Description

Technical Field

[0001] This utility model relates to the field of welding torch protection technology, and in particular to a protective mechanism for a robotic welding torch. Background Technology

[0002] Welding robots are industrial robots that perform welding (including cutting and spraying). According to the International Organization for Standardization (ISO) definition of industrial robots as standard welding robots, an industrial robot is a multi-purpose, reprogrammable, automated manipulator with three or more programmable axes used in industrial automation.

[0003] Because the equipment and products processed in the production workshop are numerous and varied, workers are prone to accidentally touching the robot's welding torch during their work. Since the welding torch is rigidly connected to its fixed parts, the impact force of the collision acts directly on the welding torch, which can lead to damage to the welding torch. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a protective mechanism for a robotic welding torch, thereby resolving the problems mentioned in the background section.

[0005] A protective mechanism for a robotic welding torch includes a fixed frame mounted on the bottom of the welding torch, an extension slidably disposed inside the fixed frame, a motor mounted on one side of the fixed frame, a gear mounted at the output end of the motor, a toothed plate meshing with the gear mounted inside the extension, and a protective frame slidably disposed at the end of the extension, which can be limited to the extension by a limiting pin.

[0006] By adopting the above technical solution, the welding torch can be protected to avoid damage caused by external impact.

[0007] Fixing blocks are installed on both sides of one end of the fixing frame, and slots are opened on both sides of the extension, so that the fixing blocks can be embedded in the slots and slide in a close fit.

[0008] By adopting the above technical solution, adjustments can be made easily, and the short end of the welding torch can be protected.

[0009] The extension has grooves on both sides of its end, and the protective frame slides along the grooves.

[0010] By adopting the above technical solution, it is possible to adjust the position of the extension.

[0011] The groove is also provided with a circular hole into which a limiting pin can be inserted to confine the protective frame to the extension.

[0012] The above technical solution facilitates the installation of the limiting frame.

[0013] The internal dimensions of the fixing frame are adapted to the dimensions of the extension, and the fixing frame is a hollow structure.

[0014] By adopting the above technical solution, the extension frame is stabilized at the fixed frame.

[0015] The beneficial effects of the protective mechanism of this utility model's robotic welding torch are:

[0016] The drive motor rotates through gears to move the toothed plate, which in turn moves the extension part out of the fixed frame. After the extension part has moved, the protective frame can be manually slid into the end of the extension part and a limit pin can be inserted to fix the protective frame on the extension part, so as to protect the welding torch and prevent the welding torch from being damaged by external impact.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0021] Reference Figure 1-2 A protective mechanism for a robotic welding torch includes a fixed frame 2 installed at the bottom of the welding torch 1, an extension 3 slidably disposed inside the fixed frame 2, a motor 4 installed on one side of the fixed frame 2, a gear 5 installed at the output end of the motor 4, a toothed plate 6 that meshes with the gear 5 installed inside the extension 3, and a protective frame 8 slidably disposed at the end of the extension 3, which can be limited on the extension 3 by a limiting pin 9.

[0022] The drive motor 4 rotates through the gear 5 to push the toothed plate 6 to move. The toothed plate 6 then moves the extension 3 out of the fixed frame 2. After the extension 3 has moved, the protective frame 8 can be manually slid into the end of the extension 3 and the limiting pin 9 can be inserted to limit the protective frame 8 on the extension 3, thus protecting the head of the welding torch 1.

[0023] Fixing blocks 7 are installed on both sides of one end of the fixing frame 2. The extension 3 has slots 301 on both sides, and the fixing blocks 7 can be embedded in the slots 301 and slide in close contact. The fixing frame 2 is installed at the bottom of the welding torch 1. The width of the fixing blocks 7 on both sides inside the fixing frame 2 is adapted to the width of the slots 301 to ensure that the extension 3 can move stably in the fixing frame 2. The front end of the extension 3 has a receiving opening, which can be moved to the end of the welding torch 1 to protect the welding torch 1 in conjunction with the protective frame 8.

[0024] The extension 3 has a sliding groove 302 on both sides of its end, and the protective frame 8 slides along the sliding groove 302. The protective frame 8 can be placed in conjunction with the extension 3 to protect the end of the welding torch 1. The sliding groove 302 also has a round hole for inserting the limiting pin 9 to limit the protective frame 8 on the extension 3, which makes it easy to remove and install the protective frame 8 on the extension 3, and facilitates the operation of the staff.

[0025] The internal dimensions of the fixed frame 2 are adapted to the dimensions of the extension 3, and the fixed frame 2 is a hollow structure. To ensure that the extension 3 can move stably inside the fixed frame 2, and that the outer wall of the extension 3 fits against the inner wall of the fixed frame 2 to achieve stable sliding, the length of the extension 3 is greater than the length of the fixed frame 2. The extension 3 can penetrate the fixed frame 2. When the welding gun 1 needs to be used, the protective frame 8 is removed from the extension 3, and the extension 3 is moved away from the end of the welding gun 1 by the drive of the motor 4, so that the welding gun 1 can be used normally afterwards.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
