Abstract

The invention is a mechanical device for coaxially driving multi-layer discs to rotate simultaneously or separately. It utilizes segmental shifting of the drive shaft in the same radius, same width, and different arc length guide grooves on the multi-layer roulette to control the simultaneous or separate rotation of the multi-layer roulette to realize the insertion or withdrawal of the multi-layer filter. It has special value for using one motor to realize rotation control of multi-layer roulette in limited space.

Description

A multi-layer roulette rotating device

technical field

The invention belongs to a mechanical device for coaxially driving multi-layer discs to rotate simultaneously or separately.

Background technique

In optical equipment, one or several layers of filters need to be combined in the optical path for spectral analysis. In medical radiation equipment, according to the characteristics of the rays, filters are combined in the radiation field to optimize the characteristics of the rays. Usually the method of artificially adding filter discs is inefficient and unsafe.

The invention adopts the method that the multi-layer discs are rotated simultaneously or separately under the coaxial drive to drive the filters of each layer to be inserted or withdrawn in any combination, which overcomes the shortcomings of manual operation of the filters, and provides a mechanical device for the automation of filter operations. solution.

Contents of the invention

The invention provides a mechanical device for coaxially driving multi-layered discs to rotate simultaneously or separately, aiming at realizing the automation of the operation of the filter disc.

Fig. 1 is a structure diagram of a multi-layer wheel disc involved in the present invention. It consists of roulette 1, roulette 2, and roulette 3, which correspond to guide grooves 9, 10, and 11 respectively, and the arc length of the guide grooves presents an arithmetically increasing shape with the same radius and the same groove width.

Fig. 2 is a coaxial stacked installation structure diagram of multi-layer roulettes. It consists of coaxially superimposed wheel discs 1, 2 and 3, a toggle shaft 4, a tension spring 5 hanging on each wheel disc, and bayonet pins 9. When the left ends of the guide grooves 9, 10, and 11 are aligned, the right ends of the wheel discs 1, 2, and 3 present a shape that is lengthened successively on the same radius. The device can have more than three layers of roulette, and the number of roulette layers can be increased by dividing the arc length equidistantly in the circumference. Drive 4 with a motor to realize the simultaneous or separate rotation of the multi-layer discs (the dotted line in the figure indicates the different positions reached by 4), and drive the filters of each layer to insert or withdraw respectively.

The beneficial effect of the present invention is that a motor solves the mechanical device for inserting multi-layer filters in a limited space, reduces the volume of the equipment, and is of great value in solving the problem of frequent replacement and insertion of filters in the fields of optics and medical X-rays.

Detailed ways

As shown in Figure 2, the multi-layer roulette coaxial superimposed installation structure diagram, the working process of the multi-layer roulette is as follows:

1) When the three layers of roulettes are required to drive the filters to be inserted, 4 rotates counterclockwise under the drive of the motor, and drives roulettes 1, 2, and 3 to rotate counterclockwise at the same time until they are stuck at 9 places;

2) When two layers of roulettes are required to drive the filter to be inserted, first 4 is driven counterclockwise by the motor, and the roulettes 1, 2, and 3 are driven counterclockwise to 9 and stuck at the same time, and then 4 is rotated clockwise to 1 to 6 position, toggle 1 to disengage from 9, and turn clockwise under the pulling force of 5;

3) When a layer of roulette is required to drive the filter to be inserted, first 4 is driven counterclockwise by the motor, and the roulette 1, 2, and 3 are driven counterclockwise to 9 and stuck at the same time, and then 4 is rotated clockwise to 1 to 6 Position, toggle 1 to disengage from 9, turn clockwise under the pulling force of 5; 4 continue to turn clockwise to the 7 position of 2, toggle 2 to disengage from 9, and turn clockwise under the pulling force of 5;

4) When there is no need to insert the filter, 4 continues to turn clockwise to the 8 position of 3, toggle 3 to disengage from 9, and turn clockwise under the pulling force of 5;

5) By analogy, the method of inserting and withdrawing the filter is the same as above for multi-layer roulettes with more than three layers.
