Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, and specifically, to a high-temperature resistant testing device for ceramic coatings. Background Technique

[0002] High-temperature resistant coating materials are coatings applied to objects that need to withstand high-temperature environments. They can be used as coating materials for ceramics, glass, metals, etc. The coating is sprayed on the surfaces of metals, quartz, etc., and dried at low temperature. It has very good adhesion, is hard, does not crack, and does not blister. It can be used on the surfaces of iron, steel, quartz, ceramics, glass, etc., especially in quartz heating tubes. However, there is a lack of detection methods for high-temperature resistant material coatings at present, and there is no relatively simple instrument for detecting high-temperature resistant coatings.

[0003] After retrieval, the "high-temperature resistant tester for coatings" disclosed in the Chinese patent publication No. CN212228779U includes a high-temperature detection tank, a pop-up test piece detection component, a rotary control type limiting detection mechanism, and a detection tank sealing cover. The high-temperature detection tank is hollow, the detection tank sealing cover is arranged on the top of the high-temperature detection tank, the pop-up test piece detection component is arranged on the bottom wall of the high-temperature detection tank, the rotary control type limiting detection mechanism passes through the detection tank sealing cover and is arranged in the high-temperature detection tank. The pop-up test piece detection component includes a pop-up spring and a test piece placement rack. The pop-up spring is arranged on the bottom wall of the high-temperature detection tank, the test piece placement rack is arranged on the pop-up spring, a coating test piece is arranged on the test piece placement rack, and a pop-up channel is arranged at the corresponding position of the detection tank sealing cover and the test piece placement rack.

[0004] The above patent can limit or release the test piece placement rack by rotating the rotation control rod, and its main purpose is to facilitate the taking and placing of coating test pieces. During the detection process, the temperature inside the high-temperature detection tank is increased mainly by starting the heater to achieve high-temperature detection. This heating method is mainly carried out through the heat transfer of the gas inside the high-temperature detection tank, which results in different temperatures in different regions inside the high-temperature detection tank, and thus different coating test pieces at different positions inside the high-temperature detection tank are heated differently, leading to errors in the detection results. In view of this, the utility model proposes a high-temperature resistant testing device for ceramic coatings. Content of the Utility Model

[0005] The utility model proposes a high-temperature resistant testing device for ceramic coatings, which solves the problem that the detection results have errors due to different heating temperatures of different coating test pieces during high-temperature detection.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0023] As Figures 1 to 5 shown, this embodiment proposes a high-temperature test device for ceramic coatings, including a high-temperature detection tank 1. A heater 5 is fixedly connected to the bottom wall inside the high-temperature detection tank 1. A rotating sleeve 2 is rotatably connected inside the high-temperature detection tank 1. An installation mechanism 3 is arranged on the outer side of the rotating sleeve 2. The installation mechanism 3 includes a movable frame 31 for placing a plurality of coating test pieces 4. The movable frame 31 is slidably connected to the outer wall of the rotating sleeve 2. A sliding seat 32 is slidably connected inside the rotating sleeve 2. A chute 33 matching the sliding seat 32 is provided on the side wall of the installation sleeve 38. The sliding seat 32 can slide in the vertical direction along the chute 33. A plurality of connecting rods 34 evenly distributed at equal angles around the sliding seat 32 are fixedly connected to the outer edge of the sliding seat 32. The bottom ends of the plurality of connecting rods 34 are all fixedly connected to the movable frame 31. A first spring 35 is sleeved inside the sliding seat 32. The bottom end of the first spring 35 abuts against the bottom wall inside the rotating sleeve 2, and the top end of the first spring 35 abuts against the sliding seat 32. A movable rod 36 concentric with the rotating sleeve 2 is fixedly connected to the top of the sliding seat 32. The movable rod 36 penetrates the rotating sleeve 2 and extends above the rotating sleeve 2. A handle 37 is fixedly connected to the top of the movable rod 36. An installation sleeve 38 is rotatably connected to the movable rod 36. A positioning component 39 for positioning the installation sleeve 38 is arranged at the top end of the rotating sleeve 2.

[0024] By placing a plurality of coating test pieces 4 on the movable frame 31, then starting the heater 5 to increase the temperature inside the high-temperature detection tank 1, and then operating the handle 37 to rotate the movable rod 36, this causes the sliding seat 32 to drive the rotating sleeve 2 and the movable frame 31 to rotate in the horizontal direction, so that all the coating test pieces 4 rotate circumferentially on the movable frame 31, thereby enabling all the coating test pieces 4 to continuously change positions, making the temperature of all the coating test pieces 4 the same, further ensuring that the detected temperature parameters are the same, and thus improving the accuracy of the final detection result.

[0025] Further, a plurality of placing and taking slots 6 for placing and taking the coating test pieces 4 are formed in the top of the high-temperature detection tank 1. Covers 7 are hinged to the tops of the placing and taking slots 6. Linkage members 30 for cooperating with the mounting sleeve 38 to translate in the vertical direction to drive the covers 7 to open and close are arranged on the tops of the plurality of covers 7. The linkage member 30 includes a first connecting rod 301. One end of the first connecting rod 301 is hinged to the corresponding cover 7. The other end of the first connecting rod 301 is hinged to a second connecting rod 302. The end of the second connecting rod 302 far from the first connecting rod 301 is rotatably connected to a mounting seat 303. The mounting seat 303 is fixedly connected to the outside of the mounting sleeve 38. The coating test pieces 4 are placed on the movable frame 31 through the placing and taking slots 6. Then, the handle 37 is pressed downward to make the movable rod 36 move downward, which makes the mounting sleeve 38 and the movable frame 31 move downward synchronously. At the same time, all the second connecting rods 302 apply pressure to the first connecting rod 301, so that the first connecting rod 301 drives all the covers 7 to rotate to cover the corresponding placing and taking slots 6. Then, the mounting sleeve 38 is positioned by the positioning assembly 39 to determine the vertical position of the mounting sleeve 38, so that the coating test pieces 4 are subjected to high-temperature detection in the sealed high-temperature detection tank 1.

[0026] Further, the positioning assembly 39 includes two parallel limiting plates 391. Both of the two limiting plates 391 are fixedly connected to the movable rod 36. The two limiting plates 391 are respectively located at both ends of the mounting sleeve 38. An annular plate 392 is fixedly connected to the bottom of the mounting sleeve 38. A partition plate 394 that abuts against the limiting plate 391 is fixedly connected to the top end inside the mounting sleeve 38. A positioning member 393 for limiting the annular plate 392 to separate from the mounting sleeve 38 is arranged at the top end outside the mounting sleeve 38. The diameter of the limiting plate 391 is larger than the inner diameter of the mounting sleeve 38. The outer diameter of the annular plate 392 is smaller than the inner diameter of the rotating sleeve 2. The positioning member 393 includes a sliding rod 3931 penetrating through the side wall of the rotating sleeve 2. The sliding rod 3931 is slidably connected to the side wall of the rotating sleeve 2. One end of the sliding rod 3931 is fixedly connected to a positioning block 3932. The positioning block 3932 abuts against the top wall of the annular plate 392. The other end of the sliding rod 3931 is fixedly connected to a pulling block 3933. A receiving groove 3934 that slidably cooperates with the positioning block 3932 is formed in the inner wall of the rotating sleeve 2. A second spring 3935 is sleeved on the sliding rod 3931. One end of the second spring 3935 abuts against the inner wall of the receiving groove 3934. The other end of the second spring 3935 abuts against the positioning block 3932.

[0027] Working principle: Place each coating test piece 4 on the movable frame 31 through the pick-and-place slot 6. Then, pull the pull block 3933 outwards to make the sliding rod 3931 slide, so that the positioning block 3932 is fully engaged with the receiving slot 3934. At this time, the second spring 3935 is compressed to store potential energy. Then, press the handle 37 downwards to make the movable rod 36 move downwards, which makes the mounting sleeve 38 and the movable frame 31 move downwards synchronously. At the same time, all the second connecting rods 302 apply pressure to the first connecting rod 301, so that the first connecting rod 301 drives all the cover plates 7 to rotate to cover the corresponding pick-and-place slots 6. At this time, the sliding seat 32 moves downwards to apply pressure to the first spring 35 to compress and store potential energy. Finally, release the pull block 3933 to make the second spring 3935 release potential energy, which makes the sliding rod 3931 slide in the reverse direction, and also makes the positioning block 3932 slide to the initial position. At this time, the positioning block 3932 abuts against the top wall of the annular plate 392, so that the annular plate 392 is restricted from moving in the vertical direction to determine the vertical position of the mounting sleeve 38, thereby determining the position of the movable frame 31. Then, start the heater 5 to increase the temperature inside the high-temperature detection tank 1. Then, operate the handle 37 to make the movable rod 36 rotate, which makes the sliding seat 32 drive the rotating sleeve 2 and the movable frame 31 to rotate in the horizontal direction, and also makes all the coating test pieces 4 rotate circumferentially on the movable frame 31, so that all the coating test pieces 4 can continuously transfer positions, making all the coating test pieces 4 receive the same heating temperature, thereby ensuring the same detected temperature parameters, and improving the accuracy of the final detection result;

[0028] After the detection is completed, pull the pull block 3933 outwards to make the sliding rod 3931 slide, so that the positioning block 3932 is fully engaged with the receiving slot 3934. At this time, the positioning block 3932 is disengaged from the annular plate 392, so that the first spring 35 releases potential energy, which makes the sliding seat 32 bounce upwards, and also makes the movable frame 31 move upwards to convey all the coating test pieces 4 to the position of the pick-and-place slot 6. At the same time, the first connecting rod 301 pulls the cover plate 7 upwards to open it, so that the coating test pieces 4 can be directly taken out from the pick-and-place slot 6 for observation, thereby obtaining the detection result.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
