Abstract
The utility model discloses a kind of double-layer door mount structure.The frame outdoors that described double-layer door mount structure comprises closed integral door inside casing and is fixedly connected on an inside casing outer wall, described frame is outdoors spliced to form closing structure by multistage.The interior doorframe that the overall punching press of the double-deck doorframe of the utility model is formed reduces an angle place stress concentration phenomenon to a certain extent, simultaneously for driver's indoor equipment provides mounting platform, thereby enhances the overall construction intensity of doorframe, improves product quality.
Description
Technical field
The utility model relates to door field, is specially a kind of double-layer door mount structure, is particularly useful in track traffic driver door structure.
Background technology
The single frame structure that existing stainless steel drivers' cab doorframe is made up of straight flange section bar and rounded section substantially, straight flange section bar is spliced by rounded section successively or welds together.The welding capacity that the sash structure that this mode is formed needs is comparatively large, easily causes with outer skin binding face flatness poor, simultaneously because door angle is in welding region mostly, easily causes stress to be concentrated.
Utility model content
The utility model aims to provide a kind of double-layer door mount structure, and the interior doorframe that the overall punching press of this double-deck doorframe is formed can reduce an angle place stress concentration phenomenon, to a certain extent simultaneously for driver's indoor equipment provides mounting platform.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of double-layer door mount structure, its design feature is, the frame outdoors comprising closed integral door inside casing and be fixedly connected on an inside casing outer wall, and described frame is outdoors spliced to form closing structure by multistage.
Thus, closed integral door inside casing avoids the stress concentration phenomenon that welding produces, and thereby enhances the overall construction intensity of doorframe, improves product quality.
Be below the technical scheme of further improvement of the utility model:
As a kind of concrete form of structure, described frame outdoors comprise be fixedly connected with the outside wall surface of frame bottom in door threshold, be fixedly connected with door inside casing front side wall before door pillar, the rear door pillar be fixedly connected with door inside casing rear wall, and the door top rail be fixedly connected with the outside wall surface of arch in door; Described threshold, front door pillar, door top rail and rear door pillar are spliced to form closing structure successively.
Preferably, described double-deck doorframe is the double-deck doorframe of drivers' cab, and described rear door pillar is stepped, and this is stepped provides transitional region for drivers' cab and side wall.
Described front door pillar is bending part, can ensure the flatness of covering external surface thus when installing covering.
Conveniently interior doorframe and exterior door frame is fixing, described door inside casing outside wall surface has the preformed hole for being fixedly linked with frame outdoors.
More preferably, the corner of described door inside casing is arc transition structure, and can eliminate stress concentration phenomenon thus further.
Above structure, in the exterior door frame that double-layer door mount structure of the present utility model is formed by closure profile and bending part welding and overall punching press are formed, doorframe two parts form, and are connected between interior housing by the preformed hole plug welding on interior doorframe.Rear door pillar stairstepping in exterior door frame composition is that drivers' cab is transitioned into vehicle body side wall and provides transitional region.The utility model uses the big cross section closure profile of high strength and bending part composition exterior door frame structure to ensure the bulk strength of structure, and then ensures the integral planar degree of follow-up side wall covering.
Compared with prior art, the beneficial effects of the utility model are: the utility model double-layer door mount structure structure achieves the function of structure, effectively reduce an angle stress to concentrate, reduce matching requirements, improve product quality, the efficiency of production and the utilization rate of equipment.
Below in conjunction with drawings and Examples, the utility model is further elaborated.

Fig. 2 is the explosive decomposition figure of Fig. 1;
Fig. 3 is door inner frame structure schematic diagram described in the utility model.
In the drawings
Door pillar after 1-; 2-door top rail; Door pillar before 3-; Doorframe in 4-; 5-threshold; 6-preformed hole.
Detailed description of the invention
A kind of drivers' cab double-layer door mount structure, as illustrated in fig. 1 and 2, comprises exterior door frame and interior doorframe two parts, and as shown in Figure 3, door inside casing is formed in one closing structure, and its outside wall surface has multiple preformed hole 6; Exterior door frame splices assembly welding successively by rear door pillar 1, door top rail 2, front door pillar 3, threshold 4 and becomes closing structure, first drawing requirement position is adjusted to by rear door pillar 1, front door pillar 3, door top rail 2, threshold 5 special tooling in assembly welding process, welding after fixing, after exterior door frame assembly welding completes, interior doorframe 4 is placed in exterior door frame, in adjustment, doorframe 4 and exterior door frame and covering binding face are in same plane, and the rear door pillar stairstepping in exterior door frame is that drivers' cab is connected with vehicle body side wall and provides transitional region.Plug welding preformed hole 6 in finally utilizing on doorframe 4 carries out the connection that plug welding completes inside and outside doorframe, thus forms whole cab door mount structure.
The content that above-described embodiment is illustrated should be understood to these embodiments only for being illustrated more clearly in the utility model, and be not used in restriction scope of the present utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
