[0015] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figures 1 to 3 As shown: An automatic arc milling device includes a frame 1 as a basis, a gearbox 2 is arranged on the frame 1, a milling cutter motor 3 is arranged at the input end of the gearbox 2, and a milling cutter 4 is arranged at the output end.

[0016] The frame 1 is also provided with a material rack, which is composed of a plurality of coaxial and equally spaced support blocks 5, the top surface of the support block 5 is an arc surface, and the frame 1 is also provided with a workpiece positioning cylinder 6, the position of the workpiece positioning cylinder 6 and the material rack are matched with each other, and a limit plate is provided on the opposite side of the workpiece positioning cylinder 6.

[0017] The frame 1 is also provided with a feeding and fetching mechanism, which includes an X-axis slide rail 7 and an X-axis motor 8. The X-axis slide rail 7 is slidably connected with an X-axis slide table 9. The working end of the X-axis motor 8 is connected to an X-axis lead screw 10. The X-axis lead screw 10 is connected to a nut block provided on the X-axis slide table 9. A Y-axis cylinder 11 is provided on the X-axis slide table 9. A clamping claw connecting plate 12 is provided at the working end of the Y-axis cylinder 11. Two symmetrically distributed clamping claws 13 are provided on the clamping claw connecting plate 12.

[0018] The milling cutter 4 and the material rack are both within the movement range of the clamping jaw 13.

[0019] A baffle 14 is also provided on the frame 1 , and a through hole is opened on the baffle 14 . The aperture of the through hole matches the outer diameter of the workpiece 15 to be processed. The feeding and picking mechanism can drive the end of the workpiece 15 to pass through the through hole and drive the workpiece 15 to contact the milling cutter 4 .

[0020] The working process of the automatic arc milling device of the embodiment of the utility model is as follows: the workpiece 15 is placed on the material rack by a loading manipulator (or by manual loading), specifically, on a plurality of support blocks 5. Since the top surface of the support block 5 is an arc surface, as long as the workpiece 15 of the bar material is placed on the support block 15, it can be automatically positioned. Then the workpiece positioning cylinder 6 is actuated to push the workpiece 15 to move along its own axial direction until the end of the workpiece 15 contacts the limit plate. At this time, the workpiece 15 is in a standard material taking position in space, and the workpiece positioning cylinder 6 is recovered;

[0021] Then the feeding and picking mechanism works, the Y-axis cylinder 11 extends, driving the two clamps 13 to move to the workpiece 15, the clamps 13 act, clamp the workpiece 15, and then the Y-axis cylinder 11 retracts, driving the workpiece 15 to the processing position; then the X-axis motor 8 works, driving the X-axis lead screw 10 to rotate, and then driving the X-axis slide 9 and all the mechanisms thereon to move along the X-axis direction. During this process, the end of the workpiece 15 will pass through the through hole provided on the baffle 14, and finally contact with the high-speed rotating milling cutter 4, and the milling cutter 4 will process an arc surface on the end face of the workpiece 15; and during the processing, due to the existence of the baffle 14, the cutting chips will not splash to the side where the feeding and picking mechanism is located;

[0022] After the processing is completed, the feeding and picking mechanism moves in the reverse direction, and the workpiece 15 that has been processed is placed back on the material rack, and the material picking robot (or manual picking method) picks up the material and transports the workpiece 15 to the next workstation.
