Description

Technical Field

[0001] This utility model relates to the field of automatic welding equipment technology, and in particular to a bottom plate feeding mechanism and welding machine. Background Technology

[0002] Warehouse racks are typically constructed from uprights and beams. The bottom of each upright is welded with a base plate, which contacts the ground to provide stability. These base plates are usually made of thin sheet metal, only 1mm thick, and are manually welded to one end of the upright. Traditional manual welding methods are inefficient and lack accuracy in weld placement.

[0003] Existing technology provides an automatic conveying device for hanging plates, which can deliver stacked hanging plates one by one to the welding position by punching, and then the welding is completed by the corresponding welding gun. This type of device has the following problems when used for welding base plates: because the base plates are thin and have burrs, when punching the base plates at the punching position, they are easily jammed by adjacent base plates, resulting in punching failure.

[0004] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0031] The punch 27 and the punch cylinder 28 are located on the left side of the second bracket 24, above the material trough 23. The driving end of the punch cylinder 28 is downward and is equipped with a punch plate. The punch is located on one side of the punch plate. When the bottom piece reaches the punch position, the driving end of the punch cylinder 28 extends downward and the punch pushes the bottom piece to the welding position.

[0032] The base piece mold 29 is located below the first support 21 and can serve as a support for the first support 21. On the right side of the base piece mold 29, which is the welding position, a second magnetic positioning component is provided to attract the punched base piece.

[0033] Specifically, a gap is reserved on the first bracket 21, which is larger than the gap between the stamp and the base piece, so that the stamp will punch the base piece to the welding position.

[0034] A counterweight is also placed in the material trough 23. The counterweight is placed at the left end of the stacked base pieces. When the patch cylinder 22 is working, it pushes the counterweight and the base pieces together to move towards the second bracket 24. The counterweight and the first magnetic positioning component are used to ensure that the stacked base pieces are stable and do not tilt.

[0035] Specifically, both the first and second magnetic positioning components are magnets.

[0036] Please see Figures 1 to 3 The first embodiment of this utility model also provides a base plate welding machine, including: a frame 1, the aforementioned base plate feeding mechanism 2, a welding gun driving mechanism 3, and a clamping cylinder 4. A first support 21 is disposed on the left side of the working surface of the frame 1, the welding gun driving mechanism 3 is disposed on the right side of the second support 24, and a welding gun 38 is disposed at its driving end.

[0041] The welding torch mounting base 37 is located on the right side of the third movable plate 35 and is used to hold the welding torch.

[0042] There are three weld points between the column and the base plate. The welding gun drive mechanism completes the welding of the three weld points in the following sequence:

[0043] When all cylinders retract, they are at the upper right welding point. After completing the upper right welding point, the first layer cylinder 36 moves forward and the vertically adjustable cylinder 32 moves downward to weld the lower middle point. Then, the middle layer cylinder 34 moves forward and the vertically adjustable cylinder 32 moves upward to weld the upper left welding point. After completing the three welding points, they retract.

[0044] To ensure accurate alignment between the column and the base plate, a column positioning plate 7 and a side clamping cylinder 8 are also provided.

[0045] The column positioning plate 7 and the side clamping cylinder 8 are symmetrically arranged on the working surface. When the column is placed, it is placed against the column positioning plate 7, and then the top clamping cylinder 4 and the side clamping cylinder 8 clamp the column into place, so that the left end of the column is close to the base plate, and then the welding gun drive mechanism 3 completes the welding.
