of multiple holes. After batch processing, taps are installed and tapping is performed, thus completing the processing of the injection molded product. This processing method ensures uniform spacing of the machined holes on the injection molded product, guaranteeing the processing accuracy of the same batch of products. Furthermore, it ensures precise alignment of the machined holes even after subsequent tap replacements, guaranteeing the drilling and tapping effect. Additionally, processing multiple holes simultaneously significantly improves the efficiency of injection molding and enhances the ease of use of the automatic tapping equipment.

[0029] 2. In use, the operator inserts the tap or drill bit into the retaining ring. The fourth drive component pushes the guide rotor towards the clamping nut and limits the clamping nut by rotating the socket. At this time, the first drive component drives the first mounting rod to rotate, thereby rotating the clamping nut. This causes the clamping ring to push the clamping plate to hold the tap tightly, thus achieving the purpose of fixing the tap. This design makes it easier to fix the tap and drill bit, improving the convenience of using the equipment.

[0030] 3. The rotating clamping plate, in conjunction with the holding plate, is better suited for various injection molded products of different shapes, improving the stability of product positioning. During the sliding of the clamping plate, when the area of ​​the first collection cavity is larger than the area of ​​the injection molded product, a significant portion of the sidewall of the first collection cavity may be exposed. As the clamping plate clamps the injection molded product, the sliding insert plate can be pulled to close part of the space in the first collection cavity under the action of the male and female magnetic blocks, increasing the internal collection pressure of the first collection cavity and ensuring effective waste collection.

[0043] The following is in conjunction with the appendix Figure 1 - Figure 11 This application will be described in further detail.

[0044] This application discloses an automatic tapping device.

[0045] Example 1

[0046] Reference Figure 1 An automatic tapping device includes a base 1, which is a rectangular frame with multiple support bases at the bottom. An installation cavity is formed within the base 1. A limiting rotary seat 5 is fixed on the base 1, and a drive wheel is rotatably connected to the limiting rotary seat 5. The drive wheel consists of a first rotating wheel 10 and a second rotating wheel 15 meshing together. The first rotating wheel 10 is smaller than the second rotating wheel 15, thus allowing for better transmission and increased drive speed. A first driving component 9, which is a stepper motor, is fixed on the base 1 to drive the first rotating wheel 10. A first mounting rod 14 is rotatably connected to the limiting rotary seat 5, and the first mounting rod adopts a fixed-point rotation design. A first driven wheel 13, meshing with the second rotating wheel 15, is fixedly mounted on the first mounting plate. A guide arc plate 26 is fixed on the limiting rotating seat 5, coaxially arranged with the second rotating wheel 15. At least two guide rotating seats 28 are slidably connected to the guide arc plate 26, and a second mounting rod 12 is rotatably connected to the guide rotating seat 28. A second driven wheel 11, meshing with the second rotating wheel 15, is fixed on the second mounting rod 12. A second driving member 29, which is a cylinder, is rotatably connected to the side wall of the guide arc plate 26 for driving the rotation of the guide rotating seat 28. The first mounting rod 14 passes through another guide rotating wheel, thereby limiting the first mounting rod 14. A clamping device for clamping taps or drill bits is installed at the end of the first mounting rod 14 and the second mounting rod 12 away from the first driven wheel 13. A sliding seat 3 is slidably connected to the base 1. A third driving component 2, which is a cylinder, is fixed on the base 1 to drive the sliding seat 3 to move closer to the first mounting rod 14. A clamping device for clamping the injection molded product 4 is fixed on the sliding seat 3. By using multiple machining holes to process simultaneously, the efficiency of processing the injection molded product 4 can be greatly improved, and the ease of use of the automatic tapping equipment can be enhanced.

[0047] A support rod 32 is fixed to the side of the first mounting rod 14 and the second mounting rod 12 near the machine base 1. The support rod 32 is coaxially arranged with the first mounting rod 14 or the second mounting rod 12. A support rotating seat 30 is rotatably connected to the side of the support rod 32 near the machine base 1. A bearing is provided between the support rotating seat 30 and the support rod 32 to facilitate the rotation of the support rod 32. A support arc groove 31 is provided on the machine base 1 to slide and engage with the support rotating seat 30. The support arc groove 31 is coaxially arranged with the drive gear, thereby supporting the first mounting rod 14 and the second mounting rod 12, improving the stability of the rotation of the first mounting rod 14 and the second mounting rod 12, and improving the drilling and tapping effect. A fixing block 8 is fixed on the machine base 1. A return spring 7 is fixed between the fixing block 8 and the sliding seat 3. The return spring 7 is used to pull the sliding seat 3 away from the first mounting rod 14, so that the sliding seat 3 can move away from the first mounting rod 14 more conveniently and efficiently, improving the disassembly efficiency of the injection molded product 4 and improving the convenience of using the equipment.

[0048] The mounting device includes a mounting socket 33, which is fixed to the ends of the first mounting rod 14 and the second mounting rod 12. The mounting socket 33 has a mounting hole 24, within which a retaining ring 18 for inserting a tap is fixed. Multiple clamping plates 20 for clamping the tap are integrally formed on the retaining ring 18, with cavities formed between the clamping plates 20. The thickness of the clamping plates 20 gradually decreases in the direction away from the retaining ring 18. A clamping nut 17 is threaded onto the mounting socket 33, and a clamping ring 19 is integrally formed on the inner wall of the clamping nut 17. The clamping plates 20 and the clamping ring 19 are inserted into each other. The inner diameter of the clamping ring 19... The tap gradually increases in size towards the retaining ring 18. When the clamping nut 17 is tightened, the clamping ring 19 pushes the clamping plate 20 to hold the tap. The guide rotary seat 28 has a rotating slot 25 on the side near the mounting socket 33 that engages with the clamping nut 17. A fourth driving component 27 is fixed on the base 1 to drive the guide arc plate 26 to move towards the clamping nut 17. The fourth driving component 27 is a driving cylinder, which can rotate the clamping nut 17, thereby causing the clamping ring 19 to push the clamping plate 20 to hold the tap, thus achieving the purpose of fixing the tap. This design makes it easier to fix the tap and the drill bit, improving the convenience of using the equipment.

[0049] The clamping device includes a clamping cavity 23 formed on the sliding base 3, which extends through the sliding base 3 near the first mounting rod 14. Two clamping plates 34 for clamping the injection-molded product 4 are slidably connected within the clamping cavity 23. A fifth driving member 35, consisting of two driving cylinders, is fixed on the sliding base 3 to pull the two clamping plates 34 closer together, thereby allowing the injection-molded product 4 to be more stably fixed. A rotating clamping plate 37 is rotatably connected to the clamping plate 34, which abuts against the injection-molded product 4. A limit spring 36 connects between the clamping plate 34 and the rotating clamping plate 37. The clamping plate 34, in conjunction with the rotating clamping plate 37, can better accommodate various shapes of injection-molded products 4, improving the positioning stability of the injection-molded product 4.

[0050] A vacuum cleaner 6 is fixed on the base 1, and a suction pipe 16 is connected to the vacuum cleaner 6. A suction hole is provided on the sliding base 3 to mate with the suction pipe 16. A first collection chamber 22 is provided on the side of the sliding base 3 near the first mounting rod 14. A second collection chamber 21, communicating with the first collection chamber 22, is provided at the bottom of the clamping chamber 23. The first collection chamber 22 and the second collection chamber 21 are used to collect waste material from both sides of the injection-molded product 4. This reduces the impact of waste material on the positioning of the injection-molded product 4, improves the positioning accuracy of the injection-molded product 4, and ensures the overall cleanliness of the equipment.

[0051] The first collection cavity 22 has sliding slots 41 on both sides. The depth direction of the sliding slots 41 is set along the sliding direction of the clamping piece 34. A sliding insert plate 38 is slidably connected in the sliding slots 41. The sliding insert plate 38 is used to control the opening area of ​​the clamping cavity 23. A male magnetic block 40 is fixed on the side of the sliding insert plate 38 near the clamping piece 34. A female magnetic block 39 that attracts the male magnetic block 40 is fixed on the clamping piece 34. Thus, when the area of ​​the first collection cavity 22 is larger than the area of ​​the injection molded product 4, more space is exposed on the side wall of the first collection cavity 22. During the process of clamping the injection molded product 4 by the clamping piece 34, the sliding insert plate 38 can be pulled to close part of the space of the first collection cavity 22 under the action of the male magnetic block 40 and the female magnetic block 39, thereby increasing the internal collection pressure of the first collection cavity 22 and ensuring the collection effect of waste.

[0052] The implementation principle of an automatic tapping device according to an embodiment of this application is as follows: During operation, the operator uses a tool to insert a tap or drill bit into the clamping ring 19. The fourth drive component 27 controls the guide rotor 28 to insert into the clamping nut 17. When the first mounting rod 14 rotates, the clamping nut 17 can be tightened, thereby causing the clamping ring 19 to push the clamping plate 20 to hold the tap, achieving the purpose of fixing the tap. According to the required drilling position of the non-standard injection molded product 4, and according to the position of the first mounting rod 14, the operator adjusts the position of multiple second drill rods through the second drive component 29, and adjusts the clamping angle of the injection molded product 4 in conjunction with the adjustment. After positioning, the injection molded product 4 is clamped by the clamping device, and under the action of the third drive component 2, the injection molded product 4 is pushed to move closer to the first mounting rod 14, thereby making it easier to drill multiple holes. On the one hand, it can make the spacing of the machining holes on the injection molded product 4 uniform, ensuring the machining accuracy of the same batch of products, and after the tap is replaced in the future, it can still accurately connect the machining holes to ensure the drilling and tapping effect of the product. On the other hand, the method of machining multiple machining holes at the same time can greatly improve the efficiency of machining injection molded product 4 and improve the convenience of using automatic tapping equipment.

[0053] Example 2

[0054] Reference Figure 9 The difference between this embodiment and embodiment 1 is that a locking plate 46 is slidably connected to the side of the rotating clamping plate 37 away from the clamping plate 34. The locking plate 46 is slidably arranged along the sliding direction of the sliding seat 3. A locking spring 45 is fixed on the clamping plate 34 to push the locking plate 46 closer to the injection molded product 4. A guide plate 42 is fixed on the locking plate 46. The guide plate 42 is inclined towards the sliding seat 3 in a vertically downward direction, thereby reducing the possibility of the injection molded product 4 tipping over, improving the stability of the injection molded product 4, and ensuring the drilling and tapping effect of the injection molded product 4.

[0055] An auxiliary positioning seat 50 is slidably connected to the base 1. The auxiliary positioning seat 50 slides in the same direction as the sliding seat 3. An avoidance groove 49 is provided on the auxiliary positioning seat 50, and an auxiliary positioning slider 47 for inserting a drill bit is slidably connected within the avoidance groove 49. An auxiliary positioning hole 48 is provided on the auxiliary positioning seat 50. An auxiliary insertion rod 44 is fixed on the locking plate 46. The auxiliary insertion rod 44 is inserted and cooperates with the auxiliary positioning control. A limiting protrusion 43 is fixed on the auxiliary insertion rod 44, and the limiting protrusion 43 abuts against the auxiliary positioning seat 50, thereby better limiting the distance between the auxiliary positioning seat 50 and the surface of the injection molded product 4. Two infrared positioners 51 at different positions are fixed on both sides of the auxiliary positioning slider 47. The infrared positioners 51 alternately illuminate the surface of the injection molded product 4 for positioning. This greatly improves the drilling accuracy of the injection molded product 4.

[0056] Both sides of the avoidance arc groove 49 are provided with connecting slide grooves 53. The connecting slide grooves 53 are dovetail grooves. An adjusting slider 52 is slidably connected in the connecting slide grooves 53. The adjusting slider 52 is a dovetail block. The adjusting slider 52 slides along the thickness direction of the auxiliary positioning seat 50. A baffle group is rotatably connected to the adjusting slider 52. The baffle group consists of multiple shielding plates 54 that are hinged to each other. The shielding plates 54 are plastic plates. The shielding plates 54 are rotatably connected to both sides of the auxiliary positioning slider 47 to close the avoidance arc groove 49. When the auxiliary positioning slider 47 moves, the avoidance arc groove 49 can be better closed, reducing the splashing of waste and making it easier to inject waste into the second collection chamber 21.

[0057] The implementation principle of Example 2 is as follows: During use, the injection molded product 4 is pressed by the locking plate 46, and the distance between the auxiliary positioning seat 50 and the injection molded product 4 is kept stable under the action of the auxiliary positioning seat 50 and the auxiliary insertion rod 44. On the one hand, under the action of the two infrared positioners 51, the drilling position can be determined more accurately, improving the drilling effect. On the other hand, the auxiliary positioning seat 50 and the auxiliary positioning slider 47 can provide auxiliary support for the longer drill bit and tap, reducing the shaking or even breakage of the drill bit and tap, and improving the drilling and tapping effect.

[0058] 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.
