Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to an alloy drill-reamer integrated cutting tool with convenient cutting head replacement. Background Art

[0002] A tool is a common tool used in daily life and can also be a weapon. In mechanical manufacturing, the tool used for cutting is called a cutting tool. The vast majority of tools are machine-made, but there are also hand-made tools. Since the tools used in mechanical manufacturing are basically used to cut metal materials, the term "tool" is generally understood to mean metal cutting tools. The cutter head of an alloy drill-reamer is usually fixed and installed by screws, and tools are required to disassemble the cutter head, which makes it inconvenient to replace the cutter head. Therefore, an alloy drill-reamer with easy-to-replace cutter head is proposed to facilitate the replacement of the cutter head. Utility Model Content

Rod, the two blocks are provided with screw holes adapted to the bidirectional screw rod, the two sides of the connecting block are provided with slots adapted to the ends of the blocks, two bearings are fixed in the support, the bidirectional screw rod is connected to the inner rings of the two bearings, blocks are fixed on both sides of the limit block, plug rods are provided above the two knobs, through holes adapted to the plug rods are provided on the two blocks, plug blocks are fixed to the bottom ends of the two plug rods, slots adapted to the bottom ends of the plug blocks are provided on the two knobs, and springs are sleeved on the two plug rods.

[0005] By adopting the above technical solution, the two rods are lifted up, and the bottom ends of the two plug blocks are disengaged from the two knobs. The knob is rotated, and the knob drives the two-way screw rod to rotate, and the ends of the two blocks are disengaged from the slots on both sides of the connecting block. The drill reamer head can be removed and replaced together with the connecting block by moving down. During installation, the two rods are lifted up, the connecting block at the top of the drill reamer head is inserted into the slot at the bottom of the support, and then the knob is rotated. The two-way screw rod rotates accordingly, and the ends of the two blocks are inserted into the slots on both sides of the connecting block. The two rods are released, and the two springs push the two blocks to move downward, and the bottom ends of the two blocks are inserted into the slots on the two knobs to prevent the drill reamer head from loosening due to the rotation of the knob and the two-way screw rod.

[0006] Specifically, positioning blocks are fixed on both sides of the connecting block, and two slots adapted to the positioning blocks are provided at the bottom end of the support.

[0007] By adopting the above technical solution, during installation, the positioning block cooperates with the slot at the bottom end of the support, which facilitates the positioning of the connecting block.

[0008] Specifically, a protective cover is provided below the limiting block, and the protective cover is rotatably connected to the connecting block.

[0009] By adopting the above technical solution, the protective cover can block the debris moving upward along the drill and reamer head during the drilling and reaming process. The protective cover is rotatably connected to the connecting block to avoid synchronous rotation of the protective cover and the connecting block, thereby preventing the debris from being easily thrown out and disrupting the working environment.

[0010] Specifically, counterweight blocks are provided on both sides of the drill reamer head, and the two counterweight blocks are connected to the protective cover.

[0011] By adopting the above technical solution and setting the counterweight block, the deadweight of the protective cover can be increased, thereby improving the stability of the protective cover.

[0012] Specifically, the limiting block is welded to the tool handle, and the support is welded to the limiting block.
