It can be directed to different shockproofnesses simultaneously, respectively provide the damping performance of varying strength, it is ensured that machine tool is during the work time
Play effective damping effect.
4 left and right settings of first cutter hub 3 and the second cutter hub, the first cutter hub 3 and the second cutter hub 4 are along longitudinal direction from cutter head 2
It stretches out, and the length that the second cutter hub 4 stretches out is greater than the length that the first cutter hub 3 stretches out, the first cutter hub 3 and the second cutter hub 4 are ordinatedly
It is inserted in cutter head 2, cutter head 2 is equipped with the fastening screw 17 for compressing the first cutter hub 3 and the second cutter hub 4, is additionally provided with and is used on cutter head 2
It withstands the first of the first knife bar rear portion and adjusts screw 14, the front end of the second adjusting screw 18 is spun in the rear portion of the second cutter hub 4, the
The rear end of two adjusting screws 18 is spun in cutter head 2, and the second front end for adjusting screw 18 is the first screw thread 15, and second adjusts screw 18
Rear end be the second screw thread 16, and the screw pitch of the second screw thread 16 be slightly larger than the first screw thread 15 screw pitch, the first screw thread 15 and second
The rotation direction of screw thread 16 is identical, and first adjusts coarse adjustment of the screw 14 for relative length between the first cutter hub 3 and the second cutter hub 4, slightly
The fastening screw 17 for finishing and tightening corresponding first cutter hub 4 is adjusted, second, which adjusts screw 18, is used for fine tuning, and second adjusts screw rotation one
Week, the amount of movement of the second cutter hub 4 are the pitch difference of the second screw thread 16 and the first screw thread 15, and smaller second cutter hub 4 of pitch difference is mobile
Adjusting it is finer.
The present invention is affected by vibrations during tool sharpening can be greatly reduced, and effectively avoids the production of shake knife phenomenon
It is raw, guarantee machining accuracy, extend the stage property service life, and can easily adjust between the first cutter hub and the second cutter hub it is opposite away from
From.
The working principle of the invention is: being added after being fastened in the insertion mounting base 9 of knife bar 1 by bolt when use
Work, during processing, vibration caused by lathe tool can effectively be absorbed by absorbing joint 7 and damping circular arc 6, be subtracted simultaneously
Shake circular arc 6 plays good damping effect because deformation caused by damping will further be absorbed by impact-absorbing medium 8, and
It is not in the problem of damping effect caused by the excessive deformation of damping circular arc 6 reduces, lathe tool can be because of friction in process
High temperature is generated, sets silica gel piece for impact-absorbing medium 8, and silica gel has good high temperature resistant property, so can be effective
Impact-absorbing medium 8 is avoided the problem that because damping effect caused by high temperature melt deformation reduces；The vibration generated when tool sharpening has
