Skeleton sealing ring trimming machine double-knife clamping device

Abstract

The invention discloses a double-knife clamping device of a framework sealing ring edge trimmer. The double-knife clamping device comprises a clamping knife body, a connecting rod, a pressing plate, a pressing plate screw, a secondary knife clamping block, a secondary knife body, a main knife body, a locking screw and a secondary knife angle-adjusting scale, wherein the secondary knife clamping block comprises a clamping knife plate, a supporting plate, a clamping knife groove and a connecting hole; the clamping knife plate and the supporting plate are vertically distributed; the clamping knife groove is formed on the clamping knife plate; the connecting hole is formed in the supporting plate; the secondary knife clamping block is arranged on the clamping knife body through the supporting plate and fixedly connected by using the locking screw; an angle-adjusting clearance is reserved between the back surface of the clamping knife plate and the side face of the clamping knife body; the main knife body is arranged in a knife rod groove of the connecting rod; the connecting rod is sleeved in a knife rod hole and fixed by the locking screw; the secondary knife body is arranged in the clamping knife groove of the secondary knife clamping block and pressed by the pressing plate; and the secondary knife angle-adjusting scale is arranged between the clamping knife body and the supporting plate. The double-knife clamping device of the framework sealing ring edge trimmer can cut and trim internal and external rings of a framework sealing ring at the same time and is high in flash removing speed and high in processing accuracy.

Description

Technical field: [0001] The invention relates to a frame sealing ring flash trimming machine, in particular to a tool clamping device for a skeleton sealing ring flash trimming machine. Background technique: [0002] Since the skeleton sealing ring is generally molded, there are molding flashes on the sealing lips of the inner and outer rings of the molded sealing rings, which must be trimmed to remove flashes. At the same time, the requirements for removing flashes are very high. The roundness of the inner and outer rings and The coaxiality between the two has a great influence on the sealing performance. If the removal of the flash cannot meet the specified requirements, the sealing performance of the sealing ring will be greatly reduced. In severe cases, the seal will fail and cannot be used normally. At present, two trimming machines are usually used in this industry to cut and trim the inner ring and outer ring of the skeleton sealing ring respectively to remove flash. ...

AI Technical Summary

Problems solved by technology

Not only does it require two trimming machines, the investment is large, the equipment occupies a large area, and the trimming process is long. Moreover, each skeleton sealing ring has to be clamped twice, which can easily cause the inner and outer rings to be out of concentricity, that is, the coaxiality is too high. Poor, the processing accuracy of the skeleton seal is difficult to guarantee, and this trimming process cannot meet the processing requirements of the high-precision skeleton seal ring
