Drawings
FIG. 1: the utility model relates to a three-dimensional structure diagram.
FIG. 2: the cross-sectional structure of the present invention.
FIG. 3: the enlarged view of part A of FIG. 2 of the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Please refer to fig. 1-3;
the electric cylinder has the innovation points that the steel sleeve 32 is adopted to replace a copper sleeve, the steel sleeve 32 is high in hardness and has good wear resistance, the overall durability is improved, the end cover 3 is improved on the basis that the steel sleeve 32 is high in hardness, the flange 31 is arranged on one side of the end cover 3 along the periphery of the opening to form an installation position for installing the steel sleeve 32, the steel sleeve 32 can be fixed on the inner surface of the flange 31 in an interference fit mode during installation, the installation is more convenient compared with the copper sleeve in need of additional auxiliary installation, for example, a screw hole needs to be formed in the end cover 3 during installation of the copper sleeve, a screw is used for fixing and the like, after the steel sleeve 32 is installed, the inner diameter of the steel sleeve 32 needs to be finely polished according to the outer diameter of the piston rod 23, so that the inner wall of the steel sleeve 32 is smooth and simultaneously meets the size of the piston rod 23;
since the steel sleeve 32 is fixedly mounted on the end cover 3 by interference fit, and the size of the steel sleeve 32 extending into the end cover 3 is difficult to be grasped, a limit part 33 is formed by extending the steel sleeve 32 into the opening on the side of the end cover 3 away from the flange 31, and the steel sleeve 32 is mounted in place when abutting against the limit part 33.
Lubricating oil is usually needed for lubricating the electric cylinder, the lubricating oil is usually injected into the cylinder barrel 21 and fully distributed on the surface of the piston rod 23, and the lubricating oil can be taken out by the piston rod 23 when the screw rod mechanism 22 drives the piston rod 23 to move, so that the limiting part 33 is utilized to be provided with the placing groove 34 in the limiting part, the placing groove 34 is internally provided with the Y-shaped sealing ring 35, when the screw rod mechanism 22 drives the piston rod 23 to move, the lubricating oil on the surface of the piston rod 23 can be blocked by the Y-shaped sealing ring 35, most of the lubricating oil can be retained in the cylinder barrel 21, and in addition, the Y-shaped sealing ring 35 can block external dust from entering, so that the precision is prevented from being influenced;
in addition, the driving device is formed by combining a servo motor and a speed reducer, so that the torque can be effectively increased to improve the heavy-load performance, and the accuracy of the electric cylinder is effectively improved by matching with a screw rod mechanism, specifically a ball screw.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
