Abstract
The invention discloses a method for manufacturing a high-accuracy rotating shaft by a surface grinding machine, comprising the following steps of: (a) fixing a stop shaft gauge block on the workbench of the surface grinding machine; (b) flatly placing a to-be-machined slender shaft on the workbench of the surface grinding machine, and closely attaching the generatrix of the to-be-machined slender shaft with the stop shaft gauge block; (c) rocking a grinding wheel with a hand to perform a vertical feeding movement, so as to perform tool setting and feeding; (d) starting the surface grinding machine, rotating the grinding wheel under the driving of a motor, and rotating the to-be-machined slender shaft by using the motor or manpower, so as to ensure total-generatrix grinding; and (e) after the to-be-machined slender shaft is grinded until the diameter thereof achieves a predetermined dimension, stopping, taking off the to-be-machined slender shaft, and then finishing the grinding operation. According to the invention, the excircle generatrix of the to-be-machined slender shaft is supported by virtue of the workbench of the surface grinding machine, so that the bending deformation of the to-be-machined slender shaft cannot be caused by the feeding force of the grinding wheel, thus improving the accuracies of geometric tolerances such as the straightness and cylindricity of the slender shaft, and having a high yield.
Description
Technical field
The present invention relates to precise machine machining field, particularly relate to a kind of method that surface grinding machine manufactures high-precision rotary axle.
Background technology
The revolving parts of required precision is had usually to adopt cylindrical grinder to carry out production and processing.The operation principle of cylindrical grinder part to be processed is fixed on spindle chuck rotate with main shaft, abrasive grinding wheel High Rotation Speed also moves reciprocatingly along axis of workpiece direction, length feed with emery wheel progressively removes allowance, finally makes workpiece reach size and the precision of drawing requirement.But, diameter and length than the slender axles being less than 10 when grinding, due to the poor rigidity of slender axles, easy generation bends, easily form waist-drum-shaped or pyramid type after making slender shaft turning, the precision comparison of the form and position tolerances such as the linearity of slender axles and cylindricity is low, easily produces waste product.
Summary of the invention
The object of the invention is to provide a kind of surface grinding machine to manufacture the method for high-precision rotary axle for the deficiencies in the prior art.
For achieving the above object, the present invention is achieved through the following technical solutions.
Surface grinding machine manufactures a method for high-precision rotary axle, comprises the steps:
A gear shaft gauge block is fixed on the workbench of surface grinding machine by ();
B slender axles to be processed are lain against the workbench of surface grinding machine by (), make the bus of slender axles to be processed and gear shaft gauge block fit closely;
C () hand grinder does vertical feed campaign and carries out tool setting and feeding;
D () starts surface grinding machine, emery wheel rotates under the drive of motor, adopts motor or manually makes slender axles to be processed rotate, ensureing full bus grinding;
E the diameter of () slender axles to be processed is ground to preliminary dimension after, shuts down, take off slender axles to be processed, so far, complete grinding work.
In a step, the length of gear shaft gauge block is consistent with the width of workbench, and in b step, the height of gear shaft gauge block is 3/4 ~ 4/5 of the diameter of slender axles to be processed.
In a step, gear shaft gauge block, by after square centering, is arranged on the position at 10 ~ 100 millimeters to the left of workbench center.
In a step, workbench is provided with electromagnet, and gear shaft gauge block adopts and can be made by the material of electromagnetic actuation, and start electromagnet, gear shaft gauge block is adsorbed on workbench by electromagnet securely.
In Step d, each amount of feeding of emery wheel is 1/5 of allowance, and is less than 0.002 millimeter.
In Step d, when the width of emery wheel is less than the length of slender axles to be processed, need hand shaken handwheel, workbench is moved forward and backward, completes grinding work.
In Step d, cooling fluid need be sprayed to slender axles to be processed.
Beneficial effect of the present invention is: the present invention utilizes the worktable support of surface grinding machine to live the cylindrical bus of slender axles to be processed, make emery wheel centripetal force can not cause the flexural deformation of slender axles to be processed, improve the precision of the form and position tolerance such as linearity and cylindricity of slender axles, yields is high.
