Abstract
The utility model discloses an idler wheel of a turning roller. The idler wheel of the turning roller comprises a wheel body and a shaft hole. The shaft hole is arranged along the axial center of the wheel body. A cavity is formed in the wheel body. Compared with the prior art, the cavity is formed in the idler wheel, the overall toughness of the idler wheel is enhanced under the condition that requirements for strength and stiffness are met, the deformation of the idler wheel can be adjusted according to changes in acting force of a heavy-load workpiece, and therefore the integrity of the workpiece is protected, and the welding quality of the workpiece is improved.
Description
Technical field
The utility model belongs to auxiliary field of welding devices, relates to a kind of turning rolls roller specifically.
Background technology
Turning rolls is a kind of auxiliary welding equipment, is mainly used in auxiliary welding tubular heavy load workpiece.Specifically be that tubular heavy load workpiece is placed on the roller of turning rolls, by driving rolls workpiece rotated, satisfy the workpiece process requirements.The roller of turning rolls is its important building block, realizes supporting and turning of work piece, and is therefore also comparatively strict for roller machinery performance demands.
Existing roller mostly is the bigger solid roller of hardness, though can satisfy the support degree to workpiece, but the relatively poor workpiece of considering of the toughness of solid roller mostly is the tubular heavy load, and the less roller of workpiece and toughness contacts and causes the workpiece surface damage easily even bulk deformation takes place.So how to improve the overall flexibility of roller, realizing supporting and rotating cylindrical work pieces preferably becomes the urgent difficult problem that need solve.
The utility model content
The technical problem that the utility model solves provides a kind of toughness and intensity good comprehensive properties turning rolls roller, improves the welding quality of workpiece.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is a kind of turning rolls roller, comprises wheel body and axis hole, and axis hole arranges that along the axial centre of wheel body described wheel body inside is provided with cavity.
Compare with prior art, in roller inside cavity is set in this programme, under the condition that satisfies the strength and stiffness requirement; improved the overall flexibility of roller; can adjust self deformation according to the variation of force of heavy load workpiece, effectively protect the complete of workpiece, improve the workpiece welding quality.
Based on such scheme, the utility model also further proposes following improvement:
Described wheel body comprises cylinder and a pair of side dish, and the side dish is welded in and forms described cavity on the cylinder, and axis hole is arranged on the side dish.
The axial medial surface of axis hole is provided with keyway.
Side dish inboard is provided with the reinforcement feature that cooperates with keyway around the axis hole periphery.
Described reinforcement feature is ring set, and ring set is provided with auxiliary keyway, and auxiliary keyway and keyway are corresponding to be arranged, ring set is whole and axis hole is supporting.
Between described ring set and the side dish by being welded to connect.
Above improvement project, the pair roller structure further limits, and has optimized the overall performance of roller.
Description of drawings
Fig. 1 is that roller is installed in the structural representation on the turning rolls.
Fig. 2 is the sectional drawing of roller described in the utility model.
Fig. 3 be roller described in the utility model along A-A among Fig. 2 to sectional drawing.
Among the figure, 1. cylinder; 2. side dish; 3. keyway; 4. ring set; 5. axis hole; 6. roller.
The specific embodiment
As shown in Figure 1, the utility model relates generally to the architecture advances of the roller 6 on the turning rolls.Thinking is: in order to improve ductile deformation's ability of the overall performance of roller, especially roller, the utility model under the condition that keeps certain degree of hardness and rigidity, improves roller toughness by the mode of cavity is set in roller.Below in conjunction with embodiment and accompanying drawing the utility model is elaborated.
Embodiment:
Shown in Fig. 2,3, in the present embodiment, roller 6 is made up of cylinder 1 and side dish 2, and cylinder 1 can pass through casting, smooth surface, and side dish 2 is installed two, and they are welded on two ports and the cylinder 6 common cavitys that form of cylinder 6 respectively.Side dish 2 axis hole 5 that loaded, axis hole 5 be used for and turning rolls on rotating shaft cooperate.In order to satisfy rotating shaft and axis hole 5 is linked, in axis hole 5 inboards keyway 3 is set, cooperate by retainingf key and keyway 3, roller 6 is fixed in the rotating shaft.
Because the inner cavitys that form of roller 6, make the contraction in length of keyway 3, the steadiness of keyway 3 and security reduce significantly like this.Based on this, present embodiment is done further improvement to such scheme, in the welding of the inboard of side dish 2 ring set 4 is set, this ring set 4 is reinforcement feature, ring set 4 and axis hole 5 do not influence rotating shaft simultaneously and are connected with axis hole 5, preferably the equal diameters of the diameter of the endoporus of ring set 4 and axis hole 5.Also be provided with auxiliary keyway on the ring set 4, this auxiliary keyway and keyway 3 correspondences satisfy a retainingf key and can run through keyway 3 and auxiliary keyway simultaneously.This reinforcement feature also can be the miscellaneous part of similar ring set 4; Or other shaped members, as long as can play reinforcement effect.
During work, cylindrical work pieces is positioned on a pair of turning rolls, workpiece applies pressure to the surface of roller 6, because roller 6 be hollow structure, and when the surface is subjected to the heavy load extruding, the generation micro-deformation, thus play the effect of buffering.
