Description

A kind of adjustable top clip composite tool

Technical field

The utility model is related to field of mechanical technique, more particularly to one kind to apply in lathe process tubing long or solid shafting class Hold out against processing or drilling, fraising occasion adjustable top clip composite tool.

Background technology

When seamless pipe more long or larger is processed with solid pole, it is required for first in machine tool chief axis Clamp blocks one end, Then the other end of part is held out against with live centre again, machining is carried out to part again after the completion of clamping.Traditional revolution It is top to there is larger defect in structure design, when in use, because vertex of a cone head is too small, it is impossible to withstand pipe slightly bigger Endoporus, be at this moment accomplished by changing big umbellate form revolution and, or the umbellate form cone disk on set on vertex of a cone head, use very Inconvenience, and traditional live centre when pipe endoporus is held out against, it is necessary to first carry out chamfering to pipe endoporus, could hold out against completely in Hole, increased manufacturing procedure and workload, when need to drill part, ream and during the process operation such as tapping, it is necessary to Again drill chuck is changed, the corresponding machining tools such as drill bit or centre drill are clamped, step is various, using inconvenience, reduced and add Work efficiency rate.

Utility model content

For above-mentioned technical problem, the purpose of this utility model be for effectively solve traditional live centre unitary function, Step is various to wait not enough, there is provided a kind of simple structure, the adjustable top clip composite tool of highly versatile.

In order to solve the above technical problems, the technical solution of the utility model is：A kind of adjustable top clip composite tool, including Cone lid, taper shank, chuck and stop pin, the cone lid and taper shank are connected through a screw thread, and pin hole and method are provided with the taper shank Blue disk, is provided with pin-and-hole corresponding with pin hole on the ring flange, the chuck is bolted on ring flange, described Stop pin is inserted in pin hole and in embedded pin-and-hole so that ring flange is locked on taper shank, can be used as drill chuck, stop pin Can extract or insert according to duty requirements.

Preferably, jacking block, thrust ball bearing, the first deep groove ball bearing, spacer, second are disposed with the taper shank deeply Ditch ball bearing and dust cap.

Preferably, the dust cap and taper shank are connected through a screw thread.

Preferably, the chuck is three-jaw self-centering chuck, and different size is adapted to by adjusting the claw size of chuck The pipe of endoporus or solid bar hold out against operation, and chuck can carry out dismounting exclusive use according to the demand of processing operating mode, for machine Bed clamping parts.

Compared with prior art, the beneficial effects of the utility model are：1）When the seamless pipe or solid that processing is more long, larger Rod, will use live centre or revolution umbellate form when taking over a business, and can quickly finish the operation of tail top；2）With heart function is made by oneself, on top After tight pipe, can voluntarily with one heart, without being corrected again with dial gauge；3）Held out against again after chuck is clamped, stress is more preferable, more It is even, the machining accuracy and qualification rate of product can be improved, and without carrying out down drift angle to the pipe for needing top in advance, improve operation Efficiency；4）The pipe or solid bar that different size endoporus is adapted to by adjusting the claw size of chuck hold out against operation, reduce Top use cost；5）Can be used as drill chuck when plugging stop pin, realize that the processing such as drilling, punching to part are grasped Make, it is easy to use.

Specific embodiment

In order that those skilled in the art is better understood from the technical solution of the utility model, below in conjunction with the accompanying drawings to this The technical scheme of utility model is further elaborated.

Embodiment one：When being used as live centre, as shown in Figure 1 and Figure 2, the cone lid 1 and taper shank 2 pass through screw thread Connection, and successively fill jacking block 8, thrust ball bearing 9, the first deep groove ball bearing 10, the deep groove ball bearing 12 of spacer 11 and second Enter taper shank 2, then dust cap 13 is tightened with taper shank 2 by screw thread, allocate into inside ring flange 6 to taper shank 2, chuck 3 is passed through into spiral shell Bolt 14 is locked on ring flange 6, and stop pin 4 pulls away pin-and-hole 7, and claw 31 finally is loaded into chuck 3.By opening for claw 31 Regulation square hole 15 is closed, the opening and closing of claw 31 are adjusted, to be applied to clamp internal diameter pipe of different sizes, the effect of holding out against is played, will be bored Handle 2 is inserted in tailstock tool, and claw 31 clamps cylindrical or stretching endoporus, completes pipe and holds out against, when the tail for needing to use different size During seat, only need that the mohs bush of different model first is inserted in into taper shank, tailstock tool is then inserted in again；When processing part is solid bar When, square hole 15 is adjusted by the opening and closing of claw 31, adjust the opening and closing of claw 31, the clamping cone of claw 31 top 16, in holding out against solid bar Heart hole.

Embodiment two：When being used as drill chuck, as shown in Figure 1, Figure 3, the cone lid 1 and taper shank 2 are connected by screw thread Connect, and successively load jacking block 8, thrust ball bearing 9, the first deep groove ball bearing 10, the deep groove ball bearing 12 of spacer 11 and second Taper shank 2, then dust cap 13 is tightened with taper shank 2 by screw thread, allocate into inside ring flange 6 to taper shank 2, chuck 3 is passed through into bolt 14 are locked on ring flange 6, stop pin 4 is inserted in pin hole 5 and in embedded pin-and-hole 7, claw 31 finally is loaded into card Disk 3, when needing to drill part, centering, fraising or during tapping, need to only adjust the opening and closing of claw 31, clamp drill bit, in Heart brill, reamer or screw tap etc., corresponding process operation is carried out to part.

The utility model according to duty requirements can be selected as live centre or drill chuck is used, highly versatile, user Just, with self-centering and clamping function, and without carrying out down drift angle to the pipe for needing top in advance, processing efficiency is fast, while Reduce the use cost of production and processing aid.

The above is the utility model preferably implementation method, in the case of the utility model design is not departed from, is carried out Any obvious deformation and replacement, belong to protection domain of the present utility model.
