DETAILED DESCRIPTION

The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

As shown in FIG1 , a clamping device for tool grinding includes: a workbench 1, and a clamping mechanism 5 and a grinding mechanism arranged on the workbench 1;

As shown in FIG2 , a rotating mechanism is provided inside the workbench 1, and the rotating mechanism includes: a motor 2 arranged on the inner bottom wall of the workbench 1, a sun gear 3 arranged at the output end of the motor 2, a ring gear 101 arranged on the inner side wall of the workbench 1, and a plurality of planetary gears 4 meshingly arranged between the sun gear 3 and the ring gear 101;

As shown in FIG. 3 , a support column 301 is fixedly connected to the top of the sun gear 3 , a rotating column 401 is fixedly connected to the top of the planetary gear 4 , a clamping mechanism 5 is arranged on the top of the rotating column 401 , and a grinding mechanism is arranged on the top of the support column 301 .

It should be noted that the tool to be polished can be clamped and fixed by the set clamping mechanism 5, and the surface of the fixed tool can be polished by the set polishing mechanism. At the same time, the starting motor 2 can drive the sun gear 3 connected to its output end to rotate, and the sun gear 3 will drive the planetary gear 4 meshing with it to rotate along the ring gear 101. Therefore, the tool clamped and fixed on the top of the rotating column 401 will rotate along the outside of the polishing mechanism, thereby facilitating the automatic polishing of each surface of the tool in turn, thereby improving the uniformity of the tool polishing.

There are at least two groups of planetary gears 4, rotating columns 401 and clamping mechanisms 5; multiple groups of clamping mechanisms 5 can fix multiple tools, so that multiple tools can be polished at the same time, thereby improving the speed of tool polishing.

The diameter of the sun gear 3 and the planetary gear 4 is the same; the rotation speed of the sun gear 3 and the planetary gear 4 is the same, thereby being able to improve the uniformity of the tool grinding by the grinding mechanism.

As shown in Figures 2 and 4, the clamping mechanism 5 includes: a fixed cylinder 501 arranged at the top of the rotating column 401, a chuck 502 arranged at the top of the fixed cylinder 501, and an extrusion screw sleeve 503 threadedly arranged between the fixed cylinder 501 and the chuck 502; the chuck (502) is provided with a conical surface whose outer diameter gradually decreases toward the fixed cylinder 501, the chuck (502) is provided with a fixed clamping groove connected to the fixed cylinder 501, and the side wall of the chuck (502) is provided with a plurality of notches distributed at equal distances and connected to the clamping groove.

It should be noted that, when the tool is inserted into the chuck 502 and the fixed cylinder 501, and then the extrusion screw sleeve 503 is rotated and screwed upward, the extrusion screw sleeve 503 will squeeze the conical surface on the outside of the chuck 502, so that the notch on the side wall of the chuck 502 is closed, and the tool can be clamped and fixed. When the tool is polished, the extrusion screw sleeve 503 is reversed and moved downward to separate from the chuck 502. At this time, the notch on the side wall of the chuck 502 will open, so that the tool can be loosened again.

The inner wall of the fixed cylinder 501 is slidably connected with a spring block 6, and a spring 601 is fixedly connected between the bottom of the spring block 6 and the inner bottom wall of the fixed cylinder 501; when the tool is inserted into the chuck 502 and the fixed cylinder 501 to fix it, the tool will squeeze the spring block 6 to move downward and compress the spring 601, and when the tool is released, the spring 601 will be released from the force and drive the spring block 6 to bounce upward and reset, so that the tool can be instantly ejected from the chuck 502, thereby increasing the speed of tool disassembly.

As shown in FIG. 1 , the grinding mechanism includes: a cylinder 7 disposed on the top of a support column 301 , a piston rod 701 disposed at an output end of the cylinder 7 , and a grinding head 8 disposed on the top of the piston rod 701 .

It should be noted that when the sun gear 3 rotates, it can drive the grinding head 8 on the cylinder 7 to rotate, and the tool can be polished by the rotating grinding head 8. The height of the grinding head 8 can also be adjusted through the operation of the cylinder 7, which is convenient for grinding tools of different lengths. In the process of tool grinding, the grinding head 8 can also be driven by the cylinder 7 to move up and down, which is convenient for grinding various positions in the length direction of the tool.

As shown in Figure 5, the grinding head 8 includes: a fixed frame 801, a grinding disc 802 slidably arranged inside the two ends of the fixed frame 801, and bolts 803 threadedly arranged on both sides of the top of the fixed frame 801; the upper surface of the grinding disc 802 is provided with a positioning groove 8021 that matches the bolt 803.

It should be noted that by pulling out the grinding disc 802 to slide inside the fixed frame 801, the grinding diameter can be changed, so that the grinding disc 802 can contact the outer wall of the tool of different coarseness, thereby facilitating the grinding of tools of different coarseness. After the position of the grinding disc 802 is adjusted, the bolt 803 is rotated to pass through the fixed frame 801 and abut against the positioning groove 8021, so that the position of the grinding disc 802 can be fixed.

A threaded head is fixedly connected to the top of the piston rod 701, and a threaded groove matching the threaded head is provided at the bottom of the fixed frame 801; when the equipment is finished using, the grinding head 8 can be unscrewed and removed from the piston rod 701, thereby facilitating maintenance and replacement of the grinding head 8.

As shown in FIG. 1 , a shielding plate 10 is fixedly connected to the top of the support column 301 , the cylinder 7 is fixedly connected to the top of the shielding plate 10 , and a slide groove for rotating the rotating column 401 is formed between the shielding plate 10 and the upper surface of the workbench 1 .

The outer wall of the rotating column 401 is fixedly connected with a collecting plate 9 .

It should be noted that the shielding plate 10 can prevent the debris generated by tool grinding from falling into the workbench 1 and affecting the rotating mechanism, while the collecting tray 9 can collect and process the fallen debris.

When the utility model is used, the tool to be polished can be clamped and fixed by the clamping mechanism 5 provided. At the same time, the sun gear 3 can be driven to rotate by the starter motor 2. When the sun gear 3 rotates, the grinding head 8 on the cylinder 7 can be driven to rotate. The rotating grinding head 8 can grind the tool. The height of the grinding head 8 can be adjusted by the cylinder 7, which is convenient for grinding tools of different lengths. In the process of tool grinding, the grinding head 8 can be driven up and down by the cylinder 7, which is convenient for grinding various positions in the length direction of the tool. And when the sun gear 3 rotates, it will also drive the planetary gear 4 meshing with it to rotate along the gear ring 101, so the tool clamped and fixed on the top of the rotating column 401 will rotate on the outside of the grinding head 8, and then it is convenient to automatically grind each surface of the tool in sequence, so as to improve the uniformity of tool grinding. And multiple sets of clamping mechanisms 5 can fix multiple tools, so that multiple tools can be polished at the same time, and the speed of tool grinding can be improved.

The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model.
