[0002] Currently, riveting is widely used in the assembly process of automotive parts. The existing riveting process generally fixes the parts on the positioning fixture, and then the riveting device moves to the position of the parts to rivet them. The existing positioning fixture can only position one set of parts at a time, and the positioning is unstable, which causes the parts to loosen during the riveting process and thus damage the parts. Utility Model Content

Both sides of the mounting plate are mounting end faces to simultaneously position two sets of parts. Each mounting end face is provided with a first positioning post, and the base plate is provided with a second positioning post. A clamping cylinder is provided on the base plate, and a pressure rod is provided at the output end of the clamping cylinder. A support post is provided on the mounting end face corresponding to the position of the pressure rod.

[0004] Furthermore, the part positioning and clamping fixture also includes a servo motor, the output end of which is connected to the base plate via a lead screw, and guide rails are respectively provided on both sides of the lead screw, with the base plate mounted on the guide rails.

[0005] Furthermore, the pressure bar is a rubber pressure bar, which can prevent damage to the parts.

[0006] Furthermore, two sets of clamping cylinders are set on one side of each of the mounting end faces at a preset interval.

[0007] Furthermore, a support block is provided on the mounting end face near the support column.

[0008] Furthermore, an adjustment plate is provided on the base plate, and the second positioning post is provided on the adjustment plate, forming a detachable connection between the adjustment plate and the base plate.

[0009] The advantages of this application are: the provided part positioning and clamping fixture can position two parts at once, and the clamping is stable, and can accurately move the parts to the riveting position, thereby improving the riveting efficiency. Attached Figure Description

[0013] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0014] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. 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.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] See Figures 1-2 This embodiment provides a part positioning and clamping fixture, including a base plate 10, which is rectangular in shape. A mounting plate 11 is vertically arranged in the middle of the base plate 10. Both sides of the mounting plate 11 are mounting end faces to simultaneously position two sets of parts. A first positioning post 12 is provided on each mounting end face. Since the part in this embodiment is relatively long and the riveting position is on the side wall near one end of the part, the first positioning post 12 is used to support one end of the part. An adjusting plate 13 is provided at the edge of the base plate, and a second positioning post 14 is provided on the adjusting plate 13. The second positioning post 14 is used to support the other end of the part.

[0020] Preferably, the adjusting plate 13 is detachably connected to the base plate, such as by bolts, which facilitates the replacement of adjusting plates of different sizes, thereby adapting to parts of different specifications and improving the compatibility of the tooling.

[0021] The size and shape of the first positioning post 12 and the second positioning post 14 are determined according to the size and shape of the inner hole of the part. Generally speaking, the basic positioning needs can be met by supporting and positioning the two ends of the part. If necessary, positioning posts can be set at the corresponding positions on the mounting plate 11 for support according to the shape characteristics of the part itself.

[0022] To prevent parts from falling off, clamping cylinders 15 are respectively installed on the bottom plates on both sides of the mounting plate 11. In this embodiment, two sets of clamping cylinders are provided on each side. The position of the cylinders is determined according to the riveting position of the parts. A pressure rod 16 is provided at the output end of the clamping cylinder 15. To prevent the parts from being deformed by pressure, a support column 17 is provided on the mounting end face corresponding to the position of the pressure rod 16. A support block 18 is also provided near the support column 17 to form support while the pressure rod presses against the parts. At the same time, the pressure rod 16 is made of rubber to prevent damage to the parts.

[0023] In the actual riveting process, due to the influence of the equipment's own structure, the riveting device cannot be moved precisely to the part position. Therefore, a servo motor 19 is also set below the base plate 10. The output end of the servo motor 19 is connected to the base plate 10 through a lead screw 20. Guide rails 21 are set on both sides of the lead screw 20, and the base plate 10 is set on the guide rails.

[0024] Working principle: The part 22 is placed on the mounting plate by the first positioning post 12 and the second positioning post 14. Then the clamping cylinder is started, which drives the pressure rod 16 to clamp the part. Then the servo motor 19 drives the base plate through the lead screw to move the part to the designated riveting position.

[0025] 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.
