FIXTURE FOR GRINDING MACHINES

Abstract

A fixture for grinding machines includes a first base (10), a second base (20) and a driving component (40). The first base defines a first working groove (11) therein. The second base defines a second working groove (12) corresponding to the first working groove therein. The driving component is able to slide in the first working groove, and the driving component cooperates with the first base and the second base to releasably hold workpieces.

8. The fixture as claimed in claim 1, wherein the first base defines a plurality of grooves similar to the first working groove therein.

9. The fixture as claimed in claim 8, wherein the second base defines a plurality of grooves similar to the second working groove corresponding with the grooves defined on the first base.

10. The fixture as claimed in claim 1, wherein the fixture includes a plurality of partitions, the partitions are made of elastic material, and the partitions can slide in the first working groove.

11. The fixture as claimed in claim 10, wherein each partition includes a sliding portion and an extending portion, the cross section of the sliding portion coincides with the cross section of the first working groove, the extending portion connects with the sliding portion, and size of the extending portion is less than diameter of ground workpieces.

12. The fixture as claimed in claim 1, wherein the driving component includes a pushing board made of elastic material, the pushing board includes a sliding board and an extending board, the shape of the sliding board matches with the cross section of the first working groove, the extending board connects with the sliding board, and size of the extending board is less than a diameter of ground workpieces.

13. The fixture as claimed in claim 12, wherein the driving component includes two driving poles, the driving poles connect with each side of the extending board respectively.

14. A method of grinding workpieces, comprising the steps of: providing a fixture, the fixture including a first base defining a first working groove therein;a second base defining a second working groove corresponding with the first working groove therein; and a driving component being able to slide in the first working groove, t the driving component cooperating with the first base and the second base to releasably hold workpieces;securing a plurality of workpieces in the first working groove with a portion of each workpiece exposed outside the working groove, and grinding the exposed portion of each workpiece;releasing the workpieces from the first base;covering the first base with the second base, the ground portion of each workpiece engaging with the second working groove;turning the first base and the second base together, and separating the workpieces from the first base using the driving component;securing the workpieces in the second working groove, and grinding the exposed portion of each workpiece; andreleasing the workpieces and taking the workpieces away from the second base.
