[0017] The utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0018] As Figures 1 to 4In the embodiment of the graphite round bar precision turning device of the present utility model shown, the graphite round bar precision turning device includes a turning machine tool 1. On one side of the turning machine tool 1, there is a rotatable drum 2. At both ends of the drum 2, there are three-jaw chucks 3. On the other side of the turning machine tool 1, there is a support seat 4 slidably connected. On the support seat 4, there is a positioning chuck 5 coaxial with the three-jaw chuck 3. On the positioning chuck 5, there are three relatively movable jaws 6. On the opposite sides of the three jaws 6, there are rotatable rollers 7 respectively. On the turning machine tool 1, there is a slide seat 8 slidably connected. On the slide seat 8, there is a bracket 9 that can move back and forth slidably connected. On one side of the bracket 9, there is a tool rest 10. On one side of the tool rest 10, a turning tool 11 is fixedly installed. On one side of the tool rest 10, two arc-shaped dust suction covers 19 are connected by bolts. On the opposite sides of the two dust suction covers 19, a number of dust suction holes are respectively provided. By clamping one end of a relatively slender graphite round bar by the two three-jaw chucks 3, and the other end of the graphite round bar contacts the rollers 7 on the three jaws 6, the three-jaw chuck 3 drives the graphite round bar to rotate, and the rollers 7 on the three jaws 6 play a limiting role on the other end of the graphite round bar, avoiding the problem that the graphite round bar deviates during rotation and then breaks. By connecting the dust suction cover 19 to a negative pressure dust suction device, and slowly moving the turning tool 11 left and right, the high-speed rotating graphite round bar can be precisely turned, and the turned powder can be sucked by the dust suction cover 19, thus avoiding large pollution of the environment by the powder.

[0019] In an embodiment of the present application, preferably, inside the dust suction cover 19, there is a connector 12 connected. The two connectors 12 are connected to a Y-shaped dust suction hose 13. The dust suction hose 13 is connected to a negative pressure dust suction device. The dust suction hose 13 can connect the two dust suction covers 19, so that the two dust suction covers 19 can suck dust through one negative pressure device.

[0020] In an embodiment of the present application, preferably, on the turning machine tool 1, there is a relief groove. On the drum 2, there is a driven gear 14 fixed. Inside the relief groove, a motor is fixedly installed. The output end of the motor is fixedly installed with a driving gear 15. The driving gear 15 meshes with the driven gear 14. By starting the motor to drive the driving gear 15 to rotate, the driven gear 14 and the three-jaw chuck 3 can be driven to rotate.

[0021] In an embodiment of the present application, preferably, on one side of the turning machine tool 1, there is a rotatable screw rod 16. The slide seat 8 is threadedly connected to the screw rod 16. By rotating the screw rod 16, the slide seat 8 can be driven to move left and right.

[0022] In an embodiment of the present application, preferably, the arc openings of the two dust suction covers 19 are arranged oppositely, so that the two dust suction covers 19 can cover the outside of the graphite round bar, thereby enhancing the dust removal effect.

[0023] In one embodiment of the present application, preferably, a connecting block 17 is fixed to one side of the sliding seat 8. A knob 18 is threadedly connected to the connecting block 17. One end of the knob 18 is rotatably connected to the bracket 9. By rotating the knob 18, the front and back movement of the bracket 9 can be adjusted.

[0024] When the present utility model is in use, one end of a relatively slender graphite round bar is clamped by two three-jaw chucks 3. The other end of the graphite round bar contacts the rollers 7 on the three jaws 6. The front and back positions of the turning tool 11 are adjusted. The motor is started to drive the driving gear 15 to rotate, and then the driven gear 14 and the three-jaw chuck 3 can be driven to rotate. The three-jaw chuck 3 drives the graphite round bar to rotate, and the rollers 7 on the three jaws 6 play a limiting role on the other end of the graphite round bar, avoiding the problem that the graphite round bar deviates during rotation and thus causing the graphite round bar to break. The dust suction hose 13 is connected to a negative pressure dust suction device. The dust suction hose 13 can connect the two dust suction covers 19. By slowly moving the turning tool 11 left and right, the high-speed rotating graphite round bar can be precision turned, and the powder cut during turning can be sucked by the dust suction cover 19, thus avoiding serious pollution of the environment by the powder.
