The utility model discloses a folding paper of side door under the installation of device to the dress, improved to dress efficiency, production efficiency promotes 3 times approximately, has solved different producers and has provided the size deviation that the circular arc that the side door plant had the same and suppression of certain difference overall dimension leads to because of the suppression frock under the side door plant exists.

Description

Side door is to dress device under railway freight car

Technical Field

The utility model relates to a side door is to dress device under railway freight car belongs to railway freight car equipment technical field.

Background

Because the lower side door of the railway freight car is purchased from a plurality of manufacturers, the pressing tools of the manufacturers have certain difference (the shapes and the sizes are the same, and the pressed arcs are different), the production is carried out by adopting a line-scribing and folding mode for a long time, and the production efficiency is low. Adopt the frock to adorn the side door down among the prior art, though effectively improved and to adorning efficiency, closing device adopts the fixed point to compress tightly, can not eliminate well that the side door is folded paper and the clearance between the lower side door board down, leads to the crack great, causes the freight train to leak the material.

SUMMERY OF THE UTILITY MODEL

Not enough to among the prior art, the utility model provides a railway freight car side door is to adorning device down, the device adopt portable closing device to compress tightly in segments and fold paper, reduce the side door down fold paper and the lower side door plant between the clearance, improve to adorning efficiency, guarantee to adorning the quality.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a side door is to dress device under railway freight car, includes the workstation and installs the longitudinal rail in the workstation both sides symmetrically, installs a pair of preceding location pin and a pair of back location pin respectively at the front and back end of workstation, has erect the portal on the longitudinal rail of both sides, the gyro wheel is installed to the lower extreme of portal, and gyro wheel and longitudinal rail rolling contact, installs the lateral shifting dolly at the top of portal, has the cylinder that compresses tightly at the bottom fixed mounting of lateral shifting dolly.

Furthermore, the front positioning stop lever and the rear positioning stop lever are fixed on the workbench through bolts or bolts.

Further, an anti-derailing device is installed between the lower end of the door frame and the longitudinal guide rail.

Since the technical scheme is used, the utility model discloses an advantage has below:

1. the utility model relates to a can dismantle location pin, avoid the location pin can not be by striking deformation in the door plant mould process on, realize the door plant mould fast, fold paper size adjustment convenient accurate purpose;

2. the assembly device has simple structure, easy operation and high assembly precision, meets the requirement of the assembly size precision of the lower side door hinge, and solves the difficult problem of the assembly deviation of the hinge caused by the line tolerance of the door panels of different manufacturers;

3. the movable pressing device is used, the butt-assembling quality is effectively guaranteed, and the butt-assembling efficiency is improved;

therefore, the utility model discloses a frock is folded paper to side door under the dress, improves and to dress efficiency, and production efficiency promotes about 3 times. The problem of different manufacturers provide the lower side door panel because of the pressing frock have certain difference (the overall dimension is the same and the circular arc of suppression is different) and the size deviation that leads to is solved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the utility model provides a: referring to fig. 1 to 3, a rail wagon lower side door assembling device includes a workbench 1 and longitudinal guide rails 2 symmetrically installed at both sides of the workbench 1, a pair of front positioning stop levers 4 and a pair of rear positioning stop levers 5 are respectively installed at the front and rear ends of the workbench 1, a gantry 6 is erected on the longitudinal guide rails 2 at both sides, rollers 3 are installed at the lower end of the gantry 6, the rollers 3 are in rolling contact with the longitudinal guide rails 2, a transverse moving trolley 7 is installed at the top of the gantry 6, and a pressing cylinder 8 is fixedly installed at the bottom of the transverse moving trolley 7. Preceding location pin 4 and back location pin 5 all fix on workstation 1 through bolt or bolt 9, can dismantle preceding location pin 4 and back location pin 5 before the mould on the door plant, have avoided the location pin to go up the mould in-process at the door plant and can not be by the striking deformation, have realized that mould is quick on the door plant, the convenient accurate purpose of size adjustment of folding paper. And an derailing prevention device is arranged between the lower end of the portal frame 6 and the longitudinal guide rail 2, so that the derailing phenomenon is avoided.

The transverse moving trolley 7 is a rail electric trolley with a model of KBK, from KBK lifting equipment, inc. in Zhejiang; the derailing prevention device is a derailing prevention device of Shandong Longjiu worker Limited company with the model of LDA.

The utility model discloses a theory of operation:

firstly, dismantle preceding location pin 4, then carry downside door board to workstation 1, fold paper with the downside door and put on the downside door board, adjust back location pin 5, after satisfying the technological requirement, remove portal 6 and lateral shifting dolly 7, make and compress tightly cylinder 8 and be located the welding point directly over, open tight cylinder 8 switch, compress tightly downside door folding paper and downside door board through tight cylinder 8, until laminating each other, then spot welding, 7 to next spot welding points of portal 6 and lateral shifting dolly, repeat this step, accomplish the weldment work of lower side door folding paper. Consequently, adopt and fold paper to adorn device installation side door down, improved to adorning efficiency, production efficiency promotes 3 times approximately, has solved that different producers provide down the side door board because of there is the same circular arc of pressing of certain difference overall dimension and different size deviation that leads to of pressing frock.
