Detailed Description

The technical scheme protected by the utility model is specifically explained in the following by combining the attached drawings.

As shown in FIG. 1, a test fixture for nylon tube inspection sealing equipment mainly comprises: the clamp comprises a clamp bottom plate 1 and a support which is arranged on the clamp bottom plate and used for supporting a nylon pipe. In the embodiment, the nylon pipe to be detected has five pipe orifices, so that each pipe orifice is provided with a pressing block and a plug, wherein the first pipe orifice is provided with an air cylinder A206 and a plug A207, a piston rod of the air cylinder A206 is connected to the plug A207 through a connecting plate and used for controlling the movement of the plug A207, a pressing block B209 is further arranged above the first pipe orifice, and the pressing block B209 is driven by an air cylinder B208; similarly, a plug D213 and an air cylinder D212 for driving the plug D213 to move are arranged at the second pipe orifice, and a pressing block C211 and an air cylinder C210 for driving the pressing block C211 are arranged above the second pipe orifice; a plug G219 and an air cylinder G218 for driving the plug G219 to move are arranged at the third pipe orifice, and a pressing block E215 and an air cylinder E214 for driving the pressing block E215 are arranged above the third pipe orifice; a plug F217 and an air cylinder F216 for driving the plug F217 to move are arranged at the fourth pipe orifice, and a pressing block J223 and an air cylinder J222 for driving the pressing block J223 are arranged above the fourth pipe orifice; and a plug H221 and an air cylinder H220 for driving the plug H221 to move are arranged at the fifth pipe orifice. The device also comprises a bracket A201, a bracket B202, a bracket C203, a bracket D204 and a bracket E205 which are used for supporting the nylon tube. During operation, each pipe orifice is plugged by each plug, and the plugs are compressed by the compression blocks to ensure the sealing property of the plugs.

Furthermore, a sensor is arranged at each pipe orifice and used for detecting whether the pressing block at each pipe orifice is pressed in place or not and whether the pipe orifice is blocked by the plug or not, so that the leakage blocking of the pipe orifice is prevented.

In order to facilitate the model changing, handles 4 are respectively arranged on two symmetrical sides of the clamp bottom plate. When the model is changed, the test tool can be moved away for the model change only by detaching the fixing screw and lifting the handle 4.

The working principle of the utility model is as follows:

the test tool is arranged on a test machine table, a nylon pipe is placed on the test tool, a start button is pressed, a compression cylinder compresses the nylon pipe, and then a plug cylinder plugs each plug of the nylon pipe. The test instrument fills compressed air into the nylon tube through the test plug, measures the gas pressure change in the pipeline within a fixed time, and calculates whether the product has leakage or not and a specific leakage value according to the pressure change. And if the leakage rate is lower than the test standard, the product is tested to be qualified.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention, and all equivalent structures or equivalent processes performed by the present invention or directly or indirectly applied to other related technical fields are included in the scope of the present invention.
