Description
Technical field
The utility model relates to clamping tool for machine work, particularly a kind of large gear finish turning automatic fixture device.
Background technology
At present, in the processing of large cylindrical tooth, generally adopt micro-axis of cone to carry out turning.Because micro-axis of cone cannot realize axial location, and all only have by artificial swelling at every turn, add quality also larger, handling are got up very inconvenient, and working strength is large, and efficiency is not high yet.
Utility model content
Existing large cylindrical gear conventionally adopts micro-axis of cone location in car or mill processing, and each clamping all needs tool setting, takes a lot of work, time-consuming when production in enormous quantities, and production cost is high.In order to address these problems, the utility model provides a kind of large gear finish turning automatic fixture device.
The utility model solves the technical scheme that its technical problem adopts: large gear finish turning automatic fixture device, comprise, can pack the spring expanding sleeve of gear workpieces endoporus into, can pass through hydraulically powered cone bar, copper sheathing, M10 screw, M12 screw, clamp body, terminal pad, clamp body is by six M12 screw attachment terminal pads; Spring expanding sleeve is by four M10 screw attachment clamp bodies, and the endoporus of copper sheathing and clamp body is interference fit; The small end of spring expanding sleeve has for contacting and provide the taper hole of radial direction tension force with cone bar, and spring expanding sleeve offers for expansion set vertically by the groove of distending; Cone bar is connected with fluid pressure drive device.
Spring expanding sleeve is the one of circular hole expansion set or spline expansion sleeve.
Gear workpieces is placed on spring expanding sleeve, bores the clamping of bar control spring expansion set and loosen, and clamp body mainly rises and connects and supporting role.In the time that hydraulic-driven is bored bar to left movement, cone bar forces spring expanding sleeve to swell, and is adjacent on the endoporus of gear workpieces, realizes and clamping.
The end face of gear workpieces is by the end face location of spring expanding sleeve; End face by spring expanding sleeve and endoporus axially and radially position workpiece, only need initial workpiece gear workpieces to carry out tool setting, have avoided repeating debugging.Use middle gear workpiece realized location and clamped by endoporus and end face, make the spring expanding sleeve of corresponding construction and can realize switching workpiece, therefore fixture has more versatility.
This device adopts hydraulic-driven, clamps having stable behavior reliable, simple to operate light.
The beneficial effects of the utility model are, adopt endoporus and spring expanding sleeve end face location, and by hydraulic-driven fixture clamping, reliable and stable, simple to operation, labour intensity is low; Versatility is good, can meet the product of different inner hole structures, avoids repeating debugging, greatly improves working (machining) efficiency.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Fig. 1～Fig. 2, large gear finish turning automatic fixture device, comprises, can pack the spring expanding sleeve 2 of gear workpieces 1 endoporus into, can pass through hydraulically powered cone bar 4, copper sheathing 3, M10 screw 5, M12 screw 6, clamp body 7, terminal pad 8; Clamp body 7 connects terminal pad 8 by six M12 screws 6; Spring expanding sleeve 2 is by four M10 screw 5 connecting clamp bodies 7, and the endoporus of copper sheathing 3 and clamp body 7 is interference fit; The small end of spring expanding sleeve 2 has for contacting and provide the taper hole of radial direction tension force with cone bar 4, in the time that cone bar 4 moves to 2 one of spring expanding sleeves tension force in the radial direction, thereby swelling gear workpieces 1; Spring expanding sleeve 2 offers is vertically convenient to expansion set by the groove of distending, and cone bar 4 is connected with fluid pressure drive device; Spring expanding sleeve 2 cone bar 4 drive under by distending, by endoporus swelling gear workpieces 1.
In implementation process, gear workpieces 1 is placed on spring expanding sleeve 2, bores the clamping of bar 4 control spring expansion sets 2 and loosen, and main the rising of clamp body 7 connects and supporting role.The end face of gear workpieces 1 is by the end face of spring expanding sleeve 2, and the end face by spring expanding sleeve 2 and inner hole of workpiece axially and radially position workpiece, and initial workpiece workpiece is carried out to tool setting.
In the time that hydraulic-driven is bored bar 4 to left movement, cone bar 4 forces spring expanding sleeve 2 to swell, and is adjacent on the endoporus of gear workpieces 1, realizes and clamping; Gear workpieces 1 is realized location and is clamped by endoporus and end face, makes the spring expanding sleeve 2 of corresponding construction and can realize switching workpiece, and therefore fixture has more versatility.
Gear workpieces 1 positions by end face and axle journal, the end face of the end face of spring expanding sleeve 2 and gear workpieces 1 is close to, the axle journal of expansion set 2 and inner hole of workpiece are matched in clearance, so process different workpiece, only needing gear workpieces 1 endoporus and the datum end face of processing is that available this this fixture carries out fine finishining on the whole, only need initial workpiece workpiece to carry out tool setting, avoided repeating debugging.
Cone bar 4 adopts hydraulic-driven, clamps having stable behavior reliable, simple and quick.
This grip device, in the whole course of work, is slip cooperating relationship between cone bar 4 and copper sheathing 3, changes in time copper sheathing 3, ensures to bore the concentricity of bar 4 and spring expanding sleeve 2 with this.
In operation, after each changing shifts, need to detect the end face run-out that is added gear workpieces 1, i.e. fixture commutation, ensures product quality with this, if there is overproof timely adjustment.
