Abstract
The invention relates to a pulley batch machining method which mainly solves the problems that an existing pulley is low in machining efficiency, high in rejection rate and high in labor intensity of workers. The method is characterized by including the following steps that (1) all faces are machined through a common lathe, all the faces except a right inner circular face (A) are machined to the sizes meeting the requirements of a drawing, and the right inner circular face (A) is machined to ; (2) copper flexible jaws are welded to the work face of a clamping jaw of a numerical control lathe, and then finish turning is carried out on the inner surfaces of the copper flexible jaws through an internal bore turning tool; (3) the right inner circular face (A) is machined to through the numerical control lathe at a constant speed. When the method is adopted to machine pulleys, the fact that the dimensional tolerance of the products is within the required range is guaranteed, labor intensity is reduced, machining time is saved, efficiency is improved, and the rejection rate is reduced.
Description
Technical field
The present invention relates to a kind of mechanical field, specifically a kind of pulley batch processing method.
Background technology
P70 lorry door part need to be used a kind of pulley, and rolling bearing need be inlayed by this pulley interstitial hole place, is specifically of a size of
tolerance only has 0.02mm(to be commonly called as " twice ").At present this pulley adopts the processing of CA6140 lathe conventionally, right-hand member (
nose end) a turning moulding of each size, and then the turning left end that turns around.The shortcoming of this processing method is: 1, production efficiency is low,
place's tolerance only has twice, and very difficult processing needs repeatedly test run after rough turn, and test run limit, limit is measured with inside micrometer, repeatedly just can reach requirement after repeatedly, and efficiency is low; 2, high to operator's specification requirement, the very difficult qualification rate that guarantees bulk article concerning general technology workman, and labour intensity is large, and cost of labor is high; 3, percent defective is higher,
place's tolerance is easy to overproof and occurs waste product, as the factors such as operate miss, measured deviation, thermal deformation all can affect the margin of tolerance.
Summary of the invention
In order to overcome existing pulley, process above-mentioned deficiency, the invention provides a kind of pulley batch processing method, adopt the method processing pulley, can be in the dimensional tolerance that guarantees product in claimed range, and reduced labour intensity, saved process time, raise the efficiency the rate of reducing the number of rejects and seconds.
Technical scheme of the present invention is: a kind of pulley batch processing method, comprises the following steps:
(1), adopt engine lathe to process each face, each size except the inner headed face of right side is all machined to drawing requirement, right side inner headed face is machined to
(2), on the working face of numerically controlled lathe claw, weld respectively the soft pawl of copper, then with internal lathe-tool by the soft pawl inner surface of copper finish turning once;
(3), adopt numerically controlled lathe with constant speed processing right side inner headed face extremely
The soft pawl of copper in described step (two) is used finish turning again after one or two month, so repeatedly, when it cannot clamping workpiece, is pulled down, more again welds a soft pawl of copper.
The present invention has following beneficial effect: owing to taking such scheme, the pulley of original employing engine lathe processing is divided into the processing that combines of engine lathe and numerically controlled lathe, utilized the rough turn good rigidly of engine lathe, intensity feature good, that chip removal is good to carry out rough turn, utilize the feature that numerically controlled lathe repetitive positioning accuracy is high, automaticity is high, mechanical clamped cutting tool finish turning precision is high to carry out processing key size, can greatly improve working (machining) efficiency, can reduce labor strength low, alleviate workman's the amount of labour.Meanwhile, minute two procedures processing can effectively solve the thermal deformation producing due to cutting, and numerically controlled lathe can also be poured into a mould sufficient cutting fluid, also solved the problem of inner headed face place, right side processing influence of thermal deformation precision, reduce percent defective, greatly improved product quality
Accompanying drawing explanation
Fig. 1 is the structural representation of the workpiece processed of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, a kind of pulley batch processing method, comprises the following steps:
(1), select engine lathe, as CA6140 lathe is processed each face, each size except the inner headed face A of right side is all machined to drawing requirement, inner headed face A place, right side allowance
be machined to
now will guarantee that allowance will unify, otherwise smear metal thin and thick is inconsistent, " cutter relieving " size there is not rule can affect the machining accuracy of subsequent step, but concerning operator, the tolerance of 0.2mm is easy to hold, not high to workman's specification requirement.After processing, with regard to vernier clamp, check.
(2), on the working face of numerically controlled lathe (as CAK6150) claw, weld respectively copper billet, make the soft pawl of copper of not hindering workpiece, again with internal lathe-tool by the soft pawl inner surface of copper finish turning once, make itself and main shaft keep coaxial, to guarantee the axiality after workpiece processing.The soft pawl of copper needs finish turning again after using one or two month, determines the finish turning time of the soft pawl of copper according to the degree of wear of the workpiece quantity of processing or the soft pawl of copper.So repeatedly, when it cannot clamping workpiece, pulled down, more again welded a soft pawl of copper, after finish turning, used.
(3), adopt numerically controlled lathe with constant speed processing right side inner headed face A extremely
at this moment need unified feed speed, because same lathe tool, same allowance in the situation that, different feed speeds can cause the size after turning to have the variation of 0～0.01mm, therefore, processing herein will keep constant feed speed, take FANUC system as example, and feed speed is used F0.1 when multiplying power is 100 ﹪ herein.After processing, fabricated part is tested.
Batch by a period of time is produced as a trial, and processing method of the present invention has improved the quality of product greatly, 3～5 ‰ the percent defective of fundamentally having stopped to be caused by original processing mode.When reducing labor intensity, make production efficiency improve 30% left and right.Meanwhile, the present invention can be applied to, on similar other products, as processing of the piston rod in the processing of the bearing block in railway wagon hand brake machine, graduated release valve etc., in actual production, produce huge economic benefit equally.
Claims (2)
1. a pulley batch processing method, is characterized in that comprising the following steps:
(1), adopt engine lathe to process each face, each size except right side inner headed face (A) is all machined to drawing requirement, right side inner headed face (A) is machined to
(2), on the working face of numerically controlled lathe claw, weld respectively the soft pawl of copper, then with internal lathe-tool by the soft pawl inner surface of copper finish turning once;
