Description

Technical Field

[0002] In the field of construction industry, precast concrete parts are often used. Precast concrete parts refer to concrete products that are processed and produced in a standardized and mechanized manner in a factory. Precast concrete parts are made of steel bars and concrete. When making precast concrete parts, the internal steel bars need to be placed and welded first, and then the welded steel bars are placed in a mold, and concrete is poured into the mold. After forming, the precast concrete parts can be obtained. When welding steel bars, welding robots are used in the prior art. Before welding by the welding robot, the steel bars need to be placed in a fixed position and wait for the welding robot to weld. However, the operator only places the steel bars on the platform, and there is no other device to stabilize the steel bars on the platform. When the steel bars are hit on the platform, the steel bars will deviate from the original placement position, that is, there will be a positional deviation, which will cause the placement position of the steel bars to not accurately correspond to the welding position of the welding robot, so that it is easy to cause missed welding or wrong welding points. At this time, it is necessary to perform repair welding, which reduces the efficiency of welding. Utility Model Content

The following is a description of the embodiments of the present invention based on its overall structure.

[0031] Figure 1 This is a schematic diagram of the overall structure of the welding device provided by the utility model. Figure 1 The welding device comprises a plurality of welding units 1, a track 4 and a welding robot 2.

In an embodiment of the utility model, the track 4 is a circular track, and the plurality of welding units 1 are arranged on the track 4 in a circular array.

[0032] See also Figure 1 The utility model shows three welding units 1. A welding station is arranged on the track 4 and directly in front of the welding robot 2. The welding station corresponds to the welding position of the welding robot 2. The left side of the welding station is the rear station, and the right side of the welding station is the front station. When welding the steel bars 3, the welding unit 1 to be welded is moved to the welding station, and the welding robot 2 welds the steel bars 3. After the welding of the steel bars 3 on the welding station is completed, the welding unit 1 on the welding station is transported to the rear station. At this time, the welding unit 1 to be welded on the front station is moved to the welding station for welding, thereby realizing automated welding.

[0033] In some other embodiments, the track 4 can be a straight track. When the track 4 is a straight track, a welding station is also arranged directly in front of the welding robot 2, the rear station is on the left side of the welding station, and the front station is on the right side of the welding station.

[0034] Figure 2 This is a schematic diagram of the structure of the welding unit provided by the utility model. Figure 2The welding unit 1 includes a support assembly 10 and a welding platform 11. The top of the support assembly 10 is horizontally connected to a first fixing rod 12, and the first end of the first fixing rod 12 is vertically connected to the first end of the second fixing rod 13. The welding platform 11 is connected to the second end of the first fixing rod 12 and the second end of the second fixing rod 13, so that the welding platform 11 is tilted on the support assembly 10; a plurality of placement bars 14 arranged perpendicular to each other are arranged in the welding platform 11, and the two ends of each placement bar 14 are respectively connected to the inner side surface of the welding platform 11, and each placement bar 14 is provided with a slot 140, and the slot 140 is used to place steel bars; the bottom of the support assembly 10 is connected to a base 15, and the base 15 is provided with screws 16, and the screws 16 are used to connect the base 15 to the track.

[0035] Specifically, when welding steel bars, the steel bars are placed in a cross shape, so the placement bars 14 are arranged perpendicular to each other to accommodate the placement of the steel bars.
