Description

Technical Field

[0001] This utility model relates to the field of graphite rod processing technology, specifically to a deep hole processing device for graphite rods. Background Technology

[0002] Graphite rods are rod-shaped products made from graphite as raw material. Due to their unique physical and chemical properties, they have a wide range of applications in many fields.

[0003] When machining graphite rods, it is sometimes necessary to drill deep holes axially. However, currently, the graphite rod is usually fixed, and drilling is performed by rotating a drill bit and its extension rod. Due to the considerable length of the extension rod, the drill bit requires significant movement during drilling, which can easily cause the graphite rod to deviate during drilling. Therefore, there is an urgent need to design a deep hole machining device for graphite rods to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a deep hole machining device for graphite rods to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A graphite rod deep hole machining device includes a base, a second column fixed to the top of the base, a rotating mechanism on the top of the second column, a graphite rod body fixed inside the rotating mechanism, the rotating mechanism being located in the middle of the graphite rod body, an extension rod on one side of the graphite rod body, a drill bit fixed to one end of the extension rod near the graphite rod body, and a feed mechanism fixed to the bottom of the extension rod.

[0007] Furthermore, the feeding mechanism includes a mounting base that slides on the top of the base, a column is fixed to the top outer wall of the mounting base, and one end of the extension rod is fixed to the column.

[0008] Furthermore, a sliding groove is formed on one side of the outer wall of the base, and a slider is slidably connected inside the sliding groove. The mounting base is fixed to the slider, and a screw is connected to the bearing inside the sliding groove. The screw is threadedly connected to the slider. A motor is fixed on one side of the outer wall of the base, and the output shaft of the motor is keyed to the screw.

[0009] Furthermore, the rotating mechanism includes a mounting shell fixed to the top of the second column, a rotating cylinder connected to the internal bearing of the mounting shell, the graphite rod body inserted into the inside of the rotating cylinder, a worm gear fixed to the outside of the rotating cylinder, a worm connected to the internal bearing of the mounting shell, the worm meshing with the worm gear, a second motor fixed to the top outer wall of the mounting shell, and the output shaft of the second motor keyed to the worm.

[0010] Furthermore, the rotating cylinder has a conical surface inside, and a conical ring that matches the conical surface is sleeved on the outside of the graphite rod body. The outer wall of the conical ring has centrally symmetrically distributed contraction gaps. The end of the rotating cylinder is threaded with a pressure cap, and the graphite rod body is inserted into the inside of the pressure cap.

[0011] Furthermore, a guide sleeve is fitted onto the outside of the extension rod, and a support rod is fixed between the guide sleeve and the base.

[0012] In the above technical solution, the graphite rod deep hole processing device provided by this utility model has the following advantages: the rotating mechanism drives the graphite rod body to rotate in the middle, thereby making it less likely for the drill bit to move excessively when performing deep hole processing on the graphite rod body, effectively preventing the drilling from going off-center and improving the processing quality of the graphite rod body; the pressure cap is threadedly connected to the rotating cylinder, so that the conical ring can press and fix the graphite rod body when it is compressed by pressure, and at the same time, it can achieve the effect of automatic centering when fixing the graphite rod body, making the graphite rod body more stable when rotating.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown in the figure, the graphite rod deep hole processing device provided by this utility model includes a base 1, a column 2 12 fixed on the top of the base 1, a rotating mechanism 13 provided on the top of the column 2 12, a graphite rod body 14 fixed inside the rotating mechanism 13, the rotating mechanism 13 being located in the middle of the graphite rod body 14, an extension rod 8 provided on one side of the graphite rod body 14, a drill bit 9 fixed at one end of the extension rod 8 near the graphite rod body 14, and a feed mechanism fixed at the bottom of the extension rod 8.

[0021] Specifically, in this embodiment, a base 1 is included, and a second column 12 is fixed to the top of the base 1. A rotating mechanism 13 is provided on the top of the second column 12. A graphite rod body 14 is fixed inside the rotating mechanism 13. The rotating mechanism 13 can drive the graphite rod body 14 to rotate. The rotating mechanism 13 is located in the middle of the graphite rod body 14. The rotating mechanism 13 drives the graphite rod body 14 to rotate from the middle, which is more stable than driving it to rotate from the end. An extension rod 8 is provided on one side of the graphite rod body 14. A drill bit 9 is fixed to one end of the extension rod 8 near the graphite rod body 14. The end of the drill bit 9 corresponds to the center of the graphite rod body 14, so that the drill bit 9 can drill a deep hole in the axial direction of the graphite rod body 14. When in use, the graphite rod body 14 rotates, but the drill bit 9 does not rotate. A feeding mechanism is fixed to the bottom of the extension rod 8. The feeding mechanism is used for the feeding movement of the drill bit 9.

[0022] The present invention provides a graphite rod deep hole machining device, which drives the graphite rod body 14 to rotate in the middle of the rotating mechanism 13, so that when the drill bit 9 performs deep hole machining on the graphite rod body 14, the drill bit 9 is less likely to move too much, which can effectively prevent the drilling from going off-center and improve the machining quality of the graphite rod body 14.

[0023] In another embodiment of this utility model, the feeding mechanism includes a mounting seat 5 that slides on the top of the base 1, a column 7 fixed to the top outer wall of the mounting seat 5, and one end of the extension rod 8 fixed to the column 7; a sliding groove 2 is opened on one side outer wall of the base 1, and a slider 4 is slidably connected inside the sliding groove 2, the mounting seat 5 is fixed to the slider 4, a screw 3 is connected to the bearing inside the sliding groove 2, the screw 3 is threadedly connected to the slider 4, and the slider 4 is driven to move when the screw 3 rotates; a motor 6 is fixed on one side outer wall of the base 1, and the output shaft of the motor 6 is keyed to the screw 3, and the motor 6 drives the screw 3 to rotate.

[0024] In another embodiment of this utility model, the rotating mechanism 13 includes a mounting shell 15 fixed to the top of the column 12. A rotating cylinder 16 is connected to the internal bearing of the mounting shell 15. A graphite rod body 14 is inserted into the inside of the rotating cylinder 16. A worm wheel 19 is fixed to the outside of the rotating cylinder 16. A worm 18 is connected to the internal bearing of the mounting shell 15. The worm 18 meshes with the worm wheel 19. When the worm 18 rotates, it drives the worm wheel 19 and the rotating cylinder 16 to rotate. A motor 17 is fixed to the top outer wall of the mounting shell 15. The output shaft of the motor 17 is keyed to the worm 18. The motor 17 drives the worm 18 to rotate.

[0025] In another embodiment of this utility model, the rotating cylinder 16 has a conical surface 22 inside, and a conical ring 21 adapted to the conical surface 22 is sleeved on the outside of the graphite rod body 14. The outer wall of the conical ring 21 has centrally symmetrically distributed contraction gaps 23. When the conical ring 21 is compressed towards the conical surface 22 under force, the conical ring 21 can contract, thereby clamping and fixing the graphite rod body 14, and making the axis of the graphite rod body 14... The axis of the rotating cylinder 16 is coincident. The end of the rotating cylinder 16 is threadedly connected to a pressure cover 20. The graphite rod body 14 is inserted into the inside of the pressure cover 20. When the pressure cover 20 and the rotating cylinder 16 are bolted together, the pressure cover 20 compresses the conical ring 21. The extension rod 8 is sleeved with a guide sleeve 10. A support rod 11 is fixed between the guide sleeve 10 and the base 1. The guide sleeve 10 supports the extension rod 8 and makes the extension rod 8 more stable during the feed motion.

[0026] Working principle: In use, the graphite rod body 14 to be drilled is inserted into the inside of the rotating cylinder 16, with the rotating cylinder 16 located in the middle of the graphite rod body 14. The conical ring 21 and the clamping cover 20 are fitted onto the graphite rod body 14, with the conical ring 21 located inside the conical surface 22. Then, the clamping cover 20 is threadedly connected to the rotating cylinder 16, so that the clamping cover 20 squeezes the conical ring 21, causing the conical ring 21 to contract through the contraction gap 23, thus fixing the graphite rod body 14. Then, the motor 217 drives the worm gear 18 to rotate, which in turn drives the worm wheel 19 and the rotating cylinder 16 to rotate. The rotation of the rotating cylinder 16 causes the graphite rod body 14 to rotate. Then, the motor drives the screw 3 to rotate, which causes the screw 3 to move the slider 4 and the column 17 closer to the column 212, and the drill bit 9 drills axially into the graphite rod body 14.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
