Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1-2, the utility model provides a single-shaft tailstock walking positioner, which comprises a base 1, a power seat 2, a walking tailstock 3 and a tailstock sliding table 4, wherein the base 1 is fixedly arranged on the bottom surface through a leveling foot, the power seat 2 is fixedly arranged on one side of the base 1, the tailstock sliding table 4 is arranged on the base 1 through a linear guide rail, the walking tailstock 3 is fixedly arranged on the tailstock sliding table 4, a tailstock walking driving mechanism 5 is arranged on the tailstock sliding table 4, a clamp driving mechanism 6 is respectively arranged on the power seat 2 and the walking tailstock 3, the clamp driving mechanism 6 drives a welding tool clamp 7 arranged on the power seat 2 and the walking tailstock 3 to move, the tailstock sliding table 4 is driven by the tail walking driving mechanism 5 to move linearly, so as to realize the position adjustment of the walking tailstock 3 fixedly arranged on the tailstock sliding table 4, the desired working position is selected.
