Granite bed components

Granite bed components are suitable for the on-site working environment, and have the characteristics of product accuracy for a long time. They can determine the accuracy of processing and testing in the working environment and the quality of working products. Especially for measurement with appropriate accuracy

granite bed components are generally used for the worktable of measuring instruments. Granite bed components and marble components have the advantages of good precision, no deformation, high strength and good hardness. It can be processed and customized according to different needs of customers

granite bed component is a kind of physical measuring tool made of marble material. It is a kind of instrument with fixed shape when in use, which is used to reproduce or provide quantitative one or more known quantities. For example, weights, standard batteries, color temperature lamps, resistors, gauge blocks, signal generators and (single value or multi value, with or without scale) gauges are all measuring tools

marble measuring tools generally include: Marble testing platform, marble ruler, marble square ruler, marble square box, marble V-block, marble comparison platform, etc. It is applicable to the datum plane for various inspection work and precision measurement. It is used for the mechanical inspection and measurement datum of machine tools, checking the dimensional accuracy or behavior deviation of parts, and marking. The marble gantry bed component is also an excellent basic tool in mechanical manufacturing

precautions for mechanical assembly of granite bed components:

1. Clean and clean the parts. The cleaning work includes removing the residual casting sand, rust, chips, etc. In particular, some important parts, such as gantry large cutting machine and inner cavity, shall be coated with antirust paint. The oil stain, rust or attached chips on the parts can be cleaned with diesel, kerosene or gasoline as washing solution, and then dried with compressed air

2. Lubricant shall be added to the matching surface before matching or connection. In particular, the bearing part in the spindle box and the screw nut part of the lifting mechanism

3. The fitting size of matching parts shall be accurate, and the fitting size shall be rechecked or sampled during assembly. For example: the matching part of the journal and bearing of the main shaft, the matching hole and its center distance between the spindle box and the bearing

4. For the assembly of the wheel, the axis lines of the two toothed wheels shall be in the same plane and parallel to each other, with normal meshing clearance and axial dislocation of 2mm

5. The joint surface of the connection shall be checked for flatness and deformation, otherwise it shall be trimmed and deburred, and the contact of the joint surface shall be close, flat and not skewed

6. The seal shall be pressed into the sealing groove in parallel without distortion, damage and scratch on the sealing surface

7. The assembly requirements of the pulley are that the axes of the two pulleys should be parallel, and the center of the pulley groove should be positive. If the deviation is too large, the tension of the pulley will be uneven, resulting in belt slippage and accelerated wear. At the same time, the V-belt shall be selected and matched before assembly, and the length shall be consistent to prevent vibration in transmission
