[0024] The utility model will be further described below in conjunction with the accompanying drawings.

[0025] like Figure 1 and Figure 2 As shown, the wear sleeve disassembly and assembly device of one embodiment of the utility model comprises a base 1, on which a first mechanical arm 2 and a second mechanical arm 3 are provided, the first mechanical arm 2 is provided with a first hydraulic clamp 4 for disassembling the wear sleeve 100, and the second mechanical arm 3 is provided with a second hydraulic clamp 5 for installing the wear sleeve 100. Figure 3 and Figure 4 As shown, the first hydraulic pliers 4 include a first bending arm 41, a first hydraulic cylinder 42 and a first push rod 43. The first hydraulic cylinder 42 is arranged at one end of the first bending arm 41, and the first push rod 43 is arranged on the first hydraulic cylinder 42. A U-shaped bracket 44 is arranged at one end of the first bending arm 41 away from the first hydraulic cylinder 42. The U-shaped bracket 44 is arranged opposite to the first hydraulic cylinder 42. Figure 5 and Figure 6 As shown, the second hydraulic pliers 5 include a second bending arm 51, a second hydraulic cylinder 52 and a second push rod 53. The second hydraulic cylinder 52 is arranged at one end of the second bending arm 51, and the second push rod 53 is arranged on the second hydraulic cylinder 52. A positioning block 54 is provided at one end of the second bending arm 51 away from the second hydraulic cylinder 52, and the positioning block 54 is arranged opposite to the second hydraulic cylinder 52.

[0026] The first hydraulic clamp 4 on the first mechanical arm 2 is provided with a U-shaped bracket 44, which can not only support the wear sleeve 100, but also allow the rivet 200 to pass through. The first hydraulic cylinder 42 can push out the rivet 200 on the wear sleeve 100 by driving the first push rod 43, so that the wear sleeve 100 can be removed from the brake beam 300, and the wear sleeve 100 is disassembled. The second hydraulic clamp 5 on the second mechanical arm 3 is provided with a positioning block 54, which can not only support the wear sleeve 100, but also provide a limit for the rivet 200 to prevent the rivet 200 from jumping out during the installation process. The second hydraulic cylinder 52 can push the rivet 200 into place by driving the second push rod 53, and the installation of the wear sleeve 100 is completed. The wear sleeve disassembly and assembly device of the present embodiment can realize both the installation and disassembly of the wear sleeve 100. The first hydraulic clamp 4 adjusts the position through the first mechanical arm 2, and the second hydraulic clamp 5 adjusts the position through the second mechanical arm 3. No manual operation is required, and it has a high degree of automation, which can improve the disassembly and assembly efficiency of the wear sleeve 100.

[0027] like Figure 3 and Figure 4 As shown, the U-shaped bracket 44 includes two support plates 441 arranged opposite to each other, and the side of the U-shaped bracket 44 facing the first hydraulic cylinder 42 is perpendicular to the moving direction of the first push rod 43. During the disassembly process of the wear sleeve 100, when the first push rod 43 pushes out the rivet 200, the U-shaped bracket 44 provides a certain support for the wear sleeve 100, which helps the wear sleeve 100 to remain stable. The side of the U-shaped bracket 44 facing the first hydraulic cylinder 42 is perpendicular to the moving direction of the first push rod 43, so that the support force provided by the U-shaped bracket 44 is opposite to the direction of the force applied by the first push rod 43, so that the wear sleeve 100 remains in a stable state.

[0028] like Figure 4 As shown, the distance between the two support plates 441 is greater than the diameter of the first push rod 43, and the first push rod 43 faces the gap between the two support plates 441. The rivet 200 will pass through the gap between the two support plates 441, and the gap between the two support plates 441 needs to be greater than the diameter of the rivet 200. In order to push the rivet 200 out, the diameter of the first push rod 43 needs to be smaller than the diameter of the rivet 200. Therefore, the distance between the two support plates 441 needs to be greater than the diameter of the first push rod 43.

[0029] The first curved arm 41 is C-shaped, and the first hydraulic cylinder 42 and the U-shaped bracket 44 are respectively welded and fixed at both ends of the first curved arm 41. The C-shaped first curved arm 41 has a simple structure, so that the first hydraulic cylinder 42 and the U-shaped bracket 44 can be arranged relatively, and the welding fixation method ensures the reliability of the connection.

[0030] Furthermore, the first hydraulic pliers 4 further includes a first connection plate 45, which is disposed on the first curved arm 41, and the first hydraulic pliers 4 is connected to the first mechanical arm 2 via the first connection plate 45. The first curved arm 41 is a relatively slender component, and its thickness is also small, and it is not convenient to directly connect with the first mechanical arm 2, so the first connection plate 45 is disposed on the first curved arm 41, so that the first hydraulic pliers 4 can be easily installed and fixed.

[0031] Specifically, the first connection plate 45 is in a round shape with a relatively large area, and a plurality of fixing holes 451 are provided on the first connection plate 45 , so that the first connection plate 45 can be stably connected to the first robot arm 2 .

[0032] like Figure 4 As shown, further, a plurality of fixing holes 451 are evenly spaced and distributed on the same circumference. Not only is the number of the fixing holes 451 large, but also the first connecting plate 45 is connected to the first robotic arm 2 at all circumferential locations, thereby achieving a better fixing effect.

[0033] like Figure 5 and Figure 6 As shown, the structure of the second hydraulic clamp 5 is basically the same as that of the first hydraulic clamp 4, except that the positioning block 54 and the U-shaped bracket 44 are different. The second hydraulic clamp 5 is also fixed to the second mechanical arm 3 through the second connecting plate 55 provided on the second curved arm 51. The side of the positioning block 54 facing the second hydraulic cylinder 52 is perpendicular to the moving direction of the second push rod 53. When the wear sleeve 100 is installed, the surface of the positioning block 54 can provide stable and reliable support for the wear sleeve 100, so as to prevent the wear sleeve 100 from moving and causing the rivet 200 to fail to be installed properly.

[0034] In this embodiment, the first robotic arm 2 and the second robotic arm 3 are both six-axis robotic arms with high flexibility, and can accurately adjust the position and placement angle of the first hydraulic clamp 4 and the second hydraulic clamp 5 to meet the disassembly and installation requirements of the wear sleeve 100.

[0035] like Figure 1 As shown, the first robotic arm 2 is fixed to the top surface of the base 1, and the second robotic arm 3 is fixed to the side surface of the base 1, so that one base 1 can meet the installation requirements of the first robotic arm 2 and the second robotic arm 3, with low cost. Moreover, since the first robotic arm 2 and the second robotic arm 3 are respectively arranged on different surfaces, interference between the two is not likely to occur, and there is sufficient space for the first robotic arm 2 and the second robotic arm 3 to operate.

[0036] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
