[0002] The robotic milling system is a processing system that uses a robot to perform milling operations. In the robotic milling system, a tool setting instrument is required to meet the tool picking and setting needs of the robotic milling system.

[0003] Tool setters are standard products in the machine tool industry and are divided into contact tool setters, laser tool setters, and magnetic induction tool setters. Laser tool setters are relatively expensive and not cost-effective. Contact tool setters used in common machine tools are actually equivalent to switch signals and can be used with CNC systems, but cannot be used directly with robot systems. Magnetic induction tool setters have a short lifespan, low precision, and weak signal anti-interference capabilities, so they cannot meet the tool picking and setting needs of robot milling systems.

DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] The present embodiment provides a tool picking and setting device for a robot milling system, which is used in conjunction with the robot milling system to provide a tool holder 11 for replacement, thereby realizing automatic tool changing, improving processing efficiency, and protecting personnel safety. The device is simple and easy to operate, greatly shortening the tool changing and setting time of the robot and improving efficiency.

[0028] Combination Figures 1 to 3 As shown, the tool picking and setting device of this embodiment includes a tool picking part 10 and a tool setting part 20. The tool picking part 10 can store a variety of different types of tools to facilitate the robot to perform tool picking operations, and the tool setting part 20 can set the tools to avoid affecting the processing accuracy due to tool wear or tool changing, thereby further ensuring the processing accuracy of the tools.

[0029] Specifically, in this embodiment, the tool taking part 10 includes a plurality of tool holders 11. The tool holders 11 are provided with a receiving cavity. The tool to be taken is arranged in the receiving cavity. When the robot needs to take the tool, it grabs the handle of the tool to take out the tool from the receiving cavity.

[0030] In this embodiment, the tool setting part 20 includes a displacement sensor 21 and a pressure block 22. One end of the displacement sensor 21 is a fixed end, and the other end is a power end. The power end of the displacement sensor 21 corresponds to the position of the pressure block 22. In the initial state, the pressure block 22 contacts the power end of the displacement sensor 21. When the pressure block 22 presses down on the power end of the displacement sensor 21, a pressing distance is formed. In this embodiment, a contact displacement sensor 21 is used. The contact displacement sensor 21 transmits the data of the pressing distance to the robot, providing data so that the robot can calculate the length and height information of the grasped tool.

[0031] See also Figure 1The tool picking and tool setting device of this embodiment also includes a mounting part 30, which includes a mounting frame 31 and a foot cup 32 located at the bottom of the mounting frame 31. The foot cup 32 adjusts the height and level of the mounting frame 31, and the tool picking part 10 and the tool setting part 20 are connected to the mounting frame 31 through a fixing block 40. Therefore, in actual use, the operator can change the height of the tool picking part 10 and the tool setting part 20 by adjusting the foot cup 32, so that the robot can perform subsequent tool picking and tool setting operations.

[0032] In this embodiment, the tool holder 11 is installed on the fixed block 40 through the pad 50, the fixed end of the displacement sensor 21 corresponds to the position of the fixed block 40, and a proximity sensor 90 is provided on the tool holder 11. The proximity sensor 90 can determine whether the tool is on the tool holder 11 so that the subsequent robot can perform logical judgment.

[0033] See also Figure 2 and Figure 3 A fixing frame 60 is provided on the fixing block 40, and a resetting portion 70 for resetting the pressure block 22 is provided on the fixing frame 60. The resetting portion 70 can automatically reset the pressure block 22. After the tool setting is completed, the resetting portion 70 automatically resets the pressure block 22 to facilitate the subsequent tool setting operation.

[0034] Specifically, in this embodiment, the reset portion 70 includes a guide shaft 71 arranged on the fixed frame 60 and a reset spring 72 sleeved on the guide shaft 71. The pressure block 22 is connected to the reset spring 72, and the reset spring 72 automatically resets the pressure block 22. When the tool setting operation is performed, the pressure block 22 squeezes the power end of the displacement sensor 21, driving the reset spring 72 to press down. When the tool setting is completed, the robot moves the tool. At this time, the tool is separated from the pressure block 22, and the pressure block 22 is automatically reset under the action of the reset spring 72, so that the next tool setting operation can be carried out smoothly.

[0035] Furthermore, in this embodiment, a limit block 80 is provided at one end of the guide shaft 71 close to the fixed block 40, and a limit screw 81 is provided on the limit block 80 for limiting the guide shaft 71, and the limit screw 81 can adjust the pre-tightening force of the return spring 72 to meet the tool alignment requirements.

[0036] In actual use of the tool picking and setting device of this embodiment, in the initial state, different types of tools are placed on the tool holder 11, and the tools are grabbed by an external robot. After the tool picking operation is completed, the next step of tool setting operation is carried out. At this time, the robot moves the tool to the top of the pressing block 22, and then presses the pressing block 22 downward, and the power end of the displacement sensor 21 moves downward. After the downward pressing distance is formed, the data is transmitted to the robot, providing data so that the robot can calculate the length and height information of the grabbed tool.

[0037] In summary, the tool picking and setting device of the present embodiment is used in conjunction with the robot milling system to provide it with a replacement tool holder 11, realize automatic tool changing, improve processing efficiency, and protect personnel safety. It is simple and easy to operate, greatly shortens the tool changing and setting time of the robot, and improves efficiency. The tool setting part 20 can set the tool to avoid affecting the processing accuracy due to tool wear or tool changing, further ensuring the processing accuracy of the tool. Compared with traditional tool setting instruments, the use of contact displacement sensor 21 has significantly improved stability and greatly reduced costs.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
