Abstract
The utility model relates to a polished rod suspension device for leading a polished rod to keep balance and normal work operation when a machine tool polished rod operates a machine tool, comprisinga guide rail plane moving device, a connecting rod, a set of operating bearing and the polished rod (5), wherein the guide rail plane moving device comprises a support frame (10) which is groove-shaped and has a downward groove opening; the inner wall surface of the support frame (10) is compounded with a bakelite wear-resistant lining (9); the connecting rod (8) is downwards and vertically arranged at the outer side of the support frame (10); the upper end of the connecting rod (8) is fixedly connected with the outer side of the support frame (10), and the lower end thereof is welded with theset of operating bearing; the operating bearing comprises a shaft sleeve (1) and a bearing (2); the shaft sleeve (1) is sheathed on the polished rod (5); the shaft sleeve (1) is connected with the polished rod (5) by a key (4); the bearing (2) is sheathed on the shaft sleeve (1); and the outer edge of the bearing (2) is provided with an oil hole (6). The polished rod suspension device can solve the problem of relatively fixing of the polished rod when normal operation of the machine tool is guaranteed in the process of production work.
Description
(1) technical field
The utility model relates to a kind of normal device that uses of lathe that keeps, and particularly the lathe polished rod keeps balance and operate as normal running polished rod suspension arrangement to polished rod when the running lathe.
(2) background technology
There is the conventional fixed carriage in lathe original production manufacturer on the body of lathe, use year number long afterwards, and former carriage can not have been kept normal running work, and the possibility of damaging machine body is arranged, and therefore must reequip.When machine tool running, polished rod is because exposed muchly outside also owing to factors such as gravity produce elastic bending deflection.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of when guaranteeing that lathe runs well in the production work process, solves the relatively-stationary a kind of polished rod suspension arrangement of polished rod.
The purpose of this utility model is achieved in that a kind of polished rod suspension arrangement, comprise a guide level mobile device, a coupling bar, one cover running bearing and polished rod, described guide level mobile device comprises carriage, carriage is grooved, the carriage notch is downward, the compound bakelite wear-resistant liner of carriage internal face, described coupling bar vertically is arranged at the carriage outside downwards, fixedly connected with the carriage outside in the coupling bar upper end, coupling bar lower end welding one cover running bearing, and described operating shaft is contracted and is drawn together axle sleeve and bearing, axle sleeve is sleeved on the polished rod, use key connecting between axle sleeve and the polished rod, bearing holder (housing, cover) is contained on the axle sleeve, and the bearing outer rim offers oil filler point.
The beneficial effects of the utility model are:
The utility model can support polished rod and not produce elastic bending deflection in the running by a suspension holdfast and a cover running bearing.When polished rod turned round, axle sleeve prolonged the service life of bearing because key connecting is arranged with polished rod run-in synchronism with polished rod greatly, and running steadily.
Adopt the utility model can make machine tool running normal, steadily.Make it bring into play its former design effect, normally put into production.The utility model is simple in structure, and is easy to operate.

(5) specific embodiment
Referring to Fig. 1～2, the utility model polished rod suspension arrangement comprises a guide level mobile device, coupling bar, a cover running bearing and a polished rod 5.Described guide level mobile device comprises carriage 10, and carriage 10 is grooved, and carriage 10 notches are downward, the compound bakelite wear-resistant liner 9 of carriage 10 internal faces, and bakelite wear-resistant liner 9 is fixedlyed connected with described carriage 10 usefulness bolts 7, and carriage 10 outer walls are provided with reinforcement 3.Described coupling bar 8 vertically is arranged at carriage 10 outsides downwards, fixedlys connected with bolt 7 with carriage 10 outsides in coupling bar 8 upper ends, arranged outside reinforcement 3 in the coupling bar 8.Coupling bar 8 lower ends welding one cover running bearing.Described running bearing is made up of axle sleeve 1, bearing 2 and key 4.Axle sleeve 1 is sleeved on the polished rod 5, and connects with key 4 between the polished rod 5, and bearing 2 is sleeved on the axle sleeve 1, and bearing 2 outer rims offer oilhole 6.
Operation principle: carriage at first is installed on the guide rail of machine body, so because carriage has the guide rail surface precision that can effectively protect lathe when the bakelite liner is actual to be used.Then with coupling bar and bearing 2, axle sleeve and lower bearing body with key connecting, be installed on the polished rod, bar and carriage again are fixedly connected thereafter.Earlier carriage is placed in the machine body lead rail axis on ideal position in the use, then mounted coupling bar and carriage is fixedly connected.Carriage is placed on the guide rail of machine body so dexterously, utilizes guide rail, carriage can be settled on the arbitrary length direction of guide rail easily, guaranteed installation accuracy as datum level.
