As shown in fig. 1, an embodiment of the present invention provides a bushing removing device, which includes a sliding rod 10, a sliding block 20, a connecting member 30, and a first limiting member 40. The sliding rod 10 has a first end and a second end which are opposite to each other, the sliding block 20 is disposed on the sliding rod 10 in a penetrating manner, and the sliding block 20 can slide between the first end and the second end of the sliding rod 10. Specifically, one end of the connecting member 30 is threadedly coupled to the first end of the slide bar 10, and the other end of the connecting member 30 is threadedly coupled to the bushing 50. Wherein, an internal thread may be provided on the bushing 50, and one end of the connecting member 30 is inserted into the bushing 50, so that the connecting member 30 is connected with the internal thread of the bushing 50; it is also possible to provide external threads on the bushing 50, and to connect the connecting member 30 to the external threads of the bushing 50 by fitting the connecting member 30 over the bushing 50. Specifically, the first limiting member 40 is disposed at the second end of the slide bar 10, and when the sliding block 20 slides on the slide bar 10, the first limiting member 40 can limit the sliding block 20 from disengaging from the slide bar 10.

With the bushing removing device provided in this embodiment, since the first end of the sliding rod 10 is connected to the bushing through the connecting member 30, and the second end of the sliding rod 10 is provided with the first limiting member 40, when the bushing 50 needs to be removed from the swing arm, an acting force is applied to the sliding block 20 by hand, so that the sliding block 20 slides from the first end to the second end of the sliding rod 10, and the sliding block 20 impacts the first limiting member 40, and under the impact force of the sliding block 20, the bushing 50 can be removed from the swing arm.

In the present embodiment, the connecting member 30 has an operation section 31 and a connection section 32 connected to each other. The operation section 31 may be disposed in the middle of the connection member 30, or may be disposed at the end of the connection member 30. In the present embodiment, the operation section 31 is provided at one end of the connection member 30, and the connection section 32 is provided at the other end of the connection member 30. Specifically, the outer surface of the operation section 31 is polygonal, the connection section 32 is provided with external threads, and the connection member 30 is in threaded connection with the bushing 50 through the connection section 32. In this embodiment, the inner hole of the bushing 50 is tapped using a tap to form an internal thread in the inner hole of the bushing 50, and then the connection member 30 is rotated through the operation section 31 using a special tool to screw-connect the connection section 32 with the bushing 50. In other embodiments, the operation section 31 may be disposed at the middle of the connection member 30, and the connection sections 32 may be disposed at both ends of the operation section 31, so that either end of the connection member 30 can be threadedly coupled to the bushing 50, thereby improving the ease of use of the device. In the present embodiment, the outer surface of the operation section 31 is hexagonal.

Specifically, the connecting member 30 has a first through hole 33, the first through hole 33 penetrates through the operation section 31 and the connection section 32, an internal thread is disposed in the first through hole 33, an external thread is disposed at the first end of the sliding rod 10, and the first end of the sliding rod 10 is in threaded connection with the first through hole 33.

In the present embodiment, the cross-sectional shape of the slider 20 is circular, and the slider 20 is specifically a cylinder. By providing the slider 20 as a cylinder, the operator can easily grip the slider 20 to slide the slider 20 between the first end and the second end of the slide bar 10. Also, gripping of the shoe 20 can be further facilitated by providing anti-slip structures, such as anti-slip grooves, on the outer surface of the shoe 20.

Wherein, the end corners of both ends of the slider 20 are provided with chamfers 21. When the sliding block 20 is held by hand, the chamfers 21 at the end feet of the two ends of the sliding block 20 can avoid cutting the hand of an operator, and the safety of the device can be improved while the operation is convenient.

The cross section of the sliding rod 10 is circular or polygonal, the sliding block 20 is provided with a second through hole, the sliding block 20 penetrates through the sliding rod 10 through the second through hole, and the cross section of the second through hole is matched with the cross section of the sliding rod 10 in shape. In the present embodiment, the cross section of the sliding rod 10 is circular, the cross section of the second through hole is circular, and the sliding rod 10 and the second through hole are in clearance fit.

In the present embodiment, the first limiting member 40 comprises a nut, and the second end of the sliding rod 10 is provided with an external thread. The threaded fit of the slider bar 10 and the nut may be achieved by threading the second end of the slider bar 10 into the nut. The structure can be realized by processing external threads at two ends of a polished rod and then connecting a nut with the polished rod in a thread fit mode, and the polished rod structure has the advantages of simple structure and low cost. In other embodiments, the first limiting member 40 may be configured as a limiting boss, and the limiting boss and the sliding rod 10 are integrally formed, so as to facilitate processing.

Specifically, the bushing removing device further includes a second limiting member, the second limiting member is disposed between the first limiting member 40 and the sliding rod 10, and the second limiting member is used for limiting a position of the first limiting member 40 on the sliding rod 10. In this embodiment, a small threaded hole is formed in an outer wall of the nut, the second limiting member is a limiting screw, the nut is rotated to a suitable position of the slide rod 10, and then the limiting screw is screwed into the small threaded hole, so that the limiting screw abuts against the slide rod 10 for limiting, and the position of the nut on the slide rod 10 can be limited. The second limiting member may also be a second nut, and the second nut is fixed to the slide bar 10 in a threaded fit manner and abuts against the nut (the first limiting member 40), so that the nut (the first limiting member 40) can be locked on the slide bar 10 by the second nut to limit the position of the nut (the first limiting member 40) on the slide bar 10.

In this embodiment, the surface of the bushing removing device is provided with a coating, so that the device can be prevented from being corroded, and the appearance of the device can be improved.

Specifically, the operation section 31 and the connection section 32 are in a stepped structure, and the outer diameter of the operation section 31 is larger than that of the connection section 32. When the connecting member 30 is screwed into the bushing 50 by using a special tool, if the connecting section 32 is completely screwed into the inner hole of the bushing 50, the side wall of the operating section 31 will abut against the bushing 50 or the swing arm, so that the connecting member 30 can be prevented from being screwed into the bushing 50 as a whole. In the present embodiment, the liner 50 is a graphite copper liner.

Through the device that this embodiment provided, when changing bush 50, at first according to the inside graphite copper bush's of swing arm internal diameter, utilize the screw tap supporting with the bush internal diameter to carry out the tapping to the bush, then be connected bush remove device and bush, operating personnel is with the hand constantly to nut direction drive slider 20, until pulling out the graphite copper bush of swing arm the inside, just so accomplished and dismantled graphite copper bush maintenance work. Furthermore, the connecting members 30 with different diameters can be selected according to the size of the inner hole of the bushing 50, so as to improve the application range of the device.
