Description

Technical Field

[0001] The invention relates to the field of nut fillet, and in particular to a fillet adaptive correction mechanism for aluminum bronze rail machine nuts. Background Art

[0002] The adaptive rounding correction mechanism for nuts is a device or system for rounding and correcting the corners of nuts. It is usually used to round the edges of nuts to reduce the dangers caused by sharp edges and improve the safety and comfort of nuts. The device transmits power to the rounding tool so that it can rotate and cut on the surface of the nut.

[0003] Nut chamfering equipment on the market usually needs to replace the drum to adapt to nuts of different sizes. This is mainly because nuts on the market are usually of specific sizes or shapes. If nuts of different specifications need to be processed, the tool needs to be frequently adjusted. Similarly, the tool needs to be assembled according to the specific size of the nut, and nuts of different sizes require tools of different sizes for chamfering. There are large differences in parameters such as size, diameter, inner hole, etc. of nuts of different specifications. Therefore, corresponding tools need to be used for nuts of different sizes to ensure the accuracy of chamfering. Replacing the tool requires stopping the machine for adjustment, which will cause stagnation of the production line and reduced production efficiency. Separate tools are required for each nut size, which increases the purchase cost and maintenance cost of the equipment. At the same time, operators need time and technical expertise to ensure correct installation and adjustment. Each tool change requires readjustment of the equipment, which increases the complexity of operation and is prone to errors.

[0004] In addition, the nut chamfering equipment on the market can usually only fix nuts of a specific size, so the equipment can only process nuts of fixed sizes, which limits the flexibility and adaptability of the production line. If nuts of different sizes need to be processed, additional equipment or manpower may be required to adapt. Secondly, if the nut size changes frequently in production requirements, fixed-size equipment will lead to low equipment utilization. At the same time, each fixed-size equipment requires corresponding space. If nuts of multiple sizes need to be processed, the equipment space in the factory will increase. Therefore, for the production line, equipment that can flexibly adapt to nuts of different sizes is more advantageous.

[0005] Therefore, it is necessary to provide a fillet adaptive correction mechanism for aluminum bronze rail machine nuts to solve the above problems. Summary of the Invention

[0016] The invention provides an adaptive fillet correction mechanism for aluminum bronze rail machine nuts. Compared with the prior art, the invention has the following beneficial effects:

[0017] 1. Through the setting of the angle adaptive component, when the hollow tube pushes the driving rod to move, the driving rod will push the sliding ring to move along the positioning column, and when the sliding ring moves, it will drive the rotating rod group to rotate, thereby increasing the gap between the sliding ring and the arc grinding tool, so that the arc grinding tool can grind larger nuts, thereby ensuring that the chamfering process of each nut can be carried out according to the preset standards, thereby improving the processing accuracy. The adaptive correction function can switch the tool gap according to the size of the nut, so that the equipment can adapt to nuts of different specifications and shapes, improving the flexibility and adaptability of production, while avoiding the steps of manual tool replacement, and preventing the reduction of production efficiency due to tool replacement.

[0018] 2. The setting of the triangular block can achieve the goal that when the nut chamfering device drives the tool to grind the nut, the tool needs to grind the nut by rotating. The setting of the triangular block avoids the position deviation of the arc-shaped grinding tool due to the eccentricity of the rotation during the rotation of the tool, and avoids the increase of the grinding size in the process of the arc-shaped grinding tool rounding the nut.

[0019] 3. Through the setting of the triangular clamping assembly, the square slide is driven to slide along the inside of the fixed plate group during the movement of the annular moving rod. At the same time, the square slide can drive the fan-shaped rotating frame to rotate by driving the square cylindrical protrusion plate to move, and indirectly drive the three fan-shaped rotating frames to move toward the center of the positioning frame, so as to achieve the effect of fixing nuts of different sizes. Printing makes the production line more flexible to adapt to market demand and product changes, no longer limited to nuts of a specific size, and makes fuller use of equipment, preventing equipment from being idle or waiting due to insufficient production of nuts of a specific size, and replacing multiple positioning devices that can only fix nuts of a specific size, reducing the equipment space occupied in the factory. At the same time, when the fan-shaped rotating frame collides with the bronze nut, the setting of the first fan-shaped rotating block and the second fan-shaped rotating block achieves the effect of more closely fixing the bronze nut. At the same time, the clamping force point can be automatically adjusted according to the size of the bronze nut, making the fixed bronze nut more stable. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the square slide 38 at one end of 6 is fixedly connected to the distance extending rod 310, and the annular moving rod 36 is sleeved on the outer wall of the distance extending rod 310. The top of the inner cavity of the workbench 11 is symmetrically rotatably connected to an obtuse-angle rotating frame 311, and the two obtuse-angle rotating frames 311 are slidably connected to the bottom of the square cylindrical protrusion plate 39 on one side close to the square cylindrical protrusion plate 39. The outer walls of the two square slides 38 away from the square cylindrical protrusion plate 39 are fixedly connected to a strip protrusion plate 312, and the ends of the two obtuse-angle rotating frames 311 away from the square cylindrical protrusion plate 39 are slidably connected to the bottom of the strip protrusion plate 312. The tops of the three square slides 38 are all rotatably connected to a fan-shaped rotating frame 313, and the interior of the fan-shaped rotating frame 313 is symmetrically rotatably connected to the first fan-shaped rotating block 314, and the interiors of the two first fan-shaped rotating blocks 314 are symmetrically rotatably connected to the second fan-shaped rotating block 315.

[0040] The end of the driving rod 23 away from the hollow tube 22 is slidably connected to the inside of the cylindrical groove 26, so that the driving rod 23 can move against the triangular block 29, and the driving rod 23 is adapted to the shape of the hollow tube 22, so that the driving rod 23 can slide inside the hollow tube 22, and the triangular block 29 is set as a slope on the side close to the sliding ring 25, so that the triangular block 29 can be slid against by the driving rod 23, and the triangular block 29 is slidably connected to the inside of the cylindrical groove 26, so that the triangular block 29 can slide into the inside of the cylindrical groove 26.

[0041] A control valve is provided at one end of the first ventilation pipe 32 close to the air pump 31, so that the staff can control the air circulation in the first ventilation pipe 32. The shape of the square slide 38 is adapted to the shape of the fixed plate group 37, so that the square slide 38 can slide inside the fixed plate group 37. The second fan-shaped rotating block 315 is provided with anti-slip grooves on the side away from the first fan-shaped rotating block 314, so that the second fan-shaped rotating block 315 can clamp the bronze nut 13 more stably.

[0042] When the staff needs to process a larger-sized bronze nut 13, the staff first needs to turn on the air pump 31, and then the air pump 31 sends air into the interior of the trigger box 21. At this time, the air pressure inside the trigger box 21 increases, and then the trigger box 21 pushes the driving rod 23 to slide along the inside of the hollow tube 22. At this time, the bottom of the driving rod 23 will slide along the inside of the cylindrical groove 26, and during the movement of the driving rod 23, it will first resist the inclined surface of the triangular block 29, and then the driving rod 23 will push the triangular block 29 to slide toward the inside of the square groove 28. At the same time, the triangular block 29 gradually compresses the reset spring 210, and wait for the triangular block to After 29 slides to the inside of the square groove 28, the driving rod 23 continues to move to push the sliding ring 25 to slide downward along the outer wall of the positioning column 24, and then the positioning column 24 drives the rotating rod group 211 to slide away from one end of the arc-shaped grinding tool 212 toward the limit ring 27. When the bottom of the positioning column 24 conflicts with the limit ring 27, the positioning column 24 pushes the arc-shaped grinding tool 212 to move away from the positioning column 24 through the rotating rod group 211, thereby increasing the distance between the arc-shaped grinding tools 212, so that the arc-shaped grinding tools 212 can grind bronze nuts 13 of larger sizes.

[0043] Working principle: In the initial state, the return spring 210 is not compressed, the square slide 38 is located on the side of the fixed plate group 37 away from the center of the workbench 11, the triangular block 29 is located inside the cylindrical groove 26, and the sliding ring 25 is located in the middle of the positioning column 24.

[0044] During operation, the staff first needs to place the bronze nut 13 on the top of the workbench 11, and then the staff turns on the air pump 31. Then the air pump 31 starts to extract air from the hydraulic rod 35 through the second ventilation pipe 33. At this time, the output end of the hydraulic rod 35 drives the distance extending rod 310 to move through the annular movable rod 36, and the distance extending rod 310 drives the square slide 38 to slide. Because the shape of the square slide 38 is compatible with the shape of the fixed plate group 37, the distance extending rod 310 then drives the square slide 38 to slide along the inside of the fixed plate group 37. When the square slide 38 slides along the fixed plate group 37 toward the center of the workbench 11, the square slide 38 will drive the square cylindrical bump plate 39 to move synchronously toward the center of the workbench 11.

[0045] When the square cylindrical protrusion plate 39 slides toward the center of the workbench 11, the square cylindrical protrusion plate 39 will simultaneously drive the two obtuse-angle rotating frames 311 to rotate toward the center of the workbench 11. While the two obtuse-angle rotating frames 311 are rotating, the ends of the two obtuse-angle rotating frames 311 away from the square cylindrical protrusion plate 39 will drive the two strip-shaped protrusion plates 312 to move away from the center of the workbench 11. Then, the two strip-shaped protrusion plates 312 will drive the remaining two square slides 38 to slide along the fixed plate group 37 toward the center of the workbench 11.

[0046] When the three square slides 38 all slide toward the center of the workbench 11, the three square slides 38 will drive the top fan-shaped rotating frame 313 to move toward the bronze nut 13, and the fan-shaped rotating frame 313 will drive the first fan-shaped rotating block 314 and the second fan-shaped rotating block 315 inside to move toward the bronze nut 13. Then the second fan-shaped rotating block 315 will first contact the bronze nut 13, and the second fan-shaped rotating block 315 will rotate around the first fan-shaped rotating block 314 according to the bronze nuts 13 of different sizes. At the same time, the first fan-shaped rotating block 314 will adjust around the fan-shaped rotating frame 313 according to the angle of fit between the second fan-shaped rotating block 315 and the bronze nut 13. At the same time, the second fan-shaped rotating block 315 is provided with an anti-slip groove on the side away from the first fan-shaped rotating block 314, so that the second fan-shaped rotating block 315 clamps the bronze nut 13 more stably, thereby achieving the purpose of stably clamping the bronze nut 13.

[0047] After the equipment has completed rounding the bronze nut 13, in the opposite direction of the above movement process, the staff controls the air pump 31 to inject air into the hydraulic rod 35, so that the output end of the hydraulic rod 35 drives the distance extending rod 310 to slide away from the center of the workbench 11 through the annular moving rod 36, and the distance extending rod 310 drives the square slide 38 to slide along the fixed plate group 37 away from the center of the workbench 11, and the square slide 38 drives the two obtuse-angle rotating frames 311 to rotate away from the center of the workbench 11 through the square cylindrical protrusion plate 39. Then, the obtuse-angle rotating frame 311 away from the square cylindrical protrusion plate 39 at one end drives the two strip protrusion plates 312 to move in the opposite direction. At this time, the two strip protrusion plates 312 drive the remaining two square slides 38 to reset.

[0048] Finally, the three square slides 38 all drive the top fan-shaped rotating frame 313 to move away from the bronze nut 13, and then the fan-shaped rotating frame 313 drives the first fan-shaped rotating block 314 and the second fan-shaped rotating block 315 to move, at this time releasing the clamping of the bronze nut 13. Through the setting of the triangular clamping assembly, the square slide 38 is driven to slide along the inside of the fixed plate group 37 during the movement of the annular moving rod 36. At the same time, the square slide 38 can drive the fan-shaped rotating frame 313 to rotate by driving the square columnar protrusion plate 39 to move. , and at the same time indirectly drives the three sector-shaped rotating frames 313 to move toward the center of the positioning frame 12. Finally, the three sector-shaped rotating frames 313 will conflict with the bronze nut 13, and when the three sector-shaped rotating frames 313 conflict with the bronze nut 13, they will have a clamping effect on it. Because the staff controls the air pump 31 to inject air into the hydraulic rod 35, the output end of the hydraulic rod 35 drives the distance extending rod 310 to slide away from the center of the workbench 11 through the annular moving rod 36, thereby achieving the purpose of indirectly fixing the bronze nut 13 through the movement of the annular moving rod 36;

[0049] Since the sizes of the bronze nuts 13 are different, when the fan-shaped rotating frame 313 contacts the bronze nut 13, the setting of the first fan-shaped rotating block 314 and the second fan-shaped rotating block 315 can achieve the effect of more accurately fixing the bronze nut 13. At the same time, the clamping force point can be automatically adjusted according to the size of the bronze nut 13, so that the bronze nut 13 can be fixed more stably, and the effect of fixing nuts of different sizes can be achieved. Therefore, the production line can be more flexible to adapt to market demand and product changes, no longer limited to nuts of a specific size, and more fully utilize the equipment, preventing the equipment from being idle or waiting due to insufficient production of nuts of a specific size, and replacing multiple positioning devices that can only fix nuts of a specific size, reducing the equipment space occupied in the factory.

[0050] When the staff needs to process a larger-sized bronze nut 13, the staff first needs to turn on the air pump 31, and then the air pump 31 sends air into the interior of the trigger box 21. At this time, the air pressure inside the trigger box 21 increases. Because the driving rod 23 is adapted to the shape of the hollow tube 22, the air inside the trigger box 21 then pushes the driving rod 23 to slide along the inside of the hollow tube 22. Because the end of the driving rod 23 away from the hollow tube 22 is slidably connected to the inside of the cylindrical groove 26, the bottom of the driving rod 23 will slide along the inside of the cylindrical groove 26. Because the side of the triangular block 29 close to the sliding ring 25 is set as an inclined surface, and the triangular block 29 is slidably connected to the inside of the cylindrical groove 26, the process of the driving rod 23 moving The center will first contact the inclined surface of the triangular block 29, and then the driving rod 23 pushes the triangular block 29 to slide inside the square groove 28. At the same time, the triangular block 29 gradually compresses the reset spring 210. Through the arrangement of the triangular block 29, when the nut inner angle chamfering device drives the tool to grind the nut, the tool needs to grind the nut by rotating. The arrangement of the triangular block 29 prevents the arc-shaped grinding tool 212 from sliding toward the limit ring 27 due to the eccentricity of the rotation during the rotation of the tool, resulting in the deviation of the arc-shaped grinding tool 212 during the grinding process, thereby avoiding the increase of the grinding size during the process of the arc-shaped grinding tool 212 rounding the nut.

[0051] When the bottom of the positioning post 24 conflicts with the limiting ring 27, the positioning post 24 pushes the arc grinding tool 212 to move away from the positioning post 24 through the rotating rod group 211, thereby increasing the distance between the arc grinding tools 212. Finally, when the positioning frame 12 drives the limiting ring 27 to vibrate, the limiting ring 27 will drive the arc grinding tool 212 to vibrate through the rotating rod group 211, and the bottom of the arc grinding tool 212 conflicts with the top of the bronze nut 13. Therefore, during the vibration of the arc grinding tool 212, the bronze nut 13 will be polished, thereby making the positioning post 24 and the limiting ring 27 move in the same direction. The arc-shaped grinding tool 212 can grind larger bronze nuts 13. Through the setting of the angle adaptive component, when the hollow tube 22 pushes the driving rod 23 to move, the driving rod 23 will push the sliding ring 25 to move along the positioning column 24, and when the sliding ring 25 moves, it will drive the rotating rod group 211 to rotate, thereby increasing the gap between the sliding ring 25 and the arc-shaped grinding tool 212, so that the arc-shaped grinding tool 212 can grind larger nuts, thereby ensuring that the chamfering process of each nut can be carried out according to the preset standards, thereby improving the processing accuracy. The adaptive correction function can switch the tool gap according to the size of the nut, so that the equipment can adapt to nuts of different specifications and shapes, thereby improving the flexibility and adaptability of production, while avoiding the steps of manual tool replacement, and preventing the reduction in production efficiency due to tool replacement.

[0052] Because a control valve is provided at one end of the first ventilation pipe 32 close to the air pump 31 , the staff can control the air pressure inside the trigger box 21 through the control valve, thereby achieving the effect of controlling the spacing of the arc grinding tools 212 through the above steps.
