Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for producing rubber valve seats. Background Art

[0002] The rubber valve seat is a material used to regulate the flow of liquid or gas, usually used inside the valve. The main structure of the valve seat is divided into a base and a sealing gasket. The rubber valve seat is tightly fitted with the valve piston or valve seat surface through the sealing gasket, thereby realizing the sealing function of the valve. Therefore, during the processing and production of the rubber valve seat, it needs to be polished to ensure the quality of the product.

[0003] According to a Chinese patent document with announcement number CN217344926U, a grinding device for rubber valve seat production is disclosed, which includes a support plate, a fixed frame is fixedly connected to the top of the support plate, cavities are opened on both sides of the fixed frame, a spring is fixedly connected to the inner wall of the cavity, a column is fixedly connected to the top of the spring, and a grinding box is fixedly connected to the top of the column. The utility model has the following advantages and effects: when the staff presses the grinding box, the spring is compressed, thereby driving the grinding box to descend, and the grinding wheel will contact the rubber valve seat, so that the rubber valve seat can be polished. During the grinding process, the staff turns the hand wheel, so that the hand wheel drives the connecting rod to rotate, so that when the staff needs to change the grinding position of the rubber valve seat, the connecting rod can be turned to adjust the position of the rubber valve seat, which greatly improves the efficiency of grinding.

[0004] Based on the search of the above patents and in combination with the grinding devices in the prior art, it is found that when the above device is in use, the staff presses the grinding box to move the grinding wheel downward, and moves with the grinding wheel to achieve contact with the rubber valve seat, and cooperates with the staff to turn the handwheel to grind the rubber valve seat. However, in actual use, since the grinding wheel needs the staff to press the grinding box to drop, the pressure cannot accurately control the degree of the grinding wheel's descent, and the speed of rotation cannot be guaranteed during the rotation of the handwheel. Therefore, during the grinding process, the descent of the grinding wheel cannot be accurately controlled, and the rotation speed of the handwheel is not easy, which can easily cause uneven grinding during the grinding of the rubber valve seat, affecting the product quality, and it needs to be repeatedly polished and trimmed. The staff will consume physical energy if they press the grinding box for a long time, which will further affect the accuracy of the grinding wheel, thereby reducing practicality.
