JB/T8362.1—1997
The standard is formulated on the basis of reference to the precision inspection list of the gear machine in the United States, France, and other countries, and in accordance with user requirements and the actual situation of existing products in China. This standard is proposed by the National Technical Committee for Standardization of Metal Cutting Machine Tools, and is under the jurisdiction of Tianjin Gear Machine Tool Research Institute. The drafting unit of this standard is Tianjin Gear Machine Tool Research Institute. 1 Scope
Machinery Industry Standard of the People's Republic of China
Precision Inspection of Bevel Gear Quenching Machines
Technical standard specifies the requirements and methods for the axial degree and working accuracy of industrial gear quenching machines: 4 The standard is applicable to large-scale industrial/1 chain tooth range with a diameter of 830~1250mm, 2 Reference standard
JB/T 8362.1997
The provisions contained in the following standard are incorporated into this standard by introduction. When the standard is published, the version shown is valid. All the above standards will be effective. The parties who use this standard should discuss the possibility of revising the two standards. JB2671-82 3.1 The requirements for the inspection of cutting machine tool dimensions must refer to B2670, especially the installation inspection method and the precision inspection method before the inspection. 3.2 The inspection license of JB2673-82 3.1 The whole machine tool is installed horizontally, the workbench is in the working position, and the reading of this instrument in the longitudinal and lateral directions is every 0.06/100. 3.3 During the inspection, the inspection order can be conveniently considered. 3.4 When the actual length is different from the length specified in this standard, it shall be converted according to the provisions of 2.3.1.1 of JB267C-82 according to the length that can be measured. When the conversion result is less than 0.01mm, it is still calculated as 0.01mm. Heterogeneous fine failure inspection

JB/T 8362.1-1997 Inspection Items Verticality of worktable axis to worktable surface (This inspection is used for machine tools where the expander cone is replaced at the bottom and E is positioned with the positioning hole at the center of the worktable) Strictness of the expander base A to the worktable surface. The expander for inspection is placed on the lower die, and is positioned with the surface and the positioning holes of the three workbench centers. The machine tool of the f-1000 indicator is used for inspection. Please refer to the relevant provisions of JB2670--82 for workbench center positioning! Insert the test sample into the center of the well and position it on the steel ball. Fix the indicator on the test rod and stop its probe from touching the work surface. The error of the indicator is calculated by the maximum value of the indicator reading. Indicator: In the center of the work table: Install the test plate: Install the test plate in the center of the work table and make the bottom of the test plate fit closely with the base surface. Fix the indicator on the plate and make it touch the work surface. The error is determined by the maximum value of the indicator sensitivity JE/T8362.1-1997. Inspection items: upper mold center piston tot line and working center setting hole indicator inspection sample inspection check 0.080 inspection modification Inspection method: follow the relevant provisions of JB207088, workbench and upper die working position. (1) The expander cone is on the lower die, and the machine tool is positioned at the work center: a steel ball is placed in the work center positioning hole, and the test piece is inserted into the center positioning hole and pressed against the steel ball. The problem is indicated on the test needle, so that it is aligned with the center piston rod of the upper die, and the test is performed. The error is calculated as half of the maximum difference of the indicator value.
(2) Machine tools with expander cone on the upper die:
Fix the indicator on the center live rod of the die, and light the upper center plunger mark. For machines that cannot rotate, a quick inspection indicator can be installed on its piston rod, and its probe and the workbench block can be fixed with a fixed inspection hole. Then, rotate the center live rod (or inspection sleeve) of the die for inspection. t||The error is measured by the indicator reading. (3) The expander is placed on the mold, and the expander is positioned with reference A and the center of the workbench. The inspection plate is installed in the center of the workbench. The lower pin of the plate fits tightly with the reference A. The indicator on the inspection plate is pressed against the head of the instrument. 5. Working accuracy inspection JH/T 8362 1 1997 Inspection items: The upper pressure die can be tested on the working surface by multiplying the points on the center piston card. This instantaneous inspection method is used for the main mold indicator on the tensioner tank car. The relevant provisions of J8270·2 are as follows: The center of the mold is inspected by the rotating inspection disk. 5. 5. 1. 2 The error is calculated by the difference of the indicator reading. For the machine tool with the main crimping center working case not being able to rotate, a test piece can be installed on its piston rod. Fix the indicator on the test machine so that its head touches the lower working table and the upper die working pot is rotated. The error is calculated by the difference of the indicator reading. The conditions for the machine tool working precision inspection (size, material and quantity of the test piece, etc.) and the technical requirements to be met shall be determined by the manufacturer and the user.
