[0001] The invention relates to welding equipment and belongs to the technical field of welding. Background Art

[0002] At present, before welding, the welded parts need to be manually positioned, and then the welded parts are manually welded with a handheld welding gun head. With the above solution, it is easy to have inaccurate positioning before welding, long positioning time, and low positioning efficiency. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide welding equipment, which solves the problems of inaccurate positioning before welding, long positioning time and low positioning efficiency in manual positioning of welded parts and manual welding.

[0004] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0005] The welding equipment comprises a box body, a movable wheel arranged at the bottom of the box body and a frame body arranged inside the box body, wherein a telescopic adjustment tube, a welding gun head and a clamping mechanism are respectively arranged inside the box body, and the telescopic adjustment tube, the welding gun head and the clamping mechanism are all located at the outer top of the frame body, the telescopic adjustment tube is slidably connected to the top of the box body, the welding gun head is arranged inside the telescopic adjustment tube and at the top of the clamping mechanism, and a transmission mechanism for driving the clamping mechanism is also arranged inside the box body.

[0006] As a preferred example, the inner top of the box body is fixedly connected with a connecting rib, and there are two connecting ribs. The two connecting ribs are arranged in parallel at the inner top of the box body, and the two ends of each connecting rib are respectively fixedly connected to the two opposite inner walls of the box body, and a sliding groove is provided on the side wall of one of the connecting ribs, and the top of the telescopic adjustment tube is slidably connected to the sliding groove through a slider, and the top of the box body is also provided with a through hole for placing the welding gun head in the telescopic adjustment tube.

[0007] By adopting the above scheme, the telescopic sleeve can slide on the connecting rib with the assistance of the slider, so that the welding gun head can move both vertically on the telescopic adjustment tube and horizontally on the connecting rib, thereby realizing the welding gun head to perform multi-directional welding operations on the steel bars and the workpiece to be welded.

[0008] As a preferred example, the telescopic adjustment tube includes a fixed tube and a telescopic tube, and the top side wall of the fixed tube is slidably connected to the slider, the top of the telescopic tube is movably sleeved on the fixed tube, and the fixed tube is provided with a limit block for limiting the movement of the telescopic tube.

[0009] By adopting the above scheme, the telescopic tube can move up and down in the fixed tube and be positioned by the limit block, so that the welding gun head can move vertically by the telescopic tube moving up and down in the fixed tube, and the welding gun head can perform vertical welding operations on the steel bars and the workpiece to be welded.

[0010] As a preferred example, the clamping mechanism includes a rotating table, an L bracket, a cylinder fixing seat, a linear bearing fixing seat, a linear bearing, a positioning block, an abutment block, a first cylinder, a second cylinder, a wear-resistant plate, an adjustment block and a pressure plate. The rotating table is arranged inside the box, and the wear-resistant plate is fixed on the rotating table. There are three adjustment blocks, and the three adjustment blocks are fixed on the wear-resistant plate in a triangular shape. The bottom of the L bracket is also fixed on the rotating table. The linear bearing fixing seat, one end of the first cylinder fixed end and the second cylinder fixed end are respectively fixed on the top and two side walls of the L bracket, and the other end of the first cylinder fixed end is fixed on the cylinder fixing seat. The positioning block is rotatably sleeved on the cylinder fixing seat, and the telescopic end of the first cylinder is hinged to the positioning block.

The telescopic end of the second cylinder is fixed to the pressure plate, and the pressure plate abuts against the abutment block.

[0011] Using the above scheme, the main working steps of the clamping mechanism are as follows:

[0012] First, place the steel bar and the workpiece to be welded vertically, then move the linear bearing so that the abutment block abuts against one side of the steel bar, and then start the first cylinder. When the first cylinder is extended or retracted, the positioning block is driven to deflect, and the positioning block fixes the steel bar through the opening on the abutment block, that is, the positioning block contacts the other side of the steel bar, that is, the side opposite to the abutment block. Finally, start the second cylinder. The extension and retraction of the second cylinder drives the movement of the pressure plate until one side of the pressure plate abuts against the abutment block.

[0013] As a preferred example, the transmission mechanism includes a U-shaped bracket, a reducer, a main gear, a slave gear, and a rotating support table. The U-shaped bracket is fixed inside the frame, and the main gear and the slave gear are rotatably connected to the top of the U-shaped bracket through a rotating shaft, and are both located at the outer top of the frame.

[0014] Using the above scheme, the operation steps of the transmission mechanism are as follows:

[0015] First, start the reducer to drive the main gear to rotate, and then drive the slave gear to rotate, and then drive the rotary support table to rotate, and then drive the rotating table to rotate, and then the steel bars and the workpiece to be welded on the rotating table are welded while the rotating table rotates.

[0016] As a preferred example, a wire feeder for conveying welding wire used by the welding gun head inside the box is also provided on the outside of the box.

[0017] The above scheme is adopted to provide wire feeding for the welding operation between the steel bar and the workpiece to be welded by using the welding gun head.

[0018] As a preferred example, a movable door is slidably connected to one side wall of the box body, and two third cylinders are fixedly connected to the bottom end of an inner side wall of the box body. The telescopic end of each third cylinder is respectively fixed to the bottom of the movable door.

[0019] The purpose of adopting the above scheme is to utilize the extension and retraction of the third cylinder to realize the closing and opening of the movable door on the box body, so as to observe and maintain the clamping condition of the clamping mechanism inside the box body, the welding condition of the welding gun head and the rotation condition of the transmission mechanism.

[0020] The beneficial effects of the present invention are as follows: the present invention mainly adopts a telescopic adjustment tube and the telescopic adjustment tube slides in a slide groove on the connecting rib of the box body through a slider, so that the welding gun can move in the vertical direction and the horizontal direction relative to both the steel bar and the workpiece to be welded. In addition, with the assistance of the clamping mechanism and the transmission mechanism, both the steel bar and the workpiece to be welded can be fixed on the rotating table and rotated relative to the box body, so that the welding gun head can be used to perform multi-directional welding operations on the rotating steel bar and the workpiece to be welded, thereby achieving the effect of semi-automatic positioning and clamping the steel bar to be welded and semi-automatic welding compared to manual positioning and hand-held welding, ultimately improving the welding positioning accuracy, shortening the positioning time, and improving the positioning efficiency.
