Description

Technical Field

[0001] The utility model belongs to the technical field of rubber sealing component detection, and specifically relates to a rapid detection device for rubber sealing components. Background Art

[0002] As an indispensable component of the equipment, the performance of seals directly affects the safety and stability of the entire system. In the process of seal processing, although modern manufacturing technology is quite mature, factors such as material non-uniformity and equipment precision error may still lead to unstable seal performance. In order to ensure that the seals can meet the expected performance after production, performance testing has become an indispensable process.

[0003] At present, there are many kinds of seal detection equipment on the market, such as a rapid detection equipment for rubber seals with application number: CN201922398458.8. The equipment can push the sliding column and hook 2 to hook 1 by controlling the extension of the hydraulic cylinder, so as to facilitate the observation of the horizontal position of hook 1 and hook 2. The threaded rod is driven to rotate up or down by rotating the extension rod, and the hook 1 and hook 2 are adjusted to be flush with each other, and then the rubber seal is put on the hook 1 and hook 2, and the hydraulic cylinder is controlled to contract to drive the sliding column to move away from the vertical rod, so that the hook 1 and hook 2 stretch the rubber seal, so as to facilitate the testing of its stretching degree. The setting of the rotating ring block and the limit ring groove facilitates the rotation of the connecting block, so that the tensile gauge detection end can be kept flush with the hook 2 during the stretching process of the rubber seal, thereby increasing the detection accuracy. The detachable setting of the connecting rod and the vertical rod facilitates the assembly and maintenance of the components. The overall structure is simple, and the phenomenon of the tensile gauge detection end rotating and tilting can be avoided when the height of the tensile gauge is fine-tuned, thereby increasing the detection accuracy and facilitating the rapid detection of the tensile performance of the rubber seal.

[0004] Although the above-mentioned equipment has made significant progress in technology, the current equipment often only supports tensile performance testing, while the evaluation of compressive performance requires additional dedicated equipment. This separate testing method not only increases the complexity and cost of the operation, but may also affect the accuracy and comprehensiveness of the evaluation results;

[0005] In addition, current testing equipment is generally limited to normal temperature environments. This means that when seals face high or low temperature conditions in actual applications, it is impossible to accurately test their tensile properties at these extreme temperatures using existing equipment.

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention, so the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present utility. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the present embodiment in detail, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general scale, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0037] Please refer to the attached Figure 1-Figure 6 As shown, the utility model provides a rapid detection device for rubber seals, including a detection box 1, a computer 2 is fixedly installed on the top surface of the detection box 1, and a base 3 is fixedly installed on the bottom surface of the inner cavity of the detection box 1, wherein the base 3 includes a shell 31 and a rotating seat 32, the shell 31 is fixedly installed on the detection box 1, and the rotating seat 32 is rotatably connected to the inner wall of the shell 31, and also includes:

[0038] A binocular structured light camera 4, which is fixedly mounted on the top surface of the inner cavity of the detection box 1, and an image processor 5 is also fixedly mounted on the binocular structured light camera 4;

[0039] A detection mechanism 6, the detection mechanism 6 is arranged on the base 3;

[0040] Among them, the detection mechanism 6 includes a tensile detection part 61, which is arranged on the top of the base 3 and is used to detect the tensile resistance of the seal. A compressive detection part 62 is also arranged on the periphery of the tensile detection part 61 and is used to detect the compressive resistance of the seal. A driving part 63 is also installed on the base 3.

[0041] In this embodiment, the computer 2 is responsible for receiving and processing data from various components to achieve automated detection and data analysis. The combination of the housing 31 and the rotating base 32 not only ensures the stability of the detection mechanism 6, but also enables the detection mechanism 6 to be rotated and adjusted when necessary;

[0042] The combination of the binocular structured light camera 4 and the image processor 5 enables the device to have high-precision three-dimensional scanning capabilities. The binocular structured light camera 4 obtains the three-dimensional shape information of the seal by emitting structured light and capturing reflected light. This information is then transmitted to the image processor 5 for processing. By comparing with the standard model, it is possible to quickly find out whether the seal has shape defects or size deviations.

[0043] The tensile testing unit 61 measures the deformation and destructive force of the seal during the stretching process by applying a certain tensile force, thereby evaluating its tensile resistance. The compressive testing unit 62 measures the deformation and recovery ability of the seal under pressure by applying pressure, thereby evaluating its compressive resistance. These two testing methods can comprehensively evaluate the performance of the seal and ensure that it has a good sealing effect in practical applications.

[0044] In a preferred embodiment, please refer to Figure 3-Figure 6 The tensile testing part 61 comprises a limit groove 611, which is arranged in a ring shape on the top surface of the rotating seat 32, and a limit block 612 is slidably connected in the limit groove 611, and a round rod 613 is fixedly connected to the limit block 612, and an arc plate 614 is fixedly connected to the upper end of the round rod 613, and a rotating motor 615 is fixedly installed on the bottom surface of the inner cavity of the rotating seat 32, and a disc 616 is fixedly connected to the upper end of the output shaft of the rotating motor 615, and an arc groove 617 is opened on the disc 616.

[0045] In this embodiment, when performing a tensile test, the seal to be tested is first placed on the periphery of the four arc-shaped plates 614, and it is ensured that the seal is in close contact with the top surface of the rotating seat 32. Subsequently, the rotating motor 615 is started to drive the disc 616 to start rotating. During the rotation of the disc 616, the arc-shaped groove 617 on it will contact the round rod 613 and generate a resistance force, thereby causing the limit block 612 on the round rod 613 to slide along the preset limit groove 611. This operation will cause the four arc-shaped plates 614 to stretch the seal in a direction away from each other to perform a tensile test.

[0046] By adjusting the rotation speed of the rotating motor 615, precise control of the tensile test of the seal can be achieved. During the stretching process, the seal will be subjected to a uniform force from the arc plate 614, thereby simulating the stress conditions in the actual working environment. This detection method has obvious advantages over traditional tensile testing machines. First, it can achieve all-round tensile testing of the seal, not just stretching in a certain direction. Secondly, due to the use of the drive of the rotating motor 615 and the design of the disc 616, this detection method has a higher degree of automation and accuracy.

[0047] Next, please refer to Figure 3 The pressure resistance detection unit 62 includes an electric push rod 621, which is fixedly connected to the housing 31. The telescopic end of the electric push rod 621 is fixedly connected to a U-shaped frame 622, and a pressure roller 623 is rotatably connected to the U-shaped frame 622.

[0048] In this embodiment, when performing a tensile test, the seal to be tested is similarly sleeved on the periphery of the four arc plates 614, and the four arc plates 614 are moved away from each other to support the seal and fix the seal. After the seal is stably supported and fixed, the electric push rod 621 is controlled to extend (the extension speed and extension amount of the electric push rod 621 can be adjusted according to the test requirements). When the electric push rod 621 extends, it drives the U-shaped frame 622 connected to it to move. As the U-shaped frame 622 moves, the pressure roller 623 gradually contacts the seal and applies gradually increasing pressure.

[0049] The pressure roller 623 is made of a special rubber material, which can reduce damage to the seal while maintaining sufficient strength.

[0050] Secondly, please refer to Figure 4 The driving part 63 includes a large gear 631, which is fixedly sleeved on the outer wall of the lower end of the rotating seat 32. A driving motor 632 is fixedly installed on the bottom surface of the inner cavity of the shell 31, and a small gear 633 is fixedly connected to the upper end of the output shaft of the driving motor 632.

[0051] In this embodiment, in the operation process of the pressure resistance test, the driving unit 63 is used in conjunction with the driving unit 63. The driving motor 632 is started to drive the pinion 633 to rotate. Subsequently, the rotating seat 32 is smoothly rotated by means of the meshing transmission mechanism between the pinion 633 and the large gear 631. This rotation process ensures the full movement of the seal on the rotating seat 32, and then the pressure resistance test is performed on different positions of the seal. This significantly improves the comprehensiveness and accuracy of the test and ensures the reliability of the test results.

[0052] Next, please refer to Figure 3The top surface of the housing 31 is provided with heating lamps 7 in a circular shape, and the top surface of the rotating base 32 is installed with a temperature sensor 8.

[0053] In this embodiment, during the detection process, the heating lamp 7 can be turned on to heat the sealing ring on the rotating seat 32, and the temperature can be detected in real time by the temperature sensor 8;

[0054] The heating lamps 7 are designed to be distributed in a ring shape on the housing 31, which fully considers the uniformity and efficiency of heating, ensures that the sealing ring can be heated evenly, thereby achieving a better heating effect and facilitating subsequent test operations.

[0055] During the heating process, the temperature sensor 8 will continuously monitor the temperature on the rotating seat 32 and transmit the data in real time to the computer 2. The computer 2 can intelligently adjust the power of the heating lamp 7 according to the received temperature data to maintain a stable heating temperature. This intelligent temperature control not only ensures the stability of the heating effect, but also improves the efficiency and safety of the entire detection process.

[0056] The working principle of this utility is:

[0057] When performing a tensile test, the seal to be tested is first placed on the periphery of the four arc plates 614, and it is ensured that the seal is in close contact with the top surface of the rotating seat 32. Subsequently, the rotating motor 615 is started to drive the disc 616 to start rotating. During the rotation of the disc 616, the arc groove 617 on it will contact the round rod 613 and generate a resistance force, thereby causing the limit block 612 on the round rod 613 to slide along the preset limit groove 611. This operation will cause the four arc plates 614 to stretch the seal in a direction away from each other to test the tensile performance.

[0058] When conducting a tensile test, the seal to be tested is similarly sleeved on the periphery of the four arc plates 614, and the four arc plates 614 are moved away from each other to support the seal and fix the seal. After the seal is stably supported and fixed, the electric push rod 621 is controlled to extend (the extension speed and extension amount of the electric push rod 621 can be adjusted according to the test requirements). When the electric push rod 621 extends, it will drive the U-shaped frame 622 connected to it to move. As the U-shaped frame 622 moves, the pressure roller 623 gradually contacts the seal and applies gradually increasing pressure.

[0059] The pressure roller 623 is made of a special rubber material, which can reduce damage to the seal while maintaining sufficient strength.

[0060] In the operation process of the pressure resistance test, it is used in conjunction with the driving part 63. The driving motor 632 is started to drive the small gear 633 to rotate. Then, the rotating seat 32 is smoothly rotated by means of the meshing transmission mechanism between the small gear 633 and the large gear 631. This rotation process ensures the full movement of the seal on the rotating seat 32, and then the pressure resistance test is performed on different positions of the seal. This significantly improves the comprehensiveness and accuracy of the test and ensures the reliability of the test results.

[0061] The image processor 5 and the computer 2 are connected to the binocular structured light camera 4 to build a complete detection system.

[0062] During the test, the binocular structured light camera 4 will capture images of the seal under different stress states, and analyze the images through the image processor 5. This can more intuitively display the deformation of the seal and help operators to more accurately judge its performance.

[0063] Testing process:

[0064] The sealing ring to be tested is placed on the rotating seat 32 and the detection system is started.

[0065] The camera starts to capture images of the sealing ring and transmits the data to the image processor 5 .

[0066] The image processor 5 performs preprocessing and feature extraction on the image, and calculates the deformation amount of the sealing ring according to the displacement change of the feature points or regions of the sealing ring during the stretching process.

[0067] The computer 2 evaluates the tensile performance of the sealing ring according to the deformation amount and displays the test result. Specifically: the computer 2 further analyzes and processes the deformation amount calculated by the image processor 5 according to the preset algorithm and model.

[0068] By comparing with the standard tensile performance data of the sealing ring, it is evaluated whether the tensile performance of the current sealing ring meets the standard.

[0069] The test results are displayed in real time and the test report can be output as needed.

[0070] Data analysis and processing:

[0071] The computer 2 can record the data of each test, including the deformation amount of the sealing ring, the tensile performance level, etc.

[0072] By analyzing a large amount of test data, we can further understand the performance characteristics of the sealing ring.

[0073] As needed, the test data can be exported as reports or charts to facilitate subsequent analysis and processing.

[0074] It should be added that during the test, the computer system will record the deformation, force and duration of the seal in the process of tension and compression in real time. These data are crucial for evaluating the tensile and compressive properties of the seal. By analyzing these data, we can fully understand the performance of the seal and provide strong support for its application in actual work.

[0075] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
