[0002] Automotive sheet metal is a professional term in the automotive industry, mainly referring to the metal shell of a car. This part is usually made of steel plates and not only bears the important responsibility of protecting the internal structure of the car and the safety of passengers, but is also an important factor in the car's appearance. In addition, as the main carrier of aerodynamic drag, the design of automotive sheet metal parts plays a crucial role in reducing wind resistance, reducing noise, and improving driving stability. In the development history of the automotive industry, with the continuous progress of materials science and manufacturing processes, the performance and quality of automotive sheet metal parts have also been significantly improved.

[0003] In the existing technology, during the assembly process of automotive sheet metal, it is often necessary to assemble some long workpieces. This process requires a robotic arm that can clamp and fix them. However, the existing assembly robotic arms are difficult to meet the clamping and fixing operation of long workpieces. Utility Model Content

[0005] Existing assembly robotic arms are insufficient for clamping and fixing long workpieces.

[0006] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0007] A new energy vehicle sheet metal assembly robotic arm includes a fixedly connected mounting base and a connecting base. The top of the mounting base is fixedly connected to a matching upper guard plate and a lower guard plate. A drive mechanism is fixedly connected to the top of the mounting base. Limiting shafts are provided on both sides of the bottom of the mounting base. A drive arm is movably sleeved at both ends of the limiting shafts. A fixing plate is fixedly connected to the bottom end of the drive arm. A limiting layer is fixedly connected to the inner side of the fixing plate.

[0008] Furthermore, the two ends of the connecting seat are set with downward bends, and there are two sets of them, which are fixedly connected to the two ends of the mounting seat. There are also two sets of limiting shafts, and their outer ends are fixedly connected to the bottom bend position of the connecting seat.

[0009] Furthermore, the connecting cross plate is rectangular in shape and located below the limiting axis.

[0010] Furthermore, two sets of limit seats are arranged horizontally in an "H" shape, and their outer ends are connected by a shaft and a connecting block in a rotating manner. Two sets of connecting blocks are arranged vertically in a "Y" shape, in pairs, and the outer ends of the connecting blocks are connected by a shaft and a drive arm in a movable clamping manner.

[0011] Furthermore, the drive arm is arranged in a "Z" shape, with the top end and the limiting shaft movably connected, the middle section and the connecting block movably connected, the fixing plate being a rectangular plate, and the limiting layer being a rectangular rubber layer with a "V" shaped concave surface.

[0012] Furthermore, the upper guard plate is L-shaped and fits the top of the mounting base. Its bottom end and the lower guard plate are connected by a rotating shaft, and a drive motor is installed at the outer end of the shaft.

[0013] Furthermore, the lower guard plate is L-shaped and located below the drive arm.

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] See Figure 1-3 As shown, a new energy vehicle sheet metal assembly robotic arm includes a fixedly connected mounting base 1 and a connecting base 2. The top of the mounting base 1 is fixedly connected to a matching upper guard plate 12 and a lower guard plate 13. The top of the mounting base 1 is fixedly connected to a drive mechanism 7. Limiting shafts 9 are provided on both sides of the bottom of the mounting base 1. Drive arms 3 are movably sleeved at both ends of the limiting shafts 9. The bottom end of the drive arm 3 is fixedly connected to a fixing plate 4. A limiting layer 11 is fixedly connected to the inner side of the fixing plate 4. The bottom end of the drive mechanism 7 is provided with a drive rod 10. The bottom end of the drive rod 10 is fixedly connected to a connecting horizontal plate 8. Limiting seats 6 are fixedly connected to both ends of the connecting horizontal plate 8. Connecting blocks 5 are movably connected to both ends of the limiting seats 6. The connecting blocks 5 are also movably connected to the drive arm 3.

[0026] In this embodiment of the utility model, the connecting seat 2 has two sets of downward angled ends, which are fixedly connected to the two ends of the mounting seat 1. The limiting shaft 9 has two sets, and its outer end is fixedly connected to the bottom angled end of the connecting seat 2. The connecting horizontal plate 8 is rectangular in shape and located below the limiting shaft 9. The connecting seat 2 achieves the effect of limiting the installation of the limiting shaft 9, the limiting shaft 9 provides support and guidance for the drive arm 3, and the connecting horizontal plate 8 drives the limiting seat 6 to rise and fall.

[0027] Two sets of limiting seats 6 are arranged horizontally in an "H" shape. Their outer ends are connected to the connecting blocks 5 by a shaft and a rotating mechanism. Two sets of connecting blocks 5 are arranged vertically in a "Y" shape, in pairs. The outer ends of the connecting blocks 5 are connected to the drive arm 3 by a shaft and a rotating mechanism. The drive arm 3 is arranged in a "Z" shape. Its top end is movably connected to the limiting shaft 9, and its middle section is movably connected to the connecting blocks 5. The fixing plate 4 is a rectangular plate, and the limiting layer 11 is a rectangular rubber layer with a "V" shaped concave surface. The limiting seats 6 can drive the connecting blocks 5 connected at both ends to rotate and adjust their angle. The connecting blocks 5 can drive the drive arm 3 to rotate and adjust as a whole. The drive arm 3 can drive the fixing plate 4 and the limiting layer 11 to adjust inward and outward. The limiting layer 11 can limit and clamp the workpiece to its outer length.

[0028] When clamping and assembling the outer workpiece, the drive mechanism 7 and drive rod 10 rise and fall vertically, causing the connecting horizontal plate 8 to descend below the mounting base 1. The descent of the connecting horizontal plate 8, under the action of the limiting seat 6, causes the connecting blocks 5 at both ends of the limiting seat 6 to flip and adjust. The flipping and adjustment of the connecting blocks 5 pushes the drive arm 3 to flip and adjust inward and outward as a whole, thereby causing the limiting layer 11 to move inward and outward, clamping and supporting the outer workpiece.

[0029] The upper guard plate 12 is L-shaped and fits the top of the mounting base 1. Its bottom end and the lower guard plate 13 are connected by a rotating shaft. A drive motor is installed at the outer end of the shaft. The lower guard plate 13 is L-shaped and located below the drive arm 3. The upper guard plate 12 and the lower guard plate 13 are movably connected to achieve the effect of protecting the long workpiece in the external clamping state from the bottom position.

[0030] After clamping the long workpiece, the lower guard plate 13 flips inward, changing from a vertical to a horizontal state, protecting the long workpiece from below and preventing it from falling.

[0031] In this device, the drive mechanism 7 is a hydraulic drive mechanism, specifically model BOSCHREXROTH (HMI series compact hydraulic mechanism); the drive motor is a servo motor mechanism, MINASA6 series (such as MHMF082L1U2M).

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
