Abstract
The invention relates to an improved tip which comprises a movable tip, a clamp body and a retainer. A guide groove is formed in the clamp body, the movable tip is arranged in the guide groove, a spring is arranged between the bottom of the guide groove and the tail portion of a tip rod, a floating disc arranged on the movable tip in a sleeving mode is further arranged on the clamp body and connected with the clamp body through the retainer, a small hole and a spiral groove which are mutually communicated are formed in the tip head at the head portion of the movable tip, and a guide hole communicated with the small hole is further formed in the movable tip. The improved tip has the advantages of being simple in structure, long in service life, capable of reducing abrasion and meanwhile ensuring radial run-out of parts, end face run-out and turning allowance of the end faces, and the like.
Description
Technical field
The present invention relates to field of mechanical technique, particularly a kind of modified is top.
Background technology
Lathe, when processing work, in order to ensure precision and the axiality of workpiece, all can be installed one at lathe tail end and toply withstanding workpiece.In process, because the high-speed rotary change of team of workpiece makes workpiece tail end and top contact position wear and tear, reducing top service life, there is axial runout, the precision of reduction workpiece adding in the serious workpiece that also will make man-hour.The machining allowance of the circular runout of shaft-disc type component, end face run-out and end face thereof cannot be ensured by traditional locate mode simultaneously.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of structure simple, reduce wear, long service life, can ensure simultaneously the circular runout of part, end face run-out and end face thereof the modified of machining allowance top.
Realize technical scheme of the present invention as follows:
A kind of modified is top, comprise live center, clamp body and retainer, described clamp body is provided with gathering sill, and live center is arranged in gathering sill, is provided with spring between the bottom of gathering sill and the afterbody of top bar, clamp body is also provided with the floating disc be set on live center, floating disc is connected with clamp body by retainer, and described live center head centre head has the aperture and helicla flute that are interconnected, and live center inside is also provided with the pilot hole be connected with aperture.
On described floating disc, both ends of the surface are respectively equipped with two ribs, these two ribs are vertically arranged mutually, also can be other angles, a wherein rib and clamp body end contact, the end contact of another rib and workpiece, advantage is can so that positioning workpieces, also can debug, to ensure that the circle of workpiece end face is beated before location simultaneously.
Described floating disc is also provided with installing hole, the pin for fixing floating disc is provided with in installing hole, pin interts floating disc, then the end face of straight cutting clamp body, the end face of this clamp body is provided with the fixing hole adapted with pin, is convenient to fixing pin, thus reaches fixing floating disc, this fixing hole is provided with multiple and is roundedly distributed on clamp body end face, and advantage is to be fixed by the floating disc after adjustment.
Have employed above-mentioned scheme, the gathering sill arranged in clamp body is connected by spring with live center, is convenient to by the different control realized live center of the decrement of spring; It is overproof that the arranging of floating disc can eliminate beating of the processing end face caused because Workpiece fixing end face run-out is overproof, simultaneously also can work in-process with floating disc end face for positioning datum, effectively ensure that uniformity and the chipping allowance of Workpiece fixing end face; Floating disc is connected with clamp body by retainer, ensure that the fixing of position, prevents its displacement from producing deviation; Pilot hole in live center is built with lubricating oil, and due to pilot hole, aperture and helicla flute communicate, and lubricating oil can pass straight through to surface and the absorption surface of live center, effectively decreases workpiece and top wearing and tearing, improves the service life of production efficiency and live center.

Fig. 1 is structural representation of the present invention;
Fig. 2 is the sectional view of live center in the present invention;
Fig. 3 is the front view of floating disc in the present invention;
Fig. 4 is the left view of Fig. 3;
In accompanying drawing, 1 is clamp body, and 2 is gathering sill, and 3 is live center, and 4 is spring, and 5 is floating disc, and 6 is retainer, and 7 is rib, and 8 is pilot hole, and 9 is aperture, and 10 is helicla flute, and 11 is pin, and 12 is installing hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As shown in Figure 1 to Figure 4, a kind of modified is top, comprise live center 3, clamp body 1 and retainer 6, described clamp body 1 is provided with gathering sill 2, live center 3 is arranged in gathering sill 2, the bottom of gathering sill 2 and or top 3 afterbody between be provided with spring 4, clamp body 1 is also provided with the floating disc 5 be set on live center 3, floating disc 5 is connected with clamp body 1 by retainer 6, described live center 3 head centre head has the aperture 9 and helicla flute 10 that are interconnected, and live center 3 inside is also provided with the pilot hole 8 be connected with aperture 9.
On described floating disc 5, both ends of the surface are respectively equipped with two ribs 7, these two ribs 7 are mutually vertical to be arranged, also can be other angles, a wherein rib and clamp body end contact, the end contact of another rib and workpiece, simultaneously advantage so that positioning workpieces, also can debug, to ensure that the circle of workpiece end face is beated before location.
Described floating disc 5 is also provided with installing hole 12, the pin 11 for fixing floating disc 5 is provided with in installing hole 12, pin 11 interts floating disc 5, then the end face of straight cutting clamp body 1, the end face of this clamp body 1 is provided with the fixing hole adapted with pin 11, is convenient to fixing pin 11, thus reaches fixing floating disc 5, this fixing hole is provided with multiple and is roundedly distributed on clamp body 1 end face, and advantage is to be fixed by the floating disc 5 after adjustment.
During use, one live center location, workpiece is installed, during Workpiece clamping, hand spring pressure compresses, live center retraction is until Workpiece fixing end face leans against on floating disc, during clamping, on floating disc two ribs respectively with clamp body surface contact and Workpiece fixing end contact, when Workpiece fixing end face run-out is overproof, floating disc rotates the rib on floating disc according to the height of Workpiece fixing end face, Workpiece fixing end contact is contacted completely with rib, thus it is overproof to eliminate beating of the processing end face caused because Workpiece fixing end face run-out is overproof, locate with floating disc end face in processing simultaneously, ensure that the uniformity of Workpiece fixing end face and the chipping allowance of workpiece end face.
