Description
Technical field
The invention belongs to frock clamp field, be specifically related to a kind of engine valve lock clamp dismantling device and assembly and disassembly methods.
Background technology
The valve of engine is the access way of combustion chamber gases, at work by moving back and forth the keying realizing valve, will bear great alternation and shock loading during motion; In prior art, the closedown of valve has come by valve spring, spring carries out the spacing pretightning force transmitting closedown valve by valve spring holder, and valve collet is then carry out spacing parts to valve spring holder, for ensureing that valve spring is used for closing the pretightning force of valve; Valve collet is two halves formula structure, and the outer surface of valve collet is the conical surface of joining with valve spring holder internal face kissing, and inner surface is the semi-circular boss of joining with valve stem head recess kissing; In order to ensure that valve spring is used for closing the pretightning force of valve, when dismantling valve collet and installing, need to ensure that the surface of valve collet is not scratched; But to the dismounting of valve collet and installation in prior art, maintenance personal's general valve bow or ordinary cartridge press, have knocked dismounting and the installment work of valve collet to valve spring holder.Because used instrument is not specific purpose tool, cause its operating procedure very unreasonable, so may to the surface tear of valve stem and valve collet in the process of dismounting valve collet, but these scuffings are not easily discovered, and within the short time of engine operation, also there will not be fault, only have by long work, fault just can show, and at this time cannot retrieve.So the method for this dismounting of maintenance personal and installation valve collet is irrational.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the object of the invention is to propose a kind of engine valve lock clamp dismantling device and assembly and disassembly methods.
The present invention adopts following technical scheme for completing above-mentioned purpose:
A kind of engine valve lock clamp dismantling device, described dismantling device includes valve spring holder pressure head, valve collet pressure head and handle; There is centered by described valve spring holder pressure head the cylindrical shell of step through-hole, and the step through-hole that valve spring holder pressure head center has is up big and down small structure; Described valve collet pressure head is positioned at the central through hole of described valve spring holder pressure head, and can slide up and down in the central through hole of valve spring holder pressure head; The locker pressure head spring that valve collet pressure head is resetted is equipped with in the upper end of described valve collet pressure head; Described valve collet pressure head is electromagnet structure, in order to when dismantling valve collet, by valve collet sucking-off from valve stem, completes the dismounting of valve collet
;described handle is arranged on the upper end of valve spring holder pressure head; Valve collet pressure head described in correspondence is provided with the power supply controlling magnet switching electricity;
The bottom surface of described valve spring holder pressure head is ring surface, and the bottom surface of valve spring holder pressure head and the valve spring holder of engine valve corresponding, in order to when dismounting valve collet, valve spring holder pressure head contacts with valve spring holder, under the effect of handle, valve spring holder pressure head overcomes the downward air compression spring seat ring of valve spring elastic force upwards between valve spring holder and cylinder head, and valve spring holder is separated with valve collet;
Centered by described valve collet pressure head, there is valve rod aperture and middle and lower part has the cylinder of annular boss, on valve collet pressure head, described annular boss is positive stop lug boss, the external diameter of annular boss be greater than valve spring holder pressure head center there is the minimum diameter of step through-hole, be less than valve spring holder pressure head center there is the maximum gauge of step through-hole, the bottom surface of described valve collet pressure head is ring surface, and the bottom surface of described valve collet pressure head is lower than the bottom surface of valve spring holder pressure head, namely between the bottom surface of valve collet pressure head and the bottom surface of valve spring holder pressure head, there is the space of locating valve collet, when dismantling valve collet, the downward air compression spring seat ring of valve spring holder pressure head, valve collet is separated with valve spring holder and enters in the space that has between valve collet pressure head bottom surface and valve spring holder pressure head bottom surface, the bottom surface of valve collet pressure head is contacted with valve collet, continue in the process pressed down at valve spring holder pressure head, valve collet pressure head overcomes the downward elastic force of locker pressure head spring and upwards bounces back along the central through hole of valve spring holder pressure head,
Described valve rod aperture is corresponding with the valve stem of valve to be arranged, in order to when dismantling valve collet, and the downward air compression spring seat ring of valve spring holder pressure head, valve stem enters valve rod aperture, ensures that the gentle door bar of valve collet dismantling device is on same axis; Continue in the process pressed down at valve spring holder pressure head, valve collet all enters in the space that has between valve collet pressure head bottom surface and valve spring holder pressure head bottom surface, and the electromagnet energising then on valve collet pressure head is by the valve collet sucking-off in valve stem; When installing valve collet, the downward air compression spring seat ring of valve spring holder pressure head, valve stem enters valve rod aperture, ensures that the gentle door bar of valve collet dismantling device is on same axis; Continue in the process pressed down at valve spring holder pressure head, the boss of valve collet enters in groove corresponding on valve stem, completes the installation of valve collet.
