Numerically controlled grinder

Abstract

The invention relates to a numerically controlled grinder for forming and grinding an intermediate shaft channel of a rzeppa coupling. A numerical control system is respectively connected with servo motors and a stepping motor. A servo motor 1, a servo motor 2 and a servo motor 3 are respectively arranged on a grinding head frame, a stand column and a grinder body pedestal to respectively realize linear motion of the numerical control system in the Z direction, the X direction and the Y direction. A servo motor 4 is connected with a dividing mechanism to realize numerical control division or axial rotation of a workpiece; the stepping motor is connected with a trimmer to realize gyroscopic motion of a diamond pen; a grinding wheel spindle is driven by a grinding head motor to provide grinding main movement; the numerically controlled grinder is provided with a semi-closed shield, an air draft and dedusting system and a cooling and circulating system; and the servo motors are driven by a four-axis linkage numerical control system, and the stepping motor and the four-axis linkage numerical control system are controlled by a program controller. The invention is widely applied to carrying out ground finish on various curved surfaces of metal parts. In the invention, motion and positioning of the components can be numerically controlled and operated, the automation degree is high, the grinding wheel dressing precision is high, the working surface is smooth, the workpiece division accuracy is accurate, the labour environment can be improved and the labour intensity can be reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a special numerically controlled grinding machine for channel forming of an intermediate shaft of a reinforced straight channel ball cage coupling. Background technique [0002] The two ends of the intermediate shaft of the reinforced straight channel ball cage coupling are designed with several straight channels parallel to the axis of the intermediate shaft as the inner sleeves of the two couplings. The cross-section of each channel is elliptical, and the steel ball corresponding to the coupling has two contact points, and the angle between the two contact points has special technical requirements. There are several different structural forms of such workpieces, the typical structure of which can be found in Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 . [0003] The grooves at both ends of the intermediate shaft are finally finished by...

Problems solved by technology

At present, the processing technology and process equipment used in domestic processing of similar workpieces are basically ground on ordinary tool grinders or spline shaft grinders with low automation. Simple Dresser Manual Dressing of Grinding Wheels

The manual indexing accuracy of the universal dividing head is low, and the quality of the manual dressing of the grinding wheel is poor, so that the groove formed by grinding cannot meet its technical requirements; at the same time, there are many adjustment elements during the dressing of the grinding wheel and grinding, which must be done manually, which is labor-intensive. Moreover, this kind of simple processing equipment has no dust-proof facilities, especially when dressing the grinding wheel, there is a lot of dust, and the working environment for workers is poor.
