The numerical-control cutter measuring device is characterized by comprising a bottom plate arranged on an end cover of a rocking platform, wherein one side of the upper part of the bottom plate is provided with a tail frame and a guiding rail positioned under the tail frame; the guiding rail is provided with a guiding-rail sliding block which can slide up and down along the guiding rail; a bearing seat is fixedly arranged at one side of the lower part of the bottom plate; a rotary shaft is arranged in the bearing seat; a cam is connected on the rotary shaft by keys and is connected with a pushing rod which is connected with a gauge stand arranged on the guiding-rail sliding block; the gauge stand supports a spring fixed on the tail frame. The numerical-control cutter measuring device has the advantages that when the radial run-out error of edges of outer cutters (inner cutters) of a cutter disc is measured, not only the adjacent inner cutters (outer cutters) can be effectively avoided so as to prevent from damaging a gauge head, but also the cutter measuring device can return the starting position accurately when the edges of the adjacent outer cutters (inner cutters) are measured, so that the measurement is more accurate.
Description
Technical field
The invention belongs to gear cutting machine field, particularly relate to a kind of milling machine of digital-control spiral conical gear and survey knife system.
Background technology
At present, the design of automobile drive axle spiral bevel gear mainly adopts two kinds of tooth systems: i.e. convergent tooth and equal-depth teeth.Convergent tooth is a kind of traditional main processing method, at home and abroad applies widely for a long time.And in recent years, designing and calculating and the processing adjustment of equal-depth teeth obtain very large simplification, the adjustment of contact zone is simultaneously also more simple and quick, and equal-depth teeth gear obtains applying more and more widely in automobile industry.The facing cutter that traditional processing equal-depth teeth and convergent tooth use is different, different according to the rotation direction of institute's machining gears, the difference that puts in order of various cutter tooth.When processing left-handed gear, with the left-handed cutterhead of turning anticlockwise; During processing dextrorotation gear, with clockwise pivotal dextrorotation cutterhead.Described cutterhead only has outer cutter, interior cutter two kinds of cutters tooth, adopts bar shaped tool section, three sharpenings.Be installed to again on cutter head after the outer cutter of facing cutter, interior blade mill, because adjustment and detection can exist certain error; In addition, cutter spindle also can produce error owing to assembling, and such facing cutter refills the run-out error that cutter spindle just may produce outer cutter, interior cutter, affects cutting precision.Therefore in the process of processing equal-depth teeth bevel gear, need the run-out error of the outer cutter of periodic measurement, interior cutter top and side cut blade position, when adopting traditional external cutter of amesdial or interior cutter to measure, in it, cutter (outer cutter) cutter hub can interfere the path playing table, in order to adjacent interior cutter (outer cutter) effectively can be got out of the way, in order to avoid damage gauge outfit, and measure the run-out error of blade, outer blade in cutterhead accurately, therefore a kind of cutter being applicable to equal-depth teeth milling is needed to survey knife system.
Summary of the invention
The present invention provides a kind of milling machine of digital-control spiral conical gear to survey knife system for solving in known technology the technical problem that exists, this survey knife system can realize the measurement of cutter blade and outer cutter blade run-out error in spiral bevel gear generator cutterhead, thus can meet the survey cutter demand of processing equal-depth teeth lathe.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is:
Milling machine of digital-control spiral conical gear surveys knife system, it is characterized in that: comprise the base plate be arranged on cage chair end cap, side, described base plate top is provided with tailstock and is positioned at the guide rail below tailstock, the guide rail slide block that can slide up and down along it described guide rail is equipped with, side, described base plate bottom is fixed with bearing block, described bearing block is built with rotating shaft, described rotating shaft is connected with cam by key, described cam is connected with push rod, described push rod is connected with the gauge stand be arranged on guide rail slide block, and described gauge stand withstands the spring be fixed on tailstock.
The present invention can also adopt following technical scheme:
Described rotating shaft is equipped with inner spacing collar, at rotating shaft terminal by bearings, and locks bearing inner ring, by ring flange rigid bearing outer shroud by locking nut and inner spacing collar.
Described rotating shaft spindle nose part adopts the outer hexagonal structure facilitating manual rotation.
Gauge stand is withstood in described regulating spring one end, and the other end is fixed on tailstock by adjustment screw.
The advantage that the present invention has and good effect are: when being arranged on cutter head after the outer cutter and interior blade mill of facing cutter, first the magnetic stand of amesdial to be fixed on gauge stand and to mix up amesdial, rotated by key band moving cam with the hand rotating shaft of spanner, because cam is provided with accurate large radius and minor radius, gauge stand can be promoted accurately retreat, play table and stopwatch, measure the interior cutter blade of facing cutter and outer cutter blade run-out error respectively alternately, namely with the outer cutter blade of the large radius measurement of cam, cutter blade in measuring by minor radius.And being arranged on the spring force size of the spring between adjustment screw and gauge stand to adjustment by thread spindle, spring can make gauge stand reset.Can make when measuring cutter (interior cutter) blade run-out error outside cutterhead like this, not only effectively get out of the way adjacent interior cutter (outer cutter), to avoid damaging gauge outfit, and table position can have been got back to exactly when measuring adjacent outer cutter (interior cutter) blade, make measurement more accurate.
