Description

Technical Field

[0001] This utility model relates to the field of flange processing, and in particular to a flange inner surface grinding device. Background Technology

[0002] A flange is a type of fitting that connects pipes, valves, equipment and other components. In industry, a flange is a disc-shaped part with a flange around the edge on a slightly circular main plate. There are usually holes on the flange, and two flanges can be connected by bolts to connect two sections of pipe or other objects. Polishing the inner surface of a flange refers to the process of treating the inner surface of the flange to achieve a certain smoothness or remove surface defects.

[0003] Existing methods for grinding the inner wall of flange sleeves typically involve placing the flange sleeve on a grinding machine and then rotating the grinding wheel on the machine to grind the flange sleeve. However, current grinding machines lack the function of collecting debris, making it difficult to collect the debris. During the grinding process, the debris generated will fall onto the grinding machine, which is not easy to process afterward and is quite inconvenient to use.

[0004] Therefore, it is necessary to design a flange inner surface grinding device that can adjust the position of the grinding wheel for grinding, making it easy to adapt to the grinding of flanges with different inner diameters, with high flexibility, and can collect debris and wastewater during grinding for easy collection and treatment. Utility Model Content

[0005] To overcome the shortcomings of current grinding equipment, which lacks the function of collecting debris and makes it difficult to collect debris, resulting in debris falling onto the grinding equipment during grinding and being difficult to process later, making it inconvenient to use, this utility model provides a flange inner surface grinding device that can adjust the position of the grinding wheel for grinding, making it easy to adapt to the grinding of flanges with different inner diameters. It is highly flexible and can collect debris and wastewater during grinding, facilitating the collection and treatment of debris and wastewater.

[0006] A flange inner surface grinding device includes a support frame, a connecting frame, a limiting component, a grinding component, and a collecting component. The connecting frame is connected to the upper front side of the support frame, multiple limiting components are snapped into the front of the support frame, the grinding component is provided on the upper part of the support frame, and the collecting component is placed on the lower part of the support frame.

[0007] To further explain, the grinding assembly includes a first motor, a turntable, a lead screw, a rodless cylinder, a second motor, and a grinding wheel. The first motor is connected to the connecting frame, the turntable is connected to the output shaft of the first motor, the lead screw is rotatably connected to the turntable, the rodless cylinder is threadedly connected to the lead screw, the rodless cylinder is slidably connected to the turntable, the second motor is connected to the slider of the rodless cylinder, and the grinding wheel is connected to the output shaft of the second motor.

[0008] To further explain, a handle is provided on the front side of the lead screw.

[0009] To further explain, the collection assembly includes a collection box and wheels. The collection box is placed on the ground and located under the support frame. The collection box is rotatably connected to two wheels on the left and right sides at both the front and rear.

[0010] To further explain, it also includes a water tank and an electric sprinkler head. The water tank is placed on the ground and is located on the outside of the support frame. The electric sprinkler head is snapped onto the top of the water tank.

[0011] To further clarify, the water tank is made of transparent material.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model moves the grinding wheel so that it contacts the inner wall of the flange sleeve. The inner side of the flange sleeve is ground by the rotation of the grinding wheel and the turntable. The debris and wastewater are collected by the collection box. The position of the grinding wheel can be adjusted for grinding, which is convenient for grinding flange sleeves with different inner diameters. It is highly flexible and can collect debris and wastewater during grinding, which is convenient for the collection and treatment of debris and wastewater. It is easy to use.

[0013] 2. During the grinding process, this utility model sprays water from the water tank through an electric nozzle, causing the water to fall onto the flange sleeve and grinding wheel. This sprays water onto the flange sleeve and grinding wheel during the grinding process, reducing the temperature, preventing the flange sleeve from overheating and deforming or being damaged, extending the service life of the grinding wheel, and improving the safety of use.

Detailed Implementation

[0018] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0019] A flange inner surface grinding device, such as Figures 1-3 As shown, the device includes a support frame 1, a connecting frame 2, a first motor 3, a turntable 4, a lead screw 5, a rodless cylinder 6, a second motor 7, a grinding wheel 8, a limiting component 9, a water tank 10, an electric nozzle 11, a collection box 12, and wheels 13. The connecting frame 2 is connected to the upper front of the support frame 1. The first motor 3 is connected to the connecting frame 2. The turntable 4 is connected to the output shaft of the first motor 3. The lead screw 5 is rotatably connected to the turntable 4. A handle is provided on the front of the lead screw 5 for easy gripping and rotation. A rodless cylinder 6 is threadedly connected to the lead screw 5. The rodless cylinder 6... The turntable 4 is connected in a sliding manner. The slider of the rodless cylinder 6 is connected to the second motor 7. The output shaft of the second motor 7 is connected to the grinding wheel 8. The front of the support frame 1 is clamped with eight limit pieces 9. The water storage tank 10 is placed on the ground. The water storage tank 10 is located on the outside of the support frame 1. The water storage tank 10 is made of transparent material, which makes it easy to observe the water usage inside. The upper part of the water storage tank 10 is clamped with an electric nozzle 11. The collection box 12 is placed on the ground. The collection box 12 is located at the lower part of the support frame 1. The front and rear parts of the collection box 12 are rotatably connected with two wheels 13.

[0020] When grinding the inner surface of the flange sleeve is required, this device can be used. The support frame 1 is brought into contact with the ground, water is added to the water tank 10, and the electric nozzle 11 is then engaged with the water tank 10. The water tank 10 is then placed on the left and right sides of the support frame 1. The collection box 12 is then pushed to the underside of the support frame 1, causing the wheel 13 to rotate. The flange sleeve is then placed on the support frame 1, and the limiting member 9 is engaged with the support frame 1 to limit and fix the flange sleeve. Next, the rodless cylinder 6 is activated, causing the slider on the rodless cylinder 6 to move, thereby driving the second motor 7 and the grinding wheel 8. After moving to the appropriate position, according to the inner diameter of the flange sleeve, the screw 5 is turned by the handle, causing the rodless cylinder 6 to move under the action of the thread, which in turn drives the second motor 7 and the grinding wheel 8 to move, so that the grinding wheel 8 contacts the inner wall of the flange sleeve. Then, the second motor 7 is started, driving the grinding wheel 8 to rotate. Next, the first motor 3 is started, driving the turntable 4 to rotate, causing the screw 5, rodless cylinder 6, second motor 7, and grinding wheel 8 to rotate, thereby grinding the inner side of the flange sleeve. During the grinding process, the electric spray head 11 is started, and the electric spray head 11... 1. Water is sprayed from the water tank 10, causing it to fall onto the flange sleeve and grinding wheel 8. The water tank 10 is made of transparent material, making it easy to observe the water usage inside. This allows water to be sprayed onto the flange sleeve and grinding wheel 8 during the grinding process, reducing the temperature and preventing the flange sleeve from overheating and deforming or being damaged. This also extends the service life of the grinding wheel 8 and improves safety. Grinding debris then falls into the collection tank 12, and excess water flows into the collection tank 12, collecting debris and wastewater. This allows for adjustment of the position of the grinding wheel 8 for grinding, facilitating the grinding of flange sleeves with different inner diameters. The grinding machine is highly flexible and can collect debris and wastewater during grinding, making it easy to collect and process. It is convenient to use. After grinding, turn off the first motor 3 and the second motor 7, and then start the rodless cylinder 6 to operate in reverse, causing the slider to move in the opposite direction, which in turn drives the second motor 7 and the grinding wheel 8 to move in the opposite direction, causing the grinding wheel 8 to disengage from the flange sleeve. Then turn off the rodless cylinder 6, and then remove the limit piece 9. After that, remove the ground flange sleeve, and then pull the collection box 12 to move, causing the wheel 13 to rotate. Then the debris and wastewater in the collection box 12 can be processed.
