[0037] In this embodiment, the transmission assembly includes a C-shaped plate 15 fixedly mounted on the end of the rotating platform 6 away from the rotating seat 5. The outer surface of the C-shaped plate 15 is penetrated with a mounting hole 16. The inner wall of the mounting hole 16 is installed with a one-way bearing 18. The interior of the mounting hole 16 is installed with a rotating tube 17 that can rotate in one direction through the one-way bearing 18.

A limit groove 23 matching the limit block 22 is provided on the outer periphery of the feed screw 14 near one end of the rotating tube 17, and the limit block 22 is slidably installed on the inner wall of the limit groove 23. A card groove 24 matching the limit block 22 is provided on the inner wall of the rotating tube 17 in the circumferential direction. A compression spring 25 is sleeved on the outer surface of the feed screw 14, and the compression spring 25 is arranged between the dial ring 21 and the end of the rotating platform 6.

[0038] When the rotating platform 6 swings, it will drive the rotating tube 17 to move synchronously through the C-shaped plate 15, so that the transmission gear 19 installed on the rotating tube 17 rolls on the arc rack 20, so that the transmission gear 19 can drive the rotating tube 17 to rotate synchronously, so that the rotating tube 17 drives the feed screw 14 to rotate through the meshing assembly, so that the feed screw 14 can slowly drive the slider 8 threadedly connected to it to move toward the direction of the grinding wheel 4, so that the tool head of the inner arc groove boring tool installed on the slider 8 through the hand-tight drill chuck 10 can slowly feed toward the grinding surface of the grinding wheel 4, without the need for manual feeding operations, and the operation is more convenient.

[0042] During the grinding operation, the dust collector 29 absorbs the dust generated during the grinding through the dust hood 30 to prevent the dust from flying around and polluting the surrounding environment.

[0043] A method for using a high-precision adaptive boring tool grinding device comprises the following steps:

[0044] S1: inserting the inner arc groove boring tool to be ground into the hand-tight drill chuck 10, adjusting the tool head to the grinding position by the rays emitted by the laser emitter 12, and then tightening the hand-tight drill chuck 10 to fix the inner arc groove boring tool;

[0045] S2: Rotate the stopper 27 upward to push the shifting ring 21 in the direction of the feed screw 14. After the shifting ring 21 passes the position of the stopper 27, lower the stopper 27 so that the stopper 27 blocks the shifting ring 21, so that the limit block 22 installed on the inner wall of the shifting ring 21 is separated from the slot 24 provided on the inner wall of the rotating tube 17. At this time, the shifting ring 21 can be rotated to drive the feed screw 14 to rotate, so that the feed screw 14 drives the slider 8 threadedly connected thereto to move in the direction of the grinding wheel 4 until the cutter head of the inner arc groove boring cutter abuts against the grinding surface of the grinding wheel 4, so that the grinding wheel 4 can grind the cutter head;

[0046] S3: After adjusting the position of the cutter head, lift the stopper 27 to reset the ring 21 under the elastic force of the compression spring 25, so that the limit block 22 installed on the inner wall of the ring 21 is inserted into the slot 24 provided on the inner wall of the rotating tube 17, so that the feed screw 14 and the rotating tube 17 are connected as one body, so as to rotate synchronously later;

[0047] S4: The rotating seat 5 and the rotating platform 6 are driven by the stepping motor 13 to swing back and forth as a whole, so that the inner arc groove boring tool installed on the rotating platform 6 swings accordingly, so that the tool head of the inner arc groove boring tool can make an arc motion on the grinding surface of the grinding wheel 4, so that the grinding wheel 4 grinds the tool head into an arc shape;

[0048] S5: While the rotating platform 6 is swinging, it will drive the rotating tube 17 to move synchronously through the C-shaped plate 15, so that the transmission gear 19 installed on the rotating tube 17 rolls on the arc rack 20, so that the transmission gear 19 can drive the rotating tube 17 to rotate synchronously, and the rotating tube 17 drives the feed screw 14 to rotate through the meshing assembly, so that the feed screw 14 can slowly drive the slider 8 threadedly connected to it to move toward the direction of the grinding wheel 4, so that the tool head of the inner arc groove boring tool installed on the slider 8 through the hand-tight drill chuck 10 can slowly feed toward the grinding surface of the grinding wheel 4.

[0049] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the inner arc groove boring tool to be ground is inserted into the hand-tight drill chuck 10, the cutter head is adjusted to the grinding position by the beam emitted by the laser emitter 12, and then the hand-tight drill chuck 10 is tightened to fix the inner arc groove boring tool. At this time, the stop rod 27 is rotated upward to push the shift ring 21 in the direction of the feed screw 14. When the shift ring 21 passes over the stop rod 27, the shift ring 21 is moved to the position of the feed screw 14. After that, the stopper 27 is lowered to block the shifting ring 21, so that the limit block 22 installed on the inner wall of the shifting ring 21 is separated from the slot 24 provided on the inner wall of the rotating tube 17. At this time, the shifting ring 21 can be rotated to drive the feed screw 14 to rotate, so that the feed screw 14 drives the slider 8 threadedly connected thereto to move toward the grinding wheel 4 until the cutter head of the inner arc groove boring cutter abuts against the grinding surface of the grinding wheel 4, so that the grinding wheel 4 can grind the cutter head;

[0050] After adjusting the position of the cutter head, lift the stopper 27 to reset the ring 21 under the elastic force of the compression spring 25, so that the limit block 22 installed on the inner wall of the ring 21 is inserted into the slot 24 provided on the inner wall of the rotating tube 17, so that the feed screw 14 and the rotating tube 17 are connected as one body, so as to rotate synchronously later;

[0051] During the grinding operation, the rotating seat 5 and the rotating platform 6 are driven by the stepping motor 13 to swing back and forth as a whole, so that the inner arc groove boring tool installed on the rotating platform 6 swings accordingly, so that the tool head of the inner arc groove boring tool can make an arc motion on the grinding surface of the grinding wheel 4, so that the grinding wheel 4 can grind the tool head into an arc shape, and there is no need to manually hold the inner arc groove boring tool for grinding operation, which avoids the inner arc groove boring tool being held unsteadily during manual grinding operation, resulting in large grinding errors;

[0052] When the rotating platform 6 swings, it will drive the rotating tube 17 to move synchronously through the C-shaped plate 15, so that the transmission gear 19 installed on the rotating tube 17 rolls on the arc rack 20, so that the transmission gear 19 can drive the rotating tube 17 to rotate synchronously, so that the rotating tube 17 drives the feed screw 14 to rotate through the meshing assembly, so that the feed screw 14 can slowly drive the slider 8 threadedly connected to it to move toward the direction of the grinding wheel 4, so that the tool head of the inner arc groove boring tool installed on the slider 8 through the hand-tight drill chuck 10 can slowly feed toward the grinding surface of the grinding wheel 4, without the need for manual feeding operations, and the operation is more convenient.

[0053] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
