Description

Technical Field

[0001] The utility model relates to the technical field of physical torque force measuring devices, and more specifically, to a physical torque force measuring device. Background Art

[0002] In the existing technology, physical torque force measurement devices are important equipment for measuring torque and force in mechanical systems. However, during use, the transmission end of these devices is usually fixed by a chuck. A chuck is a clamping device that generates clamping force mechanically or hydraulically to fix and maintain the stability of the workpiece. This fixing method is common and effective at the transmission end because it ensures that the measured shaft or component will not move relative to each other during the measurement process, thereby ensuring the accuracy of the measurement results.

[0003] However, when it comes to the fixed end, if the chuck is still used for fixing, it may cause some inconvenience. The fixed end usually refers to the part of the measuring device that is not directly involved in the torque transmission, such as the supporting structure or frame of the equipment. Using a chuck to fix the fixed end may cause some problems. First of all, the installation and adjustment of the chuck may require relatively complicated operations, including adjusting the clamping force, ensuring the concentricity of the chuck and the measured shaft, etc. These operations not only require a certain degree of technical proficiency, but may also take a lot of time, thus reducing the convenience of operation of the equipment.

[0004] Secondly, the fixing method of the chuck may not be suitable for the characteristics of the fixed end in some cases. For example, if the fixed end is large in size or has a complex shape, it may be difficult to find a suitable chuck or adapter. In addition, the clamping force of the chuck may cause additional stress on the structure of the fixed end, especially when measuring high torque, this stress may cause deformation or damage to the fixed end.

[0030] In this embodiment, when the corresponding parts need to be measured, one end is first clamped on the chuck 25, and the other end is inserted into the fixed groove 9, and then the slides 15 on the multiple follower blocks 5 are driven to slide along the reducing groove 10, so that the spring 7 is pressed against the parts. Therefore, the spring 7 can drive the follower block 5 to move when the part rotates, and then with the compression of the spring 7, the follower block 5 is clamped on the part, thereby ensuring the clamping process. When the elastic force of the spring 7 needs to be adjusted, the fixing bolts 12 between the upper ends are pressed against the corresponding middle plate 8, so that the stiffness coefficient of the spring 7 can be changed, so that the elastic force of the spring 7 can be adjusted, thereby ensuring the follow-up effect.
