Description

Technical Field

[0001] The invention relates to the technical field of gasket size detection, and in particular to a device for detecting the outer diameter of an automobile gasket. Background Art

[0002] Gaskets are sealing elements placed between static sealing surfaces to prevent fluid leakage. They are commonly used in a variety of manufacturing industries, especially in automobile manufacturing. When high sealing performance is required, higher requirements are placed on the accuracy of the inner and outer diameters of the sealing gaskets.

[0003] Application number CN201920088208.1 provides a micrometer-based gasket outer diameter detection device, comprising a micrometer and a gasket fixture. The fixture comprises a gasket placement platform, a clamping device disposed at the center of the platform, a hydraulic lifting mechanism disposed within the platform, and an inverted frustum disposed on top of the hydraulic lifting mechanism. This device can clamp the gasket from the inside, facilitating precision outer diameter detection using the micrometer gauge.

[0004] However, for the existing technology, especially the above-mentioned technical solution, the gasket will inevitably come into contact with oil and impurities during the processing, which will cause some oil and impurities to adhere to the gasket, especially the outer surface of the gasket. At this time, when the outer diameter of the gasket is measured by a micrometer, the measurement result will be erroneous due to the oil and impurities. Moreover, since the positions of the oil and impurities on the outer surface of the gasket are different, some gaskets of the same specifications will have errors during the inspection process due to oil and impurities, while others will avoid impurities and oil during the inspection process. However, due to the quality problems of the gasket itself, errors will occur in the inspection, making it difficult to unify the quality of gaskets in the same batch after inspection.

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0031] like Figures 1 to 9 The present invention provides a device for detecting the outer diameter of an automobile gasket, comprising a body 1, a detection component 2, a grabbing component 3, a cleaning component 4 and a rotating component 5. The detection component 2 is connected to the body 1 and is used to detect the outer diameter of a gasket 15. The grabbing component 3 is connected to the body 1 in a vertical rotation direction. The detection component 2 is located on one side of the grabbing component 3. The grabbing component 3 is used to drive the gasket 15 to move. The cleaning component 4 is connected to the body 1 and is located below the grabbing component 3. The cleaning component 4 is used to clean the surface of the gasket 15 horizontally and reciprocatingly. The rotating component 5 is connected to the grabbing component 3.

[0032] See also Figures 1 to 4The grabbing component 3 drives the rotating component 5 in the cleaning component 4 to drive the gasket 15 to rotate circumferentially during cleaning. The grabbing component 3 drives the gasket 15 into the cleaning component 4. When the gasket 15 moves inside the cleaning component 4, it rotates circumferentially and contacts the cleaning component 4 that reciprocates horizontally to remove impurities and oil stains on the surface, making it convenient to detect the outer diameter of the gasket 15 through the detection component 2. After the detection is completed, the gasket 15 is manually placed on the conveying device 18 for transportation. The conveying device 18 drives the gasket 15 to move to the surface defect visual inspection device 16 for surface defect detection. The gasket 15 that passes the inspection continues to be transported by the conveying device 18. The gasket 15 that fails the inspection is pushed away from the conveying device by the pushing device 17 and falls into the collection box 19 under the action of gravity.

[0033] It should be noted that, in this embodiment, the specific structures and working principles of the surface defect visual inspection device 16, the pushing device 17 and the conveying device 18 are technical means well known to those skilled in the art and will not be described in detail here.

[0034] There are many specific structures of the detection component 2. This embodiment provides a specific structure of a detection component 2. The detection component 2 includes a first electric slide 21 and a micrometer 22. The first electric slide 21 is vertically fixed on the machine body 1, and the micrometer 22 is fixed on the slider of the first electric slide 21. The detection end of the micrometer 22 is located above the grasping component 3.

[0035] See also Figure 3 and Figure 4 The first electric slide 21 can adjust the height of the micrometer 22 so that the detection end of the micrometer 22 can contact the outer surface of the gasket 15. By rotating the gasket 15, the micrometer 22 can detect the outer diameter of the gasket 15. When the pointer of the micrometer 22 rotates, it means that the outer surface of the gasket 15 is not smooth.

[0036] It should be noted that, in this embodiment, the specific structure and working principle of the dial indicator 22 are technical means well known to those skilled in the art and will not be described in detail here.

[0037] There are many specific structures of the grabbing assembly 3. This embodiment provides a specific structure of a grabbing assembly 3, which includes a vertical plate 31, a main bracket 32, a first motor 33, three connecting seats 34 and three clamping mechanisms 35. The vertical plate 31 is fixedly installed on the body 1, the main bracket 32 is vertically rotatably connected to the vertical plate 31, the first motor 33 is fixedly installed on the vertical plate 31, the output end of the first motor 33 is connected to the axis of the main bracket 32, the three connecting seats 34 are connected to the main bracket 32 in a circular array, and the angle between two adjacent connecting seats 34 is 120 degrees. The clamping mechanisms 35 are respectively vertically rotatably connected to the three connecting seats 34.

[0038] See also Figures 3 to 5 The first motor 33 can drive the main bracket 32 to rotate on the surface of the vertical plate 31. The main bracket 32 can drive the three connecting seats 34 to rotate synchronously when rotating, so that each connecting seat 34 drives the clamping mechanism 35 on its surface to rotate. The clamping mechanism 35 can clamp and fix the gasket 15. The first clamping mechanism 35 cooperates with the detection component 2 to detect the outer diameter of the gasket 15. The second clamping mechanism 35 drives another gasket 15 to enter the cleaning component 4 to clean the outer surface. The third clamping mechanism 35 drives the gasket 15 after detection to unload. At this time, the staff removes the gasket 15 on the third clamping mechanism 35 and places it on the conveyor Device 18, and then the gasket 15 that has not been tested for outer diameter is placed back on the third clamping mechanism 35, and the main bracket 32 is driven to rotate by the first motor 33. At this time, the main bracket 32 can send the original second gasket 15 to the detection end of the micrometer 22 for detection. The original first gasket 15 is tested at this time, and the staff takes and places the new gasket 15, and the original third gasket 15, that is, the replaced gasket 15, can enter the cleaning component 4 for surface cleaning. This embodiment fixes the three gaskets 15 through three clamping mechanisms 35, realizes continuous cleaning and detection of the gasket 15, and greatly improves the efficiency of outer diameter detection of the gasket 15.

[0039] There are many specific structures of the clamping mechanism 35. This embodiment provides a specific structure of the clamping mechanism 35. The clamping mechanism 35 includes a main shaft 351 and two L-shaped clamping jaws 352. The main shaft 351 is rotatably connected to the connecting seat 34. The two L-shaped clamping jaws 352 are elastically connected to the main shaft 351 along the radial direction of the main shaft 351. The angle between the two L-shaped clamping jaws 352 is 180 degrees.

[0040] See also Figure 6 The L-shaped jaws 352 are connected to the main shaft 351 through the second spring 14. When it is necessary to install the gasket 15 between the two L-shaped jaws 352, the two L-shaped jaws 352 are manually squeezed so that each L-shaped jaw 352 can be translated along the radial direction of the main shaft 351 toward the main shaft 351. At this time, the second spring 14 can be compressed, and then the gasket 15 is put between the two L-shaped jaws 352 and the two L-shaped jaws 352 are released. Under the elastic force of the second spring 14, static friction can be generated between the L-shaped jaws 352 and the inner wall of the gasket 15, thereby achieving fixed clamping of the gasket 15. Since the angle between the two L-shaped jaws 352 is 180 degrees, the static friction on the inner wall of the gasket 15 can be averaged.

[0041] A cleaning pool 6 is provided on the body 1, and the cleaning component 4 is located inside the cleaning pool 6. There are various specific structures of the cleaning component 4. This embodiment provides a specific structure of a cleaning component 4. The cleaning component 4 includes two support rods 41, a base 42 and a cleaning brush 43. The two support rods 41 are fixedly mounted on the inner wall of the cleaning pool 6, the base 42 is horizontally reciprocatingly connected to the two support rods 41, and the cleaning brush 43 is mounted on the base 42. The cleaning brush 43 is located below the grabbing component 3, and the cleaning brush 43 reciprocates horizontally in the cleaning pool 6 to clean the surface of the circumferentially rotating gasket 15.

[0042] See also Figure 3 and Figure 7 At the same time, the cleaning brush 43 can also move horizontally along the axial direction of the support rod 41, so that the cleaning brush 43 can clean the surface of the gasket 15 in different directions, thereby improving the cleaning effect of the gasket 15.

[0043] It should be noted that the cleaning brush 43 can remove the oil stains on the outer surface of the gasket 15 by friction, and the impurities on the surface of the gasket 15 can be removed some time before the cleaning brush 43 contacts it. At this time, a negative pressure dust suction device can be set inside the cleaning pool 6 to collect the removed impurities. In this embodiment, the cleaning brush 43 and the base 42 can be set as a detachable connection structure, such as a bolt connection or a snap connection, so that the cleaning brush 43 can be regularly disassembled to clean the surface oil stains.

[0044] The connecting seat 34 is elastically and movably connected to the main bracket 32. There are many specific structures of the rotating component 5. This embodiment provides a specific structure of the rotating component 5. The rotating component 5 includes a traction shaft 51, a gear 52 and a first rack 53. One end of the traction shaft 51 is coaxially fixedly connected to one end of the main shaft 351, and the other end of the traction shaft 51 passes through the main bracket 32. The gear 52 is fixedly mounted on the surface of the traction shaft 51. The first rack 53 is fixedly mounted on the inner wall of the cleaning pool 6 and can engage with the gear 52. The main bracket 32 drives the gear 52 and the gasket 15 to enter the cleaning pool 6. The connecting seat 34 drives the gear 52 to engage with the first rack 53 to drive the gasket 15 to rotate circumferentially in the cleaning pool 6, and at the same time makes the surface of the gasket 15 contact with the horizontally reciprocating cleaning brush 43.

[0045] See also Figure 3 and Figure 5 The connecting seat 34 and the main bracket 32 are elastically connected by the third spring 20. When the main bracket 32 drives the connecting seat 34 to enter the cleaning pool 6, the connecting seat 34 can drive the gear 52 to contact the smooth section on the first rack 53 first. At this time, the third spring 20 is in a natural state. As the main bracket 32 continues to rotate, the gear 52 gradually contacts the gear tooth segment on the first rack 53. Under the cooperation of the gear tooth segment and the gear 52, the gear 52 can drive the main shaft 351 to rotate on the surface of the connecting seat 34 through the traction shaft 51, and then the main shaft 351 drives the gasket 15 to rotate as a whole through the clamping mechanism 35, and the third spring 20 is in a continuously compressed state at this time. When the gasket 15 revolves to the deepest part of the cleaning pool 6, the third spring 20 is in the state of maximum deformation. As the main bracket 32 continues to rotate, the third spring 20 gradually releases energy, so that the gear teeth segments of the gear 52 and the first rack 53 are always in a meshing state, so that the gasket 15 is always in a self-rotating state before the gear 52 disengages from the gear teeth segments of the first rack 53. Since the first rack 53 is horizontal as a whole, the connecting seat 34 actually drives the gasket 15 to perform horizontal movement in the cleaning pool 6. The gasket 15 can rotate while moving horizontally, so that the gasket 15 is always in contact with the cleaning brush 43 in the cleaning pool 6, thereby achieving the best cleaning effect.

[0046] This embodiment also includes three locking assemblies 7, which are arranged in a circular array between the main bracket 32 and the vertical plate 31. There are various specific structures of the locking assembly 7. This embodiment provides a specific structure of a locking assembly 7, which includes a cylindrical cavity 71, a hemispherical slot 72 and a hemispherical block 73. The cylindrical cavity 71 is opened on the surface of the vertical plate 31, and the hemispherical slot 72 is opened on the surface of the main bracket 32. The end face of the hemispherical block 73 is coaxially elastically connected to the inside of the cylindrical cavity 71, and the spherical surface of the hemispherical block 73 is slidably connected to the inside of the hemispherical slot 72.

[0047] See also Figure 5 and Figure 8 When the first motor 33 drives the main frame 32 to rotate, the main frame 32 can drive the hemispherical slot 72 to rotate synchronously. At this time, the hemispherical slot 72 can apply a thrust along the radial direction of the cylindrical cavity 71 on the hemispherical block 73, and compress the first spring 13 under the action of the hemispherical surface of the hemispherical block 73, so that the hemispherical block 73 can move toward the interior of the cylindrical cavity 71 and compress the first spring 13. As the main frame 32 continues to rotate, when the next hemispherical slot 72 coincides with the axis of the cylindrical cavity 71, the first spring 13 can drive the hemispherical block 73 to re-enter the current hemispherical slot 72, thereby locking the main frame 32 and the vertical plate 31. Through this structure, the main frame 32 can be more stable in the non-rotating state, so that the outer diameter of the gasket 15 can be detected by the micrometer 22, thereby reducing the error.

[0048] There are many specific structures of the drive component 8. This embodiment provides a specific structure of a drive component 8. A drive component 8 is provided inside the cleaning pool 6. The drive component 8 includes a support 81, a drive shaft 82, a slide 83, a swing arm 84, a connecting shaft 85 and a second motor 86. The support 81 is provided inside the cleaning pool 6. One end of the drive shaft 82 is rotatably connected to the support 81. The slide 83 is vertically provided on the side of the base 42. One end of the swing arm 84 is coaxially fixedly connected to one end of the traction shaft 51. The connecting shaft 85 is coaxially fixedly connected to one end of the swing arm 84 and is slidably connected to the inside of the slide 83. The second motor 86 is fixedly mounted on the support 81 and connected to one end of the traction shaft 51.

[0049] See also Figure 7 The second motor 86 can drive the driving shaft 82 to rotate. When the driving shaft 82 rotates, it can drive the swing arm 84 to rotate. When the swing arm 84 rotates, it can drive the connecting shaft 85 to revolve around the axis of the driving shaft 82 as the center of the circle. At this time, the connecting shaft 85 can cooperate with the slide groove 83 to drive the base 42 to perform reciprocating horizontal motion on the surface of the support rod 41.

[0050] Furthermore, an electric push rod 9 is fixedly installed inside the cleaning pool 6, and the output end of the electric push rod 9 is fixedly connected to the bottom of the support 81. Two guide rods 10 are vertically fixedly installed on the inner wall of the cleaning pool 6, and one end of the support rod 41 is slidably connected between the two guide rods 10.

[0051] See also Figure 7 and Figure 9The height of the cleaning brush 43 inside the cleaning pool 6 can be adjusted by setting the electric push rod 9. The base 42 can drive one end of the support rod 41 to slide vertically between the two guide rods 10 when the height is adjusted, so as to limit the horizontal position of the support rod 41, so as to clean gaskets 15 of different specifications. In this embodiment, the two L-shaped jaws 352 are elastically connected to the main shaft 351, so that the two L-shaped jaws 352 can clamp and fix gaskets 15 of different specifications. Finally, the height of the micrometer 22 is adjusted by the first electric slide 21. Through the above process, gaskets 15 of different outer diameters can be detected, thereby improving the overall practicality.

[0052] Furthermore, a second electric slide 11 is vertically fixedly mounted on the machine body 1 , and a second rack 12 is fixedly mounted on the slider of the second electric slide 11 . The second rack 12 can mesh with the gear 52 .

[0053] See also Figure 3 and Figure 4 When detecting the outer diameter of the gasket 15, it is necessary to drive the gasket 15 to rotate so that the micrometer 22 can realize the detection function. In this embodiment, when the gasket 15 to be detected moves to the detection position driven by the main bracket 32, the second electric slide 11 drives the second rack 12 to descend. When the second rack 12 descends, it can drive the main shaft 351 to rotate through the gear 52, and then the main shaft 351 drives the gasket 15 to rotate as a whole through the clamping mechanism 35 to facilitate detection.

[0054] It should be noted that, in this embodiment, the power supply and control systems of the first electric slide 21, the second electric slide 11, the first motor 33 and the second motor 86, as well as the power supply and control systems of the surface defect visual detection device 16, the pushing device 17 and the conveying device 18 are all connected to the control box and controlled by the controller inside the control box. At the same time, the controller is controlled by the background management system to facilitate the overall automatic operation. The specific structure and working principle of the controller are technical means well known to those skilled in the art and will not be elaborated here.

[0055] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which are protected by the present invention.
