Description

Multifunctional codeless mounting tooling Technical field

The invention relates to a mounting tool, in particular to a multifunctional toolless mounting tool.

Background technique

Temporary installation tooling is required during the welding operation of the profile steel to prevent the profile steel from shifting during the welding of the profile steel. For example, in the process of ship construction, it is necessary to fix the position where the section steel and the motherboard are installed, and perform welding on the motherboard. There are two main methods in the current practice: 1. Using the residual material on the edge of the board, welding it into a door frame close to the welded steel, placing the bottom of the profile on the bottom of the door and welding it to the base metal, and then tightening it with an iron tip. The disadvantage of the method is that after the profile and the base metal are welded and installed firmly, the door frame needs to be removed from the motherboard. In the process of tapping the door frame, the motherboard is pulled, and the soldering code is left on the motherboard to increase The amount of work to be repaired; when the profiled steel is long, there will be more yards and feet, and the amount of repairing work is extremely large, which not only increases the work intensity, reduces the efficiency, but also greatly affects the quality and aesthetics of the ship installation and reduces the size of the ship. The owner's satisfaction with the ship. 2, using magnetic tyrants without code foot installation tooling, this type of installer is equipped with two types of hydraulic type and screw type, which is slightly better than the welding method using the door frame tool, but because the permanent magnet suction of such installation tool is small, It is only suitable for the installation of thinner profiles. It is not suitable for medium and heavy profile installation. The profile of slightly larger 300mm flat steel will not work properly. In addition, there is only a single function to press from top to bottom. When it is necessary to increase the side shift, an additional shifting tool of the same product is required, which takes a long time to control the permanent magnet switch, and the efficiency is not high. It is not easy to use, and when the position limit is encountered, the use of the magnetic weapon tool cannot be carried out.
