Groove milling clamp for clamping and machining multiple workpieces on horizontal milling machine

The utility model relates to the technical field of machining, in particular to a groove milling clamp for clamping and machining a plurality of workpieces on a horizontal milling machine, which comprises a mandrel, a positioning block, a pressing plate, an oil-resistant rubber pad, an opening gasket, a compression nut, a first screw, a second screw and a third screw. The positioning block is installed on the inner side of the pressing plate through a second screw, and a long-strip-shaped semicircular positioning pin is arranged on the lower portion of the positioning block. One end of the mandrel is a stepped shaft, the opening gasket is sleeved on the stepped shaft, and the compression nut is in threaded connection with the outer end of the stepped shaft to compress the opening gasket. According to the device, the three-groove milling procedure can be completed by clamping multiple parts on the horizontal milling machine at one time, and the purpose of machining multiple parts at one time is achieved. 本实用新型
