Technical Field
[0001] The utility model relates to the technical field of welding stirring heads, in particular to a welding stirring head. Background Art
[0002] Friction welding is a method that uses the heat generated by the mutual movement and friction of the end faces of the workpieces to make the ends reach a thermoplastic state, and then quickly forges them to complete the welding. Friction welding can easily connect the same or different materials, including metals, some metal-based composite materials, ceramics and plastics, and the welding stirring head is the welding head used for friction welding;
[0003] The existing patent with the authorization announcement number "CN212599627U" discloses a stirring head for friction stir welding. The stirring head for friction stir welding is an integrated structure with a simple and reasonable structure. Both ends of the arc-shaped groove on the shoulder surface are open, which is convenient for squeezing and discharging the material inside the arc-shaped groove during welding, reducing the probability and speed of material sticking to the shoulder of the stirring head, and effectively improving the service life of the stirring head and the quality of the welded joint;
[0004] However, there are the following deficiencies in this device:
[0005] 1. After the above device melts the material into fluid, the fluid guiding effect is poor, resulting in insufficient fluid mixing, which leads to excessive pores inside the welding material and poor welding effect;
[0006] 2. When the above device is in use, the heat dissipation area of the main body of the stirring head is small, resulting in poor heat dissipation capacity, which is prone to breakage due to high temperature, thereby reducing the service life of the device. Utility Model Content
[0007] The purpose of the utility model is to provide a welding stirring head to solve the existing problems raised in the above background technology.
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a welding stirring head, comprising a stirring head body, a connecting rod is arranged on one side of the stirring head body, a stirring welding needle is arranged in the middle of the other side of the stirring head body, three groups of guide grooves are evenly arranged on the outside of the stirring welding needle, three groups of arc-shaped grooves and three groups of arc-shaped convex rings are arranged on one side of the outside of the stirring head body, and an annular groove is arranged on the outside of the stirring head body close to the stirring welding needle, which can mix the welding fluid.
[0009] Preferably, the three groups of arc-shaped grooves and the three groups of arc-shaped convex rings are staggered and distributed on the outside of the stirring head body, so that the arc-shaped grooves and the arc-shaped convex rings can form arc-shaped concave-convex heat dissipation grooves to enhance the heat dissipation capacity of the stirring head body.
[0010] Preferably, a spiral groove is provided on the outer side of the stirring welding needle, which can perform spiral flow guidance and mixing on the fluid.
[0011] Preferably, clamping parts are provided at both ends of the connecting rod, so as to facilitate clamping and fixing the connecting rod through the clamping parts.
[0012] Compared with the prior art, the beneficial effects of the utility model are: the welding stirring head;
[0013] 1. Through the cooperation between the stirring tank and the stirring welding needle, the device can accelerate the upward guidance efficiency of the fluid at the bottom of the welding tip through the guide groove on the outside of the stirring head body during the rotating working process, so that the fluid at the bottom welding tip quickly enters the annular groove for mixing, and the fluid can be spirally stirred and fused evenly when rising, so that the welding fluid is mixed more fully, which can reduce the breakage of the welding needle during welding, reduce the internal pores of the welding workpiece, and improve the welding yield of the workpiece;
[0014] 2. Through the mutual cooperation between the stirring head body, the arc-shaped groove and the arc-shaped convex ring, the device forms an arc-shaped concave-convex heat dissipation groove through the arc-shaped groove and the arc-shaped convex ring, so that when the stirring head body rotates, the contact area between the stirring head body and the airflow can be increased, thereby enhancing the heat dissipation capacity of the stirring head body and preventing the stirring head body from breaking due to high temperature.

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.
[0020] See also Figure 1-3The utility model provides an embodiment: a welding stirring head, including a stirring head body 1, a connecting rod 2 is arranged on one side of the stirring head body 1, and clamping parts are arranged at both ends of the connecting rod 2, which are convenient for clamping and fixing the connecting rod 2 through the clamping parts, and a stirring welding needle 6 is arranged in the middle of the other side of the stirring head body 1, and three groups of guide grooves 5 are evenly opened on the outer side of the stirring welding needle 6, and a spiral groove is opened on the outer side of the stirring welding needle 6, which can perform spiral diversion and mixing of the fluid, and three groups of arc-shaped grooves 3 and three groups of arc-shaped convex rings are arranged on one side of the outer side of the stirring head body 1, and an annular groove is opened on the outer side of the stirring head body 1 close to the stirring welding needle 6, and the welding fluid can be mixed in the annular groove guided into the annular groove, thereby ensuring sufficient mixing.
[0021] Furthermore, the three groups of arcuate grooves 3 and the three groups of arcuate convex rings 4 are staggeredly distributed on the outer side of the stirring head body 1, so that the arcuate grooves 3 and the arcuate convex rings 4 can form arc concave-convex heat dissipation grooves to enhance the heat dissipation capacity of the stirring head body 1.
[0022] Working principle: The device forms arc-shaped concave-convex heat dissipation grooves through arc-shaped grooves 3 and arc-shaped convex rings 4, so that when the stirring head body 1 rotates, the contact area between the stirring head body 1 and the airflow can be increased through the arc-shaped grooves 3 and the arc-shaped convex rings 4, thereby enhancing the heat dissipation capacity of the stirring head body 1 and preventing high-temperature fracture. During the rotating working process, the device can contact the material through the stirring welding needle 6. When the stirring welding needle 6 rotates to make the material reach a certain temperature and melt to form a fluid, the guide groove 5 on the outside of the stirring head body 1 can accelerate the upward guidance efficiency of the fluid at the bottom of the welding tip, so that the fluid can be fully and evenly stirred and fused in a spiral manner when rising, thereby reducing the fracture of the welding needle during welding and reducing the internal pores of the welding workpiece, improving the heat dissipation effect of the stirring welding head, increasing the service life, and improving the welding yield rate of the workpiece.
