Description

Technical Field

[0001] This invention relates to the field of aluminum automotive parts manufacturing, and in particular to a riveting fixture for a door sill beam assembly. Background Technology

[0002] With the increasing proportion of new energy vehicles, major domestic automakers have begun to adopt lightweight aluminum components to reduce vehicle weight and increase mileage. However, some key load-bearing components require reinforcements inside the aluminum profiles. Traditionally, door sill beams add mounting points using rivets and nuts, but this method lacks sufficient local rigidity at the mounting points, failing to meet the requirements of areas with high loads, such as battery packs. Therefore, it is necessary to add nut reinforcement plates. Because the profile beam is closed from top to bottom, the reinforcement plates can only be inserted through a cavity. The cavity space is narrow and long, and traditional methods generally involve manual operation, which is inefficient, difficult, and prone to misplacement or omission of components. Summary of the Invention

Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0017] like Figures 1-6 As shown, a door sill beam assembly riveting fixture includes a frame 100. The frame has a material support beam placement area 110 on the left and a riveting area 120 on the right. The riveting area has clamping devices 200 at both ends for fixing the door sill beam. The material support beam placement area has a material support beam 300 and a driving device for driving the material support beam to move to the right and extend into the door sill beam cavity. The material support beam 300 has several grooves 310 on its upper side for placing reinforcing plates. The number of support beams matches the number of cavities in the sill beam, and their positions correspond one-to-one. The grooves on the support beams correspond to the positions on the sill beams where reinforcing plates need to be installed. The reinforcing plates are placed in the grooves on the support beams, and then the support beams move backward and extend into the cavities of the sill beams, delivering the reinforcing plates to the designated positions. The rivet holes on the reinforcing plates correspond one-to-one with the rivet holes on the sill beams, and then the rivets are manually installed. This sill beam assembly rivet fixture solves the problem of reinforcing plate feeding, improves the efficiency of sill beam reinforcing plate rivetting, reduces operational difficulty, and solves the problems of misplaced or missing parts.

[0018] In this embodiment, the driving device includes a linear slide 400, which is an electric linear slide. The slide of the linear slide 400 is provided with a fastening mechanism for fixing the material support beam, and a first support wheel 130 for supporting the material support beam is provided at the right end of the linear slide.

[0019] In this embodiment, the fastening mechanism includes a pressure plate 410 located on the upper side of the material support beam. The pressure plate presses the material support beam with fastening bolts 420. After passing through the pressure plate and the material support beam, the fastening bolts are locked onto the slide of the linear slide table. The material support beam is designed as a detachable structure, which can realize the quick replacement of the material support beam.

[0020] In this embodiment, the clamping device 200 includes a support mechanism 210, a clamping mechanism 220, and a positioning mechanism 230. The support mechanism 210 includes a base plate 211 and a liftable support plate 212 located above the base plate. The support plate is provided with a limiting plate 213 for abutting against the side of the sill beam and a support column 214 for supporting the sill beam. A pair of support columns are provided. A lifting cylinder 215 for driving the support plate to rise and fall is installed on the base plate. Several guide columns are connected to the bottom of the support plate. The base plate is provided with a guide sleeve that slides with the guide columns. The lifting cylinder 215 is installed on the lower side of the base plate. The telescopic rod of the lifting cylinder 215 passes through the base plate and connects to the support plate. The lifting function of the support plate is set to avoid the material support beam scraping against the upper side wall of the sill beam cavity when it extends into the cavity. Before the material support beam extends in, the support plate is raised to a certain height. After the material support beam extends into place, the sill beam descends, so that the upper side wall of the sill beam cavity is pressed tightly against the reinforcing plate on the material support beam.

[0021] In this embodiment, the clamping mechanism 220 includes a first fixed bracket 221 whose lower end is connected to the support plate 212. The upper end of the first fixed bracket is hinged to the middle of a clamping bracket 222. A pressure block 223 is connected to the front end of the clamping bracket. The rear end of the clamping bracket is hinged to the telescopic rod of a clamping cylinder 224. The clamping cylinder is hinged to the first fixed bracket. When the clamping cylinder extends, the front end of the clamping bracket swings down, and the pressure block 223 presses against the upper side of the end of the sill beam.

[0022] In this embodiment, the positioning mechanism 230 includes a second fixed bracket 231 with its lower end connected to the base plate. The upper part of the second fixed bracket is provided with a positioning rod 233 that is driven to move up and down by a telescopic cylinder 232. The lower end of the positioning rod 233 is tapered. A guide seat 234 is connected to the front side of the upper part of the second fixed bracket. The guide seat has a sliding guide hole for the positioning rod. The sill beam 500 has a positioning hole 510 that matches the positioning rod. The positioning rod is used to position the sill beam. Before the sill beam is clamped, the positioning rod moves downward to insert into the positioning hole of the sill beam. If the positioning hole and the positioning rod are misaligned, the position of the sill beam is adjusted. After the positioning rod is inserted into the positioning hole, the clamping mechanism 220 clamps the sill beam, and then the positioning rod is lifted and withdrawn from the positioning hole.

[0023] In this embodiment, a swing frame 235 is provided above the positioning rod and is hinged to the upper part of the second fixed bracket and can swing up and down. The swing frame has a clearance slot 236 for the telescopic rod of the telescopic cylinder to pass through. A connector 237 is connected to the upper end of the positioning rod. A connecting rod 238 is connected between the connector and the swing rod so that the positioning rod moves up and down when the swing frame swings up and down. One end of the swing frame is hinged to the second fixed bracket, and the other end is connected to a handle. The swing frame is controlled to swing up and down by the handle. The upper end of the positioning rod is connected to the telescopic rod of the telescopic cylinder. The positioning rod can be driven to move up and down by the telescopic cylinder, or it can be manually controlled to move up and down by the handle.

[0024] In this embodiment, a second support wheel 140 for supporting the material support beam is provided on the right side of the clamping device at the right end of the riveting area; both the first and second support wheels are provided with annular limiting grooves adapted to the material support beam, and the annular limiting grooves can prevent the material support beam from swaying during movement; when the material support beam is in the material support beam placement area, the slide of the linear slide table is at the left end, the left end of the material support beam is fixed on the slide, and the right end rests on the first support wheel; when the slide table pushes to the right, it pushes the material support beam into the cavity of the sill beam, the material support beam passes through the sill beam, and the right end of the material support beam rests on the second support wheel, preventing the right end of the material support beam from being suspended in the air.

[0025] In this embodiment, a sensor for sensing the reinforcing plate is provided below each groove of the material support beam. The material support beam is a hollow structure with a rectangular cross-section, and the groove positions communicate with the inner cavity of the material support beam. The sensor located below the groove is installed in the inner cavity of the material support beam. The working process of the riveting fixture for the door sill beam assembly: Sensors are installed inside each groove to detect whether the reinforcing plate is placed correctly, ensuring accurate placement without any omissions. The alignment of the reinforcing plate riveting holes with the sill beam riveting holes is pre-set. The sill beam is placed on the support plates at both ends, and its position is confirmed by the positioning holes. Then, the clamping mechanism clamps the sill beam. A lifting cylinder drives the support plate to rise a certain height to avoid interference or scraping when the support beam moves to the right. A linear slide controls the support beam to move to the right, sending the reinforcing plate into the sill beam cavity. When the support beam is fully inserted, the linear slide stops working, and the lifting cylinder drives the support plate to descend, pressing the upper side wall of the sill beam cavity tightly against the reinforcing plate on the support beam, aligning the riveting holes one by one. Then, manual riveting is performed.
