It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0029] Because the existing technology has the technical problem of time-consuming and laborious manual measurement or high cost of using laser equipment to measure the length of the guide rail.

[0030] Please refer to Figures 1-5 In order to solve the above technical problems, the utility model provides a bearing dismounting device for dismounting the bearing 6 on the shaft 5, comprising: a dismounting body 1, one end of the dismounting body 1 is provided with a fixed part 11, and the other end is provided with a compression part 12; a fixed part 2, the fixed part 2 is detachably connected to the fixed part 11, and the fixed part 2 is used for fixing the bearing 6; a compression part 3, the compression part 3 is rotatably connected to the compression part 12, and the compression part 3 is used for abutting the end face of the shaft 5 where the bearing 6 is located.

[0031] In the embodiment of the utility model, the bearing 6 is fixed by the fixed part 2, the compression part 3 abuts the end face of the shaft 5 where the bearing 6 is located, the compression part 3 is relatively displaced with the dismounting body 1 by rotating the compression part 3, the bearing 6 is relatively displaced with the shaft 5 where it is located along with the dismounting body 1, thereby completing the dismounting of the bearing 6, compared with the traditional dismounting method using wrenches and other tools, the operation is simple and fast, and the working efficiency of bearing dismounting is improved. Specifically, one end of the compression part 3 away from the shaft 5 is provided with a rotating rod (not shown), the rotating rod is perpendicular to the compression part 3, and is used for rotating the compression part 3. According to the lever principle, the longer the length of the rotating rod is, the less the force required for rotating the compression part 3 to lift the bearing 6 is. The setting of the rotating rod enables the worker to rotate the compression part 3 more simply, so that the dismounting of the bearing 6 is more labor-saving and time-saving.

[0032] In some embodiments, the dismounting body 1 is internally provided with a containing cavity 13. In this embodiment, the containing cavity 13 provides a dismounting space for the bearing 6 and the shaft 5. Compared with the traditional dismounting tool, the dismounting space of the bearing 6 is controlled in the containing cavity 13, effectively preventing the bearing 6 from flying out and causing damage to the workers and the bearing itself in the moment of dismounting away from the shaft 5.

[0033] In some embodiments, the fixed part 11 is provided with a first communication hole 111 for passing through the bearing 6, and the fixing member 2 is used to abut against one end of the bearing 6 close to the first communication hole 111. In this embodiment, the bearing 6 extends into the containing cavity 13 through the first communication hole 111, and the fixing member 2 abuts against one end of the bearing 6 close to the first communication hole 111, i.e. the fixing member 2 fixes the bearing 6 in the containing cavity 13, thereby ensuring that when the pressing member 3 rotates, the pressing member 3 abuts against the end face of the shaft 5, the bearing 6 moves relative to the pressing member 3 along with the dismounting body 1, i.e. the bearing 6 moves relative to the shaft 5, thereby completing the dismounting of the bearing 6.

[0034] In some embodiments, the fixed part 11 is provided with at least one pair of second communication holes 112, the fixing member 2 is provided with a third communication hole 21 corresponding to each of the second communication holes 112, and the bearing dismounting device further comprises a connecting member 4 which is detachably connected to the second communication holes 112 and the third communication holes 21. In this embodiment, the connecting member 4 passes through the second communication holes 112 and the third communication holes 21, i.e. connects the fixing member 2 and the fixed part 11 together, and the fixing member 2 abuts against the bearing 6, thereby ensuring that the bearing 6 moves along with the dismounting body 1. Specifically, the fixing member 2 is in the shape of a long plate, and at least one pair of third communication holes 21 are respectively arranged at both ends of the fixing member 2. In this embodiment, the length of the fixing member 2 is longer than the diameter of the first communication hole 111, and the diameter of the first communication hole 111 is longer than the diameter of the bearing 6. The long plate-shaped fixing member 2 can be fixed to the end face of the fixed part 11 around the first communication hole 111, the middle part of the long plate-shaped fixing member 2 can abut against the bearing 6, and the long plate-shaped fixing member 2 is suitable for bearings of various sizes and types, has strong versatility, and can meet the dismounting needs of bearings of different specifications.

[0035] More specifically, the connecting member 4 comprises a bolt 41 and a nut 42, the bolt 41 passes through the second communication holes 112 and the third communication holes 21 in sequence and is connected with the nut 42, or the bolt 41 passes through the third communication holes 21 and the second communication holes 112 in sequence and is connected with the nut 42. In this embodiment, the fixing member 2 and the fixed part 11 are detachably connected through the bolt 41 and the nut 42. The connecting structure of the bolt 41 and the nut 42 is simple and has low cost. Among the two connection directions of the bolt 41, the connection in the direction of Figure 2 is more convenient. The bolt 41 is pre-set on the second communication hole 112, and only the second communication hole 112 and the third communication hole 21 need to be aligned, and then the fixing member 2 and the fixed part 11 are connected together through the nut 42.

[0036] In some embodiments, the pressing part 12 is provided with a fourth connecting hole 121 for connecting the pressing member 3. In this embodiment, the fourth connecting hole 121 is passed through by the pressing part 12, so that one end of the pressing member 3 abuts against the end of the shaft 5 where the bearing 6 is located.

[0037] Specifically, the pressing member 3 is a screw rod, and the screw rod is connected with the fourth connecting hole 121 through threads. In this embodiment, rotating the screw rod connected with the fourth connecting hole 121 through threads can move the bearing 6 relative to the shaft 5. The rotating operation of the screw rod is simple, and the disassembly of the bearing 6 is convenient and fast.

[0038] In some embodiments, one end of the pressing member 3 abutting against the end face of the shaft 5 is conical. In this embodiment, the conical end of the pressing member 3 helps to reduce the force used for rotating the pressing member 3, facilitates the disassembly of the staff, reduces the working intensity, and saves time and effort.

[0039] In some embodiments, the disassembly body 1 is cylindrical, and the fixing part 11 is annular. In this embodiment, the existing bearing disassembly often uses a bearing puller or a bearing disassembly hook, both of which use a hook claw to fix the bearing. In actual operation, the bearing itself is easily damaged, and the bearing is not convenient to recycle. The use of the cylindrical disassembly body 1 and the annular fixing part 11 can effectively prevent damage to the bearing 6 during disassembly and facilitate the reuse of the bearing 6. Specifically, the disassembly body 1 can be designed into a square or other irregular shell, and only the fourth connecting hole 121 for the pressing member 3 to pass through and be rotatably connected is arranged at the top of the disassembly body 1, and the first communicating hole 111 for the bearing 6 to pass through is arranged at the bottom of the disassembly body 1, and the bearing 6 is completed by the fixing member 2.
