Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a torque testing bench. Background Technology

[0002] Valves play a crucial role in pipeline systems, controlling the flow of various types of fluids such as air, water, steam, corrosive media, oil, radioactive media, mud, and liquid metals. They also control the flow rate and pressure of the pipeline. If a valve malfunctions, it can cause fluid leakage in the pipeline, resulting in economic and personnel losses. Torque testing is an important means of measuring the valve's closing and opening torque, and it can be used to determine the valve's quality, performance, and reliability.

[0003] The existing technical solutions mentioned above have the following drawbacks: Traditional torque test benches adjust the braking force of the brake by using oil pipes and reversing valves. However, the reversing valves are often in manual mode, and manual reversing relies on manual adjustment, which will cause deviations in braking force. Therefore, the torque force obtained has a large error. At the same time, it is labor-intensive and time-consuming, and the degree of automation is too low, which affects the testing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a torque testing bench to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A torque testing bench includes a support. A first rectangular plate is fixedly mounted on the left end of the support. The top of the first rectangular plate has a first rectangular hole that extends from left to right. Second rectangular holes are symmetrically arranged on the left end face of the first rectangular plate. A slider is slidably mounted in the second rectangular holes. A rotating module is fixedly mounted on the left side of the slider. A limiter is fixedly mounted on the bottom end of the first rectangular plate, with the axis of the limiter vertically aligned. A first mounting plate is fixedly mounted on the top of the support. The other end of the first mounting plate extends to the left side of the support. A first circular hole extends vertically through the top left end of the first mounting plate, with the axis of the first circular hole vertically aligned. A cylinder is fixedly mounted on the top of the first mounting plate. The other end of the cylinder extends downward to connect with the rotating module. The axis of the cylinder is collinear with the axis of the first circular hole.

[0007] By adopting the above technical solution, it can be ensured that the driving force applied by the cylinder to the rotating module is axial, and the height of the rotating module can be controlled by the cylinder to adapt to different working conditions.

[0008] In a further embodiment, the rotating module comprises a housing, guide rails, tracks, a second mounting plate, a rotating shaft, a belt, a drive motor, and a torque sensor. The top of the housing has an integrally formed annular protrusion with its axis vertically aligned. The annular protrusion is fixedly connected to the bottom of the cylinder. The left end face of the housing is completely open. The bottom of the housing has a second through-hole with its axis vertically aligned. The housing is fixedly mounted on the left side of the bracket, with its left end face fitting against the right end face of the bracket.

The axis of the drive motor is vertically oriented, and a driving gear is rotatably mounted on the top of the drive motor, and the axis of the driving gear is collinear with the axis of the drive motor. A belt is wrapped around the circumference of the driving gear, and the other end of the belt is wrapped around the circumference of the driven gear. The driving gear drives the belt to rotate, which in turn drives the driven gear to rotate.

[0009] By adopting the above technical solution, the driving gear drives the driven gear to rotate through the belt, which can realize the non-rigid connection transmission between the two gears. The rotation of the drive motor can drive the rotating shaft to rotate.

[0011] By adopting the above technical solution, the torque sensor can obtain torque data more accurately, and the flange setting can protect the shaft.

[0012] In a further embodiment, a chuck is fixedly mounted at the bottom of the rotating shaft, and the top of the chuck is rotatably mounted inside a fourth flange.

[0013] By adopting the above technical solution, the chuck can be configured to be suitable for different valves.

[0014] In a further embodiment, a limiter is fixedly installed on the top of the second mounting plate, and the axis of the limiter is vertically arranged.

A base is fixedly installed at the bottom of the threaded rod.

[0017] By adopting the above technical solution, the test stand can be made more stable and robust during operation.

[0018] In summary, this utility model has the following beneficial effects:
