[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1: Reference Figure 1-5 A flip fixture for lathe processing shown in 9 includes a lathe, an end plate 1, and a flip plate 2. End plates 1 are provided at both ends of the flip plate 2, and the whole is in an I-shape. The rotating shaft of the lathe is connected to the end plate 1, and the motor inside the lathe drives the end plate 1 to rotate through the rotating shaft, thereby realizing the control of multi-angle rotation of the workpiece.

[0027] A pressing mechanism and a positioning mechanism for limiting the workpiece are provided on the flip plate 2, and the notch portion of the flip plate 2 is plugged (bolted) with a mold corresponding to the workpiece during processing. The mold and the workpiece are a convex part and a concave part respectively. After the mold and the workpiece are installed respectively, the pressing mechanism and the positioning mechanism can be started to limit the workpiece.

[0028] The telescopic cylinder 3 is installed on the limit plate 4, and the limit plate 4 is installed on the flip plate 2. After the workpiece is placed on the mold, the telescopic cylinder 3 is started and its telescopic end slides in the limit groove 51 at the bottom of the pressing block 5 through the limit head 31, thereby controlling the flipping angle of the pressing block 5 on the limit plate 4, thereby realizing the limitation of the workpiece from the top.

[0029] The bottom surface of the upper limit plate 41 is provided with an end block 42 which is hinged to the pressing block 5 through a hinged connecting plate 43. The flexibility of the downward pressing mechanism and the cooperation between the limit head 31 and the limit groove 51 can avoid structural problems of the above structure.

[0030] Positioning mechanism: Mounting plates 6 are hoisted on the left and right sides of the notch (the bottom surface of the flip plate 2), and one end surface of the mounting plate 6 is used to fix the motor 7. The driving shaft of the motor 7 passes through the mounting plate 6 and is connected to the No. 1 positioning piece 8, so that when the driving motor 7 rotates, the No. 1 positioning piece 8 is controlled to flip and the workpiece is limited to the outward end. In order to adapt to a variety of different workpieces, a storage groove 81 is provided at the inward end of the No. 1 positioning piece 8. The rectangular storage groove 81 is adapted to the telescopic frame 83. Therefore, the adjustment hole 82 provided on the No. 1 positioning piece 8 corresponds to the adjustment screw hole 84 on the telescopic frame 83. Therefore, when the handle 85 rotates in the adjustment hole 82, it meshes with the adjustment screw hole 84 through the threaded section. Under the limitation of the storage groove 81, the telescopic frame 83 is controlled to extend outward, so as to adapt to a variety of different specifications of workpieces.

[0031] Working principle of embodiment 1: through the notch position of the flip plate 2, a group of molds are fixed by bolts. During processing, the workpiece is inserted into the mold to achieve the first step of fixing (the mold is a convex part, and the workpiece is a concave part). Then, the motor 7 arranged on the mounting plate 6 is started. The motor 7 drives the positioning mechanism connected to the drive shaft to rotate, so that the No. 1 positioning member 8 is flipped upward to limit the workpiece (to prevent the workpiece from falling when the lathe drives the end plate 1 and the flip plate 2 to flip). Before limiting, the handle 85 on the No. 1 positioning member 8 can be rotated according to the specifications of the workpiece. The handle 85 rotates on the adjustment hole 82, and the threaded section provided thereon cooperates with the adjustment screw hole 84 on the telescopic frame 83. Under the limitation of the storage groove 81, the telescopic frame 83 is controlled to extend outward to resist the outward end of the workpiece to complete the use of the positioning mechanism; then, according to the specifications of the workpiece, The top screw on the upper limit plate 41 is loosened to release the limit of the limit plate 4 and the flip plate 2, so that the limit plate 4 can move in the slide groove 21 and the slide hole 22. After the position adjustment is completed, the top screw is tightened again to fix the position of the limit plate 4. Then the telescopic cylinder 3 is started, and the telescopic end of the telescopic cylinder 3 passes through the limit head 31 provided on the top, which slides in the limit groove 51 at the bottom of the pressure block 5, so that the rear end of the pressure block 5 is lifted and the front end is pressed down (the end block 42 provided at the end of the upper limit plate 41 is connected to the pressure block 5 through the connecting plate 43, and the two ends of the connecting plate 43 are hinged to improve the freedom of the pressure block, and the cooperation between the lower limit plate 44 and the upper limit plate 41 fixes the position of the telescopic cylinder 3 to prevent it from falling off from the slide groove 21 and the slide hole 22), realizes the downward pressure on the top of the workpiece, and cooperates with the positioning mechanism to realize fixation in two directions, thereby preventing the workpiece from falling off during the processing.

[0032] Embodiment 2: The difference between this embodiment and embodiment 1 is that:

[0033] refer to Figure 6-9, Positioning mechanism: The No. 2 positioning piece 9 is connected to the driving shaft of the motor 7, and the rotation angle of the No. 2 positioning piece 9 is controlled by the rotation of the motor 7, and the No. 2 positioning piece 9 is L-shaped, and the through hole 91 on the No. 2 positioning piece 9 corresponds to the through hole 93 on the adjusting block 92. The through hole 93 and the through hole 91 are connected in series through an adjusting rod 94. In order to fix the angle between the No. 2 positioning piece 9 and the adjusting block 92, the nut 95 threadedly connected at the bottom of the adjusting rod 94 cooperates with each other to achieve the above purpose, and the spring 96 mounted on the adjusting rod 94 achieves the purpose of pre-tightening during the rotation and upward movement of the nut 95.

[0034] Working principle of Example 2: By rotating the adjusting rod 94 and the nut 95, the current state of the No. 2 positioning member 9 and the adjusting block 92 is released. Then, according to the specifications of the workpiece, the angle between the No. 2 positioning member 9 and the adjusting block 92 is determined, and the nut 95 is rotated again to make the nut 95 rotate on the adjusting rod 94, squeezing the spring 96 while squeezing the No. 2 positioning member 9 and the adjusting block 92 to achieve angle fixing and adapt the workpiece.
