Description

Technical Field

[0001] The present invention relates to the technical field of strength detection, and particularly to a strength detection device for a differential housing. Background Art

[0002] The differential housing is an important part of the differential, and its main function is to support and protect the internal parts of the differential such as planetary gears and axle gears.

[0100] When detecting the strength of the differential housing, the operation steps of those skilled in the art are as follows:

[0101] Step 1: Place the differential housing on the circular plate 21. Then, use the first cylinder 23 to make the lower pressing plate 24 and the side pressing plate 25 extrude the bottom end of the differential housing, so as to fix the differential housing;

[0102] Step 2: Use the first servo motor 20 to rotate the circular plate 21 so that the differential housing is directly below the left cylinder body 31. Then, use the second cylinder 30 to make the cylinder body 31 contact the circular plate 21. At this time, the differential housing will be located in the cylinder body 31;

[0103] Step 3: When it is necessary to place the differential housing in a dusty environment, first adjust the position of the dust discharge pipe 64 through the adjustment assembly and the fourth servo motor 53. Then, dust will fall on the differential housing through the dust discharge pipe 64 via the dust inlet pipe 61. Thus, a dusty environment can be simulated in the left cylinder 31. When it is necessary to place the differential housing in a humid environment, first adjust the position of the atomizing nozzle 63 through the adjustment assembly and the fourth servo motor 53. Then, water will fall on the differential housing through the drain pipe 62 via the water inlet pipe. Thus, a humid environment can be simulated in the left cylinder 31. When it is necessary to place the differential housing in a vibrating environment, first adjust the position of the second annular plate 71 through the adjustment assembly to make the second annular plate 71 contact the differential housing. Then, the differential housing will be vibrated by the first vibration motor 73. Thus, a vibrating environment can be simulated in the left cylinder 31. When it is necessary to place the differential housing in a high-temperature environment, first adjust the position of the second hollow tube 80 through the adjustment assembly and the fourth servo motor 53. Then, hot air will be sprayed on the differential housing through the cooperation of the fan 81 and the electric heating wire 82. Thus, a high-temperature environment can be simulated in the left cylinder 31.

[0104] Step 4: When the time for the differential housing in the left cylinder 31 reaches the preset value, the circular plate 21 will be rotated by the first servo motor 20 to place the differential housing directly below the right cylinder 31. Then, the cylinder 31 will be made to contact the circular plate 21 by the second cylinder 30. At this time, the differential housing will be located in the cylinder 31.

[0105] Step 5: When it is necessary to conduct a compressive strength test on the differential housing, first align the bearing plate 91 with the position to be tested through the adjustment assembly. Then, the corresponding hemispherical blocks 93 will be moved towards the differential housing by the fifth cylinder 92 until the shape formed by the several hemispherical blocks 93 matches the shape of the position to be tested. At this time, the differential housing will be compressed by the compression assembly through the fourth cylinder 90 until the pressure sensor reaches the set value range. Thus, a compressive strength test can be conducted on the differential housing. In addition, repeating the above steps can also conduct an impact strength test on the differential housing. When it is necessary to conduct a vibration strength test on the differential housing, first align the bearing plate 91 with the position to be tested through the adjustment assembly. Then, the lower circular plate 96 will be moved towards the differential housing by the sixth cylinder 94. Then, the differential housing will be vibrated by the second vibration motor 991. Thus, a vibration strength test can be conducted on the differential housing.
