Problems solved by technology

The existing alignment methods are only for regular parts. However, for shell parts with complex shapes and large structural anisotropy, alignment cannot be achieved by dividing the center or directly marking the shape of the part.
Since the part has been clamped and the positioning pin is blocked by the part, the method of aligning the positioning pin cannot be achieved.

Embodiment

[0050]The correction method provided by the present invention is specifically:

[0051] A. Fixture design, different housings, positioning pins and pressing points are all different.

[0052] a. The fixture is designed for complex shells. The shell is clamped and positioned according to a positioning surface (1) and two positioning pins (2). The position size (67, 88) between the two positioning pins is based on the distance between the positioning holes of the parts set up;

[0053] b. Select one of the two positioning pins as the main positioning pin (3), and design an alignment hole (4) on the side of the fixture body. The distance between the alignment hole and the main positioning pin (130, 10, 120) is the absolute size. Change;

[0054] c. There is a clamping rivet (5) at the bottom of the fixture, and the position and size of the rivet are matched with the hole position of the workbench base;

[0055] B. Clamping parts

[0056] A fixed base is installed on the machi...

Abstract

The invention belongs to the field of machining, and relates to an alignment clamp for a complex shell installation state and an alignment method. The alignment clamp comprises a clamp body, a boss isarranged on the clamp body, and the upper surface of the boss is a positioning surface for placing a part to be aligned; an auxiliary positioning pin and a main positioning pin which are respectivelyvertical to the positioning surface are arranged on the positioning surface in parallel; an alignment hole is formed in the side wall of the boss; the distance between the alignment hole and the mainpositioning pin is constant; a clamping blind rivet is arranged on the lower surface of the clamp body; and a pressing plate used for fixing the part to be aligned is arranged on the upper surface ofthe clamp body. By means of the alignment clamp for the complex shell installation state and the alignment method, the universality is high, the alignment speed is high, and the alignment correctnesscan be improved.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to an alignment jig and an alignment method, in particular to an alignment jig and an alignment method in a complex shell installation state. Background technique [0002] In the part alignment process, the existing part alignment method detects the part through an online measuring device, so as to obtain the zero point center. The existing alignment methods are only for regular parts. However, for shell parts with complex shapes and large structural anisotropy, alignment cannot be achieved by dividing or directly marking the shape of the parts. Since the parts have been clamped and the positioning pins are blocked by the parts, the method of aligning the positioning pins cannot achieve alignment. Contents of the invention [0003] In order to solve the above-mentioned technical problems in the background technology, the present invention provides an alignment jig and alignment...
