Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding wheel grinding component. Background Art

[0002] The grinding wheel assembly is a commonly used equipment in mechanical processing processes such as grinding and polishing. The grinding wheel will generate a lot of heat during high-speed rotation and grinding, which can easily cause deformation or thermal cracking of the workpiece, and will produce a large amount of grinding chips or dust. The flying of grinding chips into the air will affect the health of the operator. The existing technology uses cooling water spraying, which can not only increase the heat dissipation efficiency of the grinding wheel, but also mix the flying grinding chips with water mist to settle the grinding chips and prevent the grinding chips from diffusing into the surrounding air. However, long-term spraying work will cause a large amount of water mist to float and aggregate on the ground near the grinding wheel assembly, forming a pool of water, causing the working environment to be slippery, increasing the risk of the operator falling, and the sewage mixed with grinding chips settled on the ground and is not easy to clean. Utility Model Content

[0018] like Figure 1-Figure 2 As shown, the grinding wheel grinding assembly of the present scheme includes a water tank 7 with an opening at the upper end, and a support plate 6 is arranged at the upper end of the water tank 7; a protective cover 4 is fixedly connected to the support plate 6, and a grinding wheel 1 and a motor 3 for driving the grinding wheel 1 to rotate are arranged inside the protective cover 4; a water outlet is opened on one side of the water tank 7, and a pipe 8 with its free end extending into the protective cover 4 is fixedly connected to the water outlet, and a water pump 9 is arranged on the pipe 8; the free end of the pipe 8 is fixedly connected to a spray head 12, and the spray head 12 is located on one side of the grinding wheel 1; an opening 15 is opened on the side of the protective cover 4 opposite to the plane of the grinding wheel 1, and a plurality of flexible baffles 16 that are evenly laid and completely cover the opening 15 are arranged at the opening 15, and the baffles 16 are transparent.

[0019] A pipe 8 and a spray head 12 are provided on one side of the grinding wheel 1 to spray toward the grinding wheel 1. The sprayed cooling water can assist the grinding wheel 1 in cooling down, and the water mist can wrap the grinding chips to prevent them from diffusing into the air. The protective cover 4 outside the grinding wheel 1 can block most of the water mist to prevent it from drifting into the surrounding environment, and the baffle 16 can further isolate most of the water mist from drifting into the surrounding environment while ensuring that the workpiece to be ground can extend into the protective cover 4 and contact the grinding wheel 1. Most of the water mist is blocked inside the protective cover 4. Even if a small amount of water mist splashes out, it can evaporate and dry faster due to the small amount of water, and will not form water accumulation.

[0020] When grinding is needed, the flexible baffle 16 can be gently pushed aside to leave a gap for the workpiece to be grinded to extend into. The flexible baffle 16 can freely adjust the size of the entrance, can freely match the workpieces to be grinded of different sizes, and minimize the gap between the grinding object and the grinding object, and prevent the water mist from spraying out of the protective cover 4 to the greatest extent. The transparent baffle 16 can facilitate the operator to observe the position of the workpiece to be grinded and the contact with the grinding wheel 1.

[0021] The support plate 6 completely covers the opening of the water tank 7; the support plate 6 is provided with a plurality of through slots connected to the water tank 7, and the through slots are provided with a filter screen 5. The sprayed water can re-enter the water tank 7 through the filter screen 5, and the grinding debris is intercepted by the filter screen 5, so as to realize the recycling of water, save water resources, and facilitate the separation of water and grinding debris.

[0022] refer to Figure 1 The grinding wheel grinding assembly also includes a housing 17, which is arranged above the support plate 6; an adjusting shaft 18 axially penetrating the housing 17 is arranged inside the housing 17, one end of the adjusting shaft 18 extends out of the housing 17 and is vertically fixedly connected to the rotating shaft housing 19 of the grinding wheel 1, and the other end of the adjusting shaft 18 is connected to the driving mechanism; the grinding wheel 1 is rotatably connected to the housing 17 through the adjusting shaft 18. The driving mechanism can drive the adjusting shaft 18 to rotate, so that the grinding wheel 1 changes the grinding angle, thereby affecting the distribution of the grinding force and the grinding effect of the workpiece, so that the grinding wheel grinding assembly can adapt to more grinding application scenarios. The driving mechanism needs to have a locking function to prevent the adjusting shaft 18 from excessively rotating without control, resulting in safety accidents.

[0023] Specifically, a rotating plate 20 is mounted on the upper end of the casing 17, and the two ends of the rotating plate 20 are fixedly connected to the two ends of the adjusting shaft 18 respectively; the output shaft of the motor 3 is connected to the rotating shaft of the grinding wheel 1 through the synchronous belt 2. It is ensured that the grinding wheel 1 can still work normally while the angle is adjusted. The motor 3 drives the synchronous belt 2 to move, thereby driving the rotating shaft of the grinding wheel 1 to rotate, and then drives the grinding wheel 1 to rotate. The rotating plate 20 does not contact the casing 17, and the casing 17 does not block the rotation of the rotating plate 20. In addition, the rotation of the adjusting shaft 18 can simultaneously drive the rotating plate 20 and the rotating shaft housing 19 to rotate synchronously, and the deflection angle of the motor 3 is always consistent with the grinding wheel 1, thereby ensuring that the motor 3 drives the grinding wheel 1 to rotate around the rotating shaft while also rotating around the adjusting shaft 18.

[0024] A bottom plate 11 is arranged above the support plate 6, and a motor screw system 13 is fixedly connected to the bottom plate 11; a slider 14 is fixedly connected to the bottom of the housing 17, and the slider 14 is sleeved on the screw nut of the motor screw system 13 and is slidably connected to the screw. The housing 17 is slidably connected to the bottom plate 11 through the motor screw system 13, and the left and right positions of the housing 17 can be adjusted, thereby adjusting the lateral displacement of the grinding wheel 1, changing the position where the grinding wheel 1 contacts the workpiece, thereby affecting the grinding effect and adapting to more grinding application scenarios.

[0025] The bottom of the bottom plate 11 is fixedly connected to the support plate 6 through the support block 10, and a plurality of cavities are formed between the bottom plate 11 and the support block 10. The bottom plate 11 can be raised, and the formation of the cavity can prevent water from accumulating on the bottom plate 11 and assist in the discharge of cooling water. The through groove and the filter screen can be arranged at the lower position of the cavity to increase the area of the drainage channel.

[0026] As an embodiment of the utility model, the support block 10 is a strip-shaped rectangular block, on which a strip-shaped waist hole is opened; a bolt passing through the waist hole is arranged in the waist hole, and the end of the rod of the bolt passes through the upper surface of the base plate 11 and is tightened and fixed with a nut. The length of the support block 10 in the Z-axis direction is greater than the length of the base plate 11 in the Z-axis direction to increase the movable displacement length of the base plate 11. After loosening the nut, the base plate 11 can be pushed to move along the waist hole, thereby adjusting the position of the base plate 11 in the Z-axis direction, that is, the position of the grinding wheel 1 in the Z-axis direction. A support gasket is installed at the bottom of the support block 10, so that a certain space is left between the bottom surface of the support block 10 and the support plate 6, which is convenient for adjusting the installation position of the bolt.

[0027] In another embodiment, there are two support blocks 10, which are respectively arranged at the two ends of the bottom plate 11. One of them is a shorter cylindrical block or a square block, and the other is a strip-shaped arc block, which is provided with an arc-shaped waist hole, and the cylindrical block or the square block is rotatably connected to the bottom plate 11 through a rotating shaft. After the nut is loosened, one end of the bottom plate 11 can rotate around the rotating shaft, and the other end moves along the arc-shaped waist hole. Thereby achieving the purpose of adjusting the angle of the grinding wheel 1 in different directions.

[0028] In summary, the present solution can reduce the occurrence of slippery working environment and facilitate separation of abrasive chips from a mixture of water and abrasive chips, so as to further recycle the fixed abrasive chips.
