Abstract
The invention provides a quick replacing device of milling cutter rods. The quick replacing device comprises milling cutters, the milling cutter rods and pull rods, wherein the milling cutters are fixedly connected with the milling cutter rods through tension bolts and washers; the pull rods and transition sleeves are fixedly connected to a main shaft of a milling machine through threads; the transition sleeves are provided with locking nuts; gaps in the hole walls of the locking nuts are aligned to gaps in the end surfaces of the transition sleeves; the milling cutter rods are mounted in the transition sleeves; and convex keys on the milling cutter rods are aligned to the locking nuts and the gaps in the transition sleeves. The device has the advantages of convenience for operation, low labor intensity and high working efficiency. Different components are machined only by replacing the milling cutter rods.
Description
Technical field
The present invention relates to mechanical field, relate in particular to fast replacing milling cutter lever apparatus.
Background technology
When originally same workpiece difference key element processed by milling machine, without special purpose device, the following method of general employing: knife bar 7:24 male cone (strobilus masculinus) is loaded in main shaft 7:24 internal taper hole along milling machine spindle hole, and by the key on two notch alignment main shaft end faces on the flange of knife bar shank rear end, in inner hole of spindle, pull bar is housed, screwed in by pull bar in knife bar shank internal thread, knife bar is fixed on main shaft by tensile ties.To tightening nut be unclamped when processing next key element, screw off pull bar, change another knife bar, repeat above-mentioned action retighten.Often process a key element and all heavily will change a knife bar, operate the lay day so long, labour intensity is large, production efficiency is low.
Summary of the invention
The invention provides a kind of fast replacing milling cutter lever apparatus, solve the shortcoming that in background technology, manual setting method labour intensity is large, the operating time is long, production efficiency is low.
Technical scheme of the present invention is achieved in that fast replacing milling cutter lever apparatus, comprise milling cutter, milling arbor, pull bar, milling cutter is fixedly connected with milling arbor by turnbuckle, packing ring, pull bar and spacer shell are fixedly connected on milling machine spindle by screw thread, spacer shell is equipped with locking nut, breach on notch alignment spacer shell end face on locking nut hole wall, milling arbor is positioned in spacer shell, and the convex key on milling arbor aims at the breach on locking nut and spacer shell.
The invention has the beneficial effects as follows: the present invention is when the different key element of the same workpiece of milling, first quick change spacer shell is fixed on milling machine spindle by pull bar, different milling cutter is arranged on different milling arbor, and strain with turnbuckle, milling cutter is loaded together with milling arbor in quick change spacer shell, screw locking nut, milling arbor is pressed on quick change spacer shell by nut inner hole plane.When changing cutter, only need unscrew locking nut, make the convex key on the notch alignment milling arbor on locking nut, jiggle milling arbor, it is taken out in the axial direction in quick change spacer shell, changes required another set of milling cutter and milling arbor simultaneously, screw locking nut.This device is easy to operate, and labour intensity is low, and operating efficiency is high, processes different key element and only need change milling arbor.
Accompanying drawing explanation
Fig. 1 is generalized section of the present invention.
Part illustrates: 1, milling cutter, 2, milling arbor, 3, locking nut, 4, quick change spacer shell, 5, turnbuckle, 6, packing ring, 7, pull bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described: fast replacing milling cutter lever apparatus, comprise milling cutter 1, milling arbor 2, pull bar 7, milling cutter 1 is by turnbuckle 5, packing ring 6 is fixedly connected with milling arbor 2, pull bar 7 and spacer shell 4 are fixedly connected on milling machine spindle by screw thread, spacer shell 4 is equipped with locking nut 3, locking nut 3 inner hole wall and spacer shell 4 end face all there are two symmetric windows, screw locking nut 3, make the breach on notch alignment spacer shell 4 end face on locking nut 3 hole wall, milling arbor 2 is held greatly on cylindrical has two convex keys to coordinate with the breach of spacer shell 4, convex key alignment notch on milling arbor 2 is put in spacer shell 4, screwing locking nut 3 is again fixed on spacer shell 4 by milling arbor 2, spacer shell 4 outer cone tapering is that 7:24 and milling machine spindle match, milling arbor 2 outer cone tapering and spacer shell inner cone tapering are 20 °, the two precision matches.
Spacer shell 4 is fixed on milling machine spindle by pull bar 7, and it is locked motionless, milling cutter 1 is arranged on (one is equipped with one milling arbor milling cutter) on milling arbor 2, and strain with turnbuckle 5, locking nut 3 is screwed on spacer shell 4, breach on notch alignment spacer shell 4 end face on locking nut 3 inner hole wall, the milling cutter 1 of needs and milling arbor 2 is selected to combine, convex key on milling arbor 2 is aimed at the breach on locking nut 3 and spacer shell 4, in the axial direction milling arbor 2 is put in spacer shell 4, convex key on milling arbor 2 coordinates so that transmitting torque with breach on spacer shell 4, screw locking nut 3 milling arbor 2 is compressed and is fixed on spacer shell 4, only locking nut 3 need be unscrewed when processing different key element, aim at the breach on locking nut 3 and milling arbor 2 and convex key, jog milling arbor 2, it is taken out in quick change spacer shell 4, change required another set of milling cutter 1 and milling arbor 2 combines simultaneously, screw locking nut 3.
