Description

Technical Field

[0001] The utility model relates to the field of auxiliary tools for welding tube bundles of air cooling equipment, in particular to a tube bundle turning device. Background Art

[0002] When producing air-cooling equipment, it is necessary to form a tube bundle with several copper tubes, and then weld a U-shaped tube at the end to make the tube bundle form a complete pipeline. When welding, since a circular welding point needs to be welded in a circle at each welding position, if the tube bundle is fixed, the staff needs to perform overhead welding, which is difficult to operate and further reduces the work efficiency. Therefore, during the welding process, it is necessary to first weld the semicircle above each welding point, and then flip the tube bundle to weld the other semicircle.

[0003] However, the existing technology uses a manual flipping method for the tube bundle, which is time-consuming and labor-intensive. In addition, since the tube bundle and the U-tube are not completely fixed during welding, it is difficult to stably fix the tube bundle during manual flipping, which affects the final welding quality. Utility Model Content

[0004] In view of the above-mentioned defects, the utility model provides a tube bundle turning device, which can stably turn the tube bundle during tube bundle welding, thereby improving welding quality and work efficiency.

[0005] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0006] A tube bundle turning device comprises a rotating motor and:

[0007] A pair of mutually parallel clamping mechanisms are arranged at one end of the rotating motor and are arranged outward in sequence along the axial direction of the rotating motor. The clamping mechanism includes a pair of relatively arranged linear mechanisms, and a soft clamping block is provided at one end of the output shaft of the linear mechanism. The clamping mechanism also includes a pair of parallel circular frames. The slider located at the top slides in the groove of the upper circular frame, and the slider located at the bottom slides in the groove of the lower circular frame. Pressure blocks are respectively fixed on both ends of the upper circular frame, and pressure blocks are also respectively fixed under both ends of the lower circular frame. Through holes are respectively opened at both ends of the pressure block, and a screw connecting the upper and lower pressure blocks is passed through the through hole, and the tail end of the screw extends downward from the through hole of the lower pressure block by a predetermined length.

[0008] Furthermore, a U-shaped frame is provided at one end of the output shaft of the rotating motor, and two linear mechanisms of a clamping mechanism are respectively provided at the outer ends of two parallel sides of the U-shaped frame.

[0009] Furthermore, a push plate is provided at one end of the output shaft of the linear mechanism, sliding blocks are respectively extended from the upper and lower end surfaces of the push plate, and a soft clamping block is provided on one side of the push plate.

[0010] Furthermore, the upper end surface of the soft clamping block and the upper end surface of the upper slider are located in the same horizontal plane, and the lower end surface of the soft clamping block and the lower end surface of the lower slider are located in the same horizontal plane.

[0011] Furthermore, a nut is mounted on the lower part of the screw.

[0012] The beneficial effects of this technical solution are:

[0013] It can clamp tube bundles of different widths and heights, and has strong versatility. After clamping, the tube bundle can be automatically flipped, which can improve work efficiency and ultimately improve welding quality. BRIEF DESCRIPTION OF THE DRAWINGS
