Description

Technical Field

[0001] The utility model relates to a bushing riveting and pressing device, belonging to the technical field of mechanical automation. Background Art

[0002] Bushings are often attached to mechanical components. Their use can reduce wear, vibration, and noise between equipment, and also provide corrosion protection. Bushings also facilitate maintenance of mechanical equipment and simplify its structure and manufacturing process. In valve applications, bushings are installed inside the valve cover to enclose the valve stem, reducing leakage and achieving a sealing effect. In bearing applications, bushings can reduce wear between the bearing and the shaft seat and prevent increased clearance between the shaft and the bore. Due to their wide range of applications, bushings come in a wide variety of types. Choosing the appropriate bushing requires considering its intended use.

[0003] Among them, copper bushings have excellent performance in various industrial applications due to their excellent wear resistance, good corrosion resistance, and strong compressive resistance. In particular, copper bushings can provide reliable support and protection in working environments that require high loads and high sliding speeds. At present, copper bushings and products can only be pressed together by hydraulic presses. However, with the development of technology, higher requirements have been placed on the precision of the press-fitting of copper bushings and products. However, at this stage, there is no suitable jig for the riveting and pressing of copper bushings, and it is impossible to well control the runout of the copper bushings when they are pressed in, resulting in a lack of riveting and pressing accuracy. Therefore, there is an urgent need for a bushing riveting and pressing device with higher precision. Utility Model Content

[0022] This embodiment provides a bushing riveting press-in device, such as Figures 1 to 3 As shown: It includes an upper positioning plate 1 and a lower positioning plate 2. The positioning column 3 is supported on the upper part of the lower positioning plate 2. The positioning column 3 is connected through the guide hole opened at the corresponding position on the upper positioning plate 1. The upper positioning plate 1 has a mounting hole embedded in the embossed guide block 4. The lower positioning plate 2 also has a mounting hole embedded in the product guide block 7. The upper end of the product guide block 7 is connected to the product positioning block 8. The press-fitted product is placed in the product positioning block 8. The lower end of the embossed guide block 4 is connected to the lower pressure head 5, and the position of the lower pressure head 5 corresponds to the product positioning block 8. Embedding the product guide block 7 in the lower positioning plate 2 and the embossed guide block 5 in the upper positioning plate 1 can complete the stable connection between the product guide block 7 and the embossed guide block 5, ensuring that the position of the press-fitted product is fixed during the press-fitting operation, and the press-fitted product is not easily displaced. It can effectively control the bounce of the press-fitted product and improve its stability and safety.

[0023] This embodiment also includes an inwardly defined notch on one end of the product positioning block 8, which is configured as a contoured structure that aligns with the press-fit product. This notch on the product positioning block 8, configured as a contoured structure that aligns with the size and shape of the copper bushing in the press-fit product, securely secures the copper bushing within the product positioning block 8, and further ensures that product runout during press-fitting is controlled within a specified range.

[0024] This embodiment also includes adding an elastic guide sleeve 6 at the connection between the positioning column 3 and the upper positioning plate 1. The lower end surface of the lower pressure head 5 is provided with an embossing structure. The use of the elastic guide sleeve 6 can enable the upper positioning plate 1 to quickly return to its initial position before press-fitting along the positioning column 3 after being pressed down, and protect the connection between them, thereby effectively extending its service life. When in use, the embossing guide block 4 first drives the lower pressure head 5 to contact the press-fitted product, and then the embossing operation of the press-fitted product is completed by the embossing structure on the lower pressure head 5. The embossing operation is completed directly during the press-fitting process, saving the production cost of the press-fitted product and also improving its production efficiency.

[0025] Method of using the utility model

[0026] Before use, first place the copper bushing to be press-fitted within the product positioning block 8. By securing the copper bushing within the product positioning block 8, the product runout during press-fitting can be controlled to within 0.15mm. Next, place the product to be press-fitted above the copper bushing, ensuring that it remains level. This utility model uses a hydraulic press to perform the downward pressure, and the pressure value of the hydraulic press needs to be adjusted to 45N.

[0027] When in use, you need to first make sure that the product is placed horizontally, and then press the start switch of the hydraulic press. The hydraulic press outputs pressure to the embossing guide block 5, and the embossing guide block 5 moves downward along the positioning column 3 together with the upper positioning plate 1. When the embossing guide block 5 descends, it drives the lower pressure head 6 to first contact the horizontally placed product, and then presses the product and the copper bushing together. Then continue to press down, and the embossing operation of the product is completed through the embossing pattern on the lower end face of the lower pressure head 6. During the embossing process, it is necessary to ensure that the flatness of the product after pressing is 0.1mm. Then turn off the hydraulic press, and the upper positioning plate 1 rises and returns to the position before pressing down with the help of the elastic guide sleeve 6. At this time, the operator can take out the product that has been riveted and pressed from the product positioning block 8, place it in the designated area, and complete the press-fitting embossing operation of the product and the copper bushing. The operator will then continue to perform the riveting and pressing operation of the next product.
