Abstract
The invention provides a strong composite centre with positioning and clamping functions, comprising a regulating screw, a sleeve, a disc spring, a locking nut, a locking centre, a positioning centre, and a plug, the strong composite centre with the positioning and clamping functions is provided with the sleeve, the positioning centre is installed in the inner hole of the sleeve, the positioning centre is provided with a free degree of moving axially in the sleeve, in the sleeve at the rear part of the positioning centre, liquid plastics are filled, the plug and the sleeve are installed together in a mode of screw thread cooperation; at the left end of the sleeve, the locking centre is installed, the positioning centre passes through the middle hole of the locking centre to extend out by a certain length, the locking nut is installed on screw threads of the external circle at the left end of the sleeve, the regulating screw is swirled, making the adjusting screw generate a certain pre-compacting force upon the liquid plastics, and then the locking nut is used to tighten the locking centre.
Description
Technical field
It is compound top to the present invention relates to a kind of brute force, particularly a kind of location, clamps the powerful compound top of function, 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: a kind of location is provided, clamps the powerful compound top of function, this compound top function that had both had centralized positioning, have simultaneously clamping work pieces again, 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 location, clamp the powerful compound top of function, it by reconcile screw, sleeve, disk spring, lock nut, locked top, the location is top, blanking cover is formed, the location, clamp function powerful compound top a sleeve arranged, it is top that one location is 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, the filling liquid plastics, blanking cover is installed together by the mode and the sleeve of threaded engagement; Left end at sleeve, be equipped with one locked top, locate and toply stretch out certain length by locked top interstitial hole, on the screw thread of the left end cylindrical of sleeve, a lock nut is installed, the turn adjustment screw, after making adjustment screw produce certain pre-pressing force, with lock nut and tight locked top to liquid plastics.
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: the present invention is owing to adopt such scheme, the location, clamp the powerful compound top when work of function, the compound top function that had both had centralized positioning, has simultaneously clamping work pieces again, 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, this kind is compound, and top especially to be suitable for cutting output less, fine finishining, and the processing of the workpiece in enormous quantities in the grinding class technology.
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; 7, blanking cover.
Specific implementation method
The location, clamp function powerful compound top a sleeve (2) arranged, one location 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), blanking cover (7) is installed together by the mode and the sleeve (2) of threaded engagement; Left end in sleeve (2), one locked top (5) are installed, locate top (6) interstitial hole by locked top (5) and stretch out certain length, on the screw thread of the left end cylindrical of sleeve (2), a lock nut (4) is installed, 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 (2)
- A location, clamp the powerful compound top of function, it is characterized in that: a location 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), blanking cover (7) is installed together by the mode and the sleeve (2) of threaded engagement;
- According to claims 1 described a kind of location, clamp the powerful compound top of function, it is characterized in that: left end in sleeve (2), one locked top (5) are installed, locate top (6) interstitial hole by locked top (5) and stretch out certain length, on the screw thread of the left end cylindrical of sleeve (2), a lock nut (4) is installed, 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).
