This standard is a revision of JB3627.784 "Copper hammer for assembly of modular clamps". The original version was formulated according to the production characteristics of modular clamps, and its technical content can still meet the current scientific and technological level and meet the needs of production and use. This standard is consistent with the technical content of JB3627.7—84, and has only been re-edited according to relevant regulations. This standard is part of the series of standards for tools and accessories for assembly of modular clamps. JB/T3627 "Tools and accessories for assembly of modular fixtures" includes the following 11 parts under the general title: Part 1 (i.e. JB/T3627.1): Hexagonal wrench Part 2 (i.e. JB/T3627.2): Electric wrench hexagonal head Part 3 (i.e. JB/T3627.3): T-shaped four-jaw wrench Part 4 (i.e. JB/T3627.4): Electric wrench four-jaw head Part 5 (i.e. JB/T3627.5): Four-jaw wrench Part 6 (ie JB/T3627.6): lever part 7 (ie JB/T3627.7): copper hammer part 8 (ie JB/T3627.8): drilling fixture inspection rod part 9 (ie JB/T3627.9): boring fixture inspection rod part 10 (ie JB/T3627.10): hollow boring fixture inspection rod part 11 (ie JB/T3627.11): connection plate This standard replaces JB3627.784 from the date of implementation. This standard is proposed by the National Technical Committee for Standardization of Metal Cutting Machine Tools. This standard is under the jurisdiction of the National Technical Committee for Standardization of Metal Cutting Machine Tools, modular fixture branch. The responsible drafting unit of this standard: Tianjin modular fixture factory assembly station. The main drafter of this standard: Li Guiyu.
This standard was first issued in May 1984.
