Abstract
The utility model relates to an engine cylinder cover water sleeve tightness test tool used for automobiles. The test tool comprises sealing gaskets, a plurality of primary-secondary oil cylinders and a sinking oil cylinder; a plurality of water holes are distributed at a lower surface of a cylinder cover; a positioning block is arranged above an extending-out end of a piston rod of the sinking oil cylinder; the cylinder body of each primary-secondary oil cylinder is fixed on the positioning block of the sinking oil cylinder; an extending-out end of a piston rod of each primary-secondary oil cylinder is fixedly connected with one press block; and the other end of each press block is fixed in one water hole through one sealing gasket so as to plug the water hole. With the engine cylinder cover water sleeve tightness test tool used for the automobiles of the utility model adopted, automatic operation can be realized; labor intensity of an operator can be reduced; production efficiency can be increased by 3.5 times; and the problem of leakage existing in mounting screw holes can be timely discovered; the quality of products can be improved.
Description
Technical field
The utility model relates to the airtight technical field of engine cylinder cap, especially a kind of vehicular engine cylinder head jacket airtightness testing tool.
Background technology
Vehicular engine cylinder head jacket air-tight test is the critical process that prevents that vehicular engine from leaking, because the cylinder head lower plane is arranged 16 little spacing φ 5 ~ φ 8 water holes, traditional way is to adopt at the soft oil resistant skin of cylinder head lower plane pad at present, utilize 18 installation screws of cylinder head to be immersed in the water inspection with bolt after only being locked into, operative employee's labour intensity is large, efficient is low and the difficult problem of finding the installation screw seepage but this method exists.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome above-mentioned technical matters, provide a kind of vehicular engine cylinder head jacket airtightness testing tool.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of vehicular engine cylinder head jacket airtightness testing tool, comprise sealing gasket, a plurality of primary-secondary oil cylinders and sinking oil cylinder, described cylinder head lower surface arrangement has a plurality of water holes, described sinking cylinder piston rod external part top is provided with locating piece, the cylinder body of each primary-secondary oil cylinders is fixed on the locating piece of sinking oil cylinder, the piston rod external part of each primary-secondary oil cylinders is fixedly connected with briquetting, and the briquetting other end is fixed in by sealing gasket and makes its shutoff in the water hole.
As further improvement of the utility model, the two ends of described locating piece also are provided with the clamp that the cylinder head both ends of the surface are clamped.
The beneficial effects of the utility model are, the utility model has been realized automated job, has alleviated operative employee's labour intensity, and production efficiency improves 3.5 times, and can in time find the problem of installation screw seepage, have improved product quality.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A place enlarged drawing of Fig. 1.
Among the figure: 1. sealing gasket, 2. briquetting, 3. primary-secondary oil cylinders, 4. sinking oil cylinder, 5. locating piece, 6. cylinder head, 7. clamp.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
With reference to figure 1, the utility model comprises sealing gasket 1, a plurality of primary-secondary oil cylinders 3 and sinking oil cylinder 4, cylinder head 6 lower surface arrangement have a plurality of water holes, sinking oil cylinder 4 piston rod external parts top is provided with locating piece 5, the cylinder body of each primary-secondary oil cylinders 3 is fixed on the locating piece 5 of sinking oil cylinder 4, the piston rod external part of each primary-secondary oil cylinders 3 is fixedly connected with briquetting 2, and briquetting 2 other ends are fixed in by sealing gasket 1 and make its shutoff in the water hole; For cylinder head 6 can be kept when moving up and down firmly, the two ends of locating piece 6 also are provided with the clamp 7 that cylinder 6 lid both ends of the surface are clamped.
Adopt after improving in 3 pairs 16 the little spacing φ 5 ~ φ 8 water hole shutoff of primary-secondary oil cylinders of cylinder head 6 lower planes, and compression interlock sinking oil cylinder 4 is immersed in the water cylinder head 6, delay time and checked that finishing rear the rising unclamped workpiece in 2 minutes, realized automated job, alleviated operative employee's labour intensity, production efficiency improves 3.5 times, and can in time find the problem of installation screw seepage.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
