[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 The utility model provides a technical solution: an anti-vibration device for drilling rod processing, comprising a base frame mechanism 1, and an anti-vibration mechanism 2 is fixedly connected to the top of the base frame mechanism 1.

[0024] See also Figure 2 The chassis mechanism 1 includes a bottom plate 11, the top four sides of the bottom plate 11 are fixedly connected to the chute bins 12, the inner tops of the left and right chute bins 12 are fixedly connected to the connecting plates 13, the bottom of the connecting plates 13 are fixedly connected to the dual-axis motor 14, the left and right output ends of the dual-axis motor 14 extend to the inner sides of the left and right chute bins 12 and are fixedly connected to conical teeth 15, the outer walls of the two conical teeth 15 are engaged with the second conical teeth 16, and the inner walls of the two second conical teeth 16 are A rotating rod 17 is fixedly connected, and the front and rear ends of the two rotating rods 17 extend to the inner walls of the left and right chute bins 12 and are fixedly connected to the lifting rod transmission gear 18. The inner walls of the left and right chute bins 12 are slidably connected to the lifting rods 19. One side of the left and right lifting rods 19 is fixedly connected to a plurality of tooth blocks 110 and meshes with the outer wall of the lifting rod transmission gear 18. The tops of the left and right lifting rods 19 extend to the top of the outer wall of the chute bin 12 and are fixedly connected to the top plate 111.

[0025] When the drill rod needs to be processed, the drill rod is first inserted into the inner wall of the anti-vibration mechanism 2. When the height needs to be adjusted, the dual-axis motor 14 is first started. At this time, the left and right output ends of the dual-axis motor 14 begin to rotate, driving the conical teeth 15 to rotate accordingly. Due to the meshing relationship between the conical teeth 15 and the second conical teeth 16, the second conical teeth 16 also begin to rotate, thereby driving the rotation rod 17 and the lifting rod transmission gear 18 to rotate. The rotation of the lifting rod transmission gear 18 causes the meshing tooth block 110 to drive the lifting rod 19 to slide up and down the inner wall of the chute bin 12;

[0026] As the lifting rod 19 moves up and down, the top plate 111 fixed on its top will also move up and down accordingly. In this way, the top plate 111 can be adjusted to a suitable height according to processing requirements, ensuring that the drill rod is in the best position during the processing, improving processing accuracy and stability, making the entire lifting process smooth and reliable, avoiding vibration caused by improper height adjustment, and further improving processing quality.

[0027] See also Figure 3-5 The chassis mechanism 1 includes two anti-flutter fixed bins 21, the bottoms of the two anti-flutter fixed bins 21 are respectively fixedly connected to the left and right sides of the top of the top plate 111, the inner sides of the two anti-flutter fixed bins 21 are fixedly connected with a second motor connecting plate 22, the middle part of the top of the second motor connecting plate 22 is fixedly connected with a second dual-axis motor 23, and the left and right output ends of the second dual-axis motor 23 extend to the inner walls of the two anti-flutter fixed bins 21, the anti-flutter fixed bin 21 includes a disc bottom plate 211, the four sides of the top of the anti-flutter fixed bin 21 are respectively fixedly connected with connecting blocks 212, the tops of the left and right two groups of connecting blocks 212 are respectively fixedly connected with a connecting disk 213 and a second connecting disk 215, a connecting disk 213 is fixedly connected to a plurality of connecting rods 214 on a side close to the second connecting disk 215, and a plurality of connecting rods 214 are fixedly connected to a second connecting disk 215 on a side away from the connecting disk 213. A plurality of slide rods 216 are fixedly connected to a circular array on one side of the connecting disk 213. A gear 217 is rotatably connected to the side of the second connecting disk 215 close to the connecting disk 213. The gear 217 is fixedly connected to the output end of the second dual-axis motor 23 to one end of the inner wall of the anti-vibration fixed bin 21. The inner walls of the plurality of slide rods 216 are slidably connected to L-shaped slide rods 218. The sides of the plurality of L-shaped slide rods 218 away from the slide rods 216 are fixedly connected to a cylindrical slider 219. The second connecting disk 215 is rotatably connected to the inner side of the connecting disk 213 with a gear disk 2111. A plurality of arc grooves 2112 are formed in a circular array on one side of the gear disk 2111. The inner walls of the plurality of arc grooves 2112 are slidably connected to the outer wall of the cylindrical slider 219. The inner sides of the plurality of L-shaped slide rods 218 are fixedly connected to a plurality of running wheels 2110. The outer wall of the gear disk 2111 meshes with the outer wall of the gear 217.

[0028] When the drill rod needs to be processed, after the drill rod is inserted into the inner walls of the two anti-vibration fixed chambers 21, as the second dual-axis motor 23 is started, the output ends on the left and right sides respectively drive the gears 217 in the two anti-vibration fixed chambers 21 to rotate, and the gears 217 engage with the outer wall of the gear plate 2111, so that the gear plate 2111 rotates between the connecting plate 213 and the second connecting plate 215;

[0029] This rotational movement drives the movement of multiple arcuate grooves 2112 fixed to one side of the gear plate 2111. Since the arcuate grooves 2112 are slidably connected to the outer wall of the cylindrical slider 219, as the gear plate 2111 rotates, the cylindrical slider 219 moves along the trajectory of the arcuate grooves 2112. This design not only ensures the smooth movement of the cylindrical slider 219, but also achieves precise control of the movement trajectory of the cylindrical slider 219 through the guidance of the arcuate grooves.

[0030] At the same time, the movement of the cylindrical slider 219 drives the L-shaped slide bar 218 fixed thereto to slide in the inner wall of the slide rod 216. A plurality of runners 2110 are fixed to the inner side of the L-shaped slide bar 218. During the movement of the L-shaped slide bar 218, these runners fit into the outer wall of the drill rod fixed to the inner wall of the anti-vibration fixing chamber 21, thereby helping to stabilize the position of the drill rod and reduce vibration during the processing.

[0031] In addition, the connecting plate 213 and the second connecting plate 215 are fixedly connected via a plurality of connecting rods 214 to form a stable frame structure.

[0032] Working principle: When using the device, when it is necessary to process the drill rod, first insert the drill rod into the inner wall of the anti-vibration mechanism 2. When it is necessary to adjust the height, first start the dual-axis motor 14. At this time, the left and right output ends of the dual-axis motor 14 begin to rotate, driving the conical teeth 15 to rotate accordingly. Due to the meshing relationship between the conical teeth 15 and the second conical teeth 16, the second conical teeth 16 will also begin to rotate, thereby driving the rotating rod 17 and the lifting rod transmission gear 18 to rotate. The rotation of the lifting rod transmission gear 18 causes the tooth block 110 meshing with it to drive the lifting rod 19 to slide up and down on the inner wall of the chute bin 12. As the lifting rod 19 moves up and down, the top plate 111 fixed on the top of it will also move up and down accordingly. In this way, the top plate 111 can be adjusted to the appropriate height according to the processing requirements, ensuring that the drill rod is in the best position during the processing, improving the processing accuracy and stability, making the entire lifting process smooth and reliable, avoiding the vibration phenomenon caused by improper height adjustment, and further improving the processing quality;

[0033] When the drill rod needs to be processed, after the drill rod is inserted into the inner walls of the two anti-vibration fixed chambers 21, as the second dual-axis motor 23 is started, the output ends on the left and right sides respectively drive the gears 217 in the two anti-vibration fixed chambers 21 to rotate, and the gear 217 engages with the outer wall of the gear plate 2111, so that the gear plate 2111 rotates between the connecting plate 213 and the second connecting plate 215. This rotation action drives the movement of multiple arc grooves 2112 fixed on one side of the gear plate 2111. Since the arc grooves 2112 are slidably connected to the outer wall of the cylindrical slider 219, as the gear plate 2111 rotates, the cylindrical slider 219 will move along the trajectory of the arc grooves 2112. This design not only The smooth movement of the cylindrical slider 219 is ensured, and the precise control of the movement trajectory of the cylindrical slider 219 is achieved through the guidance of the arc groove. At the same time, the movement of the cylindrical slider 219 drives the L-shaped slide bar 218 fixed to it to slide in the inner wall of the slide bar 216. A plurality of rotating wheels 2110 are fixed to the inner side of the L-shaped slide bar 218. During the movement of the L-shaped slide bar 218, these rotating wheels fit into the outer wall of the drill rod fixed by the inner wall of the anti-vibration fixed bin 21, thereby helping to stabilize the position of the drill rod and reduce the vibration phenomenon during the processing. In addition, the connecting disk 213 and the second connecting disk 215 are fixedly connected by a plurality of connecting rods 214 to form a stable frame structure.

[0034] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
