The utility model adopts following technical scheme:
Novel diamond disc, the axle center part of this diamond disc have the shaft coupling hole of perforation, it is characterized in that: the inner in described matrix shaft coupling hole is that cylindrical hole, outer end are for linking to each other with cylindrical hole and the outside coniform hole of hole enlargement gradually.
Described diamond disc comprises the matrix of disk shape and the diamond segment that is welded on the matrix periphery, and described shaft coupling hole is arranged at the place, axle center of matrix.
The utility model also provides the transmission joint of a kind of diamond disc and mandrel, comprise above-mentioned diamond disc and mandrel, the tail end of mandrel has boss shoulder, thread segment, also comprise the axle core of tubulose and be set in a clamping element of core outer peripheral face, one end side face of axle core is provided with cone table, the middle part of matching with described coniform hole and has the internal thread hole that matches with the mandrel thread segment, and the middle part of clamping element is provided with the perforation that is communicated with the inner cylindrical hole of saw blade; Described axle core is placed through in the perforation of the shaft coupling hole of saw blade and clamping element, and revolve on the thread segment of being located at the mandrel end, clamping element is located between the boss shoulder and saw blade inner face of mandrel, diamond disc is gripped with axle core, clamping element by revolving the mandrel of establishing tension; The axle core outer face after installing and fixing and the outer face of diamond disc maintain an equal level.
Mounting means of the present utility model: at first, offer one at the matrix axle center part of diamond disc and connect the shaft coupling hole, the inner in this shaft coupling hole is that cylindrical hole, outer end are for linking to each other with cylindrical hole and the outside coniform hole of hole enlargement gradually, the axle core is plugged in the shaft coupling hole of saw blade, and the cone table of tape spool core and the coniform hole in shaft coupling hole are fitted, then, clamping element is sleeved on the axle core outer peripheral face that stretches out outside the shaft coupling hole, at last, utilize instrument that the thread segment of mandrel tail end is screwed in the internal thread hole of axle core, assisting down of clamping element, a mandrel and an axle core are screwed.Mandrel after tightening is strained mutually with the axle core, and clamping element, saw blade are clamped between the boss shoulder and saw blade inner face that are located in mandrel of mandrel, diamond disc is gripped with axle core, clamping element by revolving the mandrel of establishing tension; The axle core outer face after installing and fixing and the outer face of diamond disc maintain an equal level, and the afterbody of mandrel is arranged in the internal thread hole of a core.
The utlity model has following advantage:
The novel diamond disc that the utility model provides, its axle center part have the shaft coupling hole of perforation, and the inner in this shaft coupling hole is that cylindrical hole, outer end are for linking to each other with cylindrical hole and the outside coniform hole of hole enlargement gradually.Use when installing, utilize an end side face to be provided with tapered axle core, to be sleeved on a clamping element of core periphery,, down saw blade is fixedly clamped, saw blade firmly is connected with mandrel the auxiliary of clamping element by tension mandrel and the axle core of being threaded.Saw blade outer face after the installation is smooth, and all members all are positioned in the saw blade outer face, and the saw blade outer face after the feasible assembling can be close to stone surface fully and carry out horizontal resection, and the cutting angle of saw blade is unrestricted, has enlarged the scope of application of saw blade; And the potential safety hazard that has solved the frayed easily and attenuation of locking nut in the cutting process even got loose and brought.
