Abstract
The utility model relates to a shock-absorbing structure based on a quality-tuning damper and belongs to the technical field of shock-absorbing of the damper. The shock-absorbing structure based on the quality-tuning damper comprises a grinding operating platform. An inner hole is formed in a stand column of the grinding operating platform. The inner hole is provided with a supporting rod, a damping vibrator, a long nut, a plastic sleeve, a spacer and the like. The long nut can be regulated to penetrate through and abut against the spacer. The spacer is contacted with the rubber ring and squeezes the rubber ring. Due to the fact that the spacer can be moved through rotation of the nut, the shock-absorbing structure of the quality-tuning damper is capable of regulating and controlling the amount of compression of the rubber ring, the contact force between the spacer and a damper system can be regulated. The shock-absorbing structure based on the quality-tuning damper has important application value on promoting restraining of shock during the ceramic-grinding process and guaranteeing process quality of ceramics-grinding and has the advantages of being simple and compact in structure and easy to control.
Description
Technical field
The utility model relates to a kind of tuned mass damper, is applied to the ceramic grinding worktable, belongs to the damper vibration damping technical field.
Background technique
Along with the high speed development of society, every profession and trade proposes higher requirement to machining.One of most critical factor that affects the machining performance is exactly flutter; The inhibition technology of flutter is to guarantee the workpiece quality of processing, improves the prerequisite of machining efficient, and therefore seeming is even more important, and engineering ceramics processing is no exception.Engineering ceramic material is increasingly extensive in the application in Aero-Space, electronic apparatus, automobile and the field of manufacturing, and the hard fragility of engineering ceramics, high compressive strength, good wear resistance are so that it becomes typical material of difficult machining.The dynamic grinding force of pottery processing is large, grinding force ratio is large, grinding surface quality is wayward, and system easily plays pendulum, and flutter very easily occurs course of working.Flutter causes ceramic finished surface crackle or damage, and machining accuracy is not enough, and tool wear is serious, and the noise of generation also damages operator's physical and mental health.
For the control of flutter in the cutting, researcher both domestic and external has carried out a large amount of research.Generally speaking, can be divided into two large classes: the controlling method of vibration control method and adjustment cutting parameter.In the vibration control method, the difference according to control actuating device character is divided into Active Control Method, passive control methods and half Active Control Method again.
Passive Control type method: but mainly be to reach the effect that vibration damping shakes by in system, adding the absorbing parts.Passive Passive Control does not need additional source of energy, and the principal oscillation system is depended in the work of vibration damper fully, its simple in structure, reliable operation.
The method of Passive Control is a lot, and tuned mass damper (TMD) just belongs to wherein a kind of; Tuned mass damper (TMD) mainly is comprised of spring, damper and mass block, and its working principle is to utilize the inertial force of mass block or the purpose that active controlling force reaches resonance energy-absorbing, minimizing structural response.The tuning quality bump leveller is a technology commonly used in the mechanical vibration field.
The utility model is used for the engineering ceramics manufacture field, compares with the similar damper of the utility model, and features simple structure, easy to adjust, reliable performance is stable.
The model utility content
The purpose of this utility model is to overcome above-mentioned cutting-vibration and suppresses system's deficiency, and a kind of vibration damping structure based on tuned mass damper for suppressing the engineering ceramics flutter is provided.
The technical solution of the utility model is as follows:
A kind of vibration damping structure based on tuned mass damper, comprise a grinding worktable 1, be connected with a grinding worktable column 5 on the grinding worktable 1, grinding worktable column 5 has a through hole, is provided with a strut 2, damped oscillator 4, rubber ring 3, pad 6, adjusting nut 7, sleeve 8 in the through hole; Strut 2 one ends are threaded with worktable 1, the other end cover upper bush 8 and grinding table base 9 Spielpassung.In the damped oscillator 4 two ends grooves rubber ring 3 is housed respectively, damped oscillator 4 is enclosed within on the strut 2, and there is the gap in 2 of struts, rubber ring 3 and strut 2 Surface Contacts.In the damped oscillator rear end one pad 6 being housed contacts with rubber ring.The screw-thread fit at adjusting nut 7 and strut 2 rear portions, rotation adjusting nut 7, the front end of adjusting nut 7 promote pad 6 extruding rubber rings 3.
Adjusting nut 7 is long nut, and rubber ring 3 is selected silica gel or other elastic materials.
Described sleeve 8 is plastic sleeve.
By rotating nut, promote pad extruding rubber ring, thus the decrement that can regulate the control rubber ring, and then the contact force of adjustment rubber ring and damper system.
The beneficial effect that the utlity model has is:
The utility model changes the axial dynamic characteristic of grinding worktable by being adjusted in the adjusting nut on the strut, changes the frictional force size of frcition damper and worktable.Worktable is cut in grinding be in optimum state in the state, when flutter occured, damper system was as the absorbing parts, thereby establishment engineering ceramics Process Chatter occurs.

Embodiment
At first as depicted in figs. 1 and 2, vibration damping structure based on tuned mass damper of the present utility model, comprise a grinding worktable 1, worktable column 5 has a through hole, is provided with a strut 2, damped oscillator 4, rubber ring 3, pad 6, adjusting nut 7, sleeve 8 in the through hole; Strut 3 one ends are threaded with worktable 1, the other end cover upper bush 8 and table base 9 Spielpassung.In the damped oscillator 4 two ends grooves two rubber rings 3 are housed, damped oscillator is enclosed within on the strut 2, has the gap with it, rubber ring 3 and strut 2 Surface Contacts.In the damped oscillator rear end one pad 6 being housed contacts with rubber ring.The screw-thread fit at adjusting nut 7 and strut 2 rear portions, rotation adjusting nut 7, the front end of adjusting nut 7 promote pad 6 extruding rubber rings 3.
Wherein, adjusting nut 7 is long nut, and rubber ring 3 can be selected other elastic materials such as silica gel, and strut 2 is the spring steel strut.
As shown in Figure 3, in actual applications, rotation adjusting nut 7 withstands pad 6, and pad 6 is contacted with rubber ring 3, and adjusts the frictional force of contact.And rotation adjusting nut 7 can change the position of damped oscillator 4 on strut 2, the vibration frequency of damping adjusting oscillator.
Since grinding worktable axial rigidity a little less than, when flutter was about to occur, damper suppressed axial vibration as absorbing mechanism, consumed the energy that flutter produces, and then the machining accuracy of assurance engineering ceramics, effectively avoid flutter and improve machine cut efficient.
More than be an embodiment of the present utility model, enforcement of the present utility model is not limited to this.
