Description

Technical Field

[0001] This utility model relates to the field of clutch production and testing technology, and in particular to a clutch separation testing device. Background Technology

[0002] Currently, as a key component in the transmission system, the clutch's disengagement performance directly affects the operational stability and safety of the equipment. During the production and maintenance of clutches, it is necessary to use testing devices to simulate actual working conditions and check whether the disengagement status meets the standards.

[0003] Existing clutch disengagement testing devices mostly use toothed synchronous belt drives to achieve power transmission between the motor and the clutch. However, in long-term use, the toothed synchronous belt is prone to wear and stretching, resulting in a decrease in tension, slippage, and tooth skipping, which in turn affects the transmission accuracy and the accuracy of the test results. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a clutch disengagement detection device.

[0005] This utility model is achieved using the following technical solution: a clutch separation detection device, comprising a detection frame, a clutch body on the top of the detection frame, a rotating assembly capable of driving the clutch body to rotate on one side of the clutch body, a first drive gear fixedly mounted on one end of the rotating assembly, a stepper motor on one side of the detection frame, a second drive gear fixedly mounted on the output shaft of the stepper motor, a toothed synchronous belt for synchronous transmission fitted on the first drive gear and the second drive gear, an adjustment assembly capable of adjusting the tension of the toothed synchronous belt on one side of the toothed synchronous belt, a fixing assembly capable of fixing the adjusted position of the adjustment assembly on one end of the adjustment assembly, the adjustment assembly comprising a sliding strip fixedly mounted on the detection frame, a sliding groove on one side of the sliding strip, a sliding block slidably disposed inside the sliding groove, a concave mounting block fixedly mounted on one side of the sliding block, a rotating column rotatably mounted inside the mounting block, and an adjustment gear rotatably mounted on the rotating column.

[0006] Through the above technical solution, the stepper motor can drive the rotating component to drive the clutch body to rotate through the cooperation of the second drive gear, the toothed synchronous belt and the first drive gear, simulating the actual operating conditions to achieve separation detection; at the same time, the sliding block in the adjusting component can move along the sliding groove, driving the mounting block, rotating column and adjusting gear to move synchronously. By adjusting the position of the gear, the tension of the toothed synchronous belt is changed, solving the problem of tension drop. The fixing component can further lock the position of the adjusting component to ensure tension stability and improve transmission accuracy and detection accuracy.

[0007] As a further improvement to the above solution, one side of the adjusting gear meshes with the inner surface of the toothed synchronous belt, and limiting plates for restricting the movement of the toothed synchronous belt are fixedly installed on both sides of the first driving gear, the second driving gear, and the adjusting gear.

[0008] By adjusting the meshing between the gear and the inner surface of the toothed synchronous belt, a force can be directly applied to the toothed synchronous belt during movement, and the tension can be precisely adjusted; while the limiting plate can restrict the toothed synchronous belt from shifting along the gear axis during transmission, preventing the toothed synchronous belt from disengaging from the gear and ensuring transmission stability.

[0009] As a further improvement to the above solution, both the sliding groove and the sliding block are arranged in a "T" shape.

[0010] Through the above technical solution, the "T"-shaped structure can prevent the sliding block from falling out of the sliding groove when it slides in the sliding groove, ensuring the stability of the sliding block's movement process, and thus ensuring the smoothness of the adjustment gear's adjustment of the toothed synchronous belt tension.

[0011] As a further improvement to the above solution, the sliding groove is provided with a threaded rod inside, the sliding block is threadedly sleeved on the threaded rod, one end of the threaded rod is rotatably installed with the inner wall of the sliding groove, and the other end of the threaded rod passes through the sliding strip and the detection frame in sequence and is fixedly installed with a handwheel.

[0012] With the above technical solution, the operator can turn the handwheel to drive the threaded rod to rotate. By utilizing the threaded engagement between the threaded rod and the sliding block, the rotational motion of the threaded rod is converted into the linear motion of the sliding block, thereby achieving precise adjustment of the sliding block position. This allows for precise control of the adjustment range of the adjusting gear on the tension of the toothed synchronous belt, making the operation convenient and the adjustment accuracy high.

[0013] As a further improvement to the above solution, the sliding groove is provided with a cylindrical limiting ring inside. The limiting ring is fixedly sleeved on the threaded rod, and one side of the limiting ring is in contact with the inner wall of the sliding groove.

[0014] Through the above technical solution, the limiting ring can restrict the threaded rod from moving along its own axis during rotation, ensuring that the threaded rod always maintains a fixed axial position and rotates stably, avoiding deviation of the sliding block's movement trajectory due to threaded rod offset, and ensuring the reliability of the adjustment component's operation.

[0015] As a further improvement to the above solution, the fixing component includes a ratchet fixedly sleeved on one end of the threaded rod passing through the detection frame. A rotating block with a torsion spring inside is provided on one side of the ratchet. The rotating block is installed on one side of the detection frame. A locking block is fixedly installed on the cylindrical surface of the rotating block. The locking block is arc-shaped, and one end of the locking block is constricted. The constricted end of the locking block extends into the groove of the ratchet.

[0016] Through the above technical solution, the torsion spring inside the rotating block can push the locking block, so that the contracted end of the locking block is locked into the groove of the ratchet, restricting the ratchet from rotating in the opposite direction, thereby locking the position of the threaded rod and preventing the sliding block from moving due to the reaction force of the toothed synchronous belt.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by setting up an adjustment component and a fixing component, allows the threaded rod to rotate via a handwheel, which in turn moves the sliding block and the adjustment gear to precisely adjust the tension of the toothed synchronous belt. The ratchet and locking block of the fixing component then lock the adjustment position, effectively solving the problems of easy decrease in the tension of the toothed synchronous belt and unstable position after adjustment in existing devices.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figures 1-3This embodiment of a clutch disengagement detection device includes a detection frame 1. A clutch body 2 is provided on the top of the detection frame 1. A rotating component 3 capable of driving the clutch body 2 to rotate is provided on one side of the clutch body 2. A first drive gear 4 is fixedly installed at one end of the rotating component 3. A stepper motor 5 is provided on one side of the detection frame 1. A second drive gear 6 is fixedly installed on the output shaft of the stepper motor 5. A toothed synchronous belt 7 for synchronous transmission is sleeved on the first drive gear 4 and the second drive gear 6. An adjustment component capable of adjusting the tension of the toothed synchronous belt 7 is provided on one side of the toothed synchronous belt 7. A fixing component capable of fixing the adjusted position of the adjustment component is provided at one end of the adjustment component.

[0026] The adjustment assembly includes a sliding bar 801 fixedly installed on the detection frame 1. A sliding groove 802 is provided on one side of the sliding bar 801. A sliding block 803 is slidably arranged inside the sliding groove 802. A concave mounting block 804 is fixedly installed on one side of the sliding block 803. A rotating column 805 is rotatably installed inside the mounting block 804. An adjustment gear 806 is rotatably installed on the rotating column 805.

[0027] The stepper motor 5 can drive the rotating assembly to drive the clutch body 2 to rotate through the cooperation of the second drive gear 6, the toothed synchronous belt 7 and the first drive gear 4, simulating the actual operating conditions to achieve separation detection; at the same time, the sliding block 803 in the adjusting assembly can move along the sliding groove 802, driving the mounting block 804, the rotating column 805 and the adjusting gear 806 to move synchronously. By adjusting the position of the gear 806, the tension of the toothed synchronous belt 7 is changed, solving the problem of tension drop. The fixing assembly can further lock the position of the adjusting assembly to ensure tension stability and improve transmission accuracy and detection accuracy.

[0028] One side of the adjusting gear 806 meshes with the inner surface of the toothed synchronous belt 7. Limiting plates for restricting the movement of the toothed synchronous belt 7 are fixedly installed on both sides of the first drive gear 4, the second drive gear 6, and the adjusting gear 806.

[0029] The adjusting gear 806 meshes with the inner surface of the toothed synchronous belt 7, allowing force to be applied directly to the toothed synchronous belt 7 during movement, thus precisely adjusting the tension; while the limiting piece can restrict the toothed synchronous belt 7 from shifting along the gear axis during transmission, preventing the toothed synchronous belt 7 from disengaging from the gear and ensuring transmission stability.

[0030] Both the sliding groove 802 and the sliding block 803 are arranged in a "T" shape.

[0031] The "T"-shaped structure prevents the sliding block 803 from detaching from the sliding groove 802 when it slides within the sliding groove 802, ensuring the stability of the sliding block 803's movement and thus guaranteeing the smoothness of the adjustment gear 806's adjustment of the tension of the toothed synchronous belt 7.

[0032] The sliding groove 802 is provided with a threaded rod 10 inside. The sliding block 803 is threadedly sleeved on the threaded rod 10. One end of the threaded rod 10 is rotatably installed with the inner wall of the sliding groove 802. The other end of the threaded rod 10 passes through the sliding strip 801 and the detection frame 1 in sequence and is fixedly installed with a handwheel 11.

[0033] The operator can rotate the handwheel 11 to drive the threaded rod 10 to rotate. By utilizing the threaded engagement between the threaded rod 10 and the sliding block 803, the rotational motion of the threaded rod 10 is converted into the linear motion of the sliding block 803, thereby achieving precise adjustment of the position of the sliding block 803. This allows for precise control of the adjustment range of the adjusting gear 806 on the tension of the toothed synchronous belt 7. The operation is convenient and the adjustment accuracy is high.

[0034] The sliding groove 802 is provided with a cylindrical limiting ring 12 inside. The limiting ring 12 is fixedly sleeved on the threaded rod 10, and one side of the limiting ring 12 is in contact with the inner wall of the sliding groove 802.

[0035] The limiting ring 12 can limit the threaded rod 10 from moving along its own axis during rotation, ensuring that the threaded rod 10 always maintains a fixed axial position and rotates stably, avoiding deviation of the sliding block 803's movement trajectory due to the offset of the threaded rod 10, and ensuring the reliability of the adjustment component's operation.

[0036] The fixing component includes a ratchet 901 fixedly sleeved on one end of the threaded rod 10 that passes through the detection frame 1. The groove of the ratchet 901 is inclined, so when the ratchet 901 rotates in the inclined direction, the locking block 903 cannot be locked into the groove. Only when the ratchet 901 rotates in the opposite direction will the inner wall of the groove abut against the locking block 903, preventing the ratchet 901 from rotating. A rotating block 902 with a torsion spring inside is provided on one side of the ratchet 901. The rotating block 902 is installed on one side of the detection frame 1. The locking block 903 is fixedly installed on the cylindrical surface of the rotating block 902. The locking block 903 is arc-shaped, and one end of the locking block 903 is constricted. The constricted end of the locking block 903 extends into the groove of the ratchet 901.

[0037] The torsion spring inside the rotating block 902 can push the locking block 903, causing the contracted end of the locking block 903 to engage in the slot of the ratchet 901, restricting the ratchet 901 from rotating in the opposite direction, thereby locking the position of the threaded rod 10 and preventing the sliding block 803 from moving due to the reaction force of the toothed synchronous belt 7.

[0038] The implementation principle of a clutch separation detection device in this embodiment is as follows: First, the stepper motor 5 is started, and the output shaft of the stepper motor 5 begins to rotate, driving the second drive gear 6 fixed on the output shaft to rotate synchronously. Since the second drive gear 6 is connected to the first drive gear 4 through the toothed synchronous belt 7, when the second drive gear 6 rotates, it will drive the first drive gear 4 to rotate through the toothed synchronous belt 7. The first drive gear 4 is fixed at one end of the rotating component 3, so the first drive gear 4 will drive the rotating component 3 to rotate, and the rotating component 3 will then drive the clutch body 2 to rotate, simulating the rotation state of the clutch when it is actually working, in preparation for subsequent separation detection.

[0039] If slippage or skipping of teeth is found in the toothed synchronous belt 7 during the inspection process, the handwheel 11 should be turned in one direction first. Since the groove of the ratchet 901 is inclined, when the handwheel 11 is turned in the inclined direction, the locking block 903 cannot stop the rotation of the ratchet 901. In this way, the handwheel 11 drives the threaded rod 10 to rotate in the sliding groove 802. The limiting ring 12 can prevent the threaded rod 10 from moving axially. Since the sliding block 803 is threaded on the threaded rod 10 and the sliding block 803 is engaged with the "T"-shaped sliding groove 802 and cannot rotate, the rotational motion of the threaded rod 10 is converted into the linear motion of the sliding block 803 along the sliding groove 802. When the sliding block 803 moves, it will drive the mounting block 804 on the side to move synchronously. 04 drives the internal rotating column 805 and the adjusting gear 806 on the rotating column 805 to move; since the adjusting gear 806 meshes with the inner surface of the toothed synchronous belt 7, the moving adjusting gear 806 will generate a tensile force on the toothed synchronous belt 7, thereby adjusting the tension of the toothed synchronous belt 7; when the tension of the toothed synchronous belt 7 is adjusted to a suitable level, without slippage or tooth skipping, stop rotating the handwheel 11, release the rotating block 902, and the rotating block 902 will be pressed tightly against the surface of the ratchet 901 under the elastic force of the internal torsion spring, driving the locking block 903 to re-lock into the slot of the ratchet 901, restricting the ratchet 901 from rotating in the opposite direction, thereby locking the position of the threaded rod 10, keeping the sliding block 803 and the adjusting gear 806 fixed, and ensuring the stability of the tension of the toothed synchronous belt 7.

[0040] After the tension of the toothed synchronous belt 7 stabilizes, the stepper motor 5 continues to run, so that the clutch body 2 rotates continuously and stably. The staff monitors the separation state of the clutch body 2 using special testing instruments, such as displacement sensors and torque sensors, and records key parameters such as separation stroke and separation torque to complete the clutch separation performance test. During the test, the limiting plates on both sides of the first drive gear 4, the second drive gear 6 and the adjusting gear 806 can prevent the toothed synchronous belt 7 from shifting axially, ensuring transmission stability and ensuring the accuracy of the test data.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
