The utility model adopts pneumatic control and has the advantages that the structure is simple, the operation is convenient and rapid, and greatly improves the working accuracy of the production.
Description
Technical field
The utility model relates to a kind of Metal Cutting Machine Tool annex, particularly relates to a kind of aerodynamic center frame with compressed air-driven.It is suitable for using on lathe miscellaneous or the numerically controlled lathe; Also can use on the Metal Cutting Machine Tool that is matched in other.
Background technology
At present, the application of numerically controlled lathe in machine-building is quite universal, but still adopts common manual centre frame to realize supporting longaxones parts on the lathe bed of numerically controlled lathe at processing longaxones parts majority on the numerically controlled lathe.Because the setting accuracy of described manual centre frame is lower, operation and use trouble, location efficiency is not high again, can not be satisfied with supporting use on all kinds of numerically controlled lathes.
Summary of the invention
The purpose of this utility model provides a kind of aerodynamic center frame pneumatic control, simple in structure and convenient to operation that adopts.
The purpose of this utility model is by providing a kind of a kind of aerodynamic center frame with following structure to realize, it comprises a center stand that is connected with bed piece, slide and be provided with along the circumferential direction uniform last loose piece, left loose piece and right loose piece in the top of center stand, last loose piece, left loose piece can contact with the periphery of a shaft-like workpiece jointly with the top of right loose piece; Be connected with screw rod respectively on the described left and right loose piece, described center stand is provided with the lock-screw that two left and right loose pieces of locking are used; The described loose piece of going up is connected with a piston rod that can drive the cylinder of its action.
The described front end of going up loose piece, left loose piece, right loose piece also can respectively be provided with a bearing, and bearing all contacts with the periphery of described workpiece.
Also can be provided with the breach of being convenient to work-handling on the stand of described center.
Compared with prior art, advantage of the present utility model is: 1. improve the machining accuracy of workpiece, radially runout can reach 0.005～0.012 millimeter; 2. workpiece loading and unloading is convenient, thereby enhances productivity; 3. be matched in the automatic control that can realize workpiece loading and unloading on the Digit Control Machine Tool; 4. manufacture craft is simple and easy, and production cost is lower.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side direction partial view of left loose piece and right loose piece;
The specific embodiment
Embodiment describes in further detail utility model below in conjunction with accompanying drawing.
Fig. 1 shows an embodiment of the utility model aerodynamic center frame.It comprises the center stand 10 of a band support plate 12 that is connected with bed piece 11.
Stand 10 tops in center are provided with that slidably to go up loose piece 4, left loose piece 2 and 3, three loose pieces of right loose piece along the circumferential direction uniform with 120 ° of intervals, the outer surface of last loose piece 4, left loose piece 2, the top together support workpiece 6 of right loose piece 3 after regulating.Wherein on left and right loose piece, be bolted with a screw rod 8,9 respectively, drive loose piece separately by screw rod and move, to adjust the exact position of left and right loose piece supporting workpiece 6 as fore-and-aft direction.Lock-screw 5, two lock-screws 5 that also are provided with two corresponding left and right loose pieces of difference in addition on center stand 10 contact with the circumferential surface of left loose piece 2, right loose piece 3 respectively, are used to locate left loose piece 2, the right loose piece 3 adjusted.
The upper-lower position of last loose piece 4 is regulated by cylinder, and its upper end links to each other with the piston rod of a cylinder 1, and when cylinder piston rod moved down, workpiece clamped and enters processing, and when cylinder piston rod moved up, workpiece unclamped and enters loading and unloading.
And for the worker is rotated flexibly, being provided with a bearing 7 at the front end of last loose piece 4, left loose piece 2, right loose piece 3, bearing 7 peripheries contact with the periphery of workpiece 6.For the ease of work-handling, have a breach 13 on the left side of center stand 10 simultaneously.
The course of work of the utility model aerodynamic center frame is such: at first processed shaft-like workpiece 6 is placed between loose piece 4, left loose piece 2 and the right loose piece 3, the described shaft-like workpiece of a batch need only carry out school sired results preface by unit one, and remaining workpiece must not carry out school sired results preface.After adjusting the correct Support Position of left loose piece 2, right loose piece 3 and the outer surface of workpiece 6 then, be locked with lock-screw 5.Then, cylinder 1 is started in operation, goes up loose piece 4 by the cylinder drive and moves down, and workpiece 6 is clamped, but enter machining state.If will loosen workpiece 6, the piston rod of cylinder is moved up, workpiece 6 can be unclamped, can load and unload.
The utility model aerodynamic center frame is matched in the automatic control that can realize workpiece loading and unloading on the Digit Control Machine Tool; Can improve simultaneously the machining accuracy of workpiece, the radially runout of processing work can reach 0.005～0.012 millimeter.
