Description

Automatic adjusting polisher

Technical Field

The utility model relates to a machinery of polishing field, in particular to automatically regulated polisher.

Background

The stainless steel welded pipe is manufactured by welding steel strips into a pipe, so that a welding seam is formed on the surface of the steel pipe and needs to be polished and removed; the common welding seam polishing accessory is generally a flap grinding wheel, and the flap grinding wheel is driven by the rotation of a motor to polish the welding seam. However, in the polishing process, the flap grinding wheel continuously polishes the weld joint to gradually wear the grinding wheel, the outer diameter of the grinding wheel gradually becomes smaller, so that the grinding depth of the grinding wheel to the weld joint gradually becomes shallow, the weld joint cannot be effectively polished due to over-shallow grinding, the quality of a steel pipe is affected, and secondary processing is required to be performed. The grinding depth is adjusted by manually adjusting the contact depth of the grinding wheel and the steel pipe after the grinding effect is judged, and the problems of low efficiency, poor quality uniformity and the like exist. In addition, in the actual production process of a factory, the production of steel pipes with other pipe diameters can be changed, the positions of welding seams with different pipe diameters are different, or the positions and angles of welding points of the steel pipes with different shapes are different, so that the positions of grinding wheels need to be adjusted in a targeted manner in order to effectively grind the welding seams during grinding. The polishing equipment is fixed in position when being installed, and the installation position is not easy to adjust, so that only an adjusting device on the equipment can be adjusted to adjust transversely and longitudinally. The traditional grinding machine can only carry out simple up-down left-right adjustment, and cannot carry out angle adjustment of grinding wheel grinding, so that the grinding effect of the traditional grinding machine is poor in grinding of steel pipes with large differences of positions and angles of partial welding points.
