In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.

[0028] Although the terms first, second, etc. are used to represent various elements in this article in some examples, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, the first interface and the second interface, etc. are represented.

The singular form used herein also includes the plural form unless the sentence clearly indicates the contrary meaning. The meaning of "including" used in the specification is to specify specific characteristics, regions, integers, steps, operations, elements and / or components, and does not exclude the existence or addition of other characteristics, regions, integers, steps, operations, elements and / or components.

Terms defined in commonly used dictionaries are additionally interpreted as having meanings consistent with relevant technical literature and the message of the present disclosure, and shall not be overly interpreted as ideal or very formal meanings unless defined.

[0031] The parts to be tested are the plane bearing and the gasket assembled in the planet carrier. The correct assembly method is to place a plane bearing first and then a gasket. However, the existing assembly process is prone to the wrong assembly of directly placing two gaskets, and the height of the two stacked gaskets is the same as the height of the stacked plane bearing and gasket, which ultimately leads to the transmission being burned due to high temperature during subsequent use, GS1 sintering, and the transmission function failure.

[0032] Based on the above problems, an embodiment of the present disclosure provides a detection device to detect whether the plane bearing and the gasket are correctly placed after they are placed in the planetary carrier, so as to improve the accuracy of transmission assembly.

[0033] Figure 1 The figure shows the overall structure of the detection device, the part to be tested and the supporting mechanism in the embodiment of the present disclosure. Figure 1 In the example, the detection device is arranged corresponding to a carrying mechanism for carrying the part to be tested and capable of driving the part to be tested to a predetermined position to be tested.

[0034] Here we first call Figure 4 , combined with Figure 1 and Figure 4 For example, the detection device includes a detector 10 and a comparator 20. The detector 10 includes a movable detection end 11, and the detection end 11 is set at a position that can be squeezed by the detected part of the part to be tested that reaches the predetermined position to be tested, so that the detector 10 outputs a detection signal corresponding to the first displacement formed by the extrusion of the detection end 11. The comparator 20 is electrically connected to the detector 10, and performs a comparison between the first displacement and the preset displacement based on the detection signal to obtain a detection result of whether the thickness of the detected part is qualified. The present disclosure moves the assembled planetary carrier 100 to the position to be tested of the detection end 11, and after the detection end 11 arrives at the position to be tested, it is obtained by comparing the displacement of the detection end 11 with the preset displacement to determine whether the plane bearing and the gasket 200 are correctly assembled in the planetary carrier 100, thereby reducing subsequent repairs and replacements caused by unqualified assembly.

[0035] Figure 2 FIG. 2 is a schematic diagram of the overall structure of two cushion members 200 stacked in an embodiment of the present disclosure. Figure 2In the example, the two cushions 200 are not tightly attached after being stacked, but there is a certain gap between the detected parts of the two cushions 200. When the bearing mechanism transports the part to be tested to the specified position, the detection end 11 of the detector 10 abuts against the detected part of the upper cushion 200, and the upper cushion 200 tilts due to the force on one side, which eventually causes the first displacement of the detection end 11 to be reduced compared with the preset displacement. The comparator 20 compares the first displacement with the preset displacement to obtain the detection result that the assembly of the part to be tested is unqualified.

[0036] Exemplarily, the bearing mechanism is a tray with a positioning function. Exemplarily, the bearing mechanism drives the part to be tested to a predetermined position to be tested in a vertical direction to prevent the stacked plane bearing and the cushion 200 from falling off the part to be tested, which ultimately leads to inaccurate test results or test failure. In another embodiment, for example, when the plane bearing and the cushion 200 are fixed to the planetary carrier 100, the moving direction may be a horizontal direction or other directions.

[0037] Exemplarily, the detected part is located on a cushion 200 detachably placed on the part to be detected, and a change in the number of the cushions 200 stacked causes a change in the thickness of the detected part, that is, a change in the thickness of the detected part causes a change in the first displacement.

[0038] In some embodiments, the detection device can also measure other incorrect assemblies, for example, stacking two pads 200 on a plane bearing, such incorrect assembly causes the first displacement of the detection end 11 to increase compared to the preset displacement; placing the pad 200 first and then placing the plane bearing, such incorrect assembly causes the first displacement of the detection end 11 to have an error with the preset displacement.

[0039] Figure 3 The figure shows a cross-sectional view of the displacement sensor in the embodiment of the present disclosure. Figure 3 In the example, the detector 10 is implemented as a displacement sensor. Those skilled in the art will appreciate that the displacement sensor can convert physical quantities such as displacement, position, size, etc. of an object into a measurable electrical signal or other forms of signal output.

[0040] Figure 4 The figure shows a schematic diagram of the separation of the overall structure of the detection device in the embodiment of the present disclosure. Figure 4In the example, the detection device further includes a mounting assembly 60, and the mounting assembly 60 includes a mounting bracket 61 and a mounting block 62. The mounting bracket 61 is arranged corresponding to a bearing mechanism for carrying a part to be tested and driving the part to be tested to a predetermined position to be tested, the mounting block 62 is arranged on the mounting bracket 61 with an adjustable horizontal position, and the detector 10 is arranged on the mounting block 62 with an adjustable height. Exemplarily, the mounting bracket 61 is implemented as an inverted L-shape to avoid the annular planetary carrier 100. In another embodiment, the mounting bracket 61 can also be implemented as other shapes that can avoid the annular planetary carrier 100, but is not limited thereto.

[0041] exist Figure 4 In the example, one end of the mounting bracket 61 is penetrated to form a mounting slot 6101, and the mounting block 62 is formed with at least one mounting hole 6201, and the length and width of the mounting slot 6101 are both greater than the aperture of the mounting hole 6201. In another embodiment, there are multiple mounting holes 6201, and the multiple mounting holes 6201 are spaced apart along the length direction of the mounting slot 6101, and the distance between the two outermost mounting holes 6201 is less than the length of the mounting slot 6101; or, the multiple mounting holes 6201 are spaced apart along the width direction of the mounting slot 6101, and the distance between the two outermost mounting holes 6201 is less than the width of the mounting slot 6101. The bolt passing through the mounting hole 6201 has space to move in the horizontal position, so as to realize the adjustable horizontal position of the mounting block 62. Exemplarily, the length direction of the mounting slot 6101 can be the left-right direction or the front-back direction in the horizontal state.

[0042] In another embodiment, two cross-shaped slide grooves are formed at one end of the mounting bracket 61, and a mounting hole is formed on the mounting block 62. The width of the slide groove is adapted to the diameter of the mounting hole, and the length of the slide groove is greater than the diameter of the mounting hole. For example, the two cross-shaped slide grooves can be implemented in a horizontal plane or in a vertical plane, and the specific implementation method is determined by the direction that actually needs to be adjusted.

[0043] Figure 5 The figure shows a cross-sectional view of the mounting block in the embodiment of the present disclosure. Figure 4 and Figure 5For example, the mounting block 62 has a mounting end 621, and the top wall of the mounting end 621 penetrates in the vertical direction to form a first fixing hole 62101 for inserting the detector 10. The wall surface of the mounting end 621 parallel to the axial direction of the first fixing hole 62101 is formed with an adjustment groove 62102 that is connected to the first fixing hole 62101 and vertically penetrates, and the other wall surface of the mounting end 621 adjacent to the wall surface is formed with a first bolt hole 62103 that is axially perpendicular to the axial direction of the first fixing hole 62101 and passes through the adjustment groove 62102, and an adjustment bolt (not shown in the figure) is screwed into the first bolt hole 62103.

[0044] It can be understood by those skilled in the art that when the adjusting bolt is tightened, the spacing of the adjusting slots 62102 is reduced. At this time, since the adjusting slots 62102 are connected to the first fixing holes 62101, the aperture of the first fixing holes 62101 is reduced as the spacing of the adjusting slots 62102 is reduced, so that the inner wall of the first fixing hole 62101 gradually clamps the detector 10, and finally the relative fixation of the detector 10 and the mounting block 62 is achieved. On the contrary, when the adjusting bolt is loosened, the aperture of the first fixing hole 62101 is reduced as the spacing of the adjusting slots 62102 is reduced. Exemplarily, a cushion is provided on the inner wall of the first fixing hole 62101 (not shown in the figure) to prevent the inner wall of the first fixing hole 62101 from causing extrusion damage to the detector 10 when the spacing of the adjusting slots 62102 is reduced.

[0045] In another embodiment, the mounting block 62 has a mounting end 621, and a second fixing hole is formed by penetrating the top wall of the mounting end 621 in the vertical direction. Exemplarily, the aperture of the second fixing hole is larger than the outer diameter of the detector 10. A second threaded hole connected to the second fixing hole is formed on the side wall of the mounting end 621 perpendicular to the top wall, and a bolt is threadedly connected to the second threaded hole. After the height of the detection end 11 of the detector 10 is determined, one end of the bolt located in the second fixing hole can abut against the outer wall of the detector 10, thereby fixing the position of the detector 10. Exemplarily, a rubber pad is provided on the end of the bolt abutting against the outer wall of the detector 10 and the inner wall of the second fixing hole to prevent the bolt from damaging the detector 10.

[0046] Figure 6 The circuit structure diagram of the detection device in the embodiment of the present disclosure is shown in FIG. Figure 6In the example, the detection device further includes a control unit 30 and an alarm 40. The detector 10 is electrically connected to the control unit 30. For example, the control unit 30 integrates a display and a control panel for easy operation and viewing by staff. The alarm 40 is electrically connected to the control unit 30, and the comparator 20 is electrically connected to the control unit 30. For example, the comparator 20 is implemented as being built into the control unit 30. After receiving the unqualified detection result obtained by the comparator 20, the control unit 30 issues an alarm signal that causes the alarm 40 to implement an alarm action to prompt the staff that the part to be tested is unqualified. For example, the alarm 40 can be implemented as at least one of an alarm light, an alarm horn and a buzzer. For example, the detection device further includes a PLC unit 50, which is communicatively connected to the control unit 30. To control the overall operation of the detection device.

[0047] In yet another embodiment of the present disclosure, an assembly device is provided, comprising the above-mentioned detection device, for assembling a transmission including a planet carrier 100 .

[0048] The calculation parts involved in the comparator 20 and the detector 10 in this application belong to the prior art, so this application does not involve software improvement.
