Description

Technical Field

[0001] This utility model belongs to the field of metal component strength testing technology, and in particular relates to a metal component strength testing device. Background Technology

[0002] Metal components refer to various parts or assemblies made of metal materials. They play a key role in various equipment and machinery. After the metal components are manufactured and processed, their strength needs to be tested to ensure the quality of the product. Nowadays, the common method is to apply pressure to the metal components and observe the changes in the metal components after a certain pressure is applied to determine whether they are qualified.

[0003] Chinese patent discloses a metal strength testing device, publication number CN212989063U. The device includes a testing box, with a load-bearing plate fixedly connected to the inner sidewalls of the testing box. A symmetrical upright plate is fixedly connected to the upper surface of the load-bearing plate. The top of each upright plate is fixedly connected to the inner top wall of the testing box. A groove is formed on one side of each upright plate that is close to each other. A slider is provided inside each groove. A sliding plate is fixedly connected to one side of each slider that is close to each other. A testing pressure block is fixedly connected to the bottom surface of the sliding plate. This metal strength testing device transmits pressure data to a testing panel for display, achieving the effect of testing metal strength. It avoids the problem of low accuracy in metal testing, provides greater stability to the first pad during movement, and solves the problem of not being able to support metals of different sizes.

[0019] 2. By engaging the mounting block with the slot and utilizing the elasticity of the mounting spring, the mounting block can be engaged with or disengaged from the mounting hole, thus enabling quick assembly and disassembly between the detection disc and the mounting base. This facilitates the disassembly and replacement of severely worn or damaged detection discs, reduces the difficulty of disassembling and assembling detection discs using traditional bolt fixing, and improves the efficiency of maintenance or replacement work.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] Example 1

[0029] A preferred embodiment of the metal component strength testing device provided by this utility model is, for example... Figures 1 to 5As shown: A metal component strength testing device includes a body 6; a controller 8 fixedly connected to the upper end of one side of the body 6; viewing doors 3 fixedly connected to both sides of the front of the body 6 via hinges; a hydraulic cylinder 1 fixedly connected to the middle position of the top of the body 6, the output end of the hydraulic cylinder 1 extending into the interior of the body 6 and fixedly connected to a sliding seat 2; a pressure sensor 18 fixedly connected to the bottom end of the sliding seat 2; a mounting base 17 fixedly connected to the bottom end of the pressure sensor 18; a detection plate 10 provided at the bottom end of the mounting base 17; and a mounting assembly 9 assembled on the mounting base 17, the mounting assembly 9 being used to realize the separation between the detection plate 10 and the mounting base 17. The machine body 6 is equipped with a fixed frame 4, which is fixedly connected to the bottom wall of the machine body 6. A fixed groove 14 is opened at the middle position of the top of the fixed frame 4. Limiting grooves 13 are opened at the top of the fixed frame 4 at both ends of the fixed groove 14. Clamping seats 11 are provided on both sides of the top of the fixed frame 4. Pneumatic telescopic rods 12 are fixedly connected to both ends of the top of the clamping seats 11. The output end of the pneumatic telescopic rods 12 extends into the interior of the clamping seats 11 and is fixedly connected to a pressure plate 16. A clamping assembly 7 is assembled inside the fixed frame 4. The clamping assembly 7 is used to realize the sliding adjustment of the clamping seats 11. A collection assembly 5 is assembled on the bottom wall of the fixed frame 4. The collection assembly 5 is used to collect the crushed debris.

[0030] The collection component 5 includes: slid grooves 505 symmetrically opened on the lower ends of both sides of the inner wall of the fixed frame 4; a collection hopper 501 disposed inside the fixed frame 4, with slide plates 502 fixedly connected to both sides of the collection hopper 501 and a card plate 503 fixedly connected to the front of the collection hopper 501; and a rotating plate 504 rotatably connected to the middle position of the upper end of the front of the fixed frame 4.

[0031] It should be noted that some existing metal component strength testing devices still have certain shortcomings in actual use. When the metal components in the comparison documents break, small fragments fall into the cavity, making it inconvenient for subsequent staff to clean them. At the same time, too many fragments can also affect the transmission effect of the threaded rod, which in turn makes it difficult to support and limit the metal components, affecting subsequent testing operations.

[0032] In this embodiment, the clamping assembly 7 is used to slide the two clamping seats 11 to clamp and fix the metal component sample. Then, the pneumatic telescopic rod 12 is activated, causing the pressure plate 16 to press and fix the top of the metal component sample, thus achieving firm clamping and pressing of metal component samples of different sizes. Then, the door on the viewing door 3 is closed, and the hydraulic cylinder 1 is activated to lower the sliding seat 2, the mounting seat 17, and the detection plate 10, thereby causing the bottom of the detection plate 10 to apply pressure to the top of the metal component sample. The pressure sensor 18 detects the pressure in real time and displays it on the display screen on the controller 8. When the test pressure reaches a certain value, if the metal component sample does not bend, it means that the sample is qualified. When the metal component sample bends, the pressure sensor 18 detects... If the pressure does not meet the standard, it means that the sample is unqualified. If the sample is unqualified and is accidentally broken during testing, the closed space formed by the viewing door 3 and the machine body 6 is used to avoid the safety hazards caused by the debris flying too far. Some debris will fall into the collection hopper 501 through the limiting groove 13 and the fixing groove 14, realizing the automatic collection of debris. The positive and negative threaded rods 701 are set in the reserved groove 704, which can effectively prevent debris from accumulating and causing the thread transmission of the positive and negative threaded rods 701 to be unobstructed. After the testing operation is completed, the viewing door 3 can be opened, and the rotating plate 504 can be rotated to separate from the clamping plate 503. Then, the staff can slide the collection hopper 501 out through the clamping plate 503 for centralized processing of the debris collected inside the collection hopper 501.

[0033] In a further preferred embodiment of the present invention, the upper ends of both sides of the inner wall of the collecting hopper 501 are inclined, and the two sides of the collecting hopper 501 form a sliding structure between the sliding plate 502 and the interior of the sliding groove 505.

[0034] In this embodiment, the collection hopper 501 with its inclined inner wall allows debris to be discharged more easily and smoothly into the interior of the collection hopper 501.

[0035] In a further preferred embodiment of the present invention, the card plate 503 is inverted L-shaped, and the inner wall of the card plate 503 and the rotating plate 504 form an engaging structure.

[0036] In this embodiment, an inverted L-shaped locking plate 503 is used so that it can be rotated and engaged with the rotating plate 504, and can also be used as a handle to pull the collection hopper 501 to slide.

[0037] In a further preferred embodiment of the present invention, the clamping assembly 7 includes: a reserved slot 704 formed at one end of the inner wall of the fixing frame 4; a servo motor 705 fixedly connected to one side of the fixing frame 4, the output end of the servo motor 705 extending into the interior of the reserved slot 704 and fixedly connected to a positive and negative threaded rod 701 via a coupling; and threaded seats 703 symmetrically threaded on both sides of the surface of the positive and negative threaded rod 701, the top end of the threaded seats 703 being fixedly connected to the bottom end of the clamping seat 11.

[0038] In this embodiment, the servo motor 705 is started to drive the positive and negative threaded rod 701 to rotate. The threaded engagement between the positive and negative threaded rod 701 and the threaded seat 703 causes the threaded seat 703 to slide, thereby driving the two clamping seats 11 to slide, which facilitates the clamping and fixing of the metal part sample.

[0039] In a further preferred embodiment of the present invention, the threaded seat 703 has through grooves at both ends, and the inner wall of the fixing bracket 4 is fixedly connected with a slide rod 702 that slides in cooperation with the through grooves.

[0040] In this embodiment, the smoothness of the sliding adjustment of the threaded seat 703 is improved by utilizing the sliding between the slide rod 702 and the threaded seat 703.

[0041] In a further preferred embodiment of the present invention, the threaded seat 703 is mountain-shaped, and the upper end of the threaded seat 703 forms a sliding structure with the interior of the limiting groove 13 and the fixing groove 14.

[0042] In this embodiment, the sliding of the mountain-shaped threaded seat 703 with the limiting groove 13 and the fixing groove 14 is used to improve the stability of the clamping seat 11 during sliding.

[0043] In a further preferred embodiment of the present invention, the bottom end of the pressing plate 16 is provided with anti-slip textures 15 at equal intervals, and the shape of the anti-slip textures 15 is an isosceles trapezoid.

[0044] In this embodiment, the anti-slip texture 15 of the isosceles trapezoid is used to improve the anti-slip performance of the bottom end of the pressing plate 16 and the top end of the metal component sample when pressed together.

[0045] Example 2

[0046] Based on Embodiment 1, a preferred embodiment of the metal component strength testing device provided by this utility model is as follows: Figures 1 to 5As shown: The mounting component 9 includes: a slot 901 formed at the bottom of the mounting base 17, and a mounting groove 907 formed at the lower end of the interior of the mounting base 17 on one side of the slot 901; a mounting block 904 slidably connected inside the mounting groove 907, one end of the mounting block 904 extending into the interior of the slot 901, and the other end of the mounting block 904 being fixedly connected to a pull rod 906 extending to the outside of the mounting base 17; a mounting spring 905 wrapped around the surface of the pull rod 906, with both ends of the mounting spring 905 being fixedly connected to one side of the mounting block 904 and the inner wall of the mounting groove 907 respectively; and a locking block 902 fixedly connected to the top of the detection plate 10, with a mounting hole 903 formed at the lower end of one side of the locking block 902.

[0047] In this embodiment, by pulling the lever 906, the mounting block 904 is slidably compressed and the mounting spring 905 is completely disengaged from the mounting hole 903. Then, the detection disc 10 is pulled, causing the locking block 902 to completely slide away from the slot 901, thus disassembling the detection disc 10. During installation, the lever 906 is first pulled, causing the mounting block 904 to slide completely into the mounting groove 907. Then, the locking block 902 is locked into the slot 901. After releasing the lever 906, the elastic force of the mounting spring 905 is used to make the mounting block 904 slide into the mounting hole 903, thus achieving a firm engagement between the locking block 902 and the slot 901.

[0048] In a further preferred embodiment of the present invention, the card block 902 and the card slot 901 form an engaging structure, and the card slot 901 and the card block 902 are convex in shape.

[0049] In this embodiment, the engagement between the inverted convex locking block 902 and the slot 901 is used to improve the initial engagement strength between the detection disk 10 and the mounting base 17.

[0050] In a further preferred embodiment of the present invention, one end of the mounting block 904 and the interior of the mounting hole 903 form an engaging structure, and the length of the mounting block 904 is less than the depth of the mounting groove 907.

[0051] In this embodiment, the engagement of one end of the mounting block 904 with the inside of the mounting hole 903 prevents the locking block 902 from accidentally disengaging from the inside of the slot 901.

[0052] In summary, the collection component 5 facilitates the collection of broken fragments, the clamping component 7 clamps the metal component sample, and the pressure plate 16 presses the top of the metal component sample to achieve a firm clamping and fixing of metal component samples of different sizes. At the same time, the installation component 9 enables the quick disassembly and assembly of the detection disc 10, facilitating its maintenance or replacement.
