Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically a mechanical parts processing defect detection device. Background Technology

[0002] Mechanical parts processing refers to the production process of transforming raw materials (such as metals, plastics, ceramics, etc.) into mechanical parts that meet specific design requirements through a series of technological methods and equipment.

[0003] A prior patent (publication number: CN222063092U) discloses a defect detection device for machined parts, comprising a belt conveyor and a base plate. The belt conveyor is mounted on the upper end of the base plate. A support connecting block is provided at the lower end of the base plate, and a support leg is provided at the lower end of the support connecting block. A detection bracket is provided at the upper end of the belt conveyor, and a detection body is provided at the top of the inner part of the detection bracket. A defect pusher is provided in front of the detection bracket on the belt conveyor, and a rolling positioning mechanism is provided on the right side of the detection bracket on the belt conveyor. The belt conveyor, the detection body, the rolling positioning mechanism, and the defect pusher are electrically connected to an external controller. The defect detection device for machined parts disclosed in this utility model has the technical effect of rolling positioning, thereby accurately determining the conveying position of the machined parts.

[0004] The aforementioned device has the technical effect of rolling positioning, which can accurately determine the conveying position of mechanical parts. However, in actual use, because the bottom end of the part is in contact with the conveyor, the vision inspection device cannot detect the side of the part in contact with the conveyor belt surface, which leads to insufficient accuracy in the inspection of the part. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mechanical parts machining defect detection device, which has advantages such as improving the accuracy of parts inspection and solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mechanical parts processing defect detection device, comprising a body and a frame, wherein two vertically sliding irregularly shaped supports are arranged inside the frame, and a cylinder is installed on the upper end of each of the two irregularly shaped supports opposite to each other, and a rotating rod is rotatably connected to the output end of each of the two cylinders, and a rubber clamp for clamping parts is fixedly connected to one end of each of the two rotating rods along its axial direction; Each of the rotating rods is fitted with a gear on its outside. The gear and the rotating rod can slide relative to each other in the axial direction, but are fixed relative to each other in the circumferential direction. An annular frame is provided above each of the irregular brackets. The inner wall of each annular frame is fixedly connected with teeth that are evenly distributed along its length direction. The gears are meshed with the corresponding teeth. A second cylinder is fixedly connected to the bottom end of each of the irregular brackets. The output ends of the two second cylinders are fixedly connected to the bottom end of the corresponding annular frame.

[0007] Furthermore, each gear has a groove on its inner wall, and the outer surface of each rotating rod is raised along its axial direction and is slidably connected to the corresponding groove. Each gear has locating rings at both ends along its axial direction, and the two locating rings are clamped on both sides of the annular frame and slide in engagement with it.

[0008] The above design, with its raised surface, allows the gear to slide smoothly on the rotating rod while maintaining a stable relative position during meshing, preventing the gear from falling off or shifting. This ensures the stability and accuracy of the rotating rod's rotation, thereby guaranteeing the smooth operation of the part's flipping motion. The limiting ring further restricts the gear's movement, ensuring it remains stable within the annular frame and preventing positional deviation.

[0009] Furthermore, an electric push rod is installed on the upper surface of the machine body, and the output end of each electric push rod is fixedly connected to the bottom end of the corresponding irregular bracket.

[0010] Through the above solution, the electric push rod provides precise power control for the vertical sliding of the irregular bracket. The height of the irregular bracket can be flexibly adjusted according to the inspection requirements of different parts, thereby changing the inspection position of the parts and enabling the inspection device to adapt to the inspection of more types and sizes of parts.

[0011] Furthermore, a limiting rod is fixedly connected to the upper end of each of the annular frames, and each limiting rod is slidably inserted into the corresponding frame.

[0012] Through the above scheme, the setting of the limit rod plays a guiding and limiting role in the lifting and lowering movement of the ring frame, ensuring that the ring frame always maintains vertical movement during the lifting and lowering process, without deviation or shaking, ensuring accurate meshing of gears and teeth, and improving transmission efficiency and stability.

[0013] Furthermore, the inner wall of the machine body is rotatably connected to two transmission rollers, one end of which is fixedly connected to the output end of an external motor, and a flexible conveyor belt is connected between the two transmission rollers.

[0014] Through the above solution, the flexible conveyor belt can transport parts smoothly and continuously, realize the automated transfer of parts, improve the automation level of the inspection process and production efficiency. At the same time, the flexible conveyor belt has a certain degree of buffering and adaptability, which can reduce the collision and damage of parts during the transportation process.

[0015] Furthermore, two fixing rods are fixedly connected to the upper surface of the machine body, and the upper ends of the two fixing rods are fixed with a correction plate by clamping bolts.

[0016] Through the above scheme, the correction plate can correct the position of the parts during the conveying process, ensuring that the parts are always in the correct detection position, avoiding inaccurate detection or failure to detect due to part position deviation. The correction plate is fixed by clamping bolts, and the position of the correction plate can be easily adjusted according to the size and shape of different parts.

[0017] Furthermore, an industrial inspection camera and a supplementary lighting module are installed on the inner top wall of the frame, with the industrial inspection camera located at the center line of the supplementary lighting module.

[0018] Through the above solution, the industrial inspection camera can quickly and accurately capture image information of parts, providing data support for defect detection. The supplementary lighting module provides sufficient and uniform light for inspection, ensuring that clear and high-quality images can be obtained under different environmental conditions.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: This mechanical parts processing defect detection device, through the cooperation of a cylinder, a rotating rod, and rubber clamps, can clamp parts of different volumes. After clamping the parts, the vertical lifting function of the annular frame allows gears on its inner side to mesh with the teeth on the rotating rod. Under the interaction of the gears and teeth, the rotating rod begins to rotate smoothly, thereby driving the clamped parts to rotate synchronously. This allows the industrial inspection camera to comprehensively photograph and inspect the parts from multiple different angles, effectively avoiding the problem of missed detections caused by a single inspection perspective. Finally, the height of the irregular frame can be flexibly adjusted according to actual needs. This adjustability allows the entire detection device to adapt to the flipping inspection of parts of different volumes, further expanding the applicability and practicality of the detection device.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figures 1-5 This embodiment of a mechanical parts processing defect detection device includes a body 1 and a frame 2. The frame 2 has two vertically sliding irregularly shaped supports 3. A cylinder 4 is fixedly installed on the upper end of each of the two irregularly shaped supports 3 and on the side opposite to each other. The output end of each cylinder 4 is rotatably connected to a rotating rod 5. One end of each rotating rod 5 is fixedly connected along its axial direction to a rubber clamping block 6 for clamping parts. By setting the cylinder 4, rotating rod 5 and rubber clamping block 6 to work together, parts of different volumes can be clamped.

[0024] Gears 7 are slidably sleeved on the outer circumference of each rotating rod 5. An annular frame 8 is provided above each irregular bracket 3. Teeth 9 are fixedly connected to the inner wall of each annular frame 8 along its length and at equal intervals. Gears 7 mesh with corresponding teeth 9. Cylinder 2 10 is fixedly connected to the bottom end of each irregular bracket 3. The output ends of two cylinders 2 10 are fixedly connected to the bottom end of the corresponding annular frame 8. The cylinders 2 10 drive the annular frame 8 to rise and fall, so that during the meshing of gears 7 and teeth 9, the rotating rod 5 is driven to rotate, so that the clamped part can be flipped, and multiple sides of the part can be detected.

[0025] Each gear 7 has a groove 11 on its inner wall. The outer surfaces of the two rotating rods 5 are raised along their axial direction and are slidably connected to the corresponding grooves 11. The raised surfaces of the rotating rods 5 allow the gear 7 to slide smoothly on the rotating rods 5 and ensure a stable relative position with the rotating rods 5 during meshing transmission, preventing the gear 7 from falling off or shifting. This ensures the stability and accuracy of the rotation of the rotating rods 5, thereby ensuring the smooth operation of the part flipping action. An electric push rod 12 is installed on the upper surface of the machine body 1. The output end of each electric push rod 12 is fixedly connected to the bottom end of the corresponding irregular bracket 3. The electric push rod 12 provides precise power control for the vertical sliding of the irregular bracket 3. The height of the irregular bracket 3 can be flexibly adjusted according to the detection requirements of different parts, thereby changing the detection position of the parts and enabling the detection device to adapt to the detection of more types and sizes of parts.

[0026] Each annular frame 8 is fixedly connected to a limiting rod 13 at its upper end. Each limiting rod 13 is slidably inserted into the corresponding frame 2. The limiting rod 13 guides and limits the lifting and lowering movement of the annular frame 8, ensuring that the annular frame 8 always maintains vertical movement during the lifting and lowering process, without deviation or shaking. This ensures accurate meshing of the gear 7 and the teeth 9, improving transmission efficiency and stability. Two transmission rollers 14 are rotatably connected to the inner wall of the machine body 1. One end of one of the transmission rollers 14 is fixedly connected to the output end of an external motor. A flexible conveyor belt 15 is connected between the two transmission rollers 14. The flexible conveyor belt 15 can smoothly and continuously transport parts, realizing automated transmission of parts, improving the automation level of the inspection process and production efficiency. At the same time, the flexible conveyor belt 15 has a certain degree of buffering and adaptability, which can reduce the collision and damage of parts during the transportation process.

[0027] Two fixing rods 16 are fixedly connected to the upper surface of the machine body 1. The upper ends of the two fixing rods 16 are fixed with correction plates 17 by clamping bolts. The correction plates 17 can correct the position of the parts during the conveying process, ensuring that the parts are always in the correct detection position, avoiding inaccurate detection or failure to detect due to part position deviation. The clamping bolts make it easy to adjust the position of the correction plates 17 according to the size and shape of different parts. An industrial inspection camera 18 and a supplementary lighting module 19 are installed on the inner top wall of the frame 2. The industrial inspection camera 18 is located at the center line of the supplementary lighting module 19. The industrial inspection camera 18 can quickly and accurately capture the image information of the parts, providing data support for defect detection. The supplementary lighting module 19 provides sufficient and uniform light for detection, ensuring that clear and high-quality images can be obtained under different environmental conditions.

[0028] Each gear 7 forms a limiting ring 20 at both ends along its axial direction. The two limiting rings 20 are clamped on both sides of the annular frame 8 and slide with it. By setting the limiting rings 20, the gear 7 can be limited, so that the gear 7 can maintain stable movement within the annular frame 8 and prevent the position of the gear 7 from shifting.

[0029] It should be noted that industrial inspection cameras are the core component of machine vision systems. They can convert optical images into digital signals, providing basic data for subsequent image processing and analysis. Their working principle mainly involves optical imaging, image sensing, signal processing and transmission.

[0030] The working principle of the above embodiment is as follows: First, when the part is inspected, an external motor drives one of the transmission rollers 14 to rotate. The flexible conveyor belt 15 is driven by the cooperation of the two transmission rollers 14 to transport the part. When the part passes the two correction plates 17, the part will contact the correction plates 17 and be centered on the flexible conveyor belt 15.

[0031] When the part is located below the industrial inspection camera 18, two cylinders 4 push two rotating rods 5 to slide within the gear 7, causing two rubber clamps 6 to move towards each other and clamp the part. Subsequently, the electric push rod 12 pushes the irregular bracket 3 to slide upward within the frame 2, causing the part to rise vertically on the flexible conveyor belt 15. Then, cylinder 10 drives the annular frame 8 to descend, causing the teeth 9 to mesh with the gear 7, thereby driving the gear 7 to rotate. During the rotation of the gear 7, the contact between the sliding groove 11 and the protruding part of the rotating rod 5 can drive the rotating rod 5 to rotate. During the rotation of the rotating rod 5, the part can be flipped, allowing the industrial inspection camera 18 to inspect multiple sides of the part, thereby improving the accuracy of the part inspection.
