Abstract
The invention relates to an airtightness test tooling for a water jacket of a vehicle engine air cylinder head. The airtightness test tooling comprises sealing gaskets, a plurality of main and auxiliary oil cylinders and a sunk oil cylinder, wherein the lower surface of an air cylinder head is provided with a plurality of water holes, a positioning block is arranged at a piston rod extending end of the sunk oil cylinder, the cylinder body of each main and auxiliary oil cylinder is fixedly arranged on the positioning block of the sunk oil cylinder, the piston rod extending end of each main and auxiliary oil cylinder is fixedly connected with a press block, and the other end of each press block is fixedly arranged in each water hole by each sealing gasket to plug the water hole. The airtightness test tooling has the advantages that the automatic operation is realized, the labor strength of operators is reduced, the production efficiency is improved by 3.5 times, the problem of leakage of screw holes during installation can be timely found, and the quality of the water jacket is improved.
Description
Technical field
The present invention 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.
Summary of the invention
The technical problem to be solved in the present invention is: in order to overcome above-mentioned technical matters, provide a kind of vehicular engine cylinder head jacket airtightness testing tool.
The technical solution adopted for the present invention to solve the technical problems 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 a further improvement on the present invention, 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 invention has the beneficial effects as follows, the present invention has 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, has improved product quality.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the enlarged drawing at the A place 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
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
With reference to figure 1, the present invention includes 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 invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
