Abstract
The utility model relates to machine work equipment, particularly a multifunctional movable centre in a lathe tailstock. The original integral movable center is separated to a center body and a center head by the center, and the left end of the center body is provided with a drogue which can be provided with a locating piece, a grinding fixture or a tool head; when the utility model is used as a center, the center head is installed in the drogue; for example, the grinding fixture head or the tool head is used to replace the center head to be installed into the drogue to have the functions of grinding and milling; in addition, the center can be supported by the tool bar and shaft parts through the drogue; in conclusion, the center has the advantages of multiple function and convenient application, and saves the supplementary time of processing and the consumption of various materials.
Description
It is top that the utility model relates to a kind of multifunctional movable that is used for machining apparatus, particularly tail stock.
The rolling center that uses on traditional lathe has only a fixing centre head, can not adapt to the changeable occasion of processing situation.As process the little part of axle head diameter, and need could continue feed, otherwise lathe tool can be run into centre head to the cutter head sharpening, certainly will influence cutter head intensity and lathe tool service life like this, increase emery wheel consumption and processing non-cutting time.And for example process the bigger axle sleeve class part in aperture, must join car silently, could process with conventional rolling center clamping.
The purpose of this utility model is to overcome the defective that can not adapt to multiple machining status that existing rolling center exists, provide a kind of can be according to the needs of workpiece, the multifunctional movable of changing size, variform centre head is top.
Another purpose of the present utility model provides a kind of positioning function that not only has rolling center, and it is top to have a multifunctional movable of grinding and milling function and supporting axis class, knife bar base part function.
Task of the present utility model realizes in the following manner: be about to the integral type rolling center and be separated into top body and centre head two parts, the left end of top body is provided with the tapered sleeve that keeper, grinding tool or cutterhead can be installed, and centre head is contained in the tapered sleeve.
As replacing centre head to be contained in the tapered sleeve by bolt with grinding tool head or cutterhead, and set up an auxiliary small machine below top body, multifunctional movable is top to have grinding or a milling function just can make.
Multifunctional movable is top by tapered sleeve, also can realize the support of knife bar class, axle base part.
In the utility model, keeper comprises the minor diameter centre head, and major diameter centre head, head are the centre head of taper hole and the centre head that other designs as required.
Centre head of the present utility model is compared with existing rolling center, and function is many, and is easy to use.Save the non-cutting time of processing and the consumption of various materials, improved clamping rigidity and precision, improved productivity ratio.When the little part of need processing axle head diameter, need only change the little centre head of diameter, use 90 ° of general offset tools to process; When the bigger axle sleeve class part in need processing aperture, need only change the major diameter centre head and can process, saved processing time and materials silently, and the clamping precision height, good rigidly; When part axle head that must processing is the cusp configuration at any angle that protrudes or other shape, all can disposes suitable centre head voluntarily and produce in enormous quantities by the user; When axle head does not allow centre bore, can utilize facing surplus car to go out about a long 2mm, the convex that diameter cooperates with the tapered sleeve hole holds out against and can process with the aperture, can save the cutting length consumption; If utilize lathe to carry out boring, Milling Process, the end of knife bar near tailstock cooperated with tapered sleeve, can finish high-speed cutting, and good rigidly, the precision height; When replacing centre head to be contained in the tapered sleeve grinding tool head or cutterhead, the top work that just can finish grinding or milling of multifunctional movable.In addition, this rolling center needing on the various lathes also to can be used for frequent disengagement, joint, high speed to rotate, and keeps high accuracy and the axle class of enough rigidity, the support of knife bar class.
Concrete structure of the present utility model is provided by drawings and Examples.
Fig. 1 is the structural representation of the utility model during as rolling center;
Fig. 2 is used for the centre head schematic diagram that the end is the workpiece of taper;
Fig. 3 is the structural representation of major diameter centre head;
Structural representation when Fig. 4 loads onto the grinding tool head for the utility model.
Below in conjunction with drawings and Examples the utility model is described in more detail.
Embodiment 1:
With reference to Fig. 1, the left end of the top body 1 that multifunctional movable is top is equipped with tapered sleeve 2, and dress minor diameter centre heads 3 in the tapered sleeve 2 when must changing when top, put in the top body afterbody hole centre head 3 ejected with iron staff and get final product.
Embodiment 2:
With reference to Fig. 4, the left end of top body 1 is equipped with tapered sleeve 2, and grinding tool head 4 is housed in the tapered sleeve 2, and tighten up by bolt 5, below top body 1, adorn an auxiliary small machine, drive the belt pulley on bistrique 4 and make bistrique 4 rotation at a high speed by it, like this, just grinding can have been finished.
Claims (3)
1. a multifunctional movable that is used for machining apparatus, particularly tail stock is top, it is characterized in that: the left end of top body 1 is provided with the tapered sleeve 2 that keeper, grinding tool or cutterhead can be installed, and location centre head 3 is housed in the tapered sleeve 2.
2, multifunctional movable according to claim 1 is top, it is characterized in that: grinding tool head 4 is contained in the taper hole 2 by bolt 5.
3, multifunctional movable according to claim 1 is top, it is characterized in that: keeper is meant that minor diameter centre head, major diameter centre head and head are the centre head of taper hole.
