Abstract

This utility model discloses a torque detection device for an electric actuator, belonging to the field of electric actuator testing technology. The device includes a base, a placement platform, a testing platform, and a controller. The placement platform is mounted on the surface of the base, and the testing platform is mounted on the placement platform. The controller is located on the side of the base, and a positioning mechanism is mounted on the surface of the base. The positioning mechanism includes a push cylinder, a push rod, a housing, and an adjustment component. In this utility model, by setting up a positioning mechanism, the operation of the push cylinder reduces the distance between two sets of positioning components, so that the two sets of positioning components clamp the electric actuator located in the middle, pressing the position of the electric actuator and making the electric actuator stably attached to the testing platform. This prevents the electric actuator from shaking or wobbling due to its own operation, which could lead to loosening or damage at the connection between the actuator and the testing end, thus achieving the locking of the electric actuator position.

Description

Technical Field

[0001] This utility model belongs to the field of electric actuator testing technology, specifically relating to a torque testing device for electric actuators. Background Technology

[0002] Electric actuators are used to drive valves to the fully open or fully closed position. They are mainly used to control the valve's closing angle. By utilizing the operation of the actuator, the valve can be precisely moved to any position. They are a commonly used tool in valve operation. Modern electric actuators require multiple testing processes after manufacturing, including torque testing.

[0003] Current testing equipment consists of a testing platform and a controller. The electric actuator to be tested is placed on the testing platform, ensuring that the output end of the electric actuator is connected to the testing end in the testing platform. The torque of the electric actuator is accurately detected by the controller. However, there are some problems in actual use. Specifically, the actuator will vibrate and shake during the testing process. As the actuator shakes, the connection between the actuator and the testing end may become loose or damaged, which will affect the overall performance of the equipment. Utility Model Content

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] A torque detection device for an electric actuator includes a base, a placement platform, a detection platform, and a controller. The placement platform is mounted on the surface of the base, and the detection platform is mounted on the placement platform. The controller is located on the side of the base. A positioning mechanism is mounted on the surface of the base. The positioning mechanism includes a push cylinder, a push rod, a housing, and an adjustment component. The push cylinder is mounted on one side of the base surface. The push rod is mounted on the output end of the push cylinder. The housing is mounted on the end of the push rod. The adjustment component is mounted inside the housing. Positioning elements are symmetrically arranged above the base.

[0007] As a preferred technical solution of this utility model, the positioning mechanism further includes a mounting seat. The mounting seat is installed on the surface of the base and on the side opposite to the push cylinder. There are two sets of outer shells, one set of outer shells is installed on the end of the push rod, and the other set of outer shells is installed on the side of the mounting seat.

[0008] As a preferred embodiment of this utility model, the adjustment component includes a lead screw, a moving end, and a rotating end. The lead screw is rotatably installed inside the outer casing, and the moving end is threadedly installed on the outside of the lead screw. The moving end is connected to a positioning component, and the rotating end is rotatably installed on the top of the outer casing. The rotating end is connected to the end of the lead screw.

[0009] As a preferred embodiment of this utility model, the adjustment component further includes a guide rod, which is fixedly installed inside the outer casing. The guide rod is parallel to the lead screw and is slidably connected to the moving end.

[0010] As a preferred technical solution of this utility model, the positioning component is composed of an extrusion plate and a protective plate. An extrusion plate is installed on the side of the moving end, and anti-slip grooves are equidistantly provided on the extrusion plate. A protective plate is symmetrically installed on the top of the extrusion plate.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0024] like Figure 1 , Figure 2 and Figure 6 As shown, this is a schematic diagram of the torque detection device for the electric actuator in this embodiment. The device includes a base 1, a placement platform 2, a detection platform 3, and a controller 4. The placement platform 2 is mounted on the surface of the base 1. The placement platform 2 includes a slide 21, a guide rail 22, and a pressing screw 23. The guide rail 22 is symmetrically mounted on the surface of the base 1. The slide 21 is mounted on the guide rail 22. The pressing screw 23 is threaded onto the side of the slide 21 and penetrates the side wall of the slide 21. The detection platform 3 is mounted on the slide 21. The controller 4 is provided on the side of the base 1. The positioning mechanism 6 is mounted on the surface of the base 1.

[0025] The electric actuator to be tested is placed on the testing table 3, and then the output end of the electric actuator is connected to the testing end in the testing table 3. Then, the torque of the electric actuator is accurately detected by the controller 4. In use, the slide table 21 is pushed to make the slide table 21 slide stably on the guide rail 22, and the position of the testing table 3 and the electric actuator is adjusted to facilitate the subsequent placement and replacement of the electric actuator. The position of the slide table 21 is locked by the rotation of the extrusion screw 23.

[0026] As attached Figure 3 and Figure 4 As shown, this is a schematic diagram of the positioning mechanism 6 in this embodiment. The positioning mechanism 6 includes a push cylinder 61, a push rod 62, a housing 63, and an adjustment component 64. The push cylinder 61 is installed on one side of the surface of the base 1. The push rod 62 is installed at the output end of the push cylinder 61. The housing 63 is installed at the end of the push rod 62. The adjustment component 64 is installed inside the housing 63. Positioning members 5 are symmetrically arranged above the base 1. A mounting seat 65 is installed on the surface of the base 1 on the side opposite to the push cylinder 61. There are two sets of housings 63. One set of housings 63 is installed at the end of the push rod 62, and the other set of housings 63 is installed on the side of the mounting seat 65.

[0027] When the electric actuator is placed on the testing table 3, the slide table 21 is pushed first to bring one side of the electric actuator into contact with the positioning part 5 on the side of the mounting base 65. Then, by using the cylinder 61, the output end of the cylinder 61 is pushed to drive the push rod 62 to move. At this time, one set of housings 63 moves closer to the testing table 3, and the other set of positioning parts 5 pushes the housing of the electric actuator. Under the pressure of the two sets of positioning parts 5, the position of the electric actuator is locked to ensure the stability of the electric actuator during testing.

[0028] As attached Figure 5 As shown, this is a schematic diagram of the structure of the adjustment component 64 in this embodiment. The adjustment component 64 includes a lead screw 641, a moving end 642, and a rotating end 643. The lead screw 641 is rotatably installed inside the outer shell 63. The moving end 642 is threadedly installed on the outside of the lead screw 641 and is connected to the positioning member 5. The rotating end 643 is rotatably installed on the top of the outer shell 63 and is connected to the end of the lead screw 641. A guide rod 644 is fixedly installed inside the outer shell 63. The guide rod 644 is parallel to the position of the lead screw 641 and is slidably connected to the moving end 642.

[0029] When positioning electric actuators with different housing shapes, the rotating end 643 is rotated, at which point the lead screw 641 rotates entirely inside the housing 63, and the moving end 642 moves along the external thread direction of the lead screw 641 to adjust the position and height of the positioning part 5, so that the inner wall of the positioning part 5 can be stably fitted with the housing of the electric actuator.

[0030] As attached Figure 4 As shown, the positioning component 5 is composed of an extrusion plate 51 and a protective plate 52. The extrusion plate 51 is installed on the side of the moving end 642. Anti-slip grooves are equidistantly opened on the extrusion plate 51. The protective plate 52 is symmetrically installed on the top of the extrusion plate 51. Placement grooves are provided between the protective plates 52, and the inner wall of the protective plate 52 is provided with a rubber layer.

[0031] As the positioning mechanism 6 operates, the extrusion plate 51 extrudes against the side wall of the electric actuator to clamp the position of the electric actuator, while the protective plate 52 presses down on the top of the electric actuator to prevent the electric actuator from shaking up and down during the testing process.

[0032] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
