Technical field
The utility model relates to a kind of self-adjustable turning rolls, especially relates to a kind of self-adjustable turning rolls that consists of active roller group and return idler group.
Background technology
At present, the self-adjustable turning rolls mainly comprises the active roller frame, the return idler frame, and drive unit, be arranged at two groups of active roller groups on the active roller frame and be arranged at two groups of return idler groups on the return idler frame; The active roller group consists of the two groups of active rollers in up and down.The running of active roller, by the running of reductor Synchronous Transmission, adopts speed setting controller to realize infinitely variable speeds by buncher.Mechanical transmission noise is low, and workpiece turning spur speed is 5-70m/h.It can regulate the pivot angle of wheels automatically according to diameter of work size, and can automatic aligning, when self-adjustable turning rolls and manipulator, when the source of welding current is supporting, can realize inside and outside longitudinal joint and the inner and outer ring seam welding of workpiece.
The roller of existing self-adjustable turning rolls and the contact area of workpiece are limited, frictional force both is too little, there are eccentric workpiece or the rough workpiece of surface transition for center of gravity, are prone to the phenomenon of skidding or beating in rotation process, processing second-rate.Simultaneously, the limited roller unit are that also makes of the contact area of roller and workpiece is stressed larger, the roller of active roller group particularly, and it bears the driving force that drives workpiece, and its wearing and tearing are very fast.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of self-adjustable turning rolls that workpiece rotating is steady, contact is good that allows is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of self-adjustable turning rolls, comprise the active roller frame, the return idler frame, drive unit, be arranged at two groups of active roller groups of active roller frame both sides and be arranged at two groups of return idler groups of return idler frame both sides; Described active roller group consists of the two groups of active rollers in up and down, and described return idler group consists of the two groups of return idlers in up and down, and described active roller consists of side by side three the first rollers, and each first roller surface is provided with the first skid resistant course.
Preferably, described the first skid resistant course is made by rubber or plastic cement.
Preferably, described drive unit is two groups, drives respectively two groups of active roller groups.
Preferably, described drive unit comprises buncher and cycloidal planetary gear speed reducer, and described cycloidal planetary gear speed reducer drives active roller by gear train.
Preferably, described return idler consists of side by side three the second rollers, and each second roller surface is provided with the second skid resistant course.
Preferably, the second skid resistant course is made by rubber or plastic cement.
Compared with prior art, the utlity model has following advantage:
(1) the utility model, by adopting the active roller supporting drive workpiece that is comprised of side by side three the first rollers, effectively increases the contact area of workpiece and active roller group the first roller, and the pressure of the first roller unit are effectively reduces.Therefore, extended the service life of active roller.Simultaneously, on the surface of the first roller, the first skid resistant course is set, can effectively guarantees the first roller good contact of workpiece and active roller group, workpiece substantially not there will be and skids and affect the precision that adds man-hour.And when the surface of the work transition was unsmooth or bias is arranged, skid resistant course can adapt to the surface of workpiece by the distortion of self, prevented that workpiece from beating, and made the workpiece rotating operation more steady.
(2) the utility model is rational in infrastructure, and is easy to use.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is the cutaway view of A-A in Fig. 1;
Fig. 3 is the enlarged drawing of B part in Fig. 2;
Fig. 4 is the enlarged drawing of C part in Fig. 2.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment that obtains, and all belong to the scope of the utility model protection.
Fig. 1 to Fig. 4 is a specific embodiment of the utility model self-adjustable turning rolls, comprise active roller frame 1, return idler frame 11, drive unit 2, be arranged at two groups of active roller groups 3 of active roller frame 1 both sides and be arranged at two groups of return idler groups 4 of return idler frame 11 both sides; Drive unit 2 has two groups, drives respectively two groups of active roller groups 3, and it comprises buncher 21 and cycloidal planetary gear speed reducer 22, and cycloidal planetary gear speed reducer 22 drives active roller group 3 by gear train; Two groups of active roller groups 3 are arranged on the both sides formation cooperation of active roller frame 1, and two groups of return idlers 4 are arranged on the both sides formation cooperation of return idler frame 11.Active roller group 3 consists of the two groups of active rollers 31 in up and down, and active roller 31 consists of side by side three the first rollers 32, and each first roller 32 surface is provided with the first skid resistant course 33, the first skid resistant courses 33 and can adopts rubber or plastic cement to make.By adopting the active roller 31 supporting drive workpiece 5 that formed side by side by three the first rollers 32, effectively increase the contact area of workpiece 5 and active roller group 3 active rollers 31, the pressure of active roller 31 unit ares effectively reduces.Therefore, extended the service life of active roller 31.Simultaneously, the first skid resistant course 33 is set on the surface of the first roller 32, can effectively guarantees the first roller 32 good contacts of workpiece 5 and active roller group 3, workpiece 5 substantially not there will be and skids and affect the precision that adds man-hour.And when workpiece 5 surface transition were unsmooth or bias is arranged, the first skid resistant course 33 can adapt to the surface of workpiece 5 by the distortion of self, prevented that workpiece 5 from beating, and made workpiece 5 rotating operations more steady.
