Description
Technical field:
The present invention relates to the removal method of gear-hobbing burr in a kind of Gear Processing.
Background technology:
Gear is the important foundation part in the engineering goods.Gear hobbing is straight-tooth and the most frequently used processing method of helical teeth involute cylindrical gear.In the going out on the cutter direction of hobboing cutter, the end face of gear usually produces gear-hobbing burr inevitably during gear hobbing.
For gear-hobbing burr, must be removed.Because burr can directly have influence on the operating accuracy and the properties of product of gear.Particularly those have the gear of clear and definite high requirement to gearing noise, and gear-hobbing burr must thoroughly be removed clean, otherwise the gearing noise index is difficult to reach instructions for use.
At present, most manufacturers all adopt the plucked method of pincers worker.This method has fairly obvious shortcoming:
1) labour intensity is very big, and operating efficiency is very low.Need pincers worker to remove burr with file or gear ground of gear of brass wire brush; To the gear of gearing noise requirement is arranged, even need every gear one tooth one tooth ground removal burr.
2) burr is difficult to remove clean.Such as medium and small modulus soft tooth flank gear, high rigidity large module gear, not only unhairing difficulty, and very difficult the removal totally.
Also there are some manufacturers after gear hobbing, to increase the operation of one face work, reach the purpose of removing burr with the method for face work.Undeniable, this a kind of really than the high method of the little efficient of pincers worker unhairing labour intensity.But this method has tangible deficiency equally: car has removed the burr of gear face, but makes burr turn over into teeth groove.Finally must pincers worker remove burr in the teeth groove with brass wire brush.
Summary of the invention:
The objective of the invention is to: a kind of removal method of brand-new gear-hobbing burr is provided, and this method can be removed clean burr, can enhance productivity again, reduce production costs.
The present invention is achieved in that it may further comprise the steps:
The first, workpiece to be processed (4) clamping on gear-hobbing machine (5), and is adjusted the location;
Second, the dedicated elas-tic knife rest (3) that will have unhairing knife (1) is installed on the pedestal or post of gear-hobbing machine (5), adjust the position of unhairing knife (1), make unhairing knife (1) surpass the design attitude of tooth root in the horizontal direction slightly earlier, the knife face that goes out that is slightly higher than workpiece in vertical direction is the A face, press down unhairing knife (1) then, make it be close to the going out on the knife face A face of workpiece (4) under effect of dedicated elas-tic knife rest (3) inner spring (2);
The 3rd, start gear-hobbing machine (5) and carry out gear hobbing processing, the rotating band of hobboing cutter is started building part (4) along the rotation of the workpiece centre of gyration, and unhairing knife (1) is removed the burr that workpiece (4) goes out on the knife face A face.If burr turns over into teeth groove, the cutting edge of hobboing cutter will turn over the into burr removal of teeth groove so.
Used a kind of dedicated elas-tic knife rest (3) in the above method, this dedicated elas-tic knife rest mainly is made up of parts such as unhairing knife (1), spring (2), sliding bars.Sliding bar stretches out on the end of pedestal and is processed with a square hole, and unhairing knife (1) is installed in this square hole; By tightening the fixed-site of housing screw assurance unhairing knife (1); The extension elongation of unhairing knife (1) can be adjusted as required, adjusts the extension elongation of unhairing knife (1) if desired or changes unhairing knife (1), unclamps housing screw and gets final product; Spring (2) is installed in pedestal and the formed circular trough of sliding bar.
Because workpiece has the existence of mismachining tolerance inevitably when processing tooth base, on gear-hobbing machine the time, its high and low position that goes out knife face A face can be slightly different with clamping workpiece.In order to make unhairing knife energy unhairing, need accomplish 2 points simultaneously: 1, unhairing knife will be close to going out on the knife face A face of workpiece all the time; 2, unhairing knife with respect to workpiece go out knife face A face, to have one to upward pressure all the time.These 2 all is to realize by the spring in the dedicated elas-tic knife rest.
The present invention removes burr in gear hobbing: because the unhairing knife on Elastic tool post and the Elastic tool post is all fixed, the drive workpiece that rotatablely moves of hobboing cutter rotates along the workpiece centre of gyration during gear hobbing, this motion is with respect to the unhairing knife on the Elastic tool post, the relative motion of workpiece and lathe tool when being similar to lathe turning.Therefore, when the going out knife face A face and produce burr of workpiece, the unhairing knife on the Elastic tool post is just removed burr; If burr turns over into teeth groove, hobboing cutter its cutting edge in gear hobbing will turn over the into burr removal of teeth groove so.
The present invention is applicable to a type gear and dish-type type gear part.Because the difference of these two types of gear parts, they are slightly different at the installation way that rolls on the bed when only being gear hobbing.Facts have proved that adopt the present invention to remove burr, the unhairing effect is fine.
Because the present invention utilizes the unhairing knife on the dedicated elas-tic knife rest and the cutting edge of hobboing cutter to remove burr in gear hobbing, has reduced pincers worker unhairing or the plucked operation of lathe face work, thereby has improved production efficiency widely, has reduced production cost.
