Description
Technical field
The utility model relates to the machining tool class of auto parts and components, especially a kind of vibration damper device special for inflation.
Background technique
Vibration damper is the decay for accelerating vehicle frame and body vibrations, to improve a kind of component of ride of vehicle, travelling comfort, all vibration damper is housed in the suspension system inside of most of automobile.Inflatable vibration damper is simple as a kind of structure, and the retarder of function admirable is extensively applied.As its name suggests, it is in production and processing for inflatable vibration damper, must have one inflation operation.Conventional pneumatic equipment: the difference of vibration damper manufacturing enterprise development scale and production technology and the gas filling technology occurred is also different, has two kinds of special chargers of vibration damper: the first oscillating damper inflation welding machine in the market; The second multipurpose oscillating damper inflation machine.The first vibration damper is bottom inflatable, the second vibration damper is waist inflation, vibration damper bottom inflatable is the same with the working principle that waist is inflated, fuel-injection pump bottom or fuel tank waist bore an aperture, first aperture is sealed with nylon stopper before assembling product, assemble rear injection shock absorber oil test performance and sealed, vibration damper after completion is put upside down or is lain on inflatable welding machine worktable and adjusts welding machine pressure, the parameters such as the height of weld interval and welding machine positioning tool, pull out the plumbous plug processed of nylon stopper replacing one be inserted on vibration damper and put into air-filled pore (plumbous plug processed and aperture have gap), startup welder switch fixture steps up vibration damper and starts inflation, after air pressure reaches requirement, welding machine welds aperture automatically.This type of inflation welding machine cost, about 350,000, can complete the inflatable welding work of 1920 products 8 hours every days.Shortcoming: many one drilling operatings of inflatable welding vibration damper; Also will first be sealed by aperture before oiling, nylon stopper has fallen to occur leakage of oil; Remove nylon stopper during welding and load plumbous plug processed, have more two auxiliary materials; Welding position leakage of oil and oil impregnate is easily there is after welding; Add equipment, personnel and material etc.
Multipurpose oscillating damper inflation machine is placed in inflator by common vibration damper, connecting rod is pressed onto seal clamp in end inflator and holds fuel tank tightly and make nitrogen enter clutch release slave cylinder along between piston rod and oil sealing under suppressing pressure, inflate taking-up vibration damper, nitrogen in clutch release slave cylinder and vibration damper form air-fuel mixture state, piston rod is moved up and down for several times, nitrogen to be separated with shock absorber oil from clutch release slave cylinder and to enter fuel tank, the shock absorber oil work in clutch release slave cylinder or static time keep state of having one's bosom filled with under pneumatic pressure always.This type of inflator cost, about 200,000, can complete 2618 product inflations 8 hours every days.Shortcoming: the excessive fragile Sealing Performance of Oil Seal of inflation pressure, manufacturing efficiency is still lower.
Summary of the invention
The purpose of this utility model is exactly to solve the problems referred to above that Conventional pneumatic equipment and mode exist, and provide a kind of structure simple, low cost of manufacture, manufacturing efficiency is high, the vibration damper device special for inflation of good product quality.
Concrete scheme of the present utility model is: a kind of vibration damper device special for inflation, there is pneumatic head connecting base, pneumatic head connecting base is provided with central shaft hole, it is characterized in that: on pneumatic head connecting base, be also provided with radial air inlet hole be communicated with central shaft hole, at the top of pneumatic head connecting base, Oil sealing assembly is installed, and adopts upper union (screwed)bonnet (UB Oil sealing assembly and pneumatic head connecting base to be press-fited one; In the lower end of pneumatic head connecting base to being connected to charging air inlet, this charging air inlet epimere is thicker main paragraph, and hypomere is thinner introduction segment.
Charging air inlet described in the utility model adopts lower union (screwed)bonnet (UB and pneumatic head connecting base to fill to be integrated, and charging air inlet and pneumatic head connecting base interface are provided with O RunddichtringO.
Introduction segment wall thickness on charging air inlet described in the utility model is 0.3mm, diameter of bore and shock absorber piston rod Spielpassung.
The utility model structure is simple, low cost of manufacture, and application the utility model inflates from the oil seal lip at vibration damper top, change the mode of traditional bottom and waist inflation, charge operation is convenient, and manufacturing efficiency is enhanced about more than once, and quality of product is secure.
