Be provided with the pin hole 11 of Φ 5mm on the knife bar 6, knife bar 6 is connected by Φ 5mm knife bar pin 7 with shaft coupling back segment 3, and referring to Fig. 4, Fig. 5 and Fig. 5 a, knife bar pin 7 is adjacent to the semi circular surface of special shape gap 5 and cooperates during work.Knife bar 6 can carry out low-angle (3 °) rotation along knife bar pin 7, realizes shaft coupling floating on knife bar 6 swaying directions by shaft coupling self length amplification, and amount of floating is 2.3mm.Can when design, control the amount of floating of this direction in the practical application by the length that changes gap length and shaft coupling.Because two unsteady directions are mutually vertical and independent, this shaft coupling can be implemented in floating of 0-1.2mm on any direction radially.
Shaft coupling realizes that Cusparia main shaft and cutter spindle are to circumferential gapless driving.Referring to Fig. 4 a, the special shape gap 5 of shaft coupling back segment 3 cooperates with knife bar pin 7, and knife bar pin 7 and shaft coupling do not break away from when guaranteeing feed and withdrawing with 45 ° of helical angles.Be same turning to during Cusparia feed withdrawing, this is the basis that shaft coupling is realized fast-assembling.During feed, the power of 7 pairs of shaft couplings of knife bar pin is Fx, Fy, their F that makes a concerted effort to be
Close, direction is shown in Fig. 4 a, and the semi circular surface that resultant direction contacts with shaft coupling by knife bar pin 7 is so can realize stablizing feed.During withdrawing, knife bar pin 7 is for the power of shaft coupling
They make a concerted effort be
Direction is not cut during withdrawing shown in Fig. 4 a,
Very little, so the semi circular surface that resultant direction contacts with shaft coupling by knife bar pin 7 equally can realize stablizing withdrawing.
Knife bar 6 is by rotation, insertion and rotate, pull out the realization installation and removal, need not the instrument dismounting.So shaft coupling can be realized the Fast Installation dismounting in small space.
Fastening iron wire 4 is No. 20 iron wires, diameter 0.9mm.Binding after pin 2 inserts in the shaft coupling prevents that pin 2 from coming off.
