The working end of the vertical driving cylinder 35 passes through the movable plate 33 and is fixedly connected with the transverse sliding frame 32 so as to drive the movable plate 33 to vertically move above the transverse sliding frame 32. The drive motor 34 acts on the drive shaft assembly 36 to rotate the rollers 36a attached to the ends of the drive shaft assembly 36. The roller 36a is connected with the movable plate 33, the surface of the roller 36a can be abutted against the shaft part of the rotor shaft A1 through regulating the first driving cylinder 31b and the vertical driving cylinder 35, the rotor shaft A1 is driven to rotate at the sheet metal bracket 38a through friction, and therefore the outer surface of the rotor shaft A1 can be continuously and completely processed correspondingly in the processing cavity 38.

As shown in fig. 5, the four-bar linkage 37 includes a second driving cylinder 37', a first link 37a, a second link 37b, a third link 37c, a base plate 37f, and an operating arm 37g. The second driving cylinder 37' is hinged and fixed with one end of the second connecting rod 37b and the third connecting rod 37c through a first hinge shaft 37 d; the other end of the third link 37c is hinged and fixed with one end of the first link 37a through a second hinge shaft 37 e; the other end of the first link 37a is hinged and fixed on the surface of the platform through a third hinge shaft 37 h; the other end of the second link 37b is hinged and fixed to the platform surface through a fourth hinge shaft 37 k; the first link 37a is parallel to the second link 37 b; the base plate 37f is fixed at both ends to the first hinge shaft 37d and the second hinge shaft 37e, respectively, so that the base plate 37f is parallel to the third link 37 c; the working arm 37g is fixed to one side of the base plate 37f, and the front end of the working arm 37g extends to the sheet metal bracket 38a. When the second driving cylinder 37' is in an extending state, the first hinge shaft 37d is stretched to move to the right, so that the top hinge point of the second connecting rod 37b and the third connecting rod 37c are driven to move to the right, and then the top hinge point of the first connecting rod 37a is driven to move to the right, so that the second hinge shaft 37e synchronously moves to the right, the base plate 37f is far away from the sheet metal bracket 38a, and the front end of the working arm 37g at the moment is just positioned near the supporting position of the sheet metal bracket 38a. After the surface treatment of the rotor shaft a1 is completed, the second driving cylinder 37' contracts to drive the first hinge shaft 37d to move left, so as to drive the top hinge point of the second link 37b and the third link 37c to move left, and further to transmit to the top hinge point of the first link 37a, so that the second hinge shaft 37e synchronously moves left, so as to move the base plate 37f toward the sheet metal bracket 38a, and in the process, the front end of the working arm 37g moves obliquely upward to be connected with the shaft portion of the rotor shaft a1, so as to take out the rotor shaft a1 from the sheet metal bracket 38a, and finally convey the rotor shaft a1 to the blanking chute 39.

The blanking chute 39 includes a first blanking frame 39a and a second blanking frame 39b. The first discharging rack 39a is connected to a first adjusting mechanism 39a ', and the second discharging rack 39b is connected to a second adjusting mechanism 39 b'. When the first adjusting mechanism 39a 'and/or the second adjusting mechanism 39 b' are operated, the first blanking frame 39a can move relative to the second blanking frame 39b so that the width of the blanking chute 39 formed by them can be adjusted to match the width of the accommodating space 10c at the supporting table 10.

When the assembling platform provided by the assembling platform is used for detecting the rotor shaft, the rotor shaft is fed to the accommodating space of the supporting table. The rotor shaft is conveyed to the fixed seat by the conveying frame of the conveying mechanism, so that the shaft rod part of the rotor shaft is arranged in the fixed groove of the fixed seat and is fixed along the axial direction under the combined action of the fixed limit stop and the movable limit stop. And then, the pushing cylinder drives the pushing pressing die to move back to abut against the pressing block, so that the clamping piece sleeved at the guide bar of the clamping piece is fed into the pushing pressing die from a material channel formed in the main body part of the fixing seat under the action of the pressing block. The pushing cylinder drives the pushing pressing die to horizontally move towards the rotor shaft rod part, the clamping piece in the pushing pressing die is pushed into the rotor shaft rod part, the clamping piece is clamped and fixed at a specific position of the rotor shaft rod part, the assembling operation of the rotor shaft clamping piece is completed, and the pushing cylinder drives the pushing pressing die to retract to the starting position. The clamping jaw of the transferring unit slides to the fixed seat to downwards clamp the rotor shaft, after the rotor shaft is lifted, the clamping part assembly unit in the platform is clamped to the sheet metal support of the transferring unit under the driving of the sliding seat, so that the shaft rod part of the rotor shaft is respectively supported at the top roller of the sheet metal support, and the clamping jaw is retracted to the starting position. The first driving cylinder and the vertical driving cylinder respectively regulate and control the spatial positions of the transverse sliding frame and the movable plate, so that the surface of the roller can be in compression joint with the shaft part of the rotor shaft between the metal plates. The driving motor and the transmission shaft assembly drive the roller to rotate, so that the rotor shaft rotates along with the rotor shaft due to the friction action. The working end of the cleaning, detecting or finishing device arranged in the processing cavity can continuously and stably process the outer surface of the rotor shaft in the rotating process of the rotor shaft, so that the reliable performance of the rotor shaft is ensured before the motor is assembled. And then, the second driving cylinder works to drive the four-bar mechanism to deform, so that the working arm extracts the rotor shaft in the sheet metal support and sends the rotor shaft to the discharging slideway to finish discharging.
