Description
Technical field
The present invention relates to the vibrator that a kind of frequency increase amplitude changes automatically.Can be applied in the plurality of devices such as vibration screening, vibrating compacting, destressing and operating mode.
Background technology
General vibrator, the change of frequency, can't affect the change of amplitude, if when changing frequency, corresponding change amplitude, must design the structure of luffing in addition, and carry out corresponding operating-controlling mechanism.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of structure simple, to increase the vibrator that amplitude changes automatically without the need to the frequency of other operating-controlling mechanism.
The object of the present invention is achieved like this:
A kind of frequency increases the vibrator that amplitude changes automatically, it comprises fixed frame, described fixed frame is laterally equipped with a turning cylinder, described turning cylinder is connected by bearing with fixed frame, turning cylinder in described fixed frame is fixedly installed a rotating mechanism, rotating mechanism comprises a rotating bezel and rotating bezel lid, wherein rotating bezel is fixed on turning cylinder, rotating bezel is away from one end connection of rotating frame lid of turning cylinder, a cavity is formed between rotating bezel and rotating bezel lid, spring and movable block is provided with in cavity, wherein one end of spring is connected with the inwall of rotating bezel lid, the other end of spring is connected with movable block.
Movable block offers the through hole of above-below direction.
Lateral wall and the rotating bezel madial wall of movable block are fitted.
Damping fluid is filled with in cavity.
Under nature, movable block is close to the inwall of rotating bezel near turning cylinder one end due to the elastic force of spring.
The left right lateral fixed frame of described bearing is connected to left end cap and right end cap.
Compared with prior art, the invention has the beneficial effects as follows:
The vibrator that frequency increase amplitude of the present invention changes automatically is along with the increase of input speed, and be also the increase of frequency, the skew of position can occur movable block, thus causes the change of amplitude.The present invention have structure simple, frequency can be realized without the need to other operating-controlling mechanism increase the advantage that amplitude changes automatically.

Detailed description of the invention
See Fig. 1 ~ Fig. 2, a kind of frequency that the present invention relates to increases the vibrator that amplitude changes automatically, and it comprises fixed frame 1, and described fixed frame 1 comprises base 1.1 and fixed cap 1.2, and base 1.1 is connected by the first bolt 1.3 with fixed cap 1.2.Described fixed frame 1 is laterally equipped with a turning cylinder 2, the left end of turning cylinder 2 extend out to fixed frame 1 left, turning cylinder 2 left end is provided with transmission keyway, described turning cylinder 2 is connected by bearing 3 with fixed frame 1, and the left right lateral fixed frame 1 of described bearing 3 is connected with left end cap 1.6 and right end cap 1.7 respectively by the second bolt 1.4 and the 3rd bolt 1.5.On turning cylinder 2 in described fixed frame 1, bias is fixedly installed a rotating mechanism 4, rotating mechanism 4 comprises a rotating bezel 4.1 and rotating bezel lid 4.2, wherein rotating bezel 4.1 is fixed on turning cylinder 2, rotating bezel 4.1 passes through the 4th bolt 4.3 connection of rotating frame lid 4.2 away from one end of turning cylinder 2, a cavity is formed between rotating bezel 4.1 and rotating bezel lid 4.2, spring 4.4 and movable block 4.5 is provided with in cavity, wherein one end of spring 4.4 is connected with the inwall of rotating bezel lid 4.2, the other end of spring 4.4 is connected with movable block 4.5, movable block 4.5 can move in rotating bezel 4.1, movable block 4.5 offers the through hole of above-below direction, lateral wall and rotating bezel 4.1 madial wall of movable block 4.5 are fitted.Damping fluid 5 is filled with in cavity.Under nature, movable block 4.5 is close to the inwall of rotating bezel 4.1 near turning cylinder 2 one end due to the elastic force of spring 4.4.
Operation principle:
When rotational power is passed to after on turning cylinder 2, rotating mechanism 4 starts to rotate, and movable block 4.5 also rotates thereupon together, and along with the increase of rotational speed, movable block 4.5, due to the effect of centrifugal force, can overcome the resistance of spring 4.4, move laterally; And along with movable block 4.5 outwards movement, vibrator can be caused to vibrate the outer of eccentric throw and move; The increase of vibrator amplitude will be caused like this.And (turning cylinder 2 in fixed frame 1 is fixedly installed with one heart a rotating mechanism 4) when rotating bezel 4.1 makes shape as shown in Figure 2, the reduction of vibrator amplitude will be caused.The setting of damping fluid 5, can stablize the location in movable block 4.5 moving process.
