Description

Technical Field

[0001] The utility model relates to the technical field of improvement design of grinding devices for welding heads, and particularly relates to a grinding and repairing device for aluminum alloy friction stir welding heads. Background Technique

[0002] In friction stir welding, the design of the stirring head is very crucial. Its size and shape determine the modes of heating, plastic flow, and upsetting of the plasticized material, and also determine the size of the weld, the welding speed, and the strength of the tool. The material of the stirring head determines the friction heat generation rate, the strength of the stirring pin, and the welding temperature, and the welding temperature ultimately determines which materials can be used for friction stir welding. The material of the stirring head, the shape of the shoulder of the stirring head, and the shape of the stirring pin are the three main decisive factors for the quality of the stirring head, which are related to the performance of the connection joint, production cost, and efficiency.

[0003] After the welding head is used for friction stir welding of aluminum alloy plates or shell parts, it will adhere to some aluminum alloy materials to be welded, forming burrs and other attachments. There are also cases where oxides appear on the surface after being placed for a period of time, which may affect the quality of the next welding. The common methods for grinding the welding head mainly include two types: one is to use sandpaper to grind off the oxides on the welding head; the other is to use a chamfering tool to grind the welding head into a tapered shape (chamfer). The welding heads ground by these two processing methods are prone to generating burrs, and the grinding efficiency is relatively low. Directly putting them into use is likely to cause tip discharge of the welding head, resulting in explosion welding and affecting the welding quality.

[0004] For example, the utility model with the publication number CN219598962U discloses a grinding and repairing device for aluminum alloy friction stir welding heads, which includes a first main shaft connected to a first grinding rod, and the first grinding rod is suspended above a first rotary clamping cylinder; a second main shaft connected to a second grinding rod, and the second grinding rod is suspended above a second rotary clamping cylinder; a feeding plate with several welding heads to be ground and processed inserted thereon; a positioning mechanism including two relatively arranged first limiting plates that can be telescopically moved left and right and two relatively arranged second limiting plates that can be telescopically moved forward and backward. A support plate is provided in the cavity formed between the first limiting plate and the second limiting plate. The support plate is provided with holes and the welding head to be processed is placed thereon movably; a finished product box including a placement plate, and the placement plate is suspended above an oil tank through a frame. Lifting cylinders are provided on both sides of the oil tank, and when the oil tank is lifted, it can soak the welding heads inserted on the placement plate. This device grinds the welding heads sequentially through two grinding rods, improving the working efficiency.

[0005] In the above technical solution, although the function of grinding the welding head can be achieved, after the grinding of the welding head is completed, directly immersing the welding head in anti-rust oil or other protective oils cannot play a role in maintaining the welding head, because waste chips will be generated during the grinding process, and some waste chips will adhere to the surface of the welding head. Directly soaking in oil will cause the waste chips to adhere more firmly, thus affecting the later use of the welding head.

[0006] For this reason, a grinding and repair device for an aluminum alloy friction stir welding head is proposed. Utility Model Content
