The assistant tool can automatically adjust the position of the lathe tool with the change of coaxiality or wall thickness of workpieces, thus avoiding the phenomena such as penetration or uneven wall thickness and improving the yield of the workpieces.
Description
Technical field
The utility model relates to a kind of turning accessory that is used for thin-walled parts.
Background technology
At present, in machining, often meet the processing of thin-walled major diameter part, be common in tube kind part especially, when this type of thin-walled parts of processing, because diameter of part is bigger, wall thickness, so part poor rigidity, and because the mode of base, the circularity of blank is poor, inside and outside axiality is poor, adopts conventional processing accessory, because lathe tool can not be adjusted the position with the variation of workpiece axiality or wall thickness, cause that the part that processes is very easy phenomenons such as car is worn, roughness is seriously defective, wall unevenness is even to occur, cause part to scrap.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, a kind of thin-walled parts turning accessory is provided, it can adjust the lathe tool position automatically with the variation of workpiece axiality or wall thickness, avoids occurring phenomenons such as car is worn or wall unevenness is even, has improved the qualification rate of workpiece.
For achieving the above object, thin-walled parts turning accessory of the present utility model, comprise support, it is characterized in that also comprising the pedestal that connects firmly with support, pedestal comprises a biside plate and a base plate, one slide block is set in the pedestal, be equipped with the spring more than two or two between slide block and the side plate, be fixed with prelocalization seat and back positioning seat on slide block, a power transmission shaft is loaded on prelocalization seat and the back positioning seat by bearing, and a small tool is loaded on the power transmission shaft between two positioning seats and places on the slide block, small tool and power transmission shaft are provided with the fit screw rod screw thread pair, small tool is provided with step, is fixed in the fit upper surface of this step of pressing plate on the slide block, and lathe tool is loaded on the small tool; One end of power transmission shaft connects with a positioning seat, and the other end connects with a handwheel; Also be installed with mandrel on the positioning seat therein, mandrel is provided with roller.
During use, support is installed on the knife rest of lathe, roller contacts with the outer surface or the inner surface of workpiece, and the center of nose center and workpiece regulated contour after, adjust lathe tool accordingly and contact with the inner surface or the outer surface of workpiece, can process; When the axiality of workpiece or wall thickness changed, roller and lathe tool be synchronously along the moving radially of workpiece, guaranteed processing back workpiece evenly, improved the qualification rate of workpiece.

Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the left view (partial cutaway) of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
By Fig. 1, Fig. 2 and shown in Figure 3, this thin-walled parts turning accessory, comprise support 1, the pedestal 2 that connects firmly by screw with support 1, pedestal 2 comprises a biside plate 2a and a base plate 2b, one slide block 3 is set in the pedestal 2, be equipped with two springs 4 between slide block 3 and the side plate 2a, on slide block 3, be fixed with prelocalization seat 5 and back positioning seat 6 by screw, one power transmission shaft 7 is loaded on prelocalization seat 5 and the back positioning seat 6 by bearing, one small tool 8 is loaded on the power transmission shaft 7 between two positioning seats 5 and 6 and places on the slide block 3, small tool 8 is provided with fit screw rod-screw thread pair with power transmission shaft 7, small tool 8 is provided with step, be fixed in the fit upper surface of these steps of pressing plate 9 on the slide block 3 by screw, lathe tool 10 is loaded on the small tool 8; One end of power transmission shaft 7 and prelocalization seat 5 are by screw attachment, and the other end connects by bearing pin 12 with a handwheel 11; Also be installed with mandrel 13 on the positioning seat 6 of back, mandrel 13 is provided with roller 14.
During use, support 1 is installed on the knife rest of lathe, and regulate height, make that lathe tool 10 nose center are consistent with the center of workpiece, roller 14 is adjacent to the outer surface or the inner surface of workpiece, and can rotates with workpiece by pad; Rotate handwheel 11 again, drive small tools 8 along the moving radially of workpiece, adjust lathe tool 10 and correspondingly contact, can process with the inner surface or the outer surface of workpiece by power transmission shaft 7; Slide block 3 and the part on it become unsteady system, when the axiality of workpiece or wall thickness change, workpiece pair roller 14 produces pressure, roller 14 drive slide blocks 3 and on lathe tool 10 moving radially synchronously along workpiece, guarantee the even of processing back workpiece, improved the qualification rate of workpiece; After the pressure of workpiece pair roller 14 disappeared, slide block 3 resetted under the effect of spring 4, and drove roller 14 and continue to be adjacent to workpiece, provided support to workpiece; Pressing plate 9 can be prevented that limited slip block 3 produces and beats longitudinally, guarantees machining accuracy.
