Abstract
The invention discloses a novel mechanism of a composite center. The mechanism consists of an adjusting screw, a sleeve, a disk spring, a locking nut, a deadlock center, a positioning center and a sharp tooth, wherein the composite center with a clamping function is provided with the positioning center; the positioning center is arranged in an inner hole of the sleeve and has degree of freedom for axial movement in the sleeve; the disk spring is arranged in the sleeve on the rear part of the positioning center; the adjusting screw and the sleeve are arranged together in a threaded matching mode; the deadlock center is arranged at the left end of the sleeve in a threaded matching mode; the positioning center can extend out of an intermediate hole of the deadlock center for a certain length; the locking nut is arranged on the threads of an external circular part at the left end of the sleeve; and after a certain pre-compression force is produced to the disk spring by the adjusting screw, the deadlock center is tightened by using the locking nut.
Description
Technical field
The present invention relates to a kind of compound top mechanism, the top mechanism of particularly a kind of new type compound belongs to Metal Cutting Machine Tool attachment technique field.
Background technology
Top is critical function parts in the Metal Cutting Machine Tool, and it generally is installed in the tail stock sleeve in lathe, or is installed in simultaneously in the spindle hole of barrel of tail stock and lathe; No matter it takes which kind of mounting means on lathe, and its main function has been exactly the effect of centralized positioning, in the process of processing with clamp workpiece such as chuck or heart carriers, so that transmit power in the cutting.Because existing top function with location, so, clamp at work with the location and must carry out respectively, when working shaft-like part in enormous quantities, clamping work pieces is a pretty troublesome job of also losing time, and has reduced the efficient that work is produced to a certain extent.
Summary of the invention
The objective of the invention is to: provide a kind of new type compound top mechanism, this compound top function that had both had centralized positioning, have clamping work pieces simultaneously, transmit the function of cutting power, overcome existing top owing to only have that single positioning function brings: the location with clamp and must carry out respectively, and the scarce limit of the reduction labor productivity that causes thus.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: the mechanism that a kind of new type compound is top, it is by reconciling screw, sleeve, disk spring, lock nut, locked top, locate top, pointed tooth is formed, clamping the compound top of function has a location top, locate in the top endoporus that is installed in sleeve, locate the top axially movable free degree that in sleeve, has, in the sleeve at top rear portion, location, one dish-shaped spring is installed, mode and the sleeve of adjustment screw by threaded engagement is installed together, locked top mode by threaded engagement is installed in the left end of sleeve, and locate and toply can in locked top interstitial hole, stretch out certain length, on the screw thread of the left end cylindrical of sleeve, one lock nut is installed, adjustment screw, after adjustment screw produces certain pre-pressing force to disk spring, with lock nut and tight locked top.
Operation principle of the present invention is: above-mentioned installation all-in-one-piece is compound top, cylindrical by compound tailstock sleeve is fixed in the spindle hole or barrel of tail stock of lathe, locating top center center hole with workpiece positions, when the top axial pressing force of further adjusting, top axial pressing force is greater than disk spring elastic force, so, top just mobile backward, the end face certain depth that thrusts workpiece up to the sharp pointed tooth of locked top end face just begins to stop, at this moment, the sharp pointed tooth of locked top end face thrusts the end face of workpiece, make workpiece and locked top becoming one, so, realize by top location, the function of locked top transferring power; This kind be compound toply to be suitable for especially that cutting output is less, the processing of the workpiece in enormous quantities in fine finishining and the grinding class technology.
Beneficial effect: when the present invention works, the compound top function that had both had centralized positioning, have clamping work pieces simultaneously, transmit the function of cutting power, overcome existing top owing to only have that single positioning function brings: the location with clamp and must carry out respectively, and the scarce limit of the reduction labor productivity that causes thus.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further;
Fig. 1 is a structure principle chart of the present invention;
Shown in the figure: 1, reconcile screw; 2, sleeve; 3, disk spring; 4, lock nut; 5, locked top; 6, the location is top; A, pointed tooth.
Specific implementation method
Clamping the compound top of function has one to locate top (6), locating top (6) is installed in the endoporus of sleeve (2), locate top (6) and in sleeve (2), have the axially movable free degree, in the sleeve at top (6) rear portion, location, one dish-shaped spring (3) is installed, mode and the sleeve (2) of adjustment screw (1) by threaded engagement is installed together, locked top (5) are installed in the left end of sleeve (2) by the mode of threaded engagement, and locate top (6) and can in the interstitial hole of locked top (5), stretch out certain length, on the screw thread of the left end cylindrical of sleeve (2), one lock nut (4) is installed, adjustment screw (1), after adjustment screw (1) produces certain pre-pressing force to disk spring (3), with lock nut (4) and tight locked top (5).
Claims (2)
1. mechanism that new type compound is top, it is characterized in that: locate top (6) and be installed in the endoporus of sleeve (2), locate top (6) and in sleeve (2), have the axially movable free degree, in the sleeve at top (6) rear portion, location, a dish-shaped spring (3) is installed.
2. according to the top mechanism of claims 1 described a kind of new type compound, it is characterized in that: mode and the sleeve (2) of adjustment screw (1) by threaded engagement is installed together, locked top (5) are installed in the left end of sleeve (2) by the mode of threaded engagement, and locate top (6) and can in the interstitial hole of locked top (5), stretch out certain length, on the screw thread of the left end cylindrical of sleeve (2), one lock nut (4) is installed, adjustment screw (1), after adjustment screw (1) produces certain pre-pressing force to disk spring (3), with lock nut (4) and tight locked top (5).
