Technical Field
[0001] This utility model belongs to the field of automotive parts technology, specifically a two-axis flipping and cutting mechanism. Background Technology
[0002] In the field of automotive body component assembly, with the booming development of the automotive industry, increasingly higher demands are being placed on the processing precision and production efficiency of components. The assembly of body components involves numerous steps, among which the cutting process, as a crucial preliminary step, directly affects the assembly quality of subsequent components and the overall production schedule of the automobile. During the production of automotive body components, it is often necessary to process workpieces at different angles and switch between different workstations. For example, when cutting parts with complex shapes or requiring multi-faceted processing, the workpiece needs to be interchanged at workstations in the horizontal direction and rotated in the vertical plane to meet the requirements of different processing steps.
[0003] Currently, existing cutting mechanisms on the market have many shortcomings when handling workpieces that require flipping and station switching. Most traditional cutting mechanisms can only achieve single horizontal movement or simple angle adjustment, making it difficult to simultaneously achieve precise horizontal station interchange and vertical rotation. This leads to the need for frequent workpiece repositioning and adjustment during processing, which not only increases operational complexity and reduces production efficiency, but may also affect the workpiece's processing accuracy due to positioning errors.

[0006] The fixed shaft is rigidly connected to the fixed floor.
[0007] The rotary cylinder is fixed to the fixed floor, and its rotating end drives the rotary support.
[0008] The rotating support has a first rotating shaft and a second rotating shaft symmetrically arranged on both sides. Pneumatic grippers are mounted on the first rotating shaft and the second rotating shaft, respectively.

[0013] Both bevel gear one and bevel gear two are meshed with bevel gear three. The pneumatic gripper one and pneumatic gripper two rotate vertically around the support shaft one and the support shaft two through bevel gear meshing.
[0014] Both the first and second rotating shafts of the bracket are movably installed on both sides inside the rotating bracket.
[0015] Preferably, the end of the pneumatic gripper one is slidably connected to two sets of symmetrically arranged rubber pad grippers one, and the end of the pneumatic gripper two is slidably connected to two sets of symmetrically arranged rubber pad grippers two, and the pneumatic gripper one, pneumatic gripper two and the rubber pad grippers one, rubber pad grippers two are coaxially arranged.
[0016] Preferably, the retaining ring and the retaining shaft are interference-fitted;

[0018] Preferably, the rotating bracket has a U-shaped symmetrical structure, with its rotation center coinciding with the axis of the fixed shaft, and the first and second rotating shafts of the bracket are equidistantly distributed with the rotation center as the axis of symmetry.
[0019] Preferably, the first pneumatic gripper is connected to the support shaft with one key, and the second pneumatic gripper is connected to the support shaft with two keys, so as to realize torque transmission without slippage.
[0020] Preferably, the horizontal rotation and the vertical rotation have the same angular velocity, and the pneumatic gripper one and the pneumatic gripper two rotate in opposite directions.

[0022] Compared with the prior art, the beneficial effects of this utility model are:
[0023] (1) In this utility model, the rotating support is driven to rotate horizontally by a rotary cylinder by 180°. The pneumatic gripper one and pneumatic gripper two achieve the exchange of work positions on the horizontal plane. At the same time, each rotates 180° around the support axis in the vertical plane.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0030] Example
[0031] Please see Figure 1 - Figure 3 This application provides a two-axis flipping and cutting mechanism, including a fixed base 1, a rotary cylinder 2, a rotary support 3, and a fixed shaft 6;
[0032] The fixed shaft 6 is rigidly connected to the fixed base plate 1;
[0033] The rotary cylinder 2 is fixed to the fixed floor 1, and its rotating end drives the rotary bracket 3.
[0034] The rotating bracket 3 has a symmetrically arranged bracket shaft 13 and bracket shaft 2 14 on both sides. At the same time, pneumatic grippers 1 4 and 2 7 are respectively installed on the bracket shaft 13 and bracket shaft 2 14.
[0035] The bevel gear 12 is coaxially fixed on the fixed shaft 6 via the fixing ring 5;
[0036] The bracket shaft 13 is coaxially fixedly connected to the bevel gear 9, and the bracket shaft 2 14 is coaxially fixedly connected to the bevel gear 2 11.
[0037] When the rotary cylinder 2 drives the rotary support 3 to rotate horizontally, it enables the pneumatic gripper 4 and the pneumatic gripper 7 to rotate vertically.
[0038] More specifically: the rotary cylinder 2 is mounted on the fixed floor 1, and its rotary output end is connected to the rotary bracket 3 to drive the rotary bracket 3 to rotate in the horizontal plane;
[0039] When the rotary cylinder 2 drives the rotary support 3 to rotate horizontally, the first bevel gear 9 and the second bevel gear 11 revolve around the third bevel gear 12. At the same time, the first bevel gear 9 and the second bevel gear 11 mesh with the third bevel gear 12 and rotate on their own, thereby driving the pneumatic gripper 4 and the pneumatic gripper 7 to rotate in the vertical plane around their respective support axes.
[0040] In this embodiment, preferably, the rotating bracket 3 is driven to rotate horizontally by the rotating cylinder 2, and the output shaft of the rotating cylinder 2 is rigidly connected to the rotating bracket 3 through a flange.
[0041] Bevel gear 19 and bevel gear 21 are both meshed with bevel gear 312. Pneumatic gripper 14 and pneumatic gripper 27 rotate vertically around bracket shaft 13 and bracket shaft 214 through bevel gear meshing.
[0042] Both the first bracket shaft 13 and the second bracket shaft 14 are movably installed on both sides inside the rotating bracket 3.
[0043] More specifically: when the rotary cylinder 2 drives the rotary support 3 to rotate horizontally by 180°, the pneumatic gripper 4 and the pneumatic gripper 7 exchange positions on the horizontal plane, and at the same time, they rotate 180° in the vertical plane around the axes of the support shaft 13 and the support shaft 24.
[0044] It should be noted that the retaining ring 5 axially fixes the bevel gear 3 12 to the fixed shaft 6 and prevents the bevel gear 3 12 from rotating relative to the fixed shaft 6;
[0045] Rotary cylinder 2 is a pneumatic rotary actuator with a rotation angle of 180°.
[0046] In this embodiment, preferably, the end of the pneumatic gripper 4 is slidably connected to two sets of symmetrically arranged rubber pad grippers 8, and the end of the pneumatic gripper 7 is slidably connected to two sets of symmetrically arranged rubber pad grippers 10. The pneumatic gripper 4, the pneumatic gripper 7 and the rubber pad grippers 8 and 10 are coaxially arranged.
[0047] In this embodiment, preferably, the fixing ring 5 and the fixing shaft 6 are interference-fitted;
[0048] The number of teeth is the same for bevel gear 1 (9), bevel gear 2 (11), and bevel gear 3 (12).
[0049] It should be noted that the bevel gear 9, bevel gear 11, and bevel gear 312 have the same number of teeth, causing bevel gear 9 and bevel gear 11 to rotate at the same speed.
[0050] In this embodiment, preferably, the rotating bracket 3 has a U-shaped symmetrical structure, with its rotation center coinciding with the axis of the fixed shaft 6, and the first rotating shaft 13 and the second rotating shaft 14 of the bracket are equidistantly distributed with the rotation center as the axis of symmetry.
[0051] In this embodiment, preferably, the pneumatic gripper 4 is keyed to the support shaft 13, and the pneumatic gripper 7 is keyed to the support shaft 14, so as to achieve torque transmission without slippage.
[0052] In this embodiment, preferably, the angular velocities of horizontal rotation and vertical rotation are the same, and the rotation directions of pneumatic gripper 4 and pneumatic gripper 7 are opposite.
[0053] In this embodiment, preferably, the third bevel gear 12 is located at the center of the meshing plane of the first bevel gear 9 and the second bevel gear 11, and the axes of the three intersect on the same horizontal plane.
[0054] During implementation, after the two sets of rubber pad grippers 10 and 8 clamp the workpiece in the middle, a rotary cylinder 2 is set up. The output end of the rotary cylinder 2 drives the rotary support 3 to rotate horizontally 180° around the fixed axis 6. When the rotary support 3 rotates, the bevel gear 12 remains stationary. The bevel gear 9 rolls along the tooth surface of the bevel gear 12, forcing the support shaft 13 to rotate counterclockwise around its own axis. The bevel gear 11 rolls in the opposite direction along the tooth surface of the bevel gear 12, forcing the support shaft 14 to rotate clockwise around its own axis. This causes the rotary cylinder 2 to drive the pneumatic gripper 7 and the pneumatic gripper 4 to rotate 180° horizontally by half, realizing the workstation rotation. At the same time, the pneumatic gripper 7 and the pneumatic gripper 4 tumble vertically 180° around the rotary support 3 by the bevel gear 11 and the bevel gear 9.
[0055] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
