[0022] The present invention is described in detail below in conjunction with specific embodiments.

[0023] In the present utility model, unless otherwise clearly specified and limited, when terms such as "set on", "connected", and "connected" appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through one or more intermediate media. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The directional words that appear in the present utility model are to better illustrate the characteristics of the features and the relationship between the features. It should be understood that when the placement direction of the present utility model changes, the characteristics of the features and the direction of the relationship between the features also change accordingly. Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0024] like Figures 1 to 8 As shown, the utility model provides a chuck for a steering wheel clamping robot, including a bracket 1, with clamping assemblies 2 arranged on both sides of the bracket 1, the clamping assembly 2 including a clamping drive 21 and a movable claw 22, the clamping drive 21 is installed on the bracket 1, and two movable claws 22 are arranged on each clamping drive 21, and the clamping drive 21 is used to drive the movable claws 22 to move closer to or away from each other; each movable claw 22 is provided with a pad 23, and a groove 24 fitting with the steering wheel frame is arranged on the pad 23.

[0025] Through the above design scheme, when it is necessary to clamp the steering wheel for transfer, the robot controls the bracket 1 to reach the predetermined position, and the clamping drive 21 controls the movable claws 22 to approach each other to clamp the steering wheel. Under the action of the groove 24, the steering wheel can be firmly clamped, which reduces the force required for clamping and avoids slipping when clamping the steering wheel, affecting the clamping accuracy.

[0026] In this embodiment, since there is a set of clamping components 2 on both sides of the bracket 1, two steering wheels can be clamped at the same time during operation, which effectively improves the processing efficiency.

[0027] In this embodiment, a positioning assembly 3 is provided on the bracket 1, and the positioning assembly 3 includes a sleeve 31, a positioning probe 32 and a reset elastic member 35. The sleeve 31 is fixedly mounted on the bracket 1, and the positioning probe 32 can slide in the sleeve 31. The reset elastic member 35 is installed in the sleeve 31, and one end of the reset elastic member 35 abuts against the positioning probe 32, and the other end abuts against the bracket 1.

[0028] In this embodiment, a position sensor 33 is provided on the bracket 1 near the sliding sleeve 31 , and a protrusion 34 is installed on the positioning probe 32 .

[0029] Through the above design scheme, when the positioning probe 32 is retracted against the steering wheel, the protrusion 34 will gradually approach the in-place sensor 33. When the in-place sensor 33 detects the protrusion 34, it indicates that the groove 24 is just aligned with the side position of the steering wheel. At this time, the movable claw 22 gradually approaches to clamp the steering wheel in the groove 24.

[0030] In this embodiment, a limit block 4 is installed on the clamping drive member 21, and the limit block 4 can be used to limit the position of the steering wheel to prevent the groove 24 from being offset during clamping and affecting the clamping accuracy.

[0031] In this embodiment, a connection portion for connecting to a robot is provided on the bracket 1 .

[0032] In this embodiment, a soft rubber layer is provided at the groove 24. The soft rubber layer is made of high-temperature resistant rubber. The soft rubber layer can prevent the steering wheel from being damaged during clamping.

[0033] Compared with the prior art, the chuck for a steering wheel clamping robot provided by the utility model has the following characteristics: when clamping the steering wheel, the positioning probe 32 is aligned with the central hole of the steering wheel, and when the in-position sensor 33 detects that the protrusion 34 is approaching, the groove 24 can just be aligned with the steering wheel at this moment; under the drive of the clamping drive member 21, the movable claws 22 approach each other to clamp the steering wheel, and when the clamping is at a suitable position, the movable claws 22 are released, and the steering wheel will be ejected to the next process under the action of the reset elastic member 35.

[0034] In the absence of conflict, the above-mentioned embodiments and features thereof may be combined with each other.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
