The specific embodiment
referring to accompanying drawing, a kind of demountor for dismantling the mining column end cap 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, be installed with tapered sleeve 4 and cutter fixed cover 5 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, be provided with baffle ring 20 between its leading section top and overcoat 3 inner rings, tapered sleeve 4 one ends are arranged in taper activity chamber, tapered sleeve 4 leading sections are by inserting bearing pin 14 and overcoat 3 secure fit in pilot hole, on tapered sleeve 4 and cutter fixed cover 5 inner rings, guide ring 11 is installed, 12, handle 6 also is installed on tapered sleeve 4, overcoat 3 is provided with handle 6 loose slots, also be provided with cutting jack driving bar 7 on overcoat 3, the other end of slide 1 is driven by work jack 8, 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 with 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 that cutter rotate, cutter assembly 2 overcoat 3 rearward end are provided with groove 18, and insert groove 18 with cutter assembly 2 and slide 1 fixed installation by plate 13, cutter are 16, are distributed on the front end face of cutter fixed cover 5, and its root and cutter fixed cover 5 be the integral type structure, and the cutter tooth of cutter is double-sided blade, handle 6 loose slots are helicla flute, cutting jack 10 is hydraulic jack, its piston rod external part and 7 fixed installations of cutting jack driving bar.
In Fig. 1, when work jack 8 is done extend action, promote dolly and be moved to the left.Be moved to the left by the cutter assembly 2 of two plate 13 pushing sleeves on the workpiece body of rod that is inserted in dolly square hole and cutter assembly 2 grooves dust-proof seal ring 15 places of approaching on workpiece.Start cutting jack 10 and do to stretch out, regain action, promote cutter assembly 2 and do clockwise, counterclockwise reciprocating rotary action.To make work jack 8 do the masterpiece that extend action produces less be the cutting centripetal force to the liquid back pressure of returning during cutting jack 10 action that formed by the utility model hydraulic system.The excision of realization to dust-proof seal ring 15 part rubber.Structure with cutter assembly 2 self is opened cutter tooth again, starts work jack 8 and does and regain action, and end cap 16 is pulled out from column 17.
In Fig. 2,3, cutter 19 are to make a groove and the cutter of root connection.Individual cutter tooth is all double-sided blade, does the anterior angle that is fit to the cutting elastomeric material.When overcoat 3 rotates, drive cutter by bearing pin 14 and rotate.The centripetal force that is formed by the machine makes cutter assembly 2 integral body 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 is crossed the inner face of end cap 16, move handle 6, due to the spiral fluted effect of opening on overcoat 3, handle 6 drives tapered sleeves 4 and is moved to the left.Because the bar of handle 6 is in the groove of cutter, cutter can not be done movement left.There are the male cone (strobilus masculinus) of tapered sleeve 4 and the effect of cutter inner conical surface that 16 cutters tooth of cutter are opened simultaneously.At this moment, the work jack 8 that starts the machine is done to regain action, and cutter assembly 2 is pulled out from column together with end cap 16.After end cap 16 breaks away from column, oppositely move handle 6, drive the relative cutter of tapered sleeve 4 and move right, make its male cone (strobilus masculinus) break away from cutter.Simultaneously drive again baffle ring 20 and move right, by the effect that another cone match is paid, 16 cutters tooth of cutter are retracted simultaneously, take off end cap 16.
In Fig. 4, be arranged on cutting jack 10 on dolly and do when stretching out, regaining action, drive the handle that has elongated slot on cutter assembly 2 and make cutter assembly 2 reciprocating rotaries.
