Description

Technical Field

[0001] This utility model relates to the field of gasket testing technology, specifically to a conical gasket testing mechanism. Background Technology

[0002] Conical washers enhance the stability and reliability of bolted connections through their unique structure. They provide anti-loosening fixation, absorb stress and vibration, compensate for assembly errors, increase load-bearing capacity, and extend service life. They are widely used in automotive engines, transmissions, steel structure connections, pipeline sealing, aerospace equipment, and other applications.

[0003] Among them, announcement number CN222938727U discloses a locking washer testing device, belonging to the field of washer testing technology. It includes a workbench, a mounting base mounted on the top of the workbench, a testing seat embedded in the top of the mounting base, and a positioning clamping assembly inside the testing seat. Positioning clamping plates of the positioning clamping assembly are distributed on the top of the testing seat. A mounting frame mounted on the top of the workbench has a mounting plate movably connected to its surface via a hydraulic cylinder. A pressure sensor is embedded in the bottom of the mounting plate, and the bottom end of the pressure sensor is movably connected to a pressure plate via a quick-connect assembly. This invention can quickly clamp and fix locking washers of different sizes during testing, ensuring testing efficiency. Furthermore, it allows for timely replacement and maintenance of components when the pressure plate is damaged, further improving testing accuracy and ensuring testing effectiveness and efficiency. This device clamps and fixes the gaskets using a positioning clamping assembly, which improves the detection accuracy. However, since gaskets are usually tested in large batches, the device places a single gasket on the testing seat during the testing process. After the test is completed, the gasket needs to be removed before placing the untested gasket. The loading and unloading process is cumbersome, which affects the equipment's testing efficiency and makes it unsuitable for testing large batches of gaskets.

[0004] Therefore, it is necessary to invent a conical gasket detection mechanism to solve the above problems. Utility Model Content

Support frames are fixedly connected to both the left and right sides of the testing platform, and a testing component is installed on the upper end of the right support frame.

[0007] By adopting the above technical solution, the positioner is used to locate the position of the gasket body and move the gasket body precisely to the underside of the detection component, thereby improving the detection accuracy. The conveyor belt drives multiple sets of positioners to move to the right on the surface of the detection platform, placing the gasket body on the upper side of the positioner. This then drives the gasket body to move to the right on the surface of the detection platform, moving it to the underside of the right-side detection component. At this time, the detection component detects the gasket body on the upper side of the positioner. After the detection is completed, the gasket body is moved directly to the right, while another set of gasket bodies is moved to the underside of the detection component for detection, effectively improving the detection efficiency.

[0008] Optionally, the support block is fixedly connected to the surface of the conveyor belt, and the support block has two sets of connecting grooves, one in the front and one in the back.

[0009] By adopting the above technical solution, the connecting groove is L-shaped, and the two sets of connecting grooves are symmetrically distributed.

[0010] Optionally, the detection plate has two sets of first sliding grooves inside, and a second sliding groove is provided on the lower surface of each set of first sliding grooves.

[0012] Optionally, each of the two sets of first sliders has a pressure rod fixedly connected to one end facing away from the other, and the pressure rod is slidably connected to the side wall of the detection plate.

[0013] By adopting the above technical solution, the pressure rod is used to drive the first slider to slide.

[0014] Optionally, each of the two sets of first sliders has two sets of longitudinal limiting grooves inside, the limiting rod is slidably connected to the limiting groove, and one end of the limiting rod is fixedly connected to the side wall of the first sliding groove.

[0015] By adopting the above technical solution, the first slider slides on the surface of the limiting rod through the limiting groove.

[0016] Optionally, the limiting spring is sleeved on the surface of the limiting rod, and the two ends of the limiting spring abut against the end of the first slider and the inner wall of the first groove, respectively.

[0017] By adopting the above technical solution, the limiting rod is used to support the support spring, and the support spring is used to push the first slider outward to position the first slider.

[0018] Optionally, the detection assembly includes a mounting bracket, a hydraulic cylinder, a detection head, and a vision sensor, with the mounting bracket fixedly connected to the upper end of the right-side support frame.

[0019] Optionally, the hydraulic cylinder is fixedly installed at the middle position on the upper surface of the mounting frame, the detection head is fixedly connected to the lower end of the piston rod in the hydraulic cylinder, and vision sensors are fixedly connected to the inner walls of both the front and rear sides of the mounting frame.

[0020] By adopting the above technical solution, the hydraulic cylinder is used to drive the detection head to move up and down to detect the sealing performance of the gasket. At the same time, the vision sensor is used to locate the position of the positioner and the gasket body, and to detect the surface of the gasket body to check for defects.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model utilizes a conveyor belt to move multiple sets of positioners and washer bodies to the right. The positioner locates the position of the washer body and moves it precisely to the underside of the detection component. At this time, the detection component detects the washer body above the positioner, thereby improving detection accuracy. After the detection is completed, the conveyor belt moves the washer body directly to the right and moves another set of washer bodies to the underside of the detection component for detection, achieving uninterrupted detection and effectively improving detection efficiency. 2. This utility model allows the two sets of second sliders to move inward by pressing the pressure rods on both sides. After releasing them, the limiting spring automatically pushes the second sliders outward, thereby locking the second sliders into the interior of the connecting groove and fixing the detection plate on the upper side of the support block. This facilitates the replacement of the detection plate and positioning ring, making it adaptable to the detection of conical washers of different sizes and specifications, thus improving the applicability of the equipment.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1 to 5 The conical gasket testing mechanism shown includes a testing platform 1. A conveyor belt 11 is provided on the surface of the testing platform 1. Multiple sets of positioners 2 are spaced apart on the surface of the conveyor belt 11. Each positioner 2 includes a support block 21, a connecting groove 22, a testing plate 23, a positioning ring 24, a first sliding groove 25, a second sliding groove 26, a first slider 27, a second slider 28, a pressure rod 29, a limiting groove 210, a limiting rod 211, and a limiting spring 212. The positioning ring 24 is fixedly connected to the upper surface of the testing plate 23. A gasket body 4 is placed on the upper side of the testing plate 23. Support frames 12 are fixedly connected to both the left and right sides of the testing platform 1. A testing component 3 is installed on the upper end of the right support frame 12.

[0026] The detection platform 1 is equipped with transmission rollers at both ends, and the two ends of the conveyor belt 11 are respectively connected to two sets of transmission rollers. The transmission rollers are driven to rotate intermittently by the motor, which in turn drives the conveyor belt 11 to rotate intermittently, moving the positioner 2 to the lower side of the detection component 3 at intervals.

[0027] During the testing process, the washer body 4 is placed on the upper side of the testing plate 23, and the washer body 4 is fitted onto the outside of the positioning ring 24. The positioning ring 24 positions the washer body 4 and improves the stability of the washer body 4 during movement and testing, thereby improving the testing accuracy. Then, the motor is started, and the motor drives the conveyor belt 11 to rotate. The conveyor belt 11 drives the positioner 2 and the washer body 4 to move to the right at intervals, moving multiple sets of washer bodies 4 sequentially to the lower side of the testing assembly 3 for testing. After the gasket body 4 under the detection component 3 is detected, the conveyor belt 11 moves it to the right and moves the undetected gasket body 4 on the left to the bottom of the detection component 3, so as to realize feeding while unloading, which effectively improves detection efficiency.

[0028] See Figures 1 to 4 The support block 21 is fixedly connected to the surface of the conveyor belt 11. The support block 21 has two sets of connecting grooves 22 inside. The detection plate 23 has two sets of first sliding grooves 25 inside. The lower surface of each set of first sliding grooves 25 has a second sliding groove 26. The first slider 27 is slidably connected to the first sliding groove 25, and the second slider 28 is slidably connected to the second sliding groove 26. The upper end of the second slider 28 is fixedly connected to the inner end of the first slider 27 on the same side. The lower end of the second slider 28 has an inclined surface. Each of the two sets of first sliders 27 has a pressure rod 29 fixedly connected to one end facing away from the other. The pressure rod 29 is slidably connected to the side wall of the detection plate 23. Each of the two sets of first sliders 27 has two sets of longitudinal limiting grooves 210. The limiting rod 211 is slidably connected to the limiting groove 210. One end of the limiting rod 211 is fixedly connected to the side wall of the first slide groove 25. The limiting spring 212 is sleeved on the surface of the limiting rod 211. The two ends of the limiting spring 212 abut against the end of the first slider 27 and the inner wall of the first slide groove 25, respectively.

[0029] In addition, when inspecting gasket bodies 4 of different batches and sizes, the inspection plate 23 and positioning ring 24 are directly replaced. During the replacement process, the two sets of pressure rods 29 are pressed inward. The pressure rods 29 push the first sliders 27 on both sides inward at the same time. The first sliders 27 drive the second sliders 28 to slide inward, so that the lower end of the second sliders 28 is disengaged from the lower end of the connecting groove 22. At this time, the inspection plate 23 is moved upward to pull the second sliders 28 out of the inside of the connecting groove 22, and the inspection plate 23 and positioning ring 24 are disassembled.

[0030] When installing the replacement detection plate 23, place the detection plate 23 directly on the upper side of the support block 21, align the second slider 28 with the upper side of the connecting groove 22, and press the detection plate 23 down. At this time, since the lower end of the second slider 28 is inclined, during the downward pressing process, the inclined surface cooperates with the side wall of the connecting groove 22, which will drive the two sets of second sliders 28 to slide inward and close together, thereby inserting the second slider 28 into the interior of the connecting groove 22. When the second slider 28 is inserted to the bottom, the limiting spring 212 will push the two sets of first sliders 27 outward simultaneously, thereby driving the two sets of second sliders 28 outward, and locking the lower end of the second slider 28 into the lower end of the connecting groove 22.

[0031] See Figure 1 and Figure 5The detection component 3 includes a mounting frame 31, a hydraulic cylinder 32, a detection head 33, and a vision sensor 34. The mounting frame 31 is fixedly connected to the upper end of the right support frame 12. The hydraulic cylinder 32 is fixedly installed in the middle of the upper surface of the mounting frame 31. The detection head 33 is fixedly connected to the lower end of the piston rod in the hydraulic cylinder 32. Vision sensors 34 are fixedly connected to the inner walls of the front and rear sides of the mounting frame 31.

[0032] Specifically, when the gasket body 4 moves to the lower side of the detection component 3, the hydraulic cylinder 32 pushes the detection head 33 downward through the piston rod, pressing the detection head 33 onto the upper side of the gasket body 4 to detect the sealing performance of the gasket body 4. At the same time, two sets of vision sensors 34 identify the surface of the gasket body 4 to detect whether there are any defects on its surface.

[0033] In another embodiment, a sorting module can be set on the right side of the testing platform 1 to automatically sort the tested gasket bodies 4, thereby further improving the testing efficiency of the equipment.

[0034] The working principle of this utility model is as follows: The conveyor belt 11 drives multiple sets of positioners 2 and washer bodies 4 to move to the right. The positioner 2 positions the washer body 4 and moves it precisely to the underside of the detection component 3. At this time, the detection component 3 detects the washer body 4 on the upper side of the positioner 2, thereby improving the detection accuracy. After the detection is completed, the conveyor belt 11 moves the washer body 4 directly to the right and moves another set of washer bodies 4 to the underside of the detection component 3 for detection, realizing uninterrupted detection and effectively improving detection efficiency. At the same time, pressing the pressure rods 29 on both sides will cause the two sets of second sliders 28 to move inward. After releasing, the limit spring 212 automatically pushes the second sliders 28 outward, locking the second sliders 28 into the interior of the connecting groove 22, fixing the detection plate 23 on the upper side of the support block 21. This facilitates the replacement of the detection plate 23 and the positioning ring 24, making it adaptable to the detection of conical washer bodies 4 of different sizes and specifications, thus improving the applicability of the equipment.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
