after the rotor support 4 is inserted into the placing box 2, the pushing component is controlled to work, and the working hydraulic cylinder 40 pushes the placing box 2 to move towards the motor rotor 39, so that the rotor support 4 in the placing box 2 is sleeved towards one end of the outer side of the motor rotor 39. Finally, two support bearings 5 fixedly connected inside the rotor support 4 are sleeved at one end of the outer side of the motor rotor 39 under the condition of interference fit, and the motor rotor support and the motor rotor 39 formed by the rotor support 4 and the two support bearings 5 are installed.
In the working process of the hydraulic cylinder 40, the water pump 3 synchronously works for a period of time, and the length of the oil supply pipe fixed by the water pump 3 has sufficient allowance, so that the requirement of synchronous movement of the water pump 3 and the placement box 2 is met. The water pump 3 works and infuses lubricating oil into the insertion pipe 8 through the connecting pipe 9, after the lubricating oil enters the threaded groove 7 through the insertion pipe 8, the lubricating oil enters between the two support bearings 5 under the guidance of the guide holes 6, the lubricating oil is smeared on the two support bearings 5, and the abrasion of the motor rotor 39 when the motor rotor bracket formed by the rotor bracket 4 and the two support bearings 5 is sleeved outside the motor rotor 39 is reduced.
And lubrication maintenance is completed in the installation process of the motor rotor bracket and the motor rotor 39, so that the investment of the processing cost of the motor rotor bracket is reduced, and the damage of the rotor bracket 4 to the motor rotor 39 is reduced.
Referring to fig. 1, 9, 12 and 13 again, V-shaped grooves 11 are formed on two sides of the discharging frame 10, two ends of a motor rotor 39 are respectively disposed inside the two V-shaped grooves 11, a clamping block 12 is disposed inside the supporting seat 1 and is fixedly connected to the bottom of the discharging frame 10, a rubber sleeve 13 is fixedly connected inside the clamping block 12, an inserting rod 14 is disposed inside the rubber sleeve 13, the inserting rod 14 is fixedly connected to one end of a pressure sensor 15, the pressure sensor 15 is fixedly connected to one end of a first pneumatic cylinder 16, the first pneumatic cylinder 16 is fixedly connected to the bottom of the supporting seat 1, and the supporting frame is disposed between the clamping assembly and the pushing assembly.
Specifically, the support frame work details are as follows:
the motor rotor 39 is placed on the discharging frame 10, so that two ends of the motor rotor 39 are respectively arranged inside the two V-shaped grooves 11, and at the moment, the motor rotor 39 and the discharging frame 10 are in a line contact state, and abrasion of the motor rotor 39 in the rotating process is reduced.
The first pneumatic cylinder 16 working pushes the pressure sensor 15 to move, after the inserted rod 14 fixed by the pressure sensor 15 is inserted into the rubber sleeve 13, one side of the pressure sensor 15 contacts with the clamping block 12 to push the clamping block 12, so that the clamping block 12 drives the discharging frame 10 to move towards the clamping box 17, and finally one end of the motor rotor 39 is inserted into the clamping assembly. The supporting seat 1 top is offered flutedly, and the fixture block 12 bottom runs through the recess and constitutes sliding connection relation with supporting seat 1, places case 2 bottom simultaneously and sets up in the recess inside, increases to place the area of contact between case 2 and the supporting seat 1, improves and places case 2 motion stability.
When the discharging frame 10 contacts with the clamping box 17, the pressure received by the pressure sensor 15 is increased suddenly, the first pneumatic cylinder 16 is controlled to stop working at the moment, the clamping assembly stops working after the motor rotor 39 finishes processing, the motor rotor 39 can move left and right, and the first pneumatic cylinder 16 is controlled to drive the inserted link 14 to reset at the moment.
Because of the large static friction between the inserted link 14 and the rubber sleeve 13, the inserted link 14 drives the clamping block 12 to synchronously reset through the rubber sleeve 13, and pulls one end of the motor rotor 39 to leave the inside of the clamping assembly. The insert rod 14 and the clamping block 12 are designed in a detachable manner, so that the discharging frame 10 can be quickly replaced, and the requirements of machining motor rotors 39 with different sizes on the top of the supporting seat 1 are met.

Specifically, when the hydraulic pressure between the storage tank 21 and the seal ring 22 increases, the piston 30 in the piston cylinder 29 moves under the pushing of the liquid, and the piston 30 pushes the friction plate 31 to move to contact with one end of the motor rotor 39, so as to clamp and fix one end of the motor rotor 39. When the hydraulic pressure in the storage tank 21 and the seal ring 22 is restored, the friction plate 31 and the piston 30 are restored under the action of negative pressure, so that one end of the motor rotor 39 loses the fixing effect.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
