Lower disc transmission mechanism of grinder or polisher

Abstract

The invention discloses a lower disc transmission mechanism of a grinder or a polisher. The lower disc transmission mechanism comprises a rack, a plurality of lower disc assemblies, a lower disc revolution mechanism and a lower disc autorotation mechanism. The lower disc revolution mechanism comprises a main tray, a spindle, a bearing seat, a main motor and a cam divider. The bearing seat is fixedto the rack; the spindle is vertically mounted in the bearing seat and driven by the main motor; the main tray is fixed to the upper end of the spindle; and the cam divider is driven by the main motor, the spindle is driven by the cam divider, and the position number of the cam divider is the same as the number of the lower disc assemblies. The spindle of the main tray is driven by the cam divider, the cam divider is a high-precision revolution device, thus a transmission gap does not exist, and the self-locking effect can be achieved; and the main tray driven by the cam divider can be precisely positioned when stopped, and a working disc does not shake circumferentially after being stopped, so that the workpiece machining quality is good.

Description

technical field] [0001] The invention relates to a grinding machine or a polishing machine, in particular to a lower plate transmission mechanism of a grinding machine or a polishing machine. Background technique] [0002] The single-side polishing machine is suitable for processing thin precision parts of ultra-thin hard and brittle materials. The traditional lower plate drive mechanism is processed by the revolution and rotation of multiple grinding discs. When the workpiece on one of the grinding discs is not completely processed after processing When the requirements are met, it is necessary to accumulate the majority after disassembly, and then install and process the second time. Secondary installation and processing will cause damage to the workpiece or non-parallel processing, which will make the workpiece scrapped. [0003] The invention with application number CN201710672447.7 discloses an intelligent multi-segment curved surface polishing machine, including: a wo...

Secondary installation and processing will cause damage to the workpiece or non-parallel processing, which will make the workpiece scrapped

However, the working disk of this invention is driven by the motor to rotate through the first transmission assembly to realize multi-station polishing, because the first transmission assembly includes a belt drive and a reduction mechanism, the transmission chain is very long, and the gap accumulated in the transmission chain is too large to make it work. When the disc is stopped, it cannot be precisely positioned and locked, and the working disc shakes left and right on the station, which affects the polishing quality of the workpiece

[0004] In addition, because the position of the detachable main shaft cannot be accurately positioned, the manipulator cannot be positioned to pick and place the workpiece, which increases the auxiliary time for product pick-and-place and reduces production efficiency.
