Abstract

The invention discloses a clamp for fixing a bottom plate and polishing the bottom plate provided with stepped holes. The clamp comprises a supporting shaft, a pressing ring and a tightening bolt, wherein the top of the supporting shaft is provided with an extending lug boss in a step shape gradually thickened from top to bottom, the extending lug boss and the pressing ring are matched with two stepped holes of different diameters in the bottom plate respectively, a fixed hole matched with the tightening bolt is arranged in the pressing ring, and the end face of the extending lug boss is provided with a fixed thread hole matched with the tightening bolt. The bottom plate can be fixed through the clamp. The bottom plate does not move during polishing, so the polished surface quality is ensured.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for grinding a bottom plate provided with stepped holes. Background technique [0002] During the production process of the optical microscope, the end face of the bottom plate needs to be polished. In the actual grinding process, the base plate is usually pressed on the worktable by hand, and then the end face of the base plate is polished with sandpaper. In fact, it is difficult to press the bottom plate to the worktable when grinding, and the bottom plate keeps moving on the worktable, which affects the surface quality after grinding. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fixture for grinding a bottom plate with stepped holes which can fix the bottom plate. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a fixture for grinding the bot...
