Detailed Description
The first embodiment is as follows: as shown in fig. 1-3, the inner-cooling type composite vibration damping turning tool in the embodiment comprises a tool shank 1 and a tool bit 8 arranged at the front part of the tool shank 1, wherein a diamond-shaped blade mounting groove is formed in the front part of the tool bit 8, and a diamond-shaped blade 9 is arranged in the blade mounting groove. As shown in fig. 2, the tool bit 8 is provided with a pressing plate 7 at a position between the tool mounting groove and the tool holder 1, the pressing plate is formed by a pressing part 71 and a connecting part 72, the connecting part 71 of the pressing plate 7 extends and abuts against the diamond-shaped tool bit 9, wherein a threaded hole 10 is further formed at the position of the tool bit 8, the connecting part 72 of the pressing plate 7 is connected with the threaded hole 10 through a bolt 5, when the tool bit is mounted, the diamond-shaped tool bit 9 faces the tool mounting groove, the pressing part 71 of the pressing plate 7 is arranged above the diamond-shaped tool bit 9, the connecting part 72 of the pressing plate 7 faces the threaded hole 10, and the pressing part 71 of the pressing plate 7 abuts against and presses the diamond-shaped tool bit 9 through the bolt 5 in a screwing mode, so that the stability of the tool bit during tool processing is guaranteed, and the tool bit is convenient to replace.
