Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a workpiece 180-degree rotating gripper. Background Technology

[0002] In automated production processes, workpieces often need to be flipped. For example, during parts processing, the front and back sides of the workpiece need to be ground, welded, and painted. In the assembly stage, the workpiece needs to be flipped and precisely connected with other components. The existing workpiece movement and handling methods have at least the following drawbacks: 1. Existing rotary grippers have poor gripping stability. Some grippers use single-jaw or symmetrical jaw structures, which can easily cause workpieces to slip or deform when gripping irregularly shaped workpieces; 2. Existing rotary grippers have a small rotation angle during gripping, which affects the gripping and placement process. Therefore, we have introduced a new 180-degree rotating gripper for workpieces. Utility Model Content

[0003] The main purpose of this utility model is to provide a workpiece 180-degree rotating gripper, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A 180-degree rotating gripper for workpieces includes a main frame structure. An upper clamping mechanism and a lower clamping mechanism are sleeved on the outer surface of the main frame structure and are symmetrically distributed. Two positioning rollers are provided at the front of the upper end of the upper clamping mechanism. A buffer is provided at the right side of the lower end of the main frame structure. A pneumatic motor is provided at the left end of both the upper and lower clamping mechanisms. A drive cylinder is provided at the left end of the main frame structure.

[0005] Preferably, a connecting frame is provided at the upper rear end of both the upper clamping mechanism and the lower clamping mechanism, and a clamping arm is provided at the lower end of both the upper clamping mechanism and the lower clamping mechanism.

[0006] Preferably, the main frame structure includes a support frame, a connecting frame is provided on the upper right side of the support frame, a rotary cylinder structure is fixedly connected to the left end of the connecting frame, a support frame is fixedly connected to the right end of the support frame, a support rod is fixedly connected to the inner frame wall of the support frame, two connecting blocks are fixedly connected to the right end of the connecting frame, and the support frame is fixedly connected to the drive cylinder.

[0007] Preferably, the support rod is sleeved with the connecting frame.

[0008] Preferably, the drive cylinder is sleeved with the support frame.

[0009] Preferably, there are two upper clamping mechanisms, and each of the two upper clamping mechanisms has an upper cylinder at one of its opposite ends.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up an upper clamping mechanism and a lower clamping mechanism, the upper clamping mechanism and the lower clamping mechanism cooperate with each other during the workpiece clamping process, which can clamp workpieces of different sizes, avoid irregular workpieces from falling during the clamping process, and improve stability. 2. The upper and lower clamping mechanisms are supported by the main frame structure. The connecting frame is driven to rotate by the cylinder structure, which in turn drives the upper clamping mechanism to rotate. This allows the workpiece clamped between the upper and lower clamping mechanisms to rotate at multiple angles, facilitating the clamping and placement of the workpiece and improving flexibility.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Please see Figure 1-4 This utility model provides a technical solution: A workpiece 180-degree rotating gripper includes a main frame structure 1. An upper clamping mechanism 3 and a lower clamping mechanism 6 are sleeved on the outer surface of the main frame structure 1, and the upper clamping mechanism 3 and the lower clamping mechanism 6 are symmetrically distributed. Two positioning rollers 2 are provided at the front of the upper end of the upper clamping mechanism 3. A buffer 5 is provided at the right side of the lower end of the main frame structure 1. Pneumatic motors 7 are provided at the left ends of both the upper clamping mechanism 3 and the lower clamping mechanism 6. A drive cylinder 8 is provided at the left end of the main frame structure 1.

[0017] In this embodiment, the main frame structure 1 includes a support frame 11. A connecting frame 14 is provided on the upper right side of the support frame 11. A rotary cylinder structure 12 is fixedly connected to the left end of the connecting frame 14. A support frame 13 is fixedly connected to the right end of the support frame 11. A support rod 16 is fixedly connected to the inner frame wall of the support frame 13. Two connecting blocks 15 are fixedly connected to the right end of the connecting frame 14. The support frame 11 is fixedly connected to the drive cylinder 8. The support rod 16 is sleeved with the connecting frame 14.

[0018] The above scheme supports the upper clamping mechanism 3 and the lower clamping mechanism 6 through the main frame structure 1. The cylinder structure 12 drives the connecting frame 9 to rotate, which in turn drives the upper clamping mechanism 3 to rotate. This allows the workpiece clamped between the upper clamping mechanism 3 and the lower clamping mechanism 6 to rotate at multiple angles, facilitating the clamping and placement of the workpiece and improving flexibility. Both connecting blocks 15 are sleeved with the support rod 16, which can provide limiting support for the height adjustment process of the connecting frame 14.

[0019] In this embodiment, a connecting frame 9 is provided at the upper rear end of both the upper clamping mechanism 3 and the lower clamping mechanism 6, and a clamping arm 10 is provided at the lower end of both the upper clamping mechanism 3 and the lower clamping mechanism 6; the driving cylinder 8 is sleeved with the support frame 11; there are two upper clamping mechanisms 3, and an upper cylinder 4 is provided at the opposite end of each of the two upper clamping mechanisms 3.

[0020] Through the above scheme, during workpiece clamping operations, the upper clamping mechanism 3 can form a lateral clamping constraint on the upper area of ​​the workpiece, while the lower clamping mechanism 6 can achieve a supporting clamping and positioning on the lower area of ​​the workpiece. Through the multi-point clamping action in both directions, the flexibility is improved.

[0021] It should be noted that this utility model is a 180-degree rotating gripper for workpieces. During use, the main frame structure 1 serves as the basic support component of the entire rotating gripper, providing a stable mounting platform for the upper clamping mechanism 3 and the lower clamping mechanism 6. It bears the weight and force from the upper and lower clamping mechanisms and the workpiece being gripped, ensuring that the entire gripper system maintains structural stability during operation and will not deform or shake due to external forces, providing reliable protection for subsequent gripping and rotation operations. Both connecting blocks 15 are sleeved with the support rod 16. This sleeved connection forms a limiting support structure for the height adjustment process of the connecting frame 14. When it is necessary to adjust the height of the connecting frame 14 and its connected components such as the upper clamping mechanism 3, etc. During height adjustment, the connecting block 15 slides up and down along the support rod 16. The support rod 16 provides a track for the sliding of the connecting block 15, restricting its movement to a vertical direction only. This prevents the connecting frame 14 from shifting left or right or wobbling during height adjustment, ensuring the accuracy and stability of the height adjustment. Simultaneously, the friction between the connecting block 15 and the support rod 16, or through a specific locking device, can fix the connecting frame 14 in the appropriate position after adjustment to the desired height, meeting the height requirements of the upper clamping mechanism 3 under different working conditions. The cylinder structure 12 is the core driving component for rotating the upper clamping mechanism 3. The cylinder structure 12 outputs linear motion, driving the connected connecting frame 9 to rotate. Closely connected to the upper clamping mechanism 3, when the connecting frame 9 rotates under the action of the cylinder structure 12, it synchronously drives the upper clamping mechanism 3 to rotate around a specific rotation axis. Since the workpiece is clamped between the upper clamping mechanism 3 and the lower clamping mechanism 6, the rotation of the upper clamping mechanism 3 will drive the workpiece to rotate together, thereby realizing multi-angle rotation of the workpiece within a 180-degree range. This rotation function allows the workpiece to be adjusted to a suitable angle according to actual needs, facilitating clamping and placement operations in different positions, greatly improving the flexibility and applicability of the gripper. During the workpiece clamping process, the upper clamping mechanism 3 and the lower clamping mechanism 6 cooperate with each other to complete the clamping task of workpieces of different sizes. The upper clamping mechanism 3 can... Under the action of a cylinder or other power device, it moves downward in the vertical direction and gradually approaches the workpiece placed on the lower clamping mechanism 6. When the upper clamping mechanism 3 contacts the workpiece, it clamps the workpiece tightly through the friction between the two or a specific clamping structure (such as jaws, clamping plates, etc.). For irregularly shaped workpieces, the design of the upper clamping mechanism 3 and the lower clamping mechanism 6 takes into account the special shape of the workpiece and adopts a multi-point contact or flexible clamping method to ensure that the workpiece is subjected to uniform force during the clamping process and avoids deformation or slippage of the workpiece due to excessive local force. At the same time, by reasonably adjusting the downward pressure and clamping position of the upper clamping mechanism 3, it can adapt to the clamping requirements of workpieces of different sizes and ensure the stability and reliability of clamping.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
