Description

Technical Field

[0001] The utility model relates to a balancing plate for assembling a friction stir welding device, in particular to a balancing plate for assembling a friction stir welding device, and belongs to the technical field of friction stir welding device components. Background Art

[0002] Friction stir welding (FSW) is a solid-phase welding method that uses the heat generated by the friction between a high-speed rotating welding tool and the workpiece to partially melt the material to be welded. When the welding tool moves forward along the welding interface, the plasticized material flows from the front to the back of the welding tool under the action of the rotating friction force of the welding tool, and forms a dense solid-phase weld under the extrusion of the welding tool. Before welding the workpiece, the friction stir welding equipment needs to first assemble the workpiece on a balance plate.

[0003] However, conventional friction stir welding equipment only fixes the workpiece in one direction after the workpiece is assembled on the balance plate, and is not convenient for fixing the workpiece in multiple directions, resulting in poor fixation of the workpiece. Utility Model Content

[0004] The purpose of the present invention is to provide a balance plate for assembling stir friction welding equipment in order to solve the above problems. The balance plate can achieve multi-directional fixation of the workpiece during the workpiece assembly process, avoid the workpiece from moving during the welding process, and thus effectively improve the firmness of the workpiece fixation.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions: a balance plate for assembling stir friction welding equipment, comprising a placement plate, a fixed structure provided on the placement plate, the fixed structure comprising a slide plate and a first abutment plate, four slide plates slidably connected to the placement plate, a first abutment plate slidably connected to the slide plate, a second abutment plate slidably connected to the slide plate, a connecting plate fixedly connected to the first abutment plate, a guide groove provided on the connecting plate, a guide shaft fixedly connected to the second abutment plate, the guide shaft extends to the inside of the guide groove and is slidably connected to the connecting plate, four electric push rods are installed on the placement plate, the extended ends of the electric push rods are fixedly connected to adjacent slides, and four positioning plates are slidably connected to the placement plate.

[0006] Preferably, two second springs are fixedly connected to both ends of the positioning plate, and one end of the second spring is in contact with the placement plate.

[0007] Preferably, the placement plate is provided with four sliding grooves, and the positioning plate is slidably engaged with adjacent sliding grooves.

[0008] Preferably, the width of the cross section at one end of the positioning plate is greater than the width of the cross section at the other end, and the two positioning plates located on both sides of the placement plate are symmetrically arranged with respect to the middle of the placement plate.

[0009] Preferably, a first spring is fixedly connected to the first abutment plate, and the first spring is fixedly connected to the slide plate.

[0010] Preferably, the entire cross-section of the slide plate is L-shaped, and the guide groove is arranged at an angle.

[0011] Preferably, the entire cross-section of the first abutment plate is L-shaped, and the entire cross-section of the second abutment plate is T-shaped.

[0012] Preferably, the placement plate is provided with a plurality of grooves, and the placement plate is provided with a plurality of mounting holes.

[0013] The beneficial effects of the present invention are as follows: the workpieces to be welded can be placed on the placement plate in sequence, and the preliminary positioning of the workpieces can be achieved by setting four positioning plates. When multiple workpieces are placed, the two electric push rods can be started first, and the two electric push rods extend at the same time to drive the slide plate to slide on the placement plate. The movement of the slide plate will drive the first push plate to move. When the first push plate contacts one of the workpieces, the slide plate will continue to move, and the movement of the slide plate will drive the second push plate to move. During the movement, the second push plate will drive the guide shaft to move inside the guide groove. When the guide shaft moves inside the guide groove, the second push plate will slide on the slide plate toward the workpiece until the second push plate and the slide plate are tightly pressed against each other. At this time, the workpiece can be aligned with the first push plate. One side of the workpiece is fixed by the second push plate, and the other side of the workpiece is fixed by the second push plate, thereby realizing multi-directional fixation of the workpiece, effectively improving the firmness of the workpiece fixation, and when two of the workpieces are fixed, the other two first push plates and the second push plates can fix the other two workpieces under the action of the other two electric push rods, thereby realizing the fixation of all workpieces, and when the other two workpieces are fixed, the positioning plate can be made to slide on the placement plate, thereby avoiding the situation that the workpiece position cannot be completely fixed when the placement deviation occurs, thereby effectively improving the stability of use, and at the same time, the position of the workpiece can be kept unchanged after being fixed, thereby facilitating subsequent welding work.
