General technical conditions for heavy machinery
Part 10. Assembly
1 Scope
This part of GB/T 37400 specifies the general requirements for the assembly of heavy machinery products, the geometric tolerances of the assembled components, and the assembly connections.
General technical requirements for methods, typical component assembly, final assembly, inspection and commissioning, disassembly.
This section applies to the assembly of heavy machinery products.

3 General requirements for assembly
3.1 Parts and components that enter the assembly (including purchased parts and external parts) shall have the certificate of the inspection department for assembly.
3.2 Parts should be cleaned and cleaned before assembly, without burrs, flash, scale, rust, chips, oil, colorants, rust preventive oil and
Dust, etc.
3.3 Before assembly, the main matching dimensions of the parts and components, especially the interference fit size and related accuracy, should be reviewed. Trimmed by fitter
The size of the fit should be reviewed by the inspection department.
3.4 The mechanical processing in the assembly process shall comply with the relevant provisions of GB/T 37400.9; the welding procedure shall comply with GB/T 37400.3
Relevant regulations.
3.5 In addition to special requirements, the sharp corners and sharp edges of the parts should be blunt before assembly.
3.6 Parts are not allowed to bump, scratch and rust during assembly.
3.7 The hole of the conveying medium should be checked by lighting or ventilation method.
3.8 Primers and topcoats should be applied first after assembly. Parts and parts that are not dry may not be assembled.
3.9 The basic parts of the machine, the fuselage, etc., should be level (or vertical) when assembled. Correction accuracy, for machines with simple structure and low precision
The machine is not less than 0.1mm/m; the machine with complicated structure and high precision is not less than 0.05mm/m.
3.10 Zero with relative motion, each lubricating point on the component should be filled with appropriate amount of lubricating oil (or grease) after assembly.
4 Geometric tolerances of the assembled parts
4.1 This geometric tolerance refers to the unfilled geometric tolerance of the measured component of the assembled component. The main parameter is L≤1000mm. See Table 1, main parameters.
