[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-3This utility model provides an assembly and positioning device for a mine explosion-proof control box, including a base plate 6. A fixing frame 1 is bolted to the top of the base plate 6. A cylinder 2 is bolted to the top of the fixing frame 1. The piston end of the cylinder 2 passes through the fixing frame 1 and is bolted to a support frame 3. A first slide rail 8 is bolted to the bottom of the support frame 3 at its center. A second slide rail 9 is slidably connected to the bottom of the first slide rail 8 via a slide table. An electromagnet 13 (model NX-1515) is slidably connected to the bottom of the second slide rail 9 via a slide table. The top of the base plate 6 is provided with a pushing assembly for aligning the door panel with the box body. The pushing assembly includes two symmetrically arranged sliding grooves 15 at the bottom of the base plate 6. Two symmetrically arranged carriages 18 are slidably connected within the slide groove 15. A second positioning frame 7 is bolted to the top of each carriage 18. A drive assembly for moving the two carriages 18 towards each other is located at the bottom of the base plate 6. The drive assembly includes two fixing blocks 19 bolted to the bottom of the base plate 6 and located on both sides. A threaded rod 17, threadedly connected to the carriage 18, is rotatably connected to the inner side of each fixing block 19 via bearings. A servo motor for driving the threaded rod 17 to rotate along its axis is bolted to one side of one of the fixing blocks 19. When the servo motor is started, its output shaft drives the threaded rod 17 to rotate, causing the two carriages 18 to slide along the slide groove 15. The bottom of the support frame 3 is bolted to... Two symmetrically arranged guide frames 14 are provided, with a first positioning frame 4 slidably connected to the bottom of each guide frame 14. Two first telescopic rods 5 are provided between the first positioning frame 4 and the second positioning frame 7, with one end of the first telescopic rod 5 fixed to the first positioning frame 4 and the other end fixed to the second positioning frame 7. Both the first positioning frame 4 and the second positioning frame 7 have inclined surfaces 21 on their inner sides. When the drive assembly is activated, it drives two slides 18 to move inwards towards each other. The two slides 18 then drive the two second positioning frames 7 inwards, causing the inclined surfaces 21 on the inner sides of the second positioning frames 7 to contact the housing and push the housing to the middle position. Simultaneously, the first telescopic rods 5 drive the first positioning frame 4 inwards, causing the inclined surfaces 21 on the inner sides of the first positioning frame 4 to... 1. Contact the door panel and push it to the middle position. First, place the box on top of the base plate 6 and inside the pushing assembly. Then, activate the electromagnet 13 to attract the door panel to the electromagnet 13. Then, activate the pushing assembly to push the box to slide on the base plate 6 and simultaneously push the door panel to move, so that the electromagnet 13 moves along the second slide rail 9. At the same time, the second slide rail 9 moves along the first slide rail 8 to align the door panel with the box. Then, activate the cylinder 2, which drives the support frame 3 to move downward with the door panel, so that the door panel fits with the box. Then, the worker assembles them together, thus solving the problem that the manual door panel positioning method is not accurate enough and it is difficult to ensure the docking of the door panel and the box. It also greatly saves manpower consumption.

[0024] In this embodiment, two guide rods 16 are fixed to the inner sides of the two fixing blocks 19 by bolts, and the guide rods 16 are slidably connected to the slide 18. The guide rods 16 guide the slide 18, making the slide 18 slide more smoothly and preventing deviation.

[0025] In this embodiment, the top of the base plate 6 is provided with a plurality of evenly distributed grooves, and the grooves are rotatably connected with ball bearings 20 to reduce the friction of the surface of the base plate 6. By placing the box on top of the plurality of ball bearings 20, the friction between the box and the base plate 6 is greatly reduced.

[0026] In this embodiment, the bottom of the support frame 3 is provided with an elastic component for resetting the electromagnet 13. The elastic component includes multiple fixing plates 10 that are fixed to the bottom of the support frame 3 by bolts and are evenly distributed. A spring 12 is provided between the fixing plate 10 and the electromagnet 13, and one end of the spring 12 is fixed to the fixing plate 10 and the other end is fixed to the electromagnet 13. When the electromagnet 13 is not in use, the electromagnet 13 is pushed to the middle position by the cooperation of multiple springs 12, thereby realizing the rapid reset of the electromagnet 13.

[0027] In this embodiment, a second telescopic rod 11 is provided on the inner side of the spring 12. One end of the second telescopic rod 11 is fixed to the fixing plate 10, and the other end is fixed to the electromagnet 13. The second telescopic rod 11 guides the spring 12, preventing the spring 12 from bending and being damaged.

[0028] In this application, an annular groove is provided axially on the inner wall of the threaded hole, and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the threaded rod 17 at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0029] It should be noted that cylinders, servo motors, etc., are existing technologies, and those skilled in the art can configure them according to actual needs; therefore, they will not be elaborated upon here.

[0030] The use of this utility model involves the following steps:

[0031] S1: First, place the box on top of the bottom plate 6 and within the two second positioning brackets 7, then activate the electromagnet 13 to attract the door panel onto the electromagnet 13.

[0032] S2: Then start the servo motor. The output shaft of the servo motor drives the threaded rod 17 to rotate. The threaded rod 17 drives the two slides 18 to move inward towards each other. The two slides 18 respectively drive the two second positioning frames 7 to move inward, so that the inclined surface 21 on the inner side of the second positioning frame 7 contacts the box and pushes the box to the middle position. At the same time, the first telescopic rod 5 drives the first positioning frame 4 to move inward, so that the inclined surface 21 of the first positioning frame 4 contacts the door panel and pushes the door panel to the middle position, aligning the door panel with the box.

[0033] S3: Then start cylinder 2. Cylinder 2 drives the support frame 3 and the door panel to move downward, so that the door panel fits into the box. Then the workers assemble them together.

[0034] S4: After assembly, start the servo motor. The output shaft of the servo motor drives the threaded rod 17 to rotate. The threaded rod 17 drives the two slides 18 to move outwards in opposite directions. The first positioning frame 4 and the second positioning frame 7 are disengaged from the door panel and the box body respectively. Then, turn off the electromagnet 13 to disengage the electromagnet 13 from the door panel.

[0035] S5: The cylinder 2 moves the support frame 3 upward to reset it. At the same time, multiple springs 12 rebound and push the electromagnet 13 to the middle position, thus quickly resetting the electromagnet 13.

[0036] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
