Description
Technical field:
The utility model relates to field of metallurgical machine, relates in particular to a kind of spindle mounting structure of cold centring machine.
Background technology:
Seamless steel pipe be a kind ofly have hollow section, periphery does not have jointed circle, and is square, the rectangle steel.Seamless steel pipe is to make hollow billet with steel ingot or the solid pipe hole that wears long, and then makes through hot rolling, cold rolling or cold group.Seamless steel pipe has hollow section, a large amount of pipelines as carrying fluid, steel pipe is compared with solid steel such as round steel, when the bending resistance torsional strength is identical, weight is lighter, be a kind of Economic Section steel, be widely used in manufacturing structure spare and machine components, such as steel scaffold of using in oil drill rocker, truck drive shaft, bicycle rack and the construction etc.Main technique has when the processing seamless steel pipe, circular pipe blank → heating → perforation → roller trio skew rolling, tandem rolling or extruding → take off pipe → sizing → cooling → aligning → flaw detection → mark → warehouse-in, seamless steel pipe is to make hollow billet with steel ingot or the solid pipe hole that wears long, and then makes through hot rolling, cold rolling or cold group.Therefore imagination provides a kind of spindle mounting structure of cold centring machine to improve the qualification rate of seamless steel pipe.
The utility model content:
The purpose of this utility model just provides a kind of spindle mounting structure of cold centring machine, to solve the deficiency of existing issue.
The technical solution adopted in the utility model is:
A kind of spindle mounting structure of cold centring machine, comprise frame, the frame upper end is slidingly fitted with movable platform, be installed with holder on the movable platform, the holder upper end is provided with cavity, and main shaft is installed in the cavity, spindle jacket is equipped with bearing, front-end of spindle stretches out outside the holder and steel tube fixing device is installed, and the leading section of holder is equipped with gland by front bolt, is installed with J type outside framework oil seal on the gland; The holder rear end is equipped with rear end cap by rear bolt, is installed with balancing point line wheel reductor on the rear end cap, and rear-end of spindle is connected to the output shaft of balancing point line wheel reductor, and the main shaft end is set with standby cap outward; Frame movable upper end platform side also is equipped with cylinder, and cylinder is connected to holder by connecting rod.
Described frame upper end has slideway, and the movable platform bottom is provided with projection and snaps in the slideway, and can slide along slideway.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is simple in structure, and is reasonable in design, easy to use, and security performance is high, can improve the qualification rate of seamless steel pipe, the production efficiency that has improved.
