Abstract
A kind of bogie curb girder one that prevents is the method for positioning seat assembly welding distortion; It is characterized in that: utilize one to be the hole and the groove of positioning seat end; Accomplish one be the positioning seat group to after; At curb girder homonymy one is that the bolt match with the aperture is placed at the position, hole of positioning seat, and is that the left and right directions of positioning seat is fixed with nut respectively one.The present invention is simple and feasible with the method for the anti-relative deformation in bolt location, has also saved the polishing work of accomplishing welding (or single-piece work) back tack-weld; This method for control port iron curb girder homonymy one be positioning seat relative size more accurately, reliable, simultaneously, prevented that effectively one is the welding deformation of positioning seat, thereby more effectively guaranteed the overall dimensions of port iron curb girder and framework.
Description
Technical field
The present invention relates to bogie curb girder one is positioning seat assembly welding Deformation Control method.
Background technology
Hong Kong subway curb girder one is that the positioning seat single-piece is a double groove, organizes the phenomenon to afterwards easy occurrence of tilting and relative position change in handling or put procedure; And one is the tapered plane place that positioning seat is positioned at the curb girder lower cover, easy deformation when welding.As only to put the welding deformation that solid lacing wire is a positioning seat, effect is not very desirable.
Summary of the invention
The purpose of this invention is to provide a kind of bogie curb girder one that prevents is the excessive method of positioning seat post welding distortion, guarantees bogie curb girder and framework postwelding size.
For realizing above-mentioned purpose; It is the method for positioning seat assembly welding distortion that the present invention provides a kind of bogie curb girder one that prevents; It is characterized in that: utilize one to be the hole and the groove of positioning seat end; Accomplish one be the positioning seat group to after, be that the position, hole of positioning seat is provided with the bolt that matches with the aperture at curb girder homonymy one, on bolt, being positioned at each one is that the both sides of positioning seat are provided with nut respectively and fix.
The present invention is simple and feasible with the method for the anti-relative deformation in bolt location, has also saved the polishing work of accomplishing welding (or single-piece work) back tack-weld; This method for control port iron curb girder homonymy one be positioning seat relative size more accurately, reliable, simultaneously, prevented that effectively one is the welding deformation of positioning seat, thereby more effectively guaranteed the overall dimensions of port iron curb girder and framework.
Description of drawings
Fig. 1 is that bogie curb girder one is the positioning seat structural representation;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
With reference to Fig. 1,2,3; Utilizing bogie curb girder 2 one is hole and the groove of the Φ 50 of positioning seat 1 end existence; Accomplish one be the positioning seat group to after, place the bolt 3 that matches with the aperture at position, positioning seat hole, on bolt, being positioned at each one is that the both sides of positioning seat are provided with nut 4 respectively and fix.
Claims (1)
1. one kind prevents that bogie curb girder one from being the method for positioning seat assembly welding distortion; It is characterized in that: utilize one to be the hole and the groove of positioning seat end; Accomplish one be the positioning seat group to after; At curb girder homonymy one is that the bolt match with the aperture is placed at the position, hole of positioning seat, and is that the left and right directions of positioning seat is fixed with nut respectively one.
