The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figures 1 to 4, the present invention includes first module body 1 and second unit body 2, by middle connecting plate 3, that both are affixed between first module body 1 and second unit body 2, make first module body 1 and second unit body 2 be connected to an integral body.First module body 1 and second unit body 2 comprise respectively two substrate 1-1 and substrate 2-1 separately, are arranged parallel to each other between each substrate, and substrate 1-1 and 2-1 are trapezoidal substrate; The symmetrical mounting blocks 5 of installing between the two substrates 1-1 of first module body 1, the installing hole that has fixture slippage passage and can supply locking latch to pass through in mounting blocks 5, sectional fixture 4 in fixture slippage passage, an end of fixture 4 connects the piston rod of clamping cylinder 6.As shown in Figure 3, Figure 4, at the affixed retaining mechanism in the bottom of mounting blocks 5.Described retaining mechanism comprises locking cylinder 13, locking latch 14 and installing plate 15, one end of locking cylinder 13 is installed on the bottom of mounting blocks 12, and the other end of locking cylinder 13 stretches out piston rod and is connected with installing plate 15, and locking latch 14 is installed respectively on the both sides in locking cylinder 13 on installing plate 15.As Fig. 1, shown in Figure 4, the structure of second unit body 2 is identical with the structure of first module body 1, inner flange 9 and outward flange 10 also are installed on the substrate 2-1 of second unit body 2, outward flange 10 is fixed in the outer wall of substrate 2-1, outward flange 10 supports mutually with the periphery of inner flange 9, and inner flange 9 is fixed on the outer wall of mounting blocks 5.One end of reverse arm 7 and a side of mounting blocks 5 are affixed, and the piston rod of the hinged torsion oil cylinder 8 of the other end of reverse arm 7 reverses the inwall that oil cylinder 8 is articulated in substrate 2-1.Go back sensor installation 12 on torsion oil cylinder 8, the telescopic displacement by sensor 12 test oil cylinders calculates windup-degree with this, has guaranteed machining accuracy.
Before reversing processing, the view of rail 11 before torsion as shown in Figure 5, after the rail 11 on roller-way rolls into the present invention, two groups of clamping cylinders, 6 work on first module body 1 and second unit body 2, clamping cylinder 6 task driven piston rods are stretched the cylinder motion, promote to move in the slippage passage of fixture 4 in mounting blocks 5 with this.Fixture 4 is clamped rail 11 after extending out to extreme position.Two groups of locking cylinders, 13 work this moment, the piston rod indentation of locking cylinder 13, drive installing plate 15 and be connected on the locking latch 14 of installing plate 15 and carry, until locking latch 14 stretches into the locking latch installing hole in mounting blocks 5, completing secondary fixes, prevent the loosening phenomenon that fixture occurs because twisting resistance is excessive, improve fastness and the reliability of clamping.
After fixture 4 clamps rail 11, because strain produces fine clearance, carry out the process of the torsion of the low moment of torsion of low pressure low speed this moment, as shown in Figure 4, a piston rod 8-1 who reverses oil cylinder stretches out, another reverses the piston rod 8-2 indentation of oil cylinder, the piston rod that reverses oil cylinder 8 stretches out and indentation drives the swing of reverse arm 7, because an end and the mounting blocks 5 of reverse arm 7 are affixed, and affixed inner flange 9 on the outer wall of mounting blocks 5, so the swing of reverse arm 7 finally drives mounting blocks 5 and inner flange 9 slightly rotates.In twist process, the linear drives power of reversing oil cylinder 8 generations is converted into the rotation torque of reverse arm 7, piston rod promotion fixture 4 by clamping cylinder 6 is delivered to the low moment of torsion of low pressure low speed that produces on the rail 11 that is held, rail 11 reverses owing to producing under the torsional moment that is provided by reverse arm 7, the low moment of torsion that reverses of this low pressure low speed can not produce moulding distortion to rail, only needs the fine clearance that produces because of strain except between fixture and rail.
After carrying out the torsion of the low moment of torsion of low pressure low speed, the gap of having eliminated 4 of rail 11 and fixtures.After reaching the setting moment of torsion, start sensor 12 detects and measures windup-degree.Carry out the high moment of torsion of high-voltage high-speed this moment and reverse, its operation principle is equal to the low moment of torsion of low pressure low speed and reverses.Rail 11 is produced under the effect of the high moment of torsion of high-voltage high-speed reverse moulding distortion, when reversing to required angle and springback capacity, stop the present invention to the torsion of rail after recording by sensor 12, guaranteed the torsion precision.After stopping the several seconds, changing the low moment of torsion of low pressure low speed into reverses in the other direction, eliminate the springback capacity of rail 11 with this, and draw the final angle value by sensor 12 detections, calculate the actual angle value, and by display unit, angle value is shown (this display unit is not shown), realized the controllability of Rail torsion angle.If do not meet with the set angle value, also can carry out the bidirectional torsion correction, realized the accurate sizing of windup-degree.
Fig. 6 is the view after Rail torsion, and its windup-degree is 6.8 ° (according to the difference of steel-rail rail-road switch model, its windup-degree is not identical).
After torsion machines, locking cylinder 8 work, each is organized locking latch 14 releasings the secondary of fixture 4 is fixed, clamping cylinder 6 work, the piston rod of clamping cylinder 6 is retracted, and drives fixture 4 and unclamps rail 11, and the roller-way upset makes rail 11 shift out the present invention.
Above description is explanation of the invention, is not that limited range of the present invention is referring to claim, in the situation that without prejudice to basic structure of the present invention, the present invention can do any type of modification to the restriction of invention.
