[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] Embodiment 1

[0036] This embodiment provides a centering adjustment device for realizing centering adjustment of a mating piece 1 and a mating piece 2 that are arranged relatively up and down. The centering adjustment device is used to change the horizontal position of the mating piece 1 so that its center is aligned with the center of the mating piece 2 as much as possible, so as to reduce the connection tolerance when the mating piece 1 and the mating piece 2 are connected.

[0037] like Figure 1As shown, the centering adjustment device includes a horizontal plate 3, a bearing mechanism 4, at least two horizontal fine-adjustment components 5 and a concentric component 6. The bearing mechanism 4 includes a first connecting member 41, and an upper adjustment plate 42 and a lower adjustment plate 43 arranged at intervals in the vertical direction. The first connecting member 41 can connect the upper adjustment plate 42 and the lower adjustment plate 43, so that when the position of the upper adjustment plate 42 is changed, the position of the lower adjustment plate 43 can be changed at the same time; the matching member 1 is arranged on the lower adjustment plate 43, and then when the position of the lower adjustment plate 43 is changed, the position of the matching member 1 can also be changed accordingly; the horizontal fine-adjustment component 5 can connect the horizontal plate 3 and the upper adjustment plate 42, and by performing a leveling operation on the horizontal fine-adjustment component 5, the level of the bearing mechanism 4 can be adjusted, which is convenient for the subsequent realization of the matching member 1 and the concentric component 6. The centering operation of the mating part 2 is performed because keeping it horizontal is a prerequisite for the centering operation; a concentric component 6 is provided between the upper adjustment plate 42 and the lower adjustment plate 43, and the concentric component 6 can make the lower adjustment plate 43 translate in the horizontal plane relative to the upper adjustment plate 42, so as to achieve the centering adjustment of the mating part 1 and the mating part 2, thereby reducing the connection tolerance when the mating part 1 and the mating part 2 are connected; and when the centering adjustment device is used later, the centering adjustment operation of the mating part 1 and the mating part 2 can be unified, avoiding the difference in the centering adjustment of the mating part 1 and the mating part 2 when manually holding, and improving the efficiency of the centering adjustment. Optionally, the mating part 2 can be a connector. Of course, the mating part 2 can also be other devices, which are not specifically limited in this embodiment.

[0038] The horizontal fine-tuning assembly 5 includes a second connecting member 51 and an inner hole bolt 52. The second connecting member 51 is a bolt structure, so that the second connecting member 51 has a head and a rod, and the rod has a thread; the second connecting member 51 is threadedly connected to the upper adjustment plate 42, so that after the second connecting member 51 is rotated, the depth of the second connecting member 51 screwed into the upper adjustment plate 42 can be adjusted; the inner hole bolt 52 is threadedly connected to the horizontal plate 3, so that after the inner hole bolt 52 is rotated, the depth of the inner hole bolt 52 screwed into the horizontal plate 3 can be adjusted; the rod of the second connecting member 51 is inserted into the inner hole bolt 52. The inner hole has a smooth inner wall, so that the second connecting member 51 will not form a threaded connection with the inner hole bolt 52, and the head of the second connecting member 51 is supported by the head of the inner hole bolt 52, thereby ensuring that the second connecting member 51 will not be separated from the inner hole of the inner hole bolt 52; the inner hole bolt 52 can be lifted and lowered relative to the horizontal plate 3, so that under the support of the inner hole bolt 52, the second connecting member 51 can also be lifted and lowered relative to the horizontal plate 3, and then the second connecting member 51 can drive the upper adjustment plate 42 to be lifted and lowered in the vertical direction, and adjust the distance between the horizontal plate 3 and the upper adjustment plate 42. Specifically, two, three or four horizontal fine-tuning components 5 can be set, and four are selected in this embodiment; each horizontal fine-tuning component 5 is located at a different position on the horizontal plate 3, and then according to the actual situation, by adjusting the distance between the horizontal plate 3 and the upper adjustment plate 42 at each horizontal fine-tuning component 5, the overall level of the bearing mechanism 4 can be adjusted, so as to facilitate the subsequent centering operation of the mating component 1 and the mating component 2.

[0039] like Figure 2 As shown, the concentric assembly 6 includes an upper matching ring 61, a ball 62 and a lower matching ring 63; grooves are provided at the lower part of the upper matching ring 61 and the upper part of the lower matching ring 63, and the ball 62 is simultaneously rolled in the grooves of the upper matching ring 61 and the lower matching ring 63, so that the lower adjustment plate 43 can be translated relative to the upper adjustment plate 42 in the horizontal plane by using the rolling of the ball 62 in the grooves of the upper matching ring 61 and the lower matching ring 63, and the level of the lower adjustment plate 43 can be ensured. The concentric assembly 6 between the upper adjustment plate 42 and the lower adjustment plate 43 is the first concentric assembly; the upper matching ring 61 of the first concentric assembly is arranged at the bottom of the upper adjustment plate 42, and the lower matching ring 63 is arranged at the top of the lower adjustment plate 43, so that the upper matching ring 61 is immovable relative to the upper adjustment plate 42 in the horizontal direction, and the lower matching ring 63 is immovable relative to the lower adjustment plate 43 in the horizontal direction; optionally, the groove in this embodiment is a triangular structure. Of course, the groove in this embodiment is not limited to a triangular structure, but may also be other structures that can realize the function of the concentric component 6.

[0040] like Figure 3As shown, the first connecting member 41 is a bolt structure, and the first connecting member 41 has a rod and a head; the upper adjustment plate 42 has a through hole, so that the rod of the first connecting member 41 can pass through the through hole and be fixedly connected with the lower adjustment plate 43, and at the same time, the head of the first connecting member 41 is supported on the upper adjustment plate 42, so that the lower adjustment plate 43 can be connected to the upper adjustment plate 42, avoiding the direct fall of the lower adjustment plate 43; a gap is provided between the hole wall of the through hole and the side wall of the rod of the first connecting member 41, so that the first connecting member 41 can be in the through hole along the Horizontally movable, since the first connecting member 41 is fixedly connected to the lower adjustment plate 43, the gap provides a movable space for the lower adjustment plate 43; the range of translation of the lower adjustment plate 43 relative to the upper adjustment plate 42 in the horizontal plane is the range of translation of the first connecting member 41 in the horizontal direction in the through hole; generally, the gap is small, which can avoid excessive deviation of the roller in the concentric component 6, and also avoid excessive horizontal translation of the lower adjustment plate 43 relative to the upper adjustment plate 42, thereby reducing the centering adjustment accuracy of the mating member 1 and the mating member 2.

[0041] like Figures 1 to 3 As shown, a concentric component 6 is also provided between the first connecting member 41 and the upper adjustment plate 42. The concentric component 6 between the first connecting member 41 and the upper adjustment plate 42 is a second concentric component. The lower mating ring 63 of the second concentric component 6 is provided on the lower adjustment plate 43, thereby ensuring that the lower mating ring 63 is immovable in the horizontal direction relative to the upper adjustment plate 42. The rod portion of the first connecting member 41 passes through the center of the second concentric component in the vertical direction, and the head of the first connecting member 41 is supported on the upper mating ring 61 of the second concentric component, thereby preventing the first connecting member 41 from being loosened. After the connecting piece 41 passes through the center of the second concentric assembly, the lower adjustment plate 43 connected to the first connecting piece 41 falls off; the second concentric assembly uses the rolling of the ball 62 in the grooves of the upper matching ring 61 and the lower matching ring 63 to realize the movement of the upper matching ring 61 relative to the lower matching ring 63, and then the upper matching ring 61 can drive the first connecting piece 41 that is in contact with the upper matching ring 61 to move, further increasing the activity space of the first connecting piece 41, so that the centering adjustment of the matching piece 1 and the piece to be matched 2 is more accurate. Among them, a gap can be generated in the vertical direction between the head of the first connecting piece 41 and the upper matching ring 61 of the second concentric assembly, so that the first connecting piece 41 has space for rising buffer, to prevent the upper matching piece 1 and the piece to be matched 2 from directly colliding with each other when there is no gap, which will cause damage to the matching piece 1 and the piece to be matched 2. Optionally, the rod portion of the first connecting member 41 passes through the center of the concentric assembly 6 between the upper adjustment plate 42 and the lower adjustment plate 43 in the vertical direction, thereby eliminating the need to set an additional first connecting member 41 to connect the upper adjustment plate 42 and the lower adjustment plate 43, thereby reducing the cost of manufacturing the equipment.

[0042] Embodiment 2

[0043] This embodiment also provides a magnetic attraction force detection device for detecting the magnetic attraction force of the magnetic mating part 2. The magnetic attraction force detection device includes the centering adjustment device in the above-mentioned solution 1, and also includes a base 7, a support frame 8 and a displacement module 9. Figure 4 As shown, a mating part 2 to be detected is provided on the base 7, a support frame 8 is provided on the base 7, a displacement module 9 is provided on the support frame 8, and the support frame 8 can support the displacement module 9 connected to the centering adjustment device, wherein the displacement module 9 is used to adjust the spatial position of the centering adjustment device connected to the driving end of the displacement module 9, so that the mating part 1 on the centering adjustment device and the mating part 2 to be mated are preliminarily aligned, thereby facilitating the subsequent use of the centering adjustment device to achieve accurate alignment of the mating part 1 and the mating part 2 to be mated.

[0044] like Figure 1 As shown, the mating part 1 includes a tension sensor 11 and a test head 12 disposed on the tension sensor 11. The tension sensor 11 is disposed on the lower adjustment plate 43. The test head 12 is used to magnetically engage with the mating part 2. After the test head 12 is pulled out, the tension sensor 11 can output the magnetic attraction force value of the mating part 2. Figures 4-5 As shown, the process of detecting the magnetic attraction force of the mating part 2 to be matched is: firstly, the matching part 1 and the mating part 2 to be matched are preliminarily adjusted by the displacement module 9, and then the matching part 1 is driven to move downward by the vertical drive module 91. In the process of connecting the matching part 1 and the mating part 2, the lower adjustment plate 43 can be displaced relative to the upper adjustment plate 42 under the action of the force generated by the abutment between the matching part 1 and the mating part 2, and then the matching part 1 and the mating part are accurately adjusted to be aligned, so that the test head 12 and the mating part 2 are magnetically attracted, and then the test head 12 is driven to move upward by the vertical drive module 91, wherein the tension sensor 11 can output the magnetic attraction force of the mating part 2 in this process, and the pressure sensing curve is made according to the collected magnetic attraction force, so as to judge whether the mating part 2 is qualified. Optionally, the magnetic mating part 2 to be matched can be a connector. Of course, the magnetic mating part 2 to be matched can be other devices, which are not specifically limited in this embodiment.

[0045] Furthermore, a positioning carrier 71 is provided on the base 7, and the positioning carrier 71 is used to carry the part to be matched 2, so as to position the part to be matched 2; the positioning carrier 71 includes a pressure plate 711, and the pressure plate 711 is used to press and fix the matching part 1 placed in the positioning carrier 71 to prevent the part to be matched 2 from shifting when being aligned and connected with the matching part 1, thereby affecting subsequent testing.

[0046] like Figures 4-5As shown, the displacement module 9 includes a vertical driving module 91 arranged on the support frame 8 and an XY-axis slide 92 arranged at the driving end of the vertical driving module 91. The output end of the XY-axis slide 92 is connected to the horizontal plate 3. Through the movement of the vertical driving module 91 in the vertical direction, the XY-axis slide 92 arranged at the driving end of the vertical driving module 91 can be driven to move in the vertical direction, so that the horizontal plate 3 connected to the output end of the XY-axis slide 92 can also be moved in the vertical direction. Among them, the XY-axis slide 92 can move the horizontal plate 3 connected to the output end of the XY-axis slide 92 in the horizontal direction, so that the spatial position of the centering adjustment device can be adjusted through the displacement module 9, and the spatial position of the matching component 1 can be further adjusted. Optionally, the XY axis slide 92 can be arranged on the support frame 8, the vertical drive module 91 can be arranged at the output end of the XY axis slide 92, and the horizontal plate 3 can be arranged at the drive end of the vertical drive module 91. Of course, this arrangement does not affect the adjustment of the position of the centering adjustment device by the displacement module 9. Further optionally, the magnetic attraction combined force detection device is provided with two centering adjustment devices to be applied to the magnetic attraction combined force detection of the parts 2 to be matched at two stations.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention.
