Dry-type airtight leakage testing machine for cylinder block production based on engine

Abstract

The invention discloses a dry-type airtight leakage testing machine for cylinder body production based on an engine. The dry-type airtight leakage testing machine comprises a box body mechanism and a connecting vertical rod connected with an internal bearing of the box body mechanism. A placement frame is fixedly mounted at the top end of the connecting vertical rod, a bidirectional lead screw is connected to the interior of the upper surface of the left end of the placement frame in a penetrating and bearing mode, and a clamping block a and a clamping block b are connected to the outer side of the bidirectional lead screw in a threaded mode; and an electric push rod is installed in a groove in the right end of the placing frame, the output end of the electric push rod is connected with the right end of an adjusting plate, and the right end of the adjusting plate is in clamped sliding connection with the interior of the right end of the placing frame. The engine-based dry-type airtight leakage testing machine for cylinder body production is provided with the air inlet pipe, yellow green colored nontoxic chlorine is injected into the air inlet pipe, detection is carried out through the chlorine, when gas leakage occurs, the gas leakage can be well observed through yellow green gas, and then detection and checking can be well carried out.

Description

technical field [0001] The invention relates to the technical field of manufacturing of an engine and an engine unit, in particular to a dry-type air-tight leak tester for cylinder block production based on an engine. Background technique [0002] The cylinder block of the engine needs to be tested for air tightness after the production and processing, so as to check whether the cylinder block is complete, whether there is air leakage, and whether it meets the later use requirements; [0003] The patent name disclosed with the announcement number "CN213933004U" is "A Novel Leak Test Device for Engine Cylinder Head Processing". Other leak test devices on the market can block the holes in all directions of the engine block. Compared with manual blocking, the operation is more convenient. However, this leak test device is detected by water and air, and the water will make the inside of the cylinder block wet. , in the later stage, drying work is required, and the operation is ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a dry-type airtight leak tester for cylinder block production based on the engine, so as to solve the problem that the current leak test device on the market proposed by the above-mentioned background technology is tested by water and air, and water will make the inside of the cylinder block wet. In the later stage, drying work is required, and the operation is more troublesome. At the same time, the air is a colorless and inactive gas. If a leak occurs during use, the staff's eyes can be used to observe, and the problem of leaking parts cannot be well checked.
