Description

Technical Field

[0001] This invention relates to the field of clutch plate testing, and specifically to an automotive clutch plate testing device and testing method. Background Technology

[0002] The thickness of the clutch plate is crucial to the normal operation and safety performance of a vehicle. When the clutch plate is severely worn and its thickness becomes significantly thinner, problems such as vehicle shaking when starting in first gear, difficulty shifting gears, abnormal vehicle vibration, and slippage may occur, affecting the smooth transmission of power and normal driving. Moreover, when the clutch plate thickness exceeds the standard value, it needs to be replaced in time. Therefore, accurately measuring the clutch plate thickness can help determine its degree of wear, facilitate timely replacement, and ensure the safe and stable operation of the vehicle.

[0003] Existing technologies involve some gear component testing devices that clamp the gear by using a chuck protrusion to engage with the gear keyway and a chuck pin to limit the movement of the gear with an annular groove. A spring force is used to bring the probe into contact with the gear to measure its thickness. However, automotive clutch plates and gears have different shapes, and the fixtures used for gears cannot effectively position and clamp the clutch plate. The clutch plate cannot receive stable support and positioning during measurement, leading to significant errors in parameter acquisition. Furthermore, clutch plate testing requires multi-point data collection, and current testing devices struggle to accurately adjust the orientation of the component under test, making it difficult to guarantee the accuracy of multi-point data collection when adjusting the clutch plate position, thus affecting the efficiency of clutch plate testing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automotive clutch plate testing device and method. Through the cooperation of a positioning plate and a clamping plate, stable clamping of the clutch plate is achieved, preventing shaking or displacement during testing, thereby reducing testing errors and improving accuracy. A rotary drive mechanism can rotate the positioning plate, enabling the probe to perform multi-point testing of the clutch plate. The orientation component orients the outer ring teeth of the clutch plate through orientation blocks, ensuring accurate positioning of the clutch plate during clamping and thus guaranteeing the reliability of the testing data.

[0005] The first objective of this invention is to provide an automotive clutch plate detection device, which employs the following solution: include: The fixture includes a positioning plate and a clamping plate arranged opposite to each other. One end of the positioning plate is connected to a rotary drive mechanism, and the other end forms a positioning part that engages with a clutch plate. The end of the clamping plate away from the positioning plate is connected to a lifting drive mechanism to adjust the distance between the positioning plate and the clamping plate. The detection component includes a probe that runs parallel to the axial direction of the positioning disk and a displacement sensor that measures the displacement of the probe. The probe is suspended above the edge of the positioning part. The directional assembly includes a directional block and a clearance drive mechanism. The directional block has a directional portion that accommodates the outer ring teeth of the clutch plate. The clearance drive mechanism is connected to the directional block to drive the directional block to contact or disengage from the clutch plate.

[0006] Furthermore, the end of the positioning disk is provided with a protrusion, and an annular positioning part is formed between the protrusion and the edge of the positioning disk to constrain the radial and axial positions of the mating clutch plate.

[0007] Furthermore, a clamping portion is formed between the positioning plate and the clamping plate to constrain the axial position of the clutch plate, and the probe contacts the clutch plate after passing the clamping plate.

[0008] Furthermore, the positioning plate and the pressing plate are coaxially distributed, the pressing plate is rotatably connected to the lifting drive mechanism, and the diameter of the positioning plate is larger than the diameter of the pressing plate.

[0009] Furthermore, the detection component also includes a displacement driving mechanism, which includes vertically distributed guide rails and a slider that slides with the guide rails, with the probe mounted on the slider.

[0010] Furthermore, the orientation part is a toothed groove, and the orientation block is raised and lowered under the drive of the avoidance drive mechanism so as to make the clutch plate teeth embed into the toothed groove along the axial direction parallel to the positioning disk, thereby constraining the circumferential position of the clutch plate.

[0011] Furthermore, the rotary drive mechanism, lifting drive mechanism, displacement sensor, and obstacle avoidance drive mechanism are respectively connected to the controller. The displacement sensor acquires the displacement of the probe relative to the initial point and sends it to the controller.

[0012] Furthermore, the controller is connected to two-hand buttons, which control the operation of the rotary drive mechanism and the lifting drive mechanism when the two-hand buttons are triggered.

[0013] A second objective of the present invention is to provide a method for detecting automotive clutch plates, utilizing the automotive clutch plate detection device provided as in the first objective, comprising: The clutch plate awaiting inspection moves between the positioning plate and the clamping plate and is placed in the positioning part to cooperate with the positioning part and constrain the radial position of the clutch plate; The directional block moves and adjusts the circumferential position of the clutch plate, so that the directional part engages with the outer ring teeth of the clutch plate, thereby constraining the circumferential position of the clutch plate. The clamping plate moves and, together with the positioning plate, clamps the clutch disc to constrain its axial position. The rotary drive mechanism drives the clutch plate to rotate via the positioning disk. After the probe descends, it contacts the positioning disk and the probe's descent displacement is obtained. The thickness of the clutch plate at the probe's contact position is calculated. The positioning disk rotates multiple times at a set angle and the probe's descent displacement is obtained at each location. The thickness of the clutch plate at multiple locations is then calculated.

[0014] Furthermore, after the clutch plate is positioned radially, circumferentially, and axially, the orientation block disengages from the clutch plate, and then the probe measures the thickness of the clutch plate.

[0015] Compared with the prior art, the advantages and positive effects of this invention are: To address the current problem of incompatibility between testing equipment and clutch plate positioning, a stable clamping of the clutch plate in both the axial and radial directions is achieved through the cooperation of a positioning plate and a clamping plate. The orientation component orients the outer ring teeth of the clutch plate through orientation blocks, ensuring accurate circumferential positioning of the clutch plate during clamping and preventing shaking or displacement of the clutch plate during testing. This meets the requirements of single-testing. Combined with a rotary drive mechanism, the positioning plate can be rotated, enabling the probe to perform multi-point testing of the clutch plate without frequent adjustments to the relative position of the clutch plate and the fixture, thus improving testing efficiency.

[0016] Through multiple constraints of the annular positioning part, clamping part and tooth groove orientation, the radial, axial and circumferential position errors of the clutch plate are effectively reduced, and the stability of the test data is improved compared with traditional gear testing devices.

[0017] During clamping, the directional block rises, and the toothed groove engages with the clutch plate teeth to complete circumferential positioning. During testing, the directional block descends to avoid affecting the rotation of the clutch plate. Circumferential positioning ensures that the angle of the clutch plate is fixed during testing, which facilitates position calibration during subsequent multi-point testing and improves data consistency.

[0023] Example 1 In a typical embodiment of the present invention, such as Figures 1-3 As shown, a device for detecting automotive clutch plates is presented.

[0024] Existing gear component testing devices suffer from several drawbacks. Due to the significant difference in shape between the clutch plate 4 and the gear, effective positioning and clamping of the clutch plate 4 are impossible. This leads to unstable support and positioning during testing, large errors in measured parameters, and difficulty in accurately adjusting the orientation of the component under test to achieve multi-point data acquisition, thus affecting testing efficiency. Therefore, this embodiment provides an automotive clutch plate testing device. Through the cooperation of the positioning disc 5 and the clamping disc 3, stable axial and radial clamping of the clutch plate 4 is achieved. The orientation component, through the orientation block 7, orients the outer ring teeth of the clutch plate 4, ensuring accurate circumferential positioning of the clutch plate 4 during clamping and preventing wobbling or displacement of the clutch plate 4 during testing, thus meeting the requirements for single-test operation.

[0025] like Figures 1-3 As shown, the automotive clutch plate testing device includes a clamp, a testing component, and a positioning component. The clamp consists of a positioning plate 5 and a clamping plate 3 arranged opposite each other. One end of the positioning plate 5 is connected to a rotary drive mechanism 6, and the other end forms a positioning part for the clutch plate 4. The end of the clamping plate 3 away from the positioning plate 5 is connected to a lifting drive mechanism 1. During operation, the clutch plate 4 is first placed on the positioning part of the positioning plate 5. The distance between the clamping plate 3 and the positioning plate 5 is adjusted by the lifting drive mechanism 1, so that the clamping plate 3 presses the clutch plate 4 firmly, thereby achieving stable clamping of the clutch plate 4. The rotary drive mechanism 6 can drive the positioning plate 5 to rotate, so as to facilitate multi-point testing of the clutch plate 4.

[0026] The detection assembly includes a probe 2 that runs parallel to the axial direction of the positioning disk 5 and a displacement sensor 9 that measures the displacement of the probe 2. The probe 2 is suspended above the edge of the positioning part. After the clutch plate 4 is clamped and stabilized, the probe 2 runs parallel to the axial direction of the positioning disk 5 to detect the thickness of the clutch plate 4. The displacement sensor 9 can measure the displacement of the probe 2 in real time, thereby obtaining the thickness data of the clutch plate 4.

[0027] The orientation assembly includes an orientation block 7 and a clearance drive mechanism. The orientation block 7 has an orientation portion that accommodates the outer ring teeth of the clutch disc 4. When clamping the clutch disc 4, the clearance drive mechanism drives the orientation block 7 to move, causing the orientation portion to accommodate the outer ring teeth of the clutch disc 4, thereby orienting the clutch disc 4 and ensuring accurate positioning of the clutch disc 4 during clamping. During the testing process, the clearance drive mechanism can drive the orientation block 7 to disengage from the clutch disc 4 to avoid interfering with the testing.

[0028] Compared with the prior art, the automotive clutch plate detection device provided in this embodiment has stable positioning and clamping, and small detection error. Through the cooperation of positioning plate 5 and clamping plate 3, stable clamping of clutch plate 4 is achieved, avoiding shaking or displacement of clutch plate 4 during detection, thereby reducing detection error and improving detection accuracy.

[0029] Furthermore, it facilitates multi-point data acquisition and boasts high detection efficiency. The rotary drive mechanism 6 can drive the positioning disk 5 to rotate, enabling the probe 2 to perform multi-point detection on the clutch plate 4 without frequent adjustments to its position, thus improving detection efficiency. The orientation component uses the orientation block 7 to orient the outer ring teeth of the clutch plate 4, ensuring the accurate positioning of the clutch plate 4 during clamping and guaranteeing the reliability of the detection data.

[0030] In this embodiment, the protrusion 12 at the end of the positioning disk 5 forms an annular positioning part with its edge, achieving dual constraints through geometric structure. Radially, the protrusion 12 and the edge of the positioning disk 5 form an annular space, restricting the radial movement of the clutch plate 4 and ensuring that its center is coaxial with the positioning disk 5, thus avoiding data deviation due to eccentricity during testing. Axially, the height difference of the positioning part, combined with the clamping force of the pressure plate 3, fixes the clutch plate 4 from the top and bottom, preventing axial movement. During operation, after the clutch plate 4 is placed in the positioning part, the protrusion 12 engages with the inner edge, the edge of the positioning disk 5 supports the outer side, and then the pressure plate 3 descends to form a clamping part, fixing the clutch plate 4 with pressure.

[0031] The clamping part between the positioning plate 5 and the clamping plate 3 strengthens axial positioning. The probe 2 passes over the positioning plate 5 to contact the clutch plate 4. The clamping part ensures the axial position of the clutch plate 4 is stable through uniform pressure. The probe 2 directly contacts the target surface, avoiding interference from the positioning structure and ensuring the accuracy of the detection data. The distribution of the probe 2 allows the detection path to avoid the clamping plate 3, reducing errors caused by contact and collision.

[0032] The positioning disk 5 and the clamping disk 3 are coaxially distributed, and the diameter of the positioning disk 5 is larger than that of the clamping disk 3. The coaxial design ensures that the center position of the clutch plate 4 remains unchanged when it rotates, which facilitates the coordinate unification during multi-point detection. The diameter difference allows the positioning disk 5 to provide a wider support surface for the clutch plate 4, while avoiding the clamping disk 3 from blocking the outer ring teeth, which facilitates the operation of the orientation component.

[0033] like Figure 2 and Figure 3 As shown, the detection component drives the probe 2 to move via the vertical guide rail 10 and the slider. The slider slides along the axial direction of the guide rail 10, causing the probe 2 to scan different positions of the clutch plate 4 parallel to the axis of the positioning disk 5. The displacement sensor 9 records the displacement of the probe 2 in real time and calculates the thickness based on the initial position. The position of the probe 2 can be precisely adjusted to meet the detection needs of different areas such as the edge and center of the clutch plate 4, avoiding errors caused by manual adjustment.

[0034] The groove 11 of the directional block 7 matches the shape of the outer ring teeth of the clutch plate 4. Positioning is achieved by raising and lowering the directional block 7 through a clearance drive mechanism. During clamping, the directional block 7 rises to engage the groove 11 with the teeth of the clutch plate 4, restricting circumferential rotation. During testing, the directional block 7 lowers to avoid interference with the rotation of the clutch plate 4. Circumferential positioning ensures that the angle of the clutch plate 4 is fixed, facilitating position calibration during multi-point testing and improving data consistency.

[0035] Each drive mechanism and sensor is connected to the controller to form a closed-loop control. The displacement sensor 9 transmits the displacement data of the probe 2 to the controller in real time. The controller judges whether the thickness is qualified according to the preset parameters. If it exceeds the error range, an alarm is triggered. At the same time, the actions of each mechanism are coordinated. For example, after pressing, the rotary drive mechanism 6 is automatically started, so that the clutch plate 4 rotates to the specified detection angle.

[0036] The controller is connected to a two-hand button, which drives the mechanism only when both hands are pressed simultaneously. This prevents accidental activation during single-person operation, ensures that the operator's hands are kept away from dangerous areas, complies with industrial safety regulations, and avoids the risk of mechanical injury.

[0037] The annular positioning part, clamping part, and toothed groove 11 provide radial, axial, and circumferential triple constraints, ensuring the stability of the clutch plate 4 during clamping and avoiding errors caused by shaking during the testing process. The coaxial and diameter difference design ensures the concentricity of the clutch plate 4 during rotation, providing a unified benchmark for multi-point testing.

[0038] The displacement drive mechanism, in conjunction with the controller, enables automatic scanning of the probe 2, reducing manual adjustment steps. The rotary drive mechanism 6 drives the clutch plate 4 to rotate, eliminating the need for manual adjustment of the detection position and improving detection efficiency. The combination of a two-hand button triggering mechanism and automated control standardizes the operating procedure and reduces efficiency losses caused by human intervention.

[0039] The avoidance design of the directional block 7 avoids mechanical interference during the testing process and reduces the risk of equipment failure; the controller monitors data in real time to ensure the traceability of the testing process and improve the reliability of quality control.

[0040] In this embodiment, the lifting drive mechanism 1 consists of a servo motor, a ball screw, and a linear guide rail 10. The motor is connected to the ball screw via a coupling, and the ball screw nut drives the clamping plate 3 to rise and fall along the guide rail 10. After receiving a control signal, the motor drives the ball screw to rotate, causing the clamping plate 3 to move vertically up and down, thereby clamping and releasing the clutch plate 4.

[0041] The rotary drive mechanism 6 uses a stepper motor paired with a harmonic reducer, and the motor shaft is rigidly connected to the central shaft of the positioning disk 5. Rotating the positioning disk 5 at a preset angle (e.g., 30°) drives the clutch plate 4 to rotate, so that the probe 2 can perform multi-point detection.

[0042] The avoidance drive mechanism is a cylinder-driven structure, comprising a cylinder, a piston rod, and a guide block 7. The cylinder controls the air path via a solenoid valve. During positioning, the cylinder pushes the guide block 7 upward, causing the tooth groove 11 to engage with the teeth of the clutch plate 4; during detection, the cylinder pulls the guide block 7 downward, disengaging it from the clutch plate 4 to avoid interference.

[0043] The displacement drive mechanism uses a servo motor to drive the linear guide rail 10 slider. The probe 2 is fixed below the slider and is used with a grating ruler to measure displacement. The probe 2 is driven to move up and down along the axial direction of the positioning disk 5, contact the surface of the clutch plate 4 and collect displacement data to calculate the thickness.

[0044] Example 2 In another typical embodiment of the present invention, such as Figures 1-3 As shown, a method for detecting automobile clutch plates is presented, utilizing the automobile clutch plate detection device as described in Example 1.

[0045] A method for detecting automotive clutch plates includes: The clutch plate 4 awaiting inspection moves between the positioning plate 5 and the clamping plate 3, and is placed in the positioning part to cooperate with the positioning part, constraining the radial position of the clutch plate 4; The directional block 7 moves and adjusts the circumferential position of the clutch plate 4 so that the directional part engages with the outer ring teeth of the clutch plate 4, thereby constraining the circumferential position of the clutch plate 4. The clamping plate 3 moves and, together with the positioning plate 5, clamps the clutch plate 4 to constrain the axial position of the clutch plate 4; The rotary drive mechanism 6 drives the clutch plate 4 to rotate through the positioning disk 5. After the probe 2 descends, it contacts the positioning disk 5 and obtains the downward displacement of the probe 2. The thickness of the clutch plate 4 at the contact position of the probe 2 is calculated. The positioning disk 5 rotates multiple times at a set angle and obtains the downward displacement of the probe 2 at each time. The thickness of the clutch plate 4 at multiple locations is calculated.

[0046] After the clutch plate 4 is positioned radially, circumferentially and axially, the orientation block 7 disengages from the clutch plate 4, and then the probe 2 measures the thickness of the clutch plate 4.

[0047] Specifically, in combination Figures 1-3 This paper provides a detailed explanation of the testing methods for automotive clutch plates.

[0048] Radial positioning is achieved through the geometric adaptation of the annular positioning part. When the clutch plate 4 is placed on the annular positioning part of the positioning disk 5, the annular space formed by the protrusion 12 at the end of the positioning disk 5 and the edge.

[0049] The raised 12 engages the inner edge of the clutch plate 4, while the edge of the positioning disk 5 supports the outer side, ensuring that the center of the clutch plate 4 is coaxial with the axis of the positioning disk 5, with the error controlled within 0.05mm. This mechanical limiting principle prevents thickness data deviations caused by radial offset of the clutch plate 4 during the testing process.

[0050] Circumferential positioning relies on the precise engagement of the tooth groove 11 of the directional block 7. The directional block 7 moves by avoiding the drive mechanism, and its tooth groove 11 engages with the outer ring teeth of the clutch plate 4.

[0051] When the directional block 7 rises, the tooth groove 11 engages with the teeth of the clutch plate 4, restricting circumferential rotation and ensuring that the angle of the clutch plate 4 is fixed. This step, through shape matching of the mechanical structure, solves the problem that traditional gear detection devices cannot position the clutch plate 4 circumferentially, providing an angular reference for subsequent multi-point detection.

[0052] Axial positioning is achieved through pressure fixation of the clamping part. The clamping plate 3 descends under the action of the lifting drive mechanism 1, forming a clamping part with the positioning plate 5. The pressure of the clamping plate 3 is evenly distributed along the axis of the clutch plate 4, and the height difference of the positioning part eliminates axial movement clearance. This design enhances positioning stability through mechanical clamping force, ensuring that the probe 2 will not produce detection errors due to axial displacement when it contacts the clutch plate 4.

[0053] When probe 2 descends and contacts clutch plate 4, displacement sensor 9 records its displacement relative to the initial point. The thickness calculation logic is as follows: The initial distance between the probe 2 and the surface of the positioning disk 5 is a fixed value H. After contacting the clutch plate 4, the displacement is Δh. Therefore, the thickness of the clutch plate 4 is t = H - Δh. This formula directly converts the displacement data into a thickness value through geometric relationships, avoiding errors from manual readings.

[0054] The rotary drive mechanism 6 drives the positioning disk 5 to rotate at a set angle (e.g., 30° each time) to achieve multi-point detection. The controller presets a rotation angle sequence, and the positioning disk 5 automatically locks after each rotation. The probe 2 then descends to collect data. By automatically adjusting the angle, the traditional manual point-finding method is replaced, ensuring that the detection points are evenly distributed around the circumference of the clutch plate 4, thus improving the representativeness of the data.

[0055] After completing the three-dimensional positioning, the orientation block 7 descends and disengages from the clutch plate 4, avoiding interference from the orientation block 7 on the rotation of the clutch plate 4, and simultaneously preventing mechanical collision between the probe 2 and the orientation block 7 during scanning. This step, through timing control (positioning → avoidance → detection), ensures that each mechanism works collaboratively at different stages, improving the reliability of the detection process.

[0056] During the positioning stage, clutch plate 4 is placed in the positioning part, and radial positioning is completed; directional block 7 rises, and tooth groove 11 engages with the teeth of clutch plate 4, and circumferential positioning is completed; clamping plate 3 descends, and clamping part fixes clutch plate 4, and axial positioning is completed.

[0057] The three-dimensional positioning is performed in the order of "radial → circumferential → axial", with each step providing a positioning reference for the next step to ensure the superposition of constraint effects.

[0058] During the detection phase, the orientation block 7 descends to avoid obstacles, and the probe 2 moves above the positioning disk 5; the positioning disk 5 rotates to a first set angle (e.g., 0°), and the probe 2 descends to collect data; the positioning disk 5 rotates to angles such as 30° and 60° in sequence, and the data collection is repeated. The directional block 7 and the probe 2 are interlocked to avoid interference between the mechanisms; the angle rotation and data acquisition are triggered synchronously by the controller to ensure time accuracy.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
