Abstract

A tooling used for testing the gas tightness of a cylinder head cover belongs to a test tooling, and comprises a bottom plate, a top plate, a plurality of supporting columns and a plurality of cylinders. The supporting columns are connected between the bottom plate and the top plate, a rubber gasket used for plugging an opening at the bottom of the cylinder head cover is connected on the bottom plate, and the cylinders are connected on the top plate; the piston rods of the cylinders are connected with push plates on which a first push rod, a second push rod, a third push rod, a fourth push rod and a fifth push rod used for plugging a first through hole, a second through hole, a third through hole, a fourth through hole and a fifth through hole on the cylinder head cover are connected respectively, and the fourth push rod is equipped with an air inlet communicated with the fourth through hole. The advantage of the tooling used for testing the gas tightness of the cylinder head cover of the utility model is that the test efficiency of the gas tightness of the cylinder head cover can be improved.

Description

Be used for the bubble-tight frock of tested cylinder housing

Technical field:

The utility model relates to a kind of frock, specifically is a kind of bubble-tight frock of tested cylinder housing that is used for.

Background technology:

Valve mechanism cover in use; Because defective such as the sand hole that has or micro-cracks and produce the phenomenon of leakage of oil on the valve mechanism cover sidewall comes into the market in order to prevent the valve mechanism cover with these defectives, this just requires before dispatching from the factory, will valve mechanism cover to be detected sometimes; And detect the common method that the valve mechanism cover sidewall whether can leakage of oil is to carry out air tightness test; During test, as shown in Figure 3, because valve mechanism cover 13 upper surfaces are provided with first through hole 14 that communicates with inner chamber, second through hole 15, third through-hole 16, fourth hole 17, fifth hole 18 and bottom opening 19; Therefore; Before to valve mechanism cover 13 test, people need be blocked first through hole 14, second through hole 15, third through-hole 16, fourth hole 17, fifth hole 18 and bottom opening 19 through plug, put it into then in the water; Be connected with draft tube on the plug of shutoff fourth hole 17; Feed gas through this draft tube to valve mechanism cover 13 inner chambers, have or not bubble to emerge, whether come test passes through observing on the valve mechanism cover 13.Because in the process of shutoff first through hole 14, second through hole 15, third through-hole 16, fourth hole 17, fifth hole 18 and bottom opening 19; People adopt manual mode to carry out shutoff one by one; And can take great amount of time so undoubtedly; Cause the used time of impermeability of each valve mechanism cover 13 of test longer, testing efficiency is lower.

The utility model content:

The technical matters that the utility model will solve is, provide a kind of and when tested cylinder housing impermeability, can effectively shorten the test duration, thereby improve testing efficiency be used for the bubble-tight frock of tested cylinder housing.

The technical solution of the utility model is; Provide a kind of have a following structure be used for the bubble-tight frock of tested cylinder housing: comprise base plate, top board, a plurality of support column and a plurality of cylinder; Support column is connected between base plate and the top board; Be connected with the rubber blanket that is used for shutoff valve mechanism cover bottom opening on the base plate; Cylinder is connected on the top board; Be connected with push pedal on the piston rod of cylinder, be connected with first push rod, second push rod, the 3rd push rod, the 4th push rod and the 5th push rod of first through hole, second through hole, third through-hole, fourth hole and the fifth hole that are respectively applied on the shutoff valve mechanism cover in the push pedal, the 4th push rod is provided with the air admission hole that communicates with fourth hole.

After adopting above structure; Compared with prior art; The utility model is used for the bubble-tight frock of tested cylinder housing and has the following advantages: in use; Be placed on valve mechanism cover on the rubber blanket, through control cylinder the piston rod promotion push pedal on the cylinder is moved down, thereby first push rod, second push rod, the 3rd push rod, the 4th push rod and the 5th push rod that drive in the push pedal be pressed on first through hole, second through hole, third through-hole, fourth hole and the fifth hole respectively; Can block first through hole, second through hole, third through-hole, fourth hole, fifth hole and bottom opening fast; Have clamping the bubble-tight frock of tested cylinder housing that is used for of valve mechanism cover to be placed on water then, the air admission hole that is provided with through the 4th push rod can detect the impermeability of valve mechanism cover to the inner chamber bubbling air of valve mechanism cover.From the bubble-tight process that detects valve mechanism cover; We are not difficult to find out that first through hole, second through hole, third through-hole, fourth hole, fifth hole and bottom opening on the valve mechanism cover is with cylinder control shutoff simultaneously; Compare with existing manual shutoff; Save the time of shutoff one by one, thereby improved the bubble-tight testing efficiency of valve mechanism cover.

Description of drawings:

Fig. 1 is the perspective view that the utility model is used for the bubble-tight frock of tested cylinder housing;

Fig. 2 is that the utility model is used for the bubble-tight frock of tested cylinder housing and clamps the perspective view when valve mechanism cover is arranged;

Fig. 3 is the perspective view of valve mechanism cover.

Embodiment:

Below in conjunction with accompanying drawing and embodiment the utility model is used for the bubble-tight frock of tested cylinder housing and does further explain:

Like Fig. 1, Fig. 2 and shown in Figure 3; In this embodiment; The utility model is used for the bubble-tight frock of tested cylinder housing and comprises base plate 1, top board 8, four support columns 3, push pedal 9 and two cylinders 6; Four support columns 3 are connected between base plate 1 and the top board 8; Be connected with 2, two cylinders 6 of rubber blanket that are used for shutoff valve mechanism cover 13 bottom openings 19 on the base plate 1 and all be connected on the top board 8, the piston rod of these two cylinders 6 is connected to the two ends of push pedal 9; First push rod 12, second push rod 11, the 3rd push rod 10, the 4th push rod 7 and the 5th push rod 4, the four push rods 7 that are connected with first through hole 14 that is respectively applied on the shutoff valve mechanism cover 13, second through hole 15, third through-hole 16, fourth hole 17 and fifth hole 18 in the push pedal 9 are provided with the air admission hole 5 that communicates with fourth hole 17.

Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the protection domain of the utility model.
