Abstract

The invention discloses a rail passenger car bogie hoisting seat assembly tool, and relates to the technical field of rail passenger car bogie manufacturing. The rail passenger car bogie hoisting seatassembly tool comprises a base platform, two L-shaped transverse positioning plates and a longitudinal positioning block; the two L-shaped transverse positioning plates are parallel and perpendicularto the base platform, the horizontal section of each L-shaped transverse positioning plate is fixed on the base platform, and the vertical section of each L-shaped transverse positioning plate is perpendicularly and fixedly connected with the longitudinal positioning block; the longitudinal positioning block is fixed on the base platform, the distance between the two L-shaped transverse positioning plates is 0.5mm larger than the thickness of a hoisting seat plate, and when the rear end face of the hoisting seat plate is attached to the inner end face of the longitudinal positioning block, the distance between the hole center of a circular hole of the hoisting seat plate and the upper end face of the horizontal section of each L-shaped transverse positioning plate is equal to the distancebetween the hole center of the circular hole of the hoisting seat plate and the left end face of the vertical section of each L-shaped transverse positioning plate, and the distance is equal to the circular ring outer diameter of a hoisting lug plate. Stability and reliability during assembly are guaranteed, the assembly precision of each time is guaranteed, the production efficiency is improvedby 5-10 times, and the labor intensity of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of rail passenger car bogie manufacturing, in particular to a rail passenger car bogie lifting seat assembly tooling. Background technique [0002] Such as figure 1 and figure 2 As shown, the hoisting seat 1 of the railway car bogie is composed of a suspender plate 1-1 with a circular hole on the top and two ring-shaped lug plates 1-2. During the manufacturing process of the bogie, two lug plates 1-2 need to be butt-welded at the positions of the round holes on both side walls of the suspender plate 1-1, and the centers of the two lug plates 1-2 and The center of circle of the hole of the hanging seat plate 1-1 is concentric. The current pairing method is: the operator needs to hold two lug plates 1-2, and stick them on the left and right side walls of the hanger plate 1-1, and ensure that the two lug plates 1-2 After the center of the circle is concentric with the center of the circle hole of the hange...
