Abstract
The utility model discloses a kind of lathe overcurrent protection structure; include mandrel; mandrel is set with clutch sub-set, clutch dog core; be assemblied in the expanding mouth in clutch sub-set front end on rear side of clutch dog core; also be provided with multiple cavity in clutch sub-set, in each cavity, rear end has been screwed into screw, and screw is connected with spring; spring spring end is connected with steel ball, and steel ball part is exposed from cavity front end accent and supported on rear side of clutch dog core.The utility model can play the effect of protection lathe miscellaneous part.
Description
Technical field
The utility model relates to machine tool field, specifically a kind of lathe overcurrent protection structure.
Background technology
lathe is the important production equipment for processing equipment parts in modern industry, in national modernization construction, play important effect.Clutch dog core is the accessory that lathe is conventional, and in use, the phenomenon of excess load often appears to prior art lathe in clutch dog core, easily causes miscellaneous part on lathe to damage.
utility model contentthe purpose of this utility model is to provide a kind of lathe overcurrent protection structure, easily causes to solve prior art lathe clutch dog core excess load the problem that on lathe, miscellaneous part damages.
In order to achieve the above object, the technical scheme that the utility model adopts is:
Lathe overcurrent protection structure, it is characterized in that: include mandrel, mandrel is set with clutch sub-set, clutch sub-set front end is set to expanding mouth, mandrel is also set with clutch dog core, and be assemblied in the expanding mouth in clutch sub-set front end on rear side of clutch dog core, multiple cavity is also provided with in described clutch sub-set, each cavity central axis and mandrel centerline axis parallel, multiple cavity uniform ring is around mandrel, and each cavity rear end accent is arranged on clutch sub-set rear end, each cavity front end accent is communicated with in the expanding mouth of clutch sub-set, in each cavity, rear end has been screwed into screw, described screw is connected with spring, spring spring end stretches to the expanding mouth of clutch sub-set, and spring spring end is connected to steel ball, described steel ball part is exposed from cavity front end accent and is supported on rear side of clutch dog core.
Described lathe overcurrent protection structure, is characterized in that: be provided with annular groove on rear side of described clutch dog core, and described steel ball part is exposed from cavity front end accent and to be supported on rear side of clutch dog core annular groove.
In the utility model, by the elastic force of screw adjustment spring, make the frictional force producing needs between steel ball and clutch dog core, when running into excess load, clutch dog core and clutch sub-set can relative slidings, thus play the effect protecting lathe miscellaneous part.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
