Abstract
The utility model discloses a motor valve spring pressing tool. The technical scheme is that one end of a gantry support is provided with a support arm while the other end is provided with a long bolt; a gear is in shaft connection with the lower end of the support arm and is meshed with a rack; an operation rod and a rocker are in shaft connection at the center of the gear; the other end of the rocker is provided with a support rod of which one end is in shaft connection with the rocker; the other end of the support rod is embedded into the rack; a pull spring is arranged between a gear central shaft and the support rod; moment is formed among the rocker, the support rod and the pull spring; the gear is rotated by rotating the operation rod; the rack is leftwards moved by the meshing of the gear and the rack; a valve spring is placed between the long bolt and a pressing face of the rack, when the length distance for pressing the spring is achieved, the support rod is embedded in the rack to fix the pressing force, and at the moment the spring can be smoothly disassembled. The motor valve spring pressing tool is suitable for the valve spring positions with different distances, an operator can disassemble the valve spring in a laborsaving and smooth mode, the safety is good, the efficiency is high and the carrying is convenient.
Description
Technical field
The utility model belongs to the engine assembly instrument, is specifically related to a kind of provision for disengagement of engine valve spring.
Background technology
In engine working process, valve is by the valve spring return after opening, the valve spring installation site correctly whether, with engine, can work closely related.Will be by spring compression when installing or dismantle valve spring, the elastic force of valve spring is larger, being assemblied on production line of engine valve completed by special installation apparatus, and valve special installation apparatus cost is high, volume Portable belt very much not, only limits to the fixing machine bit manipulation.If therefore not by means of the equipment of special use, make the installation and removal of valve spring that certain difficulty be arranged, must under other people help, valve spring be depressed, and then complete installation or removal by the another one people.Therefore each dismounting time and effort consuming, and poor stability efficiency is low.In view of the foregoing, so if a kind of simple portable dismounting utensil is provided, be the essential of the industry.
Summary of the invention
The purpose of this utility model is, a kind of spring dismounting device for engine air valve tool is provided, and to solve the difficulty of engine valve assembling or maintenance, increases work efficiency, and protects simultaneously its Surrounding Parts injury-free.
Below in conjunction with accompanying drawing, know-why of the present utility model and structure are described.The engine valve spring compaction tool, have gantry shape support, support arm, action bars, gear, and tooth bar, spring and stay bolt etc., its technical scheme is: an end of gantry shape support is provided with support arm, and gantry shape support other end gear is provided with stay bolt.Gear is connected with support arm lower end axle, the wheel and rack engagement, central gear axis is equipped with action bars and rocking bar, the rocking bar other end is equipped with pole, pole one end is connected with rocker shaft, the other end embeds tooth bar, between central gear axis and pole, is provided with extension spring, between rocking bar, pole and extension spring three, forms moment.
Its principle is: by the rotating operation bar, gear is rotated, engagement by wheel and rack is moved to the left tooth bar, valve spring is placed between the pushing face of stay bolt and tooth bar, when the length distance that reaches holddown spring (thrust), pole is embedded to tooth bar in order to position is fixed, can unload smoothly lower spring this moment.
Characteristics of the present utility model and beneficial effect be, utilizes wheel and rack to produce displacement valve spring is compressed, and utilizes the moment that forms between rocking bar, pole and extension spring three, valve spring for convenience detach.And can adapt to the position that difference cylinder covers the different distance valve spring.The operator can complete the dismounting of engine valve spring laborsaving, gently, and security is good, and efficiency is high and be convenient for carrying.
The accompanying drawing explanation
Shown in accompanying drawing 1 be the utility model principle and overall structure schematic diagram.
The specific embodiment
Below by reference to the accompanying drawings and by specific embodiment know-why of the present utility model and structure to be further described.
The engine valve spring compaction tool, its structure is: an end of gantry shape support 1 is provided with support arm 2, and gantry shape support other end gear is provided with stay bolt 3.Gear 4 is connected with support arm lower end axle, wheel and rack 5 engagements.Central gear axis is equipped with action bars 6 and rocking bar 7, and the rocking bar other end is equipped with pole 8, and pole one end is connected with rocker shaft, and the other end embeds tooth bar, between central gear axis and pole, is provided with extension spring 9, between rocking bar, pole and extension spring three, forms moment.The one side of gear is provided with hexagonal hole, and action bars is provided with six square shafts, during operation, action bars is moved to the hexagonal hole of gear, gets final product transmitting gear.Rocking bar is the both arms of a U-shaped, and the termination of both arms is provided with through hole and is connected with central gear axis.The pushing face that is provided with foremost of tooth bar.
Structurally, action bars coordinates with gear by transmitting gear makes tooth bar produce displacement, valve spring is placed between the pushing face of stay bolt and tooth bar, by tooth bar, moves forward and reaches the purpose of holddown spring.Because spring is compacted, tooth bar has active force backward, so the pole termination will be embedded in tooth bar, by rocking bar and extension spring three, forms moment, to keep the state that compresses.This moment can light dismounting spring.
