Positioning tool of lateral beam of bogie

Abstract

The invention belongs to the technical field of riveting, which provides a positioning tool of a lateral beam of a bogie. The positioning tool mainly comprises a base (1), portal frames (2) and two puller bolts (3). A plurality of portal frames (2) are arranged on the base (1). Each portal frame (2) is formed by a positioning plate (4), two reversed L-shaped crank arms (5) and two lead screws, wherein one ends of the two reversed L-shaped crank arms (5) is connected to one side of the base (1), the upper end of the positioning plate (4) is connected between the two reversed L-shaped crank arms (5), the lower end of the positioning plate (4) is connected to the other side of the base (1), a lead screw I (6) is connected onto transverse arms of the reversed L-shaped crank arms (5), and a lead screw II (7) is connected onto vertical arms of the reversed L-shaped crank arms (5). The two puller bolts (3) are arranged on the base (1). The positioning tool of the lateral beam of the bogie avoids errors happening during lineation assembly, can enable a vertical plate and an upper cover plate to be accurately assembled together and enable the vertical plate and a lower cover plate to be assembled together in a high-efficient and high-quality mode, and improves production efficiency.

Description

technical field [0001] The invention belongs to the technical field of scribing and pairing by riveters, and mainly relates to a positioning tool for a side beam of a bogie, which is suitable for the secondary assembly and welding process of the side beam in the production of the bogie. Background technique [0002] The bogie side beam is composed of an upper cover plate, a lower cover plate and a plurality of vertical plates located between the upper and lower cover plates; when manufacturing the bogie side beam, the upper and lower cover plates of the bogie side beam and the vertical plate are passed through the marking assembly Assembling and welding in the right way, this traditional operation mode is not only inefficient, but also difficult to guarantee the relevant dimensions, which cannot meet the requirements of drawings and processes: the longitudinal dimension of the side beam is 3440mm, with a tolerance of ±4mm; the straightness of the lower cover plate is required...

Problems solved by technology

[0002] The bogie side beam is composed of an upper cover plate, a lower cover plate and a plurality of vertical plates located between the upper and lower cover plates; when manufacturing the bogie side beam, the upper and lower cover plates of the bogie side beam and the vertical plate are passed through the marking assembly Assembling and welding in the right way, this traditional operation mode is not only inefficient, but also difficult to guarantee the relevant dimensions, which cannot meet the requirements of drawings and processes: the longitudinal dimension of the side beam is 3440mm, with a tolerance of ±4mm; the straightness of the lower cover plate is required to be 3mm, The plane parallelism of both ends of the lower cover is 3mm

If the upper and lower cover plates and vertical plates are not accurately positioned according to the drawing requirements during assembly, it will affect the quality of the entire side beam, thereby affecting the assembly of almost all accessories on the frame, and greatly affecting the quality of the final product
