Description

Technical Field

[0001] This utility model belongs to the technical field of detection devices, specifically, it relates to a torque sensor fixing detection device. Background Technology

[0002] Torque is a special type of force that causes an object to rotate. Torque sensors are widely used for detecting torque in shaft systems. To ensure the accuracy and reliability of test data, torque sensors need to be tested.

[0003] A certain torque is applied to both the standard torque sensor and the torque sensor being calibrated. The values ​​of the standard torque sensor and the torque sensor being calibrated are then read and compared to determine whether the torque sensor being calibrated meets the testing requirements.

[0004] Existing equipment for testing static torque sensors is costly and cumbersome. The installation of positioning stakes involves adjusting their position by installing them in different threaded holes. This method makes it difficult to ensure that the pressure exerted on the torque sensor by two opposing positioning stakes is synchronized, leading to measurement deviations. If the standard torque sensor deviates too much, the test results will be inaccurate. Therefore, a torque sensor fixing and testing device is needed to solve these problems.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0016] Optionally, the telescopic rod includes a rectangular fixed rod, with a sleeve fitted and slidably engaged on the outer side of the rectangular fixed rod, and the sleeve being fixedly connected to the fixed shell.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] 1. The first stage of clamping is achieved by the lateral movement of the sliding shell, and the second stage of clamping is achieved by the longitudinal movement of the rubber fixing rod. The rubber fixing rod provides flexible contact, which not only protects the sensor surface, but also adapts to different shapes, enhances the clamping force and shockproof effect, and forms a stable and flexible double fixation for the torque sensor, which can prevent the torque sensor from slipping or shifting during the test.

[0019] 2. By utilizing the inclined and right-angle structures of the first rack and the first locking block, and the second rack and the second locking block, a simple operation of pushing in self-locking and pressing to unlock is achieved. After fixing, it automatically locks to ensure test stability.

[0020] 3. Press the pressure plate to drive the card plate to move down, simultaneously releasing the locking state of the first stage (sliding shell) and the second stage (rubber fixing rod), which facilitates manual operation to release the fixing of the torque sensor, so as to achieve the effect of quickly replacing the torque sensor that needs to be tested;

[0021] 4. The telescopic rod design allows the fixed part at the end of the support frame to move in a straight line through the rectangular fixed rod and sleeve, thereby accommodating torque sensors of different lengths.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Please see Figure 1-4 As shown, this embodiment provides a torque sensor fixing detection device, including: a torque detector 1, a display panel 2 installed on one side of the torque detector 1, a support frame 3 installed on the upper side of the torque detector 1, and fixing parts 4 provided on the lower side of the support frame 3 and the driving end on the upper side of the torque detector 1.

[0033] The fixing component 4 includes a fixing shell 401, within which a clamping plate 402 is elastically and slidably fitted. Two sliding shells 403 are slidably fitted on the upper side of the fixing shell 401, and two rubber fixing rods 404 are slidably fitted within each sliding shell 403. A clamping strip 405 is slidably connected to the clamping plate 402 within each sliding shell 403. The first level of clamping is achieved through the lateral movement of the sliding shells 403, and the second level of clamping is achieved through the longitudinal movement of the rubber fixing rods 404. The rubber fixing rods provide flexible contact, protecting the sensor surface and adapting to different shapes, enhancing clamping force and shock absorption, thus forming a stable yet flexible dual fixation for the torque sensor, preventing slippage or displacement during torque sensor testing.

[0034] In this embodiment, the support frame 3 is an inverted L-shaped support frame.

[0035] In this embodiment, the fixed housing 401 has openings 406 on both opposite outer sides, and the clamping plate 402 has pressure plates 407 on both sides, with the pressure plates 407 slidably fitted within the openings 406. Pressing the pressure plates 407 drives the clamping plate 402 to move downward, simultaneously releasing the locking state of the first-stage sliding housing 403 and the second-stage rubber fixing rod 404, facilitating manual operation to release the torque sensor and achieve the effect of quickly replacing the torque sensor that needs to be detected;

[0036] In this embodiment, the upper surface of the fixed shell 401 has two channels 412, the upper surface of the locking plate 402 has two first racks 408, the teeth of the two ends of the first racks 408 are opposite in direction, and the lower sides of the sliding shell 403 are elastically fitted with first locking blocks 409, which are slidably fitted in the channels 412; the upper surface of the locking strip 405 has a second rack 410, the teeth of the two ends of the second rack 410 are opposite in direction, and one end of the rubber fixing rod 404 is elastically fitted with a second locking block 411. By utilizing the inclined and right-angled structures of the first racks 408 and the first locking blocks 409, and the second racks 410 and the second locking blocks 411, a simple operation of pushing in self-locking and pressing to unlock is achieved, and it automatically locks after being fixed to ensure test stability;

[0037] In this embodiment, the upper surface of the fixed shell 401 is provided with a first sliding groove 413, the upper surface of the card plate 402 is provided with a second sliding groove 414, and the bottom of the sliding shell 403 is provided with a connecting block 415, which passes through the first sliding groove 413 and is slidably connected in the second sliding groove 414.

[0038] The torque detector 1 in this embodiment is equipped with a drive device, and the output end of the drive device is provided with a rotating shaft 5, which is fixedly connected to one of the fixed shells 401.

[0039] In this embodiment, a telescopic rod 6 is installed at the bottom of the support frame 3. The telescopic end of the telescopic rod 6 is fixedly connected to another fixed shell 401. The telescopic rod 6 in this embodiment includes a rectangular fixed rod 601. A sleeve 602 is sleeved and slidably fitted on the outer side of the rectangular fixed rod 601. The sleeve 602 is fixedly connected to the fixed shell 401. The design of the telescopic rod 6 allows the fixing member 4 at the end of the support frame to move in a straight line through the rectangular fixed rod 601 and the sleeve 602, thereby accommodating torque sensors of different lengths. The drive end of the torque detector is directly connected to the fixed shell 401 through the rotating shaft 5, ensuring effective torque transmission and a compact structure.

[0040] In this embodiment, both the sliding shell 403 and the rubber fixing rod 404 have storage slots on their lower sides for storing the first locking block 409 and / or the second locking block 411. The first locking block 409 and / or the second locking block 411 are elastically engaged in the storage slots by springs.

[0041] How to use:

[0042] like Figure 1-4 As shown: When testing the torque sensor, first place the torque sensor on the fixing part 4 of the torque detector 1, and place the torque detector on the fixing housing 401. Then, manually push the two sliding housings 403. The sliding housings 403 move closer to each other along the second sliding groove 414 and the channel 412, and drive the rubber fixing rods 404 closer to the torque sensor. After the sliding housings 403 contact the torque sensor, manually push the two rubber fixing rods 404 inside the sliding housings 403. The two rubber fixing rods 404 move closer to each other, thus testing the torque sensor. By squeezing and clamping, the torque detector can be initially fixed. Then, manually pull the fixing part 4 on the lower side of the support frame 3. The fixing part 4 moves and moves towards the side closer to the torque sensor under the guidance of the rectangular fixing rod 601 through the sleeve 602. Referring to the above steps, the two ends of the torque sensor are fixed. At this time, the drive device of the torque detector 1 is started, so that the output end of the drive device drives the rotating shaft 5 to rotate, which in turn drives the fixing part 4 on the torque detector 1 to twist. The torque value is displayed on the display panel 2, which is convenient for the user to record in real time.

[0043] After the torque sensor completes its detection, the two pressure plates 407 are manually pressed. The pressure plates 407 cause the clamping plate 402 to descend, which in turn causes the first rack 408 to descend, releasing the engagement with the first clamping block 409. At this time, the two sliding shells 403 can move away from each other, releasing the fixation on the torque sensor. Simultaneously, as the clamping plate 402 descends, the connecting block 415 causes the second rack 410 to descend, releasing the engagement between the second rack 410 and the second clamping block 411. This allows the two rubber fixing rods 404 inside the sliding shell 403 to move away from each other and reset.

[0044] Among them, the teeth of the first locking block 409, the second locking block 411, the second rack 410 and the teeth of the first rack 408 are all right-angled triangles. When the user pushes the two sliding shells 403 closer to each other or pushes the two rubber fixing rods 404 closer to each other, the inclined surfaces of the two teeth will abut against each other, and the teeth will retract into the storage groove. After the torque sensor is squeezed, clamped and fixed, the teeth can fix the position of the sliding shell 403 or the rubber fixing rod 404 through the abutment on the plane side.

[0045] In this embodiment, the sliding groove 414 and the inner sidewall of the sliding shell 403 are provided with limiting grooves on opposite sides. The connecting block 415 and the outer sidewall of the rubber fixing rod 404 are provided with limiting blocks on opposite sides. The limiting blocks are slidably engaged in the limiting grooves. This allows the card plate 402 to move through the connecting block 415 to drive the second rack 410 to move without affecting the sliding of the connecting block 415. It also prevents the rubber fixing rod 404 from detaching from the sliding shell 403 without affecting the sliding of the rubber fixing rod 404.

[0046] To facilitate the use of fastener 4, the following two embodiments are proposed to improve the convenience of using fastener 4;

[0047] Example 1: In this example, a tension spring is installed between the second slide groove 414 and the connecting block 415. With the tension spring, when the locking plate 402 descends and releases its engagement with the first locking block 409, the tension of the spring causes the two sliding shells 403 to quickly move away from each other, thereby achieving a rapid reset effect.

[0048] Example 2: In this example, a tension spring is installed between the sliding shell 403 and the rubber fixing rod 404. The tension spring allows the two rubber fixing rods 404 to quickly move away from each other when the locking strip 405 descends and releases its engagement with the second locking block 411, thus achieving a rapid reset effect.

[0049] This embodiment 2 can be used in conjunction with embodiment 1, so that when the card plate 402 descends, the connecting block 415 and the rubber fixing rod 404 can achieve a rapid reset effect;

[0050] Example 3: The rubber fixing rod 404 in this example includes a sliding part and a clamping part. The sliding part is located inside the sliding shell 403, and the diameter of the clamping part is larger than the width of the sliding shell 403. The clamping part and the sliding part are connected by a lead screw. This facilitates user replacement of the rubber fixing rod 404.

[0051] Example 4: In this example, a connector is provided between the two rubber fixing rods 404 on the two fixing members 4. When in use, the fixing shell 401 on the lower side of the support frame 3 can be pulled first to bring the two fixing shells 401 closer to each other, and the opposite rubber fixing rods 404 are connected by the connector, so that the user can synchronously control the two fixing members 4 to squeeze and clamp the torque sensor.

[0052] Example 5: In this example, the bottom of the second slide 414 is rotatably fitted with a gear, and toothed plates are installed on the opposite surfaces of the two connecting blocks 415. The gear meshes with the two toothed plates. Through the gear and toothed plates, the two connecting blocks 415 can move synchronously.

[0053] Example 6: In this example, the bottom of the sliding shell 403 is rotatably fitted with a gear, and toothed plates are installed on the opposite surfaces of the two rubber fixing rods 404. The gear meshes with the two toothed plates, enabling the two rubber fixing rods 404 to move synchronously.

[0054] This utility model provides multiple embodiments (Embodiment 1 to Embodiment 6). The technical features of each embodiment can be combined with each other without conflict to form different technical solutions to adapt to different application scenarios.
