Air tightness testing tool for car end connectors

Abstract

The invention discloses an air tightness detection tool for a vehicle end connector, which includes a cylinder, a frame and a blocking device; a cylinder connecting plate is arranged on the top of the frame; the cylinder is arranged on the cylinder connecting plate; the A liftable cylinder plate is provided below the cylinder connecting plate; an upper air pipe head is provided on the top of the cylinder plate; the air outlet of the cylinder is connected with the upper air pipe head; the blocking device includes a sealing gasket and a plurality of sealing Blocking member; the sealing gasket can be fixedly connected to the bottom of the cylinder plate; the bottom of the frame is provided with a bottom plate; the plurality of blocking members are respectively arranged on the bottom plate; the plurality of blocking members It includes a liftable blocking piece and a horizontally movable and liftable blocking piece. The tooling can ensure the reliability of the blocking effect by adjusting the position of the blocking parts, has strong adaptability to the product, improves the detection efficiency and reduces the misjudgment rate at the same time.

Description

technical field [0001] The invention relates to the technical field of air-tightness testing tooling, in particular to an air-tightness testing tooling for car-end connectors. Background technique [0002] In existing production, many product parts need to be tested for airtightness before leaving the factory to prevent defective parts such as perforation from entering the market. The main method of leak detection is to block the parts of the product first, and then inject a certain pressure of gas into the parts. After a period of time, check whether the gas pressure inside the parts is within the required range. However, in reality, it is difficult to detect the tightness. The main reason is that many parts have irregular shapes, and it is extremely inconvenient to block them. The fixing plate is an important part of the new energy vehicle battery pack. This part provides dustproof and waterproof sealing protection for the internal circuit of the battery pack, and this pa...

However, in reality, it is difficult to detect the tightness. The main reason is that many parts have irregular shapes, and it is extremely inconvenient to block them. The fixing plate is an important part of the new energy vehicle battery pack. This part provides dustproof and waterproof sealing protection for the internal circuit of the battery pack, and this part is one of the important connecting parts for the quick connection of the battery pack when charging. Accurately align and fasten the replacement car battery. There are many different faces on the surface of the parts, and the surface shape is complex. In the existing process, the holes are mainly blocked manually in advance, and then the gas is injected under pressure.

[0003] However, the detection efficiency of the above-mentioned traditional operation method is low, and it often takes a long time to test the tightness of a die-casting QP002 vehicle-end connector fixing plate, and the effect of artificially blocking the hole is often not particularly ideal, and it is prone to failure. The phenomenon of complete sealing, so it is easy to misjudge good parts
