Rolling needle polishing device and application method thereof

Abstract

The invention discloses a rolling needle polishing device and an application method of the rolling needle polishing device. The rolling needle polishing device comprises a base. A sliding rail is installed on the upper surface of the base in the length direction, a collecting box with an opening is connected with the side wall of the base in a contact mode, and vertical and upward supporting rodsare further symmetrically welded on the top surface of the portion, located on the outer side of the sliding rail, of the base. A sliding plate is movably connected to the sliding rail, and a lanternring A and an air cylinder are fixedly arranged on the top end face of the sliding plate. The area of the region of intersection of the lantern ring A and a lantern ring B is increased; rolling needles are placed in the region of intersection of the lantern ring A and the lantern ring B, and the lantern ring B moves after the region is filled with the rolling needles which need to be polished as many as possible; when the area of the region of intersection is reduced, the rolling needles are completely attached together until an air cylinder rod cannot move, and the lantern ring B stops movingwhen the air cylinder rod cannot move; the sliding plate is pushed so that the tops of the rolling needles can be completely polished to be smooth after the rolling needles make contact with a rotating grinding wheel; and the sliding plate is dragged out after polishing is accomplished, the lantern ring B is moved, and the rolling needles can be taken out.

Description

technical field [0001] The invention relates to a grinding device, in particular to a needle grinding device and a use method thereof. Background technique [0002] In the process of producing and processing needle roller rolling elements, due to misoperation or mechanical equipment, the produced rolling elements do not meet the process requirements, and the length of the rolling elements may be long or the end face of the rolling elements is perpendicular to the central axis. Out-of-tolerance, commonly known as the horseshoe-shaped end face, affects the quality of the needle roller. When grinding the horseshoe-shaped needle roller, it is easy to cause residues to fly randomly, cause damage to the environment, and may also cause harm to people. The number of needle rollers polished at one time is fixed. Dead, causing problems that cannot be fixed when the number of needles is small. Contents of the invention [0003] The object of the invention is to provide a needle roll...

[0002] In the process of producing and processing needle roller rolling elements, due to misoperation or mechanical equipment, the produced rolling elements do not meet the process requirements, and the length of the rolling elements may be long or the end face of the rolling elements is perpendicular to the central axis. Out-of-tolerance, commonly known as the horseshoe-shaped end face, affects the quality of the needle roller. When grinding the horseshoe-shaped needle roller, it is easy to cause residues to fly randomly, cause damage to the environment, and may also cause harm to people. The number of needle rollers polished at one time is fixed. Dead, resulting in unfixable problems when the number of needles is small
