[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 7As shown, a flywheel processing positioning device according to an embodiment of the present invention includes a base frame 1; a fixing plate 12 is fixedly connected to the top of the base frame 1; multiple racks 13 are slidably connected to the middle of the fixing plate 12; a bearing plate 14 is installed on the top of the base frame 1; multiple sliders 15 are installed in the middle of the bearing plate 14; a second threaded groove 6 is opened in the middle of the racks 13; a third bolt 61 is installed in the middle of the sliders 15; a worm gear 16 is installed at the bottom of the fixing plate 12; a worm 17 is rotatably connected to the middle of the base frame 1; a gear ring 18 is fixedly connected to the middle of the worm gear 16; multiple gear transmission mechanisms are installed in the middle of the fixing plate 12; the gear transmission mechanisms include a first gear 31 and a second gear 32; the first gear 31 and the second gear 32 mesh with the gear ring 18 and the racks 13 respectively; during operation, the flywheel is... The disc-shaped workpiece to be processed is placed on the support plate 14 near the center. Then, the worm gear 17 is rotated, and the gear ring 18 is rotated through the cooperation of the worm gear 17 and the worm wheel 16. As the gear ring 18 rotates, the first gear 31 and the second gear 32 rotate, which in turn drives multiple racks 13 to slide towards the center at the same time. This causes multiple sliders 15 to move closer to each other and squeeze the workpiece in the center. Finally, the workpiece is squeezed in the center by the multiple sliders 15 and centered. The gear ring 18 is locked and cannot rotate, thus achieving stable clamping of the workpiece. With the above structure, the centering and positioning of the disc-shaped workpiece can be automatically completed when fixing it, and it can automatically lock so that the workpiece is difficult to move during processing, thereby improving the processing accuracy of the disc-shaped workpiece.

[0027] like Figures 1 to 6 As shown, a top rod 2 is slidably connected to the middle of the support plate 14; a fixed rod 21 is fixedly connected to the middle of the base frame 1; a rotating plate 22 is rotatably connected to the middle of the fixed rod 21; a fixed frame 23 is fixedly connected to the middle of the base frame 1; and a transmission rod 24 is slidably connected to the middle of the fixed frame 23. During operation, after the workpiece is processed, the worm gear 17 is rotated to move the multiple sliders 15 away from each other and stop clamping the workpiece. Then, one end of the rotating plate 22 is stepped on to raise the other end of the rotating plate 22, thereby lifting the transmission rod 24. As the transmission rod 24 rises, the top of the transmission rod 24 will abut against the bottom of the top rod 2 and lift the top rod 2. The top of the top rod 2 will lift the workpiece above, creating a gap between the edge of the workpiece and the support plate 14, so that a finger can be inserted to lift and remove the workpiece. Through the above structure, after the workpiece is processed, a gap can be created between the edge of the workpiece and the support plate 14, so that the workpiece can be removed from the support plate 14, thus improving the ease of use of the lifting device.

[0028] like Figures 1 to 5As shown, the gear transmission mechanism includes a fixed base 3; the fixed base 3 is fixedly connected to the middle of the fixed plate 12; a first gear 31 is rotatably connected to the middle of the fixed base 3; a slot 33 is provided in the middle of the first gear 31; a rod 34 is fixedly connected to the middle of the second gear 32; a first threaded groove 35 is provided in the middle of the rod 34; a first bolt 36 is provided in the middle of the first gear 31; by inserting the first gear 31 into the middle of the fixed base 3, then inserting the rod 34 into the slot 33 from below the first gear 31, and then screwing the first bolt 36 into the first threaded groove 35, the assembly of the fixed base 3, the first gear 31, and the second gear 32 is completed, and the gear ring 18 rotates. When the gear ring 18 meshes with the second gear 32, it drives the first gear 31 to rotate. Then, the meshing of the first gear 31 and the rack 13 drives the rack 13 to move. When the teeth of the first gear 31 or the second gear 32 are worn excessively due to long-term use, the first gear 31 and the second gear 32 can be removed and the worn parts replaced according to the reverse operation of the above installation steps. With the above structure, the first gear 31 and the second gear 32 can be easily replaced when they are worn, reducing the impact on the centering effect caused by the wear of the teeth of the first gear 31 and the second gear 32, which prevents multiple racks 13 from moving at the same time.

[0029] like Figures 1 to 6 As shown, a connecting groove 4 is provided in the middle of the fixed plate 12; a connecting block 41 is fixedly connected to the bottom of the rack 13; the connecting groove 4 and the connecting block 41 are shaped and non-circular; the top rod 2 passes through the connecting block 41; during operation, when installing the bearing plate 14, the bearing plate 14 can be quickly installed by simply inserting the connecting block 41 into the connecting groove 4, and then the rack 13 and the slider 15 are connected by the third bolt 61. When it is necessary to inspect and maintain some components below the bearing plate 14, the multiple third bolts 61 are unscrewed first, and then the bearing plate 14 is lifted and removed to expose the multiple racks 13 and other components below for inspection and maintenance. Through the above structure, the bearing plate 14 can be easily disassembled and assembled, so as to facilitate the maintenance and replacement of components such as the rack 13 located on the fixed plate 12, thereby improving the ease of use of the device.

[0030] like Figure 4 As shown, a first sleeve ring 5 is rotatably connected to the middle of the fixed plate 12; multiple second bolts 51 are threadedly connected to the middle of the first sleeve ring 5; the worm gear 16 is connected to the first sleeve ring 5 through the second bolts 51; when the toothed ring 18 is worn to a large extent due to long-term use, the multiple second bolts 51 can be unscrewed to separate the worm gear 16 and the first sleeve ring 5, thereby replacing the worm gear 16 and the toothed ring 18. Through the above structure, the toothed ring 18 with excessive wear can be easily replaced, further reducing the occurrence of reduced centering effect caused by excessive wear of components.

[0031] like Figure 7 As shown, a second ring 7 is rotatably connected to the middle of the slider 15; a rubber sleeve 71 is fixedly connected to the middle of the second ring 7; during operation, when centering disc-shaped workpieces of different sizes, the third bolt 61 can be unscrewed from one of the second threaded grooves 6, and then the slider 15 can be slid to another second threaded groove 6 and the third bolt 61 can be screwed in, thereby completing the position adjustment of the slider 15. Through the above structure, the positions of multiple sliders 15 on the rack 13 can be adjusted, thereby centering and clamping disc-shaped workpieces of different diameters within a wider range within the limited stroke of the rack 13, improving the ease of use of the device.

[0032] like Figure 7 As shown, multiple second threaded grooves 6 are provided on the rack 13; multiple second threaded grooves 6 are evenly distributed on the rack 13; through the above structure, when clamping and fixing the workpiece, the sliding friction on the workpiece surface can be transformed into rolling friction, thereby reducing the wear on the workpiece surface.

[0033] During operation, the disc-shaped workpiece to be processed is placed on the support plate 14 near the center. Then, the worm gear 17 is rotated, and the gear ring 18 rotates through the cooperation of the worm gear 17 and the worm wheel 16. As the gear ring 18 rotates, the first gear 31 and the second gear 32 rotate, which in turn drives multiple racks 13 to slide towards the center simultaneously. This causes multiple sliders 15 to move closer together and squeeze the workpiece in the center. Finally, the workpiece is squeezed in the center by the multiple sliders 15 and centered. The gear ring 18 is locked and cannot rotate due to the worm wheel 16 and the worm gear 17, thus achieving stable clamping of the workpiece. After processing the workpiece, the worm gear 17 is rotated to make the multiple sliders 15 move closer together. The workpiece is no longer clamped. Then, one end of the rotating plate 22 is stepped on, causing the other end of the plate to rise, thus lifting the transmission rod 24. As the transmission rod 24 rises, its top abuts against the bottom of the push rod 2, lifting the push rod 2. The top of the push rod 2 lifts the workpiece above, creating a gap between the edge of the workpiece and the support plate 14, allowing fingers to be inserted to lift and remove the workpiece. The first gear 31 is inserted into the middle of the fixed base 3, and then the insertion rod 34 is inserted into the slot 33 from below the first gear 31. Finally, the first bolt 36 is screwed into the first threaded groove 35, completing the assembly of the fixed base 3, the first gear 31, and the second gear 32. When the gear ring 18 rotates, it meshes with the second gear 32 and drives the first gear 31 to rotate. Then, the meshing of the first gear 31 and the rack 13 drives the rack 13 to move. When the teeth of the first gear 31 or the second gear 32 become excessively worn due to prolonged use, the installation steps described above can be reversed to remove the excessively worn parts and replace them. When installing the support plate 14, simply insert the connecting block 41 into the connecting groove 4 to quickly complete the installation of the support plate 14. Then, use the third bolt 61 to connect the rack 13 and the slider 15. When it is necessary to move the rack 13 below the support plate 14... When inspecting and maintaining some components, first unscrew multiple third bolts 61, then lift and remove the bearing plate 14 to expose multiple racks 13 and other components for inspection and maintenance. When the gear ring 18 is worn down due to long-term use, multiple second bolts 51 can be unscrewed to separate the worm gear 16 from the first ring 5, thereby replacing the worm gear 16 and the gear ring 18. When centering disc-shaped workpieces of different sizes, the third bolt 61 can be unscrewed from one second threaded groove 6, then the slider 15 can be slid to another second threaded groove 6 and the third bolt 61 can be screwed in to complete the position adjustment of the slider 15.
