[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] like Figure 1-4As shown, an engine valve clamping and transmission device includes a base 1, a transmission mechanism, and a clamping mechanism. The transmission mechanism is fixedly connected to the base 1, and the clamping mechanism is slidably mounted on the transmission mechanism. The transmission mechanism includes two parallel guide rails 2 that pass through the middle. The guide rails 2 are inclined and their bottoms are fixedly mounted on the base 1. Pulleys 13 are rotatably mounted at both ends of the passage between the guide rails 2. A belt 12 is sleeved on the pulleys 13. A servo motor 14 is mounted on the guide rail 2 and is connected to the pulley 13 at one end of the guide rail 2 for transmission.

[0022] The clamping mechanism includes a slide plate 3, a guide rod cylinder 6, a guide rod cylinder 7, and a finger cylinder 8. The guide rod cylinder 6, guide rod cylinder 7, and finger cylinder 8 are all existing technologies, and their structures and principles will not be described in detail here. The bottom center of the slide plate 3 is fixedly connected to the belt 12. The two sides of the bottom of the slide plate 3 are slidably connected to the guide rails 2 on both sides of the belt 12. The top of the slide plate 3 is fixedly connected to the guide rod cylinder 6. The top two sides of the slide plate 3 are provided with fixing blocks 4. The bottom two sides of the guide rod cylinder 6 are provided with fixing blocks 15. The fixing blocks 14 and 15 are coaxially connected by fixing rods 5. The guide rod cylinder 6 is fixedly connected to one side of the slide plate 3 by fixing rods 5.

[0023] The output end of guide rod cylinder 6 is connected to guide rod cylinder 7, and the output end of guide rod cylinder 7 is connected to finger cylinder 8. The direction of action of the output end of guide rod cylinder 6 is perpendicular to the direction of action of the output end of guide rod cylinder 7 on the same horizontal plane, and the direction of action of the output end of finger cylinder 8 is the same as the direction of action of the output end of guide rod cylinder 7.

[0024] The output end of the finger cylinder 8 is provided with two grippers 9. The two grippers 9 are respectively provided with a first gripper 10 and a second gripper 11. The first gripper 10 is located on both sides of the end of one gripper 9, and the second gripper 11 is located in the middle of the end of the other gripper 9. The first gripper 10 and the second gripper 11 are interlocked to better grip the valve 16 rod.

[0025] A control box 17 is installed on the base 1. The control box 17 contains a PLC controller that is electrically connected to the guide rod cylinder 6, the guide rod cylinder 7, the finger cylinder 8, and the servo motor 14.

[0026] The working principle of this utility model:

[0027] After the previous processing step, valve 16 flows out sequentially from the external valve track. The control box 17 controls the servo motor 14 to start, driving the pulley 13 to rotate, thereby moving the belt 12. The belt 12 pulls the slide plate 3 to slide on the track, stopping when it reaches the bottom of the guide rail 2. The guide rod cylinder 7 starts, pushing the finger cylinder 8 forward to the position of valve 16 on the valve track. The finger cylinder 8 starts, driving the two grippers 9 to close and clamp valve 16. The first gripper tooth 10 and the second gripper tooth 11 on the gripper 9 engage with each other to better align the valve 16 rod. The valve 16 is gripped, then the guide rod cylinder 7 is activated, driving the finger cylinder 8 back to its original position. The servo motor 14 is activated, driving the slide plate 3 to move to the top of the guide rail 2. When it reaches the top of the guide rail 2, it stops. The guide rod cylinder 6 is activated, pushing the guide rod cylinder 7 and the finger cylinder 8 to the side to the position of the valve 16 track. The finger cylinder 8 is activated, driving the two grippers 9 to separate. The valve 16 falls onto the valve track and slides into the next process. The guide rod cylinder 6 is activated, driving the guide rod cylinder 7 and the finger cylinder 8 back to their original positions, completing the single valve 16 gripping and transfer operation.
