Technical field
The utility model relates to a kind of vehicle production frock, especially relates to a kind of body frame and always welds welding fixture.
Background technology
Vehicle body six large stretch of skeleton assembly weldings are be welded critical processes in producing of bus body.This operation is not only determining the hexahedral fitted position precision of bus body, and is the throat operation of restriction vehicle body soldering line productivity ratio.In order to guarantee integral body skeleton dress weldering precision, design is also made total welding welding fixture, since be subjected to various vehicle car load length, highly, wheelbase equidimension difference, design and make several assemblies welding anchor clamps respectively at different vehicle body framework constructions, and the clamp structure complexity, each anchor clamps can only satisfy several vehicles.
Production for the many kinds of small lot, this mode cost of can increasing input greatly, and the occupied ground area is many, the operation more complicated, because vehicle is changed frequent, anchor clamps are the meeting gross distortion after repeatedly lifting by crane, moving, and to need to adjust workload very big at every turn, cause production efficiency low, adverse consequences such as product quality decline always.
The utility model content
Always be exactly the purpose of this utility model provides a kind of multiple vehicle, body frame that production efficiency is high of being applicable to weld welding fixture for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of body frame always welds that welding fixture comprises movable underframe, left movable fixed mount, right movable fixed mount, fixed mount is enclosed in the left side and fixed mount is enclosed on the right side, the below of the movable fixed mount in a described left side and right movable fixed mount is provided with width adjustment mechanism, described left side is enclosed fixed mount and right side and is enclosed fixed mount and be connected on left movable fixed mount and the right movable fixed mount by elevating mechanism respectively, fixed mount is enclosed and the clamp that is equipped with on the fixed mount be used to clamping the side wall frame assembly is enclosed on the right side in the left side, and described movable underframe is arranged on that fixed mount is enclosed in the left side and enclose between the fixed mount on the right side.
Described width adjustment mechanism and elevating mechanism are connected with the hydraulic-driven assembly, drive by the hydraulic-driven assembly.
Described width adjustment mechanism is to be arranged at the roller of left movable fixed mount and right movable fixed mount bottom and to be arranged on ground guide rail.
The width setting of described guide rail movable fixed mount and right movable fixed mount along a left side.
Described elevating mechanism is the dovetail groove guide rail.
Described hydraulic-driven assembly comprises electric-controlled switch and the hydraulic cylinder of being controlled by electric-controlled switch.
Described movable underframe is that the steel plate welding processing of 15mm forms by No. 16 channel-section steels and thickness, and described guide rail is formed by No. 35 channel-section steel welding processing.
Compared with prior art, the utlity model has following advantage:
(1) scope of application is wide, and the frock adjustment is quick, be fit to length of wagon, highly, wheelbase, window be apart from all batch processes of different automobile types;
(2) safe and reliable, each parts of device are made meticulous, the accurate positioning when operation of motor bus vehicle body assembly welding anchor clamps, and anchor clamps are swift in motion effectively, reliable operation;
(3) easy to operate, the space spaciousness, the workman is easy to operate, adapts to welding requirements, convenient welding, taking out workpiece from anchor clamps should make things convenient for;
(4) production efficiency height can be according to the difference of vehicle, and the rapid adjustment anchor clamps make the body side wall flatness height of assembly welding.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As depicted in figs. 1 and 2, a kind of body frame always welds welding fixture, comprise movable underframe 1, left movable fixed mount 21, right movable fixed mount 22, fixed mount 31 is enclosed in the left side and fixed mount 32 is enclosed on the right side, the below of the movable fixed mount 21 in a left side and right movable fixed mount 22 is provided with width adjustment mechanism, this mechanism is made up of the roller 4 that movable fixed mount is set and surface-based guide rail 5, guide rail is formed by No. 35 channel-section steel welding processing, along the width setting of movable fixed mount, make it can regulate distance between left movable fixed mount 21 and the right movable fixed mount 22.
The left side is enclosed fixed mount 31 and right side and is enclosed fixed mount 32 and be connected on left movable fixed mount 21 and the right movable fixed mount 22 by elevating mechanism respectively, the left side is enclosed fixed mount 31 and right side and is enclosed and be equipped with clamp 6 on the fixed mount 32, clamp two side wall frame assemblies of vehicle body by clamp 6, concrete clamps structure as shown in Figure 3.Owing to be provided with elevating mechanism, can make the adjustable height of two side wall frame assemblies, thereby be applicable to various vehicle.This elevating mechanism has adopted dovetail groove guide rail 9, and as shown in Figure 4, the dovetail tongue is connected gusset fixed mount and movable fixed mount respectively with dovetail groove.
Elevating mechanism and width adjustment mechanism all drive by the hydraulic cylinder 8 by electric-controlled switch 7 controls, make anchor clamps reach height and the width of car body requirement.Movable underframe 1 is that the steel plate welding processing of 15mm forms by No. 16 channel-section steels and thickness, is arranged on that fixed mount 31 is enclosed in the left side and enclose between the fixed mount 32 on the right side, is used for the fixed base plate frame assembly.
