Super large torque standard machine balance arm pull rod linkage lifting control mechanism

Abstract

The invention relates to an ultra-large torque standard machine balance arm pull rod linkage lifting control mechanism, which has a balance arm for balancing the standard arm, two standard weights for leveling the standard arm, and two standard weight arms. Each side is connected to a hook through a rotating pair. During the process of leveling the standard arm, the standard weight on one side of the standard arm is connected to the hook, and the standard weight on the other side is disconnected from the hook, and the hook is connected to the standard weight. The position of the code center of gravity is located on the same vertical line; each side of the balance arm is connected to a pull rod through a rotating pair, and the standard moment arm is connected to the balance arm through a connecting rod. The invention solves the problem of leveling the standard force arm with super large torque, and the lifting speed of the pull rod can be automatically adjusted according to the on-site working conditions, which not only avoids the overshoot phenomenon caused by too fast speed, but also improves the working efficiency. The invention can realize the function of bidirectional measurement of single tooling, improve work efficiency and save labor cost.

Description

technical field [0001] The invention relates to a measurement detection, torque detection calibration, and torque testing device, in particular to a balance arm pull rod linkage lifting control mechanism of a super large torque standard machine. Background technique [0002] The ultra-large torque standard machine is a high-precision torque measurement equipment. Such equipment is usually composed of standard weights and standard moment arms. When in use, the standard weight is hung on the standard force arm, and the standard force arm is adjusted to a horizontal position at the same time. The weight naturally sags under the influence of gravity, so the product of the mass of the weight and the length of the force arm forms a standard torque value, which is applied to On the sensor under test, the torque sensor under test can be measured. Therefore, the leveling of the standard moment arm is very important for the ultra-large knife-edge torque standard machine, which affec...
