Description

Technical Field

[0001] This invention belongs to the field of mechanical technology, specifically an automatic shaking device. Background Technology

[0002] Ultrasonic deburring technology can effectively meet the stringent burr requirements of aerospace and avionics products—namely, no visible burrs under a 10x magnifying glass—and boasts outstanding advantages such as high efficiency, wide applicability, and good processing consistency. However, while removing burrs, this process inevitably causes damage to the surface of the parts.

[0003] During the cavitation process of ultrasonic deburring, the liquid is subjected to alternating compression and expansion by sound waves, causing cavitation bubbles to rapidly form, expand, and collapse, thus creating shock waves and high-speed jets within the liquid. When aluminum alloy parts are subjected to this type of impact over a long period, their surface crystal structure becomes distorted and deformed, leading to chemical instability and ultimately galvanic corrosion. This surface corrosion phenomenon caused by cavitation is called cavitation corrosion.

[0004] Furthermore, aerospace electromechanical components are characterized by their complex structures and diverse shapes. To thoroughly remove all microburrs from the surface of these components, the frequency, current intensity, and processing time of the ultrasonic waves must reach certain thresholds. If the parameters are set too low or the processing time is too short, only burrs near the ultrasonic emission port can be removed, while burrs far from the emission port or inside complex cavities remain difficult to remove. Therefore, in actual production, it is necessary to extend the fixed placement and processing time of the components in the equipment. This leads to an increased cavitation corrosion rate on the surface of the components near the emission port due to excessive and repeated impacts.

[0005] For parts with high appearance requirements, a secondary grinding process must be carried out to eliminate cavitation corrosion marks before subsequent surface treatment. This not only increases the process cost, but also poses a risk of scrapping the parts due to the difficulty of grinding irregular and complex structural parts and the possibility of dimensional deviations after grinding.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figure 1 As shown, an automatic shaking device includes: a top frame 2, a sliding frame 3, a driving device 4, and a placement frame 5. The sliding frame 3 is slidably disposed on the top frame 2. The driving device 4 is mounted on the top frame 2 and connected to the sliding frame 3, and is used to drive the sliding frame 3 to move back and forth. The placement frame 5 is connected to the sliding frame 3 through several connecting pieces 6. The placement frame 5 is capable of shaking.

[0018] The device is placed in the ultrasonic device, the mounting frame 5 needs to be immersed in the solution, and the top frame 2 is fixed to the ultrasonic device.

[0019] The drive unit 4 is installed on the top frame 2. After starting, it outputs power and drives the sliding frame 3 connected to it, so that the sliding frame 3 moves back and forth in a straight line along the preset track of the top frame 2. The placement frame 5 is connected to the sliding frame 3 through several connecting parts 6. The reciprocating linear motion of the sliding frame 3 is transmitted to the placement frame 5 through the connecting parts 6. The linear motion of the sliding frame 3 can drive the placement frame 5 to make a regular swaying motion. The workpiece or material to be processed is placed in the placement frame 5 and moves synchronously with the swaying of the placement frame 5, thereby realizing the uniform swaying processing of the load-bearing object.

[0020] The main purpose of this device is to move the workpiece immersed in the solution to avoid cavitation corrosion.

[0021] The connector 6 in this application is a steel rope.

[0022] Specifically, the driving device 4 is an electric push rod, which is mounted on the top frame 2. The output end of the electric push rod is connected to the sliding frame 3 to drive the sliding motion.

[0023] The electric push rod can precisely control the reciprocating speed and displacement distance of the sliding frame 3 by adjusting the motor speed and stroke parameters, thereby accurately controlling the swaying amplitude and frequency of the placement frame 5.

[0024] Specifically, the placement rack 5 is a hanging basket structure.

[0025] The hanging basket structure often adopts a grid, hollow, or rod splicing design, which has good permeability. In ultrasonic deburring, cleaning and other processes, the liquid medium can quickly penetrate the gaps in the hanging basket and fully contact all surfaces of the workpiece, including complex cavities, corners and other hidden parts, avoiding the problem of burr residue or cleaning dead corners due to the workpiece being blocked by the closed structure.

[0026] Specifically, there are four connectors 6, which are distributed at the four corners of the placement rack 5.

[0027] Four connectors 6 are symmetrically distributed at the four corners of the placement frame 5, which can evenly distribute the power transmitted by the sliding frame 3 to the four stress points of the placement frame 5, avoiding instability caused by single or two-point stress.

[0028] Specifically, the placement rack 5 has railings 51 on both sides for connection, and the bottom of the connector 6 is provided with a quick-release structure 61, which can be detachably connected to the railings 51.

[0029] The quick-release structure 61 allows for rapid assembly and disassembly of the connector 6 and the railing 51 of the placement rack 5 without the need for additional tools such as wrenches and screwdrivers. Operators can complete the replacement or disassembly of the placement rack 5 in a short time. For aviation avionics parts of different specifications and shapes, the appropriate hanging basket placement rack 5 can be quickly switched, effectively shortening the changeover time on the production line and improving the flexibility and adaptability of mass production.

[0030] Specifically, the quick-release structure 61 is a spring retainer.

[0031] The spring buckle relies on its own spring force to quickly lock and unlock. The operator only needs to press the elastic plate of the buckle to quickly insert or release it into or out of the railing 51 of the placement rack 5. No tools are needed throughout the process, and one person can complete the disassembly and assembly of the placement rack 5.

[0032] Specifically, it also includes a stabilizing structure. The lower part of the top frame 2 is connected to the fixed frame 7. The stabilizing structure includes a swing rod 8. The middle part of the swing rod 8 is hinged to the fixed frame 7. The top end of the swing rod 8 is connected to the sliding frame 3 through a first rope 81. The lower end of the swing rod 8 is connected to the placement frame 5 through a second rope 82.

[0033] The hinged swing rod 8 on the fixed frame 7 is equivalent to adding a stable support arm to the placement rack 5. With the constraint of the four corner connectors 6, it can effectively limit the swaying amplitude of the placement rack 5 and avoid the placement rack 5 tilting or tipping over due to uneven workpiece weight distribution or excessive swaying frequency.

[0034] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
