Abstract
The invention relates to a water detecting machine of an air cylinder cover hood of an engine. The water inspection machine is suitable for detecting sealability of the air cylinder cover hood of the engine by a water detecting mode. First, the air cylinder cover hood is placed on the upper surface of a bottom plate; piston rods of clamp air cylinders extend out; the air cylinder cover hood is clamped; holes at the top of the air cylinder cover hood are plugged by top hole plugging heads simultaneously during clamping; plugging mechanisms operate to plug holes in the side face of the air cylinder cover hood; an ejection air cylinder pushes a water tank to ascend to allow the air cylinder cover hood to be immersed in water completely; compressed air is charged into an inner cavity of the air cylinder cover hood through an air pipe below the bottom plate; and whether bubbles exist in the water is observed to detect the sealability of the air cylinder cover hood. The clamp air cylinders and air cylinders for the plugging mechanisms of the water detecting machine are arranged at the upper part of the water detecting machine and cannot be immersed in the water during work, so that the quality and the life of each air cylinder are ensured; and simultaneously, if the air cylinders have leakage, the sealability detection of the air cylinder cover hood is not influenced.
Description
Technical field
The present invention relates to a kind of cylinder cover for automobile engine water inspection machine, the mode that is applicable to examining by water is made sealing propertytest to engine air cylinder cap.
Background technology
Valve mechanism cover is the cover that is arranged on cylinder head top on engine, and its effect mainly contains: 1, prevent that external dust from entering cylinder head and body; 2, prevent that dust and foreign matter etc. from falling into and cause machine oil dirty, prevent that in addition machine oil from spilling and causing oil mass to lack; 3, protect the action of the movement parts such as valve lifter, rocker arm body; 4, low noise effect is fallen.If valve mechanism cover poor sealing, has leakage, just do not have its due protective action, affect performance and the operational effect of engine.Each enterprise mainly adopts water inspection method to the sealing propertytest of valve mechanism cover, first by clamp shutoff valve mechanism cover, again by valve mechanism cover submerged, by tracheae, to valve mechanism cover inner chamber, pass into pressurized air, if there is no bubble in water, valve mechanism cover sealing is qualified, otherwise, defective.The problem that current valve mechanism cover water inspection owner will exist is: the pneumatic elements such as the revolution clamping cylinder that clamping and plugging mechanism adopt, swing clamp cylinder, will be with valve mechanism cover submerged after clamping, shutoff, this has a great impact the quality of pneumatic element and life-span, if pneumatic element exists and leaks simultaneously, the sealing propertytest of valve mechanism cover will be affected.
Summary of the invention
The technical matters that the present invention solves has been to provide a kind of engine air cylinder cap water inspection machine, and the mode that is applicable to examining by water is made sealing propertytest to engine air cylinder cap.First valve mechanism cover is placed in to plate upper surface, clamping cylinder piston rod stretches out, and clamping cylinder housing blocks the hole at valve mechanism cover top by apical pore block head in the time of clamping; Each plugging mechanism action, the hole of shutoff valve mechanism cover side; Upper top gas cylinder promotes water tank and rises, and makes the complete submerged of valve mechanism cover; Again pressurized air is passed into valve mechanism cover inner chamber by the tracheae under base plate, observe in water and whether have bubble to emerge to detect the sealing of valve mechanism cover.The clamping cylinder of water inspection machine and each plugging mechanism are all arranged on water inspection machine top with cylinder, can submerged in the course of work, guarantee quality and the life-span of each cylinder, and if each cylinder exists and leaks simultaneously, also can not affect the sealing propertytest of valve mechanism cover.
Engine air cylinder cap water of the present invention inspection owner will be by frame, upper top cylinder mounting plate, upper top gas cylinder, the axis of guide, linear bearing, water tank, base plate, apical pore block head, back shaft, clamping cylinder installing plate, clamping cylinder, clamping pressure head, swing plugging mechanism, directly moving plugging mechanism forms; Upper top cylinder mounting plate is fixed in frame, and upper top gas cylinder, linear bearing are fixed on the cylinder mounting plate of top; Axis of guide one end is fixed on water tank bottom, and the other end is inserted in linear bearing; Upper top gas cylinder piston rod is fixedly connected with water tank bottom; Clamping cylinder installing plate is fixed in frame, and base plate and clamping cylinder installing plate support fixing by four back shafts; Rubber gasket is equipped with in four apical pore block head upper ends, and apical pore block head lower end is fixed on plate upper surface; Six clamping cylinders are fixed on clamping cylinder installing plate, clamp pressure head and are fastened on the piston rod of clamping cylinder; Swing plugging mechanism, directly moving plugging mechanism is fixed on plate upper surface.
