[0017] 1、The ball screw straightening machine can start the double-shaft motor according to the requirement before straightening the ball screw, so that the first double-tooth shaft is driven to roll on the rack through the driving gear, the slide is slid on the slide rail, the position of the supporting table during supporting is changed, the local range of the ball screw is straightened according to the requirement, the straightening range is wider, the micrometer is integrated on the electric cylinder, the position of the micrometer can be controlled through the adjusting assembly, the multiple positions of the screw rod can be detected, the detection effect is improved, the brush can be attached to the ball screw during the detection process, the surface of the ball screw can be cleaned in advance, the detection accuracy of the micrometer is not affected by the impurities attached to the surface, the interference is reduced, the brush is in the cross shape, the surface of the screw rod can be cleaned when the brush is horizontally moved or the screw rod is rotated, and the cleaning effect is improved.

[0018] 2、During the detection process, when the electric cylinder drives the supporting table to move downwards, the connecting rod pulls the limiting frame to slide along the guide frame, the detection plate can be moved to the bottom of the ball screw through the guide rod, the end of the detection plate is inclined, has a certain guiding effect, the screw rod in a certain size can be detected, the use range of the equipment is improved, then the compression spring pushes the detection plate to be attached to the screw rod, so that the detection plate moves synchronously when the screw rod is bent, the micrometer can observe the bending condition of the screw rod by measuring the position of the detection plate, when the electric cylinder drives the supporting table to move upwards to support the ball screw, the connecting rod pushes the limiting frame, so that the detection plate moves away from the bottom of the ball screw and automatically avoids, so that the subsequent pressing and straightening operation is performed.

[0019] 3、The electric cylinder drives the supporting table to move upwards before straightening, so that the float needles are in contact with the bottom of the ball screw, the arc formed by the top of the multiple float needles can be attached to the arc of the bottom of the screw rod under the action of the return spring, and the attachment degree is further improved through the deformation performance of the rubber pad, the locking plate extrudes the float needles by rotating the locking screw, the friction between the multiple float needles is increased due to the rough surface of the float needles, the position of the float needles after movement is locked, the float needles do not slide under subsequent extrusion, the stability during straightening is improved, so that the top of the float needles is attached to the bottom of the ball screw during subsequent straightening, the pressure is uniformly distributed, the local pressure loss of the ball screw is reduced, and secondary damage of the ball screw during straightening is avoided.

[0020] 4. In this invention, when the electric cylinder moves to clean the bottom of the ball screw with the brush, the dual-shaft motor also drives the second double-toothed shaft to rotate. At this time, due to the electromagnet attracting the permanent magnet, the adjusting sleeve drives the synchronous sleeve to move downward, and the gear ring will mesh with the reversing gear. The second double-toothed shaft will drive the fan blade shaft to rotate through the reversing gear, gear ring, and synchronous sleeve, which can create a negative pressure at the top of the fixed box. This allows the dust swept off by the brush to be adsorbed and collected through the through hole at the top of the fixed tube, which is more environmentally friendly. At the same time, impurities in the airflow are filtered by the filter plate and discharged from the bottom. At this time, under the action of the guide plate, the airflow is blown towards the first double-toothed shaft. The shaft and rack can be air-cleaned to prevent impurities from adhering to their surfaces and accelerating wear, thus extending the service life of the equipment. When the current direction is changed to reverse the dual-shaft motor, the current direction of the electromagnet is also changed. At this time, the magnetic poles of the electromagnet are reversed, and the permanent magnet is pushed by the repulsive force, causing the adjusting sleeve to move upward, thereby separating the gear ring from the reversing gear. At this time, the synchronization sleeve will directly engage with the second double gear shaft, so that the rotation direction of the fan blade shaft will not be changed when the dual-shaft motor rotates forward or in reverse, so that it can only perform suction operation on the top of the fixed box, thus maintaining the normal operation of the dust collection component.
