[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: an adjustable quick-change positioning device, comprising a positioning flange 1 and an adjusting positioning sleeve 2, the adjusting positioning sleeve 2 is installed in the positioning flange 1, and the positioning flange 1 and the adjusting positioning sleeve 2 are symmetrically penetrated with two fixing bolts 4, and the adjusting positioning sleeve 2 is penetrated with a positioning pin 3;

[0019] Among them, two arc-shaped positioning blocks are symmetrically integrally formed on the positioning flange 1, and the adjacent sides of the two arc-shaped positioning blocks constitute an arc positioning surface.

[0020] In the present embodiment, specifically: the arc positioning surface formed by two arc positioning blocks is convenient for receiving and adapting the installation of the positioning sleeve 2, and the outer sides of the two arc positioning blocks constitute an outer circle, and there is a large gap between the outer circle and the mounting hole on the mobile workbench of the equipment, so as to facilitate the adjustment work. At the same time, the mobile workbench of the equipment is the existing technology, and the end face of the positioning pin 3 is chamfered greatly, which is convenient for guiding during the positioning process.

[0021] In this embodiment, specifically: two arc-shaped stoppers are symmetrically formed on both sides of the adjusting and positioning sleeve 2, and the installation position of the adjusting and positioning sleeve 2 in the positioning flange 1 is limited by the two arc-shaped stoppers, and the end surface thereof bears the axial load.
