Abstract
A lathe center comprises an assembling shaft, a tip and a gland, wherein the tip is a cone, and the top of tip is a smooth end surface; one end of the assembling shaft is inserted into a stepped hole at the large end of the tip and is connected with the tip by bearings, the other end of the assembling shaft is arranged on the lathe, and the gland is arranged at the outer side of the bearings; as a preferable scheme, the tip and the assembling shaft by two bearings arranged at an interval; and the stepped hole inside the tip is a through hole. The lathe center is convenient to install, easy to realize and high in generality; and as the general center of the lathe is replaced by the conical tip with a plane top end, and the tip is connected with the assembling shaft by the two bearings, steel pipes with various specifications can be effectively clamped by the matching of the tip and a chuck of the lathe, and the production efficiency and the quality of products are improved.
Description
Technical field
The utility model relates to lathe accessories, is specifically related to a kind of lathe centre.
Background technology
The steel pipe that is used for producing oil cylinder need carry out chamfer machining before welded flange, when adopting engine lathe to carry out chamfer machining, need be clamped in steel pipe one end on the chuck; Another section withstands with the top of tail stock; Because the specification specification of steel pipe to be processed does not wait from Φ 60-Φ 220, and the external diameter maximum of engine lathe tailstock centre has only Φ 40, so top top is less than steel tube inner hole; Can not play the effect of effective clamping; And steel pipe is long is clipped on the chuck owing to receive gravity effect can produce amount of deflection, causes and beats, and can't carry out operations.
The utility model content
The utility model provides a kind of lathe centre, and it is little to have solved the top scope of application of engine lathe, to the effective problem of clamping of large diameter steel pipe.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of lathe centre comprises assembled shaft, top and gland, and said top is a cone; The top is a flat end face, and said assembled shaft one end inserts the shoulder hole of the big end in top, and is connected through bearing between the top; The other end is installed on the lathe, and gland is equipped with in the bearing outside.
As a preferred version, two bearings are installed at interval between said top and the assembled shaft.
As further preferred version, the shoulder hole in the said top is a through hole.
The utility model is easy for installation, be easy to realize, uses the top to replace the general top of lathe as the centrum top on plane, and passes through two bearings and be connected with assembled shaft; The top cooperates the chuck of lathe to realize effective clamping of plurality of specifications steel pipe, and the gland in the bearing outside can compress bearing, axial motion can not occur when guaranteeing shaft strength; Be provided with through hole in top, be convenient to the dismounting of bearing, make top versatility stronger; Reduce production cost, improved production efficiency and product quality.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the utility model overall structure sketch map;
Among the figure:
1, assembled shaft; 2, gland; 3, screw; 4, top; 5, bearing.
The specific embodiment
As shown in Figure 1; Provided a specific embodiment of the utility model, among the figure, top 4 is a cone; The top is a flat end face; The shoulder holes of assembled shaft 1 one ends insertion top 4 big ends are connected with the bearings of installing through two intervals between the top 45, and bearing 5 outsides are equipped with gland 2 and are fixedly mounted on the top 4 through screw 3.Add come directly towards man-hour 4 stressed nearly all on the Internal and external cycle of bearing 5, avoid coming directly towards 4 with the dry friction of steel pipe, use prolong greatly service life, and make the concentricity of top 4 be able to guarantee through the location, outer ring of two pairs of bearings.
The utility model is easy for installation, be easy to realize, uses the top to replace the general top of lathes as the centrum top 4 on plane, and passes through two bearings 5 and be connected with assembled shaft 1; Top 4 cooperates the chuck of lathe to realize effective clamping of plurality of specifications steel pipe; The gland 2 in bearing 5 outsides can compress bearing 5, guarantees that bearing 5 axial motion can not occur when stressed, is provided with through hole in the top 4; Be convenient to the dismounting of bearing 5; Make top versatility stronger, reduced production cost, improved production efficiency and product quality.
Claims (3)
1. a lathe centre comprises assembled shaft, top and gland, it is characterized in that, said top is a cone, and the top is a flat end face, and said assembled shaft one end inserts the shoulder hole of the big end in top, and is connected through bearing between the top, and gland is housed outside the bearing.
2. a kind of lathe centre according to claim 1 is characterized in that, two bearings are installed between said top and the assembled shaft at interval.
