But said structure has only provided a kind of structure that adopts lifting motor to promote carriage and throw the roller lifting, and the utility model aims to provide a kind of throwing roller elevating mechanism different with said structure, has advantages such as rational in infrastructure, that manufacturing is easy to use equally.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of throwing roller elevating mechanism, adopt cylinder control to throw the roller lifting, have rational in infrastructure, lifting precision height, easy to operate, advantages such as cost performance is high, long service life, and can effectively improve quality of finish and the polishing efficiency of throwing roller.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of throwing roller elevating mechanism, comprise frame, described frame is provided with throws roller and motor, throws roller and motor and is in transmission connection, and described throwing roller rotates and is arranged on the carriage, carriage and frame vertically are slidingly connected, described frame is put on the shelf and is provided with power transmission shaft, and described power transmission shaft is provided with eccentric cam, and eccentric cam contacts with roller on being located at carriage, described frame is provided with cylinder, and the piston rod of cylinder flexibly connects by one-way clutch and power transmission shaft.
One-way clutch is commonly called as unilateral bearing, the machine driving basic part of transmission that also being only can single direction (clockwise direction or counterclockwise).Can only single direction (locking direction) transmission when the drive power source passive device, if when power source turns, passive device then can break away from automatically and not produce the function that any power transmits.Adopt one-way clutch to connect cylinder and power transmission shaft, thereby the promotion of cylinder piston rod is converted to the rotation of power transmission shaft.
As preferably, the end of above-mentioned piston rod and connecting rod A is hinged, and the other end of connecting rod A and connecting rod B are hinged, and connecting rod B is connected by one-way clutch with power transmission shaft.Simple and reliable for structure.
Promote angle and then the raising lifting precision that power transmission shaft rotates in order to limit cylinder, above-mentioned frame is provided with the position-limit mechanism of the piston rod stroke of restriction cylinder at every turn.
As preferably, above-mentioned position-limit mechanism comprises the limiting bracket that is fixed on the frame, the caging bolt that has been threaded on the limiting bracket, and caging bolt can contact spacing with connecting rod A.Can adjust the distance that contacts of caging bolt and connecting rod A by adjusting caging bolt, thereby adjust the piston rod stroke, simple and reasonable.
As preferably, above-mentioned one-way clutch is for changing the locking direction or can discharging the one-way clutch of locking.Can realize throwing the rollback after the roller lifting excessively like this or change and throw returning quickly behind the roller; Commutation or release as for one-way clutch can be artificial mechanism control or control automatically.
The utility model is owing to adopted above technical scheme, adopt cylinder to promote and be passed to power transmission shaft and rotate by one-way clutch, promote the carriage lifting by being fixed on power transmission shaft two ends eccentric cam, finally reach lifting and throw the purpose of roller, it is accurate, simple and reliable for structure to have adjustable height, effectively improves quality of finish and polishing efficiency.
