Description

Technical Field

[0001] This utility model relates to the field of actuator technology, and more specifically, to a high-load actuator bearing structure. Background Technology

[0002] An actuator, as an actuating element that converts energy into controllable linear or rotary mechanical motion, is a core component in modern mechanical equipment that transmits power and achieves precise actions. Especially in high-load applications, such as lifting large equipment, precision positioning of heavy-duty workpieces, or fatigue testing of high-stress structures, the actuator support structure typically consists of the actuator body and its mounting base. Its main functions are to provide a robust support connection, precisely constrain the position of the actuator, and safely distribute and transmit its working load.

[0003] However, traditional actuator support structures often suffer from significant compatibility issues. Most existing mounting structures use rigid fixing or preset-sized limit blocks to constrain the end plate, making it difficult to adapt to changes in the size and specifications of the end plate of different actuator models. When replacing actuators of different specifications, it is usually necessary to replace or re-customize the mounting components, which increases the cost of use and downtime.

[0004] In view of this, we propose a high-load actuator bearing structure. Utility Model Content

[0005] Technical problems to be solved The purpose of this invention is to provide a high-load actuator bearing structure to solve the problem of poor adaptability of traditional high-load actuator bearing structures mentioned in the background art.

[0006] Technical solution A high-load actuator support structure includes an actuator body and a mounting base. A first clamping plate is fixedly connected to the mounting base. A second clamping plate is elastically connected to the top of the first clamping plate via a spring. Clamping assemblies are fixedly connected to the opposite surfaces of the first and second clamping plates. The clamping assemblies are used to clamp the end plate of the actuator body to limit the actuator.

[0007] Preferably, the clamping assembly includes a first limiting block and a second limiting block arranged in an L-shape, and a limiting plate is slidably arranged on the other side of the first limiting block and the second limiting block. The first limiting block and the second limiting block are used to limit the end plate in the length direction of the end plate, and the limiting plate is used to cooperate with the first limiting block and the second limiting block to limit the end plate in the width direction of the end plate.

[0008] Preferably, the bottom of both the first limiting block and the second limiting block are fixedly connected to sliders, and both the first clamping plate and the second clamping plate are provided with grooves for the sliders to slide.

[0009] Preferably, the clamping assembly further includes a bidirectional screw for driving the first clamping plate and the second clamping plate closer to or further away from each other, and a motor for driving the bidirectional screw to rotate.

[0010] Preferably, the threads at both ends of the bidirectional screw are arranged in opposite directions, and both ends of the bidirectional screw are connected to a threaded sleeve through a ball screw pair thread, and the two threaded sleeves are respectively fixedly connected to the first limiting block and the second limiting block.

[0011] Preferably, the clamping assembly further includes an electric push rod fixedly connected to the first clamping plate and the second clamping plate, the extended end of the electric push rod being fixedly connected to the limiting plate.

[0012] Preferably, the distance between the first clamping plate and the second clamping plate in the initial state is less than the height of the end plate of the actuator body that they will support.

[0013] Beneficial effects Compared with existing technologies, the advantages of this utility model are: This invention utilizes a spring between the first and second clamping plates to effectively absorb impact energy and provide a buffering effect when the device is subjected to impact loads or high-frequency vibrations. This reduces the risk of damage to the device caused by stress concentration due to rigid connections, protects the actuator body end plate, connecting bolts, and the entire load-bearing structure, thereby significantly improving the system's operational stability under high load conditions.

[0014] The adjustable clamping assembly of this invention can precisely and flexibly adjust the relative positions between the first limiting block, the second limiting block, and the limiting plate. This allows the bearing structure to adapt to actuator end plates of different heights and widths. When changing the actuator model, the clamping size can be quickly changed and the new end plate can be accurately fixed simply by driving the adjustment mechanism through a motor or control system. This significantly improves the versatility and maintenance efficiency of the equipment and reduces the cost of use.

[0015] The design of this utility model, in which the initial distance between the first clamping plate and the second clamping plate is less than the height of the end plate, ensures that the spring is in a compressed state when the actuator body is not installed. When the actuator end plate is placed between the two clamping components, the compression force of the spring will apply a continuous and adaptive clamping force to the end plate through the second clamping plate and the clamping components. This setting effectively eliminates the installation gap and avoids the impact, shaking and noise that may occur when the equipment starts, stops or changes the load direction.

[0019] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-4 This utility model provides a technical solution: A high-load actuator support structure includes an actuator body 1 and a mounting base 102. A first clamping plate 103 is fixedly connected to the mounting base 102. A second clamping plate 104 is elastically connected to the top of the first clamping plate 103 via a spring 105. Clamping components 2 are fixedly connected to the opposite surfaces of the first clamping plate 103 and the second clamping plate 104. The clamping components 2 are used to clamp the end plate 101 of the actuator body 1 to limit the actuator. This configuration gives the entire support structure elasticity and buffering capacity, enabling it to effectively absorb vibration and impact energy under high load or impact conditions, protect the actuator body 1 and its connecting structure, and improve system reliability and lifespan.

[0022] Specifically, the clamping assembly 2 includes a first limiting block 23 and a second limiting block 24 arranged in an L-shape. A limiting plate 22 is slidably arranged on the other side of the first limiting block 23 and the second limiting block 24. The first limiting block 23 and the second limiting block 24 are used to limit the end plate 101 in the length direction. The limiting plate 22 is used to cooperate with the first limiting block 23 and the second limiting block 24 to limit the end plate 101 in the width direction. In this way, the L-shaped first limiting block 23 and the second limiting block 24 form a positioning surface along the length direction of the end plate 101, which effectively restricts the movement of the end plate 101 in the length direction. The slidable limiting plate 22 can closely fit the side of the end plate 101, which restricts its movement in the width direction. This achieves efficient and reliable limiting of the end plate 101 in multiple directions in the horizontal plane.

[0023] Furthermore, the bottom of the first limiting block 23 and the second limiting block 24 are both fixedly connected to sliders 25, and the first clamping plate 103 and the second clamping plate 104 are both provided with grooves 26 for sliding of sliders 25. With this arrangement, the cooperation between sliders 25 and grooves 26 provides precise movement guidance for the first limiting block 23 and the second limiting block 24, ensuring that they always maintain parallel movement during the adjustment process and will not be skewed, thus ensuring the stability of the adjustment.

[0024] Secondly, the clamping assembly 2 also includes a bidirectional screw 27 for driving the first clamping plate 103 and the second clamping plate 104 to move closer or further apart from each other, and a motor 29 for driving the bidirectional screw 27 to rotate. This configuration automates the adjustment of the spacing of the clamping assembly 2 through the combination of the bidirectional screw 27 and the motor 29, eliminating the tediousness of manual adjustment. The first limit block 23 and the second limit block 24 can be quickly adapted to end plates 101 of different widths simply by controlling the system, thereby improving the operating efficiency and versatility of the equipment.

[0025] Furthermore, the threads at both ends of the bidirectional screw 27 are reversed, and both ends of the bidirectional screw 27 are connected to a threaded sleeve 28 via a ball screw thread. The two threaded sleeves 28 are fixedly connected to the first limiting block 23 and the second limiting block 24, respectively. This configuration allows for precise control of the extension and retraction position of the limiting plate 22, thereby firmly pressing or releasing the end plate 101 in the width direction, improving the convenience of operation during adjustment. This configuration also ensures the symmetry of the clamping assembly 2 during the adjustment process, making the force more uniform and stable.

[0026] In addition, the clamping assembly 2 also includes an electric push rod 21 fixedly connected to the first clamping plate 103 and the second clamping plate 104. The extended end of the electric push rod 21 is fixedly connected to the limiting plate 22. This configuration allows for precise control of the extension and retraction position of the limiting plate 22, thereby firmly pressing or releasing the end plate 101 in the width direction and improving the convenience of operation during adjustment.

[0027] Furthermore, the initial distance between the first clamping plate 103 and the second clamping plate 104 is less than the height of the end plate 101 of the actuator body 1 that they will support. This arrangement ensures that the spring 105 is in a certain pre-compressed state before the end plate 101 is installed. When the end plate 101 is installed, the two limiting plates 22 need to be opened. The strong restoring force generated by the spring 105 after being further compressed will continuously apply a pre-tightening force to the end plate 101 through the second clamping plate 104 and the clamping assembly 2. This can prevent the equipment from shaking and making noise when starting, reversing or being impacted, and always ensure that the end plate 101 is firmly pressed, with good connection rigidity and efficient and accurate power transmission.

[0028] Working principle: When installing the actuator, the motor 29 first drives the bidirectional screw 27 to rotate. Through the reverse thread and ball screw pair, the first limiting block 23 and the second limiting block 24 of the clamping components 2 on both sides move away or closer to each other along the slide groove 26, adjusting their distance to match the width of the end plate 101. Then, the actuator end plate 101 is placed between the clamping components 2 on both sides, and the electric push rod 21 is controlled to push the limiting plate 22 to press the end plate 101 from the width direction. At the same time, since the distance between the first and second clamping plates 104 in the initial state is less than the height of the end plate 101, when the end plate 101 is inserted, the second clamping plate 104 will compress the spring 105 and be slightly pushed open. The continuous restoring force generated by the spring 105 applies an adaptive preload to the end plate 101 through the clamping components 2. Combined with the rigid limiting of the clamping components 2, the actuator end plate 101 is firmly clamped, and a buffer can be provided under high load or impact.
