Problems solved by technology

Sometimes the parts of the driver's cab are directly welded on the platform, and after the assembly is completed, the parts and various supporting rods are cut off by flame cutting, which not only makes the production progress very slow, but also causes the surface of the parts to be damaged. Difficult to guarantee assembly quality
Moreover, the consumption of auxiliary labor and various energy and materials is very large.

Embodiment Construction

[0008] see figure 1 , The positioning column (2) in this embodiment is provided with positioning bolt holes (1) on its base. The top shaft (10) of the clamping structure is laterally protruded from the upright column (2) in a threaded manner. 7) and the pin seat (15) are provided with corresponding positioning pin holes and positioning pins (12), the hook end of the hook arm (7) is provided with a positioning bolt (8), and the positioning bolt (8) is provided with a locking nut ( 9). The sleeve seat (3) of the compression structure is fixed on the upright column (2), the short beam (5) is inserted into the sleeve seat (3), and can move laterally in the sleeve seat (3). There is a vertical threaded top shaft (4), and the upper end of the top shaft (4) is provided with a rotating handle (6).

[0009] According to the difference of the actual position, the height of the positioning column will be different, and the angle of the clamping structure and the pressing structure on ...

Abstract

The invention relates to a locomotive cab steel structure flexible assembly jig, comprising a positioning upright column (2) distributed on a platform (16), wherein the bottom seat of the upright column (2) is fixed on the platform (16), a clamp structure and a compact structure are arranged on the upright column and a head shaft (10) of the compact structure transversely penetrates out of the upright column (2); a tail end of a claps arm (7) is in a hinged connection with a pin boss (15) through a pin roll (13), wherein the claps arm (7) and the pin boss (15) are provided with a correspondingpositioning pin hole and a positioning pin (12); the claps end of the claps arm (7) is provided with a positioning bolt (8) and a locked screw nut (9); a main beam transverse (5) of the compact structure is inserted into a socket (3) and can mover horizentally in the socket (3); the end part of the main beam transverse (5) is provided with a vertical screw thread head shaft (4). The invention issuitable for various motorcycle types, can be reused, can improve assembling quality and efficiency, and is adapted to mass assembling production.

Description

technical field [0001] The invention belongs to the technical field of locomotive manufacturing, and in particular relates to a novel locomotive cab steel structure flexible assembled tire. Background technique [0002] Over the years, in the production of various traction power diesel locomotives and electric locomotives and the steel structure of the urban express rail car cab, the platform is basically used for scribing and marking, welding positioning blocks, components welding supporting rod connections, and applying welding. Support rods adjust the verticality and size of components. When assembling the parts, first weld various support rods to fix the parts, and then use a disc ruler and a wire hammer to repeatedly adjust the verticality, diagonal and related geometric dimensions of the measured parts, which requires multiple operators with certain skills. . Sometimes the parts of the driver's cab are directly welded on the platform, and after the assembly is comple...
