Description

Technical Field

[0001] The present application relates to the technical field of deep hole drilling, and in particular to a deep hole drill that is easy to quickly disassemble and assemble. Background Art

[0002] In mechanical processing, drilling is a common process, and deep hole drills are often needed to drill holes in some workpieces. Since the drill bit needs to extend into the workpiece during drilling, the cutting part of the drill bit is very prone to friction and breakage. Ordinary deep hole drills are an integrated structure of drill rod and drill bit. When the front part of such a drill bit structure is damaged, the entire drill bit and drill rod structure will be directly scrapped, and then it needs to be disassembled and replaced.

[0003] After searching, the China Patent Network disclosed a deep hole drill that is easy to install, and its authorization announcement number is CN213560097U. This patent is provided with a fixing column, a connecting spring, a clamping rod and a clamping slot. When the drill bit needs to be installed, the fixing column is first inserted into the fixing slot, and the handle is loosened. The clamping rod can be clamped into the clamping slot under the action of the connecting spring to fix the fixing column, thereby achieving a good fixing effect. The installation process is relatively simple, and there is no need to frequently tighten the bolts for fixing, and no need to spend a lot of installation time. It is easy to disassemble and install, meeting people's usage needs. Although this patent makes it convenient to disassemble and replace the drill bit, its sealing effect is poor. During the drilling process of the drill bit, debris and waste can easily enter the connecting column, which brings inconvenience to the disassembly of the drill bit and needs to be improved. For this reason, we propose a deep hole drill that is easy to disassemble and assemble quickly to solve the above problems.
