Technical Field

[0001] The utility model belongs to the technical field of laser beam welding processing for IPC classification B23K26 / 00, and in particular relates to a structural innovation and improvement technology of a self-controlled welding auxiliary weld positioning tracking laser equipment mounting bracket device. Background Art

[0002] There are many types of common automatic welding equipment, but the welding guidance technologies are different. The number of high-precision welding workpieces is increasing day by day. Some processing tasks have dense welds, high precision, and very small sizes, which have high requirements for welding operations.

[0003] In the prior art, some welding surfaces are not stable, mostly due to deficiencies in the seam tracking of the welding robot during welding, which affects the stability of the weld. When welding, the welding gun needs to be aimed at the position where welding is required. The existing adjustment methods are mostly manual, and the position and shape of the weld cannot be monitored in real time, which reduces the accuracy of the welding work.

[0005] Patent application 202123206301.4 relates to an argon arc welding laser weld tracking and adjustment device, including a mounting base, on which a welding gun and a laser vision tracking sensor are arranged, and the laser vision tracking sensor is installed on the mounting base through the cooperation of a second base, a second mounting plate and a third mounting plate, so as to realize the adjustment of the horizontal lateral direction, vertical longitudinal direction and detection angle in a small space, and the welding gun is detachably mounted on the mounting base through the cooperation of a first mounting base, a first mounting plate, a mounting block and a fixed block, and the laser vision tracking sensor is installed separately from the welding gun, thereby reducing the weight of the welding gun.

[0006] In the prior art, the consistency of workpieces cannot be guaranteed in the production of automatic welding workpieces, resulting in the displacement of the welding seam position, insufficient strength, and unqualified products. Improved weld tracking technology still needs to be continuously improved. Utility Model Content

[0008] To this end, the utility model comprises: a rotating seat, an additional seat and a clamp. The rotating seat and the additional seat both have adjacent wing plate structures bent at right angles; the clamp comprises two mutually buckled clamping blocks with corresponding clamping grooves, the clamp is installed on one of the wing plates of the rotating seat, and the other wing plate of the rotating seat is hingedly connected to one wing plate of the additional seat.

[0009] The rotating seat is composed of a first mounting plate and a second mounting plate which are perpendicular to and connected to each other; a first rotating hole is opened in the middle of the first mounting plate, and a first arc-shaped adjustment groove is opened on at least one side edge of the first mounting plate.

[0010] The mounting seat is composed of a third mounting plate and a fourth mounting plate which are perpendicular and connected to each other; a second mounting hole is opened on the third mounting plate, a second screw connection hole is opened in the middle of the fourth mounting plate, and a first pin hole is opened on the edge of the fourth mounting plate.

[0012] A fourth screw hole and a second pin hole are correspondingly arranged on the first clamping block of the clamp.

[0013] Furthermore, to achieve the above purpose, the utility model is configured as follows: a first mounting hole is provided on the second mounting plate. Alternatively, a third rotating hole and a second arc-shaped adjustment groove are provided on the second mounting plate of the rotating seat.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By installing a screw-on seat-additional seat-clamp as an adjustable combined bracket for installing a laser tracker on the welding gun, the installation and adjustment structure is reasonably designed to provide stable support, reduce vibration and offset of the equipment during use, and improve the convenience of adjusting the angle and position of the laser tracker. The adjustment range is large, and the position and shape changes of the weld can be monitored in real time, thereby improving the accuracy of weld positioning. It occupies little space and is easy to install without significantly increasing the overall weight of the welding gun support structure. BRIEF DESCRIPTION OF THE DRAWINGS
