Description

TECHNICAL FIELD

[0002] In order to be able to remove the frost on the propeller blade of the helicopter in the cold environment, the conductive ring is usually installed on the bottom end outer periphery of the propeller hub, and the defrosting is carried out by using the conductive ring to generate heat. Since the propeller blade is in a high-speed rotating state during the flight of the helicopter, the installation precision of the conductive ring on the propeller hub has an influence on the conductivity of the conductive ring, therefore, during the maintenance of the helicopter, the radial runout and the axial runout of the conductive ring on the propeller hub are necessary indexes for the overhaul and maintenance.

The lower detection mechanism comprises a second radial displacement sensor 91 and an axial displacement sensor 92, the axial displacement sensor 92 can move radially reciprocatingly along the fifth vertical plate 96 through the sixth vertical plate 97, so that the radial position adjustment of the axial displacement sensor 92 is realized, so as to achieve the axial runout detection of the conductive ring with different sizes.

[0004] However, in the above technical solution, since the axial displacement sensor 92 can only move linearly reciprocatingly, the installation angle of the axial displacement sensor 92 cannot be adjusted, and it can only be applied to the axial runout detection of the conductive ring with a flat end face, and the detection of the conductive ring with an inclined end face installed on the propeller hub cannot be carried out, so the versatility is poor.

[0030] The utility model will be made further detailed explanation in combination with the specific implementation of the description drawings and the drawings.

[0031] Referring to the drawings Figure 1 to the drawings Figure 2 It is shown that the embodiment provides a conductive ring run-out detection tool 10, which comprises a rack 100, a control box 200, a hub positioning seat 400 and a conductive ring run-out detection device 300. The control box 200 is arranged on the upper end face of the rack 100, and the hub positioning seat 400 is fixedly installed on the upper end face of the rack 100. The hub positioning seat 400 is used for installing and placing the hub 20 of the propeller to be detected. The conductive ring run-out detection device 300 is arranged on the upper end face of the rack 100. The conductive ring run-out detection device 300 is used for detecting the radial run-out amount of the fairing centering sleeve on the upper end of the hub 20 of the propeller to be detected and the radial run-out amount and axial run-out amount of the conductive ring on the lower end.

[0032] Referring to the drawings Figure 1 and the drawings Figure 2 It is shown that in the embodiment, the conductive ring run-out detection device 300 comprises a sliding plate 301, a shaft sleeve radial sensor mounting plate 305, a shaft sleeve radial displacement detection sensor 302, a conductive ring radial displacement detection sensor 303, a conductive ring axial detection laser sensor 304, a displacement sensor pad 306, a connecting rod mechanism 307 and a locking bolt 308.

[0033] The bottom end of the sliding plate 301 is slidingly installed on the upper end surface of the rack 100, for example, a sliding rail and a sliding block are installed between the bottom end of the sliding plate 301 and the upper end surface of the rack 100, and the sliding direction of the sliding plate 301 is parallel to the length direction of the rack 100, that is, the sliding plate 301 can move close to or away from the hub positioning seat 400. The power of the sliding plate 301 is provided by the driving unit 500 provided, such as a pneumatic cylinder or an electric motor, which is not limited.

[0034] Referring to the accompanying drawings Figure 3 and the accompanying drawings Figure 7 As shown in the drawings, the shaft sleeve radial sensor mounting plate 305 is installed on the outer edge side of the top end of the sliding plate 301, the shaft sleeve radial displacement detection sensor 302 is installed on the shaft sleeve radial sensor mounting plate 305, and the shaft sleeve radial displacement detection sensor 302 is used to detect the radial runout amount of the fairing centering shaft sleeve of the upper end of the hub of the propeller to be detected. The conductive ring radial displacement detection sensor 303 is installed on the bottom end of the sliding plate 301, and is used to detect the radial runout amount of the conductive ring at the bottom end of the hub of the propeller.

[0035] In this embodiment, the shaft sleeve radial displacement detection sensor 302 is a non-contact laser displacement sensor. Since the outer peripheral surface of the fairing centering shaft sleeve of the upper end of the hub of the propeller to be detected is not a smooth cylindrical surface, but is spliced by three bushings, there is a gap between adjacent bushings, so the non-contact laser displacement sensor is used for detection, which has higher accuracy.

In some embodiments, a vertical long strip-shaped mounting hole 3061 is formed around the displacement sensor pad 306, and when the displacement sensor pad 306 is installed on the sliding plate 301, the locking bolt 308 passes through the long strip-shaped mounting hole 3061 to lock and fix the displacement sensor pad 306 on the sliding plate 301. The long strip-shaped mounting hole 3061 is provided to flexibly adjust the installation height position of the displacement sensor pad 306 on the sliding plate 301 during use, that is, the displacement sensor pad 306 can be moved and adjusted in the height direction by loosening the locking bolt 308, and after being moved and adjusted to the required height position, the locking bolt 308 is tightened to fix the displacement sensor pad 306 on the sliding plate 301.

[0037] Referring to the accompanying drawings Figure 4 to the accompanying drawings Figure 6As shown, the connecting rod mechanism 307 is hingedly installed on the side of the displacement sensor pad 306, the connecting rod mechanism 307 can rotate up and down relative to the displacement sensor pad 306, the conductive ring axial detection laser sensor 304 is fixedly installed on the connecting rod mechanism 307, and the connecting rod mechanism 307 is fixedly installed on the displacement sensor pad 306 through the locking bolt 308.

[0038] By installing the conductive ring axial detection laser sensor 304 on the displacement sensor pad 306 in the manner of the connecting rod mechanism 307, the connecting rod mechanism 307 can rotate up and down relative to the displacement sensor pad 306, so that the connecting rod mechanism 307 can drive the conductive ring axial detection laser sensor 304 thereon to adjust the installation angle, so as to adapt to the axial detection of the conductive ring with different detection end face shapes, for example, when the axial runout detection of the conductive ring with a flat end face is detected, the conductive ring axial detection laser sensor 304 is adjusted to be horizontally installed; when the axial runout detection of the conductive ring with an inclined end face is detected, the conductive ring axial detection laser sensor 304 is adjusted to be obliquely installed; the axial runout detection of the conductive ring with a flat end face or an inclined end face can be met, and the versatility is good.

[0039] Referring to the accompanying drawings Figure 5 As shown, specifically, the connecting rod mechanism 307 includes a first connecting rod 3071, a second connecting rod 3072 and a third connecting rod 3073, the upper end of the first connecting rod 3071 is provided with a waist-shaped hole 30711, the lower end of the first connecting rod 3071 is hingedly installed on the outer side of the displacement sensor pad 306, one end of the second connecting rod 3072 is hingedly installed on the first connecting rod 3071 between the upper end and the lower end of the first connecting rod 3071, the other end of the second connecting rod 3072 is hingedly connected with one end of the third connecting rod 3073, the other end of the third connecting rod 3073 is hingedly installed on the outer side of the displacement sensor pad 306, the third connecting rod 3073 rotates along the outer side of the displacement sensor through the sliding mechanism 309 provided, the conductive ring axial detection laser sensor 304 is fixedly installed on the second connecting rod 3072, and the locking bolt 308 is locked on the displacement sensor pad 306 through the waist-shaped hole 30711.

[0040] Referring to the accompanying drawings Figure 4 and the accompanying drawings Figure 5As shown, when the installation angle of the electric ring axial detection laser sensor 304 needs to be adjusted, the locking bolt 308 can be loosened, so that the first connecting rod 3071 can rotate relative to the displacement sensor pad 306. The operator moves the electric ring axial detection laser sensor 304, so that the first connecting rod 3071, the second connecting rod 3072 and the third connecting rod 3073 are linked and rotated. After moving to the installation angle of the electric ring axial detection laser sensor 304 desired by the operator, the locking bolt 308 is tightened to lock and press the first connecting rod 3071 on the displacement sensor pad 306, preventing the first connecting rod 3071 from rotating in position, and ensuring the stability of the installation position of the electric ring axial detection laser sensor 304.

[0041] Referring to the accompanying drawings Figure 4 and the accompanying drawings Figure 5 As shown, specifically, in the present embodiment, the sliding mechanism 309 includes a rod-shaped sliding rod 3092 and a sliding groove 3091.

The sliding rod 3092 is arranged so that the third connecting rod 3073 can slide along the opening direction of the sliding groove 3091.
