Fig. 2 is the structural representation of the utility model V-type bearing;
Fig. 3 is the utility model piston scheme of installation;
1. bases among the figure, 2. upper box, 3.V type bearing, 4. oil cylinder, 5. oil cylinder piston bar; 6. vane pump is 7. increased backing plate, 8. pressure head, 9. shaft coupling, 10. motor; 11. storage disks, 12. rubber slabs, 13. piston rods, 14. piston pins, 15. pistons; 31. base plate, 32. panels, 33. copper packings, 34.V type piece, 35. slide plates.
The specific embodiment
This diesel engine piston pin provision for disengagement comprises base 1, upper box 2, V-type bearing 3, oil cylinder 4, oil cylinder piston bar 5, vane pump 6, increases backing plate 7, pressure head 8, shaft coupling 9, motor 10, storage disks 11, rubber slab 13, base plate 31, panel 32, copper packing 33, V-block 34 and slide plate 35.
Like Fig. 1 is the structural representation of the utility model, and base 1 one sides are provided with upper box 2, and opposite side is provided with V-type bearing 3; Be provided with oil cylinder 4 in the upper box 2, oil cylinder 4 is connected with oil cylinder piston bar 5, is provided with vane pump 6 in the base 1; Base 1 has two and increases backing plate 7, and oil cylinder piston bar 5 one sides are provided with pressure head 8, and vane pump 6 is connected with motor 10 through shaft coupling 9; V-type bearing 3 is by base plate 31, panel 32, copper packing 33, V-block 34 and slide plate 35, and base plate 31 is fixedly connected with panel 32, and panel 32 is fixedly connected with V-block 34; Copper packing 33 is fixedly connected with V-block 34, and V-block 34 1 sides are provided with slide plate 35, and slide plate 35 is connected with storage disks 11; Storage disks 11 inner bottom parts are provided with rubber slab 12 around reaching, and can accomplish the dismantlement work of piston pin easily, and guarantee the dismounting quality of piston pin.
Like Fig. 2 is the structural representation of the utility model V-type bearing; V-type bearing 3 is made up of base plate 31, panel 32, copper packing 33, V-block 34 and slide plate 35; Base plate 31 is fixedly connected with panel 32, and panel 32 is fixedly connected with V-block 34, and copper packing 33 is fixedly connected with V-block 34; V-block 34 1 sides are provided with slide plate 35, make piston to be well fixed.
During use, as shown in Figure 3, piston rod 13 handlings that at first will dismantle are to V-type bearing 3; After steadily placed the location, starter motor 10 drove vane pump 6 work by shaft coupling 9; Then the oil cylinder piston bar 5 of operating cyloinder 4 advances or retreats, and piston pin 14 is slowly ejected for 15 li from piston, and be slipped in the storage disks 9 on the base through slide plate 35; Storage disks 9 inwalls and bottom are used to cushion and protect the surface of piston pin to avoid collision with rubber slab 10, piston 15, piston rod 13 are hung out from base 1 to get final product at last; So just, accomplished the dismantlement work of piston pin; Because the axis in the axis of oil cylinder piston bar 5 and V-type bearing 3 holes has the assurance of axiality, and the requirement of the depth of parallelism, flatness is arranged, thereby the dismounting quality of piston pin can be fully protected with base plane.Simultaneously, for preventing the termination fail in compression of oil cylinder piston bar 5, oil cylinder piston bar 5 one sides are provided with disconnectable pressure head 8; Improved the service life of oil cylinder piston bar greatly; Guarantee that piston pin is evenly stressed in when dismounting, base 1 have two increase 7, two on backing plate increase backing plate 7 be positioned at oil cylinder piston bar 5 under; Be convenient to adjust the piston pin hole center line and oil cylinder piston bar center line remains on sustained height, can satisfy the dismounting of the piston rod group of different size, model.The provision for disengagement of this diesel engine piston pin is simple in structure, and is easy to use, practical, and security and reliability are relatively good, and result of use is good, has improved operating efficiency, has reduced labour intensity, is easy to apply.
