The utility model is achieved by the following technical programs:
A kind of diesel valve locker dismantling device, comprise afterburning lever fixture, point device and hold-down devices, described afterburning lever fixture comprises afterburning lever and support, described afterburning lever one end is fixed on the support, hold-down devices is positioned at the support downside, point device is arranged on two fuel injector construction bolts of support downside, comprise first adjustable plate, Adjusting bolt Adjusting screw, bearing flat plate and two sleeve pipes, described first adjustable plate upper end is hinged with support one end, the first adjustable plate lower end is threaded with the Adjusting bolt Adjusting screw upper end by regulating bolt, the Adjusting bolt Adjusting screw lower end is fixed on the bearing flat plate middle part by securing member, bearing flat plate two ends downside is bearing on the cylinder head by the sleeve pipe that is enclosed within on the fuel injector construction bolt respectively, and is fixed on the fuel injector construction bolt by the clamp nut that is positioned at the bearing flat plate upside; Described hold-down devices comprises second adjustable plate and spring wedge, and second adjustable plate upper end is hinged with support, is positioned at the sides adjacent of first adjustable plate, and the second adjustable plate lower end is hinged by adjusting rod and spring wedge upper end; Described spring wedge is corresponding with commentaries on classics cap position.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid diesel valve locker dismantling device, wherein said spring wedge comprise top board, with the vertical equally distributed several grab bar that links to each other of top board downside, the inboard tangent circle diameter of described several grab bars with change cap external diameter coupling.Trim ring is fixed on several grab bars inboard, and during use, described trim ring downside is resisted against changes the cap upside.
Aforesaid diesel valve locker dismantling device moves the back circular hole hinged with support outside the outside of second adjustable plate and support pin joint is provided with for second adjustable plate, be used for the dismounting of other model diesel engine locker.
The utility model structure is lightly compact, and an operator can finish whole operations.The utility model utilizes lever principle, only need afterburning lever one end is applied less downforce, according to principle of moment balance, the spring wedge has applied bigger downforce by changeing cap to the spring for valve of downside, thereby can take out or put into locker like a cork, and can the plucking air valve stem, damage draw-in groove, prolonged the service life of air valve stem, reduced the use cost of air valve.After the dismounting of finishing first locker, only need to rotate afterburning lever, the spring wedge is turned to second spring for valve to be changeed on the cap, gets final product second locker of direct dismounting, does not need to reinstall the utility model, very easy to use, has improved operating efficiency.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
