[0014] The welding method of the welding equipment for the production of the anvil seat assembly includes the following specific steps: Step 1, workpiece loading: Place the anvil seat body into the placing seat, push the rotating assembly horizontally through the first electric push rod, push the placing seat into the card slot in the welding seat to position the anvil seat body, clamp the connecting shaft with two first arc-shaped clamping blocks arranged on the electric claw, push the vertical rod horizontally through the second electric push rod, when the connecting shaft coincides with the center of the anvil seat body, the limiting block fixed on the vertical rod abuts against the welding seat, then the vertical rod stops moving, and the servo electric cylinder fixed on the vertical rod drives the support plate to move downward, so that the lower end of the connecting shaft abuts tightly against the surface of the anvil seat body; Step 2, workpiece positioning: The end of the second electric push rod continues to move to push the U-shaped abutting frame horizontally, so that the U-shaped abutting frame abuts against the first abutting wedge blocks fixed below the two mounting brackets, and the two mounting brackets drive the second arc-shaped clamping blocks to move horizontally to abut against the surface of the connecting shaft to position it; Step 3: Rotary welding of the workpiece. Align the laser welding head of the laser welding equipment with the connection between the connecting shaft and the body of the nail holder. When the end of the second electric push rod continues to move, the rack drives the meshing gear to rotate. At the same time, the rotating shaft drives the nail holder body on the placement seat to rotate. When the several first rotating rollers rotatably connected to the first arc-shaped clamp block and the several second rotating rollers rotatably connected to the second arc-shaped clamp block cooperate, the nail holder body and the connecting shaft rotate synchronously, facilitating the uniform distribution of the weld seams on the nail holder body and the connecting shaft with the laser welding head in a fixed position. Step 4: Cleaning of the weld seam of the workpiece. During the horizontal movement of the vertical rod, it drives the C-shaped block, the third sliding rod, the cleaning bracket, and the cleaning block to move horizontally synchronously, enabling the cleaning block to contact the surface of the weld seam. As the workpiece rotates, the cleaning block can clean the welding stains on the surface of the weld seam. At the same time, when the several abutting rods fixed on the placement seat rotate, they can intermittently abut against the second abutting wedge block, causing the second abutting wedge block to move up and down reciprocally and abut against the cleaning bracket. The cleaning bracket drives the cleaning block to reciprocally move to clean the weld seam stains. Step 5: Self-cleaning of the cleaning block. After the cleaning of the workpiece weld seam is completed, the telescopic end of the second electric push rod retracts. The second arc-shaped clamp releases the positioning of the connecting shaft. At the same time, the electric claw drives the first arc-shaped clamp to move and release the clamping of the connecting shaft, enabling the first electric push rod to take the workpiece on the placement seat away from the welding seat. At the same time, the hollow rectangular rod releases the abutment with the placement seat, allowing the nozzle to move under the cleaning block for water spraying and flushing. After the flushing is completed, the telescopic end of the second electric push rod continues to retract, causing the abutting strip to release the abutment against the third abutting wedge block. The scraping plate frame slides on the sliding bracket under the action of the elastic force of the eighth spring, and the moving scraping plate frame can scrape the sewage on the cleaning block, achieving the purpose of self-cleaning of the cleaning block.

[0015] The present invention has the following beneficial effects: 1. The welding equipment for producing the anvil seat assembly can conveniently place the anvil seat body through the placement seat, and can push the placement seat into the slot in the welding seat through the first electric push rod, so as to achieve the purpose of positioning the welding position of the anvil seat body, and can conveniently clamp and fix the connecting shaft through the two first arc-shaped clamping blocks arranged on the electric clamping claws, and the second electric push rod pushes the vertical pole to move horizontally, so as to make the connecting shaft coincide with the center of the circle of the anvil seat body, and at the same time, the limit block fixed on the vertical pole abuts on the welding seat, and can achieve the purpose of positioning the connecting shaft after the center of the circle coincides, and can drive the support through the servo electric cylinder fixed on the vertical pole The support plate moves downward, causing the lower end of the connecting shaft to fit tightly against the surface of the pin holder body, thereby improving the firmness of the welding end surface fit. When the second electric push rod pushes the 匚-shaped contact frame to move horizontally, the 匚-shaped contact frame is caused to come into contact with the first contact wedges fixed below the two mounting frames, thereby achieving the purpose of the two mounting frames driving the second arc-shaped clamping block to move horizontally against the surface of the connecting shaft for positioning, further improving the stability of the position of the connecting shaft during welding, and saving time, labor and convenience in the welding positioning process of the workpiece. At the same time, the connecting shaft is not easily affected by external forces during the welding process, thereby improving the welding quality and welding accuracy. 2. In the welding equipment for the production of the dowel seat assembly, when the telescopic end of the second electric push rod continues to move, the 匚-shaped abutment frame can drive the rack to move horizontally, which is convenient for the gear to rotate. At the same time, the rotating shaft drives the dowel seat body on the placement seat to rotate synchronously. Through the cooperation of the first rotating rollers rotatably connected to the first arc-shaped clamping block and the second rotating rollers rotatably connected to the second arc-shaped clamping block, the dowel seat body and the connecting shaft can be rotated synchronously, so that the laser welding head can be kept in a fixed position to facilitate the even distribution of the weld on the dowel seat body and the connecting shaft, thereby reducing the dead angle of welding and improving the welding quality and welding efficiency.

[0016] 3. The welding equipment for the production of the nail support assembly can achieve the purpose of driving the 匚-shaped block, the third sliding rod, the cleaning bracket and the cleaning block to move synchronously during horizontal movement through the vertical rod, so that the cleaning block can be pressed against the weld of the workpiece. As the workpiece rotates, it is convenient to clean the welding stains on the weld surface, thereby improving the quality of welding. At the same time, the plurality of abutment rods fixed on the placement seat can intermittently abut with the second abutment wedge block when rotating, so that the second abutment wedge block moves back and forth up and down and abuts against the cleaning bracket, which facilitates the cleaning bracket to drive the cleaning block to move back and forth, thereby further improving the cleaning effect of welding stains. The nozzle arranged on the hollow rectangular rod can be used to rinse the stains on the cleaning block after the workpiece is unloaded. The sliding bracket fixed on the cleaning bracket is conveniently connected to the scraper bracket for sliding. When the scraper bracket can automatically move horizontally on the sliding bracket under the action of the elastic force of the eighth spring, the sewage on the cleaning block can be automatically scraped off, thereby facilitating the self-cleaning of the cleaning block, reducing surface stains, and facilitating the cleaning of the weld of the next workpiece.

After that, the first electric push rod 4 stops working, and the purpose of positioning the welding position of the anvil seat body 6 can be achieved. The two first arc-shaped clamping blocks 121 are driven to approach each other by the electric clamping claw 12, which is convenient for clamping the connecting shaft 13. The second electric push rod 7 pushes the vertical rod 8 to move horizontally. When the center of the connecting shaft 13 coincides with the center of the anvil seat body 6, the limit block 14 fixed on the vertical rod 8 also abuts against the welding seat 2 at the same time, thereby achieving the purpose of limiting the vertical rod 8.

[0033] In order to improve the welding efficiency and quality of workpieces, refer to Figures 1 - 4When the telescopic end of the second electric push rod 7 continues to move, the purpose of driving the rack 404 to move horizontally by the U-shaped abutting frame 20 can be achieved, which is convenient for driving the gear 403 in the rotating assembly to rotate, prompting the rotating shaft 402 to rotate on the rotating frame 401, and simultaneously driving the placing seat 5 to rotate. When the cooperation of a plurality of first rotating rollers 24 rotatably connected to the first arc-shaped clamp block 121 and a plurality of second rotating rollers 25 rotatably connected to the second arc-shaped clamp block 15 is used, the purpose that the nail abutting seat body 6 and the connecting shaft 13 can rotate synchronously can be achieved, so that the position of the welding head of the laser welding device remains unchanged, and it is convenient for the weld seams to be evenly distributed on the nail abutting seat body 6 and the connecting shaft 13, reducing the welding dead angle and improving the welding quality and welding efficiency.

[0034] Embodiment 3 is an improvement made on the basis of Embodiment 2. Specifically, please refer to Figures 1 - 8 , there is a U-shaped block 26 arranged above the welding seat 2. A third sliding rod 27 is fixed on the U-shaped block 26. The third sliding rod 27 is elastically connected to the vertical rod 8 through a fourth spring 28. Two fourth sliding rods 29 are fixed inside the U-shaped block 26. A cleaning bracket 30 is slidably connected to the fourth sliding rods 29. The cleaning bracket 30 is elastically connected to the U-shaped block 26 through a fifth spring 31. One end of the cleaning bracket 30 is fixed with a cleaning block 32.

[0035] A second abutting wedge block 33 is arranged below the cleaning bracket 30. The second abutting wedge block 33 is elastically connected to the second abutting wedge block 33 through a sixth spring 34. A plurality of equally spaced abutting rods 35 are fixed on the circumferential surface of the placing seat 5.

[0036] A fifth sliding rod 36 is fixed on the welding seat 2. A hollow rectangular rod 37 is slidably connected to the fifth sliding rod 36. The hollow rectangular rod 37 is elastically connected to the welding seat 2 through a seventh spring 38. One end of the hollow rectangular rod 37 abuts against the placing seat 5. A nozzle 39 is fixed on the hollow rectangular rod 37.

[0037] A sliding bracket 40 is fixed on the cleaning bracket 30. One end of the cleaning block 32 is provided with a scraping bracket 41. The upper end of the scraping bracket 41 is elastically connected to the sliding bracket 40 through an eighth spring 42. A third abutting wedge block 43 is fixed on the scraping bracket 41. A resisting strip 44 is fixed on the mounting bracket 16.

[0038] On the surface of the workpiece weld, stains are likely to appear due to the influence of welding parameters, welding processes, and welding materials. It is necessary to clean it to improve the welding quality of the workpiece. The vertical rod 8 can drive the U-shaped block 26, the third sliding rod 27, the cleaning bracket 30, and the cleaning block 32 to move synchronously during horizontal movement. Through the cooperation of the fourth spring 28 on the third sliding rod 27, the cleaning block 32 can always be pressed against the weld of the workpiece. As the workpiece rotates, it is convenient to clean the welding stains on the weld surface, which can improve the welding quality. To improve the cleaning effect, refer to Figures 4 - 5 , when the plurality of abutting rods 35 fixed on the placement seat 5 rotate, they can intermittently abut against the second abutting wedge 33. The sixth spring 34 continuously stores and releases elastic force, prompting the second abutting wedge 33 to move up and down reciprocally and abut against the cleaning bracket 30, causing one end of the cleaning bracket 30 to reciprocally slide on the two fourth sliding rods 29 in the U-shaped block 26. At the same time, the fifth spring 31 continuously stores and releases elastic force, facilitating the cleaning block 32 to reciprocally move on the weld surface for cleaning, which can further improve the cleaning effect of the welding stains.

[0039] After the cleaning is completed, the surface of the cleaning block 32 needs to be self-cleaned to facilitate the cleaning of the weld of the next workpiece. Refer to Figures 2 - 7 , when the workpiece is loaded, the placement seat 5 moves horizontally and abuts against the hollow rectangular rod 37, prompting the hollow rectangular rod 37 to slide on the fifth sliding rod 36, which can hide the nozzle 39. At the same time, during the horizontal movement of the vertical rod 8, the mounting bracket 16 can drive the abutting strip 44 to move and abut against the third abutting wedge 43 fixed on the scraping bracket 41, prompting the scraping bracket 41 to move horizontally on the sliding bracket 40. At the same time, the eighth spring 42 stores elastic force. When the stains on the surface of the workpiece weld are cleaned, the telescopic end of the second electric push rod 7 retracts a certain distance, the rack 404 and the gear 403 disengage, and when the telescopic end of the second electric push rod 7 disengages from the welding seat 2, at this time, the second arc-shaped clamp 15 separates from the connecting shaft 13, and at the same time, the electric claw 12 drives the first arc-shaped clamp 121 to move to release the clamping of the connecting shaft 13, enabling the first electric push rod 4 to take the workpiece on the placement seat 5 away from the welding seat 2. When the hollow rectangular rod 37 is released from the abutment with the placement seat 5, the nozzle 39 automatically moves below the cleaning block 32. By controlling the external equipment of the nozzle through the controller, water is conveyed into the nozzle 39 for spraying and rinsing. After the rinsing is completed, the telescopic end of the second electric push rod 7 continues to retract, prompting the abutting strip 44 to release the abutment against the third abutting wedge 43, facilitating the scraping bracket 41 to slide on the sliding bracket 40 under the action of the elastic force of the eighth spring 42. At the same time, the scraping bracket 41 scrapes the sewage on the cleaning block 32 for self-cleaning. Finally, the second electric push rod 7 drives the vertical rod 8 to reset.

[0040] Embodiment 4 Please refer to Figures 1 - 8, A welding method for a welding device used in the production of an anvil assembly, comprising the following specific steps: Step 1, workpiece feeding. Place the anvil body 6 into the placement seat 5. Push the rotating assembly horizontally through the first electric push rod 4, and push the placement seat 5 into the card slot 3 in the welding seat 2 to position the anvil body 6. Clamp the connecting shaft 13 with two first arc-shaped clamping blocks 121 provided on the electric claw 12. Push the vertical rod 8 horizontally through the second electric push rod 7. When the connecting shaft 13 coincides with the center of the anvil body 6, the limiting block 14 fixed on the vertical rod 8 abuts against the welding seat 2, and then the vertical rod 8 stops moving. The servo electric cylinder 10 fixed on the vertical rod 8 drives the support plate 11 to move downward, so that the lower end of the connecting shaft 13 tightly abuts against the surface of the anvil body 6. Step 2, workpiece positioning. The end of the second electric push rod 7 continues to move to push the U-shaped abutting frame 20 horizontally, causing the U-shaped abutting frame 20 to abut against the first abutting wedge blocks 21 fixed below the two mounting frames 16. The two mounting frames 16 drive the second arc-shaped clamping blocks 15 to move horizontally and abut against the surface of the connecting shaft 13 for positioning. Step 3, workpiece rotary welding. Align the laser welding head of the laser welding device with the connection part between the connecting shaft 13 and the anvil body 6. When the end of the second electric push rod 7 continues to move, the rack 404 drives the meshing gear 403 to rotate. At the same time, the rotating shaft 402 drives the anvil body 6 on the placement seat 5 to rotate. With the cooperation of a plurality of first rotating rollers 24 rotatably connected to the first arc-shaped clamping block 121 and a plurality of second rotating rollers 25 rotatably connected to the second arc-shaped clamping block 15, the anvil body 6 and the connecting shaft 13 rotate synchronously, facilitating the uniform distribution of the weld seams on the anvil body 6 and the connecting shaft 13 with the laser welding head in a fixed position. Step 4, workpiece weld cleaning. During the horizontal movement of the vertical rod 8, it drives the U-shaped block 26, the third sliding rod 27, the cleaning bracket 30 and the cleaning block 32 to move horizontally synchronously, so that the cleaning block 32 can contact the surface of the weld seam. As the workpiece rotates, the cleaning block 32 can clean the welding stains on the surface of the weld seam. At the same time, when a plurality of abutting rods 35 fixed on the placement seat 5 rotate, they can intermittently abut against the second abutting wedge block 33, causing the second abutting wedge block 33 to move up and down reciprocally and abut against the cleaning bracket 30. The cleaning bracket 30 drives the cleaning block 32 to move reciprocally to clean the weld seam stains. Step 5, self-cleaning of the cleaning block. After the workpiece weld is cleaned, the telescopic end of the second electric push rod 7 is retracted, and the second arc-shaped clamping block 15 releases the positioning of the connecting shaft 13. At the same time, the electric clamping claw 12 drives the first arc-shaped clamping block 121 to move and release the clamping of the connecting shaft 13, so that the first electric push rod 4 takes the workpiece on the placement seat 5 away from the welding seat 2. At the same time, the hollow rectangular rod 37 releases the interference with the placement seat 5, so that the nozzle 39 moves to the bottom of the cleaning block 32 for water spraying and flushing. After the flushing is completed, the telescopic end of the second electric push rod 7 continues to retract, prompting the interference bar 44 to release the interference with the third interference wedge 43, and the scraper frame 41 slides on the sliding bracket 40 under the action of the elastic force of the eighth spring 42. The moving scraper frame 41 can scrape off the sewage on the cleaning block 32, thereby achieving the purpose of self-cleaning of the cleaning block 32.

10. The welding method of the welding equipment for producing anvil assembly according to claim 9, characterized in that: It includes the following specific steps: Step 1: Workpiece feeding. Place the nail holder body (6) into the placing seat (5). Push the rotating assembly horizontally through the first electric push rod (4) to push the placing seat (5) into the card slot (3) in the welding seat (2) to position the nail holder body (6). Clamp the connecting shaft (13) with two first arc-shaped clamping blocks (121) arranged on the electric claw (12). Push the vertical rod (8) horizontally through the second electric push rod (7). When the connecting shaft (13) coincides with the center of the nail holder body (6), the limiting block (14) fixed on the vertical rod (8) abuts against the welding seat (2), then the vertical rod (8) stops moving. The servo electric cylinder (10) fixed on the vertical rod (8) drives the support plate (11) to move downward, so that the lower end of the connecting shaft (13) tightly abuts against the surface of the nail holder body (6). Step 2: Workpiece positioning. The end of the second electric push rod (7) continues to move to push the U-shaped abutting frame (20) horizontally, causing the U-shaped abutting frame (20) to abut against the first abutting wedge blocks (21) fixed below the two mounting brackets (16). The two mounting brackets (16) drive the second arc-shaped clamping blocks (15) to move horizontally and abut against the surface of the connecting shaft (13) to position it. Step 3: Rotary welding of the workpiece. Align the laser welding head of the laser welding equipment with the connection part between the connecting shaft (13) and the anvil seat body (6). When the end of the second electric push rod (7) continues to move, the rack (404) drives the meshing gear (403) to rotate. At the same time, the rotating shaft (402) drives the anvil seat body (6) on the placing seat (5) to rotate. When several first rotating rollers (24) rotatably connected to the first arc-shaped clamp block (121) and several second rotating rollers (25) rotatably connected to the second arc-shaped clamp block (15) cooperate, the anvil seat body (6) and the connecting shaft (13) rotate synchronously, facilitating uniform distribution of the weld seams on the anvil seat body (6) and the connecting shaft (13) with the laser welding head in a fixed position; Step 4: Cleaning of the weld seams of the workpiece. During the horizontal movement of the vertical rod (8), it drives the U-shaped block (26), the third sliding rod (27), the cleaning bracket (30) and the cleaning block (32) to move horizontally synchronously, enabling the cleaning block (32) to contact the surface of the weld seam. As the workpiece rotates, the cleaning block (32) can clean the welding stains on the surface of the weld seam. At the same time, when several abutting rods (35) fixed on the placing seat (5) rotate, they can intermittently abut against the second abutting wedge block (33), causing the second abutting wedge block (33) to move up and down reciprocally and abut against the cleaning bracket (30). The cleaning bracket (30) drives the cleaning block (32) to move reciprocally to clean the weld seam stains; Step 5: Self-cleaning of the cleaning block. After the cleaning of the workpiece weld seams is completed, the telescopic end of the second electric push rod (7) retracts, the second arc-shaped clamp block (15) releases the positioning of the connecting shaft (13), and at the same time, the electric claw (12) drives the first arc-shaped clamp block (121) to move to release the clamping of the connecting shaft (13), enabling the first electric push rod (4) to take the workpiece on the placing seat (5) away from the welding seat (2). At the same time, the hollow rectangular rod (37) releases the abutment against the placing seat (5), causing the nozzle (39) to move below the cleaning block (32) for water spraying and rinsing. After the rinsing is completed, the telescopic end of the second electric push rod (7) continues to retract, causing the abutting strip (44) to release the abutment against the third abutting wedge block (43). The scraping plate frame (41) slides on the sliding bracket (40) under the action of the elastic force of the eighth spring (42). The moving scraping plate frame (41) can scrape the sewage on the cleaning block (32) to achieve the purpose of self-cleaning of the cleaning block (32).
