Torquer pairing method for quartz flexibility accelerometer production

Abstract

The invention discloses a torquer pairing method for quartz flexibility accelerometer production. The torque pairing method comprises the following steps: 1, numbering upper and lower torquers of a whole batch, and testing heights, parallelism degrees and sizes of the torquers and magnetic saturation values of corresponding points; 2, inputting tested data into a computer; 3, calculating and recording a difference value between the magnetic saturation values of the correspondingly numbered upper and lower torquers, and taking out disqualified torquers; 4, simulating pairing of the upper and lower torquers of the whole batch; 5, combining the successfully paired upper and lower torquers into pairs; 6, demagnetizing the successfully paired upper and lower torquers; 7, testing the magnetic induction intensity of four points of the demagnetized upper and lower torquers, re-inputting results into the computer, recording and calculating a difference value of the magnetic induction intensity, and judging whether the upper and lower torquers are qualified or not; 8, integrating all data, forming a report, and printing and filing the report. The pairing method is simple and convenient for inputting operation, is high in pairing success rate, pairing efficiency and quality and can relieve the working intensity.

Description

technical field [0001] The invention relates to a production process, in particular to a matching method for producing upper and lower torque devices in quartz flexible accelerometers. Background technique [0002] In the production of accelerometers, each accelerometer is equipped with two upper and lower magnets pre-filled with a certain magnetic induction intensity—the upper torque device and the lower torque device. The pairing of the upper torque device and the lower torque device is to buckle the upper torque device on the lower torque device. On the top, after being buckled together, the 4 corresponding points correspond to each other. The 4 corresponding points refer to the 4 points on the circumference of the end face of the upper torque device and the lower torque device that are separated by 90°, and the 4 points on the circumference of the end face of the upper torque device. For upper A, upper B, upper C and upper D (as attached figure 1 ), the four points on t...

Problems solved by technology

[0012] 1. In the production process, the pairing of the upper / lower torque devices is all based on experience, and then the calculator is used to calculate manually. Due to the large amount of matching data, not only the workload is large, the matching process is time-consuming, but also the accuracy is poor and errors are prone to occur. ;

[0013] 2. In actual production, it is difficult to find the pairing with the smallest difference in magnetic induction intensity, and it is often impossible to completely match all the upper / lower torque devices, and the success rate of pairing is low
