Specific embodiment
Describe the preferred embodiments of the present invention below in conjunction with the accompanying drawings in detail.
Embodiment
Diaphragm type hydraulic exciting Near resonance oscillating type single barrel vibrating mill, by cylinder 1, Near resonance oscillating groups of springs 2, diaphragm type hydraulic exciting Device 3, shock-absorbing spring group 4, base 5 and hydraulic means are constituted, and be instead of using diaphragm type hydraulic vibration exciter 3 general mechanical Vibrator, hydraulic means include 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 consolidations;Diaphragm type hydraulic vibration exciter 3 It is formed by connecting by one 3-1 of exciting plate, exciting plate two 3-3 and film 3-2, i.e. one 3-1 of exciting plate, two 3-3 of exciting plate are two phases Mutual parallel stiffener plate, film 3-2 are made with soft exciting plate material that is non-leakage, being difficult to extend, and switch valve 6 is by motor 7 drive, and liquid pump 9 can be that self-contained motor 7 drives, the base plate 1-3 of cylinder 1 and the upper plane Joint of exciting plate, film 3-2 A ', B ' face opposite with two exciting plates is tightly connected, and can be being tightly connected for 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 can be divided into three regions, such as Fig. 2:All the time the region a contacted with film 3-2;Begin with film 3-2 Whole discontiguous region b, other regions c, region a are not connected with region b, and film 3-2 is only connected with flat board in region a, film 3-2 and two exciting plates constitute the space of a closing, can be set with free bend, exciting plate with the discontiguous part of two exciting plates Passage 3-4 is put, so as to the volume of this closing space is variable, this closing space is by conduit under fluid pressure 10 and liquid pump 9 It is connected with switch valve 6,6 other end of switch valve connection liquid storage pool 8, pump are continually provided liquid, switch valve 6 periodically will closing The liquid in space enters liquid storage pool 8.
Near resonance oscillating groups of springs 2 answers >=1 group, per group by least one main vibration spring 2-4,2 back-moving springs 2-3,2-6, and two ends Each 1 reset pressing plate 2-2, each 2 nut 2-1 in two ends, a threaded rod 2-5 composition, such as Fig. 4, main vibration spring 2-4 pass through screw thread Bar is installed on the inside of two exciting plates, and 2 back-moving springs 2-3,2-6 are respectively arranged on the outside of two exciting plates by threaded rod, Back-moving spring 2-3,2-6 one end is fixed on flat board, and reset pressing plate 2-2 is fixed on the other end of back-moving spring 2-3,2-6, screw thread Bar passes freely through corresponding hole on back-moving spring 2-3,2-6, reset pressing plate 2-2 and exciting plate, and nut 2-1 is arranged on threaded rod The other end of upper reset pressing plate 2-2, makes back-moving spring 2-3,2-6 be in pressured state by adjusting pretension.
The effect of Near resonance oscillating groups of springs 2 is the two exciting plates of diaphragm type hydraulic exciting body when liquid increases in film 3-2 Up and down distance is amplitude increase, while the exciting force of Near resonance oscillating groups of springs 2 is acted on two exciting plates, plays and increases exciting, fast Speed and the further effect of increase amplitude, make grinding machine be in Near resonance oscillating state.
Shock-absorbing spring group 4 answers >=1 group, per group by least one shock-absorbing spring 4-2,1 vibration damping pressing plate 4-1,2 lead columns Seat 4-4 compositions under 4-3, a shock-absorbing spring, concrete mutually above threaded rod one end and vibration damping pressing plate 4-1 are put down under vibration damping pressing plate 4-1 It is consolidated with lead column 4-3 under face and shock-absorbing spring on seat 4-4 in plane respectively, shock-absorbing spring 4-2 is installed on by lead column 4-3 Under vibration damping pressing plate 4-1 and shock-absorbing spring between seat 4-4, seat 4-4 and 5 concrete mutually of base under shock-absorbing spring, base 5 are fixed on ground On.The effect of shock-absorbing spring group 4 is transmission of the vibration to ground that can reduce system, and reduces resulting noise.
Reasonable design, the rigidity of adjustment main vibration spring 2-4 and back-moving spring 2-3,2-6 or adjustment switch valve in embodiment 6 frequency can make system work under Near resonance oscillating state, so as to reaching the big driving of small-power, reducing energy consumption, significantly improve effect The purpose of rate.
As film 3-2 is to use to be difficult made by the material for extending, so when liquid injects closing space, film 3-2 The pressure of internal liquid can change, and overcome the active force and other resistances of back-moving spring 2-3,2-6 to make the distance of two exciting plates Increase;When valve is in opening state, under back-moving spring 2-3,2-6 effect, the liquid of the liquid and pump output inside film 3-2 Jing valves are entered into liquid storage pool 8 all, is declined liquid pressure, is reduced the distance of two exciting plates, so as to complete a vibration cycles. What the present invention was different from Normal hydraulic and pneumatic means is:Without the need for piston, thus do not exist sealing because piston causes, leakage, Friction and wear.
Due to without leakage, it is possible to use water is used 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 that the less situation of amplitude matches.It is a semi arch that diaphragm type does not contact the section of the edge of plate face, and which 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 Intensity requirement of the pressure to film 3-2 can be met.The rotating speed for changing switch valve 6 can change vibration frequency, change 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.
As diaphragm type vibrator is equally distributed with the vibration force of 1 contact position of cylinder so that system stress compared with It is good;The relative motion of film 3-2 and two exciting planes is to roll and non-slip, so without friction and wear.Using thin material Manufacture diaphragm type, can reduce flexural fatigue damage.As the vibration displacement of threaded rod is directly proportional to the of poor quality of upper and lower plastid, Therefore configuration quality exactly, along with the effect of shock-absorbing spring 4-2, so that it may so that machine is no better than to the vibration interference on ground Zero.
