Based on the above embodiments, the technical problem to be solved by the present application is how to enable a straightening machine to automatically determine whether a shaft is bent and perform automatic straightening after the determination. For this reason, this application transfer chain 2 sets up on base 1's upper portion, and the length direction of transfer chain 2 is parallel to each other with base 1's length direction, and support 3 is fixed to be set up on base 1's upper portion, and bracing piece 5 is provided with a plurality ofly, and bracing piece 5 is along even arranging of length direction of transfer chain 2. The support rod 5 is used for receiving the shaft parts. The theory of operation of straightening mechanism 4 is as follows, when transfer chain 2 drove the axle type piece on the bracing piece 5 and removed to straightening mechanism 4's below, transfer chain 2 just can the bring to rest this moment, lifting unit 4b just can begin to start afterwards, lifting unit 4b can drive and set up the pressing piece 4c and the removal of rotary drive subassembly 4a towards transfer chain 2 slowly of its lower part, pressing piece 4c can meet with the bracing piece 5 that sets up on transfer chain 2 this moment, the one end that pressing piece 4c is close to bracing piece 5 is half circular structure, bracing piece 5 is close to the one end of pressing piece 4c and is half circular structure, so after pressing piece 4c meets with bracing piece 5, pressing piece 4c and bracing piece 5 just can restrict axle type piece this moment. When the pressing member 4c is connected to the supporting rod 5, the rotation driving member 4a disposed below the lifting member 4b is connected to the shaft member, and after the rotation driving member 4a is started, the rotation driving member 4a drives the shaft member to rotate. The shaft part is only machined on one side of the shaft part during machining. This causes a bending phenomenon to occur on one side of the shaft. When one side of the shaft part is bent, the circle run-out degree of the shaft part inevitably generates deviation, so that the judgment on whether the shaft part is bent or not can be realized by measuring the circle run-out degree of the shaft part. When the rotary driving assembly 4a drives axle type piece rotatory, the axle type piece was kept away from one side of rotary driving assembly 4a this moment and can be contacted with circle monitoring components 4g of beating, and circle monitoring components 4g of beating sets up in the below of axle type piece, and after axle type piece was driven rotatory by rotary driving assembly 4a, circle monitoring components 4g of beating alright read out the circle degree of beating of axle type piece. If the circle run-out degree is within the range of the preset value, the shaft part is not bent, when the circle run-out monitoring component 4g monitors that the circle run-out degree of the shaft part is larger than the preset value, the circle run-out monitoring component 4g feeds back a signal to the first linear driver 4d, the first linear driver 4d is preferably a servo electric cylinder, the first linear driver 4d is started after receiving the signal, the first linear driver 4d drives the straight-pushing part 4f arranged on the output end of the first linear driver to slowly extend out, finally, the straight-pushing part 4f is connected with the side wall of the shaft part, the straight-pushing part 4f applies a pressure to the shaft part, and the pressure can correct the shaft part. When the shaft part is corrected, the circle run-out monitoring assembly 4g arranged at the lower part of the shaft part still monitors the circle run-out degree of the shaft part, and when the circle run-out degree of the shaft part is monitored within a preset value range, the first linear driver 4d drives the straight-pushing part 4f to shrink, so that the technical requirement that the straight-pushing machine can automatically judge whether the shaft part is bent and automatically correct after judgment is met.

the circular runout monitoring assembly 4g comprises a contact element 4g1, a partition plate 4g2, a spring 4g3, a limiting plate 4g4 and a distance measuring sensor 4g5; the partition plate 4g2 is fixedly arranged on the side wall of the conveying line 2; the contact element 4g1 is arranged at the upper part of the partition plate 4g2, the contact element 4g1 is arranged above the partition plate 4g2, a first gap is reserved between the contact element 4g1 and the partition plate 4g2, the bottom of the contact element 4g1 is provided with a guide rod, and the guide rod is arranged on the partition plate 4g2 in a sliding manner; the spring 4g3 is arranged in the first gap; the limiting plate 4g4 is fixedly arranged at one end of the guide rod away from the contact element 4g 1; the distance measuring sensor 4g5 is arranged below the limiting plate 4g4, and the output end of the distance measuring sensor 4g5 points to the limiting plate 4g4.

Based on the above embodiments, the technical problem that the present application intends to solve is how to monitor the circular runout degree of the shaft component by the circular runout monitoring assembly 4 g. For this reason, this application contact 4g1 is "Y" shape structure, and when monitoring, axle type spare can contact with contact 4g1, if axle type spare has crooked situation, axle type spare then just can push contact 4g1 top, and contact 4g1 can drive the guide bar that sets up in its lower part this moment and slide on baffle 4g2, and limiting plate 4g4 that set up on the guide bar this moment just can be driven. The distance measuring sensor 4g5 is preferably of a laser type, so that when the limiting plate 4g4 is displaced, the distance measuring sensor 4g5 can measure the moving distance of the limiting plate 4g4, and therefore the monitoring of the circular runout of the shaft part can be achieved. Thus, the monitoring function of the circular runout monitoring assembly 4g is realized.
