Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices and relates to a material tensile testing machine. Background Technology

[0002] A tensile testing machine is a testing device based on the principle of tension. By measuring the load and deformation of components, it calculates the stress-strain curve, thereby determining the component's maximum load-bearing capacity, resistance to deformation, and other mechanical properties. It features simple structure, convenient operation, and accurate results, and is widely used in materials science, engineering, quality control, and research and development. In industrial production processes, factories frequently develop components with different structures and test the tensile properties of each produced component to ensure they meet standards. Tensile testing machines are commonly used for this purpose, making them widely applied in the industrial sector.

[0003] However, existing tensile testing machines still have some shortcomings. In the process of testing whether the tensile performance of parts is qualified, it is necessary to frequently change the parts to be tested. However, existing tensile testing machines usually use grippers to hold the parts, which makes the replacement process cumbersome and inefficient. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the current technology by proposing a material tensile testing machine. The technical problem to be solved by this invention is: how to improve the efficiency of the testing machine in testing the tensile properties of parts.

[0005] The objective of this utility model can be achieved through the following technical solution: A material tensile testing machine includes a base, on both sides of the top of the base are fixed mounting brackets, the inner side wall of the mounting bracket is provided with a vertically arranged sliding groove, the sliding groove is provided with a slidably connected pull rod, the bottom of the pull rod is provided with a fixed hook, the top of the base is provided with a fixed mounting platform, the mounting platform is provided with a fixed locking block, the top of the locking block is provided with a locking groove, the two sides of the locking block are provided with connecting brackets fixed to the mounting platform, the top of the connecting bracket is provided with a locking rod, and the locking rod is located directly above the locking block.

[0006] In this solution, the locking block and locking rod are used to fix the position of the component on the mounting platform. After the top of the component abuts against the locking rod, its bottom is inserted into the locking groove, which can easily complete the installation of the component. Then, the hook is fixedly connected to the installed component. The internal drive device pushes the pull rod upward. When the tension on the pull rod reaches the preset value, it is checked whether the component on the mounting platform is deformed by tension. In the above way, the installation of the component can be completed simply by locking the bottom of the component with the locking rod and then sliding the bottom into the groove, which improves the speed of component replacement and the efficiency of testing whether the tensile performance of the component meets the standard.

[0007] In the aforementioned material tensile testing machine, the bottom of the slot is provided with a limiting groove, the inner side of the limiting groove is provided with a pedal, the top of the pedal is provided with a pushing part, the pushing part abuts against the locking rod, and the bottom of the pedal is provided with a protruding mounting part. The structure with the limiting groove allows the bottom of the component to be further inserted into the limiting groove, making the installed component more stable. The pedal is the component being tested, and it is connected to the frame of the two-wheeled vehicle via the mounting part at the bottom. During use, the pushing part at the top allows rear passengers to easily open the pedal with their feet. During testing, the pushing part is used to engage with the connecting frame.

[0008] In the aforementioned material tensile testing machine, the hook is equipped with a fixed hanging rope, the bottom end of which is fixedly connected to the mounting part. The hook connects to the test component via the hanging rope. During the pedal test, the hanging rope connects to the mounting part on the pedal, ensuring uniform force distribution on the pedal.

[0009] In the aforementioned material tensile testing machine, slide rails are provided on both sides inside the slide groove. The two ends of the pull rod are slidably connected to the slide rails. A motor is located on the top of the mounting frame, and ropes are connected to the motor. The two ends of the ropes are fixedly connected to the two ends of the pull rod. The pull rod can move along the trajectory of the slide rails, and the motor, as the driving mechanism, pulls the pull rod upwards through the ropes at both ends.

[0010] In the aforementioned material tensile testing machine, hinged rollers are provided at both ends of the top of the chute, and the middle end of the rope rests on top of the rollers. The rollers are located at the top corners of the chute to change the direction of the rope's tension, enabling the rope to pull the lever vertically upwards.

[0011] In the aforementioned tensile testing machine for materials, the mounting platform is provided with several mounting holes, and the top of the clamping block and connecting frame is provided with several bolts. The bolts are threadedly connected to the mounting holes at the bottom, and the mounting platform is provided with a control console. The bolts are used to fix the clamping block and connecting frame to the mounting platform, and the structure of the clamping block and connecting frame can be changed according to the structure of the tested parts.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. In this solution, the installation of the component can be completed simply by engaging the bottom of the component with the connecting rod and then sliding the bottom into the groove. This improves the speed of component replacement and the efficiency of testing whether the tensile performance of the component meets the standards. Attached Figure Description
