Technical Field
[0001] The utility model relates to the technical field of fine boring cutters, in particular to a high-precision fine boring cutter with fine adjustment function. Background Technique
[0002] A boring cutter is a kind of boring tool, generally with a round shank, and there are also square tool holders for larger workpieces. The most common applications are internal hole machining, reaming, profiling, etc. It has one or two cutting parts and is a tool specifically used for rough machining, semi-finishing or finishing of existing holes. The boring cutter can be used on a boring machine, a lathe or a milling machine.
[0003] However, during the use of traditional boring cutters, the position needs to be adjusted according to the processing process. Currently, the commonly used method is mainly to directly adjust the movement of the fine boring cutter. When adjusting the tool in this existing way, there is a certain error, and the situation of over-adjusting or under-adjusting will occur, which will affect the processing accuracy of the finished product. Therefore, there is an urgent need for a high-precision fine boring cutter with fine adjustment function to solve such problems. Content of the Utility Model

A first connecting rod 9 is fixed to one outer wall of the first slider 14. The first connecting rod 9 passes through the first notch 7 and is equipped with a pointer 8, and the pointer 8 cooperates with the scale number 3. When the first slider 14 moves, at this time the pointer 8 will move on the outer wall of the scale number 3 to achieve fine adjustment.
[0025] In this embodiment, a first rotating handle 10 is provided on one outer wall of the first mounting shell 2, and the first rotating handle 10 is fixed to one end of the first lead screw 11. A quick-release mechanism for quickly detaching the boring tool body 4 is provided inside the second mounting shell 5.
[0026] In this embodiment, the quick-release mechanism includes a bidirectional lead screw 16 rotatably connected to both sides of the inner wall of the second mounting shell 5. Two second sliders 18 adapted to slide on the outer wall of the bidirectional lead screw 16 are provided. A third connecting rod 19 is fixed to the bottom of the second slider 18. The bottoms of the two third connecting rods 19 are fixed to a clamping block 20. The surfaces of the two clamping blocks 20 facing each other are adapted to the outer wall of the boring tool body 4. Rotate the second rotating handle 15, and at this time the clamping block 20 will loosen the boring tool body 4.
[0027] In this embodiment, guide rods 17 are fixed to both inner walls of the second mounting shell 5, and the guide rods 17 penetrate through the two second sliders 18.
[0028] In this embodiment, a second rotating handle 15 is provided on one outer wall of the second mounting shell 5, and the second rotating handle 15 is fixed to one side of the bidirectional lead screw 16. A limiting mechanism is provided on the other side of the second mounting shell 5.
[0029] In this embodiment, the limiting mechanism includes a ratchet wheel 21 fixed to the outer wall of the other side of the bidirectional lead screw 16.

[0030] Working principle: When in use, with a quick-release mechanism set, first pull the sliding rod 23 to move the pawl 22 away from the ratchet wheel 21. At this time, rotate the second rotating handle 15, and the second rotating handle 15 will drive the bidirectional lead screw 16 to rotate. At this time, the bidirectional lead screw 16 will drive the two second sliders 18 to move away from each other, and the clamping block 20 will loosen the boring tool body 4, thus achieving the effect of quickly disassembling the boring tool body 4. When installation is required, place the top of the outer wall of the boring tool body 4 between the two clamping blocks 20. At this time, rotate the second rotating handle 15, and the second rotating handle 15 will drive the two clamping blocks 20 to move closer to each other. At this time, the ratchet wheel 21 and the pawl 22 will limit the bidirectional lead screw 16 to prevent the boring tool body 4 from loosening and falling off during work. With an adjustment mechanism set, when fine adjustment of the boring tool body 4 is required, rotate the first rotating handle 10 at this time. The first rotating handle 10 will drive the first lead screw 11 to rotate. At this time, the first lead screw 11 will drive the first slider 14 to move. At this time, the first slider 14 will drive the second connecting rod 13 to move. At this time, the second connecting rod 13 will drive the second mounting shell 5 to move. When the first slider 14 moves, the first slider 14 will drive the first connecting rod 9 to move in the first notch 7. At this time, the first connecting rod 9 will drive the pointer 8 to move. By observing the distance required for the pointer 8 to move to the scale number 3, the effect of fine-tuning the boring tool body 4 is achieved.
