Description

Interchangeable, fine-tuning thin slice presss from both sides outer circle clamp

Technical field

The utility model belongs to technology and pattern assembly scope, more particularly to a kind of to be suitable for umbilicate type soldered tooth turning flange excircle Interchangeable, fine-tuning thin slice press from both sides outer circle clamp.

Background technology

Umbilicate type soldered tooth in automobile gearbox, teeth portion are recessed in ring gear slot.Its teeth portion generally use warm forging（Heat Forging）+ cold-forging forming（Finishing squeezes down cone）Combined precision forging and forming technology produces.In order to ensure that the flank of tooth is smaller after back taper Circular runout, need to be after the finishing flank of tooth, clip tooth outer circle vehicle flange large cylindrical（On the basis of the additional circle of tooth）, then squeeze down cone.

Vehicle flange excircle common practice is, on lathe three-claw self-centering chuck, the soft pawl of clamping, from the soft pawl endoporus of boring to Tooth outside diameter.Due to the limitation of umbilicate type ring gear slot space, the retained part in soft pawl can only be not only short but also thin thin slice, thick Degree only has 3mm or so.

See Fig. 1, is common soft pawl clamping schematic diagram.

In mass production, because soft pawl hardness itself is low, abrasion is more, so that clamp precision reduces, is producing For Cheng Zhongxu often again from the clamping thin slice in the soft pawl of boring, each boring all vehicles fall the surplus of sheet thickness 0.3mm.In this way from boring It cuts several times, sheet segment is just scrapped, and a whole set of soft pawl is caused to cancel.

The shortcomings that above method is：The thickness that thin slice is clamped is small, and soft pawl hardness is low, not wear-resisting, needs often again from boring, Whole soft pawl short life, cost are higher；And often replace soft pawl and re-calibrate, influence production efficiency.

Invention content

The purpose of the utility model is to overcome defects of the existing technology, provide a kind of suitable for umbilicate type soldered tooth vehicle Cut interchangeable, the fine-tuning thin slice folder outer circle clamp of flange excircle.

Realizing the technical solution of the utility model aim is：A kind of interchangeable, fine-tuning thin slice folder outer circle clamp, has Soft pawl ontology and the thin slice that the tooth outer circle for clamping umbilicate type soldered tooth is bolted to by first；The soft pawl ontology tool There are three, and connect with the three-jaw self-centering chuck on lathe by corresponding second bolt, three soft this physical efficiencys of pawl are simultaneously It shrinks or loosens to axle center；The outer circle of the thin slice connects with the four adjustable adjusting bolts connected on each soft pawl ontology It touches.

The section of thin slice described in above-mentioned technical proposal is L-shaped.

Thin slice described in above-mentioned technical proposal is integrated thin rounded flakes or is made of the arc thin slice of the arc length such as three.

After adopting the above technical scheme, the utility model have the effect of it is following positive：

（1）The utility model is suitable for the fixture of umbilicate type soldered tooth turning flange excircle, by soft pawl ontology and thin slice two Part forms.

（2）The utility model works as thin slice bore wear, when clamp precision declines, it is not necessary to again from boring thin slice, be adjusted four A adjusting bolt finely tunes the outer circle of thin slice, makes up the wear extent of thin slice endoporus, to maintain clamp precision, thin slice service life to improve More, cost is relatively low, and production efficiency is higher；When thin slice abrasion reaches capacity the service life, replaceable new thin slice, it is not necessary to replace soft Pawl ontology, cost are relatively low.

（3）The utility model can manufacture the thin slice of different-diameter, the umbilicate type soldered tooth outer circle of clamping different model, in this way It is fast to change production speed, production efficiency height.

Specific implementation mode

（Embodiment 1）

See that Fig. 3 to Fig. 7, the utility model are a kind of interchangeable, fine-tuning thin slice folder outer circle clamp, there is soft pawl ontology 1 and the thin slice 2 of the tooth outer circle for clamping umbilicate type soldered tooth is connected to by the first bolt 3；The soft pawl ontology 1 has three It is a, and connect with the three-jaw self-centering chuck on lathe by corresponding second bolt 4, three soft pawl ontologies 1 can simultaneously to Axle center is shunk or is loosened, and Self-centering Action is played；Four connected in the outer circle of the thin slice 2 and each soft pawl ontology 1 are adjustable Adjusting bolt 5 be in contact.

The section of thin slice 2 is L-shaped.

Thin slice 2 is integrated thin rounded flakes 2 or is made of the arc thin slice 2 of the arc length such as three.

The operation principle of the utility model is：When 2 bore wear of thin slice, when clamp precision declines, it is not necessary to again thin from boring Four adjusting bolts 5 are adjusted in piece 2, finely tune the outer circle of thin slice 2, make up the wear extent of 2 endoporus of thin slice, to maintain fixture smart Degree, the raising of 2 service life of thin slice is more, and cost is relatively low, and production efficiency is higher；It is replaceable new when the abrasion of thin slice 2 reaches capacity the service life Thin slice 2, it is not necessary to replace soft pawl ontology 1, cost is relatively low.

Particular embodiments described above has carried out into one the purpose of this utility model, technical solution and advantageous effect Step is described in detail, it should be understood that the foregoing is merely specific embodiment of the utility model, is not limited to this Utility model, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done should all wrap Containing being within the protection scope of the utility model.
