See also Fig. 1, the structural representation of the plane vibration sample pulverizer that Fig. 1 provides for the embodiment of the invention.
Plane vibration sample pulverizer provided by the invention comprises: frame 1, drive unit, eccentric shaft 10, vibrating disk 9 and reducing mechanism.Wherein, drive unit is arranged on the described frame 1, this drive unit can be motor 3, air motor or hydraulic motor etc., eccentric shaft 10 is arranged on the described frame 1 by bearing, so it is rotatable, described drive unit and this eccentric shaft 10 link to each other by transmission device, and this transmission device can be driving-belt (by belt wheel 2 transmissions), gear or driving-chain etc.Vibrating disk 9 links to each other with described eccentric shaft 10, and promptly this eccentric shaft 10 links to each other with vibrating disk 9 by bearing equally, and reducing mechanism is fixed on the described vibrating disk 9 by hold down gag 4.
The present invention is by adopting eccentric shaft 10 supporting vibrating disks 9, link to each other with eccentric shaft 10 by transmission device by drive unit and to realize the power input, make vibrating disk 9 high speed rotary under power drive, reducing mechanism on the vibrating disk 9 is in company with high-speed motion, make reducing mechanism produce exciting force, high-speed impact, roll the granule materials in the reducing mechanism, thereby realize the purpose of powder process.The present invention has following advantage:
1. drive unit separates with vibrating disk 9, and independent stationary is installed, and drive unit no longer participates in vibration, improved the condition of work of drive unit, drive unit mounting flange and case strength need not to strengthen, and have reduced the requirement to drive unit, have improved the service life of drive unit greatly.
2. the drive unit independent stationary is installed, and the transition bindiny mechanism of having simplified drive unit has reduced attaching parts, has saved material, has reduced the production difficulty, is convenient to production, installation and maintenance.
3. drive unit is by actuator drives eccentric shaft 10, the main load of drive unit output shaft has only driving torque, no longer bear radial load, axial force and three kinds of load of moment of torsion when eccentric block is installed, reduced the load of output shaft, drive unit is under the normal duty turns round.
4. drive unit separates with vibrating disk 9, no longer participates in vibration, has reduced the quality of vibrating body, thereby has reduced the energy requirement that produces vibration work, can reduce the power of drive unit, can save energy and reduce the cost.
5. changing the eccentric block exciting is the eccentric shaft exciting, does not need to adopt other measures to reduce drive unit output shaft load, has saved material.
6. be rigidly connected with eccentric shaft between vibrating disk and frame, and connect, do not need to carry out the combo of spring rate during installation, the Problem of Failure of spring rate also can not occur, reduced assembly difficulty, also reduced fault rate without spring.
In order further to optimize technique scheme, eccentric shaft 10 can be for a plurality of, and each eccentric shaft 10 is distributed in the periphery of described vibrating disk 9.Preferred each eccentric shaft 10 to the distance in the center of circle of this vibrating disk 9 equates, also can make each eccentric shaft 10 to the distance in the center of circle of this vibrating disk 9 not wait, if do not wait, then needs the eccentric distance of eccentric shaft 10 is adjusted.The enabling capabilities that a plurality of eccentric shafts 10 can improve vibrating disk 9 is set, motor 3 only with a plurality of described eccentric shafts 10 in one link to each other by transmission device.In the present embodiment, eccentric shaft 10 is preferably three, and is that the center evenly distributes with the center of circle of described vibrating disk 9.
Reducing mechanism provided by the invention can specifically comprise: pulverize alms bowl 8, pulverize ring 7, pulverize rod 6 and gland 5.Wherein, pulverize alms bowl 8 and be arranged on the described vibrating disk 9, pulverize ring 7 and be placed in the described pulverizing alms bowl 8, pulverize rod 6 and be placed in the described pulverizing ring 7, gland 5 be located on described pulverizing alms bowl 8 open top end, and described hold down gag 4 is pressed on the described gland 5.When vibrating disk 9 rotates, pulverize the pulverizing ring 7 in the alms bowl 8 and pulverize rod 6 and clash into, roll pulverizing with being placed on its inner material.
As shown in Figure 2, the structural representation of the hold down gag that provides for the embodiment of the invention of Fig. 2.
The course of work of this hold down gag is specially: pull operating grip 41 clockwise, make action bars 44 also clockwise rotate, because fairlead 47, sliding axle 46, big connecting rod 42 and action bars 44 are connected to form quadric chain by bearing pin, make between fairlead 47 and the big connecting rod 42, can only rotate mutually between big connecting rod 42 and the action bars 44 and between action bars 44 and the sliding axle 46, because the interlock between each parts of linkage, thereby driving big connecting rod 42 is that the center clockwise rotates with the bearing pin of d end also, under the restriction of the through hole of fairlead 47, sliding axle 46 can only move downward along through hole, and then the platen 48 that drives sliding axle 46 lower ends compresses reducing mechanism, promptly finished the work that compresses to reducing mechanism.Otherwise, when needs stop to compress work, only need pull operating grip 41 counterclockwise, can drive sliding axle 46 moves upward along the through hole of fairlead 47, it is up and then reducing mechanism is loosened to drive platen 48 simultaneously, and concrete operational detail is opposite when compressing, and uses for reference mutually to get final product.
The bar linkage structure of this hold down gag has changed stress form, has reduced stress surface, thereby has reduced frictional force, has reduced wear extent, has prolonged the service life of hold down gag; During work, finish, make operation fast, improved operating efficiency greatly, in addition,, prolonged the arm of force of action bars, make operation more laborsaving owing to be connected with operating grip on the action bars because the interlock between each parts of linkage is instantaneous basically.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
