Description

Technical Field

[0001] This utility model relates to the field of materials testing technology, and in particular to a strength testing device for alloy material workpieces. Background Technology

[0002] Alloy material workpieces refer to mechanical parts or structural components made of materials composed of multiple metallic elements. They possess excellent mechanical properties, corrosion resistance, and high-temperature strength, and are widely used in demanding fields such as aerospace, automotive manufacturing, and construction engineering. Because they bear crucial load-bearing functions in various key equipment and structures, strength testing of alloy material workpieces is particularly important. Strength testing not only relates to product performance and service life but is also a fundamental step in ensuring the safety and reliability of the overall structure.

[0003] Existing strength testing devices typically employ single-point detection. For example, utility model patent CN220339879U discloses a strength testing device for alloy material workpieces, relating to the field of workpiece strength testing equipment. This device includes a base, a first clamping component, a hydraulic rod, a top frame, a second clamping component, a back plate, and a photoelectric ranging probe. By incorporating the photoelectric ranging probe, hydraulic rod, and top frame, this device can detect the diameter change of the alloy material during tensile testing in real time and transmit the data to a receiver, thus achieving relatively accurate data acquisition. However, in practical applications, it has been found that while this device can improve detection accuracy to some extent, it can only detect and observe tensile force data on one side of the alloy material, failing to comprehensively detect all four sides. This results in biased test data that fails to accurately reflect the overall stress state and deformation of the material. This limitation not only affects the comprehensiveness and reliability of the test results but also restricts its application in high-end manufacturing for evaluating material performance under complex working conditions.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a strength testing device for alloy material workpieces to solve this problem. This testing device should be able to simultaneously inspect alloy material workpieces from multiple angles and directions, significantly improving testing efficiency and data comprehensiveness. Simultaneously, it should better meet the modern production demands for high-precision, multi-dimensional testing, providing strong technical support for the application of alloy materials in high-performance fields. Utility Model Content

[0005] The purpose of this invention is to provide a strength testing device for alloy material workpieces, which solves the problem that the existing technology can only detect and observe tensile force data on one side of the alloy material, and cannot conduct comprehensive testing on all four sides of the alloy material, resulting in one-sided test data that is difficult to truly reflect the overall stress state and deformation of the material.

[0006] To achieve the above objectives, this utility model provides a strength testing device for alloy material workpieces, including a base and a top plate. The top plate is connected to the top of the base through several support rods. A lifting plate is provided at the bottom of the top plate. The top of the lifting plate is connected to the top of the top plate through a lifting structure.

[0007] A rotating ring is connected to the top center of the base, a lifting frame is connected to the top of the rotating ring, a lifting block is slidably connected inside the lifting frame, and an optical ranging probe and a receiver are connected to one side of the lifting block.

[0009] The rotating ring has a rotating base rotatably connected to the bottom of the base and the top of the base. The lifting structure includes a lifting cylinder installed on the top of the top plate, and the output end of the lifting cylinder is connected to the top of the lifting plate.

[0010] The lifting and adjusting structure includes a lead screw rotatably connected inside the lifting frame and a second drive motor installed on the top of the lifting frame. The output shaft of the second drive motor is connected to the end of the lead screw, and the lifting block is threadedly engaged with the lead screw.

[0011] The rotating base has an outer ring fitted with a mounting ring, which is fixedly connected to the top of the base with bolts.

[0012] The lifting frame has sliding grooves on both sides that communicate with the interior, and the lifting block has sliders fixedly connected to both sides that cooperate with the sliding grooves.

[0013] The drive assembly includes a driven gear disk and a driving gear disk disposed on the outer ring of the rotating ring. The driving gear disk is rotatably connected to the top side of the base, and the driving gear disk is meshed with the driven gear disk through a snap ring.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, an alloy material workpiece strength testing device of this embodiment includes a base 1 and a top plate 3. The top plate 3 is connected to the top of the base 1 by a number of support rods. A lifting plate 2 is provided at the bottom of the top plate 3. The top of the lifting plate 2 is connected to the top of the top plate 3 by a lifting structure. Clamping parts 6 are connected to the sides of the lifting plate 2 and the base 1 that are close to each other.

[0025] A rotating ring 12 is connected to the top center of the base 1, a lifting frame 5 is connected to the top of the rotating ring 12, a lifting block 17 is slidably connected inside the lifting frame 5, and an optical ranging probe 16 and a receiver 15 are connected to one side of the lifting block 17.

[0026] The lifting block 17 is connected to the top of the lifting frame 5 through a lifting adjustment structure, and a drive component for driving the rotating ring 12 to rotate is provided on one side of the top of the base 1.

[0027] The workflow is as follows: Before testing, the alloy material workpiece to be tested is placed between the clamping parts 6 on the base 1, and the workpiece is firmly clamped by the clamping parts 6 on both sides to ensure that there is no displacement or slippage during the test. Then, the lifting structure is activated, which drives the lifting plate 2 below the top plate 3 to move downward, so that the clamping parts 6 above apply tensile force to the workpiece, simulating the stress state of the material in actual use. At the same time, the rotating ring 12 at the top center of the base 1 drives the lifting frame 5 to rotate under the action of the drive component, so that the entire lifting frame 5 moves in a circle around the workpiece. The lifting block 17, which is slidably connected inside the lifting frame 5, can be adjusted up and down according to the height change of the workpiece to keep the relative position of the photoelectric ranging probe 16 and the workpiece surface stable. The photoelectric ranging probe 16 works with the receiver 15 to collect the deformation data of the workpiece at different angles during the stress process in real time, and transmits these data to the control system for analysis. In addition, the lifting block 17 is connected to the top of the lifting frame 5 through the lifting adjustment structure, and can adjust its own height as needed during the test, so as to achieve accurate measurement of different parts of the workpiece, and thus complete the multi-directional and multi-angle synchronous detection task.

[0028] Example 2

[0029] Please see Figure 1-5 As shown in this embodiment, an alloy material workpiece strength testing device has a rotating base 7 rotatably connected to the bottom of the rotating ring 12 and connected to the top of the base 1. The lifting structure includes a lifting cylinder 4 installed on the top of the top plate 3. The output end of the lifting cylinder 4 is connected to the top of the lifting plate 2. Specifically, through the connection between the rotating base 7 at the bottom of the rotating ring 12 and the top of the base 1, and the cooperation between the lifting cylinder 4 installed on the top of the top plate 3 and the lifting plate 2, during the test, the lifting cylinder 4 can drive the lifting plate 2 to move up and down along the support rod direction, thereby driving the clamping member 6 to apply tensile force to the workpiece; at the same time, the rotating base 7 supports the rotating ring 12 to rotate stably, ensuring that the lifting frame 5 and the photoelectric ranging probe 16 operate smoothly when they move in a circle around the workpiece; thus achieving the effect of improving loading accuracy and measurement stability, and enhancing the overall structural load-bearing capacity.

[0030] The outer ring of the rotating base 7 is fitted with a mounting ring 10, which is bolted to the top of the base 1. Specifically, by bolting the mounting ring 10 fitted on the outer ring of the rotating base 7 to the top of the base 1, the rotating ring 12 and its upper structure can be stably installed on the main body of the equipment. When maintenance or replacement of parts is required, the parts can be quickly separated by removing the bolts. This not only enhances the overall structural stability of the equipment, but also improves the maintainability and future expandability of the device, making it convenient for daily use and maintenance.

[0031] The drive assembly includes a driven gear disk 11 and a driving gear disk 9 disposed on the outer ring of the rotating ring 12. The driving gear disk 9 is rotatably connected to the top side of the base 1, and the driving gear disk 9 is meshed with the driven gear disk 11 through a snap ring. A drive motor 8 is installed on the bottom side of the base 1 to cooperate with the driving gear disk 9. Specifically, through the meshing transmission between the driving gear disk 9 and the driven gear disk 11 in the drive assembly, and the linkage between the drive motor 8 and the driving gear disk 9, during the test, after the drive motor 8 starts, it drives the driving gear disk 9 to rotate, and then drives the driven gear disk 11 and the rotating ring 12 to rotate through gear meshing. This achieves precise control of the lifting frame 5 and the photoelectric ranging probe 16 scanning the workpiece from multiple angles; it achieves the purpose of improving the rotation drive efficiency, realizing multi-directional continuous detection, and enhancing the automation level and test integrity of the equipment.

[0032] Example 3

[0033] Please see Figure 1-5 As shown in the figure, the alloy material workpiece strength testing device of this embodiment includes a lifting adjustment structure comprising a lead screw 14 rotatably connected inside the lifting frame 5 and a second drive motor 13 installed on the top of the lifting frame 5. The output shaft of the second drive motor 13 is connected to the end of the lead screw 14. The lifting block 17 is threadedly engaged with the lead screw 14. Specifically, through the threaded engagement between the second drive motor 13, the lead screw 14 and the lifting block 17 in the lifting adjustment structure, during the test, after the second drive motor 13 starts, it drives the lead screw 14 to rotate, causing the lifting block 17 to move up and down along the direction of the lead screw, thereby adjusting the height position of the photoelectric ranging probe 16 and the receiver 15 relative to the workpiece being tested; thus achieving the effect of automatic height adjustment, improving detection flexibility and adapting to workpieces of different specifications.

[0034] Both sides of the lifting frame 5 are provided with sliding grooves that communicate with the interior. Both sides of the lifting block 17 are fixedly connected with sliders that cooperate with the sliding grooves. Specifically, through the cooperation between the sliding grooves on both sides of the lifting frame 5 and the sliders fixedly connected to both sides of the lifting block 17, the sliders slide synchronously in the sliding grooves during the up-and-down movement of the lifting block 17 driven by the lifting adjustment structure. This restricts the lateral displacement of the lifting block 17 and ensures that it can only move vertically in the set direction. This improves the linearity and guiding accuracy of the movement of the lifting block 17, prevents abnormal phenomena such as offset and jamming, and further ensures the accuracy of the measurement data.

[0035] This utility model provides a strength testing device for alloy material workpieces. Before testing, the alloy material workpiece to be tested is first placed between the clamping members 6 on the base 1, and the workpiece is firmly clamped by the upper and lower clamping members 6 to ensure that there is no displacement or slippage during the test. Then, the lifting cylinder 4 on the top plate 3 is activated. The output end of the cylinder is connected to the lifting plate 2. Under the push of the cylinder, the lifting plate 2 is moved downward along the support rod, so that the upper clamping member 6 applies a tensile force to the workpiece, simulating the stress state of the material in actual use. At the same time, a rotating ring 12 is provided at the center of the top of the base 1, and its bottom is rotatably connected to the top of the base 1 through a rotating base 7. This allows the rotating ring 12 to rotate stably under the action of the drive assembly. A lifting frame 5 is connected to the top of the rotating ring 12, and a lifting block 17 is slidably connected inside the lifting frame 5. A photoelectric ranging probe 16 and a receiver 15 are fixedly installed on one side of the lifting block 17 to collect deformation data of the workpiece during the stress process in real time. To accommodate workpieces of different heights, the lifting block 17 is connected to the top of the lifting frame 5 through a lifting adjustment structure. This lifting adjustment structure consists of a second drive motor 13 and a lead screw 14. The second drive motor 13 is installed on the top of the lifting frame 5, and its output shaft is connected to the lead screw 14. The lifting block 17 is threadedly engaged with the lead screw 14. When the second drive motor 13 starts, it drives the lead screw 14. The rotation causes the lifting block 17 to move up and down along the lead screw, adjusting the height position of the photoelectric ranging probe 16 and receiver 15 relative to the workpiece, thereby achieving accurate measurement in different height areas. To ensure that the lifting block 17 maintains good straightness during lifting, the lifting frame 5 has sliding grooves on both sides, and the lifting block 17 has sliders on both sides that cooperate with them. During the lifting adjustment, the sliders slide along the sliding grooves, effectively preventing the lateral deviation of the lifting block 17 and improving the guiding accuracy and running stability. The outer ring of the rotating ring 12 is provided with a driven gear disk 11, and a driving gear disk 9 is rotatably connected to one side of the top of the base 1. The driving gear disk 9 is connected to the driven gear disk 11 through a snap-fit ​​connection. The bottom of the base 1 is also equipped with a drive motor 8, which is linked with the active gear disk 9. During the test, after the drive motor 8 starts, it drives the active gear disk 9 to rotate, thereby driving the driven gear disk 11 and the entire rotating ring 12 to rotate through gear meshing. This, in turn, drives the lifting frame 5, lifting block 17, photoelectric ranging probe 16 and receiver 15 to perform circular motion around the workpiece being tested, realizing the acquisition of deformation data of the workpiece at different angles. In addition, the outer ring of the rotating base 7 is equipped with a mounting ring 10, which is fixedly connected to the top of the base 1 by bolts. This not only enhances the installation stability of the rotating ring 12 and its upper structure, but also facilitates quick disassembly and installation during later maintenance or replacement of parts.

[0036] The device's structural design fully considers the multi-angle detection requirements and ease of operation during the testing process, resulting in the following significant advantages: First, by setting up a combined structure of rotating ring 12, lifting frame 5, lifting block 17, and photoelectric ranging probe 16 and receiver 15, multi-directional and multi-angle synchronous detection of the tested alloy material workpiece is achieved. This solves the problem that traditional single-point detection methods cannot fully reflect the overall stress state of the material, significantly improving the completeness and accuracy of the test data. Second, the coordinated use of lifting cylinder 4 and lifting plate 2 makes the loading process more stable and controllable, improving the loading accuracy and repeatability during the test and ensuring the reliability of the test results. Third, the threaded transmission between drive motor 13 and lead screw 14 in the lifting adjustment structure, combined with the sliding groove and sliding... The guiding mechanism of the block enables automated adjustment of the height of the photoelectric ranging probe 16, which enhances the applicability of the equipment to workpieces of different specifications and improves detection efficiency and measurement flexibility. In addition, the rotating ring 12 is connected to the base 1 through the rotating base 7 and, together with the fixing structure of the mounting ring 10, further enhances the stability of the entire rotating system, avoids data deviation caused by shaking during rotation, and facilitates equipment maintenance and replacement. Finally, the drive assembly adopts a meshing transmission method of the active gear disk 9 and the driven gear disk 11, and is driven by the drive motor 8, realizing high-precision and continuous rotation control of the lifting frame 5 and its auxiliary structures. This ensures that the photoelectric ranging probe 16 can complete an all-round scan around the workpiece during the test, improving the automation level and test integrity of the detection.
