Universal automatic composite abrasive wheel trimming machine

Abstract

The invention relates to a universal automatic composite abrasive wheel trimming machine. The trimming machine comprises a workpiece work mechanism, a trimming mechanism, a detection mechanism and a motion control mechanism. The workpiece work mechanism adjusts an abrasive wheel to the position needed for trimming. The trimming mechanism comprises a trimming feeding device, a main shaft S2, a laser trimming device, an electric spark trimming device and a mechanical trimming device. The laser trimming device, the electric spark trimming device or the mechanical trimming device moves to the position needed for trimming to trim an abrasive wheel. The detection mechanism comprises a projection monitoring device and a repeated reflection detection device. The projection monitoring device monitors trimming of the abrasive wheel in real time. The repeated reflection detection device conducts online repeated reflection method detection on trimming of the abrasive wheel, and the detection result is transmitted to the motion control mechanism. The motion control mechanism controls the actions of the workpiece work mechanism, the trimming mechanism and the detection mechanism according to thejudgment result. The universal automatic composite abrasive wheel trimming machine is low in cost, high in efficiency and precision, wide in adaptability, high in automation degree and simple in operation.

Description

technical field [0001] The invention relates to a grinding wheel dressing machine, in particular to a universal automatic compound grinding wheel dressing machine. Background technique [0002] Grinding wheel, also known as bonded abrasive tool, is a bonded abrasive tool with a certain strength by bonding ordinary abrasives into a certain shape (such as a circle with a through hole in the center), which is generally composed of abrasive, bonding agent and pores. These three parts are often referred to as the three elements of a bonded abrasive. Grinding wheels are classified according to different binders, and the common ones are vitrified bond grinding wheel, resin bond grinding wheel and metal bond grinding wheel. Grinding wheel is one of the most used and most widely used abrasive tools. It rotates at high speed during use and can perform rough grinding, semi-finishing and fine grinding on the outer circle, inner circle, plane and various profiles of metal or non-metal w...

AI Technical Summary

Problems solved by technology

For example: the dressing tool wears quickly and the precision is not high during the dressing of turning method and cup-shaped grinding wheel; the dressing precision of diamond roller is high, but the efficiency is not high, and the roller profile is complex, which is difficult to manufacture; the dressing precision of EDM is higher, But the trimming speed is slow; the electrolytic trimming method is fast but difficult to trim, and due to the influence of the electric field, flow field, and electrode reaction dynamic process between the cathode tool and the grinding wheel, the machining gap is not equal everywhere, so that the surface roughness to be trimmed Not ideal; the electrolytic trimming method needs to be equipped with a dedicated power supply, electrodes and electrolyte, the device is more expensive and has certain special requirements

It can be seen that the current metal-based diamond grinding wheel dressing method more or less has the disadvantages of high dressing cost, low efficiency, low precision, narrow adaptability, low degree of automation, and complicated operation.
