Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1: a shell air tightness detection device is disclosed, as shown in fig. 1 and fig. 2, and comprises a case 1, a workbench 2 fixedly arranged on the case 1 and used for placing a shell, and a clamping mechanism 3 arranged on the case 1 and used for limiting the movement of the shell. An air charging hole 21 is arranged on the middle part of the working table 2, an air charging pipeline 11 communicated with the air charging hole 21 is arranged in the case 1, and a pressure gauge 12 is connected in the air charging pipeline 11.

As shown in FIG. 2, one side and the right side of the workbench 2 close to the operator are both fixedly connected with a limiting block 23 which is used for abutting against the edge of the shell to limit the shell through bolts. Meanwhile, a rubber sealing ring 22 for tightly abutting against the lower surface edge of the shell is adhered to the upper surface of the workbench 2.

As shown in fig. 1 and 3, the clamping mechanism 3 includes a first support 31 disposed in the housing 1 along the horizontal direction, a sliding frame 32 slidably disposed on the first support 31, a driving cylinder 33 fixedly disposed between the first support 31 and the sliding frame 32, a lifting cylinder 34 disposed on the sliding frame 32, and a pressing member 35 fixedly disposed at a lower end of a piston rod of the lifting cylinder 34 and used for pressing the upper surface of the housing; the pressing member 35 includes a pressing block 351 fixedly disposed at a lower end of the piston rod of the lift cylinder 34, and a rubber sleeve 352 adhesively disposed on a surface of the pressing block 351.
