Abstract
The utility model discloses the floating type follow-rest of a kind of three roller, belong to and relate to field of machining, draw together support, flexible media is provided with in the cavity of described support, the opposite side of described flexible media is provided with back-up ring, the opposite side of described back-up ring is provided with upper push-rod and lower push-rod and middle push rod, and described middle push rod directly contacts with described flexible media; The other end of described upper push-rod is connected with upper connecting rod and upper roller; The other end of described middle push rod is connected with middle roller; The other end of described lower push-rod is connected with lower connecting rod and bottom roller; In process, the radial cutting that workpiece is subject to moves pressure flexible media thus lays down radial cutting force after trying hard to recommend middle bearing claw avoids flexural deformation, drive upper and lower two bearing claws automatically to adjust and the contact position of workpiece and tightness simultaneously, three, upper, middle and lower bearing claw by upper roller, middle roller, bottom roller and surface of the work Structure deformation, achieves the object not only increasing workpiece rigidity but also avoid defective work piece surface.
Description
Technical field
The utility model relates to field of machining, particularly relates to the floating type follow-rest of a kind of three roller.
Background technology
In field of machining, time processing slim axle (draw ratio L/D>15), produce flexural deformation to prevent workpiece to be subject to the effect of radial cutting force, common central frame or follow-rest as aiding support, to increase workpiece rigidity.Follow-rest is fixed on saddle side, with knife rest lengthwise movement.The bearing claw of follow-rest, immediately following playing aiding support effect after lathe tool.Therefore, when processing slim optical axis, needing to use follow-rest, for reducing and stable resistance to cutting, protection cutter, reducing the impact of vibration on cutter.But existing common follow-rest generally only has upper and lower two bearing claws, simultaneously due to the structure of two bearing claws, in process, the rigidity of two bearing claws is not enough, and fragile surface of the work.
Summary of the invention
The purpose of this utility model is just to provide a kind of and has good rigidity and the floating type follow-rest of three rollers on not easily defective work piece surface, to solve the problem.
To achieve these goals, the technical solution adopted in the utility model is such: the floating type follow-rest of a kind of three roller, comprise support, described Bracket setting has cavity, flexible media is provided with in described cavity, the side of described flexible media is provided with back shroud, and described flexible media is closed in described cavity by described back shroud; The opposite side of described flexible media is provided with back-up ring, the opposite side of described back-up ring is provided with upper push-rod and lower push-rod, also be provided with middle push rod, described middle push rod is between described upper push-rod and described lower push-rod, and described middle push rod directly contacts with described flexible media; The other end of described upper push-rod is connected with upper connecting rod, is connected with upper roller at the end of described upper push-rod simultaneously; The other end of described middle push rod is connected with middle roller; The other end of described lower push-rod is connected with lower connecting rod, is connected with bottom roller at the end of described lower push-rod simultaneously.
Upper push-rod and upper connecting rod link together and to form upper bearing claw with upper roller; Bearing claw during the middle push rod directly contacted with flexible media and middle roller are formed; Lower push-rod and lower connecting rod link together and form lower support pawl with bottom roller; Three, upper, middle and lower bearing claw holding workpieces.
In process, the radial cutting that workpiece is subject to moves pressure flexible media thus lays down radial cutting force after trying hard to recommend middle bearing claw avoids flexural deformation, drive upper and lower two bearing claws automatically to adjust and the contact position of workpiece and tightness simultaneously, three, upper, middle and lower bearing claw by upper roller, middle roller, bottom roller and surface of the work Structure deformation, achieves the object not only increasing workpiece rigidity but also avoid defective work piece surface.
As preferred technical scheme: described upper push-rod is fixedly connected with described upper roller by bearing pin.
As preferred technical scheme: described lower push-rod is fixedly connected with described bottom roller by bearing pin.
Compared with prior art, the utility model has the advantage of: in process, the radial cutting that workpiece is subject to moves pressure flexible media thus lays down radial cutting force after trying hard to recommend middle bearing claw avoids flexural deformation, drive upper and lower two bearing claws automatically to adjust and the contact position of workpiece and tightness simultaneously, three, upper, middle and lower bearing claw by upper roller, middle roller, bottom roller and surface of the work Structure deformation, achieves the object not only increasing workpiece rigidity but also avoid defective work piece surface.

In figure: 1, base; 2, screw is adjusted; 3, back shroud; 4, filler plug; 5, sealing ring; 6, flexible media; 7, back-up ring; 8, middle push rod; 9, upper push-rod; 10, upper connecting rod; 11, upper roller; 12, bearing pin; 13, workpiece; 14, middle roller; 15, bottom roller; 16, lower push-rod; 17, lower connecting rod; 18, support.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1:
See Fig. 1, the floating type follow-rest of a kind of three roller, comprise support 18, comprising support 18 is clamped on base 1 by adjustment screw 2, support 18 is provided with cavity, be provided with flexible media 6 in described cavity, the side of flexible media 6 is provided with back shroud 3, and filler plug 4 and sealing ring 5 cooperation are tightened back shroud 3 and be enclosed in by flexible media 6 in the cavity of support 18; The opposite side of flexible media 6 is provided with back-up ring 7, and the opposite side of back-up ring 7 is provided with upper push-rod 9 and lower push-rod 16, is also provided with middle push rod 8, and middle push rod 8 is between upper push-rod 9 and described lower push-rod 16, and middle push rod 8 directly contacts with flexible media 6; The other end of upper push-rod 9 is connected with upper connecting rod 10, is connected with upper roller 11 at the end of upper push-rod 9 by bearing pin 12 simultaneously; The other end of middle push rod 8 is connected with middle roller 14; The other end of lower push-rod 16 is connected with lower connecting rod 17, is connected with bottom roller 15 at the end of lower push-rod 16 by bearing pin 12 simultaneously;
In use procedure, three, upper, middle and lower bearing claw holding workpieces 13.The radial cutting that in process, workpiece 13 is subject to moves pressure flexible media 6 thus lays down radial cutting force after trying hard to recommend middle bearing claw avoids flexural deformation, drive upper and lower two bearing claws automatically to adjust and the contact position of workpiece 13 and tightness simultaneously, three, upper, middle and lower bearing claw is contacted with workpiece 13 surface scrolls by upper roller 11, middle roller 14, bottom roller 15, achieves the object not only increasing workpiece 13 rigidity but also avoid defective work piece 13 surface.
