The tool clamping groove 202 is rotatably connected to the vertical support block 207 through the rotating wheel 203 and the upper transfer wheel 209. The vertical support block 207 is located below the rotating wheel 203 and is provided with a vertical limit assembly 210; the grinding assembly 1 includes a grinding motor 101, and the output end of the grinding motor 101 is fixedly connected to the grinding disc 102, and the bottom of the grinding motor 101 is rotatably connected to the sliding base 103; the clamping and positioning base assembly 3 includes a clamping sliding groove 301, and the top of the clamping sliding groove 301 is fixedly connected to a slide rail, the clamping sliding seat 201 is slidably installed with the slide rail, and both sides of the top of the clamping sliding groove 301 are fixedly connected to the leveling rod 302.

[0030] Among them, when it is necessary to grind the turning tool, first fix the tool to be ground 204 on the tool clamping groove 202, then rotate the grinding motor 101 to adjust the grinding disc 102 to a suitable angle, then the sliding clamping positioning component 2 reaches the position of the grinding disc 102, and then rotate the rotating clamping block 208 and the tool clamping groove 202 to make the tool to be ground 204 adapt to the position of the grinding disc 102, wherein the horizontal limit component 205 and the vertical limit component 210 respectively rotate the rotating clamping block 208 and the tool clamping groove 202 is rotationally limited, and the horizontal limit assembly 205 has the same structure as the vertical limit assembly 210. Start the grinding motor 101 to rotate the grinding disc 102. At this time, the grinding assembly 1 and the clamping positioning assembly 2 can be moved on the grinding table 4 and the clamping positioning base assembly 3 respectively by rotating the clamping sliding seat 201 and the rotating handle set behind the grinding table 4 to grind the tool 204 to be ground. The leveling rod 302 is used to help the rotating clamping block 208 to rotate quickly to an angle parallel to the clamping sliding groove 301.

[0031] Refer to the attached Figure 5 - Figure 7The vertical limiting assembly 210 includes a limiting circular wheel 211, and the vertical support block 207 is provided with an annular plug-in groove 2010 at a position corresponding to the limiting circular wheel 211. The limiting circular wheel 211 is buckled and connected with the annular plug-in groove 2010. A pulling handle 213 is fixedly connected to one side of the limiting circular wheel 211, and a rotating plug-in inner rod 216 is fixedly connected to the other side of the limiting circular wheel 211. The rotating plug-in outer tube 214 is sleeved on the end of the rotating plug-in inner rod 216 away from the limiting circular wheel 211. The rotating plug-in outer tube 214 is One end of the rotating plug-in inner rod 216 away from the lower driving wheel 2011 is fixedly connected, and an automatic limiting spring 215 is fixedly connected between the limiting circular wheel 211 and the lower driving wheel 2011; a fixed shaft is fixedly connected to the center position of the upper transfer wheel 209, and the fixed shaft extends to the outside of the vertical support block 207 and is fixedly connected to the rotating wheel 203. The lower driving wheel 2011 is rotatably connected to the vertical support block 207, and the end of the rotating plug-in outer tube 214 away from the limiting circular wheel 211 is fixedly connected to the lower driving wheel 2011.

[0032] According to the above structure, when the tool clamping groove 202 needs to be rotated, the handle 213 needs to be pulled to separate the limiting circular wheel 211 from the annular plug-in groove 2010. At this time, the automatic limiting spring 215 is compressed, and then the handle 213 is rotated to rotate the limiting circular wheel 211. The limiting circular wheel 211 drives the lower driving wheel 2011 to rotate by rotating the plug-in inner rod 216 and the plug-in outer tube 214, thereby driving the upper transfer wheel 209 and the rotating wheel 203 to rotate, so as to adjust the tool clamping groove 202. The purpose of holding the angle of the groove 202 is that when the adjustment is completed, you only need to stop pulling the handle 213. Under the action of the automatic limit spring 215, the limit wheel 211 returns to its original position and engages with the annular plug-in groove 2010, so that the tool clamping groove 202 can be limited, effectively preventing the situation of forgetting to limit the position; the outer surface of the rotating plug-in inner rod 216 is provided with a sliding groove, and the inner surface of the rotating plug-in outer tube 214 is provided with a sliding rail. The sliding groove and the sliding rail prevent the rotating plug-in inner rod 216 and the rotating plug-in outer tube 214 from rotating with each other.

[0033] Refer to the attached Figure 8 - Figure 9 A sliding disk 217 is slidingly installed inside the limiting wheel 211, and a support ring 218 is provided on one side of the sliding disk 217. A connecting rod is fixedly connected between the sliding disk 217 and the support ring 218. The connecting rod is slidingly connected to the limiting wheel 211. A spring is fixedly connected between the sliding disk 217 and the limiting wheel 211. A pressing rod 212 is fixedly connected to the other side of the sliding disk 217. The pressing rod 212 passes through the inside of the pulling handle 213 and is slidingly connected to the pulling handle 213.

[0034] According to the above structure, when the tool clamping groove 202 needs to be precisely calibrated in angle, the sliding disk 217 inside the limiting circular wheel 211 can be pushed by pressing the pressing rod 212 and pulling up the pulling handle 213 to move the support ring 218 and contact the inner wall of the annular plug-in groove 2010. In this way, the support ring 218 forms a fulcrum, which converts the original pulling force rotation of the pulling handle 213 into grip rotation, making the adjustment of the rotating pulling handle 213 smoother and more convenient; the outer surfaces of the rotating wheel 203 and the rotating clamping block 208 are provided with a scale for facilitating angle adjustment.

[0035] The working principle of the present invention is as follows: when the tool holding slot 202 needs to be rotated, the handle 213 needs to be pulled to separate the limiting wheel 211 from the annular plug-in slot 2010. At this time, the automatic limiting spring 215 is compressed, and then the handle 213 is rotated to rotate the limiting wheel 211. The limiting wheel 211 drives the lower driving wheel 2011 to rotate by rotating the plug-in inner rod 216 and the plug-in outer tube 214, thereby driving the upper transfer wheel 209 and the rotating wheel 203 to rotate, so as to achieve the purpose of adjusting the angle of the tool holding slot 202. When the tool holding slot 202 needs to be accurately calibrated at an angle, When the tool is in the working state, the tool holder 202 can be adjusted by pressing the pressing rod 212 and pulling up the pulling handle 213. The sliding disk 217 inside the limiting circular wheel 211 moves so that the support ring 218 contacts the inner wall of the annular plug-in groove 2010. In this way, the support ring 218 forms a fulcrum, which converts the pulling force rotation of the pulling handle 213 into the gripping force rotation, making the adjustment and rotation of the pulling handle 213 smoother and more convenient. When the adjustment is completed, it is only necessary to stop pulling the handle 213. Under the action of the automatic limiting spring 215, the limiting circular wheel 211 returns to its original position and engages with the annular plug-in groove 2010, thereby limiting the tool holding groove 202.

[0036] Start the grinding motor 101 to rotate the grinding disc 102. At this time, the grinding assembly 1 and the clamping positioning assembly 2 can be moved on the grinding table 4 and the clamping positioning base assembly 3 respectively by rotating the clamping sliding seat 201 and the grinding table 4 to grind the tool 204 to be ground.

[0037] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
