Abstract
The invention relates to a strong composite center. The strong composite center is arranged in an inner hole of a sleeve through a positioning center; liquid plastic is filled in the sleeve; a plug and the sleeve are arranged together; the left end face of a locking center is provided with a sharp tooth which protrudes the end face; the locking center is arranged at the left end of the sleeve; the positioning center positions a workpiece through a center hole in the center of the workpiece; and when the axial pressing force of the center is adjusted, if the axial pressing force of the center is greater than the elastic force of the liquid plastic, the center moves backwards, and the sharp tooth on the end face of the locking center penetrates into the end face of the workpiece by a certain depth, so that the positioning function of the center and the power transmitting function of the locking center are realized.
Description
Technical field
The present invention relates to a kind of compound toply, particularly a kind of brute force is compound top, 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 thing 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 brute force compound top, 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: a kind of brute force is compound top, it by reconcile screw, sleeve, liquid plastics, lock nut, locked top, the location is top, blanking cover is formed, it is characterized in that: described location is top to be installed in the endoporus of sleeve, locate the top axially movable free degree that in sleeve, has, in the sleeve at top rear portion, location, filling liquid plastics, blanking cover are by the mode of threaded engagement and being installed together of sleeve, and the conciliation screw is installed together by the mode and the blanking cover of threaded engagement;
Described locked top left side is shaped on the sharp pointed tooth that protrudes end face, 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, in advance on the screw thread of the left end cylindrical of sleeve, install lock nut, the turn adjustment screw, make adjustment screw produce certain expansion to liquid plastics after, 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 the elastic force elastic force of liquid plastics, 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.
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, in addition, because liquid plastics can produce bigger compression thrust, so, have the higher characteristics of positioning accuracy.
Description of drawings:
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; 7, blanking cover; A, pointed tooth.
Specific implementation method
To locate 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, filling liquid plastics (3), with blanking cover (7) by the mode of threaded engagement and being installed together of sleeve (2), 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, in advance on the screw thread of the left end cylindrical of sleeve (2), install lock nut (4), turn adjustment screw (1), after making adjustment screw (1) produce certain pre-pressing force, with lock nut (4) and tight locked top (5) to liquid plastics (3).
Claims (1)
1. a brute force is compound top, it is characterized in that: locate top (6) and be installed in the endoporus of sleeve (2), in the sleeve at top (6) rear portion, location, filling liquid plastics (3), adjustment screw (1) are installed on the blanking cover (7), blanking cover is installed in the right-hand member of sleeve (2), and back dead centre (5) is installed in the left end of sleeve (2).
