Description

Technical Field

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. The grinder uses a grinding wheel as the main cutting tool and is used to finish metal and non-metal workpieces. It helps to achieve high surface quality and dimensional accuracy, so it is widely used in the field of precision machining in industrial production.

[0003] The sealing pair of the eccentric butterfly valve refers to the key component used to achieve the sealing function in the valve, which is usually composed of a valve seat and a valve plate (or a sealing ring). In the manufacturing process of the eccentric butterfly valve, the processing accuracy of the sealing pair directly affects the sealing performance of the eccentric butterfly valve. In order to ensure the flatness, roughness and dimensional accuracy of the sealing pair to achieve a good sealing effect, the sealing pair of the eccentric butterfly valve is generally precisely ground by using a high-precision grinder. The special positioning bevel plate manufactured by manufacturing the valve seat or valve plate according to the requirements is installed in the high-precision grinder, and the valve seat or valve plate is clamped and fixed by the bevel plate and the clamping tool and rotated. During the rotation, the valve seat or valve plate is finely processed by the grinding head in the high-precision grinder, so as to accurately grind the sealing pair of the eccentric butterfly valve.

[0110] The initial specification information of the eccentric butterfly valve refers to the initial specification information selected when the specification of the eccentric butterfly valve is selected. The initial specification information of the eccentric butterfly valve is obtained by querying from a database storing the corresponding relationship between the pressure detection value and the initial specification information of the eccentric butterfly valve, and the database is obtained after the operator pre-enters. The initial specification information of the eccentric butterfly valve is determined by querying the pressure detection value, which is convenient for subsequent use.

[0136] The abnormal number value refers to the number value corresponding to the distribution area where the deviation area has abnormal deviation. The abnormal value of the deviation area is queried and counted, and the counting result is retrieved as the abnormal number value for subsequent use.

The abnormal number impact value is determined by querying the abnormal number value, which is convenient for subsequent use.

[0139] Step S278: Determine the area anomaly impact value based on the deviation area anomaly value and the deviation center position point analysis.

[0164] Step S510: Determine whether the slope adjustment value is less than a preset slope adjustment reference value. If yes, execute step S520; if no, execute step S530.

[0165] The slope adjustment reference value refers to the maximum reference value that the slope plate can adjust, and the slope adjustment reference value is obtained after being pre-input by the operator.

[0169] Among them, the slope adjustment deviation value refers to the deviation value when there is a deviation in the slope adjustment.

[0197] Among them, the specification grinding adjustment position point refers to the position point after the grinding position is adjusted. The position of each specification grinding reference position point is adjusted through the slope adjustment position influence value, thereby forming the specification grinding adjustment position point for subsequent use.
