Self-adaptive V type support device

Abstract

The invention discloses a self-adaptive V type support device comprising a V type support block (1), a fixture body (2), support springs (3) and a screw (4); the support springs (3) are arranged in steeped holes of the fixture body (2), and the bottom of the V type support block (1) is spherical, and arranged in a mating spherical surface corresponding to the upper surface of the fixture body (2);the screw (4) penetrates the lower part of the fixture body (2), and is fixedly connected to the V type support block (1) through the support springs (3); and the upper ends of the support springs (3) come into contact with the bottom of the V type support block (1). The self-adaptive V type support device is simple and reliable in structure; the self-adaptive regulation of the V type support block in the horizontal, vertical and rotation directions of the support arc of a part can be achieved, and the optimal fit effect with the support position of the part is ensured.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to an adaptive V-shaped support device. Background technique [0002] When designing the fixture, when the supporting part of the part is a circular arc structure, the V-shaped support is often used as the positioning support element. When the same part has multiple arc structures that need to be supported, the conventional fixed V-shaped support structure can only obtain better support when the centers of the two V-shaped supports are on the same straight line or the center lines of the two V-shaped supports are perpendicular to each other. Effect. When the centerlines of the two V-shaped supports do not satisfy the above two relationships or if you want to add another V-shaped support in addition to the above two situations, over-positioning will occur, causing the parts and the V-shaped support to not cooperate normally. [0003] Such as figure 1 S...

AI Technical Summary

Problems solved by technology

There is no problem when using a conventional fixed V-shaped support structure to support cylinders A and B. However, if a fixed V-shaped support is used for cylinder C, due to the position error and angle error of cylinder C relative to cylinder A and cylinder B, and the The existence of the shape error of C itself will cause the cylinder C and the V-shaped support to be unable to support and cooperate

In actual production, the support of cylinder C can only be changed to point support, and the reliability is poor
