[0003] Gas shielded welding needs to use protective gas during welding operation, which needs to be stored in a gas cylinder. With the continuous development of welding technology, the welding gas cylinder rack as a key device for supporting and fixing the gas cylinder has gradually attracted attention in the industry. At present, most of the welding gas cylinder racks on the market adopt traditional architecture design, which can meet the basic fixing and supporting requirements, but in the actual use process, especially in the case of frequent replacement of gas cylinders, the operation convenience is not satisfactory.

[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0048] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0049] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] Embodiments of this application provide an installation device 300 and a welding robot 1000, such as Figure 2 As shown, the mounting device 300 can be mounted on the welding robot 1000, such as... Figure 1 and Figure 5 As shown, the mounting device 300 provides a mounting base for the gas cylinder 520, which stores welding shielding gas. This welding shielding gas provides protection for the welding operation of the welding robot 1000. The mounting device 300 can lift and lower the gas cylinder 520. When the gas cylinder 520 needs to be replaced, the mounting device 300 lowers the original gas cylinder 520 to the ground, and the operator removes the original gas cylinder 520 from the mounting device 300 and installs the new gas cylinder 520 onto the mounting device 300. Figure 1 As shown, the lifting device 300 lifts the gas cylinder 520, keeping it away from the ground. During the movement of the welding robot 1000, keeping the gas cylinder 520 away from the ground prevents it and the installation device 300 from touching the ground. When changing the gas cylinder 520, the operator does not need to manually carry it onto the welding robot 1000; they only need to use the installation device 300 to lift it. This saves the operator's physical strength. Furthermore, the installation device 300 assists the operator in changing the gas cylinder 520, avoiding the risks associated with manually carrying it, reducing operational difficulty and safety hazards, and improving the efficiency of gas cylinder 520 replacement.

[0051] Firstly, such as Figure 1 As shown, the installation device 300 provided in this application includes a frame 310, a drive component 320, a lifting component 330, and a limiting component.

[0052] As shown in Figure 2 , the rack 310 is fixedly arranged on the mobile vehicle 100 of the welding robot 1000, for example by welding, clamping or bolting.

[0053] As shown in Figure 7 and Figure 8 , the driving member 320 is arranged on the rack 310, and is used to drive the lifting member 330 to move. For example, the driving member 320 includes but is not limited to a telescopic mechanism or a gear and rack driving mechanism.

[0054] As shown in Figure 6 to Figure 8 , the lifting member 330 is arranged on the rack 310, and is provided with a placing position for placing the gas cylinder 520.

[0055] As shown in Figure 9 , the lifting member 330 is connected with the driving member 320, so that the driving member 320 can drive the lifting member 330 to move reciprocally along a first direction, for example a Z-axis direction. The lifting member 330 is connected with the driving member 320 through a transmission mode, so that the driving member 320 can drive the lifting member 330 to move.

[0056] Under the action of the driving member 320, the lifting member 330 can drive the gas cylinder 520 to move along the first direction.

[0057] A limiting member is arranged on the lifting member 330, and is used to limit the gas cylinder 520 from moving along a second direction perpendicular to the first direction.

[0058] As shown in Figure 2 , for example, the first direction is a Z-axis direction, and the second direction is an X-axis direction or a Y-axis direction. For example, the Z-axis direction is a vertical direction, and the X-axis direction and the Y-axis direction are horizontal directions.

[0059] The mounting device 300 can drive the gas cylinder 520 to move up and down, so that when the gas cylinder 520 is replaced, the operator does not need to manually carry the gas cylinder 520 to the welding robot 1000, which not only saves the physical strength of the operator, but also avoids the risks and safety hazards that may be caused by manually carrying the gas cylinder 520. By replacing the gas cylinder 520 in a mechanical way, the replacement efficiency can be significantly improved, and human operation errors can be reduced.

[0060] In one embodiment, as shown in Figure 7 , the rack 310 is provided with a cover 319 for isolating and protecting the driving member 320.

[0061] By setting the cover 319 on the frame 310, the driving member 320 can be effectively isolated and protected, preventing the gas cylinder 520 or other objects from accidentally bumping into the driving member 320 during operation, thereby avoiding damage to the driving member 320. This helps to prolong the service life of the driving member 320, reduce the frequency of maintenance and replacement, and reduce maintenance costs.

[0062] In another embodiment, the cover 319 is a hollow shell structure. By designing the cover 319 as a hollow shell structure, the weight of the cover 319 can be significantly reduced while ensuring structural strength. This not only helps to reduce the load and improve operating efficiency, but also helps to reduce manufacturing costs and material consumption. At the same time, the hollow design can effectively release internal stress, preventing the cover 319 from deforming during welding or assembly, further improving its deformation resistance.

[0063] As shown in Figure 5 to Figure 8 In one embodiment, the frame 310 includes a first support 312 and a guide 316.

[0064] As shown in Figure 4 The first support 312 is provided on the mobile vehicle 100 of the welding robot 1000. The guide 316 is provided on the first support 312, and the guide 316 has a guide portion for guiding the lifting member 330 to slide in the first direction.

[0065] The lifting member 330 includes a sliding portion 332 and a support portion 334. The sliding portion 332 is provided in the first direction and connected with the driving member 320. The sliding portion 332 is in sliding connection with the guide portion. The support portion 334 is provided on the sliding portion 332. The placing position is provided on the support portion 334. Under the action of the driving member 320, the sliding portion 332 moves along the guide portion and drives the support portion 334 to move. The movement of the support portion 334 drives the movement of the gas cylinder 520.

[0066] In one embodiment, the guide 316 is a guide rail, and the sliding portion 332 has a groove body matched with the guide rail. The sliding portion 332 is slidingly installed on the guide rail. The guide rail is provided in the first direction, i.e. the guide rail is provided in the Z-axis direction. The driving member 320 can drive the sliding portion 332 to reciprocate on the guide rail in the Z-axis direction. However, in another embodiment, as shown in Figure 8 and Figure 9As shown, the guide 316 is a guide cylinder, both ends of the guide cylinder have openings, and the hollow structure of the guide cylinder is a guide part. The guide cylinder is fixedly arranged on the first support 312 in the first direction, and the fixed connection is achieved by welding, clamping, riveting, or bolt connection, etc. The sliding part 332 is a sliding rod, the sliding rod is arranged in the opening, and a part of the sliding rod is located in the hollow structure. The sliding rod abuts against the inner wall of the hollow structure. The inner wall of the hollow structure limits the movement of the sliding rod in the radial direction of the guide cylinder, so that the sliding rod can only reciprocate in the axial direction of the guide cylinder.

[0067] The guide rail or guide cylinder is used as the guide 316. The guide rail design provides a stable linear motion trajectory, and the hollow structure of the guide cylinder limits the radial movement of the sliding rod, ensuring the accuracy and stability of the sliding.

[0068] In one embodiment, the driving part 320 further includes a driving end 321. The driving end 321 of the driving part 320 is connected to the rod body of the sliding rod located outside the guide cylinder, so that the driving part 320 can drive the sliding rod to reciprocate on the guide cylinder in the first direction. However, in another embodiment, as shown in Figure 8 and Figure 9 In the first direction, a strip-shaped hole 318 is formed in the guide cylinder. The driving part 320 includes a driving end 321. The driving end 321 is arranged in the strip-shaped hole 318 and connected to the sliding part 332, so that the driving part 320 can drive the sliding rod to reciprocate on the guide cylinder in the first direction.

[0069] The driving end 321 of the driving part 320 is connected to the rod body of the sliding rod located outside the guide cylinder. During the extension and retraction of the driving part 320, after the sliding rod moves to the limit position in the guide cylinder, the driving end 321 can abut against the end face of the guide cylinder to limit the sliding rod at the limit position in the guide cylinder. The driving part 320 does not need to always maintain the extension length to keep the sliding rod at the limit position in the guide cylinder, thereby saving energy consumption.

[0070] The driving end 321 is arranged in the strip-shaped hole 318 and connected to the sliding part 332. During the extension and retraction of the driving part 320, after the sliding rod moves to the limit position in the guide cylinder, the driving end 321 abuts against the inner wall of one end of the strip-shaped hole 318. The inner wall of the strip-shaped hole 318 limits the displacement of the driving end 321, and further limits the displacement of the sliding rod, so as to limit the sliding rod at the limit position in the guide cylinder. The driving part 320 does not need to always maintain the extension length to keep the sliding rod at the limit position in the guide cylinder, thereby saving energy consumption.

[0071] Exemplarily, the driving end 321 and the sliding rod are connected by a bolt or a pin shaft 150, etc.

[0072] As shown in Figure 8 and Figure 9As shown, in one embodiment, the rack 310 further comprises a second bracket 314, the first bracket 312 is connected to one end of the guide 316, and the second bracket 314 is connected to the other end of the guide 316, and the driving member 320 is arranged on the first bracket 312. But in another embodiment, the driving member 320 is arranged on the second bracket 314.

[0073] By fixing the two ends of the guide 316 by the first bracket 312 and the second bracket 314 respectively, the stability of the guide 316 can be ensured. This double support structure can effectively prevent the guide 316 from shaking or shifting during work.

[0074] The stable guide 316 support structure can reduce the wear and failure rate of the sliding part 332, thereby improving the reliability and durability. This design helps to prolong the service life of the machine and reduce maintenance costs.

[0075] In one embodiment, as shown in Figure 2 and Figure 4 The welding robot 1000 is provided with a triangular bracket 140 on the motor vehicle. As shown in Figure 5 to Figure 7 The triangular bracket 140 is provided with a pin shaft 150, and the first bracket 312 is provided with a matching through hole matched with the pin shaft 150. The first bracket 312 is arranged on the pin shaft 150 through the matching through hole, the pin shaft 150 is arranged in the matching through hole, the first bracket 312 is rotatably installed on the pin shaft 150, and the pin shaft 150 limits the displacement of the first bracket 312 along the radial direction of the pin shaft 150.

[0076] When installing, first, the first bracket 312 is installed on the pin shaft 150, then the first bracket 312 is rotated, the guide 316 is close to the second bracket 314, the guide 316 abuts against the second bracket 314, and then the guide 316 is fixedly connected to the second bracket 314, so that the assembly method is quick and convenient, and the assembly efficiency is improved. If the first bracket 312 and the second bracket 314 are fixedly connected to the guide 316 by bolts, in the assembly process, one end of the guide 316 needs to be fixed to the corresponding height of the rack 310 first, and then the other end is installed on the rack 310, and after the other end is installed, the previously fixed end is installed on the rack 310. In this application, one end of the guide 316 is fixed while the guide 316 is installed on the first bracket 312, which saves the assembly steps and improves the assembly efficiency and difficulty.

[0077] By adopting the design of the pin shaft 150 and the matching through hole, the first support 312 can be rotatably installed on the triangular support 140. This design simplifies the assembly process, because only the first support 312 needs to be installed on the pin shaft 150, then the first support 312 is rotated to make the guide 316 close to and abut against the second support 314, and finally fixed. Compared with the traditional bolt fixing method, this method greatly reduces the assembly steps.

[0078] The traditional bolt fixing method needs to repeatedly adjust the height and position of the two ends during assembly, while the present application only needs to install and fix the guide 316 on the first support 312 once, thereby significantly improving the assembly efficiency.

[0079] Since the pin shaft 150 restricts the displacement of the first support 312 in the radial direction of the pin shaft 150, it is not necessary to pay too much attention to the stability of the first support 312 during assembly, thereby reducing the difficulty of assembly. At the same time, the complexity of bolt fixing and the fine requirement for height adjustment are reduced.

[0080] The first support 312 can rotate relative to the triangular support 140, which increases the flexibility of the mechanical structure, making it more convenient during installation and adjustment.

[0081] Through the connection mode of the pin shaft 150 and the matching through hole, the connection between the first support 312 and the triangular support 140 can be ensured to be stable and reliable, thereby improving the reliability of the entire mechanical structure.

[0082] As shown in Figure 8 and Figure 9 In one embodiment, the second support 314 includes a fixed part 314a and a connecting part 314b. The fixed part 314a is a hollow frame structure, and the fixed part 314a is fixedly connected with the connecting part 314b. The connecting part 314b is provided with a through hole matched with the guide 316, and the other end of the guide 316 is installed at the through hole on the connecting part 314b.

[0083] During installation, the guide 316 is installed on the pin shaft 150 through the first support 312, then the connecting part 314b is fixedly connected on the guide 316, the fixed part 314a is fixed on the moving vehicle 100 of the welding robot 1000, the first support 312 is rotated to make the guide 316 close to the fixed part 314a, the fixed part 314a abuts against the connecting part 314b, and then the fixed part 314a and the connecting part 314b are fixed. This step-by-step installation method makes the whole process more orderly and easy to operate. At the same time, due to the rationality of the structural design, the disassembly process is also simple.

[0084] By dividing the second support 314 into a fixed part 314a and a connecting part 314b, the entire mechanical structure exhibits a modular feature. This design allows each part to be manufactured, installed, and maintained independently, thereby improving production efficiency and simplifying the maintenance and replacement process in the later stage.

[0085] The fixed part 314a adopts a hollow frame structure, which not only realizes lightweight design and reduces material usage, but also ensures the strength and stability of the structure. This design not only conforms to the environmental protection concept of energy saving and emission reduction, but also reduces production costs. In some embodiments, the fixed part 314a is made of sheet metal, and the hollow frame structure of the fixed part 314a can also reduce internal stress and avoid excessive deformation of the fixed part 314a during welding or installation.

[0086] As shown in Figure 8 and Figure 9 , in one embodiment, the limiting part includes a first limiting structure 340, which is arranged on the support part 334 and is used to limit the movement of the bottom of the gas cylinder 520 in the second direction.

[0087] As shown in Figure 8 and Figure 9 , in one embodiment, the first limiting structure 340 is a limiting protrusion 342 arranged on the support part 334; but in another embodiment, the first limiting structure 340 is a limiting groove arranged on the support part 334.

[0088] By setting the limiting protrusion 342 or the limiting groove as the first limiting structure 340, the movement of the bottom of the gas cylinder 520 in the second direction (the second direction is parallel to the horizontal direction or slightly inclined to the horizontal direction, depending on the actual application scenario) can be effectively limited. This design ensures that the gas cylinder 520 can remain stable during transportation or use, preventing potential safety risks caused by accidental movement.

[0089] The design of the limiting protrusion 342 or the limiting groove is relatively simple and easy to process and manufacture. At the same time, this structure also makes the installation process more convenient, allowing the gas cylinder 520 to be quickly and accurately placed on the support part 334 and effectively limited by the first limiting structure 340.

[0090] During transportation or use, accidental movement of the gas cylinder 520 can cause serious safety accidents. By setting the first limiting structure 340, this risk can be greatly reduced, improving overall safety.

[0091] The limiting structure not only limits the movement of the gas cylinder 520, but also plays a role in protecting the gas cylinder 520 to some extent. During transportation or handling, the limiting structure can reduce the collision and friction between the gas cylinder 520 and other objects, thereby prolonging the service life of the gas cylinder 520.
