[0020] Embodiment 1: Figures 1 to 8As shown, a preferred embodiment of the present invention provides a reamer tool with an indexable machine-clamped blade, including a reamer rod 1 and a reamer blade 2, a plurality of reamer blade slots 11 are provided on the reamer rod 1, a mounting slot 12 is provided on the reamer blade slot 11 side of the reamer rod 1, a slot 13 connected to the mounting slot 12 is provided on the side wall of the reamer blade slot 11, a plug plate 14 is movably plugged into the slot 13, one side of the plug plate 14 extends into the interior of the mounting slot 12, and the other side of the plug plate 14 is fixedly connected to the reamer blade 2, The inner cavity of the mounting groove 12 is provided with a limit assembly 3 for fixing the plug board 14. The limit assembly 3 includes a rotating rod 31 rotatably connected to the bottom of the inner cavity of the mounting groove 12, a limit sleeve 32 is fixedly connected to the circumferential outer wall of the rotating shaft, and a plurality of groups of limit plates 33 corresponding to the plug board 14 are fixedly connected to the circumferential outer wall of the limit sleeve 32. The limit plate 33 is fixedly connected to an arc plate 34 at one end away from the limit sleeve 32. The plug board 14 is located on one side of the inner cavity of the mounting groove 12 and is provided with an arc groove adapted to the arc plate 34. 141, the arc plate 34 is movably connected with the arc groove 141, a support plate 15 is arranged between two adjacent limit plates 33, the upper surface of the support plate 15 is fixedly connected with the bottom of the inner cavity of the installation groove 12, an arc spring 16 is arranged between the support plate 15 and the limit plate 33, the two ends of the arc spring 16 are respectively fixedly connected with the support plate 15 and the limit plate 33, a dust cover 17 is threadedly connected to the end of the installation groove 12, the rotating rod 31 passes through the dust cover 17 and is connected to the rotation, and the rotating rod 31 is away from A hexagonal screw hole 311 is provided on one side of the bottom of the inner cavity of the installation groove 12. Preferably, a limiting groove 18 is provided on the bottom of the inner cavity of the installation groove 12. The inner cavity of the limiting groove 18 is slidably connected with a limiting plate 181. A limiting spring 182 is provided between the limiting plate 181 and the limiting groove 18. Both ends of the limiting spring 182 are respectively fixedly connected to the limiting plate 181 and the limiting groove 18. The side of the limiting plate 181 away from the limiting spring 182 is fixedly connected to a limiting stopper 183, and one side of the limiting stopper 183 is provided with a chamfer.

[0021] When the reamer blade 2 is installed, the wrench is first inserted into the hexagonal screw hole 311, and then the wrench is rotated. The wrench drives the rotating rod 31 to rotate, and the rotating rod 31 drives the limiting sleeve 32 to rotate. The limiting sleeve 32 drives the limiting plate 33 and the arc plate 34 to rotate. Then, the plug plate 14 is inserted into the slot 13 until the side wall of the reamer blade 2 abuts against the reamer blade slot 11. After multiple plug plates 14 are inserted into the slot 13, the rotating rod 31 is reset by the wrench again. The rotating rod 31 drives the limiting sleeve 32, the limiting plate 33 and the arc plate 34 to rotate and reset. The arc plate 34 squeezes the limiting block 183 during the rotation process. The limiting block 183 drives the limiting block 181 to move in the limiting slot 18. At this time, the limiting spring 182 is compressed. When the arc plate 34 is inserted into the arc slot 141, the limiting spring 182 is compressed.

Compared with the existing method of installing the blade one by one by bolts, the present invention only needs to rotate the rotating rod 31 to fix multiple groups of reamer blades 2, which is not only trouble-free and labor-saving, but also more efficient. At the same time, in order to prevent the reamer blade 2 from loosening due to vibration during operation, thereby causing the reamer blade 2 to fall out, the arc spring 16 located between the support plate 15 and the limit plate 33 presses the limit plate 33 tightly under the action of its own elastic force, effectively preventing the reamer blade 2 from falling out due to the loosening of the rotating rod 31, thereby greatly improving the safety of work.

[0022] Embodiment 2, as Figure 1-Figure 8 As shown, on the basis of embodiment 1, the present invention proposes a technical solution: further, the plug plate 14 is fixedly connected to the side away from the reamer blade 2 with an insert block 142, the insert block 142 is provided with a first chamfer 1421 on the side away from the plug plate 14, and an anti-slip component 4 is provided on the outer side of the insert block 142. The anti-slip component 4 includes an anti-slip frame 41 fixedly connected to the bottom of the inner cavity of the mounting groove 12, and anti-slip plates 42 are symmetrically arranged on the inner side of the anti-slip frame 41. A second chamfer 421 is provided on the side of the anti-slip plate 42 close to the plug plate 14, and an anti-slip spring 43 is arranged between the anti-slip plate 42 and the side wall of the anti-slip frame 41, and the two ends of the anti-slip spring 43 are respectively fixedly connected to the anti-slip plate 42 and the anti-slip frame 41, and the first chamfer 1421 is adapted to the second chamfer 421.

[0023] In this embodiment, when the plug plate 14 is inserted into the slot 13, the plug plate 14 drives the plug block 142 to be inserted between the two anti-slip plates 42. During the insertion of the plug block 142, the first chamfer 1421 on the wiper block 143 abuts against the second chamfer 421 on the anti-slip plate 42. As the plug block 142 is inserted, the two anti-slip plates 42 move to both sides of the anti-slip frame 41 respectively. The anti-slip plates 42 squeeze the anti-slip springs 43 during the movement. Under the action of the elastic force of the anti-slip springs 43 themselves, the two anti-slip plates 42 clamp the plug block 142 to prevent it from falling during the installation of the reamer blade 2, thereby preventing the reamer blade 2 from being damaged, thereby saving production costs.

[0024] When the reamer blade 2 is installed, first insert the wrench into the hexagonal screw hole 311, and then turn the wrench, the wrench drives the rotating rod 31 to rotate, the rotating rod 31 drives the limiting sleeve 32 to rotate, the limiting sleeve 32 drives the limiting plate 33 and the arc plate 34 to rotate, and then the plug plate 14 is inserted into the slot 13 until the side wall of the reamer blade 2 abuts against the reamer blade slot 11, and after multiple plug plates 14 are inserted into the slot 13, the rotating rod 31 is reset by the wrench again, the rotating rod 31 drives the limiting sleeve 32, the limiting plate 33 and the arc plate 34 to rotate and reset, and the arc plate 34 squeezes the limiting stopper 183 during the rotation process, and the limiting stopper 183 drives the limiting stopper 181 to move in the limiting slot 18, at this time, the limiting spring 182 is compressed, and when the arc plate 34 is inserted into the arc slot 141, the limiting spring 182 The limit stopper 183 is used to limit the arc plate 34 to prevent it from rotating. At the same time, the arc plate 34 is inserted into the arc groove 141 to generate an inward pulling force, thereby fixing the reamer blade 2. Compared with the existing method of installing the blades one by one by bolts, the present invention only needs to rotate the rotating rod 31 to fix multiple groups of reamer blades 2, which is not only labor-saving but also more efficient. At the same time, in order to prevent the reamer blade 2 from vibrating during operation and causing the rotating rod 31 to loosen and thus cause the reamer blade 2 to fall out, the arc spring 16 located between the support plate 15 and the limit plate 33 presses the limit plate 33 tightly under its own elastic force, effectively preventing the reamer blade 2 from falling out due to the loosening of the rotating rod 31, thereby greatly improving the safety of work. When the plug plate 14 is inserted into the slot 13, the plug plate 14 drives the plug block 142 to be inserted between the two anti-dropping plates 42. During the insertion of the plug block 142, the first chamfer 1421 on the plug block 143 abuts against the second chamfer 421 on the anti-dropping plate 42. With the insertion of the plug block 142, the two anti-dropping plates 42 move to both sides of the anti-dropping frame 41 respectively. The anti-dropping plates 42 squeeze the anti-dropping springs 43 during the movement. Under the action of the elastic force of the anti-dropping springs 43 themselves, the two anti-dropping plates 42 clamp the plug block 142 to prevent it from falling during the installation of the reamer blade 2, thereby preventing the reamer blade 2 from being damaged, thereby saving production costs.
