Embodiment 1

[0017] like figure 1 , 2 As shown, the present embodiment provides a mechanical puller tool for the free edge of the marine plate, which is used to fix the plate 5 on the tire frame, including a clamping device for clamping the plate 5, and for clamping the plate 5 The turnbuckle 3 connected to the tire frame, the clamping device includes a clamp 1 for clamping the plate 5, and a fastening bolt 2 for clamping the plate 5 and the clamp 1, the turnbuckle 3 One end is connected with the clamping device, and the other end is connected with the tire frame through a fastening bolt 4 .

[0018] The invention adopts the mechanical principle to replace the welded puller, and replaces the welded puller with mechanical clamping, which reduces the work of carbon planing, grinding, and repair welding after the puller is cut off, not only reduces the workload, but also improves production efficiency. Moreover, no welding and grinding process is required, which is beneficial to reduce the ...

Embodiment 2

[0024] like image 3 As shown, this embodiment provides a specific application method of the free-edge mechanical puller tooling for marine plates: after the flexible tire frame 6 is manufactured, the plate 5 is placed on the flexible tire frame 6 and does not fit tightly with the flexible tire frame 6 In addition, there will be upwarping deformation after welding the structure on the plate 5. If the puller is not used for tightening and fixing, the segment size does not meet the accuracy requirements after the segment manufacturing is completed. In order to meet the accuracy requirements, this tool is used to pull Tighten the plate 5 so that the plate 5 and the flexible tire frame 6 are closely attached. Firstly, insert the chuck 1 into the free edge of the plate 5, and clamp the chuck 1 and the plate 5 with the fastening bolt 2; then, insert the fastening pin 4 into the opening of the toggle plate 7 of the flexible tire frame 6, twist Tighten the turnbuckle bolts 3, and the...

Abstract

The invention relates to the field of ship manufacturing tools, in particular to a mechanical type puller tool for the free edge of a marine plate. The mechanical type puller tool is used for fixing the plate to a bed-jig and comprises a clamping device used for clamping the plate and a turn buckle used for connecting the clamping device with the bed-jig; the clamping device comprises a chuck usedfor clamping the plate and a fastening bolt used for clamping the plate and the chuck; and one end of the turn buckle is connected with the clamping device, and the other end of the turn buckle is connected with the bed-jig through a fastening inserted pin. According to the mechanical type puller tool for the free edge of the marine plate, a mechanical principle is adopted to replace a welding type puller, the mechanical clamping mode is used for replacing the welding type puller, work of carbon gouging, grinding and repairing welding after cutting-off of the puller is reduced, not only the workload is reduced, the production efficiency is improved, but also the welding grinding process is not required, and reducing of damage of the plate is facilitated; and meanwhile, the mechanical typepuller can be reused, and the mechanical type puller tool also has the large advantage in the aspect of reducing material waste.

Description

technical field [0001] The invention relates to the field of ship hull tooling, in particular to a mechanical puller tooling for the free edge of a marine plate connected to a workpiece through mechanical clamping. Background technique [0002] In the process of hull construction, in order to ensure the accuracy of segmentation and prevent deformation, it is generally necessary to make tire frames in advance according to the hull line shape. The plates are placed on the tire frames, and the plates and tire frames are tightly combined by welding pullers. After the subsection production is completed, the puller is cut off. After the puller is cut off, there will be a piece of entrapment on the upper floor. In order to remove a section of the puller left on the upper floor, a complicated process is required: the first step is to use a flame cutting torch to cut off the long part; the second step is to use The carbon planer cuts off the shorter part; the third step is to use a ...
