[0023] See also Figures 1-4The utility model provides a technical solution: a hydraulic component with high assembly precision, including a processing table 1, two conveying tables 2 are installed on the top of the processing table 1, and the interiors of the two conveying tables 2 are provided with conveyor belts 3 for conveying processing accessories. The two conveyor belts 3 for conveying different components are used to assemble different components subsequently. A fixed table 4 is installed on the top of the processing table 1, and a lifting platform 5 is installed on the top of the fixed table 4. A lifting mechanism is provided inside the lifting platform 5, and an electric slide rail 8 is provided on the front side of the lifting platform 5. An electric slider 10 is installed for sliding inside the electric slide rail 8. A two-way cylinder 11 is installed on one side of the electric slider 10 and the fixed table 4, one of which is used to fix the position of the component being conveyed, and the other is used to fix the position of the component being conveyed. 11 is used to transfer the assembly parts being transported.

Multiple adjusting rods 14 are threadedly installed inside the multiple adjusting seats 13. Buffer grooves 15 are provided inside the multiple adjusting rods 14. Buffer components for fixing the processing position of accessories are provided inside the multiple buffer grooves 15. An automated assembly method is adopted. The buffer components for fixing the transferred assembly parts are driven by the lifting mechanism to fix the parts transported on the corresponding conveyor belt 3. The assembly parts clamped and fixed by the extrusion head 18 are moved to the corresponding conveyor belt 3 for assembly in conjunction with the electric slide rail, thereby replacing traditional manual assembly and greatly improving the assembly accuracy of the parts.

[0024] like Figure 2 As shown, the lifting mechanism includes a screw rod 6, which is rotatably installed inside the lifting platform 5, and a lifting block 7 is threadedly installed on the rod wall of the screw rod 6. The lifting block 7 is slidably installed inside the lifting platform 5. One side of the lifting block 7 is installed on the electric slide rail 8, and a drive motor 9 is installed on the upper end of the screw rod 6. The drive motor 9 is installed on the lifting platform 5. The screw rod 6 in the lifting mechanism is driven to rotate by the drive motor 9. The lifting block 7 threadedly installed on the rod wall of the screw rod 6 slides along the inside of the lifting platform 5 when the screw rod 6 rotates, driving the electric slide rail 8 and the components thereon to move up and down, thereby driving one group of buffer components to move up and down together, thereby realizing the transfer and processing of the components being transported.

[0025] like Figure 3 and 4As shown, the buffer assembly includes a buffer spring 16, which is installed inside the buffer groove 15, and a slider 17 is installed at one end of the buffer spring 16, and an extrusion head 18 is threadedly installed at the other end of the slider 17.

When the component needs to be fixed, the two-way cylinder 11 pushes the adjustment seat 13 to move, so that the extrusion head 18 is close to the component. Through the buffering action of the buffer spring 16, the extrusion head 18 can stably clamp the fixed component. An adjustment groove 20 is opened on one side of the multiple adjustment rods 14, and the adjustment groove 2 is provided to facilitate the rotation of the adjustment rod 14 inside the adjustment seat 13.

[0026] The working principle is as follows: in the actual high-precision hydraulic component assembly and processing of the utility model, the processing accessories of the hydraulic components are transported through the conveyor belt 3 inside the two conveyor platforms 2. When the components stop at the specified position, the lifting mechanism starts to work, and the screw rod 6 in the lifting mechanism is driven to rotate by the drive motor 9. The lifting block 7 threadedly installed on the wall of the screw rod 6 slides along the inside of the lifting platform 5 when the screw rod 6 rotates, driving the electric slide rail 8 and the components on it to move up and down. The electric slider 10 inside the electric slide rail 8 and the two-way cylinder 11 on one side of the fixed platform 4 work together. The connecting plates 12 at both ends of the two-way cylinder 11 are connected to the adjustment seat 13. The internal thread of the adjustment seat 13 is installed with an adjusting rod 14. The adjusting rod The buffer assembly inside 14 is used to fix the processing position of the accessories. The buffer spring 16 in the buffer assembly is in the buffer groove 15, and one end is connected to the slider 17. The other end of the slider 17 is threadedly installed with an extrusion head 18, and the outer wall of the extrusion head 18 is provided with a buffer sleeve 19. When the component needs to be fixed, the two-way cylinder 11 pushes the adjustment seat 13 to move, so that the extrusion head 18 is close to the component. Through the buffering effect of the buffer spring 16, the extrusion head 18 can stably clamp the fixed component. After the component is fixed, the electric slide rail 8 drives the electric slider 10 to move, thereby moving the clamped and fixed assembly component to the corresponding conveyor belt 3 for assembly, realizing the automatic movement and positioning of the component and improving the assembly accuracy.

[0027] Principle of assembly process: Through the above-mentioned component conveying, positioning, fixing and moving processes, different hydraulic components are accurately moved to the corresponding positions for assembly. This automated assembly method avoids the problems of dimensional deviation and form and position tolerance that may occur in manual assembly, ensures the precise fit between various components, improves the assembly accuracy of hydraulic components, and meets the demand of modern hydraulic systems for high-precision hydraulic components.

The one-way cylinder 22 controls the position of the baffle 25 according to the feedback signal, so that the conveyed component just stays at the specified position for subsequent assembly operations.
