Technical Field

The invention belongs to the technical field of automobile engine manufacturing process equipment, and relates to an engine test technology. More specifically, the invention relates to a leakage test plugging tool for an oil passage of an engine cylinder block.

Background

For a new product sample stage of the cylinder body, manual leakage testing needs to be carried out on the oil duct of the cylinder body. Traditional leak test frock is very heavy to small batch volume work piece leak test, and because the leak test frock structure is complicated at the leak test in-process, is unfavorable for discovering the leak source, wherein bent axle hole oilhole shutoff difficulty to one side, and because here shutoff leads to whole leak test frock structure more complicated, uses very inconveniently.

Disclosure of Invention

The invention provides a leakage test plugging tool for an oil duct of an engine cylinder body, and aims to ensure reliable and efficient leakage test.

In order to achieve the purpose, the invention adopts the technical scheme that:

according to the leakage test plugging tool for the oil duct of the engine cylinder body, the crankshaft inclined oil hole is formed in the crankshaft supporting position of the engine cylinder body, the leakage test plugging tool is provided with the plugging pressing block, and the plugging pressing block is provided with the curved surface corresponding to the shape of the crankshaft supporting surface of the engine cylinder body.

And a PVC rubber is arranged between the crankshaft bearing surface of the engine cylinder body and the corresponding surface of the plugging pressing block.

The plugging pressing block is installed on the engine cylinder body through a fastening bolt and tightly presses the plugging pressing block and the crankshaft supporting surface of the engine cylinder body.

The fastening bolt penetrates through a bolt hole in the plugging pressing block and is screwed into a threaded hole in a combination plane of the engine cylinder body and the oil pan.

And an anti-abrasion boss is arranged on the outer end surface of the hole of the bolt hole on the plugging pressing block.

The plugging pressing block is made of aluminum material.

By adopting the technical scheme and adopting the manual leakage testing technology of the engine cylinder body, the reliability of leakage testing can be improved, and the efficiency can be improved; through the structural improvement of the oil duct leakage testing and plugging tool, the overall complexity of a manual leakage testing tool is reduced, and the manual leakage testing tool is more convenient to use; so that the PVC rubber sheet and the crankshaft hole generate interference fit, and the tight plugging of the crankshaft inclined oil hole is realized.

Detailed Description

The following detailed description of the embodiments of the present invention will be given in order to provide those skilled in the art with a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention.

As shown in figure 1, the structure of the invention is an engine cylinder block oil passage leakage test plugging tool, and a crankshaft inclined oil hole 3 is arranged at the crankshaft supporting position of an engine cylinder block 6. In order to overcome the problems and defects in the prior art and realize the purpose of the invention which can ensure reliable and efficient leakage test, the invention adopts the following technical scheme:

as shown in figure 1, the engine cylinder oil passage leakage test plugging tool is provided with a plugging pressing block 1, and the plugging pressing block 1 is provided with a curved surface corresponding to the shape of a crankshaft bearing surface of an engine cylinder.

By adopting the manual leakage testing technology for the engine cylinder body, the invention can ensure reliable and efficient leakage testing. Through oil duct leakage test shutoff frock institutional advancement, reduce the whole complexity of manual leakage test frock, improve the leakage test reliability.

And a PVC rubber sheet 2 is arranged between the crankshaft bearing surface of the engine cylinder body and the corresponding surface of the plugging pressing block 1.

The plugging pressing block 1 is installed on the engine cylinder body 6 through a fastening bolt 7, and the plugging pressing block 1 is tightly pressed with a crankshaft bearing surface of the engine cylinder body.

The specific scheme of the invention is as follows: the plugging tool penetrates through the bolt hole 4 on the plugging pressing block 1 through the fastening bolt 7, the plugging pressing block 1 is connected with the engine cylinder body 6, and the PVC rubber sheet 2 on the surface of the tool is in interference fit with the crankshaft hole, so that the oblique oil hole 3 of the crankshaft hole is plugged.

The fastening bolt 7 penetrates through the bolt hole 4 on the plugging pressing block 1, and the fastening bolt 7 is screwed into a threaded hole on a combination plane of the engine cylinder body 6 and the oil pan.

And an anti-abrasion boss 5 is arranged on the outer end surface of the bolt hole 4 on the plugging pressing block 1.

The blocking pressing block 1 is connected with an engine cylinder body 6 through a cylinder body bearing cover connecting bolt, so that the PVC rubber sheet 2 is in interference fit with a crankshaft hole, and tight blocking of the crankshaft inclined oil hole 3 is realized; wherein the wear-resistant boss 5 ensures the durability of the tool.

The plugging pressing block 1 is made of aluminum material. The leakage testing tool cost is reduced, and the leakage testing is more reliable and efficient.

The invention has been described above with reference to the accompanying drawings, it is obvious that the invention is not limited to the specific implementation in the above-described manner, and it is within the scope of the invention to apply the inventive concept and solution to other applications without substantial modification.
