[0002] In modern manufacturing, five-axis machining centers play a crucial role in numerous fields such as aerospace, automotive manufacturing, and mold making due to their superior machining capabilities. They can achieve high-precision machining of complex curved surfaces, meeting the ever-increasing demands for product quality and design complexity. However, in five-axis machining, the part machining fixture, as a vital component for fixing and positioning the workpiece, directly impacts machining efficiency and quality. Traditional five-axis machining center part machining fixtures have revealed many problems in practical applications. When dealing with parts requiring multi-faceted machining, manual face-changing operations are often relied upon. This process is not only time-consuming but also prone to workpiece positioning deviations due to the instability of manual operation, thus affecting machining accuracy.

[0003] Therefore, this application provides a five-axis machining center part machining fixture. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] like Figures 1 to 4 As shown, this application provides a five-axis machining center part machining fixture, including:

[0025] The clamping mechanism 100 includes a base 10, an A-axis flipping mechanism 20, a C-axis rotating mechanism 30, a clamping mechanism 40, and a rotating disk 32. Support frame 11 and support frame 2 12 are fixedly installed on the left and right sides of the upper surface of the base 10, respectively. The A-axis flipping mechanism 20 is located between support frame 11 and support frame 2 12. The C-axis rotating mechanism 30 is located at the upper end of the A-axis flipping mechanism 20. The clamping mechanism 40 is located at the upper end of the C-axis rotating mechanism 30. The control panel 13 is fixedly installed on one side of support frame 2 12. The rotating disk 32 is located at the upper end of the A-axis flipping mechanism 20. The flipping mechanism 50 includes a second slide groove 51 disposed on one side of the upper surface of the rotating disk 32, a third slide groove 52 disposed on the other side of the rotating disk 32, a first cylinder 53 fixedly installed on one side of the upper surface of the rotating disk 32, and a second cylinder 54 fixedly installed on the other side of the upper surface of the rotating disk 32. A flipping plate 55 is hinged inside the second slide groove 51. The flipping plate 55 has an "L" shaped structure. The end of the output shaft of the first cylinder 53 is in contact with one side of the flipping plate 55. A wedge-shaped push block 56 is slidably connected inside the third slide groove 52. The end of the output shaft of the second cylinder 54 is fixedly connected to one side of the wedge-shaped push block 56.

[0026] After adopting the above technical solution, by setting a flipping mechanism 50 on the upper surface of the rotary disk 32, when it is necessary to flip the workpiece, the wedge-shaped pusher 56 is pushed by the cylinder 2 54 to move along the slide groove 3 52. During the movement of the slide groove 3 52, it lifts one side of the workpiece. Since one end of the workpiece is stuck by the flipping plate 55, when the workpiece is lifted, the flipping plate 55 is forced to flip the workpiece backward to achieve automatic flipping, which greatly improves the working efficiency of the equipment.

[0027] It should be noted that the workpiece to be processed is placed between the two clamping plates 44. Motor 3 42 drives the lead screw 43 to rotate. During the rotation of the lead screw 43, the two clamping plates 44 move towards each other along the slide groove 41, thus clamping the workpiece. After the workpiece is clamped, the control panel 13 drives motor 1 22 to work. Motor 1 22, in conjunction with the transmission belt 24, rotates the transmission disk 23, thereby driving the rotating seat 21 to rotate along the A-axis. Simultaneously, the control panel 13 drives motor 2 31 to work, which in turn drives the rotating disk 32 to rotate, allowing the fixture to rotate along the C-axis. When the workpiece needs to be flipped, the two clamping plates 44 are first moved outward by motor 3 42, so that the clamping plates 44 no longer clamp the workpiece. At this time, cylinder 2 54 works to push the wedge-shaped push block 56 along the slide groove 3 52 toward the workpiece. The force-bearing end of the workpiece enters the interior of the flipping plate 55. At this time, cylinder 1 53 retracts so that its end no longer contacts the flipping plate 55. At this time, cylinder 2 54 continues to push to lift one side of the workpiece. The workpiece is flipped with the cooperation of the wedge-shaped push block 56 and the flipping plate 55. After the workpiece is flipped, the two clamping plates 44 are moved toward each other by motor 3 42, so as to clamp the flipped workpiece.

[0028] In an optional embodiment, the A-axis flipping mechanism 20 includes a rotating seat 21 rotatably connected between a first support frame 11 and a second support frame 12. A first motor 22 is fixedly installed on one side of the second support frame 12, and a transmission disk 23 is fixedly installed on one side of the rotating seat 21. A transmission belt 24 is provided between the first motor 22 and the transmission disk 23. When the first motor 22 is working, the transmission disk 23 is rotated by the first motor 22 in conjunction with the transmission belt 24, thereby driving the rotating seat 21 to rotate between the second support frame 12 and the first support frame 11, so that the equipment has the function of A-axis rotation.

[0029] In an optional embodiment, the C-axis rotation mechanism 30 includes a second motor 31 fixedly installed inside the rotating base 21. The output shaft of the second motor 31 is fixedly connected to the bottom of the rotating disk 32. The operation of the second motor 31 drives the rotating disk 32 to rotate, thereby enabling the device to rotate along the C-axis.

[0030] In an optional embodiment, the clamping mechanism 40 includes a slide groove 41 formed on the upper surface of the rotary disk 32 and a motor 42 fixedly installed on one side of the rotary disk 32. A lead screw 43 is fixedly installed at the end of the output shaft of the motor 42. Clamping plates 44 are slidably connected to both sides inside the slide groove 41. The lead screw 43 is threadedly connected to the lower ends of the two clamping plates 44. The motor 42 drives the lead screw 43 to rotate. During the rotation of the lead screw 43, the two clamping plates 44 move towards each other along the slide groove 41, thereby clamping the workpiece through the clamping plates 44.

[0031] In one alternative embodiment, the two threads extending from the middle of the lead screw 43 to both sides have opposite directions of rotation, which can drive the two clamping plates 44 to move simultaneously when the lead screw 43 rotates.

[0032] In one optional embodiment, the control panel 13 is provided with control buttons and a display screen on the outside, and the control panel 13 is provided with a control circuit board and a battery inside. The control panel 13 is electrically connected to motor 22, motor 31, cylinder 53 and cylinder 54. The control panel 13 controls the start and stop of motor 22, motor 31, cylinder 53 and cylinder 54, thereby realizing automatic clamping and flipping.

[0033] In an optional embodiment, friction grooves are provided on the opposing sides of the two clamping plates 44 to improve the clamping force of the clamping plates 44.
