Abstract
Description
A device for detecting the torque of a flange single nut Technical Field
[0001] This utility model belongs to the field of torque detection technology and relates to a torque value detection device for a flange single nut. Background Technology
[0002] In existing flange single nut torque testing devices, traditional testing devices may lack precise positioning and support during operation, resulting in unstable and inaccurate measurement results. When dealing with lead screws of different lengths, these devices usually lack a convenient and effective installation method, which not only increases the complexity of operation but may also affect the accuracy of measurement.
[0003] However, most devices on the market are inconvenient to adjust when dealing with lead screws of different sizes, and their support structures are simple, which makes it impossible to achieve ideal stability and measurement accuracy. In addition, the stability of the lead screw in the rotation state is also a key factor affecting the measurement accuracy. Some current devices sometimes experience lead screw loosening or deviation when the lead screw rotates, which affects the test results. Summary of the Invention

[0012] The torque detection device for a flange single nut provided in this embodiment of the utility model has the following advantages:
[0013] 1. The torque detection device for a flange single nut uses a lead screw fixed to a left and right side plate on a base plate. A motor on the left side plate drives the lead screw to rotate, while a support assembly on the right side plate provides stability, ensuring the lead screw's position does not shift during rotation. A movable flange single nut is screwed onto the lead screw and connected via a spring scale, allowing for accurate measurement of the torque generated when the flange single nut is rotated. To further improve measurement accuracy, the device includes first and second sliders on a guide rail, as well as first and second support rods. The first support rod enhances the stability of the lead screw, while the second support rod, under the action of a second bolt, can be adjusted in angle for easy positioning and fixing of the flange single nut. Furthermore, the support rod in the support assembly features a ball bearing design, providing additional support to the lead screw through contact with a second concave hole within the lead screw, accommodating lead screws of different lengths. During this process, a spring between the slider and the support rod maintains the accuracy and stability of the spring scale, ensuring accurate and stable results when detecting the preload torque of the lead screw.

[0023] Preferably, the base plate 1 is provided with a guide rail 2, the guide rail 2 is slidably provided with a second slider 4, the second slider 4 is hinged with a second support rod 41, the upper end of the second support rod 41 is provided with a support concave plate 42, the inner concave plate 42 is supported by the flange single nut 14, and the flange single nut 14 is fixed to the support concave plate 42 under the fixing of the second bolt 43.
[0024] When the second support rod 41 is rotated, the angle of the support concave plate 42 changes, making it easier to move the concave part of the support concave plate 42 to the flange single nut 14. At this time, the edge of the flange single nut 14 is located in the concave part of the concave plate 42. With the rotation of the second bolt 43, the flange single nut 14 is fixed to the concave plate 42, so that the flange single nut 14 is fixed on the screw 13 and can move to facilitate the measurement of the torque value.

[0027] Preferably, the rotating assembly 6 includes a motor 61, a rotating shaft 62, a first thread 63, a first through hole 64, a fixing block 65, a second through hole 66, a push ring 67, a push rod 68, a push plate 69, and a fixing ring 70; the motor 61 is mounted on the left side plate 11, and the output end of the motor 61 is mounted on the rotating shaft 62.
