Abstract
Disclosed is a guide wheel. The guide wheel is fixed at one end of a guide wheel shaft, and an external screw thread is arranged at the other end of the guide wheel shaft. A guide wheel seat is formed into a cylinder. A guide wheel shaft hole is formed in one end of the guide wheel seat, and a bearing is mounted in the guide wheel seat when mounting the guide wheel shaft hole. The guide wheel is mounted in the bearing which is placed inside the guide wheel seat which is provided with the bearing in advance through the guide wheel shaft. Then a locknut is screwed into the end of the guide wheel shaft. At last, a copper cover is screwed into the guide wheel seat through a screwdriver. Therefore, molybdenum wires of the guide wheel can be changed conveniently, manufacturing cost is saved and structure is simple.
Description
Technical field
The utility model relates to a kind of accessory of wire cutting machine tool, specifically a kind of guide wheel of wire cutting machine tool molybdenum filament.
Background technology
Existing guide wheel mostly arranges wheel stand and bearing at the two ends of guide wheel, but when changing molybdenum filament, because guide wheel is positioned in the middle of two wheel stands, molybdenum filament must pass from the centre and could change, trouble seems, and it is also many, so both uneconomical to make the raw material that guide wheel consumes, and it is also many to wear the used time of molybdenum filament.
Summary of the invention
In order to remedy the above-mentioned deficiency of guide wheel, the utility model provides a kind of guide wheel, this guide wheel is only established a side guide wheel seat, and guide wheel is fixed on an end of guide wheel shaft, in the guide wheel outside without any a resistance shelves part, therefore, when changing molybdenum filament, do not spend and wear, as long as directly once just become last time at guide wheel, not only convenient, and also saved raw material when making guide wheel.
The utility model solves the technical measures that its technical problem takes, guide wheel is by guide wheel, guide wheel shaft, wheel stand, locking nut and copper lid form, guide wheel is fixed on an end of guide wheel shaft, the other end of guide wheel shaft arranges external screw thread, wheel stand is made cylinder, one end is convinced axle hole by patient analysis, for waterproof, dig the capillary groove of an annular in dead eye, the other end of wheel stand is opened dead eye, and bearing is installed in wherein, in the bearing aperture internal thread is set, the external diameter of locking nut is less than the dead eye internal diameter of wheel stand, and screw is opened at the locking nut center, and its screw just in time matches with the external screw thread of guide wheel shaft; Copper lid is made circle, and the outer end of copper lid arranges the screw edge of a knife, and its cylindrical arranges external screw thread, the installation that just in time matches with the internal thread in bearing aperture of this external screw thread.The bearing of packing in the wheel stand during installation, guide wheel are knocked in by guide wheel shaft in the bearing in the wheel stand that installs in advance bearing, then screw in locking nut at the guide wheel axle head, with screwdriver copper are covered at last to be screwed in the wheel stand.Such guide wheel has remedied the inconvenient problem of silk of wearing of existing guide wheel, and when making material province, save material thereby reach, be convenient for changing the purpose of molybdenum filament.
The beneficial effects of the utility model are that it is convenient to change molybdenum filament, saves manufacturing cost, simple in structure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is the structural representation of guide wheel;
Among the figure, 1. guide wheel, 2. guide wheel shaft, 3. wheel stand, 4. axis hole, 5. capillary groove, 6. bearing, 7. locking nut, 8. copper lid.
The specific embodiment
In the drawings, guide wheel 1 is fixed on an end of guide wheel shaft 2, the other end of guide wheel shaft arranges external screw thread, wheel stand 3 is made cylinder, one end is convinced axle hole 4 by patient analysis, for waterproof, digs the capillary groove 5 of an annular in dead eye, the other end of wheel stand is opened dead eye, bearing 6 is installed in wherein, in the bearing aperture internal thread is set, and the external diameter of locking nut 7 is less than the dead eye internal diameter of wheel stand, screw is opened at the locking nut center, its screw just in time matches with the external screw thread of guide wheel shaft, and copper lid 8 is made circle, and the outer end of copper lid arranges the screw edge of a knife, its cylindrical arranges external screw thread, the installation that just in time matches with the internal thread in bearing aperture of this screw thread.
