DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Please refer to Figures 1-3, the present utility model provides a workpiece turnover mechanism for hardness testing, including a workbench 10. Three V-shaped toolings 2 are installed on the upper surface of the workbench 10. A workpiece 1 is placed in the V-shaped groove of the V-shaped tooling 2. A roller mounting seat 7 is arranged between two adjacent V-shaped toolings 2. Six rollers 14 are arranged in the roller mounting seat 7. The six rollers 14 are grouped in pairs of two, and a group of two rollers 14 cooperate with the workpiece 1. The end of the roller 14 in the roller mounting seat 7 at the front side is fixedly installed with a driven double sprocket 11. A sprocket servo motor 3, a reducer 4, a steering servo motor 16 and a steering gear 9 are arranged on the workbench 10. The output shaft of the sprocket servo motor 3 is connected to the input shaft of the reducer 4. The output shaft of the reducer 4 is installed with a driving sprocket 12. The driving sprocket 12 and the driven double sprocket 11 are connected by chain drive. Lifting devices 6 are installed at both ends of the roller mounting seat 7. The output shaft of the steering servo motor 16 is used in cooperation with the steering gear 9, and the steering gear 9 is used in cooperation with the lifting device 6.

[0024] By arranging three V-shaped toolings 2, the cylindrical workpiece 1 can be stably placed, and the workpiece 1 is not easily deformed when hardness testing pressure is applied. Two roller mounting seats 7 are installed between the three V-shaped toolings 2. Both the left and right sides of the roller mounting seat 7 are driven by the lifting devices 6 to rise and achieve turnover, so that the workpiece 1 is separated from the V-shaped tooling 2 and turned over. The structure is simple and can be disassembled without using the rollers 14 and the roller mounting seat 7 to perform hardness testing on workpieces 1 of other shapes, with strong compatibility. The rollers 14 adopt sprocket drive, with large transmitted torsion, high transmission efficiency and stable transmission.

[0025] A reducer fixing seat 13 is fixedly installed on the workbench 10. The sprocket servo motor 3 and the reducer 4 are both installed on the side of the reducer fixing seat 13. The reducer fixing seat 13 is used to install the sprocket servo motor 3 and the reducer 4, with good installation stability and not easily loosening or shaking.

[0026] A lifting device fixing seat 5 is fixedly installed on the workbench 10. The lifting device 6 is installed on the lifting device fixing seat 5. The lifting device fixing seat 5 is used to install the lifting device 6, which can ensure the stable lifting of the roller mounting seat 7 by the lifting device 6 and ensure good motion stability.

[0027] A steering servo motor fixing seat 17 and a steering gear fixing seat 8 are fixedly installed on the workbench 10. The steering servo motor 16 is installed on the steering servo motor fixing seat 17, and the steering gear 9 is installed on the steering gear fixing seat 8. The steering servo motor 16 is installed by using the steering servo motor fixing seat 17, and the steering gear 9 is installed by using the steering gear fixing seat 8, with good installation stability.

[0028] A set of two rollers 14 are symmetrically distributed on both sides of the central axis of the V-shaped groove of the V-shaped tooling 2, which can ensure that when the roller mounting seat 7 moves upward to lift, the workpiece 1 can just be clamped between the set of two rollers 14, thereby realizing the effective flipping of the workpiece 1.

[0029] Both ends of the roller 14 are rotatably installed with bearing seats 15, and the bearing seats 15 are fixedly installed on the upper surface of the roller mounting seat 7. Using the bearing seats 15 to connect the rollers 14 can ensure the smooth rotation of the rollers 14.

[0030] During use, the cylindrical workpiece 1 is placed between three V-shaped toolings 2. When performing hardness testing, the workpiece 1 is in a separated state from the rollers 14. After the hardness of one side of the workpiece 1 is tested, the steering servo motor 16 drives the steering gear 9 to rotate, the steering gear 9 drives the lifter 6 to rise, the lifter 6 drives the roller mounting seat 7 to rise, and the roller mounting seat 7 drives the rollers 14 to rise. At this time, the rollers 14 contact the workpiece 1 and lift the workpiece 1 to be separated from the V-shaped tooling 2. Then the steering servo motor 16 stops working, and the sprocket servo motor 3 starts and drives the driving sprocket 12 to rotate through the speed reducer 4. The driving sprocket 12 drives the driven double sprocket 11 to rotate through the chain, thereby driving the rollers 14 to rotate, and using the rotation of the rollers 14 to drive the workpiece 1 to rotate to realize the flipping of the workpiece 1. After the workpiece 1 rotates and flips to a certain angle, the sprocket servo motor 3 is stopped, and then the steering servo motor 16 drives the steering gear 9 to rotate in the reverse direction. The steering gear 9 drives the lifter 6 to descend, thereby driving the roller mounting seat 7 to move downward, so that the rollers 14 descend until the workpiece 1 falls into the V-shaped tooling 2, and then the hardness test is performed on the surface of the new workpiece 1.
