Description
Technical Field
[0001] This utility model relates to the technical field of automotive engine cylinder block cleaning equipment, and in particular to a rotating mechanism sealing door. Background Technology
[0002] In automotive engine block cleaning equipment, rotary cleaning mechanisms are frequently used. In order to avoid the rotation range of the fixed door panel, the existing sealed door is a lifting door panel with a lifting height that is much higher than the height of the fixed door panel. This results in a large space occupation due to the lifting height, the stroke of the lifting cylinder and its shape, which wastes equipment space and increases the floor space of the production line.
[0003] In view of the problems existing in the above-mentioned prior art, it is necessary to research and design a new type of rotating mechanism sealing door to overcome the problems existing in the prior art. Summary of the Invention
[0004] To address the technical problems of existing sealing doors, such as the large cylinder size and stroke due to structural reasons, resulting in wasted equipment space and a large production line footprint, this invention provides a rotating mechanism sealing door. This utility model primarily designs the connecting side of the lifting door panel and the fixed door panel with a structure that is narrower at the top and wider at the bottom. This ensures that the lifting height of the lifting door panel does not need to exceed the height of the fixed door panel, shortening the lifting height of the lifting door panel and the stroke of the telescopic cylinder, thus greatly optimizing the overall structural space.
[0005] The technical means adopted in this utility model are as follows: A rotating mechanism sealing door device is installed in a cleaning chamber to seal the cleaning fluid medium, comprising: a lifting door plate, a lifting door structure, a fixed door plate, a fixed door rotating structure, and a limiting structure; Furthermore, the fixed door panel is connected to the fixed door rotating structure fixedly mounted on the equipment, and the fixed door panel rotates under the drive of the fixed door rotating structure; Furthermore, the lifting door panel is mounted on the equipment wall panel through the lifting door structure, and moves vertically up and down under the drive of the lifting door structure, realizing the opening and closing of the lifting door panel and the fixed door panel; Furthermore, a limit structure is installed between the lifting door panel and the equipment wall panel to detect when the lifting door panel rises and falls into place; Furthermore, the joint surfaces on both sides of the lifting door panel and the fixed door panel are designed to be narrower at the top and wider at the bottom, which allows the lifting door panel to detach from the fixed door panel after rising a short distance.
[0006] Furthermore, the main body of the lifting door panel is a plate-shaped structure, with a door groove that is narrower at the top and wider at the bottom, which is used to fit into the fixed door panel. Furthermore, a sealing door frame is installed inside the door slot.
[0007] Furthermore, the main body of the fixed door panel is a plate-like structure, and its overall processing is a narrow-at-the-top and wide-at-the-bottom structure that matches the door groove structure of the lifting door panel.
[0008] Furthermore, sealing rubber is installed on the top and sides of the fixed door panel to cooperate with the sealing door frame to seal the space between the fixed door panel and the lifting door panel.
[0009] Furthermore, the lifting door structure includes: a cylinder mounting base, a cylinder, a floating joint, and a connecting plate; Furthermore, one end of the cylinder is fixedly mounted on the equipment wall panel via a cylinder mounting base, and the other end is connected to a connecting plate fixedly mounted on the lifting door panel via a floating joint; the extension and retraction of the cylinder drives the lifting door panel to move up and down.
[0010] Furthermore, guide rails are installed on the equipment walls on both sides of the lifting door panel. The lifting door panel is connected to the guide rails to ensure that the lifting door panel moves up and down in a straight line under the guidance of the guide rails.
[0011] Furthermore, the fixed door rotating structure includes: a rotating platform, a rotating mechanism, and a fixed mounting base; Furthermore, the upper end of the rotating platform is vertically fixedly assembled with a door panel via a door panel mounting bracket; Furthermore, the lower end of the rotating platform is connected to a rotating mechanism fixedly mounted on the equipment.
[0012] Furthermore, the limiting structure includes: a detection plate and a proximity switch; Furthermore, the detection plate is installed on the side of the lifting door panel; Furthermore, there are two proximity switches, mounted on the guide rail, located at the initial and final positions of the lifting door panel respectively, and the detection plate detects the final position of the lifting door panel when it rises or falls.
[0013] The working process of this utility model is as follows: The cylinder guide rod retracts, guiding the lifting door panel and sealing door frame upwards via the guide rail. Once the lifting door panel is in position, the proximity switch detects the detection plate of the lifting door panel and sends a signal. The fixed door panel rotates under the drive of the rotating mechanism. After the fixed door panel rotates 180°, the cylinder guide rod extends, and the lifting door panel and sealing door frame descend together along the guide rail. When the sealing rubber on the fixed door panel is embedded in the sealing door frame, the detection plate also reaches the switch detection point where it has descended to the correct position and sends a signal indicating that it has descended to the correct position. At this point, the cleaning process begins.
[0014] Compared with the prior art, the present invention has the following advantages: 1. The rotating mechanism sealing door provided by this utility model has an angled design on both sides of the lifting door panel and the fixed door panel, which allows the lifting height of the lifting door panel to be no higher than that of the fixed door panel. After a short lifting distance, the rotation of the fixed door panel is not affected. The structure is compact and simple. 2. The rotating mechanism sealing door provided by this utility model features an angled design on both sides of the lifting door panel and the fixed door panel, which greatly saves equipment space and further reduces equipment costs. 3. The rotating mechanism sealing door provided by this utility model has a sealing rubber that is installed in a conformal manner with the fixed door panel, making it easier for the sealing door frame to embed the sealing rubber, resulting in a better and more stable sealing effect; 4. The rotating mechanism sealing door provided by this utility model has a lifting door plate that ensures linear motion through a guide rail. At the same time, the cylinder is connected to the lifting door plate through a floating joint, ensuring a soft connection between the drive mechanism and the motion mechanism and avoiding damage due to equipment vibration.
[0015] In summary, the technical solution of this utility model solves the problems of existing sealing doors, such as large cylinder size and stroke due to structural reasons, resulting in wasted equipment space and large production line footprint. Attached Figure Description
