[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a sheet metal turning device and a stainless steel sheet metal turning method.

[0032] Example 1: Please refer to Figures 1-4 A sheet metal turning device comprises a bed 1, a spindle 2, a guide rail 3, a feed seat 4 and a tool holder 5 installed in the bed 1, a vibration plate 6, a drive assembly 7, a fixture 8 and a flip assembly 9 are also installed in the bed 1, the fixture 8 is movably installed on the vibration plate 6, the fixture 8 is used to clamp and fix the workpiece, the flip assembly 9 is installed on the vibration plate 6 and is connected to the fixture 8 by transmission, the flip assembly 9 is used to drive the fixture 8 to swing, the drive assembly 7 comprises a movable seat 71 installed on the guide rail 3, the drive assembly 7 is used to drive the vibration plate 6 to move toward the spindle 2, the vibration plate 6 is fixedly installed on the movable seat 71, and the vibration plate 6 is used to vibrate the workpiece to remove stress;

[0033] During the cutting operation, first, rough machining is performed on the workpiece using a rough machining tool. After rough machining, the driving component 7 and the flipping component 9 operate. The driving component 7 forces the vibrating bowl 6 to move towards the main shaft 2, and the flipping component 9 forces the fixture 8 to flip and face the workpiece on the main shaft 2. When the fixture 8 moves to the workpiece, the fixture 8 operates to clamp and fix the workpiece. Subsequently, the driving component 7 and the flipping component 9 operate again to control the fixture 8 to reset. The vibrating bowl 6 operates to vibrate the workpiece for a certain period of time to eliminate stress. Finally, the driving component 7 and the flipping component 9 operate again to force the workpiece to move and be installed on the main shaft 2, and then finish machining is performed on the workpiece using a finish machining tool.

[0034] Among them, the workpiece is a stainless steel sheet metal part. The tool rest 5 has multiple installation positions. During actual use, the rough machining tool and the finish machining tool are selected according to requirements and installed on the tool rest 5. A sensor for testing the vibration effect is fixedly installed at the corner of the vibrating bowl 6. The sensor is externally connected to a vibration aging device, and the vibrating bowl 6 is horizontally arranged;

[0035] During use, first fix the workpiece raw material on the main shaft 2, start the main shaft 2 and the feed seat 4, so that the rough machining tool contacts the rotating workpiece to perform rough machining on the workpiece. When the rough machining is completed, start the flipping component 9 and the driving component 7. When the flipping component 9 operates, it drives the fixture 8 to flip, so that the fixture 8 faces the workpiece on the main shaft 2. When the driving component 7 operates, it drives the vibrating bowl 6 to move towards the main shaft 2, thereby driving the fixture 8 to move towards the main shaft 2 until the workpiece is located inside the fixture 8. Subsequently, start the fixture 8, and the fixture 8 clamps the workpiece. At the same time, the main shaft 2 releases the fixation of the workpiece. At this time, the workpiece is fixed on the fixture 8. Then restart the driving component 7 and the flipping component 9 to make the fixture 8 reset. At this time, the workpiece is fixed on the vibrating bowl 6 by the fixture 8. At this time, start the vibrating bowl 6 to vibrate the workpiece, thereby eliminating its stress. When vibrating for a certain period of time, turn off the vibrating bowl 6, and start the flipping component 9 and the driving component 7 again to move the workpiece on the fixture 8 back to the main shaft 2. After the main shaft 2 clamps the workpiece, start the fixture 8 to loosen the workpiece, so that the workpiece is fixed on the main shaft 2 again, and then finish machining is performed using the finish machining tool;

[0036] By arranging the driving component 7, the vibrating bowl 6, the fixture 8 and the flipping component 9 on the bed body 1, when machining a stainless steel sheet metal workpiece, first perform rough machining, and then use the driving component 7, the fixture 8 and the flipping component 9 to transfer and fix the workpiece on the main shaft 2 to the vibrating bowl 6, and then use vibration to eliminate the stress of the workpiece. Finally, transfer and fix the workpiece back on the main shaft 2 for finish machining. Through this method of rough machining, stress relief and finish machining, it can adapt to the turning machining of stainless steel sheet metal parts, reduce the probability of workpiece deformation, and is beneficial to improving the machining quality of products.

[0037] Embodiment 2: Refer to Figures 5-7, different from the above embodiments, the fixture 8 includes a substrate 801. A base shaft 802 is fixed to one side edge of the substrate 801. The base shaft 802 is movably installed on the vibrating disk 6 through a first bearing block 803. A circular groove 804 is formed on the back surface of the substrate 801. An assembly groove 805 and a plurality of chutes 806 distributed in an annular array around the assembly groove 805 are formed on the front surface of the substrate 801. A plurality of clamping jaws 80 corresponding to the positions of the chutes 806 are further installed on the front surface of the substrate 801. A first motor 807 is fixed in the assembly groove 805. The first motor 807 is used to drive multiple groups of clamping jaws 80 to move. The clamping jaw 80 includes a frame body 808 fixed to the front surface of the substrate 801. The frame body 808 is provided with main support rods 809 and auxiliary support rods 810 that are of the same length and are distributed in parallel. The bottom ends of the main support rod 809 and the auxiliary support rod 810 are both rotatably connected to the frame body 808. The clamping jaw 80 further includes a clamping block 811. The clamping block 811 and the frame body 808 are both parallel to the front surface of the substrate 801. The clamping block 811 is hinged to the top ends of the main support rod 809 and the auxiliary support rod 810. A spring 812 is further connected between the middle of the auxiliary support rod 810 and the end of the frame body 808. A driven gear 813 is fixed to the bottom end of the main support rod 809. The output end of the first motor 807 extends into the circular groove 804 and is fixedly connected to a disk 814. A plurality of arc-shaped holes 815 distributed in an annular array are formed on the surface of the disk 814. A rack 816 is slidably connected in each of the plurality of chutes 806. The rack 816 meshes with the driven gear 813. A pin 817 is fixed to the side of the rack 816 close to the disk 814. The pin 817 is inserted into the arc-shaped hole 815.

[0038] Among them, the chute 806 communicates with the circular groove 804. In the initial state, the substrate 801 is horizontal and fits against the vibrating disk 6. A plurality of uniformly distributed screw holes are provided on the front surface of the substrate 801. The distribution direction of the screw holes is the same as the direction of the chute 806. The frame body 808 is fixed by screwing bolts into the screw holes. In this way, the position of the frame body 808 can be adjusted by matching the bolts with different screw holes, and then the position of the clamping jaw 80 can be adjusted to adapt to workpieces of different diameters.

[0039] During use, after the fixture 8 moves towards the workpiece, the workpiece is located inside the fixture 8. At this time, the first motor 807 is started. When the first motor 807 operates, it drives the disc 814 to rotate. When the disc 814 rotates, it pushes the pin 817 through the arc-shaped hole 815, causing the pin 817 and the rack 816 to slide along the chute 806. When the rack 816 moves, it drives the driven gear 813 to rotate. When the driven gear 813 rotates, it drives the main support rod 809 to swing. When the main support rod 809 swings, it drives the clamping block 811 to move, and also causes the auxiliary support rod 810 to swing synchronously. The swinging amplitude of the auxiliary support rod 810 is the same as that of the main support rod 809. And when the auxiliary support rod 810 swings, it also stretches the spring 812. The clamping block 811 remains parallel to the surface of the base plate 801 and gradually approaches the base plate 801. When multiple clamping blocks 811 move simultaneously, the workpiece can be clamped and fixed.

[0040] By setting the fixture 8, when the first motor 807 is started, it can drive multiple clamping blocks 811 to move synchronously, thereby clamping and fixing the workpiece, which is beneficial for transporting the workpiece and keeping the workpiece stable during vibration stress relief to improve the stress relief effect. Since the clamping block 811 can keep parallel to the surface of the clamping plate 801 during the moving process, it can adapt to workpieces of different thicknesses, with high applicability.

[0041] Embodiment 3. Refer to Figure 5 , different from the above embodiment, a push rod 818 is fixed at the end of the base shaft 802. The angle between the push rod 818 and the plane where the base plate 801 is located is set as an acute angle. The flipping assembly 9 includes two support blocks 91 fixed on the vibrating disc 6. Between the two support blocks 91, a transmission screw rod 92 and a guide rod 93 are arranged in parallel. The two ends of the transmission screw rod 92 are respectively rotatably connected to the two support blocks 91. The two ends of the guide rod 93 are respectively fixed to the two support blocks 91. A nut sleeve 94 is threadedly connected to the transmission screw rod 92. The nut sleeve 94 is also movably sleeved on the guide rod 93. One end of the push rod 818 away from the base shaft 802 is rotatably connected to a connecting rod 95. One end of the connecting rod 95 away from the push rod 818 is rotatably connected to the nut sleeve 94. The flipping assembly 9 further includes a second motor 96 fixed on the vibrating disc 6.

[0042] Among them, the transmission screw rod 92 and the guide rod 93 are both perpendicularly distributed to the base shaft 802. During use, when the second motor 96 is started, the second motor 96 drives the transmission screw rod 92 to rotate. When the transmission screw rod 92 rotates, it drives the nut sleeve 94 to move. When the nut sleeve 94 moves, it drives one end of the connecting rod 95 to move. When one end of the connecting rod 95 moves, the other end pulls the push rod 818, thereby causing the push rod 818 to swing. When the push rod 818 swings, it drives the base shaft 802 to rotate. When the base shaft 802 rotates, it drives the base plate 801 to flip. Similarly, when the second motor 96 drives the transmission screw rod 92 to rotate in the reverse direction, it drives the base plate 801 to flip in the reverse direction to reset the base plate 801.

[0043] By setting the flipping component 9, when the second motor 96 is started, the substrate 801 can be driven to flip, changing the angle of the fixture 8, facilitating the fixture 8 to clamp and fix the workpiece on the main shaft 2, and then transferring and fixing the workpiece on the main shaft 2 to the vibrating disk 6.

[0044] Example 4, refer to Figure 5 、 Figure 8 and Figure 9 , different from the above embodiments, the vibrating disk 6 includes a bottom plate 61 and a top plate 62 mounted on the top surface of the bottom plate 61. The fixture 8 and the flipping component 9 are both mounted on the top plate 62. A plurality of rubber blocks 63 are fixedly connected between the bottom surface of the bottom plate 61 and the movable seat 71. An exciter 64 is fixed at the center of one side edge of the top plate 62.

[0045] Among them, the top plate 62 is set to be rectangular. When the exciter 64 operates, it drives the bottom plate 61 and the top plate 62 to vibrate. The amplitude of the top plate 62 gradually increases near both ends. The fixture 8 is fixed at the position with a larger amplitude. When the top plate 62 vibrates, it can drive the workpiece on the fixture 8 to vibrate. After a period of time, the stress of the workpiece can be eliminated, and the probability of workpiece deformation can be reduced.

[0046] Example 5, refer to Figures 1-4 , different from the above embodiments, the driving component 7 includes a driving motor 72 fixed on the machine body 1. The output shaft of the driving motor 72 is fixed with a driving screw 73. The driving screw 73 is installed on the side of the guide rail 3 through a second bearing block 74. A nut seat 75 is also threadedly connected to the driving screw 73. The movable seat 71 is fixedly connected to the nut seat 75, and the movable seat 71 is also slidably connected to the guide rail 3.

[0047] Among them, the driving screw 73 and the guide rail 3 are distributed in parallel. When in use, the driving motor 72 is started. When the driving motor 72 operates, it drives the driving screw 73 to rotate. The driving screw 73 drives the nut seat 75 and the movable seat 71 to slide along the guide rail 3, thereby driving the vibrating disk 6 to move towards the main shaft 2.

[0048] Example 6, refer to Figure 5 and Figure 8, different from the above embodiment, two sets of the clamps 8 are provided, the driving screw rod 92 is a bidirectional screw rod and two symmetrically distributed nut sleeves 94 are mounted on the surface thereof, and the two nut sleeves 94 are respectively connected to the push rods 818 on the two clamps 8 through connecting rods 95. A vertical shaft 65 is fixedly provided at the center of the top plate 62. The bottom end of the vertical shaft 65 penetrates through the bottom plate 61 and is rotatably connected to the bottom plate 61. A worm gear 66 is fixedly provided at the bottom end of the vertical shaft 65. A fourth motor 67 is fixedly provided at the bottom of the bottom plate 61. A worm 68 is fixedly provided on the output shaft of the fourth motor 67. The worm 68 is mounted on the bottom of the bottom plate 61 through a third bearing seat 69. The worm 68 meshes with the worm gear 66.

[0049] Wherein, two sets of symmetrically distributed threads with opposite helix directions are provided on the driving screw rod 92, and the two nut sleeves 94 respectively match the two sets of threads. During use, when a workpiece is clamped on one of the clamps 8 on the vibrating disk 6, the other clamp 8 is selected for the next workpiece clamping. At this time, the fourth motor 67 is started. After the fourth motor 67 operates, it drives the worm 68 to rotate. After the worm 68 rotates, it drives the worm gear 66 to rotate. After the worm gear 66 rotates, it drives the vertical shaft 65 and the top plate 62 to rotate. When the top plate 62 rotates 180 degrees, the positions of the two clamps 8 can be interchanged. Moreover, when the turning assembly 9 operates and the driving screw rod 92 rotates, it will also drive the two nut sleeves 94 to move at the same time, so as to drive the two clamps 8 to turn at the same time, achieving the effect of double-station operation.

[0050] By providing two sets of the clamps 8, the fourth motor 67 can be used to drive the positions of the two clamps 8 to be interchanged, and the turning assembly 9 can also control the two clamps 8 to turn at the same time, which is beneficial to realizing double-station operation. During actual use, the stress relief process of the workpiece can be synchronized with the rough machining and fine machining of the workpiece, improving the processing efficiency.
