Description
Technical Field
The utility model relates to a large aperture steel pipe machining mechanism subassembly, the large aperture steel pipe slotting machine of specifically saying so is with chuck of rectifying.
Background
In order to ensure the sealing performance of the butted steel pipes, sealing ring grooves for placing sealing rings are processed at the end parts of the large-aperture steel pipes. When the large-aperture steel pipe is grooved, the chuck is required to position the steel pipe.
At present, chucks for fixing steel pipes in the industry are chucks of a steel pipe grinding machine, and the chucks are simple steel cones. During the use, adopt two chucks, the little section of chuck diameter is towards another chuck, has placed two chucks with the steel pipe between, and the position of adjustment chuck for the steel pipe presss from both sides tightly can between the conical surface of two chucks. Due to manufacturing and assembly errors, there is some misalignment of the steel tube with the collet. When the chuck is used for grooving and fixing a large-diameter steel pipe, due to the concentricity, the opened annular groove is uneven, and the sealing effect is greatly influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a large aperture steel pipe slotting machine is with chuck of rectifying, the sealed effect of the heavy-calibre steel pipe of adopting this chuck processing is better.
In order to solve the problems, the following technical scheme is provided:
the utility model discloses a large aperture steel pipe slotting machine is with chuck of rectifying's characteristics are including the supporting disk, have central circle hole in the supporting disk quotation, have the loop in the central circle hole, and the external diameter of loop is less than the diameter that central circle was bored, and the oral area that the one end of loop was bored from central circle stretches out outside. The supporting disk quotation in the center round hole outside has the guide way along the circumference equipartition of supporting disk, and the one end in guide way all is located the lateral wall in center round hole for the guide way is linked together with center round hole. The guide groove is internally provided with a screw rod which is longitudinally arranged along the guide groove, one end of the screw rod penetrates through the end, far away from the central circular pit, of the guide groove and extends out of the supporting disk, and the screw rod and the supporting disk are in circumferential rotation and axial fixation fit. The guide groove is internally provided with a puller block, one side of the puller block is positioned in the central circular pit, the puller block is provided with threaded holes longitudinally arranged along the guide groove, the screw rods are positioned in the corresponding threaded holes so as to rotate the screw rods, and the puller block slides in the guide groove.
Wherein, the section of the loop outside the central circular pit is concentrically fixed with a support ring.
By adopting the scheme, the method has the following advantages:
because the utility model discloses a large aperture steel pipe slotting machine is with having the loop in the center round hole of chuck of rectifying, the external diameter of loop is less than the diameter that center round hole, it has the guide way to follow the circumference equipartition of supporting disk on the supporting disk quotation in the center round hole outside, the one end of guide way all is located the lateral wall that center round hole, there is the screw rod along its longitudinal arrangement in the guide way, the guide way one end that keeps away from center round hole is passed to the one end of screw rod stretches out outside the supporting disk, there is the puller block in the guide way, one side of puller block is located the center pit, there is the screw hole along guide way longitudinal arrangement on the puller block, the screw rod is located corresponding screw hole, so that rotate the screw rod, the puller block slides in the guide way. The position of the loop can be adjusted by the deviation correcting chuck through the jacking block. When the large-aperture steel pipe active rotating shaft is used, the large-aperture steel pipe is rotated after the large-aperture steel pipe is installed, the large-aperture steel pipe is measured through the dial indicator, the position of the loop is adjusted according to measurement data, and therefore the concentricity of the large-aperture steel pipe and the active rotating shaft can be guaranteed, the machined annular groove is smooth, and the sealing effect is good.
Drawings
Fig. 1 is the structure schematic diagram of the deviation rectifying chuck for the large-aperture steel pipe slotting machine of the utility model.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses a large aperture steel pipe slotting machine is with chuck of rectifying includes supporting disk 4, has central round hole 5 in the 4 quotations of supporting disk, has loop 7 in central round hole 5, and the external diameter of loop 7 is less than the diameter of central round hole 5, and the one end of loop 7 stretches out outside from the oral area of central round hole 5. The supporting disk 4 quotations in the 5 outsides in center circle hole have the guide way 2 along the circumference equipartition of supporting disk 4, and the one end of guide way 2 all is located the lateral wall in center circle hole 5 for guide way 2 is linked together with center circle hole 5. The guide groove 2 is internally provided with a screw rod 3 which is longitudinally arranged along the guide groove, one end of the screw rod 3 penetrates through the end, far away from the central circular pit 5, of the guide groove 2 and extends out of the supporting disk 4, and the screw rod 3 and the supporting disk 4 are in circumferential rotation and axial fixed fit. The improved structure of the screw rod is characterized in that a jacking block 1 is arranged in the guide groove 2, one side of the jacking block 1 is positioned in the central circular pit 5, threaded holes longitudinally arranged along the guide groove 2 are formed in the jacking block 1, the screw rod 3 is positioned in the corresponding threaded hole so as to rotate the screw rod 3, and the jacking block 1 slides in the guide groove 2. A supporting ring 6 is concentrically fixed on the section of the loop 7 which is positioned outside the central circular pit 5.
The position of the loop 7 can be adjusted by the deviation correcting chuck through the jacking block 1. When the large-aperture steel pipe active rotating shaft is used, after the large-aperture steel pipe is installed, the large-aperture steel pipe is rotated, the large-aperture steel pipe is measured through the dial indicator, the position of the loop 7 is adjusted according to measurement data, and therefore the concentricity of the large-aperture steel pipe and the active rotating shaft can be guaranteed, the machined annular groove is smooth, and the sealing effect is good.
