Description

Technical Field

[0001] This utility model relates to the field of parts inspection structures, and in particular to a flexible positioning device for inspecting automotive parts. Background Technology

[0002] In existing technologies, the inspection of automotive components is a crucial step in ensuring the overall safety and performance of a vehicle. This process involves a thorough inspection and evaluation of each component to ensure its performance meets expected standards. Inspection goes beyond a meticulous visual examination of the components' physical appearance; it also includes a series of functional tests. These tests aim to verify whether the components meet the stringent standards and requirements set by the manufacturer, thereby guaranteeing the safety and reliability of the vehicle in real-world use.

[0003] Ring-shaped structural components are a common part shape in the automotive industry, and their inspection methods typically involve setting up a rotating mounting bracket. This bracket securely holds the ring-shaped component in place, allowing it to rotate. During rotation, a series of fixed probes (ultrasonic or infrared probes, etc.) are used to inspect various parts along the circumference. However, due to the extremely high precision requirements during positioning and inspection, a challenge often arises in practice: balancing accuracy and efficiency. This challenge stems primarily from the need to increase inspection speed while ensuring accuracy to meet the demands of large-scale production. Utility Model Content

[0004] The main purpose of this invention is to provide a flexible positioning device for the inspection of automotive parts, which aims to solve the problem that it is difficult to balance accuracy and efficiency when positioning and inspecting ring-shaped parts due to the extremely high requirements for positional accuracy.

[0005] To achieve the above objectives, this utility model provides a flexible positioning device for inspecting automotive parts, used for inspecting ring-shaped parts, comprising:

[0006] The first conveying section has a feeding side plate and a discharging side plate arranged parallel to each other at both ends of its width. The feeding side plate and the discharging side plate have a feeding port and a discharging port arranged opposite each other.

[0007] The first telescopic component has a first limiting block connected to the output end corresponding to the feed port. The free end of the first limiting block is provided with a first notch facing the discharge port. The central angle corresponding to the first notch is between 10 and 90 degrees.

[0008] The second telescopic component is arranged in parallel with the first telescopic component and the output end is connected to the second limiting block. The free end of the second limiting block is provided with a second notch facing the discharge port. The central angle of the second notch is between 10 and 90 degrees. When the first notch and the second notch are concentric, the annular part is clamped. The first notch and the second notch avoid the annular part and are located on one side of the discharge port.

[0009] The second conveying unit is arranged parallel to the first conveying unit in the width direction;

[0010] A rotary drive is correspondingly disposed above the second conveying unit, and the output end of the rotary drive is disposed below and connected to a base. The center of the base is disposed side by side with the discharge port.

[0011] The probe is positioned on the lower surface of the base and points towards the center of the base.

[0012] The first telescopic member and the second telescopic member transfer the annular part at the first conveying part position to the position below the rotation drive.

[0013] Furthermore, the distance between the probe and the center of the base is adjustable.

[0014] Furthermore, the number of probes is two, and they are arranged on the base at a 180-degree interval with the output end of the rotation drive as the center.

[0015] Furthermore, the first telescopic component and the second telescopic component are driven by servo motors.

[0016] Furthermore, the first and second conveying units operate using conveyor belts.

[0017] Furthermore, the base is disc-shaped or rod-shaped.

[0018] Furthermore, the first limiting block is detachably mounted on the first telescopic member; the second limiting block is detachably mounted on the second telescopic member.

[0019] Furthermore, the flexible positioning device also includes a mounting platform, on which the rotation drive is mounted, and the mounting platform receives the discharge port and the second conveying part in the width direction.

[0020] Furthermore, the first conveying unit and the second conveying unit are arranged abutting each other in the width direction.

[0021] Furthermore, a material frame is provided on the side of the second conveying section away from the discharge port.

[0022] The flexible positioning device for automotive parts inspection provided by this utility model decomposes the pushing structure into a first telescopic component and a second telescopic component, thereby achieving the clamping action without interfering with the operation of the first conveying unit. During the clamping process, the positioning action of the ring-shaped part is naturally achieved. When the ring-shaped part is pushed under the rotation drive, it provides the positional basis for the inspection process. The ring-shaped part itself does not need to rotate, so no specific support structure is required; it can be placed on the second conveying unit. Through the operation of the rotation drive, the probe achieves the circumferential inspection process of the ring-shaped part. The positional coordination between the first and second conveying units achieves an efficient working process. Attached Figure Description

[0034] Reference Figures 1 to 6 In one embodiment of this utility model, a flexible positioning device for inspecting automotive parts, used for inspecting annular parts 010, includes:

[0035] The first conveying section 100 has a feeding side plate 110 and a discharging side plate 120 arranged parallel to each other at both ends of its width. The feeding side plate 110 and the discharging side plate 120 are provided with a feeding port 111 and a discharging port 121 facing each other.

[0036] The first telescopic member 200 has a first limiting block 210 connected to the output end corresponding to the feed port 111. The free end of the first limiting block 210 is provided with a first notch 211 facing the discharge port 121. The central angle corresponding to the first notch 211 is between 10 and 90 degrees.

[0037] The second telescopic member 300 is arranged parallel to the first telescopic member 200 and its output end is connected to a second limiting block 310. The free end of the second limiting block 310 is provided with a second notch 311 facing the discharge port 121. The central angle corresponding to the second notch 311 is between 10 and 90 degrees. When the first notch 211 and the second notch 311 are concentric, the annular part 010 is clamped. The first notch 211 and the second notch 311 avoid the annular part 010 and are located on one side of the discharge port 121.

[0038] The second conveying unit 400 is arranged parallel to the first conveying unit 100 in the width direction;

[0039] A rotation drive 500 is correspondingly disposed above the second conveying part 400. The output end of the rotation drive 500 is disposed below and connected to a base 510. The center of the base 510 is arranged side by side with the discharge port 121.

[0040] The probe 600 is disposed on the lower surface of the base 510 and points to the center of the base 510;

[0041] The first telescopic member 200 and the second telescopic member 300 transfer the annular part 010 at the position of the first conveying part 100 to a position below the rotation drive 500.

[0042] In existing technologies, the extremely high requirements for positional accuracy during positioning and detection often present a challenge in practice where precision and efficiency are difficult to balance.

[0043] The flexible positioning device for automotive parts inspection provided in this utility model is used to inspect ring-shaped parts 010.

[0044] The first conveying section 100 has a feeding side plate 110 and a discharging side plate 120 arranged parallel to each other at both ends of its width. The feeding side plate 110 and the discharging side plate 120 have a feeding port 111 and a discharging port 121 arranged opposite to each other. The feeding port 111 is used to provide the insertion area of ​​the pushing device, and the discharging port 121 is the position where the annular part 010 is pushed out.

[0045] The first telescopic member 200 is disposed on the outside of the feeding side plate 110. The output end of the first telescopic member 200 is connected to the first limiting block 210 corresponding to the feeding port 111. During the operation of the first telescopic member 200, its output end passes through the feeding port 111 and the discharge port 121. The free end of the first limiting block 210 is provided with a first notch 211 facing the discharge port 121, and the central angle corresponding to the first notch 211 is between 10 and 90 degrees.

[0046] The second telescopic member 300 is arranged parallel to the first telescopic member 200, and its output end is connected to a second limiting block 310. In the conveying direction of the first conveying section 100, the second telescopic member 300 is located upstream of the first telescopic member 200, and the free end of the second limiting block 310 has a second notch 311 facing the discharge port 121. The central angle corresponding to the second notch 311 is between 10 and 90 degrees. When the first notch 211 and the second notch 311 are concentric, they clamp the annular part 010. The first notch 211 and the second notch 311 are located on one side of the discharge port 121, avoiding the annular part 010. The above configuration of the first notch 211 and the second notch 311 is to enable the feeding action, which will be detailed in subsequent work processes. The first telescopic member 200 and the second telescopic member 300 can be driven by a motor, hydraulically, or pneumatically, etc.

[0047] The second conveyor section 400 is arranged parallel to the first conveyor section 100 in the width direction. The second conveyor section 400 may be arranged close to or spaced apart from the first conveyor section 100 in width. Generally, the conveying direction of the second conveyor section 400 is opposite to that of the first conveyor section 100. The first conveyor section 100 and the second conveyor section 400 are preferably of the type of conveyor belt.

[0048] The rotary drive 500 is positioned above the second conveying section 400, and its output end is positioned below and connected to the base 510. The center of the base 510 is positioned side by side with the discharge port 121, so that the first telescopic member 200 and the second telescopic member 300 can transfer the annular part 010 at the corresponding position on the first conveying section 100 (at the positions of the feed port 111 and the discharge port 121) to the area below the rotary drive 500.

[0049] The probe 600 is positioned on the lower surface of the base 510 and points towards the center of the base 510, so that when the rotation drive 500 is working, the probe 600 can perform detection actions in the circumferential direction of the annular part 010. The probe 600 can operate using ultrasonic detection or infrared detection, etc., and the appropriate selection and replacement can be made according to the detection method.

[0050] During the control process, controllers are set up for the first conveyor 100, the second conveyor 400, the first telescopic component 200, the second telescopic component 300, the rotation drive 500, and the probe 600 to complete the control actions. Specifically, the controllers can be implemented through a preset program in a microcontroller, through real-time detection and control using corresponding sensors, or a combination of both.

[0051] During the work process:

[0052] During the process of receiving the annular part 010, the first telescopic member 200 is in its initial contracted position, and the first limiting block 210 is between the feed port 111 and the discharge port 121, so that the first notch 211 can receive and correct the annular part 010 at the foremost position of the first conveying section 100; the second telescopic member 300 is in its initial contracted position, and the second limiting block 310 needs to be outside the feed port 111, so that the second limiting block 310 will not block the conveying process of the annular part 010 inside the first conveying section 100.

[0053] During the extension drive process, the second telescopic member 300 needs to be driven to extend to a certain position first, with the first limiting block 210 and the second limiting block 310 side by side, so that the first notch 211 and the second notch 311 concentrically clamp the annular part 010; then the first telescopic member 200 and the second telescopic member 300 are driven to extend to a certain position together, so that the annular part 010 passes through the discharge port 121 and reaches below the rotary drive 500 (the probe 600 needs to be in a clearance position). The second notch 311 must be positioned to the side of the discharge port 121 to complete the clamping action, and the first notch 211 must be positioned to the side of the discharge port 121 to complete the retraction action of the first telescopic member 200.

[0054] During the testing process, the second telescopic component 300 and the first limiting block 210 retract to a certain position, and the working drive probe 600 of the rotation drive 500 rotates. At this time, the probe 600 completes the entire testing process.

[0055] When the test result shows that it is normal, the second conveyor 400 starts to work, and the annular part 010 is transferred. Then the first telescopic part 200 and the second telescopic part 300 retract to their initial positions.

[0056] When the test results show an abnormality, the first telescopic member 200 and the second telescopic member 300 are extended further to transfer the second conveying part 400 from the annular part 010, and then the first telescopic member 200 and the second telescopic member 300 are retracted back to their initial positions.

[0057] In summary, the pushing structure is decomposed into a first telescopic member 200 and a second telescopic member 300, thereby enabling the clamping action without interfering with the operation of the first conveying unit 100. During the clamping process, the positioning action of the annular part 010 is naturally achieved. When the annular part 010 is pushed under the rotation drive 500, a positional basis is established for the detection process. The annular part 010 itself does not need to rotate, thus eliminating the need for a specific support structure, which can be placed on the second conveying unit 400. Through the operation of the rotation drive 500, the probe 600 performs a circumferential detection process on the annular part 010. The positional coordination between the first conveying unit 100 and the second conveying unit 400 achieves an efficient working process.

[0058] In one embodiment, the distance between the probe 600 and the center of the base 510 is adjustable.

[0059] In this embodiment, the probe 600 is adjusted on the base 510 to adapt to ring parts 010 of different sizes. For example, if the size of the ring part 010 is increased, the probe 600 is moved away from the center of the base 510. During the fixing process, a guide rail is set in the radial direction of the base 510, so that the probe 600 can slide in the radial direction of the base 510.

[0060] Reference Figure 3 In one embodiment, the number of probes 600 is two, and they are arranged on the base 510 at a distance of 180 degrees from the output end of the rotation drive 500.

[0061] In this embodiment, the number of probes 600 is increased to improve detection efficiency, and the two probes 600 are set 180 degrees apart so that the annular part 010 will not be obstructed when entering the detection position.

[0062] In one embodiment, the first telescopic member 200 and the second telescopic member 300 are driven by servo motors.

[0063] In this embodiment, the first telescopic member 200 and the second telescopic member 300 are driven by servo motors, so that both can achieve precise drive position output.

[0064] Reference Figure 1 In one embodiment, the first conveyor unit 100 and the second conveyor unit 400 operate as a conveyor belt.

[0065] In this embodiment, the first conveyor unit 100 and the second conveyor unit 400 operate as conveyor belts, thereby creating a stable support effect. In a typical conveyor belt structure, the drive belt is driven by an active roller and a passive roller, allowing materials to be stably conveyed on the drive belt.

[0066] In one embodiment, the base 510 is disc-shaped or rod-shaped.

[0067] In this embodiment, two suitable base shapes are limited: the disc-shaped base 510 has higher operational safety, while the rod-shaped base 510 has a simpler structural design.

[0068] In one embodiment, the first limiting block 210 is detachably mounted on the first telescopic member 200; the second limiting block 310 is detachably mounted on the second telescopic member 300.

[0069] In this embodiment, different models of ring parts 010 can be adapted by replacing the first limiting block 210 and the second limiting block 310. The installation method of the first limiting block 210 and the second limiting block 310 can be a pin connection or the like, and there are no specific limitations.

[0070] Reference Figure 5 In one embodiment, the flexible positioning device further includes a mounting platform, on which the rotation drive 500 is mounted, and the mounting platform receives the discharge port 121 and the second conveying part 400 in the width direction.

[0071] In this embodiment, the mounting platform provides a larger operating space, enhancing the flexibility of the rotary drive 500 configuration. The mounting platform may include two layers: the upper layer for mounting the rotary drive 500, and the lower layer for connecting the discharge port 121 to the second conveyor 400.

[0072] In one embodiment, the first conveying unit 100 and the second conveying unit 400 are arranged abutting each other in the width direction.

[0073] In this embodiment, the first conveying section 100 and the second conveying section 400 are abutted together, eliminating the need for other support structures. However, in order to provide space for the rotation drive 500 to rotate, the width of the second conveying section 400 can be set to be relatively large.

[0074] In one embodiment, a material frame is provided on the side of the second conveying section 400 away from the discharge port 121.

[0075] In this embodiment, the abnormal ring-shaped part 010 is received by the material frame. The abnormal ring-shaped part 010 can be pushed out of the second conveying part 400 through the further extension of the first telescopic member 200 and the second telescopic member 300, and finally fall into the material frame.

[0076] In summary, the flexible positioning device for automotive parts inspection provided by this utility model decomposes the pushing structure into a first telescopic member 200 and a second telescopic member 300, thereby enabling clamping without interfering with the operation of the first conveying unit 100. During the clamping process, the positioning of the annular part 010 is naturally achieved. When the annular part 010 is pushed under the rotation drive 500, it provides the positional basis for the inspection process. The annular part 010 itself does not need to rotate, thus eliminating the need for a specific support structure, which can be placed on the second conveying unit 400. Through the operation of the rotation drive 500, the probe 600 performs circumferential inspection of the annular part 010. The positional coordination between the first conveying unit 100 and the second conveying unit 400 achieves an efficient working process.

Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
