Description

Technical Field

[0001] This invention relates to the field of chemical or physical analysis, specifically to a rapid strength testing device for ceramic products and its application method. Background Technology

[0002] Testing equipment is an instrument used to evaluate the mechanical properties of ceramic products. It can be used to assess the ability of ceramic products to resist instantaneous impacts, such as ceramic tableware and ceramic valves. By applying instantaneous impact force to ceramic products through a falling ball impact method, the instantaneous impact force is observed to see if the ceramic products break, or to record the relationship between impact energy and the degree of damage. This provides technical insights into testing equipment. The study of the testing equipment revealed the following problems: The testing equipment performs a rapid impact test on ceramic products. After impact, ceramic products are prone to scattering ceramic fragments. The testing equipment can usually only protect against the scattering of ceramic fragments by using a barrier, but it cannot prevent the ceramic fragments from flying upwards. Furthermore, the testing equipment cannot limit and fix the ceramic products to prevent them from shifting during impact while preventing the ceramic products from scattering ceramic fragments. Currently, CN106323781B discloses a ceramic tile rolling strength testing device. This invention features a base as an installation platform, a motor fixed to the base with bolts, and a motor output shaft connected to a gearbox via a belt. A bearing platform is mounted on the output end of the gearbox. The bearing platform is a cube structure, and a ceramic tile model is fixed on it. The model is connected to the bearing platform with cement or adhesive, and two flat steel bars are fixed on the model. A vertical shaft is fixed to the base, is L-shaped, and its support section is perpendicular to the bearing platform. A sleeve is fixed to one end of the vertical shaft. This invention has a novel structure, reasonable design, simple use, and low cost, meeting the requirements for testing the rolling strength of various ceramic tiles used for flooring and filling a gap in the market for ceramic rolling strength testing devices. This invention primarily addresses the problem that testing equipment cannot simultaneously limit and fix ceramic products to prevent them from shifting during impact, thus avoiding the problem of ceramic products moving when struck. Summary of the Invention

[0003] The purpose of this invention is to provide a rapid strength testing device for ceramic products and its application method.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A rapid strength testing device for ceramic products and its application method are disclosed. The device includes a tester with a cantilever beam slidably connected to its upper end, a weight at the lower end of the cantilever beam, a base at the lower end of the tester, and a support plate at the upper end of the base.

[0005] As a further aspect of the present invention: the testing instrument is equipped with a sensor and an electronic timer near the upper end of the cantilever beam, and the sensor and electronic timer are connected to the power circuit via a power line.

[0006] As a further aspect of the present invention: a guide tube is provided at one end of the hammer near the cantilever beam, and an electric telescopic rod is provided at the end of the guide tube. The electric telescopic rod is connected to the power circuit through a power line. The electric telescopic rod drives the hammer to descend and rise rapidly in a vertical direction through the guide tube.

[0007] As a further aspect of the present invention: the bearing plate has sliding grooves on both sides, and the sliding grooves are arranged in a horizontal direction.

[0008] As a further embodiment of the present invention: the two sides inside the bearing plate are slidably connected to limit plates, the two ends of the limit plates extend into the groove of the bearing plate, and a curved ring is embedded in the lower side of the limit plate, with a crossbar passing through the upper end of the curved ring.

[0009] As a further embodiment of the present invention: the limiting plate extends vertically above the bearing plate, and slides horizontally on the inner side of the bearing plate, with the limiting plates arranged in groups of two.

[0010] As a further embodiment of the present invention: a slot is provided on one side of the limiting plate, the bent ring slides vertically inside the slot, the bent ring extends to the outside of the slot, and the crossbar slides vertically inside the slot.

[0011] As a further aspect of the present invention: the bend ring is arranged vertically, the bend ring is arc-shaped, the arc angle is 90-180°, the arched end of the bend ring is on the side away from the limiting plate, the bend ring is made of rubber, and the thickness of the bend ring is 3-6cm.

[0012] As a further aspect of the present invention: the crossbar weighs 500-600g, and when the ceramic product is not squeezed to one side of the bend, the arc angle of the bend is 180° due to the downward weight of the crossbar.

[0013] As a further aspect of the present invention: the upper end of the bearing plate is surrounded by a protective frame, and the upper end of the protective frame is hinged with rotating bearings on both sides. One side of the rotating bearing is sway-connected with a baffle. The two sides of the inside of the protective frame are slidably connected with rotating shafts. The side of the rotating shaft near the baffle is sway-connected with a diagonal rod. A slider is slidably fitted on the outer side of the diagonal rod. The lower end of the slider is provided with a support arm.

[0014] As a further aspect of the present invention: grooves are provided on both sides of the inner wall of the protective frame, the grooves are arranged in a vertical direction, and the rotating shaft is slidably connected inside the grooves.

[0015] As a further aspect of the present invention: the baffle is tilted vertically at 25-90°, and two sets of baffles and rotary bearings are provided. When the baffle swings upward as a whole, the baffle forms a seal on the upper end of the protective frame.

[0016] As a further aspect of the present invention: the rotating shaft slides vertically inside the groove, the end of the inclined rod away from the rotating shaft is connected to the side of the baffle, and the inclined rod swings vertically through the rotating shaft.

[0017] As a further aspect of the present invention: when the baffle is not swinging upward, the rotating shaft is at the lower end of the groove in the inner wall of the protective frame, the inclined rod is inclined downward at 45°, and the inclined rod supports the lower end of the baffle. At this time, the baffle is inclined downward at 25°.

[0018] As a further embodiment of the present invention: the slider is cylindrical, and the slider and the support arm are matched. The support arm extends above the bearing plate, and the lower end of the support arm is inclined in an arc shape with an inclination angle of 45-90°. The lower end of the support arm is inclined and slidably pressed with the limiting plate in a horizontal direction.

[0019] As a further aspect of the present invention, the application method includes the following steps: S1: A ceramic product is placed on the upper end of the bearing plate. The two sides of the ceramic product are pressed to the arched end of the bend ring. The bend ring slides vertically upward on one side of the limiting plate. The overall arc angle of the bend ring decreases. The upper end of the bend ring drives the crossbar to slide upward. S2: Since the crossbar weighs 500-600g, after the ceramic product is placed, the ceramic product cannot continuously squeeze the bend ring. At this time, by using the downward weight of the crossbar, the crossbar can squeeze the upper end of the bend ring downward, and the bend ring can bend back towards the side of the ceramic product on one side of the limiting plate. S3: The electric telescopic rod drives the hammer to descend rapidly in a vertical direction through the guide tube. The hammer strikes the top of the ceramic product. The electronic timer measures the time of the first and second impacts of the hammer on the ceramic product through the sensor. The time interval can be read directly from the electronic timer. The impact strength of the ceramic sample can be calculated by the time interval and the relevant parameters of the hammer. S4: After the hammer strikes the ceramic product quickly, the hammer returns to the lower end of the cantilever beam, the ceramic product shatters, and the ceramic fragments fly upwards and hit the side of the baffle. The baffle swings upwards through the rotating bearing. The tilting swing of the baffle can protect the ceramic fragments inside the protective frame after the hammer strikes. S5: The baffle causes the inclined rod to swing upward. At the same time, the inclined rod causes the rotating shaft to slide upward. The inclined rod tilts upward through the rotating shaft. The slider on the outside of the inclined rod slides synchronously. The slider causes the support arm to slide towards the end of the inclined rod closer to the rotating shaft. S6: The support arm slides away from the limiting plate at this time, which makes it easier for the limiting plate to slide to both sides of the bearing plate, thereby facilitating the cleaning of ceramic fragments on the upper part of the bearing plate. Beneficial effects

[0020] 1. The ceramic product is placed on the upper end of the support plate. The two sides of the ceramic product are pressed against the arched end of the bend ring. The bend ring slides vertically upward on one side of the limiting plate. The overall arc angle of the bend ring decreases. The upper end of the bend ring drives the crossbar to slide upward. Since the weight of the crossbar is 500-600g, after the ceramic product is placed, the ceramic product cannot continuously compress the bend ring. At this time, the downward weight of the crossbar can compress the upper end of the bend ring downward. The bend ring can bend back towards the side of the ceramic product on one side of the limiting plate. Thus, the bend ring can limit and fix the ceramic product according to its size, preventing the ceramic product from shifting on the upper end of the support plate when the hammer falls downward, which would prevent the hammer from accurately striking the upper end of the ceramic product and affecting the subsequent strength test data. 2. When the ceramic product is placed on the upper end of the support plate, the rotating shaft is at the lower end of the groove in the inner wall of the protective frame, and the inclined rod is tilted downward at 45°. The inclined rod supports the lower end of the baffle. At this time, the baffle is tilted downward at 25°. Due to the downward tilt of the inclined rod, the slider is on the side of the inclined rod close to the baffle. The slider presses against one side of the limiting plate through the support arm, and the auxiliary limiting plate limits the ceramic product. 3. After the hammer strikes the ceramic product rapidly, it returns to the lower end of the cantilever beam, causing the ceramic product to shatter. The ceramic fragments fly upwards and hit the side of the baffle. The baffle swings upwards via a rotating bearing. This tilting motion of the baffle protects the ceramic fragments inside the protective frame after the hammer strike, preventing them from flying upwards out of the frame. 4. The baffle causes the inclined rod to swing upward. As the inclined rod drives the rotating shaft to slide upward, the inclined rod tilts upward through the rotating shaft. The slider on the outside of the inclined rod slides synchronously. The slider drives the support arm to slide towards the end of the inclined rod closer to the rotating shaft. At this time, the support arm slides away from the limiting plate, which facilitates the sliding of the limiting plate towards both sides of the bearing plate, thereby facilitating the cleaning of ceramic fragments on the upper part of the bearing plate.

Detailed Implementation

[0031] Please see Figures 1-9 In this embodiment of the invention, Example 1: A rapid strength testing device for ceramic products and its application method, including a tester 1, a cantilever beam 101 slidably connected to the upper end of the tester 1, a weight 102 provided at the lower end of the cantilever beam 101, a base 103 provided at the lower end of the tester 1, and a bearing plate 2 provided at the upper end of the base 103. A sensor and an electronic timer are provided at the upper end of the tester 1 near the cantilever beam 101. The sensor and electronic timer are connected to the power circuit via a power cord. The electronic timer measures the time of the first and second impacts of the hammer 102 on the ceramic product through a sensor. The time interval can be read directly from the electronic timer. The impact strength of the ceramic sample can be calculated by the time interval and the relevant parameters of the hammer 102. The end of the counterweight 102 near the cantilever beam 101 is provided with a guide tube, and the end of the guide tube is provided with an electric telescopic rod. The electric telescopic rod is connected to the power circuit through a power line. The electric telescopic rod drives the counterweight 102 to descend and rise rapidly in the vertical direction through the guide tube. Ceramic products are placed on the upper end of the support plate 2; The bearing plate 2 has grooves on both sides, which are arranged horizontally. Please refer to the instruction manual for details. Figure 7 As shown; Wherein: a ceramic product is placed on the upper end of the bearing plate 2, and the electric telescopic rod drives the hammer 102 to descend rapidly in a vertical direction through the guide tube. The hammer 102 strikes the upper end of the ceramic product. The electronic timer measures the time of the first and second impacts of the hammer 102 on the ceramic product through the sensor. The time interval can be read directly from the electronic timer. The impact strength of the ceramic sample is calculated by the time interval and the relevant parameters of the hammer 102. Example 2: Refer to the attached instruction manual Figures 4-8 It can be seen that the difference between Embodiment 2 and Embodiment 1 is that the two sides inside the bearing plate 2 are slidably connected to the limiting plate 201, the two ends of the limiting plate 201 extend into the groove of the bearing plate 2, and the lower side of the limiting plate 201 is inlaid with a curved ring 203, and the upper end of the curved ring 203 is penetrated by a crossbar 202. Wherein: the limiting plate 201 extends vertically above the bearing plate 2, and slides horizontally on the inner side of the bearing plate 2. The limiting plates 201 are arranged in pairs, as shown in the attached instruction manual. Figure 8 As shown; The limiting plate 201 has a slot on one side, the bent ring 203 slides vertically inside the slot, the bent ring 203 extends to the outside of the slot, and the crossbar 202 slides vertically inside the slot. The sliding direction of the bend ring 203 and the crossbar 202 can be limited by the setting of the slot; The bend ring 203 is set vertically and is arc-shaped with an arc angle of 90-180°. The arched end of the bend ring 203 is located on the side away from the limiting plate 201. The bend ring 203 is made of rubber and has a thickness of 3-6cm. The bend ring 203 is made of rubber. The material of the bend ring 203 allows it to bend and deform in a vertical direction. The thickness of the bend ring 203 is 3-6cm, which can prevent the bending angle of the bend ring 203 from being too large when the thickness is small, thus preventing it from failing to support the crossbar 202. The crossbar 202 weighs 500-600g. When the ceramic product is not squeezed to one side of the bend ring 203, the arc angle of the bend ring 203 is 180° due to the downward weight of the crossbar 202. In this process, the ceramic product is placed on the upper end of the support plate 2, and the two sides of the ceramic product are pressed against the arched end of the bending ring 203. The bending ring 203 slides vertically upward on one side of the limiting plate 201, and the overall arc angle of the bending ring 203 decreases. The upper end of the bending ring 203 drives the crossbar 202 to slide upward. Since the weight of the crossbar 202 is 500-600g, after the ceramic product is placed, the ceramic product cannot continuously press the bending ring 203. At this time, the downward weight of the crossbar 202 can press the upper end of the bending ring 203 downward. The bending ring 203 can bend back towards the side of the ceramic product on one side of the limiting plate 201. Thus, the bending ring 203 can limit and fix the ceramic product according to its size, so as to prevent the ceramic product from shifting on the upper end of the support plate 2 when the hammer 102 falls downward, which would prevent the hammer 102 from accurately striking the upper end of the ceramic product and affecting the subsequent strength test data. Example 3: Refer to the appendix of the instruction manual Figures 4-9 It can be seen that the difference between Embodiment 3 and Embodiments 1 and 2 is that the upper end of the bearing plate 2 is surrounded by a protective frame 3, the upper end of the protective frame 3 is hinged with a rotary bearing 301 on both sides, one side of the rotary bearing 301 is sway-connected with a baffle 302, the two sides of the inside of the protective frame 3 are slidably connected with a rotating shaft 4, the side of the rotating shaft 4 near the baffle 302 is sway-connected with a diagonal rod 401, the outer side of the diagonal rod 401 is slidably fitted with a slider 402, and the lower end of the slider 402 is provided with a support arm 403. The protective frame 3 has grooves on both sides of its inner wall, arranged vertically. The rotating shaft 4 is slidably connected inside the grooves. Please refer to the instruction manual for details. Figure 6 As shown; The baffle 302 is tilted vertically at 25-90°. Two sets of baffles 302 are provided in conjunction with the rotary bearing 301. When the baffle 302 swings upward as a whole, it forms a seal on the upper end of the protective frame 3. Please refer to the instruction manual appendix. Figure 9 As shown; The rotating shaft 4 slides vertically inside the groove, and the end of the inclined rod 401 away from the rotating shaft 4 is connected to the side of the baffle 302. The inclined rod 401 tilts vertically through the rotating shaft 4. When the baffle 302 swings upward due to the splashing of ceramic fragments, the inclined rod 401 tilts and swings vertically through the rotating shaft 4. When the baffle 302 is not swinging upward, the pivot 4 is at the lower end of the groove in the inner wall of the protective frame 3, and the inclined rod 401 is tilted downward at 45°. The inclined rod 401 supports the lower end of the baffle 302. At this time, the baffle 302 is tilted downward at 25°, which avoids the situation where ceramic fragments cannot hit the side of the baffle 302 when the baffle 302 is attached to the inner wall of the protective frame 3 and the ceramic fragments fly upward. The slider 402 is cylindrical and is matched with the support arm 403. The support arm 403 extends above the bearing plate 2, and its lower end is inclined in an arc shape with an inclination angle of 45-90°. The lower end of the support arm 403 slides and presses against the limiting plate 201 in a horizontal direction. (Refer to the attached instruction manual for details.) Figure 7 As shown; When the ceramic product is placed on the upper end of the bearing plate 2, the rotating shaft 4 is located at the lower end of the groove in the inner wall of the protective frame 3. The inclined rod 401 is tilted downward at 45°. The inclined rod 401 supports the lower end of the baffle 302. At this time, the baffle 302 is tilted downward at 25°. Due to the downward tilt of the inclined rod 401, the slider 402 is located on the side of the inclined rod 401 close to the baffle 302. The slider 402 presses against one side of the limiting plate 201 through the support arm 403, and the limiting plate 201 assists in limiting the ceramic product. When the hammer 102 strikes the ceramic product rapidly, the hammer 102 returns to the lower end of the cantilever beam 101, the ceramic product shatters, and ceramic fragments fly upwards and hit the side of the baffle 302. The baffle 302 swings upwards through the rotating bearing 301. The tilting and swinging of the baffle 302 can protect the ceramic fragments inside the protective frame 3 after the hammer 102 strikes, preventing the ceramic fragments from flying upwards out of the protective frame 3 after the hammer 102 strikes. The baffle 302 drives the inclined rod 401 to swing upward. At the same time, the inclined rod 401 drives the rotating shaft 4 to slide upward. The inclined rod 401 tilts upward through the rotating shaft 4. The slider 402 on the outside of the inclined rod 401 slides synchronously. The slider 402 drives the support arm 403 to slide towards the end of the inclined rod 401 closer to the rotating shaft 4. At this time, the support arm 403 slides away from the limiting plate 201, which makes it easier for the limiting plate 201 to slide towards both sides of the bearing plate 2, thereby facilitating the cleaning of ceramic fragments on the upper end of the bearing plate 2. Example

[0032] The application method includes the following steps: S1: A ceramic product is placed on the upper end of the bearing plate 2. The two sides of the ceramic product are pressed to the arched end of the bending ring 203. The bending ring 203 slides upward in a vertical direction on one side of the limiting plate 201. The overall arc angle of the bending ring 203 is reduced. The upper end of the bending ring 203 drives the crossbar 202 to slide upward. S2: Since the crossbar 202 weighs 500-600g, after the ceramic product is placed, the ceramic product cannot continuously squeeze the bending ring 203. At this time, by using the downward weight of the crossbar 202, the crossbar 202 can squeeze the upper end of the bending ring 203 downward, and the bending ring 203 can bend back towards the side of the ceramic product on one side of the limiting plate 201. S3: The electric telescopic rod drives the hammer 102 to descend rapidly in a vertical direction through the guide tube. The hammer 102 strikes the upper part of the ceramic product. The electronic timer measures the time of the first and second impacts of the hammer 102 on the ceramic product through the sensor. The time interval can be read directly from the electronic timer. The impact strength of the ceramic sample can be calculated by the time interval and the relevant parameters of the hammer 102. S4: After the hammer 102 strikes the ceramic product quickly, the hammer 102 returns to the lower end of the cantilever beam 101, the ceramic product shatters, and the ceramic fragments fly upward and hit the side of the baffle 302. The baffle 302 swings upward through the rotating bearing 301. The tilting and swinging of the baffle 302 can protect the ceramic fragments inside the protective frame 3 after the hammer 102 strikes. S5: The baffle 302 drives the inclined rod 401 to swing upward. While the inclined rod 401 drives the rotating shaft 4 to slide upward, the inclined rod 401 tilts upward through the rotating shaft 4. The slider 402 on the outside of the inclined rod 401 slides synchronously. The slider 402 drives the support arm 403 to slide towards the end of the inclined rod 401 that is close to the rotating shaft 4. S6: At this time, the support arm 403 slides away from the side of the limiting plate 201, so that the limiting plate 201 can slide towards both sides of the bearing plate 2, thereby facilitating the cleaning of ceramic fragments on the upper end of the bearing plate 2. Combining the above steps, this ceramic product testing equipment can quickly protect ceramic fragments after testing by using the baffle 302, preventing ceramic fragments from splashing out of the protective frame 3. At the same time, the vertical tilting swing of the baffle 302 drives the inclined rod 401 to swing vertically, and the slider 402 on the outside of the inclined rod 401 can slide synchronously. This allows the support arm 403 to assist the limiting plate 201 in limiting and fixing the ceramic product when it is placed on the upper end of the support plate 2 by squeezing the limiting plate 201.

[0033] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.

At this time, by using the downward weight of the crossbar (202), the crossbar (202) can squeeze the upper end of the bend ring (203) downward, and the bend ring (203) can bend back towards the side of the ceramic product on one side of the limiting plate (201). S3: The electric telescopic rod drives the hammer (102) to descend rapidly in a vertical direction through the guide tube. The hammer (102) strikes the upper part of the ceramic product. The electronic timer measures the time of the first and second impacts of the hammer (102) on the ceramic product through the sensor. The time interval can be read directly from the electronic timer. The impact strength of the ceramic sample is calculated by the time interval and the relevant parameters of the hammer (102). S4: When the hammer (102) strikes the ceramic product quickly, the hammer (102) returns to the lower end of the cantilever beam (101), the ceramic product breaks, and the ceramic fragments fly upward and hit the side of the baffle (302). The baffle (302) swings upward through the rotating bearing (301). Through the tilting swing of the baffle (302), it can protect the ceramic fragments inside the protective frame (3) after the hammer (102) strikes. S5: The baffle (302) drives the inclined rod (401) to swing upward. At the same time, the inclined rod (401) drives the rotating shaft (4) to slide upward. The inclined rod (401) swings upward at an angle through the rotating shaft (4). The slider (402) on the outside of the inclined rod (401) slides synchronously. The slider (402) drives the support arm (403) to slide towards the end of the inclined rod (401) that is close to the rotating shaft (4). S6: The support arm (403) slides away from the limit plate (201) at this time, so that the limit plate (201) can slide towards both sides of the bearing plate (2), thereby facilitating the cleaning of ceramic fragments on the upper end of the bearing plate (2).
