[0048] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0049] The utility model relates to an anti-wear detection device for a brush holder assembly, such as Figures 1 to 5 As shown, including:

[0050] Mounting mechanism 1, independently fixed, provides stable support for the entire device;

[0051] An assembly 2 is provided on the mounting mechanism 1. A guide rail group 3 is provided on the assembly 2. The guide rail group 3 is composed of at least one parallel guide rail.

[0052] The moving member 4 is provided on the guide rail assembly 3 and is slidably installed along the length direction of the guide rail assembly 3;

[0053] The mounting shaft 5 is rotatably arranged in the connection hole of the moving part 4 through a bearing, allowing it to rotate freely. One end of the mounting shaft 5 is provided with an external thread, and a nut 6 is installed on the external thread;

[0054] The friction member 7 is coaxially arranged on the mounting shaft 5. The friction member 7 rotates synchronously with the mounting shaft 5. The friction member 7 is fixed to the mounting shaft 5 by a nut 6.

[0055] a driving mechanism 8 , provided on the assembly member 2 , for providing a rotational force to the friction member 7 ;

[0056] An adjustment mechanism 9 is provided on the assembly part 2 and is used to adjust the working position of the friction member 7;

[0057] A support mechanism 10 is provided on the mounting mechanism 1 and is used for clamping the brush holder assembly;

[0058] The working principle of this device is as follows:

[0059] The brush holder assembly to be tested is placed on the support mechanism 10 and fixed to ensure that the surface of the brush holder assembly is in good contact with the friction member 7. The adjustment mechanism 9 is started to adjust the position of the moving member 4 on the guide rail group 3 so that the contact surface of the friction member 7 and the brush holder assembly reaches the predetermined position. The driving mechanism 8 is started to drive the mounting shaft 5 and the friction member 7 to rotate. The brush holder assembly is tested through the friction member 7. The rotation speed and time of the driving mechanism 8 are set to simulate the wear conditions in actual use. The rotation of the friction member 7 is monitored to ensure the stability and accuracy of the testing process. After the test is completed, the driving mechanism 8 is turned off to stop the rotation of the friction member 7. The brush holder assembly is removed for subsequent analysis and evaluation.

[0060] Through the design of the driving mechanism 8 and the adjusting mechanism 9, efficient wear detection is achieved and the detection efficiency is improved. The design of the adjusting mechanism 9 allows the working position of the friction member 7 to be flexibly adjusted to meet different detection requirements.

[0061] The traditional drive mechanism can be realized by using existing technologies such as simple motor direct drive or gear transmission. However, these existing technologies can only realize a single rotation action and often lack sufficient transmission efficiency and stability. In this device, it is necessary to realize efficient, smooth and precise rotation of the friction member 7. At the same time, the transmission system is required to have sufficient strength and durability to adapt to long-term wear detection tasks and ensure the stability and accuracy of the detection process. In order to solve the above problems, this device designs a better drive mechanism 8, such as Figures 1 to 5 As shown, specifically including:

[0062] The hollow shaft 81 is rotatably disposed in the inner hole of the moving member 4, and the hollow shaft 81 is arranged parallel to the rotation axis of the mounting shaft 5;

[0063] Two pulleys 82 are coaxially arranged on the hollow shaft 81 and the mounting shaft 5, respectively, and the two pulleys 82 are connected by a transmission belt 83;

[0064] The isolation member 84 is provided on the moving member 4, and the transmission belt 83 is located in the inner cavity of the isolation member 84 to protect the transmission system from the influence of the external environment;

[0065] The power mechanism 85 is provided on the assembly 2 and is used to provide a rotational force to the hollow shaft 81;

[0066] The working principle of the driving mechanism 8 of this device is as follows:

[0067] Start the power mechanism 85, and drive the hollow shaft 81 to rotate through the servo motor. The hollow shaft 81 drives the installation shaft 5 and the friction member 7 to rotate through the transmission belt 83. After the detection is completed, turn off the power mechanism 85 and stop the rotation of the friction member 7.

[0068] Through the transmission method of the pulley 82 and the transmission belt 83, efficient power transmission is achieved, ensuring that the friction member 7 can rotate smoothly and accurately. The design of the isolation member 84 not only protects the transmission system from the influence of the external environment, but also reduces operational risks and improves the safety of the equipment.

[0069] The traditional power mechanism can be realized by using existing technologies such as simple motor direct drive or reduction gearbox transmission. However, these existing technologies can only realize basic rotation drive functions, and often have problems such as low transmission efficiency, high maintenance cost, and difficulty in adapting to complex working conditions. Since the present device needs to realize efficient, smooth and precise rotation of the friction member 7, and at the same time requires the power mechanism to have sufficient strength and durability to adapt to long-term wear detection tasks and ensure the stability and accuracy of the detection process, the traditional power mechanism can no longer meet the requirements. In order to solve the above problems, the present device designs a better power mechanism 85, such as Figures 1 to 5 As shown, specifically including:

[0070] The drive shaft 85a is rotatably mounted on the assembly 2, and the hollow shaft 81 is coaxially mounted with the drive shaft 85a. The hollow shaft 81 rotates synchronously with the drive shaft 85a, and the hollow shaft 81 is slidably mounted along the length direction of the drive shaft 85a.

[0071] The power motor 84b is provided on the assembly 2, and the output end of the power motor 84b is installed with the drive shaft 85a;

[0072] The working principle of the power mechanism 85 of this device is as follows:

[0073] The power motor 84b is started to drive the drive shaft 85a to rotate, and the drive shaft 85a drives the installation shaft 5 and the friction member 7 to rotate through the hollow shaft 81, the pulley 82 and the transmission belt 83;

[0074] Through the design of the drive shaft 95a and the power motor 84b, efficient power transmission is achieved, ensuring that the friction member 7 can rotate smoothly and accurately. The direct connection between the hollow shaft 81 and the drive shaft 95a reduces the intermediate links, improves the transmission efficiency, and reduces energy loss. At the same time, after the connection position of the hollow shaft 81 and the drive shaft 95a changes, the transmission relationship remains unchanged.

[0075] The traditional adjustment mechanism can be realized by existing technologies such as manual knobs, electric push rods or hydraulic cylinders. However, these existing technologies can only realize simple position adjustment functions, and often have problems such as low adjustment accuracy, inconvenient operation and difficulty in adapting to the needs of automated detection. Since the present device needs to realize accurate, fast and stable adjustment of the position of the friction member 7 relative to the brush holder assembly, and at the same time requires the adjustment mechanism to have sufficient rigidity and precision to adapt to long-term wear detection tasks and ensure the stability and accuracy of the detection process, the traditional adjustment mechanism can no longer meet the needs. In order to solve the above problems, the present device designs a better adjustment mechanism 9, such as Figures 1 to 3 As shown, specifically including:

[0076] The lead screw 91 is provided on the assembly 2 and is mounted in cooperation with the threaded through hole of the moving part 4 to ensure that the relative movement between the two is smooth and without shaking. The rotation axis of the lead screw 91 is arranged parallel to the trajectory of the moving part 4.

[0077] The drive motor 92 is provided on the assembly 2, and the output end of the drive motor 92 is coaxially mounted with the lead screw 91 to ensure direct and efficient power transmission;

[0078] The working principle of the regulating mechanism 9 of this device is as follows:

[0079] When the working position of the friction member 7 relative to the brush holder assembly needs to be adjusted, the drive motor 92 starts to rotate, driving the lead screw 91 to rotate synchronously. Since the lead screw 91 and the moving member 4 are connected by threads, as the lead screw 91 rotates, the moving member 4 will perform a linear reciprocating motion along the guide rail assembly 3, thereby changing the position of the friction member 7.

[0080] By using the drive motor 92 as the driving force source, very fine position adjustment can be achieved. The screw transmission method has good self-locking performance and can maintain the current position unchanged even when the power supply is cut off, thereby improving the safety of the system.

[0081] As a preferred solution, Figure 1 and Figure 2 As shown, the mounting mechanism 1 includes:

[0082] The base 11 can be made of high-strength cast iron material. A discharge port is provided in the middle of the rear side for discharging waste or debris generated during the inspection process. A guide groove 12 is provided at the discharge port to guide the waste to a designated location to avoid contaminating the work area. The assembly 2 is provided on the base 11 and is located on the side where the discharge port is provided.

[0083] The foot assembly 13 is provided on the base 11 and consists of a plurality of height-adjustable support feet for leveling the base 11;

[0084] The base 11 is made of heavy cast iron material, which ensures the stability of the entire device during operation and reduces measurement errors caused by vibration. The design of the discharge port and guide groove 12 makes it easier to clean up the waste generated during the inspection process and keeps the working environment clean. The foot group 13 provides a convenient and fast leveling mechanism, which can quickly adjust to the required working state even on uneven ground, thereby improving the applicability of the device.

[0085] The conventional support mechanism can be realized by using existing technologies such as a simple fixed platform or a manual adjustment device. However, these existing technologies can only realize simple support and limited adjustment functions, and often have problems such as low adjustment accuracy, inconvenient operation, and difficulty in adapting to brush holder assemblies of different sizes and shapes. Since the present device needs to realize efficient, accurate and stable support of the brush holder assembly, and at the same time requires the support mechanism to have sufficient rigidity and accuracy to adapt to long-term wear detection tasks and ensure the stability and accuracy of the detection process, the conventional support mechanism can no longer meet the requirements. In order to solve the above problems, the present device designs a better support mechanism 10, such as Figures 1 to 5 As shown, specifically including:

[0086] The movable platform 101 is slidably disposed on the base 11. The movable platform 101 carries the brush holder assembly to be inspected, and the moving track of the movable platform 101 is perpendicular to the moving track of the movable member 4.

[0087] Two conductive members 102 are symmetrically arranged at both ends of the movable platform 101, and the two conductive members 102 are respectively slidably arranged in the positioning holes at both ends of the base 11 to provide a guide for the movable platform 101 to ensure the straightness during the movement;

[0088] The threaded rod 103 is rotatably disposed at a positioning hole on one side of the base 11, and the threaded rod 103 is connected to the threaded inner hole of the conductive member 102 on the same side. The rotation of the threaded rod 103 can drive the conductive member 102 and the entire movable platform 101 to move along the guide rail;

[0089] The transmission motor 104 is provided on the base 11, and the output end of the transmission motor 104 is coaxially mounted with the threaded rod 103. The transmission motor 104 is used to adjust the distance between the friction member 7 and the brush holder assembly;

[0090] The control mechanism 105 is provided on the movable platform 101, and the control mechanism 105 and the movable platform 101 are provided with a clamping mechanism 106, which is used for positioning and clamping the brush holder assembly;

[0091] The control mechanism 105 includes:

[0092] The auxiliary member 105a is slidably disposed inside the positioning groove of the movable platform 101, and the moving track of the auxiliary member 105a is arranged parallel to the moving track of the friction member 7, for further fine-tuning the position of the brush holder assembly;

[0093] The threaded column 105b is rotatably mounted on the movable platform 101 and is engaged with the inner thread groove of the auxiliary member 105a. When the threaded column 105b rotates, the auxiliary member 105a moves along the positioning groove of the movable platform 101.

[0094] The conduction motor 105c is disposed on the movable platform 101, and the output end of the conduction motor 105c is coaxially mounted with the threaded column 105b, responsible for driving the threaded column 105b to rotate;

[0095] The clamping mechanism 106 includes:

[0096] Two fixing members 106a are respectively provided on the moving platform 101 and the auxiliary member 105a;

[0097] Two positioning chucks 106b are respectively provided on the two fixing members 106a, and the two positioning chucks 106b are located at adjacent ends of the two fixing members 106a. The two positioning chucks 106b are coaxially installed to clamp and fix the brush holder assembly to be tested;

[0098] The working principle of the support mechanism 10 of this device is as follows:

[0099] When the brush holder assembly to be inspected needs to be placed, the assembly is first placed between the positioning chucks 106b on the movable table 101, and the conduction motor 105c is started to drive the threaded column 105b to rotate, so that the auxiliary part 105a and one positioning chuck 106b thereon are moved closer to the other positioning chuck 106b, thereby clamping the brush holder assembly, and the transmission motor 104 is started to drive the threaded rod 103 to rotate, thereby driving the movable table 101 to move to the predetermined position along the guide rail to ensure that the surface of the brush holder assembly is in good contact with the friction member 7. During the inspection process, the working position of the friction member 7 can be adjusted by the adjustment mechanism 9 as needed, and the control mechanism 105 can be used for fine adjustment to ensure the best contact state. After the inspection is completed, the above steps are reversed, the clamping mechanism 106 is released, and the brush holder assembly is removed to complete the inspection process;

[0100] Through the two-stage adjustment mechanism of the threaded rod 103 and the threaded column 105b, very fine position adjustment of the brush holder assembly can be achieved, ensuring the accuracy of detection. The movable platform 101 adopts a high-precision linear slide rail design, combined with the guiding role of the conductive part 102, to ensure stability and straightness during movement. The clamping mechanism 106 uses a coaxially mounted positioning chuck 106b, which can quickly and firmly clamp brush holder assemblies of various sizes, simplifying the clamping process.

[0101] The anti-wear detection device of the brush holder assembly of the present invention has common mechanical installation, connection or setting methods, and any method that can achieve beneficial effects can be implemented.

[0102] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
