Description
Technical field
The present invention relates to a kind of preparation method of sprocket tooth form and processing unit (plant).
Background technology
The combination of chain and sprocket wheel is as a kind of drive disk assembly in motorcycle, bicycle and various industrial machineries
In be widely adopted.And its middle sprocket is the core component in equipment, both requires to ensure accuracy, sprocket wheel and chain are required again
Bar hole correct engagement.Generally prepare sprocket wheel to be all processed above with hobboing cutter in gear-hobbing machine, although for processing
During the less standard sprocket of pitch, there are higher processing efficiency, but shadow larger by hobboing cutter sectional dimension in process
Ring, its result is not reached preferable effect.And preparing some specifications than larger, or the processing of nonstandard sprocket wheel when
Wait, hobboing cutter processing in terms of equipment and quantity there is also larger by being limited.Therefore, for batch machining some big specifications chain
Wheel component, some other methods of processing sprocket tooth form are urgently found.
The content of the invention
It is an object of the invention to improve the precision and production efficiency of sprocket wheel, reduction production cost is utilized into there is provided one kind
The sprocket tooth form preparation method and processing unit (plant) of type wire rod quality milling sprocket wheel blank.
The technical scheme is that：
A kind of preparation method of sprocket tooth form, sets molding disc milling cutter above numerical control platform, sets a NC dividing head；Number
Mounting tool fixture on dividing head is controlled, sprocket wheel blank is fixed on NC dividing head, sprocket wheel blank follows NC dividing head to turn
Dynamic, molding disc milling cutter high speed longitudinal direction rotates and dropped to the height of sprocket wheel blank, moves reciprocatingly and completes the preparation of sprocket tooth form.
A kind of device for processing sprocket tooth form, including molding disc milling cutter, sprocket wheel blank and NC dividing head, molding disc milling cutter
It is arranged on above numerical control platform, sprocket wheel blank is fixed on NC dividing head, forming disk by mounting tool fixture on NC dividing head
Milling cutter longitudinally rotates, and drops to sprocket wheel blank height, moves back and forth processing sprocket tooth form.
The technical characteristics of the present invention are that sprocket wheel blank follows NC dividing head to rotate, and molding disc milling cutter milling blank is simultaneously
Move reciprocatingly.The present invention is reasonable in design, because traditional sprocket tooth form preparation method is to fix sprocket wheel blank, slotting cutter according to
Numerical control programming processes workpiece, and processing efficiency is low, and it is very big also to there is when method is programmed amount of calculation, and calculation error is not
Easy to control the problems such as.But the preparation method utilizes molding disc milling cutter milling tooth form, is compared to traditional sprocket tooth form preparation method,
The uniformity between tooth form is ensure that, precision is improved；The sprocket wheel and chain hole correct engagement of preparation can be made again, reduction rubs
Wipe；This method carries out blank milling by molding disc milling cutter simultaneously, longer compared to slotting cutter service life, and simplifies volume
Journey, reduces production cost.
The features of the present invention and have the technical effect that：
The present invention is reasonable in design, because traditional sprocket tooth form preparation method is to fix sprocket wheel blank, slotting cutter is according to number
Control-register journey processes workpiece, and processing efficiency is low, and it is very big also to there is when method is programmed amount of calculation, and calculation error is difficult
The problems such as control.But the preparation method utilizes molding disc milling cutter milling tooth form, is compared to traditional sprocket tooth form preparation method, energy
Enough ensure the uniformity between tooth form, improve precision；The sprocket wheel and chain hole correct engagement of preparation can be made again, friction is reduced；
This method carries out blank milling by molding disc milling cutter simultaneously, longer compared to slotting cutter service life, and simplifies programming, drop
Low production cost.
Brief description of the drawings
Fig. 1 is the overall front view of the present invention.
Embodiment
The present invention is described in further detail below by specific embodiment, following examples be it is descriptive, no
It can be limited the scope of the invention with this.
A kind of preparation method of sprocket tooth form, including molding disc milling cutter 1, NC dividing head 2 and sprocket wheel blank 3；Forming disk
Milling cutter 1 be for milling sprocket wheel blank, using Hardmetal materials, mounting tool fixture on NC dividing head 2, by sprocket wheel blank
It is fixed on NC dividing head, sprocket wheel blank 3 prepares sprocket wheel for molding disc milling cutter milling.Its technical characteristics is chain wheel blank
Part 3 follows NC dividing head 2 to rotate, and longitudinal direction rotates and drops to certain altitude milling blank 3 and do past molding disc milling cutter 1 at a high speed
Multiple motion completes the preparation of sprocket tooth form.The precision and production efficiency of sprocket wheel are improved, production cost is reduced.
The present invention is reasonable in design, because traditional sprocket tooth form preparation method is to fix sprocket wheel blank, slotting cutter is according to number
Control-register journey processes workpiece, and processing efficiency is low, and it is very big also to there is when method is programmed amount of calculation, and calculation error is difficult
The problems such as control.But the preparation method utilizes molding disc milling cutter milling tooth form, is compared to traditional sprocket tooth form preparation method, energy
Enough ensure the uniformity between tooth form, improve precision；The sprocket wheel and chain hole correct engagement of preparation can be made again, friction is reduced；
This method carries out blank milling by molding disc milling cutter simultaneously, longer compared to slotting cutter service life, and simplifies programming, drop
Low production cost.
