Description

Technical Field

[0001] This utility model belongs to the field of angle steel testing technology, and in particular relates to a testing fixture assembly for testing the strength of angle steel. Background Technology

[0002] Angle steel (also known as angle iron) is a long strip of steel with two sides perpendicular to each other, belonging to carbon structural steel, and made from low-carbon square steel billets. Angle steel serves functions such as structural support, connection and fixation, and impact resistance, and its applications cover multiple fields including construction engineering, machinery manufacturing, power and transportation, decoration and home furnishing.

[0003] After the angle steel is produced and processed, its strength needs to be tested to ensure that the structural safety and performance of the angle steel meet the standards. At present, there are some strength testing structures on the market, such as a fixed tooling for angle steel strength monitoring published on the China Patent Network with the publication number CN221416352U. This tooling structure can be used for strength testing of angle steel, but there are some defects and deficiencies that need to be improved: (1) Due to structural design reasons, some existing tooling structures can only perform strength testing on a single angle steel. After each angle steel test is completed, the workpiece needs to be replaced, which is inefficient and difficult to meet the needs of large-scale angle steel strength testing. It also increases the workload of the testing personnel; (2) Most of the existing tooling structures adopt an integrated design. After long-term use, the related positioning and pressure components are prone to wear or deformation, making it difficult to disassemble and replace. This will not only affect the accuracy of the test results, but also shorten the service life of the tooling; (3) Some existing tooling structures lack effective protective measures. When the angle steel breaks during the strength testing process, it is easy to generate splashes, which poses a safety hazard and threatens the safety of the testing personnel. Therefore, the testing fixture assembly for angle steel strength testing provided by this utility model is of great significance in addressing the above problems. Utility Model Content

Multiple angle steels can be positioned using a positioning component, and a pressure applying mechanism can then be used to align and apply pressure to each angle steel, allowing for simultaneous strength testing of multiple angle steels without frequent workpiece changes. This significantly improves testing efficiency and effectively reduces the workload of testing personnel. Through modular design, worn or deformed positioning components and pressure applying mechanisms can be disassembled and replaced after prolonged use to avoid affecting the accuracy of test results and effectively extend the service life of the fixture. A protective cover can be placed around the angle steel during strength testing to effectively prevent flying debris from breaking and threatening the safety of testing personnel. In summary, this invention solves the problems in the prior art.

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-7 As shown, a testing fixture assembly for testing the strength of angle steel according to this utility model includes a base 1, a pair of adjustment grooves 2 on the top surface of the base 1, a positioning assembly on the base 1, a fixing frame 3 fixedly connected to the top of the base 1, a protective cover 4 installed on the front side of the fixing frame 3, a hydraulic cylinder 5 installed on the top of the fixing frame 3, a mounting seat 6 fixedly connected to the bottom end of the output shaft of the hydraulic cylinder 5, and a pressure applying mechanism installed at the bottom of the mounting seat 6.

[0033] The positioning assembly includes a first positioning seat 7 and a second positioning seat 8. The top surfaces of the first positioning seat 7 and the second positioning seat 8 are respectively provided with a plurality of first positioning grooves 9 and second positioning grooves 10. Both sides of the first positioning seat 7 and the second positioning seat 8 are fixedly connected with protrusions 11. The protrusions 11 are provided with threaded holes 12. The threaded holes 12 are threaded with bolts 13 that cooperate with them. When it is necessary to test the strength of the angle steel, the angle steel can be placed on the first positioning seat 7 and the second positioning seat 8, so that the two ends of the angle steel are respectively attached to the corresponding first positioning grooves 9 and second positioning grooves 10, so as to position the angle steel.

[0034] The pressure-applying mechanism includes a pressure plate 14, and several pressure blocks 15 are fixedly connected to the bottom of the pressure plate 14. By driving the hydraulic cylinder 5, the mounting base 6 and the entire pressure-applying mechanism can be moved downward together. When the pressure blocks 15 come into contact with the angle steel, pressure can be applied to the angle steel. At this time, the strength of the angle steel can be tested by observing the bending and deformation of the angle steel.

[0035] The number of first positioning grooves 9 and second positioning grooves 10 is the same, and they are equidistantly linearly distributed along the length direction of the first positioning seat 7 and the second positioning seat 8, respectively. The center of each first positioning groove 9 corresponds one-to-one with the center of each second positioning groove 10. When multiple angle steels are placed on the first positioning seat 7 and the second positioning seat 8, multiple angle steels can be positioned simultaneously through multiple first positioning grooves 9 and second positioning grooves 10, and they can be equidistantly distributed.

[0036] Both the first positioning groove 9 and the second positioning groove 10 are V-shaped with right angles at the bottom. Each first positioning groove 9 and second positioning groove 10 has an anti-slip pad 16 on its groove wall surface. The anti-slip pad 16 has herringbone anti-slip texture on its surface. The anti-slip pad 16 can be made of elastic materials such as rubber and is fixed by means of glue. When the two ends of the angle steel are attached to the first positioning groove 9 and the second positioning groove 10, the anti-slip texture on the surface of the anti-slip pad 16 can increase the friction between the angle steel and the first positioning groove 9 and the second positioning groove 10, so as to play an anti-slip role. This can effectively prevent the angle steel from slipping and shifting during the strength test, thus affecting the accuracy of the test results.

[0037] The adjusting groove 2 is rectangular, and its width corresponds to the diameter of the threaded hole 12. The center of each threaded hole 12 is located directly above the corresponding adjusting groove 2. By tightening the bolts 13 in each threaded hole 12, the bolts 13 can be screwed into the corresponding adjusting groove 2 until the bottom end of the bolt 13 is tightly against the bottom of the adjusting groove 2. At this time, the first positioning seat 7 and the second positioning seat 8 can be fixed to the base 1 through the mutual cooperation of the bolts 13 and the adjusting groove 2. When the first positioning groove 9 and the second positioning groove 10 are worn due to the pressure of the angle steel for a long time, the first positioning seat 7 and the second positioning seat 8 can be removed from the base 1 by unscrewing the bolts 13, so as to allow for the first positioning seat 7 and the second positioning seat 8 to be cleaned and repaired. For replacement, a guide block 17 is fixedly connected to the top of the base 1. The bottom of the first positioning seat 7 and the second positioning seat 8 are both provided with guide grooves 18. Both the guide grooves 18 and the guide block 17 are rectangular, and the width of the guide groove 18 is equal to the width of the guide block 17. The first positioning seat 7 and the second positioning seat 8 can move horizontally along the surface of the base 1 so as to adjust the distance between the first positioning seat 7 and the second positioning seat 8 according to the required length of the angle steel. The guide block 17 can be respectively attached to the guide groove 18 at the bottom of the first positioning seat 7 and the second positioning seat 8. Through the mutual cooperation between the guide block 17 and the guide groove 18, the first positioning seat 7 and the second positioning seat 8 can be limited so that they move in a straight line, thereby preventing them from deviating during movement.

[0038] The bottom of the pressure block 15 is V-shaped, and the number of them is the same as the number of the first positioning groove 9 and the second positioning groove 10. The center of each pressure block 15 corresponds one-to-one with the center of each first positioning groove 9 and the second positioning groove 10. When the angle steel is pressured by the pressure mechanism, each pressure block 15 can be aligned with multiple angle steels and pressure is applied, so that the strength of multiple angle steels can be tested at the same time without frequent replacement of workpieces. This not only greatly improves the testing efficiency, but also effectively reduces the workload of the testing personnel.

[0039] The pressure plate 14 is fixedly connected to both ends of the top with screws 19. Nuts 20 are threaded onto the screws 19 and mate with them. The mounting base 6 has a pair of mounting holes 21. The diameter of the mounting holes 21 corresponds to the diameter of the screws 19, and the center of each mounting hole 21 corresponds to the center of each screw 19. Each screw 19 can be aligned and passed through the corresponding mounting hole 21. The nuts 20 are then threaded onto each screw 19 and tightened. The pressure plate 14 is fixed by the mutual cooperation between the screws 19, the mounting holes 21, and the nuts 20. When the pressure block 15 is worn or deformed due to long-term use, the pressure plate 14 and the entire pressure mechanism can be removed from the mounting base 6 by unscrewing the nuts 20 for maintenance and replacement of the pressure block 15.

[0040] The protective cover 4 is rectangular, with its top opening sloping outwards. A buffer pad 22 is installed on the inner wall surface of the protective cover 4. During strength testing of the angle steel, the protective cover 4 can be placed over the angle steel to effectively prevent flying debris from the angle steel in the event of breakage, which could threaten the safety of the testing personnel. The buffer pad 22 can be made of elastic materials such as sponge and fixed with adhesive. The buffer pad 22 provides cushioning protection, preventing the angle steel from flying debris from directly contacting the inner wall of the protective cover 4 and causing deformation or breakage. The protective cover 4 is fixedly connected to a locking block 23 at its rear end. The locking block 23 is L-shaped. The bracket 24 is fixedly connected to the front end of the fixing frame 3. The cross-section of the bracket 24 is U-shaped. The length and width of its inner wall are equal to the width and thickness of the locking block 23, respectively. The locking block 23 can be inserted into and fit against the inner wall of the bracket 24. At this time, the protective cover 4 can be fixed on the fixing frame 3 by the cooperation of the locking block 23 and the bracket 24. The protective cover 4 can be removed from the fixing frame 3 by pulling out the locking block 23, so as to maintain and replace the protective cover 4.

[0041] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0042] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0043] The working principle of this utility model is as follows:

[0044] In use, this invention allows angle steel to be placed on the first positioning seat 7 and the second positioning seat 8, with both ends of the angle steel respectively fitting into the corresponding first positioning groove 9 and second positioning groove 10 for positioning. Then, the hydraulic cylinder 5 is driven to move the mounting seat 6 and the entire pressure-applying mechanism downwards. When the pressure block 15 contacts the angle steel, pressure is applied. The strength of the angle steel can be tested by observing its bending and deformation. When multiple angle steels are placed on the first positioning seat 7 and the second positioning seat 8, multiple first positioning grooves 9 and second positioning grooves 10 can simultaneously position multiple angle steels, ensuring they are evenly distributed. When pressure is applied to the angle steel by the pressure-applying mechanism, each pressure block 15 can be aligned with and apply pressure to multiple angle steels, thus simultaneously testing the strength of multiple angle steels. The inspection can be carried out without frequent workpiece replacement, which not only greatly improves the inspection efficiency, but also effectively reduces the workload of the inspection personnel. The front side of the fixed frame 3 is equipped with a protective cover 4 through the bracket 24. When the angle steel is subjected to strength testing, the protective cover 4 can cover the outside of the angle steel to effectively prevent the angle steel from breaking and causing splashes that threaten the safety of the inspection personnel. When the first positioning groove 9 and the second positioning groove 10 are worn due to the pressure of the angle steel for a long time, the first positioning seat 7 and the second positioning seat 8 can be removed from the base 1 by unscrewing the bolt 13 so that the first positioning seat 7 and the second positioning seat 8 can be replaced. When the pressure block 15 is worn or deformed due to long-term use, the pressure plate 14 and the entire pressure mechanism can be removed from the mounting base 6 by unscrewing the nut 20 so that the pressure block 15 can be maintained and replaced.
