This standard is a revision of JB3624-84 "Basic Terms of Modular Clamp". The original version was formulated based on the structural characteristics of modular clamps and many years of production experience. 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 JB3624-84, and has only been re-edited according to relevant regulations. This standard replaces JB3624-84 from the date of implementation. This standard was proposed by the National Technical Committee for Standardization of Metal Cutting Machine Tools. This standard is under the jurisdiction of the Modular Jig Branch of the National Technical Committee for Standardization of Metal Cutting Machine Tools. The responsible drafting unit of this standard is Tianjin Modular Jig Research Institute. The main drafter of this standard is Lu Junkun.
This standard was first issued in October 1984. 1

Basic Terms of Modular Jigs
This standard specifies the general terms and assembly terms of modular jigs. This standard applies to the design, manufacture, assembly and use of modular jigs. 2 General Terms
2.1 Modular jig universal modular jig and fixture system JB/T3624-1999
Replaces JB362484wwW.bzxz.Net
It is composed of standardized and serialized fixture components that can be recycled and can be assembled into a fixture that is easy to connect and disassemble according to process requirements.
2.2 Structural elements
constructional element
Main substructures of modular fixture components, including the shape, size and relative position of the substructures, so as to unify design, manufacture and use.
Series system
In modular fixtures, products are distinguished by the positioning structure type between components. There are slot series modular fixtures and hole series modular fixtures. Variety type
In the same modular fixture series, products are divided according to different structural elements. For example, the slot series has varieties such as 1612, 8 and 6. Slot series modular fixture univasalmodularjigandfixturesystemwithslots2.5
A modular fixture that mainly determines the relative position between components by locating keys and slots. Hole series modular fixture univasalmodularjigandfixturesystemwithholes2.6
A modular fixture that mainly determines the relative position between components by locating pins and holes. 7 Elements
Standard components of combined fixtures designed for different purposes. 2. Base elements
Elements mainly used to assemble the fixture base. 2.9 Body elements
Elements mainly used to assemble into the concrete body of the fixture. 2.10 Positioning elements
Elements mainly used to determine the relative positions between elements and between elements and workpieces. Guiding elements
Elements mainly used to guide or determine the position of the tool. 2.12 Clamping elements
Elements mainly used to clamp the workpiece or other elements. Approved by the State Bureau of Machinery Industry on May 20, 1999 and implemented on January 1, 2000
2.13 Fasteners Fistening elements Elements mainly used to connect and fasten elements. 2.14 Miscellaneous demants JB/T3624-1999
