Abstract
The utility model discloses an automatic tool changing device for bevel gear working machine, comprising a turntable tool magazine that can move along an axial line and can turn around, the clamping and uncoupling gear of the facing cutter, the indexing mechanism of the turntable tool magazine, the location mechanism of the turntable tool magazine, a positioning and torque transmission device of the facing cutter on a cutter spindle and on an anti-rotary mechanism of the facing cutter the turntable tool magazine. The device sufficiently considers the request of high accuracy and big moment of torque of the milling and can be applied to a digital control bevel gear cutting machine, and the multi-procedure process such as the rough cutting and the fine cutting of the concave, the fine cutting of the convex surface, etc., by a spiral bevel gear on one machine tool with one time clamping, can be realized.
Description
The automatic tool changer of bevel gear cutting machine is used for bevel gear cutting machine, and it can satisfy high accuracy, high efficiency, the automatic tool changer processing of bevel gear.
Bevel gear is used very extensive in machine driving, it particularly in automobile, tractor and traveling vehicle indispensable part, still occupy most fields according to the circular arc line tooth system bevel gear of Gleason (GLEASON) and the extension epicycloidal tooth system bevel gear of Ao Likang (OERLIKON) in the world at present, the circular arc line tooth system bevel gear of making based on Gleason (GLEASON) again in China.Processing to this bevel gear, the gear cutting machine that adopts conventional method is because the complexity of its adjustment, usually a pair of gear need be finished with 5 lathes, rough lumber, the concave surface essence that is driving wheel (steamboat) cut, the convex surface essence is cut, the rough lumber of follower (bull wheel), smart grain, owing to constantly changed machine tooling by cut spare, produce following shortcoming:
1, gear is repeatedly located, and has increased alignment error, has influenced machining accuracy.
2, workpiece multiple conversions lathe has increased process flow, has reduced operating efficiency, has increased labour intensity.
3, owing to use lathe more, one-time investment is bigger, and the place takies bigger.
4, because multiple operation is processed the beat difference, be difficult to reach the balance of production capacity, make the equipment component live load not full.
U.S.'s Gleason (GLEASON) company has developed the 5-shaft linkage numerical control bevel gear cutting machine at present, and the adjustment of lathe is greatly simplified, but lathe still is hilted broadsword processing, and different operations still need be finished on different lathes.Hu Erte (HURTH) company of Germany has also developed the 5-shaft linkage numerical control bevel gear cutting machine of double-pole tool main shaft, can finish duplexing preface production, but owing to adopt double-pole tool main shaft to make the machine tool structure complexity, has limited the range of work of lathe.
In sum, also do not have a kind of bevel gear cutting machine that can realize automatic tool changer, multiple operation processing at present, also do not adopt the present invention in the heart in the various cutter-exchange mechanisms that work in-process uses.
The utility model aims to provide a kind of automatic tool changer that is used for the numerical control bevel gear machining tool, can realize operations such as rough lumber, concave surface essence that bevel gear is finished steamboat at a machine tool, clamping are cut, the convex surface essence is cut.
The utility model comprises a rotating disk tool magazine that three facing cutters can be installed, and the rotating disk storehouse is by the tool changing campaign of moving and realize along the revolution of the axis of controlling oneself facing cutter along the axis of cutter spindle.
The automatic tool changer of bevel gear cutting machine should possess very high facing cutter and repeat centering precision and high in conjunction with rigidity.Location and the torque-transmitting mechanisms of facing cutter of the present invention on cutter spindle can address this problem.At the cutter spindle front end positioning end fluted disc is installed, on each installs the handle of a knife of facing cutter, an end-toothed disc is installed, through precision machined end-toothed disc can obtain very high repetition centering precision and be equal to rigid body in conjunction with rigidity.Along with continuous use break-in, it repeats centering precision and improves in conjunction with rigidity thereupon.
Installing three has bigger quality to the rotating disk tool magazine of facing cutter, its rotary inertia and to turn round amount of unbalance all bigger.And two end-toothed discs require its axis to have higher axiality in cohesive process.The detent mechanism of rotating disk tool magazine of the present invention can eliminate because the error of division that inertia and amount of unbalance cause.The taper bolt that equates with facing cutter quantity is installed on the rotating disk tool magazine, the location tapered sleeve is installed on tool head.When taper pin begins to enter tapered sleeve, both have bigger gap, therefore allow the rotating disk tool magazine that the bigger error of division is arranged, the degree of depth that enters tapered sleeve along with taper pin increases, the gap of taper pin and tapered sleeve reduces, the rotating disk tool magazine will be tending towards the tram, finally can guarantee two end-toothed discs in conjunction with the time, have higher axiality.
When two end-toothed discs were thrown off, facing cutter should be fixed on the rotating disk tool magazine, and bow tie can not be arranged.Otherwise can not guarantee next time two end-toothed discs in conjunction with the time, repeat last time in conjunction with the time phase place, will reduce in conjunction with precision.The rotation preventing mechanism of facing cutter of the present invention on the rotating disk tool magazine can address this problem.On the circumference of the end-toothed disc that the handle of a knife with the installation facing cutter connects mutually, an alignment pin is arranged, one telescopic V-type locating piece is arranged on the rotating disk tool magazine, one push rod is arranged on the housing of cutter spindle front end, end-toothed disc in conjunction with the time, to the rear end, facing cutter can rotate with cutter spindle push rod with V-type locating piece top.When two end-toothed discs were thrown off, push rod and V-type locating piece were thrown off, and the V-type locating piece stretches out, and the V-type groove blocks alignment pin, and facing cutter can not rotate.
The rotating disk tool magazine indexing mechanism that the utility model adopted can better way be realized the dividing movement of rotating disk tool magazine.Dividing movement is by a plunger rack drives, and the revolution of plunger rack drives one gear has splined hole at the center of gear, and the other end of rotating disk tool magazine is a splined shaft; Splined shaft enters in the splined hole automatically when the rotating disk tool magazine lifts, and by the revolution of plunger rack drives rotating disk tool magazine, the angle of revolution is determined by the stroke of plunger tooth bar.Splined shaft withdrawed from from splined hole automatically when the rotating disk tool magazine fell, and the plunger tooth bar resets.
