The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in accompanying drawing 1, this boring and milling machine spindle taper hole conversion equipment comprises tapered sleeve 14, tapered sleeve 14 tail end inner hole thread fixed supports cover 4, support set 4 holes are built-in with adapter sleeve 5, adapter sleeve 5 endoporus are fixed with main shaft blind rivet 3 outer-diameter threads of passing support set 4 centre bores, and the fixing right-hand member of push rod 7 of the inner hole thread of main shaft blind rivet 3, and push rod 7 is the multidiameter type, middle part and left end have the shaft shoulder 15 and the middle shaft shoulder 17 respectively, at two shaft shoulders (17,15) clamp the root of claw 9 on Zhong Jian the diameter, the be threaded endoporus of taper tool shanks 13 of the head of a nail of the claw clamping blind rivet 10 of claw 9, the nail bar of blind rivet 10; The right side of the shaft shoulder 17 is equipped with pad 6 and touches mutually with the left side of main shaft blind rivet 3; Be equipped with spring 8 between the interior shoulder hole of support set 4 and the external diameter of adapter sleeve 5; Tapered sleeve 14 is fixed on the main shaft by overlapping 11 by bolt 12, and the male cone (strobilus masculinus) of tapered sleeve 14 and support set 4 and main shaft internal taper hole coincide; Be equipped with sealing ring 16 between adapter sleeve 5 endoporus and claw 9 root external diameters.
When needs are changed the cutter of ISO50 type taper shank, this boring and milling machine spindle taper hole conversion equipment is advanced in the ISO60 type milling-boring machine spindle taper hole, when the big end of tapered sleeve moves to the big end of spindle taper hole, because of two equal diameters, tapered sleeve is no longer motion axially, for being synchronized with the movement, this device and main shaft do not produce relative rotation, with screw 12 tapered sleeve 14 is fixed on the main shaft, for preventing the taper hole distortion, screw 12 is fixed on tapered sleeve 14 on the main shaft by lining 11, lining 11 exceeds 0.1-0.2mm than screw hole circular bead surface, exceed 2-3mm than the right circular bead surface of tapered sleeve, make to keep the 0.1-0.2mm gap between screw 12 and screw hole circular bead surface, keep the 2-3mm gap between right circular bead surface of tapered sleeve and main shaft end face.When the loose cutter button on the push panel, push rod on the main shaft in the loose knife oil cylinder promotes knife bar 1, knife bar 1 promotes main shaft jaw 2 simultaneously, main shaft jaw 2 opens when moving 7.5mm, be in the cutter state for the treatment of, main shaft blind rivet 3, adapter sleeve 5, pad 6 and push rod 7 link together, under the promotion of spring 8, just make their mobile simultaneously 8mm like this, push rod 7 promotes jaws 9 at this moment, when push rod 7 moves 7.5mm, and the mobile simultaneously 7.5mm of jaw 9, this moment, jaw 9 opened, be in the cutter state for the treatment of, push rod 7 also contacts with blind rivet 10, and at this moment push rod 7 continues mobile 0.5mm, touch blind rivet 10, because of 10 be with taper tool shanks 13 are the all-in-one-pieces that are threaded, taper tool shanks 13 is deviate from from spindle taper hole like this, can realize loose cutter.Adapter sleeve 5 and blind rivet 3 put together on together, and its motion and blind rivet 3 are synchronous, are against in empty cutter left side on the loose cutter location end face 18 of tapered sleeve endoporus, prevent that jaw 9 and blind rivet 3 from deviating from.When need changing the different cutter of ISO50 taper shank, the operator only needs blind rivet 10 is tightened on the taper tool shanks 13 in advance, be in when treating the cutter state, can push ISO50 type taper tool shanks together with blind rivet 10, dress cutter button on the push panel just can be installed in cutter in the taper hole of tapered sleeve 14 easily then, has realized utilizing ISO60 type milling-boring machine spindle taper hole that the cutter of ISO50 type taper shank is installed, need not lay down the conversion sleeve device, time saving and energy saving, raise the efficiency.
