Description

Technical Field

[0001] This utility model relates to the field of bearing bridge testing technology, and in particular to a modular bearing bridge testing line. Background Technology

[0002] In modern industrial production, bearing bridges are key components of mechanical transmission systems, and their machining quality and assembly precision directly affect the operational stability and service life of the equipment. To ensure that bearing bridge workpieces meet production standards, comprehensive testing of their dimensions, appearance, and performance indicators is required through a professional testing line. With the continuous improvement of automation levels in manufacturing, modular bearing bridge testing lines have gradually become important equipment in the bearing bridge production and testing process due to their ability to flexibly adapt to different production needs and their ease of maintenance and upgrades. These lines can achieve integrated operation of workpiece conveying, positioning, testing, and sorting, significantly improving the continuity and efficiency of production testing.

[0003] In the existing technology, the workpiece conveying of bearing bridge inspection lines mostly adopts a fixed conveyor belt structure. The workpiece is transferred by the continuous operation of the conveyor belt. In terms of workpiece positioning, fixed blocks or limit rods are usually set on both sides of the conveyor belt. The contact between the blocks and the workpiece is used to limit the lateral displacement of the workpiece in order to maintain the approximate position of the workpiece during the conveying process.

[0004] However, the aforementioned existing technology has a shortcoming: the fixed or manually adjustable limiting structure is difficult to effectively adapt to the size changes of bearing bridge workpieces of different specifications. During high-speed or continuous conveying, the workpiece is very prone to positional deviation due to vibration, inertia or initial placement deviation, resulting in a deviation between the actual posture of the workpiece when it arrives at the inspection station and the preset ideal posture, which in turn affects the accuracy and reliability of subsequent inspection results. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular bearing bridge inspection line, which aims to improve the problem that fixed or manually adjustable limiting structures are difficult to effectively adapt to the size changes of bearing bridge workpieces of different specifications, resulting in a deviation between the actual posture of the workpiece and the preset ideal posture when it arrives at the inspection station, thus affecting the accuracy and reliability of subsequent inspection results.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular bearing bridge inspection line, including a support first, wherein the upper surface of the support first is provided with an inspection and conveying module, a coding module, an airtightness inspection module, a vision inspection module, a rotation test module, an assembly verification module and a control module, and a support second is fixedly connected to the upper surface of the support first, wherein the inner wall of the support second is provided with a correction component;

[0007] The correction assembly includes two limiting plates. The outer wall of the limiting plate is slidably connected to the inside of the second bracket. A sliding plate is fixedly connected to the upper surface of the limiting plate. A slide rail is slidably connected to the inner wall of the sliding plate. The upper surface of the slide rail is fixedly connected to one side of the inner wall of the second bracket.

[0008] Furthermore, the inner wall of the slide plate is symmetrically provided with cylinders in opposite directions, and the output end of the cylinder is fixedly connected to one side of the inner wall of the slide plate opposite to the fixed end of the cylinder.

[0009] Furthermore, a rotating shaft is fixedly connected to the inner wall of the second bracket, a gear is rotatably connected to the outer wall of the rotating shaft, and a rack is fixedly connected to the upper surface of the slide plate, with the gear teeth meshing with the rack teeth.

[0010] Furthermore, a support plate is fixedly connected to one side of the outer wall of the first bracket, a material conveying module is provided above the support plate, a third bracket is fixedly connected to one side of the outer wall of the support plate, and a good product conveying module is provided on the upper surface of the third bracket.

[0011] Furthermore, a motor is fixedly connected to the upper surface of the support plate, and the output end of the motor is fixedly connected to the lower surface of the material conveying module.

[0012] Furthermore, a support rod is fixedly connected to the upper surface of the material distribution and conveying module, and an industrial camera is fixedly connected to one side of the outer wall of the support rod.

[0013] Furthermore, a slide is fixedly connected to one side of the outer wall of the support plate, and a scrap frame is fixedly connected to the outer wall of the slide.

[0014] Furthermore, a fourth bracket is fixedly connected to one side of the outer wall of the first bracket, and a rework conveying module is fixedly connected to the upper surface of the fourth bracket.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the corresponding slide plate is pulled by the cylinder in the opposite direction to slide along the slide rail. The gear meshes with the rack fixed on the upper surface of the slide plate to drive the two limit plates to move closer or further away from each other in sync. This realizes the position correction of bearing bridge workpieces of different specifications, ensures the workpiece has a precise posture during the conveying process, avoids the impact of positional deviation on the subsequent detection accuracy, and thus improves the practicality of the device.

[0017] 2. In this utility model, the rotating material sorting and conveying module driven by a motor, combined with the intelligent recognition of an industrial camera, replaces manual sorting, greatly improving sorting efficiency and avoiding human error, ensuring accurate sorting results. At the same time, the classification settings of the good product conveying module, the rework conveying module, and the waste product box ensure that workpieces with different test results flow accurately to the corresponding areas, avoiding material mixing, facilitating subsequent good product circulation, waste product processing, and rework operations, improving the standardization of the production process and overall efficiency, thereby enhancing the practicality of the device.

The outer wall of the limiting plate 24 is slidably connected to the inside of bracket 2 (4). A sliding plate 22 is fixedly connected to the upper surface of the limiting plate 24. A slide rail 21 is slidably connected to the inner wall of the sliding plate 22.

The gear 26 is rotatably connected to the outer wall of the rotating shaft 25. A rack 27 is fixedly connected to the upper surface of the sliding plate 22. The tooth ends of the gear 26 mesh with the tooth ends of the rack 27, and the rack 27 cooperates with the gear 26.To eliminate potential stroke errors caused by cylinder 23 directly pushing slide plate 22, the two slide plates 22 and the limiting plate 24 are forced to move closer or further apart synchronously and at the same distance, ensuring correction accuracy.

[0027] Reference Figure 1 , Figure 2 and Figure 5 A support plate 10 is fixedly connected to one side of the outer wall of bracket 1. A material conveying module 11 is installed above the support plate 10. A bracket 3 12 is fixedly connected to one side of the outer wall of the support plate 10. A good product conveying module 13 is installed on the upper surface of bracket 3 12. The good product conveying module 13 is used to transport qualified workpieces to subsequent production processes, realizing the orderly transfer of qualified products and ensuring the continuity of the production process. A motor 16 is fixedly connected to the upper surface of the support plate 10. The motor 16 works with the material conveying module 11 to rotate. According to the judgment result of the industrial camera 18, the motor 16 drives the material conveying module 11 to turn to the good product, waste product or rework product channel to realize fully automatic sorting. The output end of the motor 16 is fixedly connected to the material conveying module. On the lower surface of module 11, a support rod 17 is fixedly connected to the upper surface of the material conveying module 11. An industrial camera 18 is fixedly connected to one side of the outer wall of the support rod 17. The industrial camera 18 is used to identify the workpiece identification code and verify the test results. A slide table 19 is fixedly connected to one side of the outer wall of the support plate 10. The slide table 19 is used to guide the unqualified waste products into the waste frame 20, providing guidance for the conveying of waste products. The waste frame 20 is fixedly connected to the outer wall of the slide table 19. A bracket 14 is fixedly connected to one side of the outer wall of bracket 1. A rework conveying module 15 is fixedly connected to the upper surface of bracket 14. The rework conveying module 15 is used to convey the defective products that need to be reworked to the rework processing area, realizing the centralized transfer of defective products and facilitating subsequent rework processing.

[0028] Working principle: When inspecting the bearing bridge, the bearing bridge workpiece is first placed on the inspection conveying module 2. The inspection conveying module 2 is started, which drives the workpiece to move along the conveying direction to the subsequent inspection station. When the workpiece is conveyed to the bracket 4, the cylinder 23 in the opposite direction pulls the corresponding slide plate 22 to slide along the slide rail 21. The gear 26 meshes with the rack 27 fixed on the upper surface of the slide plate 22, which drives the two limit plates 24 to move closer or further away from each other in sync. This realizes the position correction of bearing bridge workpieces of different specifications, ensures the workpiece has a precise posture during the conveying process, and avoids the impact of position deviation on the subsequent inspection accuracy.

[0029] After correction, the workpiece passes through each detection module in sequence. First, it reaches the inkjet printing module 3, which prints and numbers the workpiece surface to provide a basis for subsequent quality traceability. Then, the workpiece is transported to the airtightness detection module 5, where the sealing performance of the bearing bridge is tested by the airtightness detection equipment to determine whether there are any leakage defects. Next, it enters the vision inspection module 6, which uses visual recognition technology to conduct a comprehensive inspection of the workpiece's appearance, size, assembly status, etc. Then, it reaches the rotation test module 7, which tests the rotation performance of the bearing bridge to verify its smoothness and stability during rotation. Finally, it enters the assembly verification module 8 to check whether the assembly of each component of the bearing bridge meets the design requirements. In the entire detection process, the control module 9, as the core control unit, coordinates the operation sequence and action logic of each module to achieve fully automated detection.

[0030] After inspection, the workpiece is conveyed to the sorting and conveying module 11. At this time, the industrial camera 18 identifies the workpiece identification code to verify the information and confirm the final inspection result. If the workpiece is a qualified product, it is conveyed to the good product conveying module 13 supported by the bracket 12 through the sorting and conveying module 11 to enter the subsequent production process. If the workpiece is a defective product, the motor 16 is started to drive the sorting and conveying module 11 to rotate to the direction of the slide table 19 and push the defective product into the fixed defective product frame 20 on the slide table 19 for centralized collection. If the workpiece is a defective product that needs to be reworked, the sorting and conveying module 11 rotates to the direction of the rework conveying module 15 to enter the rework process.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
