The specific embodiment
Referring to Fig. 1-4, shown the grinding attachment with quick-disassembly structure of the present invention.
Described grinding attachment comprises grinding machine head 1 and the dismountable grinding knife tool 2 be installed on grinding machine head 1 that is arranged at the grinding machine front end, described grinding knife tool 2 can be diamond grinding head, be provided with drive rod 3 in described grinding machine head 1, described drive rod 3 is rotatable to be placed in grinding machine head 1 inside and to drive rotation by the drive unit (not shown), be provided with bearing and locating ring 4 between described drive rod 3 and grinding machine head 1, referring to Fig. 2, described locating ring 4 is positioned bearing between described drive rod 3 and grinding machine head 1.
Referring to Fig. 2, shown the concrete structure of described drive rod 3, described drive rod has hollow via-hole, is fixed with knife bar 7 in described hollow via-hole, and described knife bar 7 is fixed in described hollow via-hole by flange and the retaining element that is positioned on flange.
Described knife bar 7 comprises the circular knife bar body 71 of truncated cone, the front end of described knife bar body 71 is provided with a plurality of through holes 72 that arrange along periphery, be provided with lock uint 8 in knife bar 7, described lock uint 8 comprises closure 81 and lower closure 82, described upper closure 81 and lower closure 82 are fixedly arranged in the endoporus of described knife bar 7, preferably, described upper closure 81 and lower closure 82 are by engaging in conjunction with being fixed, and described snap-in structure can be screw and fixes or connect and fix.
There is accommodation space between closure 81 and lower closure 82 on described, a plurality of balls 10 that number is corresponding with through hole 72 numbers are arranged in described accommodation space, known is, the diameter of described ball 10 is greater than the diameter of described through hole 72, but be less than 7/6 of described through hole 72 diameters, thus, can avoid ball 10 to come off from through hole 72, guarantee that ball 10 can stretch out sufficient length from through hole 72 simultaneously.
The below of described upper closure 81 is provided with the gland 9 that can move up and down in the endoporus of described knife bar 7, one elastic component is arranged between described upper closure 81 and described gland 9, optionally, described elastic component is powerful stage clip, described gland 9 is provided with a plurality of upper stitching surface 91 coordinated with a plurality of balls 10, known, the quantity of described upper stitching surface equates with the quantity of ball 10, and described upper stitching surface is the indent semicircle sphere.
The top of described lower closure 82 is installed with upper cover 11, described upper cover 11 is boss-shaped, outer rim at described upper cover 11 is provided with a plurality of lower stitching surface 111 coordinated with a plurality of balls, known is, the quantity of described lower stitching surface equates with the quantity of ball 10, described lower stitching surface is the indent semicircle sphere, thus, described ball 10 can be contained by described upper stitching surface 91 and described lower stitching surface 111, simultaneously, utilization is elastic component between closure 81 and described gland 9 on described, can carry out ball 10 urgently, to order about ball 10, exposes described through hole 72.
For ease of dismounting, be provided with lower cover 12 below upper cover 11, described lower cover 12 is fixed in described upper cover by screw, and the upper projection of described lower cover stretches into the inner via hole of described upper cover 11, and the lower flange of described lower cover 12 is positioned in the chucking hole of described lower closure 82.
Be provided with retainer ring 5 and lower retainer ring 6 in the mesopore of described grinding knife tool 2, fixed ring 5 and lower retainer ring 6 mutually lean and are fixed on described grinding knife tool 2 by flange and the retaining element that is positioned on flange respectively, be provided with the bellmouth 51 coordinated with described knife bar 7 in fixed ring 5, thus, the circular knife bar body 71 of truncated cone can stretch in described bellmouth 51 to form urgent location, be provided with annular spacing preiection 52 in the centre position of described bellmouth 51, be provided with the locating slot 53 coordinated with described ball 10 of annular below described spacing preiection 52, described locating slot 53 can hold described ball 10, thereby after ball 10 enters locating slot 53, the spacing preiection 52 at locating slot 53 rears stops ball 10 to break away from.
Below specifically describe unloading process of the present invention.
Referring to Fig. 5, shown the schematic diagram connected with the grinding attachment of quick-disassembly structure of the present invention, when being contained on grinding machine head by grinding knife tool, can insert by the knife bar body of taper the bellmouth of the upper retainer ring of grinding knife tool, now, the ball that is positioned at knife bar is subject to the extruding of bellmouth, move inward, in through hole, do not stretch out, and gland is oppressed by ball, compression elastic piece moves up, ball can not stretch out through hole, and fall into locating slot along with ball after crossing spacing preiection, ball can stretch out through hole, the restoring force compressing gland of flexible member moves downward, make stitching surface and lower stitching surface tightly oppress ball, with spacing preiection, jointly avoid ball to come off from locating slot.
Once need to split out grinding knife tool, fixedly, after any of grinding machine head or grinding knife tool, another is carried out to drawing, the through hole on the knife bar body is oppressed ball, impel ball to move inward, thereby make gland be oppressed by ball, the power that overcomes flexible member moves upward, ball falls between the upper stitching surface and lower stitching surface in through hole, to deviate from from locating slot, and can cross spacing preiection, thus the positioning action of losing, grinding machine head and grinding knife tool break away from mutually.
As can be seen here, the present invention has following advantage:
1, adopt ball to coordinate locating slot, accurate positioning, difficult drop-off in grinding process;
2, by the restoring force of flexible member, ball is oppressed, cargo handling process is very simple and practical, can realize dismounting fast and safely;
3, safeguard and change conveniently, having improved efficiency, having reduced cost.
It is evident that, above description and record are only for example rather than in order to limit disclosure of the present invention, application or use.Although described in an embodiment and be described in the drawings embodiment, but the optimal mode that the present invention does not limit by the accompanying drawing example and the conduct of describing is in an embodiment thought at present to be to implement the specific examples of instruction of the present invention, scope of the present invention will comprise any embodiment of the specification that falls into front and appended claim.
