Description

[0002] A metal sleeve, also known as a metal shaft sleeve, is a common mechanical component used to connect or support other structures. When in use, a metal sleeve is typically fitted with a rubber sleeve. Rubber sleeves are a soft material that offers many different properties than metal, including shock absorption, leak-proof sealing, friction enhancement, surface protection, and insulation.

[0003] When an existing rubber sleeve is installed on the outer surface of a metal sleeve, 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 pull the rubber sleeve to stretch and expand the size of the rubber sleeve. After the rubber sleeve is installed on the outside of the sleeve, the expansion mechanism is then removed from the rubber sleeve. However, during the process of removing the expansion mechanism from the rubber sleeve, the rubber sleeve is easily pulled out, resulting in assembly failure. To address this issue, an automatic sleeve assembly device is proposed. Summary of the Invention

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 7, the figure shows an automatic sleeve assembly device, including a workbench 1, which 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 connected by a connecting column 14, the connecting column 14 between the intermediate plate 12 and the top plate 13 is located at the center of the top plate 13, multiple groups of moving mechanisms 2 are 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, the upper surface of the fixed end of the moving mechanism 2 is provided with a fixing mechanism 4, a rotating mechanism 5 is provided 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 top plate 13 has an inwardly concave groove in the middle of the four sides of the outer surface. When the moving direction of the moving mechanism 2 is aligned, the telescopic mechanism 3 can move into or out of the groove.

[0030] Furthermore, four groups of moving mechanisms 2 are provided, and the moving mechanisms 2 are distributed in a ring 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 body, the telescopic mechanism 3 is in a retracted state, and the rubber sleeve can be placed on the outer surface of the telescopic end of the telescopic mechanism 3. Then, the moving mechanism 2 is used to drive the telescopic mechanism 3 to move out of the groove body as a whole. At this time, the telescopic mechanism 3 is in an open state, and the telescopic mechanism 3 pulls the rubber sleeve to expand the rubber sleeve. Then, the shaft sleeve is placed at the center of the upper surface of the top plate 13, and the shaft sleeve is located inside the expanded rubber sleeve. The rotating mechanism 5 is then used to drive the moving mechanism 2 and the fixing mechanism 4 to rotate, and the fixing mechanism 4 moves toward the outer surface of the shaft sleeve. During this process, the fixing mechanism 4 drives the rubber sleeve to move locally and presses the rubber sleeve on the outer surface of the shaft sleeve. Finally, the telescopic end of the telescopic mechanism 3 is contracted, and the expanded rubber sleeve is contracted and can be sleeved on the outer surface of the shaft sleeve.

[0032] In summary, by setting up the moving mechanism 2 in conjunction with the telescopic mechanism 3, the rubber sleeve can be expanded so that the shaft sleeve can be placed on the upper surface of the top plate 13 and located inside the rubber sleeve. In addition, by setting up the rotating mechanism 5 in conjunction with the fixing mechanism 4, the fixing mechanism 4 can locally press the rubber sleeve onto the outer surface of the shaft sleeve, which can ensure that when the telescopic mechanism 3 is pulled out from the inside of the rubber sleeve, the rubber sleeve can be relatively stably mounted on the surface of the shaft sleeve.

[0033] Furthermore, the moving mechanism 2 includes a slide 21, a slider 23 is slidably installed inside the slide 21, an electric push rod 22 is fixedly installed on one side of the slide 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 slide 21.

[0034] In this embodiment, by driving the electric push rod 22 to extend and retract, the slider 23 can be driven to move inside the slide seat 21, and further the retractable mechanism 3 can be driven to move.

[0035] Furthermore, the telescopic mechanism 3 includes an outer cylinder 31 fixedly mounted on the upper surface of the slider 23, a telescopic rod 32 is slidably inserted into the upper end of the outer cylinder 31, a magnet 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 31, and a support spring 35 is fixedly connected between the inner bottom surface of the outer cylinder 31 and the lower end of the telescopic rod 32, and the electromagnet 34 is energized to attract the magnet 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 31. It should be noted that when the rubber sleeve is installed, the rubber sleeve should be located outside the telescopic rod 32; when the telescopic rod 32 needs to be removed from the rubber sleeve, it is only necessary to energize the electromagnet 34. The electromagnet 34 can attract the magnetic block 33 and the telescopic rod 32, so that the telescopic rod 32 moves into the outer cylinder 31, and the telescopic rod 32 can be removed from the rubber sleeve.

[0037] Furthermore, the fixing mechanism 4 includes a column 41 fixedly mounted on the upper surface of the slide 21 , arc-shaped plates 42 are fixedly connected to both sides of the upper surface of the column 41 , and a pressure block 43 is fixedly connected to one end of the arc-shaped plate 42 away from the column 41 .

[0038] Furthermore, the upright column 41 is at the same height as the top plate 13 , and 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 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 downward, 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 is pressed on the outer surface of the sleeve, the pressing block 43 can undergo corresponding deformation, so that the pressing block 43 can stably press the rubber sleeve and improve stability.

[0041] Furthermore, the rotating mechanism 5 includes a rotating shaft 51 fixedly mounted on the lower surface of the slide 21, the rotating shaft 51 passes through the bottom of the intermediate plate 12 and is fixedly connected to a driven gear 52, a motor 54 is fixedly connected to the middle of the upper surface of the base plate 11, and the output shaft of the motor 54 is fixedly connected to the driving gear 53, and the driven gear 52 is meshed with the driving gear 53.

[0042] In this embodiment, by driving the motor 54 to rotate, the driving gear 53 can be driven to rotate, which can drive the driven gear 52 and the rotating shaft 51 to rotate, thereby adjusting the angle of the moving mechanism 2 so that the fixing mechanism 4 can press the rubber sleeve onto the outer surface of the sleeve.

[0043] It should be noted that when the moving mechanism 2 drives the telescopic mechanism 3 to move into the slot, the rotating mechanism 5 needs to be used to drive the moving mechanism 2 to rotate so that the slide 21 is aligned with the slot, and then the moving mechanism 2 is used to drive the telescopic mechanism 3 to move into the slot.

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

[0045] Furthermore, the shaft sleeve connector 6 includes a column 61 and a connecting bolt 62. There are multiple groups of columns 61, and the size of each group of columns 61 is different. The connecting bolt 62 is fixedly connected to the center of the bottom of the column 61, and the column 61 is threadedly installed at the center of the upper surface of the top plate 13 through the connecting bolt 62.

[0046] The existing sleeve has a through hole in the middle. In this embodiment, the sleeve can be mounted on the outer surface of the sleeve 61 by setting a column 61. In addition, since the sleeves come in different sizes, the column 61 is made detachable by setting a connecting bolt 62. When sleeves of different sizes need to be assembled, the connecting bolt 62 can be used to install the column 61 of the corresponding size on the upper surface of the top plate 13, that is, the sleeve of this size can be mounted on the outer surface of the column 61, thereby 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 the external power supply through wires. The circuits involved and the related operating principles are all existing conventional technologies and will not be repeated here. In order to cooperate with the movement of the electromagnet 34 and the electric push rod 22, a length of wire can be reserved to provide a space to ensure that the electromagnet 34 and the electric push rod 22 can move.

[0048] In this embodiment, there is no restriction on the models of the electric push rod 22, the electromagnet 34 and the motor 54. At the same time, a button 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 switch of the electric push rod 22, the electromagnet 34 or the motor 54. If an automatic switch electric push rod 22, the electromagnet 34 or the motor 54 is used, a control machine can also be added as a controller for use in conjunction. The control machine can be a PCB control board or a micro single-chip microcomputer, etc., and the model is not required here.

[0049] When the lever 21 is in the closed position, the push rod 22 is pulled out of the engagement ring 23 and the locking mechanism 3 is engaged, and the locking mechanism 3 is engaged with the locking mechanism 32.
