[0024] It should be noted that when an element is described as being "fixed, fixed, connected or connected to" another element, it can be directly fixed, fixed, connected or connected to the other element, or it can be indirectly fixed, fixed, connected or connected to the other element through other intermediate connectors.

[0025] Unless otherwise defined, all the professional terms used below have the same meanings as those generally understood by those skilled in the art. The professional terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the scope of protection of the present invention. Example

[0026] like Figure 1 and Figure 2 A planetary carrier orientation machine shown in the figure includes an inner support clamping mechanism 2 and a rotation orientation mechanism 3, both of which are arranged on a frame 1, a first motion component 4 is arranged on the frame 1, and the inner support clamping mechanism 2 is arranged on the first motion component 4; the rotation orientation mechanism 3 includes a servo electric cylinder 31, a connecting frame 32, a connecting block 33, a center rod 34 and an orientation component 35, the connecting block 33 is fixedly arranged at the lower part of the center rod 34, the center rod 34 is fixedly connected to the connecting frame 32, and the servo electric cylinder 31 is connected to the connecting frame 32. The top of the center rod 34 is connected to the servo motor 36, and the servo motor 36 drives the center rod 34 to rotate; the orientation assembly 35 is arranged on the connection block 33; the orientation assembly 35 includes an orientation pin 351, an orientation spring 352, a sliding shaft 354 sleeve 353 and a sliding shaft 354, the top of the orientation pin 351 is fixedly connected to the sliding shaft 354, the sliding shaft 354 is arranged in the sliding shaft 354 sleeve 353, the sliding shaft 354 sleeve 353 is fixedly connected to the connection block 33, and the orientation spring 352 is arranged between the orientation pin 351 and the connection block 33. In this embodiment, an orientation spring limiting rod 355 is arranged on the connection block 33, and the orientation spring 352 is arranged on the orientation spring limiting rod 355.

[0027] In this embodiment, when the planet carrier 8 is oriented, the planet carrier 8 is mounted on the inner support clamping mechanism 2 and clamped by the inner support clamping mechanism 2. The inner support clamping mechanism 2 moves the planet carrier to the lower side of the inner support clamping mechanism 2 for orientation under the movement of the first moving assembly 4. During orientation, the servo electric cylinder 31 drives the center rod 34 to drive the connecting frame 32, the connecting block 33 and the orientation assembly 35 to move downward as a whole, so that the orientation pin 351 presses downward against the upper end surface of the planet carrier; after the orientation pin 351 contacts the upper end surface of the planet carrier, the servo electric cylinder 31 drives the center rod 34 to continue to press down 10-20mm, so that the orientation spring 352 is in a compressed state; then the servo motor 36 drives the center rod 34 to rotate, and the orientation pin 351 is inserted into the pin hole of the planet carrier under the action of the orientation spring 352. The servo motor 36 stops rotating and the inner support clamping mechanism 2 is released. At this time, the planetary carrier is not clamped. The servo motor 36 of the rotating orienting mechanism 3 drives the orienting pin 351 inserted into the pin hole to rotate the planetary carrier to the required direction of the planetary carrier pin hole. At this time, the inner support clamping mechanism 2 is clamped again, and the orientation of the entire planetary carrier is completed; the servo electric cylinder 31 drives the connecting frame 32, the connecting block 33 and the orienting assembly 35 to move upward and reset as a whole.

[0028] In this embodiment, a detection assembly 5 is provided on the orientation assembly 35, and the detection assembly 5 includes a detection block 51 and a photoelectric sensor 52. The detection block 51 is fixedly arranged on the upper part of the sliding shaft 354, and the photoelectric sensor 52 is arranged on one side of the detector facing the detection block 51. In this embodiment, since the detection block 51 is fixedly connected to the sliding shaft 354, when the orientation pin 351 enters the pin hole of the planetary frame, or when the servo electric cylinder 31 drives the orientation assembly 35 to move upward and reset as a whole, the detection block 51 will move up and down in position, and the photoelectric sensor 52 located on one side of the detection block 51 can detect the position change of the detection block 51, thereby making the servo motor 36 stop rotating or the servo electric cylinder 31 stop contracting. In this embodiment, the detection block 51 can be an annular block.

[0029] In this embodiment, the first motion assembly 4 includes a first slide rail 41, a first slide seat 42 and a first base 43. The inner support clamping mechanism 2 is arranged on the first base 43. The first base 43 is fixedly arranged on the first slide seat 42. The first slide seat 42 is arranged on the first slide rail 41. The bottom of the first base 43 is connected to the first cylinder 44. In this embodiment, the first motion assembly 4 drives the inner support clamping mechanism 2 to move on the frame 1.

[0030] In this embodiment, if Figure 3 and Figure 4The inner support clamping mechanism 2 shown includes a clamping jaw 21 assembly, a linear rail 22, a cylinder 23 and an outer cone top column 24, the outer cone top column 24 is arranged in the cylinder 23, the cylinder 23 is arranged in the accommodating cavity formed by the clamping jaw 21 assembly, the inner side surface of the clamping jaw 21 of the clamping jaw 21 assembly is formed with an inclined surface matching the outer cone top column 24, and the inner side of the bottom of the clamping jaw 21 assembly is formed with a horizontal plate 212 supporting the cylinder 23. A top block 25 is arranged on the inclined surface of the clamping jaw 21, and the arrangement of the top block 25 is mainly arranged when the distance between the top of the outer cone top column 24 and the inclined surface of the inner side surface of the clamping jaw 21 assembly is large.

[0031] The clamping jaw 21 assembly includes three or four relatively arranged clamping jaws 21. In this embodiment, four clamping jaws 21 are taken as an example, and multiple steps 211 are arranged on the clamping jaw 21; each step 211 corresponds to a planet carrier 8 with a different inner hole diameter, so as to be suitable for different models of planet carriers 8.

[0032] In this embodiment, four clamps 21 are mounted on the slider of the linear rail 22. The tail ends of the four clamps 21 are pushed inward by the clamp springs 26. The four clamps 21 are pressed against the outer wall of the cylinder 23 by the directional springs 352, so as to keep the positions in their respective directions consistent. After the planetary carrier is placed on the clamp 21 by the feeding robot (not shown in the figure), the inner diameter of the clamped planetary carrier and the circle formed by the four clamps 21 in the corresponding natural state have only a gap of 0.2mm. After being placed, the outer cone top column 24 under the clamp 21 drives the cylinder to push the outer cone top column 24 upward, and the outer cone surface of the outer cone top column 24 contacts the four clamps 21, so that the four clamps 21 support the inner hole of the planetary carrier at the same time, thereby achieving the effect of centering clamping. After clamping, the inner support clamping mechanism 2 runs from the feeding position to the bottom of the rotating directional mechanism 3 to orient the pin hole of the planetary carrier.

[0033] In this embodiment, if Figure 5 and Figure 6 As shown, five orientation components 35 are arranged on the connecting block 33, so that five different planetary carriers can be used; an orientation component 35 switching device is arranged on the frame 1 and the orientation component 35, and the orientation component 35 switching device includes a second motion component 6 and a locking sleeve component 7 arranged on the orientation component 35; the servo electric cylinder 31 is arranged on the second motion component 6, and the second motion component 6 is arranged on the connecting frame 32.

[0034] In this embodiment, if Figure 7As shown, the lock sleeve assembly 7 includes an unlocking cylinder 71, a push pin cylinder 72, an unlocking sleeve 73, a steel ball 74, and a limit block 75. The steel ball 74 is arranged between the sleeve 353 of the sliding shaft 354 and the limit block 75, and the limit block 75 is fixedly arranged on the upper part of the sliding shaft 354; the unlocking sleeve 73 is arranged on the outside of the steel ball 74, and the lower part of the unlocking sleeve 73 is provided with an unlocking spring 76, and the lower part of the unlocking spring 76 is connected to the connecting block 33 or the outer protrusion of the sleeve 353 of the sliding shaft 354; the unlocking cylinder 71 and the push pin cylinder 72 are arranged on the side of the frame 1 opposite to the inner support clamping mechanism 2 to form a switching position, and the unlocking cylinder 71 is provided with a lower pressing block of the unlocking sleeve 73, and the push pin cylinder 72 is arranged at the lower part of the positioning pin. As shown Figure 1 As shown, the second motion assembly 6 includes a second slide rail 61, a second slide seat 62 and a second base 63. The servo electric cylinder 31 is arranged on the second base 63. The second base 63 is fixedly arranged on the second slide seat 62. The second slide seat 62 is arranged on the second slide rail 61. The second base 63 is connected to the second cylinder. In this embodiment, four positioning rods 321 are arranged on the top of the connecting frame 32. The four positioning rods 321 pass through the second base 63, and the four positioning rods 321 can move up and down on the second base 63.

[0035] In this embodiment, when the directional assembly 35 is switched, the second cylinder drives the second base 63 to move. Since the servo cylinder 31, the connecting frame 32, the connecting block 33, the center rod 34 and the directional assembly 35 are all connected to the second base 63, they will move with the second base 63. When the directional assembly 35 needs to be switched, the directional assembly 35 is moved to the switching position for switching.

[0036] In this embodiment, when switching, the servo motor 36 first turns the directional pin 351 that needs to be replaced and withdrawn from use to the replacement direction, and then the servo electric cylinder 31 drives the connecting frame 32, the connecting block 33 and the directional assembly 35 to descend to the replacement height as a whole; at this time, the pressing block on the unlocking cylinder 71 presses down the unlocking sleeve 73 above the directional assembly 35 to unlock the steel ball 74, so that the sliding shaft 354 can move, and then the pin-pushing cylinder 72 lifts the directional pin 351, and after the detection block 51 is sensed in place, the unlocking cylinder 71 rises to release the unlocking sleeve 73, and locks the raised directional pin 351 again, and the pin-pushing cylinder 72 descends and resets, so that the current directional assembly 35 enters the waiting position. Afterwards, the second cylinder drives the rotary orienting mechanism 3 to rise back to the working position, and then the rotary orienting mechanism 3 turns the directional pin 351 required for the type change to the type change direction, and then the second cylinder drives the rotary orienting mechanism 3 as a whole to move to the type change position, at this time the unlocking cylinder 71 presses down the unlocking sleeve 73 above the orienting component 35 to unlock, and at this time the orienting component 35 extends into the working position under the action of the orienting spring 352, and the unlocking cylinder 71 rises to release the unlocking sleeve 73, so that the type change is successful.

[0037] The planetary carrier orienting machine of this embodiment does not require manual intervention to achieve the orientation of the planetary gears, thereby being suitable for the automated assembly of the planetary gears; at the same time, the orientation pins of the planetary carrier orienting machine of the present invention can be replaced to be suitable for different models of planetary carriers, thereby saving costs and space.
