Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric cylinder technology, specifically to an anti-rotation guide structure for an electric cylinder. Background Technology
[0002] Electric cylinders are products specifically designed for continuous motion, low to high loads, and multiple cycles within their service life. These products have extremely high positioning accuracy and controllability. Electric cylinders are generally driven by a motor, which then pushes the piston rod horizontally through a thread. To prevent the piston rod from rotating, an anti-rotation guide structure is usually installed. Currently, the anti-rotation performance of existing electric cylinder anti-rotation guide structures is limited, and the piston rod is easily damaged when subjected to large external forces, which has certain shortcomings. Utility Model Content

A sliding groove is provided at the front end of the cylinder body, a fixed tube is provided on the left side of the cylinder body, a limit block is provided on the inner wall of the fixed tube, the piston rod is provided on the cylinder body, a limit groove is provided at the top end of the piston rod, the right side of the mounting plate is provided on the piston rod, a threaded groove is provided on the right side of the mounting plate, and the mounting plate is threadedly connected to the round rod through the threaded groove.
[0005] Preferably, two slots are symmetrically provided on the left side of the cylinder body, and the inner walls of the two slots are provided with round holes.
[0006] Preferably, there are two limiting grooves, and the two limiting grooves are slidably connected to the corresponding limiting blocks.
[0007] Preferably, there are two threaded grooves and two round rods, and the two round rods are slidably connected to the corresponding grooves.
[0008] Preferably, it further includes a buffer assembly, which includes a retaining ring that is locked in the slot, a spring disposed on the left side of the retaining ring, a retaining ring disposed on the left side of the spring, and a buffer pad bonded to the left side of the retaining ring.
[0009] Preferably, the buffer assembly further includes a stud disposed on the right side of the retaining ring and a nut threadedly connected to the stud.
[0010] Preferably, there are two buffer components, which are symmetrically distributed on the cylinder body.
[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: the cooperation between the limiting groove and the limiting block in this utility model allows the piston rod to move only horizontally and linearly, which plays a good role in preventing rotation and guiding. The cooperation between the round rod and the sliding groove also allows the piston rod to move only horizontally and linearly, which greatly improves the anti-rotation and guiding effect of the electric cylinder and can withstand greater external forces. At the same time, the round rod can be rotated and disassembled for replacement and maintenance. The spring of the buffer component provides a certain buffering effect for the retaining ring, which can prevent the mounting plate from hitting the cylinder body. The buffer pad can further buffer. At the same time, the nut can be rotated and can be disengaged from the stud after rotation for replacement of the buffer component. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0022] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing an anti-rotation guide structure for an electric cylinder.
[0023] Example 1:
[0024] Reference Figure 1-3This is the first embodiment of the present invention, which provides an anti-rotation guide structure for an electric cylinder, including a cylinder body 100, a piston rod 200 and a mounting plate 300.
[0025] Specifically, a sliding groove 110 is provided at the front end of the cylinder body 100, and a fixed tube 120 is provided on the left side of the cylinder body 100. A limit block 121 is provided on the inner wall of the fixed tube 120. In actual use, the limit block 121 can cooperate with the limit groove 210 to achieve a good guiding and anti-rotation effect.
[0026] Furthermore, two slots 130 are symmetrically provided on the left side of the cylinder body 100. The inner walls of the two slots 130 are provided with round holes 131. In actual use, the slots 130 and round holes 131 facilitate the fixing of the buffer assembly 400.
[0027] Specifically, the piston rod 200 is mounted on the cylinder body 100, and a limiting groove 210 is provided at the top of the piston rod 200. In actual use, the limiting groove 210 is used in conjunction with the limiting block 121.
[0028] Furthermore, there are two limiting grooves 210, and the two limiting grooves 210 are slidably connected to the corresponding limiting blocks 121.
[0029] Specifically, the right side of the mounting plate 300 is mounted on the piston rod 200. A threaded groove 320 is provided on the right side of the mounting plate 300. The mounting plate 300 is threadedly connected to the round rod 310 through the threaded groove 320. In actual use, the round rod 310 can be fixed on the mounting plate 300 through the threaded groove 320 for replacement and maintenance of the round rod 310.
[0030] Furthermore, there are two threaded grooves 320 and two round rods 310. The two round rods 310 are slidably connected to the corresponding sliding grooves 110. The cooperation between the two round rods 310 and the sliding grooves 110 can greatly improve the guiding and anti-rotation effect and the stability.
[0031] Example 2:
[0032] Reference Figure 1 and Figure 4 This is the second embodiment of the present invention, which differs from the first embodiment in that it also includes a buffer assembly 400. The buffer assembly 400 includes a fixing ring 410 that is locked in the slot 130, a spring 420 disposed on the left side of the fixing ring 410, a retaining ring 430 disposed on the left side of the spring 420, and a buffer pad 440 bonded to the left side of the retaining ring 430. In actual use, the elasticity of the spring 420 gives the retaining ring 430 a certain buffering effect, which can buffer the mounting plate 300 and prevent the mounting plate 300 from hitting the cylinder body 100, while the buffer pad 440 can further buffer.
[0033] Furthermore, the buffer assembly 400 also includes a stud 450 disposed on the right side of the retaining ring 410 and a nut 460 threadedly connected to the stud 450. In actual use, the engagement of the stud 450 and the nut 460 can fix the buffer assembly 400 on the cylinder 100 for replacement.
[0034] Furthermore, there are two buffer components 400, which are symmetrically distributed on the cylinder block 100.
[0035] The working principle and usage process of this utility model are as follows: During use, due to the guidance of the limiting block 121 of the fixed tube 120, the piston rod 200 can only move horizontally and linearly, which plays a good role in preventing rotation and guiding. Then, due to the presence of the sliding groove 110, the piston rod 200, the mounting plate 300 and the round rod 310 can only move horizontally and linearly, which greatly improves the anti-rotation and guiding effect of the electric cylinder, can withstand greater external forces, and has a long service life. At the same time, the two round rods 310 can be rotated until they are completely separated from the mounting plate 300 for replacement and maintenance. When the mounting plate 300 contacts the buffer assembly 400, due to the presence of the spring 420, the retaining ring 430 can buffer the mounting plate 300, effectively preventing the mounting plate 300 from hitting the cylinder body 100. The buffer pad 440 can further buffer, preventing the mounting plate 300 from hitting the retaining ring 430. At the same time, the nut 460 can be rotated until it is completely separated from the stud 450 for replacement of the buffer assembly 400.
[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
