Description

Airtight ejection testing mechanism for vehicle-mounted massage chair air bag

Technical Field

The utility model relates to a vehicle-mounted massage armchair gasbag detection device, a airtight ejection test mechanism for vehicle-mounted massage armchair gasbag specifically says so.

Background

At present, after the production of the vehicle-mounted massage armchair air bag is finished, in order to ensure the air tightness of a product, a side leakage test needs to be carried out, and a special air bag air tightness detection device needs to be used.

The traditional air tightness testing mechanism for the vehicle-mounted massage armchair air bag comprises a door-shaped frame, wherein a cross beam of the door-shaped frame is provided with a vertically arranged lower air cylinder, and the extending end of a piston rod of the lower air cylinder is positioned below and is connected with a lower pressure 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; and a workpiece seat is arranged below the lower pressing seat, a workpiece hole is formed in the workpiece seat, and the workpiece hole corresponds to the through hole in the bottom of the cavity in the up-and-down position. When the detection device is used, an airbag product to be detected is placed on a workpiece seat, and an airbag cavity of the product is inserted into a workpiece hole; then a pressing cylinder is used for driving a pressing seat to press downwards, and the upper end of the air bag product is compacted and sealed (because the product is a rubber product, the product can be sealed after being compacted); and finally, supplying gas into the cavity from the gas inlet hole of the cavity by using an external gas supply device, and filling the gas bag cavity of the product by the gas through a through hole at the bottom of the cavity. If the air bag cavity of the product is not subjected to air leakage after being filled, the product is qualified; the product is rejected if the air sac chamber of the product leaks.

However, in order to ensure that the airbag product is accurately placed in the workpiece seat, the size of the workpiece hole on the workpiece seat is generally only slightly larger than the periphery of the airbag cavity of the product. When aerifing to product gasbag chamber through pressing the seat cavity down, the gasbag chamber can be propped up, its periphery root (the position that corresponds with the work piece hole promptly) must be laminated with the inner wall in work piece hole closely, if the flaw appears here, under the effect of closely laminating, the flaw position can be stopped up by the inner wall in work piece hole, then can't detect out whether the condition of this position has the gas leakage when airtight test, then partly unqualified product can be judged by mistake as qualified product, can't guarantee the accuracy of test result.
