Problems solved by technology

[0002] The tightness of the automobile fuel tank is one of the bases for judging whether the automobile fuel tank is qualified. It needs to be tested before leaving the factory. The current conventional method is to test through water pressure. The existing pressure test device makes the automobile fuel tank pass through the clamp Fix it in the water tank, and then add water to the water tank for testing, the operation is cumbersome and the efficiency is low

Abstract

The invention discloses an automobile fuel tank pressure testing device, which comprises an upper cage frame, a lower cage frame, a water tank used for accommodating the upper cage frame and the lower cage frame, an upper cage frame lifting mechanism and a lower cage frame lifting mechanism, and is characterized in that the upper cage frame and the lower cage frame can mutually engaged so as to form clamping for a fuel tank; the upper cage frame lifting mechanism comprises a fixed frame arranged at the rear side of the water tank, the top part of the fixed frame is provided with an upper lifting motor, the upper lifting motor is connected to an upper lifting arm through a first lead screw lifting mechanism, the upper lifting arm is connected with the upper cage frame, and the upper lifting arm and the upper cage frame are of a separable structure; the lower cage frame lifting mechanism comprises a lower lifting motor arranged on the fixed frame, the lower lifting motor is connected to a lower lifting arm through a second lead screw lifting mechanism, and the lower lifting arm is connected with the lower cage frame; and the upper cage frame and the lower cage frame clamp and tightly hold the fuel tank and immerse the fuel tank into the water tank so as to perform a water pressure test on the fuel tank, and the sealing performance of the fuel tank is judged. The automobile fuel tank pressure testing device is simple and convenient to operate, and improves the test efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a pressure test device for an automobile fuel tank. Background technique [0002] The tightness of the automobile fuel tank is one of the basis for judging whether the automobile fuel tank is qualified or not. Before leaving the factory, it is necessary to carry out a sealing test. At present, the conventional method is to conduct the test by water pressure. The existing pressure test device makes the automobile fuel tank pass through the clamp. Fixed in the water tank, and then adding water to the water tank to test, the operation is cumbersome and the efficiency is low. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a pressure test device for an automobile fuel tank, which can conveniently conduct a water pressure test on an automobile fuel tank, determine the tightness of the fuel tank, and improve the test efficiency. [0004]...
