The invention discloses a machining device for an eccentric sleeve with an included angle between a hole axis and an excircle axis. The machining device comprises a base plate, a workpiece positioning device and a boring bar support sleeve, wherein the workpiece positioning device is fixed on the base plate and can fixedly position a to-be-machined workpiece; a set included angle is formed in two side edges, in the axial direction of the workpiece, of the base plate; the axis of the to-be-machined workpiece is parallel to one side edge, in the axial direction of the to-be-machined workpiece, of the base plate; the boring bar support sleeve is fixed on the base plate, and a central hole of the boring bar support sleeve is coaxial with the workpiece. The workpiece is mounted and calibrated conveniently, the machining accuracy is high, the workpiece can be positioned in the axial direction accurately through a positioning disc, the position of an intersection of an eccentric hole and the workpiece axis is guaranteed, and the machining device is simple and compact in structure and convenient to use and adjust, and can guarantee the machining accuracy of the eccentric hole of the workpiece.
Description
technical field [0001] The invention relates to a processing device for special parts, in particular to a processing device for an eccentric sleeve with an included angle between the axis of a hole and the axis of an outer circle. Background technique [0002] The high-precision CNC roll curve grinder is a roll grinding equipment for cold-rolled steel plates, and has high requirements; the grinding head part adopts a new mechanism. The main components are: outer cast iron eccentric sleeve, inner main shaft eccentric sleeve, main shaft, etc. Compared with the traditional structure, the outer cast iron eccentric sleeve is added, and the cast iron sleeve structure is such that the angle between the inner and outer circular axes is 1°. When the mechanism drives the outer circular axis of the cast iron eccentric sleeve to rotate, the main shaft placed in the cast iron eccentric sleeve can , the eccentric sleeve swings at a small angle, so that the main shaft of the grinding whee...
