Description

Technical Field

[0001] This utility model belongs to the field of nut processing technology, specifically a multi-point positioning structure for nut processing. Background Technology

[0002] Nuts, as basic mechanical fasteners, have evolved in processing technology from manual forging and lathe cutting to modern automated production. During nut processing, the nut is fixed in place, and a drilling mechanism is used to drill a hole in its center. A positioning structure is required during nut processing.

[0003] The existing positioning and clamping mechanism is used to fix the nut by clamping on both sides. This limited positioning and clamping mechanism may result in loosening and instability when clamping the nut. In addition, the limited positioning and clamping mechanism can cause the clamping force to be dispersed when clamping the nut, and applying pressure to a single point can easily cause the workpiece to deform. Furthermore, it is not suitable for fixing different types of nuts. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a multi-point positioning structure for nut processing. It solves the problem that the existing positioning is achieved by clamping and fixing through clamping mechanisms on both sides. This type of positioning and clamping mechanism with fewer points may result in loosening and instability when clamping and fixing the nut. Furthermore, the positioning and clamping mechanism with fewer points disperses the clamping force when clamping the nut, and applying pressure at a single point can easily cause workpiece deformation. In addition, it is not suitable for fixing nuts of different models.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-point positioning structure for nut processing, comprising a positioning body, an installation groove inside the positioning body, a fixing plate fixedly connected to the inner wall of the installation groove, a rotating groove on the top of the fixing plate, an installation ring rotatably connected through the rotating groove, a toothed ring fixedly connected to the outer arc surface of the installation ring, a servo motor fixedly connected to the top of one side of the installation groove, a rotating gear fixedly connected to the output end of the servo motor, the bottom of the rotating gear rotatably connected to the top of the fixing plate via a bearing, the rotating gear meshing with the toothed ring, five mounting blocks evenly fixedly connected to the top of the fixing plate, a clamping rod rotatably connected to the top of each mounting block via a rotating shaft, a rotating cylinder sleeved on the surface of the clamping rod, and the bottom of the rotating cylinder rotatably connected to the installation ring via a rotating shaft.

[0006] As a further embodiment of this utility model: one end of the clamping rod is fixedly connected to a rubber fixing wheel, and the tops of the four rotating cylinders are rotatably connected to the same fixing ring via a rotating shaft.

[0007] As a further embodiment of this utility model: the inner bottom of the mounting groove is rotatably connected to a second bevel gear via a bearing, the top of the second bevel gear is fixedly connected to a mounting cylinder, and a threaded rod is threadedly connected inside the mounting cylinder.

[0008] As a further embodiment of this utility model: the top of the threaded rod is rotatably connected to a lifting platform, and the bottom of the lifting platform is fixedly connected to four elastic telescopic rods, the bottom of which is fixedly connected to the bottom wall of the mounting groove.

[0009] As a further embodiment of this utility model: the first bevel gear meshes with one side of the second bevel gear, and a rotating rod is fixedly connected to one side of the first bevel gear.

[0010] As a further embodiment of this utility model: the rotating rod is rotatably connected inside the positioning body, and a rotating handle is fixedly connected to one end of the rotating rod located outside the positioning body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This multi-point positioning structure for nut processing, consisting of a servo motor, rotating gears, mounting blocks, and clamping rods, allows the servo motor to rotate when the nut needs to be clamped and fixed. This rotation drives the rotating gears, which in turn rotate the gear ring and mounting ring. The mounting ring then rotates the rotating cylinder, causing the clamping rods to rotate around their connection with the mounting block. This allows for angle adjustment of the clamping rods. When all four clamping rods and rubber fixing wheels simultaneously contact the nut, the four rubber fixing wheels fix the nut at the center of the lifting platform. This multi-point clamping and positioning ensures a more secure clamping of the nut, preventing loosening during processing. Furthermore, it prevents deformation of the nut blank caused by single-point pressure by positioning the nut at the center through multiple points.

[0013] 2. This multi-point positioning structure for nut processing, by setting a rotating handle, a rotating rod, and a second bevel gear, allows the rotating handle and rotating rod to rotate after the nut processing is completed. The rotating rod drives the first and second bevel gears to rotate, which in turn drives the mounting cylinder to rotate. When the mounting cylinder rotates, it drives the threaded rod to rotate inside the mounting cylinder, causing the threaded rod to rotate and rise. At the same time, it drives the lifting platform and the processed nut to rise, thereby adjusting the height of the lifting and lowering to adjust the nut clamping part, making the clamping mechanism clamp the nut more stably. It can also be used to pick up and put down materials by lifting and lowering. Attached Figure Description

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a multi-point positioning structure for nut processing, including a positioning body 1, an installation groove 2 is provided in the positioning body 1, a fixing plate 3 is fixedly connected to the inner wall of the installation groove 2, a rotating groove 4 is provided on the top of the fixing plate 3, and an installation ring 5 is rotatably connected through the rotating groove 4. By setting the rotating groove 4, the installation ring 5 can be easily installed, and the installation ring 5 can rotate within the rotating groove 4. The rotating groove 4 also limits the installation ring 5 to prevent it from shifting when rotating.

[0020] A toothed ring 6 is fixedly connected to the outer arc surface of the mounting ring 5. A servo motor 7 is fixedly connected to the top of one side of the mounting groove 2. A rotating gear 8 is fixedly connected to the output end of the servo motor 7. The bottom of the rotating gear 8 is rotatably connected to the top of the fixing plate 3 through a bearing. The rotating gear 8 meshes with the toothed ring 6. Through the arrangement of the rotating gear 8 and the toothed ring 6, the rotating servo motor 7 drives the rotating gear 8 to rotate, and then drives the toothed ring 6 to rotate, thereby enabling the servo motor 7 to control the rotation of the toothed ring 6 and the mounting ring 5.

[0021] Five mounting blocks 9 are evenly fixedly connected to the top of the fixed plate 3. The number of mounting blocks 9 is five. The top of the mounting blocks 9 is rotatably connected to the clamping rod 10 through a rotating shaft. The surface of the clamping rod 10 is sleeved with a rotating cylinder 12. The bottom of the rotating cylinder 12 is rotatably connected to the mounting ring 5 through a rotating shaft. By setting the rotating cylinder 12, when the clamping rod 10 rotates, the clamping rod 10 can move inside the rotating cylinder 12 at the same time, ensuring that the clamping rod 10 can rotate stably.

[0022] One end of the clamping rod 10 is fixedly connected to a rubber fixing wheel 11. The tops of the four rotating cylinders 12 are rotatably connected to the same fixing ring 13 through a rotating shaft. The fixing ring 13 limits the four rotating cylinders 12 to prevent the rotating cylinders 12 from not changing angle when rotating.

[0023] The bottom of the mounting groove 2 is rotatably connected to a second bevel gear 17 via a bearing. The top of the second bevel gear 17 is fixedly connected to a mounting cylinder 18. A threaded rod 19 is threadedly connected inside the mounting cylinder 18. A lifting platform 20 is rotatably connected to the top of the threaded rod 19. Four elastic telescopic rods 21 are fixedly connected to the bottom of the lifting platform 20. The bottom of the elastic telescopic rods 21 is fixedly connected to the bottom wall of the mounting groove 2. Through the setting of the threaded rods 19 and the lifting platform 20, the rotating mounting cylinder 18 drives the threaded rods 19 to rotate. At this time, the threaded rods 19 will rise and drive the lifting platform 20 to rise. At the same time, the elastic telescopic rods 21 follow the lifting platform 20 to rise. The elastic telescopic rods 21 limit the lifting platform 20 to prevent the lifting platform 20 from rotating with the threaded rods 19. This allows the lifting platform 20 to drive the nut to discharge material.

[0024] The first bevel gear 16 is meshed on one side of the second bevel gear 17. A rotating rod 15 is fixedly connected to one side of the first bevel gear 16. The rotating rod 15 is rotatably connected inside the positioning body 1. A rotating handle 14 is fixedly connected to one end of the rotating rod 15 outside the positioning body 1. Through the arrangement of the first bevel gear 16 and the second bevel gear 17, the rotating rod 15 drives the first bevel gear 16 to rotate, and then the first bevel gear 16 drives the second bevel gear 17, so that the second bevel gear 17 can drive the mounting cylinder 18 to rotate.

[0025] The working principle of this utility model is as follows: First, the nut is placed on the lifting platform 20. When the nut is clamped and positioned, the servo motor 7 is started, and the output end of the servo motor 7 drives the rotating gear 8 to rotate. Then, the rotating gear 8 drives the gear ring 6 and the mounting ring 5 to rotate in the rotating groove 4. The mounting ring 5 drives the rotating cylinder 12 to rotate. At the same time, the clamping rod 10 is driven by the rotating cylinder 12 to rotate around the connection point with the mounting block 9, thereby driving the clamping rod 10 to adjust its angle. This allows all four clamping rods 10 to simultaneously drive the rubber fixing wheels 11 to position the nut. Once fixed and positioned, processing can begin. After processing, the handle 14 can be rotated, which in turn rotates the rod 15. The rod 15 then rotates the first bevel gear 16, which in turn rotates the second bevel gear 17. The mounting cylinder 18 rotates synchronously with the second bevel gear 17, causing the threaded rod 19 to rotate within the cylinder. This causes the threaded rod 19 to rise, and as it rises, the lifting platform 20 and the nut also rise, making it easier for workers to pick up.
