Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an arc welding robot welding gun capable of multi-angle welding. Background Art

[0002] A welding robot is an industrial robot engaged in welding, and is mainly used in the field of industrial automation. A Chinese utility model patent with the announcement number CN217991414U discloses a gantry-type welding robot with multi-angle adjustment, which can drive the driving gear to mesh with the driven gear to rotate through a travel motor arranged in the travel shell, and with the cooperation of the transmission rod, the travel wheel can rotate in the connecting groove, thereby driving the travel shell to move horizontally, so that the horizontal position of the welding head can be adjusted, which is convenient for welding workpieces in different positions.

[0003] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: in the above-mentioned structure, the position of the welding head can move back and forth under the action of the walking wheel, which can weld longer workpieces. When the width of the workpiece is large and the edge of the workpiece is far away from the position of the welding head, the welding head cannot move forward and backward, so the welding operation cannot be performed. At this time, the workpiece needs to be moved accordingly. For this reason, we designed an arc welding robot welding gun capable of multi-angle welding. Utility Model Content

[0004] In order to solve the technical problem that a welding head cannot move forward and backward and thus cannot weld a workpiece with a larger width, the utility model provides an arc welding robot welding gun capable of multi-angle welding.

[0005] The utility model is implemented by the following technical scheme: an arc welding robot welding gun capable of multi-angle welding, comprising a welding table, a deflection ring is rotatably installed on the outer ring surface of the welding table, a mounting swivel is fixed above the deflection ring, an adjusting cylinder is installed on the side of the mounting swivel away from the welding table, a mounting frame is connected to the push rod of the adjusting cylinder, and the mounting frame is slidably placed above the welding table, a four-axis manipulator is slidably arranged on the side of the mounting frame away from the adjusting cylinder, and a welding gun is installed on the four-axis manipulator.

[0006] As a further improvement of the above scheme, a plurality of meshing teeth distributed in a ring shape are arranged on the outer ring surface of the deflection ring, the deflection ring is meshed with the driving gear through the meshing teeth, and the driving gear is installed on the output shaft of the reduction motor. The deflection ring can rotate 360 ​​degrees under the action of the reduction motor and the driving gear, thereby causing the four-axis manipulator to rotate accordingly, so that the workpiece on the welding table can be welded.

[0007] As a further improvement of the above scheme, guide holes are formed through the front and rear of the mounting swivel seat, a guide rod is slidably sleeved in the guide hole, and the guide rod is fixed to the mounting frame on the inner side, and the length of the guide rod is greater than the maximum stroke of the adjusting cylinder. The design of the adjusting cylinder can make the four-axis manipulator close to the center of the welding table, and thus can weld workpieces of various sizes, and the design of the guide rod makes the movement of the mounting frame more stable.

[0008] As a further improvement of the above solution, a lifting groove is provided on the surface of the mounting frame on one side facing away from the mounting swivel seat, a lifting screw is rotatably mounted in the lifting groove through a bearing, and the upper part of the lifting screw is connected to the output shaft of the lifting motor through a coupling;

[0009] The four-axis manipulator is provided with a lifting screw seat, which is slidably placed in the lifting slot and is threadedly connected to the lifting screw rod. The rotation of the lifting motor can rotate the lifting screw rod, and then the lifting screw seat can move up and down. The height of the four-axis manipulator can be changed according to needs, and is suitable for welding workpieces of various heights.

[0010] As a further improvement of the above scheme, a moving seat is installed under the mounting frame, and a plurality of evenly distributed bull's eye balls are embedded in the interior of the moving seat, and the bull's eye balls are rolled under the moving seat, and the bottom end of the bull's eye balls is placed under the moving seat, and the bull's eye balls are in rolling contact with the upper surface of the welding table, and the moving seat does not directly contact the welding table, thereby facilitating the movement of the mounting frame.

[0011] As a further improvement of the above solution, the upper surface of the deflection ring is on the same plane as the upper surface of the welding table, which facilitates the mounting frame to deflect and move linearly on the welding table through the bull's eye ball.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model sets a 360-degree rotating deflection ring on the outer ring of the welding table, fixes the mounting swivel seat on the deflection ring, and places the mounting frame with the four-axis manipulator on the front side of the mounting swivel seat and can rotate with it, so that the four-axis manipulator and the welding gun are at the nearest position to the welding position of the workpiece, which is convenient for subsequent welding;

[0014] 2. The mounting frame is placed above the welding table through a moving seat and a bull's eye ball sliding, and cooperates with the setting of the adjusting cylinder to enable the four-axis manipulator and the welding gun to move back and forth, so that welding operations can be performed at any position on the welding table.
