The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
Like Fig. 1, Fig. 4 and shown in Figure 5; The utility model is a kind of automatic hoisting mechanism of flange ring milling train core roller, comprises that base 2, connecting axle 3, up-down cylindrical shell 5, up-down beam 6, core roller 1, lift cylinder 4, guide cylinder 9, rolling bearing 11, core roller locking cylinder 18, core roller move cylinder 22, master cylinder 19 and displacement transducer 20.One end of lift cylinder 4 is fixed on the base 2, and the other end is connected with up-down beam 6 through bearing pin 8.Up-down beam 6 connects as one through connecting bolt 7 and up-down cylindrical shell 5, core roller 1.Up-down cylindrical shell 5 is slidingly connected with guide cylinder 9.Core roller 1 is fixing with connecting axle 3 through trip bolt 10.Rolling bearing 11 is in the connecting axle 3, be arranged on core roller 1 around.Displacement transducer 20 is housed on the lift cylinder 4, and displacement transducer 20 is connected with the controller of flange ring milling train.Mandrel moves cylinder 22 and 1 vertical connection of core roller.Core roller locking cylinder 18 moves 22 vertical connections of cylinder with mandrel.
As shown in Figure 2, lift cylinder 4 comprises flange 12, cylinder head 13, piston rod 14, cylinder body 15, sealing ring 16 and piston 17.Flange 12 is fixed on cylinder head 13 in the cylinder body 15.Piston rod 14, sealing ring 16 is in the cylinder body 15 with piston 17.The end that piston 17 is in cylinder body 15 openings is connected through sealing ring 16 with piston rod 14.
As shown in Figure 3; When the plunger shaft of Compressed Gas P through the check valve passage entering lift cylinder of NG30 adjustable pressure-reducing valve, NG22 3-position 4-way solenoid directional control valve, NG22 air pressure lock, NG22 one-way throttle valve; Promote piston, piston rod is up; Drive core roller lowering or hoisting gear and mention, reach the purpose that the core roller goes up and down; The Compressed Gas of rod end chamber flows back to air-pressure duct T through throttling passage, the 3-position 4-way solenoid directional control valve of NG22 one-way throttle valve.
Like Fig. 4 and shown in Figure 5, because the core roller automatic lifting that will realize,, symmetrical two lift cylinders 4 must be set for core roller 1 is risen and fallen stably so what at first will gather is lift cylinder 4 and the position in the elevating mechanism.Therefore on flange ring milling train single-chip microcomputer programmable controller, increase counting module, increase the up-down control program, increased encoder collection position data and relevant auxiliary equipment.
Displacement transducer 20 is installed on the lift cylinder 4, is connected on the high speed counting module in the single-chip microcomputer in the electric box through shielding line.
Compressed Gas gets in the cylinder body 15 from the cylinder head 13 of lift cylinder 4; Promote piston 17; Piston 17 drives piston rod 14 and in lift cylinder 4, moves vertically upward, and piston rod 14 connects up-down beam 6 through bearing pin 8, under the control of electric control system; Two lift cylinders 4 are mentioned core roller 1 device along guide cylinder 9 automatically rapidly, put into and take out for blank and shaping ring and leave sufficient space.After blank is put into workbench; Under the control of electric control system; Lift cylinder 4 air inlets promote piston 17 and drive piston rod 13, and it is descending along guide cylinder 9 that pulling up-down beam 6 drives the core roller arrangement; And 1 in core pierced in the blank hole, tightly pin mandrel 10 through mandrel locking cylinder 18 simultaneously and move cylinder 22 through mandrel and drive whole lowering or hoisting gear along continuous straight runs and move.Through the work of master cylinder 19, make the ring blank carry out radial rolling simultaneously at king roller 21 and 1 of mandrel.For mandrel is rotated easily, fastening bolt 10 is integrated 3 of core roller 1 and connecting axles, and rolling bearing 11 is installed above that.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
