Description
Technical field
The utility model relates to a kind of stopping device that is used for the checking machine main shaft.
Background technique
The gear pair checking machine is used for the length of measuring gear pair contact area when engagement, judges the quality of gear pair with this; When detecting, need mounting fixture on the main shaft of gearwheel, so that clamping workpiece; But the main shaft of checking machine does not all have stopping device at present, and main shaft can rotate together when remover-and-replacer, is not easy to operation.
The model utility content
The purpose of the utility model is the above-mentioned deficiency to existing technology, and a kind of stopping device of checking machine main shaft is provided, and it can be located main shaft, guarantees the smooth mounting or dismounting of anchor clamps.
For achieving the above object, the stopping device of the checking machine main shaft of the utility model comprises casing, is loaded on the main shaft on the casing through bearing; It is characterized in that on main shaft, being provided with arresting disc through key, arresting disc is provided with at least one draw-in groove radially, above arresting disc, is provided with fixed cover, backing plate and handle set successively; Handle set connects with handle, and fixed cover links to each other with backing plate and is fixed on the casing, and fixed cover is provided with shoulder hole; One flip sleeve is loaded in its shoulder hole; Flip sleeve also is provided with shoulder hole, and a braking roll is loaded in the flip sleeve, and the lower end of braking roll is passed flip sleeve and fixed cover and is positioned at the top of arresting disc; One have the transmission shaft of shoulder the upper end connect with handle set through pin; Its shoulder contacts with the lower end surface of backing plate; On transmission shaft, be provided with spiral chute, in flip sleeve, be provided with the driving pin that an end is positioned at spiral chute, fixed cover and flip sleeve also are provided with vertical keyway and the feather key that matches.
During use, through handle with sleeve, handle set drives transmission shaft and rotates together; Because transmission shaft can not move up and down; Add that vertical keyway and feather key have limited flip sleeve and can not rotate, can only make flip sleeve and braking roll move up and down, when braking roll snaps in the draw-in groove of arresting disc through spiral chute and driving pin; Can locate main shaft, stop, guarantee the smooth mounting or dismounting of anchor clamps.
As the further improvement of the utility model, said transmission shaft lower end also is provided with blind hole, the spring that is provided with steel ball successively and contacts with braking roll from top to bottom in the blind hole; Can apply pretightening force to braking roll, prevent the braking roll swing;
As the further improvement of the utility model, also be provided with blind hole in the said handle set, be provided with spring and steel ball in the blind hole from top to bottom successively, be provided with the locating slot that cooperates with steel ball in the backing plate upper-end surface; Can limit the limit position that braking roll moves up and down.
In sum, the utility model can be located main shaft, guarantees the smooth mounting or dismounting of anchor clamps.
