Description

Technical Field

[0001] This invention relates to the field of tapping device technology, specifically to a tapping device for wear-resistant and anti-slip hexagonal copper nuts used in photovoltaic fastening. Background Technology

[0002] The core function of a nut is as a fastener, which connects and fixes mechanical parts through thread engagement with a bolt. Its applications cover almost all fields involving mechanical structures, including industrial manufacturing, construction engineering, transportation, and home life.

[0003] In the current technology for tapping hexagonal copper nuts, the excellent ductility (elongation after fracture ≥15%) and low hardness (≤120HB) of copper alloys are often utilized to perform thread deformation processing after tapping to improve their anti-loosening and wear resistance. However, after tapping the copper nut, it needs to be disassembled and transferred to other stations before thread deformation processing can be performed. Multiple clamping and reassembly result in a lengthy process chain, increased labor intensity for workers, and reduced processing efficiency due to positioning errors. Furthermore, during the thread deformation processing of copper nuts, the position of the extrusion block that extrudes and deforms the thread is usually influenced by the placement of the copper nut and the cutting direction of the machining tool, which 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 bolt threads cannot accurately match and mesh, resulting in thread misalignment or jamming, which affects the normal assembly of the copper nut. Summary of the Invention

[0004] The purpose of this invention is to provide a tapping device for wear-resistant and anti-slip hexagonal copper nuts used for photovoltaic fastening, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant and anti-slip hexagonal copper nut tapping device for photovoltaic fastening, comprising a processing table, a movable arm, and a fixed base fixedly installed on the processing table;

[0006] The fixed base surface is provided with a clamping mechanism for clamping the processed nut. The fixed base surface has an opening corresponding to the position of the processed nut. Inside the fixed base, corresponding to the position of the opening, a sliding column is elastically slidably connected to the compression spring via a fixed frame. A synchronizing block and a prism-shaped compression block are sequentially fixedly connected to the upper end of the sliding column. The compression block is used to compress and deform the thread through two opposing side edges. A threaded guide groove is provided inside the opening. A rotating ring that slides in the guide groove is connected to the opening via an elastic telescopic component. An L-shaped pull rod extending below the synchronizing block is fixedly connected to the bottom of the rotating ring. A sliding ring is elastically slidably connected to the inner side of the rotating ring. An arc-shaped positioning block is fixedly connected to the surface of the sliding ring. The positioning block is used to mate with the thread opening position of the processed nut. A synchronizing rod penetrating the synchronizing block is fixedly connected to the bottom of the sliding ring. When the synchronizing rod rotates, it drives the compression block to rotate synchronously through the synchronizing block.

[0007] As a further embodiment of the present invention, the clamping mechanism includes a plurality of clamping blocks, all of which slide elastically on the surface of the fixed base via a sliding groove. The plurality of clamping blocks are used to clamp and fix the sides and corners of the processed nut from different directions.

[0008] As a further embodiment of the present invention, the groove passes through the fixed base, the upper end of the clamping block is inclined on the side away from the processing nut, and a push rod with an inclined bottom is fixedly connected to the bottom of the moving arm corresponding to the position of the clamping block. The push rod is used to push the clamping block to clamp the processing nut, and the bottom of the push rod extends to below the tap.

[0009] As a further embodiment of the present invention, the fixed base is internally elastically slidably connected with a Z-shaped limiting rod with both ends being inclined surfaces. The upper end of the limiting rod is located below the sliding groove, the lower end of the limiting rod extends to the lower part of the fixed frame, and the lower end of the limiting rod is retractable. An annular limiting groove is formed on the surface of the sliding column.

[0010] As a further embodiment of the present invention, a rotating disk is rotatably connected to the bottom inner side of the fixing frame, the bottom of the compression spring is connected to the rotating disk, and the bottom of the synchronizing rod is retractable and connected to the rotating disk.

[0011] As a further embodiment of the present invention, an adjustable length limiting block is fixedly connected to the bottom of the fixing frame, and a blocking ring is fixedly connected to the surface of the sliding column.

[0012] As a further embodiment of the present invention, a blocking block is elastically slidably connected to the surface of the clamping block, the blocking block being used to block the processing nut in the vertical direction, and the end of the blocking block being a bevel.

[0013] As a further aspect of the present invention, a plurality of limiting blocks are fixedly connected to the surface of the fixed base corresponding to the plurality of clamping blocks. The limiting blocks are used to restrict and position the machining nut before the clamping blocks clamp the machining nut.

[0014] As a further embodiment of the present invention, a rotating block is rotatably connected to the upper end of the extrusion block.

[0015] As a further embodiment of the present invention, a guide slope is provided at the upper edge of the synchronization block.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In the process of tapping a nut, this invention uses a positioning block to position the opening at the bottom of the internal thread of the nut. This allows the extrusion block to automatically adjust the position of the extrusion block's deformation of the nut according to the different opening positions of the internal thread. This ensures that the deformation of the nut's internal thread by the extrusion block avoids the opening position of the thread. It also prevents the nut's thread opening from being located at the side edge of the extrusion block during prolonged processing, which can lead to the deformed thread not engaging with the bolt thread, affecting the assembly of the nut and reducing the product qualification rate.

[0018] In the process of tapping a nut, the present invention first places the nut inside multiple clamping blocks on the surface of the fixed base. Then, the clamping blocks clamp and fix the sides and corners of the nut from multiple directions simultaneously, so that the nut can remain stable during the tapping process and ensure the thread processing effect.

[0019] In the process of tapping a nut, the present invention first places the nut between multiple clamping blocks on the surface of a fixed base. Then, the moving arm moves the tap and the push rod above the nut and then moves downward. The bottom of the push rod first contacts the clamping block and pushes the clamping block to clamp the nut. Then, the push rod moves through the slide groove into the fixed base, and the tap can tap the nut normally. This device can automatically clamp the nut before tapping, eliminating the need for manual clamping, reducing the time for workers to disassemble and assemble, and improving processing efficiency.

Detailed Implementation

[0037] Please see Figures 1-16 The present invention provides a technical solution: a wear-resistant and anti-slip hexagonal copper nut tapping device for photovoltaic fastening, comprising a base 1, a processing table 2, a moving arm 3, a cooling pipe 4, a tap 5, and a fixed seat 6 that is fixedly installed on the surface of the processing table 2 by a clamp and is hollow inside;

[0038] The surface of the fixed base 6 is provided with a clamping mechanism for clamping the machining nut 7. A through-hole 8 is opened on the surface of the fixed base 6 corresponding to the position of the machining nut 7. Inside the fixed base 6, corresponding to the position of the through-hole 8, a sliding column 11 is elastically slidably connected vertically to the compression spring 10 via a fixed bracket 9. A synchronizing block 12 and a prism-shaped compression block 13 are sequentially fixedly connected to the upper end of the sliding column 11. The compression block 13 is used to compress and deform the thread through its two opposing side edges. A threaded guide groove 14 is opened inside the through-hole 8. An elastic telescopic member 1... 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 synchronizing block 12. The inner side of the rotating ring 16 is elastically slidably connected to a sliding ring 18. The surface of the sliding ring 18 is fixedly connected to an arc-shaped positioning block 19. The positioning block 19 is used to mate with the thread opening position of the machining nut 7. The bottom of the sliding ring 18 is fixedly connected to a synchronizing rod 20 that passes through the synchronizing block 12. When the synchronizing rod 20 rotates, it drives the pressing block 13 to rotate synchronously through the synchronizing block 12.

[0039] During the tapping process of the machining nut 7, the machining nut 7 needs to be clamped and fixed to the corresponding position of the through hole 8 on the surface of the fixed base 6 by the clamping mechanism. When the machining nut 7 is placed, the pressing positioning block 19, the sliding ring 18 and the pressing block 13 move downward at the same time, and the positioning block 19 is in contact with the bottom of the machining nut 7. Then the moving arm 3 drives the tap 5 to move above the machining nut 7 and then moves downward. Then the tap 5 taps the machining nut 7. When the end of the tap 5 passes through the machining nut 7 and moves into the through hole 8, the end of the tap 5 pushes the pressing block 13, the synchronizing block 12 and the sliding column 11 to move downward synchronously. The pressing spring 10 is compressed. Then when the synchronizing block 12 moves... When the pull rod 17 is moved to position 17, it pushes the pull rod 17 and the rotating ring 16 to move downwards synchronously. The rotating ring 16 rotates and moves downwards under the action of the guide groove 14. The sliding ring 18, the synchronizing rod 20, and the synchronizing block 12 rotate synchronously under the drive of the rotating ring 16. The synchronizing 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 accordingly. The sliding ring 18 can slide up and down elastically, so that the positioning block 19 can keep in contact with the bottom of the machining nut 7. Then, when the tap 5 moves upwards, the extrusion block 13, the rotating ring 16, and the sliding ring 18 move upwards. The positioning block 19 moves upwards under the guidance of the rotating ring 16 and the guide groove 14. The locating block 19 rotates along the bottom of the machining nut 7. When it moves to the opening position of the thread at the bottom of the machining nut 7, the locating block 19 is blocked by the tap 5, and the rotating ring 16 remains stationary. Subsequently, after the tap 5 moves out of the inner side of the machining nut 7, the locating block 19 can move along the opening position of the bottom of the internal thread of the machining nut 7 to the inner side of the thread and engage with the thread. This allows the extrusion block 13 to automatically adjust the position of the extrusion block 13 in extruding and deforming the machining nut 7 according to the different opening positions of the internal thread of the machining nut 7. This ensures that the extrusion block 13 can avoid the opening position of the thread and prevent the extrusion block 13 from deforming the internal thread of the machining nut 7. The position cannot be changed. During long-term processing, the thread opening of the nut 7 may be located at the side edge of the extrusion block 13. The extruded and deformed thread cannot match the bolt thread, affecting the assembly of the nut 7 and reducing the product qualification rate. Subsequently, after the tap 5 is moved out of the inner side of the nut 7, the extrusion block 13 extrudes and deforms the inner thread of the nut 7 under the action of the extrusion spring 10. The tapping and thread deformation of the nut 7 are carried out continuously, without the need for repeated disassembly and relocation of the nut 7. This simplifies the operation of workers, reduces workload, improves processing efficiency, and reduces the errors caused by multiple disassembly and repositioning, thereby improving the qualification rate.

[0040] As a further embodiment of the present invention, the clamping mechanism includes a plurality of clamping blocks 21, which are all elastically slidable on the surface of the fixed base 6 through the sliding groove 22. The plurality of clamping blocks 21 are used to clamp and fix the side and corner positions of the processed nut 7 from different directions.

[0041] During the tapping process of the machining nut 7, the machining nut 7 is first placed inside the multiple clamping blocks 21 on the surface of the fixed base 6. Then, the clamping blocks 21 clamp and fix the sides and corners of the machining nut 7 from multiple directions at the same time, so that the machining nut 7 can remain stable during the tapping process and ensure the machining effect of the thread.

[0042] During the tapping process of the machining nut 7, the repeated disassembly and assembly of the machining nut 7 is tedious and time-consuming. As a further solution of the present invention, the slide groove 22 passes through the fixed seat 6, the upper end of the clamping block 21 is inclined on the side away from the machining nut 7, and the bottom of the moving arm 3 is fixedly connected to the position of the clamping block 21 with a push rod 23 having an inclined bottom. The push rod 23 is used to push the clamping block 21 to clamp the machining nut 7, and the bottom of the push rod 23 extends to below the tap 5.

[0043] During the tapping process of the nut 7, the nut 7 is first placed between multiple clamping blocks 21 on the surface of the fixed base 6. Then, the moving arm 3 moves the tap 5 and the push rod 23 to above the nut 7 and then moves downward. The bottom of the push rod 23 first contacts the clamping block 21 and pushes the clamping block 21 to clamp the nut 7. Then, the push rod 23 moves into the fixed base 6 through the slide groove 22, and the tap 5 can tap the nut 7 normally. This device enables the nut 7 to be automatically clamped before tapping, eliminating the need for manual clamping of the nut 7, reducing the time for workers to disassemble and assemble, and improving processing efficiency.

[0044] During the tapping process of the nut 7, when the extrusion block 13 is pushed downward by the tap 5, the extrusion spring 10 is compressed and contracted. When the tap 5 moves upward, the extrusion block 13 moves upward under the push of the extrusion spring 10. The extrusion block 13 exerts a relatively small extrusion force on the nut 7. As a further embodiment of the present invention, the fixed base 6 is elastically slidably connected with a Z-shaped limiting rod 24 with both ends being inclined. The upper end of the limiting rod 24 is located below the sliding groove 22, and the lower end of the limiting rod 24 extends to the lower end of the fixed frame 9. The lower end of the limiting rod 24 is telescopic. The sliding column 11 has an annular limiting groove 25 on its surface.

[0045] During the tapping process of the nut 7, when the moving arm 3 drives the tap 5 and the push rod 23 to move upward, the push rod 23 first passes through the slide groove 22 and moves into the fixed seat 6. The push rod 23 then presses the limiting rod 24 and moves it closer to the sliding column 11. The end of the limiting rod 24 contacts the surface of the sliding column 11 and is compressed and contracted. Subsequently, after the tap 5 taps the nut 7, it pushes the extrusion block 13, the synchronizing block 12, and the sliding column 11 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. Then, when the tap 5 and the push rod 23 move upward, the tap 5 pushes the nut 7 to move downward. First, cone 5 moves out of the inner side of the machining nut 7. When the bottom of push rod 23 moves past the upper end of limit rod 24 into the slide groove 22, limit rod 24 moves away from sliding column 11 under the action of spring. The bottom of limit rod 24 moves out of limit groove 25 to release the limit on sliding column 11. Sliding column 11, synchronizing block 12 and pressing block 13 move closer to machining nut 7 under the push of pressing spring 10. Pressing block 13 can compress and deform the thread inside machining nut 7. Limiting sliding column 11 can cause pressing spring 10 to drive sliding column 11 to pop out after being released from compression, increasing the pressing force of pressing block 13 on machining nut 7 and ensuring the pressing force on the thread of machining nut 7.

[0046] During the tapping process of the machining nut 7, the compression spring 10 is connected to the bottom of the fixed frame 9, which affects the rotation of the synchronizing block 12. As a further embodiment of the present invention, a rotating disk 26 is rotatably connected to the bottom of the inner side of the fixed frame 9, the bottom of the compression spring 10 is connected to the rotating disk 26, and the bottom of the synchronizing rod 20 is retractable and connected to the rotating disk 26.

[0047] During the tapping process of the machining nut 7, when the synchronizing rod 20 drives the synchronizing block 12 and the compression spring 10 to rotate, the rotating disk 26 rotates synchronously under the drive of the compression spring 10, ensuring that the compression block 13 can remain stable after rotation, and preventing the compression spring 10 from not being able to rotate with the fixed frame 9, thereby affecting the rotation angle of the compression block 13.

[0048] During the tapping process of the machining nut 7, the degree of extrusion of the extrusion block 13 on the thread of the machining nut 7 cannot be controlled, and over-extrusion is likely to occur. As a further solution of the present invention, an adjustable length limit block 27 is fixedly connected to the bottom of the fixed frame 9, and a blocking ring 28 is fixedly connected to the surface of the sliding column 11.

[0049] During the tapping process of the nut 7, the length of the limiting block 27 is adjusted before processing. Then, when the extrusion block 13, the synchronizing block 12 and the sliding column 11 are extruded and deformed by the extrusion spring 10, the limiting 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 block 13 extruding the thread and avoiding excessive extrusion.

[0050] During the tapping process of the machining nut 7, when the extrusion block 13 impacts and extrudes the machining nut 7, the machining 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, the surface of the clamping block 21 is elastically slidably connected with a blocking block 29. The blocking block 29 is used to block the machining nut 7 in the up and down direction, and the end of the blocking block 29 is a bevel.

[0051] During the tapping process of the machining nut 7, when the clamping block 21 clamps the machining nut 7, the blocking block 29 can move above the machining nut 7 to block it. Subsequently, when the extrusion block 13 extrudes the thread of the machining nut 7, the blocking block 29 can keep the machining nut 7 fixed and prevent the machining nut 7 from moving out of the inner side of the clamping block 21 under the impact of the extrusion block 13, thus affecting the extrusion deformation of the thread.

[0052] During the tapping process of the machining nut 7, after the machining nut 7 is placed on the surface of the fixed seat 6, the corner position of the machining nut 7 cannot be accurately aligned with the clamping block 21. As a further solution of the present invention, multiple limiting blocks 30 are fixedly connected between multiple clamping blocks 21 on the surface of the fixed seat 6. The limiting blocks 30 are used to limit and position the machining nut 7 before the clamping block 21 clamps the machining nut 7.

[0053] During the tapping process of the machining nut 7, the machining nut 7 is placed inside the multiple limiting blocks 30 on the surface of the fixed base 6 and pressed down, so that the multiple limiting blocks 30 restrict the machining nut 7 and position the machining nut 7, ensuring that the subsequent clamping block 21 accurately clamps the machining nut 7.

[0054] During the tapping process of the machining nut 7, when the tap 5 pushes the extrusion block 13 to move downward, the extrusion block 13 rotates under the drive of the synchronizing block 12, synchronizing rod 20, sliding ring 18 and rotating ring 16. Direct contact between the tap 5 and the extrusion block 13 will affect the normal rotation of the extrusion block 13. As a further solution of the present invention, the upper end of the extrusion block 13 is rotatably connected to the rotating block 31.

[0055] During the tapping process of the nut 7, when the tap 5 pushes the pressing block 13 downward, its bottom contacts the rotating block 31. When the pressing block 13 rotates, the rotating block 31 remains in contact with the bottom of the tap 5, so that the pressing block 13 can rotate normally. This avoids the friction force from the tap 5 directly contacting the pressing block 13, which would affect the normal rotation of the pressing block 13.

[0056] During the tapping process of the machining nut 7, the machining debris falls onto the surface of the synchronizing block 12 through the through-hole 8. As a further embodiment of the present invention, a guide slope 32 is provided at the upper edge of the synchronizing block 12.

[0057] During the tapping process of the nut 7, some of the chips generated by the tap 5 will fall through the through-hole 8 onto the top of the synchronizing block 12. The guide slope 32 on the top of the synchronizing block 12 can guide the metal chips to move outward from the synchronizing block 12, preventing the metal chips on the surface of the synchronizing block 12 from accumulating during long-term processing. When the synchronizing block 12 moves upward rapidly in the future, it will push the metal chips upward and throw them into the air, causing certain harm to the human body.
