Abstract
The utility model relates to an axial positioning device for a horizontal rolling mill coupler. The axial positioning device comprises a roller 1, a cardan shaft coupler 4, a spline shaft sleeve 5 and a spline shaft 6, wherein a rolling mill head on the roller 1 is connected with the cardan shaft coupler 4; the axial positioning device is characterized in that two spline shaft sleeve U-shaped baffle rings 9 are symmetrically fixed on an outer wall of the spline shaft sleeve 5 of the cardan shaft coupler 4 at a 180-degree interval; two spline shaft U-shaped baffle rings 10 are also symmetrically fixed at the tail end of the spline shaft at a 180-degree interval; guiding holes are arranged on the spline shaft sleeve U-shaped baffle rings 9 and the spline shaft U-shaped baffle rings 10; two screw rods 8 respectively pass through the guiding holes on the spline shaft sleeve U-shaped baffle rings 9 and the spline shaft U-shaped baffle rings 10 and are fixed through bolts; and axes of the two screw rods and the axis of the spline shaft 6 are on the same plane. According to the requirements of quick roller exchanging and slot exchanging and accurate axial positioning of the cardan shaft, the two screw rods are arranged and can freely run when the spline shaft sleeve moves following a rolling mill frame. Each time the screw rods turn for one circle, the screw rods can advance and retreat for 12mm, so that quick advancing and retreating are realized; the screw rods are difficult to damage, so that the service life of the equipment is prolonged.
Description
Technical field
The utility model relates to a kind of universal drive shaft positioning adjustment device, particularly relates to the positioner of the thick middle horizontal mill Hooks coupling universal coupling of a kind of high-speed wire production line.
Background technology:
At present to roll the universal-joint spindle axial location of horizontal mill in thick be to realize axial location by the draw-in groove 2 on 1, the location snap ring 3 near one rotatable 90 °, milling train end and roll to high-speed wire production line, location snap ring 3 is connected by the snap ring set bolt 7 of two M20 and the universal drive shaft shaft coupling 4 of milling train end face, because the working environment of milling train is quite severe, often in water, water and the condition of high temperature, and in rolling process due to the shock and vibration of roll 1, cause the snap ring set bolt 7 of M20 often to fracture, snap ring 3 rust in location are dead, conventionally use and just lost efficacy for three months, cause universal drive shaft play accident, can not normally use, reorientating can only be by changes roll, changes during groove and with objects such as angle steel, universal drive shaft is withstood from rear end temporarily, and by interim measures such as iron wire binding, electric welding, owing to there is no fixing object of reference, locate inaccurate, cause universal-joint spindle heel and toe wear and roll off the production line in advance, consume a large amount of spare unit, spare part, only 2008 years, NeiMenggu BaoGang GangLian Co., Ltd's Bar Plant just changes 16 of universal-joint spindles, 18, axle sleeve, and need to drop into a large amount of human and material resources when changing roll, groove, extend roll changing time, directly have influence on production.
Summary of the invention:
The purpose of this utility model is to provide a kind of accurate positioning, does not reliably need a kind of horizontal mill shaft coupling axial direction positioning device of frequent replacing.
The purpose of this utility model is realized by following mode:
Horizontal mill shaft coupling axial direction positioning device, comprise roll 1, universal drive shaft shaft coupling 4, hub splines 5, splined shaft 6, milling train head on roll 1 is connected with universal drive shaft shaft coupling 4, it is characterized in that: on the lateral wall of the hub splines 5 of universal drive shaft shaft coupling 4, symmetrical 2 the U-shaped baffle rings 9 of hub splines of fixing are spent at interval 180, at 2 the U-shaped baffle rings 10 of splined shaft of fixing of spline the tip of the axis also interval 180 degree symmetries, the U-shaped baffle ring 9 of hub splines and the U-shaped baffle ring 10 of splined shaft are provided with pilot hole, 2 rhizoid thick sticks 8 are fixed through the pilot hole on the U-shaped baffle ring 9 of hub splines and the U-shaped baffle ring 10 of splined shaft and with bolt respectively, the axial line of the axial line of 2 rhizoid thick sticks and splined shaft 6 is in same plane.
Accompanying drawing explanation:
Fig. 1 does not transform previous horizontal mill shaft coupling axial direction positioning device;
Fig. 2 is the utility model horizontal mill shaft coupling axial direction positioning device;
Wherein: 1-roll, 2-draw-in groove, 3-location snap ring, 4-universal drive shaft, 5-universal drive shaft spline housing, 6-splined shaft, 7-snap ring set bolt, 8-leading screw, the U-shaped baffle ring of 9-hub splines, the U-shaped baffle ring of 10-splined shaft.
Beneficial effect:
According to roll change, change groove and need fast, the requirement accurately of universal drive shaft axial location, arranges a pair of leading screw, when spline housing moves with mill stand, operation freely.Leading screw often circles and can advance, retreats 12mm, realizes fast advance and retreat, and leading screw is not fragile yet in addition, puts life of equipment on record and extends.
The specific embodiment:
