Abstract
The utility model discloses an engine valve seat ring detacher, which relates to devices for detaching metal components and comprises a pressing plate (4), a pull rod (7), a spherical washer (2), a conical washer (3), a nut (1), an elastic sleeve (6) and a stop pin (5). The pressing plate (4) is a cylinder with an open bottom end, the center of the top end of the pressing plate (4) is provided with a hole, and the lateral surface of the pressing plate (4) is provided with an observation hole (8). The pull rod (7) penetrates through the central hole of the pressing plate (4), the top end of the pull rod (7) is provided with a hexagonal head (9), the upper end of the pull rod (7) is provided with threads, and the lower end of the pull rod (7) is sleeved with the elastic sleeve (6). The elastic sleeve (6) is fixed on the pressing plate (4) by the aid of the stop pin (5), the nut (1) is sleeved at the upper end of the pull rod (7) in a threaded mode, and the spherical washer (2) and the conical washer (3) are mounted between the nut (1) and the pressing plate (4) sequentially. The engine valve seat ring detacher has the advantages of convenience in use, working hour economization and no damage to a cylinder valve seat ring mounting hole, and can be used for detaching valve seat rings with internal bore diameters ranging from 20mm to 50mm.
Description
Technical field
The utility model relates to the device of taking metal parts apart, specifically, relates to the engine valve retainer provision for disengagement.
Background technology
The dismounting of engine valve retainer, manual method are to destroy the back with chisel to remove, and obviously this is extremely original method, both damaged the seat ring installing hole easily, and work efficiency is extremely low.Therefore people have developed many extracting tools, the application part that relates to the engine valve retainer dismounting in Chinese patent literature is a lot, for example No. 91226155.2 " engine cylinder cover valve retainer puller ", number 93203042.4 " slide block type valve retainer stripping attachment ", number 93218963.6 " not having (bearing) inward flange formula valve retainer puller ", number 96225776.1 " valve retainer is extracted machine ", number 99233889.1 " valve seating race pulling device ", number 200320114329.8 " circular cone screw tap shape valve seating race pulling device ", number 200820104472.1 " engine valve retainer provision for disengagement " etc., these patented technologies all have and change the effect of hand disassembly for machinery dismounting, but people continue to explore the instrument that design can solve the time-consuming problem of unloading process.
Summary of the invention
The purpose of this utility model is to provide a kind of engine valve retainer stripping attachment, can realize the fast quick-detach to a plurality of specification valve retainers, reduces work hours, and does not decrease the valve retainer installing hole.
The engine valve retainer stripping attachment that the designer provides is made up of pressing plate, pull bar, spheric washer, taper faced washer, nut, resilient sleeve, latch, and pressing plate is the cylinder of bottom end opening, and its center, top is porose, and there is peep hole the side; Pull bar passes the pressing plate centre bore, and there is turret head on its top, and there is screw thread the upper end, and the lower end is with resilient sleeve, and resilient sleeve is fixed on the pressing plate by latch; Pull bar upper end screw thread is with nut, and spheric washer and taper faced washer are housed between nut and the pressing plate successively.
The diameter of above-mentioned pull bar lower end is greater than the upper end.
There is the hole with the pressing plate coupling at above-mentioned spheric washer and taper faced washer center, are enclosed within on the pressing plate during use.
Stripping attachment has 1～5 kind of specification that varies in size, and is used to dismantle the valve retainer of different-diameter.
The using method of engine valve retainer stripping attachment is: the rotating rod turret head, make nut rise to the top, upper end, firmly push pull bar, make the lower end enter the below of valve retainer and make resilient sleeve catch on the periphery of seat ring bottom, the rotating rod turret head is to tighten up resilient sleeve afterwards, rotate nut with spanner again, rely on the power pulling seat ring between the screw thread, up to valve retainer is all pulled out.
Engine valve retainer stripping attachment of the present utility model, have easy to use, save man-hour, do not damage the advantage of cylinder valve retainer installing hole, can be used for dismantling the valve retainer that the seat ring diameter of bore is 20～50mm.
Description of drawings
Fig. 1 is the structural representation of engine valve retainer stripping attachment of the present utility model, and 1 is nut among the figure, and 2 is spheric washer, and 3 is taper faced washer, 4 is pressing plate, and 5 is latch, and 6 is resilient sleeve, and 7 is pull bar, 8 is peep hole, and 9 is turret head, and 10 is valve retainer, and 11 is cylinder cover.
The specific embodiment
Embodiment: as the engine valve retainer stripping attachment of accompanying drawing, be used to dismantle the valve retainer 10 of the diameter of bore 20mm on the cylinder cover 11, it is made up of pressing plate 4, pull bar 7, spheric washer 2, taper faced washer 3, nut 1, resilient sleeve 6, latch 5, pressing plate 4 is the cylinder of bottom end opening, its center, top is porose, and there is peep hole 8 side; Pull bar 7 passes pressing plate 4 centre bores, and there is turret head 9 on its top, and there is screw thread the upper end, and the lower end is with resilient sleeve 6, and resilient sleeve 6 is fixed on the pressing plate 4 by latch 5; The screw thread of pull bar 7 upper ends is with nut 1, and spheric washer 2 and taper faced washer 3 are housed between nut 1 and the pressing plate 4 successively.
The diameter of pressing plate 4 cylinders is 76mm, highly is 55mm, and center-hole diameter is 25mm, and the length of pull bar 7 is 130mm, and the upper end diameter of thread is 20mm, and the lower end diameter of thread is 24mm.
