Description

Technical Field

[0001] This utility model relates to the field of arc-extinguishing grid technology, specifically to an arc-extinguishing grid assembly tooling. Background Technology

[0002] Arc extinguishing grids are key components used in electrical equipment, especially circuit breakers and contactors. Their main function is to quickly extinguish electric arcs during current interruption, prevent arc damage to equipment, and ensure the safe and reliable operation of circuits.

[0003] In the prior art, a patent specification with publication number CN219759413U discloses an automatic assembly device for arc-extinguishing plates. The device includes an assembly base, a conveyor belt on the top surface of the assembly base, a support frame on one side of the top surface of the assembly base relative to the conveyor belt, a lifting motor on the top surface of the support frame, a lifting screw at the output end of the lifting motor, and a mounting platform on the side of the lifting screw. By arranging the operating frame in a regular hexagonal structure and placing corresponding electromagnetic coils on the inner side of the operating frame, the arc-extinguishing plates can be attracted into the placement slots when the electromagnetic coils are energized. A rotary motor drives the arranged arc-extinguishing plates to rotate until their bottom faces the conveyor belt. After power is cut off, they fall into the red steel paper clips on the top surface of the conveyor belt. A squeezing cylinder drives a punch head to strike the red steel paper, connecting the ten arc-extinguishing plates into one unit, thus completing the operation. This simplifies the assembly process of the arc-extinguishing grid and reduces the failure rate during assembly.

[0004] However, the above-mentioned patent still has the following problems: When assembling the arc-extinguishing grid, the spacing between the placement slots of the above-mentioned automatic assembly equipment for arc-extinguishing grid is fixed and cannot be adjusted, so it can only adapt to the installation of arc-extinguishing lamps and corresponding red steel paper under one working condition. Since different working conditions require different installation densities of arc-extinguishing grids, the above-mentioned device cannot adapt well when the spacing between the arc-extinguishing grids to be placed increases or decreases, which reduces the practicality of the entire device and reduces the assembly efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an assembly tooling for arc-extinguishing grid plates to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an arc-extinguishing grid assembly fixture, comprising: a rotating shaft, both ends of which are rotatably sleeved in a fixed plate, a connecting block fixedly sleeved in the middle of the rotating shaft, a U-shaped frame fixedly connected to the upper and lower sides of the connecting block, a connecting shaft rotatably sleeved inside the U-shaped frame, a rotating roller fixedly sleeved on the connecting shaft, and a spiral groove formed on the outer ring surface of the rotating roller.

[0007] The spiral groove is slidably connected to one end of the sliding pin, and the other end of the sliding pin is fixedly sleeved on one side of the support plate. A support rod is fixedly sleeved on the other side of the support plate. One end of the support rod is fixedly connected to the placement frame. An electromagnetic coil is installed inside the placement frame. The support plate is slidably sleeved on the limiting rod, and the limiting rod is fixedly connected to the U-shaped frame.

[0008] Preferably, an adjusting motor is fixedly connected to the inner side wall of the U-shaped frame, and the output end of the adjusting motor passes through the U-shaped frame and is fixedly connected to the active meshing wheel.

[0009] Preferably, a driven meshing wheel is provided on one side of the active meshing wheel, and the active meshing wheel and the driven meshing wheel are driven by meshing belt. The driven meshing wheel is fixedly sleeved on the end of the connecting shaft near the adjusting motor.

[0010] Preferably, a controller is fixedly installed on the top of one of the fixed plates, and a drive motor is fixedly installed on one side of the other fixed plate. Both the adjusting motor and the drive motor are electrically connected to the controller.

[0011] Preferably, the output end of the drive motor is fixedly connected to one end of the worm, the other end of the worm is rotatably sleeved on one end of the support base, the other end of the support base is fixedly connected to the fixed plate, and a worm wheel is engaged on one side of the worm.

[0012] Preferably, the worm gear is fixedly sleeved on the end of the rotating shaft near the drive motor, a fixed frame is provided on one side of the drive motor, and extrusion cylinders are fixedly connected to both sides of the inner wall of the fixed frame. A punching head is fixedly connected to the output end of the extrusion cylinder, and a conveyor belt is installed between the two extrusion cylinders.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When the assembly density of the required arc-extinguishing grid needs to be adjusted, the rotation of the connecting shaft is indirectly driven by the motor, which in turn drives the rotating roller fixedly mounted on it to rotate. The rotating roller drives the sliding pin to slide within the spiral groove on its surface, which in turn drives the support plate fixedly connected to it to move. The support plate slides laterally under the limit of the limiting rod, so the support plate drives the support rod to move synchronously, which in turn drives the placement frame to move. Thus, the distance between the placement frames can be adjusted by the lateral sliding of the support plate on the limiting rod, which can adapt to the assembly of arc grids with different densities, improve the flexibility and practicality of the whole device, and improve the processing efficiency.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: an arc-extinguishing grid assembly fixture, comprising: a rotating shaft 1, both ends of which are rotatably sleeved in a fixed plate 17, a bearing seat fixedly installed on the fixed plate 17, the rotating shaft 1 being rotatably sleeved in the bearing seat to improve the rotational stability of the rotating shaft 1, a connecting block 2 fixedly sleeved in the middle of the rotating shaft 1, U-shaped frames 3 fixedly connected to the upper and lower sides of the connecting block 2, a connecting shaft 4 rotatably sleeved in the U-shaped frame 3, a rotating roller 5 fixedly sleeved on the outer ring surface of the connecting shaft 4, a spiral groove 6 opened on the outer ring surface of the rotating roller 5, the spiral groove 6 being slidably connected to one end of a sliding pin 7, the other end of the sliding pin 7 being fixedly sleeved on one side of a support plate 8, a support rod 9 fixedly sleeved on the other side of the support plate 8, one end of the support rod 9 being fixedly connected to a placement frame 10, an electromagnetic coil 11 being installed in the placement frame 10, the support plate 8 being slidably sleeved on a limiting rod 12, and the limiting rod 12 being fixedly connected to the U-shaped frame 3.

[0024] The rotating shaft 1 is stably supported by the fixing plate 17 to ensure its stability during rotation. An electromagnetic coil 11 is installed at the bottom of the placement frame 10. During arc-extinguishing grid assembly, the operator places the arc-extinguishing plate inside the placement frame 10, which is located at the top of the fixing plate 17. When the electromagnetic coil 11 is energized, the arc-extinguishing grid is attracted to the inside of the placement frame 10. The rotation of the rotating shaft 1 drives the connecting block 2 to rotate, which in turn drives the U-shaped frame 3 to rotate. This indirectly causes the arranged arc-extinguishing grid to rotate so that its bottom faces the conveyor belt 26, facilitating subsequent assembly between the arc-extinguishing grid and the red steel cardboard. When the required arc-extinguishing grid assembly is completed... When the density needs to be adjusted, the rotation of the drive connecting shaft 4 drives the rotating roller 5 fixedly mounted on it to rotate. The rotating roller 5 drives the sliding pin 7 to slide inside the spiral groove 6 opened on its surface, which in turn causes the sliding pin 7 to drive the support plate 8 fixedly connected to it to move. The support plate 8 slides laterally under the limit of the limiting rod 12, so the support plate 8 drives the support rod 9 to move synchronously, which in turn drives the placement frame 10 to move. Thus, the distance between the placement frames 10 can be adjusted by the lateral sliding of the support plate 8 on the limiting rod 12, which can adapt to the assembly of arc-shaped grid sheets of different densities, improve the flexibility and practicality of the whole device, and improve the processing efficiency.

[0025] Example 2: Based on Example 1, an adjusting motor 13 is fixedly connected to the inner wall of the U-shaped frame 3. The output end of the adjusting motor 13 passes through the U-shaped frame 3 and is fixedly connected to the active meshing wheel 14. The U-shaped frame 3 is symmetrically arranged about the center plane of the connecting block 2. The U-shaped frame 3 provides fixed support for the adjusting motor 13. A driven meshing wheel 15 is provided on one side of the active meshing wheel 14. The active meshing wheel 14 and the driven meshing wheel 15 are meshed and driven by a meshing belt 16. The driven meshing wheel 15 is fixedly sleeved on the end of the connecting shaft 4 near the adjusting motor 13. The active meshing wheel 14 meshes and drives the driven meshing wheel 15 through the meshing belt 16, thereby driving the transmission through meshing. This makes the transmission process more stable, prevents slippage, and achieves precise control, thus facilitating precise adjustment to adapt to the installation of different sealing arc-extinguishing grid plates.

[0026] When assembling arc-extinguishing grid sheets of different densities, the regulating motor 13 is started. Under the operation of the regulating motor 13, the active meshing wheel 14 fixedly installed at its output end rotates. The active meshing wheel 14 drives the driven meshing wheel 15 to rotate through the meshing drive 16. The driven meshing wheel 15 then drives the connecting shaft 4 fixedly sleeved inside it to rotate under the limit of the U-shaped frame 3. The connecting shaft 4 drives the rotating roller 5 to rotate. Under the constraint of the spiral groove 6 opened on the rotating roller 5, the sliding pin 7 is driven to slide in it. The sliding pin 7 drives the support plate 8 to move. The support plate 8 is slidably sleeved on the limiting rod 12. Thus, the support plate 8 slides laterally on the limiting rod 12. The support plate 8 drives the support rod 9 to move at the same time. The support rod 9 drives the placement frame 10 to move. Then, the distance between the placement frames 10 can be adjusted by the sliding distance of the sliding pin 7 in the spiral groove 6. This can adapt to the assembly of arc-shaped grid sheets of different densities, improve the flexibility and practicality of the whole device, and improve the processing efficiency.

[0027] Example 3: Based on Example 2, a controller 18 is fixedly installed on the top of one of the fixed plates 17, and a drive motor 19 is fixedly installed on one side of the other fixed plate 17. Both the adjusting motor 13 and the drive motor 19 are electrically connected to the controller 18. The controller 18 controls the drive motor 19 and the adjusting motor 13, thereby facilitating the orderly operation of the entire device. The output end of the drive motor 19 is fixedly connected to one end of the worm gear 20, and the other end of the worm gear 20 is rotatably sleeved on one end of the support base 21. The other end of the support base 21 is fixedly connected to the fixed plate 17. A worm wheel 22 meshes with one side of the worm gear 20. One end of the worm gear 20 is supported, and the other end of the worm gear 20 is fixedly connected to the output end of the drive motor 19. The worm gear 20 meshes with the worm wheel 22, and the worm wheel 22 is fixedly sleeved on the end of the rotating shaft 1 near the drive motor 19. A fixed frame 23 is provided on one side of the drive motor 19. Extrusion cylinders 24 are fixedly connected to both sides of the inner wall of the fixed frame 23. A punch head 25 is fixedly connected to the output end of the extrusion cylinder 24. A conveyor belt 26 is installed between the two extrusion cylinders 24. The extrusion cylinders 24 are stably supported by the fixed frame 23. The extrusion cylinders 24 are connected to an external air source and are electrically connected to the controller 18.

[0028] The controller 18 starts the drive motor 19 to rotate, which in turn drives the worm 20 to rotate. The worm 20 meshes with the worm wheel 22, causing the worm wheel 22 to drive the rotating shaft 1, which is fixedly sleeved inside it, to rotate. The rotating shaft 1 rotates under the limit of the fixed plate 17. The rotating shaft 1 then drives the connecting block 2 to rotate, and the connecting block 2 in turn drives the U-shaped frame 3 to rotate. Through the meshing transmission between the worm wheel 22 and the worm 20, the rotating shaft 1 has a certain self-locking ability during rotation, thereby improving the rotation of the U-shaped frame 3. To ensure rotational stability, the U-shaped frame 3 indirectly rotates the arranged arc-extinguishing grids to the bottom facing the conveyor belt 26. At this time, the electromagnetic coil 11 is de-energized, causing the arc-extinguishing grids to fall into the red steel paper card on the top surface of the conveyor belt 26. The controller 18 controls the operation of the extrusion cylinder 24, causing the output ends of the two extrusion cylinders 24 to move towards each other, thereby driving the punch head 25 to strike the red steel paper, so that the edge of the arc-extinguishing grid passes through the red steel paper. The snap-fit ​​of the red steel paper connects the arranged arc-extinguishing grids into one piece.
