Description
Technical field
The present invention relates to a kind of gear shapping machine part, particularly one kind to be realized inside and outside automatically on gear shapping machine using double cam
Tooth by knife the two-way knife tripper that allows of gear shapping machine.
Background technology
The requirement of gear is machined according to gear shaping, pinion cutter needs one to allow knife to move away from workpiece in backhaul, kept away
Exempt from blunt gear shaping blade during backhaul and scratch machined workpiece surface.Due to the required knife direction phase that allows when processing inside and outside tooth
Instead, swivel is allowed to change into for a technical barrier when gear shaping machines inside and outside tooth, existing relieving mechanism is complicated, and cost is high,
Need to manually it be adjusted during conversion, it is very inconvenient.
Chinese patent CN1861305 discloses a kind of tool retracting conversion device for gear-shaper, and butterfly spring is adjusted by screw
Pine and tight, when impulse stroke, pinion cutter it is positive completely by the large radius common guarantee of two conjugate cams, during return, roller
Disengaged with conjugate cam, cutter shaft is acted on by butterfly spring, pinion cutter is swung an angle and is returned.The problem of existing is that conversion needs
Manually to be adjusted, be not easy realization and automatically control, and allow knife to be realized by the pressure differential of both sides butterfly spring, to butterfly spring
Required precision is higher.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of two-way knife tripper that allows of gear shapping machine, it is ensured that
Realized when gear shaping machines inside and outside tooth and allow knife automatic conversion.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of gear shapping machine is two-way to allow knife from turn
Converting mechanism, including support, tool-post structure are hinged by bearing pin and support, and knife rest bar is arranged in tool-post structure in which can slide axially,
Slider-crank mechanism is hinged with knife rest bar, and the power transmission shaft for driving rotation by drive device is connected with slider-crank mechanism, in knife rest
The side of body is provided with and allows knife roller, and the opposite side of tool-post structure is provided with spring damping；
Power transmission shaft, with allowing cutter shaft to be connected, knife cam and is allowed for first with allowing knife roller is engaged by transmission mechanism
Two, which allow knife cam to be arranged on can sliding axially, allows on cutter shaft, and first allows knife cam and second to allow knife cam with allowing the rotation of cutter shaft
Then rotate, first allows knife cam and second to allow knife cam to be connected with the diverter cylinder for driving it to slide.
In the side for allowing knife roller, conversion allows knife cylinder to be connected with tool-post structure.
Described changing allows knife cylinder and diverter cylinder as oil cylinder or cylinder.
Described first allows knife cam and second to make the lift of knife cam opposite.
Described transmission mechanism is timing belt or gear train.
A kind of gear shapping machine provided by the invention is two-way to allow knife tripper, switches by using diverter cylinder with allowing knife to roll
What son coordinated first allows knife cam and second to allow knife cam, realizes the automatic conversion of inside and outside tooth during gear shaping.Set
Spring damping ensures to allow knife roller to allow with first all the time knife cam or second to allow knife cam contact.The present invention is highly susceptible to realizing certainly
Dynamic control.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the integrally-built schematic diagram of the present invention.
In figure：First timing belt 1, the second timing belt 2, slider-crank mechanism 3, tool-post structure 4 allow knife roller 5, spring damping
6, conversion allows knife cylinder 7, and first allows knife cam 8, diverter cylinder 9, and second allows knife cam 10, allows cutter shaft 11, bearing pin 12, guidance part 13,
Knife rest bar 14, motor 15, support 16, power transmission shaft 17.
Embodiment
In Fig. 1, a kind of gear shapping machine is two-way to allow knife tripper, including support 16, tool-post structure 4 by bearing pin 12 with
Support 16 is be hinged, and knife rest bar 14 is arranged in tool-post structure 4 in which can slide axially, and the cunning of knife rest bar 14 is guided by guidance part 13
It is dynamic.
Slider-crank mechanism 3 is be hinged with knife rest bar 14, i.e., by the rotation of crank, the linear motion with movable knife rack bar 14, by
The power transmission shaft 17 of drive device driving rotation is connected with slider-crank mechanism 3, specifically, motor 15 is driven by the first timing belt 1
Dynamic power transmission shaft 17 rotates.It is provided with the side of tool-post structure 4 and allows knife roller 5, the opposite side of tool-post structure 4 is provided with spring damping 6；
Power transmission shaft 17 by transmission mechanism with allowing cutter shaft 11 to be connected, described transmission mechanism be timing belt or gear train or
Other transmission mechanisms, such as chain-drive mechanism.Knife cam 8 and second is allowed to allow knife for first with allowing knife roller 5 is engaged
Cam 10 is arranged on and allowed on cutter shaft 11 in which can slide axially, and first allows knife cam 8 and second to allow knife cam 10 with allowing cutter shaft 11
Rotation and rotate, first allows knife cam 8 and second to allow knife cam 10 with allowing the connection of the similar spline of connection between cutter shaft 11
Structure.
First allows knife cam 8 and second to allow knife cam 10 to be connected with the diverter cylinder 9 for driving it to slide.By controlling diverter cylinder
9 it is flexible, first allows knife cam 8 and second to allow knife cam 10 to slide allowing on cutter shaft 11, switches and allows matching somebody with somebody between knife roller 5
Close.
In the side for allowing knife roller 5, conversion allows knife cylinder 7 to be connected with tool-post structure 4.Conversion allows the stretching of knife cylinder 7, makes to allow knife to roll
Son 5 allows knife cam 8 and second to allow knife cam 10 to disengage with first.
Described changing allows knife cylinder 7 and diverter cylinder 9 as oil cylinder or cylinder.Oil cylinder is used in this example, because conversion allows knife cylinder 7
It is not high with requirement of the diverter cylinder 9 for precision, therefore it is being easy to the occasion of pneumatic control, such as the occasion with air compressor machine,
Using cylinder and feasible.
Described first allows knife cam 8 and second to make the lift of knife cam 10 opposite.Thus structure, realize during gear shaping it is interior,
The automatic conversion of external tooth.
In use, the first timing belt 1 and the second timing belt 2 ensure that in slider-crank mechanism 3 that crank rotates and allows cutter shaft
11 synchronous axial systems, that is, it ensure that the synchronous progress for allowing knife to be moved up and down with cutter shaft.Spring damping 6, which ensure that, allows knife roller 5 all the time
Knife cam 8 is allowed to contact with first, when processing internal tooth, first allows the lift of knife cam 8 to promote the realization of tool-post structure 4 to insert in cutter backhaul
Serrated knife outwards allows knife, and when processing external tooth, the second pinion cutter when allowing the drop journey of knife cam 10 to realize cutter backhaul inwardly allows knife.
Process internal tooth when, in cutter backhaul first allow knife cam 8 inside and outside tooth change when, conversion allow knife cylinder 7 promote knife rest
Body 4 is displaced outwardly a distance, makes to allow knife roller 5 to allow knife cam 8 to disengage with first, and diverter cylinder 9 promotes cam holder to make second to allow
Knife cam 10 replaces first and allows knife cam 8, and conversion allows the return of knife cylinder 7, spring damping 6 reassured allow knife roller 5 cheat eventually with
Second allows knife cam 10 to contact, and realizes the automatic conversion of inside and outside tooth during gear shaping.
