Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-6 A laser repair device for the aperture of a tungsten steel wire drawing die includes a vertical support column 1, a wire drawing die at the top of the vertical support column 1, an L-shaped mounting plate 2 fixed at one end of the vertical support column 1, a laser cladding machine 7 fixed on the inner side of the top of the L-shaped mounting plate 2, a transverse sliding plate 6 at the top of the L-shaped mounting plate 2, a transverse connecting pipe 8 rotatably connected inside the transverse sliding plate 6, the laser cladding machine 7 and the transverse connecting pipe 8 being connected through a material conveying pipe, a cladding laser head 9 at the end of the transverse connecting pipe 8 away from the laser cladding machine 7, and a grinding mechanism at the outer side of the transverse connecting pipe 8.
[0024] One end of the L-shaped mounting plate 2 is bolted with a first drive motor 3. The output end of the first drive motor 3 is fixed with a transverse threaded rod 4. The transverse threaded rod 4 passes through the interior of the transverse sliding plate 6 and is threadedly connected to the transverse sliding plate 6. A transverse light rod 5 is slidably connected inside the transverse sliding plate 6. The transverse light rod 5 is close to one end of the L-shaped mounting plate 2 and is fixedly connected to the L-shaped mounting plate 2. Through the operation of the first drive motor 3, the transverse threaded rod 4 can rotate. The rotation of the transverse threaded rod 4 causes the transverse sliding plate 6 to move laterally outside the transverse light rod 5, thereby enabling the cladding laser head 9 to move laterally and move into the interior of the wire drawing die.
[0025] The transverse sliding plate 6 has a circular through hole inside. The transverse optical rod 5 is located inside the circular through hole and is slidably connected to the transverse sliding plate 6 through the circular through hole. The circular through hole allows the transverse sliding plate 6 to move laterally outside the transverse threaded rod 4. The movement of the transverse sliding plate 6 causes the cladding laser head 9 to move.
[0026] A second drive motor 10 is bolted to one end of the top of the transverse sliding plate 6. A drive gear 11 is fixed to the output end of the second drive motor 10. A driven gear 12 is meshed with the top of the drive gear 11. The driven gear 12 is sleeved on the outside of the transverse connecting tube 8 and fixedly connected to the transverse connecting tube 8. Both the drive gear 11 and the driven gear 12 are located inside the transverse sliding plate 6 and are rotatably connected to the transverse sliding plate 6. Through the operation of the second drive motor 10, the drive gear 11 is rotated. The rotation of the drive gear 11 causes the driven gear 12 to rotate. The rotation of the driven gear 12 causes the transverse connecting tube 8 to rotate inside the transverse sliding plate 6. The rotation of the transverse connecting tube 8 causes the cladding laser head 9 to rotate.
[0027] The grinding mechanism includes a horizontal hydraulic cylinder 13, the top of which is fixedly connected to a horizontal connecting pipe 8. A horizontal sliding ring 14 is fixedly attached to the output end of the horizontal hydraulic cylinder 13. The horizontal sliding ring 14 is located outside the horizontal connecting pipe 8 and is slidably connected to the horizontal connecting pipe 8. An inclined rotating column 15 is rotatably connected to the top of the horizontal sliding ring 14. A vertical sliding pipe 17 is rotatably connected to one end of the inclined rotating column 15. A vertical support rod 16 is slidably connected inside the vertical sliding pipe 17. The bottom of the vertical support rod 16 is fixedly connected to the horizontal connecting pipe 8. A U-shaped mounting bracket 18 is fixedly attached to the top of the vertical sliding pipe 17. A third drive motor 19 is bolted to one end of the U-shaped mounting bracket 18. A circular grinding roller 20 is provided inside the U-shaped mounting bracket 18. The output end of the third drive motor 19 is fixedly connected to the circular grinding roller 20.
[0028] The vertical sliding tube 17 has a circular through hole inside. The vertical support rod 16 is located inside the circular through hole and is slidably connected to the vertical sliding tube 17 through the circular through hole. The circular through hole allows the vertical sliding tube 17 to slide vertically on the outside of the vertical support rod 16, thereby allowing the position and height of the circular grinding roller 20 to be adjusted.
[0029] A rectangular slider is fixed at the bottom of the transverse connecting pipe 8, and a rectangular groove is provided inside the transverse sliding ring 14. The transverse sliding ring 14 and the transverse connecting pipe 8 are slidably connected by the cooperation of the rectangular slider and the rectangular groove. By setting the rectangular slider and the rectangular groove, the transverse sliding ring 14 can move laterally on the outside of the transverse connecting pipe 8, thereby guiding the sliding trajectory of the transverse sliding ring 14 on the outside of the transverse connecting pipe 8.
[0030] The output end of the third drive motor 19 passes through the interior of the U-shaped mounting bracket 18 and is rotatably connected to the U-shaped mounting bracket 18 through a bearing, so that the third drive motor 19 can pass through the interior of the U-shaped mounting bracket 18 and rotate inside the U-shaped mounting bracket 18, thereby enabling the operation of the third drive motor 19 to drive the circular grinding roller 20 to rotate inside the U-shaped mounting bracket 18.
[0031] Here, the operation of the transverse hydraulic cylinder 13 causes the transverse sliding ring 14 to move outside the transverse connecting pipe 8. The movement of the transverse sliding ring 14 causes the vertical sliding pipe 17 to slide vertically outside the vertical support rod 16. The movement of the vertical sliding pipe 17 causes the U-shaped mounting bracket 18 to move. The movement of the U-shaped mounting bracket 18 causes the circular grinding roller 20 to move. The operation of the third drive motor 19 causes the circular grinding roller 20 to rotate, thereby enabling the circular grinding roller 20 to grind the diameter of the hole inside the wire drawing die.
[0032] Working principle: The operation of the first drive motor 3 enables the transverse threaded rod 4 to rotate. The rotation of the transverse threaded rod 4 enables the transverse sliding plate 6 to move laterally outside the transverse light rod 5. The lateral movement of the transverse sliding plate 6 enables the transverse connecting tube 8 and the cladding laser head 9 to move toward the inner diameter of the wire drawing die. Through the operation of the second drive motor 10 and the laser cladding machine 7, the drive gear 11 and the driven gear 12 are enabled to rotate. The rotation of the driven gear 12 enables the transverse connecting tube 8 to rotate inside the transverse sliding plate 6, thereby enabling the cladding laser head 9 to rotate within the inner diameter of the wire drawing die, so that the cladding laser head 9 can repair the inner diameter of the wire drawing die.
[0033] The continuous movement of the transverse sliding plate 6 allows the circular grinding roller 20 to grind the wire drawing die at the junction. The operation of the transverse hydraulic cylinder 13 allows the transverse sliding ring 14 to move outside the transverse connecting pipe 8. The movement of the transverse sliding ring 14 causes the vertical sliding pipe 17 to slide vertically outside the vertical support rod 16. The movement of the vertical sliding pipe 17 causes the U-shaped mounting bracket 18 to move. The movement of the U-shaped mounting bracket 18 causes the circular grinding roller 20 to move. The operation of the third drive motor 19 causes the circular grinding roller 20 to rotate, thereby enabling the circular grinding roller 20 to grind the internal aperture of the wire drawing die. Through the operation of the transverse connecting pipe 8, the circular grinding roller 20 can better grind the inside of the wire drawing die.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
