Description

Technical Field

[0001] The invention relates to the technical field of motor assembly, and in particular to a motor assembly device. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It is mainly composed of a stator, a rotor, a casing and end covers. The stator and rotor of the motor are its two core components. The stator contains winding coils for generating a magnetic field, while the rotor carries permanent magnets or electromagnetic coils, which rotate under the action of the magnetic field generated by the stator, thereby realizing the function of the motor.

[0003] When assembling the stator and rotor into the motor housing, the housing is usually positioned on a work surface first, and then the stator is placed into the housing. During the placement process, it is necessary to ensure that the windings on the stator will not be squeezed or damaged. The rotor is then inserted into the stator and connected to the housing, and then the end cover is installed on the housing. However, when assembling the motor, the stator and rotor need to be assembled in two steps, which increases the steps of motor assembly and reduces the efficiency of motor assembly. In addition, the stator and rotor are usually clamped and limited in a suspended manner during the assembly process. The stator and rotor have low stability during the assembly process and are prone to collision with the motor housing, causing wear or damage to the motor, thereby reducing the quality of the assembled motor.

[0035] See also Figure 1 and Figure 2 The motor assembly device also includes an assembly unit 4, which is arranged at the front side of the upper end of the base plate 1. The assembly unit 4 includes a hydraulic push rod 41 installed at the upper end of the base plate 1. A U-shaped frame 42 slidably connected to the base plate 1 is installed at the front end of the hydraulic push rod 41, and a rotating component 43 is commonly connected to the two vertical sections of the U-shaped frame 42.

[0036] See also Figure 1 and Figure 2The rotating component 43 includes two rotating rods 431 which are symmetrically distributed on the left and right and are respectively rotatably connected to the two vertical sections of the U-shaped frame 42. The opposite ends of the two rotating rods 431 are plugged with T-shaped rods 432. Two baffle plates 433 which are symmetrically distributed up and down are arranged on the front and rear sides of the T-shaped rod 432. The baffle plates 433 are fixedly connected to the vertical sections of the U-shaped frame 42. An I-shaped plate 434 is installed between the two rotating rods 431.

[0037] During specific operation, the base plate 1 is initially fixed in the working position, the hydraulic push rod 41 is connected to the existing hydraulic pump, the two T-bars 432 and the two rotating rods 431 are in a separated state before assembly, the I-plate 434 is rotated to make the middle section of the I-plate 434 in a horizontal state, and then the two T-bars 432 are respectively inserted into the two rotating rods 431, and the longitudinal sections of the T-bars 432 are respectively inserted between the corresponding four baffle plates 433, and the four baffle plates 433 limit the T-bar 432 to prevent the rotating rod 431 from rotating, thereby further realizing the function of limiting the I-plate 434.

[0038] See also Figure 1 , Figure 2 , Figure 6 and Figure 8 The rotating component 43 is connected to a plurality of evenly distributed clamping components 44, and a distance adjusting component 45 is connected to the clamping component 44. The clamping component 44 includes a cylindrical tube 441 connected to the rotating component 43. The middle section of the I-plate 434 is fixedly connected to the plurality of cylindrical tubes 441. A plurality of circumferentially evenly distributed limiting components 442 are connected to the tube wall of the cylindrical tube 441. An adjusting component 443 is connected to the outer surface of the cylindrical tube 441, and a clamping component 444 is connected to the adjusting component 443.

[0039] See also Figure 1 , Figure 6 and Figure 8 The adjusting assembly 443 includes a threaded sleeve 4431 threadedly connected to the outer surface of the cylindrical tube 441, and a circular plate 4432 is installed on the outer surface of the threaded sleeve 4431. The circular plate 4432 is provided with a plurality of arc-shaped waist holes 4433 evenly distributed in the circumferential direction.

[0040] See also Figure 2 , Figure 6 and Figure 8The clamping assembly 444 includes a connecting ring 4441 installed at the end of the cylindrical tube 441, and a plurality of circumferentially evenly distributed positioning frames 4442 are installed on the outer surface of the connecting ring 4441. A sliding through hole 4443 is opened on the frame wall of the positioning frame 4442 close to the annular plate 4432. A rectangular sliding bar 4444 is slidably connected in the positioning frame 4442. A clamping bar 4445 is installed at one end of the rectangular sliding bar 4444 away from the annular plate 4432.

One end of the cylindrical rod 4446 is fixedly connected to the rectangular sliding bar 4444, and the other end of the cylindrical rod 4446 slides through the arc-shaped waist hole 4433.

[0041] During specific operation, before assembly, the I-plate 434 drives the cylindrical tube 441 to be in a vertical state, and the threaded sleeve 4431 is rotated according to the diameter of the stator to be assembled. The threaded sleeve 4431 drives the annular plate 4432 to rotate, and the annular plate 4432 pushes the multiple cylindrical rods 4446 through the hole walls of the multiple arc-shaped waist holes 4433. The multiple cylindrical rods 4446 slide in the corresponding sliding through holes 4443 and drive the corresponding rectangular sliding bars 4444 to slide in the corresponding positioning frames 4442. The rectangular sliding bars 4444 drive the clamping bars 4445 to move, thereby changing the clamping range of the multiple clamping bars 4445 to match the diameter of the stator. Subsequently, the multiple stators are placed between the corresponding multiple clamping bars 4445, and the multiple clamping bars 4445 clamp and limit the multiple stators (such as Fig. 9 shown).

[0042] See also Figure 1 , Figure 2 , Figure 6 , Figure 8 and Fig. 9 The distance adjusting component 45 includes a plurality of moving rods 451 evenly distributed in the circumference and slidably connected to the end of the cylindrical tube 441, and a sliding component 452 is commonly connected to the plurality of moving rods 451, and a distance adjusting component 453 is connected to the sliding component 452, and a moving component 454 is also connected to the sliding component 452.

[0043] See also Figure 2 , Figure 8 and Fig. 9 The sliding assembly 452 includes a cylindrical frame 4521 fixedly connected to the plurality of moving rods 451 , and a circular plate 4522 is installed at one end of the cylindrical frame 4521 away from the cylindrical tube 441 .

[0044] See also Figure 1 , Figure 2 , Figure 6 and Figure 8The limiting component 442 includes a sliding plate 4421 that slides through and is connected to the wall of the cylindrical tube 441, a clamping arc plate 4422 is installed at one end of the sliding plate 4421 close to the axis of the cylindrical tube 441, an inclined surface is provided at one end of the sliding plate 4421 away from the axis of the cylindrical tube 441, a strip plate is integrally formed at one end of the sliding plate 4421 away from the axis of the cylindrical tube 441, a connecting spring 4423 is installed between the strip plate and the outer surface of the cylindrical tube 441, guide plates 4424 are provided on both sides of the sliding plate 4421, and the guide plates 4424 are fixedly connected to the outer surface of the cylindrical tube 441.

[0045] See also Figure 1 , Figure 2 , Figure 6 and Figure 8 The moving assembly 454 includes a rotating ring 4543 rotatably connected to the end of the circular plate 4522 away from the cylindrical frame 4521, and a plurality of traction rods 4541 uniformly distributed in the circumference are arranged on the outer periphery of the rotating ring 4543. The traction rod 4541 is slidably connected with the circular plate 4522, and a plurality of uniformly distributed arc through holes 4542 are opened on the traction rod 4541. A plurality of circumferentially uniformly distributed clamping rods 4544 are installed on the outer ring surface of the rotating ring 4543, and the clamping rod 4544 is an L-shaped structure. The clamping rod 4544 is plugged into the corresponding arc through hole 4542, and the traction rod 4541 is located between the corresponding two guide plates 4424. The traction rod 4541 is located at one end of the two guide plates 4424 and is integrally formed with a right-angled triangle protrusion.

[0046] During specific operation, initially, the rotating ring 4543 drives the multiple clamping rods 4544 and the corresponding arc-shaped through holes 4542 to be in a separated state. According to the axial length of the rotor to be assembled, the cylindrical frame 4521 is slid, and the cylindrical frame 4521 moves along the axis of the cylindrical tube 441 through the moving rod 451. At the same time, the cylindrical frame 4521 drives the circular plate 4522 to move, and the circular plate 4522 slides on the multiple traction rods 4541. When the cylindrical frame 4521 moves to the desired position, the rotating ring 4543 is rotated, and the rotating ring 4543 drives the multiple clamping rods 4544 to be plugged and matched with the corresponding arc-shaped through holes 4542, thereby realizing the function of connecting the circular plate 4522 with the traction rod 4541, and then limiting the cylindrical frame 4521.

[0047] After the cylindrical frame 4521 is adjusted, the rotor is inserted into the positioned stator, and the rotor is in a vertical state when connected to the stator. The rotor moves downward due to its own gravity, and the rotor's rotating shaft gradually enters the cylindrical tube 441 and pushes the pitch adjustment component 453. The pitch adjustment component 453 is forced to drive the cylindrical frame 4521 to move, and the cylindrical frame 4521 drives multiple traction rods 4541 to move through the circular plate 4522. The right-angled triangle protrusions on the multiple traction rods 4541 push the corresponding inclined surfaces on the sliding plate 4421. The sliding plate 4421 is forced to drive the clamping arc plate 4422 to move in the direction of the rotor's rotating shaft and clamp it to limit the position, thereby realizing the automatic clamping and limiting function of the rotor. There is no need to clamp the rotor inserted in the stator, which reduces the steps of the assembly process. At the same time, the sliding plate 4421 compresses the connecting spring 4423.

[0048] See also Figure 1 , Figure 2 , Figure 5 and Figure 7 The motor assembly device also includes a placement unit 3, which is provided with multiple and evenly connected to the upper end of the support platform 2. The placement unit 3 includes two rectangular plates 31 symmetrically installed on the upper end of the support platform 2, and a clamping component 32 is connected to the rectangular plate 31. Two blocking rods 33 symmetrically distributed on the left and right are provided at the rear side between the two rectangular plates 31, and the lower end of the blocking rod 33 is fixedly connected to the upper end of the support platform 2.

[0049] See also Figure 1 and Figure 7 The clamping component 32 includes a limit plate 322 that is slidably connected to the rectangular plate 31 and is in a vertical state. A clamping spring 323 that is sleeved on the outer periphery of the rectangular rod 321 is installed between the limit plate 322 and the rectangular plate 31.

[0050] During specific operation, multiple motor casings are placed in multiple placement units 3 in turn. During the placement process, the motor casings first contact and squeeze the corresponding two limit plates 322. The limit plates 322 are subjected to force to slide through the rectangular rods 321 and squeeze the clamping springs 323. When the motor casing is placed in the desired position, the squeezed clamping springs 323 clamp and limit the motor casing through the limit plates 322.

[0051] See also Figure 1 and Figure 6 The upper end of the horizontal section of the U-shaped frame 42 is connected to a plurality of evenly distributed support components 46, and the support component 46 includes a support rod 461 with an L-shaped structure and installed at the upper end of the horizontal section of the U-shaped frame 42, and an arc plate 462 is installed at the upper end of the vertical section of the support rod 461.

[0052] During specific operation, when the motor housing is limited, the two T-shaped rods 432 are pulled out, and then the I-shaped plate 434 is slowly rotated. The I-shaped plate 434 drives multiple cylindrical tubes 441 to rotate toward the motor housing to a horizontal state. The cylindrical tubes 441 drive the stator and the rotor to move to a horizontal state through multiple clamping rods 4544. At this time, the lower end of the annular plate 4432 is tightly attached to the inner arc surface of the arc plate 462. The arc plate 462 limits the annular plate 4432 through the support rod 461 to ensure that the stator and rotor in the horizontal state are in a stable state. Then the hydraulic push rod 41 is started, and the hydraulic push rod 41 drives the U-shaped The frame 42 moves toward the direction of multiple motor housings, and the U-shaped frame 42 drives the multiple cylindrical tubes 441 to move through the I-shaped plate 434. The cylindrical tubes 441 drive the stator and the rotor to move toward the motor housing. The stator and the rotor gradually enter the corresponding motor housing at the same time. There is no need to assemble the stator and the rotor into the motor housing in sequence in two steps, thereby effectively improving the efficiency of motor assembly and effectively reducing the number of collisions between the stator and the rotor and the motor housing, ensuring the integrity of the motor. After the stator and the rotor enter the motor housing, the stator and the rotor are fixed in the motor housing by existing bolts.

[0053] See also Figure 1 , Figure 2 , Figure 6 and Fig. 9 The distance adjustment component 453 includes an adjusting screw 4531 threadedly connected to the circular side wall of the cylindrical frame 4521, the adjusting screw 4531 is threadedly connected to the circular plate 4522, and a positioning plate 4532 is installed at one end of the adjusting screw 4531 close to the cylindrical tube 441.

[0054] During specific operation, the positioning plate 4532 is tightly attached to the end of the rotor shaft during the motor assembly process. After the stator and the rotor are fixed in the motor housing, the adjusting screw 4531 is rotated, and the adjusting screw 4531 drives the positioning plate 4532 to move away from the rotor shaft. The connecting spring 4423 in the compressed state drives the inclined surface on the sliding plate 4421 to push the traction rod 4541. The traction rod 4541 drives the cylindrical frame 4521 to move through the circular plate 4522, and the movement of the positioning plate 4532 Provide movable conditions for the cylindrical frame 4521, thereby ensuring that the sliding plate 4421 can move, and the sliding plate 4421 drives the clamping arc plate 4422 to separate from the rotating shaft of the rotor, releasing the clamping limit of the rotor, and then the hydraulic push rod 41 drives the U-shaped frame 42 to reset, and the U-shaped frame 42 drives the multiple cylindrical tubes 441 to reset through the I-plate 434, and then the assembled motor is taken out from between the multiple limit plates 322, and finally the motor cover is installed on the motor housing through existing technology, and the motor assembly is completed.

[0055] The overall working steps of the present invention are as follows: initially, according to the length of the rotating shaft of the rotor to be assembled, the cylindrical frame 4521 is slid, and the cylindrical frame 4521 drives the circular plate 4522 to slide on multiple traction rods 4541. When the cylindrical frame 4521 moves to the required position, the rotating ring 4543 is rotated, and the rotating ring 4543 drives multiple clamping rods 4544 to be plugged into and matched with the corresponding arc-shaped through holes 4542, so as to connect the circular plate 4522 with the traction rod 4541, thereby limiting the cylindrical frame 4521.

[0056] Before assembly, the I-plate 434 drives the cylindrical tube 441 to be in a vertical state, and the two T-bars 432 are respectively inserted into the two rotating rods 431. The longitudinal sections of the T-bars 432 are respectively inserted between the corresponding four baffle plates 433. The four baffle plates 433 limit the T-bars 432 to prevent the rotating rod 431 from rotating. Subsequently, the multiple stators are respectively placed in a vertical state between the corresponding multiple clamping bars 4445, and by rotating the threaded sleeve 4431, the multiple clamping bars 4445 are driven to clamp and limit the multiple stators.

[0057] Next, the rotor is vertically inserted into the positioned stator. The rotor in the vertical state moves downward due to its own gravity, so that the main part of the rotor is inserted into the stator, and the rotor shaft gradually enters the cylindrical tube 441 and pushes the positioning plate 4532. The positioning plate 4532 is forced to drive the cylindrical frame 4521 to move through the adjusting screw 4531. The cylindrical frame 4521 drives multiple traction rods 4541 to move through the circular plate 4522. The right-angled triangle protrusions on the traction rods 4541 push the corresponding inclined surfaces on the sliding plates 4421. The sliding plates 4421 are forced to drive the clamping arc plates 4422 to clamp and limit the rotor shaft.

[0058] Next, multiple motor casings are placed in multiple placement units 3 in turn. During the placement process, the motor casings first contact and squeeze the corresponding two limit plates 322. The limit plates 322 are subjected to force to slide through the rectangular rods 321 and squeeze the clamping springs 323. When the motor casing is placed in the desired position, the squeezed clamping springs 323 clamp and limit the motor casing through the limit plates 322.

[0059] When the motor housing is limited, the two T-shaped rods 432 are pulled out, and then the I-shaped plate 434 is slowly rotated. The I-shaped plate 434 drives the multiple cylindrical tubes 441 to rotate toward the motor housing to a horizontal state. The cylindrical tubes 441 drive the stator and the rotor to move to a horizontal state through multiple clamping rods 4544. At this time, the lower end of the annular plate 4432 is tightly attached to the inner arc surface of the arc plate 462. The arc plate 462 limits the annular plate 4432 through the support rod 461 to ensure that the stator and rotor in the horizontal state are in a stable state.

[0060] It should be noted that after the rotor is inserted into the stator, the rotor and the stator are in a locked state. When the rotor and the stator are rotated to a horizontal state, the two remain in the locked state. The stator supports the rotor and the rotor will not move downward. Therefore, the clamping arc plate 4422 will not be affected by the downward force and affect the clamping limit effect.

[0061] Then, the hydraulic push rod 41 is started, and the hydraulic push rod 41 drives the U-shaped frame 42 to move toward the motor housings. The U-shaped frame 42 drives the cylindrical tubes 441 to move through the I-plate 434. The cylindrical tubes 441 drive the stator and the rotor to move toward the motor housings. After the stator and the rotor enter the motor housing, the stator and the rotor are fixed in the motor housing by bolts.

[0062] After the stator and rotor are fixed in the motor housing, the adjusting screw 4531 is rotated, and the adjusting screw 4531 drives the positioning plate 4532 to move in the direction away from the rotor shaft. At this time, the cylindrical frame 4521 has space to move toward the cylindrical tube 441, and then the compressed connecting spring 4423 drives the inclined surface on the sliding plate 4421 to push the traction rod 4541, and the traction rod 4541 drives the cylindrical frame 4521 to move toward the cylindrical tube 441 through the circular plate 4522, and the sliding plate 4421 drives the clamping arc plate 4422 to separate from the rotor shaft, releasing the clamping limit on the rotor shaft, and then the hydraulic push rod 41 drives the U-shaped frame 42 to reset, and the U-shaped frame 42 drives multiple cylindrical tubes 441 to reset through the I-plate 434, and then the assembled motor is taken out from between the multiple limit plates 322, and finally the motor cover is installed on the motor housing, and the motor assembly is completed.
