Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinders, in particular to a stable hydrostatic support and guiding hydraulic cylinder. Background Technique

[0002] Hydraulic transmission and its control technology are widely used in the machinery industry due to their unique advantageous properties. Hydraulic cylinders are the most commonly used components in hydraulic technology to achieve reciprocating motion. A hydraulic cylinder is a widely used industrial automation device, and its structure generally installs a guide sleeve in the cylinder barrel, and then installs components such as a piston and a piston rod in the guide sleeve.

[0003] According to a hydrostatic support and guiding hydraulic cylinder disclosed in the patent publication number CN 110792654 B, the guiding slide rod of this device can play a role in axially rotating and limiting the cross guiding strip, so that the extended hydraulic rod can only reciprocate in the cylinder body and cannot generate axial rotation in the cylinder body, thereby preventing the hydraulic cylinder from being used in occasions where only the reciprocating movement of the connected part in the horizontal or vertical direction is required, and the rotating device can drive the cylinder body and the hydraulic rod to rotate synchronously. When there is no rotation limiting device between the hydraulic rod and the cylinder body, the phenomenon of separated rotation of the hydraulic rod or the cylinder body will occur, thereby affecting the installation and use effect of the hydraulic cylinder body on the connected part; however, the side of this device does not have a protective effect, and relatively prominent objects in the outside world are likely to cause damage to the cylinder body, thus affecting the applicability of the device.

[0004] Therefore, we propose a stable hydrostatic support and guiding hydraulic cylinder to solve the problem. Content of the Utility Model

A positioning block 314 is fixedly connected to the side wall of the protection plate 312. A clamping hole 315 is opened in the middle of the positioning block 314. A buffer plate 313 is fixedly connected to the outside of the protection plate 312. A sliding groove 316 is opened on the side wall of the end cover 1. A sliding rod 317 is fixedly connected to the inner wall of the sliding groove 316. A slider 318 is slidably connected to the outer wall of the sliding rod 317. A first spring 319 is fixedly connected to the inner wall of the sliding groove 316. A connecting rod 3110 is fixedly connected to the outside of the slider 318. One end of the connecting rod 3110 is movably connected to a clamping rod 3111. A limiting block is fixedly connected to the outer end of the clamping rod 3111. A second spring 3112 is fixedly connected to the outside of the connecting rod 3110. A positioning groove is opened on the side wall of the end cover 1.

[0027] In this embodiment, the positioning block 314 is clamped with the positioning groove, and the inner side of the connecting rod 3110 is attached to the outer side of the positioning block 314. Through the cooperation of the protection plate 312 and the buffer plate 313, the cylinder body 2 can be protected, and the cylinder body 2 can be prevented from being damaged by external protruding objects.

[0028] Furthermore, one end of the first spring 319 is fixedly connected to the slider 318, the clamping rod 3111 is clamped with the clamping hole 315, and one end of the second spring 3112 away from the connecting rod 3110 is fixedly connected to the limiting block.
