As shown in Figure 1, all oil cylinders of hydraulic system of the present invention are all controlled work or reset by reversal valve 5, and sequence valve 3 controls to allow after four thin-walled oil cylinders 7 first work the second clamping cylinder and the first clamping cylinder work again.3-position 4-way selected by the reversal valve 5 of the present embodiment, and it is communicated with four thin-walled oil cylinders 7 respectively, and reversal valve 5 is also communicated with sequence valve 3 simultaneously, and the counterclockwise oil cylinder of counterclockwise two-way cylinder 4,17, clockwise oil cylinder 21 is communicated with this sequence valve 3 with three again.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, when the present invention uses, be placed on respectively by four connecting rods 20 on four stations on jig plate 2, connecting rod 20 is put rear large stomidium and is directly located by the rhombus pin 14 in its second through hole 160, and little stomidium is then enclosed within corresponding boss 80.Connecting rod 20 puts rear reversal valve 5 well to four thin-walled oil cylinder 7 fuel feeding, four piston rods are all moved up, the each conehead bar 10 be in transmission connection with it is moved up along the first corresponding through hole 81, the inclined-plane of the conehead of conehead bar 10 continues to move up after encountering the inclined-plane ejecting post 12, the inclined-plane of conehead bar 10 is squeezed eject the inclined-plane of post 12, the wall of the little stomidium of ejection post 12 to connecting rod 20 in cross through hole 800 is removed, and the final post 12 that ejects is against on the wall of little stomidium.Simultaneously isolating pad 13 is blocked spring 11 and is prevented from it to be extruded ejecting post 12 pairs of connecting rods 20 causing damage.Squeezing the inwall of little stomidium because ejecting post 12, the little stomidium of connecting rod 20 being restricted in the movement of boss 80 surrounding, achieving location.The present invention also can arrange two, three cross through hole 800, establishes an ejection post 12 in each cross through hole 800 respectively, so can be located by the wall of little stomidium from multiple directions, connecting rod 20 be located more stable.After connecting rod 20 location, sequence valve 3 is connected with reversal valve 5, makes reversal valve 5 respectively to counterclockwise oil cylinder 17, clockwise oil cylinder 21 and three counterclockwise two-way cylinder 4 fuel feeding.When counterclockwise oil cylinder 17 is worked by fuel feeding back piston bar, rotate counterclockwise while the single head pressing plate 18 be in transmission connection with it is raised, decline after turning an angle, be finally pressed in the large stomidium side of the connecting rod 20 near it, thus achieve the compression operation of large stomidium.When clockwise oil cylinder 21 is worked by fuel feeding back piston bar, rotate clockwise while the single head pressing plate 18 be in transmission connection with it is raised, when degree of turning an angle declines, be finally pressed in the large stomidium side of the connecting rod 20 near it, thus achieve the compression operation of large stomidium.The connecting rod 20 of jig plate 2 both sides compresses by above-mentioned two single head pressing plates 18.After three counterclockwise two-way cylinders 4 are by fuel feeding, three piston rods all work, rotate counterclockwise while three double-head pressing plates 19 be in transmission connection with three piston rods are raised, decline after turning an angle, the double-head pressing plate 19 of final both sides by the little stomidium side compression of adjacent two connecting rods 20, by the large stomidium side compression of adjacent two connecting rods 20 after middle double-head pressing plate 19 rotates.Two single head pressing plates 18 and three double-head pressing plates 19 make the large stomidium side of each connecting rod 20 and little stomidium side all compacted, thus achieve the reliable object compressing connecting rod 20.
After four connecting rod 20 positioning compressions, inclined-plane cutting is carried out to the little stomidium of each connecting rod 20.After cutting, reversal valve 5 and sequence valve 3 are first connected, and counterclockwise oil cylinder 17, clockwise oil cylinder 21 and three counterclockwise two-way cylinders 4 are by after fuel feeding; Rotate clockwise while three double-head pressing plates 19 raise, compacted connecting rod 20 is unclamped; The single head pressing plate 18 of both sides goes back to origin-location, is unclamped by compressed connecting rod 20; Then reversal valve 5 and sequence valve 3 disconnect, move down to four its piston rods of thin-walled oil cylinder 7 fuel feeding, conehead bar 10 is moved down, the inclined-plane of the conehead of conehead bar 10 is separated with the inclined-plane ejecting post 12, ejection post 12 is well resetted under the effect of spring 11, makes the little stomidium of connecting rod 20 lose the power of location.Now direct connecting rod 20 to be taken off, carry out next operation.
Due to connecting rod 20 of the present invention location clamping and unclamp, be all automatically controlled to carry out by hydraulic jack, thus location is clamped and the speed of unclamping fast, and location clamping is precisely stable.Therefore present invention saves the time of positioning linkage rod 20, improve production efficiency, save the amount of labour, what also make connecting rod 20 inclined-plane cut is more accurate.
The present invention can arrange the station of processing connecting rod 20 is in addition one, two, three, five and six etc., and the quantity of corresponding double-head pressing plate 19 is zero, one, two, four and five etc.
The above preferred embodiment of the present invention; and not in order to limit the present invention; all any amendments done within the spirit and principles in the present invention, etc. the hydraulic clamp positioner and improvement etc. on same Machining of Connecting Rod inclined-plane, all should be included within protection scope of the present invention.
