In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.
The grinding wheel cover of the surface grinding machine for preventing the door lock bolt from falling off as shown in fig. 1 and 4 comprises a grinding wheel cover shell 1, a grinding wheel cover shell door 2, an anti-falling bolt 3 and a grinding wheel cover shell door lock nut 4, wherein one side of the grinding wheel cover shell door 2 is hinged with the grinding wheel cover shell 1, and the other side of the grinding wheel cover shell door 2 is connected with the grinding wheel cover shell 1 through an anti-falling mechanism;
the anti-falling mechanism comprises an anti-falling bolt 3 and a grinding wheel cover door lock nut 4, and the anti-falling bolt 3 penetrates through a through hole in the grinding wheel cover door 2 and is in adaptive threaded connection with a threaded hole in the grinding wheel cover door lock nut 4; the front end of the anti-falling bolt 3 is a threaded section 5 matched with a threaded hole in the grinding wheel cover shell door lock nut 4, and the rear end of the anti-falling bolt 3 is a smooth end 6.
As a further optimization of the above embodiment:
in this embodiment, the anti-slip bolt 3 is preferably a star bolt.
In this embodiment, the through hole on the wheel guard shell door 2 is preferably of an internal thread structure. The internal thread structure is matched with the external thread structure of the thread section 5, and preferably an M8 thread structure is adopted.
In this embodiment, preferably, the thread section 5 is an external thread structure; the threaded hole on the wheel guard shell door lock nut 4 is of an internal thread structure, and preferably adopts an M8 thread structure.
In this embodiment, preferably, the inner diameter of the through hole on the grinding wheel housing door 2 is smaller than the outer diameter of the threaded section 5, so that the star bolt cannot fall off from the grinding wheel housing door, and the phenomenon that the star bolt falls off and needs to be found or cannot be found is avoided.
Preferably, in this embodiment, the length of the smooth end 6 is 3-4 mm. Further, the diameter of the smooth end 6 is smaller than the diameter of the threaded segment 5.
The principle of the utility model is that:
changing a hole of a star-shaped bolt phi 9 arranged on the original grinding wheel cover shell door into a hole of M8; the root of the anti-drop star bolt M8 is provided with a section of column which is 3-4mm and is made into phi 6, and during assembly, the star bolt M8 is screwed into the hole of the M8 on the grinding wheel cover shell door until the door and the bolt are not engaged with each other any more in a threaded manner.
When the door of the grinding wheel cover shell needs to be locked with the grinding wheel cover shell, the star-shaped bolt is screwed into the door lock nut on the grinding wheel cover shell and is screwed tightly. If the door of the grinding wheel cover needs to be opened, the star bolt only needs to be screwed off from the grinding wheel cover shell, and the star bolt cannot fall off from the door of the grinding wheel cover shell because the outer diameter of the M8 thread on the star bolt is larger than the inner diameter of the M8 screw hole on the grinding wheel cover shell door, so that the phenomenon that the star bolt falls off and needs to be found or cannot be found is avoided. The invalid working hours caused by finding the star-shaped bolt and the potential safety hazard caused by the loss of the bolt are eliminated.
The utility model provides a star bolt can not drop from the door of emery wheel housing, just no longer appears the star bolt and drops the phenomenon that odd needs look for or can not find, eliminates the invalid man-hour that looks for star bolt and produce and the potential safety hazard that the bolt lost and brought.
The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiments, and although the present invention has been disclosed with the preferred embodiments, it is not limited to the present invention, and any skilled person in the art can make some modifications or equivalent embodiments without departing from the scope of the present invention, but all the technical matters of the present invention are within the scope of the present invention.
