Detailed description of the invention
See accompanying drawing, a kind of demountor for dismantling end cap in the mining column of horizontal snap ring-type, include and be arranged on slide 1 corresponding with workpiece 9 to be torn open on horizontal column workbench, one end of slide 1 is installed with cutter assembly 2, cutter assembly 2 includes overcoat 3, tapered sleeve 4 and cutter fixed cover 5 is installed with in overcoat, the front end face circle distribution of cutter fixed cover 5 has several cutter 19, cutter fixed cover 5 is provided with pilot hole, thereafter the lower surface of end is provided with taper activity chamber, baffle ring 20 is provided with above its leading section and between overcoat 3 inner ring, tapered sleeve 4 one end is arranged in taper activity chamber, tapered sleeve 4 leading section is by inserting bearing pin 14 and overcoat 3 secure fit in pilot hole, tapered sleeve 4 and cutter fixed cover 5 inner ring are provided with guide ring 11, 12, tapered sleeve 4 is also provided with handle 6, overcoat 3 is provided with handle 6 loose slot, overcoat 3 is also provided with cutting jack driving bar 7, the other end of slide 1 is driven by the jack 8 that works, the inner ring of overcoat 3, the inner face of cutter 19 and guide ring 11, 12 coordinate with the periphery of workpiece 9 to be torn open, slide 1 is the dolly of middle part band square hole, and the dual-side of dolly is respectively equipped with roller, and the front end face of slide 1 is installed with and drives cutter to rotate, cutter assembly 2 overcoat 3 rearward end is provided with groove 18, and inserts groove 18 by plate 13 and cutter assembly 2 and slide 1 are fixedly mounted, cutter are 16, are distributed on the front end face of cutter fixed cover 5, and its root and cutter fixed cover 5 are integral type structure, and the cutter tooth of cutter is double-sided blade, handle 6 loose slot is helicla flute, cutting jack 10 is hydraulic jack, and its piston rod external part fixedly mounts with cutting jack driving bar 7.
In FIG, when work jack 8 does extend action, promote dolly and be moved to the left.The dust-proof seal ring 15 approached on workpiece is moved to the left by the cutter assembly 2 of two plate 13 pushing sleeves on the workpiece body of rod be inserted in dolly square hole and cutter assembly 2 groove.Start cutting jack 10 to stretch out, regain action, promote cutter assembly 2 and do clockwise, counterclockwise reciprocating rotary action.It is cutting centripetal force that time liquid back pressure during cutting jack 10 action formed by hydraulic system of the present invention makes work jack 8 do the relatively little masterpiece of extend action generation.Realize the excision to dust-proof seal ring 15 partial rubber.By the structure of cutter assembly 2 self, cutter tooth is opened again, start work jack 8 and do withdrawal action, end cap 16 is pulled out from column 17.
In Fig. 2,3, cutter 19 are the cutter making a groove and root connection.Individual cutter tooth is all double-sided blade, is made with the anterior angle being applicable to cutting elastomeric material.When overcoat 3 rotates, cutter are driven to rotate by bearing pin 14.The centripetal force formed by the machine makes cutter assembly 2 entirety be moved to the left cutting dust-proof seal ring 15.When the bossing of dust-proof seal ring 15 is cut, after the point of a knife of cutter 19 crosses the inner face of end cap 16, move handle 6, owing to opening the spiral fluted effect on overcoat 3, handle 6 drives tapered sleeve 4 to be moved to the left.Bar because of handle 6 is in the groove of cutter, and cutter can not do movement left.There is the effect of the male cone (strobilus masculinus) of tapered sleeve 4 and cutter inner conical surface that 16 of cutter cutters tooth are opened simultaneously.At this moment, the work jack 8 starting the machine is done to regain action, is pulled out by cutter assembly 2 together with end cap 16 from column.After end cap 16 departs from column, oppositely move handle 6, drive the relative cutter of tapered sleeve 4 to move right, make its male cone (strobilus masculinus) depart from cutter.Drive again baffle ring 20 to move right, the effect of being paid by another cone match, makes 16 of cutter cutters tooth retract simultaneously, takes off end cap 16 simultaneously.
In the diagram, the cutting jack 10 be arranged on dolly does and stretches out, when regaining action, drive the handle having elongated slot on cutter assembly 2 and make cutter assembly 2 reciprocating rotary.
