Embodiment Construction

[0019] The present invention is described in detail below in conjunction with embodiment.

[0020] like figure 1 As shown, the extra-large spherical surface integrated precision grinding system of the present invention includes: a sphere driving part 3, a first grinding wheel abrasive 2, a second grinding wheel abrasive 4, a third grinding wheel abrasive 7, a grinding abrasive 6 and a detection component 5. They are in the same X, Y, Z rectangular coordinate system, the X, Y, Z rectangular coordinate system includes the origin O, the horizontal coordinate axis X, the horizontal coordinate axis Y and the vertical coordinate axis Z. The sphere center of the ground sphere 1 of the super-large spherical surface coincides with the origin O, and in the X, Y, Z rectangular coordinate system, the rotation center line of the sphere driving part 3 coincides with the horizontal coordinate axis X, and the first grinding wheel The rotation center line of tool 2 and the rotation center lin...

Abstract

The invention discloses an integrated precision grinding system and an integrated precision grinding method for an extra-large spherical surface. The grinding system comprises a sphere driving part, a first grinding wheel grinding tool, a second grinding wheel grinding tool, a third grinding wheel grinding tool, an abrasion grinding tool and a detection part, which are in the same X, Y and Z right-angled coordinate system. The grinding method comprises the following steps that the sphere driving part drives a ground sphere to rotate, the second and third grinding wheel grinding tools grind the left and right sides of the rotating ground sphere, the first grinding wheel grinding tool starts grinding the ground sphere after the ground sphere is ground by a certain depth by the second and third grinding wheel grinding tools, the second and third grinding wheel grinding tools stop grinding when a grinding depth is to be reached, the first grinding wheel grinding tool continues grinding the ground sphere until the size of the sphere is detected to meet a requirement, and the abrasion grinding tool performs abrasion treatment on the ground sphere. The method is used for the integrated precision grinding machining of distributed grinding, abrasion and detection of the extra-large ground sphere under a once mounting condition.

Description

technical field [0001] The invention relates to a spherical surface precision grinding device and method in the technical field of machine tools, in particular to an extra large spherical surface integrated precision grinding system and method. Background technique [0002] Extra-large and high-precision spheres are key components in fluid and gas control devices (such as large ball valves) in major projects such as large-scale oil and gas transmission and large-scale hydropower generation. At present, the diameter of the extra-large sphere has exceeded 2500mm, and the weight exceeds 20t. Due to the requirements of sealing and working performance, this kind of super large sphere has high requirements on surface roughness and geometric accuracy. Therefore, the surface of the sphere must be precision ground and ground before it can be used. High requirements for geometric accuracy (sphericity), high requirements for surface roughness, and large grinding area are technical dif...
