Abstract
The invention relates to an adjusting mechanism of a straightening machine centering roller. The adjusting mechanism is characterized in that a sliding sleeve, a sliding sleeve seat lead screw, a nut, a bearing pedestal and a hand wheel are included, the sliding sleeve is movably arranged in the sliding sleeve seat, the sliding sleeve can be driven by a sliding driving mechanism to axially slide, a sliding guide mechanism is arranged between the sliding sleeve and the sliding sleeve seat, and the front end of the sliding sleeve is used for allowing the centering roller to be mounted. The lead screw is supported and arranged in the bearing pedestal through a bearing assembly, the bearing pedestal is fixedly arranged on a rack behind the sliding sleeve seat, one side of the bearing assembly is limited by a limiting table arranged on the lead screw, and the other side of the bearing assembly is locked and fixed through a locking nut assembly. The front end of the lead screw stretches into the sliding sleeve, and a nut assembled on the lead screw is fixed to the sliding sleeve. The hand wheel is fixedly arranged at the rear end of the lead screw. The adjusting mechanism is simple in structure, the position of the centering roller can be adjusted precisely, then H-shaped steel is precisely straightened, operation is convenient, and the product precision, machining efficiency and automation degree of the H-shaped steel are greatly improved.
Description
Technical field
The present invention relates to the governor motion of arbor press righting roller, belong to steel construction processing and manufacturing technical field.
Background technology
Along with the fast development of China's steel construction industry, the H profile steel for steel-structure factory building develops to meticulous type and heavy duty detergent day by day, and the group how improving H profile steel founds precision, working (machining) efficiency and automaticity, has become the difficult problem that steel construction industry must overcome.
H profile steel is by two blocks of wing plates and assembled group of one block of web is vertical forms, and the relative position relation of web and wing plate directly has influence on the qualification rate of H profile steel finished product.Existing general group to found machine be all by carrying out the setting of artificial position to the assembly welding of H profile steel needed in advance, and then carry out H-shaped steel assembly welding, adopt the position that the H profile steel of processing in this way is difficult to locate exactly each plate, always there will be some deviations, this just needs to use follow-up rectification step.But current arbor press by structural design too complicated, be not suitable for production requirement, and structure too simple exist correct the low problem of precision.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of governor motion of arbor press righting roller is provided, its structure is simple, can the position of fine adjustment righting roller, and then accurate straightening H shaped steel, and easy to operate, substantially increase the Product Precision of H profile steel, working (machining) efficiency and automaticity.
According to technical scheme provided by the invention: the governor motion of arbor press righting roller, it is characterized in that: comprise sliding sleeve, sleeve base screw mandrel, screw, bearing block and handwheel, described sliding sleeve is movably set in sleeve base, sliding sleeve can slide axially under sliding drive mechanism drives, be provided with sliding guide mechanism between sliding sleeve and sleeve base, sliding sleeve front end is for installing righting roller; Described screw mandrel is arranged in bearing block by bearing assembly supporting, and bearing block is fixedly mounted in the frame at sleeve base rear, and the limiting stand that bearing assembly side is provided with by screw mandrel is spacing, and bearing assembly opposite side is locked by lock nut assembly; Described screw mandrel front end is stretched in sliding sleeve, and the screw that screw mandrel is furnished with is fixed on sliding sleeve; Described screw mandrel rear end fixed installation handwheel.
As a further improvement on the present invention, described sliding sleeve is provided with guide groove along its length, and described sleeve base is provided with key, and this key is fitted in the guide groove on sliding sleeve, forms gliding movement targeting structure thus.
As a further improvement on the present invention, described lock nut assembly comprises two round nuts.
As a further improvement on the present invention, described bearing assembly comprises two thrust ball bearings, and two thrust ball bearings are contained in the bearing mounting hole on bearing block two sides respectively, are separated between two thrust ball bearings by an interior step.
compared with prior art, tool has the following advantages in the present invention:this present invention structure is simple, can the position of fine adjustment righting roller, and then accurate straightening H shaped steel, and easy to operate, substantially increases the Product Precision of H profile steel, working (machining) efficiency and automaticity.
Accompanying drawing explanation
Fig. 1 is the structural front view of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure, the governor motion of the arbor press righting roller in embodiment is primarily of compositions such as sliding sleeve 1, sleeve base 2, screw mandrel 3, screw 4, thrust ball bearing 5, bearing block 6, round nut 7, handwheel 8 and keys 10.
As shown in Figure 1, described sleeve base 2 is arranged in frame 9, and sliding sleeve 1 is movably set in sleeve base 2, and sliding sleeve 1 can slide axially under sliding drive mechanism drives, and is provided with sliding guide mechanism sliding sleeve 1 front end for installing righting roller 2 between sliding sleeve 1 and sleeve base 2; Described screw mandrel 3 is arranged in bearing block 6 by bearing assembly supporting, and bearing block 6 is fixedly mounted in the frame 9 at sleeve base 2 rear, and the limiting stand that bearing assembly side is provided with by screw mandrel 3 is spacing, and bearing assembly opposite side is locked by lock nut assembly; Described screw mandrel 3 front end is stretched in sliding sleeve 1, and the screw 4 that screw mandrel 3 is furnished with is fixed on sliding sleeve 1; Described screw mandrel 3 rear end fixed installation handwheel 8.
As shown in Figure 1, in the embodiment of the present invention, described slip sliding sleeve 1 is provided with guide groove 1a along its length, and described sleeve base 2 is provided with key 10, and this key 10 is fitted in the guide groove 1a on sliding sleeve 1, forms gliding movement targeting structure thus.
As shown in Figure 1, in the embodiment of the present invention, described lock nut assembly forms primarily of two round nuts 7, and two round nuts 7 form anti-loose structure.Described bearing assembly forms primarily of two thrust ball bearings 5, and two thrust ball bearings 5 are contained in the bearing mounting hole on bearing block 6 two sides respectively, are separated between two thrust ball bearings 5 by an interior step.
During embody rule, when needs straightening H shaped steel, turn handwheel 8, handwheel 8 drives screw mandrel 3 to rotate, be arranged on the screw 4 on screw mandrel 3 and the sliding sleeve 1 that is fixedly connected with screw 4 is just movable, thus drive righting roller to move, righting pair of rollers H profile steel need the position adjusted apply active force, the relative position relation of accurate adjustment web and wing plate.
