Description

Technical Field

[0001] This utility model relates to the technical field of bushing testing equipment, specifically to a bushing testing device. Background Technology

[0002] Bushings are an indispensable part of automotive parts manufacturing and assembly. To ensure the quality of subsequent products and smooth assembly, the size and shape of bushings must meet processing requirements. Therefore, bushings must be inspected for size and appearance after production, and unqualified products must be rejected.

[0003] Existing bushing inspection methods are mostly manual, requiring tools to measure the inner and outer diameters of the bushing to determine if the dimensions meet requirements. Then, the upper and lower end faces and outer peripheral walls of the bushing are inspected to reject products that fail to meet appearance standards. However, this inspection method is inefficient and cannot meet the needs of mass production of bushings. Furthermore, manual inspection is prone to inaccuracies, affecting product quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a device that can automatically inspect the size and appearance of bushings.

[0005] The technical solution of this utility model is to provide a bushing detection device with the following structure: The device includes a frame and a feeding track, a traversing assembly, a first detection assembly, and a second detection assembly mounted on the frame. The feeding track is used to transport the bushings to be inspected. The traversing assembly is used to move the bushings transported by the feeding track to the detection station of the first detection assembly, and to move the bushings at the detection station of the first detection assembly to the detection station of the second detection assembly. The first detection assembly is used to inspect the inner diameter and upper and lower end faces of the bushings, and the second detection assembly is used to inspect the outer diameter and outer peripheral wall of the bushings.

[0006] With the above structure, the bushing detection device of this utility model has the following advantages compared with the prior art: This invention uses a transverse component to move the bushing conveyed by the feeding track to the first detection component to detect the inner diameter and upper and lower end faces of the bushing. Then, the transverse component moves the bushing to the second detection component to detect the outer diameter and outer peripheral wall of the bushing. The entire detection process is fully automated, requiring no manual operation, resulting in high component detection efficiency and ensuring the detection accuracy of the bushing.

[0007] Preferably, the first detection component includes two first detection stages spaced apart on a frame. Two first supports are positioned on one side of each first detection stage on the frame. A first detection camera is mounted on each first support, positioned directly above the corresponding first detection stage, for capturing images of the upper surface of the bushing on the first detection stage. The bushing is placed flat on the first detection stage, and the first detection camera captures images from above, clearly detecting the inner diameter and upper surface appearance of the bushing. The two first detection cameras operate separately; one detects the inner diameter of the bushing, and the other detects the upper surface appearance.

[0008] Preferably, the first bracket is provided with a vertically upward extending slide rail, and a slide block is slidably connected to the slide rail. The first detection camera is installed on the corresponding slide block, so that the height of the first detection camera can be adjusted as needed to ensure detection accuracy.

[0009] Preferably, the first testing platform is provided with a support plate made of transparent material, and the bushing is placed on the support plate of the first testing platform; a second testing camera is provided on the frame below one of the first testing platforms, and the second testing camera is used to photograph the lower end face of the bushing through the support plate. Since the two first testing cameras respectively detect the inner diameter and the appearance of the upper end face of the bushing, but the appearance of the lower end face of the bushing cannot be detected, the second testing camera is set below the first testing platform, and the appearance of the lower end face of the bushing can be clearly photographed through the transparent support plate.

[0010] Preferably, the second detection component includes two second detection tables spaced apart on a frame. Two second supports are provided on one side of the second detection tables on the frame. The second supports are equipped with third detection cameras. The two third detection cameras are used to photograph the outer peripheral wall of the bushing on the corresponding second detection table, and to detect the outer diameter and appearance of the outer peripheral wall of the bushing, respectively.

[0011] Preferably, the second inspection platform is equipped with a rotating seat for placing the bushing and driving the bushing to rotate circumferentially. Since the third inspection camera is located on one side of the second inspection platform, it can only capture one side of the bushing. Therefore, the rotating seat on the second inspection platform can drive the bushing to rotate circumferentially, thereby enabling the third inspection camera to capture the shape and size of the entire outer peripheral wall of the bushing.

[0012] Preferably, the lateral movement assembly includes a third support mounted on the frame, a horizontal and vertical movement module mounted on the third support, and a gripper connected to the horizontal and vertical movement module. The gripper is used to grip the bushing, and the horizontal and vertical movement module is used to drive the gripper to move in the horizontal and vertical directions.

[0013] Preferably, a temporary storage platform and a robotic arm are provided on the frame between the feeding track and the transverse component. The robotic arm is used to grip the bushing conveyed by the feeding track and move it to the temporary storage platform.

[0014] Preferably, the two first detection stations and the two second detection stations are arranged at equal intervals along the detection path of the bushing, and the five grippers are arranged at equal intervals along the detection path of the bushing, which can improve the transmission efficiency of the transverse component.

Therefore, they should not be construed as limitations on this utility model. At the same time, the terms "first", "second", etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown; This utility model discloses a bushing inspection device, including a frame 1 and a feeding track 2, a transverse component 3, a first inspection component 4, and a second inspection component 5 disposed on the frame 1. The feeding track 2 is used to transport the bushing to be inspected, and the transverse component 3 is used to move the bushing transported by the feeding track 2 to the inspection station of the first inspection component 4, and to move the bushing at the inspection station of the first inspection component 4 to the inspection station of the second inspection component 5. The first inspection component 4 is used to inspect the inner diameter and upper and lower end faces of the bushing, and the second inspection component 5 is used to inspect the outer diameter and outer peripheral wall of the bushing.

[0023] A temporary storage platform 21 and a robotic arm 22 are provided on the frame 1 between the feeding track 2 and the transverse component 3. The robotic arm 22 is used to grip the bushing conveyed by the feeding track 2 and move it to the temporary storage platform 21.

[0024] The transverse movement assembly 3 includes a third support 31 mounted on the frame 1, a horizontal and vertical movement module 32 mounted on the third support 31, and a gripper 33 connected to the horizontal and vertical movement module 32. The gripper 33 is used to grip the bushing, and the horizontal and vertical movement module 32 is used to drive the gripper 33 to move in the horizontal and vertical directions. The horizontal and vertical movement module 32 includes a horizontal motor and a vertical motor. The horizontal motor is connected to the third support 31, the vertical motor is connected to the output end of the horizontal motor, and the gripper 33 is connected to the output end of the vertical motor. The horizontal and vertical movement module 32 is prior art and will not be described in detail here.

[0025] The first inspection component 4 includes two first inspection tables 41 spaced apart on a frame 1. Two first supports 42 are positioned on one side of each first inspection table 41 on the frame 1. A first inspection camera 43 is mounted on each first support 42, positioned directly above the corresponding first inspection table 41, and is used to photograph the upper surface of the bushing on the corresponding first inspection table 41. The bushing is placed flat on the first inspection table 41, and the first inspection camera 43 photographs from above, clearly detecting the inner diameter and upper surface appearance of the bushing. The two first inspection cameras 43 operate separately; one is used to detect the inner diameter of the bushing, and the other is used to detect the upper surface appearance.

[0026] The first bracket (2) is provided with a vertically upward extending slide rail 421, and a slide block 422 is slidably connected on the slide rail 421. The first detection camera 43 is installed on the corresponding slide block 422, so that the height of the first detection camera 43 can be adjusted as needed to ensure detection accuracy.

[0027] Since the two first detection cameras 43 detect the inner diameter and upper surface appearance of the bushing respectively, but the lower surface appearance of the bushing cannot be detected, the present invention sets the first detection platform 41 into a cylindrical shape and sets a support plate made of transparent material (such as glass) on its top. The bushing is placed on the support plate of the first detection platform 41. A second detection camera 44 is provided on the frame 1 below the second first detection platform 41. The second detection camera 44 can clearly capture the appearance of the lower surface of the bushing through the transparent support plate.

[0028] The second inspection component 5 includes two second inspection tables 51 spaced apart on the frame 1. Two second supports 52 are provided on one side of the second inspection tables 51 on the frame 1. The second supports 52 are equipped with third inspection cameras 53. The two third inspection cameras 53 are used to photograph the outer peripheral wall of the bushing on the corresponding second inspection table 51, and to inspect the outer diameter and appearance of the outer peripheral wall of the bushing respectively.

[0029] Since the third detection camera 53 is located on one side of the second detection table 51, it can only capture one side of the bushing. Therefore, a rotating seat 54 is provided on the second detection table 51. The rotating seat 54 is used to place the bushing and drive the bushing to rotate circumferentially, so that the third detection camera 53 can capture the shape and size of the entire outer peripheral wall of the bushing.

[0030] Two first detection platforms 41 and two second detection platforms 51 are arranged evenly at intervals along the detection path of the bushing. There are five grippers 33, which are also evenly spaced along the detection path of the bushing. With this arrangement, when the first gripper 33 moves the bushing on the temporary storage platform 21 to the first first detection platform 41, the second gripper 33 moves the bushing on the first detection platform 41 to the second first detection platform 41, and the bushing on the second first detection platform 41 is moved to the first second detection platform 51. This process is repeated to complete the transfer of the bushing along the entire detection path in one go, thereby improving the transmission efficiency of the transverse component 3.

[0031] This invention uses a transverse component 3 to move the bushing conveyed by the feeding track 2 to the first detection component 4 to detect the inner diameter and upper and lower end faces of the bushing. Then, the transverse component 3 moves the bushing to the second detection component 5 to detect the outer diameter and outer peripheral wall of the bushing. The entire detection process is fully automated, requiring no manual operation, resulting in high component detection efficiency and ensuring the detection accuracy of the bushing.

[0032] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
