Specific embodiment
As shown in figure 1, figure 2, figure 3, figure 4 and figure 5, the invention mainly comprises fixture trolley, supporting mechanism and positioning devices three
It is most of.
Clamping fixture table car owner will by pedestal 1, Moving caster 2, plate 3, support steel wheel 4, V-type guide pad 1, locating piece 6, push away
Bar 7 forms.Plate 3 is a kind of BASE substrate, is laid on pedestal 1, and the welding fixture size that size is installed as needed is come
Selection；Pedestal 1 is composed of the square tubes soldering of 80*80, and pedestal 1 is supported by four Moving casters 2, before two Moving casters
2 be universal wheel, facilitates deflecting, behind two Moving casters 2 be directional wheel, facilitate straight trip；It is propped up there are two respectively filling the two sides of pedestal 1
Steel wheel 4 is supportted, support steel wheel 4 is provided with ball bearing, can carry biggish radial force, and can guarantee that fixture trolley normally turns
It is dynamic；Two V-type guide pads 1 and two locating pieces 6 are placed in the side with 7 relative direction of push rod, and V-type guide pad 1 is fixture
The first guiding of trolley cooperates, it is ensured that fixture trolley quickly reaches position location with the V-type guide pad 2 10 in positioning device；
Locating piece 6 is the position portion of welding fixture front, rear, left and right four direction, is matched with the flexible positioning pin 11 in positioning device
It closes, makes welding fixture registration；Push rod 7 is retractable structure, and the person of being convenient to operation pushes fixture trolley movement when lifting,
After the completion of fixture positioning, push rod 7 is withdrawn, and will not interfere with operator's piece installing pickup.
Supporting mechanism is the support mechanism of welding fixture and fixture trolley, and supporting mechanism is by four stabilizer blades, 8, two supports 9
Two groups of supporting mechanisms are formed, two supports 9 are contacted with the support steel wheel 4 of fixture trolley, make four Moving casters 2 of fixture trolley
Vacantly, it is ensured that the accurate positioning of both direction above and below welding fixture, the front end band of support 9 is gradient, to facilitate fixture trolley
Supporting mechanism can be pushed to.
Positioning device mainly by V-type guide pad 2 10, flexible positioning pin 11, telescopic cylinder 16, positioning support 12 and compresses
Cylinder 13 forms.Two V-type guide pads 2 10 are placed in the two sides of positioning device, match with two V-type guide pads 1 of fixture trolley
It closes；Flexible positioning pin 11 and locating piece 6 on telescopic cylinder 16 cooperate, and compression cylinder 13 and positioning support 12 are fixed on and determine
On the device of position, inductor one is mounted on telescopic cylinder 16, and to incude cylinder piston rod extended position, inductor two is mounted on pressure
On tight cylinder 13, to incude cylinder piston rod extended position；Two V-type guide pads 1 are contacted with two V-type guide pads 2 10
Afterwards, hand-operated valve 1 is operated, the positioning pin 11 that stretches stretches out, across positioning support 12 and the locating piece 6 of fixture trolley, positioning of stretching
Pin 11 in place after, inductor one on telescopic cylinder 16 is connected；Then the hand-operated valve 2 15 of operation control compression cylinder 13, makes to press
The tight ventilation of cylinder 13 compresses, and after the compact heap and locating piece 6 of compression cylinder 13 compress, inductor two is connected in compression cylinder 13,
Welding fixture positioning is completed；If flexible positioning pin 11 is not passed through locating piece 6, the inductor one on telescopic cylinder 16 is without letter
Number；Two no signal of inductor if the compact heap of compression cylinder 13 is not compressed with locating piece 6, in compression cylinder 13；Sense
In the condition write-in PLC control program for answering the signal of device one, inductor two to start as welding equipment, inductor one and inductor
When two any one no signals, equipment can not be acted, and ensure that can only be welded after welding fixture accurate positioning.This
Clamp positioning device can realize the accurate positionin of welding fixture front, back, left, right, up, down six direction.
In use, operator pushes the fixture trolley for being equipped with welding fixture, fixture trolley is pushed to supporting mechanism, fixture
The V-type guide pad 2 10 on one 5 alignment locating device of V-type guide pad on trolley, after two V-type guide pad contacts, manipulator
Dynamic valve 1, telescopic cylinder 16 act, and the positioning pin 11 that stretches stretches out, the locating piece 6 in positioning support 12 and fixture trolley,
Hand-operated valve 2 15 is operated again, so that compression cylinder 13 is compressed locating piece 6, welding fixture installs.Operator withdraws push rod 7, weldering
After the completion of welding fixture use, operator first operates hand-operated valve 2 15, unclamps compression cylinder 13 and compresses, then operates hand-operated valve one
14, act telescopic cylinder 16, the positioning pin 11 that stretches retracts, and operator lifts push rod 7, drags fixture trolley, makes fixture trolley
Leave supporting mechanism, fixture completion of discharge.
