Description

Technical Field

[0001] This utility model relates to the field of gripping mechanisms, and more specifically, to a rotary gripping mechanism that reduces the rotation of air tubes and cables. Background Technology

[0002] To improve production efficiency, manufacturers often use automated equipment. Among these automated equipment, the gripping mechanism that automatically grabs and transports materials is one of the most important components.

[0003] Existing rotary gripping mechanisms use pneumatic cylinder grippers to grasp materials. A drive cylinder is connected to the pneumatic cylinder gripper, thereby driving the pneumatic cylinder gripper to move. At the same time, the rotary gripping mechanism rotates the pneumatic cylinder gripper and the drive cylinder to grasp materials or place materials in different positions. However, both the pneumatic cylinder gripper and the drive cylinder need to be connected to air pipes and sensor cables. The air pipes and sensor cables need to rotate with the pneumatic cylinder gripper and the drive cylinder, making the routing of air pipes and sensor cables difficult. Furthermore, during the rotation process, the air pipes and sensor cables are prone to getting tangled or even breaking, increasing the equipment failure rate. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, a rotary gripping mechanism that reduces the rotation of air tubes and cables is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rotating gripping mechanism to reduce the rotation of air pipes and cables, including a mounting plate, a rotating platform rotatably mounted on the mounting plate, a driving device for driving the rotating platform to rotate on the mounting plate, one or more grippers slidably mounted longitudinally on the rotating platform, a push block mounted on the gripper, a plurality of driving cylinders for pushing the push block mounted on the mounting plate, the plurality of driving cylinders being arranged at equal intervals around the rotating platform, and a reset mechanism for sliding reset of the gripper on the rotating platform.

[0006] Preferably, a connecting plate is provided on the surface of the rotary table away from the mounting plate, a linear guide rail extending vertically is provided on the connecting plate, a slider is slidably mounted on the linear guide rail, a mounting frame is provided on the slider, the gripper is mounted on the mounting frame, and the push block is also mounted on the mounting frame.

[0007] Preferably, the reset mechanism includes a stop block and a reset spring. The stop block is disposed at one end of the connecting plate away from the rotary table, and the reset spring is disposed between the stop block and the mounting bracket.

[0008] Preferably, the mounting bracket is provided with a clearance groove for the clearance block, the bottom of the clearance groove is provided with a guide post groove, the clearance block is provided with a guide post that is inserted into the guide post groove, and the reset spring is sleeved on the guide post.

[0009] Preferably, the gripper is provided in multiple manner, and the multiple grippers are arranged at equal intervals along the circumference of the rotary table, and the push blocks on the multiple grippers are located at positions directly opposite to the output shaft of the corresponding drive cylinder.

[0010] Preferably, the driving device is a hollow rotating platform, the mounting plate is provided with a mounting through hole, the hollow rotating platform is installed in the mounting through hole, and the rotating table is set on the hollow rotating platform.

[0011] Preferably, a rubber block is provided on the output shaft of the drive cylinder.

[0012] The beneficial effects of this utility model are as follows: the driving device drives the rotary table to rotate, thereby driving the gripper to rotate. When the push block rotates to the position directly opposite the output shaft of any driving cylinder, the driving device stops rotating the rotary table. The output shaft of the driving cylinder extends, thereby driving the gripper to move downward. After the gripper picks up or puts down the material, the output shaft of the driving cylinder retracts. The gripper moves upward to reset under the action of the reset mechanism. The driving cylinder does not rotate with the gripper, reducing the number of rotating air pipes and cables, thus making it less likely for the air pipes and sensor cables to be tangled and reducing the equipment failure rate.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. In addition, the directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying drawings. The directional terms are used to better and more clearly explain and understand this utility model, and are not intended to indicate or imply the necessary orientation of this utility model. Therefore, they should not be construed as limitations on this utility model.

[0018] Examples of embodiments of this utility model Figures 1 to 3 As shown, a rotary gripping mechanism for reducing the rotation of air tubes and cables includes a mounting plate 1. A rotating platform 2 is rotatably mounted on the mounting plate 1, located on the bottom surface of the mounting plate 1. A drive device 7 for driving the rotating platform 2 to rotate is also provided on the mounting plate 1. One or more grippers 4 are longitudinally slidably mounted on the rotating platform 2, located on the bottom surface of the rotating platform 2. Push blocks 40 are provided on the grippers 4. Multiple drive cylinders 5 for pushing the push blocks 40 are provided on the mounting plate 1. Preferably, four drive cylinders 5 are provided, and the four drive cylinders 5 are arranged at equal intervals around the rotating platform 2. At this time, the output shaft of the drive cylinder 5 faces downward. When there is one gripper 4, the gripper 4 is located at the center of the bottom surface of the rotary table 2. The push block 40 is located at the position directly opposite to the output shaft of any drive cylinder 5. When there are multiple grippers 4, preferably four grippers 4 are provided. The four grippers 4 are arranged at equal intervals along the circumference of the rotary table. The push blocks 40 on the four grippers 4 are located at the position directly opposite to the output shaft of the corresponding drive cylinder 5, that is, the four push blocks 40 are located directly below the output shaft of the four drive cylinders 5. The rotary table 2 is provided with a reset mechanism 6 for sliding reset of the grippers 4.

[0019] The drive device 7 drives the rotary table 2 to rotate, thereby driving the gripper 4 to rotate. When the push block 40 rotates to the position directly opposite the output shaft of the corresponding drive cylinder 5, the drive device 7 stops rotating the rotary table 2. The output shaft of the drive cylinder 5 extends, thereby driving the corresponding gripper 4 to move downward. After the gripper 4 grips or releases the material, the output shaft of the drive cylinder 5 retracts, and the gripper 4 moves upward to reset under the action of the reset mechanism 6. The drive cylinder 5 does not rotate with the gripper 4, reducing the number of rotating air pipes and sensor cables, thus making it less likely for the air pipes and sensor cables to be tangled and reducing the equipment failure rate. At the same time, the four grippers 4 of this rotating gripping mechanism can move up and down synchronously or separately, which can grip materials more flexibly.

[0020] Further improvements, such as Figure 1 and Figure 2 As shown, a connecting plate 3 is provided on the surface of the rotary table 2 away from the mounting plate 1. Four connecting plates 3 are also vertically arranged, and the four connecting plates 3 are evenly spaced along the circumferential edge of the rotary table 2. A linear guide rail 30 extending vertically is provided on the connecting plate 3. Preferably, the linear guide rail 30 is a grooved linear guide rail. A slider 31 is slidably mounted on the linear guide rail 30. A mounting frame 32 is provided on the slider 31. The gripper 4 is mounted on the mounting frame 32 and is located at the bottom end of the mounting frame 32. The push block 40 is also mounted on the mounting frame 32. The vertical movement of the gripper 4 is guided by the linear guide rail 30 and the slider 31, making the movement of the gripper 4 more stable.

[0021] Further improvements, such as Figure 1 and Figure 2 As shown, the reset mechanism 6 includes a stop block 60 and a reset spring 61. The stop block 60 is a cuboid structure and is located on the connecting plate 3 at one end away from the rotary table 2. The stop block 60 is located at the bottom of the rotary table 2. Preferably, the stop block 60 is integrally formed with the connecting plate 3. The reset spring 61 is located between the stop block 60 and the mounting bracket 32. Preferably, one end of the reset spring 61 is connected to the stop block 60 and the other end of the reset spring 61 is connected to the mounting bracket 32. After the output shaft of the drive cylinder 5 retracts, the gripper 4 moves upward and resets through the reset spring 61.

[0022] Further improvements, such as Figure 2 and Figure 3As shown, the mounting frame 32 is provided with a clearance groove 320 for the clearance block 60. The mounting frame 32 is a rectangular plate structure, vertically arranged, with the clearance groove 320 located at the middle of the bottom end of the mounting frame 32. The end of the clearance block 60 away from the connecting plate 3 slides relative to the clearance groove 320. Mounting blocks are provided on both sides of the mounting frame 32 near the bottom end. The mounting blocks are integrally formed with the mounting frame 32, forming a "U"-shaped structure. The top surface of the mounting block is provided with a mounting through hole. The gripper 4 passes through the mounting block and the mounting plate 60. A through hole is provided on the mounting bracket 32. The push block 40 is located on the surface of the mounting bracket 32 ​​away from the slider 31. The push block 40 is also located above the corresponding clearance groove 320. The bottom of the clearance groove 320 is provided with a guide post groove 8. The stop block 60 is provided with a guide post 80 that is inserted into the guide post groove 8. The guide post 80 is provided on the top surface of the stop block 60. The return spring 61 is sleeved on the guide post 80. The guide post 80 and the guide post groove 8 prevent the return spring 61 from bending when compressed, thereby extending the life of the return spring 61 and ensuring the stability of the return spring 61.

[0023] Further improvements, such as Figure 1 and Figure 2 As shown, the driving device 7 is a hollow rotating platform. The mounting plate 1 is provided with a mounting through hole. The hollow rotating platform is installed in the mounting through hole. The motor of the hollow rotating platform is located on one side of the top surface of the mounting plate 1. The rotating table is set on the hollow rotating platform. The hollow rotating platform has high rotation accuracy and high repeatability positioning accuracy, which improves the accuracy of this rotating gripping mechanism when gripping materials.

[0024] Further improvements, such as Figure 1 and Figure 2 As shown, a rubber block 9 is provided on the output shaft of the drive cylinder 5. The rubber block 9 reduces the noise generated by the collision between the output shaft of the drive cylinder 5 and the push block 40 when the drive cylinder 5 drives the gripper 4 to move downward, and can also extend the life of the output shaft of the drive cylinder 5.
