Embodiment 1

[0030]A method for detecting the quality of contact-type hole-making. The quality of the hole 3 to be measured is detected by the detection device extending into the hole 3 to be measured, and the stroke value and deformation amount of the detection device inserted into the hole 3 to be measured are recorded, which are used to calculate the hole to be measured. Measuring the diameter of the hole 3, the depth of the hole, the depth of the spot spot, and the radius of the spot spot; the detection device includes a detection unit, a connector 13, a first bushing 1, a second bushing 4, and a mounting seat 6, and the detection unit includes The probe 17, probe 16, conductor 12 and displacement sensor 18 are arranged in the connector 13 in order from left to right; the two ends of the outer side of the connector 13 are respectively connected to the first bush 1 and the second bush 4 , the first bushing 1 is connected to the conductor 12 through the connector 13, and the first bushing...

Embodiment 2

[0033] This embodiment is further optimized on the basis of embodiment 1, as figure 2 As shown, a compression spring 2 is arranged between the first bush 1 and the second bush 4, so that it can return to its original position after being contacted by force; the second bush 4 can slide relative to the mounting seat 6, and the The mounting seat 6 is provided with an elliptical hole, and the second bushing 4 is correspondingly provided with a round hole. The mounting seat 6 and the second bushing 4 are connected by a cylindrical pin 5, and the cylindrical pin 5 passes through the ellipse in turn. holes and round holes; the cylindrical pin 5 can move in the oval hole, so that the second bushing 4 can slide in the axial direction of the mounting seat 6;

[0034] Such as image 3 As shown, the side wall of the free end of the probe 17 is symmetrically provided with a through hole, the through hole is provided with a deformable block 9, one end of the deformable block 9 passes thro...

Embodiment 3

[0041] This embodiment is further optimized on the basis of Embodiment 2. The detection process of the detection device entering and exiting the hole 3 to be measured is mirrored, and the deformation amount of the deformable block 9 passing through the hole 3 to be measured is The deformable block 9 is completely compressed by the wall of the hole 3 to be measured to the stroke value of the detection device when the first bush 1 is just in contact with the hole 3 to be measured The stroke parameters of the detection device movement during the passage of the deformable block 9 through the hole 3 to be measured

[0042] In the detection method, the probe 17 is inserted into the hole 3 to be measured along the axial direction of the hole 3 to be measured until the first bush 1 cannot move relative to the connector 13, then the detection device returns to the hole 3 to be measured according to the opposite route, The displacement sensor 18 records the stroke value H2 of the de...

Abstract

The invention discloses a method of detecting contact hole quality. The method of detecting contact hole quality detects the quality of a hole to be detected by enabling a detecting device to extend into the hole to be tested, records the stroke value and the deformation amount of the detecting device extending into the hole to be tested, and is used for calculating the hole diameter, the hole depth, the dimple depth and the dimple radius of the hole to be tested. The detecting device includes a detecting unit, a connector, a first bushing, a second bushing, and a mounting base, wherein the detecting unit includes a probe, a probe, a conductor, and a displacement sensor which are disposed in the connector from left to right in order. The method of detecting contact hole quality detects andrecords the deformation value of the detecting device through a displacement sensor. The stroke value and the deformation amount which are obtained through detection of the method of detecting contact hole quality can be used for calculating the hole diameter, the hole depth, the dimple depth and the dimple radius of the hole to be tested. The method of detecting contact hole quality has the advantages of having few test parameters and effectively reducing the error. The method of detecting contact hole quality also has the advantages of being relatively higher in accuracy and stability of detection of hole quality, improving detection efficiency of hole quality, being able to realize on-line detection of hole quality, and having better practicality.

Description

technical field [0001] The invention belongs to the technical field of hole-making quality detection, and in particular relates to a contact-type hole-making quality detection method. Background technique [0002] Rivets are an indispensable connection method in aircraft assembly, so thousands of rivet holes need to be processed during parts processing. The quality of rivet holes will be closely related to the quality and life of aircraft parts, so the detection of rivet holes is very important. important. The current conventional method of rivet hole detection is to check with a plug gauge (go-no-go gauge). If the small end can pass, but the large end cannot pass, it is qualified. This method requires manual operation, and the workload is large, and the detection results are closely related to the strength and method of human operation. The detection accuracy is low and the stability is poor, which affects the accuracy and efficiency of hole measurement. Therefore, the pr...
