Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and in particular to a connecting rod filling device used in the side flange of a roof. Background Technology

[0002] Among automotive exterior body panels, the roof is a key component, and its shape is a relatively complex part. This type of part occupies a very important position in the car's appearance, requiring extremely high surface quality and dimensional accuracy. Its matching relationships are very complex, with strict compatibility with major components such as the tailgate and side panels. In particular, the negative angle flange forming on the two long sides overlapping with the side panels further increases the difficulty of the mold structure. Furthermore, the development cost of automotive component molds accounts for approximately one-fifth of the overall vehicle development investment.

[0003] To achieve the negative angle forming of the long side of the top cover, a structure with a side-flipping and filling punch is required. In the existing symmetrical oblique flipping process of the top cover, the commonly used filling method for the movable punch is the "wedge-push-wedge" form. The specific working process is as follows: a cylinder or forced drive oblique wedge guide plate pushes the transverse slider to move laterally. After the slider moves laterally, it pushes the filling punch upward through the wedge guide plate to fill, thereby completing the filling action of the filling punch in the oblique flipping process.

[0004] In the existing technical solution, in order to ensure high-precision fit between the components, a large number of guide plates, guide covers and other guiding elements are required for the transverse slider and filling punch, which greatly increases the debugging time and difficulty; at the same time, several polyurethane limit blocks for positioning and return are also required, which increases the procurement and processing costs; the weight of the casting is also too large, and the overall casting, processing, assembly and debugging costs are extremely high, which is not suitable for molds for small batch production.

Detailed Implementation

[0038] This invention addresses the technical problems of complex and costly side-flanging filling structures for automobile roofs in the prior art by providing a connecting rod filling device for use in side-flanging of roofs.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] This invention discloses a connecting rod filling device used in the side flange of a top cover, such as... Figure 1 As shown, it mainly includes: a driving part 2, a flanging filling part 3, and a limiting guide part 4. The driving part 2 is movably connected to the middle of the flanging filling part 3. When the driving part 2 moves along the X-axis, it drives both ends of the flanging filling part 3 to expand or contract outward along the Y-axis. When both ends of the flanging filling part 3 expand outward along the Y-axis, it fills the flanging edge on the top cover side. The driving part 2 and the flanging filling part 3 are mounted on the lower base plate of the mold 1. The limiting guide part 4 is fixed to the lower base plate of the mold 1, and it constrains the driving part 2 to move only along the X-axis and the flanging filling part 3 to move only along the Y-axis. Specifically:

[0041] like Figures 1-6 As shown, the drive unit 2 includes: a drive cylinder 21, a connector 22, a drive crossbar 23, and a connecting rod mounting block 24. The drive cylinder 21 is connected to one end of the drive crossbar 23 via the connector 22. The connection method is not limited. For example, one end of the connector 22 is connected to the drive cylinder 21 by a screw connection, and the other end of the connector 22 is connected to the drive crossbar 23 by a tenon and mortise connection. The drive cylinder 21 is used to drive the drive crossbar 23 to move back and forth in the X direction.

[0042] Multiple connecting rod mounting blocks 24 are provided, and their specific number can be flexibly selected according to actual needs. For example, five connecting rod mounting blocks 24 are provided in this embodiment. To ensure the uniformity of force on the drive crossbar 23 and to ensure the processing accuracy of the top cover side flange, multiple connecting rod mounting blocks 24 are evenly connected to the drive crossbar 23. Each connecting rod mounting block 24 has an A hole and a B hole, which are located on both sides of the connecting rod mounting block 24 and are arranged opposite to each other in the Y direction. The connecting rod mounting blocks 24 are fixed to the drive crossbar 23. In this embodiment, the connecting rod mounting blocks 24 are fixed to the drive crossbar 23 by bolts. The A hole of the drive crossbar 23 is movably connected to one side of the flange filling part 3, and the B hole of the drive crossbar 23 is movably connected to the other side of the flange filling part 3.

[0043] like Figures 1-6 As shown, the flanging filling part 3 includes a first flanging filling component 31 and a second flanging filling component 32. The first flanging filling component 31 and the second flanging filling component 32 are mounted on the lower base plate of the mold 1. The first flanging filling component 31 and the second flanging filling component 32 are arranged opposite to each other; a drive crossbar 23 is disposed between the first flanging filling component 31 and the second flanging filling component 32, and the drive crossbar 23 is movably connected to the first flanging filling component 31 and the second flanging filling component 32 respectively through a connecting rod mounting block 24; during the movement of the drive crossbar 23 in the X direction, it can drive the first flanging filling component 31 and the second flanging filling component 32 to expand or retract in the Y direction; when the first flanging component and the second flanging component move in opposite directions, they expand outwards, and when they move towards each other, they retract. The structure of the first flanging filling component 31 and the second flanging filling component 32 will be further described below:

[0044] The first flanging filling assembly 31 includes: a first moving link 311, a first filling punch 313, and a first guide cover plate 314. One end of the first moving link 311 is movably connected to the A hole of the corresponding link mounting block 24 via a connecting pin, and the other end of the first moving link 311 is movably connected to the first filling punch 313 via a connecting pin. The first guide cover plate 314 is fixed on the lower base plate of the mold 1. The first guide cover plate 314 and the first filling punch 313 are arranged in a one-to-one correspondence. A first guide cover plate 314 is respectively provided at the two ends of the first filling punch 313. The first guide cover plate 314 is used to constrain the first filling punch 313 to move only in the Y direction, so as to realize the filling when the top cover side is flanged.

[0045] The second flanging filling assembly 32 includes: a second motion link 321, a second filling punch 322, and a second guide cover plate 323. One end of the second motion link 321 is movably connected to the B hole of the corresponding link mounting block 24 via a connecting pin, and the other end of the second motion link 321 is movably connected to the filling second punch via a connecting pin. The second guide cover plate 323 is fixed on the lower base plate of the mold 1. The second guide cover plate 323 and the second filling punch 322 are arranged in a one-to-one correspondence. A second guide cover plate 323 is respectively arranged at the two ends of the second filling punch 322. The second guide cover plate 323 is used to constrain the second filling punch 322 to move only in the Y direction, so as to realize the filling when the top cover side is flanged.

[0046] like Figure 2 , Figure 7 and Figure 8 As shown, the limiting guide section 4 includes an X-direction limiting block 41 and a Y-direction limiting guide slider assembly 42. The Y-direction limiting guide slider includes a first Y-direction guide slider and a second Y-direction guide slider. The first Y-direction guide slider and the second Y-direction guide slider are arranged opposite to each other and are arranged along the X-direction. The drive crossbar 23 is arranged between the first Y-direction guide slider and the second Y-direction guide slider and is in close contact with the first Y-direction guide slider and the second Y-direction guide slider to ensure that the drive crossbar 23 moves linearly along the X-direction during the movement. The X-direction limiting block 41 is fixed on the lower base plate of the mold 1 and is located at the front end of the stroke of the drive crossbar 23. When the drive crossbar 23 moves forward to the limit position, the drive crossbar 23 abuts against the X-direction limiting block 41. The X-direction limiting block 41 is used to limit the maximum stroke.

[0047] When the production line cycle time increases, the entire flanging and filling device risks bouncing upwards. To reduce this risk, the limiting guide section 4 further includes a Z-direction limiting guide slide assembly 43. Specifically, the Z-direction limiting guide slide assembly 43 includes a first Z-direction guide slide and a second Z-direction guide slide. The first Z-direction guide slide and the second Z-direction guide slide are arranged opposite to each other and are configured with an inverted L-shape. The drive crossbar 23 is located between the first Z-direction guide slide and the second Z-direction guide slide. The upper ends of the first Z-direction guide slide and the second Z-direction guide slide are used to limit the drive crossbar 23 from bouncing in the Z direction. When the drive crossbar 23 bounces upwards, it is limited by the upper ends of the first Z-direction guide slide and the second Z-direction guide slide.

[0048] In this embodiment of the invention, in order to further ensure that the motion trajectory of the drive part 2 is a linear motion in the X direction, a linear concave groove 5 in the X direction is also provided on the bottom plate of the mold 1, and the drive crossbar 23 is disposed in the concave groove 5.

[0049] like Figures 1-9As shown, the working process of the linkage filling device applied in the side flange of the top cover provided in this embodiment of the invention is as follows: The drive cylinder 21 is controlled to move forward along the X direction. During the forward movement of the drive crossbar 23, the first filling punch 313 and the second filling punch 322 are driven to expand outward through the linkage mounting block 24 and the moving connecting rod, thus achieving filling during the flange of the top cover. Then, the robot arm uses a suction cup to pick up the not-yet-fully-formed sheet metal and places it on the mold 1. The top cover is positioned by the positioning pin on the mold 1. At this time, the entire mold 1 begins to close downwards. When the upper mold reaches the bottom, the oblique flange forming on both sides of the top cover is completed. When the upper mold of the mold 1 opens upwards, the drive cylinder 21 is controlled to move backward along the X direction. During the backward movement of the drive crossbar 23, the first filling punch 313 and the second filling punch 322 are driven to retract through the linkage mounting block 24 and the moving connecting rod. At this time, the next robot arm uses a suction cup to remove the flanged top cover part and place it on the next mold.

[0050] The connecting rod filling device for use in the side flange of the top cover provided in this embodiment of the invention has at least the following beneficial effects or advantages:

[0051] The linkage filling device for side flanging of a top cover provided in this embodiment of the invention has a driving part movably connected to the middle of the flanging filling part. When the driving part moves along the X-direction, it drives both ends of the flanging filling part to expand or contract outward along the Y-direction. The driving part and the flanging filling part are set on the lower base plate of the mold; the limiting guide part is fixed on the lower base plate of the mold, and the limiting guide part is used to constrain the driving part to move only along the X-direction and to constrain the flanging filling part to move only along the Y-direction. This linkage filling device for side flanging of a top cover only includes the lower base plate of the mold, the driving part, the flanging filling part, and the limiting guide part. It has a simple structure, reduces the number of standard and non-standard parts, saves material costs, and effectively reduces mold costs; it can also shorten the mold processing, assembly, and debugging time. At the same time, when applied to the side flanging process of the top cover, the symmetrical characteristics of the top cover part itself allow the flanging and shaping forces of the left and right filling punches to be perfectly canceled out, which can ensure the surface forming requirements of the part.

[0052] In the description of this invention, it should be noted that the terms used in the various embodiments, such as "upper," "lower," "front," "rear," "left," and "right," which indicate orientation, are only used to simplify the description of the positional relationships based on the accompanying drawings and do not mean that the components and devices referred to must be operated in accordance with the specific orientations and defined operations, methods, and structures in the specification.

For example, they can refer to fixed connections or detachable connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.
