Multi-station rotary table for brazing operation

The multi-station rotary table comprises a working rotary table, a plurality of station assemblies are arranged on the working rotary table in the circumferential direction, each station assembly comprises a positioning cylinder, a positioning groove matched with a workpiece is formed in the upper end of each positioning cylinder, one side of each positioning cylinder is connected with a nitrogen supply pipe, and the other side of each positioning cylinder is connected with a nitrogen outlet pipe. The nitrogen supply pipes are communicated with the positioning grooves, and a nitrogen supply device is installed on the working rotary disc and connected with the nitrogen supply pipes. The multi-station rotary table for brazing operation is simple in structure, after a workpiece is installed on the positioning cylinder, the nitrogen supply device blows nitrogen to the positioning groove, the nitrogen can be continuously blown out from a groove opening of the positioning groove and the interior of the workpiece, t
