Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically a deep-hole alloy spiral reamer. Background Technology

[0002] A drill bit is a cutting tool used in general drills or drilling machines to cut circular holes. The basic principle of a drill bit is to rotate the cutting edge, cut the workpiece, and then remove the drill chips through the drill grooves. Commonly used drill bits include twist drills, flat drills, center drills, deep hole drills, nesting drills, and internally cooled drill bits. Although reamers and countersinks cannot drill holes in solid materials, they are conventionally classified as drill bits. Internally cooled drill bits usually have 1-2 through holes from the shank to the cutting edge, through which compressed air, oil, or cutting fluid passes, cooling the tool and workpiece and flushing away chips, making them particularly suitable for deep hole machining.

[0003] However, when using existing drill bits, the installation process typically involves using a tool to rotate the drill chuck to hold and fix the drill bit. When the drill bit is damaged during operation, such as chipping, and needs to be disassembled and replaced, the replacement operation still requires rotating the drill chuck, which is quite complicated. In addition, the position of the drill bit cannot be adjusted. Therefore, we propose a more convenient and practical deep hole alloy spiral reamer to meet the usage requirements.

[0016] In machining processes, reamers are required. The reamer provided by this utility model is specifically designed for metal parts machining operations. When using this equipment for machining operations, it is essential to ensure that all components of the mounting mechanism 7 are securely connected when installing the reamer. Before machining, a comprehensive inspection of the reamer should be conducted, carefully checking whether the connection between the tool holder 1 and the tool head 3 is tight and without looseness, and whether the chip removal groove 4 is clean and unobstructed. If there are impurities in the chip removal groove 4, the fluid injection status of the injection hole 6 should be monitored at all times to ensure that the coolant or lubricant can be continuously and stably injected, and the injection amount should be moderate. When adjusting the feed speed and rotation speed of the reamer, the parameters should be reasonably selected according to the material, thickness, and machining requirements of the metal parts.

[0017] like Figures 1-3 As shown, this utility model provides a technical solution: a deep hole alloy spiral reamer, including a shank 1, a stepped groove 2 on the outer wall of the shank 1, a cutter head 3 fixedly connected to one end of the shank 1, a chip removal groove 4 on the outer wall of the cutter head 3, a cutting edge 5 fixedly connected to one end of the cutter head 3, and a mounting mechanism 7 provided at one end of the shank 1. The mounting mechanism 7 includes a mounting plate 701, through holes on both sides of the mounting plate 701, and a first bolt 702 installed in the through holes. One end of the first bolt 702 is in contact with the shank 1.

[0018] like Figure 2 As shown, a liquid injection hole 6 is provided through one side of the knife rod 1, and an installation tube 8 is slidably connected to the outer wall of one end of the knife rod 1. A partition plate 9 is fixedly connected to the inner wall of one side of the installation tube 8. Installation frames 10 are provided on both sides of the knife rod 1, and the installation frames 10 and the installation plate 701 are compatible with each other.

[0019] It is important to note that during use, one end of the tool holder 1 is first connected to the power unit via a connecting pipe. The power unit is then started to rotate the tool holder 1 and the cutter head 3, inserting the cutter head 3 into the deep hole to be reamed. The cutting edge 5 cuts the hole wall, and the chips generated during reaming are discharged from the hole through the chip removal groove 4 on the outer wall of the cutter head 3 to prevent chip accumulation from affecting the machining. If cooling or lubrication is required, coolant or lubricant can be injected through the injection hole 6 on the tool holder 1 for cooling. The connection and disassembly of the tool holder 1 are convenient. When the cutter head 3 or the tool holder 1 is worn or damaged, the relevant parts can be quickly disassembled and replaced, reducing maintenance costs and time and improving equipment utilization.

[0020] like Figure 3 As shown, a slot is provided on one side of the mounting plate 701, and a sliding block 703 is slidably connected in the slot. Multiple equidistant limiting holes 704 are provided on both sides of the top of the mounting plate 701. The limiting holes 704 penetrate the sliding block 703. A second bolt 705 is installed in the limiting hole 704. One end of the second bolt 705 is adapted to the sliding block 703. A connecting block 706 is fixedly connected to the center of the top of the sliding block 703. The connecting block 706 is slidably connected to the partition plate 9. A through hole is provided on the top of the connecting block 706. A third bolt 707 is installed in the through hole and penetrates the mounting tube 8.

[0021] It should be noted that during use, firstly, the mounting plate 701 is inserted into the mounting frame 10 of the tool bar 1, and the tool bar 1 is initially fixed by tightening it with the first bolt 702. Next, the sliding block 703 on the mounting plate 701 is pushed to slide in the groove. After adjusting to the appropriate position, the second bolt 705 is screwed into the corresponding limiting hole 704 and passed through the sliding block 703 for fixation. Then, the mounting tube 8 is fitted onto the outer wall of one end of the tool bar 1, so that the partition 9 on the inner wall of the mounting tube 8 corresponds to the connecting block 706. Finally, the third bolt 707 is passed through the through hole at the top of the connecting block 706 and screwed into the mounting tube 8 to firmly install the entire mounting mechanism 7 on the tool bar 1 and the mounting tube 8. The mounting mechanism 7 can achieve fine adjustment of the position of the mounting plate 701 on the tool bar 1, thereby ensuring the tightness and stability of the connection between the mounting mechanism 7 and the tool bar 1.

[0022] During use, firstly, insert the mounting plate 701 into the mounting frame 10 of the tool bar 1, and use the first bolt 702 to tighten the tool bar 1 for initial fixation. Next, push the sliding block 703 on the mounting plate 701 to slide in the groove. After adjusting to the appropriate position, screw the second bolt 705 into the corresponding limiting hole 704 and through the sliding block 703 for fixation. Then, put the mounting tube 8 on the outer wall of one end of the tool bar 1, so that the partition 9 on the inner wall of the mounting tube 8 corresponds to the connecting block 706. Use the third bolt 707 to pass through the through hole at the top of the connecting block 706 and screw it into the mounting plate 706. The tube 8 is connected to the power unit, and one end of the tool holder 1 is connected to the power unit through the connecting tube. The power unit is started to drive the tool holder 1 and the tool head 3 to rotate, and the tool head 3 is inserted into the deep hole to be reamed. The cutting edge 5 cuts the hole wall. The chips generated by reaming are discharged out of the hole through the chip removal groove 4 on the outer wall of the tool head 3 to prevent the chips from accumulating and affecting the processing. If cooling or lubrication is required, coolant or lubricant can be injected through the injection hole 6 on the tool holder 1 for cooling. The device can flexibly adjust the position of the connecting block 706 according to different working conditions and needs to adapt to different installation requirements.
