Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinders, and more specifically, to a fixing device for centerless grinders. Background Art

[0002] A centerless grinder is a machine tool used for precision machining, mainly used for grinding the outer circle of workpieces. This type of grinder is widely used in the field of mechanical processing, especially in situations where high precision and high surface quality are required. However, this type of centerless grinder has the problem of angular shapes when machining parts, and the main reason is that the center height of the part is not high enough or the center height of the part is too high.

[0003] Currently, this can be done by raising the center of the part or lowering the center height appropriately. However, adjusting the center of the part requires high precision and the distance to be raised needs to be accurately measured. If the measurement is wrong, the workpiece will not meet the standards and will be scrapped.

[0004] Therefore, a fixing device for centerless grinder is proposed to solve the measurement problem, ensure machining accuracy, improve production efficiency and reduce workpiece defects. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a fixing device for a centerless grinder which can ensure machining accuracy, improve production efficiency and reduce workpiece defects.
