Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and in particular to a safety protection component for electric actuators. Background Technology

[0002] A linear electric actuator is a device that converts electrical energy into linear motion. It is widely used in industrial automation, robotics, medical equipment, smart homes and other fields. It is driven by a motor and passes through a reduction gear and a transmission mechanism such as a lead screw or rack and pinion to achieve precise linear displacement control.

[0003] The existing announcement number is CN216719718U, entitled "A High-Efficiency Energy-Saving Transformer Voltage Stabilizer," which relates to the field of transformer auxiliary equipment technology. It includes a base plate with two connecting plates inside, and a voltage stabilizing coil between them. A brush is located at the upper end of the voltage stabilizing coil, and the lower end of the brush rests against the coil. A linear actuator is bolted to the upper ends of the two connecting plates. A controller is located on one side of the base plate, and a protective cover is located at the upper end. During use, the voltage stabilizing coil prevents overload power supply. When the input voltage fluctuates or becomes unbalanced, the coil stabilizes the voltage, ensuring the transformer's output voltage remains balanced and stable. This maintains the stability of the transformer's external output voltage and prevents alarms from the load equipment due to voltage problems. The voltage stabilizing component is designed to easily adjust changes in the transformer's internal voltage during operation.

[0004] However, when the push rod of the aforementioned linear electric actuator pushes the actuator mechanism to reciprocate, and the actuator mechanism on the mounting platform on the push rod undergoes left and right displacement switching, the inertia of the actuator mechanism itself will cause the push rod to move left and right, resulting in displacement exceeding the stroke path range. Since the electric actuator lacks an inertial buffer protection component, it is prone to misalignment due to inertia, which affects the accuracy of the electric actuator. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a safety protection component for electric actuators.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a safety protection component for an electric actuator, including a guide rod frame, a movable component, and a linear actuator body. The guide rod frame is horizontally fixed, and a movable component is horizontally slidably assembled on the guide rod frame. The movable component includes a movable platform, which is horizontally slidably assembled on the guide rod frame. A rod plate seat is provided below the movable platform. Horizontal crossbars are horizontally fixed on both sides of the top surface of the rod plate seat, and the crossbars of the rod plate seat are horizontally slidably connected to the bottom of the movable platform. A first spring is horizontally sleeved on the crossbar of the rod plate seat, and the other end of the first spring is fixed to the movable platform. A first damping rod is horizontally fixed in the middle of the top surface of the rod plate seat, and the other end of the first damping rod is fixed to the movable platform. The bottom surface of the rod plate seat is fixedly assembled with the push rod end of the linear actuator body.

[0007] As a preferred embodiment, a threaded tube is horizontally fixed at the bottom of the guide rod frame, and a screw is assembled in the threaded tube with horizontal threads.

[0008] As a preferred embodiment, a sleeve is horizontally fixed on the bottom surface of the rod plate seat, and the sleeve of the rod plate seat is fitted onto the push rod end of the linear actuator body, and the sleeve of the rod plate seat is fixedly assembled to the push rod end of the linear actuator body by locking bolts.

[0009] As a preferred embodiment, a hole block is horizontally fixed at the end of the linear actuator body, and a cylinder seat is provided on the bottom surface of the linear actuator body. A rod seat is horizontally provided below the cylinder seat, the rod seat is horizontally fixed, and the rod seat and the cylinder seat are horizontally slidably assembled.

[0010] As a preferred embodiment, a stud is vertically fixed on the top surface of the cylinder base, and the stud is provided through a hole block, with a nut threaded onto the top of the stud.

[0011] As a preferred embodiment, a second spring is horizontally sleeved on the rod seat, and the two ends of the second spring are fixed to the rod seat and the cylinder seat respectively.

[0012] As a preferred embodiment, a second damping rod is horizontally fixed on both sides of the inside of the rod seat, and the other end of the second damping rod is fixed on the cylinder seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the push rod of the linear actuator body pushes the moving table in the moving part to slide horizontally on the guide rod frame. The reciprocating motion of the push rod of the linear actuator body drives the moving table to slide horizontally back and forth on the guide rod frame. Then, the moving table bears the inertia generated when the path direction changes during the reciprocating motion of the actuator, causing the moving table to slide horizontally on the rod plate seat. The inertia of the moving table causes the deformation of the first spring to offset the inertia of the moving table. Then, the deformation potential energy of the first spring is offset by the restoring damping force of the first damping rod. Thus, the inertia generated when the moving table bears the reciprocating motion of the actuator and changes the path direction is absorbed and offset, avoiding the inertia generated when the moving table bears the reciprocating motion of the actuator and changing the path direction affecting the accuracy of the reciprocating motion of the push rod of the linear actuator body, and ensuring the accuracy of the electric actuator.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

[0026] like Figures 1 to 5As shown, a safety protection component for an electric actuator includes a guide rod frame 1, a movable component 2, and a linear actuator body 3. The guide rod frame 1 is horizontally fixed, and the movable component 2 is horizontally slidably mounted on the guide rod frame 1. The movable component 2 includes a movable platform 21, which is horizontally slidably mounted on the guide rod frame 1. A rod plate seat 22 is provided below the movable platform 21. Horizontal crossbars are horizontally fixed on both sides of the top surface of the rod plate seat 22, and the crossbars of the rod plate seat 22 are horizontally slidably connected to the bottom of the movable platform 21. A first spring 23 is horizontally sleeved on the crossbar of the rod plate seat 22, and the other end of the first spring 23 is fixed to the movable platform 21. A first damping rod 24 is horizontally fixed in the middle of the top surface of the rod plate seat 22, and the other end of the first damping rod 24 is fixed to the movable platform 21. The bottom surface of the rod plate seat 22 is fixedly assembled with the push rod end of the linear actuator body 3. During use, the linear actuator... The push rod of the actuator body 3 pushes the moving stage 21 in the moving part 2 to slide horizontally on the guide rod frame 1. The reciprocating motion of the push rod of the linear actuator body 3 drives the moving stage 21 to slide horizontally back and forth on the guide rod frame 1. Then, the moving stage 21 carries the inertia generated when the path direction changes during the reciprocating motion of the actuator, causing the moving stage 21 to slide horizontally on the rod plate seat 22. The inertia of the moving stage 21 causes the deformation of the first spring 23 to offset the inertia of the moving stage 21. Then, the deformation potential energy of the first spring 23 is offset by the restoring damping force of the first damping rod 24. Thus, the inertia generated when the moving stage 21 carries the actuator and changes the path direction during the reciprocating motion is absorbed and offset, avoiding the inertia generated when the moving stage 21 carries the actuator and changes the path direction from affecting the accuracy of the reciprocating motion of the push rod of the linear actuator body 3, and ensuring the accuracy of the electric actuator.

[0027] In one embodiment, such as Figure 2 and 5 As shown, a screw tube 11 is horizontally fixed at the bottom of the guide rod frame 1, and a screw rod 12 is assembled in the horizontal thread of the screw tube 11. In order to avoid the inertia generated when the moving table 21 carries the actuator and the path direction changes during reciprocating motion, which affects the accuracy of the reciprocating motion of the push rod of the linear actuator body 3, the screw rod 12 in the screw tube 11 is rotated out to press against the length of the push rod movement path of the linear actuator body 3, so as to avoid the push rod of the linear actuator body 3 from sliding out excessively due to inertia, thus protecting the accuracy of the linear actuator body 3.

[0028] In one embodiment, such as Figure 2 and 4As shown, a sleeve is horizontally fixed on the bottom surface of the rod plate seat 22, and the sleeve of the rod plate seat 22 is sleeved on the push rod end of the linear actuator body 3. The sleeve of the rod plate seat 22 is fixedly assembled to the push rod end of the linear actuator body 3 by locking bolts 25. During use, the sleeve on the bottom surface of the rod plate seat 22 is fixedly assembled to the push rod end of the linear actuator body 3 by locking bolts 25, which ensures the stability of the assembly between the rod plate seat 22 and the push rod end of the linear actuator body 3.

[0029] In one embodiment, such as Figure 2 and 3 As shown, a hole block 31 is horizontally fixed to the end of the linear actuator body 3, and a cylinder seat 32 is provided on the bottom surface of the linear actuator body 3. A rod seat 35 is horizontally provided below the cylinder seat 32. The rod seat 35 is horizontally fixed and horizontally slidably assembled with the cylinder seat 32. A stud 33 is vertically fixed on the top surface of the cylinder seat 32, and the stud 33 passes through the hole block 31. A nut 34 is threaded onto the top of the stud 33. A second spring 37 is horizontally sleeved on the rod seat 35, and the two ends of the second spring 37 are respectively fixed to the rod seat 35 and the cylinder seat 32. The inner sides of the rod seat 35 are both horizontally fixed with second damping rods 36, and the other end of the second damping rods 36 is fixed to the cylinder seat 32. In use, the stud 33 at the top of the cylinder seat 32 passes through the hole block 31, and then the nut 34 cooperates with the stud 33 to lock the linear actuator body 3 and the cylinder seat 32. When the linear actuator body 3 is affected by the inertia generated when the path direction changes during the reciprocating motion of the actuator carried by the moving table 21, the cylinder seat 32 slides horizontally on the rod seat 35, compressing the second spring 37 to absorb the inertia. Then the deformation potential energy of the second spring 37 is offset by the damping force generated by the second damping rod 36, which further improves the accuracy of the linear actuator body 3.

[0030] In this embodiment, the push rod of the linear actuator body 3 pushes the moving platform 21 in the moving member 2 to slide horizontally on the guide rod frame 1. The reciprocating motion of the push rod of the linear actuator body 3 drives the moving platform 21 to slide horizontally back and forth on the guide rod frame 1. Then, the moving platform 21 bears the inertia generated when the path direction changes during the reciprocating motion of the actuator, causing the moving platform 21 to slide horizontally on the rod plate seat 22. The inertia of the moving platform 21 causes the first spring 23 to deform and offset the inertia of the moving platform 21. Then, the deformation potential energy of the first spring 23 is restored by the damping force of the first damping rod 24. The inertia generated when the moving platform 21 carries the actuator and changes its path direction during reciprocating motion is absorbed and canceled out. The stud 33 at the top of the cylinder seat 32 passes through the hole block 31, and then the nut 34 locks the linear actuator body 3 and the cylinder seat 32 together with the stud 33. When the linear actuator body 3 is affected by the inertia generated when the moving platform 21 carries the actuator and changes its path direction during reciprocating motion, the cylinder seat 32 slides horizontally on the rod seat 35, compressing the second spring 37 to deform and absorb the inertia. Then the deformation potential energy of the second spring 37 is canceled out by the damping force generated by the second damping rod 36.

[0031] The above are preferred embodiments of this utility model. 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 described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
