Abstract

The invention relates to a four-claw large pipe chuck which comprises a chuck body and clamping claws. The four-claw large pipe chuck is characterized by also comprising a wire coil, a gear, the clamping claws, first sliding seats, second sliding seats, stop blocks and lead screws, wherein the wire coil is fixed in the cavity of the chuck body and is connected with the gear through screws; the four clamping claws are respectively connected with four sliding seats; the four lead screws are respectively arranged in the four sliding seats and are located by the stop blocks; the four clamping claws are respectively engaged with the threads on the four lead screws through bottom threads and are respectively installed above the four sliding seats; and the four sliding seats are respectively engaged with the wire coil in a thread mode. The rotation of the gear can drive the wire coil to rotate, the plane motion of the entire sliding seats is realized, and self-centering clamping is completed. The self-centering clamping is completed by controlling the rotation of the gear, and single-action clamping can also be completed by individually operating the lead screws. The clamping means of the chuck is greatly enriched, processing technic is simplified, and labor intensity is reduced.

Description

The large-scale pipe chuck of four paws
Technical field
The present invention relates to the large-scale pipe chuck of a kind of four paws, specifically be used for large-scale pipe use for machining parts frock.
Background technology
Large-scale pipe class workpiece needs the self-centering clamping man-hour sometimes adding, and the automatic centering heart is to simplify processing; Sometimes need the clamping of four paws single action, to improve the bearing capacity of anchor clamps.Existing pipe chuck lacks the compound clamping means of effective with multiple simplifying clamp method, and during machining large pipe class part, chuck clamping means are single, and clamping range is little, needs manual operations, and working (machining) efficiency is low.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of four paws large-scale pipe chuck ,After corresponding gear ring engagement on the machine tool chief axis, can clamp automatically by automatically controlled realization, do not need manual operations, improve working (machining) efficiency greatly, reduced labour intensity.
According to technical scheme provided by the invention, the large-scale pipe chuck of four paws comprises chuck body, claw, and feature is: also comprise parcel, gear, claw, first slide, second slide, reach the 3rd slide, the 4th cunning, block, leading screw; Parcel is fixed in the chuck body inner chamber, be connected with gear by screw, four claws are connected by slide I-shaped groove with first slide, second slide and the 3rd slide, the 4th slide respectively, four rhizoid bars are separately positioned in first slide, second slide and the 3rd slide, the 4th slide, by four block location, screw thread is made at four rhizoid bar two respectively, four claws mesh with four rhizoid bars respectively by bottom thread, and are loaded on first slide, second slide and the 3rd slide, the 4th slide top; First slide, second slide and the 3rd slide, the 4th slide respectively with the parcel screw-threaded engagement.
Described first slide, second slide and the 3rd slide, the 4th slide bottom are provided with flat thread.
Described parcel is provided with the corresponding flat thread of flat thread with described first slide, second slide and the 3rd slide, the 4th slide bottom.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Chuck body adopts the large through-hole design, satisfies the pipe process requirements; Gear rotates and can drive the parcel rotation, thereby realizes the plane motion of slide integral body, finishes the self-centering clamping; Slide can be operated screw mandrel wherein again separately, realizes the single action clamping; Both can rotate and finish the self-centering clamping, and can operate screw mandrel again separately and finish the single action clamping, greatly enrich the clamping means of chuck, simplify processing technology, reduce labour intensity by control gear.
Description of drawings
Fig. 1 is structure master's cutaway view of the present invention.
Fig. 2 is a structure 45 cutaway view of the present invention.
Fig. 3 is the front view of chuck body of the present invention.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1～shown in Figure 2: comprise chuck body 1, parcel 2, gear 4, copper sheathing 5, back-up ring 6, cover plate 7,8, four claws of pad 9, first slide 10, second slide 11, four blocks 12, four rhizoid thick sticks 13, the 3rd slide 14, the 4th slide 15 etc.
Gear 4 of the present invention is set in the rear portion of described chuck body 1, and is fastening by screw with parcel 2.Parcel 2 is fixed in chuck body 1 inner chamber, is connected with gear 4 by screw.Back-up ring 6 and bore interference fit are installed in the gear 4, play position-limiting action.Copper sheathing 5 and back-up ring endoporus interference fit are installed in the back-up ring 6, cooperate installation with machine tool chief axis, play a part to prevent to wear and tear.Be provided with oil groove in the copper sheathing 5, be convenient to lubricate.Pad 8 is installed on the slide top, connects with screw, plays the effect of similar oil sealing.Cover plate 7 usefulness screws are installed in the top of pad 8, play the effect of blocking.Four claws 9 are connected by slide I-shaped groove with first slide 10, second slide 11 and the 3rd slide 14, the 4th slide 15 respectively, four rhizoid bars 13 are separately positioned in first slide 10, second slide 11 and the 3rd slide 14, the 4th slide 15, by four blocks, 12 location, screw thread is made at four rhizoid bars, 13 two respectively, four claws 9 by bottom thread respectively with four rhizoid bars 13 on screw-threaded engagement, and be loaded on first slide 10, second slide 11 and the 3rd slide 14, the 4th slide 15 tops; First slide 10, second slide 11 and the 3rd slide 14, the 4th slide 15 bottoms are provided with flat thread, respectively with parcel 2 respective planes screw-threaded engagement.
Gear 4 of the present invention rotates and can drive parcel 2 rotations, thereby realizes the plane motion of slide integral body, finishes the self-centering clamping; Slide can be operated screw mandrel wherein again separately, realizes the single action clamping.
