[0020] The supporting flip table 1 is a horizontally arranged circular table-shaped structure, which drives the front and rear pushing and flipping mechanisms 2 to slide relative to each other along the front-to-back direction through the lateral sliding component, and drives the left and right adjusting clamping mechanisms 3 to slide relative to each other along the left-right direction through the longitudinal sliding component.

[0021] The transverse sliding assembly includes a transverse slide rail, a transverse sliding seat 7, a first bidirectional adjustment screw rod 5, a first guide rod 6, and a first motor.

[0038] The present invention provides a method for using a large-scale annular workpiece turning device with a turning mechanism, comprising the following steps: Step 1: First, all motors and electronic components on the flipping device are powered on, and then the linear motor in the linear motor slider 15 is started. Under the cooperation of the linear motor and the longitudinal slide rail 16, the two lifting support blocks are driven away from each other. Then the first motor is started, and the first motor drives the first bidirectional adjustment screw 5 to rotate, and the first bidirectional adjustment screw 5 drives the two lateral sliding seats 7 to move closer to each other, thereby driving the lifting push rods 8 and the support push assembly 9 on the front and rear sides to move closer to each other. The large annular workpiece is then placed on the abutment plates 13 of the four groups of support and pushing assemblies 9, and the lower end surface of the large annular workpiece is supported by four horizontal abutment plates 13. At the same time, the lower end surface of the large annular workpiece presses down a portion of the telescopic support rod 10, and the upper end of this portion of the telescopic support rod 10 drops to the inside of the telescopic hole on the abutment plate 13. In addition, there is a portion of the telescopic support rod 10 that is not pressed down by the large annular workpiece. This portion of the telescopic support rod 10 that is not pressed down is located outside the outer cylindrical surface of the large annular workpiece. This portion of the telescopic support rod 10 that is not pressed down can prevent the large annular workpiece from accidentally slipping.

[0039] Step 2, then start the second motor, the second motor drives the lifting screw to rotate, the lifting screw drives the lifting seat to descend, and the lifting seat drives the first clamping plate 19 and the second clamping plate 20 to descend, so that the height of the area between the first clamping plate 19 and the second clamping plate 20 corresponds to the height of the large annular workpiece. And start the fourth motor, the fourth motor drives the second bidirectional adjustment screw 25 to rotate, thereby driving the first clamping plate 19 and the second clamping plate 20 away from each other. Then start the linear motor of the linear motor module, and under the mutual cooperation of the linear motor and the longitudinal slide rail 16, drive the two lifting support blocks to approach each other, so that the first clamping plate 19 and the second clamping plate 20 move to the upper and lower sides of the outer edge of the large annular workpiece. Then start the fourth motor again, drive the first clamping plate 19 and the second clamping plate 20 to approach each other, and the first clamping plate 19 and the second clamping plate 20 on both sides respectively clamp and fix the outer edge of the large annular workpiece. By moving the two sliding clamps 27 on the second clamp 20 away from each other, the two sliding clamps 27 can be unfolded, thereby increasing the overall arc of the second clamp 20, making the force range of the large annular workpiece clamping more dispersed and improving the stability of the clamping.

[0040] Step three, start the second motor, driven by the lifting screw, the lifting seat drives the clamping assembly 17 to start rising, and the clamping assemblies 17 on both sides drive the large annular workpiece to rise to the flipping height. Then start the third motor, the third motor drives the transmission worm 30 to rotate through the mutually meshing driving gear and the driven gear, the transmission worm 30 drives the fixed worm wheel 29 to rotate, the fixed worm wheel 29 drives the clamping adjustment box 21 to rotate, the clamping adjustment box 21 drives the first clamping plate 19 and the second clamping plate 20 to rotate at the same time, and then drives the large annular workpiece to flip. The transmission worm 30 and the fixed worm wheel 29 form a self-locking anti-deflection structure, so that the deflection of the large annular workpiece is more stable, and can prevent the large annular workpiece from driving the clamping assembly 17 to deflect the self-locking anti-deflection assembly due to its heavy weight.

[0041] Step 4: When the third motor starts to start, that is, when the large annular workpiece starts to flip, the first motor is started, and the first motor drives the first bidirectional adjustment screw 5 to rotate, and the first bidirectional adjustment screw 5 drives the two lateral sliding seats 7 to approach each other, thereby driving the lifting push rods 8 and the support push assembly 9 on the front and rear sides to approach each other. At the same time, the two lifting push rods 8 on the lateral sliding seat 7 on one side are controlled to shrink synchronously, and the two lifting push rods 8 on the lateral sliding seat 7 on the other side are extended synchronously, so that the two abutment plates 13 on one side move downward synchronously with the end of the large annular workpiece rotating downward, and the two abutment plates 13 on the other side move upward synchronously with the end of the large annular workpiece rotating upward. The abutment plates 13 moving upward and the abutment plates 13 moving downward are both rotated with the hinge seat 12 to ensure that the upper end surface of the abutment plate 13 is always in contact with the bottom surface of the large annular workpiece. The abutment plate 13 moving upward pushes up the end of the large annular workpiece rotating upward to help the large annular workpiece flip. The telescopic support rod 10 that is not pressed down on the downwardly moving abutment plate 13 supports the lower end of the outer cylindrical surface of the large annular workpiece, thereby facilitating the flipping of the large annular workpiece and preventing the large annular workpiece from being disengaged from the clamping and fixing of the clamping assembly 17 due to its heavy weight. When the large annular workpiece flips to a nearly vertical state, the lateral sliding seats 7 on both sides are about to come into contact with the supporting block. At this time, all the lifting push rods 8 are controlled to shrink to the shortest state, so that all the abutment plates 13 are disengaged from the large annular workpiece. Then the first motor is started, and the first motor drives the first two-way adjustment screw 5 to rotate, and the first two-way adjustment screw 5 drives the two lateral sliding seats 7 to move away from each other, thereby driving the lifting push rods 8 on the front and rear sides and the support push assembly 9 to move away from each other.

[0042] Step 5: After the support and pushing components 9 on both sides are separated from the large annular workpiece, the large annular workpiece is driven to continue to rotate to a vertical state through the clamping components 17 on both sides. Then the second motors on both sides are started, and the second motors drive the lifting screws to rotate, the lifting screws drive the lifting seat to descend, the lifting seat drives the clamping components 17 to descend, and the clamping components 17 drive the vertical large annular workpiece to descend to the inside of the supporting groove of the supporting block, and the lower end of the outer cylindrical surface of the large annular workpiece contacts the detection supporting roller 31 and the toggle supporting roller 32, and the abutment springs 34 at both ends of the detection supporting roller 31 and the toggle supporting roller 32 are compressed, so that the outer cylindrical surface of the large annular workpiece maintains good contact with the two detection supporting rollers 31 and one toggle supporting roller 32. Then start the fifth motor 37, which drives the supporting roller 32 to rotate inside the supporting block. The supporting roller 32 drives the large annular workpiece to rotate through the outer friction transmission sleeve 36. The rotating large annular workpiece drives the detection supporting rollers 31 on both sides to rotate. When the large annular workpiece rotates, the outer cylindrical surface of the large annular workpiece always maintains rolling contact with the abutting rollers 28 on the first clamping plate 19 and the second clamping plate 20, and the stability of the large annular workpiece during rotation is ensured by the abutting rollers 28 on both sides. When the detection support roller 31 rotates, the detection ball 35 on the outside of the detection support roller 31 will be squeezed by the large annular workpiece to compress the second spring 38, and the second spring 38 will squeeze the pressure sensor 39. The piezoresistive pressure sensor 39 uses the piezoresistive effect. When the material is subjected to mechanical stress, its resistance value will change. The pressure is determined by measuring the change in resistance value. Through the setting of each fluctuation detection component, each detection ball 35 is coordinated with the rotation of the large annular workpiece, so as to detect the flatness of the outer ring of the large annular workpiece.

[0043] Step 6: After the outer ring flatness detection of the large annular workpiece is completed, the second motors on both sides are started, so that the lifting seats on both sides begin to rise, and the lifting seats on both sides drive the large annular workpiece to rise through the clamping assembly 17. When the large annular workpiece rises to the flipping height, the clamping assemblies 17 on both sides drive the large annular workpiece to continue flipping. When the large annular workpiece flips to a certain angle, the lateral sliding seats 7 on both sides approach each other, and the lifting push rod 8 is controlled to extend, so that the support and push assembly 9 on one side continues to push up one side of the large annular workpiece, and the support and push assembly 9 on the other side supports the other side of the large annular workpiece, which not only assists the large annular workpiece to flip smoothly, but also prevents the large annular workpiece from being separated from the clamping assembly 17 due to its heavy weight. Until the large annular workpiece flips to a horizontal state, the clamping assemblies 17 on both sides are separated from the large annular workpiece, and the longitudinal sliding seats 14 on both sides are away from each other, and the large annular workpiece is placed on the support and push assembly 9, and the use of the flipping device is completed.
