Abstract
A special tool capable of pulling out an engine cylinder cover valve seat ring.
The structure and the principle of the device are as follows: the atraumatic positioning sleeve 10 is connected to the lifting bolt 1 by means of a screw 11. The lifting claw 6 is connected with a lifting nut 9 by a pin 8. The three lifting claws are held tightly by a spring 7 to reset. When in use, the injury-proof locating sleeve is inserted into the valve guide pipe of the cylinder cover 12. The three lifting claw tips are adjusted to be slightly lower than the valve seat ring 5, the hexagonal nut 2 is screwed downwards, the axial force is decomposed into radial force through the conical pressure plate 4, the radial force is pressed towards the lifting claws, and the lifting claw tips are pressed into the hole wall below the valve seat ring. The lifting bolt is tightened to move the lifting nut 9 upwards as a whole, and the seat ring is taken out.
Description
The utility model is a kind of special-purpose series of tools of the various engine cylinder cover intake and exhaust seat rings of choosing.Be characterized in guaranteeing product quality, the rate of reducing the number of rejects and seconds, and can make old to upgrade use.
The processing of head valve seat ring and valve guide hole is last one critical process of cylinder cap.Valve guide hole with respect to the axiality of valve retainer band overproof cause useless; The valve retainer sealing has ripple and scuffing can cause useless; Also can cause useless because of scarce operation processing press-fits seat ring.
Because the diameter of bore that press-fits on the endoporus of valve retainer and the cylinder cap below the valve retainer bottom outlet is basic identical, so the seat ring of choosing is very difficult.Can only prize, beat from several aspects with screwdriver, efficient be very low.Take off reluctantly, the faying face of seat ring bottom outlet is destroyed.Because seat ring is not vertically chosen, so the distortion of seat ring bottom outlet is serious, be extruded into ellipse again, diameter also becomes greatly, though seat ring is removed, cylinder cap is scrapped.Domestic each producer as far as I know generally is to scrap processing to the settling mode of the problems referred to above.
The purpose of this utility model provides a kind of specific purpose tool of the engine cylinder cover inlet and exhaust valve seat ring of choosing, and makes to scrap cylinder cap and can reprocess after press-fiting the neostigma seat ring.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is a vertical view of the present utility model.
Fig. 2 is the utility model is done structure, principle explanation along the A-A direction a revolved section schematic diagram.
With bolt 11 the anti-positioning sleeve 10 of hindering is connected connection with elevator bolt. Are connected connection with bearing pin 8 with hoisting nut promoting pawls 6. Three lifting pawls are held tightly by spring 7 and are resetted. During use, will prevent hindering positioning sleeve and insert in cylinder cap 12 valve guide holes. Three pawl points that promote pawls are transferred a little less than the position below the valve retainer 5, be screwed down six square nuts 2, downward axial force is decomposed into radial load by taper platen 4, presses and go to promoting pawl, make to promote the pawl point and be pressed in the cast iron and proceed to seat ring below 0.2mm-0.3mm. Screw elevator bolt, the hoisting nut that will become one, lifting pawl, taper platen, six square nuts and valve retainer upwards axially move, the distance of a mobile seat ring thickness, and seat ring just is removed. All Time only needed for 20 seconds.
The utility model used through 1 year four months, and effect is fine.
Adopt advantage of the present utility model: (1) can make waste product not useless, reduces product cost; (2) the seat ring bottom diameter after choosing is within the margin of tolerance; (3) Zai Jiagong cylinder cap, measuring guide internal diameter and guide hole counter race valve band axiality are all not overproof; (4) simple and compact for structure, volume is little, and cost is low; (5) easy to use, pickup is rapid.
Claims (1)
1, a kind of engine cylinder cover valve retainer puller is characterized in that: be connected with elevator bolt 1 preventing hindering positioning sleeve 10 with bolt 11, be connected with hoisting nut 9 promoting pawl 6 with bearing pin 8, three promote pawl and hold 1 again tightly by spring 7.
