Description
Technical Field
[0001] This utility model relates to the field of electric machining equipment, specifically a grinding wheel positioning device for a polishing apparatus. Background Technology
[0002] Polishing machines, also known as grinding machines, are often used for mechanical grinding, polishing, and waxing. They remove surface imperfections and improve gloss or smoothness through mechanical friction or chemical action. Their core functions include repairing surface defects (such as scratches and sandpaper marks), removing burrs, and enhancing mirror effects. An electric motor drives a sponge or wool polishing disc mounted on the polishing machine to rotate at high speed. Due to the combined action of the polishing disc and polishing agent and their friction against the surface to be polished, the purpose of removing paint contamination, oxidation layers, and shallow scratches can be achieved.
[0003] However, existing polishing machines still have the following problems during use: Existing polishing machines use grinding wheels that rotate at excessive speeds. Under centrifugal force and vibration, the fasteners on the grinding wheels are prone to loosening, leading to inaccurate wheel positioning. This can cause abnormal vibration and noise in the equipment. Furthermore, an unpositioned grinding wheel will create dynamic imbalance at high speeds, causing the polishing wheel or workpiece to jump, affecting processing quality and potentially damaging the equipment structure. Therefore, a grinding wheel positioning device for polishing equipment is essential in the field of existing electric machining equipment. Utility Model Content
[0004] To address the shortcomings of existing technologies, such as inaccurate wheel positioning which can easily damage equipment, this utility model proposes a wheel positioning device for a polishing apparatus.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a grinding wheel positioning device for a polishing apparatus, comprising: A support platform is provided, on which a bearing seat is fixedly mounted. A rotating shaft is movably mounted on the bearing seat. An assembly plate is fixedly mounted on one end of the rotating shaft. Multiple threaded rods are fixedly mounted on the assembly plate. A grinding wheel body is inserted into each threaded rod. An installation plate is inserted into each threaded rod. The grinding wheel body is located between the installation plate and the assembly plate. An external threaded fixing plate is fixedly mounted on the installation plate. The external threaded fixing plate is inserted into the threaded rod. A nut is threaded onto each threaded rod. The nut is fitted to the surface of the external threaded fixing plate. The positioning mechanism is located on both sides of the external threaded fixing plate. The positioning mechanism includes an assembly block, which is fixedly assembled with the mounting plate. Each assembly block is provided with a slot, and each slot is fixedly fitted with a guide rod. A threaded positioning cover is threadedly assembled with an external threaded fixing disc. The surface of the threaded positioning cover is provided with a rotating groove, and a rotating ring is movably assembled on the rotating groove. Insert blocks are symmetrically fixed on the rotating ring, and each insert block is provided with a traction hole. The traction hole is movably assembled with a guide rod on the slot.
[0006] Preferably, each of the insert blocks has a traction arc surface on its end face and a locking hole on its end face, with the locking hole located on one side of the traction arc surface.
[0007] Preferably, each assembly block has an internal cavity, and each assembly block has a traction port on its side, which communicates with the internal cavity.
[0008] Preferably, each inner cavity is fixedly fitted with a telescopic spring, and one end of each telescopic spring is fixedly fitted with a traction disc.
[0009] Preferably, each of the traction discs is fixedly equipped with a toggle block, which is movably assembled with the traction port.
[0010] Preferably, each of the traction discs is fixedly equipped with a sector-shaped block, which moves through the slot and engages with the locking hole on the insert block.
[0011] Preferably, an operating motor is fixedly mounted on the support platform, and a drive gear is fixedly mounted on the output end of the operating motor.
[0012] Preferably, a driven gear is fixedly mounted on the rotating shaft, and the driven gear and the driving gear are toothed together.
[0013] The advantages of this utility model are: This invention uses a plug to move on a slot. The traction arc surface on the plug first contacts the sector block, causing the sector block to drive the traction disc to move in the inner cavity. The telescopic spring contracts until the sector block can engage with the locking hole on the plug, increasing the stability between the plug and the assembly block. The threaded positioning cover cannot move, making it easy for fasteners to not fall off and improving the positioning effect. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a grinding wheel positioning device for a polishing apparatus. (Refer to...) Figures 1-4A grinding wheel positioning device for a polishing apparatus includes a support platform 10, a bearing seat 13 fixedly mounted on the support platform 10, a rotating shaft 20 movably mounted on the bearing seat 13, an assembly plate 22 fixedly mounted at one end of the rotating shaft 20, a plurality of threaded rods 33 fixedly mounted on the assembly plate 22, a grinding wheel body 23 inserted into each threaded rod 33, and a mounting plate 31 inserted into each threaded rod 33. The grinding wheel body 23 is located between the mounting plate 31 and the assembly plate 22. An external threaded fixing plate 32 is fixedly mounted on the mounting plate 31, and the external threaded fixing plate 32 is inserted into the threaded rod 33. A nut 41 is threadedly mounted on each threaded rod 33, and the nut 41 fits against the surface of the external threaded fixing plate 32. A positioning mechanism 40 is symmetrically mounted on the mounting plate 31, and the positioning mechanism 40 is located at the external threaded fixing plate 32. On both sides of the threaded fixing plate 32, the positioning mechanism 40 includes an assembly block 4000, which is fixedly assembled with the mounting plate 31. Each assembly block 4000 is provided with a slot 4001, and each slot 4001 is fixedly assembled with a guide rod 4002. The threaded fixing plate 32 is threadedly assembled with a threaded positioning cover 30. The surface of the threaded positioning cover 30 is provided with a rotating groove 42, and a rotating ring 43 is movably assembled on the rotating groove 42. Insert blocks 50 are symmetrically fixedly assembled on the rotating ring 43. Each insert block 50 is provided with a traction hole 51, which is movably assembled with the guide rod 4002 on the slot 4001. Each end face of the insert block 50 is provided with a traction arc surface 52, and each end face of the insert block 50 is provided with a locking hole 53, which is located on one side of the traction arc surface 52.
[0019] In this invention, the grinding wheel body 23 is inserted into the threaded rod 33 of the assembly disc 22, and then the mounting disc 31 and the external threaded fixing disc 32 are respectively inserted into the threaded rod 33. A nut 41 is installed on the threaded rod 33, so that the grinding wheel body 23 is fixedly installed between the mounting disc 31 and the assembly disc 22. The insert block 50 of the threaded positioning cover 30 is inserted into the slot 4001, so that the traction hole 51 on the insert block 50 is inserted into the guide rod 4002 on the slot 4001. At this time, the threaded positioning cover 30 rotates and moves on the external threaded fixing disc 32, and the rotating groove 42 on the threaded positioning cover 30 rotates on the rotating ring 43, so that the traction hole 51 on the insert block 50 moves on the guide rod 4002.
[0020] Reference Figure 4 and Figure 5Each assembly block 4000 has an internal cavity 4005. Each side of the assembly block 4000 has a traction port 4003 that communicates with the internal cavity 4005. Each internal cavity 4005 is fixedly equipped with a telescopic spring 4006. Each end of the telescopic spring 4006 is fixedly equipped with a traction disc 4007. Each traction disc 4007 is fixedly equipped with a toggle block 4004 that moves in the traction port 4003. Each traction disc 4007 is fixedly equipped with a sector block 4008. The sector block 4008 moves through the slot 4001 and engages with the locking hole 53 on the insert block 50.
[0021] In this invention, the insert block 50 moves on the slot 4001. The traction arc surface 52 on the insert block 50 first contacts the sector block 4008, causing the sector block 4008 to drive the traction disc 4007 to move on the inner cavity 4005. The telescopic spring 4006 retracts until the sector block 4008 can engage with the locking hole 53 on the insert block 50, thereby increasing the stability between the insert block 50 and the assembly block 4000. The threaded positioning cover 30 cannot move, making it easy for the fasteners to not fall off and improving the positioning effect.
[0022] Reference Figure 1 and Figure 2 An operating motor 11 is fixedly mounted on the support platform 10. A drive gear 12 is fixedly mounted on the output end of the operating motor 11. A driven gear 21 that is toothed and meshed with the drive gear 12 is fixedly mounted on the rotating shaft 20.
[0023] In this utility model, the operating motor 11 is started, which causes the driving gear 12 to drive the driven gear 21 to rotate. The driven gear 21 drives the rotating shaft 20 to rotate on the bearing seat 13, which facilitates the polishing operation of the grinding wheel body 23 on the object during high-speed rotation.
[0024] Working principle: The grinding wheel body 23 is inserted into the threaded rod 33 of the assembly disc 22, and then the mounting disc 31 and the external threaded fixing disc 32 are respectively inserted into the threaded rod 33. Nut 41 is installed on the threaded rod 33, so that the grinding wheel body 23 is fixedly installed between the mounting disc 31 and the assembly disc 22. The insert block 50 of the threaded positioning cover 30 is inserted into the slot 4001, so that the traction hole 51 on the insert block 50 is inserted into the guide rod 4002 on the slot 4001. At this time, the threaded positioning cover 30 rotates and moves on the external threaded fixing disc 32, and the rotating groove 42 on the threaded positioning cover 30 rotates on the rotating ring 43, so that the traction hole 51 on the insert block 50 is inserted into the guide rod 4002. As the movement begins, the traction arc surface 52 on the insert block 50 first contacts the sector block 4008, causing the sector block 4008 to drive the traction disc 4007 to move on the inner cavity 4005. The telescopic spring 4006 contracts until the sector block 4008 can engage with the locking hole 53 on the insert block 50, increasing the stability between the insert block 50 and the assembly block 4000. The threaded positioning cover 30 cannot move, making it easy for fasteners to not fall off and improving the positioning effect. The operating motor 11 is started, causing the driving gear 12 to drive the driven gear 21 to rotate. The driven gear 21 drives the rotating shaft 20 to rotate on the bearing seat 13, facilitating the polishing operation of the grinding wheel body 23 on the object during high-speed rotation.
