[0038] To make the purpose, technical solution, and advantages of the present technical solution clearer and more understandable, the present technical solution will be further described in detail below in conjunction with specific embodiments. It should be understood that these descriptions are exemplary and not intended to limit the scope of the present technical solution.

[0039] To solve the problems in the prior art that the top cover pressing mechanism only relies on the profiled surface obtained by machining for fitting, resulting in inaccurate fitting and unsatisfactory fitting effect, as Figures 1-3 shown, this embodiment proposes a multi-directional flexible self-adaptive pressing mechanism 20 for the top cover. As Figure 1 shown, specifically, the multi-directional flexible self-adaptive pressing mechanism 20 for the top cover includes two main mechanisms: a flip drive mechanism 10 and a self-adaptive pressing mechanism 20. Among them, the function of the self-adaptive pressing mechanism 20 is to complete the flexible pressing of the top cover through self-adaptive actions. The flip drive mechanism 10 is a drive mechanism for driving the self-adaptive pressing mechanism 20 to flip, and its function is to drive the self-adaptive pressing mechanism 20 to flip to achieve the pressing action.

[0040] In this embodiment, the flipping drive mechanism 10 includes a base beam 12 which is horizontally arranged. U-shaped grooves are opened at both the first end and the second end of the base beam 12. The flipping drive mechanism 10 includes a main body and an extending end of a linear drive device 13. The root of the main body of the linear drive device 13 is hinged to the first end of the base beam 12 to achieve free rotation. The lower end of the rotating beam 14 is inserted into the U-shaped groove at the second end of the base beam 12 and is hinged to the second end of the base beam 12 through a first rotating shaft 15. The upper end of the rotating beam 14 is hinged to the extending end of the linear drive device 13 through a second rotating shaft 16.

[0041] The above linear drive device 13 is preferably a cylinder. In other embodiments, the linear drive device 13 can also adopt an electric cylinder or other linear drive devices, or a composite linear drive device.

[0042] In the above flipping drive mechanism 10, since a triangular hinged structure is formed by the linear drive device 13, the base beam 12 and the rotating beam 14, when the extending end of the linear drive device 13 expands and contracts, the rotating beam 14 can be driven by the linear drive device 13 to flip by a small and controllable angle.

[0043] As Figure 1 and Figure 3 shown, limit blocks 17 with press-fitting are provided at the hinged joints of the base beam 12 and the rotating beam 14. The limit blocks 17 are used to limit the extreme rotation position of the rotating beam 14 to prevent the flipping drive mechanism 10 from driving the adaptive pressing mechanism 20 to flip excessively and causing plastic deformation of the top cover.

[0044] An installation plate 11 is installed at the end face of the second end of the base beam 12. The main extension surface of the installation plate 11 is perpendicular to the main extension direction of the base beam 12. The function of the installation plate 11 is to integrally install the multi-directional flexible adaptive pressing mechanism 20 of this top cover on an external installation base.

[0045] The structure of the adaptive pressing mechanism 20 includes a base 21; a floating connection mechanism, including an installation base end and a floating connection end. The floating connection mechanism is installed on the base 21 through the installation base end; a pressing block 26 which is installed at the floating connection mechanism and the floating connection end. In the multi-directional flexible adaptive pressing mechanism 20 of the top cover proposed by the present utility model, since the floating connection mechanism is used to connect the base 21 and the pressing block 26, the floating connection mechanism can perform adaptive actions according to the shape of the contacted top cover surface, solving the problem of inaccurate fitting between the machined surface and the top cover surface.

[0046] Specifically, the floating connection mechanism includes a mounting base 22 fixedly connected to the base 21; a Y-direction rotation pin shaft 23 fixedly connected to the mounting base 22; a connecting seat 24 rotatably connected to the Y-direction rotation pin shaft 23; and a pressing block 26 connected to the connecting seat 24. An X-direction rotation pin shaft 25 is fixedly connected to the connecting seat 24; the pressing block 26 is rotatably connected to the X-direction rotation pin shaft 25; the axis of the X-direction rotation pin shaft 25 and the axis of the Y-direction rotation pin shaft 23 are skew and perpendicular to each other.

[0047] Due to the cooperation effect of the Y-direction rotation pin shaft 23 and the X-direction rotation pin shaft 25, the pressing block 26 in this embodiment can achieve free movement in a small range in the Y direction and the X direction. Therefore, when the pressing block 26 contacts the cover plate, the pressing surface of the pressing block 26, that is, the inclined surface at the bottom of the pressing block 26 in this embodiment, can rotate in a small range left and right, front and back to achieve the effect of multi-directional flexible adaptive pressing.

[0048] Preferably, the base 21 is fixedly connected to the rotating beam 14, and the base 21 is installed on the side of the rotating beam 14, and its function is to avoid the position of the limiting block 17.

[0049] There are two sets of the floating connection mechanism and the pressing block 26, and the two sets of the floating connection mechanism and the pressing block 26 are adjacent and arranged in parallel. By using the two sets of the above-mentioned floating connection mechanism and the pressing block 26, the multi-directional flexible adaptive pressing mechanism 20 of the top cover can increase the pressing contact area between the surface and the sheet metal, and at the same time is suitable for the pressing work at non-planar places.

[0050] In addition, this embodiment also proposes a vehicle processing device, which uses the above-mentioned multi-directional flexible adaptive pressing mechanism of the top cover and also inherits the advantages and effects of the above-mentioned multi-directional flexible adaptive pressing mechanism of the top cover.

[0051] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the technical content, many changes can be made in the specific implementation manner and application scope. As long as these changes do not depart from the concept of the present invention, they all belong to the protection scope of this patent.
