Description

Technical Field

[0001] This utility model relates to the field of flatness detection technology, specifically to an object flatness detection device. Background Technology

[0002] Currently, flatness is a measure of the surface that is not perfectly flat during processing or production. The difference between the flatness and the absolute level is called flatness (the smaller the value, the better). Flatness of an object can be measured manually or by using relevant equipment.

[0003] The patented device for detecting the surface flatness of alloy steel, disclosed in patent number "CN214747893U", includes an outer protective box with an internal cavity. The outer protective box has legs at its lower end and openings on both sides, each containing a conveying device. This patented technology allows for the placement of a pressure sensor within the detection cavity above the top plate. A base plate is horizontally positioned above the detection cavity, and the pressure sensor is mounted on the base plate. A mounting plate is movably connected to the inner wall of the detection cavity via sliders and grooves at both ends. A roller is fitted against the surface of the alloy steel to be tested. A moving component drives the detection component to move laterally. During this movement, the roller rolls on the alloy steel surface. When unevenness is detected, the roller is pushed upwards, causing the top plate to move upwards and contact the pressure sensor, effectively detecting the flatness.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] If a deviation is detected on the surface of alloy steel, it is impossible to know how much the error differs between the defective and qualified items, and it is impossible to mark the location of the defect on the surface of the defective item. This makes it inconvenient for staff to find and measure the defect location of the alloy steel. Staff need to manually inspect the entire surface of the alloy steel to find possible defective areas, making it difficult to quickly rework the alloy steel, resulting in unnecessary delays in the production process and affecting the efficiency of inspection.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1, please refer to Figure 1-4 This utility model provides a technical solution:

[0025] A device for detecting the flatness of an object includes a support box 1 and a conveying component 2. A drive motor 3 is fixedly installed on one outer wall of the conveying component 2, and a drive rod 4 is fixedly connected to one end of the output shaft of the drive motor 3. The other end of the drive rod 4 is rotatably connected to one inner wall of the support box 1. A drive block 5 is threadedly connected to the outer wall of the drive rod 4, and a measuring and positioning mechanism 6 is provided at the bottom of the drive block 5.

[0026] Furthermore, the measuring and positioning mechanism 6 includes a support cylinder 601, and a cavity 602 is provided at the bottom of the support cylinder 601. A slide rod 604 is slidably connected to the inner wall of the cavity 602, and a detection block 606 is fixedly connected to the bottom of the slide rod 604. A through groove 607 is provided through one side of the outer wall of the support cylinder 601. A magnetic pen 608 is fixedly connected to the outer wall of the slide rod 604 facing the through groove 607, and a magnetic drawing board 609 is attached to the other end of the magnetic pen 608.

[0027] More specifically, in this embodiment, when performing flatness testing on alloy steel, the alloy steel material is first moved to the testing position by the conveying component 2, and then the drive rod 4 is rotated by the drive motor 3 to drive the drive block 5 to move by the thread, thereby causing the testing block 606 to slide across the surface of the alloy steel. When an uneven position is encountered, the testing block 606 can be lifted up, so that the slide rod 604 uses the elastic force of the spring 605 to drive the upper limit block 611 to squeeze the pressure sensor 603, thereby triggering an alarm. For a more detailed testing process, please refer to the above-mentioned comparative document, which will not be repeated here.

[0028] Next, a through groove 607 is formed through one side of the outer wall of the support cylinder 601, and a magnetic pen 608 is fixedly connected to the outer wall of the slide rod 604 facing the through groove 607. The other end of the magnetic pen 608 is attached to a magnetic drawing board 609. When the drive block 5 moves the detection block 606, the magnetic pen 608 can move synchronously on the surface of the magnetic drawing board 609 and draw a horizontal line. When the detection block 606 moves the slide rod 604 upward, the magnetic pen 608 can draw a vertical line on the surface of the magnetic drawing board 609. The position of the vertical line on the magnetic drawing board 609 can be used to guide the workers to find the position of the alloy steel. At the same time, the length of the vertical line can be measured to determine the approximate error of the defective item, which is conducive to the rapid rework of the alloy steel and ensures the detection efficiency of the device.

[0029] Example 2:

[0030] Based on the above embodiments, a sliding groove 7 is provided through one side of the outer wall of the support box 1, and a connecting rod 8 is slidably connected to the inner wall of the sliding groove 7. A magnetic eraser 9 is fixedly connected to one end of the connecting rod 8 facing the magnetic drawing board 609, and one side of the outer wall of the magnetic eraser 9 is slidably attached to one side of the outer wall of the magnetic drawing board 609. A sliding column 10 is slidably connected inside the connecting rod 8, and both ends of the sliding column 10 are fixedly connected to the inner wall of the sliding groove 7.

[0031] More specifically, in this embodiment, after the defective item is removed, a connecting rod 8 is slidably connected to the inner wall of the slide groove 7, and a magnetic wiping plate 9 is fixedly connected to one end of the connecting rod 8 facing the magnetic drawing board 609. The outer wall of one side of the magnetic wiping plate 9 is slidably attached to the outer wall of one side of the magnetic drawing board 609, thereby pulling the connecting rod 8 to move the magnetic wiping plate 9 from one side of the back of the magnetic drawing board 609 to the other side of the back, thereby attracting the magnet inside the magnetic drawing board 609 back to its original position, achieving the effect of quickly restoring the magnetic drawing board 609, and facilitating the re-inspection work.

[0032] Next, a sliding column 10 is slidably connected inside the connecting rod 8, and the two ends of the sliding column 10 are fixedly connected to the inner wall of the sliding groove 7. This allows the sliding column 10 to restrict the movement direction of the connecting rod 8, ensuring the stability of the connecting rod 8 during movement.

[0033] Next, an installation block 11 is fixedly connected to one side of the outer wall of the support cylinder 601, and a fan 12 is fixedly installed on the bottom inclined surface of the installation block 11. In this way, during the detection process, the fan 12 blows air on the moving path of the alloy steel surface in advance to remove surface impurities and avoid them from causing unnecessary errors, thereby ensuring the detection efficiency of this device.

[0034] Working principle: First, when the drive block 5 moves the detection block 606 to perform detection, it can simultaneously move the magnetic pen 608 on the surface of the magnetic drawing board 609 and draw a horizontal line. When the detection block 606 moves the slide bar 604 upward, it can simultaneously move the magnetic pen 608 on the surface of the magnetic drawing board 609 to draw a vertical line. Thus, the position of the vertical line on the magnetic drawing board 609 can be used to guide the staff to find the position of the alloy steel. At the same time, the length of the vertical line can be measured to determine the approximate error of the defective item.

[0035] Next, the blower 12 is used to blow air along the moving path of the alloy steel surface to remove surface impurities and avoid unnecessary errors. At the same time, after the defective item is removed, the connecting rod 8 can be pulled to move the magnetic wiping plate 9 from one side of the back of the magnetic drawing board 609 to the other side of the back, so that the magnet inside the magnetic drawing board 609 can be pulled back to its original position, achieving the effect of quickly restoring the magnetic drawing board 609 and facilitating the re-inspection work.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
