[0030] like Figure 1 and Figure 2 As shown, further, each placement tube 301 is provided with a fixing rod 105 between each pair. In this arrangement, it is ensured that when one placement tube 301 moves, other placement tubes 301 can be driven to move.

[0031] The implementation principle of the output shaft cutting device for motor production in this embodiment is as follows: First, the staff places the output shaft air intake used in the motor production process on the two arc-shaped placement tables 104 arranged above the workbench 102. When the placement is completed, the moving rod 1043 arranged above the arc-shaped placement table 104 will be able to move downward under the gravity of the motor output shaft. When the moving rod 1043 moves downward, it will be able to 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 will be able to pull the fixed 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 slide groove 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 and the first slider 1022 are fixedly connected), so that the clamping plate 3044 can squeeze, clamp and limit the placed motor output shaft; 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 that the motor output shaft to be cut can 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 (wherein the cutting assembly 2015 is specifically used in the prior art); When the positioning block 2014 moves vertically downward, it can drive the special-shaped plate 203 and the circular mounting plate 2027 to move vertically downward. When the circular mounting plate 2027 moves vertically downward, the circular mounting plate 2027 will be able to be inserted into the placement tube 301. Because the elastic force of the first return spring 2025 in the inner cavity of the rectangular tube 2021 is greater than the elastic force of the second return spring 3016 in the inner cavity of the placement tube 301, the circular mounting plate 2027 will be able to squeeze the limit plate 3014 set in the placement tube 301 and move vertically downward with the assistance of the third slide groove 3012 and the third slider 3013. At the same time, the circular mounting plate 2027 will be able to squeeze the tilting block 303 and move horizontally with the assistance of the third slide rail 3034. When the tilting block 303 moves, it will be able to drive the second moving plate 3031 to move horizontally.
