Description

Technical Field

[0001] The present invention relates to the technical field of part assembly, and particularly to an automatic sleeve assembly device. Background Art

[0002] A metal sleeve, namely a metal bushing, is a common mechanical component used to connect or support other structures. When in use, a rubber sleeve is usually assembled on its outer surface. The rubber sleeve is made of a soft material and has many different characteristics compared with metal, and can play roles such as shock absorption and buffering, sealing and leakage prevention, increasing friction, protecting the metal surface, providing insulation, etc.

[0003] When the existing rubber sleeve is sleeved on the outer surface of the metal bushing, an expansion mechanism is usually required to assist in the installation of the rubber sleeve. Since the rubber sleeve has a certain elasticity, the expansion mechanism can traction the rubber sleeve to stretch and expand the size of the rubber sleeve. After the rubber sleeve can be sleeved on the outside of the bushing, the expansion mechanism is then withdrawn from the inside of the rubber sleeve. However, during the process of withdrawing the expansion mechanism from the inside of the rubber sleeve, it is easy to bring out the rubber sleeve, resulting in assembly failure. For this reason, an automatic sleeve assembly device is proposed. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-7, As shown in the figure, a sleeve automatic assembly device includes a workbench 1. The workbench 1 includes a bottom plate 11, an intermediate plate 12, and a top plate 13 arranged in sequence from bottom to top. The bottom plate 11, the intermediate plate 12, and the top plate 13 are all connected by connecting columns 14. The connecting columns 14 between the intermediate plate 12 and the top plate 13 are located at the center of the top plate 13. There are multiple groups of moving mechanisms 2 arranged between the intermediate plate 12 and the top plate 13. The upper surface of the moving end of the moving mechanism 2 is provided with a telescopic mechanism 3, and the upper surface of the fixed end of the moving mechanism 2 is provided with a fixing mechanism 4. A rotating mechanism 5 is arranged between the bottom plate 11 and the intermediate plate 12, and the rotating mechanism 5 can drive the moving mechanism 2 to rotate synchronously;

[0029] The middle parts around the outer surface of the top plate 13 all have inwardly concave grooves. When the moving directions of the moving mechanisms 2 are aligned, the telescopic mechanism 3 can move into or out of the grooves.

[0030] Furthermore, four groups of moving mechanisms 2 are provided, and the moving mechanisms 2 are arranged in a circular array with the center of the top plate 13 as the axis.

[0031] In this embodiment, when the telescopic mechanism 3 is located inside the groove, the telescopic mechanism 3 is in a retracted state. The rubber sleeve can be sleeved on the outer surface of the telescopic end of the telescopic mechanism 3, and then the moving mechanism 2 is used to drive the whole telescopic mechanism 3 to move out of the groove. At this time, the telescopic mechanism 3 is in an expanded state, and the telescopic mechanism 3 pulls the rubber sleeve to expand the rubber sleeve. Then, the bushing is placed at the center of the upper surface of the top plate 13, and the bushing is located inside the expanded rubber sleeve. Then, the rotating mechanism 5 is used to drive the moving mechanism 2 and the fixing mechanism 4 to rotate, and the fixing mechanism 4 thus moves towards the outer surface of the bushing. During this process, the fixing mechanism 4 drives the local movement of the rubber sleeve and presses the rubber sleeve on the outer surface of the bushing. Finally, the telescopic end of the telescopic mechanism 3 contracts, and the expanded rubber sleeve contracts and can be sleeved on the outer surface of the bushing.

[0032] In summary, by setting the moving mechanism 2 to cooperate with the telescopic mechanism 3, the rubber sleeve can be expanded so that the bushing can be placed on the upper surface of the top plate 13 and located inside the rubber sleeve. In addition, by setting the rotating mechanism 5 to cooperate with the fixing mechanism 4, the fixing mechanism 4 can press and install the local part of the rubber sleeve on the outer surface of the bushing, which can ensure that when the telescopic mechanism 3 is pulled out from inside the rubber sleeve, the rubber sleeve can be relatively stably sleeved on the surface of the bushing.

[0033] Furthermore, each moving mechanism 2 includes a sliding seat 21. A slider 23 is slidably installed inside the sliding seat 21. An electric push rod 22 is fixedly installed on one side of the sliding seat 21. The telescopic end of the electric push rod 22 is fixedly connected to the slider 23. The telescopic mechanism 3 is located on the upper surface of the slider 23, and the fixing mechanism 4 is located on the upper surface of the sliding seat 21.

[0034] In this embodiment, by driving the electric push rod 22 to expand and contract, the slider 23 can be driven to move inside the sliding seat 21, and then the telescopic mechanism 3 can be driven to move.

[0035] Furthermore, the telescopic mechanism 3 includes an outer cylinder body 31 fixedly installed on the upper surface of the slider 23. The upper end of the outer cylinder body 31 is slidably inserted with a telescopic rod 32. A magnetic block 33 is fixedly connected to the lower surface of the telescopic rod 32. An electromagnet 34 is fixedly connected to the inner bottom surface of the outer cylinder body 31. And a support spring 35 is fixedly connected between the inner bottom surface of the outer cylinder body 31 and the lower end of the telescopic rod 32. The electromagnet 34 is energized to attract the magnetic block 33.

[0036] In this embodiment, when the electromagnet 34 is not energized, the support spring 35 supports the telescopic rod 32, so that the upper end of the telescopic rod 32 is located outside the outer cylinder body 31. It should be noted that when the rubber sleeve is sleeved, the rubber sleeve should be located outside the telescopic rod 32; when it is necessary to withdraw the telescopic rod 32 from the inside of the rubber sleeve, only the electromagnet 34 needs to be energized. After the electromagnet 34 is energized, it can attract the magnetic block 33 and the telescopic rod 32, so that the telescopic rod 32 moves into the inner part of the outer cylinder body 31, and then the telescopic rod 32 can be withdrawn from the inside of the rubber sleeve.

[0037] Furthermore, the fixing mechanism 4 includes a column 41 fixedly installed on the upper surface of the sliding seat 21. Both sides of the upper surface of the column 41 are fixedly connected with arc-shaped plates 42. One end of the arc-shaped plate 42 far away from the column 41 is fixedly connected with a pressing block 43.

[0038] Furthermore, the height of the column 41 is equal to that of the top plate 13. The arc-shaped plate 42 and the pressing block 43 are located above the top plate 13.

[0039] Furthermore, the upper surface of the outer cylinder body 31 is flush with the upper surface of the top plate 13. When the electromagnet 34 is energized to attract the magnetic block 33 and the telescopic rod 32 to move downwards, the upper surface of the telescopic rod 32 is flush with the upper surface of the top plate 13.

[0040] In this embodiment, the pressing block 43 can actually be set as a flexible rubber block, which has a certain deformation ability. When the pressing block 43 presses on the outer surface of the bushing, the pressing block 43 can undergo corresponding deformation, so that the pressing block 43 can stably press the rubber sleeve and improve the stability.

[0041] Furthermore, the rotating mechanism 5 includes a rotating shaft 51 fixedly installed on the lower surface of the sliding seat 21. The rotating shaft 51 penetrates below the partition plate 12 and is fixedly connected with a driven gear 52. The middle part of the upper surface of the bottom plate 11 is fixedly connected with a motor 54. The output shaft of the motor 54 is fixedly connected with a driving gear 53. The driven gear 52 and the driving gear 53 are meshed.

[0042] In this embodiment, by driving the motor 54 to rotate, the driving gear 53 can be driven to rotate, and then the driven gear 52 and the rotating shaft 51 can be driven to rotate, so as to adjust the angle of the moving mechanism 2, so that the fixing mechanism 4 can press the rubber sleeve on the outer surface of the bushing.

[0043] It should be noted that when the moving mechanism 2 drives the telescopic mechanism 3 into the groove body, it is necessary to first use the rotating mechanism 5 to drive the moving mechanism 2 to rotate so that the sliding seat 21 is aligned with the groove body, and then use the moving mechanism 2 to drive the telescopic mechanism 3 into the groove body.

[0044] Furthermore, a bushing connector 6 is provided on the upper surface of the top plate 13, and the bushing connector 6 is detachably connected to the top plate 13.

[0045] Furthermore, the bushing connector 6 includes a cylinder body 61 and a connecting bolt 62. There are multiple groups of cylinder bodies 61, and the sizes of each group of cylinder bodies 61 are different. A connecting bolt 62 is fixedly connected to the center of the bottom of the cylinder body 61, and the cylinder body 61 is threadedly installed on the center of the upper surface of the top plate 13 through the connecting bolt 62.

[0046] In the existing bushing, there is a through hole in the middle. In this embodiment, by providing the cylinder body 61, the bushing can be sleeved on the outer surface of the cylinder body 61. In addition, since there are different sizes of bushings, the cylinder body 61 is detachable by providing the connecting bolt 62. When different sizes of bushings need to be assembled, the cylinder body 61 of the corresponding size can be installed on the upper surface of the top plate 13 by using the connecting bolt 62, that is, the bushing of this size can be sleeved on the outer surface of this cylinder body 61, improving the applicability of the device.

[0047] It should be noted that: in this application, the switch interfaces of the electric push rod 22, the electromagnet 34, and the motor 54 are all connected to an external power source through wires. Among them, the circuits and related operating principles involved are all existing conventional technologies, which will not be elaborated here. And in order to cooperate with the movement of the electromagnet 34 and the electric push rod 22, a section of wire can be reserved and a space can be provided to ensure that the electromagnet 34 and the electric push rod 22 can move.

[0048] In this embodiment, the models of the electric push rod 22, the electromagnet 34, and the motor 54 are not limited. At the same time, buttons can be provided on the outer surface of the workbench 1, and a battery assembly can be provided on the workbench 1 or any other part to provide corresponding power for the electric push rod 22, the electromagnet 34, and the motor 54. Pressing the button can control the switches of the electric push rod 22, the electromagnet 34, or the motor 54; if the electric push rod 22, the electromagnet 34, or the motor 54 is automatically switched, a control machine can also be added as a controller for cooperation. The control machine can be selected to cooperate with a PCB control board or a microcontroller, etc. Here, the model is not required.

[0049] Usage process: First, the user starts the rotation of the rotating mechanism 5 to drive the sliding seat 21 to rotate. When the sliding seat 21 is aligned with the groove body, the rotation of the rotating mechanism 5 is stopped. Then, the electric push rod 22 is driven to extend, driving the slider 23 and the telescopic mechanism 3 to move towards one side of the groove body until the telescopic mechanism 3 reaches the retracted state. Next, the rubber sleeve is sleeved outside the telescopic rod 32. Then, the electric push rod 22 is driven to contract, driving the telescopic mechanism 3 to move towards the outside of the groove body, making the rubber sleeve expand. Then, the bushing is sleeved on the outer surface of the cylinder 61, and the rotating mechanism 5 is used to drive the sliding seat 21 and the fixing mechanism 4 to rotate until the pressing block 43 presses a part of the rubber sleeve on the outer surface of the bushing. Finally, the power supply of the electromagnet 34 is turned on, and the electromagnet 34 attracts the magnetic block 33 to move, so that the telescopic rod 32 is withdrawn from the inside of the rubber sleeve, and the expanded rubber sleeve can thus contract and be sleeved on the outer surface of the bushing. During this process, a part of the rubber sleeve is fixed by the pressing block 43, so that the rubber sleeve can be stably sleeved on the outer surface of the bushing.
