Abstract
A semi-locking device of a screw cap comprises a screw rod, a baffle, a fastening bolt, a sleeve and a gasket, wherein the tail end of the screw rod is provided with a flat key groove, the screw rod is connected with a flywheel spline, the baffle is close to the tail part of the screw rod spline and used for blocking the screw rod from moving upwards, the fastening bolt is in threaded connection with a flywheel threaded hole and used for fixing the baffle on a flywheel, the sleeve and the gasket are sequentially arranged on the fastening bolt from bottom to top, the fastening nut is used for fastening the baffle, the sleeve and the gasket on the flywheel, the tail end of the screw rod is provided with two flat key grooves which can be matched with the flat key groove of the screw rod and have a certain angle, the screw cap is simultaneously in threaded connection with the screw rod and fastened on the baffle, the flat key is arranged in the flat key groove matched with the screw cap and used for keeping the relative position of the screw rod and the screw cap unchanged, and the fastening screw is used for fastening the flat key on the screw rod. The half-locking device of the screw cap is suitable for locking, can be disassembled and is convenient to maintain. Can be widely applied to screw presses.
Description
Technical Field
The invention relates to a half locking device of a screw cap, which can be widely applied to a screw press.
Background
Traditional screw press, its screw rod passes through threaded connection with the screw rod cap, and the live time is longer more, and the screw rod is connected with the screw rod cap and is just more and more fastened, can cause the unable dismantlement of screw rod cap, and the maintenance is inconvenient.
Disclosure of Invention
The invention aims to provide a half-locking device of a screw cap, which is suitable for locking, detachable and convenient to maintain.
In order to achieve the purpose, the invention relates to a half locking device of a screw cap, which comprises a screw rod, a baffle, a fastening bolt, a sleeve and a gasket, wherein the tail end of the screw rod is provided with a flat key groove and is connected with a flywheel spline; two parallel key keyways of screw cap, one is the work keyway, another is reserve keyway, when needs adjusting screw and screw cap locking degree, only need use the reserve keyway of screw cap with screw cap be connected can, at this moment reserve keyway just becomes the work keyway.
The invention relates to a half-locking device of a screw cap, which has the working principle that: when the press machine works from a top view, the motor drives the flywheel to rotate anticlockwise, namely the motor drives the flywheel to rotate leftwards, the sliding block moves downwards to work, when the sliding block reaches the lowest point, the speed is suddenly reduced to 0mm/s, and the flywheel and the screw rod also stop rotating together; at the moment, the screw cap has left-handed inertia, and the screw cap is tighter as the striking times are more. After the trial run is completed, the screw cap reaches a certain tightness degree, a flat key groove is machined on the screw cap and the screw at the moment, the screw and the screw cap are fixed through the flat key, the relative position of the screw and the screw cap is kept unchanged, the locking is proper, and the locking state is good. And finally, processing another spare flat key groove of the screw cap according to a certain angle. When the locking degree of the screw and the screw cap needs to be adjusted, the screw cap and the screw are connected only by using the spare key groove of the screw cap.
According to the semi-locking device for the screw cap, the flywheel and the screw are in a spline structure, the spline connection stress is uniform, the bearing load is large, and the guidance performance is good.
In conclusion, the screw cap half-locking device can lock the screw and the screw cap with proper force, but not too tight, is suitable for locking, is neither too tight nor too loose, achieves a good locking state, and is detachable and convenient to maintain.
Drawings
The invention will be further described with reference to the accompanying drawings and examples thereof.
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the screw cap structure of FIG. 1;
fig. 3 is a top view of fig. 2.
Detailed Description
In fig. 1 to 3, the half locking device of the screw cap of the invention comprises a screw 1 with a flat key groove at the end and connected with a flywheel 10 by a spline, a baffle 2 which is close to the tail part of the screw spline and used for blocking the screw from moving upwards, a fastening bolt 3 which is in threaded connection with a threaded hole of the flywheel and used for fixing the baffle on the flywheel, a sleeve 4 and a gasket 5 which are sequentially arranged on the fastening bolt from bottom to top, a fastening nut 6 which fastens the baffle, the sleeve and the gasket on the flywheel, a screw cap 7 which is matched with the flat key groove of the screw and has a certain angle alpha, two flat key grooves which are simultaneously in threaded connection with the screw and fastened on the baffle, a flat key 8 which is arranged in the flat key groove matched with the screw and the screw cap and used for keeping the relative positions of the screw and the screw cap unchanged, and a fastening screw 9 which fastens the flat key on the screw; two parallel key keyways of screw cap, one is work keyway an, another is reserve keyway b, when needs adjustment screw and screw cap locking degree, only need use the reserve keyway of screw cap with screw cap be connected can, at this moment reserve keyway just becomes work keyway.
In summary, the screw cap half locking device of the present invention is described above as a preferred embodiment of the present invention, but not limited to the invention in any way, and although the present invention has been disclosed as the preferred embodiment, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the invention, and it is within the spirit and principle of the invention that any simple modification, equivalent replacement, and improvement made to the above embodiment may be within the scope of the invention.
