Abstract

The invention relates to a railway wagon flat wagon middle cross beam assembling and positioning device. The device is characterized by comprising a machine frame, a longitudinal adjusting device, a positioning device, a web clamping device and a lower cover plate adjusting device, wherein the machine frame comprises a bracket, a platform and a convex baffle; the longitudinal adjusting device comprises a fixing base with an opening, a longitudinal adjusting screw sleeve and a longitudinal adjusting screw rod; the positioning device comprises three pairs of groove steels,wherein three pairs of groove steels are arranged on a front part, a middle part, a back part of the top surface of the platform; the height of the three pairs of groove steels is increased sequentially; a cross beam used for reinforcement is arranged between each pair of groove steels on the middle part and the back part; step-shaped openings are formed in the top parts of the two groove steels on the middle part; the web clamping device comprises two bi-directional air cylinders, four connecting rods, four swing rods, four pressing blocks and four supporting bases; the lower cover plate adjusting device comprises two supporting arms which extend out in the shape of U; one extending arm is provided with a positioning opening; and a cross screw-adjusting sleeve and a cross screw-adjusting rod are arranged on the top part of the other extending arm. The device can be widely applied to the assembly and the positioning of various models of middle cross beams of railway wagons.

Description

technical field [0001] The invention relates to an assembly and positioning device, in particular to an assembly and positioning device for the central beam of a railway freight car flat car. Background technique [0002] The central beam composition is the main component of the railway wagon chassis. The central crossbeam is usually a box-shaped structure, which is a connecting piece connecting the middle beam and side beams in the chassis composition. It not only plays the role of connection, but also plays the role of bearing and transmitting force. The central crossbeam of the railway freight car flat car is generally an I-shaped structure, and its assembly and positioning are relatively convenient, while the heavy-duty railway freight car has a relatively high force requirement, a more complicated structure, and a box-shaped structure, and its assembly and positioning is more difficult. There is no corresponding device to determine the position of the central crossbeam...
