Blade grinding jig and manufacturing method of blade grinder

1. The utility model relates to the technical field of blade processing, in particular to a blade grinding jig and a blade grinder.

Background technique:

2. The processing of cylinder head valve seat is a difficult point in automobile engine manufacturing, and multi-angle valve blades are usually used for processing. Since the cylinder head valve seat is mostly made of difficult-to-process powder metallurgical materials, the processing accuracy is high and the blade consumption is large. In order to save processing costs, the valve blades need to be ground after use. In the tool grinding process, it is necessary to strictly ensure the grinding angle of the valve blades.

3. In the process of grinding, grinding fixtures are often used to clamp the valve blades for grinding on the blade grinder. However, conventional grinding fixtures have poor clamping accuracy, poor consistency of blade grinding angles, and low pass rate of valve blade grinding.
