Abstract
The invention discloses a method and structure for regulating vibration amplitude of a mechanical vibration device. The mechanical vibration device generates vibration through an eccentric shaft; at least one eccentric sleeve is sheathed on the eccentric shaft of the mechanical vibration device, so that the eccentric sleeve can not generate relative rotation on the eccentric shaft; and the vibration amplitude of the mechanical vibration device is regulated through changing the angle of the eccentric sleeve sheathed on the eccentric shaft. According to the invention, the mounting angle between the eccentric sleeve and the eccentric shaft is regulated, so that the eccentric distance of the vibration gravity center of a vibration source consisting of the eccentric sleeve and the eccentric shaft is changed, thereby obtaining different vibration amplitudes. The method provided by the invention can be used for regulating the vibration amplitude; and the structure provided by the invention is simple, is convenient to use and easy to fabricate, and has low cost. By using the method and the structure, the vibration amplitude of the mechanical vibration device can be conveniently regulated according to production needs.

Summary of the invention
The objective of the invention is to, provide a kind of and not only can regulate amplitude but also the amplitude control method and the structure of mechanical vibrator simple in structure, easy to use, to overcome the deficiencies in the prior art.
Technical scheme of the present invention: the amplitude control method of a kind of mechanical vibrator of the present invention is, comprise by the vibrative mechanical vibrator of eccentric shaft, on the eccentric shaft of mechanical vibrator, overlap an eccentric bushing at least, eccentric bushing can not be produced relative rotation on eccentric shaft, and regulate the amplitude that mechanical vibrator vibrates by the different angles that the change eccentric bushing is enclosed within on the eccentric shaft.
By the mode that key connects or screw is fixing eccentric bushing can not be produced relative rotation on eccentric shaft.
Amplitude adjustment structure according to a kind of mechanical vibrator of method of the present invention design is, comprise the eccentric shaft that is installed on the mechanical vibrator bearing, at least be with an eccentric bushing on eccentric shaft, eccentric bushing connects by key or the screw ways of connecting is fixed on the eccentric shaft.
When connecting by the key ways of connecting, on eccentric shaft, be with an eccentric bushing at least, on the position that is with eccentric bushing of eccentric shaft, be provided with keyway, on eccentric bushing, also be provided with keyway, and eccentric shaft and each eccentric bushing all interconnect by a key that is embedded in the keyway respectively.
On the position that is with eccentric bushing of above-mentioned eccentric shaft, be provided with at least 2 keyways, on eccentric bushing, be provided with 1 keyway, and eccentric shaft and each eccentric bushing all interconnect by a key that is embedded in the keyway respectively.
Perhaps on the position that is with eccentric bushing of aforementioned eccentric shaft, be provided with 1 keyway, on eccentric bushing, be provided with at least 2 keyways, and eccentric shaft and each eccentric bushing all interconnect by a key that is embedded in the keyway respectively.
On above-mentioned eccentric shaft, be provided with eccentric segment, on each eccentric segment, all be provided with the keyway that is connected with eccentric bushing by key.
Owing to adopted technique scheme, the present invention is by the different setting angles of adjustment eccentric bushing with eccentric shaft, make the eccentric distance of the center of vibration of the vibration source that eccentric bushing and eccentric shaft be combined into that different changes, the so just amplitude that can obtain varying in size take place.Therefore, the present invention compared with prior art, the present invention not only has the advantage that can regulate amplitude, but also has advantages such as simple in structure, easy to use, reliable in action, making be easy, with low cost.Use the present invention, can adjust the amplitude of mechanical vibrator easily according to the needs of producing.
