Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As shown in the figure, the present embodiment comprises pedestal, first locating shaft 11, second locating shaft 1, flange 5 and positioning sleeve 8, pedestal comprises one piece of base plate 12, base plate 12 upper surface is provided with one piece of backing plate 9 riser 4 parallel and vertical with base plate with two pieces, two pieces of risers 4 are respectively equipped with a locating hole 3, two locating holes 3 are coaxial, first locating shaft 11 and flange 5 are located in a locating hole respectively, the endoporus of flange 5 is screwed hole, second locating shaft 1 is located in the screwed hole of flange 5, its jackshaft section is provided with the external screw thread 6 coordinated with flange screwed hole, the sheathed positioning sleeve 8 of shaft part on second locating shaft 1 between two pieces of risers, its tail end being positioned at outside corresponding riser is adjustment shaft part 2.
In the present embodiment, backing plate 9 is located between two pieces of risers, and the bottom surface of its upper surface and to-be-welded pieces is fitted, to locate the side of to-be-welded pieces.
In the present embodiment, on the second locating shaft 1, the shaft section diameter of sheathed positioning sleeve 8 is less than the diameter being provided with externally threaded middle shaft part.
In the present embodiment, the sidewall near flange 5 side on positioning sleeve 8 is provided with circular orientation boss 7.
In the present embodiment, the first locating shaft 11 is multidiameter, and its shaft part length be located in locating hole 3 is greater than the thickness of riser, and multidiameter centre portion is provided with end face and riser lateral surface and fits and diameter is greater than the limit shaft 10 of locating hole.
In the present embodiment, the diameter that the first locating shaft 11 is positioned at the shaft part of locating hole is less than or equal to the diameter of end-face hole relative with the first locating shaft in to-be-welded pieces, and positioning sleeve 8 diameter is less than or equal to the diameter of end-face hole relative with positioning sleeve in to-be-welded pieces.
