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.
As Fig. 1 is structural representation of the present invention, base 1 one sides are provided with upper box 2, 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, be provided with vane pump 6 in the base 1, base 1 has two and increases backing plate 7, oil cylinder piston bar 5 one sides are provided with pressure head 8, and vane pump 6 is connected with motor 10 by shaft coupling 9, and V-type bearing 3 is by base plate 31, panel 32, copper packing 33, V-block 34 and slide plate 35, base plate 31 is fixedlyed connected with panel 32, panel 32 is fixedlyed connected with V-block 34, and copper packing 33 is fixedlyed connected with V-block 34, and V-block 34 1 sides are provided with slide plate 35, 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 finish the dismantlement work of piston pin easily, and guarantee the dismounting quality of piston pin.
As Fig. 2 is the structural representation of V-type bearing of the present invention, V-type bearing 3 is by base plate 31, panel 32, copper packing 33, V-block 34 and slide plate 35, base plate 31 is fixedlyed connected with panel 32, panel 32 is fixedlyed connected with V-block 34, copper packing 33 is fixedlyed 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 place the location; starter motor 10; drive vane pump 6 work by shaft coupling 9; then the oil cylinder piston bar 5 of operating cyloinder 4 advances or retreats; 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, at last with piston 15 with rubber slab 10; piston rod 13 hangs out from base 1 and gets final product; so just, finished the dismantlement work of piston pin; because the axis of oil cylinder piston bar 5 and the axis in V-type bearing 3 holes have the assurance of axiality, and the depth of parallelism is arranged with base plane; the requirement of flatness, thereby the dismounting quality of piston pin can be fully protected.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.
