Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and in particular to an electric actuator testing device when lifted. Background Technology

[0002] An electric linear actuator is an electric device that converts the rotary motion of a motor into linear reciprocating motion. It is widely used in industrial automation, medical equipment, smart homes, and other fields. Its core function is to drive a transmission structure, such as a screw, ball screw, or gear, to move the actuator, achieving reciprocating extension and retraction to push or pull objects. After the electric linear actuator is manufactured but before leaving the factory, it needs to undergo push-pull performance testing to determine whether it can provide sufficient driving force to push or pull the load within the design range under a certain load. This ensures that the quality and performance of the electric linear actuator meet standards. However, existing electric linear actuator testing benches can only provide testing for one indicator, either push or pull force, and cannot simultaneously meet the testing requirements for both. The former must be tested on one bench before transferring to another for the latter, which is cumbersome, time-consuming, and labor-intensive, easily leading to inaccurate test results and affecting testing efficiency and accuracy.

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 2As shown, the present invention discloses an electric push rod testing device for lifting, comprising a frame 1, a lifting device 2 movably mounted on the frame 1, an electric push rod 3 connected to the lifting device 2, and a load member 4 mounted on the frame 1. The lifting device 2 includes a lifting frame 21 and a swing rod 22 mounted on the lifting frame 21. Bearing seats 11 are provided on both sides of the frame 1, and bearings 12 are provided on the bearing seats 11. The bearings 12 are sleeved on the outside of the swing rod 22. A wire hole 23 is provided at the end of the lifting frame 21 away from the electric push rod 3. The electric push rod 3 is drivenly connected to the lifting frame 21 so that the lifting frame 21 swings around the bearing seat 11 via the swing rod 22.

[0025] This application mainly adopts a suspension structure. One end of the external rope is connected to the threaded hole 23 of the suspension frame 21, and the other end of the external rope is connected to the load component 4. The electric push rod 3 is driven by the suspension frame 21. When the electric push rod 3 extends and pushes the suspension frame 21 forward, the suspension frame 21 swings forward around the bearing seat 11 via the swing rod 22. When the electric push rod 3 retracts and pulls the suspension frame 21 backward, the suspension frame 21 swings backward around the bearing seat 11 via the swing rod 22. By adjusting the number of load components 4, the weight suspended by the suspension frame 21 is changed, and the two indicators of thrust and tension can be directly observed when the electric push rod 3 is carrying load components 4 of different weights. This utility model has a compact structure and reasonable design, integrating thrust and tension testing into one unit, simultaneously meeting the testing requirements of both thrust and tension indicators. It is easy and reliable to operate, ensures the accuracy of the test, and improves the testing efficiency and precision.

[0026] In this embodiment, the suspension bracket 21 has a right-angled triangular structure. The suspension bracket 21 is provided with reinforcing ribs 24, which are inclinedly arranged on the suspension bracket 21. Specifically, the right-angled triangular structure of the suspension bracket 21 provides strong structural stability and high load-bearing capacity, evenly distributes stress, avoids damage caused by concentrated stress, and has excellent performance. The inclined arrangement of the reinforcing ribs 24 effectively improves the overall structural rigidity of the suspension bracket 21, reduces deformation or displacement under stress, and disperses concentrated loads over a larger area, thereby reducing the level of local stress, further optimizing stress distribution, reducing excessive stress concentration, and also optimizing the external structural contour of the suspension bracket 21, resulting in better aesthetics.

[0027] In this embodiment, the end of the sling bracket 21 near the electric actuator 3 is provided with a connecting lug 25. The connecting lug 25 is provided with a connecting hole 26 so that an external screw can pass through the connecting hole 26 and connect to the output end of the electric actuator 3. Specifically, the external screw passes through the connecting hole 26 and connects to the output end of the electric actuator 3, thereby realizing the connection between the output end of the electric actuator 3 and the sling bracket 21, and the connection is stable and reliable.

[0028] In this embodiment, the frame 1 is provided with a support column 13, the support column 13 is provided with a mounting base 14, the frame 1 is provided with a connecting base 15, and a connecting rod 16 connects the mounting base 14 and the connecting base 15. The mounting base 14 is provided with a mounting groove 17 on the side near the electric push rod 3, and the mounting base 14 is provided with a mounting hole 18 communicating with the mounting groove 17. The electric push rod 3 is accommodated in the mounting groove 17 so that the electric push rod 3 is connected to the mounting hole 18. Specifically, the mounting base 14 is sleeved on the outside of the support column 13, and the connecting rod 16 connects the mounting base 14 and the connecting base 15 to further fix the position of the mounting base 14 on the support column 13. The electric push rod 3 is inserted and accommodated in the mounting groove 17, and then an external screw is used to pass through the mounting hole 18 and connect to the electric push rod 3, so that the electric push rod 3 is installed and fixed on the mounting base 14, ensuring the normal testing operation of the electric push rod 3.

[0029] In this embodiment, the supporting column 13 is provided with multiple hollow holes 19, which are arranged along the length direction of the supporting column 13. Specifically, the multiple hollow holes 19 are evenly distributed along the length direction of the supporting column 13. The multiple hollow holes 19 can reduce the overall weight of the supporting column 13 without sacrificing structural strength, effectively saving materials and reducing production costs.

[0030] In this embodiment, the electric linear actuator 3 is equipped with a power cord 31. Specifically, the main function of the power cord 31 of the electric linear actuator 3 is to transmit electrical energy from an external power source, such as a 24V or 12V DC power supply, to the motor inside the electric linear actuator 3, thereby driving the motor to operate. The motor further converts the circular motion into linear motion by rotating the worm gear and worm wheel, thereby driving the movement of the lead screw and nut to realize the extension and retraction of the actuator. Through the connection of the power cord 31, the electric linear actuator 3 can be controlled. For example, by changing the positive and negative terminals of the power cord 31, the extension and retraction direction of the electric linear actuator 3 can be controlled, that is, the actuator extends when rotating forward and retracts when rotating backward. In addition, the connection of the power cord 31 also supports the limit function of the electric linear actuator 3, ensuring that the actuator operates within a specified range.
