The body size, moving space, and the space occupied by the robot control cabinet of this type of robot are relatively large, and the robot itself weighs more than 150 kg. It can only be installed by attaching to a fixed base or a bottom moving track. As shown in Figure 1 and Figure 2 , the use range and location of the robot are greatly compressed by this type of robot. Moreover, inside some medium and large-sized workpieces, this robot cannot enter due to its body size limitation. Although the existing robot can increase its moving range by adding external axes (floor track, cantilever mechanism), it also greatly increases its cost and is difficult to meet customer requirements. Summary of the Utility Model

[0003] Based on this, in view of the problem that existing welding robots are difficult to reach the inside or edge welds of medium, large, and heavy welding workpieces, it is necessary to provide a mobile and liftable robot.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0025] Please refer to Figure 3 and Figure 4(The cooling water tank and the gas storage tank are not shown in the figure). This embodiment provides a mobile and liftable robot, which includes a trolley body 1. The trolley body 1 can adopt a wheelbarrow structure, that is, the movement of the trolley body 1 has no other power drive. A handle is provided on one side of the trolley body 1, and it can be pushed only by relying on human power to hold the handle. In this embodiment, the area specification of the trolley body 1 can be made into 1200*640mm, and welding power sources 2, cooling water tanks, wire feeders 3, gas storage tanks, control cabinets 4 and other equipment supporting the welding robot with corresponding specifications can be installed on the trolley body 1 according to user requirements. One special point is that a liftable column 5 is also connected to the trolley body 1. A robot body 6 is installed on the top of the column 5. Specifically, the column 5 can use a 24v / 90w DC motor as the power, use a T-shaped lead screw as the lifting structure, and use an aluminum alloy square tube as the outer shell of the column 5, so that the outer shell has the advantages of light weight and high strength. Further, the column 5 can be lifted by a remote control method, making the height adjustment of the welding robot more convenient during use. The robot body 6 adopts a commercially available standard model robot, and it is connected to the column 5 through a specially set fixing mechanism. In this embodiment, as Figure 5 and Figure 6 shown, the fixing mechanism includes a mounting plate and a mounting seat 7. Among them, the mounting plate includes a disc part 8 and a rectangular frame 9. A plurality of first mounting holes are evenly distributed in a ring along the center of the disc part 8, usually 4 can be set. The rectangular frame 9 is fixedly connected to the bottom of the disc part 8, and at the same time, the rectangular frame 9 is sleeved on the top of the outer shell of the column 5. In order to make the connection more stable, a number of threaded holes are respectively opened in four directions of the rectangular frame 9. Set screws are arranged in the threaded holes. The rectangular frame 9 and the column 5 are locked by the set screws. The mounting seat 7 is set as a frustum of a cone with a thin-walled structure, and both the upper bottom surface and the lower bottom surface of the mounting seat 7 are open. A plurality of clearance grooves 71 are evenly distributed in a ring along its axis on the side surface of the mounting seat 7. A second mounting hole is opened in the lower end of the inner wall of each clearance groove 71 along the vertical direction. The position distribution of the plurality of second mounting holes needs to correspond to the first mounting holes. The top of the mounting seat 7 can be connected to the robot body 6 by bolts or welding. When fixing the robot body 6 and the column 5, first align the second mounting holes on the mounting seat 7 with the first mounting holes on the disc part 8, and then install bolts between the aligned second mounting holes and the first mounting holes. It is worth mentioning that the position of the column 5 is preferably set at the corner of the trolley body 1. This design can make the robot body 6 extend further on the trolley body 1, reduce the blocking distance between the trolley body 1 and the welding workpiece, and make the robot body 6 easier to reach the inner or edge welds of the welding workpiece. Especially for the welding of large boxes, such as Figure 7As shown, due to the high height of the large box body, a conventional fixed-base welding robot needs to be equipped with an external axis mechanism, while this mobile and liftable robot can directly lift to weld the internal or edge welds of the workpiece. A corresponding support frame can also be installed on the main body 1 of the trolley to fix equipment such as gas storage tanks and wire feeders 3 that are difficult to fix or movable.

[0026] In summary, the present utility model provides a lightweight, small and portable collaborative robot that can move the welding trolley by hand, making the welding system move flexibly. The arm span of this mobile and liftable robot can be extended by 300 - 1000 mm in the Z-direction stroke. Compared with the conventional fixed-base welding robot, it can greatly increase the welding range, thus eliminating the need to manufacture auxiliary mechanisms such as large external axes. At the same time, this mobile and liftable robot has a high degree of integration, is portable and flexible. The main body 1 of the trolley only requires a square tube welding trolley frame with an area of 1200*640 mm and a standard model robot, and is equipped with a welding power source 2 and a wire feeder 3 and other equipment according to the corresponding requirements of the user. When a conventional fixed-base welding robot includes the same equipment as this mobile and liftable robot, the floor area is about 4 square meters, and it can only be fixed in place and cannot move. Therefore, this mobile and liftable robot can greatly save the procurement cost for customers and at the same time fill the part that medium and large welding robots are limited and cannot meet the welding needs of customers. The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0027] The above-described embodiments only represent several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
