Referring to fig. 2, in the present embodiment, ram 2 is in that similar " cuboid " shape is arranged, inside, it is provided with for band moving knife
Has the main shaft 1 of rotation, main shaft 1 is fixedly connected with ram 2；Power source drive ram 2 moves up and down it from saddle 3, thus
Main shaft 1 is driven to move along Z-direction, so as to be equipped with the live spindle 1 of corresponding cutters to the graphite workpiece being located on workbench
Carry out machining.
The live spindle 1 of corresponding cutters is installed during processing graphite workpiece, since main shaft 1 is in the drive of power source
Dynamic lower high speed rotation, when contacting with graphite workpiece, will generate biggish active force；The active force will act on solid with main shaft 1
Surely on the ram 2 connected, cause ram 2 in the movement of X-axis and/or Y direction, influence the stability of main shaft 1, to reduce stone
The processing quality of black workpiece.
For this purpose, the reference for assembling in technical solutions of the utility model by the one side wall 32 of saddle 3 as ram 2 and saddle 3
Face, and in assembly ram 2 and saddle 3 in being close to be arranged；And it is provided with and is used in the saddle of the opposite side of the assembling base plane 3
First panel 42 of limit.Since the side of ram 2 is in be close to setting with saddle 3, so that ram 2 is in the direction towards the side wall 32
On can not generate displacement；Meanwhile the first panel 42 being arranged on the opposite side of the side wall 32 is in become placed against with ram 2, can be made
Displacement can not be generated on the direction towards opposite side side wall 32 by obtaining ram 2.In this way, being close to saddle 3 and the first panel by ram 2
42 setting can effectively limit ram 2 in the movement of X-direction.
Meanwhile to limit ram 2 in the movement of Y direction, technical solutions of the utility model are arranged between two sidewalls 32
There is the pressing plate 41 for compressing ram 2.Referring to Fig. 1, in the Y-axis direction, the back inner wall of saddle 3 is in when connecting with ram 2
It becomes placed against, ram 2 is towards can not generate displacement on the inner wall direction；And the pressing plate 41 being arranged, it is also in be close to set with ram 2
It sets, it is ensured that ram 2 can not generate displacement on the direction towards the pressing plate 41.In this way, limitation ram 2 can be realized in Y-axis side
To movement.
In summary, technical solutions of the utility model can effectively limit ram 2 in the movement of X-axis and/or Y direction,
Guarantee that ram 2 is only moved up and down along Z-direction, to enhance the stability of main shaft 1 in process, to improve graphite workpiece
Processing quality.
Technical solutions of the utility model are internally provided with the ram 2 moved up and down for controlling main shaft 1, the cunning in saddle 3
The one side wall of pillow 2 and the side wall 32 of saddle 3 are adjacent to；And first for limit is provided on another opposite side inner wall of saddle 3
Panel 42, which is in become placed against with ram 2, so that main shaft 1, during workpieces processing, ram 2 exists
Twisting will not be generated on 32 direction of two sidewalls of saddle 3.Meanwhile it being provided between 3 two sidewalls 32 of saddle for compressing ram 2
Pressing plate 41；When the pressing plate 41 can effectively prevent main shaft 1 from processing, the ram 2 caused by it is vibrated is along vertical pressing plate 41
The twisting in direction.In this way, technical solutions of the utility model can effectively limit the movement in other directions of ram 2, make it only
Linear motion up and down is done along Z-direction, to enhance the stability of main shaft 1, improves the processing quality of workpiece to be processed.
In one preferred embodiment of the utility model, positioning component 4 further includes at least groove 411 on pressing plate 41
And the second panel 43 to match with an at least groove 411, the second panel 43 are inserted in groove 411, for adjusting ram 2
With the gap between the second panel 43 so that ram 2 is compressed by pressing plate 41.The mistake that ram 2 moves up and down in saddle 3 along Z axis
Cheng Zhong, ram 2 are contacted with pressing plate 41 back and forth, will inevitably generate friction；For a long time, will ram 2 and pressing plate 41 it
Between generate gap so that in Y direction a degree of loosening occurs for ram 2, to influence the stability of main shaft 1.For this purpose,
The structure of the second panel 43 with groove 411 is added on pressing plate 41, with by the second panel 43 adjust ram 2 and the second panel 43 it
Between gap so that pressing plate 41 compress ram 2.It is symmetrical that two are offered on pressing plate 41 as a preferred embodiment referring to Fig. 3
The groove 411 of setting, the size and shape of the groove 411 match with the second panel 43；When assembly, the second panel 43 is plugged in
In groove 411, the pressing plate 41 for being inserted with the second panel 43 is fixed to by 3 bottom of saddle by screw.If the second panel 43 and cunning
Gap is generated between pillow 2, leads to the loosening of ram 2 in the Y-axis direction；Since the contact surface of the second panel 43 and pressing plate 41 has
Therefore constant slope can be adjusted between the second panel 43 and ram 2 by the adjusting screw being arranged on the second panel 43
Gap.In this way, the movement of ram 2 in the Y-axis direction can be further prevented, to guarantee the stability of main shaft 1.
In the utility model another preferred embodiment, the contact face paste of the first panel 42 and the second panel 43 and ram 2
Equipped with guide-soft-band (not shown).It, will be inevitably between the first panel 42 and the second panel 43 due to the movement of ram 2
Friction is generated, to reduce friction, the guide rail that can be sticked respectively on the contact surface of the first panel 42 and the second panel 43 and ram 2 is soft
Band, the i.e. laminating operation on panel surface.Plastic-sticking guiding rail is that polytetrafluoroethylene (PTFE) guide-soft-band is bonded in guide rail meter using bonding agent
Face, so that the friction type of conventional guide rails becomes cast iron-plastic friction pair.Polytetrafluoroethylene (PTFE) guide-soft-band has stronger wear-resisting
Performance and damping property, since in polytetrafluoroethylene (PTFE) guide-soft-band material, itself has lubricating action, therefore, to lubrication
Fuel delivery is of less demanding.
