Part description: 1. the milling cutter rod comprises a milling cutter rod body, a cutter rod sleeve I, a nut I, a fixing sleeve I, a three-edge milling cutter I, a sleeve ring I, a three-edge milling cutter II, a sleeve II, a locking sleeve 10, a nut II, a cutter rod sleeve 12, a flat key 13 and a cutter rod nut 14.
Detailed Description
For a better understanding and implementation, the present invention is further described below with reference to the accompanying drawings: finish milling spline micromatic setting, including milling cutter arbor 1, install tool bar cover I2 on the milling cutter arbor 1, be equipped with fixed cover 4 on the milling cutter arbor 1, fixed cover 4 is located tool bar cover I2 inboard, fixed cover 4 inboard is equipped with lock sleeve 10, be equipped with trilateral sword milling cutter I6 between fixed cover 4 and the lock sleeve 10, fixed cover 4, lock sleeve 10, be equipped with flat key 13 between trilateral sword milling cutter I6 and the milling cutter arbor 1, be equipped with nut I3 on the fixed cover 4, fixed mounting has cover I5 between nut I3 and trilateral sword milling cutter II 8, be equipped with trilateral sword milling cutter II 8 on the lock sleeve 10, be equipped with nut II 11 on the lock sleeve 10, fixed mounting has cover II 9 between nut II 11 and the trilateral sword milling cutter II 8, lock sleeve 10 one side is equipped with tool bar cover II 12, be equipped with cutter bar nut 14 between tool bar cover II 12 and the one end of milling cutter arbor 1, be equipped with lantern ring 7 on the lock sleeve 10.
The three-side edge milling cutter I6 and the three-side edge milling cutter II 8 are different in inner hole structure, the inner hole of the three-side edge milling cutter I6 is provided with a common flat key groove and a spline groove, the inner hole of the three-side edge milling cutter II 8 is provided with only the spline groove, and the fixing of the three-side edge milling cutter I6 is completed through the fixing sleeve 4, the locking sleeve 10, the cutter bar nut 14 and the cutter bar sleeve II 12. The three-sided milling cutter i 6 is fixed and is fixed all the time by tightening the cutter bar nut 14. The distance between the inner side edges of the three-edge milling cutter I6 and the three-edge milling cutter II 8 is adjusted by the nut I3, the sleeve I5, the sleeve II 9 and the nut II 11 to move and fix the three-edge milling cutter II 8. The outer circles of the nut I3 and the nut II 11 are provided with spanner holes, scales and numbers, each Shan Xiaoge is 0.02 millimeter, and the outer circles of the sleeve I5 and the sleeve II 9 are respectively provided with a finger line. The collar 7 only plays a binding role, and two sides of the collar are separated from the inner side edges of the three-edge milling cutter I6 and the three-edge milling cutter II 8 by a large distance. The fixed sleeve 4, the sleeve I5, the three-edge milling cutter I6, the three-edge milling cutter II 8, the sleeve II 9 and the locking sleeve 10 are mutually inserted through a spline-like structure.
The specific fine tuning mode is as follows: when the three-edge milling cutter II 8 needs to be moved in a fine-tuning mode to the left, after the nut I3 is loosened slightly, the nut II 11 is rotated to move to the left, the scales on the outer circle are seen to be rotated to required values, and then the nut I3 is screwed. On the contrary, when the three-edge milling cutter II 8 needs to be moved in a fine-tuning way to the right, after the nut II 11 is loosened slightly, the nut I3 is rotated to move to the right, the scales on the outer circle are seen to be rotated to the required values, and then the nut II is screwed.
Because of single-blade fine adjustment movement, in order to enable the width dimension of the milled key to be symmetrical to the axis of a workpiece, after fine adjustment movement of the three-edge milling cutter II 8, a dial indicator seat is sucked on a transverse guide rail plane of equipment, an adjusting table column is pressed to a certain value on the side surface of a workbench, and the rotation value of a watch needle of the transverse movement workbench is half of that of the fine adjustment of the three-edge milling cutter II 8. The direction of the transverse moving workbench is consistent with the direction of the fine-tuning three-edge milling cutter II 8. Thus, the required precision can be achieved.
When the fine milling spline fine adjustment device is used for adjusting the width of a key, a milling machine hanging frame, milling cutters and a cutter bar sleeve do not need to be detached, a plurality of cutter isolating washers with small thickness difference do not need to be prepared, and only the nut I and the nut II need to be rotated, so that the distance between the two milling cutters is adjusted, and the distance meets the requirement of the width of the spline key. The operation is simple and the efficiency is high.
