Description

FIELD OF INVENTION

The present utility model relates to a base in a frame assembly tooling used for frame structures.

DESCRIPTION OF THE RELATED ART

Nowadays, when welding and assembling bogie frameworks, a new set of tooling needs to be manufactured for each type of rail car due to different widths of the frameworks, resulting in wasting human and material resources, increasing costs for manufacturing and welding the frameworks, and raising technical requirements for workers, which means that the workers have to be familiar with all of various tooling. In addition, using of welding structures in all tooling also increase difficulties of tooling storage and management.

SUMMARY OF INVENTION

One object of the present utility model is to provide a detachable universal base for a frame assembly tooling to enhance versatility of tooling for welding and assembling bogie frameworks, save costs, and reduce workloads for designing tooling and difficulty of tooling management.

In order to achieve the above object, the present utility model provides a frame assembly base for frame structures characterized in that, a longitudinal beam and a transverse beam, the transverse beam and an intermediate beam, the intermediate beam and a transverse reinforcing beam, and the longitudinal beam and the transverse reinforcing beam are all connected by bolts, and connecting blocks are provided at connections between the longitudinal beam and the transverse beam and between the longitudinal beam and the transverse reinforcing beam.

In the present utility model, all of connections in the frame assembly base are bolt connections, and connecting blocks are provided at the connections between the longitudinal beam and the transverse beam and between the longitudinal beam and the transverse reinforcing beam, so that frame widths can be adjusted to be adapted to assembling of frames having different widths by adjusting widths of the connecting blocks, thereby reducing manufacturing costs of tooling and facilitating tooling storage and management.
