Alignment apparatus of disc-shaped forging circle center

Abstract

An alignment apparatus of a disc-shaped forging circle center comprises calipers, a drop hammer, a suspension wire and an adjusting pulling ring. Tail ends of two caliper arms of the calipers are mutually and movably riveted and lengths of the two caliper arms of the calipers are the same. A movable riveting position of the calipers is provided with a suspension wire hole. The suspension wire hole passes through the movable riveting position of the calipers so that the suspension wire passes through the suspension wire hole and then a suspension position of the suspension wire is restrained at the movable riveting position of the calipers. One end of the suspension wire is fixedly connected to the drop hammer and the other end of the suspension wire is winded and connected to the adjusting pulling ring so that a height of the drop hammer is adjusted through pulling through the adjusting pulling ring. In the invention, a geometric property that a middle line of a bottom edge of an isosceles triangle formed by the calipers and a height on the bottom edge are superposed is used so that the apparatus with the simple structure is provided so as to accurately align the disc-shaped forging circle center.

Description

technical field [0001] The invention relates to the technical field of positioning devices for workpieces, in particular to a center-aligning device for disc-shaped forgings. Background technique [0002] In the current free forging industry, when punching the center of a disc-shaped forging, it is generally used to align the center of the circle by visual inspection and experience. However, people's vision and concentration will be adversely affected in a high-temperature working environment, especially in When processing a forging with a large outer circle, it is more difficult to find the center of the forging, so the eccentric punching of the forging often occurs, resulting in unqualified products processed later. Contents of the invention [0003] In view of this, it is necessary to provide an aligning device capable of accurately aligning the center of a disc-shaped forging. [0004] A device for aligning the center of a disc-shaped forging, including a caliper, a h...
