The two rectangular cylinders 2021 are symmetric with each other. A second sliding mechanism is arranged in the inner cavity of the two rectangular cylinders 2021. A sliding rod 2026 is connected to the second sliding mechanism. Return-shaped mounting plates 2027 are installed at the ends of the two sliding rods 2026 away from the second sliding mechanism respectively;The locking and clamping unit 300 includes a plurality of placement cylinders 301, each pair of the placement cylinders 301 being symmetric to each other. On one side wall of each pair of the placement cylinders 301 facing each other, a placement block 302 is installed. A fourth sliding mechanism and a guiding mechanism are arranged in the inner cavity of each placement block 302. A placement notch 3011 is formed above each placement cylinder 301. A third sliding mechanism is arranged in the inner cavity of each placement cylinder 301, and an inclined block 303 is arranged on one side wall of the third sliding mechanism.

[0037] When the square mounting plate 2027 moves vertically downward, the square mounting plate 2027 will be able to be inserted into the placing cylinder 301 at this time. Because the elastic force of the first return spring 2025 in the inner cavity of the rectangular cylinder 2021 is greater than the elastic force of the second return spring 3016 in the inner cavity of the placing cylinder 301, the square mounting plate 2027 will be able to squeeze the limiting plate 3014 arranged in the placing cylinder 301 to move vertically downward with the assistance of the third sliding groove 3012 and the third sliding block 3013.

When the second moving plate 3031 moves, it will be able to drive the connecting plate 3032 to move, so as to drive the rectangular insertion rod 3041 to squeeze the partition plate 3051 to move horizontally with the assistance of the second sliding rail 305 arranged in the inner cavity of the rectangular mounting cylinder 304 until the notch opened in the middle of the square mounting plate 2027 is located in the inclined block 303. And at this time, the square mounting plate 2027 continues to move downward, so that the inclined block 303 can be squeezed against the inner wall of the placing cylinder 301. At this time, the limiting plate 3014 is in contact with the bottom of the placing cylinder 301. And at this time, the placing plate 202 continues to move downward, so that the square mounting plate 2027 can squeeze the sliding plate 2024 to be in a stationary state with the assistance of the second sliding groove 2022 and the second sliding block 2023. When the square mounting plate 2027 is in a stationary state, the special-shaped plate 203 will be able to contact the side wall of the inclined plate 3045 fixedly installed on the clamping plate 3044, so as to drive the inclined plate 3045 to drive the clamping plate 3044 to move, so as to loosen the clamping of the motor output shaft, and then cut the motor output shaft through the cutting assembly 2015.

[0046] As Figure 1 and Figure 2 shown, further, fixing rods 105 are installed between every two placement cylinders 301. In this setting, it is ensured that when one placement cylinder 301 moves, it can drive other placement cylinders 301 to move.

[0047] The implementation principle of an output shaft cutting device for motor production in this embodiment is as follows:

[0048] First, the staff places the output shaft used in the motor production process on the two arc-shaped placement platforms 104 arranged above the workbench 102. When the placement is completed, since the moving rod 1043 arranged above the arc-shaped placement platform 104 can move downward under the gravity of the motor output shaft, when the moving rod 1043 moves downward, it can drive the first moving plate 1042 to move vertically downward with the assistance of the first slide rail 1041. When the first moving plate 1042 moves vertically downward, it can drive the fixing plates 1046 on both sides through the movable rod 1045 to drive the placement cylinder 301 to move horizontally with the assistance of the first chute 1021 and the first slider 1022 in the first sliding mechanism (because a placement block 302 is installed on one side of the placement cylinder 301 and the placement block 302 is fixedly connected to the first slider 1022), so that the clamping plate 3044 can squeeze and clamp the placed motor output shaft for limit;

[0049] At this time, the staff controls the electric slide rail 103 to drive the hydraulic cylinder 201 to move, so that the position of the cutting assembly 2015 can be adjusted, so as to cut the motor output shaft to be cut at a precise position. When the position adjustment is completed, the staff starts the hydraulic cylinder 201, so that the hydraulic cylinder 201 can push the connecting plate 2011 to drive the connecting rod 2012 to move vertically downward. When the connecting rod 2012 moves vertically downward, it can drive the positioning block 2014, the side wall plate 2013, the concave plate 2016 and the cutting assembly 2015 to move vertically downward (where the cutting assembly 2015 is a specific use of the prior art);

[0050] When the positioning block 2014 moves vertically downward, it can drive the special-shaped plate 203 and the loop-shaped mounting plate 2027 to move vertically downward. When the loop-shaped mounting plate 2027 moves vertically downward, it will be able to be inserted into the placing cylinder 301. Since the elastic force of the first return spring 2025 in the inner cavity of the rectangular cylinder 2021 is greater than the elastic force of the second return spring 3016 in the inner cavity of the placing cylinder 301, the loop-shaped mounting plate 2027 will be able to squeeze the limiting plate 3014 arranged in the placing cylinder 301 to move vertically downward with the assistance of the third chute 3012 and the third slider 3013. At the same time, the loop-shaped mounting plate 2027 will be able to squeeze the inclined block 303 to move horizontally with the assistance of the third slide rail 3034. When the inclined block 303 moves, it will be able to drive the second moving plate 3031 to move horizontally.
