Description

Technical Field

[0001] This invention relates to the field of parts inspection, and in particular to a gasket inner diameter inspection device. Background Technology

[0002] A washer is a component placed between a connected part and a nut. It is generally a flat metal ring used to protect the surface of the connected part from scratches by the nut, distribute the pressure of the nut on the connected part, and form a seal between the two parts to prevent leakage of gases or liquids. It is widely used in industries such as machinery, automotive, construction, and chemicals.

[0003] An existing patent (publication number: CN115406392A) discloses a gasket inner diameter testing device, including a worktable. A fixing mechanism is provided on the upper surface of the worktable, and a third testing mechanism is disposed inside the fixing mechanism. A vertical plate is fixedly connected to the rear side of the upper outer surface of the worktable, and a support plate is vertically fixedly connected to the upper end of the vertical plate. A first testing mechanism is disposed on the front side of the support plate, and a housing is fixedly connected to the front end of the support plate. The first testing mechanism includes a rotating shaft located inside the housing. By setting up a fixing mechanism and a third testing mechanism in this invention, the fixing mechanism can fix the gasket while the third testing mechanism inside the fixing mechanism can detect the outer diameter of the gasket. This achieves both fixing of the gasket to prevent displacement during testing and thus avoid affecting the testing quality, and effectively improves the testing function of the device by measuring the outer diameter of the gasket.

[0004] Regarding the aforementioned technologies, this device suffers from low detection efficiency when measuring the inner diameter of gaskets. Summary of the Invention

[0005] The purpose of this application is to provide a gasket inner diameter detection device to solve the problem of improving the detection efficiency of gasket inner diameter.

[0006] The gasket inner diameter detection device provided in this application adopts the following technical solution: A gasket inner diameter detection device includes a first base plate, a second base plate, a third base plate, a calibration device, a material dispensing device, and a collection box. A material dispensing device and a material pushing structure are respectively fixedly arranged on both sides of the upper end of the first base plate. The feeding device includes a first support structure fixed to the upper end of a first base plate, a feeding platform fixedly provided at the upper end of the first support structure, a sliding plate fixedly provided on one side of the feeding platform, and a limit groove fixedly provided at the bottom end of the sliding plate. The pushing structure includes a second support structure fixed to the upper end of the first base plate. An electric push rod is fixedly provided at one end of the second support structure. A connecting plate is fixedly provided at the output end of the electric push rod. A push plate is fixedly provided on one side of the bottom end of the connecting plate. A detection device is fixedly installed on one side of the upper end of the second base plate. The detection device includes a third support structure. A mounting frame is fixedly installed on one side of the upper end of the third support structure. A laser rangefinder is nested inside one end of the mounting frame. A conveying device is fixedly installed on the upper end of the first base plate, the second base plate and the third base plate; By adopting the above technical solution, and by setting up a conveying device, a feeding device, a pushing structure, and a detection device, the material is fed by the operator during use. The pad slides into the limiting groove through a sliding plate. The electric push rod controls the forward and backward movement of the push plate. During the backward movement, the pad falls from the limiting groove onto the conveyor belt of the conveying device. The pad on the conveyor belt is then conveyed by the conveying device. When it is conveyed to the bottom of the laser rangefinder of the detection device, the laser rangefinder detects its circumference (the inner diameter of the pad has a standard). Through this setup, the pad can be automatically detected.

[0007] Preferably, baffles are fixedly provided at the upper edge of both the feeding platform and the slide plate; By adopting the above technical solution and setting baffles to restrict movement, the pads are guaranteed not to shift during sliding.

[0008] Preferably, the calibration device includes a gantry frame fixedly mounted on the upper part of the second base plate. A mounting plate is fixedly mounted on one side of the gantry frame. A servo motor is fixedly mounted on one side of the mounting plate via a fixed seat. The output end of the servo motor extending out of the mounting seat is fixedly connected to a bidirectional lead screw via a coupling. Two sliders are threaded on the outer wall of the bidirectional lead screw. A connecting strip is fixedly mounted on one side of each of the two sliders. A pusher is fixedly mounted at the lower end of each of the two connecting strips. By adopting the above technical solution, the position of the pad will inevitably shift during the conveying process after it is pushed. Through the calibration device, the servo motor is started, which controls the rotation of the bidirectional lead screw, driving the two sliders to move. During the movement, the two push bars are brought closer together. As the push bars approach, they clamp the pad on the conveyor belt and keep it in the center position, ensuring the accuracy of the subsequent detection device.

[0009] Preferably, a bearing seat is fixedly provided on one side of the mounting plate, and a bidirectional lead screw is nested inside the bearing seat at the end away from the servo motor; By adopting the above technical solution, the bearing housing supports the other end of the bidirectional lead screw, ensuring the stable operation of the bidirectional lead screw.

[0010] Preferably, the material distribution device includes a fourth support structure fixedly installed on the upper part of the third base plate, a manifold plate and a fifth support structure fixedly installed on the upper part of the second base plate. A triplet is fixedly installed on one side of the fourth support structure. A solenoid valve is fixedly installed on the upper part of the manifold plate by bolts. A cylinder is fixedly installed on the upper part of the fifth support structure. A fixing plate is fixedly installed on the output end of the cylinder. By adopting the above technical solution, the triplet, the pretreatment unit in the pneumatic system, and the manifold provide centralized air supply and exhaust. The air source is distributed to the solenoid valve through the internal air passage. The solenoid valve drives the internal valve core to move by energizing or de-energizing the solenoid coil, thereby changing the airflow path and controlling the action of the cylinder actuator (such as extension, retraction, start and stop).

[0011] Preferably, a first air pipe is provided between the triplet and the manifold, and a second air pipe is provided between the solenoid valve and the two double-port valves provided at the upper end of the cylinder. By adopting the above technical solution, the triplet is connected to an external air source, and then the air source is transmitted to the manifold through the first air pipe. The manifold transmits the air to the solenoid valve through the internal air circuit. The solenoid valve transmits the air source to the cylinder through the second air pipe. The cylinder is controlled by the solenoid valve to perform actions such as extension and retraction.

[0012] Preferably, a sixth support structure is fixedly provided on the upper end of the third base plate, and a display controller is fixedly provided on one side of the sixth support structure; By adopting the above technical solution, the display controller is a control integration device used to control electrical components. According to the specifications of the gasket to be tested, its inner diameter circumference is calculated. The display structure displays the circumference of the gasket to be tested and the detected inner diameter circumference of the gasket. By comparing the detected circumference with the preset circumference by the controller, the pass rate of the gasket can be quickly detected.

[0013] Preferably, a guide plate is fixedly installed inside one end of the conveying device, and two distributing boxes are nested inside the collection box; By adopting the above technical solution, the tested gaskets fall onto the guide plate after reaching the tail end of the conveyor, and slide into the two material distribution boxes. The two material distribution boxes are used to place the qualified gaskets and the unqualified gaskets respectively.

[0014] Preferably, the bottom ends of the first base plate, the second base plate, and the third base plate are fixedly provided with support frames; By adopting the above technical solution, the support frame supports the overall structure. Beneficial effects

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention provides a gasket inner diameter detection device. Through a conveying device, a feeding device, a pushing structure, and a detection device, in use, the gasket is fed by an operator. The gasket slides into the limiting groove via a sliding plate. An electric push rod controls the forward and backward movement of the push plate. During retraction, the gasket falls from the limiting groove onto the conveyor belt of the conveying device. The gasket on the conveyor belt is then conveyed by the conveying device. When it reaches the bottom of the laser rangefinder of the detection device, the laser rangefinder detects its circumference (the inner diameter of the gasket has a standard). This setup enables automated detection of the gasket.

[0016] 2. This invention provides a gasket inner diameter detection device. Through the calibration device, the position of the gasket will inevitably shift during the conveying process after it is pushed. The servo motor is started to control the rotation of the bidirectional lead screw, which drives the two sliders to move. During the movement, the two push bars are brought closer together. As the push bars approach, they clamp the gasket on the conveyor belt and keep it in the center position, ensuring the accuracy of subsequent detection by the detection device.

[0017] 3. This invention provides a gasket inner diameter detection device. It comprises a detection device, a display controller, and a material distribution device. The display controller presets the circumference of the gasket's inner diameter to be detected on its display structure. After the gasket is detected by a laser rangefinder, the detected inner diameter circumference is transmitted to the display structure. The display controller compares the detected data with the preset data. Qualified gaskets continue to be conveyed on the conveyor belt and, upon reaching the end of the conveyor, fall into the qualified product distribution box via a guide plate. When a gasket is unqualified, the material distribution device is controlled to extend the cylinder's telescopic end. A fixed plate pushes the unqualified gasket away from the center area of ​​the conveyor belt. The unqualified gasket continues to be conveyed on the conveyor belt and, upon reaching the end of the conveyor, falls into the unqualified product distribution box via a guide plate. This device can quickly detect the inner diameter of gaskets and also classify the detected gaskets.

[0018] 4. This invention provides a gasket inner diameter detection device, which basically forms an automated detection system through a feeding device, a pushing structure, a calibration device, a detection device, a sorting device, and a conveying device. Workers feed the gaskets, the pushing structure pushes and controls the quantity fed, the conveying device transports the gaskets, the calibration device corrects the gasket positions, the detection device and display controller work together to detect whether the gaskets are qualified, and the sorting device pushes away unqualified gaskets, finally causing the gaskets to fall into different sorting boxes. All devices are controlled collaboratively by the system to achieve basic automated operation and improve gasket detection efficiency. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0022] Example 1: A washer inner diameter detection device, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a first base plate 1, a second base plate 2, a third base plate 3, a calibration device 6, a material distribution device 8, and a collection box 14. A material feeding device 4 and a material pushing structure 5 are fixedly installed on both sides of the upper end of the first base plate 1. The material feeding device 4 includes a first support structure 401 fixed to the upper end of the first base plate 1, a material feeding platform 402 fixedly installed on the upper end of the first support structure 401, a sliding plate 403 fixedly installed on one side of the material feeding platform 402, and a limit groove 404 fixedly installed at the bottom end of the sliding plate 403. The material pushing structure 5 includes a second support structure 501 fixed to the upper end of the first base plate 1. An electric push rod 502 is fixedly installed at one end of the second support structure 501. A connecting plate 503 is fixedly installed at the output end of the electric push rod 502. A push plate 504 is fixedly installed on one side of the bottom end of the connecting plate 503. A detection device 7 is fixedly installed on one side of the upper end of the second base plate 2. The detection device 7 includes a third support structure 701. A mounting frame 702 is fixedly installed on one side of the upper end of the third support structure 701. A laser rangefinder 703 is nested inside one end of the mounting frame 702. A conveying device 9 is fixedly installed on the upper ends of the first base plate 1, the second base plate 2, and the third base plate 3.

[0023] The technical solution of the above-mentioned device is as follows: by setting up a conveying device 9, a feeding device 4, a pushing structure 5, and a detection device 7, the device is used by the operator to feed the pads. The pads slide into the limiting groove 404 through the sliding plate 403. The electric push rod 502 controls the forward and backward movement of the push plate 504. When the pads are retracted, they fall from the limiting groove 404 onto the conveyor belt of the conveying device 9. The pads on the conveyor belt are conveyed by the conveying device 9. When they are conveyed to the bottom of the laser rangefinder 703 of the detection device 7, the laser rangefinder 703 detects their circumference (the inner diameter of the pads has a standard). Through this setting, the pads can be automatically detected.

[0024] Example 2: A washer inner diameter detection device, referring to... Figure 2 and Figure 5 The calibration device 6 includes a gantry 601 fixedly mounted on the upper end of the second base plate 2. A mounting plate 602 is fixedly mounted on one side of the gantry 601. A servo motor 603 is fixedly mounted on one side of the mounting plate 602 via a fixed seat. The output end of the servo motor 603 extending out of the mounting seat is fixedly connected to a bidirectional lead screw 604 via a coupling. Two sliders 605 are threaded on the outer wall of the bidirectional lead screw 604. A connecting strip 606 is fixedly mounted on one side of each slider 605. A pusher 607 is fixedly mounted at the lower end of each connecting strip 606. A bearing seat 608 is fixedly mounted on one side of the mounting plate 602. The end of the bidirectional lead screw 604 away from the servo motor 603 is nested inside the bearing seat 608.

[0025] The technical solution of the above device is as follows: after the pad is pushed by the calibration device 6, its position will inevitably shift during the conveying process. The servo motor 603 is started, which controls the bidirectional lead screw 604 to rotate, driving the two sliders 605 to move. During the movement, the two push bars 607 are brought closer together. During the process of approaching, the push bars 607 clamp the pad on the conveyor belt and make it in the center position, so as to ensure the accuracy of the subsequent detection device 7.

[0026] Example 3: A washer inner diameter detection device, referring to... Figure 1 , Figure 2 and Figure 6 The material distribution device 8 includes a fourth support structure 801 fixedly mounted on the upper end of the third base plate 3, a manifold 803 fixedly mounted on the upper end of the second base plate 2, and a fifth support structure 805. A triplet 802 is fixedly mounted on one side of the fourth support structure 801. A solenoid valve 804 is fixedly mounted on the upper end of the manifold 803 by bolts. A cylinder 806 is fixedly mounted on the upper end of the fifth support structure 805. A fixing plate 807 is fixedly mounted on the output end of the cylinder 806. The triplet 802 is a pre-treatment unit in the pneumatic system. The manifold 803 provides centralized air supply and exhaust. It distributes the air source to the solenoid valve 804 through an internal air passage. The solenoid valve 804 drives the internal valve core to move by energizing or de-energizing the electromagnetic coil, thereby changing the airflow path and controlling the airflow. The cylinder 806 actuates the movement of the element (such as extension, retraction, start and stop). A first air pipe 808 is provided between the triple unit 802 and the manifold 803. A second air pipe 809 is provided between the two double-ports provided at the upper end of the solenoid valve 804 and the two double-ports provided at the upper end of the cylinder 806. The triple unit 802 is connected to an external air source, and then the air source is transmitted to the manifold 803 through the first air pipe 808. The manifold 803 transmits the air source to the solenoid valve 804 through the internal air circuit. The solenoid valve 804 transmits the air source to the cylinder 806 through the second air pipe 809. The cylinder 806 is controlled by the solenoid valve 804 to perform extension and retraction movements. A sixth support structure 10 is fixedly provided at the upper end of the third base plate 3. A display controller 11 is fixedly provided on one side of the sixth support structure 10.

[0027] The technical effect of the above-mentioned device is that, by setting up a display controller 11 and a material distribution device 8, the circumference calculated from the inner diameter of the gasket to be tested is preset on the display structure of the display controller 11. After the gasket is tested by the laser rangefinder 703, the result of the tested inner diameter circumference of the gasket is transmitted to the display structure. The display controller 11 compares the tested data with the preset data. Qualified gaskets continue to be conveyed on the conveyor belt. After reaching the tail end of the conveyor device 9, they fall into the material distribution box 15 containing qualified products via the guide plate 13. When a gasket is unqualified, the material distribution device 8 is controlled to extend the telescopic end of the cylinder 806. The fixing plate 807 pushes the unqualified gasket away from the center area of ​​the conveyor belt. The unqualified gasket continues to be conveyed on the conveyor belt. After reaching the tail end of the conveyor device 9, it falls into the material distribution box 15 containing unqualified products via the guide plate 13. This device can quickly detect the inner diameter of the gasket and also classify the gaskets after the test.

[0028] Example 4: A washer inner diameter detection device, referring to... Figure 1 and Figure 3 Baffles 405 are fixedly installed at the upper edges of the feeding platform 402 and the slide plate 403. A guide plate 13 is fixedly installed inside one end of the conveying device 9. Two distribution boxes 15 are nested inside the collection box 14. Support frames 12 are fixedly installed at the bottom ends of the first bottom plate 1, the second bottom plate 2 and the third bottom plate 3.

[0029] The technical solution of the above device is to limit the movement of the gasket by setting a baffle 405 to ensure that the gasket does not deviate during the sliding process. After the tested gasket reaches the tail end of the conveying device 9, it falls onto the guide plate 13 and slides into the two distribution boxes 15. The two distribution boxes 15 are used to place the qualified gaskets and the unqualified gaskets after testing, respectively. The support frame 12 supports the overall structure.

[0030] It should be noted that when using the feeding device 4, the pads must be placed one by one. After the push plate 504 moves backward and the pads in the limiting groove 404 fall onto the conveyor belt, the electric push rod 502 immediately pushes the push plate 504 forward to close the bottom of the limiting groove 404. Only then can the pads be placed. After the pads are placed, the push plate 504 will not be moved backward immediately. It is necessary to wait a few seconds to control the distance between the two pads. This setting is mainly to ensure that there is enough time for subsequent operations on the pads to ensure the accuracy of the detection. The laser rangefinder 703 is a Leica DISTO™ D810 touch.

[0031] The implementation principle of this application embodiment is as follows: When using this device, the inner diameter and circumference of the gasket to be inspected are first calculated, and the calculated data is imported into the display controller 11. The operator places the gaskets one by one on the feeding platform 402 of the feeding device 4. The baffles 405 on the edges of the feeding platform 402 and the slide plate 403 prevent the gaskets from slipping off. The gaskets slide along the slide plate 403 into the limiting groove 404, waiting to be pushed. The electric push rod 502 drives the push plate 504 to move backward, and the gaskets in the limiting groove 404 fall onto the conveyor belt of the conveying device 9. The push plate 504 immediately moves forward, closing the bottom of the limiting groove 404. At this time, more gaskets can be added into the limiting groove 404. A few seconds are needed before the electric push rod 502 controls the push plate 504 to move backward again to ensure sufficient spacing between the two gaskets on the conveyor belt, avoiding interference in subsequent operations. When the gaskets are conveyed to the calibration device 6, the servo motor 603 starts, driving... The rotating bidirectional lead screw 604 drives the two sliders 605 and the connected push bar 607 to move closer together. The push bar 607 clamps the washer on the conveyor belt and adjusts it to the center position of the conveyor belt to ensure the accuracy of subsequent testing. The calibrated washer is conveyed to the bottom of the laser rangefinder 703 of the testing device 7. The laser rangefinder 703 detects the circumference of the inner diameter of the washer and transmits the data to the display controller 11. The display controller 11 compares the test data with the preset standard. The qualified washer continues to move with the conveyor belt. After reaching the end, it falls into the qualified sorting box 15 in the collection box 14 through the guide plate 13. When it is unqualified, the display controller 11 controls the solenoid valve 804 of the sorting device 8 to act. The cylinder 806 drives the fixed plate 807 to extend and push the unqualified washer to the edge area of ​​the conveyor belt. After reaching the end with the conveyor belt, it falls into the unqualified sorting box 15 through the guide plate 13.

[0032] The feeding device 4, pushing structure 5, calibration device 6, detection device 7, sorting device 8, and conveying device 9 basically form an automated detection system. The feeding device is operated by the staff, and the pushing structure 5 pushes and controls the quantity of feeding. The conveying device 9 transports the gaskets, the calibration device 6 corrects the position of the gaskets, and the detection device 7 and display controller 11 work together to detect whether the gaskets are qualified. The sorting device 8 pushes the unqualified gaskets, and finally the gaskets fall into different sorting boxes 15. All the devices are controlled by the system to achieve basic automated operation and improve the detection efficiency of the gaskets.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
