Detailed ways

Below in conjunction with accompanying drawing, illustrate the specific embodiment of the present utility model.

As shown in Figures 1 to 4, a rotating structure for a longitudinal bone welding machine includes a revolving body 7, the upper part of the revolving body 7 is fixed to the large platform 8, and the lower part of the revolving body 7 passes through the walking platform 13 and is connected to the small platform 2 ; Between the walking platform 13 and the small platform 2, a slewing bearing 6 is also set, and the slewing bearing 6 is engaged with the gear 4, and the gear 4 is installed on the output end of the drive motor 1 through the baffle plate 5, and the drive motor 1 is connected to the small drive motor 1 through the motor mounting plate 3. Platform 2 is connected. The above-mentioned slewing bearing 6 includes an inner ring gear 62 and an outer ring gear 61, the inner ring gear 62 is fixedly connected with the small platform 2, and the outer ring gear 61 is fixedly connected with the walking platform 13. As shown in FIG. 2 , the revolving body 7 is also fixedly connected to one end of the rotating drag chain 12 , and the other end of the rotating drag chain 12 is fixedly connected to the walking platform 13 . An induction mounting plate 11 is also installed on the walking platform 13, and an induction switch 10 is installed on the induction mounting plate 11; an induction rod 9 is also installed on the rotary body 7.

Concrete work process of the present utility model is as follows:

During the welding process of marine jigsaw panels or offshore platform longitudinals, when it is necessary to switch from horizontal welding to longitudinal welding, the walking platform 13 remains still, and at this time the driving motor 1 is started, and the output end of the driving motor 1 drives the gear 4 to rotate. , because the gear 4 meshes with the outer ring gear 61 of the slewing bearing 6, and the outer ring gear 61 is fixedly connected with the walking platform 13, so when the output end of the driving motor 1 is rotating, the gear 4 and the slewing bearing 6 make the walking The platform 13 rotates, because the rotary body 7 runs through the walking platform 13, so the rotation of the walking platform 13 also drives the rotary body 7, and the small platform 2 and the large platform 8 connected to the rotary body 7 to rotate, and the arc guiding mechanism 14 is connected with the small platform 2 Also follow the rotation movement, when the rotary body 7 rotates 90°, the induction rod 9 on the rotary body 7 rotates to face the induction switch 10, triggers the induction switch 10 to start, and the induction switch 10 controls the drive motor 1 to stop working, thereby completing Center rotation operation of longitudinal bone welding machine.

The above description is an explanation of the utility model, not a limitation of the utility model. For the limited scope of the utility model, refer to the claims. Without violating the basic structure of the utility model, the utility model can be modified in any form.
