The specific embodiment
During work, trachea material feeder is under the effect of lift cylinder 18, trachea material feeder is lifted, the conduit process vibrating bunker vibrating ordering that need be pressed into is after flexible pipe is delivered to pipe joint 13 places of this device, and enter in the locating hole of A feeding slide plate 11, under the effect of pusher cylinder 10, promote 11 feedings forward of A feeding slide plate, conduit is delivered to the position.When insert the Kong Zhonghou that is pressed conduit with flexible depression bar 29 (in left and right sides conduit, the seat ring press-loading apparatus 5), pay-off is under the effect of lift cylinder 18, and decline resets, and pusher cylinder 10 drives A feeding slide plate 11 and sets back.
During work, deliver to the charging aperture place of this device U-lag plate B behind the seat ring process vibrating bunker vibrating ordering that need press-fit, B feeding slide plate 20 is under the effect of feeding cylinder 19, send to forward, the seat ring that needs press-fit is delivered to the position, at this moment clamp seat ring by a pair of slip blade 22 under the effect of spring, feeding cylinder 19 is being with B feeding slide plate 20 to set back, when the push rod 30 in the left and right sides seat ring press-loading apparatus 5 rises under the effect of following oil cylinder 31, be with seat ring to head in the cylinder head.
Contrast accompanying drawing 7, its structure is that upper cylinder 24 is fixed in the above on the plate 25, top panel 25 is fixed on the B guide pillar 26, B guide pillar 26 is fixed on the base 9, pressure head 28 is fixed on the pressing plate 27, depression bar 29 is fixed in the pressure head 28, and upper cylinder 24 moves up and down by laced belt dynamic pressure plate 27, also just is being with depression bar 29 to get conduit and is pressed into conduit.Following oil cylinder 31 is fixed on the base 9, and push rod 30 is connected with following oil cylinder 31 by joint, and base 9 is fixed on the lathe bed 3 by screw, under the action of following oil cylinder 31, drive push rod 30 and pass the required seat ring that is pressed into, following oil cylinder 31 continues up, and seat ring is pressed in the cylinder head.
Left and right sides compressing fixture fixedly cylinder head part is used, it is by a plane and two alignment pin (straight pins, a rhombus pin), the cylinder head part is positioned on the compressing fixture, by a swinging oil cylinder and a lever oil cylinder workpiece pressing, left and right sides compressing fixture is separately fixed on the base 9.
Whole lathe protection is the protecting component that is fixed on the lathe bed, in the work of press-fiting, manually cylinder head is put into pressing clamp, closes the lathe protective door, starts the lathe button, and the work that press-fits is finished automatically.
Left and right sides conduit, seat ring vibrating bunker 7 are put into the conduit and the seat ring part that need press-fit respectively, through the vibrating ordering of vibrating bunker, through flexible pipe conduit are sent into trachea material feeder, through raceway seat ring are sent into the seat ring pay-off.
Left and right sides hopper base 6 is basic parts of placing vibrating bunker 7.
Press-fit the work of special plane:
At first the finished parts of valve guide bushing that needs are press-fited and valve retainer is put into the vibrating bunker of conduit, seat ring respectively, the left side is put valve guide bushing and inlet valve seat ring into, right side rafting valve guide bushing and exhaust valve seat insert, through the vibration and the ordering of vibrating bunker, conduit and seat ring are sent into respectively in the pay-off of conduit and seat ring; The cylinder head part is put into compressing fixture, by a plane and two alignment pins (straight pin, a rhombus pin) location, hydraulic jack workpiece pressing.Pay-off is under the effect of lift cylinder, pay-off is lifted, pipe joint on the device links to each other with the conduit vibrating bunker by flexible pipe, conduit process vibrating bunker vibrating ordering is after flexible pipe is delivered to pipe joint place of this device, and enter in the locating hole of feeding slide plate, under the effect of feeding cylinder, promote the feeding forward of feeding slide plate, conduit is delivered to the position.The conduit press-loading apparatus is descending under the effect of upper cylinder 24, and the depression bar 29 that is contained in the pressure head inserts in the conduit, and it is descending to be with conduit to continue, and conduit is pressed in the cylinder head; Deliver to the charging aperture place of pay-off U-lag plate behind the seat ring process vibrating bunker vibrating ordering that need press-fit, the feeding slide plate is under the effect of feeding cylinder, send to forward, the seat ring that needs press-fit is delivered to the position, at this moment under the effect of spring, clamp seat ring by a pair of slip blade, under the action of the following oil cylinder 31 in the seat ring press-loading apparatus, drive push rod 30 and pass the required seat ring that is pressed into, following oil cylinder 31 continues up, seat ring is pressed in the cylinder head, upper cylinder 24 and following oil cylinder 31 move simultaneously, finish the work that press-fits of conduit and seat ring.
Be pressed into the control of position:
The position that is pressed into of conduit is to control by the axial distance of pressure head 28 and depression bar 29, in when design, the axial dimension of pressure head 28 and depression bar 29 is controlled at ± the 0.03mm scope in.The size that is pressed into of seat ring is to guarantee by the stroke of controlling down oil cylinder 31 near switch.
The size of inlet valve conduit, seat ring and exhaust valve guide, seat ring and size are different, thereby are pressed into inlet valve and exhaust valve guide, the push rod of seat ring and the size and the size of depression bar also are different.
The control of feeding position:
The control of feeding position is very important in self-feeding, requires the required conduit that is pressed into to deliver to the below of depression bar 29 in the press-loading apparatus 5, and and depression bar 29 coaxial lines, require the required seat ring that is pressed into to deliver to the top of push rod 30, and and push rod 30 coaxial lines.Could guarantee that like this depression bar 29 continues be with conduit to be pressed in the cylinder head guide hole when descending, when push rod 30 is up, be with seat ring to head in the cylinder head seat ring hole.
The control of trachea material feeder lifting position is to control by the position of regulating spacing Hough 16, the position that require to guarantee the conduit that send in the conduit press-loading apparatus depression bar 29 below, when guaranteeing that depression bar 29 descends, insert by in the hole of pressure conduit detail.The status requirement of conduit feeding is consistent with the center of depression bar 29 in the conduit press-loading apparatus.The control of this position be touch baffle plate on the U-lag plate by the limited block on the feeding slide plate 14 till.
The seat ring pay-off is installed in the below of cylinder head part, the top of press-loading apparatus push rod 30 and push rod 30 coaxial lines, and this requirement is by when assembling, adjusts that the position of seat ring pay-off reaches.
Conduit, seat ring enter depression bar and push rod can not run-off the straight, the control of rollover:
The required conduit that is pressed into requires not run-off the straight when entering depression bar 29, otherwise just conduit can not be pressed in the cylinder head, in design for head it off, specially in conduit feeding slide plate, made a cylindrical hole, and it is suitable to make aperture and institute press-fit the conduit gap, conduit is fixed in the hole, when depression bar 29 is descending, inserts conduit, and not run-off the straight.
The required seat ring that is pressed into requires seat ring not turn on one's side when push rod 30 enters, otherwise push rod 30 just can not enter in the seat ring hole, press-fits and can't carry out.For head it off, in the seat ring pay-off, adopt one group of slip blade 22 under the effect of spring, to help the seat ring of firmly delivering to the position, when push rod 30 is up, strutted slip blade 22, push rod 30 just can enter in the seat ring hole smoothly, has guaranteed the carrying out that press-fits.
