Abstract

The invention discloses an air tightness detection clamp, which relates to the machining field of the mechanical tool. The air tightness detection clamp comprises an air inlet pipe connector (5), wherein the air inlet pipe connector (5) is hinged with a clamping part (2); the clamping part (2) is provided with a protruded claw part (2-1) at the front part of a hinged position, and is provided with a handle part (2-2) at the rear part of the hinged position; and a shaft pin (2-3) is arranged between the hinged position and the handle part (2-2), the shaft pin (2-3) is movably plugged into a groove arranged on the air inlet pipe connector (5), and a spring (4) is arranged between the shaft pin (2-3) and the groove. Compared with the prior art, the problems of the existing air tightness detection tool that the efficiency is low and the labor intensity is large can be solved.

Description

technical field [0001] The invention relates to the field of mechanical tool processing, in particular to a fixture used for air-tightness testing of automobile air-conditioning pipe fittings. Background technique [0002] In order to ensure the airtightness and reliability of automotive air-conditioning pipe fittings, each air-conditioning pipe fitting needs to be tested for air-tightness after processing. Existing automobile air conditioner manufacturers test the airtightness of pipe fittings by putting the processed pipe fittings into water, passing test gas into the pipe fittings and observing whether there are bubbles coming out of the pipe fittings to determine whether the air tightness is good. And before the test gas is passed into the pipe fittings, if figure 1 The pipe fittings, the joint of the pipe fitting 1 needs to be butted through an intake pipe joint 5 with a compression nut 6 installed on the intake pipe; figure 2 As shown, during the connection process,...
