Problems solved by technology

[0004] In order to solve the problems of low precision and poor field operation practicability existing in the current torque flange calibration method, the present invention provides a new torque flange calibration device, which uses two parallel calibration arms to reduce the number of external devices that provide reverse thrust. The device loads the weight on two different calibration arms, and the length of each calibration arm is 50% shorter than that of the common calibration arm with the same range, which requires less space for calibration. error, improve the calibration accuracy of the torque flange

Embodiment Construction

[0027] The present invention will be further described below in conjunction with specific embodiments.

[0028] from figure 1 It can be seen that the torque flange calibration device in this embodiment is mainly composed of an adjustment weight 1, an upper arm support 2, an upper arm 3, an upper arm weight support 5, an upper arm weight tray 6, and a lower arm weight support 8. The lower arm weight tray 9, the lower arm 10, the lower arm adjustment block strut 14, the adjustment block 15, and the upper arm adjustment block strut 16 are composed. Wherein the upper arm 3 and the lower arm 10 can be telescopic arms, and the length of the arms can be adjusted according to different amounts of stroke torque flanges. The axial center of the lower arm 10 is provided with a torque flange adapter 11. It can also be understood that the lower arm 10 is two equal-length arms, and the two equal-length arms are respectively welded on the torque flange adapter 11. on both sides. The struc...

Abstract

The invention relates to a torque flange calibration device, which solves the problems of low precision and poor field operation practicability of a torque flange calibration mode, and comprises an adjusting weight, an upper arm lever bracket, an upper arm lever, a lower arm lever, an arm lever adjusting assembly, an upper arm lever weight support rod and a lower arm lever weight support rod, wherein the upper arm rod is hinged with the upper arm rod bracket; the two ends of the upper arm rod are fixedly connected with one end of the upper arm rod weight supporting rod and one end of the arm rod adjusting assembly respectively; a torque flange adapter is arranged in the axial center of the lower arm rod; and the two ends of the lower arm rod are fixedly connected with the lower arm rod weight supporting rod and the other end of the arm rod adjusting assembly respectively; the arm rod adjusting assembly adjusts the upper arm rod and the lower arm rod to be parallel to each other; the end parts of the upper arm lever weight supporting rod and the lower arm lever weight supporting rod are used for placing calibration weights, and applying vertical downward force to the upper arm rod and the lower arm rod; and the weight of the arm rod adjusting assembly is equal to the sum of the weights of the upper arm rod weight supporting rod and the lower arm rod weight supporting rod. The method has low requirements on calibration space, reduces a weight lifting device, and is low in cost.

Description

technical field [0001] The invention relates to a torque calibration device, in particular to a torque flange calibration device. Background technique [0002] The torque flange (that is, the torque sensor) has a wide range of application scenarios, and its measurement accuracy directly affects the test results and affects the objective evaluation of product performance. Therefore, it is necessary to calibrate the measurement accuracy of the torque flange to meet product testing requirements. [0003] At present, there are two commonly used calibration methods for torque flanges: one is the calibration method using cylinder loading, which needs to calibrate the cylinder force sensor, and there are system errors that are difficult to eliminate, thus affecting the calibration accuracy of torque flanges; The second is to use a long arm for calibration. When calibrating a torque flange with a large range, the length of the arm is 6m to 10m, so the stiffness of the long arm canno...
