Description

Technical Field

[0001] This invention relates to the field of aviation plug rain cover manufacturing technology, and in particular to a drilling device for manufacturing circuit breaker aviation plug rain covers. Background Technology

[0002] The circuit breaker aviation plug rain cover is a protective device specifically designed for circuit breaker aviation plugs. It effectively prevents rainwater, dust, and other external debris from entering the aviation plug, protecting the electrical connection from moisture and contamination. Made of durable materials, the rain cover is moisture-proof, waterproof, and dustproof, ensuring stable operation of the circuit breaker aviation plug in various harsh environments and improving the safety and reliability of the electrical system.

[0003] In existing technologies, the drilling of rain covers is done manually, which cannot effectively hold the rain cover for batch drilling. At the same time, after drilling the rain cover, the burrs on the inner wall of the hole cannot be removed, which requires workers to perform secondary processing separately. It is also difficult to control the grinding force, resulting in poor drilling quality and low efficiency. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, by providing a clamping and conveying assembly and a deburring assembly, the rain cover body can be automatically conveyed on the outer shell of the device and clamped and fixed during the conveying process, realizing batch drilling operations. At the same time, it can remove burrs from the inner wall after drilling, eliminating the need for manual secondary processing and polishing, uniformly controlling the polishing force, improving the drilling quality, and increasing drilling efficiency.

[0017] 2. In this invention, by providing an ejection mechanism and a driving mechanism, the rain cover body clamped on the support plate can be lifted by the combined action of the extrusion roller and the extrusion groove after drilling, so that the ejection block can push the rain cover body out of the support plate, thereby allowing the rain cover body after drilling to be quickly detached, thus improving the drilling efficiency and making it easier for workers to use.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1, as Figure 1 and Figure 2 As shown, a drilling device for producing rainproof covers for circuit breaker aviation plugs includes a device housing 1 and a rainproof cover body 5. Support legs 2 are fixedly connected to the four corners of the lower end of the device housing 1. A control box 3 is fixedly installed in the middle of the front end of the device housing 1. A control box 3 is fixedly installed in the middle of the upper end of the device housing 1. A drilling mechanism 4 is fixedly installed in the middle of the upper end of the device housing 1. A clamping and conveying assembly 6 is provided in the inner cavity of the device housing 1. A deburring assembly 7 is provided at the left end and the upper end of the device housing 1.

[0034] In this embodiment, the rain cover 5 is placed on the clamping and conveying assembly 6. At this time, the control box 3 causes the clamping and conveying assembly 6 to move the rain cover body 5 towards the rear of the device housing 1, clamping and fixing the rain cover body 5. This allows the rain cover body 5 to be cleaned of dust and debris on its outer surface by the deburring assembly 7, and lubricant can be applied to the perforated areas. When it moves to the set position, the perforating mechanism 4 performs a perforation operation on the rain cover body 5. After perforation, the deburring assembly 7 removes burrs from the inner wall of the perforation.

[0035] The control box 3 mentioned above is a mature control technology and a mature control device in the existing technology. In this solution, its controllable functions are utilized, and its structure and principle will not be described further.

[0036] The aforementioned drilling mechanism 4 is a mature drilling technology and equipment in the prior art. In this solution, it is used to drill holes in the rain cover body 5. Its structure and principle will not be described further.

[0037] Specifically, in order to clamp and transport the rain cover body 5, refer to... Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 In this embodiment, the clamping and conveying assembly 6 includes a first rotating rod 61 that passes through the left end of the device housing 1 symmetrically and extends to the right end of the device housing 1 and is rotatably connected. A pressing plate 66 is fixedly connected to the inner surface of the device housing 1 symmetrically. A driving mechanism 62 is provided on the outer surface of the first rotating rod 61. A clamping mechanism 63 is symmetrically provided on the upper end of the driving mechanism 62. An ejection mechanism 64 is provided on both the left and right sides of the inner surface of the device housing 1. A T-shaped hole 67 communicating with the inner surface of the device housing 1 is opened in the middle of the upper end of the device housing 1. A connecting plate 68 is slidably connected to the upper part of the inner surface of the T-shaped hole 67. A protective mechanism 65 is symmetrically provided at the front and rear ends of the connecting plate 68.

[0038] For further details, please refer to [link / reference]. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In this embodiment, the clamping mechanism 63 includes a connecting block 631 fixedly connected to the upper left part of the slider 624. A circular plate rectangular rod 632 is slidably connected to the inner surface of the connecting block 631. A first connecting rod 633 is fixedly connected to the middle of the right end of the circular plate rectangular rod 632. A circular block 634 is rotatably connected to the lower part of the outer surface of the first connecting rod 633. A ring 635 is fixedly connected to the right end of the connecting block 631 and slidably connected to the outer surface of the circular plate rectangular rod 632. A first spring 6 is sleeved on the outer surface of the circular plate rectangular rod 632. 36. The two ends of the first spring 636 are fixedly connected to the right end of the connecting block 631 and the left end of the circular plate of the circular plate rectangular rod 632, respectively. The left end of the circular plate rectangular rod 632 is fixedly connected to a support plate 637. The upper end of the connecting plate 68 is symmetrically provided with sliding grooves 639 that are slidably connected to the outer surface of the first connecting rod 633. The inner surfaces of the two sliding grooves 639 are fixedly connected to soft cloth 638 that are fixedly connected to the outer surface of the first connecting rod 633. The outer surface of the connecting block 631 is fixedly connected to the inner surface of the connecting plate 68.

[0039] For further details, please refer to [link / reference]. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the drive mechanism 62 includes a dual-axis motor 621 fixedly connected to the left end of the first rotating rod 61 located at the rear. The right end of the dual-axis motor 621 is fixedly connected to the left end of the device housing 1. A transmission wheel 622 is fixedly connected to the middle of the outer surface of each of the two first rotating rods 61. Cables 623 are symmetrically wound around the outer surfaces of the two transmission wheels 622. A slider 624 is fixedly connected to the lower part of the inner surface of the T-shaped hole 67.

[0040] During implementation, the inner surface of the rain cover body 5 is placed on two support plates 637. At this time, the right output end of the dual-axis motor 621 is activated, driving the first rotating rod 61 to rotate, which in turn drives the cable 623 to move backward. This causes the slider 624 on the cable 623 to slide on the inner surface of the T-shaped hole 67, thereby driving the support plates 637 to move backward. Under the pressure of the pressing plate 66, the round block 634 slides on the outer surface of the pressing plate 66. When the round block 634 moves to the convex surface of the pressing plate 66, the round block 63... 4 will move away from each other, pushing the first connecting rod 633 to slide on the inner surface of the connecting plate 68, so that the first connecting rod 633 pushes the circular plate rectangular rod 632 to slide on the inner surface of the connecting block 631, squeezing the first spring 636 into a compressed state. At the same time, the rubber block on the support plate 637 can be pressed tightly against the left and right sides of the inner surface of the rain cover body 5, so that the rain cover body 5 can be clamped by the inner surface bracket, so that the rain cover can be transported back and forth, and automatically perform clamping operations during the transport process, improving the working efficiency of the drilling operation.

[0041] For further details, please refer to [link / reference]. Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 In this embodiment, the ejection mechanism 64 includes a rectangular plate 641 that is fixedly connected to the left and right sides of the inner surface of the device housing 1. The lower end of the slider 624 is in close contact with the upper end of the rectangular plate 641. A pressing groove 642 is provided in the middle of the upper end of the rectangular plate 641. A pressing wheel 643 is slidably connected to the lower part of the inner surface of the pressing groove 642. A round rod 644, which is fixedly connected to the upper end of the pressing wheel 643, is slidably connected to the middle of the upper end of the slider 624 and extends to the lower end of the slider 624. An ejection block 645, which is slidably connected to the inner surface of the connecting plate 68, is fixedly connected to the upper end of the round rod 644. A second spring 646 is sleeved on the outer surface of the round rod 644. The two ends of the second spring 646 are fixedly connected to the lower end of the ejection block 645 and the upper end of the slider 624, respectively.

[0042] During implementation, after the drilling of the rain cover body 5 is completed, the rain cover body 5 continues to move along with the support plate 637. Since the connecting plate 68 and the connecting block 631 are fixedly connected, the connecting plate 68 also moves along with the connecting block 631, thereby driving the round rod 644 to move. This allows the extrusion roller 643 at the lower end of the round rod 644 to slide on the inner surface of the extrusion groove 642. When the clamping mechanism 63 moves to the rear of the T-shaped hole 67, the round block 634 will move to the concave surface of the extrusion plate 66. The round block 634 will be compressed by the first spring 636. The force resets the circular plate, causing the rectangular rod 632 to move the support plate 637 away from the inner surface of the rain cover body 5. This prevents the rain cover body 5 from being clamped by the inner support, and the extrusion wheel 643 moves to the rear of the lower part of the inner surface of the extrusion groove 642 and is lifted. This causes the extrusion wheel 643 to push the circular rod 644 to slide on the inner surface of the slider 624, pushing the ejector block 645 to eject the rain cover body 5. At the same time, the second spring 646 is in a stretched state, allowing the perforated rain cover body 5 to be ejected from the clamping mechanism 63, thereby improving the work efficiency of the perforation operation.

[0043] For further details, please refer to [link / reference]. Figure 3 , Figure 5 , Figure 7 and Figure 9 In this embodiment, the protective mechanism 65 includes a protective cloth 653 fixedly connected to the front end of the connecting plate 68. A circular groove 654 is provided on the front part of the inner surface of the T-shaped hole 67. A fixing rod 651 is fixedly connected to the left and right parts of the inner surface of the circular groove 654. A spring 652 fixedly connected to the front end of the protective cloth 653 is fixedly connected to the outer surface of the fixing rod 651.

[0044] As can be seen from the above, since the rain cover body 5 will generate debris during the drilling process, the left and right movement of the connecting plate 68 will pull the protective cloth 653 to move. Under the deformation of the spring 652, the protective cloth 653 can always be kept taut. As a result, the debris generated during the drilling process of the rain cover body 5 will not enter the inner cavity of the device housing 1 through the T-shaped hole 67, thereby avoiding affecting the normal operation of other components.

[0045] Example 2: Based on Example 1, this example adds a deburring component 7 to deburr the inner surface of the perforated rain cover body 5, thereby achieving the purpose of deburring the inner wall of the perforated rain cover body.

[0046] Specifically, in order to deburr the inner wall of the rain cover body 5 after drilling, please refer to... Figure 1 , Figure 3 , Figure 10 , Figure 11 and Figure 12 In this embodiment, the deburring assembly 7 includes a concave plate 71 fixedly connected to the front of the upper end of the device housing 1, a cleaning mechanism 72 is provided at the lower end of the concave plate 71, a lubrication mechanism 73 is provided at the middle of the left end of the device housing 1, and a deburring mechanism 74 is provided at the rear of the upper end of the device housing 1.

[0047] For further details, please refer to [link / reference]. Figure 1 , Figure 3 , Figure 10 , Figure 11 and Figure 12 In this embodiment, the cleaning mechanism 72 includes two squeezing rollers 722. Two circular grooves 721 are linearly distributed at the lower end of the concave plate 71. The inner surfaces of the two circular grooves 721 are rotatably connected to the two squeezing rollers 722 respectively. Two square grooves 723 are linearly distributed at the lower end of the concave plate 71. A first sponge block 724 is attached to the inner surface of the front square groove 723. A third spring 725 is symmetrically fixed to the lower end of the concave plate 71 behind the first sponge block 724. The lower ends of the two third springs 725 are fixedly connected to a wiping cloth 726.

[0048] During implementation, as the rain cover body 5 is conveyed backward by the clamping mechanism 63, the rain cover body 5 is first squeezed by the extrusion roller 722. This can prevent the upper end of the rain cover body 5 from tilting during the internal support clamping process, so that the upper end of the rain cover body 5 can be at the same horizontal height, ensuring that the upper end of the rain cover body 5 can be perpendicular to the punching mechanism 4 in the subsequent process.

[0049] Secondly, during the conveying process, it first passes through the first sponge block 724, which can absorb the residual oil on the upper part of the rain cover body 5. Then it passes through the wiping cloth 726. Under the reaction force of the third spring 725, the wiping cloth 726 can always stick tightly to the upper part of the rain cover body 5, so that the upper part of the rain cover body 5 is cleaned again to remove dust and oil. This ensures that no oil or dust remains on the upper part of the rain cover body 5, thus avoiding affecting the quality of the drilling.

[0050] For further details, please refer to [link / reference]. Figure 1 , Figure 3 , Figure 6 and Figure 11 In this embodiment, the lubrication mechanism 73 includes a placement box 731 fixedly connected to the middle of the left end of the device housing 1. The left output end of the dual-axis motor 621 is fixedly connected to a second rotating rod 732 via a coupling. A first one-way bearing 733 is fixedly connected to the right side of the outer surface of the second rotating rod 732. A transmission rod 7311 is rotatably connected to the left end of the device housing 1. A first pulley group 734 is fixedly connected to the outer surface of the first one-way bearing 733 and the outer surface of the transmission rod 7311. The left side of the outer surface of the transmission rod 7311 is fixedly connected to... There is a cam 735, and a second connecting rod 736 is rotatably connected to the left side of the outer surface of the cam 735. A piston 737 is rotatably connected to the inner surface of the second connecting rod 736 and slidably connected to the inner surface of the placement box 731. A connecting pipe 738 is fixedly connected to the left side of the inner surface of the rear square groove 723 through the front part of the inner surface of the placement box 731. A second sponge block 739 is pasted on the inner surface of the rear square groove 723. A one-way valve 7310 is fixedly connected to the lower front side of the inner surface of the placement box 731 and the connecting pipe 738.

[0051] During implementation, the left output end of the dual-axis motor 621 is started and rotated forward, driving the second rotating rod 732 to rotate. Under the action of the first one-way bearing 733, the first pulley group 734 is driven, which in turn causes the transmission rod 7311 to rotate, driving the cam 735 to rotate. The rotation of the cam 735 can drive the second connecting rod 736 to rotate, allowing the piston 737 to slide on the inner surface of the placement box 731. This allows the lubricating oil stored in the upper space of the inner surface of the placement box 731 to pass through the one-way valve 7310. The drill bit enters the lower space inside the inner surface of the placement box 731. At this time, under the squeezing action of the piston 737, the lubricating oil can enter the connecting pipe 738 and then enter the second sponge block 739. When the second sponge block 739 passes over the rain cover body 5, it applies lubricating oil to the upper part of the rain cover body 5. The lubricating properties of the lubricating oil can reduce the friction between the drill bit and the material of the rain cover body 5, making the drilling process smoother, reducing the heat and wear generated by friction, protecting the integrity of the rain cover and the drill bit, and reducing the generation of burrs.

[0052] The one-way valve 7310 mentioned above is a mature control device and a mature control method in the prior art. This solution utilizes its ability to control the direction of fluid movement, and its structure and principle will not be elaborated further.

Figure 1 , Figure 3 , Figure 6 , Figure 11 and Figure 12 In this embodiment, the deburring mechanism 74 includes a cylinder 741 fixedly connected to the rear left side of the upper end of the device housing 1. A hollow plate 742 is fixedly connected to the upper end of the cylinder 741. A worm gear 748 is rotatably connected to the left end of the hollow plate 742 and extends to the right end of the hollow plate 742. A grinding block 7410 is rotatably connected to the lower right side of the inner surface of the hollow plate 742 and extends to the lower end of the hollow plate 742. A meshing connection between the grinding block 7410 and the worm gear 748 is fixedly connected to the upper part of the outer surface of the grinding block 7410. The worm gear 749 is fixedly connected to the upper left rear part of the device housing 1. The inner surface of the L-shaped plate 747 is rotatably connected to the third rotating rod 745. The left part of the outer surface of the second rotating rod 732 is fixedly connected to the second one-way bearing 743. The outer surface of the second one-way bearing 743 and the left part of the outer surface of the third rotating rod 745 are jointly fixedly connected to the second pulley group 744. The right part of the outer surface of the third rotating rod 745 and the left end of the worm gear 749 are jointly fixedly connected to the gear group 746.

[0054] During implementation, after the rain cover body 5 is drilled, it moves to a set position and activates cylinder 741. Cylinder 741 drives the hollow plate 742 downward, allowing the grinding block 7410 to enter the inner wall of the hole. Simultaneously, the planar gear on the worm 748 meshes with the planar gear on the third rotating rod 745, activating the left output end of the dual-axis motor 621 to rotate in the opposite direction, causing the second rotating rod 732 to rotate again. Under the action of the second one-way bearing 743, the transmission operation is carried out through the second pulley group 744, causing the third rotating rod 745 to rotate. Then, through the transmission of the gear group 746, the worm 748 is driven to rotate. Under the action of meshing connection, the worm wheel 749 drives the grinding block 7410 to perform grinding operations on the inner surface of the hole, thereby reducing burrs on the inner surface of the hole and improving the drilling quality and deburring efficiency.

[0055] The aforementioned dual-axis motor 621 is a mature drive technology device in the prior art and a mature drive technology means in the prior art. This solution utilizes its ability to rotate independently on both sides, and the number of rotations on both sides can be adjusted and controlled separately. It can stop in time after rotating to the set number of rotations.

[0056] The first one-way bearing 733 and the second one-way bearing 743 mentioned above are mature one-way rotating parts in the prior art. This solution utilizes their function of being able to rotate freely in one direction and being locked in the other direction. In this solution, the locking directions of the first one-way bearing 733 and the second one-way bearing 743 are opposite. Their structure and principle will not be described further.

[0057] The first pulley group 734 and the second pulley group 744 mentioned above are both composed of two rollers and a belt.

[0058] The gear set 746 mentioned above is composed of two planar gears. In this scheme, the planar gear on the worm 748 and the planar gear on the third rotating rod 745 can still mesh again after moving away from each other.

[0059] Workflow: During use, the rain cover body 5 is placed on the clamping mechanism 63. At this time, under the action of the drive mechanism 62, the rain cover body 5 is driven to move backward. Under the action of the extrusion plate 66, the clamping mechanism 63 can clamp and fix the rain cover body 5. At the same time, under the action of the extrusion roller 722 in the cleaning mechanism 72, the upper end of the rain cover body 5 is kept at the same level. During the movement, the cleaning mechanism 72 cleans the oil and dust on the upper end of the rain cover body 5. Then, the lubrication mechanism 73 applies lubricating oil to the upper end of the rain cover body 5. The drilling mechanism 4 performs the drilling operation. After the drilling is completed, the deburring mechanism 74 removes the burrs on the inner wall of the hole. Finally, the ejection mechanism 64 ejects the rain cover body 5 from the clamping mechanism 63.
