Abstract
The utility model discloses a fixed follow rest, including big layer board, the follow rest main part is installed to big layer board, be equipped with the work piece in the follow rest main part and hold in the palm the device. Because the main body of the follow rest is fixed on the large supporting plate to support the workpiece; the cutter is fixed on the large supporting plate through the cutter frame plate, the small supporting plate and other parts, when the large supporting plate moves, the cutter and the follow-up rest correspondingly move together with the large supporting plate, and the distance between the cutter and the follow-up rest is kept relatively fixed. Therefore, the phenomenon that the distance between the supporting point of the workpiece and the cutter is gradually increased to cause that the cutting force causes the deformation and the vibration of the workpiece to be increased is avoided; therefore, the problems of unfitness, ellipse, knife tremble and the like on the surface of the workpiece during machining are avoided, the qualified rate of the workpiece is correspondingly improved, and the cost of enterprises is reduced.
Description
Technical field
The utility model relates to a kind of fixedly follow-rest, and especially a kind of lathe is follow-rest fixedly.
Background technology
Usually run into long and the workpiece that external diameter is less of some Workpiece lengths in the turning process, processing need guarantee that workpiece blank stretches out the chuck outside.When processing work, along with moving of cutter, the strong point of workpiece and cutter strengthen gradually apart from meeting and cause cutting force that workpiece deformation is strengthened, vibrations strengthen, finished surface can produce not only or problems such as ellipse, the cutter that quivers, even causes scrapping of workpiece, thereby has also increased the cost of enterprise.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of a kind of fixedly follow-rest that can be maintained fixed distance man-hour with cutter that adds.
The technical scheme that its technical problem that solves the utility model adopts is:
Fixing follow-rest, it is characterized in that: comprise big palette, the follow-rest main body is installed on the described big palette, described follow-rest main body is provided with the workpiece backing device.
The workpiece backing device comprises guide pin bushing, guide pin bushing lining ring, guide pin bushing lining ring nut, guide pin bushing nut, and the guide pin bushing lining ring is contained in the guide pin bushing installing hole, is locked together by guide pin bushing lining ring nut and follow-rest main body, and described guide pin bushing is fixed in the guide pin bushing lining ring by the guide pin bushing nut.
Guide pin bushing one end is provided with extended gripper jaw, and gripper jaw can tighten up by the extruding of guide pin bushing lining ring.
Described follow-rest main body is a herringbone structure, is respectively equipped with the knife rest bottom outlet on the herringbone bipod.
Described follow-rest main body is installed on the big palette by the knife rest bottom outlet.
Described knife rest bottom outlet is a waist typed through hole.
The beneficial effects of the utility model are: because the follow-rest main body is fixed on big palette upper support workpiece; Cutter is fixed on the big palette by parts such as knife rest plate, little supporting plates, and during the big palette motion, cutter moves with big palette accordingly with follow-rest, and the distance between them keeps relative fixed.With regard to the strong point of having avoided workpiece and the cutter distance strengthens gradually and cause cutting force that workpiece deformation is strengthened, vibrations strengthen like this; Thereby also avoided can producing not only or some problems such as ellipse, the cutter that quivers on the surface that adds the workpiece in man-hour, the qualification rate of workpiece also can correspondingly improve, thereby has also reduced the cost of enterprise.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the exploded pictorial view of fixedly follow-rest;
Fig. 2 is the fixing whole schematic views of follow-rest.
The specific embodiment
See figures.1.and.2, a kind of fixedly follow-rest provided by the utility model comprises big palette 1, and cutter is fixed on the big palette 1 by parts such as knife rest plate, little supporting plates, and big palette 1 assembly as a whole can move back and forth on the y direction of lathe.Follow-rest main body 2 is installed on the big palette 1, and follow-rest main body 2 is provided with the workpiece backing device.The workpiece backing device comprises guide pin bushing 21, guide pin bushing lining ring 22, guide pin bushing lining ring nut 24, guide pin bushing nut 25.Wherein guide pin bushing lining ring 22 1 ends have boss, and TOE, guide pin bushing lining ring 22 are installed in the guide pin bushing installing hole 233, by guide pin bushing lining ring nut 24 guide pin bushing lining ring 22 are fixed on the follow-rest main body 2.Described guide pin bushing 21 is fixed in the guide pin bushing lining ring 22 by guide pin bushing nut 25.Guide pin bushing 21 1 ends are provided with extended gripper jaw 211, gripper jaw 211 is the taper type face towards the face of guide pin bushing lining ring 22 1 sides, corresponding with guide pin bushing lining ring 22, and the diameter of this taper type is greater than the internal diameter of guide pin bushing lining ring 22, therefore when adjusting the position of guide pin bushing 21 guide pin bushing lining ring 22 in, gripper jaw 211 can push by guide pin bushing lining ring 22 and tighten up.When tightening up guide pin bushing nut 25, guide pin bushing lining ring 22 press nip pawls 211, the active force of 211 pairs of workpiece of gripper jaw strengthens; Loosen guide pin bushing nut 25, the extruding of 22 pairs of gripper jaws 211 of guide pin bushing lining ring alleviates, and the active force of 211 pairs of workpiece of gripper jaw reduces, and the tightness in the time of adjusting gripper jaw 211 holding workpieces like this is to guarantee that workpiece can be free to slide in guide pin bushing 21.
As shown in the figure, follow-rest main body 2 is herringbone, respectively be provided with a knife rest bottom outlet 231 on the bipod of bottom, follow-rest main body 2 links to each other with big palette 1 by knife rest bottom outlet 231, knife rest bottom outlet 231 is a waist typed through hole especially, this waist typed through hole can allow follow-rest 23 move up and down and do certain fine setting, and can guarantee like this that workpiece is packed guide pin bushing 21 into can be coaxial during with anchor clamps 3.
The workman adds man-hour carrying out turning, and an end of workpiece is fixed in the anchor clamps 3, and the other end passes from dowel hole 212, adjusts the tightness of gripper jaw 211 holding workpieces then, and workpiece can be free to slide in dowel hole 212.When cutter moved, follow-rest moved with cutter by the parts such as knife rest plate that are contained on the big palette 1, and the distance between cutter and the follow-rest keeps relative fixed.Strengthen gradually with regard to the distance of the strong point of having avoided workpiece and cutter like this and cause cutting force that workpiece deformation is strengthened, vibrations strengthen, thereby have also avoided therefore causing surface of the work not only or oval, cutter some problems such as cutter of quivering.
