Description

Technical Field

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

[0002] With the rapid development of electrical automation technology, various electrical equipment is increasingly widely used in industrial control, energy management, intelligent manufacturing and other fields. To ensure the stability, safety and reliability of these devices in actual operation, comprehensive and accurate performance testing is necessary. Traditional electrical testing relies heavily on manual operation, which is not only inefficient, but also makes it difficult to guarantee the accuracy and consistency of testing, and cannot meet the modern industrial demand for high-efficiency, high-precision and high-automation testing. To solve the above problems, electrical automation test benches have emerged. These test benches integrate automatic control systems, sensor technology and data acquisition and analysis modules to realize the automated testing and monitoring of various parameters of electrical equipment.

[0003] Traditional electrical automation test benches typically have fixed clamping blocks, which require various tools to disassemble and adjust when dealing with test pieces of different sizes. This process is cumbersome and time-consuming, limiting the applicability of the equipment.

[0004] Therefore, those skilled in the art have provided an electrical automation test bench to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an electrical automation test bench. By cooperating with the threaded rod and the threaded sleeve, rotating the threaded rod can drive the threaded sleeve and the limiting block to move, pushing the locking block and the protrusion to disengage, thereby quickly separating the clamping block and the mounting block. This allows operators to change clamping blocks of different specifications without complicated tools, shortening the replacement time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An electrical automation test bench includes a test bench body. A clamping mechanism is provided at the front of the upper end of the test bench body. An installation mechanism is provided on the outer wall of the clamping mechanism. The installation mechanism includes two installation blocks. Cavities are formed at both ends of the inner walls of the two installation blocks. Threaded rods are rotatably connected to one end of each cavity near the center of the installation block. Threaded sleeves are fitted on the outer walls of the threaded rods. Limiting blocks are fixedly connected to both sides of the threaded sleeves. Two connecting rods are fixedly connected to one end of each threaded sleeve near the center of the installation block. A locking block is fixedly connected to one end of each adjacent connecting rod near the center of the installation block. A groove is formed in the middle of the upper end of each of the two installation blocks. Protrusions are provided on the inner walls of the two grooves. Through the above technical solution, by cooperating with the threaded rod and the threaded sleeve, rotating the threaded rod drives the threaded sleeve and the limiting block to move, thereby driving the locking block to move and disengage from the protrusion, quickly disconnecting the clamping block from the mounting block. This allows operators to quickly change clamping blocks of different specifications according to the size of different test pieces without complicated tools or cumbersome steps.

[0007] Furthermore, fixed blocks are fixedly connected to both sides of the upper end of the test platform body, a bidirectional threaded rod is rotatably connected to the front end of the inner wall of the fixed block on the other side, a sliding rod is rotatably connected to the rear end of the inner wall of the fixed block on the other side, a servo motor is provided at the front end of the inner wall of the fixed block on one side, a clamping block is fixedly connected to the upper end of both protrusions, the front ends of the inner walls of both mounting blocks are threadedly connected to the bidirectional threaded rod, and the rear ends of the inner walls of both mounting blocks are slidably connected to the sliding rod. The above technical solution involves starting a servo motor to drive a bidirectional threaded rod to rotate. As the bidirectional threaded rod rotates, the mounting block and its upper structure move accordingly, providing a stable clamp to the electrical equipment and preventing it from shaking during testing. In this process, the sliding rod acts as a guide, effectively preventing the mounting block from shaking or getting stuck during movement.

[0008] Furthermore, a control device is provided at the rear of the upper end of the test bench body, and two cabinet doors are provided at the front end of the test bench body; Through the above technical solutions, the control device facilitates centralized control of equipment operation by operators, and the cabinet door facilitates the inspection and maintenance of internal components.

[0009] Furthermore, all of the aforementioned card blocks are engaged with both ends of the protrusion; The above technical solution enhances the connection stability between the clamping block and the mounting block, preventing loosening or displacement during testing.

[0010] Furthermore, one end of each of the threaded rods located away from the center of the mounting block extends through the mounting block to the outside of the mounting block; The above technical solution allows operators to directly rotate the threaded rod externally, improving operational convenience.

[0011] Furthermore, all of the threaded sleeves are threadedly connected to the threaded rod, and all of the limiting blocks slide on the inner wall of the cavity; Through the above technical solution, the threaded connection ensures that the rotational transmission is linear motion, and the limiting block slides on the inner wall of the cavity, playing a guiding and limiting role, preventing the threaded sleeve from deviating or getting stuck during the movement.

[0012] Furthermore, one end of each of the connecting rods near the center of the mounting block penetrates the cavity and groove into the groove; The above technical solution enables the linkage between the locking block and the protrusion, ensuring coordination and consistency when releasing or locking.

[0013] Furthermore, the output end of the servo motor is fixedly connected to the bidirectional threaded rod, and one side of the slide rod is rotatably connected to the fixed block; Through the above technical solution, the servo motor and the bidirectional threaded rod are connected to achieve high-precision and automated clamping action control, and the slide bar provides good guiding support to prevent the mounting block from shaking or getting stuck during movement.

[0014] This utility model has the following beneficial effects: 1. The electrical automation test bench proposed in this utility model uses the cooperation of a threaded rod and a threaded sleeve. Rotating the threaded rod drives the threaded sleeve and the limiting block to move, thereby driving the clamping block to move and disengage from the protrusion, quickly disconnecting the clamping block from the mounting block. This allows operators to quickly change clamping blocks of different specifications according to the size of different test pieces without complicated tools or cumbersome steps. This not only shortens the changeover time but also expands the applicability of the equipment and improves the overall work efficiency and flexibility. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides a specific implementation method: An electrical automation test bench includes a test bench body 4. A clamping mechanism 2 is provided at the front of the upper end of the test bench body 4. An installation mechanism 1 is provided on the outer wall of the clamping mechanism 2. The installation mechanism 1 includes two installation blocks 101. Cavities 102 are opened at both ends of the inner wall of the two installation blocks 101. Threaded rods 103 are rotatably connected to one end of the multiple cavities 102 near the center of the installation blocks 101. Threaded sleeves 104 are fitted on the outer wall of the multiple threaded rods 103. Limiting blocks 105 are fixedly connected to both sides of the multiple threaded sleeves 104. Two connecting rods 106 are fixedly connected to one end of the multiple threaded sleeves 104 near the center of the installation blocks 101. A locking block 107 is fixedly connected to one end of the adjacent connecting rods 106 near the center of the installation blocks 101. Grooves 109 are opened in the middle of the upper end of the two installation blocks 101. Protrusions 108 are provided on the inner wall of the two grooves 109. By engaging the threaded rod 103 with the threaded sleeve 104, rotating the threaded rod 103 causes the threaded sleeve 104 and the limiting block 105 to move, which in turn causes the locking block 107 to move and disengage from the protrusion 108, quickly disconnecting the clamping block 6 from the mounting block 101. This allows operators to quickly replace clamping blocks 6 of different specifications according to the size of different test pieces without the need for complicated tools or cumbersome steps.

[0019] Reference Figure 4 , Figure 5 and Figure 6The test platform body 4 has two fixed blocks 201 fixedly connected to the upper end of the two sides. The front end of the inner wall of the other fixed block 201 is rotatably connected to a bidirectional threaded rod 202, and the rear end of the inner wall of the other fixed block 201 is rotatably connected to a sliding rod 203. A servo motor 204 is set at the front end of the inner wall of one fixed block 201. Clamping blocks 6 are fixedly connected to the upper ends of the two protrusions 108. The front ends of the inner walls of the two mounting blocks 101 are threadedly connected to the bidirectional threaded rod 202, and the rear ends of the inner walls of the two mounting blocks 101 are slidably connected to the sliding rod 203. When the servo motor 204 is started, it drives the bidirectional threaded rod 202 to rotate. As the bidirectional threaded rod 202 rotates, the mounting block 101 and its upper structure move accordingly, clamping the electrical equipment securely and preventing it from shaking during testing. During this process, the sliding rod 203 acts as a guide, effectively preventing the mounting block 101 from shaking or getting stuck during movement. A control device 3 is provided at the rear of the upper end of the test bench body 4, and two cabinet doors 5 are provided at the front end of the test bench body 4. The control device 3 facilitates centralized control of the equipment operation by the operator, and the cabinet doors 5 facilitate the inspection and maintenance of the internal components of the equipment. Multiple locking blocks 107 are engaged with both ends of the protrusion 108. The connection stability between the clamping block 6 and the mounting block 101 is enhanced to prevent loosening or displacement during testing. Multiple threaded rods 103, with one end furthest from the center of the mounting block 101, penetrate the mounting block 101 to the outside, allowing operators to directly rotate the threaded rods 103 from the outside, improving operational convenience. Multiple threaded sleeves 104 are threadedly connected to the threaded rods 103, and multiple limiting blocks 105 slide on the inner wall of the cavity 102. The threaded connection ensures linear motion from rotational transmission, while the limiting blocks 105 slide on the inner wall of the cavity 102, serving as guides and limiters to prevent the threaded sleeves 104 from moving. If deviation or jamming occurs during the process, the ends of multiple connecting rods 106 near the center of the mounting block 101 all penetrate through the cavity 102 and the groove 109 to the inside of the groove 109, realizing the linkage between the locking block 107 and the protrusion 108, ensuring coordinated engagement or disengagement. The output end of the servo motor 204 is fixedly connected to the bidirectional threaded rod 202, and one side of the slide rod 203 is rotatably connected to the fixed block 201. The connection between the servo motor 204 and the bidirectional threaded rod 202 realizes high-precision and automated clamping action control. The slide rod 203 provides good guiding support to prevent the mounting block 101 from shaking or jamming during movement.

[0020] Working principle: When using the device, the user rotates the threaded rod 103 to move the threaded sleeve 104 and the limiting block 105, which in turn moves the connecting rod 106. As the connecting rod 106 moves, the protrusion 108 moves accordingly. Disengaging from the protrusion 108, the user then removes the protrusion 108 and the clamping block 6 from the groove 109. To replace the clamp with a different size, the user places the new clamp and protrusion 108 back into the groove 109 and rotates the threaded rod 103 in the opposite direction, causing the clamping block 107 to re-engage with the protrusion 108. This allows for quick replacement of the clamp. The fixture is then installed on the mounting block 101. The electrical equipment to be tested is then placed on one side of the fixture. The servo motor 204 is then started to drive the bidirectional threaded rod 202 to rotate. As the bidirectional threaded rod 202 rotates, the mounting block 101 and its upper structure move accordingly, clamping and fixing the electrical equipment. During this process, the sliding rod 203 acts as a guide, effectively preventing the mounting block 101 from shaking or jamming during movement, ensuring a stable and reliable clamping process. Subsequently, the electrical equipment can be tested through the control equipment.
