Description

Technical Field

[0001] The utility model relates to the technical field of end surface grinders, in particular to a bearing roller end surface grinder. Background Art

[0002] The bearing roller end face grinder is a highly efficient plane processing machine tool, which can grind two parallel end faces in one processing process. It can be divided into horizontal and vertical types according to the structure, and can be divided into through-type, turntable type and reciprocating type according to the feeding method. This machine tool is mainly used for grinding two parallel end faces of small and medium-sized bearing inner and outer rings, oil pump rotors, equal thickness connecting rods, retaining rings, piston rings, valve seats, valve plates, gears and traps, graphite blocks, flanges, copper and aluminum precision plates, etc. It can also be used for grinding other circular workpieces.

[0003] The patent document with publication number CN217122676U discloses a bearing roller end face grinder, including a cross slide, a worktable, a support wheel and a pressure wheel. The worktable is arranged above the cross slide, and several groups of height adjustment screw groups are arranged between the worktable and the cross slide. The support wheel and the pressure wheel are rotatably arranged on the worktable. There are two support wheels, and the two support wheels are axially inclined and arranged at one end of the grinding wheel. The two support wheels contact the outer diameter surface of the roller to be ground and support the roller. The pressure wheel presses the outer diameter surface of the roller to feed the roller along the inclined direction of the support wheel to keep the end face of the roller in contact with the grinding wheel for grinding; the pressure wheel is driven to rotate by a driving mechanism; the pressure wheel is rotatably connected to the worktable and approaches or moves away from the roller.

[0004] In the above technical solution, the clamping wheel is used to limit the grinding. The grinding wheel can only grind one end of the roller. When double-sided grinding is required, switching is required, and the process is too cumbersome. Therefore, we propose a bearing roller end grinder to solve this problem. Utility Model Content
