Description

Technical Field

[0001] This utility model relates to the field of metal welded parts inspection, specifically a steel structure welding quality and compressive strength testing mechanism. Background Technology

[0002] Metal welded parts are parts or components formed by joining two or more metal materials together through welding processes. Metal welded parts are widely used in aerospace, automotive, machinery manufacturing, construction and other fields, and have important economic and social significance. Compression testing of metal welded parts is one of the important links in the quality inspection of metal welded parts. Compression testing usually refers to the test of measuring the compressive strength of metal welded parts under a certain pressure.

As a result, the steel structure may be displaced during the detection process, affecting the detection accuracy. At the same time, since the pressure is applied by a hydraulic rod, the pressure increase rate is unstable, which leads to inaccurate detection results. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a drive motor to rotate a drive gear, causing the sliders to move closer together, thus transferring energy and gradually transmitting the power of the drive motor to the sliders. This ensures the power source for subsequent clamping actions. When an interaction force is generated between the fixed column and the steel structure, the fixed spring contracts, thereby clamping and fixing steel structures of different shapes. This ensures that a stable clamping force can be provided on the surface of steel structures of different shapes, ensuring that the steel structure will not shift during subsequent testing, thereby guaranteeing the accuracy of the test results.

[0017] 2. This utility model, through the cooperation of components such as a motor, worm gear, worm ring, and threaded rod, realizes the lifting function of the detection structure. By controlling the rotation of the lifting motor and the drive worm ring, the detection structure is controlled to descend at a uniform speed, making the pressure increase rate stable. This allows for accurate acquisition of the steel structure's state under different pressures, facilitating accurate analysis of the steel structure's compressive strength limit. The pressure sensor on the fixed plate detects and records the pressure when the detection structure is pressed down, thus accurately recording the pressure data during the detection process. This facilitates the recording of the steel structure's compressive strength limit and provides crucial data support for subsequent detailed analysis of the steel structure's welding quality.

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.

[0026] Please see Figures 1-6 This utility model provides a technical solution for a steel structure welding quality compressive strength testing mechanism: A steel structure welding quality compressive strength testing mechanism includes a base plate 1, an installation structure 2 fixedly connected to the middle of the upper end face of the base plate 1, a driving structure 3 fixedly connected to the middle of the inner cavity of the installation structure 2, a clamping structure 4 symmetrically slidably connected to the inner cavity of the installation structure 2, a placement structure 5 fixedly connected to the left side of the upper end face of the base plate 1, a lifting structure 6 provided in the middle of the upper end face of the placement structure 5, a lifting driving structure 7 provided in the upper end face of the lifting structure 6, and a testing structure 8 provided in the lower end face of the lifting structure 6.

[0027] Furthermore, the mounting structure 2 includes a mounting plate 21 fixedly connected to the middle of the upper end face of the base plate 1. A mounting groove 22 is provided in the middle of the upper end face of the mounting plate 21. Rotating rods 23 are rotatably connected to the left and right sides of the inner cavity of the mounting groove 22. A transmission gear 24 is fixedly connected to the middle of the outer surface of the rotating rod 23. Two sections of threads with opposite directions are respectively provided on the outer surface of the rotating rod 23 on the front and rear sides of the transmission gear 24. A drive structure 3 is provided in the inner cavity of the mounting groove 22 between the two transmission gears 24.

[0028] Furthermore, the drive structure 3 includes a drive motor 31 fixedly connected to the middle of the lower end face of the inner cavity of the rotating rod 23. A drive gear 32 is fixedly connected to the output end of the drive motor 31. A toothed belt 33 is connected to the outer surface of the transmission gear 24. The drive gear 32 is meshed in the middle of the inner cavity of the toothed belt 33.

[0029] Furthermore, the clamping structure 4 includes sliders 41 symmetrically slidably connected to the inner cavity of the mounting groove 22, a rotating rod 23 passing through the sliders 41 and threadedly connected, clamping plates 42 fixedly connected to the upper end faces of two adjacent sliders 41, and fixing structures 43 fixedly connected to the front and rear end faces of the two clamping plates 42. The fixing structures 43 are installed and placed by the clamping plates 42, and then the clamping plates 42 and the fixing structures 43 slide relative to each other by the movement of the sliders 41, and the fixing column 434 contacts the steel structure.

[0030] Furthermore, the fixing structure 43 includes fixing blocks 431 fixedly connected to the front and rear sides of the base plate 1 between the two clamping plates 42. Sliding grooves 432 are evenly provided on the front and rear end faces of the two fixing blocks 431. A fixing spring 433 is fixedly connected to the side of the inner cavity of the sliding groove 432 near the clamping plate 42. A fixing column 434 is slidably connected to the inner cavity of the sliding groove 432. The end of the fixing spring 433 away from the sliding groove 432 is fixedly connected to the fixing column 434. The placement structure 5 includes a placement column 51 fixedly connected to the left side of the upper end face of the base plate 1. A placement plate 52 is fixedly connected to the upper end face of the placement column 51. A lifting structure 6 is provided in the middle of the upper end face of the placement plate 52. By retracting the fixing spring 433, steel structures of different shapes can be clamped and fixed to ensure that the steel structure will not be displaced during subsequent testing, thereby ensuring the accuracy of the test results.

[0031] Furthermore, the lifting structure 6 includes a connecting ring 61 fixedly connected to the middle of the upper end face of the placement plate 52. The connecting ring 61 passes through the placement plate 52. Limiting blocks 62 are uniformly fixedly connected to the inner side wall of the connecting ring 61. A threaded rod 63 is slidably connected to the inner cavity of the connecting ring 61. The outer surface of the threaded rod 63 is uniformly provided with grooves that match the limiting blocks 62. A detection structure 8 is fixedly connected to the lower end face of the threaded rod 63. Through the lifting structure 6 on the placement structure 5, the detection structure 8 and the lifting drive structure 7 are installed and placed during use, and the threaded rod 63 is raised and lowered by the limiting blocks 62.

[0032] Furthermore, the lifting drive structure 7 includes a drive worm ring 71 rotatably connected to the upper end face of the connecting ring 61. The inner cavity of the drive worm ring 71 is threadedly connected to the threaded rod 63. The upper end face of the placement plate 52 is located on one side of the drive worm ring 71 and is rotatably connected to the worm 72 via a bracket. The upper end face of the placement plate 52 is located on one side of the worm 72 and is fixedly connected to the lifting motor 73. The drive worm ring 71 and the worm 72 mesh with each other. The rotating shaft of the front end face of the worm 72 passes through the bracket and is fixedly connected to the output end of the lifting motor 73. By controlling the rotation of the lifting motor 73 and the drive worm ring 71, the detection structure 8 is controlled to achieve uniform descent, so that the pressure enhancement rate is stable. In this way, the stable pressure enhancement rate can more accurately obtain the state of the steel structure under different pressures, which is convenient for accurately analyzing the compressive strength limit of the steel structure.

[0033] Furthermore, the detection structure 8 includes a fixing plate 81 fixedly connected to the lower end face of the threaded rod 63. A pressure sensor 82 is fixedly connected to the middle of the lower end face of the fixing plate 81, and a pressing plate 83 is fixedly connected to the lower end face of the pressure sensor 82. The pressure sensor 82 on the fixing plate 81 detects and records the pressure when the detection structure 8 is pressed down, which facilitates the personnel to detect and record the compressive strength limit of the steel structure and provides key data support for subsequent detailed analysis of the welding quality of the steel structure.

[0034] Working principle: During operation, the steel structure is placed between two fixed structures 43. The drive structure 3 is then activated, causing the output of the drive motor 31 to rotate. This drives the gear 32, which in turn rotates the toothed belt 33. Since the toothed belt 33 is connected to the transmission gear 24, the transmission gear 24 rotates, further causing the rotating rod 23 to rotate. This causes the sliders 41 to move closer together, resulting in relative sliding between the clamping plate 42 and the fixed structures 43. This brings the fixed column 434 into contact with the steel structure. Due to the interaction force between the fixed column 434 and the steel structure, the fixed column 434 in contact with the steel structure slides into the inner cavity of the sliding groove 432, causing the fixing spring 433 to contract. This clamps and fixes steel structures of different shapes.

[0035] When welding quality inspection is required, the lifting drive structure 7 is activated, causing the output end of the lifting motor 73 to rotate. This causes the worm gear 72 to rotate. Since the worm gear 72 meshes with the drive worm ring 71, the drive worm ring 71 rotates. Because the drive worm ring 71 is threadedly connected to the threaded rod 63, the threaded rod 63 rotates. However, because the inner cavity of the connecting ring 61 is fixedly connected to the limiting block 62, which slides through the limiting groove on the outer surface of the threaded rod 63, the threaded rod 63 slides up and down. At this time, by controlling the rotation of the lifting motor 73 and the drive worm ring 71, the operator makes the inspection structure 8 descend at a uniform speed, thus stabilizing the pressure increase rate.

[0036] Meanwhile, the pressure sensor 82 on the fixed plate 81 detects and records the pressure when the detection structure 8 is pressed down, which makes it convenient for personnel to detect and record the compressive strength limit of the steel structure.

[0037] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
