Abstract

The invention relates to the field of machining, in particular to an eccentric sleeve machining method. The eccentric sleeve machining method includes: cutting the bar of an eccentric sleeve blank to allow the same to be parallel with an end face at one end, and drilling a central hole in the end face; using a three-jaw self-centering chuck to clamp one end of the blank on a machine tool, using the movable live center on the tailstock of the machine tool to push against the other end of the blank, rough turning the excircle of the blank, and reserving a machining allowance of 1-2mm; removing the live center, using the three-jaw self-centering chuck to clamp the excircle of the blank, reserving an appropriate extra length, and machining an eccentric sleeve; using an appropriate flat-head drill bit to drill the central hole of the eccentric sleeve, and allowing the depth of the hole to be larger than the length of the eccentric sleeve; machining the excircle of the eccentric sleeve to the required size on the machine tool, chambering the central hole, and not chambering the eccentric hole of the eccentric sleeve. By the method, product quality can be increased, machining precision is unaffected by product deformation during machining, rejection rate is lowered, and production efficiency is increased greatly.

Description

Eccentric bushing processing method
Technical field
The present invention relates to field of machining, be specifically related to eccentric bushing processing method.
Background technology
Eccentric shaft is more common in present plant equipment, and eccentric bushing is as the kit of eccentric shaft, the scope of application is also more extensive, because eccentric bushing belongs to thin-wall sleeve, easily there is distortion in process, cause machining accuracy not meet the demands, and due to the effect of cutting force, be easy to occur waste product, add difficulty of processing.
Summary of the invention
In order to solve the problem, the invention provides one can improve the quality of products, and ensures that the distortion of product in process can not affect machining accuracy, rate of reducing the number of rejects and seconds, the eccentric bushing processing method of simultaneously greatly enhancing productivity.
Eccentric bushing processing method of the present invention, comprises the following steps:
The first step, cuts concordant one end end face by the bar of eccentric bushing blank, then drill centers on this end face;
Second step, with one end of three-jaw self-centering chuck clamping blank on lathe, the movable live centre top tight workpiece on other end tail stock, by rough turn for blank cylindrical, and stays the allowance of 1mm-2mm;
3rd step, removes tail stock top, with three-jaw self-centering chuck clamping blank cylindrical, leaves and appropriate adds length, processing eccentric bushing;
4th step, bore eccentric bushing centre bore for suitable countersinking bit, hole depth is greater than eccentric bushing length;
5th step, being by eccentric bushing Excircle machining to requiring size at lathe, carrying out reaming to centre bore, but not to the eccentric orfice reaming on eccentric bushing;
6th step, by eccentric cushion block pad to the arbitrary claw on three-jaw self-centering chuck, then by Workpiece clamping, carrying out centering with magnetic force dial gauge, eccentric throw meets dimensional requirement, is machined to by eccentric orfice and requires size;
7th step, adopts cutoff tool to be cut by the eccentric bushing processed, ensures the tolerance of eccentric bushing length, when workpiece is about to cut, catch workpiece with wooden stick, in order to avoid workpiece damages because of collision.
The present invention can improve the quality of products, and ensures that the distortion of product in process can not affect machining accuracy, rate of reducing the number of rejects and seconds, greatly enhances productivity simultaneously.
Detailed description of the invention
Eccentric bushing processing method of the present invention, is characterized in that, comprise the following steps:
The first step, cuts concordant one end end face by the bar of eccentric bushing blank, then drill centers on this end face;
Second step, with one end of three-jaw self-centering chuck clamping blank on lathe, the movable live centre top tight workpiece on other end tail stock, by rough turn for blank cylindrical, and stays the allowance of 1mm-2mm;
3rd step, removes tail stock top, with three-jaw self-centering chuck clamping blank cylindrical, leaves and appropriate adds length, processing eccentric bushing;
4th step, bore eccentric bushing centre bore for suitable countersinking bit, hole depth is greater than eccentric bushing length;
5th step, being by eccentric bushing Excircle machining to requiring size at lathe, carrying out reaming to centre bore, but not to the eccentric orfice reaming on eccentric bushing;
6th step, by eccentric cushion block pad to the arbitrary claw on three-jaw self-centering chuck, then by Workpiece clamping, carrying out centering with magnetic force dial gauge, eccentric throw meets dimensional requirement, is machined to by eccentric orfice and requires size;
7th step, adopts cutoff tool to be cut by the eccentric bushing processed, ensures the tolerance of eccentric bushing length, when workpiece is about to cut, catch workpiece with wooden stick, in order to avoid workpiece damages because of collision.
