[0027] The present utility model provides an automatic inner wall grinding device for a pipe pile mold. Please refer to Figure 1 and Figure 2 , including a grinding tooling 1 for placing the pipe pile mold 100 to be ground; at least one set of grinding components is provided at the end of the grinding tooling 1 for grinding the inner wall of the pipe pile mold 100; the grinding components reciprocate along the grinding ground rail 2, so as to grind the inner wall of the pipe pile mold 100 multiple times.

[0028] The automatic inner wall grinding device for the pipe pile mold further includes a dust-proof component for handling the metal waste generated during the grinding of the pipe pile mold 100.

[0029] Specifically, there are two groups of the grinding components, which are distributed at both ends of the grinding tooling 1, and the two groups of grinding components perform grinding processing simultaneously from both ends of the pipe pile mold 100 towards the middle.

[0030] In one embodiment, the two groups of grinding components are the same and can perform grinding processing simultaneously from both ends towards the middle, thereby improving the processing efficiency of the inner wall grinding of the pipe pile mold 100. In one embodiment, the two groups of grinding components are different, and the same grinding equipment can be used to grind the inner wall of the pipe pile mold 100 with different structures or specifications.

[0031] In this embodiment, the grinding ground rail 2 is located on one side of the grinding tooling 1 and extends along the length direction of the grinding tooling 1. The two groups of grinding components reciprocate on the same grinding ground rail 2.

[0032] Furthermore, the length of the grinding ground rail 2 is greater than the length of the grinding tooling 1, that is, the length of the grinding ground rail 2 is greater than the length of the pipe pile mold 100. Whether the grinding component grinds from one end of the pipe pile mold 100 to the other end, or the two groups of grinding components grind from both ends of the pipe pile mold 100 towards the middle, the entire inner wall of the pipe pile mold 100 can be guaranteed to be ground.

[0033] Specifically, the grinding component includes a robotic arm 3 and a tool magazine 4. The robotic arm 3 and the tool magazine 4 are installed on the same sliding seat and move synchronously along the grinding ground rail 2. When the length of the pipe pile mold 100 is relatively long, the robotic arm 3 and the tool magazine 4 move synchronously, and the robotic arm 3 can call the tools in the tool magazine 4 at any time without returning, further improving the processing efficiency.

[0034] In one embodiment, a variety of tools are distributed in the tool magazine 4, and the robotic arm 3 grabs the corresponding tools according to the process to grind the inner wall of the pipe pile mold 100.

[0035] In the embodiment of the present utility model, the tools in the tool magazine 4 include, but are not limited to, taper milling cutters, spherical milling cutters, taper buffing wheels, and ball head buffing wheels. Different tools correspond to different processing procedures; and a line laser probe is also provided in the tool magazine 4 for detecting the processed surface. If the processing requirements are not met, supplementary processing can be realized by using CAM software until the requirements are met.

[0036] Specifically, each group of the grinding components is equipped with a cooling water tank 5. The cooling water tank 5 transports cooling water to the end of the robotic arm 3 through a water pipe to provide cooling for the grinding processing process.

[0037] Specifically, the dustproof component includes a dustproof cover 6, a dustproof air duct and a dustproof main unit 7. The dustproof cover 6 moves synchronously with the grinding component to collect metal waste generated during the grinding process in real time. The dustproof cover 6 is connected to the dustproof main unit 7 through the dustproof air duct. Under the negative pressure of the dustproof main unit 8, the metal waste is sucked into the dustproof main unit 7 through the dustproof air duct.

[0038] Furthermore, the dustproof air duct includes a dustproof main air duct 8 and a dustproof branch air duct 9, wherein the dustproof main air duct 8 extends along the length direction of the grinding rail 2 and is connected to the dustproof main unit 7; and one end of the dustproof branch air duct 9 is connected to the dustproof cover 6, and the other end is slidably connected to the dustproof main air duct 8. When the dustproof cover 6 moves synchronously with the grinding assembly, the dustproof branch air duct 9 slides along the dustproof main air duct 8, and the dustproof branch air duct 9 is always connected to the dustproof main air duct 8.

[0039] In some embodiments, the grinding tool 1 is a V-shaped tool, which uses gravity to clamp the pipe pile mold 100 to be ground, and uses a line laser probe to align, accurately obtain the 3D digital model of the grinding area, and generate a smooth tool path trajectory through customized CAM software to ensure a smooth transition between the grinding area and both sides.

[0040] The process of grinding a rectangular cross-section pipe pile mold using the automatic grinding device for the inner wall of the pipe pile mold is as follows: first, the pipe pile mold 100 to be ground is hoisted into the grinding fixture 1, and the robot arm 3 replaces the line laser probe (or binocular camera + structured light), and uses the line laser probe in conjunction with the grinding component to obtain the point cloud map of the welding part. Then, the 3D reconstruction of the welding part is realized by reverse engineering, and the tool path trajectory is generated by the CAM software to ensure the smooth transition of the weld area. Then the left large plane is milled: the tapered milling cutter realizes row cutting along the X-axis direction, and after milling a row, it performs stepping motion along the Y-axis direction, and repeats the above cycle to complete the milling of the left large surface; at the same time, each time the milling cutter feeds along the X-axis, the robot arm 3 adjusts the corresponding angle according to the inclination angle of the large surface of the workpiece. Then repeat the above steps to mill the right large plane. Then the robot arm 3 replaces the spherical milling cutter to mill the upper left corner arc; the spherical milling cutter is used to cut along the X-axis direction, and the arc is smoothed in one processing; then the above steps are repeated to mill the upper right corner arc. Then, the robot arm 3 replaces the tapered shutter wheel and completes the large surface grinding in the milling sequence (staggered with the milling cutter marks, and the milling cutter marks are polished clean); then the ball-head shutter wheel is replaced to complete the grinding of the three arc surfaces in the milling sequence. Finally, the robot arm 3 replaces the line laser probe to detect the processed surface again. If it does not meet the processing requirements, the CAM software can be used to perform additional processing until it meets the requirements.

[0041] The process of grinding the circular cross-section pipe pile mold using the automatic grinding equipment for the inner wall of the pipe pile mold is as follows: first, the pipe pile mold 100 to be ground is hoisted into the grinding tooling 1, and the robot arm 3 replaces the line laser probe (or binocular camera + structured light), and uses the line laser probe in conjunction with the grinding component to obtain the point cloud map of the welding part. Then, reverse engineering is used to achieve 3D reconstruction of the welding part, and the tool path trajectory is generated by the CAM software to ensure the smooth transition of the weld area. Then the robot arm 3 is used to mill the entire arc surface from the starting section on the left side of the arc to the ending end on the right side of the arc. Then the robot arm 3 replaces the tapered louver wheel to grind the arc surface in the milling order and stagger the tool marks. Finally, the robot arm 3 replaces the line laser probe to detect the processed surface again. If it does not meet the processing requirements, the CAM software can be used to perform supplementary processing until it meets the requirements.

[0042] The above description is only a description of the preferred embodiment of the utility model, and is not any limitation on the scope of the utility model. Any changes and modifications made by ordinary technicians in the field of the utility model based on the above disclosure shall fall within the scope of protection of the claims.
