Description

Technical Field

[0001] The invention relates to the technical field of motor assembly, and in particular to an assembly tool and an assembly method for a high-profile motor stator subassembly. Background Art

[0002] The car seat high-profile motor is an important part of the car seat adjustment system. It adjusts the height and angle of the seat by controlling the rotation of the motor to provide passengers with a more comfortable and personalized riding experience. The high-profile motor usually has the characteristics of small size, light weight, high efficiency, smooth operation and low noise to meet the needs of car seat adjustment.

[0003] Among them, the stator subassembly is an important component of the high-profile motor, which is mainly composed of a stator housing, bearings, magnetic tiles, etc. When assembling the stator subassembly of the high-profile motor, the part that requires the highest assembly precision and the highest assembly difficulty is the assembly process of the magnetic tiles. This process is to transfer the two magnetic tiles into the housing separately, and fix the magnetic tiles to the designated positions on the inner wall of the housing in turn by means of adhesive bonding. The spacing between the two ends of the two magnetic tiles needs to be the same to ensure the uniformity and stability of the magnetic field.

[0004] However, the current magnetic tile assembly process still has the following problems: since the outer shell itself is usually made of metal material, during the assembly of the magnetic tiles, the magnetism of the magnetic tiles themselves will interfere with the placement process of the magnetic tiles, and then the problem of the magnetic tiles deviating from the specified position may occur; secondly, during the placement process, the two magnetic tiles have mutual magnetic forces due to their own magnetism, which will affect the accuracy of the magnetic tile placement position and the magnetic tile pasting process, which may easily cause the high-profile motor to be unable to be used or be damaged during use.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] like Figure 1-Figure 3 As shown, a high-profile motor stator subassembly assembly tool comprises: a base 1, a fixing frame 2 is fixedly provided on the upper end surface of the base 1, a sliding frame 3 is slidably provided on the upper end surface of the base 1 and is located on the right side of the fixing frame 2, the sliding frame 3 is driven by an external hydraulic cylinder (not shown in the figure) to move left and right, a fixing unit 4 for fixing the outer shell is provided on the fixing frame 2, the fixing unit 4 comprises a clamping plate 40, four circumferentially distributed clamping plates 40 are slidably provided on the right end surface of the fixing frame 2, a transverse plate 5 is fixedly provided on the left end surface of the sliding frame 3, and a fixing unit 2 6 for fixing the magnetic tile is provided on the transverse plate 5.

[0031] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the fixed unit 2 6 includes a rectangular block 60, and the left end face of the transverse plate 5 is fixedly provided with a rectangular block 60, and a group of plate groups are provided on the upper and lower sides of the rectangular block 60, and the plate group includes an opening plate 600 and a docking plate 601 distributed up and down and both are arc-shaped, and the two opening plates 600 are located between the two docking plates 601, and the right end face of the opening plate 600 is fixedly provided with two front-to-back symmetrical pushing blocks 602.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, a docking mechanism 7 is arranged between the fixed frame 2 and the sliding frame 3, and the docking mechanism 7 includes a driving unit 70 for driving the fixed unit 1 4 and the fixed unit 2 6 to operate, and a docking unit 71, and the docking unit 71 includes a guide cylinder 710, and the guide cylinder 710 is fixedly arranged on the right end face of the fixed frame 2, and a movable plate 711 is fixedly arranged on the left end face of the rectangular block 60 through a spring telescopic rod 1 with an axis horizontal, and a guide column 712 is fixedly arranged on the left end face of the movable plate 711.

[0033] During operation, the staff first places the shell to be assembled on the fixing unit 1 4 (at this time, the areas on the inner wall of the shell where the magnetic tiles need to be assembled are all coated with adhesive), and two magnetic tiles are placed on the fixing unit 2 6. Then the external hydraulic cylinder works to move the sliding frame 3 to the left. During the movement of the sliding frame 3 to the left, the driving unit 70 is operated. The driving unit 70 enables the four clamping plates 40 in the fixing unit 1 4 to clamp the shell, and the opening plate 600 and the docking plate 601 in the fixing unit 2 6 cooperate with each other to clamp the corresponding magnetic tiles. Secondly, during the continuous leftward movement of the sliding frame 3, the sliding frame 3 drives the spring telescopic rod 1. The movable plate 711 and the guide column 712 are moved to the left and inserted into the guide cylinder 710, so that the left shell and the right magnetic tile are initially aligned. Then, as the sliding frame 3 continues to move, the magnetic tile moves into the shell. In this process, the upper and lower docking plates 601 move until they contact the shell and then stop moving. The opening plate 600 pushes the magnetic tile into the shell through the pushing block 602 thereon and presses the magnetic tile to the specified inner wall area of ​​the shell. After a period of waiting for the magnetic tile to be adhered to the inner wall of the shell, the external hydraulic cylinder works to move the sliding frame 3 to the right and reset, and all parts are reset. Finally, the shell assembled in this step is taken out.

[0034] like Figure 1 and Figure 2As shown, the fixing unit 1 4 also includes a connecting block 41, and four connecting blocks 41 are slidably penetrated on the fixing frame 2, and the four connecting blocks 41 are circumferentially distributed about the guide cylinder 710, and the connecting blocks 41 are fixedly connected to the corresponding clamping plates 40, and a rotating shaft 410 coaxial with the guide cylinder 710 is rotatably provided on the left end surface of the fixing frame 2, and a rotating disk 411 is sleeved on the rotating shaft 410, and a traction bar 412 is rotatably provided between the rotating disk 411 and the connecting block 41.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the driving unit 70 includes a vertical shaft 700, and the upper end surface of the base 1 is rotatably provided with a vertical shaft 700 located on the left side of the fixed frame 2. Bevel gears 701 are fixedly provided on the vertical shaft 700 and the rotating shaft 410, and the two bevel gears 701 are meshed with each other. A gear 702 is fixedly sleeved on the lower end of the vertical shaft 700, and a transverse rod 703 is installed on the sliding frame 3 to slide left and right, and a rack 704 that slides through the fixed frame 2 is fixedly provided on the left end surface of the transverse rod 703, and the rack 704 is meshed with the gear 702, and a spring 705 sleeved on the transverse rod 703 is fixedly provided between the rack 704 and the sliding frame 3.

[0036] During operation, in the process of placing the shell, the staff places the shell between the four clamping plates 40, and allows the guide cylinder 710 to pass through the axial hole on the shell to provide preliminary support for the shell. Then, the external hydraulic cylinder works to move the sliding frame 3 to the left, and the sliding frame 3 drives the transverse rod 703 to continue to move to the left and compress the spring 1 705. The elastic force generated by the compression of the spring 1 705 causes the rack 1 704 to move to the left. The meshing between the rack 1 704 and the gear 1 702 causes the gear 1 702 to drive the vertical shaft 700 and the corresponding bevel gear 701 to rotate synchronously. The meshing makes the bevel gear 701 drive the rotating shaft 410 to rotate, and the rotating shaft 410 drives the rotating disk 411 and the traction bar 412 thereon to rotate synchronously, and the traction bar 412 pulls the corresponding connecting block 41 and the clamping plate 40 to move synchronously, so the four clamping plates 40 approach each other and contact the shell. As the sliding frame 3 continues to move, the spring 1 705 is continuously compressed, and the elastic force generated by the compression deformation of the spring 1 705 indirectly clamps the four clamping plates 40 to press the shell, completing the external clamping and fixing operation of the shell, and making the axis of the shell colinear with the axis of the guide cylinder 710, providing a reference for the subsequent assembly of the magnetic tile.

[0037] Secondly, during the process of the above-mentioned sliding frame 3 moving to the left, the sliding frame 3 drives the transverse plate 5, the rectangular block 60 and the guide column 712 to move synchronously, so the guide column 712 moves and is inserted into the guide tube 710. Therefore, the fixed frame 2, the rectangular block 60, the transverse plate 5, the guide column 712, the guide tube 710, the sliding frame 3 and the base 1 together form a stable frame, which prepares for the subsequent mobile assembly process of the magnetic tile, improves the stability of the subsequent outer shell and magnetic tile assembly, and then improves the accuracy of the tooling.

[0038] like Figure 1 , Figure 3 and Figure 6 As shown, the fixed unit 2 6 also includes a vertical column 61, and the upper and lower end surfaces of the rectangular block 60 are slidably penetrated by two vertical columns 61 distributed front and back, and the vertical columns 61 on the upper and lower end surfaces are staggered left and right, and the two vertical columns 61 located at the same end are away from the end surface of the rectangular block 60 and are fixedly connected to the corresponding support plate 600, and a sliding block 610 is slidably penetrated on the transverse plate 5, and a spring 2 611 is fixedly arranged between the sliding block 610 and the transverse plate 5, and the upper and lower end surfaces of the sliding block 610 are fixedly arranged with vertical plates 612, and the docking plate 601 is arranged on the left side of the vertical plate 612.

[0039] like Figure 1 , Figure 4 and Figure 6 As shown, the driving unit 70 also includes a U-shaped frame 706, and the U-shaped frames 706 are fixedly arranged on the opposite surfaces of the two support plates 600, and the openings of the two U-shaped frames 706 are back to back, and a bidirectional threaded rod 707 with a vertical axis is rotatably installed on the rectangular block 60, and the bidirectional threaded rod 707 is threadedly matched with the two U-shaped frames 706, and a gear 2 708 is fixedly sleeved on the bidirectional threaded rod 707, and a rack 2 709 meshing with the gear 2 708 is fixedly arranged on the movable plate 711 through a spring telescopic rod 2 with a horizontal axis.

[0040] like Figure 1 and Figure 3 As shown, a docking block 72 is fixedly provided on the outer arc surface of the docking plate 601, and a docking hole is penetrated through the docking block 72. The outer arc surfaces of the upper and lower clamping plates 40 are fixedly provided with guide rods 720 with horizontal axes and matched with the docking holes through the fixing blocks.

[0041] During operation, the staff places the magnetic tile between the support plate 600 and the corresponding docking plate 601 to complete the placement of the magnetic tile. At this time, the support plate 600 and the docking plate 601 cooperate with each other to support and initially restrict the magnetic tile, so as to facilitate the subsequent clamping and docking tooling operations. After that, after the sliding frame 3 drives the guide column 712 to insert into the guide cylinder 710 and the four clamping plates 40 complete the clamping operation of the shell, the sliding frame 3 continues to move left, and the sliding frame 3 drives the rectangular block 60 and the gear 2 708 thereon to move left synchronously, and the gear 2 708 and the rack 2 709 begin to mesh, and the meshing between the gear 2 708 and the rack 2 709 makes the gear The second 708 drives the bidirectional threaded rod 707 to rotate, and the threaded cooperation between the bidirectional threaded rod 707 and the two U-shaped frames 706 enables the U-shaped frames 706 to drive the corresponding expansion plates 600 to move synchronously. The two expansion plates 600 move away from each other, so the expansion plates 600 press the corresponding magnetic tiles against the corresponding docking plates 601, completing the clamping and fixing operation of the two magnetic tiles. Secondly, after the expansion plates 600 complete the expansion and clamping operation, as the sliding frame 3 continues to move, the gear second 708 and the rack second 709 move to the left synchronously, so that the spring telescopic rod second is continuously compressed, and the expansion plates 600 and the docking plates 601 maintain the clamping and fixing of the magnetic tiles.

[0042] As the sliding frame 3 continues to move, the docking block 72 on the docking plate 601 moves to the left, and the guide rod 720 is inserted into the docking hole on the corresponding docking block 72. Therefore, the upper and lower clamping plates 40 and the two docking plates 601 are formed together to form a stable rectangular frame through the above method, thereby improving the stability during the assembly process. Secondly, the guide rod 720 is inserted into the docking hole to guide the leftward movement of the magnetic tile again, thereby improving the accuracy during the assembly process.

[0043] As the rectangular block 60 continues to move, the docking block 72 on the docking plate 601 moves to be in close contact with the right end of the shell, and the sliding frame 3 continues to move. The rectangular block 60 continues to push the two magnetic tiles to the left through the support plate 600 and the push block 602. The docking plate 601 stops moving left and causes the spring 2 611 to be compressed. Finally, the push block 602 pushes the magnetic tiles to move left into the shell. During this process, the support plate 600 cooperates with the shell (the shell replaces the clamping function of the docking plate 601) to still keep the magnetic tiles clamped and fixed, and the support plate 600 presses the magnetic tiles against the inner wall of the shell, keeping the magnetic tiles clamped and fixed while allowing the magnetic tiles to fully contact with the adhesive, thereby ensuring the subsequent bonding effect of the magnetic tiles.

[0044] like Figure 1 , Figure 3 and Figure 6 As shown, mounting plates 73 are fixedly provided on both front and rear end surfaces of the transverse displacement plate 5, and an arc-shaped guide block 730 is provided on the left end surface of the mounting plate 73. The left portion of the guide block 730 is an isosceles trapezoidal section with the small end facing left, and the right portion is a straight section.

[0045] After the two magnetic tiles are installed in the outer shell, as the sliding frame 3 continues to move, the sliding frame 3 drives the guide block 730 to move left synchronously through the mounting plate 73, and the inclined surfaces of the left parts of the two guide blocks 730 squeeze the two magnetic tiles, so that the two magnetic tiles are finally in close contact with the straight section of the guide block 730, and the two guide blocks 730 make the distance between the two ends of the two magnetic tiles the same.

[0046] like Figure 5 As shown, the vertical plate 612 is slidably installed with a moving block 74, and the moving block 74 penetrates the vertical plate 612 left and right, the left end face of the moving block 74 is fixedly connected to the corresponding docking plate 601 through a connecting rod, and the right end face of the moving block 74 is slidably provided with a transverse block 740 left and right through a fixed rod, a spring three 741 is fixedly provided between the transverse block 740 and the moving block 74, a locking column 742 is fixedly provided on the left end face of the transverse block 740, and a plurality of locking grooves 743 equidistantly arranged from top to bottom are provided on the right end face of the vertical plate 612, and the locking columns 742 are plugged into and matched with the locking grooves 743 at corresponding positions.

[0047] like Figure 3 As shown, the mounting plate 73 is provided with a plurality of through holes which are arranged equidistantly from front to back, and plug-in posts 744 are inserted into the through holes, and the guide block 730 is fixedly disposed at the left end of the plug-in post 744 .

[0048] After the locking nut 742 is in the state of being tightened, the locking nut 743 is tightened and the locking nut 744 is tightened, so that the locking nut 743 is tightened and the locking nut 744 is tightened, so that the locking nut 743 is tightened and the locking nut 744 is tightened.

[0049] like Figure 1-Figure 6 As shown, in addition, the present invention also provides a method for assembling a high-profile motor stator subassembly, comprising the following steps: S1, placing the shell and magnetic tiles: the staff places the shell between four clamping plates 40, and passes the guide cylinder 710 through the axial hole on the shell to support the shell, and then places the magnetic tiles between the support plate 600 and the corresponding docking plate 601.

[0050] S2. Clamping the shell and magnetic tiles: the external hydraulic cylinder works to move the sliding frame 3 to the left, and the four clamping plates 40 are moved closer to each other and contact the shell through the driving unit 70. As the sliding frame 3 continues to move, the spring 1 705 is continuously compressed, so that the four clamping plates 40 clamp and press the shell, completing the external clamping and fixing operation of the shell, and making the axis of the shell and the axis of the guide cylinder 710 colinear. At the same time, during the movement of the sliding frame 3, the two support plates 600 are moved away from each other through the driving unit 70, so the support plates 600 press the corresponding magnetic tiles against the corresponding docking plates 601.

[0051] S3. Guide the moving magnetic tile: As the sliding frame 3 continues to move, the support plate 600 pushes the magnetic tile into the outer shell through the pushing block 602 thereon. During this process, the guide rod 720 is inserted into the docking hole on the corresponding docking block 72, so that the upper and lower clamping plates 40 and the two docking plates 601 together form a stable rectangular frame, which improves the stability during the assembly process. The leftward movement process of the magnetic tile is guided again by inserting the guide rod 720 into the docking hole, which improves the accuracy of the assembly process.

[0052] S4. Limit the placement of the magnetic tile: After the magnetic tile moves to the left and enters the shell, as the sliding frame 3 continues to move, the sliding frame 3 drives the guide block 730 to move to the left synchronously through the mounting plate 73. The inclined surfaces of the left parts of the two guide blocks 730 squeeze the two magnetic tiles, and finally the two magnetic tiles are in close contact with the straight section of the guide block 730. The two guide blocks 730 make the distance between the two ends of the two magnetic tiles the same. After the adhesive solidifies, the sliding frame 3 moves to the right to reset, and the assembled shell is taken out.
