Background
A high-speed finishing mill for high-speed wire is composed of a high-speed rolling mill, two rolling rollers on said high-speed rolling mill, and a gap between two axial locating bearings on said two rolling rollers for determining if said two rolling rollers are in reasonable range.
At present, after the two roll shaft axial clearances are measured by directly tilting the roll shafts by using a crowbar, whether the two roll shaft axial clearances are out of tolerance is determined through experience senses of assembly workers, measured data are inaccurate, and because the force of each measuring person is different, if the prying force is too large, the axial positioning bearing can be damaged, the measuring mode is very unscientific, the measured data are not standard, and the equipment hidden danger in the online use process can be caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an altitude finishing mill axial clearance measures appurtenance can replace the manual work to utilize the crowbar to stick up the roll axle, for the axial clearance measurement of finishing mill provides reliable data, solves the problem that exists among the background art.
The technical scheme of the utility model is that:
the utility model provides an altitude finishing mill axial clearance measures appurtenance, contains angle steel, fixing bolt, plain cushion, square lever, roll axle, moment spanner and percentage table, and one side of two angle steels is fixed on two roll axles of finishing mill through fixing bolt and plain cushion respectively, and the another side of two angle steels links together through square lever, square lever is arranged perpendicularly with the central line of two roll axles of finishing mill, and the one end at square lever is fixed to the moment spanner, and the percentage table is fixed on the shaft shoulder of the roll axle that is close to moment spanner one end.
One side of the angle steel is provided with a round hole matched with the fixing bolt, and the other side of the angle steel is provided with a square hole matched with the square lever.
The square lever penetrates through a square hole in the angle steel, and a limit stop matched with the square hole is arranged on the square lever.
The end of the square lever is fixed with a nut, and the torque wrench is in threaded connection with the nut.
Adopt the utility model discloses, when measuring altitude finishing mill axial clearance, at first with the percentage table reading to digit 0, set for the moment spanner to 90NM moment back again, upwards lift up the moment spanner and drive the roller axle together rebound, its moving range is measured out concrete data by fixing the percentage table on the shaft shoulder, and this data is exactly the axial clearance of roller axle.
The utility model has the advantages that: can replace the manual work to utilize the jimmy stick perk to roll the axle to measure axial clearance through the percentage table, its measurement accuracy is higher, can not cause the damage to the bearing of roll axle because the too big power that utilizes the jimmy stick perk roll in addition, not only for finishing mill provides higher assembly precision, but also prevented the unexpected damage of bearing, thereby improved the life of finishing mill, reduced finishing mill spare part cost.

Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to the attached drawings 1-6, an auxiliary tool for measuring axial clearance of a high-speed wire finishing mill comprises angle steel 2, a fixing bolt 4, a flat polishing pad 5, a square lever 6, a rolling roll shaft 7, a torque wrench 8 and a dial indicator 9, wherein one side of each of the two angle steel 2 is fixed on the two rolling roll shafts 7 of the finishing mill through the fixing bolt 4 and the flat polishing pad 5 respectively, the other sides of the two angle steel 2 are connected together through the square lever 6, the square lever 6 is perpendicularly arranged with the central lines of the two rolling roll shafts 7 of the finishing mill, the torque wrench 8 is fixed at one end of the square lever 6, and the dial indicator 9 is fixed on a shaft shoulder of the rolling roll shaft 7 close to one end of the torque wrench.
In this embodiment, referring to fig. 1-4, one side of the angle iron 2 is provided with a round hole 3 matched with a fixing bolt 4, and the other side of the angle iron 2 is provided with a square hole 1 matched with a square lever 6. The internal diameter of the square hole 1 of the angle steel 2 is larger than the square lever 6, the difference value of the internal diameter is within 0.5mm, so that the square lever 6 is controlled to move in the square hole 1, the round hole 3 of the angle steel 2 is a mounting hole for the fixing screw 4, and the flat light pad 5 is used for preventing the fixing screw 4 from loosening under the fixing screw 4. The dial indicator 9 is placed on the shaft shoulder of the roll shaft 7 and used for collecting the displacement data of the roll shaft.
Referring to fig. 5 and 6, a limit stop 10 is arranged on the square lever 6, and the position of the square lever 6 on the angle steel 2 is controlled through the limit stop 10. One end of the square lever 6 is welded with two M16 nuts 11 for mounting the torque wrench 6.
When the axial clearance of the high-speed wire finishing mill is measured, firstly, the reading of the dial indicator 9 is aligned to the number 0, then, after the torque wrench 8 is set to the torque of 90NM, the torque wrench 8 is lifted upwards to drive the roll shaft 7 to move upwards together, the moving range of the torque wrench is measured by the dial indicator 9 fixed on the shaft shoulder, the data is the axial clearance of the roll shaft 7, and the dial indicator 9 is selected from 0-10 lever dial indicators according to the requirement of the measuring range.
