Abstract
The utility model relates to a valve clearance automatic adjusting machine which is provided with the adjust screw driving force and the locking nut driving force of a coaxial output rocker arm, wherein a sleeve of a locking nut of an adjust screw of the rocker arm and a driven gear connected with the sleeve are sheathed on a power output shaft of the adjust screw driving force of the rocker arm in slide; the lower part and an output spline shaft of a driver in a shape like a Chinese character of yi / a sleeve form a key mat, and a compression spring is arranged on the upper end of the output spline shaft of the driver in a shape like a Chinese character of yi / a sleeve; a driving gear is connected to a power output shaft of the locking nut driving force, and is engaged with the driven gear. The driver in a shape like a Chinese character of yi and a sleeve wrench of the utility model are combined by two suits of dynamic force; as the utility model is accurately driven by a power device, the utility model automatically adjusts valve clearances, raises the production efficiency, drops labor intensity, and is convenient in operation.
Description
Technical field
The utility model relates to the engine valve regulation technology, specifically is that a kind of valve clearance is adjusted machine automatically.
Background technique
The valve clearance is the important adjustment of motor, the position of Control Parameter, and is very big to performance, the discharging influence of motor.Present adjustment is still adopted a word bottle opener, socket wrench to add black chi and is manually adjusted, and need repeat repeatedly to adjust, and it is not high to adjust precision, and it is low to adjust efficient, and intensity is big, and is higher to labor claim.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at prior art, provide a kind of valve clearance to adjust machine automatically, one word bottle opener, socket wrench are lumped together by two groups of power packages, and the accurate driving by power plant, reach automatic adjusting to the valve clearance, enhance productivity, reduce labor intensity, easy to operate.
The technical solution of the utility model is as follows:
The valve clearance is adjusted machine automatically, includes adjusting screw of rocker arm locking nut sleeve and adjusting screw of rocker arm and tightens a word bottle opener/sleeve.It has two groups of driving forces of coaxial output, is respectively adjusting screw of rocker arm driving force and locking nut driving force; Wherein, the adjusting screw of rocker arm driving force is fixed with the adjustment engine housing; its pto stretches in the housing; its upper sliding sleeve adjusting screw of rocker arm locking nut sleeve and the tight with it driven gear that connects; word bottle opener/sleeve output spline key is placed in the pto bottom; and at word bottle opener/sleeve output spline upper end portion installation pressure spring, word bottle opener/sleeve output spline lower end has adjusting screw of rocker arm and tightens a word bottle opener/sleeve; The locking nut driving force is fixed with adjusting engine housing by fixing frame, and its pto stretches in the housing, and output shaft tightens and connecting driving gear, and driving gear is meshed with driven gear.
The utility model adopts two groups of power combinations, two rotational powers of coaxial output, and once order is finished adjustment, the locking of valve clearance.Rotated by adjusting screw of rocker arm drive force one word bottle opener/sleeve output spline earlier, tighten the valve clearance and adjust bolt after do not have the gap, the several angle that reverses again (this angle is determined according to the gap) is locked this driving; The locking nut driving force drives driving gear more then, and transmission of power is given driven gear, and the locking nut sleeve rotates with it synchronously, tightens the valve clearance locking nut by fixed end taken about the point of fixation.Locking nut sleeve and adjusting screw of rocker arm are tightened a word bottle opener/sleeve and all can be slided up and down on live axle separately, and float about energy, adapt to the locking nut position different with adjusting screw and the error of their decentraction automatically.
This machine is applicable to all motors that the valve clearance is adjusted, and increases work efficiency and gap adjustment precision, reduces labor intensity, eliminates human error.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, this valve clearance is adjusted machine automatically and mainly is made up of housing 3, adjusting screw of rocker arm driving force 12, locking nut driving force 1, driving gear 4, driven gear 10, locking nut sleeve 8, a word bottle opener output spline 9 and parts such as a word bottle opener 7, pressure spring 11.Adjusting screw of rocker arm driving force 12 is fixedlyed connected with adjustment engine housing 1, its pto 6 stretches in the housing 1, its upper sliding sleeve adjusting screw of rocker arm locking nut sleeve 8 and the tight with it driven gear 10 that connects, one word bottle opener output spline, 9 keys are placed in pto 6 bottoms, and pressure spring 11, one word bottle opener output splines 9 lower ends are installed in a word bottle opener output spline 9 upper end portions have adjusting screw of rocker arm and tighten a word bottle opener 7.Locking nut driving force 1 is fixed with adjusting engine housing 1 by fixing frame 2, and its pto 5 stretches in the housing 1, and pto 5 tightens and connecting driving gear 4, and driving gear 4 is meshed with driven gear 10.
Claims (1)
