Description

Technical Field

[0001] This invention relates to the field of rotating shaft inspection technology, and in particular to a multi-station collaborative inspection device and method for rotating shaft parts. Background Technology

[0002] Shaft inspection is a systematic and precise inspection process designed to comprehensively assess the quality and compliance of shaft components. This process typically encompasses the measurement and judgment of critical dimensions, geometric tolerances, and precision. In industrial practice, this process may be performed manually by operators using basic measuring tools such as calipers and dial indicators, or it may be executed using equipment such as roundness testers, optical measuring instruments, or even automated inspection machines. Its core objective is to ensure that each shaft meets the stringent design drawing requirements, guaranteeing its reliability and stability in the final product. When using existing shaft inspection equipment, multiple shafts are usually placed on a conveyor belt. The conveyor belt is used to feed the shafts to the inspection station. The fixture fixes the shafts at the inspection station and measures them with a dial indicator. This allows for the basic data inspection of the shafts and avoids the presence of defective products in the shafts after production. However, in actual use, the shafts are prone to stacking and clogging, which makes it easy for material to get stuck during conveyor belt transportation. This requires frequent manual intervention and machine shutdown for cleaning, reducing the efficiency of shaft inspection. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency for rotating shaft bodies to stack and block each other, leading to material jamming and reduced inspection efficiency. This invention proposes a multi-station collaborative inspection device and method for rotating shaft parts.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design a multi-station collaborative inspection device for rotating shaft parts, including a base frame and a step-down shaft assembly. The step-down shaft assembly includes several connecting strips, which are fixedly connected to the base frame. A cross-groove platform is fixedly connected between each connecting strip. A first electromagnet and a second electromagnet are alternately arranged along the side edge of the cross-groove platform. Several rotating shaft bodies are evenly distributed in the cross-groove platform. An extension platform is fixedly connected to the side of the base frame, and a measuring component for inspecting the rotating shaft body is provided on the extension platform.

[0005] Preferably, a round rod is rotatably connected through the base frame, a servo motor is fixedly connected to the bottom surface of the base frame, the output end of the servo motor is fixedly connected to the round rod, a turntable is fixedly connected to the circumferential side of the round rod, and two sets of first connecting platforms and second connecting platforms are fixedly connected to the surface of the turntable in an alternating manner, and an arc-shaped cover is fixedly connected to both the first connecting platform and the second connecting platform.

[0006] Preferably, an extension plate is fixedly connected to the side of the base frame, and an electric telescopic rod is fixedly connected to the extension plate, with the output end of the electric telescopic rod corresponding to the arc-shaped cover.

[0007] Preferably, the measuring component includes two driven gears, which are symmetrically rotatably disposed within the extension platform. A groove is provided inside the driven gear, and an arc-shaped sliding plate is slidably connected within the groove. A clamping strip is fixedly connected to the arc-shaped sliding plate.

[0008] Preferably, a U-shaped frame is fixedly connected to the driven gear, a threaded rod is rotatably connected to the U-shaped frame, a movable sleeve is slidably connected inside the U-shaped frame, the threaded rod and the movable sleeve are threadedly engaged, and a hinge rod is hinged between the movable sleeve and the arc-shaped slide plate.

[0009] Preferably, a rotating wheel is fixedly connected to the end of the threaded rod.

[0010] Preferably, a drive rod is rotatably connected through the extension platform, and two drive gears are fixedly connected to the drive rod. The drive gears mesh with the corresponding driven gears. A drive motor is fixedly connected to the side of the extension platform, and the output end of the drive motor is fixedly connected to the drive rod.

[0011] Preferably, the measuring component further includes an L-shaped plate, which is fixedly connected to an extension platform. A slide rail is fixedly connected to the L-shaped plate, and a moving block is slidably connected inside the slide rail. A dial indicator is fixedly connected to the bottom surface of the moving block.

[0012] The present invention proposes a multi-station collaborative inspection device and method for rotating shaft parts. The beneficial effect is that, in use, by alternately switching the first electromagnet and the second electromagnet on and off, after each power-off, the rotating shaft body at the bottom of the cross slot loses the attraction of the magnet and is no longer supported, so it will naturally fall into the inspection station. This can avoid the situation where the supports of each rotating shaft body are stacked on each other during the inspection stage, thus avoiding blockage. This improves the working efficiency of multi-station collaborative inspection of rotating shaft bodies. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-8 This invention relates to a multi-station collaborative inspection device for rotating shaft parts, comprising a base frame 1 and a progressive shaft lowering assembly. The progressive shaft lowering assembly includes several connecting strips 2, which are fixedly connected to the base frame 1. A cross-groove platform 3 is fixedly connected between each connecting strip 2. A first electromagnet 4 and a second electromagnet 5 are alternately arranged along the side edge of the cross-groove platform 3. Several rotating shaft bodies 6 are evenly distributed inside the cross-groove platform 3. An extension platform 15 is fixedly connected to the side of the base frame 1. A measuring component for inspecting the rotating shaft body 6 is provided on the extension platform 15. The measuring component also includes an L-shaped plate 29, which is fixedly connected to the extension platform 15. A slide rail 30 is fixedly connected to the L-shaped plate 29. A moving block 31 is slidably connected inside the slide rail 30. A dial indicator 22 is fixedly connected to the bottom surface of the moving block 31.

[0025] The operation process of this embodiment is as follows: The rotating shaft body 6 is stacked alternately in the cross groove 3. The first electromagnet 4 and the second electromagnet 5 are always kept in a state where one is energized and the other is de-energized. Please refer to the initial state. Figure 2 At this time, the first electromagnet 4 remains energized, while the second electromagnet 5 remains de-energized. The first electromagnet 4 holds the transverse rotating shaft body 6 in attraction, while the longitudinal rotating shaft body 6 is not attracted by the second electromagnet 5, but remains stable due to the support of the transverse rotating shaft body 6. If the energization state of the first electromagnet 4 and the second electromagnet 5 is changed, the second electromagnet 5, after being energized, will attract and fix the longitudinal rotating shaft body 6, while the transverse rotating shaft body 6 will be supported and fixed by the longitudinal rotating shaft body 6. (See reference...) Figure 2 Figure 3 Each time the energization state of the first electromagnet 4 and the second electromagnet 5 is changed, the bottom rotating shaft body 6 will not be attracted by the electromagnets or supported. This allows one of the rotating shaft bodies 6 in the cross slot 3 to fall down after the energization state is changed. By switching the power on and off, the rotating shaft bodies 6 can fall down in an orderly and controllable manner, thereby avoiding the situation where the rotating shaft bodies 6 stack up and cause blockage during the detection process, thus improving the work efficiency of detecting the rotating shaft bodies 6. After the rotating shaft body 6 is lowered, it is moved into the bottom of the slide rail 30. At this time, the dial indicator 22 is pressed against the rotating shaft body 6 and the reading of the dial indicator 22 is zeroed. The rotating shaft body 6 can be rotated, and the dial indicator 22 slides along the circumferential side of the rotating shaft body 6. It can also move the moving block 31 on the slide rail 30, thereby driving the dial indicator 22 to slide along the top of the rotating shaft body 6. This allows for rapid quality inspection of the rotating shaft body 6, thereby further improving the practicality of the device.

[0026] Example 2

[0027] During testing, the rotating shaft body 6 needs to be kept fixed to avoid changes in the contact distance with the dial indicator 22, which could affect the accuracy of the final value. For this purpose, please refer to... Figure 6-8 Based on the first specific embodiment, the measuring component is characterized by comprising two driven gears 16, which are symmetrically rotatably disposed within the extension platform 15. A groove 17 is provided within the driven gear 16, and an arc-shaped slide plate 18 is slidably connected within the groove 17. A clamping strip 19 is fixedly connected to the arc-shaped slide plate 18. A U-shaped frame 20 is fixedly connected to the driven gear 16, and a threaded rod 21 is rotatably connected to the U-shaped frame 20. A movable sleeve 23 is slidably connected within the U-shaped frame 20. The threaded rod 21 and the movable sleeve 23 are threadedly engaged. A hinge rod 24 is hinged between the movable sleeve 23 and the arc-shaped slide plate 18. A rotating wheel 25 is fixedly connected to the end of the threaded rod 21.

[0028] The operation process of this embodiment is as follows: the rotating shaft body 6 is pushed between the two driven gears 16. At this time, the two rotating wheels 25 are rotated. The rotation of the rotating wheels 25 drives the threaded rod 21 to rotate, thereby driving the slider to slide along the slide groove 17. The slider is connected to the arc-shaped slide plate 18 through the hinge 24. At this time, the arc-shaped slider moves, driving the clamping strip 19 to move, thereby clamping the rotating shaft body 6 in the driven gear 16. At this time, the dial indicator 22 can be moved along the top of the rotating shaft body 6. Under the fixing action of the clamping plate, the rotating shaft body 6 can be prevented from shifting during the detection, thereby improving the accuracy of the data when the rotating shaft body 6 is detected.

[0029] Example 3

[0030] When it is necessary to measure the circumferential surface of the rotating shaft body 6, it needs to remain rotating. For this purpose, please refer to [link / reference needed]. Figure 4-7 Based on the first specific embodiment, a round rod 8 is rotatably connected through the base frame 1, a servo motor 7 is fixedly connected to the bottom surface of the base frame 1, the output end of the servo motor 7 is fixedly connected to the round rod 8, a turntable 9 is fixedly connected to the circumference of the round rod 8, two sets of first connecting platforms 10 and second connecting platforms 11 are fixedly connected to the surface of the turntable 9 in an alternating manner, an arc-shaped cover 12 is fixedly connected to both the first connecting platform 10 and the second connecting platform 11, an extension plate 13 is fixedly connected to the side of the base frame 1, an electric telescopic rod 14 is fixedly connected to the extension plate 13, and the output end of the electric telescopic rod 14 corresponds to the arc-shaped cover 12.

[0031] The operation process of this embodiment is as follows: Two driven gears 16 are rotatably mounted on the extension table 15. The rotating rod can be driven to rotate by the drive motor 27. The rotational force drives the two driving gears 28 to rotate. Since the driving gears 28 and the driven gears 16 mesh with each other, the driving gears 28 will drive the rotating shaft body 6 to rotate on the extension table 15. At this time, the dial indicator 22 can measure the circumferential surface of the rotating shaft body 6. When the rotating shaft body 6 falls from the cross groove platform 3, it is possible that the rotating shaft body 6 falls horizontally or vertically. The servo motor 7 can drive the round rod 8 to rotate, and the rotational force drives the various arc-shaped covers 12 to rotate. Please refer to [link / reference]. Figure 4 Regardless of which direction the rotating shaft body 6 falls, it will always fall into the arc-shaped cover 12. At this time, each arc-shaped cover 12 rotates along the axis of the round rod 8, thereby driving the axis of the rotating shaft body 6 to align with the driven gear 16. An electric telescopic rod 14 pushes the rotating shaft body 6 between the two driven gears 16, thus proceeding to the next step of the inspection process, thereby further improving the work efficiency of inspecting the rotating shaft body 6.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
