Abstract
The utility model relates to a special turning device used for processing super elongated threaded rods, which is composed of a tracking central frame and a rotating clamping apparatus, wherein the tracking central frame is composed of a frame body, an adjustable central sleeve and an adjusting threaded rod. The rigidity and the processing precision of the whole technology system can be improved by adopting the device, so satisfactory processing effect and considerable economic benefit can be obtained.
Description
The utility model belongs to the machine-building processing technique field.
The processing method commonly used of slender axles and elongate threaded screw has two kinds, and a kind of is the rip cutting formula, promptly on rip cutting formula lathe cutter is fixed, and makes workpiece along axial-movement, to realize machining.Second method is to adopt follow-rest on engine lathe, uses general Tool in Cutting.Because the rigidity of slender axles own is poor, in process distortion bigger, thereby can not guarantee machining accuracy, and production efficiency is also lower.And first method needs expensive special-purpose rip cutting formula lathe, is difficult to promote.
The purpose of this utility model is to utilize common engine lathe, is aided with special device, to realize the high efficiency processing of accurate ultra-fine long bolt.
The isolated plant of the utility model design is mainly formed by following the tracks of centre frame 5 and rolling clamp 8, following the tracks of centre frame is installed on the carriage box of lathe, replaced original follow-rest, so just having overcome the lathe centre frame can not move, and the low shortcoming of follow-rest rigidity.Follow the tracks of centre frame by support body 12, interchangeable center 10 and adjustment screw rod 11 are formed, and the internal diameter size of interchangeable center is decided according to axle class external diameter, and its gap can be changed at any time for movingly, clamp with adjusting screw rod.Forming-tool will be contained on the knife rest, in turning process, follow the tracks of centre frame and forming-tool and remain fixing distance, following the tracks of centre frame entangles the axial workpiece external diameter, when forming-tool is given workpiece cutting force, this is advocated and will be offset by interchangeable center in the tracking centre frame, thereby has overcome the distortion of radial load to axostylus axostyle.Owing to adopted interchangeable center 10 to replace three cast irons on the former centre frame to prop up pawl on the tracking centre frame, becoming original supported at three point is that face supports, thereby has increased substantially the rigidity of whole process system.Rolling clamp 8 is installed on the tailstock, is used for vertically straining workpiece, prevents distortion.The application of rolling clamp has changed the stress of workpiece in working angles, has further improved system stiffness, can boost productivity significantly, and realize the processing of micron order.
Adopt the isolated plant of the utility model design, can process diameter phi 0.5～φ 6mm on engine lathe, draw ratio surpasses 500 the accurate screw rod of ultra-fine length, and its precision index is: roughness
7, garden degree 0.02, production efficiency can improve about 15 times.
Fig. 1 is for following the tracks of centre frame and the scheme of installation of rolling clamp on lathe, 1 forming-tool among Fig. 1,2 knife rests, 3 headstocks, 4 chucks, 5 tracking centre frames, 6 carriage box, 7 workpiece, 8 rolling clamps, 9 tailstocks.
Fig. 2 is for following the tracks of the profile of centre frame, 10 interchangeable center among the figure, 11 adjustment screw rods, 12 support bodys.
Claims (1)
1, a kind of turning isolated plant that is used for the ultra-fine long bolt of processing precise, it is characterized in that this device forms by following the tracks of centre frame and rolling clamp, replace original follow-rest with the tracking centre frame, follow the tracks of centre frame by support body, tunable center cover and adjustment screw rod constitute, and the internal diameter size of tunable center cover is decided according to the workpiece external diameter, its gap is for movingly, rolling clamp is installed on the tail stock, follows the tracks of centre frame and is installed on the carriage box, is maintained fixed distance with forming-tool.
