[0030] like Figures 1-5 The medical planing tool welding equipment shown includes a welding worktable 1, a clamping mechanism 2, and a laser welding mechanism 3. The clamping mechanism 2 is located at the top of the welding worktable 1, and the laser welding mechanism 3 is located on the outside of the clamping mechanism 2. At least three laser welding mechanisms 3 are provided.

[0031] The clamping mechanism 2 includes an upper clamping mechanism 201 and a lower clamping mechanism 202. The upper clamping mechanism 201 is used to clamp the tool bar 4, and the lower clamping mechanism 202 is used to clamp the tool head blank 203.

[0032] The laser welding mechanism 3 includes a first fixed column 301, a laser welder 302, and a high-definition camera 303. The laser welder 302 is movably mounted on the first fixed column 301, and the high-definition camera 303 is located at the rear end of the laser welder 302. The high-definition camera 303 is aligned with the welding position of the tool holder 4 and the tool blank 2.

[0033] It is worth mentioning that the camera channel of the high-definition camera 303 is connected to the laser emission channel of the laser welder 302.

[0034] The welding position between the tool holder 4 and the tool blank 5 is calibrated by a high-definition camera 303. The moving stage 2021 in the lower clamping mechanism 202 keeps the tool holder 4 and the tool blank 5 coaxial, which effectively improves the welding accuracy of the tool holder. The planing tool is welded simultaneously by three laser welding mechanisms 3, which further improves the welding efficiency of the tool holder and improves economic benefits.

[0035] The laser welding mechanism 3 is provided in three parts, which are arranged at 120° intervals. By setting the three laser welding mechanisms 3 at equal intervals to perform laser welding at the same time, not only is the welding efficiency of the tool bar effectively improved, but also the welding position of the tool bar 4 and the tool blank 5 is prevented from jumping due to the impact of the laser beam during welding, thereby further improving the welding accuracy of the planing tool.

[0036] It is worth noting that the three high-definition cameras on the laser welding mechanism simultaneously calibrate three points on the welding position of the tool holder and the tool head blank, which can effectively improve the welding accuracy of the welding equipment and further improve the welding efficiency.

[0037] Furthermore, a first drive motor 304 is provided on one side of the laser welder 302. The first drive motor 304 drives the laser welder 302 to move on the first fixed column 301. When welding with different types and specifications of tool holders, the first drive motor 304 drives the laser welder 302 and the high-definition camera 303 to adjust the welding position and then perform welding, which can adapt to different specifications of planing tools for welding.

[0038] It is worth mentioning that the first drive motor 304 of the three laser welding mechanisms 3 simultaneously drives the laser welder 302 and the high-definition camera 303 to adjust their positions.

[0039] Specifically, the upper clamping mechanism 201 includes a fixed baffle 2011 and a second fixed post 2012. The fixed baffle 2011 is disposed at the upper end of the second fixed post 2012 and is movably connected to the second fixed post 2012. A fixed groove 2013 is provided on the fixed post 2012. During welding, the tool bar is placed in the fixed groove 2013, and the fixed baffle 2011 fixes the tool bar 4.

[0040] Furthermore, the second fixed column 2012 is also provided with a drive cylinder 2014, which drives the fixed baffle 2011 to fix the tool bar 4.

[0041] Specifically, the lower clamping mechanism 202 includes a movable stage 2021, a rotary stage 2022 at the top of the movable stage 2021, a clamping stage 2023 at the top of the rotary stage 2022, and a clamping hole 2024 at the top of the clamping stage 2023. The clamping hole 2024 corresponds to the fixing groove 2013. When the high-definition camera 303 captures a gap between the tool bar 4 and the tool blank 2 at the welding position, the movable stage 2021 can drive the tool blank 5 to move along the X and Y axes to adjust the position between the tool bar 4 and the tool blank 5 so that they are in a coaxial position. The clamping stage 2023 is used to clamp the tool blank 5, and the rotary stage 2022 is used to control the planing tool to perform ring laser welding.

[0042] Furthermore, the clamping table 2023 is provided with a second drive motor 2025, which drives the clamping table 2023 to clamp the cutter head blank 5.

[0043] Specifically, the top of the first fixed column 301 is also provided with a laser conveying line 305 and a laser conveying channel 306. The laser conveying line 305 is located at the top of the laser conveying channel 306, and the laser conveying line 305 and the laser conveying channel 306 are connected to the laser welder 302.

[0044] Working principle: During welding, the tool holder 4 is placed in the fixed groove 2013. The drive cylinder 2014 drives the fixed baffle 2011 to stabilize the tool holder 4 in the fixed groove 2013. Then, the tool blank 5 is placed in the clamping hole 2024. The high-definition camera 303 captures the welding position of the tool holder 4 and the tool blank 5 for calibration. The moving stage 2021 in the lower clamping mechanism 202 moves the tool blank 5 along the X and Y axes to adjust its position, so that the tool holder 4 and the tool blank 5 are in close contact. Three laser welders 302 emit lasers simultaneously to weld. After three welding points are formed, the rotating stage 2022 rotates the tool holder 4 and the tool blank 5 to perform ring welding. When it is necessary to replace the tool holder 4 with different specifications and models, since the welding position of the tool holder 4 and the tool blank 5 is different, the first drive motor 304 drives the laser welder 302 and the high-definition camera 303 to move to the accurate position to repeat the above welding process. This utility model uses the high-definition camera 303 to calibrate the welding position between the tool holder 4 and the tool blank 5, and the moving stage 2021 in the lower clamping mechanism 202 to keep the tool holder 4 and the tool blank 5 coaxial, effectively improving the coaxiality of the tool blank 5 and the tool holder 4, improving the welding accuracy of the planing tool, and using three laser welders 3 to weld the planing tool at the same time, further improving the welding efficiency of the planing tool and reducing labor costs.
