Abstract
Description
Technical Field

[0002] A torque limiter, also known as a safety coupling, is a component that connects the drive engine and the working machine. Its primary function is overload protection. When the required torque exceeds the set value due to overload or mechanical failure, the torque limiter limits the torque transmitted by the transmission system by slipping. When the overload condition disappears, the connection is restored automatically. Therefore, to ensure that the torque limiter can reliably and accurately perform its protective role in actual applications, it must undergo rigorous testing before leaving the factory. During this testing process, a certain load is usually applied to the torque limiter to simulate actual operating conditions and evaluate its performance.

DETAILED DESCRIPTION
[0020] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0021] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.
[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.
[0023] The torque limiter detection device provided in this embodiment is used for torque limiter detection in scenarios such as vehicle body power structures and mechanical equipment, especially in fields where overload protection detection is required; wherein, the torque limiter, also known as a safety coupling, is a coupling structure that limits the transmission torque through a slipping mechanism in the event of overload or mechanical failure, thereby avoiding system damage; in this embodiment, the specific structure of the torque limiter detection device is improved, so that the detection accuracy is improved.
[0024] like Figures 1 to 7 As shown, the torque limiter detection device provided in this embodiment specifically includes a frame 100, a driving assembly 200, a transmission member 300 and a loading assembly 400; a torque limiter detection station 101 is provided on the frame 100; The drive assembly 200 is arranged below the torque limiter detection station 101, and the rotating end of the drive assembly 200 is used to install the torque limiter. The drive assembly 200 includes but is not limited to structures such as a servo motor, a stepper motor, and a rotary cylinder. It only needs to have a rotating end, which extends from bottom to top and is used to install a torque limiter (not shown in the figure). The connection between the torque limiter and the rotating end is mainly achieved through the locking structure on the torque limiter, which is not specifically limited in this embodiment; the transmission member 300 is arranged above the torque limiter detection station 101 and is connected to the torque limiter. The connection between the transmission member 300 and the torque limiter is achieved through the locking structure on the torque limiter, which is not specifically limited in this embodiment. The transmission member 300 includes a cylindrical portion and a disc portion. The cylindrical portion is inserted into the torque limiter from top to bottom. The diameter of the disc portion is larger than that of the cylindrical portion, which facilitates the subsequent loading assembly 400 to provide load to the torque limiter through the disc portion.
[0025] like Figures 1 to 3 、 Figure 7As shown, the loading assembly 400 includes a pressure member 410 disposed radially on one side of the transmission member 300. The first spacing between the pressure member 410 and the transmission member 300 is adjustable, and the loading force of the loading assembly 400 is inversely proportional to the first spacing. It is understood that as the pressure member 410 approaches the transmission member 300, the loading force increases, thereby dynamically adjusting the loading force of the loading assembly 400. Furthermore, the loading assembly 400 also includes a locking member 420 disposed in correspondence with the pressure member 410. The locking member 420 is movable between an unlocked position and a locked position. The locked position is located on the end face of the pressure member 410 facing away from the transmission member 300. When the first spacing is less than or equal to the locked spacing, the locking member 420 is in the locked position and abuts against the pressure member 410. It should be noted that the unlocking position is a position where the locking part 420 and the pressure part 410 do not interfere with each other, and at this time the loading force is only related to the position of the pressure part 410; the locking position is a position where the locking part 420 interferes with the pressure part 410, and at this time the locking part 420 is arranged on the end face of the pressure part 410 away from the transmission part 300, restricting the locking part 420 from moving in the direction away from the transmission part 300, and playing the role of providing additional support for the pressure part 410.
[0026] Specifically, the torque limiter detection device in this embodiment, after the transmission member 300 and the torque limiter are installed on the rotating end of the drive assembly 200 in sequence, drives the transmission member 300 to rotate through the drive assembly 200; during the rotation of the transmission member 300, the first spacing is changed by changing the position of the pressure member 410, thereby changing the loading force of the loading assembly 400 on the transmission member 300, simulating the working condition of the torque limiter under different loads; then, when it is necessary to simulate the sudden increase in the load of the transmission member 300, the position of the pressure member 410 is changed so that the first spacing is less than or equal to the locking spacing, and the loading force is increased while the locking member 420 is moved to the locking position, and the locking member 420 is used to limit the pressure member 410 to prevent the pressure member 410 from retreating, ensuring that the torque limiter enters a slipping state, facilitating the subsequent accurate evaluation of the performance of the torque limiter, thereby improving the detection accuracy of the torque limiter detection device.
[0027] Further, if Figures 1 to 6As shown, the loading assembly 400 includes a loading shell 430 arranged on the frame 100, and the loading shell 430 is covered outside the torque limiter detection station 101; the loading shell 430 is provided with a slide 431 at the position corresponding to the pressure member 410, and the slide 431 is provided with a slide groove 432 along the radial direction of the transmission member 300; the pressure member 410 includes a first abutment member 411 and a second abutment member 412, the first abutment member 411 is passed through the slide groove 432, and is slidably connected to the slide groove 432; along the radial direction of the transmission member 300, the second abutment member 412 is slidably connected to the first abutment member 411, and a spring unit (not shown in the figure) is provided between the second abutment member 412 and the first abutment member 411, and the second abutment member 412 abuts against the first abutment member 411 through the spring unit, and the connection method between the spring unit and the above-mentioned abutment member includes but is not limited to welding, bonding, etc.
[0028] It can be understood that when the first abutment 411 is not in abutment with the transmission member 300, the second abutment 412 is pushed and pulled to push and pull the first abutment 411 through the spring unit; when the first abutment 411 is in abutment with the transmission member 300, the distance between the second abutment 412 and the transmission member 300 is the first distance, so that the compression amount of the spring unit is inversely proportional to the first distance, that is, as the first abutment 411 abuts with the transmission member 300 and cannot move further, further pushing the second abutment 412 in the direction close to the transmission member 300 will compress the spring unit, so that the elastic force of the spring unit increases, and the pressure of the first abutment 411 on the transmission member 300 is also increased accordingly, thereby realizing precise adjustment of the loading force.
[0029] As a specific embodiment, the first abutment 411 includes an abutment portion 4111, and a friction portion is embedded in the end of the abutment 4111 facing the transmission member 300, and the friction portion includes but is not limited to tungsten steel, alumina ceramics and other materials; the abutment 4111 is connected to a sliding portion 4112 on the side away from the transmission member 300, and the sliding portion 4112 is slidingly connected to the slide groove 432, and a loading space 4113 is formed in the sliding portion 4112; the second abutment 412 is slidingly connected to the sliding portion 4112, and the first end portion 4121 of the second abutment 412 passes through the sliding portion 4112 and extends into the loading space 4113, and the first end portion 4121 abuts against the abutment 4111 through a spring unit.
[0030] Specifically, the first abutment member 411 includes an abutment portion 4111, which has a friction portion embedded in one end thereof facing the transmission member 300. The embedding of the friction portion provides a stable loading surface, thereby ensuring the contact stability between the abutment portion 4111 and the transmission member 300 during the loading process and avoiding test errors caused by poor contact. The connection between the sliding portion 4112 and the slide groove 432 makes the displacement of the pressure member more precise, and the friction portion further enhances the stable transmission of the loading force, which can simulate a more realistic load state. In addition, the spring unit in the loading space 4113 acts on the abutment portion, and the change in the amount of compression can adjust the loading force according to the needs of the load conditions, which greatly improves the test accuracy and the reliability of the simulated load change.
[0031] Further, if Figure 4 and Figure 7 As shown, a transmission groove 433 is opened on the groove wall of the sliding groove 432, and a transmission assembly 440 is arranged in the transmission groove 433; the output end of the transmission assembly 440 is connected to the locking member 420; a trigger structure 450 is provided on the first end 4121, and when the first spacing is less than or equal to the locking spacing, the transmission assembly 440 is triggered by the trigger structure 450 to drive the locking member 420 to move to the locking position and abut against the end of the sliding portion 4112 away from the abutting portion 4111.
[0032] A transmission slot 433 is defined within the wall of the slideway 432, and a transmission assembly 440 is housed within the slot. This allows the transmission assembly 440 to be quickly triggered to move the locking member 420 to a locked position when the distance between the first abutment member 411 and the transmission member 300 reaches a set value. This structure not only allows the transmission assembly 440 to precisely control the position of the locking member 420, ensuring it moves to the locked position when the first distance is less than or equal to the locked distance, thus providing additional support for the pressure member 410, but also provides advantages such as a compact structure and stable transmission, as this structure is housed within the slideway 431.
[0033] As a specific embodiment, the transmission assembly 440 includes a meshing transmission gear 441 and an arcuate tooth plate 442, and the trigger structure 450 includes a rack portion arranged on the first end portion 4121; the transmission groove 433 includes a first connecting groove 4331 and a second connecting groove 4332 connected to each other, the transmission gear 441 is rotatably connected to the first connecting groove 4331, and the arcuate tooth plate 442 is rotatably connected to the second connecting groove 4332. The rotational connection method of the above-mentioned transmission gear 441 and the arcuate tooth plate 442 with the connecting groove is not limited, including but not limited to installing a rotating shaft on the gear / tooth plate and rotatably connecting the rotating shaft to the connecting groove; a guide column is provided on the gear / tooth plate, and a guide groove is opened on the side wall of the connecting groove, and the gear / tooth plate is limited by the sliding cooperation between the guide column and the guide groove; the end of the arcuate tooth plate 442 can extend from the second connecting groove 4332, and the end of the arcuate tooth plate 442 is fixedly connected to the locking member 420.
[0034] Understandably, the reference Figure 7 When the first spacing is less than or equal to the locking spacing, that is, when the rack portion moves to the right, the transmission gear 441 is correspondingly driven by the engagement of the rack portion to rotate counterclockwise; then, the transmission gear 441 drives the arc-shaped tooth plate 442 to rotate counterclockwise, causing the arc-shaped tooth plate 442 to extend from right to left, thereby driving the locking member 420 to move from the unlocked position to the locked position, just so that the locking member 420 can abut against the sliding portion 4112 of the first abutting member 411, specifically the left end portion of the sliding portion 4112, to lock the position of the first abutting member 411.
[0035] Furthermore, the loading assembly 400 includes multiple pairs of pressurizing elements 410 and locking elements 420, spaced apart around the transmission element 300. This design effectively enhances the uniformity and stability of the loading assembly. With this structure, the distribution of the pressurizing and locking elements ensures a more uniform loading force on the torque limiter, resulting in more accurate load simulation.
[0036] As a specific embodiment, the second end portion 4122 of the second abutment member 412, which is disposed away from the first abutment member 411, is connected to a pushing column 413; a driving ring 460 is provided on the outer ring of the torque limiter detection station 101, and the driving ring 460 is provided with a pushing block 461 corresponding to each pushing column 413, and the pushing block 461 is provided with a pushing surface, and the distance between the pushing surface and the frame 100 decreases along the direction approaching the transmission member 300; the pushing column 413 is slidably connected to the pushing surface; a lifting unit is provided on the frame 100, and the lifting end of the lifting unit is fixedly connected to the driving ring 460. The lifting unit includes but is not limited to structures such as a lifting cylinder, a lifting oil cylinder, and a telescopic rod motor. Among them, the second end portion 4122 of the second abutment member 412, which is disposed away from the first abutment member 411, is connected to the pushing column 413. Combined with the design of the drive ring 460 and the pushing block 461, when the pushing column is slidably connected to the pushing surface, the movement of the pressure member can be effectively adjusted, further enhancing the control accuracy of the loading assembly 400, and making the overall structure more compact and occupying a smaller area.
[0037] As another optional embodiment, a radially arranged air cylinder or oil cylinder may be arranged on a side of the second abutting member 412 away from the transmission member 300 to directly push the second abutting member 412 .
[0038] Furthermore, a collection barrel 500 is provided on the frame 100 outside the torque limiter inspection station 101. The inner wall of the collection barrel 500 is provided with a continuous diversion channel (not shown). The frame 100 is provided with an observation channel 102, which is connected to the diversion channel. The provision of the collection barrel 500 and the corresponding observation channel 102 on the frame 100 can effectively collect grease leaked during the operation of the torque limiter during the inspection process, ensuring that the grease is promptly and effectively collected and directed to the collection area when it leaks. This can reduce the risk of grease scattering or accumulation, and avoid contamination of the test environment and surrounding equipment. For torque limiters used over a long period of time, the leakage volume can also be accumulated and accurately recorded, providing basic data for subsequent leakage analysis and evaluation of the equipment's long-term performance. Therefore, the provision of the observation channel 102 can provide operators with a real-time view, facilitating monitoring of the situation and extent of grease leakage. Through visual observation, personnel can intuitively determine the torque limiter's grease leakage under different workloads and operating conditions. This is particularly effective during long-term operation tests, helping testers confirm the torque limiter's actual performance under high loads and determine whether there are any abnormal leaks or excessive wear. The visibility of observation channel 102 enhances the inspection process while ensuring a clean and tidy testing environment, facilitating subsequent operations.
[0039] Furthermore, along the vertical direction, the observation channel 102 is disposed in the gap between the two pressure members 410. The frame 100 is also provided with a horizontal moving device 600. The moving end of the horizontal moving device 600 is mounted with a vertical moving device 700. The lifting end of the vertical moving device 700 is mounted with a sensor unit. The sensor unit can pass through the gap between the two pressure members 410 and be partially inserted into the observation channel 102. The horizontal moving device 600 and the vertical moving device 700 include but are not limited to structures such as cylinders and linear motors, which can drive the sensor unit to move horizontally and can be lifted and lowered to be inserted into the observation channel 102. The sensor unit includes but is not limited to oil sensing wires, liquid sensors, etc., which can record the position of grease in the observation channel 102. For example, during multiple tests, the time when the grease reaches a certain position in the observation channel 102 under different tests can be recorded separately. The above arrangement can flexibly adjust the recording position and improve the flexibility of data recording.
[0040] Furthermore, the loading housing 430 has a circular clearance groove 434 located at the position corresponding to the transfer member 300. This clearance groove 434 also has an observation slot 435 located at the position corresponding to the lifting end of the vertical movement device 700. The circular clearance groove 434 in the loading housing 430, located at the position corresponding to the transfer member 300, provides the necessary space for the vertical movement device 700, ensuring its smooth operation. The observation slot 435 provides a clearer viewing angle for precise observation and data collection. This design enhances the flexibility of the inspection process and opens up more possibilities for precise adjustment and monitoring.
