A kind of welding tooling for collision prevention girders

Technical field

Collision prevention girders more particularly to a kind of welding tooling for collision prevention girders the utility model is related to automobile.

Background technology

More and more with the demand of automobile, automotive light weight technology trend is more and more apparent, as user is to automotive safety system The raising of number requirement so that the quality requirement of collision prevention girders is also constantly soaring, and collision prevention girders upgrade to aluminium by traditional carbon steel material and close Golden material, and the thin aluminium alloy of thickness is easily deformed in the welding process, traditional manual assembling and the welding of non-PA/PB positions Guarantee, planarity requirements, the requirement of hole position and the requirement of weldquality of its size can not have been met.

Collision prevention girders（As shown in Figure 1, 2）, before it is by front anti-collision beam, front anti-collision beam connecting plate, left front collision prevention girders installing plate, the right side Collision prevention girders installing plate, front tow hook fixing bracket, front tow hook screwed pipe are welded to form.The assembling of each component is needed more in collision prevention girders A position and angle realize positioning and rotation and need to keep higher accuracy.And certain privileged sites in collision prevention girders, to zero The fitted position of component has degree of precision requirement, and the flatness, verticality to part also there are certain requirements.Traditional manual assembling Technique and vertical-up welding connect, horizontal position welding technique can not ensure the precision of size and the plane of part of each component assembling in collision prevention girders The requirements such as degree, verticality, the precision in hole.

Utility model content

The purpose of this utility model is that the deficiency in for the above-mentioned prior art, provides one kind, pass through, and then realize Purpose.

In order to solve the above technical problems, the utility model adopts the following technical solution：

A kind of welding tooling for collision prevention girders, it includes rollover stand and positioning compression mechanism；The rollover stand includes turning over Pivoted frame ontology, load bearing arm, driving motor, index dial and with the matched rotating latch of the index dial, the load bearing arm is with turning over Pivoted frame ontology is rotatably connected, and the driving motor is fixed on rollover stand ontology and passes through one end phase of index dial and load bearing arm Even；The positioning compression mechanism includes the stent being fixedly connected with load bearing arm, and the left and right ends of the cradle top are respectively provided with one Groove profile locating piece is equipped with the pressure arm being matched therewith and the hand for the pressure arm to be controlled to rotate on both of the aforesaid groove profile locating piece , and it is additionally provided with positioning pin on the groove profile locating piece of cradle top left end；The stent is respectively arranged on the left side and the right side One cushion block and the second cushion block, first cushion block are respectively arranged in the front and the rear with a first cylinder pressure head, second cushion block it is front and rear A second cylinder pressure head is respectively provided with, and perpendicular locating rod is additionally provided with above second cushion block.

Further, first cushion block is riveted with the second cushion block by carbon steel sheet and aluminium sheet, and the carbon Copper coin is equipped between steel plate and aluminium sheet.

Further, the thickness of the copper coin is 30mm.

The welding tooling for collision prevention girders that the utility model is proposed has the following advantages that：

1st, the precision of welded articles is improved, ensures its interchangeability.When assembling tack welding, if without using frock clamp, Even if sub-assembly is made of several parts, it is intended to ensure the accurate relative position of each part and impossible.In addition, In welding process, weldment is often deformed, especially complicated structure, and deformation reaches the journey that can not be eliminated sometimes Degree just influences whether general assembly operation below or even causes product rejection.Want collision prevention girders welding procedure ask welding after reach+- The tolerance of 0.5mm for the so big workpiece of welding capacity, can not be realized using manual assembling, welding.It is new using this practicality The welding tooling that type is proposed, when can not only ensure to assemble tack welding, each correct relative position of part, and can prevent Or reduce the welding deformation of workpiece；When especially producing in batches, welding quality can be stablized, reduce weldment dimensional discrepancy, ensured The interchangeability of product.So as to meet the quality requirement of product.

2nd, it raises labour productivity, reduces manufacture cost.Welded production process generally comprises：Prepare（Weld material Cleaning, drying, workpiece bevel of material etc.）, assembling（To just, positioning, clamp or tack welding etc.）, be turned to the weldering of suitable position It connects, clear up（The removal workpiece from frock clamp）, examine, post weld heat treatment and correction and the last processes such as examine.Before weldering and weld Afterwards the amount of labour of every aided process often beyond welding sequence in itself.Therefore, most effective measure of raising labour productivity is Reduce the time of aided process.In welded production, since the complexity of different weldments is different, pure weld interval is only The 10% ~ 30% of product whole process times is accounted for, remaining is the times such as stock, assembling and back work.It is if new using this practicality The welding tooling that type is proposed, then labor productivity can improve 40%.Obviously, the production cycle to be shortened improves labour life Yield other than using automatic Welding Process, will also use advanced assembly technology, using mechanization and high degree of automation Frock clamp.

3rd, ensure welding quality.In welding procedure, horizontal position welding, vertical position welding are all detrimental to the welding position of appearance of weld, shape Into weld defect, it is difficult to ensure weldquality.It is combined, workpiece can be turned over rotating latch and rollover stand using index dial 0 degree, 90 degree, 180 degree position are gone to, can not pass through tooling band in the welding of PA/PB positions in horizontal position so as to fulfill certain It starts building part rotation, so as to which the PA/PB positions for ensureing to be welded on most useful for forming are welded, the increase of copper billet is convenient for absorbing anticollision The heat that beam connecting plate and front anti-collision beam installing plate generate when welding, reduces the deformation of front anti-collision beam installing plate, anticollision before guarantee The precision of beam installation plate hole position.

4th, it reduces labor intensity, guarantees safe production.The welding tooling proposed using the utility model can realize work Part positioning is quick, convenient for mounting and clamping, laborsaving, effectively mitigates heavy physical labor during weldment assembling positioning and clamping so that labour Condition is greatly improved, while is conducive to the safety management of welding production.It, can be significantly particularly with the workpiece overturn It reduces labor intensity, ensure safety in production.
