Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic finished product testing technology, and in particular to a ceramic finished product thermal stability testing device. Background Technology
[0002] The specific production process of ceramic products is as follows: First, select suitable ceramic raw materials, then crush and grind them into powder and mix them. Next, add water to the mixed raw materials and knead them into clay. Then, place the clay on a potter's wheel and shape it into the basic shape of the blank by hand. Next, use a mold to press the blank into the required shape. Then, place the shaped blank in a ventilated place to dry and remove excess moisture. Later, you can use a knife to carve patterns on the dried blank. Then, apply a layer of glaze to the surface of the blank to increase its gloss and water resistance. Next, put the glazed blank into a kiln to fire it into a ceramic product. After cooling, it can be taken out for quality inspection (heat stability issues). Finally, it can be packaged and stored in a warehouse.
[0003] Because some ceramic products are heated unevenly between their inner and outer layers, resulting in differences in their coefficients of thermal expansion, stress will be generated inside the ceramic product if it is subjected to high external temperatures for a certain period of time, which may lead to cracks. Therefore, it is necessary to conduct high-temperature thermal stability testing on the ceramic products.
[0004] Currently, existing high-temperature thermal stability testing devices for ceramic products generally require manual placement of the testing frame containing the ceramic products into the testing heating chamber. This manual placement method is prone to shaking, which can cause the ceramic products in the testing frame to shake, collide, or even crack, greatly reducing the stability of the ceramic products and their resistance to cracking when placed in the testing heating chamber.

[0012] Furthermore, the wheel grooves are two symmetrical grooves, with an opening at the right end, and the curved surface is located at the corner of the right opening of the wheel groove.
[0013] Furthermore, the top view of the partition is a cross-shaped structure and is set in the detection frame, and four buffer sleeves are symmetrically arranged with open ends.
[0014] Furthermore, the handle is located at the top of the door, the door is a rectangular plate structure and slides with the guide groove, and a sealing strip is provided at the left end of the door.

[0025] 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.
[0026] Reference Figure 1-5 A ceramic finished product thermal stability testing device includes a testing heating chamber 1, a temperature controller 11 and a probe 12 on the testing heating chamber 1, a base frame 4 below the testing heating chamber 1, a cylinder 41 on the base frame 4, a material rack 5 on the cylinder 41, a wheel groove 51 and a curved surface 52 on the material rack 5, a guide groove 2 on the testing heating chamber 1, a chamber door 21 slidably connected in the guide groove 2, a first slot 23 and a second slot 24 on the chamber door 21, a handle 22 on the chamber door 21, a fixed block 3 on the testing heating chamber 1, a locking pin 31 on the fixed block 3, a spring 33 and a smooth layer 34 on the locking pin 31;
[0027] The material rack 5 is equipped with a detection frame 6, and the detection frame 6 is equipped with a first caster 61 and a second caster 62;
[0028] The detection frame 6 is equipped with a partition 7 and a buffer sleeve 71. The locking pin 31 is equipped with a pull handle 32. The smooth layer 34 is a graphite coating layer with a smooth and low-friction layer, which improves the smoothness of the locking pin 31 sliding along the door 21.
[0029] Later, high-temperature crack detection can be performed on the four ceramic products in the internal detection frame 6 through the temperature controller 11, probe 12, and detection heating box 1 (this detection work is existing technology).
[0030] The first caster 61 consists of two symmetrical front and rear casters, and the second caster 62 consists of two symmetrical front and rear casters. Both the first caster 61 and the second caster 62 are located in the wheel groove 51. The first caster 61 is a directional brake wheel, and the second caster 62 is a directional wheel.
[0031] The material rack 5 has an L-shaped structure and its left end face is fixed to the telescopic rod of the cylinder 41. The lower end face of the material rack 5 is horizontally aligned with the lower end face of the inner cavity of the testing heating box 1, ensuring that the horizontal material rack 5 enters the testing heating box 1 as a whole.
[0032] The wheel grooves 51 are two symmetrical ones and open at the right end. The curved surface 52 is set at the corner of the right end opening of the wheel groove 51, so that the two casters can roll and slide to the right from the material rack 5 and fall into the detection heating box 1.
[0033] The top view of the partition 7 is a cross-shaped structure and is set in the detection frame 6. Four buffer sleeves 71 are symmetrically arranged and the upper end is open. The buffer sleeves 71 are made of elastic silicone material, which is heat-resistant and durable, and achieves the buffer protection effect.
[0034] The handle 22 is located at the top of the door 21. The door 21 is a rectangular plate structure and slides with the guide groove 2. The left end of the door 21 is provided with a sealing strip 13, which is made of elastic rubber. When the door 21 is slid and positioned, it achieves a sealing effect on the left end of the testing heating box 1.
[0035] The two ends of the spring 33 are fixedly set to the handle 32 and the fixed block 3 respectively. The locking pin 31 is slidably set with the fixed block 3 and is engaged with the first locking groove 23. The handle 32 is located at the right end of the locking pin 31. The handle 32 has a T-shaped structure. The spring 33 is durable.
[0036] Working method: Place four ceramic finished products into the four matching buffer sleeves 71, then start cylinder 41, which drives the detection frame 6 to move horizontally and stably into the detection heating box 1 via the material rack 5. Stop cylinder 41. At this time, the left end face of the detection frame 6 is vertically aligned with the right end face of the box door 21. Then, hold the handle 22 with one hand and pull the handle 32 to the right with the other hand, which drives the locking pin 31 to move horizontally to the right and out of the first locking groove 23. At this time, the spring 33 is stretched and deformed. Then move the box door 21 downward, which drives the box door 21 to slide down along the guide groove 2. When the right end face of the box door 21 just contacts the right end face of the detection frame 6, stop moving the box door downward. At this time, the right end face of the locking pin 31 also just contacts and limits the right end face of the box door 21 through the smooth layer 34. Then release the brake of the first caster 61. When cylinder 41 is activated, its telescopic rod retracts to the left, causing the material rack 5 to move horizontally to the left. Since the right end of the door 21 is in contact with the right end of the test frame 6 and will not retract to the left from the test heating box 1, the first caster 61 and the second caster 62 can rotate along the wheel groove 51. When the material rack 5 moves horizontally to the left and resets, cylinder 41 is stopped. This allows the test frame 6 with four ceramic products to move horizontally in a stable and flexible manner and be placed into the test heating box 1. Then, the door 21 continues to move downward. When the second slot 24 aligns with the pin 31, the spring 33 pulls back and causes the pin 31 to quickly engage in the second slot 24. This achieves rapid positioning of the door 21, improving the stability of the ceramic products when the test frame is placed in the test heating box and preventing them from colliding and cracking.
[0037] In addition, the locking pin 31 structure with a T-shaped pull handle 32 enables convenient operation by pulling the locking pin 31 horizontally with one hand, thereby improving the ease of locking and positioning the door 21.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
