Description

Technical Field

[0001] This utility model relates to the field of load testing machine technology, and in particular to an automatic static mechanical load testing machine. Background Technology

[0002] In static mechanical load testing, existing testing equipment typically requires manual assistance for feeding, discharging, and tilting operations, resulting in a low level of automation. Furthermore, the tilting mechanism uses conventional rectangular beams as guide rails, which may be accidentally dislodged if excessive force is applied. Additionally, existing loading mechanisms usually involve cylinders driving iron plates to apply pressure, leading to inconsistent measurement accuracy and potential product damage. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an automatic static mechanical load testing machine.

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic static mechanical load testing machine, including a testing mechanism, an in-and-out flipping mechanism for feeding the product to be tested into the testing mechanism, and a control cabinet hanging on one side of the testing mechanism. The testing mechanism includes a first mounting frame, a hanging frame disposed on the upper part of the first mounting frame, a lifting drive mechanism for driving the hanging frame to move up and down along the first mounting frame, a number of sandbags hung on the hanging frame, and a number of laser sensors evenly distributed on the lower part of the hanging frame. The in-and-out flipping mechanism includes an in-and-out X-axis slide rail disposed at the bottom of the first mounting frame, a transfer platform that slides with the X-axis slide rail, an X-axis drive motor assembly that drives the transfer platform to slide along the X-axis slide rail, a Y-axis slide rail disposed on the transfer platform, a flipping frame that slides with the Y-axis slide rail, a Y-axis drive cylinder that drives the flipping frame to slide along the Y-axis slide rail, and a rotary drive cylinder mechanism that drives the flipping frame to rotate. The X-axis slide rail is an I-beam structure X-axis slide rail.

[0005] Furthermore, the bottom of the transfer stage is provided with multiple X-axis sliders, and each X-axis slider is provided with a T-slot that mates with the X-axis slider.

[0006] Furthermore, the laser sensor comprises 3-6 evenly distributed units.

[0007] Furthermore, the lifting drive mechanism includes multiple vertically arranged lifting screws and screw jacks that drive the lifting screws respectively. The lifting screws include at least four screws, which are respectively connected to the four corners of the hanging frame.

[0008] Furthermore, both ends of the tilting frame are connected to the transfer platform via rotating shafts. One end of the tilting frame is equipped with a rotary drive motor assembly that drives the rotating shaft to rotate. Positioning cylinders are respectively provided on both sides of the rotating shaft, and positioning blocks corresponding to the positioning cylinders are respectively provided at both ends of the tilting frame.

[0009] Furthermore, the X-axis drive motor assembly includes an X-axis drive motor, a belt assembly connected to the output end of the X-axis drive motor, and a rotary drive shaft connected to the output end of the belt assembly. The rotary drive shaft is connected to the X-axis slider for driving the X-axis slider to slide along the X-axis slide rail.

[0010] In use, the automatic static mechanical load testing machine of this utility model involves manually loading the product to be tested onto the infeed / turnover mechanism. This mechanism then delivers the product to the testing station of the testing mechanism. The machine is started via the control box to begin testing. After the testing mechanism performs the static mechanical load test, the infeed / turnover mechanism moves the product to the next testing station for further testing. Specifically, during testing, the lifting drive mechanism lowers the hanging frame and several sandbags to apply pressure to the product. Because the sandbags have a certain degree of flexibility, they do not cause damage to the product. Deformation measurement laser sensors distributed directly beneath the product detect the deformation data under pressure and feed it back to the control system in the control cabinet. After a single-piece test is completed, the lifting drive mechanism raises the hanging frame and sandbags back to their original position, and the infeed / turnover mechanism rotates 180 degrees. The product is flipped over so that the back is facing up. The hanging bracket is lowered and the pressure weight and time are set according to the program, and the deformation is detected. After the test is completed, the test mechanism is reset, and the in-and-out flipping mechanism removes the product, thus completing the single-piece product test. In addition, the X-axis slide rail is an I-beam structure X-axis slide rail, which is stable and reliable during the in-and-out flipping mechanism and will not deviate or derail.
