After the deformation indentation position of the aluminum profile after being squeezed by the pressure block is aligned with the U-shaped push plate, the U-shaped push plate can be pushed by the spring to pull the piston rod downward through the push-pull plate.
[0004] Traditional inspection equipment often generates debris during the workpiece inspection process, which can fly up under the pressure and cause injury to operators. Utility Model Content
[0005] The purpose of this invention is to provide a compressive strength testing device to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A compressive strength testing device includes a testing device platform, with support plates fixedly installed at both ends of the testing device platform, an assembly block fixedly installed on the top of the support plates, a drive motor fixedly installed on the top of the assembly block, a stamping column fixedly connected to the output end of the drive motor, a feeding plate movably installed inside the testing device platform, and a control panel fixedly installed on the front surface of the testing device platform.
[0008] Also includes:
[0009] A clamping mechanism is provided on the top of the loading plate and is used to fix and clamp the workpiece for testing, so as to perform stable testing.
[0010] A protective mechanism is provided on the outside of the clamping mechanism to protect the workpiece from flying debris and to safeguard the personal safety of the workers.
[0011] A further improvement of the present invention is that the clamping mechanism includes a detection cylinder, a platform is movably installed inside the detection cylinder, an arc-shaped groove is formed on the surface of the platform, a clamping plate is movably sleeved inside the arc-shaped groove, a transmission column is fixedly installed at the bottom of the platform, a drive gear is fixedly sleeved at the bottom of the transmission column, a transmission plate is meshed on the outside of the drive gear, and a hydraulic telescopic rod is fixedly installed on one side of the transmission plate.
[0012] A further improvement of this utility model is that an electric push rod is fixedly connected to one side of the feeding plate, and a servo motor is fixedly connected to the other end of the electric push rod.
[0013] A further improvement of this utility model is that an installation groove is provided on the outer side of the top of the detection cylinder, and a protective side cylinder is detachably connected inside the installation groove.
[0014] A further improvement of this utility model is that a connecting shaft is fixedly installed on the top of the protective side cylinder, and a connecting groove is provided on the outer side of the connecting shaft.
[0015] A further improvement of the present invention is that the protective mechanism includes a transparent cover, a fixing ring is fixedly installed inside the transparent cover, and a protective plate is fixedly installed on the inner side of the fixing ring.
[0016] A further improvement of this utility model is that a plug-in plate is fixedly installed at the bottom of the inner side of the transparent cover, and the bottom of the plug-in plate is movably sleeved inside the connecting groove.
[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0018] 1. This utility model provides a compressive strength testing device. A hydraulic telescopic rod receives commands from the control panel and applies a thrust to the transmission plate. Through the meshing relationship between the transmission plate and the drive gear, the transmission plate moves horizontally and drives the drive gear to rotate. This causes the stage, fixed to the top of the transmission column, to slowly rotate and fine-tune within the testing cylinder. The clamping plate within the arc-shaped groove on the surface of the stage, under the transmission linkage, slides along the arc-shaped groove towards the workpiece. Ultimately, the other end of the clamping plate moves inward to clamp the workpiece, forming a close-fitting clamp. This effectively avoids the problems of loosening or misalignment caused by differences in workpiece specifications in traditional fixing methods, significantly improving the adaptability of fixing different types of workpieces. Simultaneously, it ensures that the workpiece remains stable throughout the testing process, reducing interference with the testing results due to workpiece displacement.
[0019] 2. This utility model provides a compressive strength testing device. During the closing process of the protective mechanism, the insert plate at the bottom of the inner side of the transparent cover moves synchronously towards the connecting groove at the top of the protective side cylinder, forming a preliminary sleeve positioning. This sleeve structure provides clear guidance for the movement of the transparent cover, effectively limiting the offset trajectory of the transparent cover during the closing process. When the transparent cover is fully closed, the stable cooperation between the insert plate and the connecting groove also enhances the tightness of the connection between the transparent cover and the protective side cylinder, ensuring the formation of a complete closed protective space, completely blocking the splashing of workpiece debris during the testing process, providing reliable safety protection for operators, and reducing the risk of safety accidents.

Detailed Implementation
[0026] The present invention will be further described in detail below with reference to embodiments:
[0027] like Figure 1-5 As shown, this utility model has the following three specific embodiments.
[0028] Example 1
[0029] This utility model provides a compressive strength testing device, including a testing device platform 1, support plates 2 fixedly installed at both ends of the testing device platform 1, an assembly block 3 fixedly installed on the top of the support plate 2, a drive motor 5 fixedly installed on the top of the assembly block 3, a stamping column 4 fixedly connected to the output end of the drive motor 5, a feeding plate 6 movably installed inside the testing device platform 1, and a control panel 7 fixedly installed on the front surface of the testing device platform 1.
[0030] Also includes:
[0031] The clamping mechanism is located on the top of the loading plate 6 and is used to fix and clamp the workpiece to be tested for stable testing.
[0032] The protective mechanism is located on the outside of the clamping mechanism to protect the workpiece from flying debris and safeguard the personal safety of the workers.
[0033] like Figure 1 As shown, the operator places the workpiece to be inspected on the top of the loading plate 6. The clamping mechanism is activated, driving the clamping arm to move towards the workpiece. According to the shape characteristics of the workpiece, the adaptive clamping component of the clamping mechanism adjusts the clamping angle and force, firmly clamping the workpiece from both sides or all around. The loading plate 6 is controlled to move along a preset track inside the inspection equipment platform 1, conveying the workpiece to the position directly below the inspection area, that is, directly below the stamping column 4, achieving initial positioning of the workpiece. After the drive motor 5 is started, its output end drives the stamping column 4 to move downward vertically, applying pressure to the workpiece fixed on the clamping mechanism below. During the stamping process, the pressure sensor built into the equipment collects the pressure data applied by the stamping column 4 in real time, and the displacement sensor records the downward displacement of the stamping column 4 simultaneously. These data are fed back to the control panel 7 in real time through the data transmission module and dynamically displayed on the panel display screen in the form of curves or numbers. At the same time as the inspection, the protective mechanism is sleeved on the outside of the clamping mechanism, forming a semi-enclosed protective space to prevent workpiece debris from flying and causing personal injury to the operator during the inspection process.
[0034] Example 2
[0035] The difference from Embodiment 1 is that this embodiment discloses a detection cylinder 8 and a transparent cover 885. The clamping mechanism includes the detection cylinder 8, and a platform 81 is movably installed inside the detection cylinder 8. An arc-shaped groove 83 is formed on the surface of the platform 81, and a clamping plate 82 is movably sleeved inside the arc-shaped groove 83. A transmission column 84 is fixedly installed at the bottom of the platform 81, and a drive gear 85 is fixedly sleeved at the bottom of the transmission column 84. A transmission plate 86 is meshed on the outside of the drive gear 85. A hydraulic telescopic rod 87 is fixedly installed on one side of the transmission plate 86. An electric push rod 61 is fixedly connected to one side of the feeding plate 6, and a servo motor 62 is fixedly connected to the other end of the electric push rod 61. A connecting shaft 882 is fixedly installed on the top of the protective side cylinder 881, and a connecting groove 883 is formed on the outside of the connecting shaft 882. The protective mechanism includes a transparent cover 885, a fixing ring 886 is fixedly installed inside the transparent cover 885, and a protective plate 887 is fixedly installed on the inner side of the fixing ring 886.
[0036] like Figure 2 , 3 As shown in Figure 5, the operator places the workpiece to be tested on the surface of the stage 81 inside the testing cylinder 8. The hydraulic telescopic rod 87 receives the command from the control panel 7 and applies a thrust to the transmission plate 86. Because the transmission plate 86 is engaged with the drive gear 85, the thrust drives the transmission plate 86 to move horizontally, thereby driving the drive gear 85 to rotate. The drive gear 85 is fixedly sleeved at the bottom of the transmission column 84, and its rotation synchronously drives the transmission column 84 to rotate. The top of the transmission column 84 is fixedly connected to the stage 81, ultimately driving the stage 81 to slowly rotate and finely adjust inside the testing cylinder 8. The clamping plate 82 in the arc groove 83 is driven by the transmission linkage and slides along the arc groove 83 towards the workpiece, causing the other end of the clamping plate 82 to move inward to clamp the workpiece, achieving the function of adapting and fixing the workpiece. Then, before testing, the transparent cover 885 is installed above the testing cylinder 8. The fixing ring 886 and the protective plate 887 are set on the outside of the workpiece, so that the workpiece is blocked and protected from flying fragments during the compressive strength test, achieving the function of shielding and protecting.
[0037] Example 3
[0038] The difference from Embodiment 2 is that this embodiment discloses a detection cylinder 8 and a protective side cylinder 881. An installation groove 88 is provided on the outer side of the top of the detection cylinder 8. The protective side cylinder 881 is detachably connected inside the installation groove 88. A plug-in plate 884 is fixedly installed on the bottom of the inner side of the transparent cover 885. The bottom of the plug-in plate 884 is movably sleeved inside the connecting groove 883.
[0039] like Figure 4 , 5As shown, the plug plate 884 on the bottom inner side of the transparent cover 885 moves towards the connecting groove 883 on the top of the protective side cylinder 881 to form a preliminary sleeve positioning, preventing the transparent cover 885 from shifting during the closing process. The bottom of the protective side cylinder 881 is detachably connected to the inside of the mounting groove 88, which facilitates the easy disassembly of the detection cylinder 8 and thus makes it easy to clean the internal debris.
[0040] The working principle of this compressive strength testing equipment will be explained in detail below.
[0041] like Figure 1-5 As shown, the operator places the workpiece to be tested on the surface of the stage 81 inside the testing cylinder 8. The hydraulic telescopic rod 87 receives the command from the control panel 7 and applies a thrust to the transmission plate 86. Because the transmission plate 86 is engaged with the drive gear 85, the thrust drives the transmission plate 86 to move horizontally, thereby driving the drive gear 85 to rotate. The drive gear 85 is fixedly sleeved at the bottom of the transmission column 84, and its rotation synchronously drives the transmission column 84 to rotate. The top of the transmission column 84 is fixedly connected to the stage 81, ultimately driving the stage 81 to slowly rotate and finely adjust inside the testing cylinder 8. The clamping plate 82 in the arc groove 83 is driven by the transmission linkage and slides along the arc groove 83 towards the workpiece, causing the other end of the clamping plate 82 to move inward to clamp the workpiece, achieving the function of adapting and fixing the workpiece. Then, before testing, the transparent cover 885 is installed above the testing cylinder 8. The fixing ring 886 and the protective plate 887 are set on the outside of the workpiece, so that the workpiece is blocked and protected from flying fragments during the compressive strength test, achieving the function of shielding and protecting.
[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
