Description

Technical Field

[0001] This utility model belongs to the field of torque sensor technology, and in particular relates to a test device for torque sensors. Background Technology

[0002] Torque sensors, also known as torque sensors, are divided into two main categories: dynamic and static. Torque sensors are used to detect torsional torque on various rotating or non-rotating mechanical parts. They convert the physical changes in torque into precise electrical signals. Torque sensors have advantages such as high accuracy, fast frequency response, high reliability, and long lifespan.

[0003] Existing torque sensor testing devices are not convenient for effectively positioning and fixing the torque sensor during testing, which affects the accuracy and repeatability of the test results. This inconvenience reduces testing efficiency to some extent, increases uncertainty in the experimental process, and forces operators to frequently adjust the sensor position to ensure measurement reliability. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for a torque sensor. By setting a fixing mechanism, the torque sensor can be positioned at the top center of the housing, achieving precise positioning of the torque sensor. This solves the problem that existing torque sensor testing devices are not convenient for effectively positioning and fixing the torque sensor when testing it.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a testing device for a torque sensor, including a housing, on which a fixing mechanism and a buffer mechanism are provided;

[0007] The fixing mechanism includes a motor fixedly connected to the front side of the housing. The output end of the motor is fixedly connected to a rotating rod via a coupling. A gear is fixedly connected to the outer wall of the rotating rod. Two sliding rails are fixedly connected to the inner wall of the housing. A rack is slidably connected to the side of each sliding rail that is close to each other. Both racks mesh with the gear. A slide rod is fixedly connected to the side of each rack that is far from each other. The ends of the slide rods that are far from each other extend to the left and right sides of the housing, respectively. Both slide rods are slidably connected to the housing.

[0008] Furthermore, hinge blocks are fixedly connected to the two sliding rods on opposite sides, and a rotating shaft is fixedly connected to each of the two hinge blocks.

[0009] Furthermore, two fixing blocks are fixedly connected to the top surface of the box, and two rotating shafts are fixedly connected to the inner walls of the two fixing blocks, and hinge rods are rotatably connected to the outer walls of the two rotating shafts.

[0010] Furthermore, the bottom ends of the two rotating shafts are slidably connected to the outer wall of the rotating shaft, the top ends of the two hinge rods are slidably connected to the rotating shafts, and the outer walls of the two rotating shafts are fixedly connected to the hinge blocks.

[0011] Furthermore, each of the two hinge blocks 2 has a sliding rod 2 fixedly connected to one of its adjacent sides. The two sliding rods 2 pass through the two fixed blocks respectively, and the two fixed blocks are slidably connected to the two sliding rods 2 respectively.

[0012] Furthermore, the buffer mechanism includes dampers that are fixedly connected to one end of two slide rods that are close to each other. Clamping plates are fixedly connected to one end of each of the two dampers that are close to each other. A torque sensor is placed on the top surface of the housing.

[0013] Furthermore, springs are wound around the outer walls of both dampers, one end of each spring is fixedly connected to two slide rods, and the other end of each spring is fixedly connected to two clamping plates. A torque input end is provided on the top surface of the torque sensor, and a torque rod is inserted into the torque input end through a keyway.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting a fixed mechanism, under the limit of the sliding track, the two racks can only slide left and right inside the box. When the motor starts, it drives the rotating rod inside the box to rotate. The rotating rod drives the gear to rotate. When the gear rotates, it drives the upper and lower connected racks to move away from each other or move closer to each other. With the cooperation of the two slide rods, when the two racks move away from each other, they drive the two hinge blocks to move, so that the hinge rod rotates on the outer wall of the rotating shaft, so that the two hinge blocks on the two rotating shafts move closer to each other. The two hinge blocks drive the two slide rods to move towards the torque sensor at the same time, so that the torque sensor can be positioned at the top center of the box, realizing the precise positioning of the torque sensor.

[0016] 2. By incorporating a buffer mechanism, when the two sliding rods approach each other, they will cause the two clamping plates to approach the torque sensor. After the clamping plates contact the torque sensor, the position of the torque sensor can be fixed to prevent the torque sensor from shaking during the detection process. The two dampers work together with the clamping plates to reduce the clamping force and prevent excessive clamping force from damaging the torque sensor, further improving the stability of the entire device during the detection process. After clamping and positioning the torque sensor, a torque rod can be inserted into the torque input end of the torque sensor, and the torque sensor can be detected by twisting the torque rod.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a testing device for a torque sensor, including a housing 1, on which a fixing mechanism 2 and a buffer mechanism 3 are provided;

[0028] The fixing mechanism 2 includes a motor 21 fixedly connected to the front side of the housing 1. The output end of the motor 21 is fixedly connected to a rotating rod 22 via a coupling. A gear 23 is fixedly connected to the outer wall of the rotating rod 22. Two sliding rails 24 are fixedly connected to the inner wall of the housing 1. A rack 25 is slidably connected to the side of each sliding rail 24 that is close to each other. Both racks 25 mesh with the gear 23. A slide rod 26 is fixedly connected to the side of each rack 25 that is far from each other. The far ends of the slide rods 26 extend to the left and right sides of the housing 1, respectively. Both slide rods 26 are slidably connected to the housing 1. A hinge block 27 is fixedly connected to the side of each slide rod 26 that is far from each other. A rotating shaft 28 is fixedly connected to each hinge block 27. Two fixing blocks 291 are fixedly connected to the top surface of the housing 1. A rotating shaft 292 is fixedly connected to the inner wall of each fixing block 291. The outer walls of the two rotating shafts 292 are rotatably connected to hinge rods 29. The bottom ends of the two rotating shafts 292 are slidably connected to the outer walls of the rotating shaft 28. The top ends of the two hinge rods 29 are slidably connected to rotating shafts 293. The outer walls of the two rotating shafts 293 are fixedly connected to hinge blocks 294. The sides of the two hinge blocks 294 that are close to each other are fixedly connected to slide rods 295. The two slide rods 295 pass through the two fixed blocks 291. The two fixed blocks 291 are slidably connected to the two slide rods 295. With the fixed mechanism 2, when the motor 21 starts, it drives the rotating rod 22 inside the housing 1 to rotate, causing the hinge blocks 294 on the two rotating shafts 293 to move closer to each other. This causes the two hinge blocks 294 to move towards the torque sensor 4 while simultaneously driving the two slide rods 295, so that the torque sensor 4 can be positioned at the top center of the housing 1.

[0029] The buffer mechanism 3 includes dampers 31 fixedly connected to the two slide rods 295 at their adjacent ends. Clamping plates 32 are fixedly connected to the adjacent ends of the two dampers 31. A torque sensor 4 is placed on the top surface of the housing 1. Springs 33 are wound around the outer walls of the two dampers 31. One end of each spring 33 is fixedly connected to the two slide rods 295, and the other end is fixedly connected to the two clamping plates 32. A torque input end 41 is provided on the top surface of the torque sensor 4. A torque rod 42 is inserted into the torque input end 41 via a keyway. A buffer mechanism 3 is provided. When the two slide bars 295 approach each other, they will drive the two clamping plates 32 to approach the torque sensor 4. After the clamping plates 32 contact the torque sensor 4, the position of the torque sensor 4 can be fixed to prevent the torque sensor 4 from shaking during the detection process. The two dampers 31 cooperate with the clamping plates 32 to reduce the clamping force. After the torque sensor 4 is clamped and positioned, a torque rod 42 can be inserted into the torque input end 41 of the torque sensor 4, and the torque sensor 4 can be detected by twisting the torque rod 42.

[0030] A specific application of this embodiment is as follows: By setting a fixing mechanism 2, under the limitation of the sliding rail 24, the two racks 25 can only slide left and right within the housing 1. When the motor 21 starts, it drives the rotating rod 22 inside the housing 1 to rotate. The rotating rod 22 drives the gear 23 to rotate. When the gear 23 rotates, it drives the racks 25 connected to the upper and lower parts to move away from each other or move closer to each other. With the cooperation of the two sliding rods 26, when the two racks 25 move away from each other, they drive the two hinge blocks 27 to move, so that the hinge rod 29 rotates on the outer wall of the rotating shaft 292, so that the hinge blocks 294 on the two rotating shafts 293 move closer to each other, so that the two hinge blocks 294 drive the two sliding rods 295 to move towards the torque sensor 4 at the same time, so that the torque sensor 4 can be positioned at the top center of the housing 1, realizing the precise positioning of the torque sensor 4.

[0031] With the buffer mechanism 3 in place, when the two slide bars 295 approach each other, they will drive the two clamping plates 32 to approach the torque sensor 4. After the clamping plates 32 contact the torque sensor 4, the position of the torque sensor 4 can be fixed to prevent the torque sensor 4 from shaking during the detection process. The two dampers 31 cooperate with the clamping plates 32 to reduce the clamping force and prevent excessive clamping force from damaging the torque sensor 4, thereby further improving the stability of the whole device during the detection process. After clamping and positioning the torque sensor 4, a torque rod 42 can be inserted into the torque input end 41 of the torque sensor 4, and the torque sensor 4 can be detected by twisting the torque rod 42.
