Description

Technical Field

[0001] This invention relates to the field of clutch pressure plate enlargement technology, and more particularly to a motorcycle clutch pressure plate enlargement device. Background Technology

[0002] A clutch is a device that can separate the engine from the wheel transmission. The clutch includes a clutch pressure plate, and the clutch pressure plate needs to be replaced after a certain mileage to ensure the normal operation of the vehicle. In the manufacturing process of motorcycle clutch pressure plates, if the diameter of the pressure plate to be replaced is too small, it will affect the installation effect of the pressure plate. Therefore, a pressure plate enlarging device is needed to enlarge the hole of the pressure plate.

[0003] Traditional motorcycle clutch pressure plate enlarging devices mostly use simple clamping or positioning methods to fix the pressure plate, which cannot quickly and accurately fix the pressure plate and affect the enlarging efficiency of the pressure plate. Therefore, corresponding improvements have been made to address this problem. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a device for expanding the pressure plate of a motorcycle clutch.

[0005] This invention discloses a motorcycle clutch pressure plate reaming device, comprising a base plate and a mounting platform. Multiple telescopic legs are fixed to the top corners of the base plate, and a pair of electric actuators are fixed to the top of the base plate. The free ends of the telescopic legs and electric actuators are respectively fixedly connected to the mounting platform. Grooves are respectively formed on the inner walls of both sides of the mounting platform. The device also includes an x-axis platform above the mounting platform, a y-axis platform fixedly connected to the free end of the x-axis platform, and a fixing frame fixedly connected to the free end of the y-axis platform. A motor is fixedly connected to the fixing frame, and a reaming drill bit is mounted on the motor output shaft. An anti-deviation mechanism is provided on the mounting platform to prevent the pressure plate from shifting during reaming. X-axis displacement: The pressure plate is placed between the two slots, positioning it in the middle of the mounting platform. This prevents the pressure plate from moving in the Y and Z directions. Then, an anti-offset mechanism is inserted into two of the circular holes on the pressure plate to restrict its movement along the length of the mounting platform, i.e., the X-axis. This allows for quick and easy fixation of the pressure plate. After fixation, the X-axis and Y-axis platforms drive the reaming drill bit to move above the corresponding circular hole. Then, the motor starts, causing the reaming drill bit to rotate. Finally, the electric actuator starts, moving the mounting platform and the pressure plate upwards. This allows the reaming drill bit to enter the corresponding circular hole for reaming.

[0006] Preferably, the anti-deviation mechanism includes a pair of sliders, with a pair of guide posts fixedly connected to the top of the sliders. A positioning cone that can be inserted into a circular hole on the pressure plate is slidably connected between the two guide posts. A spring is sleeved on the guide post, and the two ends of the spring are fixedly connected to the slider and the positioning cone, respectively. The pressure plate is adjusted so that the two circular holes on the pressure plate are aligned with the two positioning cones. Then the positioning cones are released, and under the action of the spring, the positioning cones are driven to move upward and insert into the corresponding circular holes, and press against the pressure plate. In this way, the two positioning cones can restrict the movement of the pressure plate along the x-direction. During the process of enlarging the circular hole into which the positioning cone is inserted, the top of the positioning cone will contact the reaming drill bit and be subjected to downward pressure. The spring will be compressed, and the positioning cone will move downward to avoid the reaming drill bit, so that the reaming drill bit can continue to enlarge the hole downward. After the hole enlargement is completed, the reaming drill bit leaves the circular hole, and the positioning cone will be inserted into the circular hole again under the action of the spring force and press against the pressure plate again with its conical surface.

[0007] Preferably, a slide rail is fixedly connected below the mounting platform, and the slider is slidably connected to the slide rail. A bidirectional screw is rotatably connected inside the slide rail and forms a threaded connection with the slider. By rotating the bidirectional screw, the two sliders are driven to move closer or further apart, thereby adjusting the distance between the two positioning cones. This allows for the adaptation to different types of clutch pressure plates.

[0008] Preferably, it also includes an actuator, which includes an air pump fixedly connected to the slide rail. The air pump's outlet is connected to a tee, and two hoses are connected to the two outlets of the tee. The positioning cone is a hollow structure with densely packed exhaust holes at different angles on its conical surface. The hoses are connected to the air inlet pipe at the bottom of the positioning cone. A pressure switch is embedded at the top of the positioning cone. Solenoid valves are installed in the two outlets of the tee, and the pressure switch is connected in series with the corresponding solenoid valve. If the pressure plate shifts during the reaming process, air can be pumped into the positioning cone. The positioning cone, subjected to the strong thrust of the airflow, will move upwards, utilizing the conical surface to... The force generated by the hole drives the pressure plate back to its initial position, achieving the effect of correction. When the round hole into which the positioning cone is inserted is enlarged and then shifts, the corresponding solenoid valve will close because the enlarging drill bit presses on the pressure switch at the top of one of the positioning cones. This prevents the positioning cone from being filled with air, thus avoiding obstruction of the enlarging drill bit. The other positioning cone remains inflated, and the pressure plate can be reset by cooperating with the enlarging drill bit inserted into the round hole. Furthermore, the airflow from the exhaust hole at different angles will blow away the debris generated by the enlargement that falls on the equipment parts, maintaining the cleanliness of the equipment.

[0009] Preferably, it further includes: a displacement acquisition module, installed on the slider and connected to the positioning cone, for real-time monitoring of the axial displacement of the positioning cone, and generating a displacement fluctuation coefficient through the control module; a torque resistance acquisition module, installed on the output shaft of the motor, for real-time monitoring of the motor output torque, and generating a torque fluctuation coefficient through the control module; the control module performs comprehensive analysis on the generated displacement fluctuation coefficient and torque fluctuation coefficient, generates an evaluation coefficient, determines whether the actuator needs to correct the pressure plate, compares the evaluation coefficient with a pre-set evaluation coefficient reference threshold, and controls the working state of the actuator based on the comparison result.

[0010] Preferably, the output and input terminals of the displacement acquisition module and the output and input terminals of the torque resistance acquisition module are electrically connected to the input and output terminals of the control module, respectively, and the output terminal of the control module is electrically connected to the input terminal of the air pump.

[0011] Preferably, the execution steps of the control module controlling the working state of the actuator based on the comparison results are as follows:

[0012] Real-time detection: The displacement acquisition module acquires the axial displacement of the positioning cone; the torque resistance acquisition module acquires the output torque of the motor.

[0013] Coefficient Calculation: The control module calculates the displacement fluctuation coefficient, torque fluctuation coefficient, and evaluation coefficient. Dynamic adjustment: If : Execution module in standby mode; if The execution module is activated, applying an additional upward thrust to the positioning cone. This is a reference threshold.

[0014] Preferably, the generation logic of the displacement fluctuation coefficient is as follows:

[0015] S1. The actual axial displacement of the positioning cone (14) at different times within time T when the reaming drill bit (10) reams the pressure plate is obtained through the displacement acquisition module (21). The actual axial displacement obtained at the i-th time within time T is calibrated as... , , It is a positive integer;

[0016] S2. Calculate the displacement fluctuation coefficient. The expression for the calculation is:

[0017]

[0018] In the formula, The average displacement over time T; The number of samples taken within time T.

[0020] S1. Obtain the actual output torque of the motor (9) at different times within time T when the reaming drill bit (10) reams the pressure plate using the torque resistance acquisition module (22). Then, calibrate the actual output torque obtained at time j within time T as follows: , , It is a positive integer;

[0021] S2. Calculate the torque fluctuation coefficient. The expression for the calculation is:

[0022]

[0023] In the formula, is the average torque over time T; m is the number of samples over time T.

[0024] Preferably, the control module performs formulaic analysis based on the following formula:

[0025]

[0026] In the formula, The evaluation coefficients are α and β, which are preset weighting coefficients. .

[0027] Compared with the prior art, the present invention provides a motorcycle clutch pressure plate enlarging device, which has the following beneficial effects:

[0028] 1. A device for enlarging a motorcycle clutch pressure plate. This invention restricts the movement of the pressure plate in the y and z directions through a groove, and restricts its movement in the x direction with an anti-deviation mechanism. This allows for quick and precise fixation of the pressure plate, effectively preventing displacement during the enlarging process and improving the stability and machining accuracy of the enlarging. Furthermore, the adjustable positioning cone design in the anti-deviation mechanism can adapt to different types of clutch pressure plates, enhancing the versatility of the device.

[0029] 2. A motorcycle clutch pressure plate reaming device, wherein the actuator enables the device to have an automatic correction function. During the reaming process, when the pressure plate shifts, air is pumped into the positioning cone via an air pump, and the force exerted by the positioning cone on the pressure plate returns it to its initial position without manual intervention, greatly improving production efficiency and reducing the scrap rate. Furthermore, during the reaming process, the system can, through the coordination of a pressure switch and a solenoid valve, avoid obstructing the normal operation of the reaming drill bit, ensuring the smooth progress of the reaming operation.

[0030] 3. A motorcycle clutch pressure plate reaming device, wherein the vent holes with different angles are densely distributed on the conical surface of the positioning cone. When the air pump is charging, the reaming debris falling on the equipment parts can be blown away, keeping the equipment clean, reducing the impact of debris on the operation of the equipment and the reaming accuracy, extending the service life of the equipment, and reducing the maintenance cost of the equipment.

[0031] 4. A motorcycle clutch pressure plate reaming device, comprising a displacement acquisition module and a torque resistance acquisition module that monitor the axial displacement of the positioning cone and the motor output torque in real time. The control module generates an evaluation coefficient by calculating and comprehensively analyzing the displacement fluctuation coefficient and the torque fluctuation coefficient, thereby determining whether the actuator needs to correct the pressure plate. This real-time monitoring and intelligent control method can promptly detect potential problems during the reaming process and take corresponding measures to adjust them, ensuring the stability and consistency of the reaming quality.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] Reference Figures 1-5 A motorcycle clutch pressure plate enlarging device includes a base plate 1 and a mounting platform 4. Multiple telescopic legs 2 are fixed at the top corners of the base plate 1. A pair of electric push rods 3 are fixed at the top of the base plate 1. The free ends of the telescopic legs 2 and the electric push rods 3 are respectively fixedly connected to the mounting platform 4. The inner walls on both sides of the mounting platform 4 are respectively provided with slots 5. The device also includes an x-axis platform 6 above the mounting platform 4. A y-axis platform 7 is fixedly connected to the free end of the x-axis platform 6. A fixing frame 8 is fixedly connected to the free end of the y-axis platform 7. A motor 9 is fixedly connected to the fixing frame 8. An enlarging drill bit 10 is installed on the output shaft of the motor 9. An anti-displacement mechanism is provided on the mounting platform 4 to prevent the pressure plate from shifting in the x-axis during enlarging.

[0041] In use, the pressure plate is placed between the two slots 5, positioning it in the middle of the mounting platform 4. This prevents the pressure plate from moving in the y and z directions through the slots 5. Then, the anti-offset mechanism is inserted into two of the circular holes on the pressure plate to restrict the pressure plate from moving along the length direction of the mounting platform 4, i.e., the x direction. This allows for quick fixation of the pressure plate. After fixation, the x-axis platform 6 and y-axis platform 7 drive the reaming drill bit 10 to move above the corresponding circular hole. Then, the motor 9 starts and drives the reaming drill bit 10 to rotate. Then, the electric actuator 3 starts and drives the mounting platform 4 and the pressure plate to move upward. In this way, the reaming drill bit 10 enters the corresponding circular hole to ream the hole.

[0042] The anti-deviation mechanism includes a pair of sliders 11, a pair of guide posts 12 are fixedly connected to the top of the sliders 11, a positioning cone 14 that can be inserted into the round hole on the pressure plate is slidably connected between the two guide posts 12, and a spring 13 is sleeved on the guide post 12. The two ends of the spring 13 are fixedly connected to the sliders 11 and the positioning cone 14 respectively.

[0043] In use, adjust the pressure plate so that the two round holes on the pressure plate are aligned with the two positioning cones 14 respectively. Then release the positioning cones 14. Under the action of the spring 13, the positioning cones 14 are driven to move upward and insert into the corresponding round holes, and press against the pressure plate. In this way, the two positioning cones 14 can restrict the movement of the pressure plate along the x direction. During the process of the round hole into which the positioning cones 14 are inserted being enlarged, the top of the positioning cones 14 will contact the reaming drill bit 10 and be subjected to downward pressure. The spring 13 will be compressed, and the positioning cones 14 will move downward to avoid the reaming drill bit 10, so that the reaming drill bit 10 can continue to enlarge the hole downward. After the enlargement is completed, the reaming drill bit 10 leaves the round hole, and the positioning cones 14 will be inserted into the round hole again under the elastic force of the spring 13 and press against the pressure plate again with their conical surface.

[0044] Furthermore, a slide rail 15 is fixedly connected below the mounting platform 4, and the slider 11 is slidably connected to the slide rail 15. A bidirectional screw 16 is rotatably connected inside the slide rail 15 and forms a threaded connection with the slider 11.

[0045] In use, rotate the bidirectional screw 16, and then use the bidirectional screw 16 to drive the two sliders 11 to move closer or further apart, thereby adjusting the distance between the two positioning cones 14, so as to adapt to different types of clutch pressure plates.

[0046] In addition, a motorcycle clutch pressure plate enlarging device also includes an actuator. The actuator includes an air pump 18 fixedly connected to a slide rail 15. The air pump 18 has a three-way valve 19 connected to its outlet. The two outlets of the three-way valve 19 are respectively connected to hoses 20. The positioning cone 14 is a hollow structure, and the conical surface is provided with a dense array of exhaust holes 17 at different angles. The hoses 20 are connected to the air inlet pipe at the bottom of the positioning cone 14. A pressure switch is embedded at the top of the positioning cone 14. Solenoid valves are installed in the two outlets of the three-way valve 19 respectively. The pressure switch is connected in series with the corresponding solenoid valve.

[0047] During use, if the pressure plate shifts during the reaming process, air can be pumped into the positioning cone 14 by the air pump 18. The positioning cone 14 will move upward due to the strong thrust of the airflow. The force generated by the cone surface on the circular hole will drive the pressure plate back to its initial position, achieving the effect of correction. When the circular hole inserted into the positioning cone 14 is reamed and then shifts, the corresponding solenoid valve will be closed because the reaming drill bit 10 is pressed on the pressure switch at the top of one of the positioning cones 14. In this way, the positioning cone 14 will not be filled with air, so it will not obstruct the reaming of the reaming drill bit 10. The other positioning cone 14 remains filled with air, and the pressure plate can be reset by the cooperation of the other positioning cone 14 and the reaming drill bit 10 inserted into the circular hole. In addition, the airflow from the exhaust hole 17 at different angles will blow away the debris generated by the reaming on the equipment parts, keeping the equipment clean.

[0048] In another embodiment, a motorcycle clutch pressure plate enlarging device further includes:

[0049] The displacement acquisition module 21 is installed on the slider 11 and connected to the positioning cone 14. It is used to monitor the axial displacement of the positioning cone 14 in real time and generate the displacement fluctuation coefficient through the control module 23.

[0050] The torque resistance acquisition module 22 is installed on the output shaft of the motor 9 to monitor the output torque of the motor 9 in real time and generate the torque fluctuation coefficient through the control module 23.

[0051] It should be noted that the displacement acquisition module 21 can be a displacement sensor or other device that can monitor the axial displacement of the positioning cone 14 in real time, the torque resistance acquisition module 22 can be a torque sensor or other device that can monitor the output torque of the motor 9 in real time, and the control module 23 is an embedded controller (such as the STM32 series) that integrates data fusion algorithms. Therefore, the displacement acquisition module 21, the torque resistance acquisition module 22 and the control module 23 are not specifically limited here and can be selected according to actual needs.

[0052] In use, the control module performs a comprehensive analysis of the generated displacement fluctuation coefficient and torque fluctuation coefficient, generates an evaluation coefficient, determines whether the actuator needs to correct the pressure plate, compares the evaluation coefficient with the pre-set evaluation coefficient reference threshold, and controls the working state of the actuator based on the comparison result.

[0053] The output and input terminals of the displacement acquisition module 21 and the output and input terminals of the torque and resistance acquisition module 22 are electrically connected to the input and output terminals of the control module 23, respectively. The output terminal of the control module 23 is electrically connected to the input terminal of the air pump 18.

[0054] The execution steps of the control module 23 in controlling the working state of the actuator based on the comparison results are as follows:

[0055] Real-time detection: Displacement acquisition module 21 acquires the axial displacement of positioning cone 14; Torque resistance acquisition module 22 acquires the output torque of motor 9;

[0056] Coefficient calculation:

[0057] Calculate the displacement fluctuation coefficient:

[0058] Among them, displacement fluctuation coefficient The degree of dispersion of the axial displacement of the positioning cone 14 within the circular hole of the pressure plate is quantified. The larger the value, the more violent the positioning cone 14 shakes, which reflects that the pressure plate has a horizontal offset in the groove (due to insufficient preload of spring 13), indicating that the actuator needs to intervene and correct the deviation. The smaller the value, the smoother the movement of the positioning cone 14, and the more reliably the pressure plate is fixed, indicating that no intervention or correction by the actuator is required.

[0059] The generation logic of the displacement fluctuation coefficient is as follows:

[0060] S1. The displacement acquisition module 21 acquires the actual axial displacement of the positioning cone 14 at different times within time T when the reaming drill bit 10 reams the pressure plate. The actual axial displacement acquired at time i within time T is calibrated as... , , It is a positive integer;

[0061] S2. Calculate the displacement fluctuation coefficient. The expression for the calculation is:

[0062]

[0063] In the formula, The average displacement over time T; The number of samples taken within time T.

[0064] Calculate the torque ripple coefficient:

[0065] Among them, torque ripple coefficient Characterizes the abnormal fluctuation of the resistance torque experienced by the reaming drill bit 10. The larger the value, the more severe the torque oscillation of the reaming drill bit, which reflects abnormal processing resistance (one-sided force caused by drill bit wear or pressure plate misalignment), indicating that the actuator needs to intervene and correct the deviation. The smaller the value, the more stable the torque output and the normal hole expansion process, indicating that no intervention or correction by the actuator is required.

[0066] The generation logic for the torque ripple coefficient is as follows:

[0067] S1. The torque resistance acquisition module 22 acquires the actual output torque of motor 9 at different times within time T when the reaming drill bit 10 is reaming the pressure plate. The actual output torque acquired at time j within time T is calibrated as... , , It is a positive integer;

[0068] S2. Calculate the torque fluctuation coefficient. The expression for the calculation is:

[0069]

[0070] In the formula, is the average torque over time T; m is the number of samples over time T.

[0071] Calculate evaluation coefficients Evaluation coefficient Fusion displacement fluctuation With torque fluctuation The coupling effect is a comprehensive indicator for assessing the risk of system instability. The higher the value, the greater the risk of system loss of control, requiring immediate and stronger corrective measures. The smaller the value, the more stable the system operation, maintaining the current state.

[0072] Among them, the formula analysis is performed by the control module 23, based on the formula:

[0073]

[0074] In the formula, α and β are preset weighting coefficients. .

[0075] Dynamic adjustment: If : Execution module in standby mode; if The execution module is activated, applying an additional upward thrust to the positioning cone 14. This is a reference threshold.

[0076] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
