Once the stator assembly of the motor is assembled into the motor housing 600, the assembly of the rotor assembly is performed, and the motor housing 600 and the stator assembly may be placed on the tooling pallet 300. The tooling pallet 300 may be provided with a pin rod for plugging and supporting the motor housing 600, so that the motor housing 600 may be stably placed on the tooling pallet 300. The tooling pallet 300 may be moved over the pallet string 400 to move the motor housing 600 and stator assembly to below the rotor assembly. When the motor housing 600 is moved into place, the motor rotor assembly in-box auxiliary assembly equipment assembles the rotor assembly into the stator assembly to complete the in-box process of the motor rotor assembly.

As shown in fig. 3, in the embodiment, when the tooling pallet 300 moves in place on the pallet line body 400, the tooling pallet 300 and the motor housing 600 disposed on the tooling pallet 300 may be fixed by the motor housing fixing device, so that the motor housing 600 may be kept stable, and thus the rotor assembly may be conveniently and accurately inserted into the stator assembly. In detail, the jacking mechanism 100 may pass through the tray wire 400 in the vertical direction. When the tooling pallet 300 is blocked by the pallet blocking cylinder 500 and stops moving, the jacking mechanism 100 can drive the tooling pallet 300 to move upwards in the vertical direction so as to jack up and lift the tooling pallet 300 off the pallet line body 400; and the pressing rod mechanism 200 rotates the limiting pressing rod 210 thereof to press the motor housing 600 on the tooling pallet 300. The jacking mechanism 100 and the compression bar mechanism 200 may both be provided on the frame 700.

When the rotor assembly is assembled, the pressing bar mechanism 200 rotates the limiting pressing bar 210 again to cancel the pressing action on the motor housing 600, and then the jacking mechanism 100 drives the tooling pallet 300 to move downwards along the vertical direction to replace the tooling pallet 300 on the pallet wire 400, and the pallet blocking cylinder 500 is switched to the second gear, so that the tooling pallet 300 can move on the pallet wire 400 continuously to move the motor housing 600 assembled with the rotor assembly downwards continuously for the next assembly process.

It can be appreciated that, according to the utility model, the tool tray 300 and the motor housing 600 arranged on the tool tray 300 are jacked up and lifted away from the tray wire body 400 by the jacking mechanism 100, so that the tool tray 300 can be prevented from shaking due to the driving force of the tray wire body 400; the motor shell 600 is pressed on the tooling pallet 300 through the limiting pressing rod 210, so that the motor shell 600 can be prevented from shaking on the tooling pallet 300 due to interaction force between the motor shell 600 and the rotor assembly, and the stability of the motor shell 600 in the process of putting the rotor assembly into the box can be ensured, and the influence on the accuracy of the position of the rotor assembly in the process of putting the rotor assembly into the box due to shaking is avoided.

The plunger drive assembly 240 may be provided as an electric cylinder and includes an electric cylinder seat 241 and a piston rod 242. The electric cylinder block 241 may be disposed on the first fixing plate 221 and directly under the third fixing plate 223.

The rotation seat 230 may be disposed on the third fixing plate 223 and rotatably coupled with the rotation coupling member 250, and the rotation coupling member 250 is further coupled with the middle portion of the limit plunger 210. The other end of the limit pressing lever 210 extends in a direction approaching the tray wire body 400 and is used to abut against the motor housing 600.

As shown in fig. 2, in the present embodiment, before the tooling pallet 300 and the motor housing 600 disposed on the tooling pallet 300 move to a position directly below the rotor assembly, the piston rod 242 of the press rod driving assembly 240 moves downward in the vertical direction to drive the limiting press rod 210 and the rotating connecting member 250 to rotate around the rotating connecting member 250 and the rotating seat 230, and one end of the limiting press rod 210 away from the piston rod 242 rotates away from the pallet line 400, so as to avoid interference of the limiting press rod 210 on the movement of the tooling pallet 300 on the pallet line 400.

As shown in fig. 3, when the tooling pallet 300 moves in place and the jacking mechanism 100 lifts the tooling pallet 300 away from the pallet wire 400, the piston rod 242 of the press rod driving assembly 240 moves upward in the vertical direction to drive the limiting press rod 210 and the rotating connecting member 250 to rotate around the rotating connecting member 250 and the rotating seat 230, and one end of the limiting press rod 210 away from the piston rod 242 rotates to be close to the pallet wire 400, so as to press the motor housing 600 on the tooling pallet 300.

More specifically, the rotation link 250 is rotatably coupled to the middle portion of the limit plunger 210.

As shown in fig. 1 and 2, in the present embodiment, it is exemplarily illustrated that both ends of the rotation link 250 may be provided with an open groove 251, and the middle portion of the limit plunger 210 and the top end of the rotation seat 230 extend into the open groove 251 and are rotatably connected with the rotation link 250. When the lever driving assembly 240 drives the limiting lever 210 and the rotating connecting member 250 to rotate around the rotating connection of the rotating connecting member 250 and the rotating seat 230, the limiting lever 210 can also rotate around the rotating connection of the limiting lever and the rotating connecting member 250.

More specifically, an elastic portion 211 is disposed at an end of the limiting plunger 210 for abutting against the motor housing 600, and the limiting plunger 210 abuts against the motor housing 600 through the elastic portion 211.

As shown in fig. 1 and 3, in the present embodiment, it is exemplarily illustrated that the end of the limit plunger 210 that abuts against the motor housing 600, that is, the end of the limit plunger 210 that is away from the piston rod 242, the elastic portion 211 is disposed on the end.

Specifically, the two groups of compression bar mechanisms 200 are provided, the two groups of compression bar mechanisms 200 are oppositely arranged at two sides of the tray line body 400, and the two groups of compression bar mechanisms 200 are also respectively arranged at two ends of the tooling tray 300 along the extending direction of the tray line body 400.

As shown in fig. 1 and 3, in the present embodiment, it is exemplarily described that the extending direction of the tray wire 400 is the axis thereof as seen from the direction of looking down the tray wire 400. The two groups of compression bar mechanisms 200 are symmetrically arranged along a longitudinal section passing through the axis of the tray wire body 400 and are respectively arranged at two sides of the tray wire body 400, so that when the tooling pallet 300 moves in place and the jacking mechanism 100 lifts the tooling pallet 300 up the tray wire body 400, the motor housing 600 is compressed from two sides of the tooling pallet 300. Meanwhile, along the extending direction of the tray wire body 400, two groups of compression bar mechanisms 200 are further respectively arranged at two ends of the tooling tray 300, so as to compress the motor housing 600 from two ends of the tooling tray 300.

Specifically, the jacking mechanism 100 includes a jacking driving assembly 110 and a jacking plate 120, where the jacking plate 120 is slidably disposed along a vertical direction and is connected to the jacking driving assembly 110, and the jacking driving assembly 110 is configured to drive the jacking plate 120 to move upwards along the vertical direction when the tooling pallet 300 is stopped by the pallet blocking cylinder 500 so as to be abutted to the tooling pallet 300.

As shown in fig. 1 and 3, in the present embodiment, it is exemplarily illustrated that the jacking plate 120 may be provided in a rectangular shape, and a length direction thereof may be an extending direction of the tray wire body 400. The jacking plate 120 is slidably disposed on the frame 700 in a vertical direction and is driven by the jacking drive assembly 110. The jacking driving assemblies 110 may be provided as cylinders, and four groups of jacking driving assemblies 110 may be provided at four corners of the jacking plate 120, respectively, to smoothly drive the jacking plate 120 to move.

In this embodiment, after the pallet blocking cylinder 500 stops moving the tooling pallet 300, the piston end 112 of the jacking driving assembly 110 moves upward in the vertical direction, so as to drive the jacking plate 120 to move upward synchronously in the vertical direction. When the jacking plate 120 moves to abut against the tooling pallet 300, the tooling pallet 300 is driven to move upwards synchronously along the vertical direction, so as to lift the top of the tooling pallet 300 and lift the pallet line body 400. When the rotor assembly is assembled, the piston end 112 moves downward in the vertical direction to drive the jacking plate 120 and the tooling pallet 300 to move downward synchronously in the vertical direction, and the tooling pallet 300 moves to a position re-abutting against the pallet wire 400.

It can be appreciated that, in this embodiment, by setting the jacking driving assembly 110 and the jacking plate 120, and driving the jacking plate 120 to abut against the tooling pallet 300 through the jacking driving assembly 110, the tooling pallet 300 can be driven to move synchronously through the jacking plate 120, so as to achieve the purpose of lifting the tooling pallet 300 away from the pallet wire body 400.

More specifically, the jacking mechanism 100 further includes a tray positioning pin 130, where the tray positioning pin 130 is disposed on a top side of the jacking plate 120, and a positioning pin hole 310 is disposed on a bottom side of the tooling pallet 300, and the tray positioning pin 130 is used to extend into the positioning pin hole 310 when the jacking plate 120 abuts against the tooling pallet 300.

As shown in fig. 1 and 4, in the present embodiment, it is exemplarily illustrated that the tray positioning pins 130 may be provided at a top side of the jacking plate 120, which may be detachably connected with the jacking plate 120 by means of a bolt member, so as to be easily replaced. Correspondingly, the positioning pin hole 310 may be provided as a bottom side of the tooling pallet 300 for the pallet positioning pin 130 to extend into. When the jacking driving assembly 110 drives the jacking plate 120 to move in the vertical direction, the tray positioning pins 130 move upward in synchronization in the vertical direction to approach the positioning pin holes 310 and gradually extend into the positioning pin holes 310. When the jacking plate 120 is abutted against the tooling pallet 300, the pallet positioning pins 130 extend completely into the positioning pin holes 310.

It can be appreciated that, in this embodiment, by setting the tray positioning pins 130 on the jacking plate 120 and setting the corresponding positioning pin holes 310 on the tooling pallet 300, when the jacking plate 120 is abutted against the tooling pallet 300, the jacking plate 120 can be positioned by extending the tray positioning pins 130 into the positioning pin holes 310, so as to improve the accuracy of the position when the jacking plate 120 jacks up the tooling pallet 300 and lifts away from the pallet wire body 400.

The guide 131 is provided in a tapered shape, i.e., with an outer diameter gradually decreasing, as it extends upward in the vertical direction. Correspondingly, the guide hole 311 may be a counter bore structure in a shape of a revolving body, and the axis thereof is also vertically arranged. The guide hole 311 is provided in a diverging shape, i.e., with an inner diameter gradually increasing, as it extends downward in the vertical direction.

As shown in fig. 1 and 4, in the present embodiment, it is exemplarily illustrated that two positioning pin holes 310 are provided at both sides of the jacking plate 120, that is, at both sides of the jacking plate 120 in the width direction, respectively, and at both ends of the jacking plate 120 in the extending direction of the tray wire body 400, that is, at both ends of the jacking plate 120 in the length direction, respectively. In this embodiment, the tooling pallet 300 may also be rectangular, and the length direction thereof may be the extending direction of the pallet string body 400. Correspondingly, the two positioning pin holes 310 may be respectively disposed at two sides of the tooling pallet 300 in the width direction, and at two ends of the tooling pallet 300 in the length direction, and correspond to the two pallet positioning pins 130 one by one.

The implementation principle of the motor shell fixing device provided by the embodiment of the utility model is as follows:

after the stator assembly of the motor is assembled to the motor housing 600 of the motor, the motor housing 600 is placed on the tooling pallet 300. At the same time, the rotor assembly is fed directly above the frame 700. The tooling pallet 300 moves on the pallet line body 400, and at this time, the piston rod 242 of the pressure rod driving assembly 240 moves downward along the vertical direction, so as to drive the limiting pressure rod 210 and the rotating connecting piece 250 to rotate around the rotating connecting piece 250 and the rotating seat 230, and meanwhile, the limiting pressure rod 210 can also rotate around the rotating connecting piece 250, so that one end of the limiting pressure rod 210, which is far away from the piston rod 242, rotates away from the pallet line body 400, and interference caused by the limiting pressure rod 210 to the movement of the tooling pallet 300 on the pallet line body 400 is avoided. When the tooling pallet 300 and the motor housing 600 move to the position right below the rotor assembly, the piston end 112 of the jacking driving assembly 110 moves upwards in the vertical direction, so as to drive the jacking plate 120 to synchronously move upwards in the vertical direction. At this time, the tray positioning pins 130 approach and gradually extend into the positioning pin holes 310, and when the jacking plate 120 abuts against the tooling tray 300, the tray positioning pins 130 completely extend into the positioning pin holes 310, and the jacking plate 120 is kept fixed on the tooling tray 300. The tooling pallet 300 moves upward synchronously with the jacking plate 120 in the vertical direction to be jacked up by the jacking plate 120 and away from the pallet line 400. Then, the piston rod 242 of the compression bar driving assembly 240 moves upward along the vertical direction to drive the limiting compression bar 210 and the rotating connecting piece 250 to rotate around the rotating connecting piece 250 and the rotating seat 230, and the end of the limiting compression bar 210 away from the piston rod 242 rotates to be close to the tray line 400, so as to abut the elastic part 211 against the motor housing 600, and further press the motor housing 600 on the tool tray 300.

According to the utility model, the tool tray 300 and the motor shell 600 arranged on the tool tray 300 are jacked up and lifted away from the tray line body 400 by the jacking mechanism 100, so that the tool tray 300 can be prevented from shaking due to the driving force of the tray line body 400; the motor shell 600 is pressed on the tooling pallet 300 through the limiting pressing rod 210, so that the motor shell 600 can be prevented from shaking on the tooling pallet 300 due to interaction force between the motor shell 600 and the rotor assembly, and the stability of the motor shell 600 in the process of putting the rotor assembly into the box can be ensured, and the influence on the accuracy of the position of the rotor assembly in the process of putting the rotor assembly into the box due to shaking is avoided.
