Description
Technical field:
The present invention relates to remove in a kind of Gear Processing the mechanical device of gear-hobbing burr.
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.During gear hobbing, go out at hobboing cutter on the gear face of cutter direction, usually produce gear-hobbing burr inevitably.
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 littler, method that efficient is high than pincers worker unhairing labour intensity.But this method has its significantly not enough equally: car has removed the burr of gear face, but makes burr turn over into teeth groove, finally must pincers worker removes burr in the teeth groove with brass wire brush.
Summary of the invention:
The objective of the invention is to: a kind of mechanical device of removing gear-hobbing burr is provided, utilizes this device in gear hobbing, to remove gear and go out the gear-hobbing burr that produces on the knife face, thereby enhance productivity, reduce production costs.
The present invention constitutes like this: an end of sliding bar (6) is connected with unhairing knife (7), and the other end of sliding bar (6) inserts in the interstitial hole of pedestal (1), flange (4), and flange (4) is connected with pedestal (1).
The shaft shoulder (9) is arranged on sliding bar (6), and spring (3) is enclosed within on the sliding bar (6), and two ends lean against respectively on the endoporus step of the shaft shoulder (9) and pedestal (1).
Sliding bar (6) stretches out the outer end outer circle diameter of pedestal (1) upwards a square hole, and unhairing knife (7) is installed in the square hole; And the axial thread hole is arranged, dress housing screw (8) in the screwed hole is to guarantee the fixed-site of unhairing knife (7).
Axially have groove on the one end cylindrical of sliding bar (6) insertion pedestal (1), anti-turn screw (2) is connected with pedestal (1), and withstands in the groove of sliding bar (6), to guarantee sliding bar (6) fixed-site in a circumferential direction.
Flange (4) is connected with pedestal (1) by attachment screw (5).
The extension elongation of unhairing knife (7) can be adjusted as required.When adjusting the extension elongation of unhairing knife (7) if desired or changing unhairing knife (7), need unclamp housing screw (8); After adjusting or changing, housing screw (8) is tightened got final product again.
The present invention is such deburring:
When the A face of gear is gear hobbing hobboing cutter go out knife face, the A face will produce gear-hobbing burr during gear hobbing so.In order to remove the gear-hobbing burr that the A face produces, the present invention need be installed on the pedestal of gear-hobbing machine, perhaps be installed on the post of gear-hobbing machine.
Owing to have 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 (7) energy unhairing, need accomplish 2 points simultaneously: 1, unhairing knife (7) will be close to going out on the knife face A face of workpiece all the time; 2, unhairing knife (7) with respect to workpiece go out knife face A face, to have one to upward pressure all the time.The present invention accomplishes like this: when the design flexibility knife rest, what make that the installation site of the unhairing knife (7) on the Elastic tool post is higher than workpiece goes out knife face A face certain distance, thereby utilize the elastic force effect of spring (3), both guaranteed that unhairing knife (7) was close to going out on the knife face A face of workpiece all the time, guaranteed that again unhairing knife (7) has one to upward pressure with respect to going out of workpiece the knife face A face all the time, thereby guaranteed that unhairing knife (7) can remove burr.
The present invention removes burr in gear hobbing: because the unhairing knife (7) 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 (7), 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 (7) is just removed burr; If burr turns over into teeth groove, hobboing cutter its cutting edge in gear hobbing burr that will turn over teeth groove is into removed clean so.
Need to prove: Figure 2 shows that a type gear part, the present invention is equally applicable to dish-type type gear part.Because the difference of axle type gear and dish-type type gear part, they are slightly different at the installation way that rolls on the bed when only being gear hobbing.
Because the present invention utilizes the unhairing knife (7) on the Elastic tool post 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.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is installed in position view on the gear-hobbing machine pedestal for the present invention;
Fig. 3 is installed in position view on the gear-hobbing machine post for the present invention.
The specific embodiment:
Embodiments of the invention: make parts such as pedestal 1, spring 3, flange 4, sliding bar 6, unhairing knife 7, assemble according to shown in Figure 1.At first, insert pedestal 1 together after being enclosed within spring 3 on the sliding bar 6, the two ends of spring 3 lean against respectively on the endoporus step of the shaft shoulder 9 and pedestal 1, anti-turn screw 2 is screwed in pedestals 1 and hold out against in the groove of sliding bar 6; Then, with attachment screw 5 flange 4 is connected with pedestal 1; At last, unhairing knife 7 is inserted in the square hole of sliding bar 6, adjust the extension elongation of unhairing knife 7, with housing screw 8 fixing getting final product.
During use, the present invention is fixed on the gear-hobbing machine, what make that unhairing knife 7 is adjacent to workpiece goes out knife face A face, and unhairing knife 7 can be removed burr in the time of gear hobbing.
