[0002] Mechanical parts refer to individual, indivisible components in machinery. They are the basic building blocks of machines and the basic units in the mechanical manufacturing process. In the rapid development of modern society, new mechanical equipment is constantly being manufactured. Various heavy industries require materials with certain properties, such as round parts. During the production and processing of mechanical parts, it is often necessary to test the pressure strength of the parts. Currently, strength testing devices are commonly used to test the pressure strength of the parts.

[0003] When conducting strength tests, some methods involve applying pressure to the part to test its strength. However, this test often only measures the stress on a cross section, and it is difficult to analyze the state when testing in the opposite direction to the axis, thus affecting the test results.

As the punching head presses down on the workpiece, the position of the cross-section relative ring changes, and the cross-section relative ring is clamped and fixed by the two fixing clamps.

[0006] The vertical fixing seat is provided with a sliding groove, and the fixing plate is slidably connected in the sliding groove.

[0007] The fixed clamp is fixedly connected to two ends with blocks, and the length of the fixed clamp is three times the width of the vertical fixing seat.

[0011] One of the fixing plates has a first screw inserted into it, and the first screw is threadedly connected to the other fixing plate.

[0012] The beneficial effects of this utility model are:

[0013] The cross-sectional relative detection component includes a cross-sectional relative ring, an upright fixing seat, and a base. During detection, the workpiece is placed upright on the worktable, and the cross-sectional relative ring is placed on the side cross-section of the workpiece.

[0020] Please see Figures 1-4The present invention provides the following technical solution: it includes a workbench 1, a punching head 11 for strength testing is provided above the workbench 1, and a cross-section relative detection component 2 is provided on the top of the workbench 1. The cross-section relative detection component 2 includes a cross-section relative ring 21, a vertical fixing seat 22 and a base 23. The cross-section relative ring 21 is opposite to the cross-section of the circular workpiece. The vertical fixing seat 22 is located outside the cross-section relative ring 21. The vertical fixing seat 22 is fixedly connected to the base 23. Two fixing clamps 24 are slidably connected inside the vertical fixing seat 22. As the punching head 11 presses down on the workpiece, the position of the cross-section relative ring 21 changes, and the cross-section relative ring 21 is fixed by the two fixing clamps 24.

[0021] In this implementation scheme: A punching head 11 for strength testing is provided above the workbench 1. The punching head 11 is activated to press down on the workpiece placed on the workbench 1 to test the strength of the part. The cross-section relative detection assembly 2 includes a cross-section relative ring 21, a vertical retaining seat 22, and a base 23. The cross-section relative ring 21 is opposite to the cross-section of the circular workpiece. The vertical retaining seat 22 is located outside the cross-section relative ring 21 and is fixedly connected to the base 23. Two fixed clamping plates 24 are slidably connected inside the vertical retaining seat 22. During testing, the workpiece is placed vertically on the workbench 1, and the cross-section relative ring 21 is placed at the side cross-section of the workpiece. The punching head 11 is used to press down on the workpiece to test its strength. If the cross-section relative ring 21 shows signs of compression... The cross-sectional ring 21 can be held by two fixed clamping plates 24. The relative position of the cross-sectional ring 21 and the scale line 27 can be analyzed to record the detection status, facilitate the analysis work, and improve the detection effect. When the position of the fixed clamping plates 24 is changed, the distance between the two fixed clamping plates 24 is changed by the first screw 25. When the two fixed clamping plates 24 are holding the top middle position of the cross-sectional ring 21, they can be locked by the first screw 25. The position of the fixed clamping plates 24 can be changed by the second screw 26, so that the fixed clamping plates 24 can move along the sliding groove 221. The fixed clamping plates 24 can be aligned with the position where the top of the cross-sectional ring 21 is deformed. By pulling out the pin 28, the cross-sectional ring 21 can be removed for analysis.

[0022] The vertical fixing seat 22 has a sliding groove 221, and the fixing plate 24 is slidably connected in the sliding groove 221. The position of the fixing plate 24 can be changed by the second screw 26, so that the fixing plate 24 moves along the sliding groove 221 and can be positioned at the position where the top of the ring 21 is deformed relative to the cross section.

[0023] Both ends of the fixed clamp 24 are fixedly connected to the stop block 241. The length of the fixed clamp 24 is three times the width of the vertical fixed seat 22. The fixed clamp 24 can move in the direction of the cross section relative ring 21 facing the cross section relative ring 21, and in the direction away from the cross section relative ring 21.

[0024] The outer side of the vertical retaining base 22 has a scale line 27 at the top position, which is opposite to the cross-sectional relative ring 21. The cross-sectional relative ring 21 is elastic. According to the relative position analysis of the cross-sectional relative ring 21 and the scale line 27, the detection state can be recorded. By releasing the fixing clamp 24, the cross-sectional relative ring 21 can be restored to its original deformation and can be reused.

[0025] A pin 28 is inserted into the base 23, and one end of the pin 28 is inserted into the worktable 1. The pin 28 serves as a positioning tool. By pulling out the pin 28, the cross-section relative ring 21 can be removed for analysis.

[0026] The top of the vertical mounting base 22 is threaded with a second screw 26. One end of the second screw 26 is rotatably connected to one of the fixing plates 24. A first screw 25 is inserted into one of the fixing plates 24 and threadedly connected to the other fixing plate 24. Fastening nuts are provided on the outside of the first screw 25 and the second screw 26, which restrict the position of the fixing plates 24.

[0027] The working principle and usage process of this utility model are as follows: The stamping head 11 is activated to press down on the workpiece placed on the worktable 1 to test the strength of the part. The cross-section relative ring 21 is aligned with the cross-section of the circular workpiece. The vertical retaining seat 22 is located outside the cross-section relative ring 21 and is fixedly connected to the base 23. Two fixed clamping plates 24 are slidably connected inside the vertical retaining seat 22. During testing, the workpiece is placed vertically on the worktable 1, and the cross-section relative ring 21 is placed at the side cross-section of the workpiece. The stamping head 11 is used to press down on the workpiece to test its strength. If the cross-section relative ring 21 shows signs of compression, it can be clamped by the two fixed clamping plates 24. Based on the analysis of the relative position of the cross-sectional ring 21 and the scale line 27, the detection status can be recorded, which is beneficial to the progress of analysis and improves the detection effect. When the position of the fixed clamp 24 is changed, the distance between the two fixed clamps 24 is changed by the first screw 25. When the two fixed clamps 24 clamp the top middle position of the cross-sectional ring 21, they can be locked by the first screw 25. The position of the fixed clamp 24 can be changed by the second screw 26, so that the fixed clamp 24 moves along the sliding groove 221. The fixed clamp 24 can be aligned with the position where the top of the cross-sectional ring 21 is deformed. By pulling out the pin 28, the cross-sectional ring 21 can be removed for analysis.
