Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding disc processing technology, and more specifically, it relates to an adjustable positioning fixture for grinding disc processing. Background Technology
[0002] Adjustable positioning fixtures for grinding discs are tools used to fix grinding discs and ensure machining accuracy. They can flexibly adjust the clamping position according to the size of the grinding disc and are widely used in metal processing, stone grinding and other fields. Traditional positioning fixtures have many problems: early fixtures were mostly fixed-size fixtures, and the fixture had to be changed when changing to different specifications of grinding discs, which was costly and time-consuming.
[0003] In existing technologies, traditional fixtures are only compatible with a single specification of grinding disc. When changing to different specifications of grinding discs, the entire fixture needs to be disassembled, resulting in low production efficiency. Traditional fixtures mostly use bolt fastening, which takes a long time to assemble and disassemble and requires tools, making them unsuitable for rapid model changeover requirements.

[0029] Please see Figures 1-5An adjustable positioning fixture for grinding disc processing includes a fixture body 1, a support plate 2, a support rod 3 circumferentially arranged on the support plate 2, an inclined block 4 on the support rod 3, a fixed shaft 5 fixedly arranged on the support plate 2, a clamping shaft 6 on one side of the fixed shaft 5, an installation device between the clamping shaft 6 and the fixed shaft 5, a clamping groove 7 on the clamping shaft 6, a clamping screw 8 threadedly connected to the clamping groove 7, a clamping plate 9 rotatably arranged at one end of the clamping screw 8, and a clamping handle 10 arranged at the other end. The installation device includes an installation rod. 11. The mounting rod 11 is set on the clamping shaft 6. The fixed shaft 5 is provided with a mounting groove 12 that mates with the mounting rod 11. The mounting rod 11 is circumferentially slidably provided with a snap-fit block 13. The mounting groove 12 is provided with a snap-fit ring groove 14 that mates with the snap-fit block 13. The clamping plate 9 is symmetrically provided with adjusting blocks 25. The adjusting blocks 25 are provided with an insertion rod 26. The clamping plate 9 is provided with an adjusting screw 27. The adjusting screw 27 is provided with symmetrical and opposite threads. The adjusting screw 27 is threadedly connected to the adjusting block 25. The tilting block 4 is provided with anti-slip texture 28.
[0030] In this embodiment, when installing the grinding disc, the existing grinding disc is usually provided with a central positioning hole and bolt mounting holes arranged around the central positioning hole. The grinding disc is placed against one side of the support plate 2, so that the four sides of the grinding disc abut against the inclined block 4. One end of the clamping shaft 6 is passed through the central positioning hole of the grinding disc and fixedly connected to the fixed shaft 5 through the mounting device. Then, the adjusting screw 27 is rotated, which drives the adjusting block 25 to move in opposite directions on the clamping plate 9, so that the insertion rod 26 is aligned with the bolt mounting hole. Then, the clamping screw 8 is rotated, and the clamping screw 8 rotates threadedly with the clamping shaft 6, causing the clamping plate 9 to move in the clamping groove 7. The clamping plate 9 is then pressed against the grinding disc on one side, and the insertion rod 26 is inserted into the bolt mounting hole, thereby installing the grinding disc on the support plate 2. The anti-slip texture 28 of the inclined block 4 improves the installation stability of the grinding disc. At the same time, this structure is compatible with grinding discs of different thicknesses, diameters, center positioning hole sizes, and bolt mounting hole positions, thus improving the installation stability of the grinding disc.
[0031] Please see Figures 3-5 As one embodiment of the installation device: the mounting rod 11 is provided with a snap-fit groove 15 in the circumference, the snap-fit block 13 is slidably disposed in the snap-fit groove 15, the snap-fit spring 16 is provided between the snap-fit groove 15 and the snap-fit block 13, the mounting rod 11 is provided with a positioning block 17, the mounting groove 12 is provided with a positioning groove 18 that cooperates with the positioning block 17, the snap-fit ring groove 14 is symmetrically provided with a reset groove 19, the reset groove 19 is provided with a reset block 20, the reset blocks 20 are connected to each other in the snap-fit ring groove 14 with a reset ring 21, the fixed shaft 5 is provided with a fixed plate 22, the reset block 20 is connected to a reset plate 23 on the outside of the fixed shaft 5, and a reset spring 24 is provided between the fixed plate 22 and the reset plate 23.
[0032] More specifically, when connecting the clamping shaft 6 and the fixed shaft 5, the mounting rod 11 is inserted into the mounting groove 12 of the fixed shaft 5. One side of the snap-fit block 13 is inclined. The mounting groove 12 presses the snap-fit block 13 into the snap-fit groove 15, while simultaneously pressing the snap-fit spring 16. When the positioning block 17 and the positioning groove 18 are aligned, the positioning block 17 extends into the positioning groove 18. After the snap-fit block 13 encounters the snap-fit ring groove 14, it extends out under the elastic force of the snap-fit spring 16, thereby connecting and fixing the fixed shaft 5 and the clamping shaft 6, which facilitates the fixing of the grinding disc. When disassembling the grinding disc, the clamping shaft 6 is first disassembled, and the reset plate 23 is moved towards the side of the fixed plate 22. The reset plate 23 moves in the reset groove 19 through the reset block 20, driving the reset ring 21 to move in the snap-fit ring groove 14. The reset ring 21 presses the snap-fit block 13 into the snap-fit groove 15 through the inclined surface of the snap-fit block 13, which facilitates the removal of the clamping shaft 6, and then the grinding disc is disassembled.
[0033] In summary, during the use or operation of the overall equipment: when installing the grinding disc, the existing grinding disc is usually provided with a central positioning hole and bolt mounting holes circumferentially located around the central positioning hole. The grinding disc is placed against one side of the support plate 2, so that the four sides of the grinding disc abut against the inclined block 4. One end of the clamping shaft 6 is passed through the central positioning hole of the grinding disc and fixedly connected to the fixed shaft 5 through the mounting device. Then, the adjusting screw 27 is rotated, which drives the adjusting block 25 to move in opposite directions on the clamping plate 9, so that the insertion rod 26 is engaged with the bolt. After aligning the holes, rotate the clamping screw 8. The clamping screw 8 and the clamping shaft 6 rotate threadedly, causing the clamping plate 9 to move within the clamping groove 7. The clamping plate 9 is then pressed against the grinding disc on one side, while the insertion rod 26 is inserted into the bolt mounting hole, thus mounting the grinding disc onto the support plate 2. The anti-slip texture 28 of the inclined block 4 improves the installation stability of the grinding disc. This structure is also compatible with grinding discs of different thicknesses, diameters, center positioning hole sizes, and bolt mounting hole positions, further enhancing the installation stability of the grinding disc.
[0034] When connecting the clamping shaft 6 and the fixed shaft 5, the mounting rod 11 is inserted into the mounting groove 12 of the fixed shaft 5. One side of the snap-fit block 13 is inclined. The mounting groove 12 presses the snap-fit block 13 into the snap-fit groove 15, while simultaneously pressing the snap-fit spring 16. When the positioning block 17 and the positioning groove 18 are aligned, the positioning block 17 extends into the positioning groove 18. After the snap-fit block 13 encounters the snap-fit ring groove 14, it extends out under the elastic force of the snap-fit spring 16, thereby connecting and fixing the fixed shaft 5 and the clamping shaft 6, which facilitates the fixing of the grinding disc. When disassembling the grinding disc, the clamping shaft 6 is first disassembled, and the reset plate 23 is moved to the side of the fixed plate 22. The reset plate 23 moves in the reset groove 19 through the reset block 20, driving the reset ring 21 to move in the snap-fit ring groove 14. The reset ring 21 presses the snap-fit block 13 into the snap-fit groove 15 through the inclined surface of the snap-fit block 13, which facilitates the removal of the clamping shaft 6, and then the grinding disc is disassembled.
