Abrasive belt grinding device for crankshaft

Abstract

The invention provides an abrasive belt grinding machine for a crankshaft. The abrasive belt grinding machine for the crankshaft comprises an inverted U-shaped shell which is internally provided with an abrasive belt grinding machine body, wherein the abrasive belt grinding machine body comprises abrasive belt reeling shafts which are respectively arranged at two sides of the lower part of the inverted U-shaped shell, an abrasive belt bypasses a pinch roller on the upper part of the inverted U-shaped shell and is wound on the abrasive belt reeling shafts on two sides of the lower part of the inverted U-shaped shell, and each abrasive belt reeling shaft is connected with a driving motor. According to the abrasive belt grinding machine provided by the invention, external grinding of a crankshaft for a large-size ship can realized, grinding can be carried out on any large sleeping carriage, and the glossiness can be improved by one or two grades on the basis of the glossiness of the machining surface of an original machine. Compared with a special complicated grinding machine, the abrasive belt grinding machine disclosed by the invention has the advantages that the manufacturing cost is only 1 / 1000 that of the special completed grinding machine, and complicated process and operation skills are omitted.

Description

[0001] Technical field: [0002] The invention relates to an abrasive belt grinding device for a crankshaft, belonging to the technical field of abrasive belt grinding equipment. [0003] Background technique: [0004] Crankshafts have different sizes, specifications and uses, with great differences and complex shapes. Crankshaft machining is generally done by expensive special-purpose crankshaft lathes and grinders. Large-scale crankshafts on large-scale marine diesel engines have more crankshafts, large turning diameters, overlength, and overweight. They have always been a major technical bottleneck in China's shipbuilding industry. Only four or five countries in the world have the strength and ability to manufacture large-scale marine crankshafts. China has been constrained in the manufacture of crankshafts in the process of striving towards the goal of becoming a world shipbuilding power. Blocked and ripped off by technology. It was not until more than ten years ago tha...

AI Technical Summary

Problems solved by technology

Therefore, the crankshaft grinder is very expensive, but this kind of grinder is only used for small and medium-sized overall forged crankshafts with short eccentricity, that is, short stroke.
