Description
One, technical field
The utility model relates to a kind of electronic gear grinding machines.
Two, background technology
Along with machined development, sawing machine because of its efficiently operating efficiency begun to be used widely, but when sawing machine work, sawtooth had wearing and tearing, its operating efficiency decline of the sawtooth after the wearing and tearing.
Adopt new sawtooth sheet production cost to increase, what adopt now all is cognate to be processed again make it sharp so that make it be reused for production.
The general structure more complicated of existing gear grinding machines, automatically the roll flute effect is bad.
Three, summary of the invention
The utility model provides a kind of electronic gear grinding machines at above weak point, and that this electronic gear grinding machines have is simple in structure, roll flute efficient and effective advantage.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of electronic gear grinding machines, comprise frame, frame is provided with power set, power set are connected with reciprocating apparatus, described reciprocating apparatus comprises two eccentric wheels that are connected with power set---go up eccentric wheel and following eccentric wheel, wherein the output shaft of power set connects eccentric wheel down, and following eccentric wheel connects by joint pin goes up eccentric wheel; Joint pin is hinged with first connecting rod, and the other end of first connecting rod is hinged with second connecting rod, the other end hinged securement of second connecting rod; Go up eccentric upper end and be hinged with third connecting rod, the other end of third connecting rod is hinged with the 4th connecting rod, the other end hinged securement of the 4th connecting rod; Be fixed with moving tooth bar and electric grinder on second connecting rod and the 4th connecting rod, described moving tooth bar hinged securement, the moving tooth bar be provided with elastic mechanism; Described frame is provided with the sawtooth hold-down mechanism.
Above-mentioned gear grinding machines, the end of described moving tooth bar is provided with roller, the jaggies that contacts with roller be cut in outward roller and with the roller axis normal.
Above-mentioned gear grinding machines, described sawtooth hold-down mechanism comprises two pinch rollers, pinch rollers and serrated face are tangent.
Above-mentioned gear grinding machines, described pinch rollers are the multidiameter shape, and it reduces direction towards the sawtooth direction for the multidiameter diameter.
Above-mentioned gear grinding machines, hinged securement has the moving tooth bar on the described second connecting rod, is fixed with garter spring on the moving tooth bar, and the other end of garter spring is fixed; Be fixed with electric grinder on the 4th connecting rod.
The beneficial effects of the utility model show:
The utility model adopts two eccentric wheels, and two eccentric wheels are interconnected on one, and is simple in structure.Be connected with two cover connecting rods respectively with two eccentric wheels, this two covers connecting rod can be realized moving back and forth, wherein the second connecting rod hinged securement of a cover connecting rod is connected with the moving tooth bar, the second connecting rod of another set of connecting rod is fixed with electric grinder, the reciprocating motion of two cover mechanisms is motion at interval, i.e. in the time of abrasive machine feeding emery wheel, the moving tooth bar is motionless, abrasive machine moved backward after abrasive machine had ground, and the moving tooth bar is stirred sawtooth.
The roller hold-down mechanism that is provided with can be well fixing sawtooth, the multidiameter that is provided with simultaneously can hold out against sawtooth the situation of moving behind the abrasive machine feeding sawtooth can not occur.
The poke rod front end is provided with roller, the jaggies that contacts with roller be cut in outward roller and with the roller axis normal, during the poke rod handsetting gear, sliding friction becomes rolling friction, coefficient of friction diminishes, and the wearing and tearing of poke rod are diminished, and has guaranteed efficiently roll flute operation fast.
Four, description of drawings
Fig. 1 is the utility model reciprocating structure schematic diagram;
Fig. 2 is a utility model plan structure schematic diagram.
Five, the specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
A kind of electronic gear grinding machines comprise frame, and frame is provided with power set, and power set are connected with reciprocating apparatus.
As shown in Figure 1, 2, described reciprocating apparatus comprises two eccentric wheels that are connected with power set---go up eccentric wheel 3 and following eccentric wheel 4.
Upper and lower eccentric installation is as follows: the output shaft of power set connects eccentric wheel 2 down, and following eccentric wheel 2 connects by joint pin 3 goes up eccentric wheel 4; Joint pin 3 is hinged with first connecting rod 6, and the other end of first connecting rod 6 is hinged with second connecting rod 7, the other end hinged securement of second connecting rod 7; The upper end of last eccentric wheel 4 is hinged with third connecting rod 5, and the other end of third connecting rod 5 is hinged with the other end hinged securement of the 4th connecting rod 8, the four connecting rods 8.
Hinged securement has moving tooth bar 10 on the second connecting rod 7, second connecting rod 7 is provided with garter spring 9 with moving tooth bar 10, one end of garter spring 9 is articulated on the moving tooth bar 10, the other end is articulated on the second connecting rod 7, wherein second connecting rod 7 is seen with garter spring 9 and is provided with screens mechanism, so that the location of moving tooth bar 10 and garter spring 9.
Be fixed with electric grinder 12 on the 4th connecting rod 8, described electric grinder 12 is adjustable fixedlying connected with the 4th connecting rod 8, so that adjust the angle of emery wheel and sawtooth.
Described frame is provided with the sawtooth hold-down mechanism, and described sawtooth hold-down mechanism comprises two pinch rollers, and pinch rollers and serrated face are tangent,
When preventing that electric grinder from feeding, the sawtooth work of moving backward to roll flute is made troubles, and pinch rollers is designed to the multidiameter shape, and it reduces direction towards the sawtooth direction for the multidiameter diameter.
The end of described moving tooth bar 10 is provided with roller 11, and jaggies is cut in roller 11 outward.
During use, the sawtooth pressure is located under two pinch rollers of sawtooth hold-down mechanism, is started the motor 1 and the abrasive machine 12 of electronic gear grinding machines, the beginning roll flute gets final product.
During roll flute, moving tooth bar 10 is back and forth stirred sawtooth 13 at interval, and back and forth in the interval procedure, the abrasive machine reciprocating feed has reached the effect of roll flute.
