[0001] This utility model relates to a multi-aperture adapter plate for insulator bending resistance testing, belonging to the field of power equipment testing tooling technology. Background Technology

[0002] In the mechanical performance testing of insulators, the bending test is one of the important testing items. In existing technology, the fixture plates for insulator bending tests are usually designed with a single aperture, which can only accommodate insulators with a fixed mounting hole diameter, resulting in poor versatility. When testing insulators with different mounting hole diameters is required, the corresponding fixture plate must be changed, which is not only cumbersome and inefficient but also increases testing costs. Furthermore, frequent fixture changes can lead to positioning errors in the testing equipment, affecting the accuracy of the test. Therefore, there is an urgent need for a universal fixture plate that can adapt to multiple mounting hole diameters to solve the above problems. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a multi-specification mounting hole diameter adapter plate for insulator bending resistance testing, which addresses the shortcomings of existing technologies. This solves the problems of poor versatility and low testing efficiency of existing tooling plates, and enables adaptation to insulators with different mounting hole diameters, thereby improving the convenience and accuracy of testing.

[0004] To solve this technical problem, this utility model provides a multi-specification mounting hole diameter fixture plate for insulator bending resistance testing, including a fixture plate body, an adjusting slider, and a positioning ear plate. The fixture plate body is a circular plate, including a radial groove, a mounting hole, a positioning ear plate mounting hole, and a central positioning hole. The radial groove is radially distributed. The adjusting slider is inserted into the radial groove from the outer edge opening of the radial groove and can slide radially along the radial groove. The positioning ear plate is set on the edge of the radial groove on the fixture plate body and is fastened to the fixture plate body with bolts through the positioning ear plate mounting hole. The adjusting slider includes an adjusting slider body, which is provided with at least one set of mounting hole groups. Each set of mounting hole groups contains multiple mounting holes of different diameters, and the diameter of the mounting holes covers the range of common mounting hole diameters for insulators.

[0005] The radial grooves are evenly distributed in eight groups along the radial direction on the circular plate, each group being 50mm wide and 500mm long.

[0006] The tooling plate is a circular plate made of high-strength alloy steel, with a diameter of 1200mm and a thickness of 40mm.

[0007] The first mounting hole consists of 16 holes with a diameter of 26mm, evenly distributed along the outer edge of the circular plate. The tooling plate is fastened to the bending device with bolts through the first mounting hole.

[0008] The mounting holes of the positioning ear plate are M12 threaded holes, and there are eight sets evenly distributed on the outer edge of the tooling plate body, which are consistent with the distribution angle of the eight sets of radial sliding grooves.

[0009] The central positioning hole is a 50mm diameter hole with a copper wear-resistant bushing embedded in its inner wall.

[0010] The adjusting slider also includes an adjusting slider locking countersunk hole, which is a countersunk hole for installing an M16 hexagonal locking bolt.

[0011] The adjusting slider is made of high-strength alloy steel.

[0012] The positioning ear plate is made of high-strength alloy steel plate and includes a positioning ear plate body and a second mounting hole, which is a hole with a diameter of 14mm.

[0013] The mounting hole group has five mounting holes with diameters of M12, M16, M20, M24 and M30 respectively, and the diameter difference between adjacent mounting holes is 4mm to 6mm.

[0014] Beneficial effects: This utility model has strong versatility: Through the radially adjustable adjusting arm and multiple sets of mounting holes with different diameters, it can adapt to the mounting hole diameters of various specifications of insulators, eliminating the need for frequent tooling plate replacements; Precise positioning: The central positioning hole cooperates with the positioning mechanism of the testing equipment to ensure the coaxiality of the insulator during the test, improving the accuracy of the bending test; High installation efficiency: Only the position of the adjusting arm needs to be adjusted and the corresponding mounting hole set needs to be selected to complete the installation preparation of different insulators, significantly reducing tooling adjustment time; Stable structure: The radial adjusting arm and the sliding locking structure of the tooling plate body are adopted to ensure the stability and installation accuracy of the tooling plate during the installation process; Reduced cost: One set of tooling plates can replace multiple sets of special tooling, significantly reducing tooling procurement and management costs.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] like Figures 1-4 As shown, this utility model provides a multi-specification mounting hole diameter fixture plate for insulator bending resistance testing, including a fixture plate body 1, an adjusting slider 2, and a positioning ear plate 3. The fixture plate body 1 is a circular plate, including a radial groove 11, a mounting hole 12, a positioning ear plate mounting hole 13, and a central positioning hole 14. The radial groove 11 is radially distributed. The adjusting slider 2 is inserted into the radial groove 11 from the outer edge opening of the radial groove 11. The adjusting slider 2 can slide radially along the radial groove 11 and is locked in position by a locking bolt. The positioning ear plate 3 is set on the edge of the radial groove 11 on the fixture plate body 1 and is fastened to the fixture plate body 1 by bolts through the positioning ear plate mounting hole 13. The adjusting slider 2 includes an adjusting slider body 21, which is provided with at least one set of mounting hole groups 22. Each set of mounting hole groups 22 includes multiple mounting holes of different diameters, and the diameter of the mounting holes covers the range of common mounting hole diameters for insulators.

[0019] The radial grooves 11 are evenly distributed in eight groups along the radial direction on the circular plate, each group being 50mm wide and 500mm long.

[0020] The tooling plate body 1 is a circular plate made of high-strength alloy steel, with a diameter of 1200mm and a thickness of 40mm.

[0021] The mounting hole 12 consists of 16 holes with a diameter of 26mm, evenly distributed along the outer edge of the circular plate. The tooling plate is fastened to the bending device with bolts through the mounting hole 12.

[0022] The positioning ear plate mounting holes 13 are M12 threaded holes, and are set on the outer edge of the tooling plate body 1. There are eight sets evenly distributed, and the angles are consistent with the distribution angles of the eight sets of radial grooves 11.

[0023] The central positioning hole 14 is a 50mm diameter hole used to cooperate with the positioning mechanism of the bending test equipment to achieve coaxial positioning. The inner wall of the central positioning hole 14 is embedded with a copper wear-resistant bushing to ensure positioning accuracy after long-term use.

[0024] The adjusting slider 2 also includes an adjusting slider locking countersunk hole 23, which is a countersunk hole for installing an M16 hexagonal locking bolt.

[0025] The adjusting slider 2 is made of high-strength alloy steel.

[0026] The positioning ear plate 3 is made of high-strength alloy steel plate and includes a positioning ear plate body 31 and a second mounting hole 32. The second mounting hole 32 is a hole with a diameter of 14mm, which is used to adjust the disassembly, assembly and limiting of the slider 2.

[0027] The mounting hole group 22 has five mounting holes with diameters of M12, M16, M20, M24 and M30 respectively. The diameter difference between adjacent mounting holes is 4mm to 6mm to accommodate the mounting hole requirements of insulators of different specifications.

[0028] The assembly process using this utility model is as follows: Tooling positioning: First, the tooling plate is aligned with the positioning shaft of the bending equipment through the center positioning hole 14. Then, the tooling plate is fastened to the bending equipment with bolts through the mounting hole 12.

[0029] Adjusting slider entry: After the tooling plate body 1 and the bending device are installed, the adjusting slider 2 is inserted into the radial groove from the outer edge opening of the radial groove 11 on the tooling plate body 1. Then, the positioning ear plate 3 is fastened to the positioning ear plate mounting hole 13 on the tooling plate body 1 through the mounting hole 2 32 with bolts for the disassembly, assembly and limiting of the slider.

[0030] Adjusting the slider: According to the position of the mounting hole group 22 corresponding to the mounting hole diameter of the insulator to be installed, loosen the locking bolt on the adjusting slider 2 installed on the adjusting slider locking countersunk hole 23, and adjust the adjusting slider 2 along the radial slide groove 11 on the tooling plate body 1 so that the target mounting hole on the mounting hole group 22 is aligned with the mounting hole diameter of the insulator to be installed. Then tighten the locking bolt on the adjusting slider locking countersunk hole 23 to lock the adjusting slider 2. Insulator installation: Align the mounting end of the insulator with the target mounting hole on the adjusted mounting hole group 22, insert the mounting bolt and tighten it to complete the insulator installation.

[0031] Tooling plate switching: When it is necessary to install insulators with different hole diameters, repeat steps 2 and 3, adjust the position of the adjusting slider 2 and select the target mounting hole of the corresponding mounting hole group 22; there is no need to change the tooling plate.

[0032] This invention, through its radially adjustable adjusting arm and multiple sets of mounting holes with different diameters, can adapt to the mounting hole diameters of various insulator specifications, eliminating the need for frequent tooling plate replacements and offering strong versatility. The central positioning hole, in conjunction with the positioning mechanism of the testing equipment, ensures the coaxiality of the insulator during the test, improving the accuracy of the bending test and ensuring precise positioning. The installation preparation for different insulators can be completed simply by adjusting the position of the adjusting arm and selecting the corresponding mounting hole set, significantly reducing tooling adjustment time and increasing installation efficiency. The radial adjusting arm and the sliding locking structure of the tooling plate body ensure the stability and installation accuracy of the tooling plate during installation, resulting in structural stability. One set of tooling plates can replace multiple sets of dedicated tooling, significantly reducing tooling procurement and management costs.

[0033] This invention combines a radial adjustable arm with a multi-diameter mounting hole assembly to achieve compatibility with mounting hole diameters of insulators of different specifications. It solves the problem of poor versatility of traditional tooling plates, significantly improves the efficiency and economy of insulator installation, and has high practical value and promotional significance.
