Description
Technical Field
[0001] This application relates to the field of flatness testing equipment technology, specifically a tool for testing the flatness of thin-walled square tubes. Background Technology
[0002] Thin-walled square tubes refer to square steel tubes with relatively thin walls, typically ranging from 0.5mm to 2mm, with an alloy content of approximately 0.07% to 0.13%. They possess high compressive strength, good corrosion resistance, and excellent mechanical properties, making them widely used in building structures and machinery manufacturing. In construction, thin-walled square tubes are often used to build lightweight steel structure frames. Their lightweight nature facilitates construction and installation, effectively reducing the building's self-weight and lowering foundation load requirements. Simultaneously, they provide stable and reliable structural support, ensuring the building's safety and stability. In the machinery manufacturing industry, thin-walled square tubes play a crucial role as an important component. They can be used to manufacture various mechanical frames, supports, and other structural parts, ensuring the stability and reliability of mechanical equipment during operation thanks to their good strength and rigidity. Thin-walled square tubes also have excellent processing performance. They are easy to cut, weld and bend, and can be processed into various complex shapes and sizes according to different application needs to meet diverse design requirements. During the planar milling process of thin-walled square tubes, deformation is easily generated due to their thin wall thickness. Therefore, it is necessary to check the flatness of the machined surface after machining to determine whether it meets the machining requirements. Thus, it is necessary to provide a flatness inspection tool for thin-walled square tubes to solve the above problem.

[0013] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0014] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.
[0015] like Figures 1-2 As shown, this application provides a flatness testing tool for thin-walled square tubes, including a base 1, a boss 2 fixedly installed at the middle position of the base 1, and a support 5 fixedly installed at the upper end of the boss 2, the support 5 having a V-shaped support portion; Meanwhile, a core rod is inserted inside the thin-walled square tube (hereinafter referred to as square tube 4), and the two ends of the core rod overlap on the V-shaped support, thereby realizing the placement of square tube 4 during testing; It should be noted that, since the tooling for milling the plane of square tube 4 is generally an internal support tooling, positioning by mandrel is more accurate. Furthermore, a clamp 3 is press-fitted onto the top of the square tube 4, which is used to fix the square tube 4. In order to perform flatness detection on the square tube 4, a three-axis moving mechanism is provided on the base 1. The three-axis moving mechanism includes a first moving mechanism 7 provided on the base 1. The first moving mechanism 7 is an existing lead screw and slide rail mechanism, and the first moving mechanism 7 has a first slider suitable for sliding along the length direction of the square tube 4. Meanwhile, a second moving mechanism 9 is provided on the first slider. The second moving mechanism 9 is also a lead screw and slide rail mechanism, and the second moving mechanism 9 has a second slider that slides along the direction perpendicular to the length of the square tube 4. Furthermore, a third moving mechanism 10 is provided on the second slider. This third moving mechanism 10 is also a lead screw and slide rail mechanism, and it has a third slider that slides vertically. A gauge is mounted on this third slider, so that the position of the gauge can be adjusted by the second moving mechanism 9 and the third moving mechanism 10, and the gauge can be moved by the first moving mechanism 7 to inspect the flatness of the square tube 4. Specifically: like Figures 1-3 As shown, the inspection tool includes a base 11 fixedly mounted on a third slider. A vertical rod 12 is provided at the upper end of the base 11, and a horizontal rod 13 is provided at the upper end of the vertical rod 12. A first lock 14 is provided between the horizontal rod 13 and the vertical rod 12. The first lock 14 is used to fix the horizontal rod 13 to the vertical rod 12, and the position of the horizontal rod 13 in the up-down and left-right directions can be adjusted as needed. Meanwhile, a dial 8 is installed at one end of the crossbar 13, and a dial 15 is provided on the dial 8. The dial 15 is used to contact the surface of the square tube 4. Therefore, when it is necessary to test the flatness of the square tube 4, the position of the pointer 15 is adjusted by the second moving mechanism 9 and the third moving mechanism 10 so that the pointer 15 contacts the plane of the square tube 4. Then, the first moving mechanism 7 drives the pointer 15 to move along the length of the square tube 4, thereby measuring the flatness of the entire plane of the square tube 4. It should be noted that the dial 8 and the hands 15 can be made using dial indicators from existing technology, which allows for a more accurate measurement of the flatness of the square tube 4.
[0016] When the flatness of the square tube 4 varies significantly, the limited elasticity of the hand 15 may cause damage to it due to excessive fluctuations. To address this issue, such as... Figures 3-6 As shown, two sets of lugs 22 are provided on the base 11. Each lug 22 has a through rotating hole (not shown in the figure). A connecting seat 18 is provided between the two sets of lugs 22. The connecting seat 18 has a mating hole 21. A second lock 17 is fixedly installed in the mating hole 21. The second lock 17 is rotatably mounted on the rotating hole, so that the connecting seat 18 can rotate around the center of the rotating hole. In order to control the rotation angle of the connecting seat 18, a threaded hole 20 is provided at one end of the connecting seat 18. A bolt 19 is installed in the threaded hole 20. At the same time, a groove 16 is provided on the base 11. The bolt 19 passes through the threaded hole 20 and contacts the bottom of the groove 16. By screwing the bolt 19 in and out of the threaded hole 20, the distance between the bolt 19 and the bottom of the groove 16 can be adjusted, thereby adjusting the angle of the connecting seat 18. It should be noted that the upright 12 is fixedly installed with the second lock 17, so the tilt angle of the upright 12 can be adjusted by adjusting the angle of the connecting seat 18 to adapt to different measurement needs; Continue to refer to Figures 4-6 A square groove 23 is provided at the other end of the connecting seat 18. The square groove 23 is arc-shaped, and the center of the square groove 23 coincides with the rotation center of the connecting seat 18. At the same time, multiple sets of springs 25 are fixedly installed on the side of the square groove 23. A slider 26 is fixedly installed at the end of the spring 25, and the slider 26 is located inside the square groove 23. Meanwhile, an extension platform 27 is provided on the slide plate 26, and a ratchet 28 is provided on the extension platform 27. A side window 24 is provided on the side of the square groove 23, and the ratchet 28 passes through the side window 24 and protrudes from the side of the connecting seat 18. Furthermore, multiple sets of locking grooves 29 adapted to the ratchet 28 are provided on the side of the groove 16, so that when the angle of the connecting seat 18 is adjusted, the connecting seat 18 can be initially fixed by the ratchet 28 cooperating with one set of locking grooves 29. When the flatness of the square tube 4 differs significantly, the hands 15 will be subjected to a large reaction force. This reaction force will act on the connecting seat 18, causing the ratchet 28 to tend to move downward relative to the matching locking groove 29. At this time, due to the action of the spring 25, the slider 26 will move towards the spring 25, thereby causing the ratchet 28 to disengage from the matching locking groove 29 and move to the next set of locking grooves 29 to engage and lock, thus buffering the hands 15 and preventing damage to the hands 15.
[0017] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
