Description

The revolving body clamp for machining

Technical field

The utility model relates to a kind of revolving body Special Fixture for Machining, is specifically related to the revolving body Special Fixture for Machining that a kind of convenience loaded and unloaded and changed machined surface fast.

Background technology

Existing flexible gear beveler special purpose spring anchor clamps are installed on the rotating main body of lathe, its revolving body Special Fixture for Machining, and primary structure comprises the orientational cone-shaped surface and the groove at two ends, the centre is revolving body gear mounting portion, conical surface protective sleeve etc.Elder generation takes away protective sleeve when changing the outfit workpiece, from the conical surface whole anchor clamps is taken off to change the outfit again.The shortcoming of this anchor clamps is: the two ends orientational cone-shaped surface is long, adds the length of protective sleeve, wasting space; Workman's operating distance is far away, is unfavorable for operation; Whole anchor clamps quality is big, and labor strength is big, inefficiency; And, retained part precision prescribed height, cost height.

The utility model content

At the prior art above shortcomings, the purpose of this utility model provides the fast revolving body Special Fixture for Machining of loading and unloading and transposing machined surface of a kind of convenience, with reduce cost, reduce working strength of workers, improve space availability ratio, the raising working (machining) efficiency is a purpose.

The purpose of this utility model is achieved in that the revolving body clamp for machining, comprises that the termination is provided with the rotating main body of keyway and boss, is characterized in that:

Between the root of rotating main body termination and the main body male cone (strobilus masculinus) is arranged, radially be provided with a through hole on the male cone (strobilus masculinus); The other end of rotating main body has boss, and boss is provided with inner bolt hole;

The pin of transmission moment of torsion and the through hole interference fit on the rotating main body are arranged;

Frock sleeve with the rotating main body matched in clearance is arranged, and frock sleeve two ends are provided with the inner conical surface that cooperates with described male cone (strobilus masculinus), and radially are provided with the U-shaped mouth that convenient pin inserts, and it cooperates the transmission moment of torsion with pin on the rotating main body; The nut that the both ends of frock sleeve also are provided with external screw thread and cooperate with it.

If the opening pad cooperates with the boss of rotating main body, connect in the rotating main body end by screw and inner bolt hole.

The utility model proposes a unprecedented brand-new jig Design, get rid of the existing problem of prior art, compared to existing technology, have following advantage and useful effect:

1, the symmetry up and down of frock sleeve has guaranteed that it can change machined surface soon, greatly facilitates loading and unloading revolving body and transposing machined surface.

2, kinetoplast and the separately design of frock body, not only alleviated the weight of loading and unloading workpiece body, and the distance of the operating surface that furthers, bring great convenience to the operator.

3, adopt the design of pin and U-shaped mouth, moment is passed the frock sleeve by pin and U-shaped oral instructions, has reduced the pretightning force of lock-screw, has reduced labour intensity, has improved production efficiency.

4, whole clamp structure is simple, and is with low cost.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As depicted in figs. 1 and 2, the utility model revolving body clamp for machining, comprise and be used for the rotating main body 4 that is connected with the lathe rotating shaft, rotating main body 4 terminations are provided with keyway 1 and the platform 2 that the lathe rotating shaft cooperates, between the termination root of rotating main body 4 and the main body male cone (strobilus masculinus) 14 is arranged, the cone angle of male cone (strobilus masculinus) 14 is approximately 60 degree better; Male cone (strobilus masculinus) 14 positions radially are provided with a through hole 3, are provided with pin 13 in the through hole 3, pin 13 and through hole 3 interference fit.The other end of rotating main body 4 is a boss 5, and is provided with inner bolt hole 8; If an opening pad 6 cooperates with the groove 5 of rotating main body 4, connect in the end of rotating main body 4 by screw 7 and inner bolt hole 8.

As shown in Figure 3, be frock sleeve 9, it is used for and rotating main body 4 matched in clearance, and frock sleeve 9 two ends are respectively equipped with the inner conical surface 12 that cooperates with the male cone (strobilus masculinus) 14 of rotating main body 4, and radially are provided with U-shaped mouth 11; The nut 8 that the two ends of frock sleeve 9 also are provided with external screw thread and cooperate with it, nut 8 is used to lock processing work 16; Reach is to be advisable about 25mm.

Referring to Fig. 4, when using the utility model, can earlier revolving body workpieces 16 (as gear) be installed on the frock sleeve 9, two ends cooperate its clamping with external screw thread 15 with nut 10; Then, frock sleeve 9 is sheathed on the rotating main body 4, the U-shaped mouth 11 on the frock sleeve 9 is corresponding with pin 13, is about to sell 13 and penetrates in the U-shaped mouth 11, and by the U-shaped oral instructions torque delivery of pin 13 and frock sleeve 9, moment is passed to frock sleeve 9 by pin 13; Simultaneously, the inner conical surface 12 of frock sleeve 9 and rotating main body 4 male cone (strobilus masculinus)s 14 have cooperated guiding and centering effect, guarantee the axiality of rotating main body 4 and frock sleeve 9; At last, opening pad 6 is inserted from groove 5, tighten lock-screw 7, so just reduced the pretightning force of lock-screw, reduced labour intensity, improved production efficiency.

During clamping, frock sleeve 9 and revolving body 16 are enclosed within on the rotating shaft together, only need become flexible lock-screw 7 during the transposing machined surface, extract opening pad 6 out, take off the frock sleeve 9 that workpiece is housed, change the other end and insert on the rotating main body 4, the operation during repeated clamping gets final product again.As long as unloading operation repeats to change the first half operation of machined surface like this, both reduced labour intensity, improved operating efficiency again.
