Description
Technical field
The utility model relates to the frock technical field, especially relates to a kind of workpiece centering device.
Background technology
On lathe, the method for working shaft-like workpiece is: in an end of workpiece machining center hole in advance, and after lathe on workpiece, top this centre bore that holds out against of tail stock, the lathe chuck clamping work pieces other end, processed after adjusting chuck centering workpiece.Its defect is: the centre of gyration that the centre bore of processing may not be in workpiece in advance, especially more for step or the workpiece that forges, expect also to be difficult to guarantee fully that central hole location is accurate even rule to borrow by platform.So, if centre bore is not just, can't the centering workpiece only according to adjusting chuck, thus can only be at workpiece other end machining center hole again.
Summary of the invention
The purpose of this utility model is to provide a kind of workpiece centering device, and it has the advantages that can facilitate, accurately workpiece be carried out centering.
The technical scheme that the utility model adopts is: workpiece centering device, it is arranged on tail stock, for workpiece is carried out to centering, described workpiece centering device comprises body, the right-hand member of this body is provided with the right jack inserted for workpiece, and the puller bolt that the circumference side that is provided with uniformly 4 and this workpiece on the sidewall of this right jack matches, simultaneously, the left end of this body is provided with left jack, in this left jack, be inserted with and taper shank that this tail stock matches, this taper shank middle part is provided with first step, the locking nut that the oral area of this left jack is bolted with and the left surface of this first step matches.
Described left jack inside is provided with and holds out against step, and this holds out against between the right flank of step and this first step and is provided with plane bearing.
The right side that is positioned at this first step on described taper shank is provided with second step, between the right side of this second step and this left jack, is provided with bearing.
The advantage that compared to the prior art the utility model had is: can facilitate, accurately workpiece be carried out to centering.Workpiece centering device of the present utility model is in use without machining center hole in advance on workpiece, and only needing can be by the axial line adjustment of this workpiece in place by adjusting 4 puller bolts.That is, by adjusting 4 puller bolts, this workpiece is carried out to centering.Also can say, be similar at the two ends of workpiece and all by the mode of chuck, carried out centering, for convenience, accurately.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is that the workpiece centering device of embodiment of the present utility model is looked cutaway view the master of the state of use;
Fig. 2 is that the master of decomposing state of the workpiece centering device of embodiment of the present utility model looks cutaway view.
In figure: 10, body, 11, right jack, 12, left jack, 121, hold out against step; 20, puller bolt; 30, taper shank, 31, first step, 32, second step; 40, locking nut; 50, plane bearing; 60, bearing.
The specific embodiment
Embodiment, see shown in Fig. 1 and Fig. 2: workpiece centering device is arranged on tail stock 100, for workpiece 200 is carried out to centering.Specifically, this workpiece centering device comprises body 10, and the right-hand member of this body 10 is provided with the right jack 11 inserted for workpiece 200, and is provided with uniformly the puller bolt 20 that the circumference side of 4 and this workpiece 200 matches on the sidewall of this right jack 11.That is, the inner of this puller bolt 20 can withstand on the circumference side of this workpiece 200.Obviously, what is called is uniformly distributed, and refers to the sidewall even circumferential distribution of these 4 puller bolts 20 along this right jack 11.Simultaneously, the left end of this body 10 is provided with left jack 12, in this left jack 12, is inserted with and taper shank 30 that this tail stock 100 matches.That is, this taper shank 30 is connected with this tail stock 100.These taper shank 30 middle parts are provided with first step 31, the locking nut 40 that the oral area of this left jack 12 is bolted with and the left surface of this first step 31 matches.That is, this locking nut 40 is limited in this taper shank 30 in this left jack 12, avoids this taper shank 30 to deviate from.In use, the left end of workpiece 200 is inserted in this right jack 11, the inner of these 4 puller bolts 20 is held out against on the circumference side of this workpiece 200, then, this taper shank 30 is connected with this tail stock 100, adjusts this 4 puller bolts 20, can be to the left end centering of this workpiece 200, turn the adjusting of chuck in conjunction with four of workpiece 200 right-hand members, can facilitate, realize accurately the centering of this workpiece 200.
Optimize: these left jack 12 inside are provided with and hold out against step 121, and this holds out against between the right flank of step 121 and this first step 31 and is provided with plane bearing 50.The right side that is positioned at this first step 31 on this taper shank 30 is provided with second step 32, between the right side of this second step 32 and this left jack 12, is provided with bearing 60.Obviously, the setting of this bearing 60 and this plane bearing 50 can be rotated this taper shank 30 smoothly.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
