Description
Technical Field
The utility model relates to a tear resistance testing arrangement is torn to grinding wheel.
Background
The grinding wheel is used for grinding and cutting a workpiece to be processed by means of high-speed rotation of the grinding wheel. After the grinding wheel is formed, the stability difference of the internal structure of the grinding wheel easily causes the tearing of individual grinding wheel during high-speed rotation, so that safety accidents of equipment and personnel are caused, and therefore the tearing resistance test needs to be carried out before the grinding wheel is put in storage.
SUMMERY OF THE UTILITY MODEL
The utility model provides a tear resistance testing arrangement is torn to grinding wheel to solve the technical problem of the tear resistance of test grinding wheel.
The technical scheme of the utility model is realized like this: the grinding wheel tear resistance testing device comprises a shell, wherein a shaft sleeve is arranged in the shell, a rotating shaft used for mounting a grinding wheel is arranged on the shaft sleeve in a rotating mode, and the rotating shaft is driven to rotate through a motor.
Furthermore, the rotating shaft is provided with stop protrusions for stopping the grinding wheel from moving downwards and pressing blocks for pressing the grinding wheel at intervals, and the pressing blocks are in threaded fit with the rotating shaft.
Furthermore, a separating block is arranged between the stop protrusion and the pressing block, the separating block is in sliding fit with the rotating shaft, and a pre-tightening elastic piece is arranged between the pressing block and the separating block.
Further, the pre-tightening elastic piece is a spiral compression spring.
Furthermore, a top cover is arranged at the upper end of the shell.
Further, the shell is barrel-shaped.
Further, the shell is made of aluminum alloy.
By adopting the technical scheme, the beneficial effects of the utility model are that: the utility model discloses a tear resistance testing arrangement is torn to grinding wheel's casing is equipped with the axle sleeve, and the axle sleeve rotates and is equipped with the rotation axis that is used for installing the grinding wheel, and the grinding wheel is high-speed rotatory under the drive of rotation axis, has played the effect of tearing resistance when testing the high-speed rotation of grinding wheel.
