Abstract
The utility model discloses a guide sleeve applied to a longer mechanical movement position, and particularly relates to a combined type guide sleeve applied to a position with higher requirement for guide precision. The combined type guide sleeve is characterized by comprising a seamless steel tube and copper end sleeves, and the copper end sleeves are arranged at two ends of the seamless steel tube in close fit. The combined type guide sleeve has the advantages of high guide precision, long service life and low production cost.
Description
Technical field
The utility model relates to a kind of combined fairlead, is used for the guiding at the longer position of mechanical movement, especially is applied to require the higher position of guiding accuracy.
Background technology
The existing fairlead that is used for the longer position of mechanical movement is generally the copper sheathing that one section split is respectively adorned at two ends, because two sections split guiding copper sheathing machining accuracies can not be in full accord, so just cause the gap of the copper sheathing at two ends and the axis of guide inconsistent, its shortcoming is that the guide pin bushing circumference wearing and tearing of guiding position are inhomogeneous, guiding accuracy is low, and service life is short.Use long guiding copper sheathing cost higher simultaneously.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and a kind of guiding accuracy height, long service life, combined fairlead that production cost is low are provided.
The technical scheme in the invention for solving the above technical problem is: this combined fairlead, its characteristics are: comprise seamless steel pipe and copper end cover, copper end is locked to join and is arranged on the seamless steel pipe two ends.
The utility model compared with prior art has the following advantages: 1, rigidity is better, and is not yielding, improved service life.2, the copper sheathing production cost than full copper has reduced 60%-80% (cost of the long more big more reduction of fairlead is many more).3, two ends endoporus φ A axiality height, the L size is big more, and guiding accuracy is just high more.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model mounting structure schematic diagram.
The specific embodiment
Referring to Fig. 1, the utility model comprises seamless steel pipe 2 and copper end cover 1,3, combine with better seamless steel pipe 2 of rigidity and wear-resisting copper end cover 1,3, promptly copper end overlaps 1,3 on seamless steel pipe 2 two ends hot jackets, again this part is processed into the size of designed requirement as an one-piece parts, for long guide pin bushing, the advantage of this kind structure is particularly evident.Because the centre is a steel part, thus be difficult for producing flexural deformation with respect to full copper spare in the process, and the axiality of the two ends endoporus that bores is also higher.Because integral rigidity is better, in assembling process, also be difficult for knocking diastrophic situation, in use because heating is not yielding yet, the raising of rigidity in a word makes guiding accuracy that reliable assurance all arranged.The wearing and tearing of the circumference of this part circumference and the axis of guide are just compared evenly like this, and the circumference wearing and tearing in use of this part are just slower like this, and the monolateral defective of having avoided wearing and tearing, so also can extend greatly service life.Because fairlead is longer, two ends endoporus axiality height, guiding accuracy is also higher.Because use steel part to replace middle copper spare, cost also can reduce greatly.
Referring to Fig. 2, the combined fairlead 4 that dipped in lubricating oil is driven in the hole of moving component 6 gently during use with copper rod, and touch lubricating oil at the two ends of combined fairlead 4 endoporus, again the axis of guide 7 is packed in the combined fairlead 4, then the gland 5 that installs dust ring 8 is screwed on moving component 6, the fit clearance of the two ends of combined like this fairlead 4 and the axis of guide 7 is more even, wearing and tearing between the two also relatively evenly so, improved the service life of guide pin bushing greatly, simultaneously because the axiality at combined guide pin bushing 4 two ends is higher, the skew of moving component 6 on the axis of guide 7 is also very little so, and guiding accuracy is very high (will choose the fit clearance of the axis of guide 7 and combined guide pin bushing 4 endoporus) just during design.
