After the propulsion cylinder on the side of the lower-layer discharging step feed channel (C) receives the control signal sent by the controller to control the moving bracket (5) on the side of the lower-layer discharging step feed channel (C) to move forward, the telescopic shaft of the propulsion cylinder on the side of the lower-layer discharging step feed channel (C) is shortened, so that the moving bracket (5) on the side of the lower-layer discharging step feed channel (C) moves forward; S56, when the shortening length of the telescopic shaft of the propulsion cylinder on the side of the lower-layer discharging step feed channel (C) is equal to the preset fifth shortening length threshold, the cam shaft (1) on the movable bracket (5) on the side of the lower-layer discharging step feed channel (C) is just above the corresponding groove of the fixed bracket (4) on the side of the lower-layer discharging step feed channel (C); that is, the groove of the movable bracket (5) on the side of the lower-layer discharging step feed channel (C) moves forward by an adjacent distance of one groove; S57, the controller sends a control signal to the lifting cylinder on the side of the lower layer discharging step feeding channel (C), and the control signal controls the moving bracket (5) on the side of the lower layer discharging step feeding channel (C) to move downward; After the lifting cylinder on the side of the lower-layer discharging step feeding channel (C) receives the control signal sent by the controller to control the downward movement of the movable bracket (5) on the side of the lower-layer discharging step feeding channel (C), the telescopic shaft of the lifting cylinder on the side of the lower-layer discharging step feeding channel (C) is shortened, so that the movable bracket (5) on the side of the lower-layer discharging step feeding channel (C) moves downward; S58, when the shortening length of the telescopic shaft of the lifting cylinder on the side of the lower-level discharging step feed channel (C) is equal to the preset sixth shortening length threshold, the height of the movable bracket (5) on the side of the lower-level discharging step feed channel (C) is lower than the fixed bracket (4) on the side of the lower-level discharging step feed channel (C), and the movable bracket (5) on the side of the lower-level discharging step feed channel (C) is in a reset state; the cam shaft (1) is lifted by the fixed bracket (4) on the side of the lower-level discharging step feed channel (C) and is located on the corresponding groove.

5. The camshaft detection and classification working method according to claim 1, characterized in that: The method in which the vertical moving member (9) moves the unqualified camshaft (1) to the lower discharge step feed channel (C) in step S5 comprises the following steps: S5-1, the controller sends a control signal to the servo motor, the control signal is for controlling the camshaft bracket (7) to move downward; After the servo motor receives the control signal from the controller to cause the camshaft bracket (7) to move downward, the servo motor rotates forward to cause the camshaft bracket (7) to move downward; S5-2, when the number of forward rotations of the servo motor is equal to the preset forward rotation number threshold, the height of the camshaft bracket (7) is equal to the fixed bracket (4) on the side of the lower discharge step feed channel (C); S5-3, after the camshaft (1) on the camshaft bracket (7) is transported away by the lower discharge step feed channel (C), the next step is executed; S5-4, the controller sends a control signal to the servo motor, the control signal is used to control the camshaft bracket (7) to move upward; After the servo motor receives the control signal from the controller to control the camshaft bracket (7) to move upward, the servo motor reverses to cause the camshaft bracket (7) to move upward; S5-2, when the number of positive rotations of the servo motor is equal to the preset threshold value of the number of reverse rotations, the height of the camshaft bracket (7) is equal to the fixed bracket (4) on the side of the upper discharge step feed channel (B), and the camshaft bracket (7) is in a reset state.
