Description
Technical Field
The invention relates to the technical field of railway passenger car bogie manufacturing devices, in particular to a tool for welding a bogie beam, a traction pull rod seat and a motor hanging seat.
Background
As shown in fig. 1 to 3, a cross beam tube assembly 2 of a bogie of a railway passenger car in the prior art includes: the device comprises a crossbeam consisting of a crossbeam pipe 201 and two crossbeam end seats 202, two traction pull rod seat plates 203, two gearbox hanging seat plates (not shown in the figure), a motor anti-falling stop plate (not shown in the figure) and two motor hanging seat plates 204.
The two beam end mounts 202 are pentagonal plate structures having at least two parallel sides, and the two are respectively and coaxially connected to two ends of the beam tube 201.
The main structure of the traction pull rod seat plate 203 is a vertical shaft seat 20301 in the plumb direction, and a half-moon-shaped clamp which is vertically connected with the axial circumferential outer side wall of the beam tube 201 is arranged on the side of the vertical shaft seat 20301; the two tie rod seat plates 203 are parallel to each other, both of which are welded to the outer side wall of the beam tube 201 in exactly the same posture, and together constitute a tie rod seat.
A main body wall plate structure of the motor hanging seat plate 204 is provided with a horizontal large through hole 20401 along the axial direction of the beam pipe 201 and a positioning small screw hole 20402 along the axial direction of the beam pipe 201, and a half-moon-shaped hoop structure used for being vertically connected with the circumferential outer side wall of the beam pipe 201 is arranged on the side of the main body wall plate structure; two motor hanger plates 204 are parallel to each other, both of which are vertically welded to the axially outer side wall of the beam tube 201 in exactly the same posture, and together constitute a motor hanger.
The upper end surface of the main body wall plate structure of the motor hanger plate 204 is parallel to the upper end surface of the vertical shaft seat 20301 on the draw rod seat, and the draw rod seat and the motor hanger seat are respectively positioned at the same axial segment position in the axial direction of the beam tube 201, and the two are approximately bilaterally symmetrical about the axis of the beam tube 201.
Because the layout positions of the two motor hanging seat plates 204 and the two traction pull rod seat plates 203 on the cross beam pipe 201 are close, and the layout postures have relative position relation requirements and precision requirements at the same time, even if the four conventional universal fixtures in high-density compact layout are adopted for positioning, the fixtures still conflict and interfere with each other, reasonable arrangement cannot be realized, too many conventional positioning fixtures occupy and obstruct the operating space of a welding manipulator, the welding process of the welding manipulator needs to be stopped and adjusted for many times midway, and all operations cannot be finished continuously.
On the other hand, even if the positioning and welding of the four parts on the beam tube 201 are temporarily realized according to the correct positioning postures, if the positioning is realized only by the self structure of the welding position and the relative positions of the four parts and the beam tube 201 cannot be continuously maintained, the positioning postures of the four parts can be significantly changed again under the influence of subsequent welding thermal shrinkage deformation, so that not only is the positioning precision not effectively guaranteed, but also the beam tube 201 is subjected to a large traction effect, the beam tube 201 is subjected to distortion deformation, the mechanical structure strength is reduced, and the subsequent heavy remedial work is required to correct the beam tube 201, so that extra manpower and material resources are wasted, the production takt is prolonged, the production efficiency is reduced, the manufacturing cost is increased, and the economic benefit is reduced.
