[0002] A hydraulic cylinder is a device that uses the hydraulic principle to generate linear motion. It usually consists of a piston and a matching cylinder. The pressure of the hydraulic oil drives the piston to generate linear motion inside the cylinder, thereby realizing the lifting, pushing, pulling, clamping and other functions of various engineering machinery, industrial equipment or vehicles. The hydraulic cylinder is a precision mechanical part, and high precision and surface quality need to be maintained during the processing. Excessive temperature will cause the surface hardness of the workpiece to decrease, deformation and residual stress to increase, affecting the processing quality. Controlling the processing temperature through a cooling device can improve the processing accuracy and surface quality, and ensure the processing quality of the hydraulic cylinder.

[0003] When an existing hydraulic cylinder cooling device is in use, a sealing pad and a sealing plate are provided to keep the sealing plate and the fixing plate sealed, so that cold air can quickly cool the hydraulic cylinder body, thereby increasing the cooling rate of the hydraulic cylinder and making the hydraulic cylinder cooler more comprehensively.

The unfixed hydraulic cylinder may move or tilt during the cooling process, increasing the risk of injury to the operator.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The hydraulic cylinder body 12 is placed on the upper part of the support frame 1. The support frame 1 is firm and stable, and can ensure that the hydraulic cylinder body 12 maintains a stable position and posture in subsequent operations. The hydraulic cylinder 2 is started, and its output end begins to push the fixed block 3 to move. The fixed block 3 is linked with the slider 10 to make the slider 10 slide smoothly on the outside of the slide rod 11. When the slider 10 is driven to move by the fixed block 3, it further drives the moving rod 8 to move. In this process, the moving rod 8 stretches the spring 9. The spring 9 has good elasticity and restoring force, and can provide necessary resistance and support when the moving rod 8 moves. The spring 9 provides necessary guidance and stabilization when the moving rod 8 slides inside the fixed rod 7. As the fixed block 3 moves, the connecting rod 4 is also driven, and then the clamping piece 5 is driven closer. The clamping piece 5 can be driven by the connecting rod 4 to fit tightly on the surface of the hydraulic cylinder body 12 to fix the hydraulic cylinder body 12.

[0028] Reference Figure 1 , Figure 2 and Figure 4 A placement plate 22 is fixedly connected to the inside of the support frame 1, a fan 14 is fixedly connected to the upper part of the placement plate 22, a delivery hose 15 is fixedly connected to the output end of the fan 14, the other end of the delivery hose 15 is fixedly connected to a fixed pipe 18, and an air outlet hood 19 is provided at the bottom of the fixed pipe 18, a water tank 13 is fixedly connected to the upper part of the placement plate 22, a condenser 16 is provided inside the water tank 13, a water inlet pipe 21 is fixedly connected to the upper part of the water tank 13, a water outlet pipe 20 is fixedly connected to the front part of the water tank 13, the delivery hose 15 is inserted into the inside of the water tank 13, a fixed frame 17 is fixedly connected to the upper part of the support frame 1, and the fixed pipe 18 is fixedly connected to the inside of the fixed frame 17.

[0029] The fan 14 starts to work and performs exhaust operation. The wind is transported through the delivery hose 15. In this process, water is added to the inside of the water tank 13 through the water inlet pipe 21. The water in the water tank 13 is cooled under the action of the condenser 16. In this process, the temperature of the water will be significantly reduced. The cold water cools the water inside the delivery hose 15. The temperature of the water inside the delivery hose 15 will drop, achieving a cooling effect. The cooled wind is transported to the fixed pipe 18 through the delivery hose 15 and finally reaches the air outlet hood 19. The design of the air outlet hood 19 allows the cold wind to be evenly sprayed on the surface of the hydraulic cylinder body 12, effectively reducing its temperature.

[0030] Working principle: First, place the hydraulic cylinder body 12 on the upper part of the support frame 1, start the hydraulic cylinder 2, and the output ends of the two hydraulic cylinders 2 push the fixed block 3 to move. When the fixed block 3 moves, it drives the slider 10 to slide on the outside of the slide rod 11. Under the action of the slider 10, the two fixed blocks 3 move. When the fixed block 3 moves, it drives the moving rod 8 to move. When the moving rod 8 moves, the spring 9 is stretched. Under the action of the spring 9, the moving rod 8 slides inside the fixed rod 7, so that the two fixed blocks 3 drive the connecting rod 4 to move, and the connecting rod 4 drives the clamping piece 5 to get closer to fix the hydraulic cylinder body 12, so that the hydraulic cylinder body 12 can be effectively clamped and fixed, which can ensure that the stable position and posture are maintained during the cooling process to avoid affecting the cooling effect due to movement or swinging. The effect is to improve the stability and efficiency of cooling. When in use, the fan 14 is started, and the fan 14 is exhausted to transport the wind through the delivery hose 15. When the wind is being transported, water is added to the inside of the water tank 13 through the water inlet pipe 21, and the water is cooled by the condenser 16. Then, the air inside the delivery hose 15 is cooled by the cold water inside the water tank 13. The cooled wind is transported to the fixed pipe 18 through the delivery hose 15, and then transported to the air outlet hood 19 through the fixed pipe 18. The cold wind is sprayed on the surface of the hydraulic cylinder body 12 through the air outlet hood 19 to cool the hydraulic cylinder body 12, thereby realizing that the temperature of the hydraulic cylinder body 12 can be quickly reduced, the failure and damage of the system can be reduced, the repair and replacement costs can be reduced, and the maintenance cost of the system can be reduced.
