Abstract

This application relates to a tooling for assisting in the assembly of a vacuum interrupter. The tooling includes a transport cart, a support frame, and a lifting drive mechanism. The transport cart has a bearing surface for supporting a ceramic shell within the vacuum interrupter. A movable conductive rod is mounted on the ceramic shell, and a contact seat is located at the top of the movable conductive rod, with an elastic element abutting against it. The support frame has a first slot adapted to the outer periphery of the movable conductive rod for engaging with it. The fixed end of the lifting drive mechanism is located on the support frame, and its output end is vertically positioned and abuts against the elastic element in the contact seat.

Description

Technical Field

[0001] This application relates to the field of auxiliary tooling technology, and in particular to a tooling for assisting in the assembly of a vacuum interrupter. Background Technology

[0002] Vacuum interrupters, also known as vacuum switch tubes, are core components of medium- and high-voltage power switches. Their main function is to rapidly extinguish the arc and suppress current after the power supply to the medium- and high-voltage circuit is cut off, thanks to the excellent insulation of the vacuum inside the tube, thus preventing accidents and unforeseen events. Vacuum interrupters are mainly used in power transmission and distribution control systems, and also in power distribution systems in metallurgy, mining, petroleum, chemical, railway, broadcasting, communications, and industrial high-frequency heating.

[0003] A vacuum interrupter includes a contact seat, a ceramic shell, a moving conductive rod, and an elastic element. One end of the moving conductive rod is sealed to the ceramic shell, while the other end is detachably connected to the contact seat. The elastic element is compressed within the contact seat. Currently, fasteners are typically used to achieve the detachable connection between the moving conductive rod and the contact seat, and a guide is used to compress the elastic element. Specifically, during the detachable installation of the moving conductive rod and the contact seat, a worker needs to use pliers to hold the moving conductive rod in place before screwing the fasteners into the contact seat and the moving conductive rod to prevent the moving conductive rod from rotating during installation. When compressing the elastic element, the guide is placed above the elastic element. The worker then passes a connecting rod through the pin hole in the guide and manually presses the connecting rod until the elastic element is compressed to a preset position, thus achieving compression of the elastic element.

[0004] During the installation process described above, workers need to use hand-held pliers to fix the moving conductive rod, which is inefficient and labor-intensive. Workers also need to manually press the connecting rod to compress the spring, making it difficult to ensure that each press is a vertical downward force. When the force deviates, it can easily generate radial force on the moving conductive rod, thus causing irreversible damage to the ceramic shell. Summary of the Invention

[0005] Therefore, it is necessary to provide a tooling for assisting in the assembly of vacuum interrupters, addressing the problems of low efficiency and easy damage to the ceramic shell in the vacuum interrupter due to improper operation during installation.

[0006] A tooling for assisting in the assembly of a vacuum interrupter, the tooling comprising a transport vehicle, a support frame, and a lifting drive mechanism, wherein:

[0007] The transport vehicle has a bearing surface for supporting the ceramic shell in the vacuum interrupter. A movable conductive rod is provided on the ceramic shell, and a contact seat is provided at the top of the movable conductive rod. An elastic element is provided in the contact seat to abut against it.

[0008] The support frame is provided with a first slot that is adapted to the outer periphery of the movable conductive rod, and the first slot is used to engage with the movable conductive rod.

[0009] The fixed end of the lifting drive mechanism is disposed on the support frame, and the output end of the lifting drive mechanism is vertically disposed and used to abut against the elastic element in the contact seat.

[0010] The aforementioned tooling for assisting in the assembly of the vacuum interrupter uses a transport trolley to carry the moving conductive rod. The support frame has a first slot that matches the outer circumference of the moving conductive rod. During use, the transport trolley can move the moving conductive rod into the first slot to secure it. This prevents the moving conductive rod from rotating during the subsequent screwing of fasteners into the contact seat and the moving conductive rod, eliminating the need for workers to use hand clamps to fix the moving conductive rod, thus improving work efficiency and reducing labor costs. Furthermore, the vertically positioned output end of the lifting drive mechanism abuts against the elastic element in the contact seat. The lifting drive mechanism compresses the elastic element, ensuring both a constant force applied to the elastic element and that the force is applied vertically downwards. This prevents the force from shifting and causing radial force on the moving conductive rod, which could damage the ceramic shell.

[0011] In one embodiment, the moving conductive rod has a first end that extends beyond the ceramic shell, and the first end has an annular groove along its circumference to form a snap-fit ​​neck, the first snap-fit ​​groove being used to snap into the snap-fit ​​neck.

[0012] In one embodiment, the support frame is further provided with a second slot spaced apart from the first slot. The second slot is adapted to the outer periphery of the first end and is used to engage with the first end.

[0013] In one embodiment, the support frame includes a support plate and at least one column, the support plate is connected to the column, and an accommodating space is formed between the support plate and the column. The support plate has a first slot and a second slot on its side.

[0014] In one embodiment, when the second slot engages with the first end, the bottom end of the contact seat near the moving conductive rod abuts against the top end of the support plate.

[0015] In one embodiment, the support frame further includes a positioning frame disposed on the side of the bearing plate away from the column, the fixed end of the lifting drive mechanism is disposed in the positioning frame, and the output end of the lifting drive mechanism passes through the positioning frame and is positioned opposite to the second slot located in the positioning frame.

[0016] In one embodiment, the support frame further includes an abutment plate disposed on the support plate and located within the positioning frame.

[0017] In one embodiment, the number of columns is at least four, and the four columns are located at the four corners of the support plate.

[0018] In one embodiment, a first reinforcing rib is provided between two adjacent columns.

[0019] In one embodiment, the lifting drive mechanism includes a lifting drive component and a pressure rod connected to the output end of the lifting drive component. The pressure rod is vertically arranged and used to abut against the elastic element in the contact seat. Attached Figure Description

[0037] See Figure 1 As shown, Figure 1 This is a schematic diagram of the vacuum interrupter 20 provided in this application. In related technologies, the vacuum interrupter 20 includes a contact seat 21, a ceramic shell 22, a moving conductive rod 23, and an elastic element 24. One end of the moving conductive rod 23 is sealed to the ceramic shell 22, and the other end is detachably connected to the contact seat 21. The elastic element 24 is compressed within the contact seat 21. In actual installation, fasteners 25 are typically used to achieve the detachable connection between the moving conductive rod 23 and the contact seat 21, and guide elements 26 are used to compress the elastic element 24. The fasteners 25 can be bolts, screws, or other fastening components.

[0038] Specifically, when the movable conductive rod 23 and the contact seat 21 are detachably installed, the worker needs to use pliers to hold the movable conductive rod 23 in place, and then screw the fastener 25 into the contact seat 21 and the movable conductive rod 23 to prevent the movable conductive rod 23 from rotating during installation. When compressing the elastic element 24, the guide 26 is placed above the spring, and then the worker needs to pass the connecting rod through the pin hole 27 of the guide 26, and then manually press the connecting rod until the elastic element 24 is compressed to the preset position to achieve the compression of the elastic element 24.

[0039] However, during the installation process described above, workers need to use hand-held pliers to fix the moving conductive rod 23, which is inefficient and has high labor costs. Workers also need to manually press the connecting rod to compress the spring, making it difficult to ensure that each press is a vertical downward force. When the force deviates, it can easily generate radial force on the moving conductive rod 23, thereby causing irreversible damage to the ceramic shell 22.

[0040] Based on this, see Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the structure for assisting in the assembly of the vacuum interrupter 20 according to an embodiment of this application. Figure 3 for Figure 2 An enlarged structural schematic diagram at point A. An embodiment of this application provides a tooling 10 for assisting in the assembly of a vacuum interrupter 20, comprising a transport cart 100, a support frame 200, and a lifting drive mechanism 300. The transport cart 100 has a bearing surface 111 for supporting the ceramic shell 22 in the vacuum interrupter 20. A movable conductive rod 23 is disposed on the ceramic shell 22, and a contact seat 21 is disposed at the top of the movable conductive rod 23. An elastic element 24 is provided in the contact seat 21 for contact. In a specific configuration, the transport cart 100 includes a transport base 110 and rollers 120 mounted on the transport base 110. Multiple rollers 120 are spaced apart on the transport base 110. Specifically, this application preferably uses four rollers 120, which are disposed at the four corners of the transport base 110. In actual use, the ceramic shell 22 and the moving conductive rod 23, which are set on the bearing surface 111 of the transport seat 110, are transported to the set position by the rollers 120.

[0041] The support frame 200 has a first slot 211 that matches the outer periphery of the movable conductive rod 23. The first slot 211 is used to engage with the movable conductive rod 23. In actual use, the transport vehicle 100 transports the movable conductive rod 23 to the first slot 211 for engagement, that is, the movable conductive rod 23 is fixed to the support frame 200 through the first slot 211. The top of the movable conductive rod 23 is provided with a contact seat 21. At this time, the fastener 25 is screwed into the contact seat 21 and the movable conductive rod 23. The first slot 211 prevents the movable conductive rod 23 from rotating, thereby eliminating the traditional method of fixing the movable conductive rod 23 by hand clamps, improving work efficiency and reducing labor costs.

[0042] The fixed end of the lifting drive mechanism 300 is mounted on the support frame 200, and the output end of the lifting drive mechanism 300 is vertically positioned to abut against the elastic element 24 in the contact seat 21. Through this configuration, the lifting drive mechanism 300 applies force to the elastic element 24 to achieve deformation of the elastic element 24, ensuring a constant and controllable force. Furthermore, the vertical positioning of the output end ensures that the force applied to the elastic element 24 is vertically downward, preventing the force from shifting and generating radial force on the moving conductive rod 23, thus avoiding damage to the ceramic shell 22.

[0043] To better hold the movable conductive rod 23 in the first slot 211, in a preferred embodiment, the movable conductive rod 23 has a first end 28 extending beyond the ceramic shell 22. The first end 28 has an annular groove along its circumference to form a snap-fit ​​neck 29. The first slot 211 is used to snap into the snap-fit ​​neck 29. It should be noted that, to ensure the strength of the snap-fit ​​neck 29, the annular groove should not be too deep. Therefore, the contact area between the groove wall of the first slot 211 and the groove wall of the annular groove is limited, resulting in a limited clamping force of the first slot 211 on the movable conductive rod 23, making it difficult to compress the elastic element 24 with excessive elasticity. Based on this, to solve the above problems, the support frame 200 also has a second slot 212 spaced apart from the first slot 211. The second slot 212 is adapted to the outer periphery of the first end 28 and is used to snap into the first end 28.

[0044] With the above configuration, in actual use, the transport vehicle 100 first transports the movable conductive rod 23 to the first slot 211, so that the first slot 211 engages with the snap-fit ​​neck 29; then the fastener 25 is screwed into the contact seat 21 and the movable conductive rod 23; then the transport vehicle 100 transports the movable conductive rod 23 to the second slot 212, so that the second slot 212 engages with the first end 28 of the movable conductive rod 23, increasing the contact area between the second slot 212 and the first end 28, and more firmly fixing the movable conductive rod 23, which facilitates the subsequent compression of the elastic element 24.

[0045] In order for the transport vehicle 100 to conveniently deliver the moving conductive rod 23 to the first groove and the second groove, specifically, the support frame 200 includes a bearing plate 210 and at least one column 220. In specific configuration, the number of columns 220 can be 2, 4, 6 or more. The bearing plate 210 is connected to the column 220. The height of the column 220 is the sum of the height of the transport vehicle 100 and the height of the ceramic shell 22. An accommodating space 230 is formed between the bearing plate 210 and the column 220. A first slot 211 is provided on the side of the bearing plate 210 to facilitate the ceramic shell 22 on the transport vehicle 100 and at least part of the transport vehicle 100 entering the accommodating space 230 during transport. The snap-fit ​​neck 29 at the top of the ceramic shell 22 is at the same height as the first slot 211 for snap-fit.

[0046] In one embodiment of this application, the support plate 210 is further provided with a second slot 212 on its side. A clamping pad 240 is provided on the top of the support plate 210 along the circumferential contour of the second slot 212. The clamping pad 240 is used to clamp the first end 28. In a specific configuration, the second slot 212 is preferably a U-shaped slot, and the clamping pad 240 is also correspondingly designed as a U-shape. It should be noted that the shape of the second slot 212 is not limited to the above-mentioned U-shape, and can be any geometric shape such as an ellipse or rectangle with one end open. Correspondingly, the shape of the clamping pad 240 can also be any geometric shape with one end open.

[0047] To better bear the downward force applied by the lifting drive mechanism 300, more specifically, when the second slot 212 engages with the first end 28, the bottom end of the contact seat 21 near the moving conductive rod 23 abuts against the top end of the bearing plate 210. In a specific configuration, the bottom end of the contact seat 21 near the moving conductive rod 23 abuts against the top end of the clamping pad 240. To facilitate the abutment between the bottom end of the contact seat 21 and the top end of the clamping pad 240, a limiting groove is also provided on the bearing surface 111 of the transport seat 110. The ceramic shell 22 is disposed in the limiting groove to reduce the height of the ceramic shell 22 exceeding the transport seat 110, so that the first end 28 is compatible with the second slot 212 and the clamping pad 240.

[0048] To facilitate the fixing of the lifting drive mechanism 300 and ensure that the output end of the lifting drive mechanism 300 is aligned with the elastic element 24, the support frame 200 further includes a positioning frame 250. The positioning frame 250 is located on the side of the bearing plate 210 away from the column 220. The fixed end of the lifting drive mechanism 300 is located in the positioning frame 250, and the output end of the lifting drive mechanism 300 passes through the positioning frame 250 and is directly opposite the second slot 212 located within the positioning frame 250. In a specific configuration, the positioning frame 250 includes a top plate 251 and a side wall 252 located on the top plate 251. The side wall 252 and the top plate 251 form a receiving cavity 253. The fixed end of the lifting drive mechanism 300 is located on the top plate 251, and the output end of the lifting drive mechanism 300 passes through the top plate 251 and is located within the receiving cavity 253. The side wall 252 has a notch that communicates with the receiving cavity 253, so that after the second slot 212 is engaged with the first end 28, the contact seat 21 is located in the receiving cavity 253 through the notch.

[0049] With the above configuration, in actual use, the transport vehicle 100 first transports the ceramic shell 22 and the movable conductive rod 23 disposed on the ceramic shell 22 to the first slot 211, so that the first slot 211 is engaged with the snap-fit ​​neck 29; then the fastener 25 is screwed into the contact seat 21 and the movable conductive rod 23; then the ceramic shell 22 is placed in the limiting groove in the transport vehicle 100; then the transport vehicle 100 transports the movable conductive rod 23 on the ceramic shell 22 to the second slot 212, so that the second slot 212 is engaged with the first end 28 of the movable conductive rod 23; then the lifting drive mechanism 300 is started, and the output end of the lifting drive mechanism 300 descends to compress the elastic element 24 in the contact seat, thereby compressing the elastic element 24.

[0050] It should be noted that the elastic element 24 in the contact seat 21 needs to be kept in a compressed state at all times. In order to fix the compressed state of the elastic element 24 at this time, the support frame 200 further includes an abutment plate 260, which is disposed on the bearing plate 210 and located within the positioning frame 250. In specific operation, the tooling 10 used to assist in the assembly of the vacuum interrupter 20 also includes a positioning piece 400. The elastic element 24 is a spring. The positioning piece 400 passes through the gap between the contact seat 21 and the spring in the compressed state and abuts against the abutment plate 260 to ensure that the state of the spring remains unchanged. In specific configuration, the contact seat 21 has a positioning through hole that penetrates its own thickness so that the positioning piece 400 can pass through.

[0051] With the above settings, in specific operation, after the lifting drive mechanism 300 compresses the elastic element 24, the positioning piece 400 is inserted into the gap of the spring through the positioning through hole to fix the position of the spring; then the lifting drive mechanism 300 rises, allowing the output end of the lifting drive mechanism 300 to exit the contact seat 21; then the guide piece 26 is installed above the spring, and the guide piece 26 is fixed at this position by the fixing pin on the guide piece 26; then the positioning piece 400 is removed to complete the installation.

[0052] To ensure the stability of the support plate 210, the number of uprights 220 is at least four, and the four uprights 220 are located at the four corners of the support plate 210. Specifically, the support plate 210 is preferably rectangular, with four uprights 220 corresponding to the four corners. It should be noted that the support plate 210 is not limited to the rectangular structure described above; its shape can be any geometric shape such as circular, elliptical, rhomboid, or polygonal. The specific number of uprights 220 can be four, five, or more, and the uprights 220 can be distributed at intervals around the circumference of the support plate 210.

[0053] To further enhance the strength of the support frame 200, a first reinforcing rib 270 is provided between two adjacent columns 220. Specifically, a second reinforcing rib 280 is also provided between the two first reinforcing ribs 270. More specifically, the second reinforcing rib 280 is positioned at the midpoint of the first reinforcing ribs 270.

[0054] To facilitate the design of the lifting drive mechanism 300, in a preferred embodiment, the lifting drive mechanism 300 includes a lifting drive component 310 and a pressure rod 320 connected to the output end of the lifting drive component 310. The pressure rod 320 is vertically arranged, and one end of the pressure rod 320 that is vertically opposite to the lifting drive component 310 is used to abut against the elastic element 24 in the contact seat 21. With the above arrangement, the lifting drive component 310 acts on the elastic element 24 through the pressure rod 320, ensuring that the force applied to the elastic element 24 is constant. The vertical arrangement of the pressure rod 320 ensures that the force applied to the elastic element 24 is vertically downward, avoiding the situation where the force deviation generates radial force on the moving conductive rod 23, thereby causing damage to the ceramic shell 22.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
