Description

Technical Field

[0001] This utility model belongs to the field of surface treatment equipment technology, specifically relating to a lifting adaptive flexible grinding device for surface treatment. Background Technology

[0002] In the maintenance of ships, bridges, storage tanks, and large steel structures, removing rust and old paint from surfaces is a demanding and crucial task. Common methods include: 1. Manual grinding / scraping: Inefficient, labor-intensive, with harsh working environments, and quality depends heavily on worker experience, making consistency difficult; 2. Rigid automated grinding equipment: Typically uses guide rails or robotic arms to drive grinding discs (such as grinding wheels or sanding discs). While highly automated, it requires extremely high surface flatness. When encountering uneven surfaces, rigid contact leads to inconsistent grinding force; excessive pressure can damage the equipment or the base material, while insufficient pressure results in incomplete cleaning, requiring repeated grinding and reducing efficiency; 3. Simple flexible tools: Some tools attempt to provide pressure using airbags or simple springs, but often lack stable vertical feed and reliable force control, failing to achieve precise constant-force grinding and exhibiting poor adaptability on complex curved surfaces.

[0003] Therefore, there is an urgent need in the field for a device that can provide stable and accurate vertical feed, adapt to the undulations of the workpiece surface, and maintain constant grinding pressure, so as to balance automation efficiency and grinding quality. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a lifting adaptive flexible grinding device for surface treatment to solve the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A lifting adaptive flexible polishing device for surface treatment includes a polishing module, a lifting module for controlling the vertical lifting of the polishing module, and a connecting plate for connecting the polishing module and the lifting module. The polishing module includes a polishing motor, a coupling for power connection to the output end of the polishing motor, a rotating shaft for transmission connection to the coupling, a bearing sleeved on the rotating shaft, a connecting plate fixedly connected to the end of the rotating shaft, a guide rod slidably connected to the connecting plate in a vertical direction, a spring sleeved on the guide rod, and a polishing disc fixedly connected to the end of the guide rod.

[0006] Furthermore, the lifting module includes a base, a vertical plate fixedly connected to the base, a linear guide rail fixedly installed on the vertical plate, a lifting motor fixedly connected to the top of the vertical plate, a drive gear poweredly connected to the output end of the lifting motor, a driven gear meshing with the drive gear, a lead screw fixedly connected to the driven gear, and a slider threadedly connected to the lead screw. The slider is slidably connected to the linear guide rail and fixedly connected to the connecting plate.

[0007] Furthermore, a dust cover is fitted onto the grinding disc.

[0008] Furthermore, the lifting module is covered with a lifting protective housing, which is fixedly connected to the base. The lifting protective housing has a long through groove that corresponds to the stroke of the slider, for connecting the plate to move up and down.

[0009] Furthermore, the grinding motor cover is equipped with a motor protective shell.

[0010] Compared with the prior art, this utility model has the following advantages: 1. This utility model has high adaptability: the flexible structure of the spring can adapt well to the unevenness and curvature changes of the workpiece surface, greatly improving the device's ability to handle complex curved surfaces; 2. This utility model can protect the workpiece and equipment: the flexible contact avoids damage to the precision workpiece caused by rigid impact, and also protects the grinding motor and equipment structure from excessive reaction force. 3. The present invention provides stable grinding quality: constant pressure ensures uniform grinding depth and effect, thus improving the processing quality; 4. This utility model has a high degree of automation integration: the entire device is easy to integrate, achieving a high degree of automation and precise stroke control, and can be widely used in robots to replace manual operations.
