The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
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.
