Description

Technical Field

[0001] This application relates to the field of torque testing machine technology, and in particular to torque testing machines. Background Technology

[0002] A torque tester is a device used to measure the mechanical properties of materials or components under torque. By applying torque and measuring deformation or fracture points, it evaluates characteristics such as torsional strength, stiffness, and durability. It is widely used in manufacturing, automotive, aerospace, and materials research to test the performance of components such as fasteners and drive shafts. Torque testers are available in manual, automatic, and digital types, offering advantages such as high precision, multifunctionality, and data logging, ensuring the reliability of materials and components in practical applications.

[0003] When conducting torque tests on large products, existing fixtures cannot be well adapted to the products, resulting in the products being loosely clamped. Furthermore, the large weight and inertia of large products make them prone to vibration and shaking during the test, affecting the test accuracy. Utility Model Content

[0013] In summary, this application includes at least the following beneficial technical effects of the torque testing machine:

[0014] 1. The turntable is mounted on the frame, and the product under test is mounted on the frame. The positioning component positions the product under test. After the product under test is positioned, it is connected to the turntable. In use, the drive component drives the turntable to rotate.

[0022] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a torque testing machine.

[0025] Reference Figure 1 A torque testing machine includes a frame 1, on which a turntable 2 is rotatably mounted. In use, the product to be tested is connected to the turntable 2. A torque sensor 3 is installed on the frame 1 to detect the torque generated by the turntable 2. A drive assembly 4 and a positioning assembly 5 are also installed on the frame 1. The positioning assembly 5 positions the product to be tested on the frame 1, and then the drive assembly 4 drives the turntable 2 to rotate.

[0026] Reference Figure 2 The turntable 2 is rotatably mounted on the frame 1. To improve the ease of rotation of the turntable 2 on the frame 1, the drive assembly 4 includes a drive motor 41 and a connecting shaft 42. The drive motor 41 is mounted on the frame 1, and a drive wheel 43 is provided on the output shaft of the drive motor 41. The connecting shaft 42 is rotatably mounted on the frame 1, and a driven wheel 44 is provided at one end of the connecting shaft 42. A transmission chain 45 is sleeved between the drive wheel 43 and the driven wheel 44. The closed loop structure of the transmission chain 45 is configured to continuously transmit power between the drive wheel 43 and the driven wheel 44. In use, the drive motor 41 drives the drive wheel 43 to rotate, and the drive wheel 43 drives the driven wheel 44 to rotate through the transmission chain 45. This reduces the rotational speed of the connecting shaft 42 driven by the driven wheel 44 and increases the rotational torque of the connecting shaft 42.

[0027] A coupling 46 is provided between one end of the connecting shaft 42 and the torque sensor 3, and the coupling 46 connects the connecting shaft 42 and the torque sensor 3. Furthermore, in order to reduce the torque generated by the connecting shaft 42 on the torque sensor 3, a bearing seat 47 is provided on the frame 1. The bearing seat 47 is mounted on the frame 1, and the connecting shaft 42 passes through the bearing seat 47, thereby protecting the torque sensor 3.

[0028] Reference Figure 3 When testing products, some of them are quite heavy. To reduce the pressure exerted on the turntable 2, support rods 21 are installed on the turntable 2. Four support rods 21 are spaced apart on the side of the turntable 2 closest to the frame 1. One end of each support rod 21 is connected to the turntable 2, and the other end extends towards the frame 1. Support wheels 22 are rotatably mounted on the ends of the four support rods 21 closest to the frame 1. The support wheels 22 press against the frame 1. When the turntable 2 rotates, the support wheels 22 on the support rods 21 press against the frame 1. In use, the support rods 21 and support wheels 22 support the turntable 2, thereby reducing the pressure on the turntable 2 and improving its rotation efficiency.

[0029] Furthermore, in order to enable the turntable 2 to drive the product under test to rotate, the turntable 2 is provided with positioning holes 23. Several positioning holes 23 are evenly spaced around the turntable 2. The turntable 2 is provided with positioning pins 24. When in use, one end of the positioning pin 24 passes through the product under test and is inserted into the positioning pin 24 of the turntable 2, so that the turntable 2 can drive the product to rotate when it rotates.

[0030] In addition, in order to improve the stability of the product under test on the rack 1, two sets of positioning components 5 are arranged at intervals on the rack 1. The two sets of positioning components 5 have the same structure and function, so only one set of positioning components 5 will be described below.

[0031] Reference Figure 4 The positioning component 5 includes a screw 51, which is rotatably mounted on the frame 1. A handwheel 52 is provided on the frame 1 and connected to the screw 51. In use, the handwheel 52 drives the screw 51 to rotate on the frame 1. A clamping plate 53 is provided on the frame 1, positioned opposite to the corresponding screw 51. One end of the screw 51 passes through both clamping plates 53 in sequence, and the screw 51 is threadedly connected to both clamping plates 53. In use, rotating the screw 51 via the handwheel 52 causes the two clamping plates 53 to move closer to or further away from each other.

[0032] After the product to be tested is placed between the two clamping plates 53, turning the handwheel 52 moves the clamping plates 53 closer together. Furthermore, to improve the stability of the product on the frame 1, support plates 54 are provided on the sides of the two clamping plates 53 that are close to each other. The support plates 54 are bolted to the clamping plates 53. Additionally, support blocks 55 are integrally formed with the support plates 54. When the two clamping plates 53 clamp the product to be tested, the support blocks 55 support the product. This reduces the weight of the product on the turntable 2, allowing the turntable 2 to rotate normally on the frame 1.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
