Abstract
An umbrellalike overloading active finial comprises an umbrellalike seat shell (4), a top cover (1), a taper shank axes (9) and a press cover (8), wherein the umbrellalike seat shell (4) is supported on the taper shank axes (9) by a cylindrical roller bearing (2), a thrust ball bearing (3) and a deep groove ball bearing (5) directly; the taper shank axis (9) is provided with a taper face which is arranged in a support seat of the machine tool; an umbrellalike face acts on the cylindrical roller bearing (2) and the deep groove ball bearing (5) directly; an axial cutting force is born by the thrust ball bearing. The utility model gets rid of the astriction of the prior technique without the influence of the size of the machine tool finial support seat and jacks the big caliber pipe material directly with the umbrellalike active finial to free from the trouble that each pipe diameter must be provided with a pair of ''close head'', which saves the time of the prior technique to repeat to adjust the radialis pendulum of the work excircle; The economic benefit is remarkable.
Description
Technical field
The utility model relates to heavy roll plant equipment, is used for heavy roll a kind of umbrella shape heavy duty live center mechanically specifically.
Background technology
At present, the top back dead centre that mostly is on the market on the used roll plant equipment, though in recent years the live center technology had been used on the roll plant equipment, it mostly is mini-plant, for needed live center on the large-scale roll plant equipment, existing live center technology also is difficult to satisfy the requirement that processing was got off, ground in heavy duty, its problem is to use the life-span short, and stock-removing efficiency is low, and machining accuracy is poor, can't satisfy the needs that enterprise produces, restrict the development of enterprise.Particularly existing umbrella shape live center is that the head at original live center adds a umbrella sleeve in addition, because the umbrella shape cantilevered is enclosed within foremost top, only be attached thereto, cause supporting stable inadequately, and the more difficult realization of undersized taper shank be to the supporting of big umbrella cover with a short conical surface.
Summary of the invention
The utility model is the deficiency that solves the problems of the technologies described above, and according to the top stressed characteristics of umbrella shape, has carried out reasonable assembly in umbrella shape inside, is intended to solve umbrella shape live center load-bearing capacity and best force-bearing situation.
The utility model is the deficiency that solves the problems of the technologies described above, the technical scheme that is adopted is: a kind of umbrella shape heavy duty live center, form by umbrella shape seat shell, top cover, taper-shank arbor, gland, umbrella shape seat shell directly is supported on the taper-shank arbor by cylinder roller bearing, thrust ball bearing, deep groove ball bearing, taper-shank arbor is provided with and cooperates the conical surface that is installed in the lathe bearing, the umbrella shape face directly acts on cylinder roller bearing and the deep groove ball bearing, and axial cutting force is born by thrust ball bearing.
The utility model is provided with a boss on gland, the decrement of the Height Adjustable disk spring that gland protrudes.
The utility model is provided with disk spring between gland and deep groove ball bearing, thereby reach the purpose of regulating preload, preload is by deep groove ball bearing and owing to the limited step on the taper-shank arbor acts on the thrust ball bearing, so can preventing thrust ball bearing, separates deep groove ball bearing, shared simultaneously the part radial load of cylinder roller bearing again, very bearing capacity and the service life that helps improving cylinder roller bearing.
Top cover of the present utility model is arranged on the top of the cylinder roller bearing in the umbrella shape, because the top cover that is provided with makes all bearings be in sealing state, has played the effect that prevents that lubricating grease from revealing effectively.
It is low that the utility model also has a cost, machining accuracy height, good reliability, the characteristics of long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark among the figure: 1, top cover; 2, cylinder roller bearing; 3, thrust ball bearing; 4, umbrella shape seat shell; 5, deep groove ball bearing; 6, disk spring; 7, screw; 8, gland; 9, taper-shank arbor.
The specific embodiment
Thrust ball bearing 3 and cylinder roller bearing 2 are contained on the taper-shank arbor 9, and in the umbrella shape seat shell 4 of again said modules being packed into, the deep groove ball bearing 5 of then packing into, disk spring 6 are contained in gland 8 on the umbrella shape seat shell 4 with screw 7, cover top cover 1.
The utility model is not subjected to the influence of the top supporting stand size of lathe, is a kind of live center of innovative big umbrella cover.
The utility model has been broken away from the constraint of traditional handicraft, and the large-diameter pipe material with umbellate form live center direct top car, has been removed the trouble that every kind of caliber must be equipped with a pair of " silently ".
The utility model has been saved old technology time of centering work outer circle diameter pendulum repeatedly, remarkable in economical benefits greatly.
