At present, after the production of the vehicle-mounted massage armchair air bag is finished, in order to ensure the air tightness of the product, a side leakage test is required, and a special air bag air tightness detection device is required.
The traditional airtight testing mechanism for the air bag of the vehicle-mounted massage chair comprises a door-shaped frame, wherein a cross beam of the door-shaped frame is provided with a vertically arranged lower pressing cylinder, and the extending end of a piston rod of the lower pressing cylinder is positioned below and is connected with a lower pressing seat; the lower pressing seat is provided with a cavity, one side of the cavity is provided with an air inlet, and the bottom of the cavity is provided with a through hole; the lower part of the pressing seat is provided with a workpiece seat, the workpiece seat is provided with a workpiece hole, and the workpiece hole corresponds to the upper and lower positions of the through hole at the bottom of the cavity. When the air bag detection device is used, an air bag product to be detected is placed on a workpiece seat, and an air bag cavity of the product is inserted into a workpiece hole; then the lower pressing seat is driven to press downwards by the lower pressing cylinder, so that the upper end of the air bag product is compacted and sealed (the product is a rubber product and can be sealed after compaction); and finally, utilizing an external air supply device to supply air into the cavity from an air inlet hole of the cavity, and filling the air bag cavity of the product through a through hole at the bottom of the cavity. If the air bag cavity of the product is not air-leaking after being filled, the product is a qualified product; if the air bag cavity of the product leaks, the product is not acceptable.
However, to ensure that the position of the airbag product in the workpiece holder is accurate, the workpiece hole size in the workpiece holder is generally only slightly larger than the outer periphery of the airbag cavity of the product. When the air bag cavity of the product is inflated through the pressing seat cavity, the air bag cavity can be enlarged, the peripheral root part (namely the position corresponding to the workpiece hole) of the air bag cavity can be tightly attached to the inner wall of the workpiece hole, if flaws appear at the air bag cavity, the positions of the flaws can be blocked by the inner wall of the workpiece hole under the action of tightly attaching, whether air leakage exists at the positions can not be detected during airtight testing, and partial unqualified products can be misjudged as qualified products, so that the accuracy of testing results can not be ensured.
