[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0023] Embodiment 1, referring to Figures 1-4 , an anti-abrasion fixture for ultrasonic welding, including a fixed bottom plate 1 and a triangular support block 6. An angle adjustment mechanism is fixed on the upper end surface of the fixed bottom plate 1. An elastic support component is installed on the angle adjustment mechanism. A bent plate 3 is installed on the elastic support component. A height adjustment component is arranged on the bent plate 3. The height adjustment component is connected to the bottom end of the triangular support block 6;
[0024] A triangular extension block 9 is arranged on the hypotenuse side wall of the triangular support block 6. A convex block 4 is fixed at the top end of one corner side wall of the triangular support block 6. A first air outlet hole 7 is opened in the middle of the triangular support block 6. A second air blowing hole 5 is opened in the middle of the convex block 4. An L-shaped third air blowing hole is opened on the triangular extension block 9. One end of the horizontal section of the third air blowing hole is connected with an L-shaped air blowing nozzle 8;
[0025] Both the triangular extension block 9 and the convex block 4 are integrally formed with the triangular support block 6. The upper end surface of the triangular extension block 9 is lower than the upper end surface of the triangular support block 6. The upper end surface of the convex block 4 is higher than the upper end surface of the triangular support block 6.
[0026] A groove 11 is opened in the middle of the upper end surface of the triangular support block 6. Sheepskin layers are bonded on the surfaces of the triangular support block 6, the convex block 4 and the triangular extension block 9, and holes are opened in the sheepskin layers at the positions of the groove 11 and the second air blowing hole 5;
[0027] The angle adjustment mechanism includes a damping rotating seat 17 connected to the middle of the upper end surface of the fixed bottom plate 1. The upper end of the damping rotating seat 17 is connected with a turntable 2;
[0028] The elastic support component includes two extension support plates 12 symmetrically welded on the side wall of the turntable 2. Two spring dampers 10 are symmetrically fixed on the upper end surfaces of the two extension support plates 12.
[0029] The middle of the bent plate 3 is in a convex state. The two spring dampers 10 on the two extension support plates 12 are respectively connected to the lower end surfaces of the two ends of the bent plate 3.
[0030] The height adjustment assembly includes two connecting rods 16 symmetrically and slidably inserted into the middle of the bent plate 3. The bottom ends of the two connecting rods 16 are connected with a cross bar 14. The bottom end of the triangular support block 6 is rotatably connected with an adjusting bolt 18 through a bearing. The adjusting bolt 18 is screwed to the middle of the cross bar 14. The top ends of the two connecting rods 16 are both connected with support columns 15, and the two support columns 15 are both connected to the lower end surface of the triangular support block 6.
[0031] Fixing holes 13 are formed in the fixing base plate 1. There are four fixing holes 13 and they are respectively located at the four corners of the fixing base plate 1. The fixing base plate 1 can be fixed to the working station by bolts through the fixing holes 13.
[0032] Working principle: The first air outlet hole 7, the second air blowing hole 5 and the third air blowing hole are all externally connected with air blowing pipelines. The grille to be welded is placed on the triangular support block 6. Since the convex block 4 is located on the side wall of the triangular support block 6, when the triangular support block 6 supports the grille, the highly bright black painted surface of the grille is not easily in contact with the convex block 4. During the welding process, the ultrasonic wave and heat on the grille are transmitted to the welding rib position, but because the highly bright black painted surface avoids the convex block 4, the heat generated by friction is reduced. The first air outlet hole 7, the second air blowing hole 5 and the L-shaped air blowing nozzle 8 blow air synchronously for heat dissipation to jointly improve the scalding phenomenon. And through the welded sheepskin layer, the buffering and air permeability between the painted surface of the grille and the triangular support block 6 are increased. By rotating the turntable 2, the angle of the triangular support block 6 can be adjusted to better support the grille. Through the elastic support of the set spring damper 10, the hard support or extrusion of the grille can be further reduced, and the probability of damage to the painted surface is reduced. Before use, the height of the triangular support block 6 can also be adjusted by turning the adjusting bolt 18 with a wrench, which improves the practicability.
[0033] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
