Description

Technical Field

[0002] The utility model patent with application number: CN201820365743.2 discloses a heat treatment loading rack for bearings, including a base, a slide plate, a support rod and a first nut. A plurality of vertical plates are arranged at equal intervals on the base, and the plurality of vertical plates are arranged parallel to each other. The slide plate is arranged one by one with the vertical plates. The slide plate is arranged on the vertical plates for sliding along the vertical direction. A first through hole is provided on the vertical plates along the vertical direction. One end of the support rod is abutted against the vertical plate at one end of the base. The other end of the support rod passes through the first through hole and is threadedly connected with the first nut. The first nut is abutted against the vertical plate at the other end of the base. A second through hole corresponding to the first through hole is provided on the slide plate, and a fixing mechanism for fixing the slide plate on the vertical plate is provided. The above technical scheme can adjust the height of the loading rack in the vertical direction by sliding the slide plate on the vertical plate. Since the fixing mechanism fixes the slide plate on the vertical plate, the furnace of different types of furnace bodies can be used, thereby improving the working efficiency of the loading rack, and it is not necessary to load it too many times in the heat treatment furnace for treatment.
