[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] See also Figure 1-6 The utility model provides a technical solution: an ultrasonically welded PEEK gas cylinder structure, including a main bottle body 1, an upper cover 2, a Z-shaped cross section 3, a docking block 4, a convex ring 5, a convex point 6, a welding rib 1 7, a connecting ring 8, an inclined block 9, a welding rib 2 10, and a convex point 2 11.
[0031] Example 1
[0032] The ultrasonically welded PEEK gas cylinder structure is provided with a welding structure, which can automatically align with the main body 1 and the Z-shaped section 3 at the lower end of the upper cover 2 through the convex ring 5, specifically:
[0033] The upper end of the main body 1 is a welding section, and also includes an upper cover 2. The lower surface of the upper cover 2 is set as a Z-shaped section 3. The main body 1 is connected with a welding structure. The welding structure can generate a gap between the main body 1 and the upper cover 2 through a docking block 4 corresponding to a convex point 6. The welding structure includes a docking block 4. The lower surface of the upper cover 2 is fixedly installed with a docking block 4. A convex ring 5 is fixedly arranged on the upper surface of the main body 1, and the height of the convex ring 5 and the plane formed by the upper surface of the main body 1 correspond to the Z-shaped section 3 at the lower end of the upper cover 2. A convex point 6 is also arranged on the upper surface of the main body 1. The upper surface of the convex point 6 is connected to the lower end of the docking block 4, and the inner surface of the convex ring 5 is connected to the outer surface of the Z-shaped section 3. A welding rib 7 is embedded and fixedly installed on the upper surface of the convex ring 5. The convex point 6 is located on the inner side of the convex ring 5, and the docking block 4 is set as a triangular ring structure.
[0034] When using ultrasonic welding for the PEEK gas cylinder, the ultrasonic welding head designed by finite element simulation software should be installed on the ultrasonic welding equipment first, and the appropriate shape and size of the welding head should be selected to avoid stress concentration. Then, the lower end fixing tooling should be customized according to the welding product. During welding, the main bottle body 1 is placed in the customized fixing tooling, and then the upper cover 2 is docked with the main bottle body 1. During docking, the outer surface of the Z-shaped section 3 on the lower surface of the upper cover 2 will contact the inner surface of the convex ring 5 fixedly connected to the upper surface of the main bottle body 1, so that the upper cover 2 and the main bottle body 1 can be automatically aligned. At this time, the docking connection of the Z-shaped section 3 The lower end of the block 4 will correspond to the convex point 6 on the upper surface of the main bottle body 1. Through the contact of the docking block 4, a gap of 0.15-0.2mm is made between the contact surfaces of the upper cover 2 and the main bottle body 1. Then welding begins. The welding rib 7 embedded and fixed on the upper surface of the convex ring 5 will be melted. At the same time, the docking block 4 is also set to be a welding rib material, so the docking block 4 is also melted. Then the upper cover 2 will be pressed down, so that the gap is fixed by the melted material. The convex point 6 on the upper surface of the main bottle body 1 makes the upper surface of the main bottle body 1 a textured surface, which improves the quality of welding and makes the welding more firm.
[0035] Example 2
[0036] The ultrasonically welded PEEK gas cylinder structure is also provided with a reinforcement structure, which can prevent internal overflow through the inclined block 9 and form a weld with the inner surface of the upper cover 2, specifically:
[0037] The main bottle body 1 is also connected to a reinforcement structure, which can receive welding overflow and be reinforced and connected to the inner wall surface of the upper cover 2 through an inclined block 9. The reinforcement structure includes a connecting ring 8, which is fixedly installed on the inner wall surface of the main bottle body 1, and an inclined block 9 is fixedly installed on the upper surface of the connecting ring 8. A welding rib 10 is installed on the inclined surface of the inclined block 9, and a convex point 11 is correspondingly arranged below the welding rib 10. The convex points 11 are installed on the inclined surface of the inclined block 9 at equal intervals, and the upper surface of the connecting ring 8 is flush with the upper surface of the main bottle body 1;
[0038] Furthermore, the butt joint of the Z-shaped cross section 3 can eliminate external overflow during welding. Since the upper surface of the connecting ring 8 is flush with the upper surface of the main bottle body 1, the molten overflow of the butt joint block 4 will reach the upper surface of the connecting ring 8. At the same time, the welding rib 2 10 installed on the inclined surface of the inclined block 9 on the upper surface of the connecting ring 8 will also be melted, so that the inclined surface of the inclined block 9 and the inner wall surface of the upper cover 2 are welded through the welding rib 2 10, making the connection more stable. In addition, the inclined surface of the inclined block 9 is also provided with a convex point 2 11, and the rough texture can make the welding quality better.
[0039] Working principle: When using the ultrasonically welded PEEK gas cylinder structure, the welding structure can make the welding of the main bottle body 1 and the upper cover 2 more stable through the correspondence between the docking block 4 of the upper cover 2 and the convex point 6, and the reinforcement structure can receive the welding overflow and reinforce the connection with the inner wall surface of the upper cover 2 through the inclined block 9, thereby increasing the overall practicality.
[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
