Description

Technical Field

[0001] This utility model relates to the field of working technology, and in particular to a device for fixing and supporting the test piece of a high-voltage test bench. Background Technology

[0002] In modern industrial production and scientific research, high-voltage testing, as a key testing method, is widely used in many fields such as power, electronics, and electrical equipment manufacturing. Its purpose is to evaluate the performance, insulation characteristics, withstand voltage, and other key indicators of various electrical products, materials, and components under high-voltage environments to ensure the safety and reliability of products in actual operation. In power systems, core equipment such as high-voltage transformers and high-voltage switchgear must undergo rigorous high-voltage testing before being put into use to verify whether they can withstand the high-voltage impacts of the power grid operation. In the electronic equipment manufacturing industry, high-voltage power modules, high-voltage capacitors, and other components also need to undergo high-voltage testing to ensure their normal operation in products.

[0003] In the high-voltage testing process, the device for fixing and supporting the test piece plays a crucial role. This device must not only provide stable and reliable support for the test piece to ensure that it does not shift or shake during the test, but also achieve precise positioning of the test piece so that the testing equipment can accurately apply high voltage and collect relevant test data. As the core component of the device for fixing and supporting the test piece, the clamping device directly contacts the test piece and fixes it. Its performance has a direct impact on the quality and efficiency of the high-voltage test.

[0004] Currently, most clamping devices in the fixed support devices of high-voltage test benches on the market adopt a fixed connection clamping plate structure. With the rapid development of technology and the continuous changes in market demand, the types of electrical products, materials and components are becoming increasingly diverse, and their shapes, sizes, materials and other characteristics vary greatly. In high-voltage testing, the test components may include small electronic chips, thin high-voltage cables, large transformer cores, etc. For different types of test components, it is often necessary to use a clamping plate that is compatible with them to achieve a good fixing effect. The existing traditional fixed connection clamping plates are difficult to disassemble and replace once installed on the clamping device. This means that when it is necessary to test test components of different specifications, the operator has to spend a lot of time and energy to adjust or even replace the entire clamping device, which seriously affects the testing efficiency and increases production costs. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a fixed support device for the test piece of a high-voltage test bench. This device can solve the problem that once the clamping plate is fixedly connected, it is difficult to disassemble and replace. This means that when different specifications of test pieces need to be tested, the operator has to spend a lot of time and effort to adjust or even replace the entire clamping device, which seriously affects the testing efficiency and increases the production cost.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a test piece fixing support device for a high voltage test bench, including a mounting base and a rotating base, wherein two limiting components are provided on the rotating base; The limiting assembly includes a support plate, a clamping plate, and a connecting plate. The support plate is fixedly installed on the upper surface of one side of the rotating seat. Two T-shaped block grooves are opened on the outer wall of the connecting plate. A cylinder is fixedly installed on the outer wall of the support plate. A fixing block is fixedly connected to the upper outer wall of the clamping plate. A second limiting block groove is opened on both sides of the outer wall of the fixing block. The connecting plate has two protective shells fixedly connected to its upper surface. Each of the two protective shells has a first limiting block groove on its outer wall on the opposite side. Each of the two first limiting block grooves has a limiting block slidably connected inside. Each of the two protective shells has a rotating threaded rod sleeve rotatably connected to its outer wall. Each of the two first limiting block grooves has a rotating threaded rod inside. Both limiting components are set on the upper surface of the rotating seat and work together with each other.

[0007] Preferably, the clamping plate is L-shaped, and the output end of the cylinder slides to the outside of the support plate and is fixedly connected to the outer wall of the connecting plate; Among them, the outer walls of the two T-shaped blocks on one side of the clamping plate are slidably connected to the interior of the corresponding T-shaped block grooves.

[0008] Preferably, the two sliding rods slidably connected on the support plate extend slidably to the outside of the support plate at the end near the connecting plate and are fixedly connected to the outer wall of the connecting plate; In this configuration, the ends of the two limiting blocks near the second limiting block groove both slide to the outside of the first limiting block groove and are respectively slidably connected to the inside of the corresponding second limiting block groove.

[0009] Preferably, the ends of the two rotating threaded rod sleeves near the limiting block both extend rotatably into the interior of the first limiting block groove, and the ends of the two rotating threaded rods near the limiting block are respectively fixedly connected to the outer wall of the corresponding limiting block; The ends of the two rotating threaded rods furthest from the limiting block are respectively connected to the internal threads of the corresponding rotating threaded rod sleeves.

[0010] Preferably, a second rotating gear is rotatably connected inside a groove on the upper surface of the mounting base, and the lower surface of the rotating base is fixedly connected to the upper surface of the second rotating gear. The motor is fixedly installed inside the groove on the upper surface of the mounting base.

[0011] Preferably, the output end of the motor is fixedly connected to a first rotating gear, and the outer teeth of the first rotating gear mesh with the outer teeth of the second rotating gear. Mounting plates are provided on both sides of the lower end of the mounting base.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The test piece fixing support device of this high-voltage test bench uses a rotating threaded sleeve in the limiting assembly. Due to the threaded engagement between the rotating threaded sleeve and the rotating threaded rod, the rotating threaded rod, driven by the rotating threaded sleeve, drives the limiting block to move in the opposite direction to the fixed block. Finally, the limiting block is disengaged from the second limiting block groove of the fixed block, allowing the limiting block to slide out of the second limiting block groove, thus releasing the lock on the clamping plate. Then, the clamping plate can be pulled to remove it from the connecting plate. This method of disassembling the clamping plate is simple and quick, effectively improving the disassembly efficiency of the clamping plate and reducing the workload of the operator.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a fixed support device for the test piece of a high voltage test bench, including a mounting base 1 and a rotating base 2; Two limit components are provided on the rotating base 2; The limiting assembly includes a support plate 4, a clamping plate 5, and a connecting plate 9. The support plate 4 is fixedly installed on the upper surface of one side of the rotating seat 2. The outer wall of the connecting plate 9 has two T-shaped block grooves 10. The clamping plate 5 is L-shaped. A cylinder 3 is fixedly installed on the outer wall of the support plate 4. The output end of the cylinder 3 slides to the outside of the support plate 4 and is fixedly connected to the outer wall of the connecting plate 9. The outer walls of the two T-shaped blocks on one side of the clamping plate 5 are slidably connected to the interior of the corresponding T-shaped block grooves 10. The ends of the two sliding rods slidably connected on the support plate 4 near the connecting plate 9 both slide to the outside of the support plate 4 and are fixedly connected to the outer wall of the connecting plate 9. A fixing block 6 is fixedly connected to the upper outer wall of the clamping plate 5. The outer walls on both sides of the fixing block 6 are provided with second limiting block grooves 16. Two protective shells 7 are fixedly connected to the upper surface of the connecting plate 9. The outer walls on the opposite sides of the two protective shells 7 are provided with... The first limiting block groove 14 has two limiting blocks 13 slidably connected inside each first limiting block groove 14. The ends of the two limiting blocks 13 near the second limiting block groove 16 slidably extend to the outside of the first limiting block groove 14 and are slidably connected to the inside of the corresponding second limiting block groove 16. The outer walls of the two protective shells 7 are rotatably connected with rotating threaded rod sleeves 8. The inside of the two first limiting block grooves 14 is provided with rotating threaded rods 15. The ends of the two rotating threaded rod sleeves 8 near the limiting block 13 slidably extend to the inside of the first limiting block groove 14. The ends of the two rotating threaded rods 15 near the limiting block 13 are fixedly connected to the outer wall of the corresponding limiting block 13. The ends of the two rotating threaded rods 15 away from the limiting block 13 are threadedly connected to the inside of the corresponding rotating threaded rod sleeves 8. The two limiting components are both set on the upper surface of the rotating seat 2 and cooperate with each other.

[0020] The mounting base 1 has a groove on its upper surface that is rotatably connected to a second rotating gear 12. The lower surface of the rotating base 2 is fixedly connected to the upper surface of the second rotating gear 12. A motor 17 is fixedly installed inside the groove on the upper surface of the mounting base 1. The output end of the motor 17 is fixedly connected to a first rotating gear 11. The teeth on the outer wall of the first rotating gear 11 mesh with the teeth on the outer wall of the second rotating gear 12. Mounting plates are provided on both sides of the lower end of the mounting base 1.

[0021] Furthermore, when using this device, firstly, the mounting base 1 installs the entire clamping device in the designated position via two mounting plates. Then, when it is necessary to adjust the angle position of the workpiece to be tested, the motor 17 is started. The motor 17 drives the first rotating gear 11 to rotate. Since the first rotating gear 11 meshes with the second rotating gear 12, the second rotating gear 12 rotates accordingly, thereby driving the rotating seat 2, which is fixedly connected to it, to rotate around the central axis of the mounting base 1. By controlling the rotation direction and angle of the motor 17, the position of the rotating seat 2 can be precisely adjusted so that the workpiece to be tested reaches the required test angle. Next, after the workpiece to be tested is placed in the appropriate position between the two clamping plates 5, the cylinder 3 is started. The output end of the cylinder 3 extends, pushing the connecting plate 9 to move along the slide bar towards the workpiece to be tested. The connecting plate 9 drives the clamping plates 5 to move synchronously through the T-shaped block groove 10, so that the two clamping plates 5 gradually approach the workpiece to be tested until they are clamped and tested. After the test is completed, the cylinder 3 is controlled to retract, and the output end of the cylinder 3 drives the connecting plate to move synchronously. 9 and clamping plate 5 move away from the test piece, causing clamping plate 5 to release the test piece. At this time, the test piece can be removed from the fixed support device. Then, when it is necessary to remove clamping plate 5, rotate the threaded sleeve 8. Since the threaded sleeve 8 and the threaded rod 15 are threadedly engaged, the threaded rod 15, driven by the threaded sleeve 8, drives the limiting block 13 to move in the opposite direction to the fixed block 6, and finally disengages from the second limiting block groove 16 of the fixed block 6, allowing the limiting block 13 to slide out of the second limiting block groove 16, releasing the lock on clamping plate 5. Then, pull clamping plate 5 to remove it from connecting plate 9. Through the mutual cooperation of the two limiting components on the upper surface of rotating seat 2, and the synchronous control of the extension and retraction of cylinder 3, reliable fixation of test pieces of different sizes can be achieved. At the same time, the rotation function of rotating seat 2 and the clamping and locking function of the limiting components are combined, so that the fixed support device can meet the testing requirements of multi-angle and multi-directional test pieces in high-pressure testing, improving testing efficiency and accuracy.

[0022] By rotating the threaded sleeve 8 in the limiting assembly, since the threaded sleeve 8 is threadedly engaged with the threaded rod 15, the threaded rod 15, driven by the threaded sleeve 8, drives the limiting block 13 to move in the opposite direction to the fixed block 6, and finally disengages from the second limiting block groove 16 of the fixed block 6, causing the limiting block 13 to slide out of the second limiting block groove 16, thus releasing the lock on the clamping plate 5. Then, pulling the clamping plate 5 can remove it from the connecting plate 9. This method of disassembling the clamping plate 5 is simple and quick, effectively improving the disassembly efficiency of the clamping plate 5, while reducing the workload of the operator.

By rotating the rotating threaded rod sleeve 8, the limiting block 13 can be driven to slide in the first limiting block groove 14 and the second limiting block groove 16, thereby locking or unlocking the clamping plate 5. Connecting plate 9: The connecting plate 9 is fixedly connected to the output end of the cylinder 3 and the slide rod, transmitting the power of the cylinder 3 to the clamping plate 5. At the same time, it cooperates with the T-block of the clamping plate 5 through the T-block groove 10, allowing the clamping plate 5 to be finely adjusted in the horizontal direction to adapt to the test piece of different sizes. Limiting block 13: The limiting block 13 is slidably connected to the second limiting block groove 16 of the rotating threaded rod 15 and the fixed block 6 respectively. Under the drive of the rotating threaded rod sleeve 8, it can slide into or out of the second limiting block groove 16 to lock or unlock the clamping plate 5 and improve the reliability of the fixed support device. Rotating threaded rod 15: One end of the rotating threaded rod 15 is fixedly connected to the limiting block 13, and the other end is threadedly connected to the rotating threaded rod sleeve 8, which converts the rotational motion of the rotating threaded rod sleeve 8 into the linear motion of the limiting block 13, thereby achieving mechanical locking of the clamping plate 5.
