Abstract

The invention discloses a self-adaptive grinding tool for a vertical crankshaft and relates to the technical field of engine part grinding tools. The grinding tool comprises a positioning device for vertically clamping the crankshaft and a grinding device located on one side of the positioning device and used for self-adapting to the outline of the crankshaft. The crankshaft grinding tool solves the problems that in order to ensure the fastening of a crankshaft, the stress influence on the crankshaft is ignored in the grinding tool in the prior art; in order to achieve the purpose that when the crankshaft face is ground, the same grinding amount of the crankshaft face cannot be guaranteed; when parts with different widths of the crankshaft are ground, the displacement amount needs to be frequently adjusted; and due to limitation of a grinding wheel, the side wall of the crankshaft can be ground in an auxiliary mode manually with the help of an auxiliary tool.

Description

technical field

[0001] The invention relates to the technical field of grinding tools for engine components, in particular to an adaptive grinding tool for vertical crankshafts. Background technique

[0002] At present, the crankshaft grinding and cleaning equipment in the prior art mainly has the following major problems: 1. Most of the existing crankshaft grinding machines are manual loading and unloading and workpiece transfer, which have a low degree of automation and take up a lot of human resources. When some crankshaft grinders transfer workpieces, due to the limitation of the unit efficiency of the grinding device, they can generally only complete one or two crankshaft transfers at a time, and the work efficiency is low. If multiple devices are used, the area will be too large. Can not satisfy the production requirement of production, 3, the layout of each part in the existing crankshaft grinder equipment is unreasonable, causes the overall structure compactness of e...
