Description
Technical field
The present invention relates to clamp art, especially relate to a kind of gear ring tooth embryo cutting special fixture.
Background technology
The processing of the gear ring of current gear is the annulus that bar bar being wound in spring-like cuts into opening one by one, again open circles boxing is connected into annulus, through operations such as compacting, quenching, cooling, chamferings, make tooth embryo, then tooth embryo is processed into gear through cutting tooth.Because the application of gear is comparatively extensive, especially on automobile, the use amount of gear is comparatively large, and therefore gear needs batch production, or even produces in enormous quantities.
But the manufacture process of gear needs various fixture, fixture is used for fixing processing object in machine-building process, makes processing object occupy correct position and workpiece is reliably clamped, to accept the device of constructing or detecting.Also known as jig.In a broad sense, any operation in technical process, is used for rapidly, installs easily and safely the device of workpiece, all can be described as fixture.Fixture can be divided into five classes by specialization classification, and the first kind is universal fixturing, and Equations of The Second Kind is special fixture, and the 3rd class is general flexible jig and modular fixture, and the 4th class is built-up jig, and the 5th class is pallet.Universal fixturing refers to standardized, and can be used for the fixture processing different workpieces within the specific limits, advantage is wide adaptability, but production efficiency is low, is mainly applicable in the production of single-piece, small lot, inapplicable in production in enormous quantities.Special fixture refers to certain procedure and custom-designed fixture of aiming at a certain workpiece.
The fixture of existing clamping spring-like workpiece has and is applicable to the workpiece that specification fixed by clamping, along with increase or the reduction of workpiece, need change different fixtures, because the fixture had is heavier, installing/dismounting gets up more complicated, and this strengthens work difficulty with regard to increasing working time, causes operating efficiency lower.
Summary of the invention
The technical problem to be solved in the present invention is: be applicable in order to the fixture overcoming existing clamping spring-like workpiece has the problem that the workpiece of specification fixed by clamping, provides a kind of gear ring tooth embryo to cut special fixture.
The technical solution adopted for the present invention to solve the technical problems is: a kind of gear ring tooth embryo cutting special fixture, comprise base, fastener and hold down gag, described base upper surface is obliquely installed, described fastener is fixedly mounted on base upper surface, and described hold down gag is slidably mounted on base upper surface;
Described fastener comprises scroll chuck and blade, and described blade is fixedly mounted on the claw of scroll chuck, utilizes clamping scroll chuck installed blade to realize to different radii workpiece.
Described hold down gag comprises base, two screws, baffle plate and two nuts, described base is provided with guide runner, the nut portion of described two screws is all slidably mounted in guide runner, described two screws lay respectively at the both sides of scroll chuck, described barrier slides is set on two screws, described two nuts respectively screw thread are arranged on screw, when the workpiece radius of processing is different, can be controlled the maximum compression distance of hold down gag by the position of adjustment screw in guide runner.
Because baffle plate needs workpiece pressing, described baffle length is greater than fastener maximum grip diameter of work, the conveniently movement of screw in guide runner, and described baffle plate upper surface has kidney ellipsoid through hole.
Because the radius of workpiece is different, when carrying out cutting, the workpiece height of small radii can be less than the height of base upper surface, cut in order to avoid when cutting together with base, described base upper surface is provided with opening, described open centre line overlaps with the center line of scroll chuck, and opening provides space to cutter.
Before workpiece is cut, workpiece is enclosed within blade, starting scroll chuck makes three blade all touch workpiece, and by workpiece stretching, the screw of scroll chuck both sides is slided into and absorption surface, baffle-plate-sleeve is located on two screws, two nuts are spun on respectively on two screws, the nut of turn both sides, to baffle plate workpiece pressing, clamping completes.After work pieces process completes, successively unload lower nut and baffle plate, start scroll chuck, loosen workpiece, then the workpiece of well cutting is unloaded, so repeatedly.
The invention has the beneficial effects as follows: the present invention can be suitable for the workpiece of different size, avoid the drawback changing fixture, make processing more simple, convenient, decrease working time and labour cost, improve labor productivity.

Fig. 2 is the scheme of installation of the present invention and workpiece;
Fig. 3 is left view of the present invention;
Fig. 4 is the schematic three dimensional views of baffle plate of the present invention.
In figure: 1. base, 2. scroll chuck, 3. blade, 4. screw, 5. baffle plate, 6. nut, 7. guide runner, 8. workpiece, 9. kidney ellipsoid through hole, 10. opening.
Detailed description of the invention
The present invention will be further described in detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The universal spring-like workpiece 8 of one as shown in Figure 1, Figure 3 fixture, comprises base 1, fastener and hold down gag, and base 1 upper surface is obliquely installed, and fastener is fixedly mounted on base 1 upper surface, and hold down gag is slidably mounted on base 1 upper surface;
Fastener comprises scroll chuck 2 and blade 3, and blade 3 is fixedly mounted on the claw of scroll chuck 2, utilizes clamping scroll chuck 2 installed blade 3 and realize different radii workpiece 8.
Hold down gag comprises base 1, two screws 4, baffle plate 5 and two nuts 6, base 1 is provided with guide runner 7, the nut portion of two screws 4 is all slidably mounted in guide runner 7, two screws 4 lay respectively at the both sides of scroll chuck 2, baffle plate 5 is slidably located on two screws 4 as shown in Figure 4, two nuts 6 respectively screw thread are arranged on screw 4, when workpiece 8 radius processed is different, can be controlled the maximum compression distance of hold down gag by the position of adjustment screw 4 in guide runner 7.
Because baffle plate 5 needs workpiece pressing 8, baffle plate 5 length is greater than fastener maximum grip workpiece 8 diameter, the conveniently movement of screw 4 in guide runner 7, and baffle plate 5 upper surface has kidney ellipsoid through hole 9.
Because the radius of workpiece 8 is different, when carrying out cutting, workpiece 8 height of small radii can be less than the height of base 1 upper surface, cut in order to avoid when cutting together with base 1, base 1 upper surface is provided with opening 10, opening 10 center line overlaps with the center line of scroll chuck 2, and opening 10 provides space to cutter.
As shown in Figure 2, before workpiece 8 is cut, workpiece 8 is enclosed within blade 3, starts scroll chuck 2 and make three blade 3 all touch workpiece 8, and by workpiece 8 stretching, the screw 4 of scroll chuck 2 both sides is slided into and contacts with workpiece 8, baffle plate 5 is set on two screws 4, two nuts 6 is spun on respectively on two screws 4, the nut 6 of turn both sides, to baffle plate 5 workpiece pressing 8, clamping completes.After workpiece 8 machines, successively unload lower nut 6 and baffle plate 5, start scroll chuck 2, loosen workpiece 8, then the workpiece 8 of well cutting is unloaded, so repeatedly.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
