Description

Technical Field

[0001] This utility model belongs to the field of capillary tube detection technology, specifically an online detection device for capillary tube surface defects. Background Technology

[0002] As a key basic component in the industrial field (such as metal tubing for oil and gas transportation, polymer tubing for medical consumables, and synthetic fiber tubing for textile equipment), the surface quality of capillary tubes directly determines the safety, reliability, and service life of end products. With the upgrading of capillary tube quality requirements in downstream industries (such as petrochemicals, medical devices, and high-end manufacturing), and the transformation of industrial production towards "automation, intelligence, and continuous operation," the demand for online inspection devices has emerged.

[0003] Meanwhile, a square tube surface defect detection device with application number CN202022424766.6 includes a transmission device and an illumination device located on one side of the transmission device. The illumination device includes a support and a laser lamp mounted on the support. A square tube slides on the transmission device, and the laser light from the laser lamp obliquely shines on the upper surface of the square tube. A light sensing device is installed on the other side of the transmission device. The light sensing device includes a light sensor and a display. The transmission device includes an outer frame, a conveyor belt located inside the outer frame, a transmission roller, and a servo motor mounted on one of the transmission rollers. A base is installed at the bottom of the servo motor, and fixed bearings are provided at both ends of the transmission rollers. The fixed bearings are mounted on the outer frame.

[0004] However, the following problems were found in the implementation of the relevant technology: it only uses the straight-line transport of pipe fittings and fixed camera to take pictures, which cannot cover the area around the pipe fittings or the entire surface area, and it is easy to miss the dents and cracks on the side and below; resulting in a high rate of missed detection of pipe fittings. At the same time, under a single view, reflective spots and stains on the surface of the capillary tube are easily misjudged as "pockmarks", and fine cracks are easily missed due to the blurry imaging, resulting in a high rate of misjudgment. Manual secondary verification is required, which increases the detection cost.

[0005] Therefore, we propose an online detection device for capillary surface defects. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides an online detection device for capillary surface defects. It has the advantages of being able to drive the capillary to rotate and, in conjunction with a movable appearance inspection instrument, to achieve all-round scanning of the capillary surface. At the same time, it can quickly and easily install and remove the capillary, reducing positioning time.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an online detection device for capillary surface defects, comprising a worktable, a mounting base fixedly connected to the upper surface of the worktable, a motor fixedly connected to the outer surface of the mounting base, a rotating rod fixedly connected to the output end of the motor, a support rod fixedly connected to the outer surface of the rotating rod, three sets of fixing mechanisms provided on the support rod, each fixing mechanism comprising a base plate, a spring fixedly connected to the outer surface of the base plate, a top block fixedly connected to the other end of the spring, a support frame fixedly connected to the upper surface of the worktable, a slide rail fixedly connected to the top surface of the support frame, a slider slidably connected to the slide rail, an appearance inspection instrument mounted on the lower surface of the slider, a hydraulic cylinder mounted on the support frame, a telescopic rod fixedly connected to the output end of the hydraulic cylinder, and the other end of the telescopic rod fixedly connected to the slider.

[0008] Preferably, a rubber plate is fixedly connected to the outer surface of the top block, and the front side of the top block is inclined.

[0009] Preferably, one set of the fixing mechanism includes four top blocks, which are evenly spaced around the outside of the support rod.

[0010] Preferably, the support rod is provided with a groove, and the base plate is located in the groove.

[0011] Preferably, limit plates are fixedly connected to both ends of the slide rail, and the limit plates are fixedly connected to the support frame to form a clear sliding stroke boundary, preventing the slider from exceeding the set position and improving safety.

[0012] Preferably, a capillary tube body is placed on the support rod, and the capillary tube body is mounted on the support rod via a top block.

[0013] Preferably, a baffle is fixedly connected to one end of the support rod. The baffle provides the simplest mechanical limit to prevent the capillary body from entering the wrong position during the arrangement and assembly process. The fixed position of the baffle allows for quick and accurate positioning during each assembly. During the inspection process, the baffle acts as the first line of protection to reduce the risk of impact between structural components.

[0014] Preferably, an elastic column is fixedly connected to the outer surface of the base plate, and the other end of the elastic column is fixedly connected to the top block to reduce swaying and nonlinear motion.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the cooperation of a motor, rotating rod, support rod, base plate, spring and top block, can drive the capillary tube to rotate, realize all-round scanning of the capillary tube surface, reduce blind spots, increase probe coverage area and defect detection probability. At the same time, the uniform rotation speed and angle control can stably and repeatedly scan the path, reduce the variables caused by manual movement, and can quickly and easily install and remove the capillary tube, reduce positioning time and improve detection efficiency.

[0016] 2. This utility model uses the cooperation of hydraulic cylinder, telescopic rod, slide rail and slider to drive the appearance inspection instrument to slide, and perform inspection from multiple positions and different angles. It can cover the entire surface of the capillary and key boundaries, reduce blind spots, and reduce detection errors caused by surface micro-texture, reflection and other factors through multi-view observation, thereby improving the accuracy of defect identification.

[0021] Specifically, a rubber plate is fixedly connected to the outer surface of the top block 8 to increase friction and prevent the capillary body 15 from sliding. The front side of the top block 8 is inclined.

[0022] Furthermore, a set of fixing mechanisms includes four top blocks 8, which are evenly spaced around the outside of the support rod 5.

[0023] Furthermore, the support rod 5 is provided with a groove 13, and the base plate 6 is located in the groove 13.

[0024] It is worth noting that limit plates are fixedly connected to both ends of the slide rail 10. The limit plates are fixedly connected to the support frame 9 to limit the sliding range of the slider 11 and improve safety.

[0025] It is worth noting that a capillary body 15 is placed on the support rod 5, and the capillary body 15 is installed on the support rod 5 through the top block 8.

[0026] It is worth mentioning that a baffle 14 is fixedly connected to one end of the support rod 5 to limit the position of the capillary body 15.

[0027] It is worth emphasizing that an elastic column 16 is fixedly connected to the outer surface of the base plate 6, and the other end of the elastic column 16 is fixedly connected to the top block 8 to ensure the linear movement of the top block 8 and prevent the spring 7 from tilting.

[0029] Working principle: In use, the capillary tube body 15 is first inserted into the outside of the top block 8, and the capillary tube body 15 presses against the top block 8 from the inclined side and slides on the top block 8. The top block 8 retracts backward by the elastic force of the spring 7, so that the capillary tube body 15 is inserted into the outside of the support rod 5, and the elastic force is applied to the top block 8 by the spring 7, thereby fixing the position of the capillary tube body 15 by the top block 8. Then, the motor 3 on the mounting base 2 drives the rotating rod 4 to rotate, the rotating rod 4 drives the support rod 5 to rotate, thereby driving the capillary tube body 15 to rotate.
