These grippers utilize high-strength materials and optimized structural design, possessing excellent load-bearing capacity to meet the clamping requirements of heavy workpieces.
[0003] However, in the existing technology, the gripper may experience inconsistent finger movements during the gripping process, resulting in insufficient gripping force. At the same time, the existing technology is not convenient to ensure that the gripper moves in a straight line, resulting in poor gripper stability. Utility Model Content
[0004] In order to solve the above problems, the purpose of this utility model is to provide a load-bearing pneumatic gripper with a synchronization mechanism.
[0005] To solve the above technical problems, the present invention adopts the following technical solution: a load-bearing pneumatic gripper with a synchronization mechanism, comprising a base, a fixed frame, and two gripper bodies. The base is fixedly installed on the upper surface of the fixed frame. Cylinders are fixedly installed at both ends of the base. Movable frames are fixedly installed at the piston ends of the two cylinders. A base plate is fixedly installed at one end of each of the two movable frames. The two movable frames and the two base plates are slidably arranged on the fixed frame. A connecting rod can be detachably installed on the lower surface of each of the two base plates. One end of one of the connecting rods is fixedly connected to one side of a gripper body.
[0006] Preferably, a linear guide is fixedly installed in the groove of the fixing frame, and four sliders are slidably installed on the linear guide. The lower surfaces of two adjacent sliders are fixedly connected to the upper surface of a base plate, and the lower surfaces of two adjacent sliders are fixedly connected to the upper surface of another base plate.
[0007] Preferably, two movable rods are slidably installed inside the base, one end of which is fixedly connected to one side of a movable frame, and toothed plates are fixedly installed on opposite sides of both movable rods. A drive shaft is rotatably installed in the middle of the base, and a gear is fixedly installed at one end of the drive shaft. The gear meshes with the two toothed plates.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0009] 1. In this utility model, the transmission and synchronization of motion are achieved through the meshing of gears and racks, ensuring that the movements of multiple gripper bodies are synchronized, thereby accurately controlling the gripping and releasing operations, and also ensuring that the gripping force is always constant. At the same time, the synchronization shaft is integrated with the cylinder, which greatly reduces the number of parts and makes the structure more compact.
[0010] 2. In this utility model, the cooperation of the linear guide and the slider not only ensures that the gripper body moves accurately along the predetermined straight path, but also withstands the bending moment and torque generated as the gripper body moves, thus acting as a reinforcing rib and improving the safety and reliability of the gripper body.

[0018] 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.
[0019] Example: Figure 1-5 As shown, this utility model provides a load-bearing pneumatic gripper with a synchronization mechanism, including a base 1, a fixed frame 2, and two gripper bodies 3. The base 1 is fixedly installed on the upper surface of the fixed frame 2. Anti-slip pads 31 are fixedly installed on opposite sides of the two gripper bodies 3. By setting the anti-slip pads 31, the two gripper bodies 3 can clamp the object through the anti-slip pads 31, thereby improving the stability of the clamped object. Cylinders 4 are fixedly installed at both ends of the base 1. Movable frames 41 are fixedly installed at the piston ends of the two cylinders 4. A base plate 42 is fixedly installed at one end of each of the two movable frames 41. The 41 and two base plates 42 are slidably mounted on the fixed frame 2. The lower surfaces of the two base plates 42 are detachably equipped with connecting rods 43. One end of one of the connecting rods 43 is fixedly connected to one side of a gripper body 3. By setting a cylinder 4, when the piston end of the cylinder 4 contracts and extends, the piston end of the cylinder 4 can move the gripper body 3 horizontally through the movable frame 41, the base plate 42 and the connecting rod 43, so that the two gripper bodies 3 can move closer or further apart. At the same time, by setting the cylinder 4 as a power source, compressed air is used to provide power to realize the actions of grasping, transporting and releasing objects.
[0020] The other ends of the two connecting rods 43 are fixedly connected to connecting parts 44. Two bolts 45 are threadedly connected to each connecting part 44. A number of evenly distributed threaded holes 46 are opened on the two base plates 42. The bolts 45 and the threaded holes 46 are threadedly connected. By setting the bolts 45 and the threaded holes 46, the connecting parts 44 can be fixed to the lower surface of the base plate 42 through the bolts 45 and the threaded holes 46, thereby realizing the installation and disassembly of the gripper body 3.
[0021] A linear guide 5 is fixedly installed in the groove of the fixing frame 2. Four sliders 51 are slidably installed on the linear guide 5. The lower surfaces of two adjacent sliders 51 are fixedly connected to the upper surface of a base plate 42, and the lower surfaces of two adjacent sliders 51 are fixedly connected to the upper surface of another base plate 42. By setting the linear guide 5 and sliders 51, the sliders 51 can slide horizontally on the linear guide 5, thereby ensuring that the gripper body 3 moves accurately along a predetermined straight path. It can also withstand the bending moment and torque generated as the gripper body 3 moves, acting as a reinforcing rib and improving the safety and reliability of the gripper body 3.
[0022] Two sliding rods 6 are slidably installed inside the base 1. One end of one of the sliding rods 6 is fixedly connected to one side of a moving frame 41. Toothed plates 61 are fixedly installed on opposite sides of the two sliding rods 6. A drive shaft 62 is rotatably installed in the middle of the base 1. A gear 63 is fixedly installed at one end of the drive shaft 62. The gear 63 meshes with the two toothed plates 61. By setting the toothed plates 61, drive shaft 62 and gear 63, when the moving frame 41 moves horizontally, the moving frame 41 causes the toothed plates 61 to move horizontally through the sliding rods 6. The horizontal movement of the toothed plates 61 drives the gear 63 to rotate. The gear 63 causes the drive shaft 62 to rotate, realizing the synchronous transmission of power. This allows the movements of multiple gripper bodies 3 to be synchronized, thereby precisely controlling the gripping and releasing operations.
[0023] Working principle: When it is necessary to clamp an object, two cylinders 4 can be activated. The piston ends of the two cylinders 4 can move the two gripper bodies 3 closer to each other or further away from each other through two moving frames 41, two base plates 42 and two connecting rods 43. When they are close to each other, the two gripper bodies 3 clamp the object through two anti-slip pads 31.
[0024] By setting cylinder 4 as a power source and using compressed air to provide power, the actions of grasping, moving and releasing objects are realized;
[0025] Meanwhile, the two movable frames 41 move the two toothed plates 61 away from or close to each other through the two movable rods 6. The two toothed plates 61 drive the gear 63 to rotate, and the gear 63 causes the transmission shaft 62 to rotate, realizing the synchronous transmission of power. This allows the actions of multiple gripper bodies 3 to be synchronized (in the case of multiple load-bearing pneumatic grippers assembled), thereby precisely controlling the gripping and releasing operations.
[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
