Abstract
Description
Technical Field

[0002] In the assembly line of automotive parts, bushings need to be pressed onto the parts. Since the parts to be pressed are in an automated production line, they are generally fixed by positioning fixtures. After being transported to the pressing position, the pressing equipment presses them. Existing pressing equipment generally presses them directly from above, relying solely on the fixing structure of the positioning fixture itself. This can cause the parts to shake during the pressing process, which can lead to damage to the parts. Utility Model Content

It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0017] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.
[0018] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0019] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] See Figures 1-3 This embodiment provides a bushing pressing device, including a column 10, which is generally U-shaped and side-mounted. A gas-liquid booster cylinder 11 and a pressing cylinder 12 are provided at the top of the column 10. A pressing head 13 is provided at the output end of the gas-liquid booster cylinder 11, and a pressure plate 14 is provided at the output end of the pressing cylinder 12. A support assembly 15 is provided at the bottom of the column 10.
[0022] Specifically, the support assembly 15 includes a lifting cylinder 151, a support rod 152 is provided at the output end of the lifting cylinder 151, a positioning post 153 is provided at the free end of the support rod 152, a support end face 154 is provided on the support rod outside the positioning post 153, the support end face 154 is used to support the bottom of the bushing, and the positioning post 153 is used to insert into the inner hole of the part.
[0023] To further support the parts from below, a guide plate 155 is connected to the bottom of the column 10. A transverse cylinder 156 is installed on the guide plate 155. A support block 157 is installed at the output end of the transverse cylinder 156. The support block 157 and the guide plate 155 are slidably connected. A lifting plate 158 is installed at the output end of the lifting cylinder 151. A support rod 152 is installed on the lifting plate 158. The support block 157 can be moved to below the lifting plate 158.
[0024] To adjust the height of the support block, a thickening block 159 is provided on the support block 157. The thickening block 159 and the support block are detachably connected, such as by screws, so as to facilitate the replacement of thickening blocks of different thicknesses. In addition, since the support block needs to be moved to the bottom of the lifting plate, an avoidance groove 150 is opened inward along the side of the support block near the lifting plate to avoid the push rod at the output end of the lifting cylinder.
[0025] In addition, a connecting bracket 16 is provided at the output end of the gas-liquid booster cylinder 11, and a vertical guide rail 101 is provided on the column 10. The connecting bracket 16 is movably connected to the vertical guide rail 101. A mounting plate 17 is provided on the connecting bracket 16, and the pressing head 13 is movably mounted on the mounting plate 17. A guide rod 18 is provided between the pressing head and the connecting bracket, and a spring 19 is sleeved on the guide rod to achieve buffering during the pressing of the bushing.
[0026] The bushing pressing equipment of this application is used to be installed on the assembly line. When the part moves to the pressing position, the pressing cylinder 12 drives the pressing plate 14 to press the part from above. The lifting cylinder 151 drives the support rod 152 to rise until the support end face 154 abuts against the bottom of the bushing. Then the lateral cylinder 156 drives the support block to move forward to support the lifting plate. Subsequently, the pneumatic-hydraulic booster cylinder 11 starts to drive the pressing head to press the bushing. Since it may be necessary to press two sets of parts at the same time, two pressing stations are set in this embodiment.
[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
