Description
Technical field
The utility model relates to tune-up instrument, particularly a kind of portable engine spiracle disassembling and assembling instrument.
Background technology
When engine is overhauled, need often dismounting and valve is installed, generally adopt Pneumatic dismounting instrument to complete dismounting action at present, but existing Pneumatic dismounting instrument existing following problem: 1, to need power supply and source of the gas; 2, source position fixed effect job area of being bullied is little, mobile inconvenient; 3, air delivering pipeline explosion and joint get loose and power can be caused to suddenly disappear, and cause the crowded wound of maintainer's hand or part to fly out, there is potential safety hazard.
For the production scene not having power supply, air pump, existing Pneumatic dismounting instrument cannot use, and can only utilize crowbar dismounting.Space, engine valve position is little, and valve spring elastic force is large, when dismounting valve, depresses cotter seat with crowbar, waits locking plate to expose and loosen rear Manual-disassembling locking plate, operation effort, inconvenient; In addition, the area that crowbar can contact with spring base little (when contact area is large, placing the annular groove of locking plate will be blocked), easy slippage, often occurs pointing and squeezes wound or part collapses the problem of losing.
Summary of the invention
The purpose of this utility model is to provide a kind of not by the restriction of power supply gentle source, conveniently moving, safe and reliable portable engine spiracle disassembling and assembling instrument, be applicable to site examining and repairing, the accidents such as finger crushes injury are avoided to occur, reduce the labour intensity of upkeep operation personnel, prevent part from collapsing and lose and damage, promote production operation efficiency.
The technical solution of the utility model is:
A kind of portable engine spiracle disassembling and assembling instrument, it is characterized in that: comprise L shape hooked arm, be built-in with transmission mechanism and be sleeved on the reduction box in the vertical armstand of L shape hooked arm, be located at the dish-type base of the horizontal gird front end of L shape hooked arm, be fixed as one with reduction box and the lever arm of horizontal gird keeping parallelism with L shape hooked arm, corresponding dish-type position base is located at the paw of lever arm front end, described transmission mechanism is secondary by Worm Wheel System, be located at the pinion on the worm gear place output shaft of Worm Wheel System pair, be located at the vertical armstand medial surface of L shape hooked arm and the tooth bar be meshed with pinion forms, the worm screw power intake of described Worm Wheel System pair is provided with hand wheel, described paw front center is provided with U-shaped breach.
The beneficial effects of the utility model are:
1, the reduction box be fixed as one with lever arm adopts Worm Wheel System secondary, and gearratio is large, simple to operate laborsaving, only needs alignment pieces swinging handle just can exert pressure easily or reduce pressure, completes the installation or removal of elastic part;
2, paw translational speed evenly, steadily, and have auto-lock function because of Worm Wheel System pair, and when stopping shake hand wheel, lever arm is parked in original place, can not move by External Force Acting, can not because of tong or the part ejection of jerking, safe and reliable;
3, volume is little, lightweight, is convenient for carrying, and uses not by place, environmental limit, does not need the auxiliary equipment such as power supply, air pump, and do not need to connect tracheae, electric wire, so can use in various place flexibly, flexibility is good.
