The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0020] As Figures 1 to 14 shown, a grinding device for a tip lightning arrester 10 of the present invention includes: a processing table 1, a grinding mechanism 2 installed on the processing table 1, a pushing mechanism 3 for pushing the tip lightning arrester 10 close to the grinding mechanism 2, and a cleaning mechanism 4 for cleaning the lightning arrester after grinding. The specific structure of the lightning arrester is as Figure One 、 Figure Two shown. An installation groove 11 is provided on the lightning arrester body, and a plug hole 12 is provided in the installation groove 11. When installing the lightning arrester at the end of the fan blade, the lightning arrester body can be detachably installed at the end of the fan blade through the installation groove 11. Since the fan blade seat is a streamline structure, the lightning arrester body and the fan blade are formed into one body, avoiding the influence of the lightning arrester body on the operation of the fan blade. By adding a locking bolt, the fan blade seat can be stably plugged and installed on the fan blade through the locking bolt and the plug hole 12, facilitating the replacement of the lightning arrester body.

[0021] The device further includes a feeding mechanism 5. The feeding mechanism 5 is used to convey the lightning arrester to be ground onto the processing table 1, and then the six-axis manipulator 6 grabs the lightning arrester conveyed onto the processing table 1 onto the pushing mechanism 3 for fixation. It should be noted here that the feeding structure and the six-axis manipulator 6 are prior arts, so they will not be elaborated here.

[0022] The pushing mechanism 3 includes: a mounting head 31 for fixing the lightning arrester, and a cylinder 32 for driving the mounting head 31 to move. The piston rod of the cylinder 32 is rotationally connected to the mounting head 31 through a rotary joint.

[0023] The six-axis manipulator 6 inserts the lightning arrester on the conveying mechanism onto the mounting head 31, and then the cylinder 32 pushes the mounting head 31 close to the grinding mechanism 2 for grinding.

[0024] The mounting head 31 is composed of a plug-in block 311 matching the mounting groove 11, a jacking cavity 312 opened on the plug-in block 311, a pressing rod 313 slidably installed in the jacking cavity 312, and a locking rod 314; the jacking cavity 312 is divided into a pressing cavity 3121 and a locking cavity 3122; the pressing rod 313 is slidably installed in the pressing cavity 3121; the locking rod 314 is slidably installed in the locking cavity 3122; one side of the pressing rod 313 is elastically installed with a pressing plate 3125 through a spring 3124.

[0025] After the manipulator grabs the lightning arrester to be ground, its mounting groove 11 is aligned with and inserted into the mounting head 31. As the mounting head 31 gradually penetrates into the mounting groove 11, the pressing rod 313 retracts into the pressing cavity 3121 under the action of the inner wall of the mounting groove 11. This process causes the pressure in the pressing cavity 3121 to increase suddenly, thereby driving the locking rod 314 in the locking cavity 3122 to move upward along a preset path until it firmly inserts into the plug-in hole 12 of the lightning arrester, thus realizing the quick and firm fixation of the lightning arrester on the mounting head 31.

[0026] In particular, due to the design of the elastic pressing plate 3125 installed on one side of the pressing rod 313, when the plug-in hole 12 is not yet aligned with the locking cavity 3122, the pressing rod 313 first compresses the spring 3124; once the plug-in hole 12 is aligned with the locking cavity 3122, the spring 3124 uses its elastic potential energy to push the pressing plate 3125, resulting in an increase in the pressure in the jacking cavity 312, prompting the locking rod 314 to extend and insert into the locking groove at the precise alignment moment, enhancing the reliability of the fixation.

[0027] After the grinding process of the lightning arrester is completed, for easy disassembly, the manipulator is equipped with a convex rod that precisely matches the plug-in hole 12. When the manipulator grabs the lightning arrester again, the convex rod precisely inserts into the plug-in hole 12, forcing the locking rod 314 originally jacked in the plug-in hole 12 to move downward synchronously under the extrusion of the convex rod, releasing the locked state of the lightning arrester, thereby realizing the efficient and convenient disassembly of the lightning arrester from the mounting head 31.

[0028] Through the above structure, the quick and stable fixation and efficient disassembly of the lightning arrester on the mounting head 31 are realized, significantly improving the operation efficiency and convenience.

[0029] The grinding mechanism 2 includes: a grinding piece 21 for grinding the lightning arrester, a probe 22 for detecting the lightning arrester, and a synchronizing piece 23 for synchronizing the probe 22 and the grinding piece 21; While the lightning arrester to be polished is transported by the pushing mechanism 3 to the lower part of the polishing assembly, the pushing mechanism 3 also synchronously transfers the finished product tip lightning arrester 13 that has completed processing to directly below the detection probe 22, as Figure 4 shown. As the pushing process progresses, the finished lightning arrester gradually passes through the area of the detection probe 22, and the probe 22 adjusts its vertical displacement according to the dynamic change of the arc of the lightning arrester. During this process, the polishing assembly uses a synchronization mechanism to ensure that it maintains a constant height consistency with the probe 22. Thus, when polishing the arc surface of the lightning arrester, the polishing piece 21 can closely follow the arc fluctuation of the finished lightning arrester and float up and down, thereby realizing efficient polishing operations. It should be added here that the polishing assembly is internally provided with a floating spring 3124 device to prevent the lightning arrester to be polished from being damaged due to insufficient polishing in a short time due to an excessive polishing stroke, effectively improving the safety and quality of the processed product.

[0030] Here, the synchronizer 23 can be understood as a rigid hard connection.

[0031] Through synchronous control, an efficient and safe dynamic polishing operation of the arc surface of the lightning arrester is realized.

[0032] The cleaning mechanism 4 includes: a cleaning rack 41 fixedly installed on the processing table 1, a cleaning groove 42 opened on the cleaning rack 41, a soft rack 43 slidably installed in the cleaning groove 42, a brush 44 fixedly installed on the non-tooth surface of the soft rack 43, and a cleaning component 45 for cleaning the brush 44; When one side of the lightning arrester is polished, at this time, the air cylinder 32 retracts, and the lightning arrester moves backward synchronously. At this time, the lightning arrester will pass through the cleaning rack 41. When passing through the cleaning rack 41, the brush 44 on the cleaning rack 41 will clean the surface of the polished lightning arrester.

[0033] It should be noted here that the soft rack is made of a composite of a high-elastic rubber matrix and reinforcing fibers, and the surface teeth are formed by polyurethane injection molding. Its elastic modulus is controlled within the range of 20 - 50 MPa, which can not only maintain the tooth profile meshing accuracy (tooth pitch error ≤ 0.1 mm), but also achieve a radial deformation of ±5 mm; specifically, a product with the product number 03142 of Hengshui Chiao Rubber and Plastic Products Co., Ltd. can be used; thus, when the motor 452 rotates, the soft rack 43 can move freely along the shape in the cleaning groove 42, so that when designing the cleaning rack 41 and the cleaning groove 42, the cleaning brush can fit the lightning arrester at multiple angles, thereby enhancing the cleaning effect.

[0034] The cleaning assembly 45 includes: a first gear 451 meshing with the soft rack 43, a motor 452 driving the first gear 451 to rotate, a lever 453 moving with the brush 44 to sweep the brush 44, and a turning-over assembly 454 for turning over the lightning arrester; the motor 452 is coaxially and fixedly connected to the first gear 451; the lever 453 is fixedly connected to the cleaning frame 41.

[0035] When the lightning arrester passes through the cleaning frame 41, the motor 452 is started. The motor 452 drives the first gear 451 to rotate, and the first gear 451 drives the soft rack 43 to move in the cleaning groove 42. At this time, the brush 44 moves synchronously with the soft rack 43. During the movement of the brush 44, the lever 453 mechanically disturbs the brush 44 to effectively disperse and shake off the metal chips attached to the surface of the brush 44, laying a solid foundation for the smooth progress of the subsequent dust collection and recycling process.

[0036] The turning-over assembly 454 includes: a connecting sleeve 4541 sleeved outside the mounting head 31, a toothed ring 4542 fixedly installed on the connecting sleeve 4541, and a second gear 4543 coaxially and fixedly connected to the motor 452; a guide groove 4544 is formed in the connecting sleeve 4541, and the mounting head 31 is slidably installed in the guide groove 4544.

[0037] When the cylinder 32 drives the mounting head 31 to perform an axial feeding movement, the mounting head 31 makes a first-stage linear displacement along the limiting guide groove 4544 provided in the connecting sleeve 4541. When the displacement reaches the stroke threshold of the guide groove 4544, the linkage displacement of the mounting head 31 and the connecting sleeve 4541 is triggered until the lightning arrester is completely embedded in the machining position of the grinding mechanism 2. At this time, the toothed ring 4542 at the end of the connecting sleeve 4541 and the second gear 4543 at the output end of the motor 452 form a rigid meshing transmission pair; after one-sided grinding is completed, the cylinder 32 executes a reverse retraction command. During the reset process of the mounting head 31 along the guide groove 4544, the lightning arrester is driven to complete surface pretreatment through the cleaning frame 41. When the lightning arrester retracts to the internal protection area of the connecting sleeve 4541, the motor 452 is started, and the first gear 451 and the second gear 4543 rotate synchronously. The first gear 451 rotates to synchronously drive the soft rack 43 to move to clean the brush 44 on the surface of the just-cleaned lightning arrester. At the same time, the second gear 4543 rotates to drive the mounting head 31 to turn over, so as to turn over the lightning arrester and align the unground side of the lightning arrester with the grinding part 21, realizing precise double-sided positioning grinding of the workpiece. It should be noted here that the connecting sleeve 4541 not only serves as a transmission medium for turning over the lightning arrester, but also when cleaning the brush 44, the lightning arrester retracts into the connecting sleeve 4541, and the connecting sleeve 4541 can protect the lightning arrester and prevent the iron chips generated during the cleaning of the brush 44 from adhering to the surface of the lightning arrester again.

[0038] Through the above mechanism, the automatic turning and synchronous cleaning of the lightning arrester are realized, and at the same time, its brush 44 is synchronously cleaned, significantly improving the comprehensiveness and efficiency of the grinding operation, and effectively ensuring the cleanliness of the surface of the lightning arrester.

[0039] The lightning arrester, as a key component of the lightning protection system, is usually carefully made of highly conductive metal materials such as copper, aluminum or galvanized steel alloy; when the lightning arrester is finely polished to optimize its performance, a large amount of precious metal powder will be generated; these powders not only contain rich resource value, but if not recycled, may also cause a burden on the environment; therefore, implementing an efficient metal powder recycling strategy is not only a treasure of industrial resources, but also a responsibility for environmental protection, reflecting the concept of green production and sustainable development.

[0040] A dust suction component is also provided on the lever 453; the dust suction component includes: a dust suction sleeve rod 4531 rotatably installed outside the lever 453, a dust suction port 4532 opened on the dust suction sleeve rod 4531, a negative pressure fan connected to the dust suction sleeve rod 4531, and a swing component for expanding the dust suction area of the dust suction port 4532; The swing component includes: a semi-gear 4533 coaxially and fixedly connected to the motor 452, a gear three 4534 meshing with the semi-gear 4533, and a torsion spring 4535 for driving the gear three 4534 to reset; the gear three 4534 is connected to the dust suction sleeve rod 4531 through a transmission member 4536.

[0041] Under the rotation drive of the motor 452, the semi-gear 4533 and the gear three 4534 achieve meshing transmission, prompting the gear three 4534 to rotate, and then driving the dust suction sleeve rod 4531 to rotate synchronously, in this way dynamically expanding the coverage area of the dust suction port 4532 and enhancing the dust suction efficiency. When the motor 452 drives the semi-gear 4533 to move to the toothless area, the torsion spring 4535 acts as a reset mechanism, driving the gear three 4534 back to its initial position, and the movement of the gear three 4534 synchronously pulls the dust suction sleeve rod 4531 to reset, forming a periodic swing. Thus, when the motor 452 rotates, on the one hand, it drives the brush 44 to rotate, and the lever 453 knocks off the dust on the brush 44. At the same time, the reciprocating swing of the dust suction sleeve rod 4531 further broadens the working range of dust suction and cleaning.

[0042] Through the above structure, the dual functions of self-cleaning of the brush 44 and dynamic dust suction of the dust suction sleeve rod 4531 are realized, and the area and efficiency of dust suction and cleaning are significantly improved.

[0043] It should be added here that multiple groups of the lever 453 and the dust suction sleeve rod 4531 can be provided to achieve more efficient cleaning.

[0044] Working principle: The feeding mechanism 5 transports the lightning arrester to be polished to the lower end of the six-axis robot 6. The six-axis robot 6 clamps it and inserts it onto the mounting head 31. At this time, the air cylinder 32 pushes the mounting head 31 close to the polishing mechanism 2 for polishing. While the lightning arrester to be polished is transported to the lower part of the polishing assembly by the pushing mechanism 3, the pushing mechanism 3 also synchronously transfers the lightning arrester that has completed the processing to directly below the detection probe 22. The polishing assembly uses a synchronization mechanism to ensure that it maintains a constant height consistency with the probe 22. Thus, when performing the polishing operation on the arc surface of the lightning arrester, the polishing assembly can closely follow the arc fluctuation of the finished lightning arrester and float up and down, thereby realizing an efficient polishing operation. When one side of the lightning arrester is polished, the air cylinder 32 executes a reverse retraction command, the motor 452 starts, and the first gear 451 and the second gear 4543 rotate synchronously. When the first gear 451 rotates, it synchronously drives the soft rack 43 to move to clean the brush 44 on the surface of the just-cleaned lightning arrester. At the same time, when the second gear 4543 rotates, it drives the mounting head 31 to flip, thereby turning over the lightning arrester; while the motor 452 is rotating, the half gear 4533 meshes with the third gear 4534 to drive the third gear 4534 to rotate, and then drives the dust suction sleeve rod 4531 to rotate synchronously. In this way, the coverage area of the dust suction port 4532 is dynamically expanded, enhancing the dust suction efficiency.
