Description

Technical Field

[0001] This invention relates to the field of graphite rod processing, specifically to a graphite pad device for graphite rod slicing. Background Technology

[0002] Graphite gaskets are formed by cutting graphite rods into graphite sheets and then stamping the graphite sheets. The current production of graphite gaskets usually involves manually pushing the graphite rods towards the cutting tool, then using the cutting tool to slice the graphite rods, and then transporting the graphite sheets to the stamping table, where a ring-shaped cutting tool is used to stamp the graphite sheets to form the final graphite gasket.

[0003] The existing technology has at least the following problems that have not been solved: When the existing graphite rods are processed into slices, the graphite rods need to be pushed toward the slicing mechanism at equal intervals. The graphite rods need to be clamped by a clamping device before they are moved. The clamping of the graphite rods by the clamping device will cause wear on its outer wall. Furthermore, the outer wall of the graphite rods will also be worn during the transfer process. Therefore, the outer wall of the graphite rods needs to be polished before the graphite rods are processed into slices to avoid the graphite rods being too thin after slicing, which would make them difficult to polish.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] In this invention, burrs and protrusions may be generated during the production process of graphite rods, resulting in uneven outer walls or rough surfaces. By polishing to remove surface defects, the outer walls of the graphite rods can achieve high-precision roundness, ensuring that the blades are fed smoothly along the axis during slicing and that the thickness is uniform.

[0016] In this invention, the clamping mechanism controlled by the switching mechanism first serves to clamp, move, and limit the graphite rod. Then, by rotating the friction plate inside the clamping mechanism around the graphite rod, the graphite rod can be polished, thereby improving the processing accuracy of the graphite rod.

[0017] In this invention, when the moving frame moves, it drives the rotating cylinder to rotate around the outer wall of the graphite rod while simultaneously grinding it along the axis of the graphite rod over a short distance. Through the grinding process of circumferential rotation and axial feed, the graphite rod's outer wall is uniformly processed in the entire circumference, allowing the graphite rod to cover a larger processing area in a short time during the processing.

[0018] In this invention, the locking rod is clamped to the outer wall of the graphite rod by the locking plate, and the moving electric cylinder drives the fixing plate to simultaneously position and clamp the graphite rod, thereby limiting the position of the graphite rod when it is being ground by the rotating cylinder, thus preventing the position of the graphite rod from shifting and affecting the processing accuracy of the graphite rod.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 12 The present invention provides a technical solution: a graphite pad device for graphite rod slicing, including a processing table 1, a slicing mechanism 7 is provided on the top of the processing table 1, a support frame 11 is fixedly connected to the inner wall of the processing table 1, a fixed rod 12 is fixedly connected to the support frame 11, and a movable frame 13 is slidably connected to the fixed rod 12.

[0034] The movable frame 13 is rotatably connected to a clamping mechanism 2 for moving graphite rods, and the clamping mechanism 2 is oriented toward the slicing mechanism 7. The movable frame 13 is provided with a lead screw slide 4, which is connected to the clamping mechanism 2. The lead screw slide 4 is provided with a switching mechanism 5. The top of the support frame 11 is slidably connected to a moving mechanism 6, which is fixedly connected to the movable frame 13 and can move the clamped graphite rods at equal intervals. The moving mechanism 6 is in contact with the switching mechanism 5 on the lead screw slide 4.

[0035] In this embodiment, the clamping mechanism 2 includes a rotating cylinder 21 rotatably connected to the end face of the moving frame 13 facing the slicing mechanism 7. A plurality of mounting frames 22 are arranged around the inner wall of the rotating cylinder 21. Each mounting frame 22 is provided with a sliding groove 23. A sliding rod 24 is slidably connected in the sliding groove 23. A clamping block 25 is fixedly connected to the sliding rod 24. A compression spring 26 is connected between the side wall of the clamping block 25 and the inner wall of the mounting frame 22. A friction plate 27 is provided on the side of the clamping block 25 facing the graphite rod.

[0036] A conical cylinder 28 is slidably connected to the movable frame 13 toward the rotating cylinder 21. The conical cylinder 28 is connected to the slide 44 of the lead screw slide 4. Each clamping block 25 is inlaid with a ball 29 that abuts against the inner wall of the conical cylinder 28. A drive motor 3 is fixedly connected to the movable frame 13. The main shaft of the drive motor 3 is driven by a gear set 31. The gear set 31 includes a drive gear 32 and a transmission gear 33. The drive gear 32 is driven by the main shaft of the drive motor 3, and the transmission gear 33 is driven by the lead screw slide 4. The drive gear 32 and the transmission gear 33 mesh with each other.

[0037] The graphite rod is located inside the rotating cylinder 21. The drive motor 3 rotates the gear set 31, which drives the slide 44 of the lead screw slide 4 to move toward the rotating cylinder 21. The cone 28 connected to the slide 44 extends toward the rotating cylinder 21. Under the action of the inclined surface of the inner wall of the cone 28, the ball 29 can drive the clamping block 25 to move toward the graphite rod inside the rotating cylinder 21. The friction plate 27 on the clamping block 25 is in close contact with the outer wall of the graphite rod to clamp and limit the graphite rod.

[0038] In this embodiment, the lead screw slide 4 includes a positioning rod 41 that is fixedly connected to the movable frame 13, a lead screw 42 is provided between the two positioning rods 41, and the lead screw 42 is rotatably connected to the movable frame 13. The transmission gear 33 is fixedly connected to the lead screw 42, and the slide 44 is slidably connected to the two positioning rods 41. An inner nut 43 that is helically connected to the lead screw 42 is rotatably connected inside the slide 44.

[0039] The switching mechanism 5 includes a limiting block 51 slidably connected to the slide table 44. The inner nut 43 has a limiting groove 52 that engages with the limiting block 51. A connecting rod 53 is fixedly connected to the limiting block 51. A sliding block 54 is also slidably connected to the slide table 44. The sliding block 54 has an inclined groove 55 that slidably engages with the connecting rod 53. A connecting spring 56 is provided between the side wall of the sliding block 54 and the inner wall of the slide table 44. The end of the sliding block 54 is inclined toward the rotating cylinder 21. A gear ring 57 is provided on the inner wall of the rotating cylinder 21. A rotating gear 58 that meshes with the gear ring 57 is rotatably connected to the moving frame 13. The rotating gear 58 is slidably connected to the spline of the outer wall of the inner nut 43.

[0040] The drive motor 3 drives the lead screw 42 to rotate through the gear set 31. The limiting block 51 on the slide table 44 engages with the limiting groove 52 on the inner nut 43 to limit the inner nut 43. When the lead screw 42 rotates, the inner nut 43 is limited by the limiting block 51, causing the inner nut 43 to drive the slide table 44 to move toward the rotating cylinder 21. At this time, the inner wall of the cone cylinder 28 can drive the clamping block 25 to clamp the graphite rod.

[0041] When the inclined end of the sliding block 54 is squeezed, the sliding block 54 will slide on the slide table 44. When the slide table 44 moves, it drives the connecting rod 53 to move through the inclined groove 55, so that the connecting rod 53 drives the limiting pressure block 51 to move upward and separate from the limiting groove 52 on the inner nut 43. When the inner nut 43 is no longer restricted by the limiting pressure block 51, the inner nut 43 will rotate synchronously with the lead screw 42. Since the inner nut 43 and the rotating gear 58 are connected by a spline sliding connection, the rotating gear 58 will rotate and cause the gear ring 57 to rotate. The rotation of the gear ring 57 drives the rotating cylinder 21 to rotate. The graphite rod is located inside the rotating cylinder 21, and the friction plate 27 on the clamping block 25 contacts the outer wall of the graphite rod. When the rotating cylinder 21 rotates, the friction plate 27 can rotate around the graphite rod to polish the outer wall of the graphite rod.

[0042] During the production process, graphite rods may produce burrs, protrusions, etc., which may result in uneven outer walls or rough surfaces. By grinding, surface defects are removed, so that the outer wall of the graphite rod can achieve high-precision roundness, ensuring that the blade feeds smoothly along the axis and the thickness is uniform during slicing.

[0043] The switching mechanism 5 controls the clamping mechanism 2 to clamp the graphite rod, which firstly moves and limits the graphite rod. Then, the friction plate 27 set in the clamping mechanism 2 rotates around the graphite rod, which can polish the graphite rod and improve the processing accuracy of the graphite rod.

[0044] In this embodiment, the moving mechanism 6 includes a push cylinder 61 fixedly connected to the top of the support frame 11. The telescopic end of the push cylinder 61 is fixedly connected to a push plate 62. The push plate 62 is fixedly connected to the moving frame 13. The side wall of the push plate 62 is also provided with a first moving groove 63 that is inclined. The side wall of the support frame 11 is provided with a second moving groove 64 that is L-shaped. A moving rod 65 is inserted between the first moving groove 63 and the second moving groove 64. The moving rod 65 is provided with a moving wheel 66 located in the first moving groove 63 and the second moving groove 64.

[0045] A wedge-shaped pressure plate 67 is fixedly connected to the moving rod 65. A pressure rod 68 is provided on the support frame 11 above the rotating cylinder 21. A pressure roller 69 is provided at the top of the pressure rod 68 and abuts against the pressure plate 67. A return spring 610 is sleeved on the pressure rod 68, and the two ends of the return spring 610 are respectively connected to the pressure rod 68 and the support frame 11. The bottom of the pressure rod 68 abuts against the inclined end of the sliding block 54.

[0046] The lead screw slide 4 first controls the clamping mechanism 2 to clamp the graphite rod. Driven by the push cylinder 61, the push plate 62 moves toward the slicing mechanism 7. At this time, the first moving groove 63 on the push plate 62 and the second moving groove 64 on the support frame 11 will drive the moving rod 65 to move toward the pressure rod 68. When the graphite rod is below the slicing mechanism 7, the pressure plate 67 on the moving rod 65 contacts the pressure rod 68, causing the pressure rod 68 to move down. At this time, the pressure rod 68 is above the sliding block 54, and the bottom of the pressure rod 68 contacts the end of the sliding block 54, causing the sliding block 54 to move on the slide 44, releasing the restriction on the inner nut 43. At this time, the lead screw 42 rotates, which can drive the rotating cylinder 21 to rotate around the graphite rod to process the graphite rod.

[0047] At this time, when the electric cylinder 61 drives the push plate 62 to continue moving, the moving frame 13 will drive the rotating cylinder 21 to move along the axis of the graphite rod, and the moving rod 65 will move downward under the restriction of the first moving groove 63 and the second moving groove 64. The pressure rod 68 continues to move downward and continues to abut against the sliding block 54. The moving frame 13 moves along the axis of the graphite rod. When the sliding block 54 abuts against the pressure rod 68, it continues to contract under the drive of the connecting spring 56 and will not cause movement obstruction to the moving frame 13. At this time, when the moving frame 13 moves, it will drive the rotating cylinder 21 to rotate around the outer wall of the graphite rod and grind it along the axis of the graphite rod in a short distance. Through the grinding process of circumferential rotation plus axial feed, the outer wall of the graphite rod is uniformly processed in the entire circumference, so that the graphite rod covers a larger processing area in a short time during the processing.

[0048] In this embodiment, the bottom of the support frame 11 is fixedly connected to a support bracket 611 facing the movable frame 13. A telescopic locking rod 612 is slidably connected to the support bracket 611. An arc-shaped locking plate 613 is fixedly connected to one end of the locking rod 612 facing the outer wall of the graphite rod. A protrusion 614 is provided at the other end of the locking rod 612 away from the outer wall of the graphite rod. An inclined side plate 615 with the protrusion 614 abutting is provided on the inner wall of the movable frame 13. A corresponding movable electric cylinder 616 is fixedly connected to the inner wall of the support frame 11. A fixed plate 617 is provided at the telescopic end of the movable electric cylinder 616 facing the graphite rod.

[0049] When the pusher cylinder 61 drives the pusher plate 62 to move the moving frame 13 toward the slicing mechanism 7, the pressure rod 68 abuts against the side wall of the sliding frame, causing the inner nut 43 to be released from its limit. At the same time, the inclined side plate 615 on the inner wall of the moving frame 13 gradually squeezes the protrusion 614, causing the locking rod 612 to be clamped toward the outer wall of the graphite rod by the locking plate 613. Meanwhile, the moving cylinder 616 drives the fixing plate 617 to simultaneously position and clamp the graphite rod, thereby limiting the graphite rod. When the graphite rod is ground under the drive of the rotating cylinder 21, the graphite rod is limited, preventing the position of the graphite rod from shifting and affecting the processing accuracy of the graphite rod.

[0050] In this embodiment, the slicing mechanism 7 includes a stamping table 71 fixedly mounted on the top of the processing table 1. An adjusting plate 72 is slidably connected to the stamping table 71. A slicing blade 73 for slicing graphite rods is mounted on the adjusting plate 72. The slicing blade 73 is controlled by a CNC system.

[0051] The graphite rod is sliced ​​by the slicing blade 73. After slicing, the electric cylinder 61 drives the push plate 62 to move and reset. The inclined side plate 615 on the moving frame 13 separates from the outer wall of the graphite rod. At the same time, the pressure rod 68 moves upward and resets under the action of the reset spring 610. The sliding block 54, driven by the connecting spring 56, causes the inclined groove 55 on the sliding block 54 to drive the connecting rod 53 to align the limiting pressure block 51 with the limiting groove 52 on the inner nut 43. At this time, the drive motor 3 drives the lead screw 42 to rotate in the opposite direction, so that the clamping block 25 moves away from the graphite rod to prevent the moving frame 13 from scratching the outer wall of the graphite rod during the resetting process. After the moving frame 13 resets and moves, the graphite rod is clamped again by the clamping mechanism 2, which can move the graphite rod at equal intervals to ensure that the thickness of the slices processed each time is consistent.

[0052] The method of use and advantages of this invention: The method of using the graphite pad device in the graphite rod slice is as follows:

[0053] like Figures 1 to 12As shown: The graphite rod is located inside the rotating cylinder 21. The drive motor 3 rotates the gear set 31, which drives the slide 44 of the lead screw slide 4 to move toward the rotating cylinder 21. The cone 28 connected to the slide 44 extends toward the rotating cylinder 21. Under the action of the inclined surface of the inner wall of the cone 28, the ball 29 can drive the clamping block 25 to move toward the graphite rod inside the rotating cylinder 21. The friction plate 27 on the clamping block 25 is in close contact with the outer wall of the graphite rod to clamp and limit the graphite rod.

[0054] The drive motor 3 drives the lead screw 42 to rotate through the gear set 31. The limiting block 51 on the slide table 44 engages with the limiting groove 52 on the inner nut 43 to limit the inner nut 43. When the lead screw 42 rotates, the inner nut 43 is limited by the limiting block 51, causing the inner nut 43 to drive the slide table 44 to move toward the rotating cylinder 21. At this time, the inner wall of the cone cylinder 28 can drive the clamping block 25 to clamp the graphite rod.

[0055] When the inclined end of the sliding block 54 is squeezed, the sliding block 54 will slide on the slide table 44. When the slide table 44 moves, it drives the connecting rod 53 to move through the inclined groove 55, so that the connecting rod 53 drives the limiting pressure block 51 to move upward and separate from the limiting groove 52 on the inner nut 43. When the inner nut 43 is no longer restricted by the limiting pressure block 51, the inner nut 43 will rotate synchronously with the lead screw 42. Since the inner nut 43 and the rotating gear 58 are connected by a spline sliding connection, the rotating gear 58 will rotate and cause the gear ring 57 to rotate. The rotation of the gear ring 57 drives the rotating cylinder 21 to rotate. The graphite rod is located inside the rotating cylinder 21, and the friction plate 27 on the clamping block 25 contacts the outer wall of the graphite rod. When the rotating cylinder 21 rotates, the friction plate 27 can rotate around the graphite rod to polish the outer wall of the graphite rod.

[0056] The lead screw slide 4 first controls the clamping mechanism 2 to clamp the graphite rod. Driven by the push cylinder 61, the push plate 62 moves toward the slicing mechanism 7. At this time, the first moving groove 63 on the push plate 62 and the second moving groove 64 on the support frame 11 will drive the moving rod 65 to move toward the pressure rod 68. When the graphite rod is below the slicing mechanism 7, the pressure plate 67 on the moving rod 65 contacts the pressure rod 68, causing the pressure rod 68 to move down. At this time, the pressure rod 68 is above the sliding block 54, and the bottom of the pressure rod 68 contacts the end of the sliding block 54, causing the sliding block 54 to move on the slide 44, releasing the restriction on the inner nut 43. At this time, the lead screw 42 rotates, which can drive the rotating cylinder 21 to rotate around the graphite rod to process the graphite rod.

[0057] At this time, when the electric cylinder 61 drives the push plate 62 to continue moving, the moving frame 13 will drive the rotating cylinder 21 to move along the axis of the graphite rod, and the moving rod 65 will move downward under the restriction of the first moving groove 63 and the second moving groove 64. The pressure rod 68 continues to move downward and continues to abut against the sliding block 54. The moving frame 13 moves along the axis of the graphite rod. When the sliding block 54 abuts against the pressure rod 68, it continues to contract under the drive of the connecting spring 56 and will not cause movement obstruction to the moving frame 13. At this time, when the moving frame 13 moves, it will drive the rotating cylinder 21 to rotate around the outer wall of the graphite rod and grind it along the axis of the graphite rod in a short distance. Through the grinding process of circumferential rotation plus axial feed, the graphite rod outer wall is uniformly processed in the entire circumference, so that the graphite rod covers a larger processing area in a short time during the processing.

[0058] When the pusher cylinder 61 drives the pusher plate 62 to move the moving frame 13 toward the slicing mechanism 7, the pressure rod 68 abuts against the side wall of the sliding frame, causing the inner nut 43 to be released from its limit. At the same time, the inclined side plate 615 on the inner wall of the moving frame 13 gradually squeezes the protrusion 614, causing the locking rod 612 to be clamped toward the outer wall of the graphite rod by the locking plate 613. Meanwhile, the moving cylinder 616 drives the fixing plate 617 to simultaneously position and clamp the graphite rod, thereby limiting the graphite rod. When the graphite rod is ground under the drive of the rotating cylinder 21, the graphite rod is limited, preventing the position of the graphite rod from shifting and affecting the processing accuracy of the graphite rod.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
