[0002] The sword is a kind of handicraft with artistic appreciation value. It is forged with high-quality materials and unique casting methods. The existing swords are different from the traditional hand-forged swords. Most of them use the computer-guided machine to cut the steel plate into the rough outline of the sword body, and then put it on the grinding machine to grind the blade; Although the existing grinding method has a device that can fix the sword body and then grind the blade of the sword body, the grinding angle is fixed and cannot be automatically ground according to swords of different widths. Therefore, the angle and size of the sword blade that can be ground are also fixed. As shown in the figure, two swords of the same thickness but different sizes have different grinding areas (the shaded part is the grinding area). Figure 1-2 As shown, most of the time, the sword blank is polished manually on a polishing belt, and the four sword blades on the upper and lower surfaces are polished step by step. During the polishing process, the staff needs to rely on their experience to judge the polishing angle and polishing condition of each surface, so the sword blade needs to be picked up and measured many times, and the deviation cannot be too large, otherwise it will result in a defective product.

[0019] See also Figure 1-17 The present invention provides a technical solution: an adjustable dustproof sword manufacturing grinding device, comprising a base 1 and a grinding belt 2, a grinding group is arranged below the grinding belt 2, the grinding group is used to drive the grinding belt 2 to work, the grinding belt 2 is used to grind the blade part of the sword body, a support group is arranged above the base 1, the support group is used to fix the sword body, and adjust the grinding angle between the grinding belt 2 and the sword body according to the different sizes of the sword body, and a dustproof group is arranged on the base 1; The support group includes one or more bottom plates 3, each of which is slidably connected to two baffles 4, and a fourth spring 29 is fixedly connected between the two baffles 4 and the bottom plate 3. A connecting block 21 is provided on the two baffles 4, and the two baffles 4 are symmetrically arranged. A pressure plate 5 is slidably connected to the top of each bottom plate 3; a first spring 6 is fixedly connected between the pressure plate 5 and the baffle 4, and a first support rod 7 is rotatably connected to the side wall of the pressure plate 5. The two first support rods 7 are symmetrically arranged, and the two first support rods 7 are slidably connected to the second support rod 8. The bottom ends of the two second support rods 8 are rotatably connected to the two connecting blocks 21 respectively. A fixed rod 9 is provided on one side of the bottom plate 3, and the fixed rod 9 is located above the first support rod 7. One side of each bottom plate 3 is fixedly connected There is an indicator rod 10, which is located at the exact center between the top of the base plate 3 and the bottom of the baffle 4. After the first support rod 7 and the second support rod 8 are rotated upward to the maximum angle, they will fit with the bottom of the fixed rod 9. Each indicator rod 10 is rotatably connected to a vertical rod 12, and the fixed rod 9 is fixedly connected to the vertical rod 12. A rotation group is provided on one side of each vertical rod 12, and the rotation group is used to drive the base plate 3 to rotate upward around the rotation axis by a certain angle. The base plate 3 is provided with a slide groove 14, and a support plate 13 slides together inside the slide groove 14. An electric clamp 15 is provided on the support plate 13, and a driving group is provided below the electric clamp 15. The driving group supports the base plate 3 and the support plate 13, and can enable the base plate 3 to move axially along the base 1.

[0020] When the above scheme is put into practical use, the two bottom plates 3 can move straightly forward and backward along the axial direction of the base 1 under the action of the driving group, and can also support the support plate 13. Before working, the sword blank needs to be adjusted, and different areas to be polished are determined according to sword blanks of the same thickness but different sizes; The adjustment works as follows: Figure 3-12 As shown: First, the two bottom plates 3 are moved so that the distance between the two bottom plates 3 is greater than the length of the sword blank. Then, the two ends of the sword blank are respectively inserted between the two baffles 4. When the sword blank is inserted, the two baffles 4 will move away from each other along the two bottom plates 3 and stretch the fourth spring 29. At this time, the pressure plate 5 will also slide up along the bottom plates 3 and stretch the first spring 6. The four sides of the sword blank can be fixed and restricted respectively by the bottom plates 3, the pressure plate 5 and the two baffles 4, so that the sword blank will not deviate at an angle after insertion. When the two baffles 4 move away from each other, they will respectively drive the two connecting blocks 21 to move toward each other. When the two connecting blocks 21 move, they will pull the bottom end of the second support rod 8 to move, and with the movement of the connecting block 21, the distance between the bottom end of the second support rod 8 and the top end of the first support rod 7 will become farther and farther, and the rotation axis of the top end of the first support rod 7 is fixed at this position. During this process, the second support rod 8 will slide along the first support rod 7, and when the second support rod 8 slides, the top end of the first support rod 7 will rotate upward at a small angle around the rotation axis on the side wall of the pressure plate 5. Then, at this time, the angle between the top of the first support rod 7 and the horizontal plane of the top of the sword blank will become smaller, such as Figure 8 As shown, Figure 8 The area to be polished is the angle between the top of the first support rod 7 and the horizontal plane of the top of the sword blank, that is, the area of ​​the upper half of the sword blank that needs to be polished. The area to be polished in the lower half and the area to be polished in the upper half are symmetrically distributed about the center point of the upper end of the indicator rod 10. Conversely, if the distance between the top end of the first support rod 7 and the bottom end of the second support rod 8 is closer, it means that the angle between the top of the first support rod 7 and the horizontal plane of the top of the sword blank is larger. After the sword blank is directly inserted between the two baffles 4, the two baffles 4, the pressure plate 5 and the bottom plate 3 can complete the fixing and limiting work of the sword blank, so that the sword blank will not move, and according to the distance between the top rotation axis of the first support rod 7 and the bottom rotation axis of the second support rod 8, the angle between the top of the first support rod 7 and the horizontal plane of the top of the sword blank is changed, that is, the area to be polished is changed, and the angles required for polishing different sword blanks can be automatically calculated, and the results can be automatically and quickly displayed without the need for the polishing master to measure and mark, saving time and efficiency; At this point, the adjustment work has been completed, and subsequent preparation work before grinding is required. For grinding work, please refer to Figure 8-10 and Fig.13 , the preparation work before grinding is as follows: At this time, the rotating group starts to work. When the rotating group works, it will push up the second support rod 8 from below the rotation axis of the second support rod 8 away from the grinding belt 2. Because the bottom plate 3 is fixedly connected with the indicator rod 10, but the indicator rod 10 is rotationally connected with the vertical rod 12, and the indicator rod 10 has a large damping property, the bottom plate 3 is in a horizontal state through the damping property, so the rotation axis of the indicator rod 10 is the rotation center. When the second support rod 8 is pushed up, the bottom plate 3, the indicator rod 10, the baffle 4, the pressure plate 5 and the sword blank will rotate upward around the rotation axis, and the sword blank The thickness of the sword blank is fixed, and the upper end of the indicator rod 10 is at the center point of the sword blank, that is, the rotation axis of the indicator rod 10 is the rotation axis position of the bottom plate 3, the indicator rod 10, the baffle plate 4, the pressure plate 5 and the sword blank, but the bottom end of the fixed rod 9 is in the same horizontal plane as the top of the sword blank, and the fixed rod 9 is above the first support rod 7 and the second support rod 8, so when the first support rod 7 and the second support rod 8 rotate upward around the rotation axis, the limit position is to rotate to the position where the top of the first support rod 7 and the second support rod 8 is in contact with the bottom of the fixed rod 9, such as Fig.10 As shown, when the top of the first support rod 7 and the second support rod 8 are in contact with the bottom of the fixing rod 9, the rotation angle of the bottom plate 3 is Figure 8 After the rotation is completed, the bottom plate 3, the indicator rod 10, the baffle 4, the pressure plate 5 and the sword blank are all in a tilted state, so the angle of the bottom end of the sword blank compared to the initial position after the rotation is the area to be polished, such as Fig.13 As shown, the two points a on the figure are the areas to be polished; Because the support plate 13 is slidably connected with the slide groove 14 on the bottom plate 3, when the bottom plate 3 moves, the slide groove 14 will slide relative to the support plate 13, but when the bottom plate 3 rotates, the slide groove 14 will drive the support plate 13 to swing relative to a fixed angle, and the driving group will not limit the swing of the support plate 13 under the condition of supporting the support plate 13, that is, the support plate 13 always maintains a relative position with the sword blank. At this time, the electric clamp 15 is started to clamp the sword blank. When clamping the sword blank, the sword blank is restricted from four sides, so there will be no deviation. After the electric clamp 15 clamps the sword blank, the two bottom plates 3 are manually pushed to separate from the sword blank, and then the driving group will drive the vertical rod 12 and the support plate 13 to descend to the area to be polished on the polishing belt 2 for polishing, that is, Fig.13 Position on; Because four areas need to be polished, when one area is polished, the driving group drives the support plate 13 and the vertical rod 12 to rise to the initial position, and then the electric clamp 15 releases the clamping of the sword blank, and then the staff turns the sword blank over, but does not turn it, and then inserts it into the two bottom plates 3, and then repeats the adjustment work and the preparation work before polishing until the four areas are polished and replaced; When the sword blank is restricted from four sides, the sword blank is clamped by the electric clamp 15 and the rotating group drives the bottom plate 3 to rotate, so that the sword blank can be in a stable state without deviation, thereby avoiding the change of the grinding area caused by deviation, and the adjustment work before grinding and the preparation work before grinding for different grinding areas of the sword blank will not change the position, thereby improving the grinding accuracy and grinding efficiency, and one grinding belt 2 can grind two sword blanks; The dust prevention group can prevent the debris and dust generated during grinding from scattering.

[0021] As a further solution of the present invention, the rotating assembly includes a first cylinder 11 and a top plate 16, the top plate 16 is located below the first support rod 7 and the second support rod 8, the top plate 16 is used to lift the first support rod 7 and the second support rod 8, the first cylinder 11 is fixedly connected to the side wall of the vertical rod 12, a groove is provided on the vertical rod 12, the top plate 16 is slidably connected inside the groove, and a second spring 17 is fixedly connected between the end of the first cylinder 11 and the top of the top plate 16.

[0022] When the above-mentioned rotating group is working, the first cylinder 11 is started first, and the first cylinder 11 is supported by the vertical rod 12. After the first cylinder 11 is started, it will extend and drive the second spring 17 to extend through the connecting piece fixedly connected to the top of the first cylinder 11, so that the top plate 16 can slide upward along the notch on the vertical rod 12, thereby lifting the second support rod 8 from the bottom to make the bottom plate 3 and the sword blank rotate around the rotation axis of the indicator rod 10 until the top of the first support rod 7 and the second support rod 8 are in contact with the bottom of the fixed rod 9 and then stop. At this time, the first cylinder 11 continues to extend, but the second spring 17 will be stretched, so that the first support rod 7, the second support rod 8 and the fixed rod 9 remain in contact, and then the electric clamp 15 clamps the sword blank, and then the first cylinder 11 shortens until it is reset, and then the two bottom plates 3 are manually pushed to separate from the sword blank.

[0023] As a further solution of the present invention, the drive group includes a U-shaped frame 18, a guide groove 19 is opened on the U-shaped frame 18, the vertical rod 12 is slidably connected to the guide groove 19, the top of the U-shaped frame 18 is opened with an arc groove 20, the center point of the arc groove 20 and the center point of the indicator rod 10 are on the same axis, the ends of the support plate 13 are respectively slidably connected to the inside of the two arc grooves 20, the U-shaped frame 18 is slidably connected to two second cylinders 27, the bottom ends of the two second cylinders 27 are fixedly connected to the base 1, and a third spring 28 is fixedly connected between the ends of the two second cylinders 27 and the U-shaped frame 18.

[0024] When the above-mentioned driving group is working and performing adjustment work, the vertical rod 12 is supported by the U-shaped frame 18, and the two bottom plates 3 are manually pushed. The two bottom plates 3 will slide along the guide groove 19 through the two vertical rods 12, thereby completing the approach and distance between the bottom plate 3 and the end of the sword blank. The end of the support plate 13 is inside the arc groove 20. When the bottom plate 3 rotates around the rotation axis, it will drive the support plate 13 to slide along the arc groove 20. After the electric clamp 15 clamps the sword blank, the two bottom plates 3 are separated from the sword blank. Then the second cylinder 27 is shortened to drive the U-shaped frame 18 to drop to the limit position. When the second cylinder 27 drops to the limit position, the sword blank will contact the grinding belt 2. At this time, the third spring 28 will also be compressed to a certain extent. The third spring 28 can play a buffering role when the sword blank contacts the grinding belt 2. Then the grinding group drives the grinding belt 2 to grind the blade part of the sword blank. As the sword blank is polished, the third spring 28 will also gradually release its elasticity until the third spring 28 is completely released after the sword blank is polished.

[0025] As a further solution of the present invention, the two baffles 4, the bottom plate 3 and the pressure plate 5 are all provided with inclined surfaces.

[0028] When the above scheme is working, the position of the connecting block 21 is fixed and cannot meet the needs of fine-tuning. Therefore, the rotation of the screw 22 will drive the connecting block 21 to rise and fall along the baffle 4, thereby performing fine-tuning. A scale mark is provided on the baffle 4 to facilitate determination of the parameters during fine-tuning.

[0029] As a further solution of the present invention, the grinding group includes two rollers 23, and motors 24 are arranged inside the two rollers 23. The output shafts of the motors 24 are fixedly connected to the inner walls of the rollers 23, and the ends of the motors 24 are fixedly connected to the base 1.

[0030] When the grinding group is working, the motor 24 is fixedly connected to the base 1 to support the motor 24. After the motor 24 is started, it drives the roller 23 to rotate, thereby causing the grinding belt 2 to grind the sword blank.
