Embodiment Construction

[0018] The method of grinding spherical surface provided by the present invention adopts such as Figure 1 to Figure 4 The ball grinding device in the shown embodiment, this workpiece grinding method is to use the chuck 14 to fix the workpiece 7 coaxially on the clamping end 61 of the clamping shaft 6, so that the surface of the spherical surface to be processed on the workpiece 7 The center of the sphere coincides with the center of rotation of the slewing mechanism. During grinding, the slewing mechanism drives the clamping shaft 6 to swing around the center of gyration of the slewing mechanism, and the clamping shaft 6 drives the workpiece 7 to rotate around the center of gyration Centering and swinging, at the same time, the clamping shaft 6 is driven by the shaft drive mechanism to drive the workpiece 7 to rotate around the central axis of rotation of the clamping shaft 6, and the grinding wheel 3 rotates around the central axis of rotation, and then the grinding surface o...

Abstract

The invention discloses a method for grinding the spherical surface of a workpiece. According to the method, the workpiece is coaxially and fixedly arranged at the clamping end of a clamping rotating shaft, so that the spherical center of the spherical surface to be machined on the workpiece is coincided with the revolving center of a revolving mechanism; during grinding, the clamping rotating shaft is driven by the revolving mechanism to do centering swing around the revolving center of the revolving mechanism, and the clamping rotating shaft is driven by a rotating shaft driving mechanism to drive the workpiece to rotate around the revolving central axis of the clamping rotating shaft; and a grinding wheel rotates around the revolving central axis of the grinding wheel, and a grinding working surface of the grinding wheel contacts the outer peripheral surface of the spherical surface to be machined on the workpiece to grind the workpiece. By the method, grinding errors are reduced effectively, and grinding accuracy is improved. In addition, the method for grinding the spherical surface is safe, reliable, simple, convenient, high in grinding efficiency and low in machining cost, and has high application value.

Description

technical field [0001] The invention belongs to the technical field of grinding, and in particular relates to a method for grinding a spherical surface of an end or part of a workpiece. Background technique [0002] The grinding of the workpiece end or partial spherical surface is much more difficult than the grinding of plane and cylindrical surfaces, especially when the grinding accuracy of the spherical surface is required to be high, the difficulty is even greater. However, manual grinding is labor-intensive, time-consuming and labor-intensive, and the grinding accuracy is low, so it is not suitable for mass production. [0003] A grinding method and a grinding device are disclosed in the invention patent application publication specification whose publication number is CN1810446A. The end spherical surface is ground. This grinding method cannot continuously adjust the grinding radius of the workpiece end, and the presence of ground abrasive grains inside the cup-shaped...
