The transverse adjusting mechanism 2, the longitudinal sliding table 3, the fixing and rotating mechanism 5, the bending cylinder 108 and the swing positioning cylinder 106 are connected with external control equipment, and automatic action can be realized.
Principle of operation
The longitudinal sliding table 3 can enable the bending head 1 to slide along the Z-axis direction of the main body 7, so that the whole mechanism is controlled to ascend and descend, and the train sensor is ensured to be compatible with train sensors with all thicknesses. The transverse adjusting mechanism 2 can enable the bending head 1 to move along the X axis of the main body 7, and the device can be compatible with all train sensors in the X direction. The self-adaptive bend 1 can realize automatic alignment and automatic bending of the stop washer 402, and the stop washer 402 needs to be respectively folded from two sides, so the self-adaptive bend 1 in two directions is adopted to simultaneously operate. The sensor holder 4 is used for fixing the sensor, and the fixing and rotating mechanism 5 is used for fixing and automatically rotating the sensor holder 4.
After the sensor frame 4 is fixed, the position of the transverse adjusting mechanism 2 is adjusted, the longitudinal sliding table 3 drives the self-adaptive bending head 1 to descend, the fixing finger 101 contacts the stop gasket 402, and at the moment, the fixing finger 101 is not in contact with the hexagon nut 401. The driving rack 109 is installed in the upper guide groove of the bent fixed side plate 110 to be movable back and forth along the guide groove. The bending cylinder 108 extends out to drive the transmission rack 109 to drive the large gear 1031 to rotate, the large gear 1031 rotates to drive the small gear 132 to be meshed with the racks on the bending fingers, and the clamping force between the fixing fingers 101 and the bending fingers 102 can be increased through transmission. The bending fingers 102 are installed in the lower guide grooves of the bending fixed side plates 110 to be movable back and forth therealong. The bending finger 102 is driven by the pinion 132 to contact one side of the pre-bent stopper pad 402. The inner side of the fixing finger 101 is designed with a guide surface conforming to the size of the hexagon nut 401, and three sides of the fixing finger can abut against the hexagon nut 401. At this time, the bending cylinder 108 continues to extend, and the bending finger 102, due to having contacted the stop washer 402, drives the bending fixed side plate 110 and all the components mounted thereon to move to the other side on the translational spring rod 107, thereby compressing the translational spring 104 and enabling the fixed finger 101 to approach the hexagon nut 401.
The swing positioning cylinder 106 and the swing reset spring rod 111 are arranged on the swing spring frame 105, the translation spring rod 107 and the translation spring 104 are arranged on the translation spring frame 112, and the translation spring frame 112 can rotate relative to the swing spring frame 105.

When bending operation is performed, the swing positioning cylinder 106 drives the swing positioning block 113 to leave the V-shaped groove on the translation spring holder 112.
When the guide surface of the fixed finger 101 contacts with one side of the hexagon nut 401, under the clamping force, the side of the hexagon nut 401 applies a reaction force of a part of the component force of the clamping force to the guide surface of the fixed finger 101, so that the translation spring holder 112 rotates relative to the swing spring holder 105, and when the relative rotation is generated, the square block on the translation spring holder 112 compresses the swing return spring rod 111. After swinging a certain angle, the three guide surfaces of the fixed finger 101 all abut against the three surfaces of the hexagon nut 401, and the bent fixed side plate 110 also stops moving on the translation spring rod 107. The bending cylinder 108 continues to extend, and all the clamping force of the bending fingers 102 acts on the pre-bent edge line of the stop washer 402, so that the stop washer 402 is folded along this edge line until it is completely pressed flat against the other side of the hexagon nut 401.
After the bending operation, the bending cylinder 108 retracts, the translational spring 104 pushes the bending fixed side plate 110 back to the original position, the swing reset spring rod 111 pushes the translational spring frame 112 back to the middle position, and in order to ensure accurate angle centering, the swing positioning cylinder 106 extends out, and the swing positioning block 113 is wedged into a V-shaped groove on the translational spring frame 112.
The sensor holder 4 is mounted on the fixed and rotating mechanism 5 and the above-described actions are repeated until all the stop washers 402 are folded.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
