The double guide rod cylinder 53 of the airtightness detection assembly 5 controls the air injection hole 57 to communicate with the oil injection hole of the workpiece, and ventilates the oil injection hole through the pneumatic connector 55, so as to feedback whether the information is qualified by detecting the corresponding air pressure gauge. The main air enters from the left end of the pressure gauge and exits from the right end, thereby entering the workpiece for inflation. When the pressure gauge shows 50Kpa, the PLC controls the air to be cut off. In the next 10s, if the pressure gauge value is between 45 and 50Kpa, it proves that the airtightness is good (OK). When it is lower than 45Kpa, it proves that the workpiece has serious air leakage and abnormal airtightness (NG).

[0045] After the air tightness detection process is completed, the clamping assembly 4 releases the swing arm 45, the first lifting assembly 2 lifts the workpiece, and the first driving cylinder assembly 12 drives the first lifting assembly 2 to move the workpiece to the side support assembly 7. The multiple groups of moving lifting mechanisms in the transmission assembly 6 move as a whole, and the workpiece is lifted and translated in sequence. The workpiece is horizontally transported under the drive of the second driving cylinder assembly 13, so that different batches of workpieces are transported in sequence at different workstations.

[0046] The integrated airtight oiling machine used for airtight detection of automobile front frames described in the embodiment of the present invention integrates the original processes of multiple scattered workstations into one device, which greatly improves the coordination between the various processes. At the same time, the improvement in the degree of automation also reduces the demand for manpower. The original configuration of one person per workstation is reduced to one person per multiple workstations to complete all the processes. Through the cooperation of multiple components in the equipment, the workpiece positioning and clamping, oiling detection, workpiece handling and other processes are accurately realized, and a standardized process is achieved through automated control. Compared with the existing technology, it saves labor costs and improves the consistency of product processing.
