Fig. 2: be Figure 1A-A profile.
Icon wherein:
1-chamfering counterbit, 2-floating centre, 3-backing pin, 4-the second elastomer, 5-cone, 6-spheroid, 7-the first elastomer, 8-concentric column, 9-workpiece, 10-base, 11-workbench, 101-centre bore, 201-cone table, 301-spacing hole, 401-chute.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Shown in Fig. 1-2.Wherein Fig. 1 is concentric facing attachment profile; Fig. 2 is A-A cutaway view in Fig. 1.
This device is the ingenious chamfer tool that utilizes the self-centering principle design of cone, and the cost of processing is reduced greatly, and its principle has replicability.
This device is placed on workbench 11.This device comprises the base 10 for fixture; Chamfering counterbit 1, in order to turner, chamfering counterbit 1 is arranged on machine tool chief axis 12; In chamfering counterbit 1 bottom, be provided with centre bore 101, utilize location that chamfering counterbit 1 centre bore 101 and floating centre 2 realize cutter and device with concentric; On base 10, be provided with concentric column 8, this concentric column 8 is concentric with chamfering counterbit 1; In the upper end of concentric column 8, be provided with inner chamber body (not marking in figure), in inner chamber body, be placed with floating centre 2; Floating centre 2 touches by the first elastomer 7 and inner chamber body bottom connection, realizes elastic movement; The bottom of concentric column 2 is provided with cone table 201, is easy to fixation workpiece.
In order to guarantee that workpiece is in concentric, this device is provided with positioner between floating centre and the bottom of inner chamber body.Wherein positioner comprises centrum 5 and spheroid 6; The upper end of centrum 5 is connected with floating centre 2 by the second elastomer 4, lower end is connected with the bottom of inner chamber body by the first elastomer 7, and spheroid 6 arranges the side of centrum 5, while pressing down centrum 5, spheroid can outwards move, and the inwall of the workpiece 9 of fitting is realized the concentric locating of workpiece 9.Wherein in the first elastomer 7 and second elastomer 4 the present embodiment, all select spring.In order to guarantee that cone 5 always has descending trend, realize the self centering object of spheroid 6, require the second elastomeric elastic force to be greater than the first elastomeric elastic force.Spheroid is more than 3, and still 3 spheroids can reasonablely be located, therefore choose 3 spheroids in the present embodiment, wherein spheroid is selected steel ball.
In the present embodiment, the top of the concentric column 8 of this device is also provided with in spacing hole 301, one backing pins 3 the are placed in floating centre chute 401 of side through spacing hole 301, has guaranteed floating centre difficult drop-off.
The course of work is as follows:
(1) first this device is placed on the workbench 11 of drilling machine, and centering machine tool chief axis 12 and the concentric requirement of floating centre 2, then base 10 is fixed on workbench 11.
(2) workpiece 9 is inserted in concentric column 8, the end opening of workpiece 9 contacts (being cone table 201) with the lower end tapering of concentric column 8, chamfering counterbit 1 packs the interior incorporating mill bed of machine tool chief axis 12 main shaft into and moves down and make the lower end centre bore 101 of counterbit 1 contact (now counterbit does not also contact with workpiece mouth) with floating centre 2, it is that floating centre 2 moves down that machine tool chief axis 12 continues to move down, now floating centre 2 moves down and compresses the second elastomer 4 in concentric column 8, and compressing cone 5, the second elastomer 4 move down and utilize the conical surface to push three steel balls 6 open, thereby it is concentric with machine tool chief axis 12 to realize workpiece 9 endoporus, machine tool chief axis 12 continues to move down and rotate the orifice chamfer that utilizes the decrement of the second elastomer 4 to complete workpiece 9.
(3) workpiece 9 chamferings reach after requirement, on machine tool chief axis 12, move to chamfering counterbit 1 and leave floating centre 2, now floating centre 2 rises to free state under the effect of ground two elastomers 4, and cone 5 rises under the effect of the first elastomer 7, now three steel balls 6 are pressure-less state, workpiece 9 is just easy to take out like this, and workpiece 9 tunes pack into can process other end chamfering.
This device applicability is strong, on common drilling machine, can process, simple to operate.The axiality of chamfering and endoporus can guarantee, in φ 0.15, to have reached the instructions for use of product.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
