[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To effectively illustrate the embodiments of this utility model, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] This application discloses a riveting and positioning device for a compression valve rod, including a riveting machine 1, a guide and clamping mechanism, a base plate 9, and a positioning base 7 disposed on the base plate 9. The guide and clamping mechanism includes a guide plate 5, a guide rod 6, and a clamping cylinder 2. The driving end of the clamping cylinder 2 is fixedly connected to the guide plate 5. The bottom of the riveting machine 1 passes through the guide plate 5. The guide plate 5 is slidably connected to the guide rod 6. The bottom of the riveting machine 1 is correspondingly disposed with the positioning base 7.

[0022] In practice, the clamping cylinder 2 can be supported and fixed by a support device, and the guide rod 6 can be directly fixed to the base plate 9, allowing the guide plate 5 to slide along the guide rod 6. This enables the clamping cylinder 2 to move up and down, thereby driving the guide plate 5 to clamp the workpiece. Then, the riveting machine 1, which is aligned with the workpiece, presses down to rivet it, thus achieving the riveting of the workpiece. Not only can the positioning base 7 achieve the positioning of the workpiece, but the clamping cylinder 2 can also further clamp and position the workpiece, allowing the riveting machine 1 to achieve riveting under the guidance of the guide plate 5. This not only effectively ensures the versatility of different workpieces by adjusting the length of the cylinder, but also guarantees the riveting effect of the product.

[0023] The above is merely one illustrative feasible implementation scheme; the specific structural details are not shown in the accompanying drawings. This automatic cylinder-guided pressing mechanism consists of two guide cylinders, a guide plate 5, and a guide rod 6. The pressing position can be adjusted by changing the length of the pull rod cylinder, ensuring versatility. Further details are not elaborated here.

[0024] In the specific implementation process, please refer to the appendix. Figure 1 As shown, this application discloses a compression valve rod riveting and positioning device. Figure 1As shown, the compression valve rod riveting positioning device includes a base plate 9 and a positioning base 7 set on the base plate 9. A support column 8 is set at each end of the base plate 9 (which can be symmetrical with respect to the positioning base). One end of the support column 8 is fixedly connected to the base plate 9, and the other end is fixedly set with a mounting plate 4. The two support columns 8 are at the same height, thus ensuring that the mounting plate 4 is set parallel to the base plate 9. A clamping cylinder 2 is installed on the mounting plate 4 through a support rod 3. A guide rod 6 is installed at the bottom of the mounting plate 4. The two guide rods 6 are set parallel to each other and are respectively close to the corresponding support column 8. A guide plate 5 is slidably sleeved on the guide rod 6. The guide plate 5 is set parallel to the mounting plate 4 and the base plate 9, and the guide plate 5 and the mounting plate 4 are both provided with corresponding openings in the middle position. The openings allow the riveting end of the riveting machine 1 to pass through, so that the riveting end of the riveting machine 1 is directly facing the positioning base 7, thereby realizing the riveting of the workpiece by the riveting machine 1.

[0025] In the specific implementation process, the positioning base 7 includes a base and a positioning seat. The base and the base plate 9 are centered and connected. The positioning seat is set on the base. Specifically, the bottom of the positioning seat is embedded with a magnet, and the outside of the positioning seat is provided with a truncated pyramid, which automatically positions the outer surface of the compression valve and the bottom surface of the light rod, ensuring the accuracy of workpiece positioning.

[0026] In the specific implementation process, the mounting plate 4 is fixed parallel to the base plate 9 by the support column 8, the guide rod 6 is fixed to the lower part of the mounting plate 4, the guide plate 5 is set below the mounting plate 4, and the clamping cylinder 2 is installed on the upper part of the mounting plate 4 through the support rod 3, and the telescopic end of the clamping cylinder 2 passes through the mounting plate 4 and is fixedly connected to the guide plate 5. Of course, in the specific implementation process, there are two clamping cylinders 2, and the two clamping cylinders 2 are symmetrically arranged on the mounting plate 4, with the riveting machine 1 as the symmetrical point.

[0027] The compression valve smooth rod riveting positioning device disclosed in this utility model increases guiding stability through the automatic forward and backward function of the clamping cylinder 2. After the workpiece is pressed by the clamping 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 guaranteed. At the same time, the riveting displacement can be adjusted according to the length of the workpiece, thereby realizing automatic switching between different products, which effectively improves the riveting efficiency and riveting effect, and thus enhances the performance and reliability of the vibration damper.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
