Abstract

The invention discloses an externally-tightening and quick-changing hobbing tool for shafts. The externally-tightening and quick-changing hobbing tool comprises a base installed on a work plane of a machine tool. A transition pull plate and an adhesion tightening sleeve are sequentially installed on the base. The transition pull plate is connected to a pull rod of the machine tool and driven by the pull rod of the machine tool to move downwards or upwards. The adhesion tightening sleeve is matched with the transition pull plate to tighten or loosen work-pieces. According to the characteristics that power takeoff shafts are various and production change is frequent, the externally-tightening and quick-changing hobbing tool is designed. According to the tool, serialization design is carried out on the adhesion tightening sleeve and a centre, the adhesion tightening sleeve and the centre are convenient to change, and the design range of clamps for new shaft parts in future can be expanded.

Description

A kind of axle external-expanding type quick change gear hobbing tooling
[technical field]
The invention belongs to Machining Technology field, relate to one and change product instrument, especially a kind of axle external-expanding type quick change gear hobbing tooling.
[background technology]
At present, power takeoff product type is more, and various power takeoff output shaft, hollow shaft are all arranged on same production line and produce, change produce frequency very high.And how inconsistent out-of-alignment cylindrical, length and centre bore location dimension be.Relevant tool between cars on hand is all adopt rigidity ringfeder, and the outside diameter scope that rigidity ringfeder can clamp is little especially, substantially the corresponding sleeve clamp of each part, and handling when changing product, regulation time are very long, affect production line output.
[summary of the invention]
The object of the invention is to the shortcoming overcoming above-mentioned prior art, provide a kind of axle external-expanding type quick change gear hobbing tooling, this frock takes into account the multiple axial workpiece on line, and bonding ringfeder and top being convenient to are changed simultaneously.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of axle external-expanding type quick change gear hobbing tooling, comprises the base be arranged on lathe working face, base is installed successively transition supports, top, transition pulling plate and bonding ringfeder; Transition pulling plate is connected with lathe pull bar by screw fairlead assembly, moves downward or upward under the drive of lathe pull bar; Bonding ringfeder coordinates tensioner with transition pulling plate or unclamps workpiece.
The present invention further improves and is:
Described transition pulling plate is supported by transition and is arranged on base.
Described bonding ringfeder is provided with some along the circumferential direction equally distributed tension points, and expanding force when bonding ringfeder is coordinated with transition pulling plate is more even.
The endoporus that cylindrical and the transition of described transition pulling plate support matches.
Also comprise one and change product aid for changing the top of different size.
Flat structure is cut in described top employing, and supports with transition the part that endoporus matches and arrange for guaranteeing the platform that top center line is vertical with table plane; Top afterbody has been provided with the screw thread of guiding and fixation.
Compared with prior art, the present invention has following beneficial effect:
The present invention according to many according to auxiliary drive shaft veriety, change and produce the feature such as frequent, devise external-expanding type quick change gear hobbing tooling.This frock is to bonding ringfeder and toply carry out Seriation Design, and bonding ringfeder and top being convenient to are changed simultaneously, and the jig Design that this frock increases axial workpiece newly after being simultaneously provides expanding function.
Further, base standard of the present invention, has taken into account the gear hobbing stroke of 32 kinds of axial workpiece 10mm-240mm.
Further, invention increases the scope of ringfeder clamping outside diameter, simultaneously design six tension points on bonding ringfeder, when coordinating with transition pulling plate bonding ringfeder expanding force evenly.
Further, transition pulling plate adopts petal type structure, and cylindrical and transition support endoporus 3 and coordinate, and have both solved fixture internal chip evacuation problem, the guiding problem of transition pulling plate when having taken into account again Workpiece clamping.
Further, flat structure is cut in top employing, and devises and change product aid, for quick-replaceable; Support mating part with transition and increase platform, guarantee that top center line is vertical with table plane; Support endoporus with transition to match, guarantee that installation site is accurate, stable; The helicitic texture of top afterbody plays guiding and fixation.

Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is the structural representation of the bonding ringfeder of the present invention, and wherein (a) is front view, and (b) is side view;
Fig. 3 is the structural representation of transition pulling plate of the present invention, and wherein (a) is side view, and (b) is front view.
Wherein: 1 for changing product aid; 2 is bonding ringfeder; 3 is top; 4 is transition pulling plate; 5 is transition support; 6 is fairlead; 7 is base; 8 is lathe pull bar.
[detailed description of the invention]
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See Fig. 1, the present invention includes the base 7 be arranged on lathe working face, base 7 installed successively transition supports 5, top 3, transition pulling plate 4 and bonding ringfeder 2; In addition, also comprise one for change different size top 3 change produce aid 1; Top 3 adopt and cut flat structure, and support with transition the part that 5 endoporus match and arrange for guaranteeing the platform that top center line is vertical with table plane; The afterbody of top 3 has been provided with the screw thread of guiding and fixation.Transition pulling plate 4 is connected with lathe pull bar 8 with the matable assembly of fairlead 6 by screw, moves downward or upward under the drive of lathe pull bar 8; Bonding ringfeder 2 coordinates tensioner with transition pulling plate 4 or unclamps workpiece.Bonding ringfeder 2 is provided with some along the circumferential direction equally distributed tension points, and expanding force when bonding ringfeder 2 is coordinated with transition pulling plate 4 is more even.Transition pulling plate 4 is fixedly connected with lathe pull bar 8 with the matable assembly of fairlead 6 by screw.Transition pulling plate 4 supports 5 by transition and is arranged on base 7.The endoporus that cylindrical and the transition of transition pulling plate 4 support 5 matches.
The course of work of the present invention:
Be installed on lathe working face by a whole set of frock by base 7, fixture debugging is suitable.During clamping work pieces, machine tool hydraulic cylinder provides power to drive pull bar 8 to move down, screw fairlead 6 assembly be arranged on pull bar 8 drives transition pulling plate 4 to move down, bonding ringfeder 2 rotates to an angle and to coordinate with transition pulling plate 4, move downward together, tensioner workpiece, toply on lathe moves down top tight workpiece, and clamp action completes; When unclamping workpiece, lathe pull bar 8 moves upward, and the screw fairlead 6 being arranged on pull bar 8 drives transition pulling plate 4 and bonding ringfeder 2 to move upward, and bonding ringfeder 2 unclamps, and fixture unclamps action to be completed.
Change top: use is changed product aid 1 and pulled down top 3, changes the top of suitable dimension.
Change bonding ringfeder: taken off by dust cover, being rotated to an angle by bonding ringfeder 2 makes it depart from transition pulling plate 4 to coordinate, then taken off the bonding ringfeder changing suitable size.
Above content is only and technological thought of the present invention is described; protection scope of the present invention can not be limited with this; every technological thought proposed according to the present invention, any change that technical scheme basis is done, within the protection domain all falling into claims of the present invention.
