DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0028] The present application embodiment provides a rail buckle nut installation device, such as Figure 1-Figure 7 As shown, it includes a support plate 1, an adsorption cylinder 3, a rotating mechanism, a track wheel 6, etc.

[0029] Specifically, baffles 101 are provided on both sides of the support plate 1, and the distance between the baffles 101 matches the distance between the two side surfaces on the opposite sides of the nut 2 to be installed (the nut to be installed is usually an external hexagonal nut, and the two surfaces of the circumference that are parallel to each other are the two side surfaces on the opposite sides), and the distance between the top of the baffle 101 and the top of the support plate 1 is smaller than the height of the nut 2; the adsorption cylinder 3 is a pair, and its internal cross-section matches the shape of the nut 2, and its bottom is magnetic and is used to adsorb the nut 2, which is connected to the lifting end of a pair of lifting mechanisms 4, and the lifting mechanisms 4 are connected to the telescopic end of a telescopic mechanism 5, and the telescopic end of the telescopic mechanism 5 is connected to the telescopic end of the telescopic mechanism 5. The retracting mechanism 5 is fixed to the support plate 1, and its retracting direction is parallel to the length direction of the support plate 1. When the lifting mechanism 4 drives the adsorption cylinder 3 to move upward to the maximum limit, and the retracting mechanism 5 drives the retracting mechanism 5 to move toward the middle of the support plate 1 to the maximum limit, a pair of adsorption cylinders 3 are respectively located at the two ends of the top surface of the support plate 1, and the distance between the bottom surface of the adsorption cylinder 3 and the support plate 1 is greater than the height of the nut 2; the rotating mechanism is connected to the adsorption cylinder 3, and is used to drive the adsorption cylinder 3 to rotate; the track wheels 6 are a pair, which are arranged under the support plate 1, and their axial directions are parallel to the length direction of the support plate 1, and are used to drive the device to move along the track.

[0030] In actual use, the track wheel 6 is placed on the track to be fixed, and the device is pushed to between a pair of studs on both sides of the track. Then, the adsorption cylinder 3 is controlled to rotate so that the two symmetrical sides inside it are parallel to the baffle 101. Then, the two nuts 2 are placed at both ends of the top surface of the support plate 1 so that the two opposite sides of the nut 2 are parallel to the baffle 101. Because the distance between the top of the baffle 101 and the top of the support plate 1 is less than the height of the nut 2, the top of the nut 2 will protrude from the top of the support plate 1. At this time, the lifting mechanism 4 is controlled to drive the adsorption cylinder 3 to move upward to the maximum limit, and the telescopic mechanism 5 is controlled. Drive the lifting mechanism 4 to move toward the middle of the support plate 1 to its maximum limit, and then control the lifting mechanism 4 to drive the adsorption tube 3 to move downward, so that the nut 2 enters the adsorption tube 3 and is adsorbed by the bottom of the adsorption tube 3 with magnetism, and then control the telescopic mechanism 5 to drive the lifting mechanism 4 to move a preset distance toward the outside of the support plate 1, and align the nut 2 with the stud on the side of the track, and then control the lifting mechanism 4 to drive the adsorption tube 3 to move downward to its maximum limit, so that the nut 2 is pushed into the adsorption tube 3 for a certain distance, and finally control the rotating mechanism to drive the adsorption tube 3 to rotate, so that the nut 2 can be screwed into the screw 701, and the installation of the nut 2 is completed.

[0031] For details, see Figure 3 , Figure 6 , Figure 7The lifting mechanism 4 includes a sleeve 401 and a first cylinder 402. The sleeve 401 is connected to the telescopic end of the telescopic mechanism 5. A pair of slide grooves 4011 are provided on the sleeve 401 parallel to the axial direction. A pair of first cylinders 402 are respectively arranged outside the pair of slide grooves 4011, and their telescopic ends are arranged upward. Two sliders 4012 are slidably connected in the pair of slide grooves 4011. The sliders 4012 are all passed through the slide grooves 4011 and connected to the telescopic ends of the first cylinders 402. The adsorption cylinder 3 is passed through the sleeve 401, and an annular groove 301 is provided on the circumference of the upper end thereof. The inner end of the slider 4012 is slidably connected in the annular groove 301. The first cylinder 402 can be pushed out or retracted to drive the adsorption cylinder 3 to rise or fall through the slider 4012.

[0032] For details, see Figure 3 , Figure 6 , Figure 7 The rotating mechanism includes a second motor 9 and a spline shaft 901. A connecting hole matching the spline shaft 901 is provided on the top of the adsorption cylinder 3. The spline shaft 901 is inserted into the connecting hole and its upper end is connected to the output shaft of the second motor 9. The second motor 9 is fixed to the sleeve 401. When the lifting mechanism 4 drives the adsorption cylinder 3 to descend, because the spline shaft 901 is inserted into the adsorption cylinder 3, the second motor 9 rotates and can still drive the adsorption cylinder 3 to rotate through the spline shaft 901, and screw the nut 2 into the stud.

[0033] Preferably, see Figure 3 , Figure 4 A two-way pushing mechanism 7 is provided on the support plate 1, and the two pushing directions of the two-way pushing mechanism 7 are respectively toward the two ends of the support plate 1. After the nut 2 is placed on the support plate 1, the two-way pushing mechanism 7 can automatically push the nut 2 to the preset positions at the two ends of the support plate 1, and no manual alignment is required.

[0034] For details, see Figure 2-Figure 4 The bidirectional ejection mechanism 7 includes a screw 701, a first motor 702, and a pair of push plates 703. The screw 701 has two sections of external threads with opposite rotation directions. A pair of strip-shaped through grooves 102 are provided on the support plate 1 along the length direction. The pair of push plates 703 are respectively slidably connected in the pair of strip-shaped through grooves 102. The top of the push plates 703 passes through the strip-shaped through grooves 102 to push the nuts 2 placed on the support plate 1. The bottom of the pair of push plates 703 passes through the strip-shaped through grooves 102 and is respectively threadedly connected with the two sections of external threads with opposite rotation directions of the screw 701. The axial direction of the screw 701 is parallel to the length direction of the support plate 1. One end of the screw 701 is connected to the output shaft of the first motor 702. When the nut 2 needs to be pushed, the first motor 702 is started to drive the screw 701 to rotate, which can drive the pair of push plates 703 to move in the opposite direction, and at the same time push the two nuts 2 to the preset positions at both ends of the support plate 1.

[0035] Preferably, see Figure 1A pair of accommodating tubes 8 are vertically spaced apart in the middle of the support plate 1. The internal cross section of the accommodating tube 8 matches the shape of the nut 2 and is used to place the nut 2. The distance between the bottom of the accommodating tube 8 and the support plate 1 matches the height of the nut 2. In actual use, multiple nuts 2 can be placed in the accommodating tube 8. Specifically, the two opposite side surfaces inside the accommodating tube 8 can be set to be parallel to the baffle 101. After the nut 2 is placed in the accommodating tube 8, the nut 2 at the bottom can directly fall onto the support plate 1. The push plate 703 of the pushing mechanism pushes the nut 2 to both ends of the support plate 1. After the push plate 703 is retracted, the nut 2 in the accommodating tube 8 can continue to fall onto the support plate 1. Repeating the above steps can push the nut 2 to the preset positions at both ends of the support plate 1 in sequence.

[0036] For details, see Figure 2 , Figure 4 , both sides of the push plate 703 are provided with protrusions 7031, and the height of the top surface of the protrusions 7031 matches the height of the top surface of the push plate 703. By providing the protrusions 7031, when the top of the push plate 703 is out of the range of the inner wall of the accommodating tube 8, the nut 2 above can be supported by the protrusions 7031, so that after the push plate 703 is retracted, the nut 2 at the upper end falls from the accommodating tube 8 onto the support plate 1.

[0037] The above are only some of the embodiments listed in this application and are not intended to limit this application.
