The fixture solves the problem that a blind hole gear with inclined blind hole internal diameter ring surface and blind hole external diameter ring surface cannot be clamped, and can stably and effectively clamp the blind hole gear; and the product precision is greatly improved.
Description
Technical field
The utility model relates to a kind of anchor clamps that grip gear, relates in particular to the anchor clamps that the Vehicle Processing of a kind of blind hole gear is used.
Background technology
Engage a gear blind hole on the motorcycle blind hole gear is used for the motorcycle engage a gear to be used, and when Vehicle Processing blind hole gear, generally all is to clamp benchmark with the engage a gear blind hole as the location.Existing anchor clamps all are the internal diameter anchor ring or the external diameter anchor rings of clamping blind hole; But a lot of blind hole gears forge difficulty for the intensity of strengthening gear with reducing; Internal diameter anchor ring and external diameter anchor ring to gear have increased bigger gradient; Thereby cause existing anchor clamps not cause machining accuracy lower to internal diameter anchor ring, the effective clamping of external diameter anchor ring of gear.
The utility model content
The technical problem that the utility model solves is: a kind of blind hole gear anchor clamps that Vehicle Processing is used is provided, increased the blind hole gear of bigger gradient for blind hole internal diameter anchor ring and blind hole external diameter anchor ring, and can firmly effective clamping.
The technical scheme of the utility model is: the anchor clamps that the Vehicle Processing of a kind of blind hole gear is used; It is characterized in that; Comprise terminal pad with central through hole and the ringfeder that is fixed on terminal pad one end, said ringfeder comprises that ring flange and equidistance gap ringwise are distributed on three axially extended pressure containing parts on the ring flange, and the outer working face of each pressure containing part all is the tapering inclination; The top of each pressure containing part is equipped with grip block; One draw ring is set on the outer working face of said three pressure containing parts, and said draw ring has and the suitable interior inclined working of the outer working face of pressure containing part, and a pull bar is through in the central through hole of terminal pad; One end and the said draw ring of pull bar fix, and the other end of pull bar is fixed with the attaching nut.
One end vertical fixing of said pull bar has three connecting rods, and each connecting rod passes and fixes with said draw ring the gap between three pressure containing parts respectively.
Said pull bar and each connecting rod are formed in one, and are connected fixing between each connecting rod and the draw ring respectively through bolt.
Said pull bar is a hollow tubular, is connected fixing between pull bar and the said attaching nut through a bolt that is through in the pull bar.
The other end of said terminal pad is provided with the ring flange that is used to connect lathe spindle.
The beneficial effect of the utility model is: the utility model adopts the expansion set clamping mode; The grip block location of ringfeder clamps the muscle rib of blind hole side; The internal diameter anchor ring of existing anchor clamps clamping blind hole gear or the mode of external diameter anchor ring have been changed; Not only having solved can't clamping blind hole internal diameter anchor ring and the gradient blind hole gear of blind hole outer-diameter ring mask, and firmly effectively clamping.Problem has improved the product precision simultaneously greatly.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1～Figure 10; The anchor clamps that the Vehicle Processing of a kind of blind hole gear is used; Comprise terminal pad 1 with central through hole and the ringfeder 2 that is fixed on terminal pad one end; Ringfeder 2 comprise ring flange 21 and ringwise the equidistance gap be distributed on three axially extended pressure containing parts 22 on the ring flange, the outer working face of each pressure containing part 22 all is tapering and tilts, the top of each pressure containing part 22 is equipped with grip block 23; One draw ring 3 is set on the outer working face 22 ' of three pressure containing parts 22, and draw ring 3 has the interior inclined working 3 ' suitable with the outer working face of pressure containing part 22 22 '.Pull bar 4 is through in the central through hole of terminal pad 1, and an end and the draw ring 3 of pull bar 4 fix, and the other end of pull bar 4 is fixed with attaching nut 5; Wherein, One end vertical fixing of pull bar 4 has three connecting rods 4 ', and pull bar 4 is formed in one with each connecting rod 4 ', and each connecting rod 4 ' passes the gap between three pressure containing parts 22 respectively and is connected through bolt with draw ring 3 and fixes; Pull bar 4 is a hollow tubular, is connected fixing between pull bar 4 and the attaching nut 5 through a bolt 6 that is through in the pull bar 4.The other end of terminal pad 1 is provided with the ring flange 1 ' that is used to connect lathe spindle, terminal pad 1 and ring flange 1 ' integrally casting moulding.
The utility model operation principle is:
The ring flange 1 ' of terminal pad is connected through bolt with the ring flange of lathe spindle; Screw rod 7 on attaching nut 5 and the lathe is connected, gives screw rod 7 when cylinder or oil cylinder transferring power, screw rod 7 drives attaching nuts 5; Attaching nut 5 drives pull bar 4; Pull bar 4 drives draw ring 3 to left movement, the outer working face of three pressure containing parts 22 of the interior inclined working extruding expansion set 2 of draw ring 3, and three pressure containing parts 22 of expansion set 2 inwardly shrink in opposite directions; The grip block 23 on three pressure containing part 22 tops clamps the muscle rib 8 ' of the blind hole side of blind hole gear 8, and starting device begins processing.After machining, under cylinder or oil cylinder effect, screw rod 7 drives draw ring 3 and moves right, and expansion set unclamps, thereby unclamps blind hole gear 8.
