Description

Technical Field

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

[0002] The motor stator is indeed a delicate and critical step in the production and assembly process. Due to the large size and complex structure of the stator, especially the upper and lower end surfaces are usually covered with exposed ends of copper wire coils, which makes it extremely difficult to press the stator only by manpower and easily cause damage. Therefore, modern manufacturing generally uses special press-fitting devices to complete this task.

[0003] However, the traditional press-fitting device also exposed some problems during operation. When the stator is pressed into the motor housing by the extrusion block, due to the irregular shape of the stator and the fragility of the copper wire winding coil, this direct physical pressure can easily cause the copper wire winding coil to deform, and may even cause the copper wire to crack, thereby damaging the stator and making it a defective product. This not only increases production costs, but also seriously affects the yield and quality of the motor.

[0004] Chinese patent publication number CN117155040B discloses a motor stator press-fitting device, including a base and a stand fixedly mounted on the top of the base, an assembly placement groove is opened on the upper end surface of the base, and a pressure cylinder is fixedly mounted on the top of the stand, a motor housing is placed inside the assembly placement groove, a stator is arranged on the upper part of the motor housing, and a press-fitting sleeve block capable of pressing the stator is also arranged, a plurality of copper wire windings are also arranged inside the stator, and a two-stage pressing assembly is arranged between the output end of the pressure cylinder and the press-fitting sleeve block.

[0005] When the stator abuts against the top of the motor casing and is ready to be pressed in, the stator needs to be placed accurately to ensure that the bottom end of the stator can be inserted into the motor casing. The stator pressing device abuts against the stator through the pressing sleeve and directly presses it into the motor casing. During this process, the stator and the motor casing are not positioned, which can easily lead to quality problems such as burrs on the inner hole of the motor casing, adhesion, and casing deformation when the stator is pressed into the motor casing. This will affect the overall structural strength of the motor and shorten the service life of the motor. Summary of the invention

[0006] In view of the above problems, a motor stator press-fitting device is provided. By clamping a positioning mechanism on a bracket, the clamping positioning mechanism can position the stator while clamping the motor casing to ensure the coaxiality of the motor casing and the stator, thereby solving the problem that the existing stator press-fitting device cannot ensure the coaxiality of the stator and the electronic casing, and direct press-fitting in a non-coaxial state will cause deformation of the motor casing.

[0014] Preferably, the positioning assembly includes a positioning member, a connecting rod, a hydraulic thruster, and a synchronous hydraulic regulator. The two connecting rods are parallel and one end is rotatably connected to one end of the mounting groove, the other ends of the two connecting rods are rotatably connected to the positioning member, and the two ends of the hydraulic thruster are respectively rotatably connected to one of the connecting rods and the inner side of the abutment member.

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides:

[0032] A motor stator 12 press-fitting device includes a bracket, a clamping table for placing a motor housing 11 is provided in the bracket, a press-fitting mechanism that can move downward is provided on the top of the clamping table, a clamping and positioning mechanism is provided on the clamping table, the clamping and positioning mechanism has abutments 41 distributed along the circumference of the clamping table, and a positioning assembly 42 that can synchronously move along the radial direction of the motor housing 11 is also provided on the top of the abutment 41. In the press-fitting state, all the abutments 41 are radially abutted against the outer circumferential surface of the motor housing 11 with a constant pressure, and all the positioning assemblies 42 are radially abutted against the outer circumferential surface of the stator 12 with a constant pressure.

[0033] The bracket includes an upper support plate 21, a lower support plate 22, and a column 23 arranged between the upper support plate 21 and the lower support plate 22. The top surface of the upper support plate 21 forms a clamping table surface. The pressing mechanism includes a movable plate 31 slidably arranged between the upper support plate 21 and the lower support plate 22. A connecting head 32 connected to the output shaft of the pressing machine is arranged at the top end of the movable plate 31, and a pressing cylinder 33 is arranged at the bottom end of the movable plate 31.

[0034] During operation, the motor housing 11 is placed on the clamping table, and the stator 12 is placed on the motor housing 11, so that the motor housing 11 and the stator 12 tend to be coaxial, and the clamping and positioning mechanism is started, so that all the abutting members 41 are radially abutted against the outer circumference of the motor housing 11 with a constant pressure, and all the positioning components 42 are radially abutted against the outer circumference of the stator 12 with a constant pressure, so that the motor housing 11 and the stator 12 can be coaxially positioned, and the press machine is started, so that its output shaft drives the movable plate 31 to move downward, so that the press cylinder 33 can coaxially abut against the top of the stator 12, and as the output shaft of the press machine descends, the stator 12 can be coaxially pressed into the motor housing 11. In this process, the stator 12 and the motor housing 11 are subjected to uniform force, which can effectively prevent the stator 12 and the motor housing 11 from being compressed and deformed due to uneven force.

[0035] This embodiment can not only stably clamp the motor housing 11 to prevent displacement during the press-fitting process by clamping and positioning the mechanism on the bracket, but also, more importantly, can accurately position the stator 12. By adjusting the position and angle of the clamping and positioning mechanism, it can ensure that the stator 12 and the motor housing 11 are on the same axis, thereby ensuring the coaxiality of the two, solving the problem that the traditional stator 12 press-fitting device cannot ensure the coaxiality of the stator 12 and the motor housing 11, thereby avoiding deformation of the motor housing 11 and damage to the internal structure due to different axes. Secondly, due to the stability and accuracy of the clamping and positioning mechanism, the accuracy and efficiency of the stator 12 press-fitting can be greatly improved, reducing production costs and scrap rates. In addition, this design also makes the entire press-fitting process safer and more reliable, reducing accidents caused by improper operation.

[0036] like Figure 4 and Figure 5 As shown, the clamping and positioning mechanism also includes a synchronous execution component arranged at the bottom of the clamping table, and a synchronous trigger component arranged on the press-fitting mechanism and capable of transmitting with the synchronous execution component. The synchronous execution component has a connecting portion that can move radially along the motor housing 11, and the connecting portion is connected to the abutment 41. When the synchronous trigger component transmits power to the synchronous execution component, the connecting portion drives the abutment 41 to radially abut against the outer circumferential surface of the motor housing 11.

[0037] The motor housing 11 and the stator 12 are placed on the clamping table, and the press-fitting mechanism is started so that the synchronous trigger assembly connected to the press-fitting mechanism can move downward until the synchronous trigger assembly and the synchronous execution assembly are transmitted. The connecting part of the synchronous execution assembly can drive the abutment 41 to radially abut against the outer circumferential surface of the motor housing 11. When the peripheral side of the motor housing 11 has a force distributed along its circumferential direction, the motor housing 11 is clamped and kept coaxial with the press-fitting cylinder 33, and the positioning assembly 42 is installed at the top of the abutment 41, so that the positioning assembly 42 clamps and positions the stator 12 at the top of the motor housing 11 at the same time, thereby meeting the requirements of precise press-fitting.

[0038] like Figure 5 As shown, the synchronous execution component includes a rotating disk 431 and a connecting bolt 432. The rotating disk 431 is rotatably set at the bottom of the clamping table, and the connecting bolt 432 is set on the clamping table to slide along the radial direction of the rotating ring. The rotating disk 431 is provided with a guide groove 4311 deviating from its radial direction, and the bottom end of the connecting bolt 432 passes through the clamping table and extends into the guide groove 4311.

[0039] When it is necessary to make all the abutment members 41 move synchronously along the radial direction of the pressing cylinder 33 to clamp and position the motor housing 11 therein, rotating the rotating disk 431 can change the intersection of the guide groove 4311 on the rotating disk 431 and the sliding trajectory of the connecting bolt 432, so that the connecting bolt 432 can move along the radial direction of the rotating disk 431, so that the abutment members 41 connected to the connecting bolt 432 can abut on the outer circumferential surface of the motor housing 11 along the radial direction of the rotating disk 431.

[0040] like Figure 5 As shown, the synchronous execution component also includes a driving cylinder 433 and a driving ring 434. The driving cylinder 433 is coaxially fixedly arranged on the circumferential surface of the rotating disk 431, and the driving ring 434 is coaxially slidably arranged on the outer circumferential surface of the driving cylinder 433. The outer circumferential surface of the driving cylinder 433 is provided with an arc groove 4331 coaxial therewith, and the inner circumferential surface of the driving ring 434 is provided with a guide bolt 4341 extending radially into the arc groove 4331. When the synchronous trigger assembly abuts against the top of the driving ring 434 and drives it to move from top to bottom, the driving cylinder 433 drives the rotating disk 431 to rotate.

[0041] When it is necessary to rotate the rotating disk 431, the driving ring 434 is moved from top to bottom, and the guide bolt 4341 on the inner side of the driving ring 434 extends into the arc groove 4331 and slides with it. When the guide bolt 4341 moves downward in the longitudinal direction, the guide groove 4311 can be deflected when there is a downward force on its bottom side, so that the driving cylinder 433 drives the rotating disk 431 to rotate a certain angle at the bottom of the clamping table, and the pressing mechanism can drive the synchronous trigger assembly to move downward, so that the synchronous trigger assembly can abut against the driving disk and drive the driving disk to move downward.

[0042] like Figure 5 As shown, the bracket further includes a positioning platform 24 disposed at the bottom of the driving ring 434 , and an elastic reset element 435 is disposed between the positioning platform 24 and the driving ring 434 .

[0043] A guide column 25 extending in the longitudinal direction is further provided between the bracket and the positioning platform 24 . The guide column 25 slides through the driving ring 434 , and the elastic reset element 435 is sleeved on the guide column 25 .

[0044] When the synchronous trigger assembly abuts against the driving ring 434 and drives it to move downward, it needs to overcome the elastic force of the elastic reset element 435, so that the synchronous trigger assembly moves upward and away from the driving ring 434. The driving ring 434 moves upward under the action of the elastic reset element 435, and at the same time, the driving cylinder 433 is reset under the action of the guide bolt 4341 in its arc groove 4331, so that the rotating disk 431 can drive the abutment 41 to reset, thereby facilitating continuous clamping and positioning.

[0045] like Figure 3 As shown, the synchronous trigger assembly includes a pressure column 441 that slides longitudinally through the press-fitting mechanism. The pressure column 441 is located at the bottom of the press-fitting mechanism and is provided with a step surface. An elastic compression element 442 is provided between the step surface and the press-fitting mechanism. An escape opening is provided on the clamping table for the pressure column 441 to pass through and abut against the drive ring 434.

[0046] A limit ring 443 is provided at the top of the pressing column 441 to prevent the pressing column 441 from sliding downward and separating from the pressing mechanism.

[0047] When the movable plate 31 moves downward, the pressure column 441 connected thereto can move downward until the bottom end of the pressure column 441 passes through the avoidance opening and abuts against the top end of the driving ring 434. Then, the movable plate 31 continues to move downward, and the elastic compression element 442 is reset, so that the pressure column 441 elastically abuts against the top end of the driving ring 434, thereby preventing the movable plate 31 from directly transmitting the downward rigid force to the driving ring 434, thereby effectively buffering the force.

[0048] like Figure 6 and Figure 7 As shown, the abutting member 41 has an abutting surface 411 extending along the tangential direction of the motor housing 11 , and a mounting groove 412 located at the top end of the abutting surface 411 and used for mounting the positioning assembly 42 .

[0049] The abutment surface 411 of the abutment member 41 can abut against the outer circumferential surface of the motor housing 11 in the radial direction, so that the force applied by the abutment member 41 to the motor housing 11 is more uniform, and by opening a mounting groove 412 at the top of the abutment member 41, the positioning assembly 42 can be installed in the mounting groove 412 to form a stable structure.

[0050] like Figure 8 , Fig. 9 and Fig.10 As shown, the positioning assembly 42 includes a positioning member 421, a connecting rod 422, a hydraulic thruster 423, and a synchronous hydraulic regulator 424. The two connecting rods 422 are parallel and one end is rotatably connected to one end of the mounting groove 412. The other ends of the two connecting rods 422 are rotatably connected to the positioning member 421. The two ends of the hydraulic thruster are respectively rotatably connected to one of the connecting rods 422 and the inner side of the abutment member 41. The synchronous hydraulic regulator 424 has the same number of hydraulic output ports 4241 as the hydraulic thrusters 423. The hydraulic output ports 4241 are connected to the hydraulic thrusters 423 through hoses.

[0051] A roller 425 is provided at one end of the positioning member 421 , and an inclined surface is provided at the top of the positioning member 421 . The stator 12 abuts against the inclined surface and is inserted between the positioning members 421 , and the roller 425 abuts against the outer circumferential surface of the stator 12 .

[0052] When the abutment 41 abuts against the outer circumferential surface of the motor housing 11 radially, the positioning members 421 installed on the top of the abutment 41 can abut against the outer circumferential surface of the stator 12, and make the roller 425 abut against the positioned outer circumferential surface, and the synchronous liquid regulator can input hydraulic pressure to the hydraulic pusher 423, so that the output shaft of the hydraulic pusher 423 can push the connecting rod 422, so that the positioning member 421 connected to the connecting rod 422 drives the roller 425 to abut against the positioned outer circumferential surface, so that the stator 12 can move downward in the positioned state, so that the stator 12 can be pressed into the motor housing 11.

[0053] like Fig.10 As shown, a piston 4231 is provided in the hydraulic pusher 423, and the piston 4231 divides the inner cavity of the hydraulic pusher 423 into a pressure chamber 4232 and a pressure relief chamber 4233. The pressure chamber 4232 is connected to the hydraulic output port 4241, and one end of the piston 4231 facing downward toward the pressure relief chamber 4233 is provided with a plug rod 4235 rotatably connected to the connecting rod 422.

[0054] A pressure relief hole 4234 communicating with the atmosphere is provided at the end of the pressure relief chamber 4233 .

[0055] When the roller 425 abuts against the outer circumference of the stator 12, the piston rod 4231 drives the piston 4231 to compress the pressure chamber 4232, and the pressure chamber 4232 is connected to the synchronous hydraulic regulator 424, so that when the pressure chamber 4232 is compressed, the pressure of the pressure chamber 4232 of all hydraulic pushers 423 is stabilized by the synchronous hydraulic regulator 424, thereby ensuring that all rollers 425 have the same force on the stator 12, thereby ensuring that the stator 12 can be positioned coaxially with the motor housing 11.

[0056] like Figure 3 and Fig. 9 As shown, the inner cavity of the synchronous hydraulic regulator 424 is provided with a plug disc 4242 , an elastic adjustment element 4243 and an adjustment disc 4244 in sequence from top to bottom, and the top of the plug disc 4242 forms an oil cavity connected to the hydraulic output port 4241 .

[0057] A coaxial threaded bolt 4245 is provided at the bottom end of the adjusting disk 4244, and the threaded bolt 4245 passes through the synchronous adjuster and is threadedly connected to it. By rotating the threaded bolt 4245, the height of the adjusting disk 4244 can be adjusted, thereby adjusting the elastic pressure at the bottom end of the plug disk 4242, thereby adjusting the pressure required for the plug disk 4242 to move downward.

[0058] The plug disc 4242 compresses the adjustment chamber on its top through the elastic adjustment element 4243. When the pressure chamber 4232 of the hydraulic pusher 423 transmits the hydraulic pressure to the adjustment chamber, the pressure of the elastic adjustment element 4243 needs to be overcome. Since all the pressure chambers 4232 are connected to the adjustment chamber, it is ensured that all the positioning members 421 drive the roller 425 to abut against the circumferential surface of the stator 12 with a constant pressure, thereby ensuring that the stator 12 can be coaxially positioned with the motor housing 11.

[0059] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
