Description

Technical Field

[0001] This utility model relates to a coating testing device, specifically a coating layer hardness testing device. Background Technology

[0002] Coating is a process that involves applying one or more thin films to the surface of a substrate (such as metal, glass, plastic, ceramics, etc.) using physical or chemical methods. These films typically have specific functions, such as optical properties (anti-reflective, reflective), electrical properties (conductive, insulating), mechanical properties (wear-resistant, corrosion-resistant), or decorative effects.

[0003] Hardness is one of the key indicators of coating quality. High-hardness coatings usually have better wear resistance. Therefore, it is necessary to test the hardness of the coating. The hardness test of the coating is mainly carried out by placing the coating sample on the stage of a microhardness tester, adjusting the position of the stage so that the indenter is aligned with the test area on the surface of the coating, applying a load, and pressing the indenter into the surface of the coating to form an indentation. The shape of the indentation is then observed under a microscope, and the length of the diagonal of the indentation is measured. The measurement is repeated several times, and the average value is substituted into the microhardness calculation formula to obtain the microhardness of the coating. Before testing, the test object often needs to be fixed on a fixture. In traditional testing devices, improper placement of the testing device often obstructs the placement area, making it difficult for operators to accurately judge the placement position of the test object. This not only increases the difficulty of the placement operation, but may also affect the accuracy of subsequent test results due to placement deviations. Summary of the Invention

[0004] The purpose of this invention is to provide a coating hardness testing device to solve the problem mentioned in the background art that traditional testing devices often obstruct the placement area during the placement of the test object due to improper placement of the testing device, making it difficult for operators to accurately judge the placement position of the test object. This not only increases the difficulty of the placement operation, but may also affect the accuracy of subsequent test results due to placement deviations.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A coating layer hardness testing device includes a testing table and a fixed table. The top of the fixed table is provided with a fixing clamp for fixing the object to be tested. The top of the testing table is provided with a support frame for support and a slot provided on the support frame. A sliding guide mechanism and a deflection detection mechanism are provided on the sliding guide mechanism.

[0007] The deflection detection mechanism includes a threaded sliding mechanism that slides within the sliding guide mechanism. A deflection moving mechanism is provided on one side of the threaded sliding mechanism, and the sliding guide mechanism limits the movement of the deflection moving mechanism.

[0008] The coating hardness testing device described above: the sliding guide mechanism includes a cylinder disposed on the slot and a cavity formed on the cylinder. The cylinder is provided with a semi-circular groove and a vertical groove, and the cavity, the semi-circular groove and the vertical groove are interconnected.

[0009] The coating hardness testing device described above: the threaded sliding mechanism includes a sliding cylinder that slides on the cavity and an inner spiral groove formed on the inner wall of the sliding cylinder. A sliding block is connected to one side of the sliding cylinder, and the sliding block slides in conjunction with the semi-arc groove and the vertical groove.

[0010] The coating hardness testing device described above includes an adjusting screw rotatably mounted on a support frame and a connecting flange connected to the top of the adjusting screw. The inner spiral groove on the inner wall of the sliding cylinder engages with the external thread of the adjusting screw.

[0011] The coating hardness testing device described above: a drive motor and a drive shaft fixed on the output shaft of the drive motor are fixedly connected to the top of the support frame, and the drive shaft is connected to the adjusting screw through a connecting flange.

[0012] The coating hardness testing device described above includes a deflection and movement mechanism comprising a connecting arm fixed to one side of the sliding block, with an annular fixing member fixedly installed at one end of the connecting arm.

[0013] The coating hardness testing device described above includes a microhardness tester indenter mounted on the annular fixture, wherein the microhardness tester indenter cooperates with the fixture.

[0014] Compared with the prior art, the beneficial effects of this utility model are: through the coordinated cooperation of the sliding guide mechanism and the deflection detection mechanism, the detection device is located on one side of the object to be tested when the object is placed, which effectively avoids obstruction and ensures convenient and accurate placement operation. During the test, the device can automatically deflect to the top of the object to be tested and move vertically downward in the subsequent movement to realize the hardness detection function, ensuring that the contact angle between the detection head and the surface of the object to be tested is accurate.

[0015] This utility model also features a unique sliding guide mechanism that enables the testing mechanism to move along a fixed trajectory, achieving precise movement and avoiding hardness testing errors caused by angular deviations, thus improving the accuracy and reliability of the test results.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1-7 As an embodiment of the present utility model, the coating layer hardness testing device includes a testing platform 1 and a fixed platform 2. The top of the fixed platform 2 is provided with a fixing clamp 3 for fixing the test object. The top of the testing platform 1 is provided with a support frame 4 for support and a slot 5 provided on the support frame 4. The slot 5 is provided with a sliding guide mechanism and a deflection detection mechanism provided on the sliding guide mechanism.

[0026] The deflection detection mechanism includes a threaded sliding mechanism that slides within the sliding guide mechanism. A deflection moving mechanism is provided on one side of the threaded sliding mechanism, and the sliding guide mechanism limits the movement of the deflection moving mechanism.

[0027] In this embodiment, in the initial state, the object to be tested is first placed on the fixed clamp 3 on the top of the fixed platform 2. At this time, the testing device is located on one side of the object to be tested, which effectively avoids obstruction and ensures convenient and accurate placement. The deflection testing mechanism is activated, so that the thread sliding mechanism slides in the sliding guide mechanism. Due to the unique design of the sliding guide mechanism, the movement direction of the deflection moving mechanism can be guided, so that the device can automatically deflect to directly above the object to be tested and move vertically downward in subsequent movements to realize the hardness testing function, ensuring that the contact angle between the testing head and the surface of the object to be tested is accurate.

[0028] As a further embodiment of this utility model, the sliding guide mechanism includes a cylindrical body 6 disposed on the slot 5 and a cavity 7 formed on the cylindrical body 6. The cylindrical body 6 is provided with a semi-arc groove 9 and a vertical groove 8, and the cavity 7, the semi-arc groove 9 and the vertical groove 8 are interconnected.

[0029] In this embodiment, the cylinder 6 is disposed on the cavity 7. The cylinder 6 is hollow. Meanwhile, the semi-circular groove 9 and the vertical groove 8 provided on one side of the cylinder 6 are interconnected. The design of the semi-circular groove 9 and the vertical groove 8 can limit the moving position of the deflection moving mechanism.

[0030] As a further embodiment of this utility model, the threaded sliding mechanism includes a sliding cylinder 10 that slides on the cavity 7 and an inner spiral groove 11 formed on the inner wall of the sliding cylinder 10. A sliding block 12 is connected to one side of the sliding cylinder 10, and the sliding block 12 is in sliding cooperation with the semi-arc groove 9 and the vertical groove 8.

[0031] In this embodiment, the sliding cylinder 10 slides inside the cylinder 6, and the sliding block 12 connected to one side of the sliding cylinder 10 slides in the semi-arc groove 9 and the vertical groove 8.

[0032] As a further embodiment of this utility model, the threaded sliding mechanism further includes an adjusting screw 13 rotatably mounted on the support frame 4 and a connecting flange 14 connected to the top of the adjusting screw 13, wherein the inner spiral groove 11 on the inner wall of the sliding cylinder 10 is engaged with the external thread of the adjusting screw 13.

[0033] In this embodiment, the sliding cylinder 10 is threadedly connected to the external thread of the adjusting screw 13 through the inner spiral groove 11 designed on the inner wall. When the adjusting screw 13 rotates, the sliding cylinder 10 rotates accordingly.

[0034] As a further embodiment of this utility model, a drive motor 15 and a drive shaft 16 fixed on the output shaft of the drive motor 15 are fixedly connected to the top of the support frame 4. The drive shaft 16 is connected to the adjusting screw 13 through the connecting flange 14.

[0035] In this embodiment, the drive motor 15 is started, so that the output shaft of the drive motor 15 drives the adjusting screw 13 to rotate through the drive shaft 16 and the connecting flange 14. When the adjusting screw 13 rotates, it can drive the sliding cylinder 10 to move. At this time, the sliding block 12 on one side of the sliding cylinder 10 slides in the semi-arc groove 9. Then the sliding block 12 slides to the top of the vertical groove 8. As the sliding cylinder 10 continues to move downward, the sliding block 12 slides to the bottom of the vertical groove 8, thereby realizing the action of automatically deflecting the detection device to directly above the detection object and moving vertically downward in subsequent movements.

[0036] As a further embodiment of this utility model, the deflection and movement mechanism includes a connecting arm 17 fixed to one side of the sliding block 12, and an annular fixing member 18 is fixedly installed at one end of the connecting arm 17.

[0037] In this embodiment, when the sliding block 12 moves, it will simultaneously drive the connecting arm 17 and the annular fixing member 18 to move, so that the connecting arm 17 moves in the direction of the fixing clamp 3.

[0038] As a further embodiment of this utility model, the deflection and movement mechanism also includes a microhardness tester indenter 19 disposed on the annular fixing member 18, the microhardness tester indenter 19 cooperating with the fixing clamp 3.

[0039] In this embodiment, the sliding block 12 then drives the microhardness tester indenter 19 to move directly above the fixed fixture 3 via the connecting arm 17, thereby realizing the hardness detection function and ensuring that the contact angle between the test head and the surface of the test object is accurate.

[0040] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
