Description

Technical Field

[0001] This utility model relates to the field of paint hardness testing technology, specifically a device for testing the hardness of paint after lacquer production. Background Technology

[0002] After curing, lacquer has both high hardness and a certain degree of toughness. Before using lacquer, it is necessary to test its hardness using a paint hardness testing device. A specific shaped indenter is pressed into the surface of the lacquer film for a certain period of time under a fixed load. After unloading, the diagonal length of the indentation is measured, and the hardness value is calculated. A high hardness value indicates strong resistance to indentation.

[0003] A search of Chinese patent CN209542406U reveals a grid scraping table for testing paint adhesion, comprising a grid table with a square placement frame on the table surface and a fixing component on the placement frame that abuts against and fixes one side wall of the paint plate. This patent can increase the stability of scraping the paint plate and reduce the disadvantage of the paint plate easily scratching fingers.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. Traditional hardness testing devices take a long time to locate the paint when testing it, and it is difficult to load and unload multiple painted workpieces when testing them. Errors are easily generated when manually locating the indentation position and measuring the diagonal. Furthermore, there is a lack of a synchronous comparison and recording mechanism for multiple indentations. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for testing the hardness of paint after lacquer production.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a paint hardness testing device after paint production, including a machine body, a pressing mechanism and a placement mechanism on the machine body, and a measuring mechanism on the pressing mechanism.

[0008] The placement mechanism includes a guide assembly disposed on the body, a plurality of support assemblies disposed on the guide assembly, a placement platform disposed on each of the support assemblies, a support plate fixedly mounted on the placement platform, and a plurality of positioning assemblies disposed on the guide assembly.

[0009] The measuring mechanism includes two electric cylinders mounted on the pressing mechanism. A guide plate is fixedly mounted on the telescopic ends of the two electric cylinders. Multiple moving components are mounted on the guide plate. Each moving component is equipped with a scale sleeve, and a pointer is slidably mounted on the inner side of the scale sleeve.

[0010] Furthermore, the pressing mechanism includes a fixed frame fixedly installed on the machine body, a hydraulic cylinder is provided on the fixed frame, and a pressure block is fixedly installed on the telescopic end of the hydraulic cylinder.

[0011] Furthermore, the guide assembly includes two guide shells fixedly mounted on the body.

[0012] Furthermore, a slide bar is slidably installed on the inner side of each guide shell, and a flat plate is fixedly installed on both slide bars.

[0013] Furthermore, the support assembly includes two side sleeves fixedly installed on the flat plate. Each side sleeve has a spring connected to its inner wall. The end of the spring is connected to a telescopic rod that is slidably connected to the side sleeve, and the two telescopic rods are fixed together to the placement platform.

[0014] Furthermore, the positioning component includes a threaded bracket fixedly mounted on the flat plate, and a positioning bolt adapted to the support plate is threaded onto the threaded bracket.

[0015] Furthermore, the movable component includes a movable sleeve slidably mounted on the guide plate, the movable sleeve being threaded with a compression bolt.

[0016] The above-described solution of this utility model has at least the following beneficial effects:

[0017] 1. In this utility model, multiple paint plates are placed inside the placement platform. By moving the plate, the plate moves the slide bar into the inside of the guide shell, and the paint plates are moved sequentially to the positions corresponding to the pressure block. The support plate is pushed, and the support plate moves the paint plates to the bottom of the pressure block through the placement platform. The positioning bolt is screwed into the inside of the support plate to fix the placement platform. The hardness of the paint plates is tested. After the test, the positioning bolt is screwed out from the inside of the support plate, so that the spring can use its own elasticity to drive the placement platform to reset and move through the telescopic rod.

[0027] like Figures 1 to 5 As shown, an embodiment of this utility model provides a paint hardness testing device after paint production, including a body 1, a pressing mechanism and a placement mechanism on the body 1, and a measuring mechanism on the pressing mechanism. The pressing mechanism includes a fixed frame 2 fixedly installed on the body 1, a hydraulic cylinder 3 fixedly installed on the fixed frame 2, and a pressure block 4 fixedly installed on the telescopic end of the hydraulic cylinder 3.

[0028] In this embodiment of the utility model, the worker places the paint plate at the bottom of the pressure block 4, controls the extension end of the hydraulic cylinder 3 to extend, so that the extension end of the hydraulic cylinder 3 can drive the pressure block 4 to move downward, so that the pressure block 4 presses down on the paint plate to test the hardness of the paint.

[0029] Figures 1 to 5As shown, the placement mechanism includes a guide assembly mounted on the body 1. The guide assembly is provided with multiple sets of support assemblies, and each set of support assemblies is provided with a placement platform 11. A support plate 12 is fixedly installed on the placement platform 11. The guide assembly is provided with multiple sets of positioning assemblies. The guide assembly includes two guide shells 5 fixedly mounted on the body 1. A slide bar 6 is slidably mounted on the inner side of each guide shell 5. A plate 7 is fixedly mounted on both slide bars 6. The support assembly includes two side sleeves 8 fixedly mounted on the plate 7. A spring 9 is connected to the inner wall of each side sleeve 8. The end of the spring 9 is connected to a telescopic rod 10 that is slidably connected to the side sleeve 8. The two telescopic rods 10 are fixedly fixed to the placement platform 11. The positioning assembly includes a threaded bracket 13 fixedly mounted on the plate 7. A positioning bolt 14 adapted to the support plate 12 is threadedly mounted on the threaded bracket 13.

[0030] In this embodiment of the utility model, the operator places multiple paint plates inside the placement platform 11, moves the plate 7 to move the slide bar 6 into the inside of the guide shell 5, and moves the paint plates sequentially to the corresponding positions of the pressure block 4. The operator then pushes the support plate 12, which moves the paint plates to the bottom of the pressure block 4 via the placement platform 11. The operator screws the positioning bolt 14 into the inside of the support plate 12 to fix the placement platform 11, and performs a hardness test on the paint plates. After the test, the operator screws the positioning bolt 14 out of the inside of the support plate 12, allowing the spring 9 to use its own elasticity to move the placement platform 11 back to its original position via the telescopic rod 10. Then, by moving other paint plates to the bottom of the pressure block 4, it is convenient to test multiple paint plates.

[0031] Figures 1 to 5 As shown, the measuring mechanism includes two electric cylinders 15 fixedly mounted on the pressing mechanism. A guide plate 16 is fixedly mounted on the telescopic ends of the two electric cylinders 15. Multiple moving components are provided on the guide plate 16.

The moving component includes a moving sleeve 17 slidably mounted on the guide plate 16. A compression bolt 18 is threaded onto the moving sleeve 17.

[0032] In this embodiment of the utility model, after testing multiple painted panels, the operator controls the extension end of the electric cylinder 15 to extend, causing the extension end of the electric cylinder 15 to drive the pointer 20 downward through the guide plate 16, the moving sleeve 17, and the scale sleeve 19, so that the pointer 20 contacts the painted panel. By pushing the moving sleeve 17, the moving sleeve 17 drives the pointer 20 to the pressing position of the painted panel through the scale sleeve 19, so as to measure the concave hole caused by the pressing on the painted panel. By twisting the compression bolt 18 to abut against the guide plate 16, the moving sleeve 17 is fixed. The scale on the scale sleeve 19 makes it convenient to test, compare, and record multiple painted panels at the same time.

[0033] Working principle: The operator places multiple paint panels inside the placement platform 11. By moving the plate 7, the plate 7 moves the slide bar 6 inside the guide housing 5, sequentially moving the paint panels to their corresponding positions on the pressure block 4. The support plate 12 is then pushed, causing it to move the paint panels to the bottom of the pressure block 4 via the placement platform 11. The positioning bolt 14 is screwed into the inside of the support plate 12 to fix the placement platform 11. The extension end of the hydraulic cylinder 3 is extended, allowing it to move the pressure block 4 downwards, pressing the paint panels down for paint hardness testing. After the test, the positioning bolt 14 is unscrewed from the inside of the support plate 12, allowing the spring 9 to use its own elasticity to move the placement plate through the extension rod 10. The platform 11 is reset and moved. Then, by moving other painted panels to the bottom of the pressure block 4, multiple painted panels are tested. After testing multiple painted panels, the extension end of the electric cylinder 15 is extended, and the extension end of the electric cylinder 15 drives the pointer 20 downward through the guide plate 16, the moving sleeve 17 and the scale sleeve 19, so that the pointer 20 contacts the painted panel. By pushing the moving sleeve 17, the moving sleeve 17 drives the pointer 20 to the pressing position of the painted panel through the scale sleeve 19 to measure the concave hole caused by the pressing on the painted panel. The guide plate 16 is abutted by tightening the clamping bolt 18 to fix the moving sleeve 17. The multiple painted panels are tested, compared and recorded through the scale on the scale sleeve 19.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
