Problems solved by technology

However, the above method requires high installation accuracy, which requires that the force applied to the lever must be perpendicular to the lever adjustment
In this way, it is difficult to debug, and because of the installation space requirements, some usage occasions cannot meet

Embodiment approach

[0024] The torque calibrating disk 10 forms a balanced disc moment arm, and the torsion calibrating disk 10 includes two semi-disc structural members 11, and the ends of the two semi-disc structural members 11 are fixedly connected. As an embodiment, the semi-disc structure 11 is a semi-circular structure, so that two semi-circular structure semi-disc structures 11 are connected to form a circular torsion calibration disc.

[0025] The shaft locking mechanism 20 is used to fix the torque calibration device of the present invention to the shaft 200 of the system under test, and transmit the torque of the torque calibration disk 10 to the shaft under test. The shaft locking mechanism 20 can be A cylindrical structure, the cylindrical shaft locking mechanism 20 is arranged coaxially with the torque calibrating disk 10 .

[0026] Further, the shaft locking mechanism 20 has a locking position, and the locking position is located at the center of the circle of the torque calibration...

Abstract

The invention provides a torsion calibration device which comprises a torsion calibration disk, a shaft locking mechanism, a gravity line and a balance weight, wherein the torsion calibration disk comprises two semicircular disk structural parts; end parts of the two semicircular disk structural parts are firmly connected; the shaft locking mechanism comprises a locking position; the locking position is located at a circle center of the torsion calibration disk; and the shaft locking mechanism is firmly connected to the torsion calibration disk by a connecting part and can move synchronously with the torsion calibration disk; and one end of the gravity line is firmly connected to an external arc face of the torsion calibration disk and is kept tangent to the external arc face, and the other end of the gravity line is firmly connected to the balance weight. The torsion calibration device provided by the invention has the advantages of simple structure, low cost, convenient installation and debugging and simple operation. Meanwhile, a target component does not need to be dismounted for testing and online testing can be carried out directly under usual conditions. In addition, the torsion calibration device provided by the invention has pure mechanical structure, a long service life and stable performance.

Description

technical field [0001] The invention relates to a calibrating device, in particular to a torsion calibrating device. Background technique [0002] With the advent of the industry 4.0 era, the application of robots, robot arms, and torque testers is increasing rapidly. Therefore, it is of great significance to calibrate the comprehensive torque transmission capability and torque test accuracy of robots, robot arms, and torque testers. [0003] In view of the above problems, the current existing torque calibration schemes are mainly: [0004] 1. Use a torque tester for torque calibration. However, the torque tester is large in size and heavy in weight, and cannot be directly installed on the system under test for testing, and can only test the components of the torque transmission separately. Therefore, the above method is complicated to operate, and cannot fully reflect the capability and precision of the entire transmission system. At the same time, due to the large volum...
