Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of position-limit mechanism for scroll chuck, relate in particular 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, there is screw thread to be meshed with the flat thread at the dish-shaped bevel gear back side, in the time rotating cone pinion with spanner by cubic hole, dish gear rotates, the flat thread at the back side drive simultaneously three claws to center near or exit, in order to clamp the workpiece of different-diameter.Be used on three claws and change three anti-pawls, be used for installing the workpiece that diameter is larger.In the time of processing work, need to be to axially the positioning of workpiece, in prior art, the stopping means of location use is arranged on the center pull bar of hydraulic pressure three-jaw, and three-jaw is in clamping or release process.Stopping means together with time move, when clamping, need operative employee's pushing tow workpiece of exerting oneself, positioning precision is relatively low, while unclamping, because of spacing together with time move, the wearing and tearing of three-jaw clamping face are than very fast.
In order to overcome the deficiencies in the prior art, people have passed through continuous exploration, various solutions have been proposed, as Chinese patent literature discloses a kind of scroll chuck [application number: CN103273101A], it comprises device, the claw driving mechanism that chuck body, driver card disk body rotate and is driven the multiple claws that clamp or open by claw driving mechanism; Described chuck body and the multiple claws that drive to clamp or open by claw driving mechanism are two covers, and two cover chuck body coaxial lines installations, and described claw driving mechanism is a set of, and connects and drive to synchronize with two cover claws; Two described cover chuck bodies are arranged in frame through bearing, and the device rotating with driver card disk body is connected.
Such scheme, because chuck body has two covers, is placed on workpiece on chuck body, can make claw clamp two diverse locations on axis of workpiece, clamping work pieces that can be more stable by claw driving mechanism.But this scheme does not have axial positioning function, in the time unclamping workpiece, workpiece still can move vertically, need to manually hold out against spacing inconvenience.
Summary of the invention
The object of the invention is for the problems referred to above, a kind of convenience simple in structure, spacing is provided, can improves the scroll chuck Digit Control Machine Tool workpiece mechanism in service life.
For achieving the above object, the present invention has adopted following technical proposal: a kind of Digit Control Machine Tool workpiece mechanism, comprise scroll chuck, on described scroll chuck, be connected with an oild chuck, in described oild chuck, be provided with the limit fixed sleeve being fixedly connected with oild chuck and can insert workpiece, in workpiece is inserted into limit fixed sleeve time, scroll chuck can clamp or unclamp workpiece, described limit fixed sleeve has the axial line of internal thread and limit fixed sleeve and the axial line of scroll chuck overlaps, in limit fixed sleeve, be bolted with one and there is externally threaded set screw, described set screw can axially moving forward and backward along limit fixed sleeve.
In above-mentioned Digit Control Machine Tool workpiece mechanism, in described set screw, dig at least one locking hole, in described locking hole, fill out be provided with one with the shape of locking hole, the latch segment that size matches, latch segment be provided with limit fixed sleeve with respect to internal thread, described set screw is provided with near the end face of scroll chuck the latch segment connecting hole that at least one is communicated with locking hole, is provided with bolt and this bolt latch segment that is spirally connected in described latch segment connecting hole.
In above-mentioned Digit Control Machine Tool workpiece mechanism, described set screw, near being also provided with the screw hole that several are communicated with locking hole on the end face of scroll chuck, being provided with in described screw hole and holding out against screw and hold out against screw and latch segment close contact.
Compared with prior art, the invention has the advantages that: 1, when holding workpiece, workpiece is limited not to be moved, easy to use; 2, simple in structure, while changing different products, spacing easy to adjust reliable; 3,, because workpiece is not axially moving, the clamping face of scroll chuck is difficult to wearing and tearing, the service life of having improved scroll chuck, and set screw can realize stationary state in process of production, improved the precision of workpiece processing.

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, one Digit Control Machine Tool workpiece mechanism, comprise scroll chuck 10, on described scroll chuck 10, be connected with an oild chuck 20, in described oild chuck 20, be provided with that be fixedly connected with oild chuck 20 and can insert the limit fixed sleeve 21 of workpiece, when workpiece is inserted into limit fixed sleeve 21 when interior, scroll chuck 10 can clamp or unclamp workpiece, the axial line that described limit fixed sleeve 21 has internal thread and limit fixed sleeve 21 overlaps with the axial line of scroll chuck 10, in limit fixed sleeve 21, be bolted with one and there is externally threaded set screw 30, described set screw 30 can axially moving forward and backward along limit fixed sleeve 21.
In the time that workpiece is inserted in limit fixed sleeve 21, workpiece and set screw 30 hold out against, thereby the position of set screw 30 can be by rotating the distance that is adjusted 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 the fixed range that workpiece adds man-hour, workpiece is fixed along the axial distance of workpiece, can not be offset.
