Workpiece fixed-size compensation type double-sided grinding device and method

Abstract

The invention relates to a workpiece fixed-size compensation type double-sided grinding device and method. An upper fixed disk and a lower fixed disk are arranged in cooperation; the upper fixed disk is connected to a control mechanism; a sun gear is arranged in the middle of the lower fixed disk; a height meter is arranged in the axis of the sun gear; the top end of the height meter is right opposite to the center of the upper fixed disk; the height meter is connected to the control mechanism; and the control mechanism is connected with the upper fixed disk sequentially through a pneumatic mechanism and a cylinder; a planetary gear is meshed with the outer side of the sun gear and is provided with a through hole; and a lower fixed disk inner gear ring is meshed with the planetary gear. Through the combination with control over time and height, influences of the rotating speed, pressure and other external factors are eliminated during primary grinding, it is guaranteed that the measurement size is accurate, the workpiece measurement size value is relatively stable while the external factors are the same, the fixed-size grinding is performed at the moment, the size grinding technological requirement of a workpiece can be met at a time, the size of the ground workpiece is controlled through combination of grinding time control and height sensor control, control can be performed easily, the large-batch and automatic production requirement of the workpiece is met, and grinding precision is improved.

Description

technical field [0001] The invention belongs to the technical field of grinding or polishing machine tools, devices or processes, and particularly relates to a single grinding method that effectively avoids using time alone to control the size of the grinding workpiece or uses a height sensor to control the size of the grinding workpiece, so as to achieve more High grinding precision workpiece size compensation type double-sided grinding equipment and method. Background technique [0002] Double-sided grinding equipment is a grinding machine that grinds the surface of a workpiece with a grinding tool coated or embedded with abrasives. It is mainly used for double-sided grinding of crystals or other mechanical parts that are parallel to both sides. It is especially suitable for processing thin and brittle materials, such as Mechanical seal rings, ceramic discs, cylinder piston rings, oil pump blade bearing end faces, and surfaces of metal materials such as silicon, germanium,...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that, in the prior art, ordinary double-sided grinding equipment generally uses only the grinding time control or the height sensor to control the size of the workpiece to be ground, resulting in a single control method, light Time-based control is not conducive to control due to different benchmarks. Grinding by size alone cannot meet the needs of large-volume and automated production of workpieces, and the grinding accuracy is also low, thus providing an optimized workpiece sizing Compensation double-sided grinding equipment and method
