[0029] By setting the micro electric push rod 204, since the inner diameters of bushings of different models are different, when it is necessary to install a bushing with a larger inner cavity onto the surface of the limiting piece 205, firstly, the inner cavity of the bushing is inserted into the surface of the limiting piece 205, and then the micro electric push rod 204 is started, and the output rod of the micro electric push rod 204 drives the four limiting pieces 205 to move, so that the surface of the limiting piece 205 is pressed against the inner cavity surface of the bushing. Since the limiting piece 205 is semicircular, it can be more closely fitted to the surface of the inner cavity of the bushing when pressed;

[0030] By setting the mounting plate 201, four groups of connecting columns 203 and limiting plates 205 are installed on the top of the mounting plate 201. When installing the bushing, four bushings can be installed at the same time. When the edge trimming of one bushing is completed, the first motor 2 will drive the mounting plate 201 to rotate a certain angle, so that the next bushing that has not been trimmed is under the tool 304 for trimming. In this way, the four bushings can be trimmed at the same time, thereby improving the trimming efficiency.

[0031] By providing the second motor 202 , after the bushing is fixed, the second motor 202 can be started to drive the bushing to rotate, so that the tool 304 can perform edge cutting.

[0032] Embodiment 2

[0033] On the basis of the first embodiment, the edge trimming mechanism includes a mounting bracket 3, a first threaded rod 301, a third motor 302, a sliding block 303 and a tool 304. The mounting bracket 3 is installed on one side of the top of the bottom plate 1. The mounting bracket 3, the inner cavity of the mounting bracket 3 is installed with the first threaded rod 301, the top of the mounting bracket 3 at one end of the first threaded rod 301 is installed on the third motor 302, the surface of the first threaded rod 301 is installed with a sliding block 303, and the inner cavity of the sliding block 303 is installed with a tool 304;

[0034] By setting the tool 304, when the bushing is installed and fixed on the outside, the user first rotates the second threaded rod 501 to adjust the position of the tool 304 so that the tool 304 is above the bushing that needs to be chamfered. At this time, the third motor 302 is started, and the third motor 302 drives the first threaded rod 301 to rotate. The rotation of the first threaded rod 301 drives the sliding block 303 and the tool 304 to move downward. Since the second motor 202 can drive the bushing to rotate, the tool 304 contacts the surface of the bushing at this time, and the bushing can be chamfered.

[0035] Embodiment 3

[0036] On the basis of the first embodiment, the limit assembly includes a support frame 4, an electric push rod 401 and a cross plate 402. The support frame 4 is installed on the rear surface of the bottom plate 1, the electric push rod 401 is installed on the top of the inner cavity of the support frame 4, and the cross plate 402 is installed on one end of the output shaft of the electric push rod 401;

[0037] By setting the cross plate 402, when the user installs the bushing on the surface of the limiting plate 205 and fixes it, the electric push rod 401 is started, and the output rod of the electric push rod 401 drives the cross plate 402 to move downward, so that the pressure block at the bottom end of the cross plate 402 contacts the top of the bushing and presses the bushing to limit its position, thereby improving the stability of the bushing during chamfering. Since a shaft is set at one end of the pressure block, when the bushing rotates, the pressure block will rotate with the bushing. At the same time, a shaft is also set at the top of the cross plate 402. When the mounting plate 201 is rotated to adjust the angle, the cross plate 402 will also rotate accordingly.

[0038] Embodiment 4

[0040] By setting the second threaded rod 501, the rotating rocker 502 can drive the second threaded rod 501 to rotate. The rotation of the second threaded rod 501 can drive the connecting block 503 to move left and right. The left and right movement of the connecting block 503 can drive the tool 304 to move left and right, so that the tool 304 can chamfer bushings with different diameters.

[0041] Embodiment 5

[0042] On the basis of the first embodiment, a screw rod 6 is installed in the inner cavity of the support column 101, and a base 601 is installed at one end of the screw rod 6;

[0043] By setting the screw 6, rotating the screw 6 can drive the base 601 to move up and down, so as to adjust the height of the base plate 1. At the same time, the heights of the four bases 601 can be adjusted four times in turn according to the ground level, so as to adjust the level of the base plate 1. At the same time, a gasket is also set at one end of the base 601, and the gasket is made of rubber, which can play an anti-slip and vibration reduction effect.

[0044] Embodiment 6

[0045] On the basis of the second embodiment, a fixed knob 7 is installed at the top of the sliding block 303, and one end of the fixed knob 7 extends to the top of the tool 304;

[0046] By setting the fixing knob 7, the fixing knob 7 is mainly used to fix the tool 304. The tool 304 and the inner cavity of the sliding block 303 can be disassembled by loosening the fixing knob 7, and the tool 304 can be replaced or polished.

[0047] Embodiment 7

[0048] On the basis of the second embodiment, a control panel 8 is installed on the other side of the top of the bottom plate 1;

[0049] By setting the control panel 8, the control panel 8 is mainly used for starting and stopping the first motor 2, the second motor 202, the micro electric push rod 204, the third motor 302 and the electric push rod 401.

[0050] When the utility model is in use, firstly, four bushings are sequentially placed into the surfaces of four groups of connecting columns 203 and limiting plates 205. When the inner cavity of the bushing is larger than the surface of the limiting plates 205, the micro electric push rod 204 is started, and the output rod of the micro electric push rod 204 drives the four limiting plates 205 to move, so that the surface of the limiting plates 205 is pressed against the inner cavity surface of the bushing. When the bushing is fixed, the electric push rod 401 is started, and the output rod of the electric push rod 401 drives the cross plate 402 to move downward, so that the pressure block at the bottom end of the cross plate 402 contacts the top end of the bushing and presses the bushing to limit its position, and the second screw is rotated. The threaded rod 501 adjusts the position of the tool 304 so that the tool 304 is above the bushing that needs to be chamfered. At this time, the third motor 302 is started, and the third motor 302 drives the first threaded rod 301 to rotate. The rotation of the first threaded rod 301 drives the sliding block 303 and the tool 304 to move downward. Since the second motor 202 can drive the bushing to rotate, the tool 304 contacts the surface of the bushing at this time, and the bushing can be chamfered. After the first bushing is chamfered, the first motor 2 will drive the mounting plate 201 to rotate a certain angle, so that the next un-chamfered bushing is below the tool 304 for chamfering.
