Problems solved by technology

The feature of this device is that it can be taken to the scene to detect the four-wheel aligner. The disadvantage is that the measurement accuracy is affected by the processing technology of the screw rod and the wear and tear of the use.
[0004] The second type of four-wheel aligner verification device is a verification device that truly simulates the four-wheel alignment relationship. It truly reflects the parameters of the wheel toe, wheel camber, and main shaft caster angle, and has a high detection accuracy (the detection accuracy is 0.5 ’, and the first type is 1’), which can be used to test different types of four-wheel aligners, but it also has disadvantages: it has high requirements on environmental conditions, and the environmental conditions on site generally do not meet the verification requirements; in addition, the device is relatively heavy. , the structure is complex, and it is impossible to move it to the verification site for use; it cannot meet the needs of the measurement department for on-site verification / calibration of the four-wheel aligner
Then after a long time of use, or when the environment changes slightly, or after being moved, the accuracy of the device will be affected to varying degrees
Unable to meet the needs of the measurement department for on-site inspection of the four-wheel aligner

Abstract

The invention discloses a standard of an angle measurer. The standard comprises a rotating device and a control system, and is characterized in that: the rotating device is a double-shaft mechanical rotating device and comprises a direction and position rotary axis system and a pitch rotary axis system which are interconnected and vertical, wherein each rotary axis system is provided with an electromagnetic locking device, an angular contact bearing, a permanent-magnetic direct-current torque motor and an angle measuring element; the direction and position rotary axis system is connected with a worktable top used for placing an apparatus to be detected; and the angle measuring element of each rotary axis system forms an angle measuring system. The standard adopts the technology of combining low-speed large-torque driving technology, automatic control technology, precise measuring technology, touch screen artificial intelligent technology and programmable logic controller (PLC), so standard angle technology with high precision and high load, which can output at any angle, is realized, and a plurality of types of angle measurers, such as various wheel positioning apparatuses, are subjected to metrological verification / calibration.

Description

technical field [0001] The invention relates to the technical field of standard devices for verification / calibration of angle measuring instruments, in particular to a wide-angle standard angle with load capacity, which is suitable for on-site verification / calibration of angle measuring device standards for wheel aligners. Background technique [0002] The wide-angle standard angle with load force can output high-precision standard angle with load force at any angle. It is mainly used for the verification / calibration of various types of angle measuring instruments by legal metrology and inspection institutions, production enterprises and scientific research institutes. Automobile manufacturers use the most angle measuring instruments, including automobile four-wheel aligners, front wheel aligners, motor vehicle steering wheel steering angle detectors, and automobile steering angle inspection benches. At present, the verification / calibration standards that are relatively form...
