When the mechanical arm produces great vibration during the welding process, the first supporting frame and the second supporting frame can provide certain stability for the mounting frame, prevent the mounting frame from moving and improve the welding quality.

Description

Technical Field

[0001] This application relates to the field of automated welding technology, and more specifically, to a mobile structure for a welding robot. Background Technology

[0002] Traditional welding processes are typically performed manually. This manual method presents several limitations and challenges, such as inconsistent weld quality, operational safety, welding efficiency, and high labor costs. To overcome these issues, welding robots have emerged to replace manual welding.

[0003] However, welding robots consist of collaborative robots (robotic arms), robot control boxes, welding machines and wire feeding systems, welding gas cylinders and gas pipe systems, and power control boxes. Because welding sites are scattered and mobile equipment is relatively heavy, workers will fix the welding robot on a mounting frame. The bottom of the mounting frame is equipped with rotating wheels, and the welding robot can be moved by pushing the mounting frame with external force. However, after the welding robot moves to a fixed position, the vibration generated by the robotic arm during welding can easily cause the mounting frame to move, affecting the welding quality.

[0030] Reference Figure 1-5 ,

[0031] A mobile structure for a welding robot includes: a mounting frame 1, a first support frame 2, a second support frame 8, rotating wheels 3, and omnidirectional wheels 7; specifically, the rotating wheels 3 are beach tires. The mounting frame 1 has a mounting platform 11 for placing the welding robot; the first support frame 2 and the second support frame 8 are disposed on the side of the mounting frame 1 facing away from the mounting platform 11, and are located at opposite ends of the mounting frame 1, with the first support frame 2 rotatably connected to the mounting frame 1; two rotating wheels 3 and two omnidirectional wheels 7 are respectively mounted on the mounting frame 1, and both are in contact with the ground; the two omnidirectional wheels 7 are positioned close to the first support frame 2; specifically, a transmission rod is provided between the two rotating wheels 3, and two bearing seats are provided at the bottom of the mounting frame 1, the inner diameter of the bearings in the bearing seats matching the outer diameter of the transmission rod, the transmission rod being rotatably connected to the bearing seats, and the number of bearing seats being the same as the number of rotating wheels 3. The diameter of the rotating wheels 3 is larger than the diameter of the omnidirectional wheels 7, and when the first support frame 2 and the second support frame 8 are in contact with the ground, the rotating wheels 3 are tangential to the ground or form a gap with the ground. By rotating the first support frame 2, the ends of the first support frame 2 and the second support frame 8 that are away from the mounting frame 1 come into contact with the ground, thus fixing the mounting frame 1 in a fixed position on the ground. When the robotic arm 15 generates large vibrations during the welding process, the first support frame 2 and the second support frame 8 can provide a certain degree of stability for the mounting frame 1, prevent the mounting frame 1 from moving, and improve the welding quality.

[0032] Specifically, the mounting bracket 1 has a receiving groove 16 at its bottom; a magnetic block 161 is provided inside the receiving groove 16; the magnetic block 161 is a magnet, and the first support frame 2 is made of iron. When the first support frame 2 is rotated relative to the mounting bracket 1 by external force, and the end of the first support frame 2 away from the mounting bracket 1 is located in the receiving groove 16, the first support frame 2 is attracted to the magnetic block 161. The magnetic block 161 is used to attract and fix the first support frame 2 to prevent the first support frame 2 from scraping against the ground when the user moves the mounting bracket 1. When the end of the first support frame 2 away from the mounting bracket 1 is located in the receiving groove 16, the sound produced when the magnetic block 161 attracts the first support frame 2 can remind the user that the first support frame 2 is firmly fixed.

[0033] Specifically, the welding robot's moving structure also includes: a locking rod 9; the locking rod 9 has a first locking part 91 and a second locking part 92; both the first locking part 91 and the second locking part 92 are block structures. When the first support frame 2 and the second support frame 8 are perpendicular to the ground, the distance between the first support frame 2 and the second support frame 8 is equal to the distance between the first locking part 91 and the second locking part 92. Both the first locking part 91 and the second locking part 92 have slots for engaging with the first support frame 2 and the second support frame 8. When the ends of the first support frame 2 and the second support frame 8 that are away from the mounting frame 1 are in contact with the ground, the user can place the locking rod 9 above the first support frame 2 and the second support frame 8, and engage the ends of the first support frame 2 and the second support frame 8 that are away from the mounting frame 1 into the slots. This locks the second support frame 8 and the first support frame 2 with the locking rod 9, preventing the mounting platform 11 or the first support frame 2 from shaking when the mounting frame 1 is subjected to external force. In this embodiment, two locking rods 9 are provided, and the two locking rods 9 are fixedly connected by a connecting rod, so that the locking rods 9 can more stably connect the first support frame 2 and the second support frame 8.

[0034] Specifically, the welding robot's moving structure also includes: a welding gas tank 12, a mounting frame 17, and limiting rods 4; the mounting frame 17 is mounted on the mounting platform 11; the height of the mounting frame 17 on the mounting frame 1 is greater than half the length of the welding gas tank 12; the mounting frame 17 has a placement area 171 for placing the welding gas tank 12, and an inlet 172 communicating with the placement area 171; specifically, the opening direction of the inlet 172 is perpendicular to the mounting platform 11. Multiple mounting holes are provided on both sides of the inlet 172, the diameter of which is greater than or equal to the diameter of the limiting rods 4, which are used to close the inlet 172. In this embodiment, the number of mounting holes is twice the number of limiting rods 4, and three limiting rods 4 are provided. The mounting frame 17 and the limiting rods 4 can enclose the welding gas tank 12, preventing it from falling off when the mounting frame 1 moves. When replacing the welding gas cylinder 12, the user can pull out the limiting rod 4 and take the welding gas cylinder 12 out from the inlet 172. When putting it in, the welding gas cylinder 12 enters the placement area 171 through the inlet 172. Then, the limiting rod 4 is inserted into the installation hole to block the inlet 172.

[0035] Specifically, the welding robot's moving structure also includes: a welding machine 14; and a first limiting part 111 on the mounting platform 11, which is a plate-like structure. The first limiting part 111 forms a first mounting area for placing the welding machine 14; the first limiting part 111 extends away from the rotating wheel 3. The first limiting part 111 is used to enable the welding machine 14 to be quickly placed on the mounting platform 11, and to ensure that the welding machine 14 is in a fixed position on the mounting platform 11 when the mounting frame 1 moves. During equipment maintenance, the user can lift the welding machine 14 to detach it from the mounting platform 11, making the operation simple.

[0036] Specifically, the welding robot's moving structure also includes: a control box 13; the mounting frame 17 is provided with a second limiting part 173, which is a plate-like structure. The second limiting part 173 forms a second mounting area for placing the control box 13; the second limiting part 173 extends away from the rotating wheel 3. The second limiting part 173 is used to enable the control box 13 to be quickly placed on the mounting frame 17, and to ensure that the control box 13 is in a fixed position on the mounting frame 17 when the mounting frame 1 moves. During equipment maintenance, the user can lift the control box 13 to detach it from the mounting frame 17, making the operation simple.

[0037] Specifically, the mounting frame 17 has a mounting section 174, which is a plate structure. The mounting section 174 extends away from the rotating wheel 3. The welding robot's moving structure also includes: a robotic arm 15, a rotating disk 5, and a lead screw 6. The mounting section 174 has a mounting groove that extends perpendicular to the horizontal plane. The lead screw 6 is rotatably mounted in the mounting groove. The robotic arm 15 has a connecting section 151 that is slidably connected to the mounting section 174, and a welding torch located away from the connecting section 151. The robotic arm 15 has multiple degrees of freedom. The connecting section 151 is a block structure. The connecting section 151 has a threaded hole that is threadedly connected to the lead screw 6. The rotating disk 5 is located at the end of the lead screw 6 away from the mounting frame 1. The rotating disk 5 and the lead screw 6 are provided to adjust the height of the robotic arm 15. Through the transmission of the lead screw 6, the position of the connecting section 151 on the mounting section 174 can be controlled very precisely, so that the robotic arm 15 can be adjusted to the optimal working point.

[0038] Specifically, the mounting frame 17 has a gripping part 175 for hand gripping at one end away from the robotic arm 15, so that the user can push the mounting frame 1 to move.
