Abstract

The invention provides a double-end-face grinding machine dressing device. The double-end-face grinding machine dressing device comprises a main body, a power mechanism, a transmission mechanism and a dressing mechanism, wherein the power mechanism drives the dressing mechanism to rotate through the transmission mechanism; the dressing mechanism comprises a dressing shaft and a dressing disc; the dressing disc is mounted on the dressing shaft; a plurality of dressing oil stones are arranged in the peripheral direction of the dressing disc; one end of each dressing oil stone protrudes out of the upper surface of the dressing disc and the other end of each dressing oil stone protrudes out of the lower surface of the dressing disc; and the main body is provided with an adjusting mechanism for adjusting a swinging center of the dressing disc to be parallel to a rotary center of a grinding wheel. According to the double-end-face grinding machine dressing device, the sharpness retentivity of the grinding wheel is better and the self-sharpening performance is better; more workpieces can be ground between two times of dressing frequencies; and the size precision and the surface precision of the machined workpieces can be improved. The dressing time is saved and the utilization rate of a machine tool is improved. The dressing device is mounted on a grinding machine box body and an adjustable structure is adopted, so that the parallelism of a dressing center and the center of the lower grinding wheel is easy to guarantee, and furthermore, the whole manufacturing difficulty of the machine tool is reduced and the assembling efficiency is improved.

Description

technical field [0001] The invention relates to a grinder, in particular to a dressing device for a double-end grinder. Background technique [0002] The traditional double-end grinding machine uses the oil cylinder to drive the swing arm to drive the diamond pen to dress the grinding wheel; the original dressing structure is only suitable for dressing ordinary corundum grinding wheels. As CBN and diamond grinding wheels are more and more widely used, the original swing arm dressing method drives a single oilstone dressing wheel, which usually takes a long time to dress, and the initial dressing even takes 5-8 hours, seriously affecting production efficiency. [0003] The dressing device of the grinding wheel generally uses manual or oil cylinder as the power source. Manual dressing is unsafe and inefficient. The stroke of the dressing stone is limited, the single movement trajectory is short, the dressing area is small, and the dressing efficiency is low. [0004] Vertical...
