Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below it is right
The present invention is further described.
As shown in Figures 1 to 5, the left end of a kind of large-diameter circular inside pipe wall welder, including bottom plate 1, the bottom plate 1 is set
There are two rotation mechanism for wind 2, the right ends in front and back distribution to be fixed in the lifting cylinder 3 placed vertically, the lifting cylinder 3 it is defeated
Outlet is fixed with rodless cylinder 4, and the driving end of the rodless cylinder 4 is connected with the mounting rack 5 in cantilever design, the mounting rack
It is vertically and fixedly provided with siding 6 on 5 cantilever end, it is along the circumferential direction uniformly distributed there are four Mobile base 7 on the left side of the siding 6, four
A Mobile base 7 is slidably connected along the circumference radial direction itself constituted with siding 6, and it is remote to be respectively connected with muzzle on the Mobile base 7
The outside welding gun 8 in center from siding 6.In the projection on same vertical plane, the muzzle of the welding gun 8 is beyond the outer of siding 6
Profile.
The right side of the siding 6 is equipped with support plate 9 in parallel, is fixed in the support plate 9 in horizontally disposed servo electricity
Machine 10 and guide rod 11, the drive shaft of the servo motor 10 are connected with lead screw 12, are equipped with circle on the lead screw 12 and guide rod 11
Column 13 is equipped with wedge block 14 with 7 corresponding position of Mobile base on the periphery of the cylinder 13, and the Mobile base 7 is equipped with and wedge
The link block 15 that shape block 14 is slidably matched.
On the siding 6 with the long slideway 6a passed through for wedge block 14, the Mobile base are equipped at 7 cooperation of Mobile base
7 right end is equipped with the limit convex shoulder 7a being tightly attached on siding 6.
The siding 6 is equipped with the rectangular opening 6b for being connected to long slideway 6a and passing through for cylinder 13.
The link block 15 is T-shaped, and the wedge block 14 is equipped with the sliding slot 14a cooperated with link block 15.
The motor 22 that the rotation mechanism for wind 2 is connected including roller 21, drive shaft with roller 21, the both ends of the roller 21 are equal
