Abstract
The utility model discloses a rotation prevention pin shaft which comprises a shaft body. A key slot is arranged on the end surface of the shaft body along the radial direction. In the utility model, the key slot is arranged on the end surface of the pin shaft along the radial direction and then the key slot on the pin shaft is connected with a key slot on a hinge beam through a key during use, so that the function of preventing rotation is realized and the dismounting of the pin shaft in the maintenance process is more convenient.
Description
Technical field
The utility model relates to a kind of anti-rotation bearing pin.
Background technique
In the process that synthetic diamond is produced, because the work of cubic hinge press and intermittently alternately appearance of state, therefore, the bearing pin of hinge beam also is subjected to corresponding alternating force, under the effect of this alternation active force, the bearing pin of part press has the phenomenon of rotation, has influenced the using effect of press, there is certain potential safety hazard, and makes the dismounting when keeping in repair comparatively difficult.
The model utility content
The purpose of this utility model provides a kind of bearing pin of rotating of can preventing.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of anti-rotation bearing pin comprises axis body, and the axis body end face radially is provided with keyway.
The utility model adopts radially offers keyway at pin roll end face, with key the keyway on the bearing pin is connected with keyway on the hinge beam in use, thereby plays the effect of rotating of preventing, it is comparatively convenient that bearing pin in the maintenance process is dismantled.
