[0020] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0021] It should be noted that these and other subsequent drawings are only examples and are not drawn in proportion, and should not be used as a limitation on the actual scope of protection required by the present utility model.

[0022] Aiming at the problem that irregular reinforcement rings are difficult to weld automatically, an automatic welding trolley for reinforcement rings is proposed.

[0023] As reference Figures 1 to 4 It is understood that the reinforcement ring automatic welding carriage 3 is used to weld the reinforcement ring 2 located on the partition 1.

[0024] The reinforcement ring automatic welding carriage 3 comprises a walking device 31, a multi-dimensional moving device 32, a carrying handle 33, a welding gun clamping device 34 and a control component.

[0025] The walking device 31 includes a walking body 310 and walking wheels 312, which are integrally located inside the reinforcing ring 2. The walking wheels 312 move on the reinforcing ring 2 in the upper direction N. The multi-dimensional moving device 32 is arranged on the walking device 31, and includes a vertical moving component 321 and a lateral moving component 322.

[0026] The carrying handle 33 is U-shaped, and is used for carrying and moving the automatic welding device. In some embodiments, the walking device includes a pair of walking bodies 310, and the carrying handle 33 is connected to the pair of walking bodies 310, including a first end 331, a second end 332 and a connecting portion 333, the connecting portion 333 connects the first end 331 and the second end 332, and the first end 331 and the second end 332 are respectively connected to the pair of walking bodies 310.

[0027] The vertical moving assembly 321 allows the arc starting point of the welding gun to be adjusted vertically up and down. Figure 3 The vertical adjustment shown in the figure has a travel range of 35 to 55 mm, preferably about 45 mm. The lateral moving assembly 322 allows the lateral front-to-back distance of the arc starting point of the welding gun to be adjusted in the lateral direction, that is, in a direction perpendicular to the Figure 3 Paper direction adjustment, the stroke range is 35 to 55 mm, preferably about 45 mm.

[0028] The welding gun clamping device is connected to the lateral movement assembly 322 and extends to the outside of the reinforcement ring 2 for clamping the welding gun (not shown in the figure). The welding gun clamping device specifically includes a welding gun line clamp assembly 341 and a welding gun clamp assembly 342. When installing the welding gun, the welding gun line clamp assembly 341 locks the welding gun line to ensure that the welding gun line is in a stable spatial position during the welding process. When installing the welding gun, the welding gun clamp assembly 342 locks the welding gun to ensure that the welding gun is in a stable spatial position during the welding process.

[0029] The welding gun can be a bent gun or a straight gun, and the welding gun clamping device is arranged so that the horizontal angle range of the welding gun is 30-55 degrees.

[0030] The control component is at least connected to the walking wheel signal to control the automatic walking and walking trajectory of the walking device. The walking device 31 also includes gears, chains and batteries 317, and the battery 317 provides power for the shape of the automatic welding trolley. The driving mode can be four rubber wheels, the running speed can be adjusted within the range of 50 to 1000 mm / min, and the arc closing time range is 0 to 2.5s.

[0031] In some embodiments, the trolley also includes an operating panel 35 for controlling the automatic welding device. The control panel 35 includes a power switch, a parameter display window, a start / pause switch, a welding status control switch, a travel direction indicator light, a welding status indicator light, a speed adjustment switch, etc.

[0032] In order to ensure that the relative position of the trolley and the reinforcement ring does not deviate significantly, in some embodiments, the trolley further includes a suspension guide rod 37, preferably at least one pair of suspension guide rods 37. The bottom of the suspension guide rod 37 keeps in contact with the top of the reinforcement ring, so that the trolley is suspended vertically above the reinforcement ring 2. Through the suspension guide rod 37, the trolley can be suspended vertically on the upper part of the partition reinforcement ring during the horizontal lateral movement process, thereby ensuring the relative position direction of the trolley and the partition reinforcement ring.

[0033] In some embodiments, the trolley further comprises a magnetic control assembly 36 disposed on the side facing the reinforcement ring, for making the trolley close to the reinforcement ring. The magnetic control assembly 36 is the magnetic force source of the trolley, ensuring that the trolley can close to the partition reinforcement ring component during the automatic welding operation.

[0034] The following is an introduction to the working process of the car.

[0035] When using a trolley, it is preferred to first spot weld the partition 1 and the reinforcement ring 2, and then prepare for the automatic welding operation of all welds after the spot welding is completed.

[0036] Place the automatic welding trolley on the assembled partition reinforcement ring 2, with the travel wheels against the reinforcement ring 2; clamp the welding gun on the welding gun and welding gun wire clamp assembly to ensure that the welding gun and welding gun wire are firmly fixed.

[0037] Adjust the vertical movement adjustment component and the horizontal movement adjustment component, and adjust the welding gun chuck assembly to ensure that the welding gun angle meets the welding process requirements and align the end of the welding gun with the position of the weld to be welded.

[0038] The welding process parameters are adjusted in the welding machine, the welding speed and welding direction are adjusted on the control panel 35, and the automatic welding device is started on the control panel 35. The trolley automatically welds the weld of the partition reinforcement ring in the specified direction N.

[0039] After the automatic welding carriage completes one circle of welds, the touch control panel is used to stop the automatic welding device, and the automatic welding device is moved to other partition reinforcement rings to be welded using the portable handle 37 to automatically weld the next group of reinforcement rings.

[0040] Table 1 shows the main parameters of a specific embodiment of the reinforcement ring automatic welding carriage.

[0042]

[0043] The above-mentioned trolley has a simple structure and can realize fully automatic welding of irregular welds of partition reinforcement rings without manual intervention. By means of suspension guide rods and magnetic suction components to limit the relative position of the trolley and the reinforcement ring, the walking device can move along the reinforcement ring for one circle, completing the full-circle welding of reinforcement rings of various shapes. Moreover, only start and stop operations are required to complete the welding operation of irregular welds of partition reinforcement rings, and automatic welding operations of various types of reinforcement rings can be completed efficiently.
