[0002] FK auxiliary switch is an electrical switch often used in the field of high-voltage operating mechanisms. As a chain effect of high-voltage control signals, it is related to the operation, safety and stability of the mechanism. Due to very strict technical requirements, the accuracy of its on-off angle is relatively high. It is an important indicator of this product. As customers' requirements for the value of the switch stroke point continue to increase, the accuracy standard of the product is also increasing. The traditional test method uses a simple angle indicator and the indicator point on the switch shaft. Observe from the position, make an indicator light to indicate the on-off of the contact, turn the switch by hand, use the indicator light to display the on-off point, and observe the angle to detect, it is completely dependent on manual operation, the efficiency is very low and it cannot provide stable and effective accurate data come out

Embodiment
[0051] In the working process, the grating angle encoder, when the switch fixture is clamped and the probe and the contact piece are in good contact, as long as the drive motor drives the reducer to rotate the switch to be inspected, it will also rotate by a corresponding angle, so that the switch to be inspected will pass through The breakpoint stroke parameters are recorded by the lower computer.
[0052] In order to be able to store the test results and record data through the host computer, display the test data on the screen faithfully, and analyze and judge whether the item is qualified according to the technical requirements, and the necessary data can also be saved.
[0053] Working principle: According to different angle standards of auxiliary switches, set the upper and lower limits of tolerance, adjust the starting point (zero point), the detection is ready, start the detector, the stepping motor runs to make the switch complete a stroke, and the lower computer will ...

A FK auxiliary switch on-off angle detector of the invention includes an upper computer, a lower computer and an actuator. The lower computer includes a liquid crystal display, a digital signal processing motherboard and a motor driving circuit. After the digital signal processing motherboard is connected with the liquid crystal display and the motor driving circuit, the digital signal processingmotherboard, the liquid crystal display and the motor driving circuit are installed in the same shell. The digital signal processing motherboard controls the work of the actuator through the motor driving circuit. The digital signal processing motherboard collects position data detected by a grating angle encoder through a signal line. The digital signal processing motherboard collects opening andclosing contact data of all the on-off points of an auxiliary switch through a signal line. The lower computer computes and processes the position data and the switch contact data, and the data is preliminarily displayed through the liquid crystal display. The data is saved and uploaded to the upper computer, and the upper computer analyzes, displays, records and prints the data. Only microsecondtime is needed for scanning a cycle. The grating angle encoder satisfies the detection of an auxiliary switch in high-precision and batch production.
