Specific implementation mode
In the utility model preferred embodiment, a kind of high accuracy positioning welding turntable, including turntable 1, bottom branch are provided
Support, switching platform 2, zero position platform 3 and robot control unit, which is characterized in that the bottom support is divided into turntable peace
Fill seat 4, turntable motor 5 and central frame 6 and fixture always support 7；The switching platform 2 is circumferentially spaced 90 degree around turntable motor
It arranges and is equipped with fixture mounting base；The fixture mounting base uses multigroup " idler wheel+fixed frame " structure, Z-direction bullet bolt 8 to use
Idler wheel bolt, R use 10 structure of idler wheel to being oriented to 9；The zero position platform 3 controls turntable using mechanical zero alignment
Running accuracy.
Referring to Fig. 1, switching platform 2 is circumferentially spaced 90 ° of arrangements, what centre was exposed is motor, to drive switching platform 2
Rotation.
Referring to Fig. 2, bottom support can be divided into 3 layers：1st layer is turntable mounting base 4, around circumferentially outside spacers
90 ° arrangement be useful on platform 3 calibration, vertically disposed zero-bit bolt；2nd layer is turntable motor 5, with control unit it
Between interaction, pass through robot control turntable rotation angle；Third layer is 6 He of central frame for placing and fixing switching platform
Fixture always support 7, wherein central frame 6 is square frame, is fixed on the center of fixture always support 7；Always support 7 is as its name suggests for folder support
For carrying the structure of switching platform ABCD and corresponding fixture, fixture always supports 7 and is evenly divided into 4 orientation by central frame 6,
Framework connecting piece 11 is for connecting zero position platform 3 and turntable 1.
Referring to Fig. 3, switching platform includes fixture mounting base, floating guiding mounting base（See Fig. 7）And it is arranged in two
Matching component in a mounting base.Specifically, R is mounted in floating guiding mounting base both sides to being oriented to 9；Z-direction is oriented to then in fixture
It is positioned opposite on the inside of mounting base；R is always supportted to bullet bolt mounted in fixture, not switching platform；Z-direction bullet bolt and fixed rolling
Wheel is all disposed within switching platform.Under normal station, switching platform is placed exactly in right over zero position platform, the two position pair
It answers.Four side surfaces of central frame are respectively arranged one group of R to bullet bolt, and when switching fixture, R withstands fixture to bullet bolt
So that it is pulled trolley along R towards the increased direction of turntable radius and is caught on the position of fixture to being moved to, pull trolley be for
The device of fixture is transported, switching platform is additionally provided with R to expanding pulley 12, fixed frame 13, cover board 14 and limited roller 15.
Referring to Fig. 4, showing the position relationship of zero position platform 3 and switching platform 2 after zero position, alignment is completed
Afterwards, zero-bit bolt 16 is inserted in zero position slot 17, is additionally provided with support wheel 18, wedge shaped support block 19, roller mount 20, cylinder 21.
