Description

Technical Field

[0001] This invention relates to the field of clutch friction plate measurement technology, specifically to a device and method for measuring the group height of clutch friction plates. Background Technology

[0002] The multi-plate clutch friction plate assembly is the core power transmission component of the multi-plate clutch. Relying on the friction force generated by the pressing of multiple sets of alternating friction plates, it realizes the transmission and disconnection of power between transmission systems. It can increase torque capacity, ensure smooth and continuous power output, achieve precise torque distribution in the four-wheel drive system of automobiles, improve the passability of complex road conditions, and also protect the transmission system by slipping under overload.

[0003] The axial total height of a multi-plate clutch friction plate assembly is a key dimensional parameter affecting the clutch assembly clearance, torque transmission, and operational reliability. Traditional measurement methods often involve calculating the height of individual friction plates or steel plates by stacking their thicknesses, or using a universal height gauge to directly measure the assembly of parts without load. These methods have the following drawbacks: large measurement errors, inability to apply axial loads, low operational efficiency, and poor versatility. To address these problems, this invention provides a device and method for measuring the height of a friction plate assembly, enabling random checks of the friction plate assembly height without the use of pneumatic tooling.

[0004] Combining the above issues, we find that existing products on the market are difficult to avoid all of these problems simultaneously during use. Even if they can be solved, they require external tools, thus failing to achieve the desired effect. Therefore, we propose a clutch friction plate group height measuring device and method.

[0016] A method for measuring the height of a clutch friction plate assembly includes the following steps:

[0017] S1. Base installation: Install the fixing frame on the supporting structure, such as a table, support frame, wall, etc., and adjust the base to a horizontal position through the first adjustment component and the second adjustment component;

[0018] S2. Component clamping: Place the group of friction pads to be tested on the base in the actual assembly sequence, and use the support components to support and position the friction pads to be tested to ensure that the friction pads to be tested are not misaligned and free of foreign objects on the base;

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1.

It has a high degree of working condition matching, and the efficiency of single-group measurement is greatly improved, meeting the cycle time requirements of mass production. In addition, the loading process is stable and controllable, the measurement steps are standardized, reducing human operation errors and safety risks, and making the operation process convenient and safe.

[0025] 2. When the elevation guide is placed on the base, the present invention can effectively limit the elevation guide by the positioning component, ensuring that the elevation guide is in the standard position every time it is installed. Furthermore, the positioning frame can effectively limit the push plate, improving the accuracy of the push plate position and further improving the accuracy when the push plate applies load, thereby improving the measurement accuracy.

[0026] 3. After the fixing frame is installed in the required position, the first adjustment component can adjust the horizontal position of the connecting frame, and the second adjustment component can adjust the horizontal position of the base, thereby effectively ensuring that the base is in a horizontal position after installation, avoiding the problem of the base being tilted during measurement and affecting the measurement accuracy.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figures 1-8 The present invention provides a technical solution: a device and method for measuring the height of a clutch friction plate group, including a base 1, a plurality of friction plates 101 to be measured are attached to the surface of the base 1, and a measuring mechanism 2 is provided on the surface of the base 1;

[0039] The measuring mechanism 2 includes a push plate 21, which abuts against the surfaces of several friction pads 101 to be measured. A central rod 22 is fixedly connected to the side of the push plate 21 opposite to the base 1. One end of the central rod 22 slides through the several friction pads 101 to be measured and the base 1. A hook 23 is attached to one end of the central rod 22, and a weight 24 is attached to one end of the hook 23. A leveling frame 25 is provided on the surface of the base 1. A positioning component 28 is provided on one side of the leveling frame 25. A high-precision digital depth gauge 26 abuts against the surface of the leveling frame 25. One end of the high-precision digital depth gauge 26 slides through the leveling frame 25. An opening is formed on the surface of the push plate 21. The base 1 has a groove 27, and one end of a high-precision digital depth gauge 26 passes through the groove 27 and abuts against the surface of one of the friction plates 101 to be measured. A support component 29 is provided on the surface of the base 1, and the support component 29 abuts against the inner wall of several friction plates 101 to be measured. An installation mechanism 3 is provided on one side of the base 1. The weight 24 can be replaced with standard weights 24 of different weights as needed. The high-precision digital depth gauge 26 is a mature product in the prior art and will not be described in detail here. The elevation frame 25 has a hole for the measuring end of the high-precision digital depth gauge 26 to pass through the elevation frame 25.

[0040] When measuring a group of friction plates 101, the base 1 is installed in the required position using the mounting mechanism 3 and adjusted to a horizontal position. The group of friction plates 101 are then placed on the base 1 according to their actual assembly sequence. The support assembly 29 supports and positions the friction plates 101, ensuring they are free from misalignment and foreign objects on the base 1. After the group of friction plates 101 is placed, the push plate 21 is placed on the topmost friction plate 101, and one end of the center rod 22 passes through the group of friction plates 101 and the base 1. A standard weight 24 is suspended from one end of the center rod 22 via the hook 23, allowing the push plate 21 to apply pressure to the group of friction plates 101. The load is applied, and then the leveling frame 25 is placed on the base 1. The leveling frame 25 and the push plate 21 are positioned by the positioning component 28 to improve the accuracy of the load applied by the push plate 21. Then, the high-precision digital depth gauge 26 is horizontally pressed against the top of the leveling frame 25, so that the measuring end of the high-precision digital depth gauge 26 passes through the leveling frame 25 and the groove 27 and presses against the uppermost friction piece 101 to be tested. The distance between the uppermost friction piece 101 to be tested and the top of the leveling frame 25 is measured, which is the total height of the group of friction pieces 101 to be tested under the set load. After the measurement is completed, the leveling frame 25, the weight 24 and the push plate 21 are unloaded. After the group of friction pieces 101 to be tested is removed, the measurement of the next group of friction pieces 101 to be tested can be carried out.

[0041] As a further definition of the support component 29 of the present invention, the support component 29 includes two connecting grooves 2901, which are respectively opened on both sides of the surface of the base 1. A connecting rod 2902 is fixedly connected inside each of the two connecting grooves 2901. A connecting block 2903 is slidably sleeved on the surface of the connecting rod 2902. A spring 2904 is fixedly connected to the side of the connecting block 2903 opposite to the inner wall of the connecting groove 2901. A vertical rod 2905 is fixedly connected to the surface of the connecting block 2903, and the surface of the vertical rod 2905 abuts against the inner wall of a plurality of friction pads 101 to be tested. When the friction plate 101 is placed on the base 1, pull the two vertical rods 2905 towards the middle of the base 1, and then place the friction plate 101 to be tested on the base 1. At this time, release the vertical rods 2905, and stabilize the position of the spring 2904 through the connecting rod 2902 to prevent the spring 2904 from twisting or deforming, so that the spring 2904 can support the connecting block 2903. The connecting block 2903 supports the friction plate 101 to be tested through the vertical rods 2905, so as to support and position the friction plate 101 to be tested, and can be adapted to friction plates 101 of different specifications.

[0042] The specific implementation method of this embodiment is as follows: When it is necessary to measure a group of friction plates 101 to be tested, the base 1 is installed in the required position through the mounting mechanism 3 and the base 1 is adjusted to a horizontal position. Then, the group of friction plates 101 to be tested are placed on the base 1 in the actual assembly sequence. When the friction plates 101 to be tested are placed on the base 1, the vertical rods 2905 on both sides are pulled towards the middle of the base 1. Then, the friction plates 101 to be tested are placed on the base 1. At this time, the vertical rods 2905 are released, and the position of the spring 2904 is stabilized by the connecting rod 2902 to prevent the spring 2904 from twisting or deforming. The spring 2904 supports the connecting block 2903, and the connecting block 2903 supports the friction plates 101 to be tested through the vertical rod 2905, so as to support and position the friction plates 101 to be tested, ensuring that the friction plates 101 to be tested are not misaligned or have foreign objects on the base 1. After the group of friction plates 101 to be tested is placed, the push plate 21 is placed on the base 1. The uppermost friction pad 101 is placed on the ground, and one end of the central rod 22 passes through the group of friction pads 101 and the base 1. A standard weight 24 is suspended from one end of the central rod 22 by a hook 23, so that the push plate 21 applies a load to the group of friction pads 101. Then, the leveling frame 25 is placed on the base 1, and the leveling frame 25 and the push plate 21 are positioned by the positioning component 28 to improve the accuracy of the load applied by the push plate 21. Then, the high-precision digital depth gauge 26 is horizontally pressed against the leveling frame. The measuring end of the high-precision digital depth gauge 26 is inserted through the leveling frame 25 and the groove 27 and abuts against the uppermost friction plate 101 to be tested. The distance between the uppermost friction plate 101 to be tested and the top of the leveling frame 25 is measured, which is the total height of the group of friction plates 101 to be tested under the set load. After the measurement is completed, the leveling frame 25, the weight 24 and the push plate 21 are unloaded. After the group of friction plates 101 to be tested is removed, the measurement of the next group of friction plates 101 to be tested can be carried out.

[0044] As a further definition of the positioning component 28 of the present invention, the positioning component 28 includes two positioning frames 2803, which are slidably connected to both ends of one side of the leveling frame 25. A locking block 2804 is fixedly installed at one end of each positioning frame 2803. Slots 2805 are provided on both sides of the surface of the push plate 21. The surface of the locking block 2804 is slidably connected to the inner cavity of the slot 2805. A positioning rod 2806 is fixedly connected to the side of the positioning frame 2803 opposite to the base 1.

A positioning block 2801 is fixedly installed on one side of the base 1. A positioning groove 2802 is opened on the side of the leveling frame 25 opposite to the base 1. The surface of the positioning block 2801 is slidably connected to the inner cavity of the positioning groove 2802. When the leveling frame 25 is placed on the base 1, the leveling frame 25 can be placed in the standard position through the positioning block 2801 and the positioning groove 2802. At the same time as the leveling frame 25 is placed, the positioning frame 2803 drives the locking block 2804 to be inserted into the inside of the locking groove 2805. The positioning sleeve 2807 and the positioning rod 2806 stabilize the position of the positioning frame 2803, so that the positioning frame 2803 plays a positioning role for the push plate 21, improving the position accuracy of the push plate 21.

A bracket 2811 is fixedly installed on the side of the positioning frame 2803 opposite to the base 1. Support wheels 28 are rotatably installed on both the bracket 2811 and the side of the positioning frame 2803 opposite to the leveling frame 25. 12. The surface of the support wheel 2812 abuts against one side of the leveling frame 25; the slider 2809 is slidably connected to the inside of the slide groove 2808, and the position of the slider 2809 is stabilized by the slide rod 2810, so that the positioning frame 2803 can move longitudinally, and the support bracket 2811 supports the positioning frame 2803, and the support wheel 2812 avoids friction between the positioning frame 2803 and the leveling frame 25, so that the positioning frame 2803 is more stable during longitudinal displacement, and the positioning frame 2803 can be adapted to groups of friction plates 101 of different heights.

[0046] The specific implementation of this embodiment is as follows: When the leveling frame 25 is placed on the base 1, the leveling frame 25 can be placed in a standard position by the positioning block 2801 and the positioning groove 2802. At the same time as the leveling frame 25 is placed, the positioning frame 2803 drives the locking block 2804 to be inserted into the groove 2805. The positioning sleeve 2807 and the positioning rod 2806 stabilize the position of the positioning frame 2803, so that the positioning frame 2803 can position the push plate 21, improve the position accuracy of the push plate 21, and slide the slider 2809 inside the slide groove 2808.

[0047] Example 3: Please refer to Figures 1-8 The present invention provides a technical solution: a device and method for measuring the height of a clutch friction plate assembly. The present invention makes corresponding improvements to address the technical problems mentioned in the background art.

[0048] As a further definition of the installation mechanism 3 of the present invention, the installation mechanism 3 includes a fixed frame 31 and a connecting frame 32. The connecting frame 32 is rotatably mounted on one side of the surface of the fixed frame 31. A first adjustment component 33 is provided on the other side of the surface of the fixed frame 31. The first adjustment component 33 works in conjunction with the connecting frame 32. The base 1 is rotatably mounted on the surface of the connecting frame 32. A bracket 34 is fixedly mounted on one side of the connecting frame 32. A second adjustment component 35 is provided on the surface of the bracket 34. The second adjustment component 35 works in conjunction with the base 1. By installing the fixed frame 31 in the required position, such as a table, support frame, or wall, the fixed frame 31 supports the position of the base 1 through the connecting frame 32 and the bracket 34. Then, the horizontal position of the connecting frame 32 is adjusted by the first adjustment component 33, and the horizontal position of the base 1 is adjusted by the second adjustment component 35, so that the base 1 remains in a horizontal position after installation, avoiding problems such as tilting of the base 1 that could cause a deviation in the load application direction.

[0049] The first adjustment component 33 includes a first movable groove 3301, which is formed on the other side of the surface of the fixed frame 31. A first screw 3302 is rotatably connected to one side of the fixed frame 31. One end of the first screw 3302 passes through the fixed frame 31 and is rotatably connected to the inner cavity of the first movable groove 3301. A first movable block 3303 is threaded onto the surface of the first screw 3302. One end of the first movable block 3303 passes through the first movable groove 3301. A first movable frame 3304 is fixedly installed on one end of the first movable block 3303. A first movable bracket 3304 is rotatably installed inside the first movable frame 3304. A roller 3305, a first inclined block 3306 is fixedly installed on the side of the connecting frame 32 opposite to the fixed frame 31, the surface of the first roller 3305 abuts against the surface of the first inclined block 3306; a first limiting block 3307 is fixedly installed on one end of the first screw 3302, the first limiting block 3307 is rotatably connected to the inside of the fixed frame 31; a support block 3308 is fixedly installed on the side of the first movable frame 3304 opposite to the fixed frame 31, a support groove 3309 is opened on the side of the fixed frame 31 opposite to the first movable frame 3304, and the support block 3308 is slidably connected to the inside of the support groove 3309;

[0050] By rotating the first screw 3302 and stabilizing its position with the first limiting block 3307, the first screw 3302 drives the first moving block 3303 to move inside the first moving groove 3301. This causes the first moving block 3303 to move the first moving frame 3304 simultaneously. The support block 3308 and the support groove 3309 stabilize the position of the first moving frame 3304, preventing it from tilting or shifting. The first moving frame 3304 then drives the rollers to move on the surface of the first inclined block 3306. The first moving frame 3304 drives the first rollers 3305 to different positions on the surface of the first inclined block 3306. The inclined surface of the first inclined block 3306 allows the first moving frame 3304 and the first rollers 3305 to support one side of the connecting frame 32 at different heights, thereby adjusting the horizontal position of the connecting frame 32.

[0051] The second adjustment assembly 35 includes two second moving slots 3501, which are respectively formed on both sides of the surface of the bracket 34. A second moving block 3502 is slidably connected inside the second moving slot 3501. One end of the second moving block 3502 passes through the second moving slot 3501, and a second moving frame 3503 is fixedly installed at one end of the second moving block 3502. A second roller 3504 is rotatably installed inside the second moving frame 3503. A second inclined block 3505 is fixedly installed on the side of the base 1 opposite to the bracket 34. The surface of the second roller 3504 abuts against the surface of the second inclined block 3505. A moving plate 3506 is fixedly connected to the opposite side of the two second moving blocks 3502. A second screw 3507 is rotatably connected to one side of the bracket 34. One end of the second screw 3507 passes through the bracket 34 and the movable plate 3506, and the movable plate 3506 is threaded onto the surface of the second screw 3507; a second limiting block 3508 is fixedly installed at one end of the second screw 3507, and the second limiting block 3508 is rotatably connected to the inside of the bracket 34. A limiting rod 3509 is fixedly connected inside the bracket 34, and the movable plate 3506 is slidably sleeved on the surface of the limiting rod 3509. A second limiting block 3508 is fixedly installed at one end of the second screw 3507, and the second limiting block 3508 is rotatably connected to the inside of the bracket 34. Guide frames 3510 are fixedly installed on both sides of the second movable frame 3503, and guide blocks 3511 are fixedly installed on the surface of the bracket 34. Guide frames 3510 are slidably sleeved on the surface of guide blocks 3511.

[0052] By rotating the second screw 3507 and stabilizing its position with the second limiting block 3508, and stabilizing the position of the moving plate 3506 with the limiting rod 3509, the second screw 3507 drives the moving plate 3506 to move. This causes the moving plate 3506 to drive the second moving block 3502 to move inside the second moving groove 3501, thereby causing the second moving block 3502 to drive the second moving frame 3503 to move. The guide frame 3510 and guide block 3511 stabilize the position of the second moving frame 3503, causing the second moving frame 3503 to drive the second roller 3504 to move on the surface of the second inclined block 3505. By moving the second moving frame 3503 and the second roller 3504 to different positions on the surface of the second inclined block 3505, one side of the base 1 can be adjusted to different heights, thus achieving the effect of adjusting the horizontal position of the base 1.

[0053] The specific implementation of this embodiment is as follows: By installing the fixing frame 31 at the required position, such as a tabletop, support frame, or wall, the fixing frame 31, through the connecting frame 32 and the bracket 34, supports the position of the base 1. Then, the first screw 3302 is rotated, and the position of the first screw 3302 is stabilized by the first limiting block 3307, causing the first screw 3302 to drive the first moving block 3303 to move inside the first moving groove 3301. This causes the first moving block 3303 to drive the first moving frame 3304 to move simultaneously, and through the support block 330... 8 and the support groove 3309 stabilize the position of the first movable frame 3304, preventing the first movable frame 3304 from tilting or shifting. This allows the first movable frame 3304 to drive the rollers to move on the surface of the first inclined block 3306. The first movable frame 3304 then drives the first rollers 3305 to different positions on the surface of the first inclined block 3306. The inclined surface of the first inclined block 3306 allows the first movable frame 3304 and the first rollers 3305 to support one side of the connecting frame 32 to different heights, thereby achieving... The function of adjusting the horizontal position of the connecting frame 32 is to rotate the second screw 3507, and stabilize the position of the second screw 3507 by the second limit block 3508, and stabilize the position of the moving plate 3506 by the limit rod 3509. This causes the second screw 3507 to drive the moving plate 3506 to move, which in turn causes the moving plate 3506 to drive the second moving block 3502 to move inside the second moving groove 3501. This causes the second moving block 3502 to drive the second moving frame 3503 to move, and stabilizes the second moving frame 3503 through the guide frame 3510 and guide block 3511. The position of the frame 3503 allows the second movable frame 3503 to drive the second roller 3504 to move on the surface of the second inclined block 3505. By moving the second movable frame 3503 and the second roller 3504 to different positions on the surface of the second inclined block 3505, one side of the base 1 can be adjusted to different heights. Then, through the cooperation of the first adjusting component 33 and the second adjusting component 35, the horizontal position of the base 1 can be adjusted, so that the base 1 is kept in a horizontal position after installation, avoiding problems such as tilting of the base 1 that would cause the load application direction to deviate.

[0054] A method for measuring the height of a clutch friction plate assembly includes the following steps:

[0055] S1. Base 1 installation: Install the fixing frame 31 on the supporting structure, such as a table, support frame, wall, etc., and adjust the base 1 to a horizontal position through the first adjusting component 33 and the second adjusting component 35.

[0056] S2. Component clamping: The group of friction plates 101 to be tested are placed on the base 1 in the actual assembly sequence, and the friction plates 101 to be tested are supported and positioned by the support component 29 to ensure that the friction plates 101 to be tested are not misaligned and free of foreign objects on the base 1.

[0057] S3. Push plate 21 installation: Place push plate 21 on the group of friction plates to be tested 101, ensuring that push plate 21 is fully engaged with the uppermost friction plate to be tested 101, and that the center rod 22 passes through the group of friction plates to be tested 101 and the base 1.

[0058] S4. Load application: Hook 23 is attached to one end of the center rod 22, and then the standard weight 24 is suspended on the hook 23, so that the standard weight 24 exerts downward pressure on the push plate 21 through the hook 23 and the center rod 22, so that the push plate 21 applies a stable load to the group of friction plates 101 to be tested.

[0059] S5. Height measurement: Place the elevation frame 25 on the base 1 and set up the high-precision digital display depth gauge 26 on the elevation frame 25. Measure the distance between the topmost friction plate 101 to be tested and the top of the elevation frame 25. This is the total height of the group of friction plates 101 to be tested under the set load.

[0060] S6. Data recording and unloading: Read and record the measurement data, unload the weight 24 and hook 23, and then remove the push plate 21 to complete the measurement.
