Alignment assistor for connecting piece with elliptical holes

Abstract

The invention relates to an alignment assistor for a connecting piece with elliptical holes, and discloses the assistor which adapts to the elliptical holes with different sizes and shapes through a shear fork structure to perform auxiliary alignment work and can be repeatedly used. The alignment assistor is characterized in that two fixed seats are arranged at the end part of a main supporting rod, and a reinforcing rod is arranged between the two fixed seats; one ends of telescopic cylinder are fixedly connected with the fixed seats, one ends of telescopic rods are sleeved with the other ends of the telescopic cylinders, telescopic springs are arranged in the telescopic cylinders, one ends of the telescopic springs are connected with one ends of the telescopic rods, the other ends of thetelescopic springs are connected with the inner walls of the telescopic cylinders, and spherical casters are arranged at the other ends of the telescopic rods. the spherical casters are made of rubber materials, nitriding treatment is conducted on the surfaces of the telescopic rods, the other ends of the telescopic rods are sleeved with the fixing sleeves, the main supporting rod is hinged to the fixing sleeves of the telescopic rods, auxiliary supporting rods are hinged to the fixing sleeves, and the main supporting rod and the auxiliary supporting rods form the shear fork structure.

Description

technical field [0001] The invention relates to an alignment aid for a connecting piece with an elliptical hole, which relates to an auxiliary device for aligning a connecting piece with an elliptical hole, and belongs to the field of mechanical processing. In particular, it relates to an auxiliary device which can be used reciprocatingly through the scissors structure to adapt to oval holes of different sizes and shapes for auxiliary alignment work. Background technique [0002] At present, when aligning double elliptical holes for some connectors with elliptical holes, it is often necessary to additionally process an elliptical pin that fits the size of the elliptical hole to assist in the alignment, and after the alignment work is completed , due to the special structure of the elliptical pin, it cannot be transferred to other holes, and then it is discarded, which is wasteful.

[0002] At present, when aligning double elliptical holes for some connectors with elliptical holes, it is often necessary to additionally process an elliptical pin that fits the size of the elliptical hole to assist in the alignment, and after the alignment work is completed , due to the special structure of the elliptical pin, it cannot be transferred to other holes, and then it is discarded, which is wasteful. At the same time, it is necessary to process a specific elliptical pin each time for the alignment of different elliptical holes , each elliptical column pin cannot be reused after being used once, which leads to serious material waste and also increases additional process flow, which affects the normal production and installation efficiency, and the existing auxiliary tools for hole alignment, its Most of them are aimed at circular holes, but cannot effectively guide and align oval holes of different sizes
