DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7The present invention provides a technical solution: a multi-station stator mounting seat, comprising an operating table 1, a transmission frame 2 and a storage frame 3 arranged at the top of the operating table 1, a slide slot is opened at the top of the operating table 1, the transmission frame 2 is movably clamped inside the slide slot, a plurality of positioning plates 21 are installed at the top of the transmission frame 2, the positioning plates 21 are used to support and limit the motor housing, a connecting plate 32 and a hollow shaft 33 are arranged at the bottom of the storage frame 3, the connecting plate 32 is installed at the top of the operating table 1, the hollow shaft 33 is fixedly connected to the top of the connecting plate 32, a movable rod is rotatably arranged inside the hollow shaft 33, and the storage frame 3 is clamped at the top of the movable rod;

[0032] A plurality of limit rods 4 are provided at the top of the storage rack 3. The limit rods 4 are used to cooperate with the storage rack 3 to assist in supporting and positioning the positioning inner wall. When the stator needs to be limited and pressed into the motor housing, the stator can be limited and supported with the help of the storage rack 3 and the limit rods 4. The operator can position it with the help of bolts. When installation is required, the positioning on the storage rack 3 can be flipped so that it can be vertically pressed into the motor housing. The operator can also install it and multiple stators can be fed and transmitted simultaneously, which can improve the overall processing efficiency.

[0033] like Figure 6 As shown, in order to ensure the stability of the motor housing during the installation process, a limiting disk 22 is installed on the top of the positioning plate 21, and a blocking ring 23 is provided on the top of the limiting disk 22. A card slot is provided inside the blocking ring 23, which can be used to clamp a support block made of elastic material. A plurality of telescopic rods are installed at the bottom of the blocking ring 23, and the telescopic rods are installed on the limiting disk 22. The blocking ring 23 is used for the bottom of the bottom motor housing for auxiliary support. A plurality of buffer pads 221 are installed on the surface of the limiting disk 22. The buffer pads 221 are made of rubber and can be pressed against the side wall of the motor housing with the help of the blocking ring 23. The height of the blocking ring 23 can be adjusted according to different models of motor housings, and a support block can be clamped on the inner wall of the blocking ring 23 to adapt to the situation where there is a depression on the motor housing.

[0034] like Figure 7 As shown, when the stator is pressed into the motor housing, there is a gap between the bottom and the stator, and the feed amount between the stators and the motor housing of different models is not easy to control. A limit tube 24 is installed inside the limit plate 22, and an air inlet groove is opened at the bottom of the limit tube 24, and the air inlet groove is connected to the external air pressure equipment. There are multiple fixed grooves inside the limit plate 22, and fixed tubes 27 are installed inside the fixed grooves. A transmission rod 271 is inserted inside the fixed tube 27. The fixed tube 27 is connected with the limit tube 24, and can drive the transmission rod 271 to move under the action of the external air pressure equipment. After the external air pressure equipment starts to operate, it can push the transmission rod 271 to move inside the fixed tube 27, thereby driving the movable shaft 25 to move;

[0035] A movable shaft 25 is installed at one end of the transmission rod 271, and a support shaft 26 is installed on the top of the movable shaft 25. The support shaft 26 is used to rest against the bottom of the motor housing. When the movable shaft 25 moves outward, the support shaft 26 can move, and the motor housing can slide to the top of the buffer pad 221 under the action of gravity, so that the internal stator and motor housing can be adaptively assembled under the action of gravity to reduce the internal gap.

[0036] like Figure 2 As shown, in order to limit and clamp the stator, a plurality of sliding grooves are provided on the side wall of the storage rack 3, and a transmission plate 34 is movably provided inside the sliding groove, and the transmission plate 34 is rotatably arranged inside the sliding groove;

[0037] A mounting frame 341 is clamped on one side of the transmission plate 34, and a plurality of movable plug rods are installed on the top of the mounting frame 341, and a lifting plate 35 is installed on the top of the movable plug rods. A docking plate 31 is installed on the top of the lifting plate 35, and a limiting plug rod 4 is installed on the top of the docking plate 31. The transmission plate 34 can be flipped inside the sliding groove, and can flip the stator that has been positioned and installed, and cooperate with the lifting plate 35 to vertically press the stator into the motor housing to reduce bumps during transmission.

[0038] like Figure 5 As shown, the stator needs to be assembled and installed with the help of bolts before flipping. A plurality of arc grooves are provided on the docking plate 31, and the positions of the arc grooves correspond to the threaded holes on the stator. A plurality of limit plugs 36 are inserted on the side wall of the docking plate 31. Positioning holes are provided on the surface of the limit plugs 36 for correcting the position of the bolts. One end of the bolt can be stuck in the positioning hole, which can play a role in assisting feeding and preventing the bolt from being located at the bottom and being offset due to operator errors during the feeding process. The stator can be vertically installed on the top of the docking plate 31.

[0039] like Figure 5 As shown, since it is necessary to manually clamp the bolts to install the stator during the installation process, the efficiency is low. A receiving ring 37 is installed at the bottom of the limiting plug plate 36. The position of the receiving ring 37 corresponds to the positioning hole. A plurality of straight grooves are opened on the side wall of the receiving ring 37, and a clamping plate 38 is inserted inside the straight groove. A reset shaft 371 is installed at one end of the clamping plate 38. The reset shaft 371 is clamped on the outer wall of the receiving ring 37. A blocking shaft 381 is installed at the bottom of the clamping plate 38. The blocking shaft 381 is used to abut against the bottom of the receiving ring 37. Bolts of corresponding sizes can be clamped inside the receiving ring 37 according to the installed stator model, which is convenient for operators to install and disassemble. The bolts clamped inside the receiving ring 37 can be limited by means of the clamping plate 38 and the blocking shaft 381, which is convenient for subsequent installation and feeding, thereby ensuring the stability of the installation.

[0040] like Figure 3As shown, during the limiting process of the stator, manual positioning is prone to deviation. The limiting rod 4 is assembled from a fixed shaft and a movable sleeve. A plurality of vertical rods are installed on the top of the limiting rod 4, and a welding plate 41 is installed on the top of the vertical rod. A movable groove is opened on the welding plate 41, and a movable wheel 42 is rotatably arranged inside the movable groove. A transmission belt 421 is rotatably arranged on the movable wheel 42, and the transmission belt 421 passes through the movable sleeve and is clamped at the top of the fixed shaft.

[0041] A plurality of transmission shafts 43 are inserted inside the welding plate 41. A tooth groove is provided at the bottom of one end of the transmission shaft 43 inserted inside the welding plate 41. Gear rings are installed at both ends of the movable wheel 42, and the gear rings are meshed with the tooth grooves. The movable wheel 42 can drive the transmission shaft 43 to move. During the positioning process, the stator can be placed on the top of the docking plate 31. During the positioning process, the limiting rod 4 can be moved. Under the action of the transmission belt 421, the movable wheel 42 and the gears on both sides thereof can be driven to move, so that the transmission shaft 43 extends outward and can be against the inner wall of the stator, which is used to assist in supporting the positioning and reduce the displacement during the limiting process.

[0042] like Figure 3 As shown, in order to reduce the defective rate, an arc groove is opened at one end of the transmission shaft 43, and a buffer plate 44 is clamped inside the arc groove. The buffer plate 44 is used to abut against the inner wall of the stator. The buffer plate 44 can abut against the rubber of the wire inside the stator, while maintaining stability, it can also reduce damage to the internal components of the stator.

[0043] Working principle: First, when the stator needs to be limited and pressed into the motor housing, the stator can be limited and supported with the help of the storage rack 3 and the limit plug rod 4, and the operator can use the bolts to position it. When installation is required, the positioning on the storage rack 3 can be turned over to make it vertically pressed into the motor housing, and the operator can install it, and multiple stators can be fed and transmitted at the same time, which can improve the overall processing efficiency. In the positioning process, the stator can be placed on the top of the docking plate 31, and the limit plug can be used in the positioning process. The rod 4 moves, and can drive the movable wheel 42 and the gears on both sides thereof to move under the action of the transmission belt 421, so that the transmission shaft 43 extends outward and can be against the inner wall of the stator, which is used for auxiliary support positioning, and reduces the deviation during the limiting process. The position of the limiting plug plate 36 can be adjusted according to the stator frames of different sizes, so that the position of the limiting hole and the bolt hole corresponds to each other, and the bolt shaft inside the receiving ring 37 can be clamped inside the bolt hole to play a positioning role. The stator can be installed on the top of the docking plate 31, which is convenient for subsequent flipping installation;

[0044] Then, during the installation of the stator, the top of the bolt can be against the top of the blocking shaft 381, and the bolt of the corresponding size can be clamped inside the receiving ring 37, which is convenient for positioning and installation limiting in the subsequent assembly process, and is used to prepare for pressing it into the motor housing later, which can improve the overall processing efficiency. After the stator is turned over, the stator can be pressed into the motor housing, and the bolt can be removed. The top of the disassembled bolt can be clamped between the clamping plates 38, which can play a limiting role, preventing it from being stuck in the bolt hole of the stator during the separation process, and reducing the accidental tilt and deviation of the stator under the action of external force during the separation process;

[0045] Finally, when the external air pressure equipment starts to operate, the transmission rod 271 can be pushed to move, the support shaft 26 against the bottom of the motor housing can be retracted, the motor housing can fall onto the buffer pad 221 under the action of gravity, and the internal rotor can be inserted into the bottom of the motor housing to prevent the situation where there is a gap with the bottom during the pressing process. The operator can use bolts and other parts to connect the rotor and the motor housing to complete the assembly between the stator and the motor housing.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
