Foreword
JB/T6702--2004
This standard is a revision of JB/T6702--1993 "Tractor Product Drawings and Design Document Numbering Rules". At the time of revision, the writing format of this standard complies with the provisions of GB/T1.1-2000 (Standardization Work Guidelines Part 1: Standard Structure and Writing Rules). Compared with JB/T6702-1993, the main changes are as follows: In the standard name Modifications were made;
emphasized in the scope that this standard does not apply to the numbers of standard parts and rolling bearings in product drawings: - changes were made in the layout, adding a basic requirement: and specifically refining the Content. - Added requirements on whether interchangeability will be lost after improvement in the drawing serial number preparation; - Added two first-level component codes
This standard replaces JB/T6702--1993. Appendix A and Appendix B of the standard are normative appendices. This standard is proposed by the China Machinery Industry Federation. This standard is drafted by the National Tractor Standardization Technical Committee and participated by the Gansu Provincial Agricultural Machinery Appraisal Station. Drafting. The main drafters of this standard are: Han Meixiao, Yang Qinshou, and Shang Xiangsheng. The previous versions of the standards replaced by this standard are: -ZB T60 002--1987, JB/T 6702-1993.II||tt ||p-3-
Scope
Numbering rules for tractor product drawings and design documents This standard specifies the numbering rules for tractor product drawings and design documents. This standard applies to the numbering of tractor product drawings and design documents. . 2 Basic requirements
2.1 The drawings of parts and components of each product should have independent drawing codes (referred to as drawing numbers). 2.2 The parts and components of each specification listed in the table and drawings should be numbered independently. Drawing number. JB/T6702--2004
2.3 In the multi-scheme assembly drawing of partially changed parts and components in the series design or variant design, an independent drawing number should be assigned to each scheme shown. 2.4 Borrowed parts. The original drawing number should be used for the drawings. 2.5 Parts and components used in multiple models of series products or variant products should be assigned only one drawing number. 2.6 Separately drawn system diagrams and principles should be treated as borrowed parts when used in other models. Drawings, motion diagrams, etc. should be numbered according to the range of components shown. 2.7 When drawings of parts and components of the same product are drawn on several drawings, each drawing should be marked with the same drawing number in the title column of the drawing. The serial number should be indicated in "Total × sheets" and "No. It consists of three segments of generation (serial) numbers separated by dots below: complete machine code
part code
pattern serial number
3.1.1 The complete machine code is the code indicating the ownership of the drawing. The product model can be simplified to represent. 3.1.2 The component code is a code that indicates the affiliation of the product drawing. It is generally numbered to the first-level component. When it is necessary to distinguish the drawings of first-level components (including the complete machine) with different structures and the drawing number capacity needs to be expanded, When specifying a secondary component, the number of digits can be increased, and its composition is in the form: xx
x
X
There is no such code structure distinction mark for grade components, and they are represented by uppercase English letters (avoid using I, O, and Z). Do not leave spaces when there is no distinguishing mark
-level component code, which is used for various types of drawing numbers according to Appendix A (Normative Appendix) stipulated in 3.1.3 drawing serial number. 3.1.3.1 Drawing serial number partition: complete machine and --level component drawings: 001-009: sub-component drawings: 011-099: parts drawings: 101-9993.1.3.2 When parts are improved in design on the original design drawings, they lose interchangeability , then add "-1" "-2" 3" after the original drawing serial number to indicate the changed order. If interchangeability is still maintained, add the uppercase English letters "A\, "B" after the original drawing serial number , "C"·indicates the changed order. 3.1.3.3 When the parts lose their interchangeability after the design is improved on the original design drawing, "-1" will be added after the original design drawing serial number; but after the second improved design is made and the interchangeability with the first improved drawing is maintained, then Add "-IA\" after the serial number of the original design drawing; if the interchangeability is still maintained after the third improved design, add "-1B" after the serial number of the original design drawing. 1
