Description
Technical field
The present invention relates to a kind of fraise jig, especially a kind of tooling of CNC milling machine processing sprocket wheel.
Background technique
Traditionally, the processing of sprocket wheel generally should first mill sprocket, then process key on slotting machine after marking on slab
Slot.In production, it is more demanding such as to encounter sprocket position degree, by traditional handicraft arrangement, reprocesses keyway after sprocket need to have been milled, by
It is curved surface in the sprocket flank of tooth processed, brings difficulty to the centering of marking on slab and slotting machine process, it is difficult to guarantee product quality.
Summary of the invention
In order to solve the above processing difficulties, change traditional handicraft, in each portion's size of the complete sprocket wheel of lathe smart car and marking on slab
Afterwards, first slotting keyway is required up to figure on slotting machine, the then milling sprocket on CNC milling machine, and production miller work through the invention
Dress is to guarantee processing quality.When processing sprocket in view of milling machine, such as with keyway centering, since the every side of keyway is too short, centering is positioned
Difficult and positioning accuracy is difficult to ensure, therefore designs mandrel as shown in Figure 1, makes to become to pass through mandrel to the keyway centering of sprocket wheel
Position the centering on side.And fraise jig as shown in Figure 2 is devised on this basis.
The beneficial effects of the present invention are: the configuration of the present invention is simple, easy to operate, solve in sprocket wheel processing and require a tooth
The problem that must be aligned with key slot center line of center line considerably reduce sprocket wheel especially during mass production
Preparatory process in process is effectively guaranteed while improving product guarantor's processing efficiency and has demonstrate,proved product processing quality.

Specific embodiment
A kind of fixture of CNC milling machine processing sprocket wheel, by base plate 1, the first positioning baffle 2 and the second positioning baffle 3, puts down
Key 13, mandrel 11 and presser device composition.
First positioning baffle 2 and the second positioning baffle 3 are detachably secured on base plate 1 and in 1 planes of base plate
It is inside in 90 ° of arrangements, it is described to be detachably fixed preferably hexagon socket head cap screw connection.
11 lower end of mandrel is positioning end, is equipped with curl 8 and positioning side 7, the length on the positioning side 7 and positioning baffle 3
While being close to, 8 external cylindrical surface of curl and the long side of positioning baffle 2 are close to.Mandrel 11 passes through presser device and base plate 1 after having good positioning
It is detachably connected；
11 upper end of mandrel is fixing end, and for cylinder, diameter is corresponding with the inner hole of required workpieces processing, between formation
Gap cooperation, cylindrical surface are equipped with keyway 10, can be fixed by flat key 13 with workpiece.
The processing for focusing on mandrel 11 of the fixture.The positioning end of the mandrel 11 and the periphery of fixing end need lathe
Processing is completed in clamped one time, positioning side 7 and keyway 10 will complete in the clamped one time of same milling machine process, by lathe
The machining accuracy of geometric accuracy guarantee mandrel.
The presser device can be there are two types of form, the first is that T-bolt 6 is passed through end pressing plate 5 and lower end screw hole phase
Even, the T-type of bolt, which emits, to be pressed on pressing plate, by the elastic of T-bolt, adjusts the pressure of pressing plate；Second is by stud 9
Across center pressing plate 12,9 upper end of stud is equipped with nut 14, and nut can be pressed on center pressing plate 12, by the elastic of nut,
Adjust the pressure of pressing plate；Type bolt 6 described above, end pressing plate 5, stud 9, center pressing plate 12 are example name, former
Manage identical, two kinds of forms can be converted mutually；If pressing plate tightly needs one end to compress, such as end pressing plate 5, cushion block 4 can be placed in the other end,
To guarantee to compress effect.
When installation, on fixing end external cylindrical surface that the bore placement being arranged on sprocket wheel workpiece is arranged on mandrel 11, chain
Wheel workpiece is connected with mandrel 11 by key 13, and the two is joined together to form assembly by presser device.On base plate 1
It is provided with the first positioning baffle 2 and 3. first positioning baffle 2 of the second positioning baffle and the second positioning baffle 3 passes through presser device
It realizes connected with base plate 1.Sprocket wheel and mandrel component are placed on base plate 1, and the positioning side 7 being arranged on mandrel 11 is close to
The long side of positioning baffle 3, the long side of 8 periphery of curl of mandrel 11 against positioning baffle 2.
In the fixture installation process, it need to guarantee that the long side of positioning baffle 3 is parallel with milling machine table X coordinate direction, work as core
When positioning side on axis 11 is close to the long side of positioning baffle 3, since keyway 10 is vertical with the face A on mandrel 11, and key on mandrel 11
Slot is connected by key together with keyway on sprocket wheel again, while again since mandrel 11 is in processing, by technological measure, well
It ensure that the verticality of keyway Yu the basis face A, so, steering sprocket key groove center line and milling machine table X-coordinate direction are hung down at this time
Straight degree requires available guarantee.
After processing a workpiece, which is removed together with mandrel 11, reinstalls next workpiece, quickly
After positioning, it is not necessary to again to knife, can directly be subject to previous sprocket wheel to knife point, processing of directly debugging, this is just greatlyd save
Processing non-cutting time.
The configuration of the present invention is simple, it is easy to operate, it solves and requires the center line of a tooth necessary in sprocket wheel processing and keyway
The problem of center line alignment, ensure that product quality.
Term used herein is explanation and exemplary, term and not restrictive.Since the present invention can be with a variety of
Form be embodied without departing from invention spirit or essence, it should therefore be appreciated that above-described embodiment be not limited to it is any above-mentioned
Details, and should widely explaining within the spirit and scope of the appended claims, thus fall into claim or its etc.
Whole change and modification in effect range all should be appended claims and be covered.
