As shown in fig. 1, the turning mechanism of the winding machine comprises a driving handwheel driving device and a gearwheel 3, wherein the gearwheel 3 is coaxially sleeved on a main driving shaft 2 of the winding machine, and a fixing seat 7 of the driving handwheel driving device is sleeved on a housing 1 of the winding machine. As shown in fig. 2, one end of the fixing seat 7 is inserted into the winding machine housing 1, and the end of the fixing seat 7 located outside the winding machine housing 1 is fixedly connected to the winding machine housing 1 through a connecting bolt 11. The mounting axis of the fixed seat 7 is perpendicular to the corresponding connecting surface of the winding machine shell 1. The fixing seat 7 is provided with a transmission shaft penetrating through hole 72 along the axis thereof, and the transmission shaft 5 is sleeved in the transmission shaft penetrating through hole 72. Two ends of the transmission shaft 5 are respectively arranged at two sides of the winding machine shell 1.

The transmission shaft 5 can move relative to the fixed seat 7 under the action force of the driving hand wheel 6 along the axial direction, and further drives the small gear 4 at the other end to engage with and separate from the large gear 3. In addition, the small gear 4 can rotate along with the rotation of the driving hand wheel 6, when the small gear 4 and the large gear 3 are in a meshing state as shown in fig. 3, the large gear 3 also rotates along with the rotation, and therefore the main driving shaft 2 of the winding machine is driven to rotate, and the detection operation is achieved. The setting method improves the driving accuracy, reduces the working strength of workers, simultaneously enables the maintenance operation to be more convenient and reliable, and ensures the working safety. After the detection operation is finished, the worker can utilize the driving hand wheel 6 to perform reverse movement operation on the transmission shaft 5, so that the pinion 4 and the gearwheel 5 are separated, the influence of a driving hand wheel driving device on normal work of the winding machine is avoided, and the work safety is ensured. In order to ensure the transmission effect and the structural stability, as shown in fig. 1, the pinion 4, the transmission shaft 5 and the driving hand wheel 6 are coaxially arranged, the transmission shaft 5 is perpendicular to the main driving shaft 2 of the winding machine, the gearwheel 3 is arranged between the pinion 4 and the fixed seat 7, and at the moment, the gearwheel 3 and the pinion 4 are both left-handed gears. When the small gear 4 and the large gear 3 are in the engaged state as shown in fig. 3, the driving hand wheel 6 drives the transmission shaft 5 to rotate in the arrow direction as shown in the figure, and the corresponding large gear 3 rotates clockwise as shown in the figure.

In order to improve the structural stability of the gear engagement and separation operation, the transmission shaft 5 is respectively provided with an inner limiting step 51 and an outer limiting step 52 at two sides of the fixed seat 7. As shown in fig. 3, when the inner limiting step 51 moves toward the outside of the winding machine along with the transmission shaft 5 and reaches a position contacting with the fixed seat 7, the transmission shaft 5 stops moving under the blocking action of the inner limiting step 51. At this time, the small gear 4 and the large gear 3 are in a meshed state, the large gear 3 can rotate along with the rotation of the small gear 4, and the corresponding outer limiting step 52 moves to a position far away from the fixed seat 7 along with the transmission shaft 5.

outer limit steps

51 and 52 may be provided with an annular protruding ring or a circumferential protrusion to achieve a stable limit operation.

Meanwhile, the fixing base 7 is provided with a transmission shaft positioning structure toward the transmission shaft penetrating through hole 72 as shown in fig. 4. The drive shaft positioning structure includes a positioning pin 8 and a positioning moving groove 71. The axis of the positioning movement groove 71 is perpendicular to the axial direction of the transmission shaft 5, and the positioning movement groove 71 includes a rectangular movement groove 711 and an opening 712. The opening 712 is coaxially disposed at an outward port of the rectangular moving groove 711, the width of the opening 712 is smaller than the width of the rectangular moving groove 711, and the other end of the rectangular moving groove 711 is inserted into the through hole 72 toward the transmission shaft. The positioning end 81 of the positioning pin 8 is matched with the structure of the rectangular moving groove 711 and is positioned in the rectangular moving groove 711. The operation end 83 of the positioning pin 8 located outside the fixing base 7 is in a spherical shape with a diameter larger than the width of the opening 712. The operation end 83 and the positioning end 81 are connected to both ends of the operation rod 82 inserted through the opening 712. The positioning end 81, the operating rod 82 and the operating end 83 are coaxially arranged, and then the positioning end 81 and the operating rod 82 form a T-shaped structure as shown in FIG. 4. When the operation end 83 performs the movement in the axial direction, the positioning end 81 also performs the reciprocating movement along the rectangular moving groove 711 by the pulling action of the operation rod 82. The operating rod 82 is provided with a spring 9 between the opening 712 and the positioning end 81, and two ends of the spring 9 are respectively disposed on two opposite end surfaces of the opening 712 and the positioning end 81.

And when the positioning end 81 is positioned in the positioning ring groove 53, the actual length of the spring 9 is smaller than or equal to the natural length, thereby ensuring that the spring 9 always gives the positioning end 81 a force towards the transmission shaft 5. When outer spacing step 52 contacts with fixing base 7, location end 81 is located positioning ring groove 53 and then prescribes a limit to drive shaft 5 along the position of axial direction to in guaranteeing the normal work of coiling machine, pinion 5 can not contact with gear wheel 3, in order to guarantee job stabilization nature.

When performing the detection operation, the operator needs to change the driving handwheel driving device and the gearwheel 3 from the relative state in fig. 1 to the connected state in fig. 3. At this time, the worker firstly moves the operation end 83 of the positioning pin 8 away from the transmission shaft 5, and then drives the fixed end 83 to leave the positioning ring groove 53, and then moves the driving hand wheel 8 in the direction away from the winding machine, so that the corresponding pinion 4 and the transmission shaft 5 move in the same direction. When the inner limiting step 51 moves to contact with the fixed seat 7, the transmission shaft stops moving under the blocking action of the inner limiting step 51, and at the moment, the pinion 4 and the bull gear 3 are in a meshing state. The driving hand wheel 6 can realize the transmission operation of the large gear 3 so as to detect the winding machine. After the detection operation is finished, the turning mechanism is converted from the state shown in fig. 3 to the state shown in fig. 1, the transmission shaft 5 moves towards the inside of the winding machine along with the thrust of the driving hand wheel 6, and at the moment, the pinion 4 is gradually separated from the bull gear 3. When the positioning ring groove 53 moves to the corresponding position of the positioning end 81, the positioning end 81 moves to the inside of the positioning ring groove 53 under the action force of the spring 9, and due to the structural arrangement of the positioning ring groove 53, the deviation of the return angle generated in the rotating operation process of the transmission shaft 5 cannot influence the connecting effect of the positioning end 81 and the positioning ring groove 53, so that the structural connection quality is effectively ensured. At this time, the corresponding outer limit step 52 is in contact with the fixed seat 7, and the pinion 4 and the bull gear 3 are separated from each other and do not affect each other. At this time, the winding machine can perform normal operation.
