Abstract
A carbon brush type electric wheel with no-abrasion molybdenum filament comprises a bearing seat, a guiding wheel, an electric rib and a press cover. At least one through hole is axially excavated on the bearing seat; a carbon brush, a spring and a press cap of spring are mounted inside the through hole; the press cover is installed at the end of the through hole; the carbon brush contacts with the guiding wheel and the electric rib, and the press cap of spring contacts with the press cover. The utility model has the characters of no-abrasion molybdenum filament, long service life, low cost, great conductivity and steady run. And the utility model is mostly applicable for super CNC wirecutting machine.
Description
One, technical field
The utility model relates to electric spark CNC wire-cut machine, and particularly a kind of carbon brush formula does not have wearing and tearing molybdenum filament conductive casters.
Two, background technology
The cutting running of existing electric spark CNC wire-cut machine is performed meritorious deeds never to be obliterated, but it also exists following shortcoming or deficiency simultaneously: 1. conducting block causes shorten its service life to the serious wear of molybdenum filament, raises the cost; 2. conducting block itself is also ground groove by molybdenum filament, change new silk behind the fracture of wire after, molybdenum filament so produce wired, card thread, fracture of wire phenomenon, directly influences the normal operation of lathe in former wear grooves; 3. when molybdenum filament wearing and tearing, when fluffing, conduct electricity badly, cause job insecurity, influence cut quality and speed.
Three, summary of the invention
The purpose of this utility model provides a kind of improved carbon brush formula does not have wearing and tearing molybdenum filament conductive casters; adopt guide wheel carbon brush conductive mechanism; the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art; protect molybdenum filament not frayed effectively; improve its service life and electric conductivity, guarantee the normal operation of lathe.
Carbon brush formula described in the utility model does not have wearing and tearing molybdenum filament conductive casters, comprise bearing block, guide wheel and conducting strip and gland, at least one through hole axially is set on the described bearing block, be installed on carbon brush, spring and spring pressure cap in this through hole, the end is installed on gland, carbon brush contacts with guide wheel and conducting strip, and the spring pressure cap contacts with gland.
Wherein, be connected with electrified wire on the described gland.
The utility model has following advantage compared with prior art:
1, molybdenum filament does not have wearing and tearing, prolongs its service life, reduces cost;
2, conduct electricity very well, working stability, machine tool running is normal;
3, easy to use, the cutting efficiency height.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the utility model.
Five, the specific embodiment
Consult accompanying drawing, a kind of carbon brush formula does not have wearing and tearing molybdenum filament conductive casters, comprise bearing block, guide wheel and conducting strip and gland, at least one through hole (being expressed as 3 among the figure) axially is set on the bearing block 2, be installed on carbon brush 6, spring 7 and spring pressure cap 8 in this through hole, the end is installed on gland 9, and carbon brush contacts with guide wheel 4 and conducting strip 5, and spring pressure cap 8 contacts with gland 9.
Be connected with electrified wire 10 on the gland.Bearing 3 is installed in the bearing block 2, and the other end of bearing block 2 is equipped with nut 1.
Claims (2)
1. a carbon brush formula does not have wearing and tearing molybdenum filament conductive casters, comprise bearing block, guide wheel and conducting strip and gland, it is characterized in that axially being provided with on the described bearing block at least one through hole, be installed on carbon brush, spring and spring pressure cap in this through hole, the end is installed on gland, carbon brush contacts with guide wheel and conducting strip, and the spring pressure cap contacts with gland.
2. carbon brush formula according to claim 1 does not have wearing and tearing molybdenum filament conductive casters, it is characterized in that being connected with electrified wire on the described gland.
