Abstract
The invention belongs to the field of the machining method, in particular to a follow grinding method for crankshaft pin, which is in particular characterized in that two rotation axes with the centerlines parallel to each other; the first rotation axis is connected with a crankshaft and drives the crankshaft to rotate and the rotation centerline of the first rotation axis coincides with the centerline of the crankshaft main journal; a grinding carriage is arranged on the second rotation axis, the centerline of the grinding wheel is parallel to the centerline of the rotation axis, and the distance from the centerline of the grinding wheel to the centerline of the second rotation axis is equal to the eccentricity of the center of the crankshaft pin; a horizontal guide rail is arranged below the second rotation axis. An included angle between a connecting line between the centerline of the crankshaft pin and that of the first rotation axis and a horizontal plane is adjusted to be the same with the included angle between the connecting line between the centerline of the grinding wheel and the centerline of the second rotation axis and the horizontal plane. The two rotation axes are rotated synchronously, and the position of the horizontal guide rail is adjusted, and thus a connecting rod journal with a required diameter can be manufactured. The follow grinding method of the invention has high machining accuracy, high efficiency and good economy.
Description
Technical field
The invention belongs to machining methods, specifically is a kind of follow grinding method of crank-shaft link neck.
Background technology
In machine driving, usually use bent axle, bent axle is owing to have a lot of gears not on same axis, adding necessary multiple clamping grinding in man-hour, cause grinding efficient low, and machining accuracy is also wayward, and the follow grinding method that adopts when existing crank-shaft link neck grinding needs the grinding carriage guide rail to do quick servo-actuated, technical very difficult realization, and the cost height, precision is low.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of follow grinding method of rational in infrastructure, practical and convenient, crank-shaft link neck that precision is high is provided.
Technical scheme of the present invention is as follows:
A kind of follow grinding method of crank-shaft link neck, it is characterized in that: two rotating shafts that center line is parallel to each other are set on a horizontal plane, first rotating shaft connects bent axle and drives crankshaft rotating, its rotation centerline and main bearing journal central lines, on second rotating shaft grinding carriage is housed, the emery wheel center line is parallel to rotating shaft center's line and equals the eccentric throw at crank-shaft link neck center with the distance of second rotating shaft center's line on the grinding carriage, one horizontal guide rail is housed below second rotating shaft, and its direction of motion is vertical with the rotating shaft center line; With the line between crank-shaft link neck center line and the first rotating shaft center's line and the angle between the horizontal plane is adjusted to and emery wheel center line and second rotating shaft center's line between line identical with the angle between the horizontal plane; Rotate two rotating shafts synchronously, emery wheel can be processed into circle with the connecting rod neck, and the connecting rod neck can be processed into required diameter in the position of adjusting horizontal guide rail.
The present invention is owing to adopt two rotating shafts, grinding carriage and bent axle are contained in respectively on two rotating shafts, there is a horizontal guide rail rotating shaft below of dress grinding carriage, with this servo-actuated method machining crankshafts connecting rod neck, simplified numerical control program, reduced requirement, the machining accuracy height digital control system, the efficient height, good economy performance.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, a kind of grinding processing method of crank-shaft link neck, it is characterized in that: two rotating shafts that center line is parallel to each other are set on pedestal 6, first rotating shaft 3 connects bent axle and drives crankshaft rotating, its rotation centerline and main bearing journal central lines, on second rotating shaft 1 grinding carriage is housed, emery wheel center line 2 is parallel to rotating shaft center's line and equals the eccentric throw at crank-shaft link neck center with the distance of second rotating shaft, 1 center line on the grinding carriage, one horizontal guide rail 5 is housed below second rotating shaft 1, and its direction of motion is vertical with the rotating shaft center line.Add man-hour, with the line between crank-shaft link neck center line 4 and first rotating shaft, 3 center lines and the angle between the horizontal plane is adjusted to and emery wheel center line and second rotating shaft, 1 center line between line identical with the angle between the horizontal plane, rotate two rotating shafts synchronously, emery wheel can be processed into circle with the connecting rod neck, and the connecting rod neck can be processed into required diameter in the position of adjusting horizontal guide rail.
