Devices for grinding fragile workpieces

Abstract

The invention discloses a device suitable for grinding fragile workpiece. The device is characterized in that a workpiece is arranged on one inner side surface of one side of an n-shaped frame, the workpiece is pressed with a gasket by a setscrew at the other side of the n-shaped frame after the setscrew penetrates through the frame, an opening of the n-shaped frame is arranged on a grinding disc, more than two sliding rods are fixed below a support and are in sliding connection with a tray and the n-shaped frame after penetrating through the tray and the n-shaped frame, one end of a spring, positioned among the sliding rods, is connected with the tray, the other end of the spring is connected with the upper end of the n-shaped frame, the sliding rods are vertical to the grinding disc, and a heavy object is put on the tray. In the invention, the working principle is of a passive type, the functions of the device can be realized without additional control and feedback mechanisms, the device has a simple and smart structure and low cost, can be applied to automatic grinding equipment, can reduce dependence degree on the planeness of a grinding surface, and can fast and accurately grinding the workpiece with low damage. When used for grinding crisp and fragile materials, the device has more obvious advantages.

Description

technical field [0001] The invention relates to a grinding device, in particular to a device suitable for grinding fragile workpieces. Background technique [0002] In recent years, the invention and application of new materials have advanced by leaps and bounds. At the same time, it also brings more challenges to the processing of some new materials, including low-damage grinding of brittle materials. Due to the micro-cracks on the surface of the workpiece during the grinding process, and the grinding surface has certain unevenness, the resulting intermittent scratches or impacts will aggravate the growth of micro-cracks on the surface of the workpiece and increase the probability of workpiece fragmentation. Especially workpieces composed of brittle materials, such as glass, ceramics, nanomaterials, and silicon-based chips, are more sensitive to chipping due to unevenness of the grinding surface. The requirements of modern precision engineering for the control of microcra...

Problems solved by technology

The traditional manual operation has been difficult to meet the accuracy requirements due to its operational errors such as pressure and angle, and faces problems such as low efficiency and safety factors; the use of traditional grinding equipment is safer and more efficient, but it is caused by uneven grinding surfaces. The problem of workpiece fragmentation is still not effectively solved
