Equipped with a partition plate 5；It is coniform elastic membrane 6 that 5 lower section of partition plate, which is equipped with one,；Extend one in the 6 lower section edge of elastic membrane
Beam 7 arranged on 4 lower section of under-chassis；A damping space annular in shape is enclosed between the partition plate 5, elastic membrane 6 and under-chassis 4
8；The 6 lower section middle part of elastic membrane is formed with a conical bore 9, and matched snubber block 10 is equipped in conical bore 9；It is described
4 bottom surface of under-chassis is equipped with a damping trough 11, and damping trough 11 is covered sealing by beam 7；A membrane 12 is equipped in the damping trough 11,
Membrane 12 is elastic material；Damping trough 11 is divided into upper chamber 13, lower chambers 14 by the membrane 12；The lower chambers 14 pass through
Venthole 15 connects with damping space 8；5 center of partition plate be equipped with a through hole 16,6 center of elastic membrane be equipped with
The perforation 17 that through hole 16 connects, conical bore 9 are connected by perforation 17 with through hole 16；The 10 upper center position of snubber block
Equipped with a standpipe 18；The 18 top nozzle of standpipe is equipped with a spacing ring 19；Matched limit is equipped in the standpipe 18
Position plate 20,20 diameter of limiting plate are more than 19 internal diameter of spacing ring；1 bottom centre position of lathe bed is equipped with a fixed link 21, fixed
Bar 21 is penetrated in standpipe 18 and is connected with limiting plate 20.
Anode magnetosheath 22 is arranged with outside the standpipe 18；22 upper surface of anode magnetosheath less than 5 upper surface of partition plate or with
5 upper surface flush of partition plate；The partition plate 5 is equipped with the cathode magnetic stripe 23 attracting with anode magnetosheath 22；The cathode magnetic stripe 23 is logical
Cross tension spring 24 with and its adjacent under-chassis 4 be connected.
Several elastic balls 25 are filled in the damping space 8.
The application method of the utility model is as follows：
When numerically controlled lathe starts, driving device 3 brings into operation, and processing unit (plant) 2 starts to add under the driving of driving device 3
Work, when driving device 3 brings into operation, driving device 3 can then generate shaking force, since driving device 3 is arranged on numerically controlled lathe bed
On body 1, therefore shaking force can be transferred directly on lathe bed 1.
Digital controlled lathe bed 1 is influenced by shaking force, is present with slight undulatory motion, and with its fluctuating, by shaking force
It is transferred towards its bottom, the shaking force on final lathe bed 1 is transferred in under-chassis 4 and fixed link 21, and the shaking force on under-chassis 4 is then
Beam 7 can be squeezed, beam 7 can then be formed by natural resiliency and buffered together, and the shaking force on under-chassis 4 is carried out
Bumper and absorbing shock makes a part of shaking force be eliminated, and the shaking force in fixed link 21 then can be transferred to snubber block by standpipe 18
On 10, snubber block 10, which is given a shock power, to be influenced then to shake when snubber block 10 is upward along the track vertical tremor of fixed link 21
When, then elastic membrane 6 can be squeezed, the elastic membrane 6 being squeezed can then generate elasticity, to the shaking force on snubber block 10 into
Row buffering damping.
As elastic membrane 6 is extruded, the air pressure in damping space 8 forms high pressure draught and is sprayed from venthole 15 with rise
Enter to lower chambers 14, when beam 7 is towards when being extruded in lower chambers 14, the air pressure in lower chambers 14 also increases, and subtracts
High pressure draught in shake space 8 can then liquidate with the high pressure draught in lower chambers 14, and lower chambers 14 are transferred to so as to consume
Interior shaking force and the shaking force being transferred in damping space 8, even if two strands of high pressure draughts, which liquidate, can not completely eliminate shaking force,
Remaining shaking force can then carry out membrane 12 upward, and the elastic force that the deformation of membrane 12 generates can then carry out this strand of shaking force
Bumper and absorbing shock, and as membrane 12 is upwardly-deformed, the air pressure rise in upper chamber 13, the high pressure of upper chamber 13 can then aid in membrane
12 pairs of further bumper and absorbing shocks of shaking force.
It understands in summary, the shaking force on lathe bed can be transferred to under-chassis 4 and snubber block 10 respectively by the utility model
On, then multiple tracks is formed by components such as beam 7, elastic membrane 6 and membranes 12 and buffered, shaking force is carried out maximum
Bumper and absorbing shock makes lathe bed be no longer influenced by the influence of shaking force, ensures that shaking force can not influence processing unit (plant) 2,2 energy of processing unit (plant)
That enough stablizes is processed workpiece, and the machining accuracy of processing unit (plant) 2 is made to be protected, realizes high-precision effect, can more be protected
Processing quality is demonstrate,proved, and with the elimination of the shaking force on digital controlled lathe bed 1, numerically controlled lathe vibrations can be avoided to cause ground
The situation of damage.
When snubber block 10 shakes upwards, originally it is less than 5 upper surface of partition plate or the anode magnetosheath with 5 upper surface flush of partition plate
22 move up, and are then flushed with cathode magnetic stripe 23, and cathode magnetic stripe 23 and anode magnetosheath 22 are attracting at this time, this strand of suction can then delay
The vertical tremor of slow snubber block 10, so as to play the effect of bumper and absorbing shock, and the presence of tension spring 24 can effectively help cathode magnetic
Item 23 resets.
Several elastic balls 25 are filled in damping space 8, when elastic membrane 6 is extruded, elastic ball 25 is extruded simultaneously, quilt
The elastic ball 25 of extruding can equally generate elasticity, so as to increase the elastic force of elastic membrane 6, improve the buffering and damping effect of elastic membrane 6.
