Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Working piece positioning device improving Workpiece Machining Accuracy.
For achieving the above object, the utility model provides following technical scheme: a kind of Working piece positioning device of lathe, comprise the locating piece to Workpiece fixing, it is characterized in that: also comprise the hold down gag compressing described locating piece, described hold down gag comprises guide post, fairlead and the spring be placed in this fairlead, described guide post one end linking springs, the described guide post other end stretches out fairlead and connects locating piece, described fairlead is also provided with the end cap preventing guide post from coming off in fairlead, described fairlead is fixed on backstay, described backstay is movably connected on support bar, described support bar is fixed on the main spindle box of lathe.
By adopting technique scheme, namely workpiece can easily take out from lathe, again can quick position, improves the working (machining) efficiency of workpiece while the machining accuracy improving workpiece.
The utility model is set to further: described support bar is provided with the through hole of strip, and described backstay is through described through hole.
By adopting technique scheme, backstay can move horizontally, and when the length of workpiece is different, only needs to regulate backstay to suitable position just, refer to the machining accuracy of workpiece further.
The utility model is set to further: described backstay by nut check on support bar.
By adopting technique scheme, when diameter of work is in different size, the nut unclamping locking regulates backstay to suitable height, and the elasticity of going back adjustable springs herein improves the machining accuracy of workpiece further.
The utility model is set to further: described guide post is threaded with described locating piece.
By adopting technique scheme, occurring that when locating piece appearance wearing and tearing punctual of location need be changed locating piece and whole positioner need not be made to scrap, having saved cost.
The utility model is set to further: the surface of described locating piece and absorption surface scribbles lubricating oil.
By adopting technique scheme, owing to there being the lubrication of lubricating oil, alleviate the damage of locating piece to workpiece.
Compared with prior art, the beneficial effects of the utility model are: namely workpiece can easily take out from lathe, again can quick position, improve the working (machining) efficiency of workpiece while the machining accuracy improving workpiece.Backstay can move horizontally, and when the length of workpiece is different, only needs to regulate backstay to suitable position just, refer to the machining accuracy of workpiece further.When diameter of work is in different size, the nut unclamping locking regulates backstay to suitable height, and the elasticity of going back adjustable springs herein improves the machining accuracy of workpiece further.Occur that when wearing and tearing appear in locating piece location only need not be changed locating piece on time and whole positioner need not be made to scrap, and has saved cost.Owing to there being the lubrication of lubricating oil, alleviate the damage of locating piece to workpiece.

Detailed description of the invention
Be described further with reference to the embodiment of accompanying drawing to the Working piece positioning device of the utility model lathe.
A Working piece positioning device for lathe, comprise the locating piece 8 of locating workpiece 10, V-type is arranged to by locating piece, and the locating piece 8 of this shape adds anchor point between positioning workpieces 10, can limit the more free degree of workpiece 10, improve machining accuracy.Locating piece 8 scribbles butter with the surface of workpiece 10, alleviates the damage of locating piece 8 pairs of workpiece 10.End cap is threadedly connected to fairlead, and is provided with a through hole.Protruding in the middle part of guide post 7, be stuck in fairlead 6 li by end cap 13, the inner chamber of spring 12 is inserted in one end of guide post 7 projection, the other end of guide post 7 projection through end cap 13 through hole and stretch out fairlead 6 and be threaded with described locating piece 8.Fairlead 6 is fixed on backstay 3, and backstay 3 is threaded, and two nuts 4 are positioned on backstay 3.Support bar 2 is quadrangular shape, has strip through hole 5 above.Backstay 3 is positioned at through hole 5 both sides through 5, two nut 4 distributions of described through hole makes backstay 3 be anchored on support bar 2.Support bar 2 is fixed on the main spindle box 1 of lathe by rivet.
Add man-hour, workpiece 10, by one end of scroll chuck 11 fixation workpiece 10, unclamps the nut 4 be positioned on the upside of through hole 5, regulates backstay 3, makes locating piece 8 move to the other end of the relative scroll chuck 11 of workpiece 10, screws the nut 4 be positioned on the upside of through hole 5.When finding that locating piece 8 is not pressed on workpiece 10, unclamp the nut 4 being positioned at through hole 5 both sides simultaneously, compressed downwards by backstay 3, then the nut 4 be positioned on the downside of through hole 5 is first locked, so just determine the elasticity of spring 12, continue to lock the nut 4 be positioned on the upside of through hole 5, stationary positioned bar 3.The mode of adjusting nut 4 and backstay 3 equally by the way workpiece 10 can be fixed when adding and finding that workpiece 10 radial dimension is excessive man-hour.Meanwhile, also adjusting nut 4 and backstay 3 machining accuracy can be improved by the way when examining workpieces 10 dimensional accuracy finds still undesirable after processing.
By adopting technique scheme, namely workpiece 10 can easily take out from lathe, again can quick position, improves the working (machining) efficiency of workpiece 10 while the machining accuracy improving workpiece 10.Backstay 3 can move horizontally, and when the length of workpiece is different, only needs to regulate backstay 3 to suitable position just, refer to the machining accuracy of workpiece 10 further.When workpiece 10 diameter is different, the nut 4 unclamping locking regulates backstay 3 to suitable height, and the elasticity of going back adjustable springs 12 herein improves the machining accuracy of workpiece 10 further.Occur that when wearing and tearing appear in locating piece 8 location only need not be changed locating piece 8 on time and whole positioner need not be made to scrap, and has saved cost.Owing to there being the lubrication of lubricating oil, alleviate the damage of locating piece to workpiece.
