Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a wet grinding machine. Background Technology

[0002] A wet grinding wheel machine is a device that reduces dust by spraying water during the grinding process. Its main purpose is to spray water during grinding to prevent powder from scattering and protect the user's health. Since grinding wheels can become damaged and need replacement, existing grinding wheels are typically secured with nuts. This requires an external wrench to loosen the nuts and remove the wheel, increasing the inconvenience of disassembly. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that the existing technology uses nuts to tighten and fix the grinding wheel, which requires the use of an external workpiece wrench to turn the nuts and remove the grinding wheel, thus increasing the inconvenience of grinding wheel removal. Therefore, a wet grinding wheel machine is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a wet grinding machine, including a motor, a water tank fixedly connected to the lower end of the motor, a rotating shaft fixedly connected to the output shaft of the motor, an abutment plate fixedly connected to the rotating shaft, multiple limiting strips fixedly connected at equal intervals around the circumference of the rotating shaft, a grinding wheel sleeved on the rotating shaft, multiple limiting grooves equally spaced around the inner ring wall of the grinding wheel, multiple limiting strips slidably disposed in the limiting grooves, a through groove on the rotating shaft, an abutment block disposed in the through groove, the abutment block abutting against the grinding wheel, the abutment block being fixed by a fixing mechanism, and a spraying mechanism disposed on the water tank.

[0006] Preferably, the fixing mechanism includes a connecting ring, which is fixedly connected to the abutment block. A connecting post is provided inside the connecting ring, and a fixing ring is fixedly connected to the connecting post. A fixing lug is fixedly connected to the rotating shaft, and a spring is fixedly connected between the fixing lug and the fixing ring.

[0007] Preferably, a connecting rib is fixedly connected to the fixing ring, and the connecting rib passes through the fixing lug.

[0008] Preferably, the spraying mechanism includes a water pump, which is fixedly connected to the water tank. The water pump is connected to the water tank through a conduit, and a connecting pipe is provided on the water pump.

[0009] Preferably, a collection box is fixedly connected to the water tank.

[0010] Preferably, the collection box is equipped with a filter screen, and the collection box is connected to the water tank through a drain pipe.

[0011] Preferably, a protective cover is fixedly connected to the motor.

[0012] The present invention proposes a wet grinding machine with the following advantages: when disassembly is required, the abutment block can be removed from the through groove to release the limiting position on the grinding wheel, thereby allowing the grinding wheel to be removed and replaced. The operation is convenient and quick, without the need for external tools. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1: Refer to Figure 1-4A wet grinding wheel machine includes a motor 1, a protective cover 2 fixedly connected to the motor 1, a water tank 8 fixedly connected to the lower end of the motor 1, a rotating shaft 10 fixedly connected to the output shaft of the motor 1, an abutment plate 11 fixedly connected to the rotating shaft 10, multiple limiting strips 12 fixedly connected at equal intervals around the circumference of the rotating shaft 10, a grinding wheel 9 sleeved on the rotating shaft 10, multiple limiting grooves evenly spaced around the inner ring wall of the grinding wheel 9, the multiple limiting strips 12 slidably disposed in the limiting grooves, a through groove on the rotating shaft 10, an abutment block 13 disposed in the through groove, the abutment block 13 abutting against the grinding wheel 9, and the abutment block 13... The water tank 8 is equipped with a spraying mechanism and is fixed by a fixing mechanism. The grinding wheel 9 and the rotating shaft 10 are connected by a limiting strip 12 and a limiting groove, so that the rotating shaft 10 and the grinding wheel 9 can rotate coaxially. Then, by the engagement of the abutment block 13 and the abutment plate 11, the grinding wheel 9 is limited, preventing the grinding wheel 9 from moving axially on the rotating shaft 10, thereby fixing the grinding wheel 9. When disassembly is required, the abutment block 13 is removed from the through groove, which releases the limitation on the grinding wheel 9, allowing the grinding wheel 9 to be removed and replaced. The operation is convenient and quick, without the need for external tools.

[0020] The spraying mechanism includes a water pump 7, which is fixedly connected to a water tank 8. The water pump 7 is connected to the water tank 8 through a conduit, and a connecting pipe 4 is provided on the water pump 7. Water is sprayed out from the connecting pipe 4 to prevent powder from being scattered during grinding.

[0021] Example 2: Refer to Figure 1-4 In another preferred embodiment of this utility model, based on embodiment 1, the fixing mechanism includes a connecting ring 14, which is fixedly connected to the abutment block 13. A connecting post 15 is provided inside the connecting ring 14, and a fixing ring 16 is fixedly connected to the connecting post 15. A fixing ear 19 is fixedly connected to the rotating shaft 10, and a spring 17 is fixedly connected between the fixing ear 19 and the fixing ring 16. A connecting rib 18 is fixedly connected to the fixing ring 16, and the connecting rib 18 passes through the fixing ear 19. By placing the connecting post 15 inside the connecting ring 14, the abutment block 13 is limited, preventing the abutment block 13 from moving, thereby ensuring that the abutment block 13 is always located in the through groove, thus ensuring the fixing effect on the grinding wheel 9.

[0022] During disassembly, by pulling the connecting rib 18, the fixing ring 16 will be moved, causing the spring 17 to be compressed, the connecting post 15 to disengage from the connecting ring 14, and then the abutment block 13 can be removed from the through groove to release the limit on the grinding wheel 9, thereby removing the grinding wheel 9 from the rotating shaft 10 for replacement.

[0023] Example 3: Reference Figure 1As another preferred embodiment of this utility model, based on embodiment 2, a collection box 3 is fixedly connected to the water tank 8, so that the water sprayed down can be collected and reused.

[0024] Example 4: Reference Figure 1 As another preferred embodiment of this utility model, based on embodiment 3, a filter screen 5 is provided in the collection box 3. The collection box 3 is connected to the water tank 8 through the drain pipe 6. By using the filter screen 5 to filter the dust, the filtered water can enter the water tank 8 through the drain pipe 6 for direct recycling. When the water level drops, water can be added to the collection box 3.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
