Abstract

The utility model discloses a new shutter for the crystal frequency fine turning device, which is composed of a shutter blade (6), a thrusting rod (3) and an electromagnet (1) in which a magnet core (2) is arranged and is characterized in that: the electromagnet (1) is a thrusting electromagnet and a distance is kept between the top part of magnet core (2) and the thrusting rod (3) that is connected with the shutter blade (6) through a rotating shaft (4) on which a dynamic spring (5) is arranged. The utility model is an ideal new shutter for the crystal frequency fine turning device, which can improve the working efficiency through increasing the closing and opening speed of the shutter, increase the fine turning precision, and reduce energy consumption and cost and personnel quality.

Description

The novel shutter of crystal frequency freqency fine adjustment machine

(1) technical field:

The utility model relates to freqency fine adjustment machine shutter technical field, is the novel shutter of a kind of crystal frequency freqency fine adjustment machine specifically.

(2) background technology:

Existing frequency trimmer shutter is to utilize the tractive magnet energising, and Magnetic force tracting is closed shutter, and the power-off restoration spring is upspring and opened shutter, during the energising adhesive, shutter close is because the magnet reaction velocity, with the reacting force of back-moving spring, shutter close speed is slower; Outage, the back-moving spring shutter of upspringing is opened because unshakable in one's determination, connecting rod weight is heavier, the shutter opening speed is slower, thereby its production efficiency is low, precision is also influenced, produce consume and labour cost higher, quality of workers is required high, the production cost height.

(3) summary of the invention:

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of novel shutter of crystal frequency freqency fine adjustment machine that improves the freqency fine adjustment machine shutter speed, improves trimming precision is provided, mainly be to increase work efficiency, improve trimming precision, reduction consumption, reduction expense, reduce peopleware by raising shutter close, opening speed.

In order to achieve the above object, the utility model is achieved in that the novel shutter of crystal frequency freqency fine adjustment machine, it comprises blade 6, distance rod 3, electromagnet 1, establish unshakable in one's determination 2 in the electromagnet 1, its special character is that described electromagnet 1 is the thrust electromagnet, between unshakable in one's determination 2 top and the distance rod 3 distance is arranged, distance rod 3 is connected by rotation axis 4 with blade 6, establishes power spring 5 on rotation axis 4.

In order further to realize above-mentioned purpose, the novel shutter of crystal frequency freqency fine adjustment machine of the present utility model, its described power spring 5 also can be tension spring for torsion spring.

The major function of the novel shutter of crystal frequency freqency fine adjustment machine of the present utility model is the fine setting frequency accuracy control to quartz crystal electronic component frequency, the quartz crystal electronic component is a kind of high precision, high stability, low aging frequency is selected and the control components and parts, be widely used in communication, fields such as household electrical appliances, radio and television, robotization control, frequency trim is that quartz crystal electronic component frequency is finely tuned, make it reach the method for certain frequency accuracy, the precision of element frequency is subjected to the control of frequency trimmer and influences.

Compared with the prior art the novel shutter of crystal frequency freqency fine adjustment machine described in the utility model has following good effect: owing to use the thrust electromagnet, between top unshakable in one's determination and distance rod certain distance is arranged, make full use of the thrust electromagnet core after releasing a segment distance, just can have characteristics high-speed, high thrust, improve the shutter opening speed, utilize power spring to close shutter, effectively improved the shutter speed of freqency fine adjustment machine, thereby improved work efficiency, improved the precision of freqency fine adjustment machine, and then reduced consumption and expense, also reduced operative employee's quality simultaneously.

(4) description of drawings:

Fig. 1---structural representation of the present utility model.

(5) embodiment:

In order to understand better and to implement, provide embodiment below in conjunction with accompanying drawing and describe the novel shutter of the utility model crystal frequency freqency fine adjustment machine in detail.

Embodiment 1, referring to Fig. 1, elder generation's good blade 6 of fabrication and processing and distance rod 3, the two is connected with rotation axis 4, mounting torque spring 5 on rotation axis 4 is installed electromagnet 1 below distance rod 3, electromagnet 1 is the thrust electromagnet, fixed installation iron core 2 on electromagnet 1 has distance between 2 distance rods 3 unshakable in one's determination.

Embodiment 2, and tension spring 5 is installed on rotation axis 4, and other is with embodiment 1.

The novel shutter of crystal frequency freqency fine adjustment machine described in the utility model, during energising, the thrust electromagnet promotes unshakable in one's determination, between top unshakable in one's determination and distance rod certain distance is arranged, when thrust and speed reach certain numerical value, the distance rod that promotes unshakable in one's determination, make blade Unscrew shutter, compress torsion spring simultaneously; During outage, the thrust electromagnet core loses power, and the torsional forces of torsion spring makes blade rotary closing shutter.

If the use tension spring is identical with the torsion spring principle.

Claims

1, the novel shutter of crystal frequency freqency fine adjustment machine, it comprises blade (6), distance rod (3), electromagnet (1), establish iron core (2) in the electromagnet (1), it is characterized in that described electromagnet (1) is the thrust electromagnet, between the top of (2) unshakable in one's determination and the distance rod (3) distance is arranged, distance rod (3) is connected by rotation axis (4) with blade (6), establishes power spring (5) on rotation axis (4).
