Description

Technical Field

[0001] The utility model specifically relates to the technical field of needle roller grinding, in particular to a grinding machine for needle roller processing. Background Art

[0002] When the needle roller is installed and used, the surface accuracy and smoothness must be guaranteed, so that the needle roller can be installed in the bearing to effectively ensure the working efficiency of the bearing. However, when traditional needle rollers are processed, grinding is usually used to process the surface, which has low processing accuracy and slow working efficiency.

[0003] At present, when processing traditional needle rollers, grinding wheels or grinding belts are usually used to effectively process and grind the surface of the needle rollers. However, such equipment usually requires manual conveying of the needle rollers during processing, which will cause potential threats during processing. In this way, manual conveying of the needle rollers has low work efficiency.

[0004] After searching, Chinese patent publication number CN202320748378.4 discloses a bearing needle roller grinding machine; including an operating table, the bottom surface of the operating table is symmetrically fixed to the top surface of the support base, the top surface of the operating table is provided with a movable groove, a fixing component is installed in the movable groove, the top surface of the operating table is fixed to the bottom surface of the fixed plate, the top surface of the fixed plate is provided with a fixed groove, the bottom surface of the fixed groove is fixed to one end of an electric push rod, the other end of the electric push rod is fixed to the bottom surface of the moving table, the top surface of the moving table is evenly provided with a plurality of placement grooves, the bottom surfaces of the placement grooves are respectively fixed to the bottom surfaces of the contact pads; one end of a support rod is symmetrically fixed to the four corners of the top surface of the operating table, the other end of the support rod is respectively fixed to the four corners of the bottom surface of the support plate, and the support plate is provided with mounting holes;

[0005] The structure in the above patent, when grinding the needle roller, places a plurality of needle rollers in the placement groove, and then controls the driving motor through the control panel to drive the grinding rollers to rotate respectively, and then moves the mounting plate downward through the cylinder, so that the grinding rollers contact the surfaces of the needle rollers respectively, so as to grind the needle rollers. However, the structure in the above patent can only process a certain number of needle rollers at a time during grinding, so that the grinding efficiency is low during processing and production, and the needle rollers need to be replaced frequently; during grinding, the production efficiency cannot be effectively improved;

[0006] In view of the above situation, we provide a grinding machine for needle roller processing. In this device, the needle roller is loaded in an orderly manner through a vibrating loading tray, and the needle roller is transported between the first grinding wheel and the second grinding wheel through a connecting frame in the vibrating loading tray to achieve grinding of the needle roller surface, wherein the second grinding wheel is movably installed compared to the first grinding wheel. In this way, when grinding the needle roller, the grinding machine can effectively grind needle rollers of different diameters by adjusting the distance between the second grinding wheel and the first grinding wheel, thereby greatly improving work efficiency and greatly reducing the involvement of personnel through effective loading through the vibrating loading tray.
