Problems solved by technology
[0003] The existing oil-cooled tube ball head leak detection tool is a gland matched with the ball head hole, which is done manually, and the leak detection work efficiency is low
In addition, ball heads with different specifications and models have different sizes. Each type of ball head needs to make a separate set of leak detection tooling, which cannot be used universally, resulting in long pipeline development cycles and high costs.

The invention discloses an oil-cooled tube bulb leakage detection fixture and a detection method thereof. The oil-cooled tube bulb leakage detection fixture comprises a motherboard, a lower movable block, a rubber gasket, an upper movable block, a top slab and a link mechanism, wherein the lower movable block is arranged on the motherboard, the link mechanism is arranged on the top slab, the link mechanism and the upper movable block are connected through a pressure lever, a bulb to be detected between the upper movable block and the lower movable block is sealed by the rubber gasket, and a quick coupling for connecting an air source is arranged on the upper movable block or the lower movable block. According to the oil-cooled tube bulb leak detection fixture and the detection method thereof, disclosed by the invention, the matching inside diameters (ID) of the movable blocks and the bulb are smaller, thus the oil-cooled tube bulb leakage detection fixture is suitable for bulbs in different sizes by being matched with the rubber gasket, and adapts to detect the leakage of bulbs and pipelines in different sizes through regulating the position of a nut on an adjusting screw rod, and has the advantages of simpleness and convenience in use, high leak detection efficiency, good generality and low cost.
Description
technical field [0001] The invention relates to the technical field of ball head leak detection, in particular to a ball head leak detection tool for an oil cooling tube and a leak detection method thereof. Background technique [0002] With the development of automobile technology, the quality requirements of automobiles are getting higher and higher. Among them, the pipeline structure of the oil cooling pipe of the automobile transmission is constantly innovating, and the sealing performance of the pipeline is very high, especially the sealing performance of the ball head of the oil cooling pipe. [0003] The existing oil-cooled tube ball head leak detection tool is a gland matched with the ball head hole, which is manually completed, and the leak detection work efficiency is low. In addition, ball heads with different specifications and models have different sizes. Each type of ball head needs to make a separate set of leak detection tooling, which cannot be used univers...
