Abstract
Description
Technical Field
[0001] This utility model belongs to the manufacturing industry, and specifically relates to a grinding equipment for fastener production and processing. Background Technology
[0002] In the production and processing of fasteners, the grinding process is crucial. With the rapid development of industry, the requirements for the quality and performance of fasteners are increasing. Traditional grinding methods often rely on simple grinding tools operated manually, such as sandpaper and grinding wheels. However, this manual grinding method has many limitations. With the continuous advancement of mechanical manufacturing technology, automation control technology, and materials science, developing a high-efficiency, precise, and automated grinding equipment for fastener production and processing has become an inevitable trend. This equipment can effectively overcome many drawbacks of manual grinding. Through advanced mechanical structure design, precise grinding process control, and a complete automated operating system, it can achieve high-quality and rapid grinding of fasteners, improve production efficiency, reduce production costs, enhance the market competitiveness of enterprises, and provide more reliable and high-quality fastener products for industrial production.
[0003] One drawback of a fastener grinding machine is its limited compatibility with different fasteners. Although designed for fastener grinding, different types and sizes of fasteners may present adaptation challenges. For example, the machine might be optimized for a specific range of bolt or nut sizes. When grinding fasteners with significant size differences or unique shapes (such as irregular nuts or bolts with special patterns), adjustments to the machine's fixtures and grinding parameters may be necessary, potentially preventing effective grinding. Another drawback is clogging. If grinding debris is not cleaned promptly, it can easily accumulate and clog critical parts of the grinding machine. For instance, debris may enter the vicinity of the grinding head's rotating shaft, increasing friction and reducing its rotational speed and accuracy. Over time, this clogging can prevent the rotating shaft from functioning properly, affecting the normal operation of the grinding machine and impacting grinding quality. Accumulated debris also negatively affects grinding quality. When debris adheres to the surface of the grinding tool, it alters the contact state between the tool and the fastener. For example, when using a grinding wheel for grinding, debris can become embedded between the abrasive grains of the wheel, reducing the grinding ability of the wheel and resulting in uneven surface roughness of the fasteners after grinding, failing to meet the expected quality standards.

[0025] Please see Figure 1-5 The technical solution provided in this embodiment is as follows:
[0026] A grinding device for fastener manufacturing and processing, comprising,
[0027] Outer shell 1;
[0028] An internal expansion fixing assembly is located inside the outer casing 1. The internal expansion fixing assembly includes a limiting ring 2, a sliding ring 3, a first connecting rod 4, a second connecting rod 5, a first fixing ring 6, a support rod 7, a third connecting rod 8, a second fixing ring 9, and a fixing post 10. The limiting ring 2 is slidably connected to the outer wall of the fixing post 10. The sliding ring 3 is slidably connected to the outer wall of the fixing post 10. One end of the first connecting rod 4 is rotatably mounted on the outer wall of the sliding ring 3, and the other end of the first connecting rod 4 is rotatably mounted on the outer wall of the support rod 7. One end of the second connecting rod 5 is rotatably mounted on the outer wall of the first fixing ring 6, and the other end of the second connecting rod 5 is rotatably mounted on the outer wall of the support rod 7. The first fixing ring 6 is fixedly sleeved on the outer wall of the fixing post 10. One end of the third connecting rod 8 is rotatably mounted on the outer wall of the support rod 7, and the other end of the third connecting rod 8 is rotatably mounted on the outer wall of the second fixing ring 9. The second fixing ring 9 is fixedly sleeved on the outer wall of the fixing post 10. The fixing post 10 is fixedly located at the bottom of the inner wall of the outer casing 1.
[0029] In a specific embodiment of this utility model, the internal expansion fixing component can secure the fastener to the fixing post 10. When the internal expansion component functions, it generates an outward expansion force inside the fixing post 10, firmly securing the fastener to the fixing post 10 and effectively preventing loosening or displacement of the fastener during use. The internal expansion fixing method allows for a more even distribution of pressure across the entire connection surface, thereby extending the service life of the fixing post 10 and the fastener. The movable grinding disc 16 can be flexibly moved to various grinding locations according to the shape of the fastener. The suction force generated by the rotation of the fan blade 22 can cover a certain area, effectively preventing loosening or displacement of the fastener. The dust pan can capture debris within this suction range, preventing the spread of debris during the grinding process. First, the cylinder 12 is activated, causing the lifting ring 11 to push the limiting ring 2 upward. At the same time, the first connecting rod 4 rotates, and the first fixing ring 6 and the second fixing ring 9, which are fixed on the fixed column 10, remain stationary. Under the combined action of the second connecting rod 5 and the third connecting rod 8, the support rod 7 can expand outward, thereby generating an outward expansion force inside the fixed column 10, so that the fastener is firmly fitted onto the fixed column 10. Specifically, the lifting ring 11 is fixedly installed at the bottom of the outer wall of the limiting ring 2, and the cylinder 12 is fixedly installed at the bottom of the outer wall of the lifting ring 11.
[0030] In a specific embodiment of this utility model, starting the cylinder 12 can cause the lifting ring 11 to push the limiting ring 2 upward.
[0031] Specifically, a first motor 13 is fixedly installed on the outer wall of the outer casing 1, a limiting groove 17 is opened on the inner wall of the outer casing 1, a lead screw 18 is rotatably embedded in the inner wall of the limiting groove 17, a lifting rod 15 is threadedly connected to the outer wall of the lead screw 18, a second motor 14 is fixedly installed on the outer wall of the lifting rod 15, and a grinding disc 16 is fixedly installed at the output end of the second motor 14.
[0032] In a specific embodiment of this utility model, starting the first motor 13 can adjust the position of the grinding disc 16, adjusting the lifting rod 15 can adjust the height of the grinding disc 16, and starting the second motor 14 can make the grinding disc 16 start working.
[0033] Specifically, a dust collection disc 19 is fixedly installed on the inner wall of the outer casing 1, a third motor 21 is fixedly installed on the outer wall of the outer casing 1, a dust collection box 20 is fixedly installed on the outer wall of the outer casing 1, and a fan blade 22 is fixedly installed at the output end of the third motor 21.
[0034] In a specific embodiment of this utility model, starting the third motor 21 can cause the fan blade 22 to start rotating. When the fan blade 22 rotates at high speed, it will quickly draw away the air in the central area of the dust collection disk 19, making the air pressure inside the dust collection disk 19 lower than the external air pressure. This air pressure difference will generate a strong suction force, which can suck all the debris generated during polishing into the dust collection box 20.
[0035] Specifically, a protective shell 23 is fixedly installed on the outer wall of the lifting rod 15.
[0036] In a specific embodiment of this utility model, the protective shell 23 can serve as a protective barrier to prevent the grinding disc 16 from being subjected to accidental impacts.
[0037] Specifically, the outer wall of the dust collection disk 19 has filter holes.
[0038] In a specific embodiment of this utility model, the filter holes on the outer wall of the dust collection disk 19 can perform preliminary screening and filtration of dust during the dust collection process.
[0039] Working principle:
[0040] The internal expansion fixing component can secure the fastener to the fixing post 10. When the internal expansion component functions, it generates an outward expansion force inside the fixing post 10, firmly securing the fastener to the fixing post 10 and effectively preventing loosening or displacement of the fastener during use. The internal expansion fixing method allows the pressure to be distributed more evenly across the entire connection surface, thereby extending the service life of the fixing post 10 and the fastener. The movable grinding disc 16 can flexibly move to various grinding positions according to the shape of the fastener. Since the suction force generated by the rotation of the fan blade 22 can cover a certain range, the dust collection disc can capture debris within this suction range, preventing the spread of debris during grinding. First, the cylinder 12 is activated, causing the lifting ring 11 to push the limit ring 2 upward. At the same time, the first connecting rod... 4. Rotation: The first fixing ring 6 and the second fixing ring 9, which are fixed on the fixed column 10, remain stationary. Under the combined action of the second connecting rod 5 and the third connecting rod 8, the support rod 7 can expand outward, thereby generating an outward expansion force inside the fixed column 10, so that the fastener is firmly fitted onto the fixed column 10. Starting the first motor 13 can adjust the position of the grinding disc 16, and adjusting the lifting rod 15 can adjust the height of the grinding disc 16. Starting the second motor 14 can start the grinding disc 16 to work, and starting the third motor 21 can start the fan blade 22 to rotate. When the fan blade 22 rotates at high speed, it will quickly draw the air away from the central area of the dust collection disc 19, making the air pressure inside the dust collection disc 19 lower than the external air pressure. This air pressure difference will generate a strong suction force, which can suck all the debris generated during grinding into the dust collection box 20.
[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
