Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Fig. 1 to Fig. 6 shows a kind of embodiment of the handle of a knife that the utlity model has dynamic balance adjusting structure, this has the handle of a knife of dynamic balance adjusting structure, comprise handle of a knife installation portion 1 and cutter holding portion 2, cutter holding portion 2 is provided with annular groove 4 near the outer rim of handle of a knife installation portion 1 one end, in cutter holding portion 2, be arranged with ring cover 3, the inwall of ring cover 3 and annular groove 4 form sealing track 6, in sealing track 6, be provided with balance ball 7, by the sealing track 6 of a sealing is set in the cutter holding portion 2 at handle of a knife, at the interior placement balance ball 7 of sealing track 6, make its freely-movable, thereby adjusting computing ballance correction, ensure handle of a knife stable working in the time of High Rotation Speed, improve the service life of machining accuracy and cutter, directly in the cutter holding portion 2 of handle of a knife, dynamic balance adjusting structure is set, have simple in structure, accessory is few, advantage easy for installation.
As shown in Figure 3, due to the existence in handle of a knife mass unbalance district 21, cause handle of a knife barycenter 23 to depart from handle of a knife pivot 22, when handle of a knife is in High Rotation Speed process, the acceleration that the frictional force of balance ball 7 and sealing track 6 provides balance ball 7 to circle, in the time reaching poised state, balance ball 7 is consistent with shank angle speed, and acceleration is zero, balance ball 7 and sealing track 6 between without relative motion, the frictional force that balance ball 7 gravity provide is zero, now handle of a knife is only subject to the centrifugal force and the reaction force that maintains balance ball 7 centripetal force in handle of a knife mass unbalance district 21 dorsad on horizontal plane, both balances, this reaction force points to 21 centers, handle of a knife mass unbalance district, therefore after reaching poised state, balance ball 7 can be stabilized in handle of a knife mass unbalance district 21, thereby adjusting computing ballance correction, ensure handle of a knife working stability in the time of High Rotation Speed, improve the service life of machining accuracy and cutter.In real work, can be according to the unbalanced situation of handle of a knife quality, the quality and quantity that increases or reduce balance ball 7 regulates the balance of the handle of a knife in the process of running up.
In the present embodiment, annular groove 4 comprises left side wall 41, right side wall 42 and diapire 43, left side wall 41 is higher than right side wall 42, ring cover 3 one end are against left side wall 41, left side wall 41 offers seal groove 5 with the junction of ring cover 3, in seal groove 5, be provided with sealing ring 51, improve the sealing of sealing track 6.
In the present embodiment, the inwall of ring cover 3 is threaded with the outer rim of cutter holding portion 2, and the inwall that ring cover 3 is corresponding with annular groove 4 is provided with draw-in groove 31, and draw-in groove 31 forms sealing track 6 with annular groove 4, the volume that increases sealing track 6, facilitates installation and the replacing of balance ball 7.
The span of balance ball 7 diameters is 1mm～15mm, and in the present embodiment, the diameter of balance ball 7 is 3mm.
In the present embodiment, balance ball 7 is made for having high density solid material, and quantity is 5.
