Sphere conveying mechanism of device for machining high-precision sphere

Abstract

The invention discloses a sphere conveying mechanism of a device for machining a high-precision sphere. The sphere conveying mechanism of the device for machining the high-precision sphere comprises a support, an upper free rolling way, a lower free rolling way, an outer spiral rolling way, a mandrel and scrapers, wherein the mandrel is connected with a feeding driving mechanism which is used for driving the mandrel to rotate, the scrapers are arranged on the outer circle of the mandrel at equal arc intervals, the size of a gap between every two adjacent scrapers is larger than that of the sphere to be conveyed, the outer spiral rolling way is arranged from top to bottom and is attached to the outer side faces of the scrapers, a conveyance station used for containing the sphere is formed by the gaps between the adjacent scarpers and the outer spiral rolling way, the upper free rolling way and the lower free rolling way are obliquely arranged, the upper end of the outer spiral rolling way is connected with the upper end of the upper free rolling way, the lower end of the upper free rolling way serves as an outlet of the sphere conveying mechanism, the lower end of the outer spiral rolling way is connected with the lower end of the lower free rolling way, and the upper end of the lower free rolling way serves as an inlet of the sphere conveying mechanism. The sphere conveying mechanism of the device for machining the high-precision sphere has the advantages that circulating machining of the sphere is achieved, the machining efficiency is high, a machining path can be controlled quite accurately, and the machining uniformity is high.

Description

technical field [0001] The invention relates to high-precision sphere processing equipment, in particular to a sphere conveying mechanism. Background technique [0002] High-precision balls are important components in roundness meters, gyroscopes, bearings and precision measurement, and are often used as the benchmark for precision measurement, and play a very important role in precision equipment and precision machining. Especially in ball bearings, it is a key part of ball bearings. The accuracy of bearing balls (spherical deviation, ball diameter variation and surface roughness) directly affects the technical indicators of ball bearings such as motion accuracy, noise and life. Affect the performance of equipment and instruments. Compared with the traditional bearing steel ball material (GCr15), advanced ceramic materials such as silicon nitride have wear resistance, high temperature resistance, corrosion resistance, non-magnetism, low density (about 40% of bearing steel)...
