Assembly平板Operation Method
Generally, cast iron assembly platforms have a long service life. As long as they are used and stored properly, the precision of the work surface of the cast iron assembly platform can be maintained throughout its use.2Over one year, when the precision of the cast iron assembly platform decreases, it can be restored through adjustment or lapping processes. The service life of the cast iron platform itself can reach50-100Year, therefore, to extend the lifespan of the assembled cast iron platform, attention should be paid to the quality of work.
1During the use and storage of cast iron assembly platforms, be cautious not to use or store them in damp, corrosive, excessively high or low temperature environments.
2The cast iron platform should be cleaned thoroughly after assembly and properly rust-proofed.
Technical Requirements for Assembly of Tablet Technology
1The assembled flat work surface must not have defects such as sand holes, gas holes, cracks, inclusions, shrinkage cavities, scratches, dents, rust spots, etc., that significantly affect appearance and performance.
2The casting surface of the assembled flat plate should be properly sand-molded and smooth, with paint that is firmly adhered.
3Precision Registration:0Grade-3On a flat working surface of a grade, diameter less than15mmThe sand holes can be blocked with the same material, with a hardness less than that of the surrounding material. The number of sand holes to be blocked on the working surface should not exceed4Piece(s), and the spacing between sand holes should not be less than80mm。
4Please use flat assembly panels. Manufactured from fine gray cast iron or alloys, the working surface hardness should be170-220HB。
5The assembly of flat work surfaces typically should employ scraping techniques. For those utilizing scraping processing,3Graded flat work surface, with a roughness textureRaThe permissible values are:5um。
6Flatness tolerance is shown in the table.2Regulations.
7The surface treatment should undergo a coloring and fitting inspection. The ratio of the contact point area displayed after fitting is shown in the table.3Regulations: Or as specified25mm×25mmNumber of contact points for square area is shown in the table.3Regulations, and any25mm×25mmContact points should not exceed5Dot.
Assembly Process for Tablet Production
The production process of the assembly platform is basically:
One: Raw casting preparation on assembly platform: Draw technical drawings according to requirements, make wooden molds, material allocation, shaping, drying, casting, sand removal, cleaning, and inspecting all parts of the raw casting.
2. Assembly Platform Machining: Appearance inspection and marking, workpiece setup on machine, machining, inspection, and tempering.
Three: Mount machine tools on assembly platform, process according to drawings, and send for inspection to the Inspection Department.
4. Appearance treatment, painting, packaging, and inventory storage of the assembly platform
Assembled tablet processing technology
Assembled plates are a type of cast iron plate, but assembled plates are generally not flat; the surface of the platform must haveTFormed slots or holes, the general processing technology is as follows:
1Pre-process the reference surface.
The surface serving as the positioning reference during the processing of the parts First, process them to provide a precise reference for subsequent工序 processing. Weigh.
Please provide the Chinese content you would like translated into American English.“Benchmark First”。
2Divide into processing stages
Surfaces requiring high-quality processing are divided into processing stages, typically including rough, semi-fine, and fine processing. This is primarily to ensure processing quality; facilitate rational equipment use; arrange heat treatment procedures efficiently; and easily identify raw material defects in a timely manner.
3Pre-drilled after hole
For parts such as rectangular boxes, brackets, and rods, the flat surfaces should be machined before the holes. This allows for hole machining with flat surface positioning, ensuring precise alignment of the flat and hole, and facilitates the machining of holes on the flat surface.
4The finishing processes (such as honing, grinding, and polishing) on the main surfaces should be carried out at the stage of the process route to prevent damage to the finished surfaces due to transit and installation between operations.
Method for Assembling Flat Panel Identification
1The assembled flat work surface should be free of rust, scratches, dents, and other cosmetic defects that may affect usage.
2The assembly flat work surface should not have casting defects such as sand holes, gas holes, cracks, inclusions, and shrinkage porosity. All casting surfaces should be coated with molding sand, with smooth and even surfaces and sturdy paint, and all sharp edges should be rounded off.
3、TThe mold should have handles or lifting positions, threaded holes or cylindrical holes on the opposite sides of the flat plate. When setting the lifting positions, consider minimizing deformation caused by lifting.
4The assembled flat panels should be stabilized and degaussed.
5The assembled flat working surface and side surfaces, as well as the adjacent side surfaces, have vertical tolerances of12GradeGB1184—80"Dimensional Tolerance (as specified in 'Shape and Position Tolerance').”
6The hardness of the assembled flat work surface should be:HB170—220Or187—255Between.

Assembled Tablet Calibration
1As per the assembly flatness inspection regulation, visually inspect and test the appearance and surface quality.
2Compare the surface roughness of the sample blocks to check the surface roughness of the assembly flat's working surface and sides.
3With a graduation of2′Check side angle with the angle gauge.
4Determine the contact points of the scraping assembly plate using a calibration tool (accuracy not less than the assembly plate or level of the inspected assembly plate) via the coloring method.
5Select calibration tools based on the accuracy grade of the inspected flat plate, and inspect the flatness of the working surface of the assembled plate using the diagonal method.
6Certified plates that meet the assembly flat specification requirements are issued with a certification; those that do not comply with this procedure receive a certification result notice. The certification cycle for assembly flats is determined based on the specific usage, typically one year.
Assembly Flat Inspection Process
The assembled flat table is an indispensable workbench for marking, measuring, riveting, and fixture processes, and can also serve as a mechanical testing platform, etc. The production design of the assembly platform adopts box-type, ribbed plate, or other structural forms. On the opposite sides of the assembly flat table, there should be provisions for installation handles or hoisting positions, as well as threaded holes or cylindrical holes. After the assembled flat table is inspected and meets the standard requirements, it should be accompanied by a product qualification certificate; the product qualification certificate should include the standard number of this standard and the product serial number.
Throughout the entire inspection process of assembling the flat plate, the plate itself serves as the measuring base surface, and its placement should be stable. When using an autocollimator for calibration, the instrument and the plate should not be on the same rigid body. The rigidity of the instrument bracket is particularly important. Therefore, the inspection procedure for the assembly platform requires that the inspection site be firm and stable, and the inspection location should avoid vibrations. This is because: factories often place small flat plates on a lathe or on a table, which have poor stability. The movement of inspectors near the assembly platform and the movement of inspection tools on the platform can produce different gravitational forces, causing the spatial position of the assembly plate to change, resulting in inaccurate measurements. Therefore, when inspecting such flat plates, the plate should be moved to a firm and stable ground to avoid the impact of gravitational changes on the measurement results.
