[0016] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0017] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] like Figure 1-2 As shown, a grasping device for a planetary gear wire material tray includes a grasping device and a fixing device; the grasping device includes a plurality of grasping mechanisms arranged circumferentially on a main frame 101, and the fixing device is arranged on a first bottom plate 501; after the grasping device contacts the fixing device, the fixing device is separated from the fixed object, and the grasping mechanism grasps the fixed object.

[0019] Specifically, in this example, the fixed object is the planetary gear 4. When the grasping device is not in contact with the fixing device, the clamping plate 504 clamps the planetary gear 4 under the elastic force of the spring 8. The clamping plate 504 and the positioning cylinder 506 work together to fix the planetary gear on the second base plate 502. When the grabbing device is working, the cylinder 2 pushes the slide bar 302 outward so that the horizontal distance from the grabbing part 303 to the main frame 101 is slightly larger than the radius of the planetary gear 4. The slide tube 102 of the grabbing device is aligned with the guide rod 601. When moving downward, the slide tube 102 contacts and drives the collar 602 to move downward. The connecting end of the rotating rod 701 and the collar 602 moves downward, and the other end pushes the slide bar 702 to move away from the guide rod 601. The push rod 703 fixedly connected to the slide bar 702 moves in the direction away from the guide rod 601. The push rod 703 pushes the clamping plate 504 away from the planetary gear 4. As the grabbing device moves downward, the recessed portion 304 of the grabbing part 303 is flush with the planetary gear 4. The cylinder 2 pushes the slide bar 302 outward so that the grabbing part 303 is aligned with the planetary gear 4. 2 shrinks inwards so that the recessed portion 304 is in close contact with the planetary gear 4. At the same time, the pressing block 103 presses the top of the planetary gear 4 under the elastic action of the compression spring 3. The pressing block 103 and the grasping portion 303 jointly fix the planetary gear 4. Thereafter, the grasping device moves upward to make the planetary gear 4 separate from the second bottom plate 502. As the slide cylinder 102 moves upward, the tension spring 902 pulls the sliding rod 702 toward the direction close to the guide rod 601, and the rotating rod 701 connected thereto moves accordingly, pushing the sliding sleeve 602 to move upward, and the push rod 703 also moves toward the direction close to the guide rod 601. The pressing plate 504 flips inwards (towards the guide rod 601) under the action of the spring 8.

[0020] In addition, the grabbing mechanism includes a connecting rod 301 fixedly arranged on the main frame 101, a sliding rod 302 is slidably arranged on the connecting rod 301, a grabbing portion 303 is vertically arranged at the bottom of the sliding rod 302, a recessed portion 304 adapted to the planetary gear 4 is arranged on the grabbing portion 303, and a protective film 305 is arranged in the recessed portion 304; a cylinder 2 is arranged on the main frame 101, and the output end of the cylinder 2 is connected to the sliding rod 302. The protective film 305 can be made of elastic materials such as rubber, and the function of the protective film 305 is to increase friction to facilitate grabbing, and at the same time prevent wear caused by direct contact between the recessed portion 304 and the planetary gear.

[0021] In addition, the grasping device also includes a slide 102 arranged at the bottom of the main frame 101, and the outer side of the slide 102 can be slidably connected to the clamping block 103. The slide 102 is sleeved with a compression spring 3, and the compression spring 3 is respectively connected to the bottom of the main frame 101 and the top of the clamping block 103. The slide 102 is slidably connected to the guide rod 601.

[0022] In addition, a guide rod 601 penetrating through the second bottom plate 502 is fixedly provided at the center of the first bottom plate 501, and the fixing device includes a collar 602, a rotating rod 701, a sliding rod 702, a push rod 703 and a pressing plate 504. The collar 602 is slidably provided on the guide rod 601, and the collar 602 is rotatably connected to one end of a plurality of rotating rods 701 in the circumferential direction, and the other end of the rotating rod 701 is rotatably connected to one end of the sliding rod 702, and the other end of the sliding rod 702 is fixed Connect one end of the push rod 703, and the other end of the push rod 703 passes through the through slot 503 set on the second bottom plate 502 and then connects to the clamping plate 504. The first bottom plate 501 is provided with a plurality of vertical plates 505 in the circumferential direction, and a spring 8 is provided on the top of the vertical plate 505. The spring 8 connects the vertical plate 505 and one end of the clamping plate 504. The clamping plate 504 is rotatably connected to one end of the spring 8 and the vertical plate 505, and the other end of the clamping plate 504 is connected to the planetary gear 4. An adaptive through hole is provided in the center of the second bottom plate 502. ① Here, the sliding sleeve 602 can be set to move only at the bottom of the second bottom plate 502, and ② can also be set to move within the range of the top and bottom of the second bottom plate 502 (at this time, the through hole needs to meet the activity requirements of the rotating rod 701). For example, ① the length of the slide cylinder 102 will exceed the gear aperture size of the planetary gear 4, which may affect the subsequent placement. The push rod 703 is tilted, wherein the vertical height of the end connected to the clamping plate 504 is higher than the end connected to the sliding rod 702, and the vertical height of the end of the push rod 703 in contact with the clamping plate 504 is higher than the connection point between the vertical plate 505 and the clamping plate 504 (at this time, the push rod 703 can only push the clamping plate 504 to rotate counterclockwise when it moves to the left (such as Figure 1The pressing plate 504 cooperates with the spring 8 to make the pressing plate 504 tend to move toward the planetary gear 4. The size of the through slot 503 needs to meet the activity requirements of the push rod 703, that is, Figure 1 The transverse dimension of the through slot 503 is at least the difference between the maximum displacement limits of the push rod 703 in the through slot 503 and the diameter of the push rod 703 , and the longitudinal dimension is at least the diameter of the push rod 703 .

[0023] In addition, the second bottom plate 502 is fixedly connected to the vertical plate 505, a positioning cylinder 506 is provided at the center of the second bottom plate 501, the outer side of the positioning cylinder 506 is slidably connected to the planetary gear 4, the positioning cylinder 506 is provided with the guide rod 601, and the rotating rod 701, the sliding rod 702 and the push rod 703 are located between the first bottom plate 501 and the second bottom plate 502 which are arranged in parallel. The outer diameter of the positioning cylinder 506 is consistent with the aperture of the planetary gear 4 to ensure that the planetary gear 4 is limited on the positioning cylinder 506 and can only move in the up and down directions for easy grasping. The second bottom plate 502 is preferably arranged in parallel with the first bottom plate 501.

[0024] In addition, the sliding rod 702 is slidably provided on the top of the first bottom plate 501, and a fixed block 901 is fixedly provided on the top of the first bottom plate 501. The two ends of the horizontally arranged tension spring 902 are respectively connected to the sliding rod 702 and the fixed block 901. The tension spring 902 ensures that the slide cylinder 102 can pull the sliding rod 702 to the original position without squeezing the sliding sleeve 602. At this time, the push rod 703 will not have a strong effect on the clamping plate 504, ensuring the clamping effect of the clamping plate 504 on the planetary gear 4. In an ideal state, when the slide cylinder 102 does not squeeze the sliding sleeve 602, the clamping plate 504 can push the push rod 703, the sliding rod 702, the rotating rod 701 and the sliding sleeve 602 to reset. However, there is friction in the device itself, and the angles set for the clamping plate 504 and the push rod 703 may not be able to meet the requirements of the clamping plate 504 to push the reset of the several.

[0025] In addition, a U-shaped lifting frame 603 is included, and the fixed end of the U-shaped lifting frame 603 vertically penetrates the wire tray 10 and the first bottom plate 501 and is fixedly connected to the bottom of the sleeve 602. When filling the planetary gear 4, the U-shaped lifting frame 603 can be pulled downward to drive the sliding sleeve 602 to slide downward to achieve the opening of the pressing plate 504.

[0026] Furthermore, a plurality of the first bottom plates 501 are evenly arranged on the top of the wire tray 10. That is, there are a plurality of devices for fixing the planetary gears 4 on the wire tray 10, which can meet the operation of the assembly line.

[0027] Working principle: When the planetary gear 4 needs to be filled, the U-shaped lifting frame 603 is pulled downward in sequence to open the pressing plate 504, and the planetary gears 4 are filled in sequence for standby use. When the planetary gear 4 needs to be used, the cylinder 2 pushes the sliding rod 302 outward so that the horizontal distance from the grabbing part 303 to the main frame 101 is slightly larger than the radius of the planetary gear 4. The sliding cylinder 102 of the grabbing device is aligned with the guide rod 601 and moves downward to drive the collar 602 to move downward to drive the push rod 703 to push the clamping plate 504 to expand it. As the grabbing device moves downward, the recessed portion 304 of the grabbing part 303 is flush with the planetary gear 4, and the cylinder 2 contracts inward to make the recessed portion 304 in close contact with the planetary gear 4. At the same time, the clamping block 103 presses the top of the planetary gear 4 under the elastic action of the compression spring 3. The clamping block 103 and the grabbing part 303 jointly fix the planetary gear 4. Thereafter, the grabbing device moves upward to make the planetary gear 4 separate from the second bottom plate 502 and transfer to the process component where the planetary gear 4 needs to be used. At the same time, as the sliding cylinder 102 moves upward, the tension spring 902 will pull the sliding rod 702 back to its original position, and the clamping plate 504 closes inward under the action of the spring 8.

[0028] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
