Method and system for grinding double sides of disc type rotary work piece, and vertical double-sided grinding machine with numerical control synchronous double-sided grinding head

Abstract

The invention relates to a method for grinding double sides of a disc type rotary work piece, a double-sided grinding system and a vertical double-sided grinding machine. The method is to grip a work piece on a transfer system through an inverted rotary gripping mechanism, and feed the work piece into a vertical double-sided grinding device to grind double sides of the work piece. The system grinds the work piece by adopting the vertical double-sided grinding machine. The grinding machine is provided with a double-sided grinding head consisting of an upper grinding wheel and a lower grinding wheel which are oppositely arranged; the two grinding wheels are parallel to each other, are positioned on the top of the grinding head device, and are connected with a grinding wheel rotary drive system which can lead the two grinding wheels to rotate synchronously, wherein at least one of the grinding wheels is connected with a grinding wheel vertical motion drive system. The method, the system and the grinding machine are beneficial to improvement of the manufacturing efficiency, ensure that the horizontally placed work piece is uneasily deformed in grinding, guarantee high precision processing of the thin-disc type work pieces, have stable system performance, easily realized structure, convenient installation and small occupied space, can be widely applied to double-sided synchronous grinding of various parts, and are mainly used for processing of the disc type rotary work piece and other disc shaped work pieces.

Description

technical field [0001] The invention relates to a method for double-sided grinding of disc-like rotary workpieces, a double-sided grinding system adopting the method and a vertical double-sided grinding machine for the system provided with a numerically controlled synchronous double-sided grinding head. Background technique [0002] The existing methods of grinding rotary workpieces such as brake discs for automobiles mostly adopt horizontal single-sided grinding and horizontal double-sided grinding methods. First, the vertical straight clamping mechanism is used to clamp the disc-type rotary workpieces from the conveyor belt, and then manually or mechanically The rotary workpiece of the disk type is transferred into the horizontal clamping mechanism by means of the horizontal clamping mechanism, and then sent to the horizontal single-sided grinding machine for grinding. In order to improve production efficiency, some enterprises also use the horizontal double-sided grinding ...

AI Technical Summary

Problems solved by technology

The main defects of this technology are: First, due to the use of a horizontal grinding machine, a horizontal clamping mechanism must be used to send workpieces such as disc-type rotary workpieces into the processing position of the grinding machine, so when the vertical clamping mechanism is used to clamp the workpiece Finally, it is necessary to send the workpiece into the horizontal clamping mechanism, which not only makes the structure of the entire processing system complex and high in cost, but also increases the workload and reduces production efficiency; , when processing thin discs, one-way processing extrusion deformation is caused, the thickness of the workpiece is uneven, and the processing accuracy is not high. The method of horizontal double-sided grinding can solve the problem of meeting the precision requirements of thin disc processing, but this method is different. There are two sets of rotating grinding wheels and feeding systems, and the mechanism of the inverted horizontal clamping device for automatically clamping the workpiece from the conveyor belt is complex and costly, and the existing double-sided grinding equipment cannot solve this problem well
