Description

Technical Field

[0001] The utility model relates to the field of ultrasonic welding technology, in particular to an integrated ultrasonic welding head for welding circular products. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic waves. In addition to being used in factories, welding can also be performed in a variety of environments, such as outdoors, underwater and in space. Welding can be dangerous to operators wherever it occurs, so appropriate protective measures must be taken when welding. Possible injuries to the human body caused by welding include burns, electric shock, vision damage, inhalation of toxic gases, excessive ultraviolet radiation, etc. Ultrasonic welding is also a type of welding.

[0003] The ultrasonic welding head includes a mother welding head and a sub-welding head. In the existing ultrasonic welding head, the mother welding head and the sub-welding head are split designs and are installed together by bolts. The integrity is poor, which affects the overall structural strength. Moreover, the existing sub-welding head is rectangular. When welding circular products, both sides of the product need to be welded separately, which makes the welding process more troublesome. Moreover, due to the influence of the shape of the sub-welding head, the welding part needs to have a certain distance from the product, and the welding effect is poor. Therefore, it is necessary to make further improvements to the existing welding head structure. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide an integrated ultrasonic welding head for welding circular products, which can effectively solve the problems of poor integrity of the existing ultrasonic welding heads, complicated welding process for circular products, and poor welding effect.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An integrated ultrasonic welding head for welding circular products includes an integrally formed mother welding part and a sub-welding part; the sub-welding parts are provided in two pieces, and the two sub-welding parts are integrally formed downward on the left and right sides of the mother welding part. The sub-welding parts are arranged on the left and right sides, and each sub-welding part is an arc-shaped setting that fits the product. A clearance groove that matches the product is formed between the two sub-welding parts.

[0007] As a preferred solution, the upper end surface of the mother welding part is provided with a mounting hole for matching with the outside, and the mounting hole is located in the middle of the mother welding part.

[0008] As a preferred solution, a through groove is provided on the mother welding part, which passes through the front and rear end surfaces of the mother welding part, and the through groove is extended up and down.

[0009] As a preferred solution, a reinforcement portion is integrally formed at the connection between the sub-weld portion and the mother weld portion, and the outer side wall of the reinforcement portion has an arc-shaped connection surface, and the upper and lower ends of the connection surface are respectively connected to the mother weld portion and the sub-weld portion.

[0010] As a preferred solution, a welding head is further included; the welding head extends downward from the lower end surface of the sub-welding portion as a whole, and a plurality of welding heads arranged at intervals are provided at the lower end of each sub-welding portion.

[0011] As a preferred solution, the welding heads are arranged at intervals along the extension direction of the lower end surface of the sub-welding portion, and the welding heads are arranged in multiple rows horizontally.

[0012] As a preferred solution, the welding heads in the two adjacent rows are arranged in a front-to-back staggered manner.

[0013] As a preferred solution, the diameter of the welding head gradually decreases from top to bottom.

[0014] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0015] The two sub-welds are integrally formed downward on the left and right sides of the mother weld, and the sub-welds are arranged left and right. Compared with the existing bolt fixing method, the one-piece forming method has better integrity and higher overall structural strength. In addition, each sub-weld is configured to fit the arc shape of the product, and a clearance groove that matches the product is formed between the two sub-welds, so that the product can be given a position through the clearance groove during welding, thereby realizing welding on both sides of the product at the same time. At the same time, the arc shape can make the welding position of the sub-weld better fit the product, and the welding effect is also better.

[0016] In order to more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the present invention, which includes an integrally formed mother welding part 10, a sub-welding part 20 and a welding head 30.

[0026] The sub-weld parts 20 are arranged in two parts, and the two sub-weld parts 20 are integrally formed downward on the left and right sides of the main weld part 10. The integrally formed structure makes the overall integrity of the welding head better, while ensuring the overall structural strength. During the welding process, the sub-weld parts 20 can avoid the positional misalignment between the sub-weld parts 20 and the main weld part 10, thereby ensuring the service life of the welding head. The sub-weld parts 20 are arranged on the left and right sides, and each sub-weld part 20 is an arc-shaped setting that fits the product. A clearance groove 201 that matches the product is formed between the two sub-weld parts 20; during welding, the product can be placed in the clearance groove 201, so that the two sub-weld parts 20 can weld both sides of the product at the same time, making the welding process more convenient. In addition, the arc shape makes the sub-weld part 20 fit more closely with the outer periphery of the product, and the welding position will be closer to the product, resulting in a better welding effect. At the same time, the arc-shaped sub-weld part 20 can make the structural strength of the sub-weld part 20 itself higher, preventing the sub-weld part 20 itself from being damaged.

[0027] In this embodiment, the upper end surface of the mother welding part 10 is provided with a mounting hole 101 for mating with an external part. The mounting hole 101 is located in the middle of the mother welding part 10, and the mother welding part 10 is mounted by mating with the mounting hole 101 and the external mounting part. The mother welding part 10 is provided with a through groove 102 that passes through the front and rear end surfaces of the mother welding part 10. The through groove 102 is extended up and down. The through groove 102 is used to reduce the internal resistance during the overall welding, thereby further improving the welding effect. The connection between the sub-welding part 20 and the mother welding part 10 is integrally formed with a reinforcement part 21. The outer wall of the reinforcement part 21 has an arc-shaped connection surface 22. The upper and lower ends of the connection surface 22 respectively connect the mother welding part 10 and the sub-welding part 20. The reinforcing portion 21 is used to strengthen the structural strength of the connection between the mother welding portion 10 and the sub-welding portion 20 to prevent the root of the sub-welding portion 20 from breaking during use; the arc-shaped connecting surface 22 is used to further improve the appearance integrity of the connection between the mother welding portion 10 and the sub-welding portion 20.

[0028] The welding head 30 extends downward from the lower end surface of the sub-welding portion 20 as a whole, and a plurality of welding heads 30 arranged at intervals are provided at the lower end of each sub-welding portion 30. In this embodiment, the welding heads 30 are arranged at intervals along the extension direction of the lower end surface of the sub-welding portion 20, and the welding heads 30 are arranged in multiple rows horizontally; so that the arrangement direction of the welding heads 30 is also an arc-shaped setting that fits the shape of the product, further ensuring the fit between the welding position and the product, and the welding effect is also better; the welding heads 30 in the two adjacent rows are staggered in front and back, so that the distribution position of the welding heads 30 is more uniform, further ensuring the welding effect. The diameter of the welding head 30 gradually decreases from top to bottom, so that the diameter of the connection between the welding head 30 and the sub-welding portion 20 is larger, thereby making the structural strength higher. At the same time, the smaller diameter at the bottom can make the distance between the two adjacent welding heads 30 larger, making it more convenient to dissipate heat after welding the welding heads 30 and avoiding heat accumulation between the welding heads 30.

[0029] The design focus of the present invention is that two sub-welds are integrally formed downward on the left and right sides of the mother weld, and the sub-welds are arranged left and right. Compared with the existing bolt fixing method, the one-piece forming method has better integrity and higher overall structural strength; and each sub-weld is configured to fit the arc shape of the product, and a clearance groove that fits the product is formed between the two sub-welds, so that the product can be given a position through the clearance groove during welding, thereby realizing welding on both sides of the product at the same time. At the same time, the arc shape can make the welding position of the sub-weld better fit the product, and the welding effect is also better.

[0030] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
