[0002] The fully automatic torque testing machine is a specialized device for testing the torsional mechanical properties of materials or components. It can determine the torque, torsion angle, and life characteristics of products such as torsion springs, shafts, and transmissions. It is widely used in hardware, electronics, automotive, aerospace and other fields, and supports tests such as torsional failure and shear modulus of metallic / non-metallic materials and parts.

[0003] In existing technologies, when measuring torque, both the upper and lower ends are fixed, which can cause a pulling phenomenon and make the torque measurement inaccurate. If an electric control device is added above or below, but synchronous operation cannot be achieved, it will also lead to inaccurate torque measurement. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0017] Reference Figures 1-7 A fully automatic torque testing machine includes: a machine body 1 and four feet 6 located at the bottom corners of the machine body 1. When the machine body 1 is placed on a platform and wobbles, the height of the feet 6 can be adjusted to ensure the machine body 1 can perform testing in a stable environment. An operation panel 5 is located on the front side of the machine body 1. Two connecting columns 2 are fixedly connected to the top of the machine body 1, and the two connecting columns 2 are equipped with vertical adjustment devices 7. A load cell fixing seat 4 is located at the bottom of the vertical adjustment device 7. This fixing seat is used to fix the load cell. Please note the following when fixing. The load cell should be level both horizontally and horizontally to avoid affecting the accuracy of the test due to any tilt angle. The load cell is located at the bottom of the load cell mounting base 4. The load cell is a device used to detect the test force during the test. Note that each load cell has its maximum load capacity marked on its surface. Although this machine has an overload protection function, it is still recommended not to exceed its capacity to avoid damage to the load cell. A loading platform 3 is located at the top center of the machine body 1. The loading platform 3 is used to place the rotating shaft waiting to be tested or related fixtures 12 to facilitate clamping the finished product for testing. A fixing mechanism is installed on the top of the machine body 1; The protective mechanism is located inside the machine body 1.

[0018] Reference Figure 1 and Figure 2 The up-down adjustment device 7 includes a movable seat 23 slidably disposed on the outer surface of two connecting columns 2. Two auxiliary pulleys 8 are rotatably disposed on the top of the movable seat 23. Steel wire ropes are wound and connected to the two auxiliary pulleys 8. The two ends of the steel wire ropes are respectively fixedly connected to a counterweight 9 and a fixture 12 through the two auxiliary pulleys 8. Guide rails 10 are provided on both the front and rear sides of the movable seat 23. A counterweight 11 is provided on the front side of the movable seat 23. The steel wire ropes form a closed loop system, with one end connected to the fixture 12 and the other end connected to the counterweight 9. The direction is changed through the two auxiliary pulleys 8 in the middle. The force is distributed by changing the number of segments of the steel wire rope, such as the force-saving principle of movable pulleys.

[0019] Reference Figure 3 The foot base 6 includes bolts 13 rotatably disposed at the four corners of the bottom of the machine body 1. The bolts 13 are internally threaded with screws 14, which are slidably connected to the machine body 1. Support feet 15 are fixedly connected to the bottom of screws 14.

[0020] Reference Figure 1 The fixing mechanism includes a placement platform rotatably mounted on the top of the loading platform 3. A motor is installed inside the loading platform 3. The output shaft of the motor is fixedly connected to the placement platform. A slide groove 16 is fixedly installed on the top of the placement platform. Two clamping plates 19 are slidably connected in the slide groove 16. Fixing blocks 18 are fixedly connected to the left and right sides of the top of the loading platform 3. A screw 24 is rotatably connected to the side of the two clamping plates 19 that is far apart from each other. The two screws 24 are threadedly connected to the two fixing blocks 18 respectively. A knob 17 is fixedly connected to the side of the two screws 24 that is far apart from each other.

[0021] Reference Figure 7 The protective mechanism includes a hydraulic cylinder 20 located on the bottom side inside the machine body 1. The output end of the hydraulic cylinder 20 is fixedly connected to a cross-shaped connecting plate 21. Protective plates 22 are fixedly connected to all four sides of the cross-shaped connecting plate 21. The four protective plates 22 are slidably connected to the machine body 1.

[0022] The implementation principle of a fully automatic torque testing machine in this application embodiment is as follows: By manually rotating the bolt 13, the bolt 13 can drive the screw 14 and the support foot 15 to move upward, which can adapt to different ground heights. Then, the object to be tested is placed on the loading platform 3. By manually rotating the knob 17, which is threadedly connected to the fixing block 18, the two clamping plates 19 can be driven to move closer to each other to fix the object to be tested. The steel wire rope connects the fixture 12 and the counterweight 9 via two auxiliary pulleys 8 at the top, forming a mechanical balance structure. When the weight of the object being tested changes, the system balance is maintained by precisely adjusting the addition or subtraction of standard weights. During the test, the motor drives the object being tested to generate a torsion, and the fixture 12 moves synchronously along the Z-axis guide rail 10. The torque generated by the reverse displacement of the counterweight 9 cancels out the influence of height changes in real time, ensuring that the fixture 12 and the object being tested always maintain vertical contact and that the object is not pulled during the torsion process. Example 2

[0023] The difference between this embodiment and Embodiment 1 is that: anti-slip threads are provided on the outer surface of the knob 17 to increase the friction when the knob is rotated, prevent slippage during manual rotation of the knob, and further improve the stability and reliability of fixing the object to be tested.

[0024] 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.
