Description

Technical Field

[0001] This utility model relates to the field of impact resistance testing technology for ceramic tableware, and in particular to an intelligent testing device for the impact resistance of ceramic tableware. Background Technology

[0002] In the ceramic tableware manufacturing industry, impact resistance is one of the core indicators for measuring product quality, directly affecting the product's lifespan and safety. Traditional impact resistance testing of ceramic tableware mostly relies on manually operated drop hammer testing machines, where the impact test is achieved by manually controlling the height of the hammer. However, this method has significant technical drawbacks. From the perspective of impact testing tools, existing equipment uses impact hammers with uniform specifications, making it impossible to adjust the impact contact area according to the different sizes and thicknesses of ceramic tableware (such as plates, bowls, and cups). If the impact area does not match the stress-bearing area of ​​the tableware during testing, it can easily lead to abnormal local stress, causing distorted test data. Furthermore, traditional equipment lacks precise pressure monitoring elements; operators can only estimate the impact force based on the hammer's mass and drop height, making it difficult to quantify and record the actual impact pressure value. This makes it impossible to establish a precise correlation between impact force and the tableware's breakage state, resulting in poor scientific validity and repeatability of the test results. Regarding protection and safety during the testing process, existing equipment generally lacks effective protective mechanisms. Ceramic tableware may shatter upon impact, and the flying fragments not only pose safety hazards to operators but may also damage surrounding components of the testing equipment. Furthermore, flying fragments can interfere with observation and recording during the testing process, making it impossible to accurately capture the instantaneous changes in the tableware's condition upon breakage, thus affecting the analysis of the breakage mechanism. This lack of protection in the testing mode reduces operational safety and restricts the integrity and accuracy of the test data, making it difficult to meet the high-quality testing requirements of modern large-scale ceramic tableware production.

[0003] Therefore, it is necessary to provide an intelligent testing device for the impact resistance of ceramic tableware to solve the above-mentioned technical problems. Utility Model Content

[0004] This invention provides an intelligent testing device for the impact resistance of ceramic tableware, which solves the problems in the background technology. To address the aforementioned technical problems, this utility model provides an intelligent testing device for the impact resistance of ceramic tableware. The device includes a main body with a drive cylinder vertically mounted on its top surface. This drive cylinder serves as a power source, with its bottom end connected to an impact assembly, providing downward driving force. The impact assembly includes a mounting plate and a pressure sensor. The pressure sensor is installed between the drive cylinder and the mounting plate, allowing real-time sensing of pressure changes during the impact process. A first internal threaded hole is formed on the bottom surface of the mounting plate, through which an impact hammer is spirally connected. The outer side of the impact hammer's rod has external threads, facilitating hammer replacement. Multiple impact hammers are available, each with a different bottom cross-sectional area. Operators can select the appropriate hammer based on the ceramic tableware's specifications to ensure the impact area matches the tableware's stress zone, preventing localized stress anomalies. The pressure sensor transmits the monitored pressure signals, providing a basis for subsequent data analysis. Preferably, an electric push rod is installed on the top surface of the device body, located on one side of the drive cylinder. The output end of the electric push rod passes through the top surface of the device body and is connected to a fixing ring. A transparent protective cover is installed at the bottom end of the fixing ring. The electric push rod can drive the fixing ring and the transparent protective cover to rise and fall. During testing, the transparent protective cover descends to cover the testing area, preventing debris from flying, ensuring the safety of the operator and avoiding interference with the testing process. When not in operation, it rises to near the top of the device body, without affecting operation. Preferably, the device body is equipped with a data acquisition and analysis module, which includes a high-speed camera and a data processor. The high-speed camera is installed on the inner wall of the device body, facing the detection area, and can capture the state changes of the ceramic tableware when impacted. The data processor is electrically connected to the high-speed camera and the pressure sensor, and can receive the image data from the high-speed camera and the pressure data from the pressure sensor, and analyze and process this data to establish a correspondence between the impact force and the breakage state of the tableware. Preferably, an operating platform is installed at the bottom of the device body via a support rod. The support rod provides stable support for the operating platform. The operating platform is located in the middle of the device body and directly below the impact component, providing a platform for placing ceramic tableware and facilitating accurate impact testing of the tableware by the impact hammer. Preferably, the device body has a placement seat fixed at the bottom inside. The placement seat can be located in a convenient place such as next to the operating table. The top surface of the placement seat has a second internal threaded hole, which can hold impact hammers of different specifications, providing storage space for spare impact hammers and making it convenient for operators to quickly replace impact hammers according to testing needs. Preferably, multiple support rods are installed, and the multiple support rods are installed at equal distances between the operating table and the device body. The multiple equally distributed support rods can more stably support the operating table, ensuring that the operating table will not shake during the impact detection process and ensuring the stability of the detection.

[0005] Preferably, a controller is installed on the outer surface of the device body. The controller is electrically connected to the drive cylinder, electric push rod, data acquisition and analysis module, etc., and serves as the operation center. It can receive instructions from the operator, control the operation of the drive cylinder and electric push rod, and receive and display the analysis results from the data processor, thereby realizing intelligent control of the entire detection process.

[0006] Compared with related technologies, the intelligent testing device for the impact resistance of ceramic tableware provided by this utility model has the following beneficial effects: Compared with existing technologies, this device uses multiple impact hammers with different bottom cross-sectional areas, and the impact hammers are connected to the mounting plate by threads. This allows for flexible replacement to match the stress area of ​​the tableware, avoiding localized stress anomalies caused by mismatched impact areas and improving the accuracy of test data. At the same time, the pressure sensor can accurately monitor the actual impact pressure value, establish a precise correspondence between impact force and tableware damage state, and improve the scientific nature and repeatability of the test results.

[0007] Compared with existing technologies, the equipment uses an electric push rod to drive the transparent protective cover to rise and fall, which can form an effective protection during the test. This prevents the fragments of the ceramic tableware from flying and causing safety hazards to the operator and damaging surrounding parts after the tableware breaks. At the same time, it ensures that the test process can be clearly observed and recorded, ensuring that the state changes of the tableware at the moment of breakage are captured, thus improving the safety of operation and the integrity and accuracy of the test data.

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] Example 1 Please refer to the following: Figure 1-4 A smart testing device for the impact resistance of ceramic tableware includes a device body 1, which serves as the basic load-bearing structure of the entire device. A drive cylinder 3 is vertically fixed to the top surface of the device body 1 by bolts. The cylinder body of the drive cylinder 3 is tightly fitted to the top surface of the device body 1 to ensure no displacement during operation. The piston rod at the bottom of the drive cylinder 3 is fixedly connected to the top of a pressure sensor 15 in the impact assembly via a flange. This rigid connection ensures stable transmission of driving force. The impact assembly includes a mounting plate 13 and a pressure sensor 15. The bottom of the pressure sensor 15 is fixedly connected to the center of the top surface of the mounting plate 13 by welding, placing the pressure sensor 15 on the center line of the impact force and improving the accuracy of pressure detection. The mounting plate 13 has a first internal threaded hole 14 at the center of its bottom surface. The thread specification of the first internal threaded hole 14 matches the external thread 12 on the outer side of the hammer bar of the impact hammer 11. The impact hammer 11 is detachably connected to the mounting plate 13 by tightening the thread. During installation, the impact hammer 11 should be vertically aligned with the first internal threaded hole 14 and tightened to ensure a firm connection and prevent loosening during impact. The installation sequence of this structure is as follows: first, fix the drive cylinder 3 to the top of the device body 1; then connect the pressure sensor 15 to the piston rod of the drive cylinder 3; next, install the mounting plate 13; and finally, select and install the appropriate impact hammer 11 according to the testing requirements. Multiple impact hammers 11 have different bottom cross-sectional areas, designed to match ceramic tableware of different sizes and thicknesses. When replacing an impact hammer 11, simply unscrew the original impact hammer 11 and screw in the new one, making operation convenient. During operation, the drive cylinder 3 provides downward driving force, which is transmitted to the impact hammer 11 through the pressure sensor 15 and the mounting plate 13. The impact hammer 11 impacts the tableware, and the pressure sensor 15 detects the impact force in real time and converts it into an electrical signal, achieving precise quantification of the impact force. This connection method and structural combination solves the problems of the non-adjustable impact area and inaccurate impact force monitoring in traditional equipment. Through the synergistic effect of the replaceable impact hammer 11 and the pressure sensor 15, the accuracy and scientific nature of the test data are ensured.

[0013] Example 2 Please refer to the following: Figure 1-4 An electric push rod 4 is bolted to the top surface of the device body 1, located on one side of the drive cylinder 3. The cylinder of the electric push rod 4 is parallel to the top surface of the device body 1. The push rod at its output end passes through a through hole on the top surface of the device body 1, with a small gap between the through hole and the push rod to ensure smooth lifting and lowering. The bottom end of the push rod is fixed to the center of the top of the fixing ring 5 by a threaded connection. The inner wall of the fixing ring 5 is fixed to the top edge of the transparent protective cover 6 with glue. The transparent protective cover 6 is made of high-strength acrylic material and is shaped like an inverted funnel.

[0014] The installation sequence is as follows: First, fix the electric push rod 4 to the top of the device body 1; then connect the fixing ring 5 to the push rod; and finally install the transparent protective cover 6. During operation, the electric push rod 4 drives the push rod to extend and retract, causing the fixing ring 5 and the transparent protective cover 6 to rise and fall synchronously. Before testing, the protective cover descends, its bottom edge contacting the bottom of the device body 1 to form a closed testing space. After testing, the protective cover rises to its initial position. This structure, combined with the precise drive of the electric push rod 4 and the closed protection of the protective cover, solves the problem of insufficient protection in traditional equipment, preventing debris from flying while not affecting observation, ensuring operational safety and the smooth progress of the testing process.

[0015] Example 3 Please refer to the following: Figure 1-4 A high-speed camera is fixedly mounted on the inner side wall of the device body 1 using bracket bolts. The lens of the high-speed camera is directly facing the center of the operating table 9 to ensure clear recording of the entire process of the tableware being impacted. A data processor is fixedly mounted on the bottom corner of the device body 1 using bolts. The data processor is electrically connected to the high-speed camera and the pressure sensor 15 via wires. The wires are arranged through pre-designed wire channels inside the device body 1 to avoid clutter affecting the operation of the equipment. During installation, the high-speed camera and data processor are fixed first, followed by circuit connections. In operation, the high-speed camera captures real-time video data of the impact process of the tableware and transmits the data to the data processor. Pressure sensor 15 also transmits detected pressure data to the data processor. The data processor integrates and analyzes both types of data to establish a correlation between impact force and the state of tableware breakage. This structure, through the coordinated work of the high-speed camera and data processor, achieves accurate recording and analysis of the detection process, solving the problem that traditional equipment cannot accurately capture the instantaneous state of breakage and improving the completeness of the detection data.

[0016] Example 4 Please refer to the following: Figure 1-4An operating platform 9 is installed at the bottom of the device body 1 via a support rod 10. The top of the support rod 10 is uniformly fixed to the edge of the bottom surface of the operating platform 9 by welding, and the bottom of the support rod 10 is fixed to the bottom of the device body 1 via bolts. The four support rods 10 are located at the four corners of the operating platform 9, forming a stable support structure.

[0017] During installation, first fix the support rod 10, then install the operating table 9, ensuring that the operating table 9 is placed horizontally. The function of the operating table 9 is to support the ceramic tableware to be tested. Its position is directly below the impact hammer 11, ensuring accurate impact positioning. The rigid support of the support rod 10 prevents the operating table 9 from deforming or shaking when subjected to impact, providing a stable platform for testing and ensuring that the impact force is accurately applied to the tableware.

[0018] Example 5 Please refer to the following: Figure 1-4 The device body 1 has a placement seat 8 fixed to the bottom of the device body 1 near the operating table 9 by bolts. The top surface of the placement seat 8 is evenly provided with a plurality of second internal thread holes 16. The specifications of the second internal thread holes 16 are matched with the external thread 12 of the impact hammer 11. During installation, the placement seat 8 can be directly fixed inside the device body 1. The function of the placement seat 8 is to store the spare impact hammer 11. When the impact hammer 11 is not in use, it is screwed into the second internal threaded hole 16, which saves space and makes it easy to access. This structural design allows operators to quickly replace the impact hammer 11, improves testing efficiency, and ensures that the impact components can be adjusted in a timely manner according to different tableware specifications.

[0019] Example 6 Please refer to the following: Figure 1-4 Multiple support rods 10 are installed, and the multiple support rods 10 are installed at equal distances between the operating table 9 and the device body 1. The support rods 10 are made of metal and have high strength and rigidity. The distance between adjacent support rods 10 is equal, so that the operating table 9 is subjected to uniform force. This equidistant installation logic ensures the stability of the operating table 9. When the impact hammer 11 applies an impact force to the tableware, the impact force is transmitted through the operating table 9 to multiple support rods 10 and then distributed to the device body 1. This avoids excessive local stress that could lead to structural damage and ensures the overall structural stability of the equipment, providing a structural basis for the repeatability and accuracy of the test.

[0020] Example 7 Please refer to the following: Figure 1-4 The controller 7 is fixedly mounted on the outer surface of the device body 1 by bolts. The controller 7 has a display screen and operation buttons on its surface. The internal circuit board is electrically connected to the drive cylinder 3, electric push rod 4, high-speed camera and data processor by wires. The wires are connected through the wiring channel inside the device body 1 to ensure circuit safety. During installation, the controller 7 is fixed first, followed by the circuit connection. The controller 7 serves as the control center of the equipment. Operators send commands via operation buttons, and the controller 7 receives these commands and controls the start, stop, and stroke of the drive cylinder 3, as well as the raising and lowering of the electric push rod 4. Simultaneously, it receives analysis results transmitted from the data processor and displays them on the screen. This structure enables intelligent control of the equipment. Through the coordinated work of the controller 7 and other components, the testing process is automated and precise, meeting the testing needs of modern large-scale production.

[0021] It should be noted that the control circuit of controller 7 can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0022] The working principle of the intelligent testing device for the impact resistance of ceramic tableware provided by this utility model is as follows: When the intelligent testing equipment for the impact resistance of ceramic tableware is in operation, the operator first places the ceramic tableware to be tested on the operating table 9 supported by the support rod 10 inside the main body 1 of the device. Then, according to the size, thickness and other specifications of the tableware, an impact hammer 11 with a suitable bottom cross-sectional area is selected from the placement seat 8. The impact hammer 11 is then spirally connected to the first internal thread hole 14 on the bottom surface of the mounting plate 13 through the external thread 12 on the outer side of the hammer bar, thus completing the assembly of the impact component. Next, the operator starts the device through the controller 7 on the outer surface of the device body 1. After receiving the instruction, the electric push rod 4 pushes the fixed ring 5 and the transparent protective cover 6 at the bottom to descend until the protective cover completely covers the operating table 9 and the tableware above it, forming a closed detection space and preparing for protection. Then, the drive cylinder 3 starts working, and its output pushes the impact component downward. During the process of the impact hammer 11 contacting the ceramic tableware, the pressure sensor 15 monitors the impact pressure value in real time and transmits the data to the data processor in the data acquisition and analysis module 2. Simultaneously, the high-speed camera starts, capturing and recording the impact process and changes in the tableware's state, and synchronously transmits the image data to the data processor. After the impact is complete, the drive cylinder 3 drives the impact assembly to rise, and the electric push rod 4 drives the protective cover to rise. The data processor analyzes and processes the pressure data from the pressure sensor 15 and the image data captured by the high-speed camera to establish a correlation between the impact force and the damage state of the tableware. The operator can obtain the relevant test results through the controller 7. If other sizes of tableware need to be tested, the test operation can be repeated by simply replacing the corresponding impact hammer 11 according to the above steps.

The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the prior art. The mechanical parts and electrical equipment adopt conventional models in the prior art. The circuit connection adopts conventional connection methods in the prior art.
