Detailed Description
The utility model is further described below with reference to the accompanying drawings: as shown in fig. 1 to 3 in the attached drawings of the specification, a full-automatic pipeline welding track accurate positioning device comprises a base 1, wherein a clamping seat 2 is arranged on the base 1, a notch 3 is formed between the base 1 and the clamping seat 2, an arc-shaped cut is formed between the base 1 and the notch 3, a support 4 and a left side collision frame 5 are arranged on the base 1, a clamping wheel 6 is rotatably connected onto the support 4, the clamping wheel 6 is oval, a right side collision frame 7 is sleeved in the base 1, the right side collision frame 7 can move back and forth relative to the base 1 through a driving mechanism, and the other end of the driving mechanism extends out of the outer side of the base 1 and is fixedly connected with a hand wheel 8.
Further, the ratio between the long axis and the short axis of the clamping wheel 6 is larger than 2.
Further, the support 4 is concave, the clamping wheel 6 is rotatably connected in a groove of the support 4 through a rotating shaft, one end of the rotating shaft extends out of the support 4 and is fixedly connected with a rotating seat 9, and the rotating seat 9 is detachably connected with a rotating wrench 10.
Further, the driving mechanism is a screw.
