Then make the lifting cylinder 102 of the detection mechanism 10 drive the support base 103 to move up, and synchronously drive the fixed rod 104 and the swing rod 105 on the support base 103 to move up. The second contact block 12 will first contact with the rear end of the back of the fixed arm of the elevator guide rail 2, and as the support seat 103 continues to move up, the upper part of the swing rod 105 will gradually turn leftward and downward around the pin shaft 106, and at the same time the swing rod will The bottom of 105 can rotate upwards to the right gradually around pin shaft 106, and when the bottom of swing lever 105 turns rightward and upward around pin shaft 106, the bottom of swing lever 105 can synchronously push the inductive head of displacement sensor 108 to move to the right until When the support base 103 drives the first contact piece on the fixed rod 104 to contact the front end of the fixed arm back of the elevator guide rail 2, the action of the lifting cylinder 102 is stopped. At this time, the displacement sensor 108 will record the actual displacement of the sensor head. And the actual displacement and the preset theoretical horizontal displacement (theoretical horizontal displacement is defined as: the swing rod 105 rotates around the pin shaft 106 from the initial state to when the second contact block 12 is on the same level as the first contact block 11, the displacement sensor The displacement of the induction head being pushed by the swing rod 105) is compared to detect the degree of twisting of the elevator guide rail, and calculate the direction and angle that the twisting head group 9 needs to rotate relative to the fixed head group 6 according to the degree of twisting; then start again The two rotary lifting cylinders 72 of the pressing mechanism 7 make the two pressing plates 73 on the two rotary lifting cylinders rotate upward and outward respectively away from the elevator guide rail 2 on the guide rail feeding platform 3, and then make the dragging material centering mechanism 4 Move up to lift up the elevator guide rail 2 on the guide rail feeding platform 3, and then make the left thrust cylinder 82 drive the left moving seat 8 and the twisting head group 9 to move to the right until it moves to the elevator guide rail on the guide rail feeding platform 3. When the left end is located in the first ⊥-shaped positioning hole 94 of the twisting head group 9, the action of the left thrust cylinder 82 is stopped, and the right thrust cylinder 52 drives the right moving seat 5 and the fixed head group 6 to move to the left until they reach the guide rail When the right end of the elevator guide rail on the feeding platform 3 is located in the second ⊥-shaped positioning hole 62 of the fixed head group 6, stop the action of the right thrust cylinder 52; The tight block 96 moves down to compress and fix the left end of the elevator guide rail 2 in the first ⊥-shaped positioning hole 94, and the second lifting oil cylinder 63 of the fixed head group 6 drives the second pressing block 64 to move down to move the elevator guide rail 2 The right end of the right end is pressed and fixed in the second ⊥-shaped positioning hole 62.

When in contact, the action of the lifting cylinder 102 is stopped. At this time, the displacement sensor 108 will record the actual displacement of the induction head, and compare the actual displacement with the preset theoretical horizontal displacement, thereby detecting the twisting degree of the elevator guide rail. When it is detected that the elevator guide rail is still twisted, repeat the above actions until the correction of the elevator guide rail is completed;

After the elevator guide rail 2 has been corrected, the supporting centering mechanism 4 is moved up again to support the elevator guide rail 2 clamped by the twisting head group 9 and the fixed head group 6, and then the first part of the twisting head group 9 is The lifting oil cylinder 95 drives the first pressing block 96 to move up to loosen the left end of the elevator guide rail 2, and at the same time, the second lifting oil cylinder 63 of the fixed head group 6 drives the second pressing block 64 to move upward to release the right end of the elevator guide rail 2. Then make the left thrust oil cylinder 82 drive the left moving seat 8 and the twisting head group 9 to move to the left until the left end of the elevator guide rail on the guide rail feeding platform 3 is moved out of the first ⊥-shaped positioning hole 94 of the twisting head group 9, Stop the action of the left thrust oil cylinder 82, and at the same time make the right thrust oil cylinder 52 drive the right moving seat 5 and the fixed head group 6 to move to the right until the right end of the elevator guide rail on the guide rail feeding platform 3 moves out of the second ⊥ of the fixed head group 6 After forming the positioning hole 62, stop the action of the right thrust cylinder 52; then move the supporting centering mechanism 4 down until the corrected elevator guide rail 2 lifted by the supporting centering mechanism 4 falls on the guide rail feeding platform 3 again superior;
