Description
Technical Field
The utility model belongs to grinding machine accessory field, concretely relates to grinding machine emery wheel structure.
Background
The traditional grinding wheel flange is connected by common screws, so that when the grinding wheel is replaced, one hand is required to support the grinding wheel, and the other hand is required to detach the screws, which wastes time and labor; meanwhile, the frequent replacement of the grinding wheel to disassemble the flange easily causes the damage of the thread hole on the flange, and the grinding wheel cannot be locked, thereby causing safety accidents.
Therefore, a new technical solution is needed to solve the above technical problems.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: for solving the problem that current emery wheel structure exists when changing, the utility model provides a grinding machine emery wheel structure.
The technical scheme is as follows: a grinding wheel structure of a grinding machine comprises a grinding head flange, a positioning pin, a grinding wheel flange, a grinding wheel body and a pressing block for fixing the grinding wheel body on the lower surface of the grinding wheel flange; the upper surface of the grinding wheel flange is provided with a positioning hole which is matched with the positioning pin to realize positioning action; the grinding head flange is detachably connected with the grinding wheel flange, and in the connecting process, the positioning pin is positioned in the positioning hole to realize positioning; when the positioning device is detached, the positioning release is realized by adjusting the position of the positioning pin in the positioning hole.
Further, the positioning hole comprises a positioning hole wide end and a positioning hole narrow end; the positioning pin comprises a positioning pin wide end and a positioning pin narrow end; the narrow end of the positioning pin is fixed on the lower surface of the grinding head flange, and the width of the wide end of the positioning pin is smaller than that of the wide end of the positioning hole and larger than that of the narrow end of the positioning hole; the width of the narrow end of the positioning pin is smaller than that of the narrow end of the positioning hole.
Furthermore, the length of the narrow end of the positioning hole is longer than that of the wide end of the positioning hole.
Furthermore, the number of the positioning pins is 1 or more; the number of the positioning holes is consistent with that of the positioning pins.
Furthermore, the grinding wheel body is detachably connected with the pressing block.
Further, the detachable connection comprises a connection fixed through matching of a screw and a nut.
Has the beneficial effects that: compared with the prior art, the utility model, have following advantage:
(1) The grinding wheel can be quickly replaced by adding a quick positioning structure between the grinding head flange and the grinding wheel flange;
(2) Screw holes on the flange are eliminated, the structure is fixed by a hardened screw, and the damaged nut and screw can be replaced at any time.
Drawings
FIG. 1 is an exploded view of the present invention;
fig. 2 is a cross-sectional view of the present invention.
Detailed Description
The invention will be further elucidated with reference to the drawings.
As shown in fig. 1 and 2, the utility model discloses a grinding machine grinding wheel structure, including bistrique flange 1, locating pin 2, grinding wheel flange 3, stiffened nut 4, emery wheel body 5 and briquetting 6.
The grinding head flange 1 is matched with the hardened nut 4 through a screw to be fixed with the grinding wheel flange 3, meanwhile, a positioning pin fixed on the grinding head flange 1 is correspondingly arranged in a positioning hole 31 on the grinding wheel flange 3, the positioning hole 31 comprises a wide end and a narrow end, and the size of the wide end is the size which can enable the positioning pin 2 to vertically enter or vertically exit; the narrow end is of a size that does not allow the positioning pin 2 to enter or exit vertically; the narrow end is longer in length than the wide end. Similarly, for the matching positioning action, the positioning pin 2 comprises a wide end and a narrow end, the upper surface of the narrow end of the positioning pin 2 is fixed on the lower surface of the grinding head flange 1, the size of the wide end of the positioning pin corresponds to that of the wide end of the positioning hole, namely, the wide end of the positioning pin can vertically enter or vertically exit from the wide end of the positioning hole and cannot vertically enter or vertically exit from the narrow end of the positioning hole, and the narrow end of the positioning pin can be placed into the narrow end of the positioning hole. Generally, the number of the positioning pins is the same as that of the positioning holes, and may be one or more, and preferably, 3 positioning pins are generally used.
The grinding wheel body 5 is fixed on the grinding wheel flange through the pressing block 6, specifically, the pressing block 6 comprises a base 61 and a protrusion 62 arranged on the surface of the base 61, the protrusion 62 corresponds to a hollow area in the middle of the grinding wheel body 5, the width of the base 61 is larger than the hollow area in the middle of the grinding wheel body 5, the pressing block 6 and the grinding wheel flange 3 are respectively located at the lower end and the upper end of the grinding wheel body 5, and when the pressing block 6 is fixed with the grinding wheel flange 3, the grinding wheel body 5 can be fixed. When the grinding wheel flange is installed, the bulge upwards penetrates through the middle of the grinding wheel body 5 and is in contact with the lower surface of the grinding wheel flange 3, and the pressing block 6 is matched with the hardened nut through screws to fix the pressing block and the grinding wheel flange 3.
When the grinding wheel body is worn to a certain degree and needs to be replaced, the grinding wheel flange is rotated to a certain angle after the screw is loosened, the pressing block is taken down after the screw in the middle of the grinding wheel is loosened, the grinding wheel is replaced, the pressing block is tightly pressed by tightening the screw after the screw is replaced, the grinding wheel flange is supported by two hands to be aligned to the positioning hole to rotate for a certain angle, and the screw is tightened.
