Problems solved by technology
[0003] There are certain problems in the above-mentioned conventional pre-grinding disc and polishing disc of the metallographic grinding and polishing machine: 1. The pre-grinding disc and the water sandpaper are not tightly bonded by water alone, and the edges are easy to lift, resulting in rapid damage and failure of the water sandpaper; 2. The pressure of the polishing disc The ring is easy to loosen under the condition of high-speed vibration, which will fly up and hurt people; 3. The difference between the local structure of the pre-grinding disc and the polishing disc and the way of fixing the grinding and throwing body make the two cannot be used universally, and the pre-grinding disc can only be realized with water sandpaper. Grinding function, the polishing disc can only use polishing flannelette to realize the polishing function

Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing:
[0025] Depend on Figure 1 to Figure 12 As shown, the grinding and polishing disc consists of a pressure ring, a disc body and a locking part.
[0026] The pressure ring is processed from a thin steel plate, and is an annular ring body, which is used to hold down water sandpaper or polishing flannelette. Four strips protrude from the outer edge of the pressure ring, and each strip is bent by 90° to match the small surface of the outer edge of the disc body; Tight fit.
[0027] The disc body is the main body of the grinding and polishing disc, which is disc-shaped and has a boss with a tapered hole in the middle of the lower end, which is used to be installed on the rotating shaft of the grinding and polishing machine. The upper surface of the disc body is flat and has no convex edges, and is used for distributing water sandpaper or polishing flannelette. Four facets are...

The utility model relates to a centrifugal locking type grinding and polishing disc of a metallographic grinding and polishing machine. The main purpose is to provide a centrifugal locking grinding and polishing disc used in a metallographic grinding and polishing machine, which can not only fix the water sandpaper, but also fix the polishing flannelette, and the water sandpaper or the polishing flannelette is fixed firmly, so as to realize the two functions of pre-grinding and polishing generic. It is characterized in that it includes a pressure ring, a disc body and a locking part; the pressure ring is a four elongated circular ring body protruding from an outer edge, which is used to hold down water sandpaper or polishing flannelette; the disc body is a grinding and polishing disc The main body has a boss in the middle of the lower end, which is used to install on the rotating shaft of the grinding and polishing machine; the locking parts include locking pins, small brackets, weight blocks, springs, top wires, etc.; the locking parts are divided into four groups, They are respectively installed on the lower surface of the outer edge of the disk in the direction of the small plane, and are used to clamp and lock the pressure ring on the upper surface of the disk.
Description
technical field [0001] The invention relates to a grinding and polishing disk applied to a metallographic grinding and polishing machine. Background technique [0002] Metallographic specimens are prepared using a metallographic grinding and polishing machine, which uses a motor to drive a pre-grinding disc or a polishing disc to rotate at high speed to grind the specimen. The disc-shaped main structure of the pre-grinding disc and the polishing disc is roughly the same, but there are differences in the mounting of the grinding and polishing bodies and their fixing methods. Conventional pre-grinding discs use water sandpaper to grind the specimen. The pre-grinding disc mainly relies on the adhesion force between the water sandpaper and the disc surface to fix the water sandpaper, and the edge of the pre-grinding disc has a convex edge to restrain the water sandpaper to prevent its radial movement. move. The conventional polishing disc uses a special flannelette to moisten ...
