[0031] In order to solve the problem in the related art that the gap between the lower surface of some outer bearings and the contact surface of the sample after installation is very small or even no gap, and the traditional pulling tools cannot meet the space requirements, firstly, refer to Figure 1 An embodiment of the present application provides a special position external bearing disassembly device, including a threaded rod 1, a clamping arm 3 is rotatably connected to the threaded rod 1 through a first connecting member 2, the first connecting member 2 is used to rotatably connect the threaded rod 1 and the clamping arm 3, the threaded rod 1 is also provided with a first driving member 4 for driving the clamping arm 3 to move, and a clamping member 5 is provided at one end of the clamping arm 3 away from the first connecting member 2, and the clamping member 5 is used to clamp the external bearing.

[0032] In this embodiment, the clamping arm 3 is driven to rotate by the first driving member 4 until the clamping member 5 clamps the outer bearing, and the outer bearing is removed by pulling out the threaded rod 1 .

[0033] Reference Figure 1In some embodiments, the first connecting member 2 includes a clamp arm connecting frame 21, and the clamp arm 3 is rotatably connected to the clamp arm connecting frame 21. The threaded rod 1 is passed through and threadedly connected to the clamp arm connecting frame 21. The clamp arm connecting frame 21 is provided with a threaded hole matching the size of the threaded rod 1, and the threaded rod 1 is threadedly connected to the clamp arm connecting frame 21.

[0034] In this embodiment, the threaded rod 1 is threadedly connected to the clamp arm connecting frame 21, so that the clamp arm connecting frame 21 is not easily moved in the axial direction relative to the threaded rod 1 under the action of external force, thereby improving the stability between the threaded rod 1 and the clamp arm 3 and the clamp arm connecting frame 21 during the disassembly process.

[0035] The sliding rod 81 in the present application is threadedly connected to the threaded rod 1, the sliding hammer 83 can move freely on the sliding rod 81, the threaded rod 1 is threadedly matched with the clamp arm connecting frame 21, the threaded rod 1 and the transverse constraint frame 41 are inserted and locked with a nut 61, the clamp arm 3 and the clamp arm connecting frame 21 are pin-connected, the clamp arm 3 can freely pass through the transverse constraint frame 41 and be constrained by it, and the clamp block and the clamp arm 3 are pin-connected.

[0036] By rotating the threaded rod 1, the constraint frame is pushed downward, and the constraint frame constrains the clamp arm 3 to clamp inward, so that the clamp block clamps the sample, and the sliding hammer 83 moves upward to hit the upper end of the sliding rod 81, and continuously performs the knocking action, thereby realizing the removal of the outer bearing.

[0037] A special device is provided for converting the downward force of the thread rotation into an inward binding force and clamping the sample, and for disassembling the outer bearing using a slide hammer 83. The device has strong versatility and a wide range of applications, realizes the operability of disassembling the outer bearing at a special position, and improves the quality of sample disassembly.

[0038] Reference Figure 1 In some embodiments, the second connecting member 6 includes a nut 61 , and a connecting hole matching the size of the threaded rod 1 is opened on the lateral restraining frame 41 , and the nut 61 is threadedly connected to the threaded rod 1 .

[0039] In the process of restricting the transverse restraint frame 41, a force relative to the axis of the threaded rod 1 toward the clamping member 5 is applied to the transverse restraint frame 41 through the nut 61, and the inclined clamping arm 3 is pressed against the inner wall of the restraint hole of the transverse restraint frame 41, and a force resisting the force relative to the axis of the threaded rod 1 toward the clamping member 5 is generated, so that the clamping force of the clamping arm 3 generated by the transverse restraint frame 41 is finally applied entirely to the outer edge of the outer bearing. The setting of the transverse restraint frame 41 enables the clamping arm 3 to perform a stable clamping operation.

[0040] In this embodiment, the nut 61 is arranged to keep the transverse restraint frame 41 and the clamp arm 3 in a stable state. While the transverse restraint frame 41 generates a clamping force on the clamp arm 3, the reverse force of the nut 61 and the clamp arm 3 is kept stable, thereby improving the stability of the clamping member 5 during the clamping process.

A rotation pin 7 is passed through the clamp arm 3 and a corresponding rotation groove is opened on the clamp arm connecting frame 21, so that the rotation pin 7 can rotate in the rotation groove. At the same time, the rotation pin 7 makes it difficult for the clamp arm 3 to detach from the clamp arm connecting frame 21, thereby improving the stability of the clamp arm 3 during the clamping process.

[0043] In this embodiment, the transmission pin is used to ensure that the clamp arm 3 can rotate according to the rotating pin 7 and the clamp arm connecting frame 21. At the same time, during the rotation process, the clamp arm 3 and the clamp arm connecting frame 21 are not easily separated, so that the clamp arm 3 can stably perform the clamping operation. The special device that converts the downward force of the thread rotation into an inward binding force and clamps the sample and uses the slide hammer 83 to remove the outer bearing has strong versatility and a wide range of applications, realizes the operability of removing the outer bearing at a special position, and improves the sample removal quality.

[0044] Specifically, the clamp arm 3 and the clamp arm connecting frame 21 can also be connected by other rotatable structures. In this embodiment, a rotating hole is opened on the clamp arm connecting frame 21, and a rotating shaft is passed through and rotatably connected on the inner hole wall of the rotating hole. The rotating shaft is passed through and fixedly connected to the clamp arm 3, and the two end parts of the rotating shaft protrude from the clamp arm 3 and are rotatably connected to the inner hole wall of the rotating hole.

[0045] In this embodiment, the rotating shaft can be fixedly connected to the clamp arm 3, and a rotating hole is opened on the clamp arm connecting frame 21, and the two end parts of the rotating shaft extend out of the clamp arm 3 and are rotatably connected to the inner hole wall of the rotating hole.
