Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the present invention provides a kind of technical solution: a kind of machine tool shock-damping structure, including cutterhead frame sheet
The inside of body 1, cutterhead frame ontology 1 is equipped with support rod 3, and support rod 3 is fixedly connected with cutterhead frame ontology 1, the lateral wall of support rod 3
Equipped with dampening assembly 4, dampening assembly 4 is fixedly connected with support rod 3, and the left end of dampening assembly 4 is equipped with cutterhead 5, cutterhead 5 and cutterhead
Frame ontology 1 is fixedly connected by dampening assembly 4, and the top of cutterhead 5 is equipped with clump weight 6, and clump weight 6 is fixedly connected with cutterhead 5, knife
The left surface of disk 5 is equipped with knife rest 7, and knife rest 7 is fixedly connected with cutterhead 5, and knife rest 7 is equipped with dress cutter holder disk 8, fills cutter holder disk 8 and knife
Frame 7 is fixedly connected, and the inside of dress cutter holder disk 8 is equipped with cushion 9, and cushion 9 is fixedly connected with dress cutter holder disk 8, dress cutter holder disk 8
Inside offers card slot 81, and card slot 81 and dress cutter holder disk 8 are integrally formed.
In the present embodiment, the inside of dress cutter holder disk 8 offers card slot 81, and card slot 81 and dress cutter holder disk 8 are integrally formed, dress
Cutter holder disk 8 has certain magnetic, will to open up inside the top insertion dress cutter holder disk 8 of cutter card slot 81, and rotary cutter passes through spiral shell
Line structure is fixedly connected, and completes the installation fixed a cutting tool to dress cutter holder disk 8, and cushion 9 is rubber pad, can be to a certain degree
Contract, when processing the workpiece, the impact force being subject to is buffered cutter by cushion 9, prevents cutter from being broken by vibration
Knife.
In the present embodiment, the quantity of support rod 3 is four, and four support rods 3 are installed in the interior of cutterhead frame ontology 1
Portion, by outside disc around dampening assembly 4 shunk, the vibration being subject to that cutterhead 5 is fixed a cutting tool is buffered to cutterhead frame ontology 1
Outside mitigates cutter and is affected by vibrations.
Further, cutterhead frame ontology 1 is equipped with water inlet pipe 2, and water inlet pipe 2 is fixedly connected with cutterhead frame ontology 1.
In the present embodiment, cutterhead frame ontology 1 is equipped with water inlet pipe 2, be inside cutterhead frame ontology 1 it is hollow, pass through water inlet pipe 2
Cooling water is injected into cutterhead frame ontology 1, for the heat that cooling knife plate rail ontology 1 is subject to when in use, promotes cutterhead frame
The stability that ontology 1 uses.
Further, the left end of cutterhead frame ontology 1 is equipped with pilot pin 11, the one end and cutterhead of pilot pin 11 through cutterhead 5
Frame ontology 1 is fixedly connected.
In the present embodiment, the left end of cutterhead frame ontology 1 is equipped with pilot pin 11, and cutterhead 5 is mounted on knife by pilot pin 11
It is convenient that cutterhead 5 is installed on plate rail ontology 1.
Further, the quantity of clump weight 6 is four, and four clump weights 6 are installed in the lateral wall of cutterhead 5.
In the present embodiment, the quantity of clump weight 6 is four, and four clump weights 6 are installed in the lateral wall of cutterhead 5, match
Pouring weight 6 promotes the weight of cutterhead 5, prevents from occurring cutterhead 5 because the tool weight of 5 upper tool post 7 of cutterhead installation is different and sinking partially, mention
Cutterhead 5 is risen to fix a cutting tool stability when in use.
Further, the quantity of knife rest 7 is eight, and eight knife rests 7 are installed on cutterhead 5, and eight knife rests 7 are opened
If there are three fill cutter holder disk 8.
In the present embodiment, the quantity of knife rest 7 is eight, and eight knife rests 7 are installed on cutterhead 5, and eight knife rests 7 are equal
It opens up there are three cutter holder disk 8 is filled, dress cutter holder disk 8 makes for installing different cutters, different cutters for different processing technologys
With promoting the range of work of lathe.
As shown in Figure 4,5, dampening assembly 4 includes outer spring 101, inner spring 102, mounting base 103；
The outer spring 101, inner spring 102 are mounted between left and right mounting base 103, and mounting base 103 respectively symmetrically passes through bolt
It is mounted on 1 internal chamber wall of cutterhead frame ontology.
Left and right mounting base 103 is provided with raised deck 104 for preventing outer spring 101 from lateral displacement, outer spring occurs
The diameter of 101 both ends rotation reduces the both ends for being pressed on inner spring 102, i.e. 101 diameter D2 of outer spring diminution is transitioned into
The longitudinal movement of inner spring 102 can be effectively prevented in D1；Outer spring 101, inner spring 102 are reliably fixed in mounting base, reached
To the technical effect being reliably fixed, cutterhead 5 fix a cutting tool the vibration being subject to when, dampening assembly plays effective damping, buffering.Simultaneously
It will not reliably not fixed because of the spring itself of dampening assembly, cutter shakes, and and then vibration does not have not only spring yet
Damping, buffering is played, cutter is instead resulted in and accelerates damage.
Outer spring 101,102 radial section of inner spring are circular ring shape and structure is identical, the two of outer spring 101, inner spring 102
End is equipped with variable diameter jointing 108, is connected by variable diameter jointing 108 and connecting tube 106, and the connection of connecting tube 106 is logical
It crosses external connector 107 to connect with the liquid storage chamber 105 of mounting base 103, non-newtonian fluid is filled in liquid storage chamber 105.5 upper slitter of cutterhead
When having the vibration being subject to, shock loading is instantaneously cut down in the non-newtonian fluid antidamping inside outer spring 101, inner spring 102, quickly
A part concussion energy is absorbed, spring assembly vibration is when deformation occurs, since spring inner filling non-newtonian fluid slowly compresses
The characteristic flowed afterwards can be stable reduction duration shock loading.
Compared to traditional spring, due to being made of alloy memory metal outside spring, filling non-newtonian fluid in inside has two
Kind material composition, can absorb the jerk of different frequency.Spring intracavity fills non-newtonian fluid and compares traditional spring anti-wink
When impact property it is good, as the deformation non-newtonian fluid of spring slowly flows, antidamping effect is shown, can be directed to different impacts
Vibration, makes corresponding reduction, while providing the antidamping support of varying strength.
Outer spring 101, inner spring 102 different-diameter structure design, inner spring 102 be outer spring 101 support is provided,
It can be directed to different shockproofnesses simultaneously, the damping performance of varying strength is respectively provided, it is ensured that the metastable carry out work of cutter essence
Make.
The working principle of the invention and process for using: after the present invention installs, the inside of dress cutter holder disk 8 offers card slot
81, dress cutter holder disk 8 has certain magnetic, will to open up inside the top insertion dress cutter holder disk 8 of cutter card slot 81, rotary cutter,
It is fixedly connected by helicitic texture, completes the installation fixed a cutting tool to dress cutter holder disk 8, cushion 9 is rubber pad, can be one
Determine degree contract, when processing the workpiece, the impact force being subject to is buffered cutter by cushion 9, prevents cutter from being shaken
There is breaking, cooperation 3 outside disc of support rod around dampening assembly 4 shunk, the vibration being subject to of fixing a cutting tool of cutterhead 5 is buffered to
The outside of cutterhead frame ontology 1 mitigates cutter and is affected by vibrations, promotes machine tool stability in use.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
