Description

Technical Field

[0001] This invention relates to the field of electromagnetic valve cover processing technology, and in particular to a drilling device for electromagnetic valve cover processing equipment and its usage method. Background Technology

[0002] The processing equipment for solenoid valve covers includes a drilling device. Existing drilling devices of this type place the solenoid valve cover under a drilling rod and use the horizontal rotation and vertical movement of the drilling rod to drill holes. Since multiple holes need to be drilled on a valve cover, it is necessary to contact and limit the valve cover, then adjust the angle of the valve cover, and then prepare another hole. This method is relatively cumbersome, requiring multiple fixations of the valve cover and multiple contact fixations. Therefore, we propose a drilling device for processing solenoid valve covers and its usage method to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to solve the problems mentioned in the background art by providing a drilling device for a solenoid valve cover processing equipment and its usage method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A drilling device for processing electromagnetic valve covers includes multiple valve covers and a drilling platform fixed on multiple columns. A drilling component is installed on the drilling platform, and a motor slot is provided on the drilling platform. A second servo motor is fixedly installed in the motor slot, and a rotating shaft is fixedly installed on the drive end of the second servo motor. A drilling disc is installed on the rotating shaft through a rotating assembly. Multiple placement slots are provided along the circumference of the drilling disc, and a connected feeding hole is provided on the bottom wall of each placement slot. A receiving component that cooperates with the feeding hole is provided on the drilling platform. Each of the placement slots is equipped with a placement seat via a connecting assembly. An external gear ring I is mounted on the rotating shaft via a rotating component. Multiple transmission gears are rotatably mounted on the punching disc.

A stabilizing component is installed between the external gear ring I and the punching disc. The placement seat has a receiving groove that matches the valve cover, and each placement seat is equipped with a clamping component and a pressing and fixing component.

[0006] In the drilling device of the above-mentioned electromagnetic valve cover processing equipment, the rotating component includes a one-way bearing and a round hole. The one-way bearing is installed on the rotating shaft, and the drilling disc has a round hole that mates with the one-way bearing.

[0007] In the aforementioned drilling device of a solenoid valve cover processing equipment, the receiving component includes a receiving hole, an annular threaded groove, and a receiving cylinder. The drilling platform is provided with a receiving hole that matches the unloading hole. The lower surface of the drilling platform is provided with an annular threaded groove, and a receiving cylinder is threaded onto the annular threaded groove.

[0008] In the aforementioned drilling device of a solenoid valve cover processing equipment, the connecting assembly includes a shaft, a magnetic ring one, and a magnetic ring two. A shaft is rotatably mounted on the bottom wall of each placement slot, and the upper end of the shaft is fixedly connected to the corresponding placement seat. A magnetic ring one is fixedly mounted on the lower surface of each placement seat, and a magnetic ring two that cooperates with the magnetic ring one is fixedly mounted on the bottom wall of each placement slot. The magnetic rings one and two have opposite magnetic properties on their adjacent sides.

[0009] In the drilling device of the above-mentioned electromagnetic valve cover processing equipment, the rotating component includes a one-way bearing and a connecting rod. Multiple connecting rods are fixedly installed on the rotating shaft through the one-way bearing, and one end of the connecting rod is fixed to the inner wall of the outer toothed ring.

[0010] In the aforementioned drilling device of a solenoid valve cover processing equipment, the stabilizing component includes an annular groove one, a magnetic ring three, and a magnetic ring four. An annular groove one is provided on the drilling disc, a magnetic ring three is fixedly installed on the inner wall of the annular groove one, and a magnetic ring four is fixedly installed at the lower end of the external toothed ring one. The magnetic properties of the magnetic ring three and the magnetic ring four are opposite on the side that are close to each other.

[0011] In the drilling device of the above-mentioned electromagnetic valve cover processing equipment, the clamping component includes an annular groove II and a clamping rubber ring. An annular groove II is provided on the inner wall of each receiving groove, and a clamping rubber ring is fixedly installed in each annular groove II. The inner diameter of the clamping rubber ring is smaller than the inner diameter of the placement seat, and the upper and lower sides of the clamping rubber ring are arc-shaped.

[0012] In the drilling device of the above-mentioned electromagnetic valve cover processing equipment, the clamping and fixing component includes a threaded groove, a screw, a gear, a clamping block, a mounting ring, an internal gear ring, a limiting block, and a strip groove. Each of the placement seats has a threaded groove, and a screw is threadedly installed on each of the threaded grooves. Multiple gears are rotatably installed on each of the placement seats. Multiple limiting blocks are fixedly installed on each of the screws, and multiple strip grooves that cooperate with the limiting blocks are opened on the gears. A clamping block is fixedly installed on each of the screws. A mounting ring is threadedly installed on the outer side of each of the placement seats, and an internal gear ring that meshes with multiple gears is fixedly installed on the inner wall of each mounting ring. The clamping block consists of a lifting rod, a pressure block, and a vertical rod. Each screw is fixedly installed with a lifting rod, each lifting rod is fixedly installed with a vertical rod, and a pressure block is fixedly installed at the lower end of the vertical rod, and a rubber pad is fixedly installed at the lower end of the pressure block.

[0013] A method of using a punching device, including the solenoid valve cover described above, further includes the following steps: S1: First, place the valve cover that needs to be drilled into the placement seat, and then apply a rotational force to the mounting ring. The rotation of the mounting ring drives the corresponding gear to rotate through the internal gear ring. The rotation of the gear drives the screw to rotate, and the rotation of the screw drives the clamping block to rotate from the outside of the valve cover to abut against the valve cover. S2: Activate servo motor two. Servo motor two drives one-way bearing one to rotate through the rotating shaft. The rotation of one-way bearing one drives the drilling disc to rotate, thereby causing the placement seat to rotate directly below the drilling rod. In specific operation, the rotation of the drilling disc is controlled intermittently, so that the valve cover rotates sequentially to directly below the drilling rod. S3: The servo motor drives the rotating shaft to rotate. The rotation of the rotating shaft drives the transmission gear to rotate through the one-way bearing, connecting rod, and external gear ring. The rotation of the transmission gear drives the placement seat to rotate through the external gear ring. The rotation of the placement seat drives the valve cover located below the punching rod to rotate, thus punching the valve cover at different positions. S4: Start servo motor one. Servo motor one works and drives the lifting block to move vertically through the threaded rod. The movement of the lifting block drives the starting drilling motor to move vertically. The starting drilling motor drives the drilling rod to rotate, thereby performing drilling. S5: After drilling is completed, after the placement seat is moved to the position furthest away from the servo motor, remove the valve cover that has been drilled, and then place the new valve cover to be drilled.

[0014] Compared with existing technologies, the advantages of this invention are: 1. After the valve cover is placed in the mounting seat, it achieves an initial clamping effect under the action of the rubber ring. At the same time, by rotating the corresponding mounting ring, the valve cover can be quickly pressed and fixed, ensuring the accuracy of subsequent drilling.

[0015] 2: The valve cover can revolve relative to the rotating shaft and also relative to the placement slot, which facilitates multiple drilling of a single valve cover and drilling operations of other valve covers; at the same time, the matching arrangement of the drilling plate and the drilling table facilitates the picking and placing operation of the valve cover on the outermost placement seat.

[0016] 3: Through the coordinated operation of the threaded groove, screw, gear, clamping block, mounting ring, and internal gear ring, the device makes the clamping operation of the valve cover after placement simple. A rotational force is applied to the mounting ring by hand. At the same time, the mounting ring and the placement seat are threadedly connected, and the rotation has an automatic locking effect, which improves the stability of clamping.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figures 1-10 A drilling device for processing electromagnetic valve covers includes multiple valve covers (not shown in the figure) and a drilling platform 2 fixed on multiple columns 1. A drilling component is installed on the drilling platform 2. The drilling component consists of a lifting assembly, a lifting block 5, a drilling motor 6, and a drilling rod 7. The lifting block 5 is installed on the drilling platform 2 via the lifting assembly. The drilling motor 6 is fixedly installed on the lifting block 5. The driving end of the drilling motor 6 is fixedly installed with the drilling rod 7, and the drilling rod 7 rotates through the lifting block 5. The drilling component is used to perform the required drilling operation on the valve cover located directly below the drilling rod 7.

[0021] The lifting assembly includes a servo motor 3, a threaded rod 4, a support frame 8, and a vertical block (not shown in the figure). The vertical block is fixedly installed on the drilling table 2. The lifting block 5 has a square hole that mates with the vertical block. The servo motor 3 is fixedly installed on the drilling table 2. The drive end of the servo motor 3 is fixedly installed with the threaded rod 4, and the lifting block 5 is threaded onto the threaded rod 4. The vertical block and the square hole work together to limit the movement of the lifting block 5, so that the lifting block 5 can only move in the vertical direction. Alternatively, a cylinder and a telescopic rod can be used to replace the above-mentioned lifting assembly. The cylinder drives the telescopic rod to extend and retract, and this extension and retraction drives the drilling rod 7 to move in the vertical direction.

[0022] A support frame 8 is fixedly installed on the drilling table 2. The support frame 8 consists of a long rod, a short rod 19, and a round block 20. The long rod is fixedly installed on the drilling table 2, and the round block 20 is fixedly installed on the long rod through the short rod 19. The upper end of the threaded rod 4 is rotatably installed on the round block 20. The support frame 8 is set to provide rotational support for the upper end of the threaded rod 4, thereby improving the stability of the rotation of the threaded rod 4.

[0023] Reference Figures 1-10 The punching table 2 has a motor slot (not shown in the figure), and a servo motor 2 9 is fixedly installed in the motor slot. A rotating shaft 10 is fixedly installed at the drive end of the servo motor 2 9. The rotating shaft 10 is mounted on a punching disk 12 through a rotating assembly. The rotating assembly includes a one-way bearing 11 and a round hole 13. The one-way bearing 11 is installed on the rotating shaft 10, and the round hole 13 that mates with the one-way bearing 11 is opened on the punching disk 12. The rotating assembly allows the punching disk 12 to rotate when needed, and in a specific setting, the angle of each rotation is fixed, so that the next adjacent valve cover rotates to directly below the punching rod 7.

[0024] The punching disc 12 has multiple placement slots 14 along its circumference, and each placement slot 14 has a connected discharge hole 15 on its bottom wall. The punching table 2 has a receiving component that mates with the discharge hole 15. The receiving component includes a receiving hole, an annular threaded groove, and a receiving cylinder. The punching table 2 has a receiving hole that mates with the discharge hole 15. The lower surface of the punching table 2 has an annular threaded groove (not shown in the figure), and a receiving cylinder (not shown in the figure) is threaded onto the annular threaded groove. Through the cooperation of the receiving hole and the discharge hole 15, the debris generated by the punching rod 7 during the punching process can fall directly onto the receiving cylinder through the discharge hole 15 and the receiving hole. The receiving cylinder is threaded onto the punching table 2, making it easy to remove periodically and clean the debris collected inside.

[0025] The size of the discharge hole 15 is smaller than the diameter of the valve cover, or multiple circular holes can be directly provided. The circular holes are designed to cooperate with the punching rod 7, and their size is larger than the punching rod 7, so that the debris generated during the punching process can fall directly into the receiving cylinder. At the same time, the setting of the discharge hole 15 also facilitates the application of a removal force to the punched valve cover. When the punched valve cover is rotated to its farthest distance, the clamping force applied to the valve cover is first released, and then a force can be applied directly to the lower surface of the valve cover by hand through the discharge hole 15 to push its upper end out of the placement seat 16 (initially, the upper surface of the valve cover is flush with the upper surface of the placement seat 16).

[0026] Reference Figures 1-10Each placement slot 14 is equipped with a placement seat 16 via a connecting assembly. The connecting assembly consists of a shaft, a magnetic ring 17, and a magnetic ring 18. A shaft is rotatably mounted on the bottom wall of each placement slot 14, and the upper end of the shaft is fixedly connected to the corresponding placement seat 16. A magnetic ring 17 is fixedly mounted on the lower surface of each placement seat 16. A magnetic ring 18 that cooperates with the magnetic ring 17 is fixedly mounted on the bottom wall of each placement slot 14. The magnetic rings 17 and 18 have opposite magnetic properties on their adjacent sides. The cooperation between the magnetic rings 17 and 18 makes it difficult for the placement seat 16 to rotate easily when no external force is applied.

[0027] An external gear ring 23 is mounted on the rotating shaft 10 via a rotating component, and multiple transmission gears 24 are rotatably mounted on the punching disc 12. An external gear ring 23 that meshes with the corresponding transmission gear 24 is fixedly mounted on each placement seat 16. A stabilizing component is installed between the external gear ring 23 and the punching disc 12. The rotating component is designed to drive the corresponding placement seat 16 to rotate when needed, so as to facilitate punching multiple through holes on a single valve cover.

[0028] The rotating component includes a one-way bearing 21 and a connecting rod 22. Multiple connecting rods 22 are fixedly installed on the rotating shaft 10 via the one-way bearing 21, and one end of the connecting rod 22 is fixed to the inner wall of the outer toothed ring 23. The stabilizing component includes an annular groove 25, a magnetic ring 3, and a magnetic ring 4. An annular groove 25 is provided on the perforated plate 12. A magnetic ring 3 is fixedly installed on the inner wall of the annular groove 25. A magnetic ring 4 is fixedly installed at the lower end of the outer toothed ring 23, and the magnetic properties of the magnetic ring 3 and magnetic ring 4 are opposite on the side that are close to each other. Through the cooperation of magnetic ring 3 and magnetic ring 4, the outer toothed ring 23 is not easy to rotate even when it is not subjected to external force, further improving the stability of the placement seat 16.

[0029] Reference Figures 1-10 The placement seat 16 has a receiving groove 26 that mates with the valve cover. Each placement seat 16 is equipped with a clamping component, which includes an annular groove 27 and a pressing rubber ring 28. An annular groove 27 is provided on the inner wall of each receiving groove 26. A pressing rubber ring 28 is fixedly installed in each annular groove 27. The inner diameter of the pressing rubber ring 28 is smaller than the inner diameter of the placement seat 16, and the upper and lower sides of the pressing rubber ring 28 are arc-shaped. The setting of the pressing rubber ring 28 does not affect the normal placement of the valve cover, and at the same time, it provides a preliminary clamping effect during placement.

[0030] Each placement seat 16 is equipped with a clamping and fixing component; the clamping and fixing component includes a threaded groove 29, a screw 30, a gear 31, a clamping block 32, a mounting ring 33, an internal gear ring 34, a limiting block 35, and a strip groove. Each placement seat 16 has a threaded groove 29, and a screw 30 is threadedly installed on each threaded groove 29. Multiple gears 31 are rotatably installed on each placement seat 16. Multiple limiting blocks 35 are fixedly installed on each screw 30, and multiple strip grooves that cooperate with the limiting blocks 35 are opened on the gears 31. A clamping block 32 is fixedly installed on each screw 30. A mounting ring 33 is threadedly installed on the outer side of each placement seat 16, and an internal gear ring 34 that meshes with multiple gears 31 is fixedly installed on the inner wall of each mounting ring 33. The clamping block 32 consists of a lifting rod, a pressure block, and a vertical rod. Each screw 30 has a lifting rod fixedly installed on it, and each lifting rod has a vertical rod fixedly installed on it. A pressure block is fixedly installed at the lower end of the vertical rod, and a rubber pad is fixedly installed at the lower end of the pressure block. The rubber pad can improve the clamping effect on the valve cover and avoid direct contact, thereby improving the clamping and protection of the valve cover during subsequent drilling.

[0031] A method of using a punching device, including the aforementioned solenoid valve cover, further includes the following steps: S1: First, place the valve cover that needs to be drilled into the placement seat 16, and then apply a rotational force to the mounting ring 33. The rotation of the mounting ring 33 drives the corresponding gear 31 to rotate through the internal gear ring 34. The rotation of the gear 31 drives the screw 30 to rotate spirally. The rotation of the screw 30 drives the clamping block 32 to rotate from the outside of the valve cover to abut against the valve cover. S2: Turn on servo motor 29. Servo motor 29 works to drive one-way bearing 11 to rotate through rotating shaft 10. One-way bearing 11 rotates and drives punching disc 12 to rotate, so that the placement seat 16 rotates to the position directly below punching rod 7. In specific operation, the rotation of punching disc 12 is controlled intermittently, so that the valve cover rotates to the position directly below punching rod 7 in sequence. S3: The servo motor 29 drives the rotating shaft 10 to rotate in the same direction. The rotation of the rotating shaft 10 drives the transmission gear 24 to rotate through the one-way bearing 21, connecting rod 22, and external gear ring 23. The rotation of the transmission gear 24 drives the placement seat 16 to rotate through the external gear ring 2. The rotation of the placement seat 16 drives the valve cover located below the punching rod 7 to rotate, thus punching the valve cover at different positions. S4: Turn on servo motor 3. Servo motor 3 drives the lifting block 5 to move vertically through the threaded rod 4. The movement of the lifting block 5 drives the drilling motor 6 to move vertically. Turn on the drilling motor 6. The drilling motor 6 drives the drilling rod 7 to rotate, thereby drilling. S5: After the drilling is completed, after the placement seat 16 is moved to the position furthest away from the servo motor 3, remove the valve cover that has been drilled, and then place the new valve cover to be drilled.

[0032] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The mounting ring (33) rotates and drives the corresponding gear (31) to rotate through the internal gear ring (34). The gear (31) rotates and drives the screw (30) to rotate. The screw (30) rotates and drives the clamping block (32) to rotate, rotating from the outside of the valve cover to abut against the valve cover. S2: Turn on the servo motor 2 (9). The servo motor 2 (9) drives the one-way bearing 1 (11) to rotate through the rotating shaft (10). The rotation of the one-way bearing 1 (11) drives the punching disc (12) to rotate, thereby causing the placement seat (16) to rotate directly below the punching rod (7). In specific operation, the punching disc (12) is rotated intermittently, so that the valve cover rotates sequentially to directly below the punching rod (7). S3: The rotating shaft (10) is driven to rotate by the servo motor (9). The rotating shaft (10) rotates and drives the transmission gear (24) to rotate through the one-way bearing (21), connecting rod (22), and external gear ring (23). The transmission gear (24) rotates and drives the placement seat (16) to rotate through the external gear ring (2). The placement seat (16) rotates and drives the valve cover located below the punching rod (7) to rotate, thus punching the valve cover at different positions. S4: Start servo motor one (3), servo motor one (3) works to drive the lifting block (5) to move in the vertical direction through the threaded rod (4), the lifting block (5) moves to drive the starting drilling motor (6) to move in the vertical direction, the starting drilling motor (6) works to drive the drilling rod (7) to rotate, thereby drilling; S5: After the drilling is completed, after the placement seat (16) is moved to the position furthest away from the servo motor (3), remove the valve cover that has been drilled, and then place the new valve cover to be drilled.
