Detailed Description

The utility model is further illustrated by the following examples:

as shown in an embodiment in fig. 1, the full-automatic online leak detection device for the gearbox shell comprises a conveying line 1 and a detection module 2, wherein the conveying line 1 horizontally passes through the lower part of the detection module 2, the conveying line 1 comprises a conveying roller 11 and a conveying chain 12, and the conveying chain 12 is wound on and passes through the conveying roller 11; a supporting plate 13 is hinged to the conveying chain 12, a placing die 14 is fixedly assembled on the supporting plate 13, the lower portion of the shell 3 to be detected is placed on the placing die 14 in a sealing mode, the detection module 2 comprises a cylinder 21 in the vertical direction, the telescopic end of the lower portion of the cylinder 21 is connected with a closing plate 22, the closing plate 22 is opposite to the shell 3 to be detected which is assembled on the placing die and passes through the lower portion, when the shell 3 passes through the lower portion, the cylinder 21 moves downwards to press the closing plate 22 on the upper portion of the shell 3, a transition cavity 23 is machined in the closing plate 22, the transition cavity 23 is communicated with the interior of the shell 3, and the transition cavity 23 is communicated with the air pump 4 through a hose; the transition chamber 23 is connected to the air pressure measuring module 5. The casing 3 that this equipment mainly aims at is the casing that has open chamber on the upper and lower face, and these casings 3 only need seal the upper and lower face, just can have closed chamber in making casing 3.

In this embodiment, this equipment is mainly used for detecting gearbox housing 3, and this leak hunting equipment can directly link to each other with the production line of casing 3, and it is more convenient to use. When the full-automatic online leak detection device for the gearbox shell is used, the produced shell 3 directly enters the lower part of the detection module 2 through the placing die 14 on the supporting plate 13 of the conveying line 1, when the detection module 2 is finished, the shell is continuously conveyed to the lower part process through the conveying line 1, so that the shell 3 can synchronously run along with the production line of the conveying line 1 and the shell 3, people do not need to separately detect the shell 3 after independently dismounting the shell from the production line, meanwhile, the cylinder 21 on the detection module 2 pushes the sealing plate structure to be matched with the placing die to realize the internal sealing of the shell 3, so that the shell 3 can be internally provided with high pressure through the air pump 4, the inside and the outside of the shell 3 form pressure difference, when the shell 3 has cracks, gas can leak outwards, so that the internal pressure values of the shell 3 are different when the cracks exist and the cracks do not exist, and further, the air pressure change in the shell 3 is measured through the air pressure measurement module 5 to judge whether the air leakage exists in the shell 3, and the size of the crack occurring in the housing 3 can be inferred from the size of the change in the air pressure. In addition, the supporting plate 13 is hinged to the conveying chain 12, so that the supporting plate 13 can bend along with the conveying chain 12, the supporting plate 13 can rotate periodically along with the conveying chain 12, the supporting plate 13 does not need to be detached, and the use is more convenient.
