Description
[technical field]
The present invention relates to that the pipe fitting to different-diameter carries out the self-centering rolling equipment technical field on the engine lathe, specifically a kind of three wheels self-centering rolling equipment that is used on the engine lathe.
[background technology]
Pipe fitting to different-diameter on the engine lathe carries out self-centering rolling, and rolling goes out the groove of required form.At present, existing rolling device is to adopt single roller rolling pipe fitting on lathe, and there are many weak points in this single roller rolling device: production efficiency and rolling dimensional accuracy are all lower, and the groove quality of rolling is unsatisfactory.Can't overcome when the rolling inner chamber has the pipe fitting of local protrusion shape, be easy to generate and beat and cutter relieving, to such an extent as to influence the disadvantage of slot rolling quality.
[summary of the invention]
Purpose of the present invention is exactly will solve above-mentioned deficiency and a kind of three wheels self-centering rolling equipment that is used on the engine lathe of providing, can overcome single roller when the rolling inner chamber has the pipe fitting of local protrusion shape, be easy to generate and beat and cutter relieving, to such an extent as to influence the disadvantage of slot rolling quality.
Design a kind of three wheels self-centering rolling equipment that is used on the engine lathe for achieving the above object, comprise base, handle, screw mandrel, framework, active rolling wheel device, driven rolling wheel device, framework 8 lower end T shape parts are connected with base 4 grooves and pressing plate 25, initiatively rolling wheel device and driven rolling wheel device are equipped with in the rectangle endoporus place of framework 8, initiatively the rolling wheel device is by short tension spring connecting frame 8 left side frames, on the frame of the framework left side screw mandrel 7 is housed, an end of screw mandrel is provided with handle 6.When handle rotated, screw mandrel was to the motion of framework rectangle endoporus direction, and the pulling force that active rolling wheel device overcomes short tension spring moves forward, until active rolling wheel contact workpiece.
Described active rolling wheel device mainly is made up of rolling wheel support, measurement piece, rolling wheel shaft, short tension spring, moving rolling wheel and supporting plate, rolling wheel support 2 adopts bolt to be connected with supporting plate 3, can in framework 8 endoporus, slide front and back, be equipped with on the rolling wheel support and measure piece 13, rolling wheel shaft 14, be with initiatively rolling wheel 16 on the rolling wheel shaft.
Described driven rolling wheel device mainly is made up of driven rolling wheel, swinging mounting, driven rolling wheel shaft.
Between described framework 8 lower end T shape part one sides and base 4 grooves tent 5 is housed, limited block 26 is equipped with at the bottom tub two ends respectively.
Operation principle is as follows: before the rolling, the handle rotary screw returns to certain position, and framework abuts against on the limited block on the right owing to the effect of long tension spring pulling force, and the rolling wheel support assembly abuts against on the screw mandrel end of framework rectangle endoporus handle one side under the effect of short tension spring pulling force.Have enough space to lay the workpiece of institute rolling between active rolling wheel and two driven rolling wheels this moment.When handle rotated, screw mandrel was to the motion of framework rectangle endoporus direction, and the pulling force that the rolling wheel support assembly overcomes short tension spring moves forward, until active rolling wheel contact workpiece.Behind active rolling wheel contact workpiece, handle is rotated further, and then drives the pulling force that framework overcomes long tension spring, and whole framework is moved to handle orientations, until two driven rolling wheels also contact workpiece.When handle is rotated further, initiatively rolling wheel and two driven rolling wheels then carry out rolling to workpiece synchronously.Because driven rolling wheel is contained on the swinging mounting, swinging mounting can swing up and down according to equilibrium of forces when rolling, makes rolling more steady, helps the raising of rolling quality.The amount of feeding of rolling can be controlled by the dial gauge that is contained on the framework, till being rolled onto needed position.The backward rotation handle, screw mandrel moves in the other direction, the rolling wheel support assembly moves to handle orientations under the effect of short tension spring pulling force, simultaneously framework then under the effect of long tension spring pulling force the opposite direction to handle move, return to initial position until the handle rotary screw, so that there are enough spaces to take out the intact workpiece of rolling between active rolling wheel and the driven rolling wheel.
The present invention compares with adopt single roller rolling pipe fitting on lathe, the production efficiency height, and rolling dimensional accuracy height, the groove quality of rolling is good.Especially this device adopts self-centering three roller rolling forms, can overcome single roller when the rolling inner chamber has the local pipe fitting that protrudes shape, is easy to generate to beat and dodge, to such an extent as to influence the disadvantage of slot rolling quality.Compare with adopting special-purpose rolling installation simultaneously, have small investment, last detective, device is made and advantage easy to maintenance, is worth vast medium-sized and small enterprises to be applied.
