Detailed description of the invention
Detailed description of the invention one: composition graphs 1 to Figure 10 illustrates present embodiment, present embodiment comprise hold-down screw 1, dog screw 2, fixing body 3 and mandrel 4; Mandrel 4 is positioned at the right-hand member of fixture, and mandrel is axial workpiece.Mandrel 4 is the end cylindrical 4-3 of side and the second endoporus 3-3 matched in clearance of fixing body 3 greatly, cylindrical 4-3 is provided with the first screwed hole 4-4, first screwed hole 4-4 coordinates with the screw thread 2-1 of dog screw 2, the small end of mandrel 4 is taper seat 4-2, taper seat 4-2 coordinates with the internal control of tail stock sleeve, ensures mandrel axis and lathe spindle dead in line.Be provided with a square boss 4-1 at cone small end, with the locating slot matched in clearance in tail stock sleeve, play circumferential positioning action, when preventing mandrel stressed, circumference is rotated.Fixing body 3 is axial workpiece, and inside has shoulder hole, the second endoporus 3-3 and mandrel cylindrical 4-3 matched in clearance, ensures that fixing body can axially be free to slide.Fixing body 3 is provided with elongated slot 3-5, elongated slot 3-5 and dog screw 2 periphery 2-2 matched in clearance, ensures that fixing body can axially be free to slide.After fixing body and mandrel are assembled, the first screwed hole 4-4 of the elongated slot 3-5 on fixing body 3 and mandrel 4 aligns, and revolve 2 in the first screwed hole 4-4 with dog screw, dog screw plays the role of positioning, and when preventing fixing body stressed, circumference is rotated.Dog screw 2 greatly end has groove 2-4, is handling instrument groove.Fixing body 3 other end first endoporus 3-1 diameter is greater than the diameter of the second endoporus 3-3.Fixing body has circular hole 3-4, and circular hole 3-4 is corresponding with elongated slot 3-5, and circular hole 3-4 is chip-removal hole.Chip-removal hole down when mounted, and the chip that machining screw is produced is discharged from hole 3-4 automatically.The circumference of the first endoporus 3-1 is provided with four the second screwed hole 3-2, and the second screwed hole 3-2 coordinates with hold-down screw 1.
Detailed description of the invention two: composition graphs 1 to Figure 10 illustrates present embodiment, the length of the periphery 2-2 of the dog screw 2 of present embodiment is greater than the wall thickness of the elongated slot 3-5 of fixing body 3, fixing body can slide axially, and other composition is identical with detailed description of the invention one with annexation.
Detailed description of the invention three: composition graphs 1 to Figure 10 illustrates present embodiment, the first endoporus 3-1 diameter of fixing body 3 one end of present embodiment is greater than the diameter of the second endoporus 3-3.The screw die of threading is contained in fixing body first endoporus 3-1, fixes screw die with hold-down screw, and other composition is identical with detailed description of the invention one with annexation.
The course of work:
When Vehicle Processing parts fixation on lathe, fixture mandrel cone one end is arranged in tail stock sleeve, and pin prevent mandrel from coming off in sleeve, screw die is contained in the large end endoporus of fixing body.
Lathe spindle drives workpiece to rotate, and make screw die align workpiece hitch with pulling fixing body, because fixing body can slide axially, screw die moves from trend lathe spindle direction in workpiece rotary course, completes the processing of screw thread.After processing screw thread, lathe spindle reverses, and screw die moves from trend tail stock direction, and screw die completes screw thread process after departing from workpiece.
Foregoing is only preferred embodiment of the present utility model; not for limiting embodiment of the present utility model; those of ordinary skill in the art are according to central scope of the present utility model and spirit; can carry out corresponding flexible or amendment very easily, therefore protection domain of the present utility model should be as the criterion with the protection domain required by claims.
