The gripper frame body 4b is connected to the main shaft 4a, and the main shaft 4a is rotatably mounted on the upper end of the swing arm 2.

[0021] More specifically, the main body 4b of the gripper frame includes a T-shaped frame 43 and a base 44. The T-shaped frame 43 is horizontally arranged and includes a crossbeam 431 and a connecting beam 432. One end of the connecting beam 432 is connected to the back of the crossbeam 431, and the other end of the connecting beam 432 is connected to the base 44. The base 44 has a pair of downwardly extending lugs 442. The main shaft 4a passes through the pair of lugs 442 and is connected to the pair of lugs 442. The connection method includes, but is not limited to, key connection. The swing arm 2 has a hollow swing arm housing 2a. The upper end of the swing arm housing 2a is provided with a pair of forked portions 21. The two ends of the main shaft 4a are rotatably mounted on the pair of forked portions 21 through bearings 46.

[0022] A pair of pneumatic grippers 5 are linearly slidable on the gripper frame 4. A pneumatic gripper spacing adjustment mechanism is provided on the gripper frame 4 to drive the pair of pneumatic grippers 5 to move towards or away from each other, thereby reducing or increasing the spacing between the pair of pneumatic grippers 5.

[0023] In this embodiment, a pair of guide rails 45 are provided on the crossbeam 431 of the gripper frame 4, and a slider 55 that slides with the pair of guide rails 45 is provided on the back of each pneumatic gripper 5. The pneumatic gripper spacing adjustment mechanism includes a first cylinder 61 and a second cylinder 62. The first cylinder 61 and the second cylinder 62 are respectively fixed to the crossbeam 431 of the gripper frame 4. The first cylinder 61 is connected to one of the pneumatic grippers 5, and the second cylinder 62 is connected to the other pneumatic gripper 5.

[0024] Furthermore, the crossbeam 431 of the gripper frame 4 is provided with a pair of first limiting blocks 461 and a pair of second limiting blocks 462. The pair of first limiting blocks 461 are respectively located on both sides of one of the pneumatic grippers 5 to limit the movement range of the one pneumatic gripper 5. The pair of second limiting blocks 462 are respectively located on both sides of the other pneumatic gripper 5 to limit the movement range of the other pneumatic gripper 5.

[0025] The upper end of the buffer component 7 is hinged to the vertical rod 12 of the support 1, and the lower end of the buffer component 7 is hinged to the middle of the swing arm 2. The middle portion here refers to the midpoint between the two ends of the swing arm 2, including but not limited to the midpoint of the swing arm housing 2a. In this embodiment, the buffer component 7 is a swing arm cylinder, which includes a cylinder barrel 71 and a push rod 72. The cylinder barrel 71 is hinged to the vertical rod 12 of the support 1, and the push rod 72 is hinged to the middle of the swing arm 2.

[0026] Furthermore, the dual-position swing arm gripper includes a gripper frame rotation damping mechanism, which increases rotational resistance when the gripper frame 4 rotates relative to the swing arm 2. In this embodiment, the gripper frame rotation damping mechanism includes a drive sprocket 81, a driven sprocket 82, a driven sprocket frame 83, a driven sprocket shaft 84, and a chain 85. The drive sprocket 81 is mounted on the main shaft 4a and rotates synchronously with the main shaft 4a. The driven sprocket shaft 84 is rotatably mounted on the driven sprocket frame 83. The chain 85 is housed within the swing arm housing 2a and winds around the drive sprocket 81 and the driven sprocket 82.

[0027] In some specific embodiments, the aforementioned pneumatic gripper 5 is a pneumatic spring gripper used to grip the spring 9.

[0028] The working process of the dual-station swing arm gripper in this embodiment of the utility model is as follows.

[0029] After a pair of pneumatic grippers 5 grasp a part, motor 31 drives swing arm 2 to swing. The push rod 72 of the swing arm cylinder first retracts and then extends. Swing arm 2 moves from the left side of the vertical rod 12 of bracket 1 (e.g., Figure 1 (As shown) swing to the right side of the vertical rod 12 of the support 1 (as shown) Figure 6 (As shown). When the swing arm 2 swings, the main shaft 4a of the gripper frame 4 rotates relative to the swing arm 2, thereby driving the driving sprocket 81 and the driven sprocket 82 to rotate in sequence. The damping effect of the sprocket mechanism can prevent the gripper frame 4 from rotating, thus ensuring that the gripper frame 4 moves smoothly from the left side of the vertical rod 12 to the right side of the vertical rod 12, realizing the smooth handling of parts. After the pair of pneumatic grippers 5 are released, the gripped parts are transferred to the equipment of the next process. The distance between the pair of pneumatic grippers 5 can be adjusted by the pneumatic gripper spacing adjustment mechanism to meet different parts gripping scenarios.

[0030] The dual-station swing arm gripper of this utility model can replace manual handling of parts, and is equipped with two sets of pneumatic grippers to realize dual-station handling, which has high handling efficiency.

However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can extend and deduce it according to actual use without departing from the content of the present invention. Therefore, the content of the above specific embodiments should not limit the scope of protection defined by the present invention.
