Abstract
The invention discloses an appliance special for dismounting a valve seat ring of a diesel engine cylinder cover. The appliance is characterized in that a locating nut is arranged on a locating screw and a lead screw lifting screw is provided with a lifting nut and a support in a sheathed mode. A conical surface expanding and locating plate is arranged below the lifting nut, the lower end face of the locating plate is in threaded connection with a locating shaft, the lower end of the lifting nut is provided with three valve seat ring grapple hooks at the interval of 120 degrees, each valve seat ring grapple hook is connected with a sleeve wall at the lower end of the lifting nut by virtue of a shaft, and the grapple hook can be spread or closed. A lifting mechanism which is composed of a guide device, a conical surface jacking device and three valve seat ring grapple hooks connected with a screw bush into a whole is adopted to take out a valve seat ring while being lifted upwards. In the invention, the lead screw lever principle is utilized to conveniently dismount the valve seat ring pressed on a cylinder cover in interference fit, a bearing at a flywheel end of engines in different models can be taken out, the bearing and the valve seat ring can not be damaged in the dismounting process, and the appliance has the characteristics of being simple in structure and being convenient and fast.
Description
Technical field
The invention belongs to the internal combustion engine component extracting tool, be specifically related to a kind of utensil that is exclusively used in dismounting diesel engine spiracle seat ring.
Background technology
The diesel engine spiracle seat ring is the vitals on the cylinder cap, and valve retainer is fitted on the cylinder cap with interference fit in assembling process, therefore in maintenance or the very difficult dismounting of valve retainer in the cylinder cap air flue test.The employed instrument of dismounting valve retainer all is to press dismounting, result to be easy to cause valve retainer to damage with sleds such as some spanners commonly used, screwdriver, pliers at present, also might damage critical components such as cylinder cap plane and air flue valve guide bushing simultaneously.If can propose a kind of special implement of easy, nondestructive demounting valve retainer, then be that the institute of the industry asks, and the present invention proposes for solving this difficult problem.
Summary of the invention
The purpose of this invention is to provide a kind of rational in infrastructure, head valve seat ring extracting tool easily.
Below in conjunction with the drawings structural principle of the present invention is described.Diesel engine cylinder cover valve retainer dismounting special implement has: positioning screw, setscrew nut, leading screw lift-bolt cover, hoisting nut, valve retainer grapple and conical surface expansion positioning disk, support etc.The present invention utilizes the design of leading screw lever principle: the dismounting special implement is divided into three parts, first is guide locating device provided, the locating shaft front end of the conical surface being expanded positioning disk lower end (by being threaded) inserts in the valve guide bushing of cylinder cap, play the guide-localization effect, drive on the awl conical surface expansion positioning disk mobile by the setscrew nut that turns clockwise, can be with the grapple jack-up of dismounting valve retainer, with the firm valve retainer bottom, hook jail of grapple; Second portion is the valve retainer extracting apparatus, and 3 uniform grapples and leading screw lift-bolt cover are linked as one; Third part is the part of dismounting valve retainer most critical, at first be that the firm frame of the support of circular ring surface is on the cylinder cap baseplane, valve retainer is covered fully, because 3 grapples are hook jail valve retainer bottom, setscrew nut fastens the positioning screw positional lock, this moment, hoisting nut was the strong point of power with the support upper surface, clockwise rotated by hoisting nut, and drive leading screw lift-bolt puts to move and utilizes 3 grapples that valve retainer is extracted.The technical scheme that its parts connect is: positioning screw, setscrew nut, leading screw lift-bolt cover and hoisting nut are screw connection structure each other, below hoisting nut, be provided with conical surface expansion positioning disk, the conical surface expansion center of circle, positioning disk lower surface is by the locating shaft that has been threaded, and locating shaft and positioning screw are same axis.The interval, lower end of hoisting nut is provided with three valve retainer grapples for 120 °, and each valve retainer grapple is connected for axle with the sleeve wall of hoisting nut lower end, and the valve retainer grapple can strut or be closed.
Description of drawings
Shown in accompanying drawing be the technology of the present invention principle and structure diagram.
The specific embodiment
Be described further below in conjunction with accompanying drawing and to structural principle of the present invention.As shown in the figure, diesel engine cylinder cover valve retainer dismounting special implement, its frame for movement is: positioning screw 1 is precession setscrew nut 2, leading screw lift-bolt cover 3, hoisting nut 4 and support 5 successively, and positioning screw 1, setscrew nut 2, leading screw lift-bolt cover 3 and hoisting nut 4 are screw connection structure each other.Be provided with conical surface expansion positioning disk 7 below hoisting nut 4, the conical surface expansion center of circle, positioning disk lower surface is by the locating shaft 8 that has been threaded, and locating shaft and positioning screw are same axis.The interval, lower end of hoisting nut 4 is provided with three valve retainer grapples 6 for 120 °, and each valve retainer grapple 6 is connected for axle with the sleeve wall of hoisting nut 4 lower ends, and the valve retainer grapple can strut or be closed.The hoisting nut 4 that is positioned at support 5 upper surfaces is hexagonal structure, and being positioned at support 5 upper surfaces is tube-in-tube structure with the leading screw lift-bolt cover 3 of lower part.Valve retainer grapple 6 and locating shaft 8 all adopt copper material.
Specific embodiment is narrative but not determinate, does not limit protection scope of the present invention with this.The positioning screw length overall is 180mm; Thread segment is M10 * 1.5mm length 100mm.Support is circular, height 60mm.The valve retainer grapple is a copper material, so can not cause hard defects to destroy to valve retainer and cylinder cap.Valve retainer grapple and locating shaft all are detachable blocks, can change different grapples at different head valve seat rings; Can change the locating shaft of different-diameter at the valve guide bushing size of cylinder cap.The locating shaft that is inserted in the valve guide bushing also is a copper material, so can avoid the head valve conduit is caused damage.The circular planes frame of elder generation's support covers the valve retainer on the cylinder cap during use, locating shaft with positioning screw partly is inserted in the head valve conduit then, adjust screw position up and down, by moving on the conical surface expansion positioning disk, the valve retainer grapple is opened, hook the valve retainer bottom with 3 120 ° of uniform grapples, use the setscrew nut tie down screw.Constantly slowly screw with spanner (injecting six quadrate part branches of hoisting nut), drive leading screw lift-bolt cover by hoisting nut and rise, leading screw lift-bolt cover drives on the valve retainer grapple and moves, and valve retainer is extracted in cylinder cap.
Characteristics of the present invention and beneficial effect are, the present invention utilizes the leading screw lever principle can interference fit for convenience detach to be fitted in valve retainer on the cylinder cap, and in the process of dismounting, can not cause damage to performance and valve retainer etc., the valve seat ring of diesel engine cylinder cover for different model adopts the different critical components such as grapple simultaneously. Can also get the bearing that pulls out different model engine flywheel end by changing different size conical surface expansion positioning disk, and in the process of dismounting, can not cause damage to bearing and valve retainer, have simple in structure, convenient flexibly characteristics.
