DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0020] Example:

[0021] Reference Figures 1-3The utility model discloses an automatic bending mechanism for the end of automobile arc cover plate, which comprises a base plate 1, a base 2 and a bending assembly arranged on the base plate 1, a positioning column 4 rotatably connected to the base 2, a rotating mechanism 5 fixedly connected to the lower part of the base 2, a rotating shaft of the rotating mechanism 5 fixedly connected to the positioning column 4, a deflection-preventing groove 401 and a bending groove 402 arranged on the positioning column 4, and a bending assembly 3 comprising a support 301, a bending cylinder 302, a cutter holder 303 and a bending cutter 304, wherein the cutter holder 303 is fixedly connected to the piston rod of the bending cylinder 302, and the bending cutter 304 is detachably connected to the cutter holder 303.

[0022] The rotating mechanism 5 is a servo motor, and the multiple bending grooves 402 on the outer wall of the positioning column 4 can adapt to the bending treatment of different points of the automobile arc cover plate. The multiple suction holes 403 formed in the side wall of the positioning column 4 can further suck and fix the automobile arc cover plate after the automobile arc cover plate is positioned and placed, so as to prevent the automobile arc cover plate from deflecting during the bending.

[0023] When the bending treatment of the automobile arc cover plate is completed, the piston rod of an unloading cylinder 6 is extended, and a jacking disc seat 7 will jacking lift the automobile arc cover plate so that the upper end of the automobile arc cover plate extends out of the positioning column 4, thereby avoiding that the bent section adheres to the original bending position and facilitating unloading. The jacking disc seat 7 is slidably connected to the positioning column 4, and the positioning column 4 can guide the lifting and sliding of the jacking disc seat 7.

[0024] The bending cylinder 302 fixedly connected to the support 301 can drive the cutter holder 303 and the bending cutter 304 to perform a bending action through the extension and retraction of the piston rod thereof.

[0025] In the utility model, the automobile arc cover plate is placed on the jacking disc seat 7 along the deflection-preventing groove 401 and the positioning column 4 during the machining, then the inner wall of the automobile arc cover plate is fixedly sucked through the suction holes 403, then the positioning column 4 is driven to rotate by the rotating mechanism 5, so that the bending groove 402 corresponding to one end of the automobile arc cover plate is rotated to the opposite position of the bending assembly, the piston rod of the bending cylinder 302 is extended, and the bending cutter 304 performs a bending treatment on the end of the automobile arc cover plate. After the bending of one end is completed, the positioning column 4 is reversely rotated by the rotating mechanism 5, so that the bending groove 402 corresponding to the other end of the automobile arc cover plate is rotated to the opposite position of the bending assembly, and the bending treatment is continuously performed. After the bending treatment of both ends is completed, the piston rod of the unloading cylinder 6 is extended, and the jacking disc seat 7 jacking lifts the automobile arc cover plate to unload the automobile arc cover plate after the jacking, thereby completing the machining.

[0026] The above examples are used to further illustrate the utility model, but the utility model is not limited to these specific embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be understood as being within the protection scope of the utility model.
