Detailed description of the invention
A kind of thin-wall barrel welding positioner, it comprises location bent plate 1, pivoted arm flange 4 and driver plate 2, pivoted arm flange 4 is positioned at outside the bent plate 1 of location, pivoted arm flange 4 is fixed on the bent plate 1 of location by locking stud 6, driver plate 2 is enclosed within pivoted arm flange 4, locking nut 3 is provided with between driver plate 2 and pivoted arm flange 4, driver plate 2 is provided with the gathering sill 8 corresponding with locating bent plate 1, pivoted arm flange 4 is provided with mounting hole 10 in gathering sill 8 corresponding position, be provided with guide finger 5 in gathering sill 8, guide finger 5 is connected with location bent plate 1 through the mounting hole 10 on pivoted arm flange 4.
As shown in Figure 1, pivoted arm flange 4 connects four pieces of location bent plates 1 by locking stud 6, the spacing 0 < d < 20mm of adjacent two pieces of location bent plates 1, driver plate 2 is enclosed within pivoted arm flange 4, driver plate 2 is provided with and the gathering sill 8 of locating bent plate 1 and being associated, arm flange is provided with mounting hole 10 in gathering sill 8 corresponding position, is provided with guide finger 5 in gathering sill 8, and guide finger 5 is connected with location bent plate 1 through the mounting hole 10 on pivoted arm flange 4.
As shown in Figure 6, Figure 7, the radius R of described gathering sill 8 is calculated by the move distance L of guide finger 5 and the movement angle θ of driver plate 2 and forms, and its computational methods are: R=f(L, θ), wherein Dn≤L≤D1,0≤θ≤A, 0 ° of < A < 90 °; Utilizing method shown in Fig. 7 can measure the some value Dis of R at different angles θ, the centrode of gathering sill 8 can be designed by carrying out curve fitting to the some points of Di.
