It is entirely therefore to be had the following disadvantages by manually completing this procedure, use is very inconvenient, low production efficiency, waste
Time.
In recent years, flourishing with China's machinery manufacturing industry, mantle fiber operation is also more widely used in all kinds of machines
In tool processing industry.Common threading device has manual threading device and electronic two class of Special threading machine.Manual threading device work
It is low to make efficiency, mantle fiber low precision；And though electronic Special threading machine can guarantee the work efficiency and precision of mantle fiber, higher operating costs,
It is not appropriate for the small lot mantle fiber operation of medium-sized and small enterprises.And currently, the well known threading device structure for carrying out mantle fiber using lathe
More complex, making is cumbersome, and versatility is poor.
Invention content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of center lathe threading tools, are not moving
In the case of lathe tailstock, realization workpiece mantle fiber that can be easily and fast.
The utility model is in order to solve the above technical problems, used technical solution is：A kind of center lathe mantle fiber work
Dress, including die sleeve, described die sleeve one end are equipped with first step hole, and the other end is equipped with second step hole, the first step
For installing screw die in hole and second step hole, the size in the first step hole and second step hole differs, the screw die
Set is internally provided with the through-hole that can wear guide rod, is fixedly connected with taper shank on the outside of the guide rod.
Preferably, the first step hole and second step hole side wall are equipped with the threaded hole that can install screw.
Preferably, the tapped blind hole for installing auxiliary rod is further opened on the die sleeve side wall.
Preferably, the cylindrical structure of the die sleeve generally inner hollow, the first step hole and second step
Hole is the mutually different cylindrical empty cavity configuration of radius.
Preferably, it is additionally provided with auxiliary round block in the first step hole and second step hole.
The beneficial effects of the utility model：The threading clamp of the utility model is simple in structure, easy to operate, can utilize common
Lathe carries out automatic mantle fiber, not only avoids using electronic Special threading machine and making cost higher, but also overcome manual mantle fiber dress
The problem of setting low working efficiency, mantle fiber low precision, significantly reduces the labor intensity of operating personnel, laborsaving, mantle fiber efficiency when section
It is higher with precision.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of center lathe threading tool；
Fig. 2 is the internal structure schematic diagram of Fig. 1；
Fig. 3 is the structural schematic diagram for assisting round block；
It is die sleeve 1, first step hole 2, second step hole 3, screw die 4, guide rod 5, through-hole 6, taper shank 7, screw 8, auxiliary in figure
Help bar 9, tapped blind hole 10, auxiliary round block 11.
Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figures 1 to 3, a kind of center lathe threading tool, including die sleeve 1,1 one end of the die sleeve are equipped with the
One stepped hole 2, the other end are equipped with second step hole 3, are used to install screw die 4 in the first step hole 2 and second step hole 3,
The size in the first step hole 2 and second step hole 3 differs, and the die sleeve 1, which is internally provided with, can wear the logical of guide rod 5
Hole 6,5 outside of the guide rod are fixedly connected with taper shank 7.
Preferably, the first step hole 2 and 3 side wall of second step hole are equipped with the threaded hole that can install screw 8.This
Screw die 4 can be fixed in first step hole 2 or second step hole 3 by screw 8 after sample design.
Preferably, the tapped blind hole 10 for installing auxiliary rod 9 is further opened on 1 side wall of the die sleeve.In practical system
During making, when encounter processing it is relatively low as part hardness such as aluminium class, iron class, 45 steel classes when, there is no need to load onto auxiliary rod 9, but
When processing part with high hardness as titanium alloy, processing request is not achieved by die sleeve 1, screw die 4 and lathe positive and negative rotation processing,
Auxiliary rod 9 need to set are embodied as injecting taper shank 7 in the tailstock of center lathe, auxiliary rod 9 are placed on lathe saddle
Folder cutter groove on.
Preferably, the cylindrical structure of the generally inner hollow of the die sleeve 1, the first step hole 2 and second
Rank hole 3 is the mutually different cylindrical empty cavity configuration of radius.
Preferably, it is additionally provided with auxiliary round block 11 in the first step hole 2 and second step hole 3.In practical manufacturing process
In, when processed threading die outer diameter is less than 3 size of first step hole 2 or second step hole, it is firm to have a clamping, just
It cannot be processed, in addition after auxiliary round block 11, it is firm that clamping is stablized, and can meet processing request, and auxiliary round block 11 can be done
At different sizes, meet different screw die clamping requirements.
The present embodiment operation principle is as follows：
4 clamping of screw die can be selected in first step hole 2 or the second according to parts to be processed thread size in the present embodiment
In stepped hole 3, avoid fixture in the prior art can only one screw die of clamping defect, while when stepped hole is more than plate
4 outer bowlder of tooth, screw die 4 will have the illusive defect of clamping, thus Design assistant round block 11, and auxiliary round block 11 can basis
4 size of different screw die does different sizes, and to meet different thread size processing requests, die sleeve 1 is central axial to be offered
Through-hole 6 allows guide rod 5 to slide back and forth to realize back-and-forth motion along through-hole 6；
When carrying out mantle fiber operation, first lathe tailstock is fixed, then 7 rear portion of taper shank is fixedly arranged on lathe tailstock, according to set
Silk needs, and suitable screw die 4 is packed into first step hole 2 or second step hole 3, screw 8 is tightened, screw die 4 is fastened, wanting
The parts fixation of processing is on lathe chuck, mobile Lathe Spindle Box, will mantle fiber one end alignment screw die 4 and after being engaged, it is quiet
Only Lathe Spindle Box rotates in the forward direction processing part using the rotation of lathe spindle, starts mantle fiber, and screw die 4 drives die sleeve 1 leading
To sliding before on bar 5, it is automatically performed axial feed, when mantle fiber is to required length, reversely rotates part, screw die 4 exits processing
Part completes mantle fiber operation.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model
System, the features in the embodiments and the embodiments of the present application in the absence of conflict, mutually can be combined arbitrarily.This practicality is new
Technical characteristic in the technical solution that the protection domain of type should be recorded with claim, including the technical solution of claim record
Equivalents are protection domain.Equivalent replacement i.e. within this range is improved, also the scope of protection of the utility model it
It is interior.
