Description

Technical Field

[0001] This utility model relates to the technical field of servo hydraulic cylinder support devices, specifically a stable support mechanism for servo hydraulic cylinders. Background Technology

[0002] Servo hydraulic cylinders, as high-precision power actuators, are widely used in heavy or high-precision fields such as industrial automation, engineering machinery, and metallurgical equipment. The stability of their working performance directly affects the machining accuracy, smooth operation, and reliability of the entire equipment system.

[0003] In practical applications, servo hydraulic cylinders generate vibrations of varying degrees when starting, reversing, or bearing load impacts. These vibrations mainly originate from pressure pulsations in the hydraulic system, the inertial force of the piston rod during start-up and shutdown, and instantaneous changes in external loads. Existing servo hydraulic cylinders are typically rigidly mounted directly on the equipment base via flanges, lugs, or other connecting components. This rigid connection method causes the vibrations generated by the hydraulic cylinder to be transmitted to the main frame with almost no attenuation, resulting in resonance and noise throughout the equipment. This not only affects the normal operation of adjacent precision components but can also lead to structural fatigue or even damage in the long term. At the same time, the impact and vibration of external loads are also transmitted back to the hydraulic cylinder through the base, affecting the detection accuracy and control stability of its internal precision sensors. Utility Model Content

[0004] The purpose of this invention is to provide a stable support mechanism for a servo hydraulic cylinder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stabilizing support mechanism for a servo hydraulic cylinder, comprising: a base and a mounting plate; The damping mechanism includes two first sliding grooves symmetrically opened on the upper end of the base. Two sliders are symmetrically slidably connected to the inner walls of the two first sliding grooves. A connecting rod is rotatably connected to the side wall of each slider. The other end of the connecting rod is rotatably connected to the side wall of the mounting plate. A first sliding rod is fixedly connected to the inner wall of the first sliding groove. The side wall of the first sliding rod is slidably connected to the slider. Two first damping spring dampers are symmetrically sleeved on the side wall of the first sliding rod. The two ends of the damping spring dampers are fixedly connected to the inner wall of the first sliding groove and the side wall of the slider, respectively.

[0006] Preferably, the upper end of the mounting plate is provided with a second sliding groove, and a mounting base is slidably connected to the inner wall of the second sliding groove.

[0007] Preferably, the upper end of the mounting base is provided with a mounting groove for mounting a servo hydraulic cylinder.

[0008] Preferably, the damping mechanism further includes a second slide rod fixedly connected to the inner wall of the second slide groove, the side wall of the second slide rod being slidably connected to the mounting base, and two second damping spring dampers being symmetrically sleeved on the side wall of the second slide rod, with both ends of the second damping spring dampers being fixedly connected to the inner wall of the second slide groove and the side wall of the mounting base, respectively.

[0009] Preferably, two fixed plates are symmetrically slidably connected to the inner wall of the mounting groove, and a bidirectional screw is rotatably connected to the inner wall of the mounting groove. The side wall of the bidirectional screw is threadedly connected to the two fixed plates, and one end of the bidirectional screw passes through the side wall of the mounting base and is fixedly connected to a handle.

[0010] Preferably, the mounting groove is T-shaped.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) The stabilizing support mechanism for the servo hydraulic cylinder, by setting a damping mechanism, in the vertical direction, through the symmetrically arranged hinged connecting rod structure, converts the downward movement of the mounting plate into the opposite movement of the sliders on both sides, thereby compressing the first damping spring damper, effectively absorbing and dissipating vertical vibration energy. In the horizontal direction, through the sliding cooperation between the mounting seat and the second slide groove and the second damping spring damper, the axial vibration of the servo hydraulic cylinder is effectively suppressed. The bidirectional damping design in both vertical and horizontal directions can completely offset the multi-directional complex vibration generated when the servo hydraulic cylinder is working, significantly reducing the vibration transmitted to the main frame, protecting related equipment, and also reducing the impact of external vibration on the accuracy and life of the hydraulic cylinder itself.

[0012] (2) The servo hydraulic cylinder stable support mechanism, by setting a fixed plate and a two-way screw, and by using a T-shaped mounting groove and a fixed plate driven by the two-way screw, realizes the quick installation and fixing of the servo hydraulic cylinder. Simply put the hydraulic cylinder into the T-shaped groove and turn the lever to make the two fixed plates clamp the cylinder body synchronously. Compared with the traditional bolt fixing, this method saves time and effort, greatly simplifies the installation process, provides great convenience for the debugging, maintenance and replacement of the hydraulic cylinder, and improves the equipment maintenance efficiency.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a stabilizing support mechanism for a servo hydraulic cylinder, comprising: a base 1 and a mounting plate 2; The damping mechanism includes two first slide grooves 3 symmetrically opened on the upper end of the base 1. Two sliders 4 are symmetrically slidably connected to the inner walls of the two first slide grooves 3. A connecting rod 5 is rotatably connected to the side wall of each slider 4. The other end of the connecting rod 5 is rotatably connected to the side wall of the mounting plate 2. A first slide rod 6 is fixedly connected to the inner wall of the first slide groove 3. The side wall of the first slide rod 6 is slidably connected to the slider 4. Two first damping spring dampers 7 are symmetrically sleeved on the side wall of the first slide rod 6. The two ends of the damping spring dampers 7 are fixedly connected to the inner wall of the first slide groove 3 and the side wall of the slider 4, respectively.

[0017] The upper end of the mounting plate 2 is provided with a second sliding groove 8, and the inner wall of the second sliding groove 8 is slidably connected to the mounting base 9.

[0018] The upper end of the mounting base 9 has a mounting groove 10 for mounting a servo hydraulic cylinder, and the mounting groove 10 is T-shaped.

[0019] The damping mechanism also includes a second slide rod 11 fixedly connected to the inner wall of the second slide groove 8. The side wall of the second slide rod 11 is slidably connected to the mounting base 9. Two second damping spring dampers 12 are symmetrically sleeved on the side wall of the second slide rod 11. The two ends of the second damping spring dampers 12 are fixedly connected to the inner wall of the second slide groove 8 and the side wall of the mounting base 9, respectively.

[0020] Two fixed plates 13 are symmetrically slidably connected to the inner wall of the mounting groove 9. A bidirectional screw 14 is rotatably connected to the inner wall of the mounting groove 9. The side wall of the bidirectional screw 14 is threadedly connected to the two fixed plates 13, and one end of the bidirectional screw 14 passes through the side wall of the mounting base 9 and is fixedly connected to a handle.

[0021] In this invention, the servo hydraulic cylinder is placed in the mounting slot 9, and then the handle is turned to drive the bidirectional lead screw 14 to rotate, which in turn drives the two fixing plates 13 to move closer to each other, clamping and fixing the servo hydraulic cylinder, and quickly installing the servo hydraulic cylinder on the mounting base 9. Compared with the existing bolt fixing, the installation speed is faster and simpler.

[0022] When the servo hydraulic cylinder vibrates during use, the vibration causes the mounting plate 2 to move downwards. This, in turn, causes the two sliders 4 in the first slide groove 3 to slide away from each other via the two connecting rods 5. This, in turn, compresses the first damping spring damper 7. The extension and retraction of the first damping spring damper 7 converts the energy generated by the vibration into its elastic potential energy, thus effectively damping the servo hydraulic cylinder in the vertical direction. When the vibration causes the mounting base 9 to slide left and right in the second slide groove 8, it causes the second damping spring damper 12 to extend and retract, thereby damping the servo hydraulic cylinder in the horizontal direction. Therefore, the vibration of the servo hydraulic cylinder can be effectively reduced, thereby reducing damage during use and extending its service life.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
