Quartz crystal oscillator fully automatic frequency modulator convenient for detection and maintenance

Abstract

The invention relates to the technical field of quartz crystal oscillators, and discloses a quartz crystal oscillator fully automatic frequency modulation machine convenient for detection and maintenance, include a lower shell, the top part of the lower shell is fixedly connected with a card plate, the top of the lower shell is movably connected with the upper shell, the bottom of the upper shellis provided with a finite position groove, the card plate is located in the inside of the limiting groove, the inner top wall of the limiting groove is fixedly connected with a soft cushion, a throughhole is formed in the lower case, the inside of the through hole is movably connected with a rotating rod, the left and right ends of the rotating lever extend to the outside of the lower shell, thetop of the rotating lever and the left and right sides of the lower shell are fixedly connected with connecting plates, the opposite sides of the two connecting plates are fixedly connected with sliding bars, and the left and right sides of the lower shell and the corresponding two sliding bars are provided with annular grooves. The quartz crystal oscillator fully automatic frequency modulator convenient for detection and maintenance is convenient for detection and maintenance, saves time and labor, and improves work efficiency.

Description

technical field [0001] The invention relates to the technical field of quartz crystal oscillators, in particular to a fully automatic frequency modulation machine for quartz crystal oscillators which is convenient for detection and maintenance. Background technique [0002] Quartz crystal oscillator is a quartz crystal resonator made of quartz material, commonly known as crystal oscillator, which plays the role of generating frequency, has stability and good anti-interference performance, and is widely used in various electronic products. Quartz crystals are natural and artificial. , is an important piezoelectric crystal material, the quartz crystal itself is not an oscillator, it can only generate oscillation with the help of active excitation and passive reactance network. [0003] In the process of testing and production of quartz crystal oscillators, it is necessary to use the quartz crystal oscillator automatic frequency modulation machine to adjust the frequency of the...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a quartz crystal oscillator automatic frequency modulation machine that is convenient for detection and maintenance, which has the advantages of convenient detection and maintenance, time saving and labor saving, and improved work efficiency, and solves the problem of disassembling the shell of general equipment for detection and maintenance. At the same time, because multiple screws are installed at the four corners, it is extremely troublesome to disassemble and detect, time-consuming and labor-intensive, and affects work efficiency.
