[0017] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will further describe the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0018] For an effective description of the embodiments of the present invention, the embodiments of the present application will be elaborated in detail with reference to the accompanying drawings below.

[0019] The present application discloses a compression valve polished rod riveting positioning device, which includes a riveting machine 1, a guiding and pressing mechanism, a bottom plate 9, and a positioning base 7 arranged on the bottom plate 9. Among them, the guiding and pressing mechanism includes a guiding plate 5, a guiding rod 6, and a pressing cylinder 2. The driving end of the pressing cylinder 2 is fixedly connected to the guiding plate 5. The bottom of the riveting machine 1 penetrates through the guiding plate 5. The guiding plate 5 is slidably connected to the guiding rod 6. The bottom of the riveting machine 1 is correspondingly arranged with the positioning base 7.

[0020] In the specific implementation process, the pressing cylinder 2 can be supported and fixed by a supporting device. The guiding rod 6 can be directly fixed to the bottom plate 9, enabling the guiding plate 5 to slide along the guiding rod 6. Thus, the up-and-down movement of the telescopic end of the pressing cylinder 2 drives the guiding plate 5 to press the workpiece. Then, the riveting machine 1 that is aligned with each other presses down for riveting, thereby realizing the riveting of the workpiece. It can not only position the workpiece through the positioning base 7, but also further press and position the workpiece through the pressing cylinder 2. As a result, the riveting machine 1 realizes riveting under the guiding action of the guiding plate 5. It can not only effectively ensure the versatility of different workpieces by adjusting the length of the cylinder, but also ensure the riveting effect of the product.

[0021] The above is only a feasible implementation scheme shown. The specific structure drawings are not shown in the specification drawings. The automatic guiding and pressing mechanism of the cylinder is composed of two cylinders with guiding, the guiding plate 5, and the guiding rod 6. The position of the press-fitting can be adjusted by adjusting the length of the pull rod cylinder to ensure versatility. Details are not elaborated here.

[0022] In the specific implementation process, reference can be made to the attached Figure 1 As shown, a compression valve polished rod riveting positioning device disclosed in the present application is shown. As Figure 1 shown, the compression valve polished rod riveting positioning device includes a bottom plate 9 and a positioning base 7 arranged on the bottom plate 9. At both ends of the bottom plate 9 (which can be symmetric with the positioning base), a support column 8 is respectively arranged. One end of the support column 8 is fixedly connected to the bottom plate 9, and the other end is fixedly provided with a mounting plate 4. The heights of the two support columns 8 are the same, thereby ensuring that the mounting plate 4 is parallel to the bottom plate 9. The pressing cylinder 2 is installed on the mounting plate 4 through a support rod 3. The bottom of the mounting plate 4 is provided with a guiding rod 6. The two guiding rods 6 are arranged in parallel and are respectively close to the corresponding support columns 8. A guiding plate 5 is slidably sleeved on the guiding rod 6. The guiding plate 5 is parallel to the mounting plate 4 and the bottom plate 9. Corresponding openings are arranged in the middle positions of the guiding plate 5 and the mounting plate 4. The openings can enable the riveting end of the riveting machine 1 to penetrate, so that the riveting end of the riveting machine 1 is directly opposite to the positioning base 7, realizing the riveting of the workpiece by the riveting machine 1.

[0023] In the specific implementation process, the positioning base 7 includes a base and a positioning seat. The base is centeringly connected to the bottom plate 9, and the positioning seat is arranged on the base. Specifically, a magnet is embedded at the bottom of the positioning seat, and a frustum is arranged outside the positioning seat to automatically position the outer surface of the compression valve and the bottom surface of the optical rod, ensuring the accuracy of workpiece positioning.

[0024] In the specific implementation process, the mounting plate 4 is fixedly parallel to the upper part of the bottom plate 9 by the support columns 8. The guide rod 6 is fixed to the lower part of the mounting plate 4. The guide plate 5 is arranged below the mounting plate 4. The pressing cylinder 2 is installed on the upper part of the mounting plate 4 through the support rod 3, and the telescopic end of the pressing cylinder 2 penetrates through the mounting plate 4 and is fixedly connected to the guide plate 5. Of course, in the specific implementation process, there are two pressing cylinders 2, and the two pressing cylinders 2 are symmetrically arranged on the mounting plate 4 with the riveting machine 1 as the symmetry point.

[0025] The compression valve optical rod riveting positioning device disclosed by the present invention increases the guiding stability through the automatic forward and backward functions of the pressing cylinder 2. After the workpiece is pressed by the pressing cylinder 2 before the compression valve is riveted, the riveting machine 1 starts to work. According to the force-displacement control of the riveting machine 1, the riveting effect of the product is ensured. At the same time, the riveting displacement can be adjusted according to the length of the workpiece, so as to realize automatic switching between different products, effectively improving the riveting efficiency and the riveting effect, and further enhancing the performance and reliability of the shock absorber.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
