Description

Technical Field

[0001] This utility model relates to the technical field of passivation film surface quality preliminary inspection equipment, specifically a movable passivation film detection device. Background Technology

[0002] The formation of a passivation film on the surface of a steel plate is to improve the corrosion resistance of the steel plate, prevent surface contamination, and protect the steel plate from external environmental erosion. This film is usually formed through a surface passivation process, which involves covering the surface of the steel plate with a protective medium film, such as silicon dioxide, to prevent surface contamination and corrosion.

[0003] The initial inspection of the passivation film on the steel plate surface mainly uses the finger rubbing test. This method involves rubbing the passivation film on the steel plate surface twice back and forth with your index finger. If the passivation film is of good quality and uniformity, the rubbing mark will likely be shorter, and fewer pigment particles will adhere to your finger. Conversely, if the passivation film has quality problems, such as unevenness or defects, the rubbing mark will likely be longer, and more pigment particles will adhere to your finger. In short, the quality and uniformity of the passivation film on the steel plate surface are assessed by observing the length of the rubbing mark and the amount of pigment particles adhering to the finger.

[0004] This method requires inspectors to use their index fingers for testing, which causes some wear and tear on the inspectors' fingers. In addition, different inspectors apply different pressures, which can lead to errors in the grading and inspection of steel plates. Therefore, it is necessary to design a device to replace the fingers for testing in order to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a movable passivation film detection device with reasonable structural design, more convenient operation, easy processing, low processing cost, high detection efficiency, time and labor saving, protection for testing personnel, full protection of testing personnel's fingers, accurate detection, ensuring uniformity and consistency of detection force, and improving inspection quality.

[0006] This utility model discloses a movable passivation film detection device, comprising a vehicle body, a base plate fixedly mounted on the bottom surface of the vehicle body, casters fixedly mounted on the bottom surface of the base plate, a square tube fixedly mounted through the base plate, and a square hole provided on the contact surface between the square tube and the base plate; a box body fixedly mounted on the surface of the square tube, a box body base plate fixedly connected to the bottom surface of the box body, and the surface of the square tube fixedly connected to the box body base plate; a detection strip fixedly mounted on the inner wall of the square tube, the bottom end of the detection strip extending to the outside of the inner wall of the square hole, a first threaded hole provided on the inner wall of the square hole, and a wing screw installed through the first threaded hole to fix the detection strip to the inner wall of the square hole.

[0007] The vehicle body, casters, square tube, and inspection strip together constitute the main inspection component. It can move across the passivation film surface of the steel plate to be inspected, allowing for more time- and labor-saving inspections. The inspection strip, propelled by the casters, moves the vehicle body across the passivation film surface. Friction is generated between the inspection strip and the passivation film. Observation of the inspection strip after friction reveals that if the passivation film is of good quality and uniformity, the scratch length will be shorter, and fewer pigment particles will adhere to the inspection strip. Conversely, if the passivation film has quality problems, such as unevenness or defects, the scratch length may be longer, and more pigment particles will adhere to the inspection strip. Grading is performed by observing the length of the passivation film scratch and the amount of pigment particles adhered to the inspection strip to assess the quality and uniformity of the passivation film on the steel plate surface. The square tube, along with the first threaded hole and the wing screw, securely fixes the inspection strip to the inner wall of the square tube, ensuring a more reliable fixation, easy installation and disassembly, and smooth operation of the inspection work.

[0008] An upper positioning sleeve is fixedly installed on the bottom surface of the box base plate, and a lower positioning sleeve is fixedly installed on the surface of the base plate. Springs are installed inside the upper and lower positioning sleeves.

[0009] The number of upper and lower positioning sleeves is four.

[0010] The upper and lower positioning sleeves are fixed on the bottom and surface of the base plate of the chamber, respectively, and serve to fix the spring. The fixed installation is reliable. The upper and lower positioning sleeves and the spring can provide fixed support for the chamber. Not only is it firmly fixed, but there is also a certain elasticity margin for the movement of the chamber, which makes the chamber more durable and can extend the service life of the chamber, thereby extending the service life of the entire testing device.

[0011] Two first positioning strips are fixedly installed on each side of the inner wall of the vehicle body, and one second positioning strip is fixedly installed on each side of the outer wall of the box body. The second positioning strip is located between the two first positioning strips and is in contact with the side wall surface of the first positioning strip.

[0012] The surface of the box is provided with weights.

[0013] The surface of the weight is provided with a second threaded hole, through which a bolt is threadedly connected.

[0014] The weights are located on the surface of the chamber. According to the testing standards, a certain number of weights with a certain mass can be placed inside the chamber to apply force to the bottom surface of the test strip. This makes it easier for the test strip to detect the passivation film of steel plates of different grades, with a wider range of applications and more accurate testing. The bolts are fixed to the surface of the weights through the second threaded hole, and the weights can be lifted by the bolts.

[0015] The first positioning strip is fixedly installed on both sides of the inner wall of the vehicle body, and the second positioning strip is fixedly installed on both sides of the outer wall of the box body. The two first positioning strips provide sliding space for the second positioning strip, which is attached to the inner wall of the two first positioning strips. This allows the second positioning strip to slide freely on the inner wall of the two first positioning strips due to the application of different weights, enabling the box body to move up, down, left, and right. It also achieves limit positioning, fully ensuring the normal operation of the testing.

[0016] The caster wheel is fixedly installed on the base plate by a second bolt.

[0017] Handles are fixedly installed on both sides of the vehicle body.

[0018] The handles are fixedly installed on the side walls of both sides of the vehicle body and can be used to lift and move the entire detection device for easy operation.

[0019] The beneficial effects of this utility model are:

[0020] 1) The set-up vehicle body, casters, square tube, and inspection strip together constitute the main body of the inspection. It can move on the passivation film surface of the steel plate to be inspected according to the operator's operation, making the inspection more time-saving and labor-saving. The inspection strip, driven by the casters, moves the vehicle body on the passivation film surface of the steel plate. Friction is generated between the inspection strip and the passivation film. After friction, the inspection strip is observed. If the passivation film is of good quality and uniformity, the scratch length will be shorter, and the inspection strip will have fewer pigment particles adhering to it. Conversely, if the passivation film has quality problems, such as unevenness or defects, the scratch length may be longer, and the inspection strip will have more pigment particles adhering to it. Grading is performed by observing the length of the passivation film scratch and the amount of pigment particles adhering to the inspection strip to assess the quality and uniformity of the passivation film on the steel plate surface. The set-up square tube, and the cooperation between the first threaded hole and the wing screw, can fix the inspection strip to the inner wall of the square tube, making the fixation more secure, easy to install and disassemble, and ensuring the smooth operation of the inspection work.

[0021] 2) The upper and lower positioning sleeves are fixed on the bottom and surface of the bottom plate of the box, respectively, and serve to fix the spring. The fixed installation is reliable. The upper and lower positioning sleeves and the spring can provide fixed support for the box. Not only is it firmly fixed, but there is also a certain elasticity margin for the movement of the box, which makes the box more durable and can extend the service life of the box, thereby extending the service life of the entire testing device.

[0022] 3) The weights are located on the surface of the chamber. According to the testing standards, a certain number of weights with a certain mass can be placed inside the chamber to apply force to the bottom surface of the test strip. This makes it easier for the test strip to detect the passivation film of steel plates of different grades, with a wider range of applications and more accurate testing. The bolts are fixed to the surface of the weights through the second threaded hole, and the weights can be lifted by the bolts.

[0023] 4) The first positioning strip is fixedly installed on both sides of the inner wall of the vehicle body, and the second positioning strip is fixedly installed on both sides of the outer wall of the box body. The two first positioning strips can provide sliding space for the second positioning strip, which is attached to the inner wall of the two first positioning strips, so that the second positioning strip can slide arbitrarily on the inner wall surface of the two first positioning strips due to the application of different weights, realizing the up, down and left and right movement of the box body, and also realizing the limit, so as to fully ensure the normal operation of the test.

[0024] 5) The handles are fixedly installed on the side walls of both sides of the vehicle body and can be used to lift and move the entire detection device for easy operation.

[0025] 6) This testing device has a reasonable structural design, is more convenient to operate, is easy to process, has low processing and manufacturing costs, high testing efficiency, saves time and labor, can protect the testing personnel, fully protects the fingers of the testing personnel, has accurate testing, ensures the uniformity and consistency of testing force, improves the quality of inspection, has a wide range of applications, can be used for the detection of passivation film on steel plates of various grades, and has good testing effect, which is worthy of widespread promotion and application.
