Technical Field
[0001] This utility model relates to the technical field of welding short and long thin materials, and in particular to a high-efficiency precision welding fixture for double thin materials. Background Technology
[0002] The structure of a certain thin material is as follows Figures 1-2 As shown, it includes a thin material body A1 and a bending plate A2, which are fixedly connected to the thin material body A1. The bending plate A2 is bent to the left, and a through hole A3 is provided at the upper end of the thin material body A1. The structure of a long thin material is as follows... Figures 3-4 As shown, it includes a thin material body B4 and a bending plate B5, which are fixedly connected to the thin material body B4. The bending plate B5 is bent to the right, and a through hole B6 is provided at the lower end of the thin material body B4.
[0003] The process requires welding a short, thin bending plate A2 onto a long, thin bending plate B5 to obtain the desired product. The product structure is as follows: Figures 5-6 As shown. The method for welding short, thin materials together with long, thin materials in a certain workshop is:
[0004] S1. The worker takes out a short thin material and a long thin material. The worker places the bending plate A2 of the short thin material against the bending plate B5 of the long thin material, and then adjusts the position of the short thin material so that the bending plate A2 is exactly at the designated position of the bending plate B5, so as to achieve the positioning of the two thin materials.
[0005] S2. The worker points the laser head of the laser welding machine toward the bent plate B5. After the laser beam emitted by the laser head irradiates the bent plate B5, the direction of the laser beam is as follows: Figure 5 As shown by the middle arrow, a weld point 7 is formed on the bending plate B5, thereby welding the short, thin bending plate A2 onto the long, thin bending plate B5, thus achieving the welding of the two thin materials and obtaining the desired product.
[0006] S3. Workers can repeat steps S1 to S2 to continuously weld and produce multiple required products.
[0007] However, although the method used in the workshop can weld the short, thin bending plate A2 to the designated position of the long, thin bending plate B5, the following technical defects still exist in actual operation:
[0008] I. In step S2, when the laser beam emitted by the laser head irradiates the long, thin material bending plate B5, the bending plate B5 is heated and warps to the left. However, the process requires that the long, thin material bending plate B5 should not deform after welding, thus reducing the welding quality.
[0009] II. In steps S1 to S2, only one product can be welded and produced by one positioning, which results in a long time required to produce the required number of products. This undoubtedly reduces the welding efficiency of short and thin materials and long and thin materials.
[0010] Therefore, there is an urgent need for a welding fixture that can greatly improve the welding efficiency of short and thin materials and long and thin materials. Utility Model Content

[0015] The diameter of the positioning pin B is equal to the diameter of the through hole B in the long thin material.
[0016] The diameter of the guide post is equal to the diameter of the positioning hole.

[0041] like Figures 7-12 As shown, a high-efficiency precision welding fixture for double thin materials includes a first plate 8, which includes a flat plate 9 and a protruding plate 10 integrally connected to the flat plate 9. A first inclined surface 11 is formed between the flat plate 9 and the protruding plate 10. A first magnet 12 is fixedly installed in the first inclined surface 11 at both ends. A plurality of inclined holes 13 penetrating the right end face of the protruding plate 10 are opened in the first inclined surface 11 between the two first magnets 12. The inclined holes 13 are inclined to the right and downward. The left end face of the flat plate 9 is edged with... Multiple positioning pins A14 are fixed in the longitudinal direction of the plate 10. The diameter of the positioning pins A14 is equal to the diameter of the through hole A3 of the short thin material. The multiple positioning pins A14 are respectively opposed to multiple oblique holes 13. Multiple positioning pins B15 are fixed along the length direction on the left end face of the convex plate 10. The diameter of the positioning pins B15 is equal to the diameter of the through hole B6 of the long thin material. Guide posts 16 are fixed on the left end face of the convex plate 10 at both ends. The diameter of the guide posts 16 is equal to the diameter of the positioning hole 24.
[0042] The welding fixture also includes a second plate 17, which includes a strip plate 18 and a pressure plate 19 fixedly connected to the strip plate 18. A second inclined surface 20 is formed between the pressure plate 19 and the strip plate 18. The first inclined surface 11 is parallel to the second inclined surface 20. A second magnet 21 is fixedly provided in the second inclined surface 20 at both ends. The strip plate 18 has a plurality of receiving holes A22 along its length, which correspond to each positioning pin A14. The pressure plate 19 has a plurality of receiving holes B23 along its length, which correspond to each positioning pin B15. The pressure plate 19 also has positioning holes 24 at both ends, which are respectively vertically opposite to the two second magnets 21.
[0043] A blind groove is formed in the first inclined surface 11, and the first magnet 12 is fixed in the blind groove; a blind groove is formed in the second inclined surface 20, and the second magnet 21 is fixed in the blind groove.
[0044] The working process of this utility model is as follows:
[0045] S1, the worker takes out a... Figures 3-4 The long thin material is shown, with the through hole B6 of the long thin material fitted onto the positioning pin B15 of the first plate 8, and the thin material body B4 of the long thin material is supported on the protruding plate 10 of the first plate 8, and the bending plate B5 of the long thin material is matched with the first inclined surface 11 of the first plate 8.
[0046] S2, The worker takes out a... Figures 1-2 The short thin material is shown. The through hole A3 of the short thin material is fitted onto the positioning pin A14 of the first plate 8, and the thin material body A1 of the short thin material is supported on the flat plate 9 of the first plate 8. The bending plate A2 of the short thin material is placed against the bending plate B5 of the long thin material. Then the position of the short thin material is adjusted so that the bending plate A2 is exactly at the designated position of the bending plate B5, thereby realizing the positioning of the first long thin material and the first short thin material.
[0047] S3. By repeating steps S1 to S2 multiple times, workers can achieve the positioning of multiple long thin materials with multiple short thin materials.
[0048] S4. The worker places the two positioning holes 24 of the second plate 17 onto the two guide posts 16 of the first plate 8, respectively. Figure 13 As shown, the two second magnets 21 of the second plate 17 are attracted to the two first magnets 12 of the first plate 8, respectively. Figure 14 As shown, the second plate 17 is adsorbed and fixed onto the first plate 8. At this time, the short, thin bending plate A2 and the long, thin bending plate B5 are pressed between the first inclined surface 11 and the second inclined surface 20. Figure 15 As shown;
[0049] S5. The worker positions the laser head of the laser welding machine toward the oblique hole 13 of the first plate 8. After the laser beam emitted by the laser head irradiates the bent plate B5, the direction of the laser beam is as follows: Figure 15 As shown by the middle arrow, weld point 7 is formed on the bent plate B5, thereby welding the short, thin bent plate A2 onto the long, thin bent plate B5, thus achieving the welding of the two thin materials, resulting in the first... Figures 5-6 The product shown;
[0050] S6. Workers can repeat step S6 multiple times to obtain multiple products.
[0051] S7. Product Removal: The worker removes the second plate 17 from the first plate 8 and then removes the welded product.
[0052] In steps S1 to S34, this fixture, through the cooperation of the first plate 8 and the second plate 17, can fix multiple long thin materials and multiple short thin materials. In steps S5 to S6, by sequentially pointing the laser head of the laser welding machine towards each oblique hole 13, the bent plate A2 of the short thin material can be welded onto the bent plate B5 of the long thin material, thereby obtaining multiple products. Therefore, this fixture enables the production of multiple products in a short time, thus greatly improving the welding efficiency of short and long thin materials.
[0053] Furthermore, as can be seen from step S4, since the bent plate A2 of the short thin material and the bent plate B5 of the long thin material are pressed between the first inclined surface 11 and the second inclined surface 20, the positions of the bent plate A2 and the bent plate B5 are always fixed. Therefore, when the laser beam emitted by the laser head irradiates the bent plate B5 of the long thin material, the bent plate B5 will not warp or deform due to heat, thereby greatly improving the welding quality.
