Description

Technical Field

[0001] This application relates to the field of brush holder processing, and in particular to a brush holder assembly and riveting fixture and riveting method. Background Technology

[0002] The brush holder is a key component of a generator, serving as an important device for securing the carbon brushes. The brush holder consists of a base plate and a brush box. The brush box is installed on the brush holder by riveting. Each brush box requires one solid rivet and one hollow rivet for installation. The brush box holds the carbon brushes, while the hollow rivet allows the lead wires to pass through. Typically, during brush holder assembly, the brush box is placed on the base plate, and the pins are passed through both the brush box and the base plate. Then, the brush box and base plate are inverted, and the brush box is manually riveted to the base plate, thus completing the brush holder assembly.

[0003] The aforementioned technologies have the following drawbacks: manual riveting is time-consuming and labor-intensive, and the brush box and pins are prone to falling off during manual riveting, affecting the assembly of the brush holder. Summary of the Invention

[0004] To address the issues of time-consuming and labor-intensive manual riveting, and the tendency for brush holders and pins to fall off during manual riveting, this application provides a brush holder assembly riveting fixture and riveting method.

[0005] The technical solution for a brush holder assembly and riveting fixture provided in this application is as follows:

[0006] A brush holder assembly and riveting fixture includes a support plate and a movable plate. The movable plate is located above the support plate, and the movable plate and the support plate slide relative to each other. The support plate is provided with a support seat for placing the brush holder base plate. A riveting column is installed on the support seat. The support seat is provided with a positioning component and a control component. The positioning component is used to fix the brush holder base plate relatively on the support seat, and the control component is used to fix the brush box and the brush holder base plate relatively. The movable plate is provided with a movable seat, and the movable seat is provided with a movable column.

[0007] By adopting the above technical solution, when the brush box and brush holder base plate need to be riveted, the operator moves the brush holder base plate to the support seat, and the positioning component fixes the brush holder base plate relatively on the support seat. The control component fixes the brush box and brush holder base plate relatively. Then, the moving plate moves the moving seat, which in turn moves the moving column, causing the moving column to abut against the pin. With the cooperation of the riveting column, the pin is riveted. No manual riveting is required, which reduces the possibility of the brush box and pin falling off and facilitates the assembly of the brush holder.

[0008] Preferably, the positioning component includes a positioning pin and a support member. The positioning pin and the support member are fixedly connected. The end of the positioning pin away from the support member passes through a through hole in the brush holder base plate. The support member and the positioning pin slide relative to each other. The support member is used to support the brush holder base plate and applies a thrust to the brush holder base plate.

[0009] By adopting the above technical solution, when the brush holder base plate is placed on the support base, the positioning pin can limit the brush holder base plate, so that the brush holder base plate and the support base are positioned relative to each other, which facilitates the installation of the brush box onto the brush holder base plate; the support member can support the brush holder base plate, so that when the moving column applies pressure to the pin, the brush box and the brush holder base plate are pressed together, which improves the accuracy of the brush box installation.

[0010] Preferably, the support member includes a support ring and a connecting block, the support ring and the connecting block are fixedly connected, the support ring abuts against the brush holder base plate, the connecting block has a through hole for the positioning pin to pass through, the positioning pin is fitted with a support spring, one end of the support spring abuts against the support seat, and the other end abuts against the connecting block.

[0011] By adopting the above technical solution, when the brush holder base plate is placed on the support ring, the support spring applies a pushing force to the connecting block, thereby applying a pushing force to the support ring, which facilitates the support ring to apply a pushing force to the brush holder base plate, thus facilitating the clamping of the brush holder base plate and the brush box.

[0012] Preferably, the control assembly includes a control post and a mandrel. The control post is mounted on a support base and passes through a through hole in the brush holder base plate. A guide groove is provided on the control post for the mandrel to pass through. The mandrel slides within the guide groove, and one end of the mandrel passes through the brush box.

[0013] By adopting the above technical solution, when the brush box and brush holder base plate need to be riveted, the operator moves the brush box onto the brush holder base plate, moves the pin so that the pin passes through the brush box and the brush holder base plate, moves the mandrel so that the mandrel passes through the brush box, and moves the brush holder base plate onto the control column. The control column can further limit the position of the brush holder base plate, and the mandrel is embedded in the guide groove. The guide groove can limit the position of the mandrel, and the mandrel can limit the position of the brush box, so that the brush box is relatively positioned on the brush holder base plate. When the pin is riveted, the brush box is prone to deformation. The mandrel can support the brush box and reduce the possibility of deformation.

[0014] Preferably, the support plate is provided with a limiting post, and the limiting post abuts against the movable plate.

[0015] By adopting the above technical solution, when the operator moves the moving plate and causes the moving column to rivet the pin, the limiting column can limit the moving distance of the moving plate to prevent the moving plate from moving too far and the moving column from damaging the pin. When the moving plate and the limiting column come into contact, the pin is riveted.

[0016] Preferably, the support plate is provided with a guide post, the movable plate and the guide post are slidably connected, the movable plate is provided with a through hole for the guide post to pass through, and a guide spring is sleeved on the guide post, one end of the guide spring abuts against the support plate and the other end abuts against the movable plate.

[0017] By adopting the above technical solution, when the moving plate moves toward the support plate, the guide column can limit the movement of the moving plate, reducing the possibility of deviation when the moving plate moves. The guide spring can apply a pushing force to the moving plate, so that the moving plate moves away from the support plate under normal circumstances, making it easier for the operator to place the brushing machine base plate on the support seat.

[0018] Preferably, the control assembly includes a positioning post, a first control rod, a second control rod, and a third control rod. The positioning post is mounted on a support base and passes through a through hole in the brush holder base plate. One end of the first control rod passes through the brush box and abuts against the positioning post. The first and second control rods are slidably connected, and the second and third control rods are slidably connected. The third control rod is mounted on the support plate.

[0019] By adopting the above technical solution, when the brush holder base plate and brush box are placed on the support plate, the positioning post can further position the brush holder base plate, and the operator can move the first control rod so that the first control rod passes through the brush box and abuts against the positioning post. The first positioning post can limit the brush box, so that the brush box is relatively positioned on the brush holder base plate, and the first control rod can support the brush box, reducing the possibility of deformation of the brush box. The second control rod can limit the sliding direction of the first control rod, and the third control rod can limit the sliding direction of the second control rod.

[0020] Preferably, the second control rod has a sliding groove for one end of the first control rod to be inserted into. A first auxiliary spring is provided at the bottom of the sliding groove, with one end fixedly connected to the bottom of the groove and the other end fixedly connected to the first control rod. A first positioning block is fixedly connected to the end of the first control rod inserted into the sliding groove. The end of the first positioning block away from the first control rod is a wedge surface. A second positioning block is rotatably connected to the bottom of the sliding groove. The end of the second positioning block facing the first control rod is a wedge surface. A torsion spring is mounted on the rotation shaft of the second positioning block. A limit block is fixedly connected to the bottom of the sliding groove. The second positioning block and the limit block abut against each other. The first positioning block and the second positioning block abut against each other. An auxiliary component is provided inside the second control rod to control the rotation of the second positioning block.

[0021] By adopting the above technical solution, when the operator moves the first control lever, the first control lever slides within the sliding groove. The sliding of the first control lever can drive the sliding of the first positioning block, causing the first positioning block and the second positioning block to abut against each other. The second positioning block rotates under the contact of the first positioning block and rotates under the action of the torsion spring, limiting the first positioning block and thus limiting the first control lever, so that the end of the first control lever away from the second control lever is inside the brush box. When the rivet pin applies pressure to the pin, the brush holder base plate moves under the pressure of the rivet pin, and the second positioning block rotates through the auxiliary component, releasing the second positioning block from limiting the first positioning block. The first control lever moves away from the second control lever under the action of the first auxiliary spring, thus moving the end of the first control lever away from the second control lever out of the brush box. At this time, the brush box and the brush holder base plate are installed. The operator can then remove the installed brush holder and install another set of brush boxes and brush holder base plates.

[0022] Preferably, the third control rod has an embedding groove for one end of the second control rod to be embedded in. A second auxiliary spring is provided at the bottom of the embedding groove. One end of the second auxiliary spring is fixedly connected to the bottom of the embedding groove, and the other end is fixedly connected to the second control rod. The auxiliary assembly includes an auxiliary rod, a first auxiliary block, and a second auxiliary block. The second control rod has an auxiliary groove that communicates with both the sliding groove and the embedding groove. One end of the auxiliary rod is hinged to the second positioning block, and the other end is hinged to the first auxiliary block. The first auxiliary block slides within the auxiliary groove. The second auxiliary block is fixedly connected to the bottom of the embedding groove, and the first and second auxiliary blocks abut against each other.

[0023] By adopting the above technical solution, when the first control rod slides into the sliding groove and the second positioning block limits the first positioning block, the first control rod moves under the pressure of the brush holder base plate, causing the second control rod to move. The movement of the second control rod can drive the movement of the auxiliary rod, and the movement of the auxiliary rod can drive the movement of the first auxiliary block, causing the first auxiliary block and the second auxiliary block to abut against each other. The second auxiliary block can apply a pushing force to the first auxiliary block, the first auxiliary block can apply a pushing force to the auxiliary rod, and the auxiliary rod can apply a pushing force to the second positioning block, releasing the limitation of the second positioning block on the first positioning block. This facilitates the first control rod to move away from the second control rod under the action of the first auxiliary spring, and facilitates the end of the first control rod away from the second control rod to move out of the brush box.

[0024] This application also provides a method for riveting and assembling a brush holder, including the following steps:

[0025] Move the brush box onto the base plate of the brush holder and pass one end of the rivet through the brush box and the base plate of the brush holder;

[0026] Move the mandrel so that it passes through the brush box;

[0027] The brush holder base plate is moved so that it is fitted onto the control column and the mandrel is embedded in the guide groove;

[0028] Control the movement of the movable plate to cause the movable plate to drive the movable column to move;

[0029] The moving column drives the brush box base plate to move downwards, and the riveting column abuts against the pin to achieve riveting.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. With the support base, positioning components, and control components, when the brush box and brush holder base plate need to be riveted, the operator moves the brush holder base plate onto the support base, and the positioning components fix the brush holder base plate relatively on the support base. The control components fix the brush box and brush holder base plate relatively. Then, the moving plate moves the moving base, which in turn moves the moving column, causing the moving column to abut against the pin. With the cooperation of the riveting column, the pin is riveted. No manual riveting is required, which reduces the possibility of the brush box and pin falling off and facilitates the assembly of the brush holder.

[0032] 2. By setting up the control column and mandrel, when the brush box and brush holder base plate need to be riveted, the operator moves the brush box onto the brush holder base plate and moves the pin so that the pin passes through the brush box and brush holder base plate. The mandrel is then moved so that it passes through the brush box, and the brush holder base plate is moved onto the control column. The control column can further limit the position of the brush holder base plate, and the mandrel is embedded in the guide groove. The guide groove can limit the position of the mandrel, and the mandrel can limit the position of the brush box, so that the brush box is relatively positioned on the brush holder base plate. When the pin is riveted, the brush box is prone to deformation. The mandrel can support the brush box and reduce the possibility of deformation. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0041] Example 1:

[0042] This application discloses a brush holder assembly and riveting fixture, such as... Figure 1 and 2 As shown, the assembly includes a support plate 1 and a movable plate 2. The movable plate 2 is located above the support plate 1 and moves towards the support plate 1. A support base 11 is bolted to the support plate 1, providing a place for the brush holder base plate 6. A rivet post 12 is fixedly mounted on the support base 11. A movable base 21 is bolted to the movable plate 2, and a movable post 22 is fixedly mounted on the movable base 21. The support base 11 is provided with a positioning component 3 and a control component 4. The positioning component 3 is used to fix the brush holder base plate 6 relatively on the support base 11, and the control component 4 is used to fix the brush box 61 and the brush holder base plate 6 relatively.

[0043] When the brush box 61 and the brush holder base plate 6 need to be riveted, the operator moves the brush holder base plate 6 onto the support seat 11, and fixes the brush holder base plate 6 on the support seat 11 by the positioning component 3. The control component 4 fixes the brush box 61 and the brush holder base plate 6 relative to each other. Then, the press applies a pushing force to the moving plate 2, causing the moving plate 2 to drive the moving seat 21 to move. The moving seat 21 drives the moving column 22 to move. The moving column 22 applies pressure to the pin 62, and with the cooperation of the riveting column 12, the pin 62 is riveted, thus realizing the installation of the brush box 61 and the brush holder base plate 6.

[0044] like Figure 1 As shown, a guide post 14 is fixedly connected to the support plate 1, and a movable plate 2 is slidably connected to the guide post 14. A through hole is provided on the movable plate 2 for the guide post 14 to pass through. A guide spring 15 is fitted onto the guide post 14, with one end abutting against the support plate 1 and the other end abutting against the movable plate 2. Under normal conditions, the guide spring 15 applies a pushing force to the movable plate 2, causing it to move away from the support plate 1. A limiting post 13 is fixedly connected to the support plate 1, with its length direction aligned with that of the guide post 14. The movable plate 2 can move until it abuts against the end of the limiting post 13 away from the support plate 1. When the operator moves the movable plate 2 using a press, the guide post 14 guides the movement of the movable plate 2, improving its stability. The limiting post limits the movement distance of the movable plate 2, facilitating the movement of the movable plate 2 and the moving post 22, thus facilitating the riveting work of the brush box 61 and the brush holder base plate 6.

[0045] like Figure 3As shown, the positioning component 3 includes a positioning pin 31 and a support member 32. The positioning pin 31 is fixedly connected to the support base 11. There are two positioning pins 31. The end of the positioning pin 31 away from the support base 11 passes through a through hole on the brush holder base plate 6. The two positioning pins 31 can limit the position of the brush holder base plate 6. The support member 32 and the positioning pin 31 slide relative to each other. The support member 32 can apply a pushing force to the brush holder base plate 6. The support member 32 includes a support ring 321 and a connecting block 322. The support ring 321 is for placing the brush holder base plate 6. The support ring 321 and the connecting block 322 are fixedly connected. There are two connecting blocks 322. The connecting blocks 322 are located on both sides of the support ring 321. The connecting blocks 322 have through holes for the positioning pins 31 to pass through. A support spring 311 is fitted onto the positioning pin 31. One end of the support spring 311 abuts against the support base 11, and the other end abuts against the connecting block 322. Under normal circumstances, the support spring 311 applies a pushing force to the connecting block 322, causing the connecting block 322 to move away from the support base 11. When the brush holder base plate 6 and the brush box 61 are placed on the support ring 321, and the moving column 22 applies a pushing force to the pin 62, the support spring 311 can apply a pushing force to the connecting block 322, thereby applying a pushing force to the support ring 321. The support ring 321 can apply a pushing force to the brush holder base plate 6, thereby making the brush holder base plate 6 and the brush box 61 close together, reducing the possibility of gaps between the brush box 61 and the brush holder base plate 6, and facilitating the installation of the brush box 61 and the brush holder base plate 6.

[0046] like Figure 3 As shown, the control assembly 4 includes a control post 41 and a mandrel 42. The control post 41 is fixedly mounted on the support base 11, and one end of the control post 41 passes through the support ring 321. When the brush holder base plate 6 is placed on the support ring 321, the control post 41 passes through the through hole on the brush holder base plate 6, and the control post 41 can further limit the position of the brush holder base plate 6. The mandrel 42 can pass through the brush box 61. The control post 41 has a guide groove 411 for the mandrel 42 to pass through, and the mandrel 42 slides within the guide groove 411. When it is necessary to install the brush box 61 onto the brush holder base plate 6, the operator moves the brush box 61 onto the brush holder base plate 6, moves the pin 62 through the brush box 61 and the brush holder base plate 6, then passes the mandrel 42 through the two brush boxes 61, moves the brush holder base plate 6 onto the support base 11, and the control post 41 passes through the through hole on the brush holder base plate 6. At this time, the mandrel 42 is embedded in the guide groove 411, which can limit the mandrel 42, thereby limiting the brush box 61, so that the brush box 61 is relatively positioned on the brush holder base plate 6; and when the pin 62 is riveted, the brush box 61 has deformed, and the mandrel 42 can support the brush box 61, avoiding the possibility of the brush box 61 moving when the pin 62 is riveted.

[0047] This application also discloses a brush holder assembly and riveting method, including the following steps:

[0048] Move the brush box 61 onto the brush holder base plate 6, and pass one end of the rivet through the brush box 61 and the brush holder base plate 6;

[0049] Move the mandrel 42 so that it passes through the brush box 61;

[0050] The brush holder base plate 6 is moved so that it is fitted onto the control column 41 and the core rod 42 is embedded in the guide groove 411.

[0051] Control the movement of the movable plate 2 so that the movable plate 2 drives the movable column 22 to move;

[0052] The moving column 22 drives the bottom plate of the brush box 61 to move downward, and the riveting column 12 abuts against the pin 62 to achieve riveting.

[0053] The implementation principle of the brush holder assembly riveting fixture and riveting method in this application embodiment is as follows:

[0054] When the brush box 61 and the brush holder base plate 6 need to be riveted, the operator moves the brush box 61 onto the brush holder base plate 6, moves the pin 62 so that the pin 62 passes through the brush box 61 and the brush holder base plate 6, moves the mandrel 42 so that the mandrel 42 passes through the brush box 61, and moves the brush holder base plate 6 onto the support ring 321, with the positioning pin 31 and the control pin 41 both passing through the through holes on the brush holder base plate 6. At this time, the mandrel 42 is embedded in the guide groove 411, so that the brush holder base plate 6 is located on the support ring 321. The brush box 61 is fixed on the brush holder base plate 6. Then, the operator uses a press to move the moving plate 2, which in turn moves the moving column 22. The moving column 22 can move until it abuts against the pin 62. The brush holder base plate 6 is pressed down under the action of the moving column 22, so that the riveting column 12 and the pin 62 protrude from one end of the brush holder base plate 6 and abut against each other, thereby riveting the pin 62 and realizing the riveting installation of the brush box 61 and the brush holder base plate 6.

[0055] Example 2:

[0056] like Figure 4 , 5As shown in Figure 6, the difference between this embodiment and Embodiment 1 is that the control component 4 in this embodiment includes a positioning post 43, a first control rod 44, a second control rod 45, and a third control rod 46. The positioning post 43 is fixedly installed on the support base 11, with one end of the positioning post 43 passing through the support. The positioning post 43 is solid and passes through a through hole on the brush holder base plate 6, thus limiting the position of the brush holder base plate 6. There are two first control rods 44, which are mirror images of each other. Each first control rod 44 includes an embedded part 441 and a moving part 442. The embedded part 441 has an L-shaped cross-section, and the moving part 442 has a U-shaped cross-section. The embedded part 441 and the moving part 442 are fixedly connected. The end of the embedded part 441 away from the moving part 442 passes through the brush box 61, and the end of the embedded part 441 passing through the brush box 61 can slide to abut against the positioning post 43. The moving part 442 is slidably connected to the second control rod 45. The second control rod 45 has a sliding groove 451 for inserting one end of the moving part 442 away from the inserting part 441. The sliding groove 451 limits the sliding direction of the moving part 442. The second control rod 45 has an L-shaped cross-section and is slidably connected to the third control rod 46. The third control rod 46 has an inserting groove 461 for inserting one end of the second control rod 45. The inserting groove 461 limits the sliding direction of the second control rod 45. The third control rod 46 is fixedly mounted on the support plate 1. The length direction of the third control rod 46 is vertical, and the length direction of the inserting groove 461 is consistent with the length direction of the third control rod 46. After the brush box 61 and the brush holder base plate 6 are placed on the support base 11, the operator can move the first control lever 44 so that the end of the first control lever 44 away from the second control lever 45 passes through the brush box 61 and abuts against the positioning post 43. The first control lever 44 can limit and support the brush box 61, reducing the possibility of deformation of the brush box 61.

[0057] like Figure 5 and 6As shown, a first auxiliary spring 452 is provided at the bottom of the sliding groove 451. One end of the first auxiliary spring 452 is fixedly connected to the bottom of the sliding groove 451, and the other end is fixedly connected to the end of the moving part 442 away from the embedded part 441. Under normal circumstances, the first auxiliary spring 452 applies a pushing force to the moving part 442, causing the moving part 442 to move away from the second control lever 45. A first positioning block 4421 is fixedly connected to the end of the moving part 442 embedded in the sliding groove 451. The cross-section of the first positioning block 4421 is L-shaped, and the end of the first positioning block 4421 away from the moving part 442 is set as a wedge surface. A second positioning block 453 is rotatably connected to the bottom of the sliding groove 451. The cross-section of the second positioning block 453 is L-shaped, and one end of the second positioning block 453 facing the moving part 442 is set as a wedge surface. A torsion spring is installed on the rotation shaft of the second positioning block 453. A limit block 455 is fixedly connected to the bottom of the sliding groove 451 and below the second positioning block 453. The torsion spring on the rotation shaft of the second positioning block 453 allows the second positioning block 453 to rotate toward the limit block 455. The second positioning block 453 and the limit block 455 abut against each other, and the limit block 455 can limit the rotation angle of the second positioning block 453, facilitating the abutment and cooperation between the second positioning block 453 and the first positioning block 4421. The first positioning block 4421 can move to abut against the second positioning block 453. After the first positioning block 4421 abuts against the second positioning block 453, the second positioning block 453 rotates under the action of the torsion spring, thereby limiting the first positioning block 4421. When the operator moves the insert 441 so that one end of the insert 441 passes through the brush box 61 and abuts against the positioning post 43, the movement of the insert 441 can drive the movement of the moving part 442. The second positioning block 453 limits the first positioning block 4421, thereby limiting the insert 441 and making the insert 441 abut against the positioning post 43, so that the first control rod 44 can play the role of limiting and supporting the brush box 61.

[0058] like Figure 5 and 6As shown, a second auxiliary spring 462 is provided at the bottom of the embedding groove 461. One end of the second auxiliary spring 462 is fixedly connected to the bottom of the embedding groove 461, and the other end is fixedly connected to the second control rod 45. Under normal circumstances, the second auxiliary spring 462 applies a pushing force to the second control rod 45, causing the second control rod 45 to move away from the third control rod 46. An auxiliary component 5 is provided inside the second control rod 45. The auxiliary component 5 includes an auxiliary rod 51, a first auxiliary block 52, and a second auxiliary block 53. An auxiliary groove 454 is opened on the second control rod 45, and the auxiliary groove 454 communicates with both the embedding groove 461 and the second control rod 51. One end of the auxiliary rod 51 is hinged to the second positioning block 453, and the other end is hinged to the first auxiliary block 52. The first auxiliary block 52 slides within the auxiliary groove 454, and the second auxiliary block 53 is fixedly connected to the bottom of the embedding groove 461. The first auxiliary block 52 can slide to abut against the second auxiliary block 53. After the second positioning block 453 limits the first positioning, the operator can then perform riveting work. The press drives the moving plate 2 to move, causing the moving column 22 to abut against the pin 62, thus pressing down the brush holder base plate 6 and the brush box 61. The movement of the brush box 61 drives the movement of the insert 441, which in turn drives the movement of the moving part 442. The movement of the moving part 442 drives the movement of the second control lever 45, causing it to move towards the third control lever 46. The movement of the second control lever 45 then drives the movement of the first auxiliary block 52. When the second auxiliary block 53 comes into contact with the first auxiliary block 52, the second auxiliary block 53 applies a pushing force to the first auxiliary block 52, and the first auxiliary block 52 applies a pushing force to the auxiliary rod 51, causing the auxiliary rod 51 to push the rotation of the second positioning block 453, thereby releasing the second positioning block 453 from limiting the first positioning block 4421. At this time, the moving part 442 moves away from the second control rod 45 under the action of the first auxiliary spring 452, thereby causing one end of the embedded part 441 to move out of the brush box 61. At this time, the operator can take out the riveted brush holder and move the brush holder base plate 6 to be riveted onto the support seat 11 to realize the riveting work of the pin 62.

[0059] The implementation principle of the brush holder assembly riveting fixture and riveting method in this application embodiment is as follows:

[0060] When the brush box 61 and the brush holder base plate 6 need to be riveted, the operator moves the brush box 61 onto the brush holder base plate 6, passes the pin 62 through the brush box 61 and the brush holder base plate 6, moves the brush holder base plate 6 onto the support ring 321, and the positioning pin 31 and the positioning post 43 pass through the through hole on the brush holder base plate 6. The operator moves the insert part 441 so that one end of the insert part 441 passes through the brush box 61 and abuts against the positioning post 43. The movement of the insert part 441 can drive the movement of the moving part 442, and the movement of the moving part 442 can drive the movement of the first positioning block 4421, so that the first positioning block 4421 and the second positioning block 453 abut against each other. The second positioning block 453 limits the first positioning block 4421 under the action of the torsion spring, thereby positioning the moving part 442. Then the operator rivets the brush box 61 and the brush holder base plate 6. The press moves the movable plate 2, which in turn drives the movable column 22 to abut against the pin 62. The embedded part 441 moves downward under the action of the brush box 61, thereby causing the second control rod 45 to move downward. The movement of the second control rod 45 can drive the movement of the first auxiliary block 52, causing the first auxiliary block 52 to move to abut against the second auxiliary block 53. The second auxiliary block 53 applies a pushing force to the first auxiliary block 52, causing the first auxiliary block 52 to apply a pushing force to the auxiliary rod 51. The auxiliary rod 51 can apply a pushing force to the second positioning block 453, causing the second positioning block 453 to rotate and release the limitation on the first positioning block 4421. Then, the movable part 442 moves away from the second control rod 45 under the action of the first auxiliary spring 452, thereby causing one end of the embedded part 441 to move out of the brush box 61. At this time, the riveting of the brush box 61 and the brush holder base plate 6 is completed.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
