Abstract

The utility model discloses a lifting structure for a leveler. The lifting structure comprises a worm wheel and worm device, a cross beam and an upper stander, wherein a case body of the worm wheel and worm device is connected with the cross beam to form a whole; a nut of the worm wheel and worm device is fixed on the cross and matched with outer splines formed on two screws; and terminals of the two screws are connected with each other by a ball-head type connection device. The ball-head type connection device comprises a semicircular pressing plate, a ball head and a concave ball gasket; the semicircular pressing plate buckles the ball head and is attached to the concave ball gasket; and the concave ball gasket is fixed on the upper stander and can slide around. The lifting structure transmits all leveling forces to the cross beam through the nut; during inclination adjustment, the screws are not required to generate flexibility to compensate the inclination; and the lifting structure can be used in all machine types.

Description

The level(l)ing machine lifting structure

Technical field:

The utility model relates to the coil of strip technical field of processing equipment, especially relates to a kind of level(l)ing machine lifting structure.

Background technology:

Level(l)ing machine is widely used in industries such as steel plate market, container, machine-building, household electrical appliance, automobile, boats and ships, stainless steel products, light industry; The level(l)ing machine lifting structure is an indispensable part in the level(l)ing machine, and present level(l)ing machine lifting structure generally adopts crank angle and lifting screw can not become the centre-to-centre spacing dual mode.See shown in Figure 1: adopt its worm gear screwdown gear 01 drive motor 02 of level(l)ing machine lifting structure of crank angle to move up and down with top working roll 03; Motor 02 drives bent axle trace rotation top working roll 03 again; This structure is comparatively complicated; The processing maintenance difficulties is big, cost is high, and motor 02 can not on-load rotation top working roll 03 in the course of work.See shown in Figure 2: lifting screw can not become the level(l)ing machine lifting structure of centre-to-centre spacing, and two motors 04 in its worm gear screwdown gear start drive top working roll 03 simultaneously and move up and down, and starts one of them just rotation adjustment of motor 04.2 distances of interface PP of this structure two screw rods in (rotation) adjustment of tilting are constant; 2 distances of PP become oblique line by horizontal line when adjustment is tilted; And 2 of the QQ of two screw rod upper ends are eternal constant, compensate variable quantity so need to rely on screw rod to produce deflection deformation.In this structure, worm gear case is fixed on the crossbeam, and the transmission of nut form is adopted in the worm gear axle center, and all corrective forces are passed to crossbeam through worm gear (nut), bearing, worm and gear casing, and can only be used on the minicomputer.

The utility model content:

The purpose of the utility model is a kind of new level(l)ing machine lifting structure that provides with regard to being the weak point that exists to prior art, it have simple in structure, process and assemble easily, good stability, maintenance and characteristics easy to maintenance.

For realizing above-mentioned purpose; The level(l)ing machine lifting structure of the utility model includes worm and gear device, crossbeam and upper spider; Wherein, the casing and the crossbeam of worm and gear device are connected as a single entity, and the nut in the worm and gear device is fixed on the crossbeam; And with take shape in two external splines on the screw rod and cooperate, the termination of two screw rods adopts bulb formula coupling arrangement to connect.

Preferred as technique scheme, described bulb formula coupling arrangement includes semicircle pressing plate, bulb and recessed ball pad, wherein, semicircle pressing plate fastens bulb and is pasting recessed ball pad, recessed ball pad be fixed on the upper spider can to around slide.

The beneficial effect of the utility model is: it can pass to crossbeam through nut with all corrective forces, when tilt adjustments, does not need screw rod to produce deflection deformation and compensates, and can be used for institute's organic type.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is done further explanation:

Fig. 1 is existing a kind of level(l)ing machine lifting structure sketch map;

Fig. 2 is existing another kind of level(l)ing machine lifting structure sketch map;

Fig. 3 is the structural representation of the utility model;

Fig. 4 is a bulb formula connecting device structure sketch map.

The specific embodiment:

See Fig. 3 and shown in Figure 4: the level(l)ing machine lifting structure of the utility model includes worm and gear device 10, crossbeam 20 and upper spider 30; Wherein, the casing of worm and gear device 10 and crossbeam 20 are connected as a single entity, and the nut in the worm and gear device 10 is fixed on the crossbeam 20; The rectangular spline transmission is adopted in nut (worm gear) axle center; External splines takes shape on two screw rods 11, with screw rod 11 be one, all corrective forces are passed to crossbeam 20 through nut; The termination of two screw rods 11 adopts bulb formula coupling arrangement to connect.Bulb formula coupling arrangement includes semicircle pressing plate 41, bulb 42 and recessed ball pad 43, and wherein, semicircle pressing plate 41 fastens bulb 42 and pasting recessed ball pad 43; Recessed ball pad 43 is fixed on can be to sliding all around on the upper spider 30; Thereby when tilting (rotation) adjustment, the interface O of screw rod 11,2 right-angle sides of B are apart from constant, and it is big that air line distance becomes; Do not need screw rod 11 to produce deflection deformation and compensate, can be used on institute's organic type.

The above is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model, and every equalization of doing according to the utility model changes with modifying and all belongs in the claim that the utility model contains.
