Description

Technical Field

[0001] The utility model relates to the technical field of valve processing, and more specifically, to a friction welding machine tool for valve body processing. Background Technique

[0002] During the valve body processing, a friction welding machine tool is required to weld and combine two single valve body parts into an integral structure.

[0003] For example, Chinese Patent CN218855868U proposes a friction welding device for mechanical processing, which discloses welding by generating heat through rotational friction between workpieces. However, such a device can only perform rotational friction welding and has poor functionality.

[0004] During the valve body processing, after two single valve body parts are welded and combined into an integral structure, a circular weld bead bulge will form at the butt joint part, and then the bulge part needs to be cut. In the prior art, the valve body after being welded by a friction welding machine tool needs to be transferred to a cutting machine tool for processing. The secondary transfer processing is not only troublesome in operation, but also time-consuming and laborious, with high costs. Therefore, how to design a friction welding machine tool for valve body processing with the function of treating weld bead bulges is a technical problem that needs to be solved currently.

[0008] Furthermore, the positioning part includes a horizontal slide bar, a horizontal adjusting screw, a horizontal swing arm, a moving seat, a vertical slide bar, a vertical adjusting screw, a vertical swing arm and a fixing seat; the horizontal slide bar and the horizontal adjusting screw are arranged on the mounting seat and their inner ends are commonly connected to the moving seat, the outer end of the horizontal adjusting screw is connected to the horizontal swing arm so that operating the horizontal swing arm makes the moving seat move horizontally, the moving seat is provided with a vertical slide bar and a vertical adjusting screw, and the bottom ends of the vertical slide bar and the vertical adjusting screw are commonly connected to the fixing seat, the top end of the vertical adjusting screw is connected to the vertical swing arm so that operating the vertical swing arm makes the fixing seat move vertically, and the tool part is mounted on the fixing seat.

[0009] Furthermore, the tool part includes a tool holder, a tool body and a fixing bolt; the tool holder is arranged on the fixing seat, and the tool body is connected to the tool holder through the fixing bolt.

[0010] Furthermore, a jack is provided at the bottom of the tool holder, and a fixing hole communicating with the jack is provided at the side of the tool holder. A tool body adapted to its size is inserted into the jack. The bottom of the tool body extends outside the jack, and a docking hole coaxial with the jack is provided on the tool body. A fixing bolt is inserted into the docking hole and the fixing hole to fix the tool body on the tool holder.

[0011] Furthermore, it further includes a protection part, which includes a back plate and a door body; the back plate is arranged on the seat body and is between the back of the fixing part and the feeding part, and the door body is arranged on the seat body and is between the front of the fixing part and the feeding part. A closed structure is formed around between the back plate and the door body and the fixing part and the feeding part, thereby reducing the problem of spark splashing during welding and the treatment of the raised part of the weld seam.

[0012] Furthermore, the door body is a transparent door for the user to observe the operation process.

[0013] Furthermore, it further includes a debris box, which is placed on the seat body and is below the tool part. The top of the debris box is open, and a handle convenient for the user to operate is installed on it.
