The utility model provides a diamond scribing cutter, among the effectual prior art that has solved, the scribing cutter is overall structure, yielding, changes more troublesome, difficult radiating problem, and the technical scheme of its solution is, including annular main part, have a plurality of square blades that are the circumference equipartition on the main part terminal surface, have a plurality ofly be circumference equipartition and with the recess of blade one-to-one on the main part terminal surface, the blade is arranged in the recess, blade outer fringe four sides are the cutting edge, a blade side stretches out the recess and places the recess outside in, runs through in the middle of the blade and has compression screw, threaded connection between compression screw and the main part, the utility model discloses the structure is ingenious, miniaturizes the scribing cutter, forms the structure that can splice to this reduces the deformation of scribing cutter itself as far as possible, and the multi-disc combination makes whole cutter do benefit to the heat dissipation, easily changes, increases the utilization ratio of stage property.

Description

Diamond scribing knife

Technical Field

The utility model relates to a scribing knife makes technical field, especially a diamond scribing knife.

Background

The scribing knife is a tool specially used for processing optical glass. Most of the existing scribing cutters are manufactured integrally, and the rotating speed of a main shaft is very high, so that the requirements on the dynamic balance and the static balance of the scribing cutters are strict. The scribing cutter is light and thin, the area is relatively large, the surface of the scribing cutter is easy to bend and deform during storage, and once defects occur, the whole scribing cutter needs to be scrapped; in addition, the replacement of the existing scribing knife is also a difficult problem, and the process is complicated. When in use, the whole scribing cutter can be replaced as long as the conventional scribing cutter is broken; the cutting edge outer fringe is because the heat dissipation is untimely, appears cutting the product unqualified easily.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming prior art's defect, the utility model provides a diamond scribing sword, among the effectual prior art of having solved, the scribing sword is overall structure, yielding, and it is more troublesome to change, the radiating problem of difficult.

The technical scheme of its solution is, including annular main part, have a plurality of square blades that are the circumference equipartition on the main part terminal surface, have a plurality of recesses that are the circumference equipartition and with the blade one-to-one on the main part terminal surface, the blade is arranged in the recess, and blade outer fringe four sides are the cutting edge, and a blade side stretches out the recess and places the recess outside in, and it has housing screw to run through in the middle of the blade, threaded connection between housing screw and the main part.

The utility model discloses the structure is ingenious, and is miniaturized the scribing cutter, forms the structure that can splice to this reduces the deformation of scribing cutter itself as far as possible, and the multi-disc combination makes whole cutter do benefit to the heat dissipation, and is liable to change, increases the utilization ratio of stage property.

Detailed Description

The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.

By figure 1 to 3, the utility model discloses an annular main part 1 has a plurality of square blade 2 that are the circumference equipartition on the 1 terminal surface of main part, have a plurality of circumference equipartitions and with the recess 3 of 2 one-to-ones of blade on the 1 terminal surface of main part, in recess 3 was arranged in to

blade

2, 2 outer fringe four sides of blade were the cutting edge, 2 sides of blade stretched out recess 3 and arranged in the recess 3 outside, 2 middle running-through of blade have housing screw 4, threaded connection between housing screw 4 and the main part 1.

In order to further fix a position the blade 2 and prevent the blade 2 from shaking in the groove 3, the groove 3 is U-shaped, the three sides of the groove 3 are provided with convex blocks 5, the outer edge of the blade 2 is provided with a clamping groove, and the convex blocks 5 are arranged in the clamping groove.

In order to reduce the situation of edge breakage, the four corners of the blade 2 are rounded.

During the use, arrange recess 3 in with blade 2 as required to protruding piece 5 is arranged in the draw-in groove and is made blade 2 fixed firm, later, need polish the knife edge again, concrete operation: after the fixing of each blade 2 is completed, the main body 1 is installed on the rotating shaft, and then the cutter repairing plate is arranged on one side of the main body 1 according to a certain angle, and the cutting edges of the newly replaced blades 2 are adjusted on a plane.

It is noted that each time the blade 2 is replaced, the entire disc of blades 2 needs to be ground and calibrated.

In the scheme, each blade 2 is provided with four cutting edges, so that the service life of the blade 2 is greatly prolonged, and the blades 2 are spaced from each other, so that the integral heat dissipation performance is good; the single blade 2 is small in size, not easy to deform and convenient to store.

Utility model structure is ingenious, miniaturizes the scribing cutter, forms the structure that can splice to this reduces the deformation of scribing cutter itself as far as possible, and the multi-disc combination makes whole cutter do benefit to the heat dissipation, easily changes, increases the utilization ratio of stage property.
