2results about How to "Uniform grinding force" patented technology

This utility model discloses an external cylindrical grinding device, including a base, a workpiece driving mechanism, and a grinding mechanism. The grinding mechanism includes a crank mechanism, a guide rail, and a grinding block. A slider is slidably mounted on the guide rail, and the slider is connected to the crank mechanism, which drives the slider to slide along the guide rail. A vertical groove is formed on the upper side of the slider, and the grinding block is slidably mounted in the groove. A spring is provided between the grinding block and the bottom of the groove. Under the action of the spring, the upper end of the grinding block can extend out of the groove to fit tightly against the surface of the workpiece to be ground. This utility model, by employing a grinding device with a certain degree of elasticity, can adapt to different types of shaft workpieces to be ground, has good versatility, and during secondary processing, the grinding block can always be tightly fitted against the surface of the workpiece under the action of the spring, avoiding the impact of workpiece jump during secondary clamping on the original shape and position accuracy.

The utility model belongs to the technical field of lens processing equipment, especially relates to a gas float mechanism of lens fine grinding and polishing machine, including gas float mechanism, rotary drive mechanism, swing adjusting mechanism and position adjusting mechanism. The gas float mechanism includes fixed base, main shaft, lower supporting ring and lower ball basin. The lens polisher provided in the application can drive the lower ball basin to realize rotary motion and swing motion simultaneously, ensures that each part of the lens can be evenly polished, improves the surface quality and optical precision of the lens, sets up the air inlet on the lower supporting ring, can set the lower ball basin to float on the top side of the lower supporting ring after connecting the external air source, forms the air film between the lower ball basin and the lower supporting ring, avoids the direct contact of both, reduces the friction resistance, makes the rotary motion of the lower ball basin more smooth, effectively improves the rotary speed, and improves the lens polishing efficiency and uniformity.
