A universal quick positioning tool for railing assembly and welding

Abstract

The invention discloses a universal type quick positioning tool for assembly and welding of rails. The tool comprises a fixed support and movable positioning frames, wherein the fixed support comprises a support body as well as an upper positioning beam and a lower positioning beam which are arranged on the support body horizontally; each movable positioning frame comprises a diagonal brace, a sliding groove formed in the upper end of the diagonal brace and used for being matched with the upper positioning beam in a sliding manner, a lateral supporting leg arranged at the lower part of the diagonal brace and a lower positioning base arranged at the lower end of the diagonal brace and used for positioning and fixing the lower end of a rail post, a horizontal positioning arm is rotationallyconnected with the upper part of the diagonal brace through a hinged shaft, an upper positioning base is arranged at the end of the horizontal positioning arm away from the hinged shaft, an open groove used for positioning the upper part of the rail post is formed in the upper positioning base, and a locking device used for fixing the rail post is arranged at the lateral part of the open groove. With the adoption of the tool, the assembly and welding efficiency of rails of a ship is enhanced and the manufacturing quality of the rails of the ship is improved.

Description

technical field [0001] The invention relates to the technical field of railing production, in particular to a universal quick positioning tool for railing assembly and welding. Background technique [0002] As a necessary configuration of ship equipment, in order to ensure the safety of the ship, it is usually necessary to install railings on both sides of the ship and at various edges, and the workload of making railings for each ship is very large. Usually, ship railings are composed of railing columns, upper handrails, middle crosspieces, and backing plates (in some cases there is no backing plate). The manufacture method of the ship railing in the prior art is as follows: [0003] First, locate the distance between the railing columns during assembly, and then place the upper handrail and the middle crosspiece between two adjacent railing columns for positioning and welding. When positioning, it is necessary to calibrate and place the column with a calibration ruler, t...
