Abstract
A kind of lathe expanding mandrel device is made up of axle (1), expansion set (2), swelling tapered sleeve (3) and nut (4); It is characterized in that: described expansion set (2) is installed on axle (1) and goes up and evenly process three pairs of grooves, when tightening right part nut (4), by swelling tapered sleeve (3), make expansion set (2) distending, thus realize the effect of holding workpiece.
Description
Technical field
The utility model relates to a kind of lathe expanding mandrel device, belongs to Machining Technology field.
Background technology
In modern mechanical processing, very high to the requirement of exit orifice Vehicle Processing in thin-walled parts in particularly turner production technology, normally used three clamping chuck workpiece carry out cylindrical or endoporus is processed, after taking off workpiece again after thin-walled parts Vehicle Processing is good, just find that distortion is very large like this, will produce and scrap, in order to be qualified product after the thin-walled parts Vehicle Processing that saves production cost, makes, therefore design a kind of lathe expanding mandrel device very necessary.
Utility model content
For solving the problem, the purpose of this utility model is just in order to solve above-mentioned the deficiencies in the prior art, and the purpose of this utility model is to provide a kind of lathe expanding mandrel device.
For solving the problem, the utility model is achieved through the following technical solutions: a kind of lathe expanding mandrel device is made up of axle 1, expansion set 2, swelling tapered sleeve 3 and nut 4; It is characterized in that: described expansion set 2 to be installed in axle 1 and even processing three pairs of grooves, makes expansion set 2 distending, thus realize the effect of holding workpiece when tightening right part nut 4, by swelling tapered sleeve 3.
The beneficial effects of the utility model are: a kind of lathe expanding mandrel device, the advantages such as structure is simple, easy to operate, cost is low, safe and reliable.
Accompanying drawing explanation
Fig. 1 is a kind of lathe expanding mandrel apparatus structure schematic diagram.
Detailed description of the invention
As shown in Figure 1, a kind of lathe expanding mandrel device is made up of axle 1, expansion set 2, swelling tapered sleeve 3 and nut 4; It is characterized in that: described expansion set 2 to be installed in axle 1 and even processing three pairs of grooves, makes expansion set 2 distending, thus realize the effect of holding workpiece when tightening right part nut 4, by swelling tapered sleeve 3.
Below disclose the utility model with better enforcement, so itself and be not used to limit the utility model, allly take equivalent replacement or technical scheme that equivalent transformation obtains, all drop in protection domain of the present utility model.
