Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] The present invention provides a grinding method based on torque feedback of abrasive grain size gradient change, such as figure 1 shown, including the following steps:

[0026] Step S10, calibrate the stable torque T i with grit size w i relationship, including:

[0027] Under the action of constant load P, different particle sizes w are selected i Grinding the grinding surface with the abrasive until the torque reaches the stable torque T i , to obtain a stable torque T i with grit size w i The relationship between; abrasive particle size w i It can be W20~60, such as: 60, 100, 240, W40, W20, and when the abrasive particle size is w i When they are 60, 100, 240, W40, and W20, respectively, the corresponding stable torques are T 60 , T 100 , T 240 , T w40 , T w20 ;

[0028] Step S20, calibrating the surface roughness Ra of the stab...

Abstract

The invention discloses a grinding method based on the gradient change of abrasive grain size based on torque feedback. The grinding method comprises the following steps: calibrate the relationship between the stable torque and the grain size of the abrasive, and calibrate the relationship between the surface roughness of the stable grain size and the grain size of the abrasive. Relationship, determination of gradient abrasive particle size, and grinding technology based on torque feedback gradient change of abrasive particle size for matching grinding processing. The above-mentioned matching research method can effectively improve the efficiency and quality of matching research.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for mixing and grinding abrasive grain size gradient changes based on torque feedback. Background technique [0002] Coupled parts represented by valve seat and valve core refer to two parts that match and cooperate with each other and must be manufactured in pairs and cannot be interchanged or configured. In the machining of precision couplers, not only the precision of the part itself is extremely high, but the tolerance requirements between the two mating parts are also very strict. Matching and grinding is an effective method for processing the paired parts. Realize the cooperation of couples. The matching between the valve seat and the valve core is usually a typical axial matching, which is the middle and advanced stage of the development of the coupler manufacturing industry. With high-efficiency and high-precision processing equipment combined wi...
