AI Technical Summary
The existing grinding machine has low accuracy when machining the spherical base surface of the workpiece end face. This is because the forming diamond roller makes point contact with the machining surface, resulting in an approximate machining surface.
Design a special grinding machine for the end face of a roller ball base. It adopts a grinding wheel mechanism and a workpiece feeding mechanism. The inner wall of the grinding wheel cup is dressed by a diamond roller dresser so that it corresponds to the ball base surface. The grinding wheel cup is then in contact with the workpiece surface for processing.
This improves the machining accuracy of the workpiece's spherical base surface, ensuring that the machined surface matches the spherical base surface and avoiding the phenomenon of approximate machining.

Description
Technical fields:
[0001] This utility model belongs to the field of grinding technology, and specifically relates to a special grinding machine for the end face of a roller ball base. Background technology:
[0002] When producing the spherical base surface of a workpiece end face, a grinding machine is needed to grind the spherical base surface. In the existing production process, a shaped diamond roller is generally used to trim the machined surface. The shaped diamond roller contacts the machined surface through the roller blade. This contact is a point contact, so the machined spherical base surface is approximate and the machining accuracy is low.

The workpiece loading mechanism includes a diaphragm chuck, which is movably set on the worktable. The clamping position at the front end of the diaphragm chuck is opposite to the cup-shaped inner wall of the grinding wheel. The cup-shaped inner wall of the grinding wheel is processed by the diamond roller dresser, and the cup-shaped inner wall of the grinding wheel is processed into a mechanism corresponding to the spherical base surface. The cup-shaped inner wall of the grinding wheel forms a surface contact with the workpiece processing surface, thereby shaping the spherical base surface of the workpiece.

[0010] By dressing the inner wall of the grinding wheel to make its structure correspond to the spherical base surface, the workpiece surface is machined through surface contact with the inner wall of the grinding wheel.

The dressing surface of the diamond roller dresser 23 is located on the rotation trajectory of the grinding wheel 15, and the dressing surface of the diamond roller dresser 23 contacts the bowl-shaped inner wall of the grinding wheel 15.
[0020] In use, the grinding wheel 15 moves horizontally towards the clamping position under the drive of the grinding frame slide 10.
