Description
Technical field
The present invention relates to field of machining, and in particular to handle lock processing method.
Background technology
In machine industry, handle lock metal parts, such part wall thickness very thin (2 ~ 8mm), size are frequently encountered
Precision and surface quality requirements height, outside dimension larger (300 ~ 800mm), complicated, poor rigidity, clamping get up very not
Just, piece surface is easily injured, therefore, manufacture difficulty is very big, once manufacture qualification rate is very low, even if using advanced numerical control lathe
The equipment such as bed, easily cause the deformation of product assembly to influence precision when using lathe in machining.
A kind of handle lock part is processed, its cylindrical tolerance 0.06mm, axiality requires 0.1mm, part thinnest part wall thickness
Only 2.25mm, excircle dimension, which reaches, many places skewed slot on 500mm, outer round surface, domestic common processing method is：Numerically controlled lathe
Clamping with three-jaw chuck is simultaneously corrected, then fine turning outer circle and endoporus respectively；But when fine turning outer circle and endoporus, workpiece is because in material
Stress variation and be easily deformed, there is different degrees of change and causes overproof in the final size of product, but can not return
Repair, overproof more can only directly scrap.In addition, after processing excircles and endoporus, in addition it is also necessary to process skewed slot using machining center
And side opening, now, product design have been finished in place, periphery can not be over-stressed, it is impossible to is corrected using soft pawl, any
Clamping force is likely to deform it for thin-wall part.Therefore, operation of the existing processing method both for processor is passed through
Test requirement very high, meanwhile, machining yield is again relatively low, otherwise cause product yield not increase, or because vital part can not add
Work and complete machine part or complete set of equipments can not be manufactured.
External current way has plenty of by improving the performance parameters such as raw material quality, including forging, heat treatment, so that
Improve stability of material, reduce machining deformation；Or by increasing the manufacturing procedure of part, i.e., first ensure cylindrical and endoporus chi
Very little precision substantially in place after, then process the partial structurtes such as other grooves, hole, finally by amendment surface quality make size and surface
Satisfactory quality.But above-mentioned way all can substantially increase manufacturing cost and the manufacturing cycle of part, part or institute are directly resulted in
The price of complete machine of application rises, and the cost performance of product declines.
The content of the invention
In order to solve the above problems, the present invention provides a kind of convenient and practical, economically feasible, it is ensured that the machining accuracy of workpiece,
And with substantial economics and social effect, can not only effectively improve product manufacturing precision and performance, can also promote
Enter the handle lock processing method of the development of China's machining manufacturing technology.
Handle lock processing method of the present invention, comprises the following steps：
The first step, using numerically controlled lathe semifinishing, the cylindrical and endoporus of workpiece leaves surplus；
Second step, upper ringfeder inner-hole frock finishing is cylindrical, after the ringfeder excircle dimension of ringfeder inner-hole frock and semifinishing
Inner hole of workpiece size is fit dimension, and ringfeder is opening, and ringfeder inner-hole frock is put into after inner hole of workpiece, by ringfeder
Nut on hole tool, which is extruded, causes ringfeder expansion, so as to play tensioner effect, is then finished to cylindrical；
3rd step, upper double team outer circle tool set finishes endoporus, and the sleeve pipe of the frock is divided into three parts, and card is passed through respectively per part
The soft pawl of disk is fixed on chuck, and the hole size of sleeve pipe and the excircle dimension of workpiece are fit dimensions, under frock relaxed state,
By clamping workpiece in sleeve pipe, the soft pawl of chuck is fastened, workpiece is packed tightly, is then finished to endoporus；
4th step, the frock of upper processing groove, the location-plate and supports support workpiece of the frock, location-plate is provided with bolt hole,
It will be fixedly clamped by interior hexagonal double-ended bolt in the middle part of workpiece, support member is supported to the end of workpiece, the frock determines processing
The position of groove is completed by location-plate, and location-plate is provided with some positioning holes, is additionally provided with before location-plate and perpendicular is determined
Position pin, precision and the alignment pin of positioning hole match, and location-plate coordinates alignment pin often to rotate the angle in a hole, just can determine one
The Working position of individual groove, and then the processing for carrying out groove is locked to steering wheel.
Convenient and practical, economically feasible of the invention, it is ensured that the machining accuracy of workpiece, and anticipated with substantial economics and society
Justice, can not only effectively improve product manufacturing precision and performance, and China can also be promoted to be machined the hair of manufacturing technology
Exhibition.
