In addition, the water receiving box 4 is provided with a drain hole 41 at the bottom, which facilitates the discharge of cutting liquid. The size of the water receiving box 4 is larger than that of the temporary storage table 3, so as to ensure that the liquid on the temporary storage table 3 can be completely received.

[0031] II. Rotator 1

[0032] The rotator 1 is fixedly installed on the side of the temporary storage table 3, and the output end thereof is connected with the reversing claw 2 through the swing arm 21. The rotator 1 comprises a linear drive 11, a rack 12 and a gear 13. The rotator 1 comprises the linear drive 11, the rack 12 and the gear 13, the linear drive 11 is a cylinder in this embodiment, the bottom of the linear drive 11 is fixed on the base 14 provided, the base 14 is fixed on the support frame 10 through bolts, and the support seat 15 is further fixed on the shell of the linear drive 11. The rack 12 is vertically and slidingly connected on the support seat 15, and the gear 13 is rotatably connected on the support seat 15.

[0033] The linear drive 11 drives the linear movement of the rack 12, the rack 12 is engaged with the gear 13, the gear 13 is used for self-rotation under the driving of the rack 12, and the swing arm 21 is fixedly connected with the gear 13. The swing arm 21 is fixedly provided with a baffle 22, the baffle 22 is located between the reversing claw 2 and the gear 13, and the projection area of the gear 13 and the rack 12 to the reversing claw 2 completely falls in the projection area of the baffle 22 to the reversing claw 2.

[0034] The gear 13 is a fan gear 13, the part without teeth of the fan gear 13 is integrally formed with a connecting part, the connecting part is fixedly connected with the swing arm 21, the structural stability and transmission efficiency are ensured, and the swing arm 21 is located at the eccentric position of the gear 13. The reversing claw 2 is fixedly arranged at the free end of the swing arm 21, and is used for clamping or releasing the workpiece 40. In this embodiment, the reversing claw 2 is used for clamping the shaft segment of the hub bearing. Specifically, the reversing claw 2 in this embodiment can adopt the unloading claw in the patent with the publication number CN118143721A.

[0035] In order to conveniently adjust the swing position of the swing arm 21, facilitate the cooperation between the workpiece taking manipulator and the reversing claw 2, at least two strip-shaped holes 101 are arranged on the support frame 10, and a plurality of mounting holes are formed on the base 14. After the mounting holes and the strip-shaped holes 101 are aligned, the locking of the base 14 and the support frame 10 can be realized through bolts and nuts, so that the position of the base 14 on the support frame 10 can be adjusted, that is, the overall position of the rotator 1 and the swing arm 21 can be finely adjusted.

[0036] The rotator 1 drives the linear movement of the rack 12 through the linear drive 11, so that the gear 13 self-rotates under the engagement of the rack 12, thereby driving the swing arm 21 to swing. After the swing arm 21 swings, the workpiece on the temporary storage table 3 can be grabbed by the reversing claw 2 and rotated to an angle convenient for the workpiece taking manipulator to take the workpiece, such as 90°. The workpiece on the reversing claw 2 can also be placed on the temporary storage table 3 by controlling the movement of the swing arm 21 to the temporary storage table 3, so that the workpiece after the angle is adjusted is grabbed by the workpiece taking manipulator and sent to the next process.

[0037] The swing arm 21 is fixed with a baffle 22, which is located between the reversing claw 2 and the gear 13, and ensures that the projection area of the gear 13 and the rack 12 is completely in the projection area of the baffle 22 to the reversing claw 2, so that the baffle 22 completely shields the gear 13 and the rack 12 of the gear 13 and the rack 12 of the rotating device 1, and then avoids the cuttings and metal scraps on the workpiece clamped by the reversing claw 2 from falling directly on the gear 13 and the rack 12 when the reversing claw 2 is located directly above the gear 13 and the rack 12, thereby avoiding pollution and ensuring that the maintenance of the rotating device 1 is not affected.

[0038] When the hub bearing part needs to be machined, the workpiece is placed on the temporary table 3, and if the workpiece does not need to be reversed and taken away by the taking manipulator, the rotating device 1 does not need to be started.

[0039] If the workpiece needs to be rotated and taken away, the rotating device 1 drives the rack 12 to move through the linear drive 11, so that the gear 13 rotates and drives the swing arm 21 to swing. The reversing claw 2 is close to the temporary table 3 under the action of the swing arm 21, and the reversing claw 2 clamps the workpiece (such as the shaft section of the workpiece at this time) on the temporary table 3. Then the rotating device 1 drives the swing arm 21 to restore to the vertical state, so as to clamp the workpiece to rotate 90°, and then the flange section of the workpiece is clamped by the taking manipulator.

[0040] The blowing pipe 5 blows the workpiece to blow off the cuttings or metal scraps on the surface of the workpiece.
