[0002] Clamping assemblies are very important in industrial manufacturing and processing. They are like the "third hand" in work. Through devices such as fixtures, chucks, and chucks, they ensure that workpieces are firmly fixed during the processing. This firmness not only helps to maintain the correct position and posture of the workpieces, but also greatly improves the processing accuracy and efficiency. In automated production lines and traditional machining, clamping assemblies are not only simple fixing devices, but also key links in process optimization and quality control. For example, through precisely designed fixtures, it can be ensured that every processing step of complex parts can be carried out in the correct position, thereby reducing errors and waste and improving the overall production efficiency.

[0003] The selection and design of clamping assemblies depend on the shape, size of the workpieces and specific processing requirements, so they are widely used in different industries and processes. In short, optimized clamping solutions not only help to ensure product quality, but also effectively support the sustainable development and competitiveness of modern manufacturing.

[0004] In traditional clamping assemblies, although they can replace manual operations, some cannot be effectively clamped due to the special nature of the material and are very easy to fall off the jaws. For example, items packed in cardboard boxes are prone to falling off because the cardboard boxes will be dented, causing damage to the items. Therefore, a clamping assembly with an anti-dropping structure is proposed to solve the above problems. Summary of the Utility Model

[0031] Specifically, the carriage 1 is used to support and connect the clamping assembly. The carriage 1 is an integral gantry that can move freely in the front, back, left, and right directions. The electric push rod 2 is used to drive the clamping assembly to move up and down. The connecting piece 3 is used to connect and support other parts. The air cylinder 4 is used to drive the clamping plate 5 to move left and right. Through the cooperation of the two, clamping is achieved. The limiting rod 6 is used to limit the moving direction of the clamping plate 5 to ensure that the clamping plate 5 can only move left and right and will not move randomly or wobble. The motor 7 is used to drive the worm 8 to rotate. The rotating shaft 9 is used to connect the worm gear 10 and the supporting rod 11. The worm gear 10 is used to mesh with the worm 8 and drive the rotating shaft 9 to rotate. The supporting rod 11 is used to support the bottom of the article to prevent the goods from falling off.

[0032] Referring to Figure 1 - Figure 3 As shown in the figure, the fixing assembly includes a housing 12. The left side of the housing 12 is fixedly connected to the outside of the output end of the electric push rod 2. The inner side wall of the housing 12 is fixedly connected with a sliding rod 13. A spring 14 is sleeved outside the sliding rod 13. The left side of the spring 14 is fixedly connected with a plug rod 15. A pull rod 18 is slidably connected to the upper side inside the housing 12. The bottom of the pull rod 18 is fixedly connected with a baffle 17. A connecting rod 16 is arranged between the baffle 17 and the plug rod 15.

The outer periphery of the baffle 17 is slidably connected to the inner wall of the housing 12. The right side of the spring 14 is fixedly connected to the inner wall of the housing 12. The inside of the plug rod 15 is slidably connected to the outside of the sliding rod 13. The outside of the plug rod 15 penetrates through the left side of the housing 12 and the right side of the output end of the electric push rod 2 and is inserted into the connecting piece 3.

[0033] Specifically, the housing 12 is used to fix and protect the internal parts. The sliding rod 13 is used to control and limit the moving direction of the plug rod 15 to ensure that the plug rod 15 can only move left and right and will not move randomly or wobble. The two ends of the spring 14 are fixed. By compressing the spring 14, it is ensured that the plug rod 15 works normally. The connecting rod 16 is used to compress the spring 14. Under the limitation of the housing 12, the baffle 17 can only move up and down. The pull rod 18 is connected to the top of the baffle 17. When the pull rod 18 is pulled, with the cooperation of all parts, the plug rod 15 will disengage from the connecting piece 3, realizing quick disassembly and assembly.

[0034] Working principle: When using this device, first control the carriage 1 to move the clamping component directly above the item, then control the electric push rod 2 to drive the clamping component to descend. Next, control the cylinder 4 to contract. Under the limitation of the limit rod 6, the clamping plates 5 start to move towards the middle and clamp the item. Then control the electric push rod 2 to drive the clamping component to rise. During the rising process, the motor 7 will start, drive the worm 8 to rotate, and through meshing with the worm gear 10, drive the rotating shaft 9 to rotate, so that the support rod 11 deflects to the inner side of the clamping plate 5 and supports the bottom of the item to prevent the item from falling off. When putting down the item, just control the motor 7 to reverse and the cylinder 4 to extend. When it is necessary to replace the clamping component, first pull the pull rod 18 to drive the baffle 17 to move upwards, make the connecting rod 16 straighten and pull the plug rod 15 into the interior of the housing 12. Then pull out the old clamping component and re-insert the new clamping component. At this time, release the pull rod 18. Under the action of the slide rod 13, the spring 14 pushes the plug rod 15 and pushes the plug rod 15 out and inserts it into the connecting piece 3 to achieve quick disassembly and assembly.
