Specific embodiment
Describe the preferred embodiments of the present invention below in conjunction with the accompanying drawings in detail.
Embodiment
Diaphragm type hydraulic exciting single barrel vibrating mill, by cylinder 1, back-moving spring group 2, diaphragm type hydraulic vibration exciter 3, vibration damping bullet
Spring group 4, base 5 and hydraulic means are constituted, and instead of general mechanical type vibrator, liquid using diaphragm type hydraulic vibration exciter 3
Pressure device includes switch valve 6, motor 7, liquid storage pool 8, liquid pump 9, conduit under fluid pressure 10, as shown in Figure 1.
From accompanying drawing 5, cylinder 1 is formed by mill tube 1-1, side plate 1-2, base plate 1-3 consolidation;Diaphragm type hydraulic vibration exciter 3
It is formed by connecting by exciting plate one 3-1, exciting plate two 3-3 and thin film 3-2, that is, exciting plate one 3-1, exciting plate two 3-3 are two phases
Mutually parallel exciting plate, thin film 3-2 is made with soft exciting plate material that is non-leakage, being difficult to extend, and switch valve 6 is by motor 7
Drive, liquid pump 9 can be that self-contained motor 7 drives, the upper plane Joint of the base plate 1-3 of cylinder 1 and exciting plate, thin film 3-2
A ', B ' face seal opposite with two exciting plates is connected, and can be being tightly connected of bonding, and such as Fig. 2 or bolt presses are solid
Fixed is tightly connected, such as Fig. 3, can also be only contact and unfixed is tightly connected.
A ', B ' face all can be divided into three regions, such as Fig. 2:All the time the region a contacting with thin film 3-2;Begin with thin film 3-2
Discontiguous region b eventually, other region c, region a are not connected with region b, and thin film 3-2 is only connected with flat board in region a, thin film
3-2 and two exciting plates constitute a space closed, and discontiguous part can be with free bend with two exciting plates, and exciting plate sets
Put passage 3-4, thus the volume of this closing space is variable, this closing space passes through conduit under fluid pressure 10 and liquid pump 9
It is connected with switch valve 6, switch valve 6 other end connects liquid storage pool 8, pump is continually provided liquid, and switch valve 6 periodically will be closed
The liquid in space enters liquid storage pool 8.
Back-moving spring group 2 should >=1 group, every group by least 2 back-moving springs 2-3,2-5, each 1 reset pressing plate 2-2 in two ends,
The each 2 nut 2-1 in two ends, a threaded rod 2-4 are constituted, and 2 back-moving springs 2-3,2-5 are respectively arranged in by threaded rod 2-4
Outside two exciting plates, back-moving spring 2-3,2-5 two ends are contacted with exciting plate, reset pressing plate 2-2 respectively, and threaded rod 2-4 is certainly
Corresponding hole on back-moving spring 2-3,2-5, reset pressing plate 2-2 and exciting plate is passed through by ground, nut 2-1 is arranged on threaded rod 2-4
Concrete mutually above the vibration damping pressing plate 5-1 of the outer end of upper reset pressing plate 2-2, the bottom of threaded rod 2-4 and shock-absorbing spring group 5, leads to
Overregulating pretension makes back-moving spring 2-3,2-5 be in pressured state all the time.
The effect of back-moving spring group 2 be when in thin film, liquid increases or decreases so that diaphragm type hydraulic vibration exciter 3 two
Distance suitably increases or resets in time exciting plate up and down, and that is, in thin film, liquid returns to the position before liquid increases, guarantee grinding machine
It is in normal vibration working condition.
Shock-absorbing spring group 4 answers >=1 group, and every group by least one shock-absorbing spring 4-2,1 vibration damping pressing plate 4-1,2 leads
4-3, a lower seat 4-4 composition, concrete mutually above threaded rod 2-4 one end and vibration damping pressing plate 4-1, vibration damping pressing plate 4-1 lower plane and
Lead 4-3 is consolidated with plane on lower seat 4-4, shock-absorbing spring 4-2 is installed on vibration damping pressing plate 4-1 by lead 4-3 respectively
And lower seat 4-4 between, lower seat 4-4 and base 5 concrete mutually, base 5 is fixed on ground.The effect of shock-absorbing spring group 4 is can
The transmission to ground for the vibration of minimizing system, and reduce consequent noise.
In embodiment, the frequency of reasonable design, the rigidity of adjustment back-moving spring 2-3,2-5 or adjustment switch valve 6 can make
System works under Near resonance oscillating state, thus reaching the big driving of small-power, the purpose reducing energy consumption, significantly improving efficiency.
Because thin film 3-2 is to be made with the material being difficult to extend, so when liquid injection closing space, thin film 3-2
The pressure of internal liquid can change, and overcomes the active force of back-moving spring 2-3,2-5 and other resistance to make the distance of two exciting plates
Increase;When valve is in opening state, under back-moving spring 2-3,2-5 effect, the liquid that liquid thin film 3-2 within and pump export
All liquid storage pool 8 will be entered through valve, and so that liquid pressure is declined, so that the distance of two exciting plates is reduced, thus completing vibration cycles.
What the present invention was different from Normal hydraulic and pneumatic means is:Without piston, thus do not exist sealing because piston causes, leakage,
Friction and wear.
Due to not leaking, it is possible to use water is as medium.Closing space has very big work area, even if so internal
The little but total vibration force of pressure can be very big, and the Another reason that diaphragm type vibrator can be put to apply is and General Oscillation
Mill requires the less situation of amplitude to match.The section that diaphragm type does not contact the edge of plate face is a semi arch, and it is maximum
Radius R is slightly larger than exciting amplitude.
The stress of thin-film material is directly proportional to internal pressure and arc radius, as long as therefore arc radius are sufficiently small, current material is just
The intensity requirement to thin film 3-2 for the pressure can be met.The rotating speed changing switch valve 6 can change frequency of vibration, changes the stream of pump
Amount can change amplitude.Therefore the present invention infinitely can not shut down Frequency And Amplitude Modulation, and Frequency And Amplitude Modulation is unrelated.
Due to the vibration force of diaphragm type vibrator and cylinder 1 contact position be equally distributed so that system stress relatively
Good;The relative motion of thin film 3-2 and two exciting planes is to roll and non-slip, so no friction and wear.Using thin material
Manufacture diaphragm type, flexural fatigue can be reduced and damage.Due to threaded rod 2-4 vibration displacement and upper and lower plastid of poor quality become just
Ratio, therefore configuration quality exactly, along with shock-absorbing spring 4-2 effect so that it may so that machine to the vibration interference on ground almost
Equal to zero.
