[0002] The car alternator is the main power source for a car. Its function is to supply power to all electrical equipment (except the starter motor) and charge the battery while the engine is running normally.

[0003] In the production of alternators, brush installation fixtures are an important auxiliary tool used to ensure that brushes can be accurately and quickly installed into the generator. However, existing fixtures have some shortcomings, such as susceptibility to damage due to insufficient material toughness, complex structure leading to manufacturing difficulties, long manufacturing cycles, and long replacement times after damage. These issues seriously affect efficient and normal production. Summary of the Invention

[0004] This utility model provides a brush holder installation fixture that is beneficial to improving production efficiency.

[0005] The technical solution to the above problem is as follows:

[0006] A brush holder mounting fixture, comprising:

[0007] support;

[0008] A clamping mechanism for holding the brush holder assembly is connected to the bracket.

[0009] The lifting drive mechanism is connected to the bracket.

[0010] The first driver is connected to the lifting drive mechanism;

[0011] A toggle assembly is connected to the power output terminal of the first driver.

[0012] Furthermore, the clamping mechanism includes a clamping driver, a clamping arm, and a clamping block. The clamping driver is fixed to the bracket, one end of the clamping arm is fixed to the clamping driver, and the other end of the clamping arm is fixed to the clamping block.

[0013] Furthermore, the clamping arm includes a first connecting segment, a second connecting segment, and a third connecting segment. The two ends of the second connecting segment are fixed to the first connecting segment and the third connecting segment respectively, forming a first included angle between the second connecting segment and the first connecting segment, and forming a second included angle between the second connecting segment and the third connecting segment.

[0014] Furthermore, the lifting drive mechanism includes a lifting driver and a lifting mounting base. The lifting driver is fixed to the bracket, the lifting mounting base cooperates with the lifting driver, and the first driver is fixed to the lifting driver.

[0015] Furthermore, the actuating assembly includes a first actuating assembly and a second actuating assembly, wherein the first actuating assembly is fixed to the lifting drive mechanism and the second actuating assembly is fixed to the first driver.

[0016] Furthermore, both the first and second actuation components include a paddle mounting base and a paddle, with the paddle fixed to the paddle mounting base.

[0017] Furthermore, the second actuation assembly also includes a cover plate, and the actuation plate mounting base is provided with an assembly groove. The cover plate and the actuation plate are respectively engaged with the assembly groove, and the actuation plate is located between the cover plate and the mounting base.

[0018] Furthermore, the paddle is made of Cr12MoV cold work die steel.

[0019] Furthermore, it also includes a support plate and a positioning post. The support plate is fixed to the bracket, one end of the positioning post is fixed to the support plate, and the other end of the positioning post is provided with a pin for engaging with a hole on the brush holder assembly. There is a step between the pin and the positioning post.

[0020] The operation process of this utility model is as follows: The operator engages the brush holder assembly pre-installed with the brush with the pin, that is, the hole on the brush holder assembly mates with the pin, and the axial end face of the brush holder assembly abuts against the step between the pin and the positioning post, so that the brush holder assembly is axially positioned. At the same time, the brush forms a loose sleeve against the first actuating component, and the brush holder assembly is supported by the operator. Subsequently, the operator activates the clamping drive, which drives the clamping arm and clamping block to move, thereby clamping the brush holder assembly by the clamping block. The operator activates the lifting drive, which drives the lifting mounting base to descend. The first drive and the second actuating component descend with the lifting mounting base. During this process, the second actuating component is inserted into the inner hole on the brush. The operator activates the first drive, which drives the second actuating component to move. The second actuating component drives the brush to move, so that the brush and brush holder assembly engage in the predetermined direction. When the brush abuts against the first actuating component, the first drive stops working. At this time, the brush and brush holder assembly are in place.

[0028] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art are briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other embodiments can be obtained based on the drawings without creative effort, and these embodiments are still within the protection scope of the claims of this utility model.

[0029] like Figures 1 to 4 This utility model discloses a brush holder installation fixture, which includes a bracket 1, a clamping mechanism, a lifting drive mechanism, a first driver B, a toggle assembly, a support plate 9, and a positioning column 10. The following is a detailed description of each part and the relationship between them.

[0030] The bracket 1 includes a back plate 1a, a support arm 1b, a fixing plate 1c, and a support 1d. The support arm 1b is L-shaped and is fixed to the back plate 1a. The fixing plate 1c is fixed to both the back plate 1a and the support arm 1b. The support 1d is fixed to the fixing plate 1c.

[0031] The clamping mechanism is used to clamp the brush holder assembly A. The clamping mechanism is connected to the bracket 1. The clamping mechanism is fixed to the support 1d. The clamping mechanism includes a clamping driver 2, a clamping arm 3, and a clamping block 4. The clamping driver 2 is fixed to the bracket 1. The clamping driver 2 is located on the back of the back plate 1a and is fixed to the back plate 1a. When the lifting drive mechanism and the first driver B are working, the clamping driver 2 located on the back of the back plate 1a can avoid interference with the lifting drive mechanism and the first driver B. The clamping driver 2 preferably adopts a finger cylinder. One end of the clamping arm 3 is fixed to the clamping driver 2, and the other end of the clamping arm 3 is fixed to the clamping block 4.

[0032] The clamping arm 3 includes a first connecting section 3a, a second connecting section 3b, and a third connecting section 3c. The two ends of the second connecting section 3b are fixed to the first connecting section 3a and the third connecting section 3c, respectively. A first angle is formed between the second connecting section 3b and the first connecting section 3a, and a second angle is formed between the second connecting section 3b and the third connecting section 3c. Both the first angle and the second angle are 90°. After the clamping arm 3 adopts the above structure, a part of the clamping arm 3 extends to the front of the back plate 1a, so that the clamping mechanism, the lifting drive mechanism, and the first driver B are reasonably distributed.

[0033] The lifting drive mechanism is connected to the bracket 1, and the first driver B is connected to the lifting drive mechanism. The lifting drive mechanism includes a lifting driver 5 and a lifting mounting base 6. The lifting driver 5 is fixed to the bracket 1, and the lifting mounting base 6 cooperates with the lifting driver 5. The first driver B is fixed to the lifting driver 5. The lifting driver 5 is a linear driver, which can be a cylinder, hydraulic cylinder, electric linear module, or other linear driver. The lifting mounting base 6 consists of a vertical mounting plate 6a and a horizontal mounting plate 6b. The vertical mounting plate 6a and the horizontal mounting plate 6b are fixed, forming a 90° angle between them. The vertical mounting plate 6a is fixed to the lifting driver 5, and the first driver B is fixed to the horizontal mounting plate 6b.

[0034] The actuating assembly is connected to the power output terminal of the first driver. The actuating assembly includes a first actuating assembly and a second actuating assembly. The first actuating assembly is fixed to the lifting drive mechanism, and the second actuating assembly is fixed to the first driver. When the brush holder assembly A is engaged with the positioning post 10, the brush C forms an empty sleeve around the first actuating assembly. When the lifting drive mechanism descends, the second actuating assembly descends along with the lifting drive mechanism and inserts into the inner hole on the brush C.

[0035] Both the first and second toggle assemblies include a paddle mounting base 7a and a paddle 7, with the paddle 7 fixed to the paddle mounting base 7a. In the first toggle assembly, the paddle mounting base 7a is fixed to the support plate 9, and in the second toggle assembly, the paddle mounting base 7a is fixed to the first driver B.

[0036] The second actuating assembly also includes a cover plate 8, and a mounting slot is provided on the actuating plate mounting base 7a. The cover plate 8 and the actuating plate 7 respectively mate with the mounting slot, and the actuating plate 7 is located between the cover plate 8 and the mounting base 6. The actuating plate 7 is made of Cr12MoV cold work die steel. The actuating plate 7 made of this material has higher wear resistance and impact resistance, thereby improving the durability of the tooling during long-term use.

[0037] The lever 7 is in a straight line shape. This design reduces material usage while maintaining sufficient strength and rigidity. Furthermore, the use of two parts, the cover plate 8 and the lever mounting base 7a, reduces the number of repeated clamping operations during processing, as well as welding, drilling, and other steps, significantly reducing the cost, difficulty, and time required for spare parts manufacturing.

[0038] The cover plate 8, the lever 7, and the lever mounting base 7a are integrated by screw fastening. The three components are installed by overlapping screw fastening. This design allows for quick replacement in a limited space, reducing the time required for tooling changes and thus reducing production losses.

[0039] The support plate 9 is fixed to the bracket 1. One end of the positioning post 10 is fixed to the support plate 9, and the other end of the positioning post 10 is provided with a pin 11 for engaging with a hole on the brush holder assembly A. There is a step between the pin 11 and the positioning post 10. The support plate 9 is provided with a clearance notch 9a, which engages with the first driver B.

[0040] The working process of this utility model is as follows:

[0041] The operator engages the brush holder assembly A, pre-installed with brush C, with the pin 11. Specifically, the hole on brush holder assembly A mates with pin 11, and the axial end face of brush holder assembly A abuts against the step between pin 11 and positioning post 10, thus axially positioning brush holder assembly A. Simultaneously, brush C forms a loose sleeve around the first actuating component. At this point, the operator applies support force to brush holder assembly A. Subsequently, the operator activates clamping actuator 2, which moves clamping arm 3 and clamping block 4, causing clamping block 4 to clamp brush holder assembly A. The operator then activates lifting actuator 5, which lowers lifting mounting base 6. The first actuator B and the second actuating component descend with lifting mounting base 6. During this process, the second actuating component inserts into the inner hole on brush C. The operator starts the first drive B, which drives the second actuating component to move. The second actuating component moves the brush C, causing the brush C to engage with the brush holder assembly A in a predetermined direction. When the brush C comes into contact with the first actuating component, the first drive B stops working. At this time, the brush C and the brush holder assembly A are in place, and this engagement can be detected by the distance sensor.
