Abstract
The utility model discloses a transposable end face driving centre of a flexible medium floating finger seat and belongs to the machinery field. According to the transposable end face driving centre of the flexible medium floating finger seat, a guiding element is fixed in a centre body through a plug and a round nut, a disc spring is sleeved on the guiding element and is connected with an ejector pin through a screw, three fingers are installed in the eccentric finger seat which is installed in the centre body, the rotation of the finger seat is restricted by a screw, and flexible media are filled in a left cavity of a piston. According to the transposable end face driving centre of the flexible medium floating finger seat, clamping force of the fingers of the clamp is not restricted by limit speed of a hydraulic cylinder installed at the rear end of a main shaft, and cutting speed is further improved; the fingers can be taken out conveniently for sharpening, and therefore the using range of the clamp is widened; due to the fact that flexible floating medium cavities are communicated, acting force of all fingers on an end face of a workpiece is enabled to be consistent; and the end face driving centre has low requirements for positions of the end face of the workpiece, manufacturing cost is greatly reduced, and therefore market promotion potential is great.
Description
Technical field
The utility model belongs to mechanical field, relates in particular to a kind of flexible media pusher dog seat end face that can replace that floats and drives top.
Background technology
On lathe in processing work, must install with fixture and clip workpiece to be processed, determine that on lathe workpiece applies active force with respect to the tram of cutter to workpiece, make it on the position of having reserved, workpiece to be clamped reliably, the major function of turning attachment is exactly to complete the clamping work of workpiece.Lathe spindle rotating speed increasingly high, to traditional clamp technology, serious challenge has been proposed: no matter be axial workpiece or disk cover parts, after the speed of mainshaft of lathe surpasses certain limit, the limit speed that is installed on the hydraulic cylinder of rear-end of spindle will become the principal element that the restriction cutting speed further improves.Therefore, adopt the end face actuation techniques just to become one of very important developing direction of speed lathe fixture dynamically lower.
Summary of the invention
For the problems referred to above, the utility model provides a kind of flexible media pusher dog seat end face that can replace that floats to drive toply, has solved the problem of restriction cutting speed when machine tool chief axis runs up.
For realizing above purpose, by the following technical solutions:
A kind of flexible media pusher dog seat end face that can replace that floats drives top, comprise top body, plug, director element, dish spring, thimble, flexible media, piston, pusher dog seat, pusher dog, lubricating cup, director element is fixed in top body by plug and round nut, the dish spring is enclosed within on director element, be connected with thimble by screw, three pusher dogs are arranged in eccentric pusher dog seat, and the pusher dog seat is arranged in top body, and limit it by screw and rotate, flexible media in filling in the left chamber of piston.
Described three pusher dogs distribute along even circumferential, can adjust angle, and during work and the end face joint of workpiece trace embeds in it.
The left chamber of described three pistons communicates.
Described flexible media can be steel ball, vaseline, liquid plastics or petroleum base hydraulic oil.
In described lubricating cup, machine oil is housed, is the thimble lubricate.
The beneficial effects of the utility model are: after the speed of mainshaft of lathe surpassed certain limit, the limit speed that the clamping force of this fixture pusher dog is not installed on the hydraulic cylinder of rear-end of spindle restricted, and its cutting speed can be further enhanced.Pusher dog is arranged in eccentric pusher dog seat.After pusher dog wearing and tearing passivation, can take out easily reconditioning, the pusher dog seat than 180 ° of shown position transpositions after, pusher dog will be on a larger-diameter distribution circumference, thereby adapt to the clamping of larger diameter workpiece, enlarge the scope of application of fixture.Owing to having adopted the flexible floating moving medium, and flexible floating moving medium chamber communicates, and the site error of the error of three pusher dog self length dimensions and workpiece end face is carried out compensation in certain limit, and every pusher dog is consistent to the active force of workpiece end face.End face drive top position to workpiece end face degree require extremely lowly, and manufacturing cost significantly descends, therefore, its marketing potentiality are had an optimistic view of very much.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model.
In figure: the top body of 1-; The 2-plug; The 3-round nut; The 4-director element; 5-dish spring; The 6-screw; The 7-thimble; The 8-overcoat; The 9-flexible media; The 10-piston; 11-pusher dog seat; The 12-screw; The 13-holding screw; The 14-pusher dog; The 15-lubricating cup.
The specific embodiment
Further illustrate the utility model below in conjunction with Figure of description.
as shown in the figure, director element (4) is fixed in top body (1) by plug (2) and round nut (3), dish spring (5) is enclosed within on director element (4), be connected with thimble (7) by screw (6), three pusher dogs (14) are fixed on overcoat (8) by holding screw (13), distribute along even circumferential, pusher dog is arranged in eccentric pusher dog seat (11), after pusher dog wearing and tearing passivation, can take out easily reconditioning, pusher dog seat (11) is arranged in top body (l), and limit its rotation by screw (12), after 180 ° of transpositions are clamored in pusher dog seat (1l) position more shown in Figure 1, pusher dog (14) will be on a larger-diameter distribution circumference, thereby the clamping that adapts to the larger diameter workpiece.Flexible media in filling in the left chamber of piston (10), and the left chamber of three pistons (10) communicates, flexible media (9) plays floating action, can carry out the interior compensation of certain limit to the error of pusher dog (14) self length dimension and the site error of workpiece end face.Every pusher dog is consistent to the active force of workpiece end face.Lubricating cup is equipped with machine oil in (15), is the thimble lubricate.
During work, the taper shank of thimble (7) is installed in tapered bore of machine tool spindle, location on workpiece is top in front and back two.When the thrust that overcomes dish spring (5) under the effect of tailstock pressure during to left movement, the right-hand member cutting edge of three pusher dogs (14) just contacts with the left side of workpiece, then trace embeds in it, just drive workpiece rotating after the machine tool chief axis running, and the torque that opposing is caused by cutting force after machining begins.
