Description

Technical Field

[0001] This utility model relates to the field of floor grinding machine technology, specifically a grinding disc replacement device for a floor grinding and polishing machine. Background Technology

[0002] Floor grinders are mainly used for grinding and treating floors. They can effectively grind terrazzo, concrete surfaces, epoxy mortar layers, and old epoxy floors. Floor polishers are used for grinding and polishing the surfaces and undersides of marble, tiles, etc. They are characterized by being lightweight, flexible, and highly efficient.

[0003] Existing patent CN217019934U discloses a grinding disc conversion device for a floor grinding and polishing machine, comprising a first housing, a second housing, and a grinding disc. The second housing is mounted on the top of the first housing, and the bottom of the second housing is movably connected to the first housing. A drive motor is mounted in the middle of the top of the second housing, and the bottom of the drive motor is fixedly connected to the second housing around its perimeter. A control switch is mounted on one side of the second housing and is movably connected to the second housing. A rotating block is mounted on the bottom of the first housing. This device has a simple structure and is easy to operate.

[0004] However, the grinding disc replacement device of this floor grinding and polishing machine still has some defects. When using it, the rotating block, base plate and grinding disc need to be disassembled as a whole before the grinding disc can be replaced, which makes the operation more cumbersome. Most existing floor grinding and polishing machine grinding discs use magnetic adsorption or Velcro attachment, so they can be removed directly when they need to be replaced. However, when replacing the grinding discs of the floor grinding and polishing machine, the floor grinding disc will cause the temperature to rise after use, so the grinding disc needs to be replaced by the replacement device.

[0005] Based on this, a grinding disc replacement device for a floor grinding and polishing machine is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-4 As shown, a grinding disc replacement device for a floor grinding and polishing machine includes an electric four-jaw chuck 1, which has four clamping jaws 11 inside. A support column 12 is installed on one side of the electric four-jaw chuck 1, a control switch 13 is installed on one side of the support column 12, and a battery 14 is installed at the bottom of the support column 12.

[0029] The electric four-jaw chuck 1 is equipped with four disengagement components around its perimeter;

[0030] A clamping assembly is mounted on the top of the clamping claw 11.

[0031] In this embodiment, the operation of the electric four-jaw chuck 1 drives the four clamping jaws 11 to move from the periphery to the center, thereby moving the clamping assembly to clamp and fix the grinding disc around its periphery. The operation of the disengagement assembly pushes the grinding disc away from the floor grinder, thus facilitating the disassembly and replacement of the grinding disc.

[0032] In one embodiment, such as Figure 1 and Figure 3As shown, the detachment assembly includes a support ring 2, which is installed around the electric four-jaw chuck 1. An electric push rod 21 is installed inside the support ring 2, and a pushing block 22 is installed on the top of the electric push rod 21. An anti-slip block 23 is installed on the top of the pushing block 22. The support ring 2 supports the electric push rod 21. The operation of the electric push rod 21 drives the pushing block 22 to move upward, thereby pushing it against the floor grinder through the anti-slip block 23, so that the grinding disc and the floor grinder are separated, which facilitates the disassembly of the grinding disc.

[0033] In one embodiment, such as Figure 1 and Figure 3 As shown, the support ring 2 is annular, and the anti-slip block 23 is made of natural rubber. The natural rubber material of the anti-slip block 23 provides a certain buffering effect and improves the fit.

[0034] In one embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the clamping assembly includes a support plate 3, which is installed on the top side of the clamping claw 11. A silicone plate 31 is installed on one side of the support plate 3, and a clamping plate 32 is installed on one side of the silicone plate 31. A support frame 33 is installed on the outer side of the support plate 3. The silicone plate 31 supports the clamping plate 32, thereby giving the clamping plate 32 a certain buffering effect. The support frame 33 wraps the outer layer of the clamping plate 32, preventing the clamping plate 32 from shifting.

[0035] In one embodiment, such as Figure 1 and Figure 4 As shown, the clamping plate 32 is serrated, and the silicone plate 31 is made of silicone rubber. The serrated shape of the clamping plate 32 and the silicone rubber material of the silicone plate 31 improve the clamping effect on the grinding disc.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, the electric four-jaw chuck 1 has an adsorption component installed in the middle for adsorption, which strengthens the connection between the chuck and the grinding disc.

[0037] In one embodiment, such as Figure 1 and Figure 2 As shown, the adsorption assembly consists of an electromagnet 15. The operation of the electromagnet 15 adsorbs the grinding disc, thereby assisting the clamping assembly in disassembling the grinding disc.

[0038] In one embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, the storage battery 14 is electrically connected to the electric four-jaw chuck 1, the electric push rod 21 and the electromagnet 15 through a parallel circuit, and is equipped with a control switch 13 to control the on and off of each circuit. The storage battery 14 provides power to the electric four-jaw chuck 1, the electric push rod 21 and the electromagnet 15, and the control switch 13 facilitates the control of the operation of each device.

[0039] The above embodiment discloses a grinding disc replacement device for a floor grinding and polishing machine. An electromagnet 15 attracts the grinding disc to be removed. The operation of an electric four-jaw chuck 1 moves four clamping jaws 11 simultaneously towards the center, thereby moving four support plates 3 towards the center. The clamping plates 32 clamp and fix the grinding disc around its perimeter. The serrated shape of the clamping plates 32 and the silicone rubber material of the silicone plates 31 improve the clamping effect on the grinding disc, preventing loosening and detachment during replacement, thus improving the practicality of the device. The support frame 33 further enhances the clamping effect. Plate 32 provides guidance and support, preventing the support frame 33 from shifting. When the grinding disc is too firmly fixed and difficult to disassemble, the operation of the electric push rod 21 inside the support ring 2 drives the push block 22 to move, so that the anti-slip block 23 fits against one side of the floor grinder, achieving an anti-slip effect. At the same time, it pushes the clamped grinding disc to detach from the floor grinder, making it easier to disassemble the grinding disc and improving the convenience of the device. The battery 14 provides power to the electric four-jaw chuck 1, electric push rod 21 and electromagnet 15. The control switch 13 facilitates the control of the operation of each device.

[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
