Abstract
The utility model discloses a fillet press rolling reinforcement device, which comprises a ball bearing [5], a pallet [3], a supporting stand [8], a gland [2] and a spring [7]. The pallet [3] is positioned circumferentially in the cavity [11] of the supporting stand; the press spring [7] is positioned inside the cavity [11] at the lower end of the pallet and fixes the pallet inside the cavity; a through hole [6] that coordinates with the neck section of the working piece is positioned on the pallet; a taper inclined groove that can hold the ball bearing [5] is positioned on the upper end wall of the through hole [6]. By adopting a solid ball bearing that is positioned in a floating pallet, the utility model is able to ensure rolling movement between the ball body and the working piece, thus realizing better press rolling of the working piece, enhancing the speed of press rolling, improving the working efficiency and assuring the processing quality.
Description
Technical field
The utility model relates to the processing unit (plant) that the fillet of roots such as multidiameter, bolt is strengthened.
Background technology
Adopting mechanical system that the fillet of roots such as multidiameter, bolt is strengthened, is a kind of common methods that effectively improves part fatigue behaviour and reliability.Generally speaking, the normal employing with workpiece need be strengthened the similar one or more hard rollers of position shape, or hard spheroid (as steel ball), after applying certain force, by the mutual motion between workpiece and roller or spheroid, thereby finishes reinforcement to the regulation surface.When adopting roller, stock size is bigger, owing to be subjected to the restriction of roller structure, some small size workpiece inconvenience is used; For the workpiece root with on-right angle, roller can interfere with the non-rolling surface of workpiece in use, and the scope of application is subjected to certain restriction.Phenomenons such as when adopting spheroid, generally speaking, the relative motion of spheroid and workpiece is slippage, and speed is low during reinforcement, and peeling appears in surface of the work easily, peel off can't obtain desirable effect.
Summary of the invention
Strengthen processing inconvenience, the bad problem of strengthening effect in order to solve above-mentioned fillet to roots such as multidiameter, bolts, the purpose of this utility model provides a kind of fillet rolling and reinforcing device, not only easy to process, but also can improve strengthening effect, be specially adapted to the finish rolling hardening of the little fillet of workpiece.
The utility model is achieved in that it comprises ball, pallet, supporting seat, gland and stage clip, be provided with the cavity of tray in the supporting seat, pallet circumferentially is fixed in the cavity of supporting seat, stage clip is contained in the cavity of pallet lower end, gland is fixed on the cavity upper end of supporting seat by being threaded, and pallet is fixed in the cavity, pallet is provided with the through hole that cooperates with workpiece neck portion, the upper end wall in hole is provided with the conical skewed slot of placing ball, and ball is placed in the conical skewed slot of pallet.
When using this device, supporting seat is fixed on the platen, workpiece is put into the through hole of pallet again, ball is corresponding to the fillet root of workpiece, the workpiece upper end links to each other with the machine tool rotary end by the connecting rod that floats, along the workpiece axial feed, ball is applied suitable pressure, make the stage clip pressurized and ball is close to the fillet position of workpiece root.When lathe drove the workpiece rotation, ball produced relative motion to workpiece fillet position, strengthened processing thereby finish.Fluctuating of pallet, in conjunction with the resiliency supported of bottom, an axial pinpoint difficult problem in the time of both can eliminating roll extrusion can guarantee the substantially constant of roll extrusion power by adjusting the decrement of stage clip again.
The quantity of ball is the odd number more than three at least, has self-centering effect, makes each ball stressed evenly.
The cavity bottom of supporting seat is provided with and is threaded with supporting seat and is used for regulating the adjusting bolt of stage clip decrement.By regulating the decrement that bolt is regulated stage clip, can obtain the rolling pressure that is fit to easily, thereby obtain desirable strengthening effect.
It is that ball is placed in the unsteady pallet that the utility model adopts the hard spheroid, in the speed of spheroid permission, can guarantee that the motion mode between spheroid and workpiece is rolling, thereby finish the roll extrusion to workpiece preferably.Concrete advantage is as follows:
1, adopts open, relocatable ball pallet, get final product supporting sephere, can in workpiece is packed the formed interblock space in back into, force spheroid in groove, to roll again around the root that the need of workpiece are processed;
2, the design on pallet flute profile inclined-plane can guarantee that the root that is subjected to force direction and workpiece rolling surface of spheroid matches the roll extrusion good positioning effect;
3, the spheroid of three of employings or above odd number has self-centering effect;
4, floating of pallet in conjunction with the resiliency supported of bottom, an axial pinpoint difficult problem can guarantee the constant of roll extrusion power again in the time of can eliminating roll extrusion, therefore both can improve rolling speed, improves work efficiency, can guarantee crudy again;
5, by changing pallet groove surface angle, can be widely used in reinforcement, the root finish rolling hardening of the on-right angle step that particularly suitable common mechanical rolling depression method can't be finished, and the finish rolling hardening of the little fillet of workpiece to roots such as multidiameter, bolts.

The specific embodiment
As illustrated in fig. 1 and 2, supporting seat 8 is the cylindrical shell of a hollow, pallet 3 is embedded in the cavity 11 of supporting seat by supporting seat 8 tops, be fixed with guide finger 1 on cavity 11 walls of supporting seat, make pallet 3 circumferentially be fixed in the cavity 11 of supporting seat 8, to prevent relatively rotating between pallet 3 and the supporting seat 8, gland 2 is fixed on supporting seat 8 upper ends pallet 3 is fixed in the cavity 11 by being threaded, and gland 2 is provided with the through hole that workpiece 9 can pass through.The stage clip 7 of in the cavity of the lower end of pallet 3, packing into, the length of cavity 11 is decided on the length of processing work 9 roots below, and be equipped with by the adjusting bolt 10 that is threaded cavity 11 bottoms, and this bolt 10 is a plug.Have the through hole 6 that processing work 9 roots below can be passed in the middle of the pallet 3, the hole wall upper end of through hole 6 is provided with taper skewed slot 4, rigid balls 5 is bonded on the taper skewed slot 4 by butter, be bonded on the taper skewed slot with butter again after perhaps handling by magnetization, this ball can be with three, also can be with five or other odd number.Add man-hour, workpiece 9 is packed in this device by the upper end, shown in dotted portion among Fig. 2, the root of ball 5 correspondences and workpiece 9, be connected with a connecting rod and workpiece are unsteady, lathe drives the workpiece rotation by connecting rod according to certain speed, simultaneously downwards, only need several seconds, can finish finish rolling hardening workpiece.
