Description

Technical Field

[0001] This utility model relates to the field of control equipment technology, and in particular to a servo valve control device. Background Technology

[0002] Servo valve controllers are core devices in industrial automation used for precise control of servo valves. Their primary function is to receive command signals from a PLC (Programmable Logic Controller) and convert them into current or voltage signals adapted to the servo valve, thereby achieving high-precision control of hydraulic or pneumatic systems. They are typically installed near the servo valve and connected to it via electrical wiring. They also communicate with the PLC in real-time using industrial Ethernet, fieldbus (such as EtherCAT, Profinet, CANopen, etc.), or analog / digital interfaces, forming a complete closed-loop control system. Widely used in industrial automation and hydraulic control systems, their stability and reliability directly impact equipment operational safety.

[0003] The inventors have discovered at least the following problems in the prior art:

[0004] The wiring terminals of existing servo valve controllers are usually exposed to the external environment. Long-term use can easily lead to poor contact, short circuit or signal interference due to dust accumulation. This problem is particularly prominent in high dust industrial scenarios (such as metallurgy and mining). Although traditional dust prevention measures (such as sealing rings and protective sleeves) can partially prevent dust, they have problems such as loose structure, easy aging and deformation, and affect heat dissipation efficiency.

[0005] In addition, after the controller is wired, the cables are often in a disordered state, with different functional lines (such as power lines and signal lines) tangled together, resulting in uneven heat dissipation and increasing the difficulty of troubleshooting during maintenance. Although some cables are fixed with cable ties, the lack of group support for the cables cannot solve the fundamental problem.

[0006] Therefore, this solution provides a servo valve control device to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a servo valve control device to solve the problems of insufficient dustproof performance of the wiring terminals and uneven heat dissipation caused by disordered connecting wires in the prior art.

[0008] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0009] A servo valve control device includes a controller body installed inside a frame. One end of the controller body has a connector plug, and the other end has a guide mechanism and a protective mechanism. The guide mechanism includes an upper crossbeam and a lower crossbeam distributed vertically, and side guide rails fixedly connected to both ends of the upper and lower crossbeams. Three faceted abutments are provided on one side of the lower crossbeam. The protective mechanism includes a protective groove and three L-shaped plates inside the protective groove. A cable management notch is provided on one side of the protective groove, and an L-shaped embedding groove is provided on one side wall of the cable management notch. The L-shaped plates are slidably connected to the inside of the L-shaped embedding groove, and uniformly arranged ratchet blocks are fixedly connected to one side of the L-shaped plates.

[0010] Preferably, a limiting block is fixedly connected to the outer side of the side guide rail, and a limiting groove is opened on the inner side wall of the protective groove corresponding to the side guide rail. The limiting groove fits the limiting block, and the upper and lower crossbars are both connected to one end of the controller body by bolts.

[0011] Preferably, the lower crossbar is internally connected to a receiving slider that slides up and down, and the cut-face blocks are all fixedly connected to one side of the receiving slider.

[0012] Preferably, a pull rod is fixedly connected below the receiving slider, the pull rod passes through the bottom of the lower crossbar, and uniformly distributed elastic elements are fixedly connected below the receiving slider.

[0013] Preferably, a snap-fit ​​groove is provided at the bottom of the protective groove adjacent to the cable management notch, the snap-fit ​​groove fits the cut surface abutment, and the top of the cut surface abutment fits one side of the L-shaped plate.

[0014] Preferably, the L-shaped embedding groove is fixedly connected with uniformly arranged limiting rods, one end of which penetrates the L-shaped plate.

[0015] Preferably, the L-shaped plate is fixedly connected to one side inside the L-shaped embedding groove with evenly distributed tension springs.

[0016] The beneficial effects of this utility model are:

[0017] I. This utility model, through the cooperation of the guide mechanism and the protective mechanism, the snap-fit ​​groove at the bottom of the protective groove cooperates with the cut surface block of the lower cross frame, pushing the L-shaped plate to slide outward and extend the ratchet block, forming a physical barrier to the outside of the connector plug, preventing dust from directly contacting the sensitive components; at the same time, when the L-shaped plate is attached to the inner wall of the protective groove, it can block the dust above from falling, reducing the risk of poor contact caused by dust accumulation in high dust environments.

[0018] II. Through the cooperation of the guide mechanism and the protective mechanism, the L-shaped plate extends outward and the ratchet block on it can lift different functional cables to the height when connected after deformation, so as to achieve group support and isolation. This not only avoids local overheating caused by cable entanglement, but also facilitates quick location of faulty lines during maintenance. Attached Figure Description

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

[0030] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0031] This utility model provides a servo valve control device, including a controller body 1, which is installed inside a frame 2. One end of the controller body 1 is provided with a connector plug 11, and the other end of the controller body 1 is provided with a guide mechanism 3 and a protective mechanism 4.

[0032] The guide mechanism 3 includes an upper crossbeam 31 and a lower crossbeam 34 distributed vertically, and side guide rails 32 fixedly connected to both ends of the upper crossbeam 31 and the lower crossbeam 34. Three cut-faced abutments 35 are provided on one side of the lower crossbeam 34.

[0033] The protective mechanism 4 includes a protective groove 41 and three L-shaped plates 45 inside the protective groove 41. A cable management notch 42 is provided on one side of the protective groove 41. An L-shaped embedding groove 43 is provided on one side wall of the cable management notch 42. The L-shaped plates 45 are slidably connected to the inside of the L-shaped embedding groove 43. A uniformly arranged ratchet block 48 is fixedly connected to one side of the L-shaped plate 45.

[0034] The main controller unit 1 is a servo valve controller, brand Rexroth.

[0035] The model number is: SYHNC100-NIB-23 / W-24-PD-E23-A012;

[0036] The connector 11 is a terminal for connecting an external power supply, PLC, and servo valve top via a cable; the upper and lower ends of the inner wall of the protective groove 41 fit the outer periphery of the upper crossbar 31 and the lower crossbar 34, and are equipped with sealing gaskets.

[0037] In a further embodiment, a limiting block 33 is fixedly connected to the outer side of the side guide rail 32, and a limiting groove 49 is opened on the inner side wall of the protective groove 41 corresponding to the side guide rail 32. The limiting groove 49 fits the limiting block 33, and the upper crossbeam 31 and the lower crossbeam 34 are both connected to one end of the controller body 1 by bolts.

[0038] In this embodiment, the limiting block 33 is used to limit the vertical sliding range of the entire protective mechanism 4.

[0039] In a further embodiment, a receiving slider 36 is slidably connected to the inside of the lower crossbar 34, and the cut surface blocks 35 are all fixedly connected to one side of the receiving slider 36.

[0040] In this embodiment, the lower crossbar 34 has a groove inside for the receiving slider 36 to slide up and down, and the outer side wall of the lower crossbar 34 has a sliding groove, which is used to facilitate the connection and sliding of the cut surface block 35 and the receiving slider 36 through the connecting block.

[0041] In a further embodiment, a pull rod 38 is fixedly connected below the receiving slider 36, the pull rod 38 penetrates the bottom of the lower crossbar 34, and elastic members 37 are evenly distributed below the receiving slider 36.

[0042] In this embodiment, when the pull rod 38 is pulled down, it can drive the receiving slider 36 to move down, thereby releasing the pressure of the cut surface block 35 on the L-shaped plate 45. Then, under the pulling action of the tension spring 47, the L-shaped plate 45 can retract back into the L-shaped embedding groove 43. However, the ratchet block 48 is still inside the cable management notch 42, which makes it easy to release the group support of the cable so that the entire protective mechanism 4 can be lifted up again.

[0043] In a further embodiment, a snap-fit ​​groove 44 is provided at the bottom of the protective groove 41 adjacent to the cable management notch 42. The snap-fit ​​groove 44 fits into the cut surface abutment 35, and the top of the cut surface abutment 35 fits into one side of the L-shaped plate 45.

[0044] In this embodiment, the snap-fit ​​groove 44 allows the cut-faced abutment block 35 to be fully embedded, thereby allowing one end of the cut-faced abutment block 35 to push open the L-shaped plate 45, causing the L-shaped plate 45 to be displaced.

[0045] In a further embodiment, a set of evenly distributed limiting rods 46 are fixedly connected inside the L-shaped embedding groove 43, with one end of the limiting rod 46 penetrating through the L-shaped plate 45.

[0046] In this embodiment, the limiting rod 46 is used to limit the extension and retraction distance of the L-shaped plate 45, while the tension spring 47 is always pulling the L-shaped plate 45.

[0047] In a further embodiment, the L-shaped plate 45 is fixedly connected to one side inside the L-shaped embedding groove 43 with evenly distributed tension springs 47.

[0048] In this embodiment, the ratchet block 48 can be attached to the inner wall of the cable management notch 42 after the L-shaped plate 45 extends out, and the plastic of the ratchet block 48 can be deformed, so that the cable can be lifted up after being pulled down and located in the cable management notch 42 and above the ratchet block 48.

[0049] The working principle of this utility model is as follows:

[0050] After the front end of the controller body 1 is connected to the servo valve and the PLC controller respectively via cables, the protective groove 41 can be pulled down directly until the bottom of the protective groove 41 is flush with the bottom of the lower crossbar 34. During this process, the cut-face block 35 will passively enter the interior of the snap-fit ​​groove 44 and push the L-shaped plate 45 outward, thereby allowing the L-shaped plate 45 to slide out from the interior of the L-shaped embedded groove 43, and allowing the ratchet block 48 to stick to the other side wall of the cable management notch 42. At this time, the cable can be lifted up along the lower notch of the cable management notch 42. During the lifting process, the ratchet block 48 will be pushed to deform until the cable moves to the same height or approximately the same height as the connecting plug 11. Then, the cable will be stopped from being lifted up. At this time, the cable will be supported by the ratchet block 48. After the connected cables are all lifted to the corresponding height, the ratchet block 48 can provide support and can also group the cables for cable management. Therefore, it can not only provide support for the connected cables to avoid bending at the connection point and reduce the life, but also increase the spacing between the cables by grouping the cables, thereby improving the heat dissipation efficiency.

[0051] After the bottom of the protective groove 41 is flush with the bottom of the lower crossbar 34, the L-shaped plate 45 extends out, thereby protecting the outer perimeter of the front end of the controller body 1 where the connector plug 11 is located. This not only prevents dust from falling onto the connector plug 11, but also provides protection against collisions that could damage the connector plug 11.

[0052] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
