In other assembly scenarios, the third gear, the fourth gear may also be assembled in the manner described above.
In the present embodiment, the number of the arrangement of the rotary grasping mechanism 20 and the ejector mechanism 30 is plural, for example, the number of the arrangement of the rotary grasping mechanism 20 and the ejector mechanism 30 is three, and each rotary grasping mechanism 20 corresponds to one ejector mechanism 30. The number of the loading slots of the jig 50 is also three. The number of the guide holes 61 is also plural, each four guide holes 61 form a guide hole group, the number of the guide hole groups is three, and each guide hole group corresponds to one loading slot. In operation, the three rotary gripping mechanisms 20 can simultaneously assemble gears on the gear seats 70 carried by the three loading grooves, thereby improving the working efficiency.
In the present embodiment, the rotary grasping mechanism 20 includes a rotary motor 21, a joint 22, and a gripping pipe 23. The rotating electric machine 21 is provided on the mounting plate 11, the tip of the gripping tube 23 is provided on the rotating shaft of the rotating electric machine 21 through the joint 22, and the gripping tube 23 coincides with the axis of the rotating shaft of the rotating electric machine 21, and the joint 22 and the gripping tube 23 are rotated synchronously under the drive of the rotating shaft of the rotating electric machine 21.
Referring to fig. 8, further, a plurality of separation grooves 231 extending along the axial direction of the clamping tube 23 are formed on the tube wall at the bottom end of the clamping tube 23; the tube wall at the bottom end of the clamping tube 23 is separated by a plurality of separation grooves 231 into a plurality of elastic arms 232 for clamping the gear shaft.
In the foregoing solution, the gear is not required to be loaded onto the rotary grabbing mechanism 20 manually or by an additional automated tool, and the rotary grabbing mechanism 20 of this embodiment can automatically grab the gear. The process of grabbing the gear by the rotary grabbing mechanism 20 includes:
the mounting plate 11 drives the rotary grabbing mechanism 20 to move until the bottom end opening of the clamping tube 23 is aligned with the top end of a gear rotating shaft, and then the mounting plate 11 drives the rotary grabbing mechanism 20 to move downwards integrally, wherein the bottom end opening of the clamping tube 23 is contacted with the top end of the gear rotating shaft in the downwards moving process of the clamping tube 23, and the top end of the gear rotating shaft is extruded into the bottom end opening of the clamping tube 23 until the bottom ends of the elastic arms 232 are abutted against the top surface of the gear ring of the gear; each elastic arm 232 is forced to elastically deform outwards, and under the action of deformation elasticity of each elastic arm 232, each elastic arm 232 clamps the top end of the rotating shaft of the gear, so that the process of clamping the gear by the clamping tube 23 is completed. In this scheme, the clamping tube 23 is simple in structure and the clamping process is quick.
After the gear is clamped by the clamping tube 23, when the whole rotary grabbing mechanism 20 moves downwards, the gear can be pressed into the guide hole 61 of the guide plate 60 from top to bottom by the clamping tube 23, and the bottom end of the clamping tube 23 also enters the guide hole 61.

In order to push the gear away from the rotary grasping mechanism 20, the following scheme may be adopted:
the rotary electric machine 21 may be a double-ended motor. The double-ended motor can be understood as: the rotary shaft of the rotary electric machine 21 penetrates the main body of the rotary electric machine 21, and both ends of the rotary shaft are exposed to the outside of the main body of the rotary electric machine 21, respectively. The double-ended motor can be of a common model in the market, and the specific structure and the working principle of the double-ended motor are not limited.
The thimble mechanism 30 comprises a telescopic driving piece 31 arranged on the mounting plate 11 and a thimble 32 arranged at the output end of the telescopic driving piece 31; the bottom end of the thimble 32 penetrates through the rotating shaft of the rotating motor 21 and the connector 22 in turn downwards, and is inserted into the top end of the clamping tube 23, and the telescopic driving piece 31 drives the thimble 32 to move up and down relative to the rotating shaft of the rotating motor 21, the connector 22 and the clamping tube 23. Preferably, the telescopic driving member 31 may be a telescopic cylinder. The telescopic cylinder drives the thimble 32 to move up and down.
The process of the thimble mechanism 30 pushing the gear away from the rotary grabbing mechanism 20 includes:
in the process of moving up the rotary grabbing mechanism 20, the telescopic cylinder drives the thimble 32 to move down, and the tail end of the thimble 32 presses the top end of the rotating shaft of the gear downwards, so that the gear is propped away from the bottom port of the clamping tube 23.
Further, the thimble 32 includes a first section 321 and a second section 322 adjacent to the bottom end of the first section 321; the diameter of second section 322 is smaller than the diameter of first section 321; the bottom end of the second section 322 is inserted into the gripping tube 23. In the scheme, the bending strength of the thimble 32 is higher by increasing the diameter of the first section 321, so that the thimble 32 is prevented from bending in the process of extruding the top end of the rotating shaft of the gear; by reducing the diameter of second section 322, spike 32 may be inserted within gripping tube 23. Through the scheme, the thimble 32 is ensured to have higher bending strength, and the thimble 32 can be inserted into the clamping tube 23.
In other embodiments, the telescoping cylinder may be replaced with a mobile module. The working process of the mobile module is controlled by a control center, and the control center can also control the whole working process of the multi-gear press-fitting device. The control center can control the movable module to drive the thimble 32 to move downwards in real time according to the upward moving displacement of the rotary grabbing mechanism 20, so that the upward moving speed of the rotary grabbing mechanism 20 is ensured to be the same as the downward moving speed of the thimble 32, the lower end of the thimble 32 is always kept at a fixed height, the thimble 32 is always kept to be abutted against the top end of the rotating shaft of the gear at the height position until the top end of the gear is completely separated from the clamping tube 23, and then the movable module drives the thimble 32 to move upwards to restore to the original position. The control center may be a plc controller or a controller commonly used in the automation industry, the displacement of the upward movement of the rotary grabbing mechanism 20 may be measured by using a displacement sensor, and the displacement sensor may be a commercially available sensor, and the installation position and the installation mode of the displacement sensor may be adaptively changed according to different types of sensors, so that the structure, the installation position and the installation mode of the displacement sensor are not described in detail herein.

The elastic member 42 may be a linear spring, a rubber block, a silica gel block, a metal elastic sheet, etc., preferably, the elastic member 42 is a linear spring, and the top end and the bottom end of the linear spring are respectively connected with the limiting plate 111 and the connecting frame 41.
In operation, if the teeth of the second gear 72 are not staggered from the teeth of the first gear 71 during the downward movement of the second gear 72, so that the second gear 72 is forced to stop moving downward when the teeth of the second gear 72 are in contact with the teeth of the first gear 71, the gripping tube 23 is also stopped from moving downward under the blocking of the second gear 72, the gripping tube 23 forces the connector 22, the rotating motor 21 and the connecting frame 41 to stop moving downward, and as the mounting plate 11 continues to move downward, the connecting frame 41 moves relative to the mounting plate 11, i.e., the connecting frame 41 moves upward relative to the mounting plate 11, and at this time the connecting frame 41 and the limiting plate 111 jointly compress the linear spring, which is compressed to form a deforming spring force. When the second gear 72 rotates such that the teeth of the second gear 72 are offset from the teeth of the first gear 71, the second gear 72 continues to move downward relative to the first gear 71, the teeth of the second gear move downward between adjacent teeth of the first gear 71, and the second gear 72 and the first gear 71 mesh. As the second gear 72 continues to move downward relative to the first gear 71, the deformation elastic force of the linear spring can force the connecting frame 41, the rotating motor 21, the connector 22 and the gripping tube 23 to move downward relative to the mounting plate 11, and restore to the original position. In this way, rigid contact between the second gear 72 and the first gear 71 is avoided, reducing the probability of gear damage.
