As an embodiment of the present invention, two side surfaces of the hollow tube 3 are provided with brushes 8; the brush 8 is arranged close to one end of the hollow pipe 3 provided with the through groove 11; the during operation, when changing the working face of sanding block 5, impurity on the 5 terminal surfaces of sanding block is touched by brush 8 on the hollow tube 3, then brush 8 can clear up the working face surface that has just worked, because the working face of polishing comprises a plurality of sanding blocks 5, when making the impurity of brush 8 clearance can be through changing the sanding face, gap between sanding block 5 leaves, can not remain in the middle of two shield 6, thereby when making the working face of changing sanding block 5, sanding block 5's working face surface does not have the glass piece, and then improved sanding block 5's the quality of polishing, optical glass's the effect of polishing has been strengthened.
A method for preparing an optical glass production grinding tool is suitable for the optical glass production grinding tool and comprises the following steps:
s1: when the grinding tool is manufactured, a worker firstly manufactures the rotating shaft 1, the hollow pipe 3, the round sleeve 2 and the dustproof cover 6 through a milling machine, and then manufactures the grinding block 5 and the long shaft 9 through a numerical control machine;
s2: a worker taps threads on the rotating shaft 1 and the surface of the round sleeve 2 contacting the rotating shaft 1 through a milling machine; then, through grooves 11 are formed in the hollow pipe 3 through a drilling machine, concave holes 10 are formed in the dustproof cover 6, round holes are formed in the outer wall of the round sleeve 2 and the long shaft 9, and finally round holes are formed in the grinding block 5;
s3: the staff links firmly and twines wire rope 4 on rotation axis 1, install rotation axis 1 and round cover 2 together through the screw thread after that, then make wire rope 4 pass round hole on the round cover 2 and pass round cover 2, then annular equidistance links firmly hollow tube 3 on the outer wall of round cover 2, again make wire rope 4 pass hollow tube 3, and install brush 8 on the both sides face of hollow tube 3, then link firmly shield 6 installation on the same horizontal plane at round cover 2 both ends, install major axis 9 on sanding block 5 immediately, wire rope 4 wears out from the concave hole 10 of shield 6 at last, then wire rope 4 above shield 6 is tied on major axis 9 through the round hole on major axis 9, wire rope 4 below shield 6 links firmly on major axis 9, thereby the preparation to optical glass production grinding apparatus has been accomplished.
The specific process is as follows:
when the polishing machine works, a worker firstly installs the polishing machine on a polishing machine through a round hole formed in a rotating shaft 1, then when polishing optical glass with low requirement on roughness, firstly, the initial working surface of a polishing block 5 is a rough polishing surface, then the worker rotates the rotating shaft 1, the rotating shaft 1 drives a steel wire rope 4 to rotate, so that the steel wire rope 4 wound on the rotating shaft 1 is tightened, and then the steel wire rope 4 drives the corresponding polishing block 5 to move towards the rotating shaft 1; the hollow pipe 3 is fixedly connected to the round sleeve 2 and corresponds to the grinding block 5, and when the steel wire rope 4 drives the grinding block 5 to move towards the direction of the rotating shaft 1, one end of the hollow pipe 3 is in contact with the grinding block 5, so that the grinding block 5 can be propped against to move towards the direction of the rotating shaft 1; then, two opposite acting forces of the pulling force of the steel wire rope 4 and the abutting force of the hollow pipe 3 are used for fixing the polishing block 5, then the optical glass is roughly ground, and the rotating shaft 1 and the round sleeve 2 are fixed more tightly in the polishing process due to the fact that the threaded connection direction of the rotating shaft 1 and the round sleeve 2 is opposite to the polishing direction; when the optical glass with high requirement on roughness needs to be polished, a worker rotates the dustproof cover 6, the dustproof cover 6 is fixedly connected with the round sleeve 2, the round sleeve 2 is in threaded connection with the rotating shaft 1, the dustproof cover 6 drives the rotating shaft 1 to rotate, so that the steel wire rope 4 wound on the rotating shaft 1 is loosened, then the worker pulls the polishing block 5 out of the working surface of the turning polishing block 5, turns the fine grinding surface out, then rotates the rotating shaft 1 to tighten the steel wire rope 4 wound on the rotating shaft 1, finally fixes the polishing block 5 by means of two opposite acting forces of the pulling force of the steel wire rope 4 and the interference force of the hollow pipe 3, and then starts to finish the optical glass; so that the optical glass requiring different roughness is polished by changing the working surface of the polishing block 5.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention.
