The bolts can adjust the degree of compression. Furthermore, to prevent the flange component from rotating even when compressed, the positioning post and the stepped hole prevent this phenomenon. Ultimately, this fixture can fully limit the mechanical freedom of the flange component, thereby facilitating further processing of the flange component, such as drilling holes in the flange component.

[0007] As a further improvement of the present invention, the dimension of the bottom block along the axial direction of the flange component is greater than the dimension of the top bar along the axial direction of the flange component.

[0008] The beneficial effects of adopting the above technical solution are: the bottom block plays a supporting role, so the volume is relatively large. When pressing down the top bar, it is also necessary to consider exposing the surface of the flange component as much as possible to facilitate the processing of the flange component.

[0009] As a further improvement of the present invention, the middle portion of the top bar includes an arch bridge section, both ends of the arch bridge section are integrally connected with horizontal sections, bolts movably penetrate the horizontal sections, and the bolts are located on both sides of the accommodating groove.

[0010] The beneficial effect of adopting the above technical solution is that the arch bridge section can adapt to the rotating body shape of the flange component.

[0012] The beneficial effect of adopting the above technical solution is that the concave surface is in full contact with the outer circumferential surface of the flange component.

[0013] As a further improvement of the present invention, the flange component includes a circular tube portion, the outer wall of the circular tube portion is integrally provided with a flange portion protruding radially outward, a plurality of step holes penetrate the flange portion, and the outer wall vertical surface of the bottom block where the positioning column is located can achieve surface contact with the flange portion; the accommodating groove can contact the circular tube portion.

[0014] The beneficial effect of adopting the above technical solution is that the flange portion and the stepped hole are provided by the flange component itself, and the positioning column uses the stepped hole provided therewith to limit its position.

[0015] As a further improvement of the present invention, the outer diameter of the circular tube portion is equal to the width of the accommodating groove.

[0016] The beneficial effect of adopting the above technical solution is that it is easy to fit in place.

[0017] As a further improvement of the present invention, the bolts are symmetrically distributed on both sides of the accommodating groove, and the positioning columns are symmetrically distributed on both sides of the accommodating groove.

[0018] The beneficial effect of adopting the above technical solution is that it facilitates symmetrical force application.

[0019] As a further improvement of the present invention, the outer diameter of the positioning column is smaller than the width of the accommodating groove.

[0020] The beneficial effect of adopting the above technical solution is that the positioning column does not need to be too thick, and it only needs to play the role of a positioning pin.

[0021] As a further improvement of the present invention, the axial distance from one end of the circular tube portion to the flange portion is greater than the horizontal distance from the top bar to the positioning column.

[0022] The beneficial effect of adopting the above technical solution is that the top bar can press one end of the flange component.

[0023] As a further improvement of the present invention, the end of the positioning column is chamfered.

[0024] The beneficial effect of adopting the above technical solution is that the chamfer facilitates smooth assembly of the positioning column and the step hole. BRIEF DESCRIPTION OF THE DRAWINGS
