Embodiment 1

[0033] refer to Figure 1-9 , a multi-purpose pneumatic sealing fixture, including a cylinder body 1 and a power output end 2 connected to the cylinder body 1, the end of the power output end 2 is provided with a limit block 3, and the limit block 3 is preferably screwed The nut at the power output end; the power output end 2 is set with an elastically deformable sleeve 4 between the limit block 3 and the cylinder body 1; the limit block 3 is provided with an output belt Gas outlet port 31 for compressed gas.

[0034] The casing 4 is preferably a silicone casing, which is wear-resistant, pressure-resistant, and recoverable after compression. Of course, the casing 4 can also be other elastic plastics.

[0035] During operation, firstly, the power output end 2 is incorporated into the water inlet of the radiator water chamber, and at this time, the diameters of the sleeve body 4 and the water inlet match. Then the power output end 2 moves to drive the sleeve body 4 to be compr...

Abstract

The invention belongs to the field of radiator machining equipment and discloses a multipurpose pneumatic sealing fixture. The pneumatic sealing fixture comprises an air cylinder body and a power output end connected to the air cylinder body, the tail end of the power output end is provided with a limiting block, and an elastically deformable sleeve located between the limiting block and the air cylinder body sleeves the power output end; the limiting block is provided with a gas outlet used for outputting pressurized gas. According to the fixture, the pressurized gas can be injected into a water chamber, and meanwhile it is ensured that the fixture can strictly seal a water inlet of the water chamber.

Description

technical field [0001] The invention relates to the field of radiator processing equipment, in particular to a multipurpose pneumatic sealing fixture. Background technique [0002] After the water chamber of the radiator is assembled to the core of the radiator, a leak test is required. [0003] The applicant's prior patent application ZL201520449475.9 discloses a leak detector for an oil cooler, including a water tank support, a water tank is provided on the water tank support, and a water tank that is at least partially capable of freely immersing is provided on the water tank. The movable bracket in the water tank, the movable bracket is provided with an oil cooler placement groove and two fixing devices for fixing the oil cooler on the oil cooler placement groove, and the fixing device is provided with a The ports for sealing connection of the oil cooler, and an air supply pipe is connected to one of the ports. [0004] This leak detector is also suitable for water-coo...
