Description

The pneumatic rollover stand of a kind of weld jig

Technical field

The utility model belongs to auto welding jig and makes the field, is specifically related to the pneumatic rollover stand of a kind of weld jig.

Background technology

Under the car body coordinate; The solder joint of metal plate spare is the space three-dimensional distributions, but owing to adopt the artificial mode of operation of getting ready, work angle has significant limitation; A lot of solder joints can't be got to; If increase operation simply only can cause cost waste, so must rely on self overturning of metal plate spare to realize operation.In the existing weld jig, adopt rollover stand to realize the passive upset of above-mentioned metal plate spare, so that operating personnel get ready fast more; Yet existing rollover stand can only monolaterally turn over and turn 90 degrees, and still there is the limitation of certain limit in renders operation personnel's work angle, and when welding metal plate spare when bigger soldering angle demand is arranged, the rollover stand of said structure just at all can't practical requirement.

Summary of the invention

The purpose of the utility model provides the pneumatic rollover stand of a kind of weld jig simple in structure, can realize the comprehensive upset of metal plate spare, realizes getting ready for the full angle of metal plate spare to be welded thereby be convenient to operating personnel, and operating efficiency is high.

For realizing above-mentioned purpose; The utility model has adopted following technical scheme: the pneumatic rollover stand of a kind of weld jig; Comprise the stand that two working faces are oppositely arranged; Rollover stand also comprises the master and slave carriage that is used to hold in the palm support welding metal plate spare; Master and slave carriage is arranged at respectively on the two stand working faces and with its formation and is rotatably assorted, and master and slave carriage turns axis coaxle is provided with, and rollover stand also comprises and is used to drive the rotate power unit of action of master carrier; Power unit comprises that branch is in first, second piston cylinder that master carrier rotating shaft both sides and pushing direction are provided with in opposite directions, and the vertical master carrier shaft axis of the piston rod pushing direction of two-piston cylinder and its tailpiece of the piston rod all with between master carrier constitute hinged the cooperation.

The beneficial effect of the utility model is: through being oppositely arranged the piston cylinder of two direction of propulsion positioned opposite; Thereby the complementation interlock through each other guarantees that its bilateral turning over turn 90 degrees action; And then the comprehensive action of the realization metal plate spare that holds in the palm; The handled easily personnel carry out getting operation ready for the FR of welding metal plate spare; The defective that after getting ready, must take off again artificial benefit point once more of having avoided old-fashioned rollover stand to cause, thus greatly reduce labor intensity of operating personnel, and its welding efficiency is high.

The specific embodiment

The pneumatic rollover stand of a kind of weld jig; Comprise the stand 10 that two working faces are oppositely arranged; Said rollover stand also comprises the master and

slave carriage

20,30 that is used to hold in the palm support welding metal plate spare; Said master and

slave carriage

20,30 is arranged at respectively on two stands, 10 working faces and with its formation and is rotatably assorted; Master and

slave carriage

20,30 coaxial settings; Rollover stand also comprises and is used to drive the rotate power unit of action of master carrier 20, and said power unit comprises that branchs is in first,

second piston cylinder

40,50 that master carrier 20 rotating shaft both sides and pushing direction are provided with in opposite directions, vertical master carrier 20 shaft axis of the piston rod pushing direction of two-piston cylinder and its tailpiece of the piston rod all with 20 hinged cooperations of formation of master carrier.

Further, for realizing the quick respective performances of rollover stand, said piston cylinder is a cylinder; During actual the use, the selection of its standard cylinder has two bases, according to the size of metal plate spare and the cylinder diameter of weight selection cylinder, the just top lift of this mechanism; Require to select the length of cylinder according to the height of weld jig and operation height, the impulse stroke of this mechanism just, can be specifically according to producer and the client is required selects for use, just give unnecessary details no longer one by one here.

For realizing the fit structure of 10 on master carrier 20 and support; Further preferred version as the utility model: said master carrier 20 profiles are L-shaped tabular; Comprise and be used to hold in the palm the level board 21 of support welding metal plate spare and the riser 22 that is used as the powered rotation arm; Be provided with bearing portion 11 on the working face of two stands 10 respectively; Two bearings portion 11 coaxial arrangement, the rotating shaft in each bearing portion 11 to its in opposite directions direction postpone and be fixed in the riser 22 plate face places of respective brackets, vertical its shaft axis of said riser 22 plate length directions is provided with.

Further; Rollover stand comprises base 60, and stand 10 profiles are the ladder-shaped frame shape and its bottom is fixed on the base 60, and said rollover stand comprises the linking arm 70 that the rotating shaft of the vertical bearing of brachium direction portion is provided with; Linking arm 70 1 ends are horizontally hinged in 11 rotating shafts of bearing portion and the 50 cylinder body settings of affixed second piston cylinder of its other end; This moment linking arm 70 promptly and constitute between 11 rotating shafts of bearing portion and be rotatably assorted, in addition, the tailpiece of the piston rod of second piston cylinder 50 is postponed and is articulated in the plate body place, top of rotating shaft connecting portion on the riser 22; Said first piston cylinder 40 cylinder bodies and 60 hinged settings of base, its tailpiece of the piston rod is articulated in the middle section position place of linking arm 70.

Further, said base 70 profiles are rectangular tabular, affixed two carriages in the both ends of its plate length direction, and its place, both sides is provided with the limited block 80 that is used to limit the anchor clamps anglec of rotation; Said limited block 80 is four and is oppositely arranged in twos.Above-mentioned limited block 80 can be considered limit sensors; Like this; Whenever welding metal plate spare by carriage holder support and turn to and surpass 90 when spending, its metal plate spare body promptly at first touches the limited block 80 that is positioned at base 70 corresponding edge places, limited block 80 sends a signal to the rollover stand control section; This moment, metal plate spare promptly stopped to continue action, thereby reached its position limitation protection purpose.

Describe the workflow of the utility model below in conjunction with Fig. 4-5, being positioned at cylinder body with the piston rod of its piston cylinder is reset condition:
