The output end of the two-claw cylinder is a gripper body. An auxiliary claw is fixedly mounted on the gripper body. Grippers are fixedly mounted on both sides of the bottom of the auxiliary claw. Several sets of annular grooves are formed on the outer wall of the gripper. Soft O-rings are connected to the inner wall of the annular grooves.
[0007] In a preferred embodiment of this utility model, a hollow plate is fixedly installed at the bottom of the two-claw cylinder, and a sliding groove is opened at the bottom of the hollow plate, and the claw extends from the hollow plate to the bottom.

[0010] In a preferred embodiment of this utility model, the soft O-ring may be made of PEEK, nitrile rubber, or urethane.
[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
[0012] Use soft O-rings to clamp the product; depending on the material of the product being clamped, the soft O-ring can be made of PEEK, nitrile rubber, urethane, etc. Using soft materials for the soft O-ring can prevent damage to the product, and the soft O-ring can be quickly replaced after it wears out.
[0013] The external threaded post is installed on the inner wall of the internal threaded hole, and the external threaded post is threadedly connected to the internal threaded hole, which facilitates the replacement of the clamps. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0021] Please refer to Figure 1-4A robotic gripper designed to prevent damage to parts includes a fixed plate 1. A two-jaw cylinder 2 is fixedly mounted at the front end of the fixed plate 1. The output end of the two-jaw cylinder 2 is a gripper body 4. An auxiliary gripper 5 is fixedly mounted on the gripper body 4. Grippers 6 are fixedly mounted on both sides of the bottom of the auxiliary gripper 5. Several sets of annular grooves 62 are formed on the outer wall of the gripper 6. A soft O-ring rubber ring 7 is connected to the inner wall of the annular groove 62. Specifically, the fixed plate 1 has a fixing function for the two-jaw cylinder 2. The two-jaw cylinder 2 and the gripper body 4 form a pneumatic finger, also known as a pneumatic gripper or pneumatic cleaver. It is an actuator that uses compressed air as power to grip or grasp workpieces. The auxiliary grippers 5 are used to fix the grippers 6. The grippers 6 are cylindrical. The annular grooves 62 have a positioning function for the soft O-ring rubber ring 7, which can prevent the product from being crushed.
[0022] The bottom of the two-claw cylinder 2 is fixedly installed with a hollow plate 3, and the bottom of the hollow plate 3 is provided with a sliding groove 31. The claw 4 extends from the hollow plate 3 to the bottom. The top of the claw 4 is fixedly provided with a slider 41, and the slider 41 is slidably connected to the inner wall of the sliding groove 31.
[0023] The attachment claw 5 has internal threaded holes 51 on both sides of its bottom. The top of the gripper 6 is fixedly provided with an external threaded post 61. The external threaded post 61 is installed on the inner wall of the internal threaded hole 51 and is threadedly connected to the internal threaded hole 51, which facilitates the replacement of the gripper 6. The soft O-ring rubber ring 7 is connected to the annular groove 62, which facilitates the replacement of the O-ring rubber ring 7.
[0024] The soft O-ring 7 can be made of PEEK, nitrile rubber, or urethane.
[0025] The working principle of this utility model is as follows: the two-jaw cylinder 2 drives the jaw body 4 to move, the jaw body 4 drives the auxiliary jaw 5 to move, and the auxiliary jaw 5 drives the clamping jaw 6 to move. The product is clamped by a soft O-ring rubber ring 7. The soft O-ring rubber ring 7 can be made of materials such as PEEK, nitrile rubber, and urethane rubber, depending on the material of the product being clamped. The use of a soft material for the soft O-ring rubber ring 7 can prevent damage to the product. The soft O-ring rubber ring 7 can also be quickly replaced after it is worn.
