Centering accurate-grinding device for metal bobbin

Abstract

The invention provides a centering accurate-grinding device for a metal bobbin, belonging to the technical field of textile machinery. The centering accurate-grinding device comprises a centering clamping rotary mechanism and an accurate grinding mechanism. The lower end of an upper clamping piston rod of an upper clamping component of the centering clamping rotary mechanism is connected with an upper clamping centering block, and a lower centering cylinder block of a lower clamping component is concreted above a lower pressing plate. A lifting lead screw of a lifting component of the accurategrinding mechanism is in threaded connection with a lifting lead screw nut, and a first curved surface and a second curved surface are symmetrically arranged at the two ends of an accurate grinding sliding block of an accurate grinding component. A third accurate grinding wheel is rotationally arranged at the other end of a carrier rod. A first transfer roller is rotationally arranged at one endof a first swing arm, and a first accurate grinding wheel is rotationally arranged at the other end of the first swing arm. A second transfer roller is rotationally arranged at one end of a second swing arm, and a second accurate grinding wheel is rotationally arranged at the other end of the second swing arm. The centering accurate-grinding device can realize accurate grinding for a taper-pipe-shaped metal bobbin and has strong applicability to the metal bobbin.

Description

technical field [0001] The invention relates to the technical field of processing spare parts of textile machinery, in particular to a centering fine grinding device for metal bobbins. Background technique [0002] Textile machinery is all kinds of mechanical equipment needed to process natural fibers or chemical fibers into textiles. Although the machinery for producing chemical fibers includes a variety of chemical machinery, it is now considered an extension of textile machinery and belongs to textile machinery in a broad sense. The processes required to process different fibers such as cotton, hemp, silk, wool, etc. into textiles are not the same, and some are completely different, so the machines required are also various and varied. Textile machinery is usually classified according to the production process, including: spinning equipment, weaving equipment, printing and dyeing equipment, finishing equipment, chemical fiber spinning equipment, reeling equipment and non...

AI Technical Summary

Problems solved by technology

At present, common metal yarn tubes generally need to be finely ground on the outer surface, but the current common fine grinding equipment can only achieve fine grinding of cylinders, which is not suitable for the fine grinding of such conical tubes with different diameters at both ends.
