Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1, the cam-linked hydraulic-driven rotary-cut rounding machine comprises a frame 1, wherein a cutter holder 2, a single-roller seat 3 and a double-roller seat 7 are arranged on the frame 1, a single roller 4 is arranged on the single-roller seat 3, and a double roller 6 is arranged on the double-roller seat 7. The machine frame 1 is provided with a rocker core shaft 13 and a cam shaft 16 which are arranged below the double-roller seat 7 and penetrate through the machine frame 1, two rocker arms 10 are symmetrically hinged at two ends of the rocker core shaft 13, a connecting rod 8 is hinged on the rocker arms 10, the connecting rod 8 is hinged with a connecting rod seat 9 fixed on the double-roller seat 7 or the tool apron 2, and the rocker arms 10, the connecting rod 8 and the double-roller seat 7 form a rocker slider mechanism. One of the double-roller seat 7 and the tool apron 2 can do reciprocating rectilinear motion along the track on the machine frame 1 to realize advancing and retreating of the vehicle, when the double-roller seat 7 can do reciprocating rectilinear motion along the track on the machine frame 1, the connecting rod 8 is hinged with the connecting rod seat 9 fixed on the double-roller seat 7, and when the tool apron 2 can do reciprocating rectilinear motion along the track on the machine frame 1, the connecting rod 8 is hinged with the connecting rod seat 9 fixed on the tool apron 2. The machine frame 1 is fixedly provided with an oil cylinder seat 12, an oil cylinder 11 is hinged between the oil cylinder seat 12 and a rocker arm 10, two cams 14 are symmetrically and fixedly arranged at two ends of a cam shaft 16, the rocker arm 10 is provided with a roller 15, the roller 15 is attached to the outer edge of the cam 14, and the roller 15, the cam 14 and the rocker arm 10 jointly form a cam swing mechanism.
