Description
Technical Field
[0001] This utility model relates to torque measuring mechanisms, and more particularly to quick-release torque measuring mechanisms. Background Technology
[0002] With the widespread application of automated assembly technology, higher requirements have been placed on the assembly quality of connectors in mechanical equipment. Especially in industries with stringent requirements for connection and fastening precision, such as aerospace, automotive, and precision instruments, torque detection has become a crucial step in ensuring assembly reliability and safety. To improve detection efficiency and accuracy, more and more production lines are introducing automatically controllable torque detection mechanisms. These mechanisms are typically configured within assembly equipment to detect the torque values of connectors in real time, and combine this with a control system for data feedback and calibration control to ensure consistent quality throughout the connection process.
[0003] Most existing torque measurement mechanisms employ a fixed mounting structure, meaning the torque detection component is rigidly connected to the assembly platform. This type of structure typically includes a servo motor, reducer, drive shaft, and torque sensor, used to drive and detect the tightening process of the connectors. In some structures, to accommodate connectors of different shapes, they also mate with standard gauge joints via connecting flanges or guide structures.
[0004] However, existing structures generally lack effective buffering and alignment mechanisms, which can easily lead to accidental contact between the gauge connector and the end slot of the connector due to positional deviations during high-precision automatic insertion, causing damage to the connector or measuring structure. Therefore, there is an urgent need to propose a quick-release torque measuring mechanism to solve the above problems. Utility Model Content

[0033] Beneficial effects of the embodiments of this utility model
[0034] 1. Because this technical solution adopts a bidirectional moving structure including a floating cylinder and a lifting component, it improves the flexible alignment capability during the insertion process. Therefore, it effectively solves the problem of collision damage caused by position deviation of the gauge joint and the end slot of the connector during the automatic insertion process in the prior art. This enables automatic alignment, flexible buffering and component protection functions in the torque detection process, effectively improving the reliability and adaptability of the assembly and testing system.
[0035] 2. Because a position sensor is set on the torque detection component, and a first reflector and a second reflector are set on the moving plate, and the vertical distance between the first reflector and the second reflector is consistent with the depth of the connector end groove, the timing of the reflected signal received by the position sensor can accurately determine whether the moving end has moved to the preset insertion position. This effectively solves the problem in the prior art that the insertion depth of the go gauge connector cannot be detected in real time, which easily leads to incomplete insertion or over-insertion. Thus, it realizes the precise control of the automatic insertion position between the go gauge connector and the connector during the torque detection process, and improves the intelligence level of the detection operation and the stability of the insertion action.
[0036] 3. Since the connecting shaft is designed as a floating shaft, and the floating distance of the floating shaft is equal to the depth of the end groove of the connector, the floating shaft can provide progressive clearance space in the axial direction when the gauge joint and the end groove of the connector are threaded together during the torque testing process. This effectively solves the problems of meshing resistance, uneven torque loading, or connection damage caused by axial restriction during the threading process of the gauge joint in the prior art. Thus, it realizes adaptive progressive engagement during the threaded connection process, effectively improving the stability of torque application and the safety and accuracy of the testing process.

[0043] See Figures 1 to 2This application provides a preferred embodiment of a quick-release torque measuring mechanism for detecting the torque of a connector installed at a mounting position. It is suitable for automated assembly lines where high connection accuracy is required, such as in the assembly and inspection processes of aerospace components, automotive parts, and precision instruments. The connector includes an end slot. The torque measuring mechanism includes a lifting assembly 10, a floating cylinder 20, and a torque detection assembly 30. The lifting assembly 10 includes a controlled-moving lifting end; the floating cylinder 20 is connected to the lifting end and includes a controlled-moving movable end, the movement trajectory of which is parallel to the movement trajectory of the lifting end; the torque detection assembly 30 is connected to the floating cylinder 20 and includes a servo motor 310, a reducer 320, a connecting shaft 330, a quick-release flange 340, and a gauge joint 350. The servo motor 310 is connected to the movable end to move with it, and includes a first output end. 20 is connected to the servo motor 310. The reducer includes an input end and a second output end. The input end is connected to the first output end. The connecting shaft 330 is connected to the reducer 320. One end of the connecting shaft 330 is connected to the second output end. The connecting shaft 330 is a floating shaft. A quick-release flange 340 is provided at the other end of the connecting shaft 330. A go gauge connector 350 is detachably connected to the quick-release flange 340. The go gauge connector 350 is configured to connect to the end groove of the connector installed at the mounting position when the movable end moves to a preset stroke.
[0044] Specifically:
[0045] The torque measuring mechanism mainly includes a lifting assembly 10, a floating cylinder 20, and a torque detection assembly 30 connected thereto. The lifting assembly 10 is used to control the entire detection assembly to move up and down in the vertical direction. Its structure can be a servo lifting module, a pneumatic lifting mechanism, or other linear actuation unit. The lifting end is a controllable moving end and is connected to the floating cylinder 20.
[0046] The floating cylinder 20 is mounted on the lifting end, and its movable end can move in a direction parallel to the lifting direction, that is, it has a certain floating stroke in the vertical direction. The floating cylinder 20 provides appropriate axial clearance capacity through a buffer structure or flexible connection method to absorb the slight axial difference generated during the connection process during torque loading, thereby reducing the impact risk and improving meshing stability.
[0047] The torque detection assembly 30 includes a servo motor 310, a reducer 320, a connecting shaft 330, a quick-release flange 340, and a gauge connector 350. The servo motor 310 is mounted on the movable end of the floating cylinder 20 so that it moves synchronously with the movement of the movable end. The output end of the servo motor 310 is connected to the input end of the reducer 320 to convert high-speed, low-torque output into low-speed, high-torque output. The output end of the reducer 320 is connected to a connecting shaft 330, which is designed as a floating shaft. Its free-floating stroke is approximately equal to the depth of the end groove of the connector, allowing the gauge connector 350 to achieve axial progressive rotation during thread engagement with the connector. The other end of the connecting shaft 330 is equipped with a quick-release flange 340, which is detachably connected to the gauge connector 350 via a mechanical snap-fit or threaded locking structure, enabling quick replacement or maintenance of the gauge connector 350. The GO connector 350 is customized according to the end slot type of the connector being inspected, and is usually a standard plug structure that matches the end slot size and thread shape.
[0048] During operation, the control system first controls the lifting assembly 10 to move the entire torque detection assembly 30 downwards. When the movable end of the floating cylinder 20 moves to the preset stroke position, the go gauge connector 350 is inserted into the end slot of the connector, and the threaded insertion and torque loading process is achieved by the servo motor 310. The floating shaft and the floating cylinder 20 work together to provide a buffer during insertion and a progressive meshing function during the screwing process, effectively avoiding hard collisions and structural damage, and ensuring the stability and repeatability of torque detection.
[0049] This device is suitable for automated assembly lines with relatively limited space, and is particularly well-suited for inspection scenarios with vertically installed connection structures. It is recommended to install the device on an assembly platform with rigid support or at the end of a robot. Applicable working environments include those with a temperature control range from ambient to high temperatures and without the presence of corrosive gases.
[0050] In this embodiment, because the technical solution adopts a bidirectional moving structure including a floating cylinder 20 and a lifting component 10, and is combined with a connecting shaft 330 and a quick-release gauge connector 350, it effectively solves the problems of collision, damage and meshing difficulties caused by position deviation or rigid connection between the gauge connector 350 and the connector end slot during automatic insertion in the prior art. This achieves the integration of multiple functions such as insertion buffer, progressive screwing, automatic alignment and quick replacement, effectively improving the reliability, ease of operation and structural adaptability of the detection system.
[0051] To ensure that the floating shaft always has sufficient travel margin for adaptive displacement throughout the axial stroke of the entire screwing process, in some embodiments, the floating distance of the floating shaft is equal to the depth of the end groove of the connector.
[0052] Specifically:
[0053] The floating shaft has a defined axial floating distance to provide progressive axial clearance during thread engagement between the gauge connector 350 and the connector. The floating distance is set to be equal to the end groove depth of the connector, ensuring that the floating shaft always has sufficient travel margin for adaptive displacement throughout the axial stroke of the entire screwing process.
[0054] The floating shaft can limit its floating stroke through a spring assembly, guide pin, or sliding sleeve structure, and remain in its initial position when not in operation. When the gauge connector 350 begins to be threaded into the end slot of the connector, the connecting shaft 330 generates a rotational torque driven by the servo motor 310. During the screwing process, if there is a slight difference in thread engagement or a change in local friction between the end slot of the connector and the gauge connector 350, the floating shaft can make room in the axial direction to buffer the engagement resistance during the screwing process, allowing the threaded connection process to proceed gradually and avoiding impact loads caused by rigid connections.
[0055] This structure is particularly suitable for connection scenarios requiring precise torque loading, such as high-precision threaded connection testing stations, and can significantly reduce the risk of false detections caused by meshing instability or engagement deviation. The floating shaft should be made of high-strength, fatigue-resistant alloy steel or high-strength engineering plastic, and its maximum floating distance should be limited by an end stop structure to prevent detachment or over-travel deformation.
[0056] When using the equipment, it is essential to ensure the stability of the connection between the floating shaft and the output end of the reducer 320 or the quick-release flange 340. Keyed connections, splines, or adjustable couplings can be used. The bushing structure where the floating mechanism is located should have good lubrication and dustproof performance, making it suitable for long-term operation on automated production lines. The operating environment temperature can be from room temperature to medium temperature. It is not suitable for use in highly corrosive or severely impacted conditions. If necessary, a flexible protective cover or sealing structure can be used.
[0057] In this embodiment, since a floating shaft structure is used in this technical solution and its floating distance is set to be equal to the depth of the end groove of the connector, the meshing impact, connection damage or torque error caused by axial rigidity limitation during the thread engagement of the go gauge connector 350 in the prior art is effectively solved. This achieves a synergistic improvement in progressive meshing, adaptive clearance and torque loading stability during the engagement process, thereby improving the reliability, accuracy and structural safety of the detection process.
[0058] To provide precise positioning and spatial adjustment capabilities in multiple degrees of freedom and to meet the access and insertion requirements in complex installation scenarios, in some embodiments, the quick-release torque measuring mechanism further includes a first displacement component 40 and a second displacement component 50. The first displacement component 40 includes a first movable end that is controlled to move, and the movement trajectory of the first movable end is perpendicular to the movement trajectory of the lifting end. The second displacement component 50 is connected to the first movable end and includes a second movable end that is controlled to move, and the movement trajectory of the second movable end is perpendicular to the movement trajectory of the first movable end and also perpendicular to the movement trajectory of the lifting end. The second movable end is connected to the lifting component 10.
[0059] Specifically:
[0060] The first displacement component 40 includes a controllable movable first moving end. The movement trajectory of the first moving end is perpendicular to the movement trajectory of the lifting end of the aforementioned lifting component 10, that is, it moves in the horizontal direction, forming an orthogonal complement to the vertical lifting direction. The first displacement component 40 may be an electric slide, a linear guide 70 module, a servo module, or a stepper propulsion mechanism with a ball screw, etc., and is installed on the lower part or side fixed platform of the device.
[0061] The second displacement component 50 is connected to the first moving end and includes a controllable moving second moving end. The movement trajectory of the second moving end is perpendicular to the movement trajectory of the first moving end and also perpendicular to the movement trajectory of the lifting end, thereby providing omnidirectional movement capability in three orthogonal directions in a three-dimensional coordinate system. The second displacement component 50 preferably adopts a compact and highly precise linear module, forming a multi-axis linkage platform with the first displacement component 40 to support the movement and adjustment of the overall lifting component 10.
[0062] The second moving end is connected to the lifting component 10, that is, the lifting component 10 is installed on the output end of the second displacement component 50, so that the entire lifting-floating-detection structure can perform fine-tuning and alignment operations in space with the multi-axis moving platform as an execution unit.
[0063] In actual operation, the control system sequentially controls the movement of the first displacement component 40 and the second displacement component 50. First, the lifting component 10 is moved horizontally to directly above the target installation position, and then the lifting action is used to achieve precise insertion of the gauge connector 350. This three-axis orthogonal displacement structure can adapt to the positioning requirements of the tested connector located at different heights, horizontal misalignments, or complex layout areas, and is especially suitable for torque testing platforms that operate on mixed lines of multiple models and specifications of equipment.
[0064] This structure is suitable for automated production lines with flexible equipment space requirements. It can also be combined with vision systems or position coding systems to achieve high-precision plug-in position recognition and automated control. The device can operate in general industrial plant environments under normal temperature conditions. If a dustproof or protective housing structure is selected, it can also adapt to complex working conditions with dust or splashes.
[0065] In this embodiment, since the technical solution uses a double orthogonal moving platform composed of the first displacement component 40 and the second displacement component 50, and links with the lifting component 10 to realize three-dimensional spatial positioning adjustment, it effectively solves the problem that the torque detection structure in the prior art cannot flexibly connect to connectors at different positions or heights. This realizes the multi-degree-of-freedom alignment capability, spatial layout adaptability and insertion flexibility under complex working conditions of the torque detection mechanism, and significantly improves the versatility and deployment efficiency of the detection system.
[0066] To achieve stable guidance and linear sliding engagement of the lifting assembly 10 during spatial position control, in some embodiments, the quick-release torque measuring mechanism further includes a linear guide rail 70, a slider 80, and a moving plate 90. The lifting assembly 10 is disposed on one side of the base plate 60, the second moving end is connected to the base plate 60, the linear guide rail 70 is disposed on the side of the base plate 60, the slider 80 slides with the linear guide rail 70, causing the slider 80 to move along the extension direction of the linear guide rail 70, the extension direction of the linear guide rail 70 being parallel to the movement trajectory of the lifting end, the moving plate 90 is disposed on one side of the slider 80 and connected to the lifting end, the floating cylinder 20 is disposed on one side of the moving plate 90, and the moving plate 90 is configured to move along the linear extension direction of the linear guide rail 70 with the slider 80 when the lifting end moves.
[0067] Specifically:
[0068] The device as a whole is provided with a base plate 60 structure for mounting and supporting various execution modules. The lifting assembly 10 is disposed on one side of the base plate 60, and its output end, i.e., the lifting end, is mechanically connected to the moving plate 90 for transmitting lifting motion to the torque detection assembly 30. The second moving end is fixedly connected to the top of the base plate 60, so that the base plate 60 serves as a motion transmission structure and docks with an external multi-axis moving platform.
[0069] The linear guide rail 70 is disposed on the side of the base plate 60, and its installation direction is parallel to the moving trajectory of the lifting end. The slider 80 is slidably engaged with the linear guide rail 70, and can move with low friction in the linear extension direction of the guide rail. The slider 80 preferably uses a high-precision roller slider 80 or a ball slider 80 to achieve a balance between guiding stability and service life. The moving plate 90 is fixedly mounted on the slider 80. The moving plate 90 serves as a connecting structure, with one side connected to the lifting end and the other side used to fix the floating cylinder 20, thereby driving the slider 80 as a whole to move in the direction of the linear guide rail 70 when the lifting assembly 10 is actuated.
[0070] This structural design achieves coordinated operation between lifting drive and linear guidance: when the lifting end moves vertically, since the moving plate 90 and the slider 80 are connected as a whole, the slider 80 slides on the guide rail accordingly, thereby ensuring that the entire floating cylinder 20 and the detection component always move stably along the guide rail direction, avoiding problems such as mechanism jamming and movement jumping caused by lateral deflection, poor guidance or assembly errors.
[0071] This structure is suitable for precision testing scenarios requiring high stability, especially for torque measurement modules that are large or heavy and require smooth movement. It effectively suppresses lateral sway during lifting and lowering movements and improves alignment accuracy during insertion. It is applicable to automated assembly workshops, equipment testing platforms, and other environments requiring multi-axis linkage positioning. During installation, ensure the base plate is 60° flat and the guide rail axes are parallel. It is recommended to use it with limit sensors and lubrication components to improve motion control accuracy and extend system lifespan.
[0072] In this embodiment, because the technical solution adopts a linear guide structure consisting of a linear guide rail 70, a slider 80, and a moving plate 90, and is linked to the lifting end and the floating cylinder 20, it effectively solves the problem that the detection component is prone to guide offset, insertion error, or structural shaking during the lifting drive process in the prior art. This achieves a simultaneous improvement in the guide stability, displacement accuracy, and structural reliability of the torque detection device during the lifting operation, and enhances the smoothness of operation and control accuracy of the overall measuring mechanism.
[0073] To further enhance the automatic return capability of the movable end after being subjected to force during insertion or loading, and to optimize the overall flexible response performance and stability of the machine, in some embodiments, the floating cylinder 20 in the quick-release torque measuring mechanism is provided with a reset spring structure for providing a self-resetting function. One end of the reset spring is connected to the movable end, and the reset spring is configured to compress when the movable end moves under pressure; and the reset spring applies a spring force to the movable end in a direction opposite to the direction of pressure.
[0074] Specifically:
[0075] The return spring can be a compression spring, with one end fixed to the inner wall of the floating cylinder 20 housing and the other end connected to the movable end. When the movable end is subjected to external force and moves axially inward during the insertion of the gauge connector 350 into the connector end slot, the return spring undergoes axial compression deformation, absorbing part of the insertion force and providing cushioning. After insertion is completed or external pressure is released, the return spring returns to its original shape according to its own elasticity characteristics, thereby driving the movable end to automatically return to its initial position.
[0076] This structural design allows the floating cylinder 20 to have axial clearance capability under force while resetting without external control after the external force disappears, effectively improving the smoothness of the insertion process and the automation level of the device. The stiffness coefficient of the reset spring can be selected according to the size of the go-go connector 350, the insertion force, and the shape of the end groove of the connector. It is advisable to choose a metal spring material with high resilience and fatigue resistance, such as piano wire or stainless steel wire. The installation structure must ensure that the working stroke of the spring matches the floating stroke to avoid overpressure damage.
[0077] This structure is particularly suitable for scenarios involving multiple insertions and batch testing, effectively reducing structural wear and response hysteresis caused by the insertion and removal of the testing head. Applicable operating conditions include automated production lines or testing equipment platforms with constant temperature drying. For use in environments with high-frequency vibration or impact, a damping structure can be added to improve reset stability.
[0078] In this embodiment, the technical solution adopts a structure design that sets a reset spring in the floating cylinder 20, so that the movable end can be compressed after being pressed during the insertion process and automatically reset after unloading. Therefore, it effectively solves the problem that the detection component cannot achieve automatic return after insertion in the prior art, resulting in low efficiency of repeated insertion and unstable alignment. Thus, it realizes automatic reset, flexible response and efficient operation of the torque measuring mechanism during the insertion process, and improves the stability, adaptability and automation of the device.
[0079] In order to determine in real time whether the movable end has moved to the preset stroke position, thereby assisting in controlling the insertion action of the gauge connector 350 and the connector end slot, in some embodiments, the quick-release torque measuring mechanism further includes a position sensor 1000 and a reflection component 1010. The position sensor 1000 is disposed on the torque detection component 30 to emit a detection signal, and the reflection component 1010 is disposed on the moving plate 90 to reflect the detection signal. The position sensor 1000 and the reflection component 1010 are configured such that when the movable end moves to the preset stroke, the position sensor 1000 receives the reflected signal from the reflection component 1010. The reflective assembly 1010 includes a first reflector 1011 and a second reflector 1012. The first reflector 1011 is disposed on the movable plate 90 to reflect the detection signal to the position sensor 1000 when the position sensor 1000 moves past the first reflector 1011. The second reflector 1012 is disposed on the movable plate 90 to reflect the detection signal to the position sensor 1000 when the position sensor 1000 moves past the second reflector 1012. The distance between the orthographic projection of the second reflector 1012 in the vertical direction and the orthographic projection of the first reflector 1011 in the vertical direction is equal to the depth of the end groove of the connector.
[0080] Specifically:
[0081] The position sensor 1000 is mounted on the torque detection assembly 30. Preferably, it is a photoelectric position sensor 1000, which has the function of emitting detection signals and receiving reflected signals. The installation direction is towards the moving plate 90. The moving plate 90 serves as a detection target platform, on which the reflection assembly 1010 is disposed. The reflection assembly 1010 includes a first reflector 1011 and a second reflector 1012, both of which are fixedly disposed on the moving plate 90 and located at different heights along the sensor scanning path.
[0082] During operation, as the movable end moves downward with the floating cylinder 20, the position sensor 1000 sequentially aligns with the first reflector 1011 and the second reflector 1012. Whenever the detection signal from the position sensor 1000 is reflected back by a reflector and successfully received, the control system records the current displacement state of the movable end. The first reflector 1011 marks the initial insertion position, and the second reflector 1012 marks the insertion end point. Specifically, the vertical projection distance between the two is set to be equal to the depth of the connector end groove, thereby ensuring that the gauge connector 350 is inserted precisely to the specified depth.
[0083] This displacement detection structure not only enables non-contact real-time feedback but also boasts strong anti-interference capabilities and fast response speed. It is suitable for highly automated torque detection systems, particularly in high-cycle, multi-product assembly lines, facilitating automatic calibration and process control. During installation, ensure the reflector surface is clean and that the sensor and reflector are aligned perpendicularly to avoid signal loss due to reflection angle deviation.
[0084] In this embodiment, because the technical solution employs a position sensor 1000 mounted on the torque detection component 30 and a first reflector 1011 and a second reflector 1012 mounted on the moving plate 90, and the vertical distance between the two reflectors is equal to the depth of the connector end groove, the problem that the insertion depth or endpoint position of the gauge connector 350 cannot be accurately determined during the insertion process in the prior art is effectively solved. This achieves high-precision identification of the insertion endpoint, improved process control and detection safety during the insertion process, and enhances the intelligence and operational stability of the device.
[0085] In some embodiments, the position sensor 1000 is a photoelectric sensor, and the first reflector 1011 and the second reflector 1012 are both reflective plates. Together, they form a non-contact displacement detection system based on light signal reflection, which is mainly used to determine whether the torque detection component 30 has reached the preset insertion stroke.
[0086] Specifically:
[0087] The photoelectric sensor is fixedly mounted on the torque detection assembly 30, with its orientation set to face the side where the movable plate 90 is installed. The photoelectric sensor includes a transmitting unit and a receiving unit. The transmitting unit emits a light signal of a specific wavelength, such as infrared or visible light, and the receiving unit receives the light signal reflected back from the target surface. The first reflector 1011 and the second reflector 1012 are disposed on the surface of the movable plate 90, arranged vertically at intervals along the sensor scanning path. Both are made of a smooth, highly reflective material, such as mirror-finished stainless steel or glass-coated reflective sheets, possessing excellent reflective properties and anti-fouling capabilities.
[0088] As the torque detection assembly 30 moves with the movable end, the photoelectric sensor sequentially detects the reflected signals from the first and second reflectors. By identifying the reflected signals, the system can accurately determine the current position of the movable end. In particular, the vertical spacing between the two reflectors is designed to be equal to the depth of the connector end groove. Therefore, when the photoelectric sensor detects the second reflector, it can be confirmed that the go gauge connector 350 has reached the fully inserted state.
[0089] This detection system features non-contact operation, high response, and high precision, making it suitable for multi-batch, high-frequency automatic insertion detection tasks. Its signal output can be directly connected to the input interface of the control system, working in conjunction with control logic to stop movement, apply torque, or record detection data. During installation and use, ensure there are no foreign objects obstructing the reflector and sensor, the surfaces are clean, and the working environment avoids strong light interference and dust contamination. If necessary, a light shield and dustproof housing can be added.
[0090] In this embodiment, since a photoelectric sensor is used as the position sensor 1000 and the first and second reflective plates are used as the cooperating reflective targets to form a non-contact position detection system, the problems of the insertion depth not being able to be sensed in real time, mechanical limit being prone to wear, and detection accuracy being unstable in the prior art are effectively solved. Thus, the accurate identification and process control of the insertion stroke state of the torque detection mechanism are realized, and the intelligence, reliability and operation efficiency of the detection system are improved.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
