Abstract
The utility model relates to a screw lathe, aiming to solve the difficulties in processing internal hole on the end face of slight component. The utility model is provided with a lathe used for processing the internal hole on the the end face of the slight component; in the lathe, a lathe head of a headstock is arranged in the middle of the lathe bed, a lathe tail is arranged on the upper left of the lathe bed, and a knife rest is arranged on the upper right of the lathe bed. When being processed, the workpiece passes through the main axis hole of the lathe head of the headstock, making the process end of the workpiece clipped on a chuck of the lathe head, close to the knife rest arranged on the upper right of the lathe bed; the other end of the slight workpiece is supported by a thimble of the leftward lathe tail. The utility model needs no center rest, and the workpiece can not swing, thereby having the advantages of convenient process, in addition, increasing processing precision.
Description
Technical field
The utility model relates to Metal Cutting Machine Tool, particularly screw cutting lathe.
Background technology
A kind of length is the thin and long units of diameter more than 10 times, and its end face endoporus is processed puzzling mechanical technology personnel and workpeople always, has become the problem that is difficult to capture.For example, the end face internal thread machining of steam turbine stay bolt part all is to operate on engine lathe usually.Traditional engine lathe that people know, its structure be knife rest between the main spindle box head of a bed and tailstock, an end of workpiece is clamped by the chuck of the main spindle box head of a bed, because of workpiece elongated, the other end at workpiece need use centre frame to make supporting fixture, rocks to prevent workpiece, but can not hold too tight.Because the claw of centre frame and the surface of the work friction of being supported cause that the claw wearing and tearing are very fast, workpiece is loosening easily, and the axle center is offset thereupon, and vibration is big, has influenced machining accuracy, and time-consuming, and work efficiency is lower.
Summary of the invention
The utility model has overcome that the axle center is offset easily in the thin and long units processing, the defective of processing dimension shakiness, can prevent the workpiece swing effectively, improves machining accuracy.
The utility model is to realize by following technical scheme, it comprises lathe bed, the main spindle box head of a bed, knife rest, tailstock, motor, transmission mechanism, carriage box, feed change, polished rod, screw mandrel, its structural feature is that the upper left quarter of this body of lathe bed has interior guide rail, upper right quarter has outer guide, the middle upper part of lathe bed is provided with the main spindle box head of a bed, middle below is provided with transmission mechanism, the left lathe bed guide rail that is positioned at the main spindle box head of a bed is provided with tailstock, and the right-hand lathe bed outer guide that is positioned at the main spindle box head of a bed is provided with knife rest.
The utility model is with the main spindle box head of a bed of normal screws lathe, knife rest, the tailstock position changes, be designed to the special purpose lathe of energy processing slim part end face endoporus, making thin and long units process an end directly clamps with the chuck of the main spindle box head of a bed, the other end is supported by the tailstock thimble, the chuck distance of the knife rest and the main spindle box head of a bed is approaching, need not to use centre frame, reduced swing, made things convenient for processing, machining accuracy and work efficiency have been improved, solved thin and long units end face endoporus processing problems, especially overcome wear and tear easily skew and cause the size shakiness of centre frame during machining screw, defective such as must repeatedly measure, adopted the utility model machining internal thread to impose uniformity without examining individual cases, improve the work efficiency several times, for mechanical processing industry has increased a kind of special purpose machine tool equipment.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among Fig. 1, the upper left quarter of lathe bed 1 has interior guide rail 2, upper right quarter that outer guide 6 is arranged, the lathe bed middle upper part is equipped with the main spindle box head of a bed 4, transmission mechanism 8 is equipped with in middle below, tailstock 3 is equipped with on the upper left side of lathe bed 1, tailstock 3 can move along guide rail in the lathe bed 2, and knife rest 7 is equipped with in the upper right side of lathe bed 1, and the planker of knife rest 7 can move along lathe bed outer guide 6.When processing slim part end face endoporus, present embodiment is a processing vapor turbine king-bolt end face internal thread, this workpiece is passed the spindle hole of the main spindle box head of a bed 4, clamp processing one end of workpiece by the chuck 5 of the main spindle box head of a bed 4, the other end of slender bolt is by the thimble supporting of tailstock 3, to prevent the workpiece swing, the close together of knife rest 7 and chuck 5, thereby do not need to use centre frame, and both made things convenient for processing, improved machining accuracy again.
Claims (1)
