[0025] See also Figure 1-3 A high-precision guide sleeve for hydraulic accessories, comprising a cylinder 1 and a reinforcement component. The reinforcement components are arranged at both ends and near the middle of the cylinder 1. Two groups of clamping grooves 2 are opened inside the cylinder 1. A connecting layer 3 is fixedly connected to the outside of the cylinder 1. A coating 5 is arranged outside the connecting layer 3.

[0026] It should be noted that the engaging groove 2 can cooperate with a frame or other structures to maintain the position of the guide sleeve through insertion and fixation.

[0027] The reinforcing assembly includes reinforcing ribs 4 and fixing grooves 6. The reinforcing ribs 4 are fixedly connected to the outside of both ends of the connecting layer 3. There are two groups of fixing grooves 6, which are both opened outside the cylinder 1 and symmetrically distributed along the horizontal center line of the cylinder 1.

[0028] In this embodiment, the cylinder 1 is made of alloy steel, and the two groups of clamping grooves 2 are symmetrically distributed along the horizontal center line of the cylinder 1 and chamfers are arranged at the corners.

[0029] It should be noted that alloy steel has high tensile strength and yield point, and can withstand greater pressure and load. Using this material to make the cylinder 1 can effectively ensure the strength of the guide sleeve. At the same time, the smooth interior of the cylinder 1 is to guide the flow of fluid, reduce the resistance of fluid flow, improve the fluidity of the fluid, and ensure the accuracy and stability of the hydraulic action.

[0030] In this embodiment, the two groups of fixing grooves 6 extend through the cylinder 1 to the middle of the two groups of clamping grooves 2. The inner walls of the two groups of fixing grooves 6 are both provided with thread grooves, and each group of fixing grooves 6 has four thread grooves distributed around the circumference.

[0031] It should be noted that after the clamping groove 2 is initially fixed with the frame or other structures, the fixing groove 6 is threadedly connected with the screw to firmly fix the cylinder body 1.

[0032] In this embodiment, the cylinder 1 and the connection layer 3 are both streamlined near both ends, and the connection layer and the reinforcing ribs 4 are made of carbon fiber reinforced plastic.

[0033] It should be noted that the cylinder 1 and the connection layer 3 are both streamlined near both ends, so that they present a shape that is more in line with fluid dynamics, so as to reduce the impact and vortex generation of the fluid when entering and exiting. This design can reduce the flow resistance of the fluid inside the guide sleeve, making the fluid flow more smoothly and improving the working efficiency of the hydraulic cylinder.

[0034] In this embodiment, the connection layer 3 and the reinforcing rib 4 are fixedly connected by thermal assembly, and a sealant is coated at the connection between the connection layer 3 and the reinforcing rib 4 .

[0035] It should be noted that, by utilizing the thermal assembly method, the reinforcing rib 4 or the guide sleeve is heated to increase its plasticity so that they can be assembled together better, and at the same time, a sealant is applied to the connection to improve the sealing of the mating surface.

[0036] In this embodiment, the coating 5 is nickel-plated by chemical plating technology and is evenly plated on the surface of the connecting layer 3 and the reinforcing rib 4 .

[0037] It should be noted that chemical plating is a method of depositing a metal coating on the surface of a workpiece through a chemical reaction. Nickel plating forms a coating with good conductivity and wear resistance on the surface of the guide sleeve, thereby ensuring the durability and wear resistance of the guide sleeve.

[0038] Beneficial effects:

[0039] The high-precision guide sleeve of the hydraulic matching part is streamlined by setting the cylinder 1 and the connection layer 3 near both ends to present a shape that is more in line with fluid dynamics, so as to reduce the impact and vortex generation of the fluid when entering and exiting, thereby reducing the flow resistance of the fluid inside the guide sleeve, making the fluid smoother during the flow process, and improving the working efficiency of the hydraulic cylinder. At the same time, the cylinder 1 is fixed by connecting the clamping groove 2 and the fixing groove 6, and the external strength of the guide sleeve is strengthened by setting the reinforcing rib 4. At the same time, the heat assembly method is used to increase the plasticity of the reinforcing rib 4 or the guide sleeve by heating it so that it can be better assembled together, and at the same time, sealant is applied at the connection to improve the sealing of the matching surface.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
