Description

Technical Field

[0001] This utility model relates to the field of bearing ring production technology, and more specifically, to a high-efficiency material handling gripper for a bearing ring robot. Background Technology

[0002] In the production of bearing rings, the processing equipment needs to load and unload materials. In order to meet the requirements of production speed and output, a robot-assisted vision system is generally used to directly grab two products from the material box at the same time. However, traditional grippers are for one-to-one material handling, which makes it difficult to meet the material handling needs of two workpieces at the same time. Secondly, although the existing two grippers can pick up two workpieces at the same time, they are not suitable for complex material handling situations, such as the uncertainty between the two workpieces or the different models of the two workpieces. In this case, it is difficult to adapt to the material handling needs of two workpieces with just two grippers. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a high-efficiency material handling gripper for a bearing ring robot.

[0004] To achieve the above objectives, this utility model provides a high-efficiency material handling gripper for a bearing ring robot. Its structure includes a base, and its innovation lies in the fact that: one end of the base is provided with a fixed arm, and the other end of the base is provided with a slidable movable arm, the sliding direction of which is closer to or further away from the fixed arm.

[0005] Both the fixed arm and the movable arm are equipped with grippers at their bottoms. Each gripper includes a gripper cylinder and three gripper arms. Each of the three output ends of the gripper cylinder is equipped with an L-shaped fixing block. The three gripper arms are movably connected to the long sides of the three L-shaped fixing blocks. The short sides of the L-shaped fixing blocks surround the center of the gripper cylinder. The movement direction of the gripper arms is closer to or further away from the short sides of the L-shaped fixing blocks.

[0006] Furthermore, the L-shaped fixing block is provided with two fixing holes, and the clamping arm is provided with a strip groove. The strip groove and one of the fixing holes are fixed by a fastening bolt.

[0007] Furthermore, the two ends of the short side of the L-shaped fixing block are provided with inclined surfaces. When the short side of the L-shaped fixing block surrounds the center position of the gripper cylinder, any two adjacent inclined surfaces are parallel to each other.

[0008] Furthermore, the long side of the L-shaped fixing block is provided with a lower serration, and the clamping arm is provided with an upper serration. When the clamping arm and the long side of the L-shaped fixing block are connected, the lower serration and the upper serration mesh with each other.

[0009] Furthermore, the base is provided with a slide rail at its bottom, the slide rail extending towards the fixed arm, and a slider is provided at the top of the movable arm, the slider being slidably mounted on the slide rail.

[0010] The technical effects and advantages of this utility model are as follows: When clamping two workpieces simultaneously, this utility model adjusts the distance between the movable arm and the fixed arm according to the distance between the two workpieces, so that the distance between the two grippers corresponds to the distance between the two workpieces. Then, according to the model of the workpiece, the position of the gripper arm on the long side of the L-shaped fixed block is adjusted synchronously, so that the gripper can be aligned with the center position of the workpiece for clamping. This ensures that the two grippers can clamp two workpieces of different models at the same time, thereby meeting the needs of synchronous clamping and picking of workpieces of different models and improving the efficiency of workpiece clamping.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 3 In one specific embodiment of this utility model, the structure includes a base 1, a fixed arm 11 at one end of the base 1, and a slidable movable arm 12 at the other end of the base 1. The sliding direction of the movable arm 12 is closer to or further away from the fixed arm 11.

[0016] Both the fixed arm 11 and the movable arm 12 are equipped with grippers 2 at their bottoms. Each gripper 2 includes a gripper cylinder 21 and three gripper arms 22. Each of the three output ends of the gripper cylinder 21 is equipped with an L-shaped fixing block 13. The three gripper arms 22 are movably connected to the long sides of the three L-shaped fixing blocks 13. The short sides of the L-shaped fixing blocks 13 surround the center of the gripper cylinder 21. The movement direction of the gripper arms 22 is closer to or further away from the short sides of the L-shaped fixing blocks 13.

[0017] In this invention, when clamping two workpieces simultaneously, the distance between the movable arm 12 and the fixed arm 11 is adjusted according to the distance between the two workpieces so that the distance between the two grippers 2 corresponds to the distance between the two workpieces. Then, according to the model of the workpiece, the position of the clamping arm 22 on the long side of the L-shaped fixed block 13 is adjusted synchronously so that the grippers 2 can be aligned with the center position of the workpiece for clamping. This ensures that the two grippers 2 can clamp two workpieces of different models at the same time, thereby meeting the need for synchronous clamping and picking of workpieces of different models and improving the efficiency of workpiece clamping.

[0018] In this utility model, as a preferred embodiment, the L-shaped fixing block 13 is provided with two fixing holes 3, and the clamping arm 22 is provided with a strip groove 31. The strip groove 31 and one of the fixing holes 3 are fixed by a fastening bolt 32.

[0019] In this utility model, when adjusting the position of the clamping arm 22 on the long side of the L-shaped fixing block 13, a suitable fixing hole 3 is selected, and then the strip groove 31 on the clamping arm 22 is moved. After the position is determined, the elastic groove and the fixing hole 3 are fixed by the fastening bolt 32, thereby realizing the adjustment of the position of the clamping arm 22.

[0020] In this utility model, as a preferred embodiment, the two ends of the short side of the L-shaped fixing block 13 are provided with inclined surfaces 4. When the short side of the L-shaped fixing block 13 surrounds the center position of the gripper cylinder 21, any two adjacent inclined surfaces 4 are parallel to each other.

[0021] In this utility model, when the gripper 2 clamps the workpiece, the gripper cylinder 21 drives the three L-shaped fixing blocks 13 to move synchronously. The inclined surface 4 is designed to prevent the L-shaped fixing blocks 13 from interfering with each other during movement, thus protecting the L-shaped fixing blocks.

[0022] In this utility model, as a preferred embodiment, the long side of the L-shaped fixing block 13 is provided with a lower serration 5, and the clamping arm 22 is provided with an upper serration 5. When the clamping arm 22 and the long side of the L-shaped fixing block 13 are connected, the lower serration 5 and the upper serration 5 mesh with each other.

[0023] In this invention, the upper serration 5 and the lower serration 5 are designed so that the long side of the L-shaped fixing block 13 and the clamping arm 22 can interlock with each other, making the connection between the two reliable and not easy to shift.

[0024] In this utility model, as a preferred embodiment, the bottom of the base 1 is provided with a slide rail 6, the extension direction of the slide rail 6 is towards the fixed arm 11, and the top of the movable arm 12 is provided with a slider 61, which is slidably disposed on the slide rail 6.

[0025] In this invention, the slider 61 and the slide rail 6 are designed to ensure the stability of the movable arm 12 as it moves on the base 1.
