Description
Technical field
The present invention relates to the molybdenum filament guide wheel used on a kind of cutting on line lathe, belong to machining technology field.
Background technology
Wire cutting machine tool has the advantages that high in machining efficiency, adaptability is good, has been widely used in the making of plate parts.
The guide wheel of wire cutting machine tool is the molybdenum filament important component that is positioned and be oriented to cutting workpiece, the sub-assembly of guide wheel it is main by
Godet roller, rotating shaft, bearing, bearing block composition, the quality of its performance directly influence the machining accuracy and product of linear cutting equipment
Quality.Existing guide pulley subassembly is primarily present following deficiency：
First, after guide pulley subassembly operation a period of time, axially rocking can occur because of the abrasion of bearing in godet roller, cause godet roller
On molybdenum filament shake, this can not only influence the machining accuracy of equipment, reduce the crudy of workpiece, but also can cause serious
Spark discharge, so as to increase the chance of fracture of wire.
2nd, flexibly operated to ensure godet roller, need to leave certain interval, therefore cutting workpiece between rotating shaft and bearing block
The saponification liquor of Shi Suoyong and the chip for producing easily enter bearing block inner chamber, the clearance of bearing is quickly increased, or even cause
Bearing damage, influences the normal operation of wire cutting machine tool.
Therefore, how to ensure guide pulley subassembly stable operation, improve equipment machining accuracy and reduce equipment failure rate, always
It is problem of the puzzlement about technical staff.
The content of the invention
A kind of drawback it is an object of the invention to be directed to prior art, there is provided guide wheel for wire cutting, is set with improving
Standby machining accuracy, it is ensured that the crudy of workpiece.
Problem of the present invention is realized with following technical proposals：
A kind of guide wheel for wire cutting, composition includes godet roller coaxially to each other, rotating shaft, two bearings and two bearings
Set, the godet roller is fixed on the middle part of rotating shaft, and two bearings are separately fixed at the two ends of rotating shaft, and two bearing holder (housing, cover)s are set with
It is fixed on wire cutting machine tool in two Bearing outers and by support, one end away from godet roller of each bearing holder (housing, cover) is equipped with
Adjustment gland, each adjustment gland is pressed in the outer of corresponding bearing by the inner hole of screw thread and corresponding bearing holder (housing, cover) and by disc spring
On circle.
The above-mentioned guide wheel for wire cutting, is equipped with spacer between each bearing and godet roller, the spacer is tightly placed in and turns
On axle, two annular boss coaxial with rotating shaft are equipped with the outer wall of each spacer.
The above-mentioned guide wheel for wire cutting, the bearing holder (housing, cover) near godet roller one end inner side be provided with corresponding spacer
The corresponding ring-type lip of annular boss.
The above-mentioned guide wheel for wire cutting, the race of the godet roller is V-groove.
The above-mentioned guide wheel for wire cutting, the bearing is zanjon bearing.
The present invention applies axial thrust using gland and disc spring is adjusted to the outer ring of bearing, the outer ring of bearing is produced axially
Displacement, to realize the real-Time Compensation of bearing clearance, effectively prevent the axial direction that godet roller produces by bearing wear and rocks, so that
Improve equipment machining accuracy, it is ensured that the crudy of workpiece.
The labyrinth structure that annular boss on spacer is formed can effectively prevent to cut saponification liquor and generation used during workpiece
Chip enter bearing holder (housing, cover) inner chamber, prevent saponification liquor and chip from damaging bearing, greatly reduce the fault rate of equipment, it is ensured that line
The normal operation of cutting off machine.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Marked in figure as follows：1st, godet roller, 2, spacer, 3, bearing, 4, adjustment gland, 5, disc spring, 6, bearing holder (housing, cover), 7, branch
Frame, 8, annular boss, 9, lip, 10, rotating shaft.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Referring to Fig. 1, the invention mainly comprises godet roller 1, spacer 2, bearing 3, adjustment gland 4, disc spring 5, bearing holder (housing, cover) 6, branch
Frame 7 and rotating shaft 10.
The race of godet roller 1 is designed as v-shaped structure, it is ensured that molybdenum filament does not shift；Race bottom design is circular arc
Shape, increases, it is ensured that the smooth sliding of molybdenum filament with molybdenum filament contact surface.
Godet roller 1 is fixedly connected with rotating shaft 10, is furnished with specially designed spacer 2, two annulars on spacer 2 in rotating shaft 10
Boss 8 forms labyrinth seal structure, by the different annular boss 8 of two diameters, the saponification that will can enter in bearing holder (housing, cover) 6
Liquid throws away, so as to effectively protect the safety of bearing.
The both sides of godet roller 1 are equipped with bearing 3, it is ensured that the stability that godet roller 1 is rotated.When carrying out type selecting to bearing 3, should
Selection axial offset is small and is easy to the zanjon bearing of adjustment.
