Description

Technical Field

[0001] This utility model relates to the field of quality testing platform technology, specifically a quality testing platform for inverter production and processing. Background Technology

[0002] As is well known, a frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control an AC motor by changing the frequency of the motor's power supply. A frequency converter mainly consists of a rectification, filtering, inversion, braking unit, drive unit, detection unit, and microprocessor unit. Frequency converters also have many protection functions, such as overcurrent, overvoltage, and overload protection. With the continuous improvement of industrial automation, frequency converters have been widely used. When testing frequency converters, a test bench is required.

[0003] In existing quality testing benches used for inverter production and processing, anti-slip plates are a common configuration. Their core function is to increase the friction of the contact surface to achieve an anti-slip effect, preventing the inverter from sliding during testing due to vibration, external force, or other factors, thus ensuring the stability of the testing operation. However, the anti-slip plates of existing equipment mostly adopt a fixed installation structure, which is directly and rigidly connected to the main body of the testing bench. This design means that when the anti-slip plate wears or ages after long-term use, or needs to be replaced to adapt to different specifications of inverters, the disassembly process requires the use of special tools to gradually disassemble the fixed parts. The operation steps are cumbersome, which not only consumes a lot of manual time, but also affects the continuity of the testing process due to frequent shutdowns, thereby reducing the overall efficiency of production and testing. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a quality testing bench for inverter manufacturing and processing.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a quality testing bench for inverter manufacturing, comprising a base plate, a support base, an anti-slip plate, a cylinder, and a connecting mechanism. The support base is disposed at the bottom of the base plate, and two sets of support bases are provided. One end of the cylinder is connected to the anti-slip plate, and the other end of the cylinder passes through the base plate. Several connecting mechanisms are provided, each including a groove, an electric push rod, a connecting block, a limiting block, a sliding groove, a slider, a motor, and a threaded rod. The groove is formed on the side of the base plate, and one end of the electric push rod is connected to the anti-slip plate. The groove is connected to the inner wall of the groove. The other end of the electric push rod is connected to the connecting block. One end of the limiting block extends into the connecting block. The connecting block has a groove that matches the limiting block. The other end of the limiting block extends into the side of the anti-slip plate. The sliding groove is opened on the connecting block. One end of the slider extends into the sliding groove. The other end of the slider is connected to the limiting block. The motor is located at the bottom of the connecting block. The output end of the motor is connected to one end of the threaded rod. The other end of the threaded rod passes through the slider. The threaded rod is threadedly connected to the slider.

[0008] To facilitate operation of the equipment, the present invention is improved by providing a controller on the front of the base plate, the controller being electrically connected to the electric push rod, and the controller being electrically connected to the motor.

[0009] To improve stability, this utility model is improved by symmetrically arranging the two sets of support seats.

[0010] To improve stability, this invention features an improvement where the slider matches the groove.

[0012] To improve the strength of the support, this utility model is improved by making the support material of alloy steel.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a quality testing bench for inverter manufacturing and processing, which has the following beneficial effects:

[0015] This quality testing bench for inverter production and processing features a connection mechanism consisting of an electric push rod, a motor, a threaded rod, and limit blocks. This mechanism facilitates the easy assembly and disassembly of the anti-slip plate, solving the problem of time-consuming disassembly in traditional fixed structures and significantly improving replacement efficiency. Two sets of symmetrically distributed alloy steel support seats are stably connected to the base plate. Combined with the precise matching design of the slider and the groove, this ensures the structural stability of the entire equipment and its components. Multiple anti-slip grooves on the bottom of the anti-slip plate effectively increase friction, preventing the inverter from slipping during testing and ensuring reliable testing. The controller on the front of the base plate integrates control of the electric push rod and the motor, simplifying the operation process and improving ease of use. Simultaneously, the motor-driven lifting and lowering of the limit blocks allows for the adaptation of anti-slip plates of different thicknesses, enhancing the equipment's versatility and practicality. The overall structural design balances stability, convenience, and adaptability, meeting the actual needs of inverter production testing. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4A quality testing bench for inverter manufacturing includes a base plate 1, a support base 2, an anti-slip plate 3, a cylinder 4, and a connecting mechanism 5. The support base 2 is located at the bottom of the base plate 1, and two sets of support bases 2 are provided. One end of the cylinder 4 is connected to the anti-slip plate 3, and the other end of the cylinder 4 passes through the base plate 1. Several connecting mechanisms 5 are provided, each including a groove 6, an electric push rod 7, a connecting block 8, a limiting block 9, a sliding groove 10, a slider 11, a motor 12, and a threaded rod 13. The groove 6 is formed on the side of the base plate 1, and one end of the electric push rod 7 is connected to the inner wall of the groove 6. The other end of the push rod 7 is connected to the connecting block 8. One end of the limiting block 9 extends into the connecting block 8. The connecting block 8 has a groove that matches the limiting block 9. The other end of the limiting block 9 extends into the side of the anti-slip plate 3. The sliding groove 10 is opened on the connecting block 8. One end of the slider 11 extends into the sliding groove 10. The other end of the slider 11 is connected to the limiting block 9. The motor 12 is located at the bottom of the connecting block 8. The output end of the motor 12 is connected to one end of the threaded rod 13. The other end of the threaded rod 13 passes through the slider 11. The threaded rod 13 is threadedly connected to the slider 11.

[0023] Working principle: After placing the equipment in the designated position, the two sets of support bases 2 can provide stable support for the entire equipment. Then, connect the equipment to the external mains power supply, and it can be put into use.

[0024] During use, the staff places the inverter to be tested on the anti-slip plate 3 to prevent slippage when the inverter is in direct contact with the base plate 1, ensuring the stability of the inverter's position during the test. At this time, the staff can use external testing equipment to perform various performance tests on the inverter (the specific testing process will not be described in detail here).

[0025] When the anti-slip plate 3 needs to be replaced due to damage from long-term use, the operation procedure is as follows:

[0026] The staff activated the electric push rod 7, which moved the connecting block 8 away from the anti-slip plate 3, causing the limiting block 9 inside the connecting block 8 to separate from the limiting groove on the side of the anti-slip plate 3.

[0027] After the electric push rod 7 extends to its maximum stroke, the motor 12 is started. The motor 12 drives the threaded rod 13 to rotate. Since the threaded rod 13 is threadedly connected to the slider 11 and the slider 11 matches the slide groove 10 (it can slide stably along the slide groove 10), the slider 11 will drive the limit block 9 to rise along the groove on the connecting block 8 until the end of the limit block 9 that extends into the anti-slip plate 3 is higher than the surface of the anti-slip plate 3.

[0028] At this point, lifting the anti-slip plate 3 upwards will separate the cylinder 4 from the base plate 1, completing the disassembly of the old anti-slip plate 3;

[0029] When replacing the new anti-slip plate 3, it should be noted that the thickness of the new anti-slip plate 3 may vary (the thinnest model adapted to this structure is the basic reference). The height of its side limiting groove will change with the thickness. By starting the motor 12, repeat the above operation of the threaded rod 13 driving the slider 11 to raise and lower the limiting block 9. The limiting block 9 can be adjusted to a position that matches the height of the limiting groove of the new anti-slip plate 3, ensuring that the limiting block 9 can be stably inserted into the limiting groove to fix the new anti-slip plate 3. This design can be adapted to anti-slip plates 3 of different thicknesses, effectively improving the versatility and practicality of the equipment.

[0030] To facilitate equipment operation, a controller 14 is installed on the front of the base plate 1 in this embodiment. As the core control unit for equipment operation, the controller 14 is electrically connected to the electric push rod 7 and the motor 12, and can centrally control the operating status of both. The controller 14 can precisely control the extension and retraction of the electric push rod 7 to achieve displacement adjustment of the connecting block 8. At the same time, it can control the start, stop and forward / reverse rotation of the motor 12 to drive the threaded rod 13 to rotate and drive the slider 11 and the limit block 9 to rise and fall. This integrated control design simplifies the operation process. The operator does not need to operate each component separately. The disassembly and replacement of the anti-slip plate 3 can be completed through the controller 14, which greatly improves the convenience of operation.

[0031] To improve the overall stability of the equipment, in this embodiment, the two sets of support seats 2 are arranged symmetrically and fixed to the bottom sides of the base plate 1 respectively. This symmetrical layout can make the support points evenly distributed on both sides of the center of gravity axis of the base plate 1, ensuring that the equipment is balanced under force when placed, avoiding tilting or shaking due to uneven weight distribution. At the same time, the symmetrical structure can evenly transfer the pressure generated when the frequency converter is placed and the vibration load during the test to the support surface, reducing local stress concentration and reducing the risk of deformation of the base plate 1 due to uneven force distribution. Combined with the alloy steel material used for the support seats 2, its high strength characteristics and symmetrical distribution of support form a synergistic effect, further enhancing the structural stability of the equipment during test operations.

[0032] To improve the stability of equipment operation, the slider 11 and the slide groove 10 in this embodiment adopt a precise matching design. The slide groove 10 is opened on the connecting block 8, and its size and shape are completely adapted to the slider 11, ensuring that the slider 11 can slide smoothly along the slide groove 10 without obvious gaps. This matching structure can limit the movement trajectory of the slider 11 and prevent it from deviating or shaking when rotating with the threaded rod 13, thereby ensuring the stability of the lifting process of the limit block 9. At the same time, the tight fit can reduce the vibration transmission between components and prevent the limit block 9 and the anti-slip plate 3 from deviating due to loosening. This improves the operational reliability of the connecting mechanism 5 from the details and provides structural protection for the stable fixation and convenient disassembly and assembly of the anti-slip plate 3.

[0033] To improve the anti-slip effect, the bottom of the anti-slip plate 3 in this embodiment is provided with several anti-slip patterns. These anti-slip patterns adopt a regularly arranged concave-convex structure, which can significantly improve the friction between the anti-slip plate 3 and the placement surface by increasing the roughness of the contact surface. When the frequency converter is placed on the anti-slip plate 3, the anti-slip patterns can effectively block the relative sliding tendency between the bottom surface of the frequency converter and the surface of the anti-slip plate 3, and avoid the frequency converter from shifting due to slight vibration or external force during the test. The distribution design of multiple anti-slip patterns further ensures the uniformity of friction. Even if the placement position of the frequency converter is slightly deviated, it can still maintain a stable state, providing a basic guarantee for the safety and accuracy of the test process.

[0034] To improve the structural strength of the support base 2, in this embodiment, the support base 2 is made of alloy steel. By adding alloying elements such as chromium, nickel, and manganese to the steel, the tensile strength, yield strength, and wear resistance of the material are significantly improved, which is far superior to ordinary carbon steel. As the main load-bearing component of the base plate 1, the support base 2 needs to bear the weight of the equipment itself and the dynamic load generated during the frequency converter test for a long time. The use of alloy steel can effectively resist deformation or fracture caused by external forces and extend its service life. At the same time, alloy steel has strong corrosion resistance, which can reduce the wear and tear of the support base 2 caused by environmental factors during long-term use, ensuring that it always maintains a stable support effect and providing a reliable guarantee for the structural stability of the entire test bench.
