Background technique
Numerically controlled lathe is to use relatively broad one of numerically-controlled machine tool at present.Numerically-controlled machine tool is added according to what is woven in advance
Engineering sequence, automatically processes part to be processed, our fortune the machining process route of part, technological parameter, cutter
Dynamic rail mark, displacement, cutting parameter and miscellaneous function are written as according to instruction code as defined in numerically-controlled machine tool and program format
Processing program list, then the content record in this program list is then input to the numerical control device of numerically-controlled machine tool on control medium
In, to command machine tooling part.It is mainly used for the inside and outside cylindrical surface of axial workpiece or disk-like accessory, any cone angle it is interior
The machinings such as positive camber and cylinder, tapered tread in outer conical surface, complicated revolution, and can be carried out grooving, drilling, reaming, hinge
Hole and bore hole etc..
Workpiece clamping mode mainly has the mode of chuck, collet on lathe at present.Collet clamping mode can
So that the deformation of Workpiece clamping position circumferentially is smaller, and it is also more economical compared to chuck, it is also easier in production, so
Using also very universal.
But in the way of collet clamping, in clamping process, because of the difference of batch workpiece outer dimension, clamp
Afterwards, the displacement of collet in the axial direction is also different, and in general, cone angle is smaller, and displacement difference in the axial direction is bigger.Generally exist
When having axially position requirement, needs to increase in the aperture of collet corresponding sink by face and realize, but if positioning requirements are very high
In the case where, it may require that the consistency of guarantee blank shape size to realize.Such as: increase outer circle or four directions, six side surfaces plus
Work process, to reduce the deviation between batch workpiece, this will lead to process equipment, personnel, working hour increase, this be just the producer with
Puzzlement is carried out.
Summary of the invention
The purpose of this utility model is to provide a kind of axial high-precision positioners of lathe workpiece, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of lathe workpiece axial high-precision positioner, including support sleeve, mandril and lock sleeve, the support sleeve peace
Mounted in the rear end face of the rotary cylinder of lathe, support sleeve is connected with the pull rod of lathe, and mandril is fixed on the interior of pull rod and support sleeve
In hole and mandril upper end installs axle sleeve additional, and the end of mandril is in contact with workpiece and is fixed using lock sleeve.
As a further solution of the present invention: support sleeve is turned by the rear end face phase of flange and the rotary cylinder of lathe
It connects.
As a further solution of the present invention: the quantity of axle sleeve is two or more.
As a further solution of the present invention: mandril is locked at the inner hole of pull rod and support sleeve by holding screw
In.
As a further solution of the present invention: being cooperated between axle sleeve and pull rod using small―gap suture.
As a further solution of the present invention: support sleeve, mandril and lock sleeve are all made of stainless steel material production.
As a further solution of the present invention: the nominal diameter of holding screw is 10-25mm.
Compared with prior art, the utility model has the beneficial effects that this product design is rationally, structurally and operationally simply,
Only mandril and the position of holding screw, which need to be adjusted, can ensure axially position precision, and the consistency between part volume is good；This
Product cost reduces, without increasing preceding working procedure, workpiece caused by can effectively preventing because of workpiece surface characteristic size deviation
Axial displacement is different, primary to put into, and can exempt the cost for increasing process, suitable for the workpiece of different position lengths, and adjusts
It is convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the axial high-precision positioner of lathe workpiece.
Fig. 2 is the cross-sectional view in the direction A-A in the axial high-precision positioner of lathe workpiece.
Wherein: 1- support sleeve, 2- mandril, 3- flange, 4- axle sleeve, 5- workpiece, 6- lock sleeve, 7- holding screw, 8- lathe.
Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment.
Embodiment 1
A kind of lathe workpiece axial high-precision positioner, including support sleeve 1, mandril 2 and lock sleeve 6, the support
Set 1 is mutually transferred by flange 3 and the rear end face of the rotary cylinder of lathe 8, and support sleeve 1 is connected with the pull rod of lathe 8, and mandril 2 is logical
Cross holding screw 7 be locked in the inner hole of pull rod and support sleeve 1 and 2 upper end of mandril install additional axle sleeve 4, the nominal of holding screw 7
Diameter is 10-25mm, and the end of mandril 2 is in contact with workpiece 5 and is fixed using lock sleeve 6.
Embodiment 2
A kind of lathe workpiece axial high-precision positioner, including support sleeve 1, mandril 2 and lock sleeve 6, the support
Set 1 is mutually transferred with the rear end face of the rotary cylinder of lathe 8, and support sleeve 1 is connected with the pull rod of lathe 8, mandril 2 be locked at pull rod with
