Description

Technical Field

[0001] This utility model relates to the field of polishing auxiliary equipment, specifically a grinding wheel calibration device for polishing equipment. Background Technology

[0002] When the grinding wheel of a polishing machine rotates at high speed, the severe vibration can cause the fasteners connecting the grinding wheel to loosen, leading to dynamic imbalance. An unbalanced grinding wheel causes severe vibration during high-speed operation, affecting not only equipment stability but also generating harsh noise and impacting the operating environment. Prolonged vibration accelerates the wear of the spindle bearings, and in severe cases, may cause spindle deformation or grinding wheel breakage, resulting in equipment damage or safety accidents. Grinding wheel eccentricity can cause vibration marks on the workpiece surface, reducing dimensional accuracy and affecting product quality. Continuous vibration increases mechanical load, reducing the overall lifespan of the grinding machine and requiring frequent maintenance or component replacement. Grinding wheel breakage or loosening can cause sparks to fly, resulting in personal injury. An unbalanced grinding wheel operating at high speed may even detach, leading to mechanical failure or personal injury. Therefore, the grinding wheel of a polishing machine needs to be checked and corrected by checking for loose fasteners during use.

[0003] However, the existing polishing equipment's grinding wheels still have the following problems during the calibration process: Existing severe vibrations can cause the fasteners connecting the grinding wheel to loosen. This loosening can lead to slight wheel tilting that is not visible to the naked eye, allowing the polishing process to continue and causing inconvenience to operators. Therefore, it is necessary to develop a grinding wheel calibration device for polishing equipment in the field of existing polishing auxiliary equipment. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the existing severe vibrations can cause the fasteners connecting the grinding wheel to loosen. The loosening of some fasteners can cause the grinding wheel to tilt slightly, which cannot be detected by the naked eye.

At this time, the positioning bolt 4009 is installed in the assembly hole 4014 and the corresponding mounting hole 4007, so that the position of the traction frame 4008 on the traction block 4003 is fixed.

[0024] Reference Figure 1 and Figure 2An operating motor 11 is fixedly mounted on the support frame 10. A drive gear 12 is fixedly mounted on the output end of the operating motor 11. A shaft 20 is movably mounted on the bearing frame 13. A driven gear 21 is fixedly mounted on the shaft 20. The driven gear 21 and the drive gear 12 are toothed together. A limit plate 22 is fixedly mounted on one end of the shaft 20. Multiple first threaded rods 31 are fixedly mounted on the limit plate 22. A second threaded rod 33 is fixedly mounted on the limit plate 22. The second threaded rod 33 is located between the multiple first threaded rods 31. A grinding wheel 23 is inserted into the multiple first threaded rods 31 and the second threaded rod 33. A roller 4108 is close to the grinding wheel 23. A positioning plate 30 is inserted into the multiple first threaded rods 31 and the second threaded rod 33. The positioning plate 30 is located on one side of the grinding wheel 23. A first nut 32 is threaded onto each of the first threaded rods 31. A second nut 42 is threaded onto each of the second threaded rods 33.

[0025] In this invention, the grinding wheel 23 is inserted into the first threaded rod 31 and the second threaded rod 33 of the limiting plate 22, and the positioning plate 30 is inserted into the first threaded rod 31 and the second threaded rod 33 of the limiting plate 22. A first nut 32 is installed on the first threaded rod 31 and a second nut 42 is installed on the second threaded rod 33, so that the grinding wheel 23 can be fixed with the limiting plate 22.

[0026] Working principle: The grinding wheel 23 is inserted into the first threaded rod 31 and the second threaded rod 33 of the limiting plate 22, and the positioning plate 30 is then inserted into the first threaded rod 31 and the second threaded rod 33 of the limiting plate 22. A first nut 32 is installed on the first threaded rod 31, and a second nut 42 is installed on the second threaded rod 33, thus fixing the grinding wheel 23 to the limiting plate 22. When the equipment is not running, the traction frame 4008 is on the guide rod 4006 via the sliding block 4013. The assembly hole 4014 is moved so that it coincides with the corresponding mounting hole 4007. At this time, positioning bolts 4009 are installed in the assembly hole 4014 and the corresponding mounting hole 4007, so that the position of the traction frame 4008 on the traction block 4003 is fixed. The roller 4108 is in contact with the surface of the grinding wheel 23. The adjusting bolt 4004 is rotated on the limit block 4001, so that the rotating rod 4011 drives the rotating disk 4012 to rotate on the rotating cavity 4010, so that the adjusting block 4008... 002 moves on the two extension rods 4000, the surface of the grinding wheel 23 moves, and the roller 4108 is subjected to force according to the inclination of the grinding wheel 23. The traction rod 4103 moves on the connecting block 4100, the fixed plate 4104 drives the telescopic spring 4105 to retract, and the traction rod 4103 drives the marker pen 4110 on the internal thread cover 4109 to move towards the movable opening 4115. The marker pen 4110 can mark the paper 4117. When the guide distance of the roller 4108 is too long, the indicator block 4113 drives one end of the operating rod 4112 to move inside the mounting tube 4111, and the spring spring 4114 contracts. Observe whether the paper 4117 is marked by the marker pen 4110. When the paper 4117 is marked, adjust the tightness of the first nut 32 on the first threaded rod 31 and the second nut 42 on the second threaded rod 33 so that the grinding wheel 23 can be corrected and the operation effect can be improved.
