Description

Technical Field

[0001] The utility model relates to the technical field of bolt end chamfering, in particular to an end chamfering device for bolt processing. Background Art

[0002] Bolt end chamfering refers to the bevel processing at the end of the bolt (usually the part exposed from the nut) to form a bevel. This beveled angle is mainly to avoid the edge of the bolt end being too sharp, thereby preventing possible scratches or cuts during use, causing damage to the surrounding surface or personnel. The bolt chamfering operation can be performed by machine processing to ensure the size and shape of the chamfer is standardized, while ensuring operational efficiency and chamfering accuracy.

[0003] At present, in the existing technology, most devices can clamp the bolts and then perform chamfering. Since bolts of different lengths need to be processed, the limiting structure on the clamping structure cannot be flexibly adjusted and the clamping structure needs to be replaced, resulting in poor practicality of the device. In view of this, we propose an end chamfering device for bolt processing. Utility Model Content
