Description

Technical Field

[0001] The utility model relates to the technical field of electric cylinders, in particular to an anti-deviation mechanism and a piston rod supporting structure of a piston-type electric cylinder. Background Art

[0002] An electric cylinder is an electric drive device that converts the rotational motion of a motor into the linear reciprocating motion of the electric cylinder. It generally includes a cylinder body, a motor, a travel switch, a push rod, and a transmission device. Driven by the motor, the push rod performs a linear reciprocating motion relative to the cylinder body to achieve the pushing function. It has been widely used because of its simple structure, high transmission efficiency, and reliable operation.

[0003] In the prior art, there are many types of electric cylinders, such as rotary electric cylinders, piston electric cylinders, slide electric cylinders, etc. Among them, piston electric cylinders generally use various joints to eliminate the eccentric load during use to prevent the cylinder piston rod from being deflected due to eccentric load during operation, thereby preventing the cylinder piston rod from being deflected.

[0004] However, when the electric cylinder piston rod is extended too long, the horizontality of the electric cylinder piston rod cannot be guaranteed. During the repeated movement of the piston rod, the piston rod will be deflected, and the friction between the piston and the cylinder body will cause the piston to wear and cause damage to the electric cylinder.

[0031] Embodiment 3

[0032] On the basis of the second embodiment, three inner square sleeves 24 are provided and are evenly arranged in the cover shell 7. A limit rod 25 is installed on one side of the inner square sleeve 24, and the limit rod 25 is sleeved and installed in the cover shell 7. A square hole 26 is opened on one side of the T-shaped slide groove 8. A connecting block 27 is fixedly installed on one side of the L-shaped slider 9.

When the annular protrusion 29 rotates to the square hole 26 opened on one side of the T-shaped slide groove 8, the annular protrusion 29 slides in the rectangular groove 28 opened on one side of the connecting block 27, thereby causing the L-shaped slide 9 to move up and down, thereby causing the stabilizing block 11 to approach or move away from the electric cylinder piston rod 17, thereby providing stable support for the electric cylinder piston rods 17 of different diameters. When the arc surface of the stabilizing block 11 fits with the outer ring surface of the electric cylinder piston rod 17, the deflection caused by the electric cylinder piston rod 17 extending too long can be reduced, thereby ensuring the horizontality of the electric cylinder piston rod 17, and also preventing the electric cylinder piston rod 17 from being pressed down or lifted up when the electric cylinder piston rod 17 is subjected to excessive force, thereby protecting the electric cylinder piston rod 17 from tilting, which is beneficial to increasing the service life of the electric cylinder and improving the use efficiency.
