Problems solved by technology

When the existing detection tool is used for detection, since the sealing plug is directly placed on the mouth of the fuel tank to seal the mouth, when the pressure of the compressed air used for detection is relatively high, it is prone to poor sealing, especially When the mouth is inclined, it affects the sealing effect of the sealing plug, which in turn affects the detection of the airtightness of the fuel tank

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] Such as figure 1 , figure 2 As shown, the compression tooling of the fuel tank air-tightness detection sealing plug of the present invention includes a sleeve 1 with a lower opening, a screw 2, and a joint pressure plate 3. The top of 1 is provided with a first connecting threaded hole, the upper end of the screw rod 2 is matched and set through the first connecting threaded hole, and the lower end of the screw rod 2 is hinged with the joint pressure plate 3 . After the casing 1 is fixed on the clamping upper part 8, by rotating the screw 2, the screw 2 can move up and down in the first connecting threaded hole, the screw 2 drives the joint pressure plate 3 to move up and down, and the rotating screw 2 can also move the sealing plug Compression and adjustment of compression force. The lower end of the screw rod 2 is hinged with the joint pressing plate 3, so that...

Abstract

The invention relates to the technical field of fuel tanks, in particular to a compression tool for the fuel tank airtightness detection sealing plug and an airtightness detection tooling, which includes a casing with a lower opening, a screw, and a joint pressure plate. There is a first connection fixing plate, the top of the casing is provided with a first connection threaded hole, the upper end of the screw rod is matched and set through the first connection threaded hole, and the lower end of the screw rod is hinged with the joint pressure plate. The sealing plug pressing tool is used to compress the sealing plug, reduce the possibility of the sealing plug being not tightly sealed, and ensure the sealing effect of the sealing plug. It is especially suitable for the case where the mouth of the fuel tank is inclined, and the structure is simple and easy to use. , the manufacturing cost and the operating cost are very low; since the sealing effect of the sealing plug is guaranteed, it is more convenient to carry out the air tightness test of the fuel tank, and the accuracy of the test result is improved.

Description

technical field [0001] The invention relates to the technical field of fuel tanks, in particular to a compression tool for a fuel tank air-tightness detection sealing plug and an air-tightness detection tool. Background technique [0002] The fuel tank needs to be tested for air tightness before use to ensure the safety of the fuel tank. The fuel tank air tightness detection is realized by the fuel tank air tightness detection tool. The existing fuel tank air tightness detection tool includes the clamping workpiece, the test water tank, the compressed air inlet component, the power cylinder, the sealing plug, and the sealing plug. It is used to seal the mouth of the fuel tank. The mouth of the fuel tank refers to the oil pump port, the vent valve port, the dump valve port, etc. The clamping workpiece includes the clamping upper part and the clamping lower part. It moves up and down under the action. In order to reduce the possibility of deformation of the fuel tank during d...
