Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing equipment, in particular to a surface processing equipment for automobile wheel hubs. Background Art

[0002] The wheel hub is a cylindrical metal component with the inner contour of the tire supporting the tire and the center mounted on the shaft. It is also called a rim, steel ring, wheel or tire bell. There are many types of wheel hubs depending on the diameter, width, molding method or material. In the past, the most common wheel hub bearings for cars were used in pairs of single-row tapered roller or ball bearings. The outer ring surface of the wheel hub needs to be polished during the processing. For example, a surface treatment device for the outer ring of an automobile wheel hub with publication number CN214489914U includes a base, a column is welded and fixed to one side of the base, a groove is opened in the column, a reciprocating screw is rotatably connected in the groove, a processing component is threaded on the reciprocating screw, a rotating shaft and a rotating rod are rotatably connected to the base respectively, a rotating component is welded and fixed on the rotating rod, a fixed seat is welded and fixed on the top of the rotating shaft, slide grooves are symmetrically opened in the fixed seat, and a slider is slidably connected in each of the slide grooves. The utility model provides structures such as a driving component, a lead screw and a first conical wheel, and the hexagonal nut pushes the slide block to clamp or disengage the inner walls of wheel hubs of different specifications, and the nut can drive the grinder to move up and down in a vertical plane to grind the upper and lower surfaces of the automobile wheel hub, and the fixed seat can rotate to rotate the fixed wheel hub so that the entire outer ring surface of the wheel hub is fully processed; when fixing the wheel hub, it is necessary to first place the wheel hub on the fixed seat, and then the staff member's arm passes through the wheel hub surface and rotates the hand so that the hexagonal nut pushes the slide block to clamp or disengage the inner walls of wheel hubs of different specifications, which is relatively troublesome, and when grinding the upper and lower surfaces of the outer ring of the wheel hub, it is necessary to manually rotate the wheel clockwise and counterclockwise, so that the grinder moves up and down in the vertical direction, which is time-consuming and labor-intensive.
