Description

Technical Field

[0001] This utility model relates to the field of water-cooled plate testing technology, and in particular to a flipping mechanism based on ultrasonic non-destructive testing. Background Technology

[0002] In today's industrial manufacturing sector, product quality control is becoming increasingly stringent. Non-destructive testing (NDT) technology, as a key means of ensuring product quality, has been widely applied and extensively researched. Ultrasonic NDT, due to its advantages such as high precision, non-invasiveness, and good adaptability to various materials, occupies an important position in many industries, including aerospace, automotive manufacturing, and machining, becoming an indispensable tool for detecting internal defects, microstructure characteristics, and material uniformity in products.

[0003] The flipping mechanism produced based on ultrasonic nondestructive testing follows this technological development trend. By introducing advanced mechanical design, automated control and sensor technology, it can achieve rapid and accurate flipping and positioning of the object being tested, providing the ultrasonic probe with a full range of detection angles, greatly improving detection efficiency and quality.

[0004] Traditional ultrasonic nondestructive testing (NDT) processes often rely on manual operation when it comes to workpiece flipping. Inspectors must manually move the workpiece to the designated position, relying on experience and simple tools to determine its orientation. This manual flipping method has several insurmountable drawbacks. Firstly, manual operation is extremely inefficient, especially in large-scale, high-intensity production environments. Frequent handling and flipping easily leads to operator fatigue, significantly extending the testing cycle for a single workpiece. Furthermore, prolonged high-intensity work increases the risk of operational errors, which can then flow into the next production stage, posing a serious threat to product quality. Secondly, manual flipping makes it difficult to guarantee consistency and accuracy in each operation. Different inspectors have inherent differences in their operating techniques and force, resulting in inconsistent workpiece position and orientation before and after flipping. Consequently, the ultrasonic probe struggles to maintain stable testing parameters when in contact with the workpiece surface, leading to significant fluctuations in test data and hindering reliable and stable data support for product quality assessment. Therefore, this paper proposes a flipping mechanism based on ultrasonic NDT to address these issues. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a flipping mechanism based on ultrasonic non-destructive testing, which aims to improve the problem that manual flipping of workpieces in the prior art is prone to operational errors that cause the workpiece to flow into the next process.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1 to 2This utility model provides an embodiment of a flipping mechanism based on ultrasonic non-destructive testing, including a mounting base plate 1. The mounting base plate 1 ensures that the entire mechanism will not shake or shift during operation, guaranteeing the accuracy and reliability of the flipping action, and also facilitates connection and fixation with other external equipment or production lines. A support column 2 is detachably connected to the top of the mounting base plate 1. The support column 2 is composed of three support rods and a panel welded together. A support plate 3 is fixedly connected to the top of the support column 2. The support plate 3 is used to place the workpiece to be flipped, providing a stable support plane for the workpiece and ensuring that the workpiece is in the correct position and posture before flipping.

[0030] A rubber pad 4 is fixedly connected to the top of the support plate 3. The rubber pad 4 is mainly used to buffer the impact force when the workpiece is placed, preventing damage caused by direct rigid contact between the workpiece and the support plate 3. It also provides sufficient friction to ensure the workpiece is fixed in position before flipping, avoiding disruption to subsequent operations due to accidental shaking. The top of the support column 2 is fixedly connected to the bottom of the rubber pad 4, and the support column 2 passes through the support plate 3 to fix the rubber pad 4. A slide cylinder mounting plate 5 is fixedly connected to the top of the mounting base plate 1, providing an installation position and support for the slide cylinder body 6. The side of the support column 2 closest to the slide cylinder body 6 is fixedly connected to the outside of the slide cylinder mounting plate 5, and the outside of the support column 2 is connected to the slide cylinder mounting plate 5.

[0031] refer to Figure 1 The slide cylinder mounting plate 5 is externally fixedly connected to the slide cylinder body 6, which is a common linear drive element. Through the piston movement inside the cylinder, the energy of compressed air is converted into mechanical energy for linear motion. A swing cylinder mounting plate 7 is slidably connected to the top of the slide cylinder mounting plate 5, providing a mounting base for the swing cylinder body 8. The top of the swing cylinder mounting plate 7 is fixedly connected to the swing cylinder body 8, which is the core component for realizing the workpiece flipping action. Through its internal rotating mechanism, it converts the energy of compressed air into mechanical energy for rotational motion.

[0032] A rotating shaft 9 is fixedly connected to the drive end of the swing cylinder body 8. A rotating rod 10 is fixedly connected to the outside of the rotating shaft 9. The rotating shaft 9 connects the swing cylinder body 8 and the rotating rod 10, transmitting the rotational motion of the swing cylinder body 8 to the rotating rod 10. A rear mounting bracket 11 is fixedly connected to the side of the rotating rod 10 away from the rotating shaft 9. The structural design of the rear mounting bracket 11 ensures that the pneumatic finger assembly 13 can accurately clamp the workpiece, and that the workpiece can be stably fixed on it during the flipping process, without displacement or falling off. At the same time, the rear mounting bracket 11 must also be firmly connected to the rotating rod 10 to effectively transmit the flipping force of the rotating rod 10 to the workpiece, ensuring the smooth completion of the flipping action. It is one of the important components for achieving reliable workpiece flipping and clamping.

[0033] The rear mounting bracket 11 is externally fixedly connected to a pad 12, and a pneumatic finger assembly 13 is provided on the outside of the pad 12. The pad 12 is installed on the rear mounting bracket 11, providing a flat mounting surface for the pneumatic finger assembly 13. It also plays a certain role in buffering and protection, preventing the pneumatic finger assembly 13 from damaging the rear mounting bracket 11 when clamping the workpiece. In addition, it can disperse the clamping force of the workpiece to a certain extent, making the workpiece more evenly stressed and avoiding deformation or damage to the workpiece due to excessive local stress.

[0034] A water shield 14 is fixedly connected to the top of the mounting base plate 1. The rear side of the swing cylinder mounting plate 7 is slidably connected to the front side of the water shield 14, and the rear side of the swing cylinder body 8 is slidably connected to the front side of the water shield 14. The water shield 14 is mounted on the mounting base plate 1, located behind the swing cylinder mounting plate 7 and the swing cylinder body 8. Its main function is to shield water splashes, dust, and other impurities, preventing these impurities from entering the swing cylinder body 8, the rotating shaft 9, and other key components, thus affecting their normal operation and service life. A linear guide rail 15 is fixedly connected to the top of the mounting base plate 1, providing precise linear motion guidance for the bearing seat mounting bracket 16.

[0035] A bearing housing mounting bracket 16 is slidably connected to the top of the linear guide rail 15. The bearing housing mounting bracket 16 is used to install a self-aligning bearing 18 with a mounting seat. A wiring fixing bracket 17 is provided at the top of the bearing housing mounting bracket 16. The wiring fixing bracket 17 is used to fix and organize the electrical and air lines related to the flipping mechanism. A self-aligning bearing 18 with a mounting seat is provided at the rear side of the wiring fixing bracket 17. The self-aligning bearing 18 with a mounting seat is connected to the slide cylinder mounting plate 5 via a rotating shaft 9. The front side of the rotating rod 10 is fixedly connected to the outside of the rear self-aligning bearing 18 with a mounting seat. The self-aligning bearing 18 with a mounting seat is a rotation support component of the rotating rod 10, bearing the radial and axial forces of the rotating rod 10 during the flipping process, ensuring that the rotating rod 10 can rotate smoothly and flexibly around its axis. A rear rotation station 19 is provided at the top of the mounting base plate 1. The rear rotation station 19 is used to support the workpiece after flipping.

[0036] refer to Figure 2The pneumatic finger assembly 13 includes a pneumatic finger mounting plate 1301, which is disposed outside the pad 12. Pneumatic grippers 1302 are slidably connected to the outside of the pneumatic finger mounting plate 1301. Rubber pads 1303 are fixedly connected to the adjacent sides of the two pneumatic grippers 1302. The outer surfaces of the pneumatic grippers 1302 and 1303 abut against the top of the support column 2. The pneumatic finger mounting plate 1301 is a flat metal piece used to mount the pneumatic grippers 1302. The plate has corresponding mounting holes and air duct interfaces for connection to an external air source and control system. The pneumatic grippers 1302 generally consist of two relatively moving grippers. Their shape and size are designed according to the shape of the workpiece and clamping requirements. The movement of the grippers is driven by compressed air, enabling rapid and accurate clamping and releasing actions. Rubber pad 1303 is installed on the inner side of pneumatic gripper 1302 and comes into direct contact with the workpiece, serving as a buffer and anti-slip agent.

[0037] Working principle: The robotic arm automatically places the workpiece onto the support plate 3 of the flipping mechanism. Then, the slide cylinder body 6 slides from the zero position towards the desired rotation direction, while the pneumatic finger assembly 13, controlled by an external device, slides the pneumatic gripper 1302 in the center, precisely clamping the workpiece, which has two flat surfaces. During clamping, the pneumatic gripper 1302 drives the rubber pad 1303 to firmly clamp the workpiece.

[0038] Next, the slide cylinder body 6 moves to the rear station 19. After reaching the designated position, the swing cylinder body 8 performs a 180° flip. After the flip is completed, the pneumatic finger assembly 13 releases the gripper and places the workpiece smoothly on the rear station 19.

[0039] Afterwards, the slide cylinder body 6 slides back above the support plate 3, preparing for the next action. At the same time, the swing cylinder body 8 rotates 180° in the opposite direction, returning to its initial state. The slide cylinder body 6 then slides back to the rotating station 19 and finally returns to the zero position, waiting for the robot or a human to perform the next grasping operation.

[0040] This series of actions, through the coordinated work of the robot and the flipping mechanism, achieves automated clamping, flipping, and placement of workpieces, reducing manual intervention and improving production efficiency and stability. At the same time, this flipping mechanism is applicable to various workpieces with two flat sides, without being limited by a specific quantity or type, thus enhancing its adaptability and versatility.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
