Problems solved by technology

[0003] Although it is convenient to manually observe whether the drilling holes are included in the drilling holes through the drilling holes, the distance between the drilling holes and the drilling holes is far away, and the difference in diameter between the two holes is too large, which makes the detection results extremely difficult. Unreliable, and the test results cannot be quantified
However, the existing rapid detection tool can only determine whether the deviation hole position can be corrected, but the specific correction area cannot be known after the detection tool is removed, making subsequent correction operations inconvenient
In addition, the laser tracker is used to detect the deviation of the hole position by measuring the spatial coordinates of the center of each hole-making hole and the center of the drilling mold hole, and judging whether there is a deviation in the hole-making hole according to these two coordinates. This detection method has a high detection accuracy. , but when detecting a large number of hole-making deviations, there are problems such as high equipment cost, inconvenient detection and low efficiency
[0004] Therefore, in view of the defects in the existing hole-making deviation detection device and method that the detection accuracy of manual visual inspection is insufficient, the inspection of ordinary hole-making tools cannot know the hole-making correction area, and the laser detection cost is high and the efficiency is low, the present invention discloses A device and method for rapid detection of hole position deviation

Abstract

The invention discloses a device for quickly detecting a hole site deviation. The device comprises a detection pin arranged at one end of a handle. A positioning cone is coaxially arranged at one endof the detection pin, an observation hole penetrating through the detection pin and the positioning cone is arranged in the detection pin along an axis, and a calibration pen is arranged on an end surface of one end of the positioning cone. The invention further discloses a method for quickly detecting the hole site deviation. A detection pin is inserted into a drill jig hole, the observation holearranged in the detection pin is used for directly observing a hole forming hole site so as to determine whether the hole forming hole site can be subjected to hole site deviation correction or not,meanwhile, a series of detection pins with the observation holes with the hole diameters which are sequentially increased are arranged to detect the hole forming hole site, and therefore quantification of the hole forming hole site is achieved. Meanwhile, the subsequent hole site deviation correction area is subjected to remembering calibration through the calibration pen; the device and the method have beneficial effects of simple operation, high detection efficiency, high detection precision, and capabilities of quantifying the hole site deviation and calibrating the hole site deviation correction area.

technical field [0001] The invention belongs to the technical field of hole position deviation detection, and in particular relates to a device and method for fast detection of hole position deviation. Background technique [0002] Hole-making processing operation is generally a key step in the assembly process of aviation products. A large number of connection structures in aviation products need to be connected by hole-making, riveting and other processes, especially for holes with multiple holes on the surface of the connection structure. In terms of bit processing, it should be ensured that the hole positions of the interconnected parts are coordinated and consistent. Therefore, it is a key link in the hole making process to effectively and reliably detect the correctness of the machining hole position through the corresponding detection technology, and this operation is of great significance to ensure the assembly quality of the aircraft. In the process of hole making,...
