However, during transportation, the lifting mechanism, due to its considerable length, typically occupies a significant amount of space. Therefore, a new type of benchtop material testing machine for measuring material properties is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the problem that current torque testing machines generally have a lifting mechanism on their surface to accommodate different test objects of varying lengths, but during transportation, the lifting mechanism, due to its long length, typically occupies a significant amount of space.

[0007] A rotating disk is provided above the base, and the base also includes a second drive unit, two clamping units respectively disposed on the surfaces of the sliding plate and the rotating disk, and a measuring unit. The second drive unit is used to drive the rotating disk to rotate, the two clamping units are used to clamp the object to be tested, and the measuring unit is used to detect the change in resistance encountered by the rotating disk during rotation.

[0008] Furthermore, the base includes a mounting base, and a mounting plate is provided above the mounting base.

[0010] Furthermore, the mounting unit includes two mounting protrusions respectively disposed at one end of the two empty tubes. The surfaces of the two mounting protrusions are slidably inserted into the surface of the mounting plate, and externally threaded tubes are threaded into the surfaces of the two mounting protrusions. Internally threaded tubes are threaded onto the surfaces of the two externally threaded tubes.

[0011] Furthermore, the second drive unit includes a drive disk that is rotatably inserted into the surface of the mounting plate.

[0015] 1. In this utility model, two hollow tubes are set above the base, and the same slide plate is slidably inserted into the inner wall of the two hollow tubes. In use, the user needs to clamp both ends of the object through the clamping unit, and then drive the rotating disk to rotate through the second drive unit, which further drives one end of the object to be detected to rotate.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] This embodiment provides a benchtop material testing machine, mainly to address the problem that current torque testing machines typically have a lifting mechanism on their surface to accommodate different test object lengths. However, during transportation, this lifting mechanism, due to its considerable length, often occupies a significant amount of space. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0025] A benchtop material testing machine includes: a base 1 with two hollow tubes 2 mounted on top, and a sliding plate 3 slidably inserted into the inner wall of the two hollow tubes 2. In use, the user controls the sliding plate 3 to slide along the inner wall of the two hollow tubes 2 via a first drive unit 4, which moves a clamping unit 8 located below the sliding plate 3 to accommodate objects of different lengths. Since a rotating disk 6 is mounted above the base 1, the user clamps one end of the object to be tested using another clamping unit 8 located on the surface of the rotating disk 6. Then, the user drives the rotating disk 6 to rotate via a second drive unit 7, causing the object to be tested to rotate. The detection unit detects the resistance experienced by the rotating disk 6 during rotation (this resistance remains relatively constant because the other end of the object to be tested is not clamped, and the object does not receive torque). Then, the user clamps the other end of the object to be tested using the clamping unit 8 on the surface of the sliding plate 3, and controls the rotating disk 6 to rotate via the second drive unit 7. The detection unit detects the change in resistance experienced by the rotating disk 6 during rotation. Subtracting the previously detected resistance from this change in resistance yields the magnitude of the torque.The main components of the base 1 are: a mounting base 11 with a mounting plate 12 on top; in use, the user inserts several mounting bolts 13 into the surface of the mounting plate 12, so that the surfaces of the mounting bolts 13 are all threaded into the surface of the mounting base 11, thus mounting the mounting plate 12 on top of the mounting base 11; and the main components of the first drive unit 4 are: a guide tube 42 fixedly installed on the inner wall of one of the hollow tubes 2, and a drive threaded rod 41 rotatably inserted into the inner wall of the other hollow tube 2. In use, the user controls the output end of the first motor 43 fixedly installed on the surface of the other hollow tube 2 to rotate through the controller 44 fixedly installed on the surface of the mounting base 11, thus driving the drive threaded rod 41 to rotate at the other end of the hollow tube 2. The inner wall of pipe 2 slides, further driving the threaded sleeve to engage with the surface of the drive threaded rod 41, and the sliding plate 3, which is slidably engaged with the surface of the guide tube 42, to rise and fall. The main components of the mounting unit 5 are: two mounting protrusions 51 respectively set at one end of the two empty pipes 2. In use, the user inserts the surfaces of the two mounting protrusions 51 into the surface of the mounting plate 12, and then threads the internal threaded tubes 53 onto the surfaces of the two external threaded tubes 52 respectively fixedly installed on the surfaces of the two mounting protrusions 51, thereby limiting the two empty pipes 2 above the mounting plate 12. The main components of the second drive unit 7 are: a drive disk 71 rotatably inserted into the surface of the mounting plate 12. In use, the user rotates and inserts several fixing bolts 72 into the surface of the rotating disk 6. The surfaces of several fixing bolts 72 are threaded into the surface of the drive disk 71. Finally, the output end of the second motor 73, which is fixedly installed on the surface of the mounting plate 12, rotates, thereby rotating the drive disk 71, which is fixedly installed on the output end of the second motor 73, and further driving the rotating disk 6. The main components of the two clamping units 8 are: two clamping slots 81 respectively opened on the surface of the mounting plate 12 and the slide plate 3. In use, the user places both ends of the object to be tested on the inner walls of the two clamping slots 81 respectively, and then rotates several clamping threaded rods 83, which are respectively threaded into the inner walls of the two clamping slots 81. This drives several clamping plates 82, which are respectively rotated and sleeved on the surfaces of the clamping threaded rods 83, to rotate on both sides. The inner wall of the clamping groove 81 slides, thereby driving several clamping plates 82 to clamp and fix the two ends of the object to be tested in pairs. The main components of the measuring unit 9 are: several slots 92, each set on the inner wall of the rotating disk 6. In use, when the user controls the output end of the second motor 73 to rotate through the controller 44, several measuring protrusions 91, each set on the surface of the drive disk 71, will abut against the surfaces of several pressure sensors 93, each set on the inner wall of several slots 92 (the surfaces of several measuring protrusions 91 are slidably inserted into the inner wall of several slots 92), thereby realizing the detection of the change in resistance encountered by the rotating disk 6 during rotation (the several pressure sensors 93 transmit the relevant data to the controller 44).

[0026] By setting two hollow tubes 2 above the base 1, and slidably inserting the same slide plate 3 into the inner wall of the two hollow tubes 2, the user needs to clamp both ends of the object through the clamping unit 8 during use, and then drive the rotating disk 6 to rotate through the second drive unit 7, which further drives one end of the object to be detected to rotate. The detection unit can detect the change of resistance encountered by the rotating disk 6 during rotation, thereby realizing the detection of torque. Before this, the user can control the spatial height of the slide plate 3 through the first drive unit 4 to adapt to different object lengths. During transportation, the user can remove the two hollow tubes 2 through the installation unit 5 for transportation, thereby saving some transportation space.

[0027] By setting several measuring protrusions 91 on the surface of the drive disk 71 and opening several slots 92 on the inner wall of the rotating disk 6, the user needs to clamp the object on the surface of the rotating disk 6 (the clamping unit 8 on the surface of the slide plate 3 does not clamp the object) during use. The controller 44 controls the output end of the second motor 73 to rotate, which will drive the several measuring protrusions 91 to contact the surfaces of several pressure sensors 93 respectively. The data detected by the pressure sensors 93 when no torque is applied to the object to be detected is detected. Finally, the other end of the object is clamped on the surface of the slide plate 3, and the controller 44 controls the output end of the second motor 73 to rotate. The torque and torque change of the object to be detected can be obtained by subtracting the previous data from the force detected by the pressure sensor 93 (displayed on the display screen of the controller 44).

[0028] The working process of this utility model is as follows: First, the user needs to place the object on the inner wall of the clamping groove 81 on the surface of the mounting plate 12, rotate one of the clamping threaded rods 83, and drive the two clamping plates 82 to move closer together to clamp one end of the object to be tested (the clamping unit 8 on the surface of the slide plate 3 does not clamp the object). Then, the controller 44 controls the output end of the second motor 73 to rotate, which will drive several measuring protrusions 91 to abut against the surfaces of several pressure sensors 93 respectively, and detect the data detected by the pressure sensors 93 when no torque is applied to the object to be tested. Finally, clamp the other end of the object on the surface of the slide plate 3, and then control the output end of the second motor 73 to rotate again through the controller 44. The torque and torque change of the object to be tested can be obtained by subtracting the previous data from the force detected by the pressure sensor 93 (displayed on the display screen of the controller 44).

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
