[0002] A welding robot is an industrial robot engaged in welding. According to the definition of the International Organization for Standardization, industrial robots belong to standard welding robots. An industrial robot is a multi-purpose, reprogrammable automatic control manipulator with three or more programmable axes used in the field of industrial automation. In order to adapt to different uses, the mechanical interface of the robot's last axis is usually a connecting flange that can be connected to different tools or end effectors. A welding robot is an industrial robot with a welding tongs or welding gun connected to the end axis flange, enabling it to perform welding, cutting or thermal spraying.

[0003] As the working time increases, the robotic arm of the welding robot is prone to heat accumulation, which will affect the subsequent normal operation of the robot. At this time, it needs to be water-cooled. The existing water-cooling device for automatic robot welding is relatively fixed, while the shape and length of the robotic arm are not fixed. This makes it impossible to accurately install and fix the water cooling device on the robotic arm, which greatly reduces the water cooling effect.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 The water-cooling device for automatic welding of the robot comprises a water-cooling filling block 1 and a conductive shell 2. The conductive shell 2 can quickly transfer the temperature to the welding robot. The water-cooling filling block 1 is provided with a water inlet, and a sealed piston is provided on the water inlet. The sealed piston and the water inlet are arranged in cooperation, so that it is convenient for the staff to replace the new water-cooling liquid through the water inlet. The conductive shell 2 is provided with a working groove, and the working groove and the water-cooling filling block 1 are arranged in cooperation. A working slide groove 3 is provided on the outer wall of the conductive shell 2, and a working slider 4 is slidably connected in the working slide groove 3. A connecting pad 5 is fixedly connected to the working slider 4, so that the connecting pad 5 can move under the cooperation of the working slide groove 3 and the working slider 4. Two clamping assemblies are fixedly connected to the connecting pad 5, and the two clamping assemblies are symmetrically arranged to ensure the stability of the clamping;

[0022] The clamping assembly includes an auxiliary plate 6 fixedly connected to the connecting pad 5, and one end of the auxiliary plate 6 away from the connecting pad 5 is threadedly connected with a working bolt 7, and the working bolt 7 is arranged through the auxiliary plate 6. A working clamping plate 8 is fixedly connected to the working bolt 7, so that rotating the working bolt 7 will drive the working clamping plate 8 to move. The two working clamping plates 8 are both made of rubber. The two working clamping plates 8 are arranged in cooperation with each other to avoid damage to the welding robot. A pushing assembly is also provided in the working groove, and the pushing assembly includes two guide slide grooves 9 arranged on the inner wall of the conductive shell 2. The two guide slide grooves 9 are arranged in cooperation with the working groove. Guide sliders 10 are slidably connected in the two guide slide grooves 9, and a pushing plate 11 is fixedly connected to the two guide sliders 10, thereby ensuring that the pushing plate 11 can slide normally;

[0023] A threaded sleeve 12 is also rotatably connected in the working groove, and a pushing screw 13 is threadedly connected in the threaded sleeve 12. The end of the pushing screw 13 away from the threaded sleeve 12 is fixedly connected to the pushing plate 11, so that the pushing screw 13 can drive the pushing plate 11 to move together. A transmission component is also provided in the working groove, and the transmission component includes a working shaft 14 rotatably connected in the working groove. One end of the working shaft 14 penetrates the conductive shell 2, and a handle is provided on the working shaft 14. The handle is disc-shaped, and the handle and the working shaft 14 are matched to make it more convenient for the staff to rotate the working shaft 14. A bevel gear 15 is fixedly connected to the threaded sleeve 12, and a bevel gear 2 16 is fixedly connected to the working shaft 14. The bevel gear 15 and the bevel gear 2 16 are meshed, so that when the working shaft 14 is rotated, the threaded sleeve 12 can be driven to rotate through the gear transmission. A limiting plate 17 is also fixedly connected in the working groove, and the push screw 13 slides through the limiting plate 17. A limiting block is provided on the limiting plate 17, and a limiting groove is provided on the push screw 13. The limiting block and the limiting groove are matched to limit the push screw 13 so that it can only slide along the direction of the threaded sleeve 12.

[0024] During the use of the utility model, the staff first fills the water-cooling filling block 1 with water-cooling liquid, then puts the water-cooling filling block 1 into the conductive shell 2, and then puts the conductive shell 2 on the mechanical arm of the welding robot, and pulls the connecting pad 5 according to the shape characteristics of the mechanical arm. At this time, the connecting pad 5 will start to move under the joint action of the working slide 3 and the working slide block 4, and then drive the auxiliary plate 6 to move together, thereby changing the position of the working clamping plate 8. When it moves to a suitable fixed position, the staff only needs to turn the working bolt 7. Due to the characteristics of the threaded connection, the working clamping plate 8 will start to move and clamp the mechanical arm.

[0025] When the cooling effect of the water-cooled filling block 1 is not obvious, the staff only needs to rotate the working shaft 14 to make the bevel gear 2 16 fixedly connected to it rotate. Due to the characteristics of gear meshing, the bevel gear 1 15 will also start to rotate, thereby driving the threaded sleeve 12 to rotate. Due to the characteristics of the threaded connection, the pushing screw 13 will slide along the direction of the threaded sleeve 12 under the limiting action of the limiting plate 17, thereby driving the pushing plate 11 to move together, thereby driving the water-cooled filling block 1 to move under the joint action of the guide groove 9 and the guide slider 10. At this time, the water-cooled filling block 1 can be pushed to the outside of the conductive shell 2. The staff only needs to replace the internal water-cooling liquid and then move the water-cooled filling block 1 to the inside of the conductive shell 2.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
