Description

Technical Field

[0001] This utility model relates to the field of chamfering tool technology, specifically a high-hardness chamfering tool for machining cylindrical holes. Background Technology

[0002] A countersunk drill, also known as a countersunk head drill, is a type of drill used to countersunk tapered holes. It can be used to deburr, chamfer, and create countersunk recesses at the hole opening. However, a guide hole is required for subsequent machining. The tapered hole is wider at the top and narrower at the bottom. To place a tapered flat-head screw, both a countersunk hole and a tapered recess need to be machined.

[0003] According to a chamfering tool disclosed on the patent website (authorization announcement number: CN217799397U), "This utility model discloses a chamfering tool, including a chamfering tool body, which includes a tool shank, a tool head, and a cooling rod. A cooling rod is fixedly installed at one end of the tool shank, and a tool head is fixedly installed at the end of the cooling rod away from the tool shank. A micro water pump and a lubricant storage tank are respectively fixedly installed at both ends of one side of the inner wall of the cooling rod. Several lubrication holes are opened on the surface of the tool head. The tool shank includes a length rod, a fixing plate, and a threaded post. This utility model of a chamfering tool, by setting a micro water pump and a lubricant storage tank, allows the chamfering tool body to process the workpiece. When processing the workpiece, the micro water pump draws lubricant from the lubricant storage tank through an extraction pipe. The drawn lubricant lubricates the surface of the tool head through the lubrication holes, reducing friction between the chamfering tool and the workpiece, while cooling the tool head to prevent deformation under high temperature and extend the service life of the chamfering tool."

[0004] Based on the above, the applicant believes the following deficiencies exist:

[0005] This chamfering cutter includes a chamfering cutter body. Lubricant for cooling and lubrication is drawn from a lubricant storage tank via an extraction pipe. The extracted lubricant lubricates the cutter head surface through lubrication holes, reducing friction between the chamfering cutter and the workpiece, while simultaneously cooling the cutter head to prevent deformation under high temperatures and extend its service life. Most chamfering cutters are integrated models; after prolonged use, they may become damaged and require complete disassembly and replacement, which is inconvenient and consumes a significant amount of resources.

A second adjusting column 44 is fixedly connected inside the outer sleeve 43. Limiting slots 45 are provided on the surfaces of the first adjusting column 42, the outer sleeve 43, and the second adjusting column 44. Limiting bolts 46 are provided inside the limiting slots 45. When the chamfering blade body 1 is used, it is often necessary to adjust the length of the chamfering blade body 1 to adapt to various working environments. By removing the limiting bolts 46, the first adjusting column 42 is pulled out from inside the outer sleeve 43, and the limiting bolts 46 are inserted into the corresponding limiting slots 45 to achieve limiting, thereby completing the length adjustment of the chamfering blade body 1.
