That is, the lower circular shaft end surface of the grinding wheel 603 is used for horizontally grinding the surface 2 to be processed.

The working principle of the invention is as follows: a positioning reference surface 1 is selected first, and the entire device is fixed to the positioning reference surface 1. Rotating a transverse feeding hand wheel 404 to enable a lead screw I402 of a transverse feeding mechanism 4 to horizontally feed and displace along a horizontal straight line determined by two groups of guide rail sliding blocks I401 under the horizontal straight line guiding action of a guide rail I405; the transverse feeding mechanism 4 horizontally displaces and simultaneously drives the longitudinal feeding mechanism 5 to horizontally linearly feed and displace through the fixing seat I501; a longitudinal feeding hand wheel 504 of the longitudinal feeding mechanism 5 is adjusted in a rotating mode, a lead screw II 506 of the longitudinal feeding mechanism 5 and a fixing seat II 507 fixedly connected with the lead screw II 506 are driven by the lead screw II 506 and the fixing seat II 507 to move up and down along a vertical plane under the vertical linear guiding effect provided by the fixing seat I501, the guide rail sliding block II 503 and the guide rail II 502; meanwhile, the fixed seat II 507 drives the polishing mechanism 6 to wholly vertically lift and displace through a fixed seat III 601 fixedly connected with the fixed seat II 507; the surface 2 to be treated is polished by vertical linear lifting displacement of the polishing wheel 603 of the polishing mechanism 6.

The specific application range of the invention comprises:

1. polishing and repairing local surface flatness of large structural parts such as bridges and trusses which are inconvenient to hoist or process;

2. polishing and repairing the surface flatness of the welding seam after the flat plates are butted;

3. carrying out surface derusting and polishing treatment before welding at the welding position of the surface of the flat plate;

4. and processing the flatness of the plane inside the box body and the surface flatness of the plane butt weld.

From the above description it can be found that: the invention belongs to a plane polishing device capable of moving and replacing positions integrally, and relates to a convenient surface flatness processing tool which comprises: the magnetic type fixing mode has low requirement on the mode state of the surface to be processed of the workpiece, and only needs to be placed stably, safely and reliably and has an operation space; the method has the advantages that the actual working condition on site is utilized, the positioning standard is flexibly selected, and the polishing and repairing treatment of the surface flatness of the workpiece is realized; the installation and carrying are convenient, the use and the operation are convenient, the cost is low, and the treatment efficiency is high; the device can be particularly suitable for being used in complex environments under the condition that a machine tool or other machining modes are inconvenient to use, and can be used as long as the operation space allows.

The manual hand-held polishing operation is adopted, and the polishing device is different from other existing polishing modes in that on one hand, the polishing device is movable, and on the other hand, the polishing device can be applied to local deformation of a workpiece or repair polishing treatment of appearance of a welding seam; when polishing, the measuring reference surface is taken as a positioning reference, then the measuring reference surface is used for positioning, adsorbing and fixing the polishing device, and then the polishing device can be used for polishing the relative position deviation between the surface to be processed and the measuring reference surface by hand operation.

When the longitudinal feeding and the transverse feeding of the invention are both carried out by adopting a linear guide rail and a lead screw and are matched with tools such as the levelness of a grinding surface for use, the grinding precision is high, the labor intensity is low, and the grinding machine tool is equivalent to a fixed grinding machine tool and is equivalent to a movable grinding machine tool.

The invention is mainly used for occasions such as large parts which are inconvenient to process, parts without good processing positioning reference surfaces, temporary plane polishing treatment of construction phenomena or no processing conditions and the like; the device has the advantages of compact structure, convenience and quickness in installation, low use cost, high polishing precision, low labor intensity and wide application range, is suitable for plane polishing treatment in various environments, and is suitable for popularization.

In conclusion, the device has a compact structure, is convenient to install and carry, does not need to rotate the workpiece to be processed again, has no strict requirement on the state of the space of the surface to be processed, and only needs the space to meet the installation and polishing operation of the device; the application of the device for polishing, repairing and processing the surface flatness of the workpiece is realized by flexibly selecting a positioning standard according to the actual working condition on site; the surface treatment method can greatly reduce the manufacturing cost, improve the treatment efficiency and reduce the labor intensity while meeting the quality requirement of surface treatment.
