Problems solved by technology

The alignment accuracy is not high in this way, and the manufacturing tolerance is usually guaranteed by the overall machining method after welding.
In this method, the mutual positions of the four pedestal seats should be positioned at the center of the frame, but when the four pedestals are assembled upside down, it is difficult for the positioning datum to coincide with the geometric center of the frame, so only the datum positioning can be changed, and the design datum and Group pair datums do not coincide
Assemble the pedestal seat in four times, resulting in large repeat positioning errors, difficulty in ensuring overall assembly dimensional accuracy, low overall machining efficiency, and high cost

Embodiment 1

[0031] figure 1 It is a side view of a bogie frame 20 having a pedestal seat 30 welded with it according to the present invention. figure 2 , image 3 , Figure 4 They are the front view, side view and top view of a bogie frame pedestal pair device 10 according to the present invention.

[0032] like figure 1 As shown, a pedestal seat 30 is welded to the underside of the bogie frame 20 . The bogie frame 20 is a welded structural member (not shown) in the shape of a "sun" shape when viewed from a top view, which includes side beams, cross beams, etc. The lower cover and the web are welded. There are four pedestal bases 30, which are welded and connected to the lower side of the "Sun"-shaped bogie frame 20 near the corners of the four corners (such as figure 2 , Figure 4 ). The pedestal seat 30 has a surface attached to the bogie frame 20 and a protruding portion extending from the surface in a direction away from the surface, and the protruding portion constitutes a ...

Embodiment 2

[0044] In addition to replacing "the height positioning devices of the pedestal seat on the left and right sides are of the same size, the size of the Y-direction horizontal positioning device and the X-direction horizontal positioning device are different" is replaced with "the height positioning device of the pedestal seat on the left and right sides is the size The dimensions are different, the Y-direction horizontal positioning device and the X-direction horizontal positioning device have the same size and size”, other conditions are the same as those in Example 1.

Abstract

The invention discloses a bogie frame pedestal seat assembling device, which is used for positioning and assembling the bogie frame, including a tooling carcass, a pedestal seat positioning device and a positioning beam device; One, the geometric center A of the projection of the figure formed by the connection lines of a plurality of pedestal seat positioning devices on the plane where the tooling carcass is located, the geometric center B of the projection of the positioning beam device on the plane where the tooling carcass is located, and The geometric centers C of the projections of the tooling carcass on the plane where the tooling carcass is located are coincident. The pairing device of the present invention can reduce repeated positioning errors and ensure overall assembling dimensional accuracy.

Description

technical field [0001] The invention relates to an integral aligning device for a bogie pedestal seat, in particular to an integral aligning device for a bogie pedestal seat in the field of welding frame bogie manufacturing. Background technique [0002] The Y25 type bogie is widely used in the manufacture of trucks as a truck truck with a welded structure frame and a first series axle box suspension. The Y25 bogie frame is composed of two side beams, one cross beam and two end beams to form a "sun"-shaped frame. The four pedestal seats are radially distributed in the center of the frame and are welded to the lower cover plate of the side beams below the frame. . The outer edges of the four pedestal seats are projected as a rectangle, and there are strict requirements on the difference in the diagonal and the verticality of the adjacent sides. The conventional pedestal pairing method includes: inverting the frame, with the side beam lower cover plate of the frame facing up...
