Abstract
The utility model provides a kind of dismantling device for valve tappet, while realizes quickly assembling and dismounting operation, more can guarantee that the intact of the parts such as valve tappet.It includes stretching into the inserting end, joystick and connecting rod of valve tappet endoporus, and the inserting end is equipped with two by joystick protrusion and the contact of retraction.The utility model instrument can be realized in engine assembly and to the quick assembling of valve tappet and disassembled during disassembling, and operate rapid and convenient, have remarkable effect to improving engine production efficiency, engine assembly and disassembling quality.
Description
Technical field
It the utility model is related to machinery field, more particularly to engine manufacturing technology field.
Background technology
During the engine assembly put in camshaft, in order to realize the installation in valve tappet, usually by camshaft
After loading camshaft hole, it is put into by fabrication hole of the valve tappet from body upper end in tappet hole, finally so that cam crown of roll
Wheel withstands valve tappet.
Valve tappet mounting process method in engine manufacturing is typically：With a root long bar by valve tappet disclose into
Body inner cavity, then slowly moved valve tappet with stock, untill falling into valve tappet hole.There are following master for this method
Want problem：1st, when valve tappet falls into body inner cavity, can not ensure vertically to fall completely, the secondary periphery of tappet friction is easily knocked
Wound；2nd, most of valve tappet is required to tool bar adjustment and discloses into tappet hole, can installation is complete, efficiency of assembling is relatively low.
In addition, during engine stripping, it is necessary to after first taking out valve tappet, camshaft can be taken out, and due to gas
Stile post holes is with plane on body usually in more than 200mm, and common effective ways are in industry at present：It is barricaded as with valve actuating push rod
One scissor instrument, is stretched into valve tappet, valve tappet is taken out vertically upward out of hole, the method is asked there are following
Topic：1st, valve tappet and instrument coordinate clamps by manpower, and there are the risk departed from any time, fragile valve tappet in when taking-up；2nd, take
Take more when going out, it is low to disassemble efficiency.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of dismantling device for valve tappet, while real
Show quick assembling and dismounting operation, more can guarantee that the intact of the parts such as valve tappet.
For this reason, the utility model uses following technical scheme：
It includes stretching into the inserting end, joystick and connecting rod of valve tappet endoporus, and the inserting end is equipped with two and leads to
Cross the contact that joystick is prominent and bounces back.
On the basis of using above technical scheme, the utility model can also use scheme further below：
Joystick and inserting end are screwed by the connecting rod, and a root long axis, the length are passed through in the connecting rod
Axis connects a circular cone in inserting end, and outside diameter reduces the circular cone from the outside to the core, and the inserting end is on circular cone the inner
Two holes are provided with, two contacts are placed with hole.
The contact is ball.
Further, the ball is ejected inserting end outer surface in original state.
The circular cone is to be screwed with major axis.
A root long axis is passed through in the connecting rod, the major axis is connected with a button also through joystick and in tail end,
A spring is provided between the button and connecting rod, the spring slightly releases button outside joystick in off position.
The whole related circular cone of root long axis is outside, and ball can be fallen into inserting end by can make after lower button, conversely, after release button
The related circular cone of major axis is inwardly indented under the action of spring, while ball is ejected and is contacted tightly with valve tappet, can stretch into or
Extract valve tappet out.
As a result of the technical solution of the utility model, the utility model instrument can be realized in engine assembly and torn open
To the quick assembling of valve tappet and disassembled in solution preocess, operate rapid and convenient, to improving engine production efficiency, engine fills
Matching somebody with somebody and disassembling quality has remarkable effect.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Embodiment
The utility model is further elaborated below in conjunction with attached drawing.
Refer to the attached drawing 1, the utility model mainly include two parts, are inserting end 6 and joystick 3 respectively, connecting rod 5
Inserting end and joystick 3 are connected, and can conveniently be dismantled in connecting place using being threadedly coupled.
In the present embodiment, it is even more important that to be hollow in connecting rod, centre is cased with a major axis 9, and the major axis 9 is made
For inserting end 6 and major control transmission, connection and the functional component of joystick 3.
In the present embodiment, two holes are provided with the inserting end 6, contact 7, the contact are placed with two holes
Part 7 may be selected to be ball or other components that can be protruded and be retracted in hole, using round steel pearl in the present embodiment.The control
Spring 4 is provided with handle processed, which withstands connecting rod 5 and button 1, and the button 1 and major axis 9 are threaded connections 2.
In specific operating practice, original state：Lower button 1 is not pressed, and spring 4 ejects button 1, because button 1 and length
Axis 9 connects, and major axis 9 is connected in inserting end 6 with circular cone 8, therefore together to ejection direction, so ball is then ejected inserting end
6.Working status：By lower button 1, button 1, major axis 9, circular cone 8 are pressed down, and ball is fallen into hole, and surface is without departing from inserting end
6。
In operation process, stretched into by lower button 1 in valve tappet, release button 1 is so that at the extracting tool and its entrance hall
It is in close contact, it can be achieved that the extraction of valve tappet and stretching into operation.
