Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
Fig. 1 to Fig. 3 is referred to, the utility model, which provides, is used for the device for connecting main shaft and oil cylinder on a kind of Digit Control Machine Tool,
Main shaft 2 including pedestal 1, in pedestal 1, the one end of main shaft 2 are connected with the chuck 3 in the side side wall of pedestal 1, main shaft
2 other ends run through the opposite side side wall of pedestal 1, and one end that the main shaft 2 runs through pedestal 1 is provided with mounting flange 4；The fixation
Flange 4 is provided with some through holes 5 being circularly and evenly distributed；The outside of mounting flange 4 is provided with some be circularly and evenly distributed
Fixed block 6, be spaced apart between fixed block 6 and through hole 5；The outside of fixed block 6 is equipped with a cushion 7；The elasticity
Pad 7 is provided with a groove 8；Shock relieve vent 9 is provided with the fixed block 6；The shock relieve vent 9 is passed through by bellmouth 10 and the phase of groove 8
It is logical；The beam 11 to match with it is installed in the groove 8；The inner side of beam 11 extends towards the direction of shock relieve vent 9
Go out a guide pad 12 to match with bellmouth 10, guide pad 12 and beam 11 are all quality of rubber materials；Pacify in the shock relieve vent 9
Equipped with damping spring 13；Described one end of damping spring 13 presses on the bottom of shock relieve vent 9, and the other end is pressed on guide pad 12；Institute
State both sides on fixed block 6 and be provided with the stroke groove 14 to be connected with bellmouth 10；The both sides of guide pad 12 are provided with and stroke groove 14
The decoupling rod 15 to match；It is connected between adjacent fixed block 6 by elastic webbing 16, elastic webbing 16 is individually fixed in phase each other
To decoupling rod 15 on；The elastic webbing 16 is provided with the connection ring 17 corresponding with the position of through hole 5；Set in the connection ring 17
There is perforation 18,18 diameters of perforation are equal to or more than the diameter of through hole 5.
Some elastics 19 being circularly and evenly distributed are provided with the shock relieve vent 9, elastic 19 encloses damping spring 13
Including conjunction；Described one end of elastic 19 presses on the bottom of shock relieve vent 9, and the other end is pressed on guide pad 12.
Application method of the present utility model is as follows：
When needing to be attached main shaft 2 and oil cylinder, oil cylinder junction is fitted on mounting flange 4, then passes through oil
The through hole 5 on connecting hole and mounting flange 4 on cylinder junction is installed bolt, so as to complete main shaft 2 and oil cylinder
Fixed, due to the presence of connection ring, therefore elastic webbing 16 will not be installed to bolt and cause to hinder, and bolt can sequentially pass through oil cylinder company
The connecting hole in place, the perforation 18 in connection ring 17, the through hole 5 on mounting flange 4 are connect, bolt is carried out finally by nut tight
Gu because mounting flange 4 is provided with some through holes 5 being circularly and evenly distributed, therefore the link position between main shaft 2 and oil cylinder
Extremely more, when formation pressure causes compressing each other, multiple link positions can share pressure jointly, so as to weaken each connection position
The pressure suffered by reality is put, the pressure after reduction can not then have any impact to each link position, fully belong to bear model
Enclose, so as to ensure that oil cylinder and the junction of main shaft 2 are not in be broken the situation for causing to be disengaged from, and mounting flange 4 itself
A large amount of pressure can be undertaken, final distribution to the pressure of each link position can then become smaller, ensure to the full extent oil cylinder 0 with
The steadiness of the junction of main shaft 2.
When main shaft 2 is run and produces vibrations, this strand of shaking force can be then influenceed to oil cylinder, and now main shaft 2 is transferred to oil cylinder
On shaking force then cushion 7 can be caused to extrude, during being extruded, cushion 7 carries out first slow to shaking force
Punching, a part of shaking force is set to be eliminated by the elastic buffer of cushion itself, and when cushion 7 is extruded, beam 11 is therewith
It is extruded, and as beam 11 is extruded, guide pad 12 is equally extruded, now beam 11 and guide pad 12 are all by certainly
The elasticity of the quality of rubber materials of body carries out bumper and absorbing shock to the shaking force not eliminated.
Guide pad 12, can be along the track of bellmouth 10 towards the direction of shock relieve vent 9 in the case where being extruded by beam 11
Mobile, now damping spring 13 is compressed, due to shaking force and non-constant, therefore damping spring 13 can do therewith opening shrink it is dynamic
Make, so as to further enter row buffering elimination, the shake that beam 11, guide pad 12 and damping spring can not all eliminate to shaking force
Power can be then transferred on elastic webbing 16 by the decoupling rod 15 on guide pad 12, and elastic webbing 16 is connected ring 17 and is fixed on
Determine between block 6 and bolt, therefore the shaking force that main shaft 2 is transferred on mounting flange 4 can be also transferred on elastic webbing 16 therewith, and
Undulatory motion then occurs in elastic webbing 16 under the influence of shaking force, and shaking force dissipates in atmosphere gradually.
In summary understand, the utility model can by cushion 7, beam 11, guide pad 12, damping spring 13 and
Elastic webbing 16 can form multiple tracks buffering, carry out bumper and absorbing shock to the full extent to shaking force, make shaking force can not be to main shaft 2
Rotation have any impact, so as to avoid main shaft 2 due to vibrations cause it is eccentric cause the bad situation of machining accuracy, ensure plus
Working medium amount.
Some elastics 19 being circularly and evenly distributed are provided with shock relieve vent 9, damping spring 13 is enclosed in by elastic 19
Interior, the one end of elastic 19 presses on the bottom of shock relieve vent 9, and the other end is pressed on guide pad 12, and elastic 19 can play auxiliary
The effect of damping, damping effect is improved, and the presence of elastic 19 can share pressure and the auxiliary damping of damping spring 13
Spring 13 resets, and avoids damping spring 13 from being oppressed the situation for causing elastic fatigue for a long time, and extend damping spring 13 uses the longevity
Life.
