[0002] The core function of nuts is to serve as fasteners, connecting and fixing mechanical parts by engaging with the threads of bolts. Their applications cover almost all fields involving mechanical structures, including industrial manufacturing, construction engineering, transportation, and home life.

[0003] In the existing technology, in the process of tapping hexagonal copper nuts, the excellent ductility (elongation after fracture ≥15%) and low hardness characteristics (≤120HB) of copper alloy are often utilized to perform thread deformation processing after tapping to improve its anti-loosening and wear resistance. However, after tapping the copper nut, it needs to be disassembled and transferred to other workstations before thread deformation processing can be performed. Multiple clamping leads to a lengthy process chain, increased labor intensity of workers, and positioning errors reduce processing efficiency. In addition, during the thread deformation processing of the copper nut, the position where the extrusion block extrudes and deforms the thread is usually affected by the placement of the copper nut and the cutting direction of the processing tool, and has a certain degree of randomness. When the extrusion block extrudes and deforms the opening position (starting end) of the thread, the copper nut and the bolt thread cannot accurately match and engage, resulting in thread dislocation or jamming, affecting the normal assembly of the copper nut.

[0014] As a further solution of the present invention, a guiding slope is provided at the upper edge of the synchronization block.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a positioning block to position the opening position of the bottom of the inner thread of the processing nut during the tapping process of the processing nut, so that the position of the extrusion block for extruding and deforming the processing nut can be automatically adjusted according to the different opening positions of the inner thread of the processing nut, ensuring that the deformation processing position of the inner thread of the processing nut by the extrusion block can avoid the opening position of the thread, avoiding the position of the extrusion block for deforming the inner thread of the processing nut cannot be changed, and during a long processing time, it is easy for the thread opening position of the processing nut to be located at the side edge position of the extrusion block, and the thread after extrusion and deformation cannot be matched and engaged with the bolt thread, affecting the assembly of the processing nut and reducing the product qualification rate.

DETAILED DESCRIPTION

[0020] See also Figures 1-16 The present invention provides a technical solution: a wear-resistant and non-slip hexagonal copper nut tapping device for photovoltaic fastening, comprising a base 1, a processing table 2, a movable arm 3, a cooling pipe 4, a tap 5, and a fixing seat 6 fixedly mounted on the surface of the processing table 2 by a clamp and having a hollow interior; The surface of the fixed seat 6 is provided with a clamping mechanism for clamping the processed nut 7. A through-hole 8 is opened on the surface of the fixed seat 6 corresponding to the position of the processed nut 7. The internal position of the fixed seat 6 corresponding to the through-hole 8 is elastically connected to the sliding column 11 by the fixing frame 9 and the extrusion spring 10. The upper end of the sliding column 11 is fixedly connected with a synchronization block 12 and a prismatic extrusion block 13 in sequence. The extrusion block 13 is used to extrude and deform the thread through the two opposite side edges. A threaded guide groove 14 is opened in the through-hole 8. The elastic telescopic member 1 is provided in the through-hole 8. 5 is connected to a rotating ring 16 that slides in the guide groove 14. The bottom of the rotating ring 16 is fixedly connected to an L-shaped pull rod 17 that extends to the bottom of the synchronous block 12. A sliding ring 18 is elastically connected to the inner side of the rotating ring 16 for vertical sliding. An arc-shaped positioning block 19 is fixedly connected to the surface of the sliding ring 18. The positioning block 19 is used to dock with the threaded opening position of the processing nut 7. The bottom of the sliding ring 18 is fixedly connected to a synchronization rod 20 that passes through the synchronization block 12. When the synchronization rod 20 rotates, it drives the extrusion block 13 to rotate synchronously through the synchronization block 12. In the process of tapping the processing nut 7, it is necessary to first clamp the processing nut 7 to the position corresponding to the through-hole 8 on the surface of the fixing seat 6 through the clamping mechanism. When the processing nut 7 is placed, the positioning block 19, the sliding ring 18 and the extrusion block 13 are squeezed and moved downward at the same time. The positioning block 19 fits with the bottom of the processing nut 7. Then the moving arm 3 drives the tap 5 to move above the processing nut 7 and then moves downward. Then the tap 5 taps the processing nut 7. When the end of the tap 5 passes through the processing nut 7 and moves into the through-hole 8, the end of the tap 5 pushes the extrusion block 13, the synchronous block 12 and the sliding column 11 to move downward synchronously, and the extrusion spring 10 is squeezed and compressed. Then, when the synchronous block 12 moves When the tap 5 moves to the position of the pull rod 17, the pull rod 17 is pushed to move downward synchronously with the rotating ring 16. The rotating ring 16 rotates and moves downward under the action of the guide groove 14. The sliding ring 18, the synchronous rod 20 and the synchronous block 12 rotate synchronously under the drive of the rotating ring 16. The synchronous block 12 drives the extrusion block 13 to rotate together. When the extrusion block 13 rotates, the position of the side edge of the extrusion block 13 used for extrusion molding changes, and the sliding ring 18 can slide elastically up and down, so that the positioning block 19 can maintain contact with the bottom of the processing nut 7. Subsequently, when the tap 5 moves upward, the extrusion block 13, the rotating ring 16 and the sliding ring 18 move upward, and the positioning block 19 is guided by the rotating ring 16 and the guide groove 14. The tool 16 is used to rotate along the bottom of the processing nut 7. When the positioning block 19 moves to the opening position of the bottom thread of the processing nut 7, the positioning block 19 is blocked by the tap 5, and the rotating ring 16 remains stationary. Subsequently, when the tap 5 moves out of the inner side of the processing nut 7, the positioning block 19 can move along the opening position of the bottom of the inner thread of the processing nut 7 to the inner side of the thread and engage with the thread, so that the position where the extrusion block 13 extrudes and deforms the processing nut 7 can be automatically adjusted according to the different opening positions of the inner thread of the processing nut 7, ensuring that the deformation processing position of the inner thread of the processing nut 7 by the extrusion block 13 can avoid the opening position of the thread, avoiding the deformation processing of the inner thread of the processing nut 7 by the extrusion block 13 The position of the processing nut 7 cannot be changed. During the long processing, the thread opening position of the processing nut 7 is likely to be at the side edge position of the extrusion block 13. The thread after extrusion and deformation cannot match and mesh with the bolt thread, affecting the assembly of the processing nut 7 and reducing the product qualification rate. Subsequently, after the tap 5 is moved out of the inner side of the processing nut 7, the extrusion block 13 extrude and deform the inner thread of the processing nut 7 under the action of the extrusion spring 10. The tapping and thread deformation processing of the processing nut 7 are carried out continuously, and there is no need to repeatedly disassemble and transfer the processing nut 7, which simplifies the workers' operation, reduces the workload, improves the processing efficiency, and can reduce the errors caused by multiple disassembly and positioning, thereby improving the qualification rate.

[0021] As a further embodiment of the present invention, the clamping mechanism includes a plurality of clamping blocks 21, each of which elastically slides on the surface of the fixing seat 6 through a slide groove 22. The plurality of clamping blocks 21 are used to clamp and fix the side edges and corners of the processing nut 7 from different directions. During the process of tapping the processing nut 7, the processing nut 7 is first placed on the inner side of multiple clamping blocks 21 on the surface of the fixing seat 6, and then the clamping blocks 21 clamp and fix the side edges and corners of the processing nut 7 from multiple directions at the same time, so that the processing nut 7 can remain stable during the tapping process, thereby ensuring the processing effect of the thread.

[0022] During the tapping process of the processing nut 7, the processing nut 7 is repeatedly disassembled and assembled, which is cumbersome and time-consuming. As a further solution of the present invention, the slide groove 22 passes through the fixed seat 6, and the upper end of the clamping block 21 is inclined on the side away from the processing nut 7. The bottom of the movable arm 3 is fixedly connected to the position corresponding to the clamping block 21 with a push rod 23 with an inclined bottom. The push rod 23 is used to push the clamping block 21 to clamp the processing nut 7, and the bottom of the push rod 23 extends below the tap 5. In the process of tapping the processing nut 7, it is first necessary to place the processing nut 7 between the multiple clamping blocks 21 on the surface of the fixing seat 6. Then, when the moving arm 3 drives the tap 5 and the pushing rod 23 to move above the processing nut 7 and then move downward, the bottom of the pushing rod 23 first contacts the clamping block 21 and pushes the clamping block 21 to clamp the processing nut 7. Then, the pushing rod 23 moves to the inside of the fixing seat 6 through the slide groove 22, and the tap 5 can tap the processing nut 7 normally. This device enables the processing nut 7 to be automatically clamped before tapping, and there is no need for manual clamping of the processing nut 7, which reduces the time for workers to disassemble and assemble and improves processing efficiency.

[0023] During the tapping process of the processing nut 7, the extrusion block 13 is pushed downward by the tap 5, and the extrusion spring 10 is squeezed and contracted. When the tap 5 moves upward, the extrusion block 13 will move upward under the push of the extrusion spring 10, and the extrusion force of the extrusion block 13 on the processing nut 7 is relatively small. As a further solution of the present invention, a Z-shaped limiting rod 24 with inclined surfaces at both ends is elastically and slidably connected inside the fixing seat 6. The upper end of the limiting rod 24 is below the slide groove 22, and the lower end of the limiting rod 24 extends to the bottom of the fixing frame 9. The lower end of the limiting rod 24 is retractable, and an annular limiting groove 25 is provided on the surface of the sliding column 11. In the process of tapping the processing nut 7, when the moving arm 3 drives the tap 5 and the pushing rod 23 to move upward, the pushing rod 23 first passes through the sliding groove 22 and moves to the inside of the fixed seat 6, and the pushing rod 23 squeezes the limiting rod 24 to move to the side close to the sliding column 11. The end of the limiting rod 24 contacts the surface of the sliding column 11 and is squeezed and contracted. Subsequently, after the tap 5 taps the processing nut 7 and passes through the processing nut 7, the tap 5 pushes the extrusion block 13, the synchronization block 12 and the sliding column 11 to move downward. When the limiting groove 25 moves to the end position of the limiting rod 24, the end of the limiting rod 24 extends and moves into the limiting groove 25 to limit the sliding column 11. Subsequently, when the tap 5 and the pushing rod 23 move upward, the thread is cut off. The cone 5 first moves out of the inner side of the processing nut 7. When the bottom of the push rod 23 passes the upper end of the limit rod 24 and moves to the inside of the slide groove 22, the limit rod 24 moves to the side away from the sliding column 11 under the action of the spring. The bottom of the limit rod 24 moves out of the limit groove 25 to release the limit on the sliding column 11. The sliding column 11, the synchronous block 12 and the extrusion block 13 move toward the processing nut 7 under the push of the extrusion spring 10. The extrusion block 13 can extrude and deform the thread inside the processing nut 7. Limiting the sliding column 11 can enable the extrusion spring 10 to drive the sliding column 11 to pop out after being released from compression, thereby increasing the extrusion force of the extrusion block 13 on the processing nut 7 and ensuring the extrusion force on the thread of the processing nut 7.

[0024] During the tapping process of the nut 7, the extrusion spring 10 is connected to the bottom of the fixing frame 9 to affect the rotation of the synchronization block 12. As a further solution of the present invention, the bottom of the inner side of the fixing frame 9 is rotatably connected to the rotating disk 26, the bottom of the extrusion spring 10 is connected to the rotating disk 26, and the bottom of the synchronization rod 20 is retractable and connected to the rotating disk 26; During the process of tapping the nut 7, when the synchronization rod 20 drives the synchronization block 12 and the extrusion spring 10 to rotate, the rotating disk 26 rotates synchronously driven by the extrusion spring 10, ensuring that the extrusion block 13 can remain stable after rotation, avoiding the extrusion spring 10 from being unable to rotate with the fixing frame 9, thereby affecting the rotation angle of the extrusion block 13.

[0025] During the tapping process of the processing nut 7, the degree of extrusion of the processing nut 7 by the extrusion block 13 cannot be controlled, and excessive extrusion is likely to occur. As a further solution of the present invention, a limit block 27 with an adjustable length is fixedly connected to the bottom of the fixing frame 9, and a blocking ring 28 is fixedly connected to the surface of the sliding column 11; During the process of tapping the nut 7, the length of the limit block 27 is adjusted before processing. Then, when the extrusion block 13, the synchronization block 12 and the sliding column 11 extrude and deform the thread under the push of the extrusion spring 10, the limit block 27 can limit the sliding column 11 and the extrusion block 13 through the blocking ring 28, thereby controlling the depth of the extrusion thread of the extrusion block 13 to avoid excessive extrusion.

[0026] During the tapping process of the processing nut 7, when the extrusion block 13 impacts and extrudes the processing nut 7, the processing nut 7 is easily moved out of the inner side of the clamping block 21 under the impact of the extrusion block 13. As a further solution of the present invention, a blocking block 29 is elastically and slidably connected to the surface of the clamping block 21. The blocking block 29 is used to block the processing nut 7 in the up and down directions, and the end of the blocking block 29 is an inclined surface; During the process of tapping the processing nut 7, when the clamping block 21 clamps the processing nut 7, the blocking block 29 can move to the top of the processing nut 7 to block the processing nut 7. Then, when the extrusion block 13 extrude the thread of the processing nut 7, the blocking block 29 blocks the processing nut 7 to keep the processing nut 7 fixed, preventing the processing nut 7 from moving out of the inner side of the clamping block 21 under the impact of the extrusion block 13, affecting the extrusion deformation of the thread.

[0027] During the tapping process of the processing nut 7, after the processing nut 7 is placed on the surface of the fixing seat 6, the corner position of the processing nut 7 cannot be accurately aligned with the clamping block 21. As a further solution of the present invention, a plurality of limiting blocks 30 are fixedly connected between the plurality of clamping blocks 21 corresponding to the surface of the fixing seat 6. The limiting blocks 30 are used to limit the positioning of the processing nut 7 before the clamping blocks 21 clamp the processing nut 7. During the process of tapping the processing nut 7, the processing nut 7 is placed inside the multiple limiting blocks 30 on the surface of the fixing seat 6 and pressed, so that the multiple limiting blocks 30 limit the processing nut 7 and locate the position of the processing nut 7 to ensure that the subsequent clamping block 21 accurately clamps the processing nut 7.

[0028] During the tapping process of the nut 7, the tap 5 pushes the extrusion block 13 downward, and the extrusion block 13 rotates under the drive of the synchronization block 12, the synchronization rod 20, the sliding ring 18, and the rotating ring 16. The direct contact between the tap 5 and the extrusion block 13 affects the normal rotation of the extrusion block 13. As a further embodiment of the present invention, the upper end of the extrusion block 13 is rotatably connected to a rotating block 31. During the process of tapping the nut 7, the tap 5 pushes the extrusion block 13 to move downward, and the bottom thereof contacts the rotating block 31. When the extrusion block 13 rotates, the rotating block 31 maintains contact with the bottom of the tap 5, and the extrusion block 13 can rotate normally, thereby preventing the friction force when the tap 5 directly contacts the extrusion block 13 from affecting the normal rotation of the extrusion block 13.

[0029] During the tapping process of the nut 7, the chips generated during the processing fall onto the surface of the synchronization block 12 through the opening 8. As a further solution of the present invention, a guiding inclined surface 32 is provided at the upper edge of the synchronization block 12; During the process of tapping the nut 7, some debris generated by the tap 5 when tapping the nut 7 will fall onto the top of the synchronization block 12 through the through opening 8. The guiding slope 32 above the synchronization block 12 can guide the metal debris to move to the outside of the synchronization block 12, thereby preventing the metal debris on the surface of the synchronization block 12 from accumulating during a long period of processing. When the synchronization block 12 moves upward rapidly subsequently, the metal debris will be pushed upward and thrown into the air, causing certain harm to the human body.
