Abstract
The utility model relates to a car body sidewall welding positive group backward deformation device. Before positive group welding, the backward deformation device upward pushes against a sidewall section plate in advance; and in process of welding, backward deformation is provided so as to eliminate forward deformation, thus being capable of ensuring the profile tolerance and chordal accuracy of the sidewall after being welded. The backward deformation device is directly riveted on a sidewall positive group tooling moldboard and comprises an installation plate riveted on the sidewall positive group tooling moldboard, and a group of guide frames integrally connected with the installation plate; screw rods are vertically screwed at the centers of the guide frames in a penetrating manner; and the top ends of the screw rods are connected with guide plates by pin shafts. Before positive group welding, the car body sidewall is positioned on the sidewall positive group tooling moldboard. The screw rods are adjusted manually, and the guide plates upward pushes against the car body sidewall while the screw rods move upwards. When in positive group welding operation, the pre-formed backward deformation can offset the forward deformation formed due to welding.
Description
Technical field
The utility model is the car body side wall welding sequence that is applied to the rail vehicle production scene, and concrete is prevents and eliminate the local deformation problem that forms because of positive bond pads, belongs to mechanical manufacturing field.
Background technology
The speed per hour of present domestic EMUs has reached velocity stage more than 300 kilometers, and the high-speed cruising inevitable requirement body construction of rail vehicle has rigidity intensity and lightweight, fairshaped design performance concurrently.
The car body side wall that adopts aluminium alloy extrusions is understood in welding post formation distortion vertically downward when carrying out positive bond pads, thereby has influence on the surface smoothness of side wall integral body.The existing solution of generally taking is to remedy this defective workmanship by flame adjusting method after welding operation.
Owing to be to adopt the back to mend technology, have influence on the surface strength chord high accuracy of side wall profile inevitably.It is bigger that workload is repaiied in following thermal transfer, both had been unfavorable for reducing field operation intensity and workload, also can have influence on the production efficiency of side wall welding assembly.
The utility model content
The reversible deformation device is just being organized in car body side wall welding described in the utility model, its purpose of design is to address the above problem and adopts the reversible deformation device upwards to hold out against the side wall profile plate in advance before positive bond pads, in welding process, provide a reversal deformation amount to eliminate the forward deflection, realize a kind of adjusting mode simultaneously of welding, not only the field operation amount is few, and can guarantee to weld the surface strength chord high accuracy of back side wall profile.
For realizing above-mentioned purpose of design, described car body side wall welding is just being organized the reversible deformation device and directly is being riveted on side wall and is just organizing on the tool mold, and it mainly includes:
One is riveted on side wall is just organizing installing plate on the tool mold,
The one group of leading truck that is connected with the installing plate one,
Leading screw vertically runs through the leading truck center that is bolted in, and the top of leading screw connects guide plate by bearing pin, and,
The surface of guide plate has the profile identical with the side wall medial surface.
As above-mentioned basic scheme, before carrying out positive bond pads, the car body side wall is positioned at side wall and just organizes on the tool mold.
By the manual adjustments leading screw, when leading screw moved up, guide plate upwards held out against the car body side wall.When implementing positive bond pads operation, preformed reversal deformation can be offset the forward distortion that forms because of welding.
After finishing weld job, side wall profile tolerance and action are kept, and need not to descend thermal transfer to repair again, and operating personnel's workload is less.
In addition,, can accurately control the reversal deformation amount that guide plate upwards holds out against the car body side wall, thereby reach the action exact value of design and use parameter according to the side wall numerical value of different specification size and external form radian.
For further improving the precision of reversal deformation amount, guarantee the symmetry that guide plate moves both vertically, can take following improvement feature, be provided with one group of axis of guide in the guide plate both sides, guideway is located at the leading truck both sides.
The guide rail that the axis of guide can vertically move as guide plate cooperates guide plate to promote from bilateral symmetry ground, can prevent guide plate occur spraining strength and lateral deviation.
For controlling and regulate the active force that upwards holds out against side wall effectively, can on leading screw, be arranged with and be used to regulate the nut of pressure and retaining vertically upward.
In sum, the utility model car body side wall welding is just being organized the reversible deformation device and is being had the following advantages:
Realize a kind of frock and method of operating that the reversal deformation amount is eliminated welding forward deflection of reserving, need not the welding back down thermal transfer repair, the field operation amount is less, load and improve integral production efficient helps lightening one's labor.
Can accurately guarantee to weld the surface strength chord high accuracy of back side wall profile, help to improve the on-the-spot installation quality of side wall.
The reversible deformation device can Fast Installation, dismounting, uses simple and convenient.

Fig. 1 is the generalized section of described reversible deformation device;
Fig. 2 is the side direction generalized section of Fig. 1;
As depicted in figs. 1 and 2, leading truck 1, guide plate 2, leading screw 3, bearing pin 4, nut 5, the axis of guide 6, installing plate 10.
The specific embodiment
The reversible deformation device mainly includes, the one group of leading truck 1 that is connected with installing plate 10 one.
Leading screw 3 vertically runs through leading truck 1 center that is bolted in, and the top of leading screw 3 connects guide plates 2 by bearing pin 4, is arranged with to be used to regulate the nut 5 of pressure and retaining vertically upward on leading screw 3.
The surface of guide plate 2 has the profile identical with the side wall medial surface, is provided with one group of axis of guide 6 in guide plate 2 both sides, and the axis of guide 6 is set in leading truck 1 both sides.
