[0019] Example 1

[0020] like Figure 1 A planetary gear testing device shown is composed of a horizontal testing platform 100, a PLC controller 105, a rotating platform assembly and a testing assembly;

[0021] The rotating platform assembly includes bearing grooves 102 and shaft mounting holes 103 provided on both sides of the horizontal inspection platform 100, bearings 110 provided in the bearing grooves 102, a motor frame 101 provided on the bottom surface of the horizontal inspection platform 100, a power motor 106 provided on the motor frame 101, a coupling 107 provided on the power motor 106, a vertical shaft 108 installed in the horizontal inspection platform 100 through the bearings 110 and the shaft mounting holes 103, and a circular discharge plate 111 provided at one end of the vertical shaft 108, one end of the vertical shaft 108 being connected to the coupling 107;

[0022] The detection assembly includes a vertical L-shaped frame 104 arranged on one end surface of the horizontal detection platform 100, a hydraulic cylinder slot 113 arranged in one end of the vertical L-shaped frame 104, a hydraulic cylinder frame 114 arranged on one end surface of the vertical L-shaped frame 104 and located above the hydraulic cylinder slot 113, a vertical hydraulic cylinder 115 installed on the hydraulic cylinder frame 114, a screw 116 arranged at one end of the vertical hydraulic cylinder 115, a strip-shaped horizontal plate 117 with through holes used in conjunction with the screw 116, a screw nut 118 for fixing the strip-shaped horizontal plate 117 with through holes to the screw 116, and a first 3D camera 119 and a second 3D camera 120 symmetrically arranged on both end surfaces of the strip-shaped horizontal plate 117 with through holes;

[0023] The power motor 106 , the vertical hydraulic cylinder 115 , the first 3D camera 119 , and the second 3D camera 120 are respectively connected to the PLC controller 105 .

[0024] The working principle is:

[0025] (1) Place multiple planetary gears to be tested in a horizontal ring shape on the outer layer of the circular discharge plate 111;

[0026] (2) The vertical hydraulic cylinder 115 is started by the PLC controller 105, and the vertical hydraulic cylinder 115 drives the screw 116, the horizontal plate with through holes 117, the first 3D camera 119, and the second 3D camera 120 to move downward synchronously. After reaching the appropriate position, the vertical hydraulic cylinder 115 is stopped by the PLC controller 105;

[0027] (3) The power motor 106 is started by controlling the PLC controller 105, and the power motor 106 rotates slowly. At this time, the coupling 107 links the vertical shaft 108 to drive the circular discharge plate 111 to rotate. The rotating circular discharge plate 111 rotates the multiple planetary gears to be detected and passes under the first 3D camera 119 and the second 3D camera 120 in turn. At this time, the first 3D camera 119 and the second 3D camera 120 complete the secondary scan of the planetary gears. The parameter information of the secondary scan is fed back to the PLC controller 105, and the PLC controller 105 stores it and transmits it to the upper analytical instrument component. After the scan is completed, the power motor 106 is controlled to stop by the PLC controller 105, and the circular discharge plate 111 on which the multiple planetary gears to be detected are placed in a ring-shaped horizontal direction can be moved away.

[0028] Example 2

[0029] On the basis of the first embodiment, the planetary gear detection device further includes a wear-resistant limiting sleeve 109 disposed in the shaft mounting hole 103 and used in conjunction with the vertical shaft 108;

[0030] The wear-resistant limiting sleeve 109 is used to provide limiting protection for the slowly rotating vertical shaft 108 to ensure the stability and safety of the detection and measurement.

[0031] Example 3

[0032] On the basis of Example 1 or Example 2, Figure 3 The planetary gear detection device shown also includes a plurality of planetary gear placement grooves 112 provided in an outer layer of one side of a circular discharge plate 111;

[0033] The sizes of the planetary gear placement slots 112 are the same or different, so that different planetary gears to be measured can be stably placed to prevent them from escaping from the slowly rotating circular discharge plate 111 .

[0034] Example 4

[0035] On the basis of embodiment 1, embodiment 2 or embodiment 3, Figure 2 The planetary gear detection equipment shown also includes a circular limiting ring 122 arranged on one side of the horizontal detection platform 100 and located on the outer layer of the bearing groove 102 and used in conjunction with the circular discharge plate 111, a limiting convex ring 125 arranged on the outer layer of the circular discharge plate 111, a circular discharge plate clamping groove 123 arranged on the inner wall of the circular limiting ring 122, and a limiting groove 124 arranged in the circular discharge plate clamping groove 123 and used in conjunction with the limiting convex ring 125.

[0036] The above-mentioned design structure can provide stable support and limitation for the slowly rotating circular discharge plate 111 during horizontal rotation, thereby improving the accuracy of detection and scanning parameter acquisition and the stability of the circular discharge plate 111 during rotation.

[0037] Example 5

[0038] Based on the first embodiment, the second embodiment, the third embodiment, or the fourth embodiment, the planetary gear detection device further includes a distance measuring sensor 121 provided on one side of the strip-shaped horizontal plate 117 with a through hole and located between the first 3D camera 119 and the second 3D camera 120;

[0039] Among them, the ranging sensor 121 is connected to the PLC controller 105, so that when the PLC controller 105 controls the vertical hydraulic cylinder 115 to start moving downward, the safety of the vertical downward control of the horizontal strip with through holes 117 is achieved, preventing the occurrence of downward transition and squeezing damage to the first 3D camera 119 and the second 3D camera 120, thereby achieving safe vertical control.

[0040] In the planetary gear detection device of this structure, the PLC controller 105, the power motor 106, the vertical hydraulic cylinder 115, the first 3D camera 119, the second 3D camera 120 and the distance sensor 121 are all conventional components and will not be described in detail in this application.
