Abstract
The invention discloses a method for processing an inner tapered hole of a fan. The technical problem of reaming the inner tapered hole of a large thin-wall piece with an outer diameter of 1.8 meters, inner taper of 1: 8, a large diameter of phi89 and high tolerance in a numerically controlled vertical lathe is solved. The method has the advantages that: the technical problem of reaming the inner tapered hole of the large thin-wall piece with the outer diameter of 1.8 meters, the inner taper of 1: 8, the large diameter of phi89 and the high tolerance in the numerically controlled vertical lathe is solved; quality requirements of the similar inner tapered hole on relatively high size precision, relatively high shape and position tolerance precision and the like are met; and due to the one-time reaming molding, the production efficiency is improved by about 50 percent.
Description
Technical field
The present invention relates to field of machining, especially relate to a kind of fan internal taper hole processing method.
Background technology
The processing of the taper hole of generally having relatively high expectations all is to adopt grinding and ream technology, and wherein grinding is on internal grinder, to pass through wheel grinding, and its technological process is roughly: rough turn, finish turning, grinding; Ream then is on drilling machine or milling machine (comprising numerical control device), to carry out, and its technological process is roughly: boring, reaming, ream; The general size and the surface accuracy of hole processing of only guaranteeing gets final product.But for large thin-wall element, external diameter reaches 1.8m, and inner cone is 1:8; Big footpath is Φ 89, and internal taper hole has the contact-making surface requirement, is benchmark; The axiality of it and top macropore is had relatively high expectations; This design feature has just determined it can not use process program commonly used, because grinding machine can not get out of the way the external diameter of 1.8m, and can not guarantee the axiality requirement with the top macropore on drilling machine or the milling machine.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of fan internal taper hole processing method, solved the technology difficult problem that on numerical control vertical lathe ream external diameter reaches 1.8m, inner cone 1:8, large thin-wall element internal taper hole that big footpath Φ 89 tolerances are high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of fan internal taper hole processing method comprises the steps:
The first step, with the rough turn circle in each of roughing tool, with lengthening boring cutter heavy boring internal taper hole;
Second step, each interior circle of finish turning, right boring internal taper hole:
Water excircle of workpiece with cooling fluid, fully cool off workpiece, loose chuck discharges behind the stress centering clamping work pieces again; With each interior justifying of finishing tool finish turning to the designing requirement size; With lengthening boring cutter right boring internal taper hole, the tapering that makes internal taper hole is 1:8;
The 3rd step, thick fraising:
Slightly cut with scissors internal taper hole with reamer, tapering 1:8, technological requirement: the hinge circle gets final product, and checks contact-making surface with feeler gauge, and the contact-making surface that reaches more than 80% requires to get final product;
The 4th goes on foot, finish reams the hole:
Finish ream internal taper hole with reamer, tapering 1:8, technological requirement: check contact-making surface with feeler gauge, the contact-making surface that reaches more than 80% requires to get final product; Measure diameter D with micrometric depth gauge simultaneously, until reaching designing requirement.
Compared with prior art; Good effect of the present invention is: through the enforcement of this programme; Solve external diameter and reached 1.8m, inner cone 1:8, the big directly processing technology difficult problem of the large thin-wall element internal taper hole of Φ 89; Guaranteed quality requirements such as size that such internal taper hole is higher and form and position tolerance precision, and disposable ream is shaped and has improved production efficiency about 50%.
The specific embodiment
A kind of fan internal taper hole processing method comprises the steps (annotate: following steps are all processed) on the 2m numerical control vertical lathe:
The first step, rough turn each interior circle, heavy boring internal taper hole:
With rough turn each the interior circle of roughing tool; With lengthening boring cutter heavy boring internal taper hole, the monolateral fine finishining amount 1～1.5mm that stays, because this product structure sealing, cooling fluid can't thoroughly be removed in the later stage, therefore, can not open cooling fluid in the processing, machining deformation is bigger like this, notes allowance.
Second step, each interior circle of finish turning, right boring internal taper hole:
Water excircle of workpiece with cooling fluid, fully cool off workpiece, loose chuck discharges behind the stress centering clamping work pieces again; With each interior justifying of finishing tool finish turning to the designing requirement size; With lengthening boring cutter right boring internal taper hole, the tapering that makes internal taper hole is 1:8, and the monolateral fine finishining ream surplus of staying is shaped most effective and reamer wear extent minimum at 0.2～0.5mm to guarantee a ream.
The 3rd step, thick fraising:
Slightly cut with scissors internal taper hole with reamer; Tapering 1:8; Wherein speed setting 4～15r/min (rpm), the amount of feeding is set in 0.1～0.3mm/r (millimeter revolution), to guarantee in the prerequisite decurrence through reamer life-span of satisfying the contact-making surface requirement, to guarantee about 1 time/500 of reamer reconditioning cycle.Technological requirement: the hinge circle gets final product, and checks contact-making surface with feeler gauge, and the contact-making surface that reaches more than 80% requires to get final product; If the relatively poor angle, edge front and back that needs the inspection reamer of inspection contact-making surface is if there are wearing and tearing to need reconditioning.
The 4th goes on foot, finish reams the hole:
Finish ream internal taper hole with reamer, tapering 1:8, wherein speed setting is set in 0.1～0.3mm/r at 4～15r/min, the amount of feeding, to guarantee in the prerequisite decurrence through reamer life-span of satisfying the contact-making surface requirement, to guarantee about 1 time/500 of reamer reconditioning cycle.Technological requirement: check contact-making surface with feeler gauge, the contact-making surface that reaches more than 80% requires to get final product; Measure diameter D with micrometric depth gauge simultaneously, until reaching designing requirement.
In the technological design process, the lengthening boring cutter is used in boring, can guarantee the boring degree of depth requirement of internal taper hole; The reamer that ream uses needs to select by the internal taper hole dimensional requirement; The connection handle of a knife of reamer need adapt to the design feature of 2m numerical control vertical lathe equipment and reamer, is used for reamer and equipment are effectively coupled together; Feeler gauge needs to select by this internal taper hole dimensional requirement, is used to detect the internal taper hole size.
