Description

Technical Field

[0001] This utility model belongs to the field of electrical actuator testing technology, and in particular relates to an electrical actuator testing bench. Background Technology

[0002] As a precision device that converts electrical signals into mechanical actions, the performance of electronic actuators directly affects the operational safety and reliability of equipment in key areas such as automotive, aerospace, and industrial automation. Therefore, comprehensive and rigorous performance testing is crucial during their production and R&D process, with flow tightness (i.e., media sealing and leakage performance) being one of the core indicators for evaluating their quality.

[0003] When using existing electronic actuator test benches, it is necessary to rely on the test bench to test the flow-sealing performance of the electronic actuators. However, when assembling the electronic actuators with the traditional test bench, the bolts between the actuators and the test bench need to be connected one by one. When a batch of electronic actuators need to be tested for flowability, this will be inconvenient, and the individual assembly will also lead to a reduction in sealing performance due to improper assembly. Utility Model Content

[0004] This utility model provides an electronic actuator test bench to solve the problem that in the prior art, when assembling an electronic actuator with a traditional test bench, it is necessary to connect and assemble the bolts between the actuator and the test bench one by one. When a batch of electronic actuators need to be tested for flowability, this is inconvenient, and the problem of reduced sealing due to improper assembly can also occur.

[0005] The present invention adopts the following technical solution: an electric actuator test bench, including a test bench frame, the top of the test bench frame is provided with a transverse groove, an electric push rod is installed inside the transverse groove, there are two electric push rods, the two electric push rods are symmetrically fixed in the transverse groove.

[0006] The inner sides of the two electric push rods are also fixedly connected to sliding brackets. The sliding brackets are pushed by the electric push rods to slide along the top of the test bench. The top of the sliding brackets is fixedly connected to a clamping plate. The inner sides of the clamping plates are fixedly connected to sealing rings. The clamping plates have through holes. A flow collector is embedded in the through holes. A connecting flange is fixedly connected to the side of the flow collector away from the clamping plate.

[0007] Compared with the prior art, the embodiments of this utility model achieve the following beneficial effects: This invention utilizes the pushing action between the electric push rod and the sliding bracket, and the sliding action between the guide block and the transverse groove of the test bench, to enable the sliding bracket to drive the clamping plate to quickly approach or move away from the actuator through the electric push rod. This differs from the existing method of assembling each actuator with bolts, enabling convenient operation for batch flow testing of electronic actuators and solving the problem of inconvenient assembly during batch testing in the prior art.

[0008] By fitting the sealing ring with the clamping plate and the actuator, inserting the limiting guide rod with the actuator flange, and tightening the connecting flange and the assembly flange with the fixing bolts, the actuator can be stably limited and the mating joint is well sealed. This avoids the reduction in sealing performance caused by poor assembly, ensures the accuracy of flowability testing, and solves the problem of poor assembly sealing affecting test results in the prior art.

Detailed Implementation

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0014] Reference Figures 1 to 6 As shown, this utility model embodiment provides an electric actuator test bench, a test bench 1, a transverse groove is provided at the top of the test bench 1, an electric push rod 2 is installed inside the transverse groove, there are two electric push rods 2 in total, the two electric push rods 2 are symmetrically fixed in the transverse groove; Specifically, the inner sides of the two electric push rods 2 are also fixedly connected to sliding brackets 201. The sliding brackets 201 are pushed by the electric push rods 2 to slide along the top of the test bench 1. The top of the sliding brackets 201 is fixedly connected to clamping plates 2012. There are two clamping plates 2012. The inner sides of the two clamping plates 2012 are fixedly connected to sealing rings 2013.

[0015] The clamping plate 2012 has a through hole inside, into which a flow collector 2015 is embedded. A connecting flange 2016 is fixedly connected to the side of the flow collector 2015 away from the clamping plate 2012. The sliding bracket 2 on the inner side is pushed by two symmetrical electric push rods 2 in the transverse groove at the top of the test bench 1, which in turn moves the two clamping plates 2012 at the top of the sliding bracket 201, facilitating docking with the actuator 3013. The sealing ring 2013 on the inner side of the clamping plate 2012 can improve the docking sealing. The flow collector 2015 in the through hole of the clamping plate 2012 and the connecting flange 2016 on the side away from the clamping plate 2012 provide a stable connection structure for the liquid delivery of the flowability test.

[0016] like Figure 1 As shown, specifically, a test water tank 1012 is fixedly connected to the bottom surface of the test bench 1. The test water tank 1012 is filled with test liquid. A water supply pipe 3 is fixedly connected to the left side of the test water tank 1012. The test water tank 1012 at the bottom of the test bench 1 can store test liquid, and the water supply pipe 3 on the left side can deliver the test liquid to the test part, providing a continuous liquid source for the flow sealing test of the electronic actuator.

[0017] like Figure 3As shown, specifically, a return pipe 3011 is fixedly connected to the right side of the test water tank 1012, and a water supply pump 301 is installed on the outer wall of the water supply pipe 3. The water supply pump 301 is used to draw liquid from the inside of the test water tank 1012 through the return pipe 3011. The return pipe 3011 on the right side of the test water tank 1012 cooperates with the water supply pump 301 on the outer wall of the water supply pipe 3. The water supply pump 301 can drive the return pipe 3011 to draw liquid from the test water tank 1012, realize the active delivery of the test liquid, and meet the liquid flow requirements of the flowability test.

[0018] like Figure 2 As shown, specifically, the return pipe 3011 is used to return the test liquid into the test water tank 1012. The side of the water supply pipe 3 and the return pipe 3011 away from the test water tank 1012 are both fixedly connected to the assembly flange 3012. The return pipe 3011 can return the tested liquid to the test water tank 1012, realizing liquid recycling. The assembly flange 3012 on the side of the water supply pipe 3 and the return pipe 3011 away from the test water tank 1012 provides a standardized interface for the connection of the pipeline to other components, ensuring the reliability of the connection.

[0019] like Figure 4 As shown, specifically, the assembly flange 3012 matches the connecting flange 2016. Both the connecting flange 2016 and the assembly flange 3012 have mounting holes arranged in a ring array inside. The connecting flange 2016 and the assembly flange 3012 are connected by a fixing bolt 2017. The matching of the assembly flange 3012 and the connecting flange 2016, and the connection of the ring array mounting holes inside them by the fixing bolt 2017, can ensure that the water supply pipe 3, the return pipe 3011 and the manifold 2015 are firmly connected, avoid liquid leakage during the test, and improve the test sealing performance.

[0020] like Figure 5 As shown, specifically, a guide block 2011 is fixedly connected to the outer wall of the sliding bracket 201. The guide block 2011 is a structure that protrudes from the sliding bracket 201. The sliding bracket 201 is slidably set in the transverse groove at the top of the test bench 1 through the guide block 2011. The protruding structure of the guide block 2011 on the outer wall of the sliding bracket 201 enables the sliding bracket 201 to slide smoothly in the transverse groove at the top of the test bench 1, improving the movement accuracy when the electric push rod 2 is pushed, and ensuring the docking accuracy between the clamping plate 2012 and the actuator 3013.

[0021] like Figure 6As shown, specifically, a support column 101 is fixedly connected to the bottom surface of the test bench 1. There are two support columns 101 in total, and the two support columns 101 are symmetrically fixed at the bottom of the test bench 1. A support beam 1011 is fixedly connected to the inner side of both sets of support columns 101. The two symmetrical support columns 101 at the bottom of the test bench 1 provide stable support for the test bench 1. The support beam 1011 on the inner side of the two sets of support columns 101 enhances the structural strength of the support columns 101, improves the overall stability of the test bench, and avoids the test results from being affected by shaking during the test.

[0022] like Figure 2 As shown, specifically, the clamping plate 2012 and the limiting guide rod 2014 clamp and limit the actuator 3013 on their inner sides. When the actuator 3013 is located within the two clamping plates 2012, the limiting guide rod 2014 is inserted into the two flange sections of the actuator 3013. The clamping plate 2012 and the limiting guide rod 2014 cooperate to clamp and limit the actuator 3013. When the actuator 3013 is located within the two clamping plates 2012, the limiting guide rod 2014 is inserted into the two flange sections of the actuator 3013, ensuring that the position of the actuator 3013 is fixed during testing and preventing displacement from interfering with the accuracy of the test.

[0023] Based on the above technical concept, in specific use, the support column 101 provides basic support for the test bench 1, and the support beam 1011 connects the support columns 101 on both sides to further distribute the force on the test bench 1, enhance the overall support stability, and provide a stable operating platform for subsequent testing. The actuator 3013 to be tested is placed on the top of the test bench 1 and between the two clamping plates 2012, ensuring that the flange position of the actuator 3013 corresponds to the position of the limit guide rod 2014. Then, the electric push rod 2 is activated, and the telescopic end of the electric push rod 2 generates a directional thrust, which directly acts on the sliding bracket 201 fixedly connected to it. Under the action of thrust, the sliding bracket 201 slides along the transverse groove at the top of the test bench 1 through the guide block 2011 on the outer wall. The guide block 2011 restricts the sliding direction of the sliding bracket 201 to avoid deviation during the movement, thereby driving the clamping plate 2012 at the top of the sliding bracket 201 to move synchronously towards the actuator 3013. As the clamping plate 2012 continues to move, its inner sealing ring 2013 first contacts the surface of the actuator 3013. As it continues to move until the clamping plate 2012 and the actuator 3013 are completely in contact, the sealing ring 2013 is squeezed and deformed, filling the gap between the clamping plate 2012 and the actuator 3013. At the same time, the limiting guide rod 2014 is inserted into the corresponding holes of the two flanges of the actuator 3013, thereby achieving the positioning and clamping of the actuator 3013. Remove the fixing bolt 2017, pass the fixing bolt 2017 through the mounting holes of the connecting flange 2016 and the assembly flange 3012, and rotate the fixing bolt 2017 to tighten it, thereby stably connecting the manifold 2015 with the water supply pipe 3 and the return pipe 3011, ensuring that there are no gaps at the pipe interface. Start the water supply pump 301. The water supply pump 301 generates suction to draw the test liquid from the test water tank 1012. The test liquid enters the water supply pipe 3 under the action of suction and is transported to the manifold 2015 through the water supply pipe 3. The manifold 2015 guides the test liquid to flow into the actuator 3013. By observing whether there is liquid leakage or flow obstruction in the actuator 3013, its flow sealing is judged. The test liquid flowing through the actuator 3013 enters the return pipe 3011 under its own gravity and the indirect action of the water supply pump 301, and then flows back to the test water tank 1012 through the return pipe 3011, forming a cycle of test liquid. After the actuator 3013 has been tested, the retaining bolt 2017 is rotated in the opposite direction to remove it, and the connection between the connecting flange 2016 and the assembly flange 3012 is released. Then, the electric push rod 2 is controlled to run in the opposite direction. The electric push rod 2 generates a pulling force to pull the sliding bracket 201. The sliding bracket 201 moves the clamping plate 2012 away from the actuator 3013. The limit guide rod 2014 is pulled out from the flange of the actuator 3013. Finally, the actuator 3013 is removed, completing a single test and preparing for the test of the next actuator 3013.

Various modifications and variations can be made to this utility model by those skilled in the art.
