Moreover, good foundation is laid for the subsequent machining, so that the subsequent grinding and assembling workload of the personnel is greatly relieved, and the labor intensity of the construction personnel is relieved.

Description

EMU headwall assembly welding frock
Technical field
The utility model relates to a kind of EMU headwall assembly welding frock.
Background technology
The EMU headwall is as the critical component of EMUs, the parts fitted position requires very highly on the headwall, and the welder adopts after the manual line method of assembly welding to carry out the headwall assembly welding more, and this method efficient is low, effort, and do not guarantee dimensional tolerance, affect the welding precision of headwall assembly welding.
Summary of the invention
In order to overcome above shortcoming, the utility model provides a kind of simple in structure, the novel EMUs headwall assembly welding frock that can effectively control weld size.
EMU headwall assembly welding frock described in the utility model, comprise mounting platform and locating piece, wherein locating piece is divided into located lateral piece and longitudinal register piece, the located lateral piece is fixed on the horizontal both sides of mounting platform, the located lateral piece of every side is divided into two groups, and the longitudinal register piece is fixed on longitudinally both sides of mounting platform; The mounting platform both lateral sides also is symmetrical arranged two groups of perpendicular type door edge column location-plates, and its plane, place is lower than plane, locating piece place.
During work, at first with the EMU headwall body element---wallboard is placed on the mounting platform, utilize respectively located lateral piece, longitudinal register piece that it is laterally reached and vertically position, another part end corner post of EMU headwall guarantees its location dimension by door edge column location-plate.After all sizings inspections are errorless, solid with manual metal-arc welding point, comprise adding the assembly welding technique beam, prevent welding deformation, unload frock after finishing and carry out assembly welding.
EMU headwall assembly welding frock described in the utility model adopts the complete positioning control of part, the installation dimension of all parts is controlled by frock, welding deformation control within the range of permission, can guarantee in the drawing requirement margin of tolerance of headwall gate size 860 ± 2mm, the windscreen mount pad is installed the eyelet size Control in the margin of tolerance, can well guarantee product quality.Lay a good foundation for subsequent fine processing simultaneously, greatly alleviated the follow-up workload of grinding dress of personnel, alleviated workmen's labour intensity.
In order to reach better effect, EMU headwall assembly welding frock described in the utility model can also adopt following measures:
1, described EMU headwall assembly welding frock also comprises a horizontal compactor that is arranged on the mounting platform both lateral sides.Laterally the effect of compactor is that the wallboard of will have good positioning compresses, thereby guarantees that it is not subjected to displacement, thus precisely laying a good foundation for next step welding.
2, described EMU headwall assembly welding frock also comprises some packaged type compactors that are arranged on the mounting platform both lateral sides.This packaged type compactor can its role is to the gusset on the wallboard is compressed along the mounting platform horizontal and vertical movement, thereby thereby guarantee that it is not subjected to displacement, thus precisely laying a good foundation for next step welding.
3, described EMU headwall assembly welding frock also comprises the slide rail that guide pillar, the support bar that is fixedly connected with guide pillar and support bar can slide thereon, and wherein cover has removable compactor on the guide pillar, and slide rail is arranged on the mounting platform.By the movement of removable compactor on guide pillar, can compress different gussets lateral attitude on to wallboard, by changing the position of slide rail, can the lengthwise position of different gussets on the wallboard be compressed.
4, the assembly welding frock of EMU headwall described in the utility model, the surface roughness of described mounting platform is 3.2.As basic side is installed, with bottom surface fine finishining, can guarantee installation accuracy.
5, the assembly welding frock of EMU headwall described in the utility model all adopts bolt to fix between described horizontal compactor, door edge column location-plate, longitudinal register piece and located lateral piece and the mounting platform, and is adjustable.Can satisfy like this installation requirement of various vehicle headwalls.
Description of drawings
Fig. 1 is the utility model front view.
Fig. 2 is the top view of Fig. 1.
Each piece number explanation among the figure:
The 1-wallboard; The 2-end corner post; The 3-mounting platform; The horizontal compactor of 4-; 5-door edge column location-plate; 6-packaged type compactor; 7-longitudinal register piece; 8-located lateral piece; The 9-guide pillar; The 10-support bar; The 11-slide rail.
The specific embodiment
In conjunction with Fig. 1 and Fig. 2, EMU headwall assembly welding frock described in the utility model is described in detail.
As depicted in figs. 1 and 2, the utility model comprises mounting platform 3, horizontal compactor 4, door edge column location-plate 5, packaged type compactor 6, longitudinal register piece 7, located lateral piece 8, guide pillar 9, support bar 10, slide rail 11.
Wherein located lateral piece 8 and door edge column location-plate 5 are fixed on mounting platform 3 both lateral sides.Located lateral piece 8 every sides are divided into two groups, near a group of outer end wallboard 1 lateral dimension are positioned, and near a group of middle part end corner post 2 lateral dimensions are positioned.Longitudinal register piece 7 is fixed on mounting platform 3 vertical both sides, and the longitudinal size of wallboard 1 is positioned.
Be provided with the door edge column location-plate 5 of perpendicular type in the both sides in the horizontal nearly centre position of mounting platform 3, its plane, place is lower than the plane at located lateral piece and longitudinal register piece place, its role is to end corner post 2 is positioned in the size on vertical.
Position by part wallboard 1 and the end corner post 2 of above each locating piece with the EMU headwall, guarantee its size and tolerance each other.
Laterally the 4 pairs of wallboard of having good positioning 1 both lateral sides of compactor compress, thereby prevent that wallboard 1 and door edge column location-plate 5 are subjected to displacement when welding, and have guaranteed the precision of welding.
Mounting platform 3 both lateral sides are provided with adjustable slide rail 11, and support bar 10 can slide at slide rail 11, and support bar 11 tops are fixedly connected with guide pillar 9, and packaged type compactor 6 is enclosed within on the guide pillar 9, thereby laterally slides along mounting platform 3 on guide pillar 9.When the parts such as reinforcement on the wallboard 1 are welded, the portable compactor 6 that can slide, thus the reinforcement of different lateral attitudes is positioned.When wallboard 1 when position components changes longitudinally, can adjust the position of slide rail 11, thereby longitudinal size is adjusted.
