This standard specifies the accuracy requirements and inspection methods of the multi-station mobile worktable (hereinafter referred to as "worktable") of a combined machine. This standard is applicable to the working methods of combined machine tools and their automatic lines. 2 Reference standards
The texts contained in the following standards are not applicable to this standard and are not included in this standard. At the time of publication of this standard, the provisions shown in the standard are effective. All standards will be revised. Parties using this standard should explore the possibility of using the latest versions of the following standards. GB/T1742.11998 Machine without inspection, clause 1 Part: Geometry of machine tools without pornography or precision machining 3 Brief description
3.1 The nominal size of the worktable is the sliding width of the corresponding worktable 3.2 When using this standard, the relevant provisions of GB 17421.1 shall apply. 3.3 The order of precision inspection items listed in this standard does not represent the actual inspection order. In order to reduce the installation of inspection tools and facilitate inspection, inspections can be carried out in any order.
3.4 ​​The inspection tools and instruments specified in this standard are of a punching nature: production 4. Any other inspection tools and instruments may be used under the premise of ensuring the inspection quality. bZxz.net
35 In the inspection items using a straight ruler, the two supports of the straight ruler should be in the best support position, that is, the corresponding 5/9 of the length of the ruler to minimize the self-stirring of the flat ruler.
3.6 Place the workbench on the half plate and use a feeler gauge to check the difference between the bottom surface of the slide and the flat plate. For general-grade workbenches, use a 0.04mm feeler gauge, for precision-grade workbenches, use a 0.03mm feeler gauge, and for high-precision workbenches, use a 0.02mm feeler gauge. The insertion length of the feeler gauge shall not exceed 5m. After passing the test, carry out various precision tests for accuracy numbers G1-G5. 3.7 The test of geometric accuracy numbers G6 and G7 is carried out on the test bench. Approved by the State Administration of Industry and Information Technology on May 20, 1999 and implemented on January 1, 2000
