[0014] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0015] Example

[0016] This embodiment proposes a material grabbing mechanical claw for automobile synchronizer production, comprising a base 1, three claw rods 2 and three connecting rods. The base 1 includes three ears 11, and the three ears 11 are distributed at equal angles around the central axis of the base 1. One end of the three claw rods 2 is hingedly connected to the three ears 11 on the base 1, and the other end of the three claw rods 2 is hingedly connected to the connecting plate 3.

[0017] The base 1 is also used to connect to an external driving device, such as connecting an electric hoist through a steel cable or connecting a robotic arm through a flange. There are many options in the prior art, but this solution is limited to improving the mechanical claw structure, so the content related to external connection will not be repeated.

[0018] The connecting plate 3 is provided with a threaded hole 31, which is threadedly connected to the pin 5, and the pin 5 is perpendicular to the connecting plate 3. The connecting plate 3 is used to be placed in the slot 41 of the spline hub 4, and the pin 5 is used to be inserted into the spring hole 42 of the spline hub 4. The spline hub 4 is a prior art part in the synchronizer, and its general structure includes two layers of gear rings, an inner side and an outer side. Three slots 41 for placing sliders are provided at the outer gear ring, and a spring hole 42 is also provided on the bottom surface of the slot 41. In this solution, the three slots 41 and the three spring holes 42 are used to realize the functions of grabbing, transporting, and supporting.

[0019] When in use, the claw rod 2 is manually controlled to open so that the connecting plate 3 enters the slot 41 of the spline hub 4. Then the pin 5 is aligned with the spring hole 42 and inserted into the spring hole 42, and the connecting plate 3 is attached to the bottom surface of the slot 41. Since the top of the claw rod 2 can only rotate and the pin 5 can only move horizontally, when the base 1 is lifted, the posture of the claw rod 2 will be restricted under the gravity of the spline hub 4, thereby achieving the grasping of the spline hub 4, so that subsequent transportation and assembly operations can be achieved. Reinforcing ribs 32 are provided on the outer surface of the connecting plate 3 to increase the strength of the connecting plate 3.

[0020] Example

[0021] This embodiment is improved on the basis of the embodiment 1 in that it also includes three telescopic rods 6. The three telescopic rods 6 are arranged between three adjacent claw rods 2, and the two ends of the telescopic rods 6 are rotatably connected with the relative claw rods 2, and the direction of the rotation axis is perpendicular to the length direction of the corresponding claw rods 2. The purpose of the telescopic rods 6 is to enable the claw rods 2 to open or contract synchronously. When one claw rod 2 is lifted or lowered, the end of the telescopic rod 6 is forced to rotate relative to the claw rod 2, so the other two claw rods 2 will be lifted or lowered synchronously, and the telescopic rods 6 will be extended or shortened during the process. This facilitates the connection plate 3 to quickly align with the three slots 41 on the spline hub 4, thereby improving the working efficiency.
