Abstract

The invention relates to a positioning fixture for welding a shielding ring and an insert. The positioning fixture for welding the shielding ring and the insert comprises a supporting seat with a central axis and an insert positioning seat; the positioning fixture is provided with a set datum plane which is perpendicular to the central axis; a positioning groove which is used for placing the shielding ring is formed in the supporting seat; the positioning groove is provided with a positioning groove wall and a notch; the centre circle of the cross section of the shielding ring at a set position is perpendicular to the central axis; the centre of the centre circle of the cross section is positioned in the central axis; a set distance is reserved between the centre circle of the cross section and the datum plane; more than two pressing plate components are uniformly distributed in the circumferential direction around the central axis of the supporting seat at intervals; each pressing plate component comprises a pressing plate, a compressing mechanism and a stop positioning piece; a contact position between the shielding ring and each pressing plate is taken as a supporting point; anda reverse torque is respectively applied to each pressing plate by the corresponding compressing mechanism and the corresponding stop positioning piece. The positioning precision and the positioningreliability between the shielding ring and the insert are ensured.

technical field

[0001] The invention relates to a positioning tool for welding a shielding ring and an insert. Background technique

[0002] The Chinese invention patent application document with the application publication number CN108320869A discloses a DC pot insulator. The pot insulator includes a shielding ring and an insert (that is, an insert) arranged outside the shielding ring. The shielding ring is arranged on the epoxy In the aluminum oxide composite part, it is connected with the outer flange through the insert. The axial section of the shielding ring is circular, the radial section is circular, and the center line of each circular surface of the axial section of the circular ring forms a section center circle, and the center of the section center circle is located at On the axis of the shielding ring; there are multiple inserts, arranged at intervals around the axial direction of the shielding ring, and the inserts are cylindrical, the axis of the inserts is ar...
