Description

Technical Field

[0001] The invention relates to the technical field of welding tooling, and in particular to a multi-angle rapid positioning tooling for profiles. Background Art

[0002] During the construction of a ship, profiles need to be welded to the main board of the hull to improve the structural strength of the main board. Sometimes, depending on the needs of the ship, the angle between the profile and the main board is constantly changing. In order to keep the profile and the main board stable when welding, it is necessary to weld the inclined supports on site according to the angle, and then perform the welding operation. The length of the profile is generally long, so it is necessary to weld multiple inclined supports between the profile and the main board. After the welding between the profile and the main board is completed, the inclined supports need to be cut off one by one, and the cutting position needs to be polished, which consumes a lot of man-hours and has low construction efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a multi-angle rapid positioning tool for profiles in view of the shortcomings of the prior art. The angle of the tool is pre-set according to the requirements of the welding angle, and then the profile is plugged into the positioning tool and placed on the main board as a whole. After welding is completed, it can be directly removed, which reduces the construction difficulty and construction cost and improves work efficiency.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A multi-angle rapid positioning tool for profiles includes a clamping device, the clamping device includes a left vertical plate and a right vertical plate, a left and a right backing surface for clamping the profile are arranged between the left and right vertical plates, the upper part and the bottom between the left and right backing surfaces form a long strip section, and the middle part forms an inverted trapezoidal section that is wide at the top and narrow at the bottom, the bottom of the right vertical plate is hinged with a base, a slide groove is provided at the outer edge of the right vertical plate, a connecting rod hinged with the base is arranged on the base, and a locking device is arranged at the other end of the connecting rod, and the angle between the clamping device and the base is changed by the displacement of the locking device in the slide groove, and when the angle is determined, the locking device is locked and fixed with the right vertical plate. By presetting the angle between the clamping device and the base, the profile to be welded is directly plugged into the clamping device, the base is placed on the main board, and welding can be performed after calibration with the planned welding position is completed, thereby improving construction efficiency, and the middle part of the clamping device is designed as an inverted trapezoidal section, which can be applicable to T-profiles and angle steels of various specifications, thereby expanding the scope of application.

[0006] Preferably, a handle is provided on the top of the clamping device for easy handholding. Holding the handle by hand facilitates plugging and installing the profile and the clamping device.

[0007] Preferably, the locking device comprises a locking bolt and a locking nut. The bolt is slid in the chute, and the locking nut is used to lock the position of the bolt in the chute.

[0008] Preferably, the slide groove is provided along the outer bevel and top edge of the right vertical plate. By providing the slide groove on the outer bevel and top edge, the range of the flip angle between the clamping device and the base is expanded.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The angle between the clamping device and the base can be adjusted according to construction needs. After the angle is determined, the profile and the clamping device are plugged and fixed, and the whole is placed at the welding position of the main board, so that the profile and the main board can be quickly positioned. There is no need to weld temporary inclined supports, which saves the cutting and grinding processes and reduces the labor cost. The inverted trapezoidal cross-section in the middle of the clamping device can meet the needs of clamping T-profiles and angle steels of different specifications, expanding the scope of application.
