Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ultrasonic testing technology, specifically relating to a liquid level rapid lifting mechanism. Background Technology
[0002] Fully automatic ultrasonic testing equipment is a highly efficient non-destructive testing tool widely used in the industrial field. It utilizes the propagation characteristics of ultrasonic waves to detect and locate internal defects in materials. When ultrasonic waves encounter different media interfaces, they will undergo reflection, refraction, or transmission. The equipment analyzes the internal structure and defects of the material by transmitting and receiving the reflected signals.
[0003] When handling the workpiece in a fully automatic ultrasonic testing equipment, it is desirable for the workpiece to be exposed to the testing medium (oil or water) to prevent the grippers from dripping oil or water onto other parts of the equipment. However, for some types of workpieces undergoing ultrasonic testing, the distance between the probe and the workpiece must be only about 0.5mm, and there are parallelism and positional tolerance requirements between the workpiece and the probe during testing to ensure accurate test results. If the workpiece is brought into the liquid by raising and lowering the workpiece fixture, the workpiece is prone to displacement during the raising and lowering process, resulting in repeated positioning accuracy problems, which in turn affects the testing effect. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a liquid level rapid lifting mechanism.
[0005] The technical solution adopted to solve the above technical problems is: a liquid level rapid lifting mechanism, including a frame, a main oil tank fixedly connected to one side of the top of the frame, an auxiliary oil tank slidably connected to the side of the top of the frame away from the main oil tank, a U-shaped pipe fixedly connected to the bottom of the auxiliary oil tank and the main oil tank, the auxiliary oil tank and the main oil tank being interconnected through the U-shaped pipe, and a lifting component installed at the bottom of the auxiliary oil tank.
[0006] Furthermore, the lifting assembly includes a telescopic cylinder, the bottom end of which is fixedly connected to the frame, and the top telescopic end of which is fixedly connected to a mounting plate, which is fixedly connected to the auxiliary oil tank.
[0007] The above technical solution enables rapid lifting and lowering of the auxiliary oil tank, thereby quickly adjusting the liquid level when the workpiece enters the testing medium, ensuring the workpiece remains stable during the testing process and improving testing accuracy. In addition, the use of telescopic cylinders can reduce the complexity of the mechanical structure, improve the system's response speed and positioning accuracy, and make the entire testing process more efficient and accurate.
[0008] Furthermore, linear bearing guide shafts are fixedly connected to the four corners of the bottom of the mounting plate, and the middle of several linear bearing guide shafts are slidably connected to the frame.
[0009] Through the above technical solution, the design of the linear bearing guide shaft enables the auxiliary oil tank to move along a predetermined straight path during lifting and lowering, ensuring that the auxiliary oil tank remains stable during the lifting and lowering process and avoiding liquid surface fluctuations caused by shaking or tilting, thereby ensuring the stability and repeatability of the testing process.
[0010] Furthermore, a sliding guide rail is fixedly connected to the bottom inner side of the main oil tank, and a detection slide is slidably connected to the top of the sliding guide rail, with a detection workpiece placed on the top surface of the detection slide.
[0011] Through the above technical solution, the inspection slide can move freely along the sliding guide rail in the main oil tank, thereby realizing precise position adjustment of the workpiece. This not only improves the flexibility of inspection, but also ensures the stability and accuracy of the workpiece during the inspection process. In addition, the combined use of the sliding guide rail and the inspection slide can reduce errors caused by mechanical vibration or improper operation, further improving the performance of the entire inspection system.
[0012] Furthermore, an electric guide rail is fixedly connected to the top of the frame. The electric guide rail is located on one side of the top opening of the main oil tank. A fixed slide is slidably connected to the surface of the electric guide rail. An ultrasonic generator is fixedly connected to the side of the fixed slide near the main oil tank. The bottom end of the ultrasonic generator extends into the interior of the main oil tank, and a probe is provided at the bottom end of the ultrasonic generator.
[0013] Through the above technical solution, the use of electric guide rails allows the ultrasonic generator to move along the guide rails on the top of the main oil tank, thereby enabling rapid detection of ultrasonic waves in different directions, which greatly improves detection efficiency and detection quality.
[0014] Furthermore, lifting support pads are installed at the four corners of the bottom of the frame, and several movable pulleys are fixedly connected to both sides of the bottom of the frame.
[0015] Through the above technical solutions, the stability of the frame is significantly improved, while facilitating quick adjustment and movement of the entire liquid level lifting mechanism in different working environments. The lifting support pad can adapt to different ground flatness, ensuring the stability and safety of the mechanism during operation. The installation of movable pulleys greatly reduces the movement resistance of the mechanism on the ground, allowing operators to easily move the mechanism to the designated position and improve work efficiency.
[0016] The beneficial effects of this utility model are as follows:
[0017] 1. This utility model uses a lifting assembly consisting of a cylinder, four sets of linear bearing guide shafts, and a secondary oil tank mounting plate. The main and secondary oil tanks are connected by a U-shaped hose. When the secondary oil tank rises, oil flows to the main oil tank, raising the oil level in the main oil tank. When the secondary oil tank falls, oil flows back to the secondary oil tank, lowering the oil level in the main oil tank and exposing the workpiece to the oil surface. Compared with traditional workpiece lifting mechanisms, since the workpiece is stationary, there is no problem with repeated positioning accuracy, thus ensuring the positional accuracy between the probe and the workpiece.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] like Figures 1 to 4 As shown, a liquid level rapid lifting mechanism in this embodiment includes a frame 1. A main oil tank 3 is fixedly connected to one side of the top of the frame 1. An auxiliary oil tank 2 is slidably connected to the side of the top of the frame 1 away from the main oil tank 3. A U-shaped pipe 6 is fixedly connected to the bottom of the auxiliary oil tank 2 and the main oil tank 3. The auxiliary oil tank 2 and the main oil tank 3 are interconnected through the U-shaped pipe 6. A lifting component is installed at the bottom of the auxiliary oil tank 2. The lifting of the auxiliary oil tank 2 determines whether the liquid level in the main oil tank 3 rises or the liquid level in the auxiliary oil tank 2 falls.
[0025] The lifting assembly includes a telescopic cylinder 4, the bottom of which is fixedly connected to the frame 1. A mounting plate 9 is fixedly connected to the top telescopic end of the telescopic cylinder 4. The mounting plate 9 is fixedly connected to the auxiliary oil tank 2, which enables the rapid lifting and lowering of the auxiliary oil tank 2 and ensures that the workpiece 10 remains stable during the inspection process. Linear bearing guide shafts 5 are fixedly connected to the four corners of the bottom of the mounting plate 9. The middle of several linear bearing guide shafts 5 is slidably connected to the frame 1 through the shaft, so that the auxiliary oil tank 2 can move along a predetermined straight path during lifting and lowering, which can ensure that the auxiliary oil tank 2 remains stable during the lifting and lowering process.
[0026] A sliding guide rail 12 is fixedly connected to the bottom inner side of the main oil tank 3. A detection slide 13 is slidably connected to the top of the sliding guide rail 12. The detection workpiece 10 is placed on the top surface of the detection slide 13. The detection slide 13 can move freely along the sliding guide rail 12 inside the main oil tank 3, thereby realizing precise position adjustment of the detection workpiece 10 and improving the flexibility of detection.
[0027] An electric guide rail 11 is fixedly connected to the top of the frame 1. The electric guide rail 11 is located on one side of the top opening of the main oil tank 3. A fixed slide table 14 is slidably connected to the surface of the electric guide rail 11. An ultrasonic generator 16 is fixedly connected to the side of the fixed slide table 14 near the main oil tank 3. The bottom end of the ultrasonic generator 16 extends into the interior of the main oil tank 3. A probe 15 is provided at the bottom end of the ultrasonic generator 16, which allows the ultrasonic generator 16 to move along the electric guide rail 11, thereby realizing rapid detection of ultrasonic waves in different directions, greatly improving detection efficiency and detection quality.
[0028] Lifting support pads 7 are installed at the four corners of the bottom of the frame 1. Several movable pulleys 8 are fixedly connected to both sides of the bottom of the frame 1. The lifting support pads 7 can adapt to the flatness of different ground surfaces, ensuring the stability and safety of the mechanism during operation. The movable pulleys 8 greatly reduce the movement resistance of the mechanism on the ground, allowing operators to easily move the mechanism to the designated position and improve work efficiency.
[0029] The working principle of this embodiment is as follows:
[0030] The operator easily moves the frame 1 to the designated position using the movable pulley 8 and fixes it in the required position using the lifting support pad 7. When ultrasonic testing is required, the operator places the workpiece 10 on the testing slide 13. By moving the testing slide 13 on the sliding guide rail 12, the position of the workpiece 10 is adjusted to facilitate ultrasonic testing. Subsequently, the auxiliary oil tank 2 is lifted by the telescopic cylinder 4, and the testing medium is poured into the auxiliary oil tank 2. Then, the telescopic cylinder 4 drives the auxiliary oil tank 2 on the mounting plate 9 to sink. During this process, the design of the linear bearing guide shaft 5 allows the auxiliary oil tank 2 to move along a predetermined straight path during lifting and lowering, ensuring that the auxiliary oil tank 2 remains stable during the lifting and lowering process. Due to the main oil tank 3 and the auxiliary oil tank 2... The two are connected by a U-shaped tube 6. When the auxiliary oil tank 2 rises, the oil flows to the main oil tank 3, and the liquid level in the main oil tank 3 rises. The workpiece is slowly immersed in the detection medium. At this time, the electric guide rail 11 drives the fixed slide 14 to move, so that the ultrasonic generator 16 can move along the guide rail on the top of the main oil tank 3, thereby realizing the rapid detection of ultrasonic waves in different directions, which greatly improves the detection efficiency and detection quality. After the detection is completed, when the auxiliary oil tank 2 falls, the oil flows back to the auxiliary oil tank 2, the liquid level in the main oil tank 3 drops, and the workpiece is exposed. Therefore, this mechanism can make the workpiece submerged or exposed in the liquid while the workpiece is stationary. Since the workpiece is stationary, there is no problem of repeated positioning accuracy, which ensures the positional accuracy between the probe 15 and the workpiece, improving the detection efficiency and detection quality.
