[0017] Such as Figures 1 to 3In the embodiment of the graphite round bar eccentric through-hole drilling device of the present utility model shown, the graphite round bar eccentric through-hole drilling device includes a frame 1. A sliding seat 2 is slidably connected to the frame 1. A rotatable rotating shaft 3 is provided on the sliding seat 2. One end of the rotating shaft 3 extends out of the sliding seat 2 and is fixedly installed with a drill bit 4. A support 5 that can move up and down is provided on one side of the frame 1. A support tube 6 is provided inside the support 5. Outer edges are provided at both ends of the support tube 6. Three-jaw chucks 7 are fixedly installed on the outer edges at both ends of the support tube 6 respectively. The support tube 6 can be coaxial with the rotating shaft 3. A sliding rod 8 is slidably connected to the sliding seat 2. One end of the sliding rod 8 is detachably connected with a connecting rod 9 through a pin. The bottom of the connecting rod 9 is rotatably connected with a positioning assembly 10 coaxial with the rotating shaft 3. By clamping the graphite round bar to be drilled by the two three-jaw chucks 7, by installing the positioning assembly 10, by moving the support 5 up and down, the positioning assembly 10 can be made to contact one end of the graphite round bar, and according to the position where holes need to be drilled in the graphite round bar, the height of the support 5 is adjusted, and pre-alignment is performed by punctuating the graphite round bar through the positioning assembly 10. And because the support tube 6 can rotate, it is thus convenient to drill multiple holes in the graphite round bar according to requirements without disassembling the graphite round bar, making the device convenient to adjust the position of the graphite round bar to be processed, thus convenient to adjust the drilling position of the graphite round bar, and convenient to perform pre-alignment adjustment on the drilling position of the graphite round bar.

[0018] In an embodiment of the present application, preferably, the positioning assembly 10 includes a cross shaft 101 and a positioning cone 102. The cross shaft 101 is rotatably connected to the bottom of the connecting rod 9. One side of the positioning cone 102 is threadedly connected to the cross shaft 101. By rotating the positioning cone 102, the tip of the positioning cone 102 can be used to punctuate the graphite round bar.

[0019] In an embodiment of the present application, preferably, a rotatable screw rod 11 is provided on the frame 1. The sliding seat 2 is threadedly connected to the screw rod 11. By rotating the screw rod 11, the sliding seat 2 can be made to drive the drill bit 4 to slide on the frame 1.

[0020] In an embodiment of the present application, preferably, a motor 12 is fixedly installed on one side of the sliding seat 2. The output end of the motor 12 is fixedly connected to the rotating shaft 3. By starting the motor 12, the rotating shaft 3 can be driven to rotate, thereby driving the drill bit 4 to rotate.

[0021] In an embodiment of the present application, preferably, limiting columns 13 are respectively slidably connected at the four corners of the support 5. The bottoms of the plurality of limiting columns 13 are fixedly connected to the frame 1. A cross beam 14 is provided above the support 5. The cross beam 14 is fixedly connected to the frame 1. A knob 15 is threadedly connected to the cross beam 14. The bottom of the knob 15 is rotatably connected to the support 5, so that the support 5 can only move up and down, and by rotating the knob 15, the height position of the support 5 can be adjusted.

[0022] In an embodiment of the present application, preferably, a plurality of jacks 16 arranged in an annular array are provided on one side of the support 5. A plurality of insertion blocks 17 corresponding to the jacks 16 one by one are fixed at the outer edge of one end of the support tube 6. The plurality of insertion blocks 17 can be respectively inserted into the corresponding jacks 16. The outer edge of the other end of the support tube 6 is connected to the support 5 through a spring. The support tube 6 can slide left and right on the support 5. The plurality of insertion blocks 17 can be inserted into the corresponding jacks 16 under the action of the spring. When it is necessary to rotate the support tube 6, by pushing one end of the support tube 6, the spring is compressed. After rotating the support tube 6 to an appropriate angle, the support tube 6 is released, so that the insertion blocks 17 can be inserted into the corresponding jacks 16 under the action of the spring, thereby playing a role in fixing the position after rotation.

[0023] When the present utility model is in use, the graphite round bar to be drilled is clamped by two three-jaw chucks 7, the positioning assembly 10 is installed, and the knob 15 is rotated to adjust the height position of the support 5. By moving the support 5 up and down and moving the sliding seat 2, the positioning assembly 10 can be brought into contact with the graphite round bar at one end. According to the position where holes need to be drilled in the graphite round bar, the height of the support 5 is adjusted, and the positioning assembly 10 is used to mark points on the graphite round bar for pre-alignment. The support tube 6 can slide left and right on the support 5. The plurality of insertion blocks 17 can be inserted into the corresponding jacks 16 under the action of the spring. When it is necessary to rotate the support tube 6, by pushing one end of the support tube 6, the spring is compressed. After rotating the support tube 6 to an appropriate angle, the support tube 6 is released, so that the insertion blocks 17 can be inserted into the corresponding jacks 16 under the action of the spring, thereby playing a role in fixing the position after rotation. And because the support tube 6 can rotate, it is convenient to drill a plurality of holes in the graphite round bar according to requirements without disassembling the graphite round bar. When using the drill bit 4 to drill, the pin needs to be pulled out in advance and the connecting rod 9 needs to be disassembled to avoid affecting the use of the drill bit 4.
