Description

Technical Field

[0001] The invention relates to the technical field of end cap detection, and in particular to a pressure vessel end cap calibration and measurement device. Background Art

[0002] At present, the pressure vessel head is a component that seals the end of the container to isolate the internal and external media. It is used in various fields such as aerospace, military, petrochemical, transportation, food, and medicine. The quality of the head directly affects the safety performance of the pressure vessel, so a comprehensive inspection of the head can effectively prevent potential faults and failure risks.

[0003] The authorization announcement in the prior art is: CN220982865U, and the name is: A pressure vessel head detection device, by adjusting the cooperation between the component and the detection platform, the detection head can accurately abut and detect different positions of the head workpiece, thereby improving the detection accuracy.

[0004] However, although the patent sets an adjustable detection head to detect the surface of the head, when a large number of heads need to be detected, workers are still required to control the detection head to detect the heads, and after the detection is completed, the heads that have been tested need to be manually removed and replaced with untested heads. Overtime, the detection effect will be affected due to overwork of the workers. Furthermore, although there is a laser scanning device in the prior art for detecting the size, surface smoothness, etc. of small and medium-sized heads, the existing equipment can only detect the outer surface or the inner surface of the head during the detection process, and cannot detect both surfaces simultaneously. The object to be detected is often turned over after detecting one side, and more time is needed for detection. In the detection process, multiple groups of different light sources and heads at different angles are not set for detection. In the detection process, the detection effect may be inaccurate due to different head materials or oil stains on the surface, and it cannot adapt to all situations. Therefore, there is an urgent need for an efficient head verification and measurement device that can simultaneously measure the surface smoothness of small and medium-sized heads and check the deviation value of the size of the heads.

[0023] like Figure 1 to Figure 12 As shown, a cleaning shaft 507 is rotatably mounted inside the vertical plate 503, a rotating frame 520 is fixedly sleeved on the outer circumference of one end of the cleaning shaft 507 close to the internal detection component 6, a positioning frame 521 is fixedly connected to the bottom of the rotating frame 520, and a cleaning brush 522 is arranged at the bottom of the positioning frame 521; A cleaning block 523 is installed on one side of the vertical plate 503.

[0027] Embodiment 2: This embodiment provides a pressure vessel head calibration and measurement device, which further includes the following structure based on Embodiment 1: like Figure 1 to Figure 12 As shown, a feed conveyor belt 308 and a feeding conveyor belt 309 are respectively installed on the top of the working bottom plate 7, and a driving motor is installed inside the feed conveyor belt 308 and the feeding conveyor belt 309; The top of the working bottom plate 7 is fixedly connected with a protective cover 2, and a feed port and a feeding port are respectively provided inside the protective cover 2. The feed port is located at the input end of the feed conveyor belt 308, and the feeding port is located at the output end of the feeding conveyor belt 309. A waste port is also provided inside the protective cover 2, and the waste port and the feed port are symmetrically arranged.

If a head that fails the inspection is encountered, the magnetic suction cup will continue to move forward and align with the collection frame 302, and throw it into the collection frame 302. The entire logistics process is automatic, which improves the degree of automation of the entire device and improves the inspection efficiency.

[0028] Embodiment 3: This embodiment provides a pressure vessel head calibration and measurement device, which further includes the following structure based on Embodiment 2: like Figure 1 to Figure 12 As shown, an inner fixing ring 607 is provided on the top of the rotating disk 606, and an annular storage groove 608 is provided inside the inner fixing ring 607, and the width of the storage groove 608 is slightly larger than the thickness of the detected head; A cavity is provided inside the inner fixed ring 607, and an inflation motor is installed inside the inner fixed ring 607. The output end of the inflation motor is connected to the cavity. Since the material of the inner fixed ring 607 is flexible material, air is inflated inside by the inflation motor, so that the two side walls of the storage groove 608 inside the inner fixed ring 607 expand toward the middle, thereby clamping and fixing the internal head, thereby avoiding damage to the surface of the head.

[0029] like Figure 1 to Figure 12 As shown, it also includes a controller, the output ends of the laser scanning head 513 and the internal scanning head 610 are connected to the controller, and the servo cylinder, the movable slide rail, the feed conveyor belt 308, the feeding conveyor belt 309, the inflatable motor, the magnetic suction cup 307, the limit slide rail 602 and the servo motor 505 are all connected to the control point of the controller, and the controller is suitable for controlling the start and stop of the servo cylinder, the movable slide rail, the feed conveyor belt 308, the feeding conveyor belt 309, the inflatable motor, the magnetic suction cup 307, the limit slide rail 602 and the servo motor 505 according to the scanning structure of the laser scanning head 513 and the internal scanning head 610; By setting up structures such as internal detection devices, an internal scanning head 610 is set inside the storage plate 603. During the movement of the head, the fixed rack 2 604 and the annular rack 2 605 are used to drive the head to rotate, so that the entire inner surface can be scanned without switching the scanning head, and the stability is stronger. In addition, by scanning the inner and outer surfaces at the same time, the entire scanning process can be made more comprehensive, thereby ensuring the accuracy of the scanning.

[0030] Working principle: This device realizes the automatic introduction of the end cap by seamlessly connecting the output conveyor belt of the external production device with the internal feed conveyor belt 308. Specifically, the end cap is directly transported by the feed conveyor belt 308 to the bottom of the left magnetic suction cup 307 (the magnetic suction cup 307 is flexible in selection, such as the SGM-S 30 G1 / 8-IG NPN model of the schmalz brand to ensure a stable handling effect). When the end cap reaches the predetermined position, the controller commands the servo cylinder in the vertical moving seat 303 to drive the horizontal moving seat 305 downward. Subsequently, the magnetic suction cup 307 is activated to firmly adsorb the end cap, and the servo cylinder is reset. Then, the moving slide rail in the horizontal moving seat 305 is started to smoothly move the sliding seat 306 to the right to a position aligned with the storage slot 608. The servo cylinder moves again to make the magnetic suction cup 307 carry the end cap down to the storage slot 608. After the placement is completed, the magnetic suction cup 307 is closed and all mechanisms are reset. At this point, the automatic loading process ends; After the head falls into the storage groove 608, the built-in inflation motor of the inner fixed ring 607 is immediately started to inflate the ring, causing the two side walls of the storage groove 608 to shrink inward, thereby achieving lossless and uniform fixation of the head. Subsequently, the controller starts the limiting slide rail 602 to drive the storage plate 603 to move along the slide rail groove 601. During this process, the turntable 606 rotates due to the engagement of the fixed rack 2 604 and the annular rack 2 605, thereby driving the inner fixed ring 607 and the head to rotate. At the same time, the internal scanning head 610 is started to comprehensively scan the inner surface of the rotating head to detect whether there are any defects.

[0031] As the end cap rotates, it is in close contact with the cleaning brush 522 at the bottom of the positioning frame 521. The positioning frame 521 is designed to fit the shape of the end cap, ensuring that the cleaning brush 522 can evenly cover the outer surface of the end cap and effectively remove processing residues such as debris, oil stains, etc. When the end cap continues to move to below the laser scanning head 513, the controller activates the servo motor 505, and drives the active slider 511 to move synchronously by rotating the push screw 506. The laser scanning head 513 (it should be noted that the laser scanning head can be a commercially available laser scanning head that can achieve scanning effects, such as the laser scanning head of model Hexagon produced by Hexagon. This type of laser scanning head is equipped with a visual inspection camera inside, which can simultaneously detect the shape of the end cap at the top) is immediately started to accurately calibrate and measure the outer surface of the end cap. During this process, the light source mounting plate 514 rotates due to the meshing of the annular rack 516 and the fixed rack 517, driving the light source lamp bead 515 to switch, thereby realizing detailed inspection of multiple angles and multiple light sources, and significantly improving the inspection accuracy and efficiency. After the inspection is completed, the storage plate 603 and the active slider 511 reach the end point, and the controller instructs the servo motor 505 and the limit slide rail 602 to run in the opposite direction and reset to the starting position. Then, the servo cylinder moves again, the lateral moving seat 305 moves downward, and the magnetic suction cups 307 on both sides respectively absorb the inspected and uninspected heads. The air charging motor releases the gas in the inner fixing ring 607 to release the head fixation. After the servo cylinder is reset, according to the inspection results, the mobile slide rail sends the qualified heads to the feeding conveyor belt 309, which are collected by the collection frame 302, and the unqualified products are sent to another collection frame 302 to achieve automatic classification; During the movement of the active slider 511, the limit rack 509 drives the limit gear 508 to rotate, driving the positioning frame 521 and the cleaning brush 522 to flip 180° and align them with the compressed gas nozzle on the cleaning block 523. The compressed gas blows the cleaning brush 522 to remove attachments and extend its service life. Thanks to the design of the reset spring 518 (it should be noted that the reset spring is in the initial position when the cleaning brush is facing upward, so the reset spring will drive the brush to reset after the compressed gas stops). The cleaning brush 522 can produce a slight swing during blowing to enhance the cleaning effect. Finally, when the vertical plate 503 is reset, the limit gear 508 rotates 180° again to restore the cleaning brush 522 to the downward state, preparing for the next cleaning task.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
