A positioning mechanism for gear finishing grinding

Abstract

The invention discloses a gear finish machining grinding positioning mechanism, which comprises a feeding device, a fixed workbench, an adjustable positioning device, a grinder, a discharging roller bed, a workpiece gear, a discharging and pushing device, a lifting mechanism and a hydraulic station. The box type workbench is fixedly installed on the ground, and the box body of the workbench is provided with a set of lifting mechanism and hydraulic system; the adjustable positioning device is fixedly installed on a lifting sliding seat of the lifting mechanism, can move up and down in the central hole of the upper table of the fixed workbench with movement of the sliding seat, and is used for machining and positioning of gears; the grinder is fixedly installed on the upper face of the workbench, and a set of pushing device used for moving out finished products is further arranged on the side face of the workbench; and workblank of the workpiece gear is transmitted to the fixed workbenchthrough the feeding device, and then a finished product is transported to a next station through the discharging roller bed after being processed through positioning of the adjustable positioning device. The mechanism is arranged in line, degree of automation is high, positioning is precise and reliable, the processing quality can be effectively guaranteed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical fixtures, in particular to a positioning mechanism for gear finish machining and grinding. Background technique [0002] The flanging or burr produced by gear processing is traditionally processed by manual grinding with sand belt or file. With the continuous improvement of processing automation, this process has also begun to use machine tools for grinding and removal. Then the finished gear needs to be accurately and effectively fixed on the machine tool for grinding and processing. However, the clamping and fixing methods currently used mainly include: external pressure plate fixing, mandrel spline fixing, and magnetic chuck fixing. The above methods exist to varying degrees. Due to the influence of fixtures, processing is inconvenient. In addition, due to processing errors affecting positioning accuracy, subsequent dimensional deviations, and manual clamping and alignment are complicated an...

Then the finished gear needs to be accurately and effectively fixed on the machine tool for grinding and processing. However, the clamping and fixing methods currently used mainly include: external pressure plate fixing, mandrel spline fixing, and magnetic chuck fixing. The above methods exist to varying degrees. Due to the influence of fixtures, processing is inconvenient. In addition, due to processing errors affecting positioning accuracy, subsequent dimensional deviations, and manual clamping and alignment are complicated and difficult to operate. These problems affect product quality and production efficiency.
