Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of position-limit mechanism for scroll chuck, particularly relate to a kind of Digit Control Machine Tool workpiece mechanism.
Background technology
Scroll chuck is made up of chuck body, movable jaw and claw driving mechanism.On scroll chuck below three claw targeting parts, screw thread is had to be meshed with the flat thread at the dish bevel gear back side, when rotating cone pinion with spanner by four square holes, dish pinion rotation, the flat thread at the back side drives three claws close to center simultaneously or exits, in order to clamp the workpiece of different-diameter.It is used on three claws and changes three anti-pawls, be used for the workpiece being relatively large in diameter is installed.When processing work, it is necessary to axially positioning workpiece, in prior art, the stopping means of location is arranged on the center push-pull bar of hydraulic pressure three-jaw, and three-jaw is in clamping or release process.Stopping means together with time move, need operative employee to exert oneself pushing tow workpiece during clamping, positioning precision is relatively low, when unclamping, because of spacing together with time move, the abrasion of three-jaw clamping face is than very fast.
In order to overcome the deficiencies in the prior art, people have passed through continuous exploration, propose various solution, as Chinese patent literature discloses a kind of scroll chuck [application number: CN103273101A], it includes chuck body, drives the device of chuck body rotation, claw driving mechanism and driven the multiple claws clamping or opening by claw driving mechanism；Described chuck body and being driven with clamping or multiple claws of opening for two sets by claw driving mechanism, and two set chuck body coaxial lines are installed, described claw driving mechanism is a set of, and overlaps claws with two and connect with Tong Bus driving；Two described set chuck bodies are arranged in frame through bearing, and are connected with the device driving chuck body to rotate.
Such scheme has two sets due to chuck body, and workpiece is placed on chuck body, claw can be made to clamp two diverse locations on axis of workpiece by claw driving mechanism, it is possible to more stable clamping workpiece.But the program does not have axial positioning function, when unclamping workpiece, workpiece still can be axially moveable, it is necessary to manually holds out against, spacing inconvenience.
Summary of the invention
It is an object of the invention to for the problems referred to above, it is provided that a kind of simple in construction, spacing convenience, the Digit Control Machine Tool workpiece mechanism in scroll chuck service life can be improved.
For reaching above-mentioned purpose, present invention employs following technical proposal: a kind of Digit Control Machine Tool workpiece mechanism, including scroll chuck, described scroll chuck is connected to an oild chuck, it is provided with in described oild chuck and fixes that be connected and that workpiece can be inserted limit fixed sleeve with oild chuck, when workpiece is inserted in limit fixed sleeve, scroll chuck energy clamping or unclamp workpiece, the axial line of axial line and scroll chuck that described limit fixed sleeve has female thread and limit fixed sleeve overlaps, it is bolted with one in limit fixed sleeve and there is externally threaded set screw, described set screw can moving along limit fixed sleeve axially back and forth.
In above-mentioned Digit Control Machine Tool workpiece mechanism, described set screw has dug at least one locking hole, fill out in described locking hole and be provided with a latch segment matched with the shape of locking hole, size, latch segment is provided with the female thread corresponding with limit fixed sleeve, described set screw is provided with at least one latch segment connecting hole connected with locking hole near the end face of scroll chuck, is provided with bolt and this bolt is spirally connected latch segment in described latch segment connecting hole.
In above-mentioned Digit Control Machine Tool workpiece mechanism, described set screw is additionally provided with several screw holes connected with locking hole on the end face of scroll chuck, is provided with and holds out against screw and hold out against screw and latch segment close contact in described screw hole.
Compared with prior art, it is an advantage of the current invention that: 1, during clamping workpiece, workpiece is limited not to be moved, easy to use；2, simple in construction, when changing different products, spacing easy to adjust reliably；3, owing to workpiece is not axially moving, the clamping face of scroll chuck is difficult to wear and tear, and improves the service life of scroll chuck, and set screw can realize stationary state in process of production, improves the precision of work pieces process.

In figure: scroll chuck 10, oild chuck 20, limit fixed sleeve 21, set screw 30, locking hole 31, latch segment 32, latch segment connecting hole 33, screw hole 34.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As depicted in figs. 1 and 2, a kind of Digit Control Machine Tool workpiece mechanism, including scroll chuck 10, described scroll chuck 10 is connected to an oild chuck 20, fixing with oild chuck 20 that be connected and that workpiece can be inserted limit fixed sleeve 21 it is provided with in described oild chuck 20, when workpiece is inserted in limit fixed sleeve 21, scroll chuck 10 can clamping or unclamp workpiece, the axial line of axial line and scroll chuck 10 that described limit fixed sleeve 21 has female thread and limit fixed sleeve 21 overlaps, it is bolted with one in limit fixed sleeve 21 and there is externally threaded set screw 30, described set screw 30 can moving along limit fixed sleeve 21 axially back and forth.
When workpiece is inserted in limit fixed sleeve 21, workpiece and set screw 30 hold out against, the position of set screw 30 can be passed through to rotate thus adjusting the distance at oild chuck 20 at limit fixed sleeve 21, to adapt to the workpiece of different length, distance between set screw 30 and scroll chuck 10 is fixed range during work pieces process, workpiece is fixed along the axial distance of workpiece, will not offset.
Set screw 30 has dug at least one locking hole 31, fill out in described locking hole 31 be provided with one with the shape of locking hole 31, the latch segment 32 that size matches, described set screw 30 is provided with at least one latch segment connecting hole 33 connected with locking hole 31 near the end face of scroll chuck 10, it is provided with bolt in described latch segment connecting hole 33 and this bolt is spirally connected latch segment 32, namely when latch segment 32 is filled in locking hole 31, fix with set screw 30 and be connected, latch segment 32 is provided with the female thread corresponding with limit fixed sleeve 21, latch segment 32 limits set screw 30 movement in the axial direction when bolt-locking, make set screw 30 fixing in limit fixed sleeve 21, preferably, set screw 30 is additionally provided with several screw holes 34 connected with locking hole 31 on the end face of scroll chuck 10, it is provided with in described screw hole 34 to hold out against screw and hold out against screw and is in close contact with latch segment 32, the effect holding out against screw is further fixed locking block 32, namely make set screw 30 and limit fixed sleeve 21 affixed further.
