[0018] Thread between screw 5 and connecting plate 4 can realize self-locking, and the self-locking condition depends on the spiral angle of thread, friction coefficient and the load. The self-locking condition can be calculated by the following formula: self-locking condition=friction coefficient*tan(spiral angle) >=1. When this condition is met, the threaded connection is self-locking. The above content is prior art, and the corresponding self-locking angle can be set according to the friction coefficient of the material in actual application, which is not described here; when the lead angle (λ) of worm 15 is less than the friction angle (φ) of the contact surface of worm gear 16 and worm 15, the transmission system of worm gear 16 and worm 15 can realize self-locking, and through external power equipment, worm 15 can be driven to rotate clockwise and counterclockwise, and then the clockwise rotation and counterclockwise rotation of worm gear 16 are realized.

[0019] The implementation principle of the flattening device for machining according to an embodiment of the application is as follows: the electrical elements appearing in the application are externally connected to a power supply and a control switch during use. During use, a worker can drive the screw rod 5 to rotate through the rotating wheel 6, the screw rod 5 can drive the connecting plate 4 to move vertically, the connecting plate 4 can drive the sliding block 2 to move through the connecting rod 3, the sliding block 2 can drive the upper pressing roller 7 thereon to move, and the worker can adjust the distance between the adjacent upper pressing roller 7 and lower pressing roller 8 according to actual needs, so that the distance between the multiple sets of upper pressing roller 7 and lower pressing roller 8 gradually decreases from left to right.

Then, the part to be flattened is placed between the upper pressing roller 7 and the lower pressing roller 8 on the left side, so that the part can be flattened during the process of being conveyed to the right. During this process, the upper pressing roller 7 can be driven to move by the rotating wheel 6, so that the worker can adjust the distance between the upper pressing roller 7 and the lower pressing roller 8 according to actual needs. The spacing between the three sets of upper pressing roller 7 and lower pressing roller 8 gradually decreases from left to right, so that the part can be progressively flattened. At the beginning, the pressing rollers with a larger spacing on the left side preliminarily flatten the part, so that the larger deformation and stress of the part can be eliminated, thereby laying a foundation for subsequent accurate flattening. As the part moves to the right, the pressing rollers with gradually decreasing spacing in the middle and on the right side further apply pressure to the part, so that the smaller deformation and unevenness of the part can be gradually corrected. This progressive flattening method can effectively avoid excessive deformation, fracture or internal defects of the part caused by one-time excessive pressure, and ensure that the flattening process is stable and effective.
