Embodiment 1

[0055] Such as figure 1 As shown, the detection device of the present invention includes two major components: an indicator 2 and a complete set of gauges 1 . In actual use, the complete set of gauges 1 is in contact with the inner taper hole of the tested part 3 (see Figure 9 ) and the axial displacement is accurately reflected on the indicator 2 in a ratio of 1:1 to realize the acquisition of detection data.

[0056] The indicator 2 is matched with the complete set of gauge 1 through the gap between the hole and the shaft, and it is ensured that the indicator 2 can move smoothly on the handle shaft 1-1 of the complete set of gauge 1 .

[0057] When in use, when the "0" position of the coordinate engraved line on the indicator 2 falls between the two engraved lines on the complete set of gauge 1, it can be judged that the taper size accuracy, shape accuracy, and position accuracy are qualified; the "0" position of the coordinate engraved line on the indicator 2 When it fal...

Abstract

The present invention relates to a high-precision multi-cone deep hole detection device and a detection method, and belongs to the technical field of mechanical processing inspection. The detection device includes: an indicator (2) and a set gauge (1), where the indicator is used to indicate whether a test piece (3) is qualified by a reading; and a central opening, where the outermost side of thebig end matches a hole shape of the end of the test piece, the step surface is centrally vertical to the shape of the outermost side, the small end is a slender shaft, a plane is milled at a positionL4 from the lamination surface of the indicator, L4 is the origin 0 of coordinates, and 10 lines of 1 mm are engraved from the upper left and the lower right. The set gauge is used to measure the testpiece, and includes a handle shaft (1-1) and a cone-shaped column (1-4), the cone-like column is matched with the measured cone hole, and the handle shaft is cooperatively inserted into the center hole of the indicator through the clearance and slides therein, and two alignment lines L1 and L2 are engraved on the handle shaft along the circumference according to the calculated size. Compared withthe prior art, the device of the present invention is easy to process, install and use, has low costs and high durability; and the measurement method is stable and reliable, and the measurement is accurate.

Description

technical field [0001] The invention relates to a high-precision multi-cone deep hole detection device and a detection method, belonging to the technical field of mechanical processing inspection. Background technique [0002] The barrel is an important part of a certain equipment, and the drug chamber is a key part of the barrel. It is a high-precision multi-taper deep hole, and its manufacturing quality directly affects the final performance of the product. The space of the drug chamber should conform to the volume value of the drug chamber determined during the design of the inner ballistic. The structure should adapt to the characteristics of the filling method and the shape of the cartridge. After manufacturing and forming, it should meet the requirements of dimensional accuracy, shape accuracy, and surface roughness. cartridge. [0003] It is a technical difficulty in barrel processing to detect after the drug chamber is processed. Therefore, it is necessary to design...
