Description

Multi-station processing combination device for plug valve core fittings Technical Field The invention relates to the technical field of combined devices, in particular to a plug valve core accessory multi-station processing combined device. Background The plug valve is one of the most reliable and longest-service-life structures in cut-off valves, and has the performance core of interference fit between the valve core and the valve body and uniform fastening of end cover bolts. Because the plug valve core and the valve body are sealed by interference fit, the traditional production line completes press fitting, end cover assembly and bolt tightening in different devices. The valve core is manually knocked during press fitting, the pressing force is uncontrollable, the end cover and the valve body are required to be carried for a second time after being assembled, coaxial offset is easy to generate due to repeated positioning, the bolt tightening depends on a hand-held spanner, the workload is large, each working procedure is independently operated and cannot be continuously completed in the same clamping state, the sealing reliability is completely dependent on the skill of workers, the efficiency is low, and the quality fluctuation is large. Therefore, a multi-station combined mechanism capable of continuously completing press fitting, cap feeding and screwing in a single device is needed, so that uncertainty caused by repeated clamping and manual intervention is avoided.
