Description

Technical Field

[0001] The present application relates to the field of reamers, and in particular to a blade mounting structure of a reamer. Background Art

[0002] A reamer is a rotary tool with one or more teeth used to remove a thin metal layer from the processed surface of a hole. The reamer reams a hole that has been drilled (or expanded) on a workpiece, mainly to improve the processing accuracy of the hole and reduce its surface roughness. After being processed by a reamer, the hole can obtain a precise size and shape.

[0003] When the cutting edge of the reamer is damaged, the entire reamer needs to be replaced, which increases the cost of use. The existing reamer is equipped with a detachable blade, so when the blade is damaged, the damaged blade can be replaced. However, the blade mounting structure of the existing reamer lacks a heat dissipation structure. A large amount of heat will be generated on the blade during the metal cutting process. The accumulation of heat will affect the structural strength of the blade to a certain extent. For this reason, we propose a blade mounting structure for a reamer. Utility Model Content
