Description

Technical Field

[0001] This utility model relates to a cylinder, specifically a water-cooled cylinder. Background Technology

[0002] A cylinder is a pneumatic actuator that uses compressed air to drive a piston in linear reciprocating motion. Widely used in automated equipment and industrial production lines, its core function is to convert gas pressure into mechanical force, enabling precise and rapid pushing and pulling actions. Its applications cover core manufacturing processes: in automotive assembly lines, cylinders are used for body welding and component pressing; in food packaging machinery, they drive grippers for sorting and sealing; the electronics industry relies on miniature cylinders for chip mounting and precision testing; and in logistics and warehousing, cylinders assist sorting mechanisms in high-speed operation, working with conveyor belts to classify goods and ensure production safety and efficiency. With its simple structure, convenient maintenance, and rapid response, the cylinder has become an indispensable power module in modern industry, especially in scenarios requiring high-frequency repetitive actions, significantly improving production line reliability and capacity.

[0003] In the prior art, patent number 202320726707.5 describes a low-energy-consumption water-cooled cylinder, relating to the field of cylinder technology. It includes a cylinder body with a protective ring at both the top and bottom, connected by a connecting rod. The cylinder body has a cylindrical, hollow shell on its exterior, with the top and bottom of the shell's inner wall respectively and correspondingly fixedly connected to the pair of protective rings. A water storage bag filled with cooling water is located inside the shell. An inlet pipe is located on the lower part of one side of the water storage bag, and an outlet pipe is located on the upper part of the other side. Cooling water enters the water storage bag through the inlet pipe and exits through the outlet pipe. This invention utilizes a water storage bag within the shell, injecting cooling water into it to cause the bag to expand and adhere to the outer wall of the cylinder body. This allows for the circulating, flowing cooling water to dissipate heat and cool the cylinder body, preventing premature damage to the sealing rings inside the cylinder and ensuring the cylinder body remains in a reliable working state.

[0004] Although existing water-cooled cylinders can cool the cylinder by injecting cooling water into a water storage bag, causing the water storage bag to expand and fit against the outer wall of the cylinder, thereby dissipating heat and cooling the cylinder through circulating and flowing cooling water, such water storage bags are easily damaged and not robust enough. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies where water storage bags are easily damaged, this utility model provides a water-cooled cylinder.

[0006] This utility model is achieved using the following technical solution: a water-cooled cylinder, comprising a cylinder, a working space within the cylinder, a piston rod within the working space, a sealed piston fitted onto the piston rod, an assembly connection component at the top of the piston rod, the assembly connection component being a connecting end, the connecting end having a connecting circular hole, an air inlet port on the cylinder, the air inlet port being divided into a front air inlet port and a rear air inlet port, a water-cooling component within the cylinder, the water-cooling component being a water-cooling pipe, the water-cooling pipe having a circular structure, the circular water-cooling pipe being evenly distributed on the inner wall of the cylinder.

[0007] The water-cooled pipes are symmetrically distributed on the inner wall of the cylinder, and the heat of the inner wall of the cylinder is transferred to the water-cooled pipes. Connecting pipes are provided between the water-cooled pipes.

[0008] The water-cooled pipes and connecting pipes are interconnected. The water-cooled pipes are provided with inlet ports and outlet ports, and water pipe assembly ends are provided on the inlet ports and outlet ports.

[0009] The water pipe assembly pipe is equipped with clamps, the clamps are equipped with fixing screws, and the inner wall of the clamps is equipped with sealing rubber rings for sealing.

[0010] The cylinder is provided with an end cover on one side, and a bottom mounting valve block is provided on the end cover. The bottom mounting valve block is provided with a bottom mounting round hole.

[0011] Compared to existing technologies, this water-cooled cylinder achieves efficient heat exchange through the layout of circular water-cooling pipes. The water-cooling pipes are symmetrically and evenly attached to the inner wall of the cylinder, forming a full-coverage cooling network that can quickly absorb the heat generated by the piston rod. The connecting pipes run through each water-cooling unit, forming a closed-loop cooling circuit, ensuring smooth coolant circulation, effectively balancing the temperature field inside the cylinder. The circular pipes have a larger contact area with the cylinder wall, significantly improving heat conduction efficiency, which can extend the life of the cylinder assembly and reduce energy loss due to overheating.

[0012] The synergistic structure of clamps, fixing screws, and sealing rings makes the assembly of water pipes safer. The clamps, together with the screws, allow for precise adjustment of tightness, adapting to different pipe diameters and vibration environments, avoiding the problem of loosening that is common in traditional threaded connections. The sealing rings are embedded in the inner wall of the clamps, making the assembly of water pipes and inlet / outlet ports tighter. The end caps are equipped with bottom mounting valve blocks, which allow for better assembly and fixation of the water-cooled cylinder and positioning components. Attached Figure Description

[0020] The water-cooled cylinder achieves efficient heat exchange through the layout of circular water-cooling pipes. The water-cooling pipes 8 are symmetrically and evenly attached to the inner wall of the cylinder to form a full-coverage cooling network, which can quickly absorb the heat generated by the piston rod. The connecting pipes 9 run through each water-cooling unit to form a closed-loop cooling circuit, ensuring smooth circulation of coolant and effectively balancing the temperature field inside the cylinder.

The clamp 10, together with the screw, allows for precise adjustment of tightness, adapting to different pipe diameters and vibration environments, avoiding the problem of loosening in traditional threaded connections. The sealing ring 11 is embedded in the inner wall of the clamp, making the assembly of the water pipe and the inlet / outlet ports tighter.
