[0046] The utility model proposes a tooling for integrating the oil seal structure in the bottom cylinder of a shock absorber with two steps, which is used in the processing technology of the shock absorber bottom cylinder. The utility model does not limit the type of shock absorber, but the structure of the tooling for integrating the oil seal structure in the bottom cylinder of a shock absorber with two steps is particularly suitable for improving manual operation requirements.

[0047] In general, the tooling of the integrated two-step pressing shock absorber bottom cylinder inner oil seal structure proposed in the utility model mainly includes a frame 1, an oil seal installation assembly, a composite installation assembly, and a pressing assembly. Figure 1 , which shows the arrangement relationship of the frame 1, the oil seal installation assembly, the composite component installation assembly, and the pressing assembly.

[0048] In order to achieve the purpose of installing the dust cover and the oil seal in sequence in the integrated bottom cylinder in the same tooling, and to solve the problem in the background technology that vehicles often need to face various complex road conditions and impacts, and the shock absorber needs to withstand greater pressure and vibration, a high-strength oil seal structure is usually installed in the end of the bottom cylinder, including a composite structure formed by the mutual sleeve of a flat retaining spring, a gasket and a composite part. Here, not only good material quality is required, but also the accuracy of the installation position and the relative strength between the components after installation are required, so as to prevent the leakage of internal oil and the entry of external impurities and moisture into the oil cylinder. For this reason, in the technical solution provided in this embodiment, respective positioning components, oil seal installation components and composite component installation components are provided for the oil seal and the composite parts near the oil seal. In addition, the fixed block in the component is used to effectively ensure that the component, the bottom cylinder and the top cylinder are on the same vertical center line, which can effectively ensure that the oil seal structure in the bottom cylinder is installed in place, save manpower and material resources, and effectively improve the installation efficiency, and obtain good quality assurance.

[0049] like Figure 1As shown, a frame 1 is placed on the ground, a workbench 2 close to the manual operation position is installed on the frame 1, an oil seal installation assembly corresponding to the pressing and installing of the oil seal and a composite component installation assembly corresponding to the pressing and installing of the composite component are placed on the workbench 2, and a pressing assembly is correspondingly arranged on the top of the oil seal installation assembly and the composite component installation assembly on the frame 1. When working, ensure that the pressing assembly is on the same vertical center line as the oil seal installation assembly, the composite component installation assembly and the bottom cylinder, so as to achieve the effect of fast and accurate installation.

[0050] It should be specifically explained that in this embodiment, the oil seal is first installed, and an oil seal installation assembly is configured for this purpose, wherein a pair of oil seal installation bearing seats 4 are provided and arranged on the left and right, and the two ends of the first rotating shaft 5 extend out of the rotating shaft and are installed in the oil seal installation bearing seats 4 on both sides through bearings, and an oil seal positioning column 3 is vertically installed on the first rotating shaft 5;

[0051] Since this structural part corresponds to the installation of the oil seal, the oil seal positioning column 3 includes an integrally arranged bottom column 31 and a guide column 32 from bottom to top, wherein the outer diameter of the bottom column 31 is the same as the outer diameter of the oil seal, that is, the oil seal is placed on the base 31 before installation; then, in order to ensure the coaxial arrangement of the oil seal, the bottom cylinder and the down-pressing assembly, a No. 1 fixing block 6 is installed on one end of the No. 1 rotating shaft 5 and on the outside of the oil seal mounting bearing seat 4. When the No. 1 fixing block 6 is away from the end of the No. 1 rotating shaft 5 and abuts against the workbench 2, the oil seal positioning column 3 is arranged vertically upward, so that when the down-pressing assembly is working, the oil seal positioning column 3, the bottom cylinder and the down-pressing assembly are on the same vertical center line.

[0052] As mentioned above, a multi-step operation tool is provided in this embodiment. Therefore, after the oil seal installation assembly is completed, the semi-finished bottom cylinder will be manually transferred to the composite component installation assembly for the next pressing process. Here, the gasket and the composite component are pressed into the bottom cylinder. Since the size structure of the gasket and the composite component is different from that of the bottom cylinder, and the installation height in the bottom cylinder is also different, the composite component installation assembly will be configured to include a composite component bearing seat 7, a composite component positioning column 8, and a second rotating shaft 9. Figure 3 As shown, a pair of composite bearing seats 7 are provided and arranged on the left and right. The two ends of the second rotating shaft 9 extend out of the rotating shaft and are installed in the composite bearing seats 7 on both sides through bearings. The composite positioning column 8 is vertically arranged, and the bottom sleeve is installed on the second rotating shaft 9. In order to match the installation and positioning of the composite part, the composite positioning column 8 includes, from bottom to top, a limit column 81, a support column 82 and a guide column 83 which are integrally arranged and have gradually decreasing outer diameters, wherein a composite part is placed on the support column 82, and the outer diameter of the limit column 81 is the same as the outer diameter of the bottom cylinder, which is used to prevent the bottom cylinder from being further pressed down under the pressure of the pressing component, resulting in interference installation.

[0053] On this basis, it is also necessary to realize that when the pressing assembly is working, the composite part positioning column 8, the bottom cylinder and the pressing assembly are on the same vertical center line. Therefore, a No. 2 fixing block 10 is installed on one end of the No. 2 rotating shaft 9 and located on the outside of the composite part bearing seat 7. When the No. 2 fixing block 10 is away from the end of the No. 2 rotating shaft 9 and is against the workbench 2, the composite part positioning column 8 is set vertically upward.

[0054] like Figure 4 As shown in the figure, the structure of the pressing assembly is shown. The bottom cylinder processed in this embodiment is very long relative to the height of the oil seal and the composite part. The oil seal and the composite part are located at the bottom of the bottom cylinder when installed, and the part where the pressing force of the pressing assembly is located at the top of the bottom cylinder. Considering the quality of installation, the structure in the pressing assembly includes a cylinder mounting seat 11, a cylinder 13, an adjusting screw 14 and a pressing block 15. The cylinder mounting seat 11 is arranged above the workbench 2 in parallel, and both ends are supported on the workbench 2 by columns 12, which can provide stable support for the installation of the cylinder 13, so the cylinder 13 is The cylinder seat is installed on the upper surface of the cylinder mounting seat 11. When in use, the cylinder shaft vertically passes through the cylinder mounting seat 11, one end of the adjusting screw 14 is connected to the cylinder shaft through the cylinder joint, and the lower pressure block 15 is threadedly connected to the other end of the adjusting screw 14 and moves up and down with the drive of the cylinder 13. According to the installation height required by different products, the height between the lower pressure block 15 and the adjusting screw 14 is locked by a locking nut 16; further, each cylinder 13 at the top corresponding to the bottom of the frame 1 is provided with its own foot control switch 17, which is convenient for the operator to control the cylinder.

[0055] Preferably, in order to ensure that the force applied to the bottom tube is dispersed and uniform during the process of applying pressure to the bottom tube, the lower pressure block 15 is arranged in an inverted T-shaped structure, including a horizontal end and a vertical end, and the horizontal end is arranged at the bottom, but the outer diameter of the horizontal end is larger than the outer diameter of the bottom tube.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
