Description

Technical Field

[0001] The utility model relates to the technical field of electric control equipment, in particular to an external plug-in electric linear actuator. Background Art

[0002] Linear actuators are devices that convert energy (usually electrical energy) into linear motion and are widely used in automation technology, robotics, industrial control systems and other fields. Their basic function is to generate thrust or pull on a straight path to drive or manipulate a specific part of a mechanical system to move in a straight line. Linear actuators can be classified into electric, hydraulic, pneumatic, etc. according to their drive mode and implementation mechanism. The following is a brief description of the main types of linear actuators and some application scenarios:

[0003] (1) Type

[0004] 1. Electric actuators: These actuators use electric motors to convert rotary motion into linear motion through various mechanical mechanisms such as lead screws, racks, etc. They are suitable for applications that require precise control of position, speed, and force.

[0005] 2. Hydraulic actuators: Hydraulic actuators (also called hydraulic cylinders) use hydraulic pumps to push incompressible fluids to generate linear motion and force. They are suitable for use in environments where large force output is required but space is limited.

[0006] 3. Pneumatic actuators: Pneumatic actuators or cylinders use compressed air to generate motion. These actuators have a fast response speed, but the control accuracy is not as good as electric actuators. They are suitable for places where high speed requirements and medium force requirements are required.

[0007] (2) Application scenarios

[0008] Industrial Automation: Linear actuators are widely used in automated production lines, for example, to control the position, speed, and thrust of presses, sorting devices, conveying systems, etc.

[0009] Medical equipment: In the medical industry, linear actuators are used to adjust the height and angle of operating tables, or to drive the position adjustment of precision instruments such as mobile X-ray machines and CT scanners.

[0010] Automotive industry: Linear actuators are used in automotive technology for adjusting seat positions, opening and closing windows and sunroofs, and for installing components on automated production lines.

[0011] Home automation: In smart home systems, linear actuators are used to automatically open and close doors and windows, adjust the position of furniture components, etc. to improve comfort and convenience.

[0012] Linear actuators are widely used in many fields mainly because they can provide direct, efficient and easy-to-control linear motion solutions. With the continuous development of technology, the design and performance of linear actuators are also constantly optimized, and more and more high-performance and intelligent actuator products are being developed to meet the growing needs of different industries.

[0013] However, when general equipment is in use, the direction of linear execution cannot remain unchanged all the time, and when installing the equipment, the staff cannot determine whether the direction of linear execution is correct.

[0014] Therefore, in view of this, the existing deficiencies are studied and improved, and an external electric linear actuator is proposed. Utility Model Content

[0015] The purpose of the utility model is to provide an external plug-in electric linear actuator to solve the problems raised in the above background technology.

[0016] To achieve the above object, the utility model provides the following technical solution: an external plug-in electric linear actuator, comprising: an actuator body, one end of the actuator body is provided with an execution end, and the outer side of the execution end is provided with a calibration structure;

[0017] An assembly seat is arranged at one end of the actuator body, and a stabilizing structure is arranged at one side of the bottom end of the actuator body.

[0018] Furthermore, the calibration structure includes a slide groove, a calibration piece, a notch and a rotating shaft. A slide groove is provided at the upper end of the execution end, a rotating shaft is provided on the inner side of the slide groove, a calibration piece is provided on the top of the rotating shaft, and a notch is provided in the middle of the inner side of the calibration piece. Both the calibration piece and the notch are semicircular, so as to facilitate the alignment of the center point of the calibration piece with the midpoint of the diameter of the execution end.

[0019] Furthermore, a rotating structure is formed between the rotating shaft and the calibration piece, so that the rotating shaft can adjust the angle of the calibration piece.

[0020] Furthermore, a sliding structure is formed between the rotating shaft and the sliding groove, so that the rotating shaft can drive the calibration piece to move.

[0021] Furthermore, the center of the notch coincides with the midpoint of the diameter of the execution end, which makes it easy for the staff to calibrate the working direction of the execution end using the notch.

[0022] Furthermore, the stable structure includes a bottom frame, a vertical groove and a movable positioning piece. A bottom frame is provided on one side of the bottom end of the actuator body, a vertical groove is provided in the middle of the inner side of the bottom frame, and a movable positioning piece is provided at one end of the vertical groove. A sliding structure is formed between the movable positioning piece and the vertical groove to facilitate adjustment of the height of the movable positioning piece.

[0023] Furthermore, the bottom frame is fixedly connected to the actuator body to prevent the bottom frame from falling off.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] 1. The utility model moves the calibration piece at the top of the slide slot. At this time, the staff aligns the notch on the outside of the calibration structure with the working direction of the execution end, and uses the rotating shaft to adjust the angle between the calibration piece and the execution end, so as to ensure that the calibration piece, the notch and the execution end are on the same straight line, so that the working direction of the execution end remains correct;

[0026] 2. The utility model starts to adjust the distance between the movable positioning piece and the vertical slot by adjusting the movable positioning piece at one end of the inner vertical slot, so that the installation position of the actuator body can be set.

[0035] An assembly seat 4 is provided at one end of the actuator body 3 , and a stabilizing structure 5 is provided at one side of the bottom end of the actuator body 3 .

[0036] like Figure 1-Figure 5 As shown, an external plug-in electric linear actuator, the calibration structure 2 includes a slide groove 201, a calibration piece 202, a notch 203 and a rotating shaft 204, the upper end of the execution end 1 is provided with a slide groove 201, the inner side of the slide groove 201 is provided with a rotating shaft 204, the top of the rotating shaft 204 is provided with a calibration piece 202, the middle of the inner side of the calibration piece 202 is provided with a notch 203, the calibration piece 202 and the notch 203 are both semicircular, the calibration piece 202 at the upper end of the slide groove 201 is moved, and then the calibration piece 202 is rotated, at this time, the rotating shaft 204 at the bottom end of the calibration piece 202 drives the calibration piece 202 to move, when the notch 203 and the midpoint line of the execution end 1 are on the same straight line, the calibration piece 202 is stopped, and the effects and advantages brought about are as follows:

[0037] 1. Precise positioning: By moving and rotating the calibration sheet 202 with the notch 203, the user is allowed to manually adjust the position of the actuator 1 until the notch 203 is aligned with the midpoint line of the actuator 1. This design helps to achieve high-precision angle adjustment and position alignment.

[0038] 2. Easy operation: The user can complete the calibration process by simply physically moving and rotating the calibration piece 202, without the need for complex tools or program input, making the operation intuitive and convenient.

[0039] 3. Instant feedback: During the calibration process, the user can intuitively see the alignment of the notch 203 with the midpoint line of the actuator end 1, which provides instant visual feedback and helps the user complete the calibration more accurately.

[0040] 4. Improve equipment performance and accuracy: Accurate calibration ensures that mechanical equipment performs its tasks with accuracy and repeatability, which is especially important for applications that require high-precision operations, such as in assembly lines, precision machining or scientific research.

[0041] 5. Convenience of maintenance and adjustment: When the actuator 1 is offset due to long-term use or other reasons, the user can quickly correct it by adjusting the calibration piece 202 again without professional maintenance support, which improves the operating efficiency of the equipment and reduces maintenance costs. This calibration structure 2 is a practical physical adjustment tool used to ensure that the actuator 1 of the mechanical equipment can maintain a precise angle and position, thereby improving the operating accuracy and performance of the overall equipment, and is particularly suitable for technical fields with high requirements for precision operations.

[0042] like Figure 1-Figure 5 As shown, an external plug-in electric linear actuator, the stabilizing structure 5 includes a bottom frame 501, a vertical slot 502 and a movable positioning piece 503. The bottom frame 501 is arranged on one side of the bottom end of the actuator body 3, and the vertical slot 502 is arranged in the middle of the inner side of the bottom frame 501. The movable positioning piece 503 is arranged at one end of the vertical slot 502.

The vertical slot 502 moves with the movable positioning piece 503, and the installation height of the actuator body 3 is adjusted, which brings the following effects and advantages:

[0043] 1. Flexible height adjustment: Through the sliding structure between the vertical slot 502 and the movable positioning piece 503, the user can adjust the installation height of the actuator body 3 as needed. This design allows the actuator to be applied to operating environments with different height requirements, increasing the flexibility and applicability of the equipment.

[0046] 4. Increase the scope of application of the equipment: By allowing adjustments at different heights, the stable structure 5 increases the scope of application of the actuator body 3, so that the same equipment can be effectively used in a variety of working environments, thereby improving the economic benefits and application value of the equipment.

[0047] 5. Improve equipment efficiency and facilitate maintenance: When the actuator body 3 needs to be maintained or replaced, the height can be quickly changed by adjusting the movable positioning piece 503 to facilitate maintenance work. This flexible structural design also helps to improve the maintenance efficiency and convenience of the entire system. The design of the stable structure 5 not only provides stable support, but also provides the necessary height adjustment function for the actuator body 3, greatly enhancing the applicability and flexibility of the system, and is suitable for application scenarios that require frequent adjustment of height or position.

[0048] Working principle: When using the plug-in electric linear actuator, first move the actuator body 3 to a suitable position, and connect the assembly seat 4 to the external device, and then move the movable positioning piece 503 on one side of the bottom frame 501. The vertical slot 502 moves with the movable positioning piece 503, and then the installation height of the actuator body 3 is adjusted, and the calibration piece 202 at the upper end of the slide 201 is moved, and then the calibration piece 202 is rotated. At this time, the rotating shaft 204 at the bottom end of the calibration piece 202 drives the calibration piece 202 to move. When the notch 203 and the midpoint line of the actuator end 1 are on the same straight line, stop using the calibration piece 202, and then turn on the external power supply. This is the working principle of the plug-in electric linear actuator.
