Abstract

The utility model discloses an internal-expansion positioning drill holder, composed of an expansion sleeve, a spring, a taper block, a key, a drill template, a pad and a nut which are sheathed on the taper spinder in turn. The expansion sleeve is a round thin-wall tube, two ends of an inner hole are respectively arranged with a taper hole outwards while the center is provided with a cylinder hole, and the wall of the taper hole is provided with 2-8 axial open slots. The utility model uses clearance fit between the expansion sleeve and the inner hole of work-piece, screws the nut to lift up and the taper spindle, via the taper match to expand the expansion sleeve outwards to realize radial positioning, and press the bottom end of the drill template with the object end, and when releases the nut, the taper spindle and the taper block via the spring are released from the expansion sleeve, to return the expansion sleeve, and the work-piece can be taken off. The utility model has accurate position, high machining accuracy, and the application for drilling end of tubular element.

Description

Internal expanding tightening position drill jig

Technical field

The utility model relates to a kind of machining fixture, particularly a kind of brill clamp for machining.

Background technology

The semiaxis bevel gear is to work one of gear that turns to differential in the automobile differential, one transverse plane of its no umbrella tooth is provided with the axial hole that cooperates with lock pin, the existing form accuracy in this hole requires to have again position accuracy demand, prior art cooperates location processing with the bushing plate endoporus with semiaxis bevel gear outside cylinder, this is simple in structure, clamping is easy, still, this location benchmark and design basis disunity, the hole site precision that processes is relatively poor, can not satisfy the icon required precision, causes when using defect such as noise is big.

The utility model content

The utility model is primarily aimed at the deficiencies in the prior art, and proposing a kind of serves as the internal expanding tightening position drill jig of location benchmark with the workpiece to be machined endoporus, and bushing plate in these anchor clamps location benchmark and design basis coincide, accurate positioning, simple in structure, machining accuracy is high.

For achieving the above object, the utility model is taked following technical scheme.

Internal expanding tightening position drill jig, it is made of bushing plate, pad, nut, key, tapering slide block, the core retainer plate that rises, tapering mandrel and spring.Rise core retainer plate, spring, tapering slide block, key, bushing plate, pad and nut of suit successively on the described tapering mandrel.The described core retainer plate that rises is a kind of circular light-wall pipe, and its external diameter is coaxial with endoporus, and the endoporus two ends are respectively equipped with tapered hole outwardly, and the centre is a cylindrical hole, all establishes 2~8 shaft orientation opening grooves on the tapering hole wall.

Cooperate with the workpiece to be machined endoporus with the core retainer plate that rises in the said structure, screw nut,, the core retainer plate that rises is risen outward realize and the radial location of workpiece to be machined endoporus, simultaneously the bushing plate bottom face is combined with processed end face and compress by taper fit with carrying on the tapering mandrel.Otherwise, unclamping nut, tapering mandrel and tapering slide block are thrown off from the core retainer plate that rises under the effect of spring, make the matched in clearance state that rises between core retainer plate recovery and the workpiece, are convenient to workpiece and take out.

The utility model compared with prior art, maximum characteristics be the location benchmark of bushing plate with consistent by the design basis of workpiece, accurate positioning, machining accuracy height, crudy unanimity.

Description of drawings

Fig. 1 is the structural representation of the utility model internal expanding tightening position drill jig.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing is the embodiment that uses one group of lockpin hole on the utility model internal expanding tightening position drill jig processing semiaxis bevel gear one transverse plane.The utility model internal expanding tightening position drill jig is by the core retainer plate 6 that rises, spring 8, tapering slide block 5, key 4, bushing plate 1, pad 2 and the nut 3 of suit constitute jointly successively on the tapering mandrel 7.The described core retainer plate 6 that rises is a kind of circular light-wall pipes made from steel alloy, and hardness is HBS260~320 after the bulk heat treatmet, and preferred value is 290~300.Its external diameter is coaxial with endoporus, and the endoporus two ends are respectively equipped with tapered hole outwardly, and the centre is a cylindrical hole, and tapered hole is 7: 24, all establish 6 shaft orientation opening grooves on the tapering hole wall, groove width 1mm.The internal expanding tightening position drill jig of said structure is cooperated with the work piece endoporus with the core retainer plate 6 that rises, screwing nut 3 will carry on the tapering mandrel 7, by taper fit core retainer plate 6 outer the rising of rising are realized and the radial location of processing work endoporus, simultaneously bushing plate 1 bottom face and processed end joined are compressed, realize bushing plate 1 and workpiece coaxial positioning, after the process finishing, unclamp nut 3, tapering mandrel 7 and tapering slide block 5 are thrown off from the core retainer plate 6 that rises under the effect of spring 8, the core retainer plate 6 that rises is returned to and workpiece between the matched in clearance state, be convenient to workpiece and take out.Drill jig location, the utility model internal expanding tightening position benchmark is consistent with the design basis of work piece, accurate positioning, machining accuracy height, crudy high conformity.
