Problems solved by technology

Some thin-walled disc-shaped parts have not yet been mass-produced during the trial manufacturing process, so special measuring tools cannot be used for testing in time, resulting in the inability to detect the depth of points on the slope of the part on the machine tool. If the part is removed from the fixture and sent to a three-coordinate instrument for testing , On the one

Embodiment Construction

[0018] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but the claimed protection scope is not limited to the description.

[0019] Such as figure 1 As shown, it is a high-pressure compressor disc part. Due to the large structural size of the part, the outer circle size of the part is The size of the inner hole is The thinnest part wall thickness is only 2.5mm. upper web There is a point with a depth reading of 26.025 on the inclined surface. Before the special measuring tool arrives, the depth of this point cannot be detected on the machine tool. If the part is disassembled and sent for three-coordinate detection, it will cause the part to be deformed in secondary clamping. It is a difficult point to detect the depth of the point on the slope on the machine tool.

[0020] In order to solve this difficulty, combined with the characteristics of CNC machine tools and dial indicator or dial indi...

Abstract

The invention discloses a disk part oblique plane point depth measuring method and device. The device comprises a dial gauge or a clock gauge; and the dial gauge or the clock gauge is connected with aturret of a numerical control machine tool through a magnetic gauge stand. During measurement, a surface of a disk part is selected, and the surface is located between a to-be-measured point and theturret of the numerical control machine tool; the turret is moved until the dial gauge or the clock gauge on the turret touches the selected surface, the dial gauge or the clock gauge is zeroed, and aZ-axis coordinate value of the numerical control machine tool is reset; and the turret is moved again until the dial gauge or the clock gauge on the turret touches the to-be-measured point, it is confirmed that the dial gauge or the clock gauge reads zero, and the Z-axis coordinate value of the numerical control machine tool is the depth value of the to-be-measured point at the moment. The depthof the point is rapidly measured without disassembling the disk part or using a special measuring tool.

Description

technical field [0001] The invention belongs to the field of aero-engine manufacturing, in particular to a method and a device for measuring the depth of a point on a web slope of a thin-walled disk part during machine tool processing. Background technique [0002] At present, in the manufacturing process of aero-engines, the processing of many thin-walled disk parts is involved. Some thin-walled disc-shaped parts have not yet been mass-produced during the trial manufacturing process, so special measuring tools cannot be used for testing in time, resulting in the inability to detect the depth of points on the slope of the part on the machine tool. If the part is removed from the fixture and sent to a three-coordinate instrument for testing , On the one hand, it will cause the lengthening of the production cycle of the parts. On the other hand, in the aero-engine manufacturing industry, most of the parts are thin-walled parts. During the disassembly process, if the clamping f...
