Special fixture for arc-shaped plate

Abstract

The invention discloses a special fixture for an arc-shaped plate. The special fixture comprises a guide rail and a plurality of clamping mechanisms. The multiple clamping mechanisms are arranged on the guide rail, and each clamping mechanism comprises a base, two arc-shaped supporting plates and a supporting arm, wherein the bases are slidably mounted on the guide rail, every two arc-shaped supporting plates are arranged above the corresponding base, and each arc-shaped supporting plate is one fourth of a round ring. The special fixture for the arc-shaped plate has the beneficial effects thatthe arc-shaped plate is jacked up through two tight jacking devices arranged at the bottom of the arc-shaped plate, a compressing device is arranged on the inner side of the arc-shaped plate, a compressing wheel is utilized to compress the arc-shaped plate to the jacking device from the inner side, and accordingly clamping and fixing of the arc-shaped plate are achieved. A first slide groove formed in the arc-shaped plate is convenient for adjusting the positions of the tight jacking devices, and accordingly the arc-shaped plates with different outline radius sizes can be clamped conveniently. A second slide groove is convenient for adjusting the length of a supporting wheel extending into the inner sides of the arc-shaped supporting plates so as to clamp the irregular arc-shaped plates.

Description

technical field [0001] The invention relates to the field of tooling fixtures, in particular to a special fixture for arc-shaped plates. Background technique [0002] Fixtures are an indispensable auxiliary tool in the machining and assembly process, which can replace manual clamping and fixing of parts. [0003] The applicant found that there are at least the following technical problems in the prior art: common tooling fixtures are used to clamp the vertical or horizontal surface of standard workpieces, but cannot be fixed for non-standard curved surfaces. Some mechanical equipments that can be used to process arc-shaped plates, when clamping and fixing the arc-shaped plates, need to match the profiling plates according to the diameter of the arc-shaped plates, which will greatly increase the production cost, and the clamping Before, the copying plate needs to be replaced, so the clamping speed is slow. SUMMARY OF THE INVENTION [0004] The purpose of the present inven...
