Problems solved by technology

Existing plane drills can only drill smaller flanges. Generally, large flanges are drilled with radial drills. Large flanges have larger diameters and more holes. Before drilling with radial drills, it is usually necessary to make samples on the flange point, so that the drill bit can find the center, and the flange of each part number is generally not interchangeable, and it usually takes a lot of time to make samples and punch points, which is time-consuming, inefficient and not accurate

Abstract

The invention provides a flange drilling indexing disc. The indexing disc comprises a base, a rotating shaft, an upper ratchet wheel, a lower ratchet wheel, a table top fixing shaft seat and a flangefixing table top, wherein the rotating shaft is arranged on the base, and the flange fixing table top is connected with the table top fixing shaft seat; a containing cavity is concavely formed in thebase, one end of the rotating shaft is connected with the base, and the other end of the rotating shaft is connected with the flange fixing table top; the upper ratchet wheel and the lower ratchet wheel are arranged in the containing cavity in a stacked mode, and the rotating shaft penetrates through the upper ratchet wheel and the lower ratchet wheel at the same time; the table top fixing shaft seat is arranged at the top of the base, and the inner side of the table top fixing shaft seat is connected with a table top rotating shaft seat through table top fixing balls; table top rotating ballsare arranged between the table top fixing shaft seat and the flange fixing table top; and two ratchet wheel clamping pins are inserted into the circumferential wall of the base, one end of each ratchet wheel clamping pin extends into the containing cavity, and the other end of each ratchet wheel clamping pin is located outside the peripheral wall of the base. The flange drilling indexing disc ishigh in precision, time-saving and labor-saving and capable of improving the drilling operation efficiency of a radial drill and the flange drilling quality at the same time.

Description

technical field [0001] The invention relates to the technical field of flange processing equipment, in particular to a flange drilling indexing plate. Background technique [0002] With the continuous development and improvement of power grid construction, the application of flanges is becoming more and more extensive, such as: flanges for connecting steel pipes in steel pipe towers, flanges for connecting main rods in steel pipe poles, and flanges for connecting steel pipes in substation structure supports. Existing plane drills can only drill smaller flanges. Generally, large flanges are drilled with radial drills. Large flanges have larger diameters and more holes. Before drilling with radial drills, it is usually necessary to make samples on the flange point, so that the drill bit can find the center, and the flanges of each part number are generally not interchangeable, and it usually takes a lot of time to make samples and punch points, which is time-consuming, ineffic...
