Abstract

A centre mechanism of a cutting machine tool is characterized in that liquid plastic and a belleville spring are disposed in the inner cavity of a bush, the belleville spring is positioned by a positioning shaft in a sealed manner, a sharp tooth is disposed at the front end of the liquid plastic, a locking nut and a locking centre mechanism are respectively disposed on t he outer side of the sharp tooth, and a positioning centre is mounted at the top end of the locking centre mechanism and the sharp tooth. The centre mechanism is simple in structure, accurate in positioning, fast in transmission, good in universality and high in automation level.

Description

A kind of stock-removing machine tip mechanism
Technical field
The present invention relates to a kind of tip mechanism, particularly a kind of stock-removing machine tip mechanism, belong to stock-removing machine attachment technique field.
Background technology
Top is critical function parts in Metal Cutting Machine Tool, and it is generally arranged in stock-removing machine barrel of tail stock in lathe, or is arranged in the spindle hole of barrel of tail stock and stock-removing machine simultaneously; No matter it takes which kind of mounting means on stock-removing machine, and its main function has been exactly the effect of centralized positioning, with chuck or the first-class clamp workpiece of heart carrier for bolt in the process of processing, to transmit the power in cutting.Because existing top has the function of location, so clamping must be carried out respectively with location at work, and when working shaft-like part in enormous quantities, clamping work pieces is a pretty troublesome thing of also losing time, and reduces the efficiency that work is produced to a certain extent.
Summary of the invention
The object of the invention is to: provide that a kind of structure is simple, accurate positioning, transmission is rapid, universal performance good, automaticity is high a kind of stock-removing machine tip mechanism, overcome the above-mentioned defect existing for existing tip mechanism.
The technical solution adopted for the present invention to solve the technical problems is: a kind of stock-removing machine tip mechanism, it is made up of locating shaft, sleeve, disk spring, liquid plastics, lock nut, locked tip mechanism, locating centre, pointed tooth, described tip mechanism is provided with liquid plastics and disk spring in the inner chamber of sleeve, and disk spring seals location by locating shaft; The front end of liquid plastics is provided with a pointed tooth, is respectively arranged with lock nut and locked tip mechanism in the outside of pointed tooth, on the top of locked tip mechanism and pointed tooth, one locating centre is installed.
Operation principle of the present invention is: by top for above-mentioned integrally mounted lathe, in the spindle hole being fixed on lathe by the cylindrical of tailstock sleeve or barrel of tail stock, locating centre positions with the central term pointed orifice of workpiece, when regulating the axial pressing force of locating centre further, the axial pressing force of locating centre is greater than disk-shaped spring elasticity, so, locating centre just moves backward, until the end face certain depth that the sharp pointed tooth of locked top end face thrusts workpiece just starts to stop, now, the pointed tooth that locked top end face is sharp thrusts the end face of workpiece, workpiece is made toply to become to be integrated with locked, so, realize by top location, the function of locked top transmission power.
Beneficial effect of the present invention: when the present invention works, locating centre had both had the function of centralized positioning, there is clamping work pieces simultaneously, transmit the function of cutting power, overcome that existing top single positioning function brings owing to only having: positioning and clamping must carry out respectively, and the scarce limit of the reduction labor productivity caused thus, so the present invention has that structure is simple, accurate positioning, transmission is rapid, universal performance good, automaticity is high advantage.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, structure of the present invention is described further.
Fig. 1 is structure principle chart of the present invention.
Shown in figure: 1, locating shaft; 2, sleeve; 3, disk spring; 4, liquid plastics; 5, lock nut; 6, locked tip mechanism; 7, locating centre; 8, pointed tooth.
Detailed description of the invention
Stock-removing machine tip mechanism has a sleeve (2), is provided with liquid plastics (4) and disk spring (3) in the inner chamber of sleeve (2), and disk spring (3) seals location by locating shaft (1); The front end of liquid plastics (4) is provided with a pointed tooth (8), is respectively arranged with lock nut (5) and locked tip mechanism (6) in the outside of pointed tooth (8), at locked tip mechanism (6) and the top of pointed tooth (8), a locating centre (7) is installed.
