Abstract
The utility model relates to a two-purpose rotating centre which is a necessary tool for turning machines, grinding machines and other machine tools, belonging to the field of a machine work tool. The utility model is composed of a center, an umbrella body and a circlip, wherein, the umbrella body is sheathed on the center in the way of screw connection; the front part of the umbrella body is provided with the circlip. The utility model has the advantages of one machine with dual-purpose, combined whole body of centers with two properties, convenient assembly and disassembly and low cost.
Description
The utility model belongs to the machinery tools field, is the indispensable instrument of lathe, grinding machine and other lathe.
At present domesticly toply be divided into stationary center, live centre substantially and stir top three major types type.Light live centre and umbrella shape are top in being divided into again in live centre.Light duty live center in must using during the machined into shaft-like workpiece is if must use umbrella shape top when processing hollow shaft and tubing workpiece.Two kinds of top purposes are had nothing in common with each other, and are indispensable, thus lathe must have two kinds top, could satisfy the needs of different workpieces processing.The top there be limited evidence currently of of umbrella shape has manufacturer production, all is to be designed voluntarily and made by enterprise, problem of poor quality, that cost is high occurred.Quality and precision that the umbrella shape of each enterprise's self design is top all vary, and do not reach due precision.
The purpose of this utility model is exactly with top being combined as a whole double-duty, and it is dual-purpose to form a point, thereby provides convenience to the operator, has saved again simultaneously and has purchased two kinds of top expenses, has improved the scope of application of live centre.
The utility model is made of top, umbrella body and jump ring, and umbrella body is sleeved on top going up and connects with thread forms.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the working shaft-like workpiece schematic diagram;
Fig. 3 is processing tubing workpiece schematic diagram.
Below in conjunction with the description of drawings the technical solution of the utility model.
(1) is that 60 degree are top among the figure, and (2) are jump ring, and (3) are umbrella body, and (4) are tail stock, and (5) are workpiece.
Screw thread is processed at 38 millimeters places of 60 degree top (1) φ, again umbrella body (3) is sleeved on top (1) and goes up,, on top (1) of umbrella body (3) front end, add a jump ring (2) for avoiding the loosening slow button of umbrella body (3) with being threaded.
The utility model dual-use, umbrella body connects with thread forms, and the top of two kinds of performances is combined as a whole, and decomposes in conjunction with convenient, and be top with 60 degree during working shaft-like workpiece, just top with 90 degree umbrella shapes when processing tubing workpiece.
The utility model is easily manufactured, and technology is simple, and is with low cost, has great practical value.
Claims (2)
1, a kind of dual-purpose live centre is characterized in that by top (1), umbrella body (3) constitutes, and umbrella body (3) is sleeved on top (1) and goes up with being threaded.
2, dual-purpose live centre according to claim 1 is characterized in that being added with jump ring (2) on top (1) of umbrella body (3) front end.
