Description
Technical field
The present invention relates to a kind of pneumatic vibrator.
Background technology
According to vibrator institute power consumption form and operation principle, mainly contain electric vibrator (rotation, straight line, magnetic), the vibrator that surges, pneumatic vibrator (rotation, straight line) in the present vibrating machine industry.Electric vibrator is one group of eccentric block with motor drives two shaft extension ends, produces vibration force, and invariablenes turning speed is non-adjustable, and the vibration force adjustment is inconvenient, for high frequency, high temperature and explosion-proof required particular design.Surge exciter structure complicacy, heaviness, Installation and Debugging are extremely inconvenient.Pneumatic vibrator of the same type mainly contains seat, covers, is with formations such as unbalanced rotor, bearing; Rolling bearing is pressed in the bearing chamber; Bearing bore diameter is connected with being with unbalanced two ends of rotor cylinder; Limit the radial diameter of rolling bearing, reduced the physical life of rolling bearing, can receive great dynamic load at the running middle (center) bearing simultaneously.
Summary of the invention
The technical problem that the present invention will solve and the technical assignment of proposition are that the prior art scheme is improved and improved, and a kind of impact type pneumatic vibrator are provided, to reach good He the stable purpose of antivibration ability.For this reason, the present invention takes following technical scheme.
A kind of impact type pneumatic vibrator; Comprise the device seat of establishing the cylindrical piston chamber, the inlet suction port that is communicated with plunger shaft and silencer; It is characterized in that: described plunger shaft vertically is provided with, and is provided with the cylindrical piston that can move up and down in the plunger shaft, second air flue that internal piston has the first axial air flue and intersects vertically with first air flue; The first air flue open upper end, its lower end intersect with second air flue and are communicated with; The bottom of plunger shaft is the discharge chamber that is communicated with silencer, and inlet suction port is positioned at the top of discharge chamber, moves up and down at piston that second air flue can be connected with inlet suction port, discharge chamber in the process; The piston periphery of second air flue top is established annular air and is pushed away face, and gas pushes away distance at the bottom of face to the piston distance at the bottom of greater than inlet suction port air admission hole lower wall to plunger shaft.In original state, piston relies on gravity to be positioned at the bottom of device seat, and the plunger shaft of piston top communicates with the external world through first air flue and second air flue, and air pressure equals an atmospheric pressure.When piston received the powerful air pressure of air pump access, annular air pushed away face and receives the force urges piston stroking upward, and second air flue and discharge chamber are isolated; The piston fast uplink; When piston rose to a certain degree, second air flue was communicated with inlet suction port, and gases at high pressure get in the plunger shaft of piston top through second air flue and first air flue; Piston upper end pressurized, piston begin descending plunger shaft until the piston top and link to each other with ambient atmosphere.Move back and forth the equipment that impacts with this and produce vibration force.This programme piston moves up and down in plunger shaft and realizes vibration, antivibration ability and stable good, and the adjusting of pressing through air inlet can change the speed of piston up-downgoing, changes vibration force, and is easy to adjust, flexible.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature.
Described piston comprises superposed enlarged diameter section and is positioned at the reduced diameter section of enlarged diameter section below; The enlarged diameter section of piston and reduced diameter section intersection form annular air and push away face; Said plunger shaft comprises the chamber, large aperture that matches with the piston enlarged diameter section and is positioned at the chamber, small-bore that chamber, large aperture below and piston reduced diameter section match that described device seat top is provided with the stifle in closed piston chamber.Piston can be inserted in the plunger shaft from top to bottom.
The plunger shaft wall that links to each other with inlet suction port is offered the annular air inlet duct of indent, and air inlet duct connects macroporous cavity and chamber, small-bore.The annular air inlet duct makes piston circumferentially evenly stressed.
Piston gas push away distance at the bottom of face to the piston greater than air inlet duct at the bottom of distance at the bottom of the plunger shaft.
The aperture of described discharge chamber is greater than the chamber, small-bore, and discharge chamber pushes up distance at the bottom of the plunger shaft distance at the bottom of greater than second air flue lower wall to the piston.
Described silencer, inlet suction port are divided into the both sides of device seat, and the air admission hole of silencer and the venthole of inlet suction port are perpendicular to plunger shaft.
Beneficial effect: piston moves up and down in plunger shaft and realizes vibration, antivibration ability and stable good, and the adjusting of pressing through air inlet can change the speed of piston up-downgoing, changes vibration force, and is easy to adjust, flexible.
