Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a quick clamping device for an electromagnetic pilot valve. Background Art

[0002] An electromagnetic pilot valve is a valve controlled by electromagnetic force, mainly used in hydraulic and pneumatic systems. By changing the current in the electromagnetic coil, it controls the opening and closing of the valve. A quick clamping device can make the installation process of the electromagnetic pilot valve faster, which is particularly important for an automated production line or occasions where equipment needs to be frequently replaced.

[0003] Currently, the commonly used quick clamping device for electromagnetic pilot valves usually has electromagnetic pilot valves evenly installed on the mounting plate. The liquid return port of the mounting plate is interconnected with the liquid inlet rubber hose, and the liquid inlet is interconnected with the liquid return rubber hose. The first through hole on the mounting plate is interconnected with the second through hole at the bottom of the electromagnetic pilot valve. Both sides of the mounting plate are connected to the bridge plate through connecting plates, and the connection of the bridge plate is connected to the electromagnetic pilot valve through bolts, avoiding the sealing failure and damage of the main valve spool of the electromagnetic pilot valve, effectively reducing the assembly and clamping processes and improving the assembly stability.

[0004] However, when using this method, the height of the mounting plate cannot be adjusted. If the height of the mounting plate does not match the installation position, it will lead to difficult installation or inability to install, requiring additional adapter parts or adjusting the workbench, increasing the installation cost and time. The inability to quickly adjust the height of the mounting plate means that the workbench or other equipment needs to be readjusted every time the electromagnetic pilot valve is replaced, which increases the installation and replacement time and reduces the work efficiency. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a quick clamping device for an electromagnetic pilot valve, aiming to improve the problem that the existing quick clamping device for an electromagnetic pilot valve cannot adjust the height of the mounting plate.

[0006] To achieve the above object, the utility model provides the following technical solution: A quick clamping device for an electromagnetic pilot valve, including a bottom plate and a mounting plate. A cylinder is fixedly connected to the right part of the bottom plate. The output end of the cylinder is fixedly connected with a push block.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1 - 3, an embodiment provided by the present utility model: a quick clamping device for an electromagnetic pilot valve, including a bottom plate 1 and a mounting plate 14. A cylinder 2 is fixedly connected to the right part of the bottom plate 1. The output end of the cylinder 2 is fixedly connected to a push block 3. Connecting rods 4 are fixedly connected to both sides of the push block 3. Limiting components are fixedly connected to both ends of the connecting rods 4. The limiting components are used to limit the connecting rods 4. Rotatingly connected to the outside of both connecting rods 4 are first movable support rods 8. Rotatingly connected to the inside of the first movable support rods 8 is a second movable support rod 9. Rotatingly connected to the inside of the second movable support rod 9 is a pulley 16. Fixed seats 15 are fixedly connected to both sides of the bottom of the mounting plate 14. Both pulleys 16 are slidably connected to the inside of the fixed seats 15. The limiting component includes a slider 5. The slider 5 is fixedly connected to the end of the connecting rod 4 away from the push block 3. The slider 5 is slidably connected to the outside of a slide rod 6. Fixed seats 12 are fixedly connected to both sides of the upper part of the bottom plate 1. Slide rods 6 are fixedly connected to the inside of both fixed seats 12. Compression springs 7 are sleeved on the outside of both slide rods 6. One end of the compression spring 7 is fixedly connected to the inside of the fixed seat 12. The other end of the compression spring 7 is fixedly connected to the slider 5. Fixed blocks 10 are fixedly connected to both sides of the upper part of the bottom plate 1. A first hinge block 11 is fixedly connected to the upper part of the fixed block 10. The second movable support rod 9 is rotatably connected to the inside of the first hinge block 11. Second hinge blocks 13 are fixedly connected to both sides of the bottom of the mounting plate 14. The first movable support rod 8 is rotatably connected to the inside of the second hinge block 13.

[0024] In the case where the height of the mounting plate 14 needs to be finely adjusted, the operator will activate the cylinder 2, the core component of this pneumatic device. With the activation of the cylinder 2, its powerful output end will exert force to push the push block 3. After the push block 3 is pushed, it will start to move. During this process, it will drive the connecting rod 4 to move accordingly. The connecting rod 4 is responsible for converting the movement of the push block 3 into the power for the smooth sliding of the slider 5 on the outside of the slide rod 6. When the slider 5 slides along the outside of the slide rod 6, it exerts pressure on the compression spring 7. The compression spring 7, as an elastic element, plays a crucial buffering role in this process, ensuring that any impact or vibration generated during the height adjustment of the mounting plate 14 is effectively absorbed, thereby protecting the entire mechanical structure from damage. The movement of the connecting rod 4 is not limited to pushing the slider 5. It is also responsible for driving the first movable support rod 8 to move. The first movable support rod 8 is a support rod that can move in two directions. During its movement, it will drive the second movable support rod 9 to rotate inside the first hinge block 11. This precise rotation mechanism enables the second movable support rod 9 to rotate around the inside of the second hinge block 13, thereby driving the pulley 16 to slide smoothly inside the fixed seat 15. Thanks to the coordinated action of the first movable support rod 8 and the second movable support rod 9, the mounting plate 14 can achieve precise up and down movement.

[0025] Refer to Figure 1, a fixing frame 17 is fixedly connected to the upper part of the mounting plate 14. Hydraulic cylinders 19 are fixedly connected to the upper parts of the fixing frame 17. The output ends of the hydraulic cylinders 19 are fixedly connected to an upper fixing frame 22. Lower fixing frames 18 are fixedly connected to the upper parts of the mounting plate 14. Limit columns 20 are fixedly connected to both sides of the upper part of the upper fixing frame 22. The limit columns 20 are slidably connected to the inside of the fixing frame 17. Return springs 21 are sleeved on the outside of multiple limit columns 20. An anti-slip pad 23 is arranged at the bottom of the upper fixing frame 22. A buffer pad 24 is arranged at the upper part of the lower fixing frame 18. One end of the return spring 21 is fixedly connected to the bottom of the fixing frame 17, and the other end of the return spring 21 is fixedly connected to the upper part of the upper fixing frame 22.

[0026] When performing the installation operation of the electromagnetic pilot valve, first, the electromagnetic pilot valve needs to be accurately placed above the lower fixing frame 18. Then, start the operating mechanism of the hydraulic cylinder 19. The hydraulic cylinder 19 pushes the upper fixing frame 22 downward through its output end. As the upper fixing frame 22 moves, the limit columns 20 also move accordingly. This process simultaneously has a stretching effect on the return spring 21. The stretching effect enables the upper fixing frame 22 to move downward smoothly, thereby fixing the electromagnetic pilot valve. By this method, the electromagnetic pilot valve can be quickly and firmly clamped and fixed, greatly improving the assembly efficiency. The function of the anti-slip pad 23 is to provide good anti-slip function during use, ensuring that the upper fixing frame 22 can be firmly fixed in the predetermined position and avoiding displacement caused by insufficient friction. The main function of the buffer pad 24 is to play a role in shock absorption and buffering. When an impact force acts on the lower fixing frame 18, the buffer pad 24 can effectively absorb these forces, reduce the impact on the equipment, and protect the equipment from damage.

[0027] Working principle: When it is necessary to adjust the height of the mounting plate 14, the cylinder 2 is started. The output end of the cylinder 2 pushes the push block 3 to move. When the push block 3 moves, it drives the connecting rod 4 to move. When the connecting rod 4 moves, it drives the slider 5 to slide outside the sliding rod 6. When the slider 5 slides, it squeezes the compression spring 7, and the compression spring 7 plays a certain buffering role. When the connecting rod 4 moves, it drives the first movable support rod 8 to move. The first movable support rod 8 drives the second movable support rod 9 to rotate inside the first hinge block 11. When the first movable support rod 8 moves, it rotates inside the second hinge block 13. The rotation of the second movable support rod 9 drives the pulley 16 to slide inside the positioning seat 15. Under the action of the first movable support rod 8 and the second movable support rod 9, the mounting plate 14 moves up and down, realizing convenient adjustment of the height of the mounting plate 14. The height of the mounting plate 14 can be quickly adjusted according to needs to match the installation position, simplifying the installation process and improving the efficiency of replacing and repairing the electromagnetic pilot valve. When it is necessary to install the electromagnetic pilot valve, place the electromagnetic pilot valve on the upper part of the lower fixing frame 18, start the hydraulic cylinder 19, and the output end of the hydraulic cylinder 19 pushes the upper fixing frame 22 to move downward. When the upper fixing frame 22 moves, it drives the limit post 20 to move. During the movement of the upper fixing frame 22, the return spring 21 is stretched, so that the upper fixing frame 22 moves downward to fix the electromagnetic pilot valve, realizing quick clamping and fixing of the electromagnetic pilot valve, which can greatly reduce the assembly time, quickly complete the installation of the electromagnetic pilot valve, and reduce the operation difficulty.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
