Description

Technical Field

[0001] The present application relates to the technical field of torque detection tooling, and more particularly, to a vertical torque detection device. Background Art

[0002] A torque tester, also known as a torque meter, a torsion meter, or a torque gauge, is a precision instrument used to detect, test, and calibrate various torques. It is mainly used for the periodic calibration and detection of various torque-measuring rotating shafts, torque meters, and bottle cap tightening test instruments, and to determine whether the precision indicators of the test instruments meet the requirements. The detection and calibration are completed by using special fixtures, clamps, and other tools.

[0003] Currently, there are various torque detection devices on the market, and most of them are devices using weights, horizontal, and lever-type structures. Since these existing detection devices are relatively large in volume, complex in structure, and heavy in weight, they will occupy a large amount of space and are complex to operate. Moreover, the volume of small-range or small sensors is relatively small, so there are defects in inconvenient operation when detecting small-range or small sensors. Utility Model Content

[0004] The purpose of the present application is to provide a vertical torque detection device, aiming to solve the defect of inconvenient operation in detecting small-range or small sensors in the related art.

[0005] The additional aspects and advantages of the present application will be partly described below, and partly will become apparent from the description, or can be learned through the practice of the present application.

[0023] A slider, located at the movable end of the connecting rod, slides in a direction parallel to the length of the pressure rod;

[0024] The elastic member is fixedly connected between the sliding block and the movable end of the connecting rod.

[0025] In an exemplary embodiment of the present application, the adjustment assembly further includes a knob, a threaded rod, and a threaded sleeve;

[0026] The knob is rotatably arranged at an end of the slider away from the elastic member;

[0027] One of the threaded rod and the threaded sleeve is fixed at the center of the knob facing the slider, and the other is fixed at the end of the slider away from the elastic member; the threaded rod is threadedly connected to the threaded sleeve.

[0028] In an exemplary embodiment of the present application, it further includes: a workbench and a lifting mechanism;

[0029] The output shaft is rotatably connected to the upper surface of the workbench, the torque detection mechanism is located above the workbench and suspended directly above the output shaft, and the torque transmission mechanism is located inside the workbench and placed directly below the output shaft;

[0039] The exemplary embodiments of the present application may have the following partial or all beneficial effects:

[0040] 1. In a vertical torque detection device provided by the exemplary embodiment of the present application, first, the object to be measured is placed above the output shaft, and then the height of the torque detection mechanism is adjusted through the lifting mechanism so that the torque detection mechanism abuts against the object to be measured. Then, the operator provides torque to the output shaft through the torque transmission mechanism, so that the output shaft drives the object to be measured to rotate together. During the rotation process, the torque detection mechanism can detect the torque value of the object to be measured in the current rotation state. Through the above structure, the torque detection device not only has the advantages of simple structure, light weight and small occupied space, but also has the advantage of simple and convenient operation, thus providing convenience for the operator to operate when detecting small-range or small sensors.

[0041] 2. In a vertical torque detection device provided by the exemplary embodiment of the present application, by rotating the knob, the slider moves away from the connecting rod. The slider drives the connecting rod to rotate through the elastic member. When the connecting rod rotates towards the pressing rod, it can drive the pressing rod and the friction plate to move towards the friction wheel. Continuing to rotate the knob, the elastic member is stretched to increase the pulling force on the connecting rod, thereby increasing the pressure of the connecting rod on the pressing rod, and further increasing the friction force between the friction plate and the friction wheel. Conversely, moving the slider towards the connecting rod can reduce the friction force between the friction plate and the friction wheel. By increasing or decreasing the friction force, the resistance of the operator when turning the handwheel can be adjusted; on the one hand, when the object to be measured needs to be rotated slightly to detect the torque, the knob can be rotated to increase the resistance of turning the handwheel, avoiding the operator turning the handwheel too much and causing damage to the object to be measured; when the object to be measured needs to be twisted greatly for detection, the resistance of rotating the handwheel can be reduced. On the other hand, the stability of the torque output by the operator can also be improved through this method.

[0042] 3. In a vertical torque detection device provided by the exemplary embodiment of the present application, the distance between the output shaft and the torque detection mechanism can be adjusted through the lifting mechanism, so that the device can be applied to detect objects to be measured with different heights, improving the applicability of the device.

[0055] As Figure 1 shown, in an embodiment of the present application, a vertical torque detection device is provided, including:

[0056] An output shaft 1 for carrying the object to be measured and driving the object to be measured to rotate;

[0057] A torque detection mechanism 2 disposed above the output shaft 1, the torque detection mechanism 2 being in contact with the object to be measured for detecting the torque when the object to be measured rotates;

[0058] A torque transmission mechanism 3 for providing torque to the output shaft 1 to cause the output shaft 1 to perform a rotational motion with its own center as the rotation center;

[0059] The lifting mechanism 4 is located between the output shaft 1 and the torque detection mechanism 2 and is used to adjust the distance between the torque detection mechanism 2 and the output shaft 1.

[0060] In the embodiment of the present application, the torque detection mechanism 2 includes a torque sensor, which is used to accurately measure the torque value of the object to be measured. The specific operation process is as follows: First, the staff places the object to be measured on the output shaft 1, and then uses a special tooling to tightly fix the output shaft 1 and the object to be measured to ensure the stability and accuracy during the measurement process. Next, the position of the torque sensor is adjusted by the lifting mechanism 4 to gradually lower its position until its lower surface fits with the upper surface of the object to be measured, forming a stable contact surface. At this time, the staff can rotate the output shaft 1 by means of the torque transmission mechanism 3 to rotate the object to be measured to a preset angle under control. During this process, the torque detection mechanism 2 will monitor and record the torque value of the object to be measured when it rotates to a specific angle in real time, thus completing the detection task. This structure not only ensures that the torque detection device has a simple structure, light weight, and small space occupation, but also greatly simplifies the operation process, improves the convenience and efficiency of use. Furthermore, it provides convenience for the operator to operate when detecting small-range or small sensors.

[0061] In the embodiment of the present application, in order to further optimize the structure of the vertical torque detection device, the vertical torque detection device further includes a workbench 6, which serves as the base of the entire detection device. The output shaft 1 is arranged vertically and is rotationally connected to the workbench 6. The top of the output shaft 1 extends from the upper surface of the workbench 6, and its bottom is located inside the workbench 6, which not only saves space but also ensures the compactness and stability of the structure. In addition, the lifting mechanism 4 is installed on the upper surface of the workbench 6. Through the lifting mechanism 4, not only a stable support is provided for the torque detection mechanism 2, but also a height adjustment function is provided for adjusting the torque detection mechanism 2, enabling the torque detection mechanism 2 to be suspended directly above the output shaft 1, ensuring the accurate alignment between the torque sensor and the object to be measured during the detection process, and thus improving the accuracy and reliability of the detection.

[0062] As Figure 2As shown, in the embodiment of the present application, the torque transmission mechanism 3 includes a speed reducer 31, which realizes the effective transmission and enhancement of torque. Specifically, the speed reducer 31 is provided with a torque input end and a torque output end. Among them, the torque input end is connected to a power source suitable for providing torque, ensuring the input of controllable torque. The rotational power provided by the power source is input into the speed reducer 31 through the torque input end. After the speed reducer 31 amplifies the torque, the torque is enhanced. It should be noted that the center of the torque output end should be aligned with the center of the output shaft 1 on the same axis, and the two are fixedly connected to each other. Through this structure, it is ensured that the torque transmitted from the torque output end to the output shaft 1 is not only accurate but also can smoothly drive the output shaft 1 to rotate, thereby realizing the precise control and detection of the object to be measured.

[0063] In the embodiment of the present application, there is no special limitation on the specific structural design of the power source and the speed reducer 31. The power source can be either equipment-driven, using automation equipment such as motors to provide stable power, or manually driven, realizing the input of power through manual operation to meet the requirements in different scenarios.

[0064] In the preferred embodiment of the present application, the structure of the speed reducer 31 can either adopt the method of multiple gears meshing with each other to form a gear set to realize the efficient transmission and adjustment of torque, or adopt the meshing method of worm and worm gear to realize the precise control of torque. In the present application, it is preferably to use manual drive as the power source, combined with the speed reducer 31 composed of a worm and a worm gear, with the worm as the torque input end and the worm gear as the torque output end. This design not only ensures the stability and controllability of power transmission but also makes full use of the self-locking characteristic of worm and worm gear transmission to improve the accuracy and reliability of torque detection. In addition, the output shaft 1 is fixedly connected to the worm gear along the rotation axis of the worm gear, ensuring the directness and efficiency of power transmission and further improving the performance and practicality of the entire vertical torque detection device.

[0065] As Figure 1 and Figure 2 shown, when the power source adopts manual drive, for this reason, the torque transmission mechanism 3 further includes a handwheel 32 and a wheel shaft 33. The wheel shaft 33 is arranged along the axis direction of the worm and is fixedly connected to the end of one end of the worm, ensuring the directness and efficiency of power transmission. The handwheel 32 is fixedly connected to the other end of the wheel shaft 33, providing convenience for the operation of the staff. During torque detection, the staff only needs to easily rotate the handwheel 32. The rotation of the wheel shaft 33 drives the worm to rotate, and the worm meshes with the worm gear to drive the worm gear to rotate. The rotation of the worm gear further drives the output shaft 1 to rotate, realizing the precise transmission of torque and ensuring the accuracy and reliability of the detection result.

[0066] In the embodiments of the present application, in order to achieve a dual optimization of space utilization and operation convenience, the torque input end is arranged in the horizontal direction, and the torque output end is arranged in the vertical direction. Specifically, the torque input end is perpendicular to the side wall of the workbench 6, enabling the staff to easily adjust the torque input in the horizontal direction, improving the convenience and efficiency of the staff's operation. At the same time, the torque output end is arranged in the vertical direction and is perpendicular to the top wall of the workbench 6, ensuring that the rotational power of the output shaft 1 can be directly and smoothly transmitted. This structure not only further optimizes the spatial structure of the detection device, making it more compact and reasonable, but also provides great convenience for the detection operation of the staff, ensuring the high efficiency and accuracy of the detection process.

[0067] In the embodiments of the present application, the vertical torque detection device further includes a resistance adjustment mechanism 5 for improving the operation stability and accuracy. Through the resistance adjustment mechanism 5, the staff will feel an appropriate resistance when turning the handwheel 32. The increase in this resistance can not only effectively control the rotation amplitude of the handwheel 32 but also achieve fine adjustment of the torque transmission process. It ensures the smoothness of torque transmission, avoids damage to the measured object caused by excessive operation amplitude resulting in torque, and thus provides a more stable and reliable environment for the detection process.

[0068] As Figure 2 and Figure 4 shown, in the embodiments of the present application, the resistance adjustment mechanism 5 includes a friction wheel 51, a friction plate 52, and an adjustment assembly 53.

[0069] Specifically, the friction wheel 51 can be placed at the torque input end, the torque output end, or even at both ends simultaneously. When the friction wheel 51 is located at the torque input end, it can be sleeved outside the wheel shaft 33 and fixedly connected to the wheel shaft 33, or sleeved outside the worm and fixedly connected to the worm; when the friction wheel 51 is placed at the torque output end, it is sleeved outside the output shaft 1 and fixedly connected to the output shaft 1, directly acting on the output shaft 1 to achieve precise control of the output torque. In the preferred embodiment of the present application, the friction wheel 51 is preferably arranged at the torque output end, located below the workbench 6 and directly below the worm gear, and the output shaft 1 passes through the worm gear and is fixedly connected to the friction wheel 51.

[0070] Furthermore, the friction plate 52 is located on one side of the friction wheel 51 and can move along the direction of approaching or separating from the friction wheel 51. The friction plate 52 is set to an inwardly concave arc shape on the side facing the friction wheel 51 to increase the contact area between the two. The friction plate 52 is provided with a wheel groove on the side facing the friction wheel 51, and a friction belt 521 is fixedly arranged in the wheel groove of the friction plate 52. The friction belt 521 can increase the friction force between the friction plate 52 and the friction wheel 51.

[0071] Furthermore, the adjustment component 53 can adjust the position of the friction plate 52, and increase or decrease the pressure of the friction plate 52 on the friction wheel 51 after the friction plate 52 contacts the friction wheel 51. Therefore, when the friction plate 52 contacts the friction wheel 51, the pressure of the friction plate 52 on the friction wheel 51 can be accurately increased or decreased. As for the specific structure of the adjustment component 53, the embodiment of the present application does not impose any special restrictions.

[0072] In the embodiment of the present application, it is intended to achieve precise control and optimization of the resistance adjustment mechanism 5 of the vertical torque detection device. The adjustment component 53 includes a pressure rod 531, a connecting rod 532, a slider 533 and an elastic member 534. The pressure rod 531 is fixedly connected to the side of the friction plate 52 away from the friction wheel 51. In the present application, the friction plate 52 and the pressure rod 531 are an integrated structure, so that the pressure rod 531 can move together with the friction plate 52; one end of the connecting rod 532 is set as a fixed end, and the other end of the connecting rod 532 is set as a movable end. The fixed end of the connecting rod 532 is rotatably connected to the bottom wall of the workbench 6, and the movable end is not connected to the workbench 6, so that the connecting rod 532 can perform a circular motion with the fixed end as the center and its own length as the radius. The pressure rod 531 is located on one side of the connecting rod 532 and can abut against the side wall of the connecting rod 532, ensuring the directness and efficiency of power transmission.

[0073] The slider 533 and the pressure rod 531 are located on the same side of the connecting rod 532, and the slider 533 slides in a direction parallel to the pressure rod 531. A fixed sleeve is provided on the outer sleeve of the slider 533, and the fixed sleeve is fixedly connected to the bottom wall of the workbench 6, which not only provides precise guiding effect for the moving direction of the slider 533, but also ensures the stability of the slider 533 during the movement process, and avoids the influence of shaking during the sliding process on the change of resistance.

[0074] The elastic member 534 is connected between the slider 533 and the movable end of the connecting rod 532. In the embodiment of the present application, its elastic characteristics can ensure that the friction plate 52 can change its pressure on the friction wheel 51 after contacting the friction wheel 51, and at the same time provide a buffer effect for the resistance adjustment process, thereby improving safety. The elastic member 534 is preferably a tension spring, but of course the selection of the elastic member 534 is not limited to the tension spring, and other elements with similar elastic characteristics are also applicable to the structure of the present application.

[0075] When the staff operates the slider 533 and slides it in the direction away from the connecting rod 532, the movement of the slider 533 drives the elastic member 534 to deform. At this time, the elastic member 534 exerts a certain force on the movable end of the connecting rod 532 with its own elastic characteristics, prompting the connecting rod 532 to rotate in the direction of the pressure rod 531. As the slider 533 continues to move in this direction, the force exerted by the connecting rod 532 on the pressure rod 531 gradually increases, and then the pressure rod 531 pushes the friction plate 52 into contact with the friction wheel 51 and applies pressure.

[0076] Conversely, when the staff moves the slider 533 in the direction of the connecting rod 532, this operation reduces the friction between the friction plate 52 and the friction wheel 51. As the slider 533 moves in the reverse direction, the degree of deformation of the elastic member 534 decreases, the force exerted by the connecting rod 532 on the pressure rod 531 weakens accordingly, and the squeezing force of the friction plate 52 on the friction wheel 51 decreases, thereby reducing the friction between the friction plate 52 and the friction wheel 51. This process effectively realizes the adjustment of the pressure between the friction plate 52 and the friction wheel 51 to adjust the resistance of the rotating handwheel 32.

[0077] Furthermore, the following is an optimized solution aimed at achieving the convenient movement and precise positioning of the slider 533 to ensure the stability and accuracy of the torque detection process. The adjustment assembly 53 further includes a knob 535, a threaded rod 536, and a threaded sleeve 537.

[0078] The knob 535 is rotatably connected to the side wall of the workbench 6, ensuring that it can rotate freely and providing a convenient operation method for the staff. The threaded sleeve 537 is threadedly connected to the threaded rod 536. The threaded rod 536 is fixedly connected to the center of the side of the knob 535 facing the slider 533. The threaded sleeve 537 is fixedly arranged inside the slider 533 along the sliding direction of the slider 533, and the opening of the threaded sleeve 537 faces the knob 535. In this application, the slider 533 and the threaded sleeve 537 are an integral structure. Therefore, it can be considered that a threaded hole is provided inside the slider 533. When the staff needs to adjust the resistance of the handwheel 32 to rotate, simply rotating the knob 535 can be converted into the axial movement of the threaded rod 536. The threaded rod 536 is retracted or extended into the threaded sleeve 537, and then drives the slider 533 to move along a predetermined direction, realizing the precise adjustment of the friction between the friction plate 52 and the friction wheel 51. This structure not only simplifies the operation process, improves the adjustment efficiency, but also ensures the stability and positioning accuracy of the slider 533 during movement, enabling the torque to be stably and reliably output during the torque detection process.

[0079] Of course, the structure of the adjustment component 53 is not limited to the above solution. In the embodiment of the present application, an alternative solution is also provided, that is, the threaded sleeve 537 is fixedly connected to the knob 535, and the threaded rod 536 is fixedly connected to the slider 533. This design can also achieve the precise movement and positioning of the slider 533.

[0080] In the embodiment of the present application, the lifting mechanism 4 includes a fixed frame 41, a lead screw 42, a lead nut 43, and a support frame 44. It enables the torque detection mechanism 2 to move stably in the vertical direction, so that the torque detection device can be applied to more different sizes of objects to be measured, improving the applicability of the device.

[0081] The fixed frame 41 is arranged in the vertical direction, and its bottom is fixedly connected to the upper surface of the workbench 6, ensuring the stability and reliability of the entire lifting mechanism 4. The fixed frame 41 is provided with a guide groove 411 along its length direction on the side facing the torque detection mechanism 2, providing a precise guiding effect for the movement of the support frame 44. The lead screw 42 is arranged in the vertical direction inside the fixed frame 41, and its bottom is rotatably connected to the upper surface of the workbench 6. The top of the lead screw 42 is fixedly connected with a rotating wheel 421, facilitating the staff to rotate the lead screw 42.

[0082] The lead nut 43 is sleeved on the lead screw 42 and is threadedly connected to the lead screw 42, enabling the lead screw 42 to drive the lead nut 43 to move in the vertical direction when rotating. The torque detection mechanism 2 is installed on the support frame 44. One end of the support frame 44 extends into the fixed frame 41 from the guide groove 411 and is fixedly connected to the lead nut 43, ensuring that the lead nut 43 can drive the support frame 44 and the torque detection mechanism 2 to move synchronously when moving. The support frame 44 is in close contact with the inner walls on both sides of the guide groove 411 at the guide groove 411, providing good stability for the support frame 44 during movement and avoiding affecting the accuracy of torque detection due to rotation.

[0083] When the staff needs to adjust the height of the torque detection mechanism 2, they only need to simply rotate the rotating wheel 421, which can be converted into the rotation of the lead screw 42. During the rotation of the lead screw 42, through the threaded connection with the lead nut 43, it drives the support frame 44 and the torque detection mechanism 2 to move up and down in the vertical direction, realizing the adjustment of the height of the torque detection mechanism 2.

[0084] As Figure 1 and Figure 5 shown, in the embodiment of the present application, the vertical torque detection device further includes a connecting plate 8. The connecting plate 8 is located between the support frame 44 and the torque detection mechanism 2. One end of the connecting plate 8 is fixedly connected to the support frame 44, and the torque detection mechanism 2 is installed at the other end of the connecting plate 8, making the center of the torque sensor and the center of the output shaft 1 on the same axis.

[0085] Refer toFigure 6 Furthermore, to facilitate detecting whether the center of the torque sensor is aligned with the center of the output shaft 1, the vertical torque detection device in the embodiment of the present application further includes a concentricity calibration shaft 7. The bottom of the concentricity calibration shaft 7 is configured in a conical shape, and the top of the concentricity calibration shaft 7 can be accurately inserted vertically below the torque sensor, providing a stable and reliable reference for the calibration process.

[0086] A distinct mark, such as a marked point or a conical hole, is preset at the center of the output shaft 1, providing an intuitive reference point for the calibration process. When calibrating whether the center of the torque sensor is aligned with the center of the output shaft 1, the staff only needs to drive the torque detection mechanism 2 to descend through the lifting mechanism 4 so that the bottom of the concentricity calibration shaft 7 is aligned with the marked position at the center of the output shaft 1. If the bottom of the concentricity calibration shaft 7 is exactly located at the marked position at the center of the output shaft 1, that is, the center of the marked point or the conical hole, it indicates that the center of the torque sensor is precisely aligned with the center of the output shaft 1. Conversely, if there is a deviation between the bottom of the concentricity calibration shaft 7 and the marked position, it means that the centers of the two have not reached the aligned state and need to be further adjusted until they are aligned.

[0087] Refer to Figure 1 and Figure 5 Furthermore, to enable easy adjustment of the position of the torque sensor, a first elongated hole 81 is formed through one end of the connecting plate 8 close to the support frame 44, and a second elongated hole 441 is formed through the support frame 44. The length direction of the first elongated hole 81 is parallel to the length direction of the connecting plate 8, while the length direction of the second elongated hole 441 is perpendicular to the length direction of the first elongated hole 81 in the horizontal direction. This structure enables relative movement between the connecting plate 8 and the support frame 44.

[0088] By passing a fastening bolt through the first elongated hole 81 and the second elongated hole 441 and then threadedly connecting it with a fastening nut, the connection and fixation between the connecting plate 8 and the support frame 44 are achieved. When the bottom of the concentricity calibration shaft 7 is not at the marked position at the center of the output shaft 1, the staff can first loosen the fastening nut, move the connecting plate 8 until the bottom of the concentricity calibration shaft 7 is precisely located at the marked position at the center of the output shaft 1, that is, the center of the marked point or the conical hole, and then tighten the fastening nut to firmly fix the connecting plate 8 and the support frame 44. This structure not only ensures the precise alignment between the torque sensor and the output shaft 1 but also provides a convenient adjustment method for the staff, greatly improving the flexibility and convenience of the operation.

[0089] Furthermore, to ensure the firmness between the torque sensor and the connecting plate 8, in the embodiment of the present application, the torque detection mechanism 2 includes, in addition to the torque sensor, a locking structure 9 for connecting and fixing the torque sensor and the connecting plate 8.

[0090] In the embodiment of the present application, the locking structure 9 adopted is the locking structure 9 of a hydraulic expander. The ETP locking structure 9 includes a fixing plate, an ETP bushing, an ETP gland, an ETP, and a sensor flange. The torque sensor is fixedly connected to the ETP through the sensor flange, ensuring a tight fit between the sensor and the ETP. Through the ETP tensioning and precise fit with the fixing plate, the ETP bushing, and the ETP gland, a firm locking structure 9 is formed, which not only realizes the stable installation and fixation between the torque sensor and the connecting plate 8, but also ensures the stability and reliability of the device during operation.

[0091] In addition, the ETP locking structure 9 also takes into account the use requirements of the concentricity calibration shaft 7. After inserting the concentricity calibration shaft 7 from the bottom of the torque sensor, the ETP locking structure 9 can achieve the locking and fixation of the concentricity calibration shaft 7 and the torque sensor, providing convenience for the calibration work of the staff.
