Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 3, the rotating shaft inner lock structure of the welding and polishing machine is applied to a station switching device of the welding and polishing machine, the station switching device comprises a rotating disc 1 for switching the position of a workpiece, a connecting hole 2 is formed in the center of the rotating disc 1, the structure comprises a shaft body 3 and a cover body 4, a cover hole 5 is formed in the end surface of the shaft body 3, four first locking holes 6 are formed in the peripheral wall of the cover hole 5 in a penetrating manner, a straight line where the four first locking holes 6 are located forms a virtual cross, locking tongues 7 are slidably arranged in the first locking holes 6, second locking holes 8 are formed in the peripheral wall of the connecting hole 2, the number and the positions of the second locking holes 8 correspond to the first locking holes 6, parts of the locking tongues 7 can be introduced into the second locking holes 8 from the first locking holes 6 to complete the fastening of the shaft body 3 and the rotating disc 1, guide inclined planes 9 are arranged at the inner ends of the locking tongues 7, locking blocks 10, the cover body 4 is completely covered on the shaft body 3, the locking block 10 is located in the cover hole 5, four sides of the bottom surface of the locking block 10 are provided with straight chamfers 11, inclined planes formed by the straight chamfers 11 are the same as the guide inclined planes 9 of the four locking tongues 7, the upper surface of the inner end of each locking tongue 7 is also provided with a pull-back hole 12, and the bottom surface of the locking block 10 is provided with a pull-out pin 13 with the size being the same as that of the pull-back hole 12.

After the shaft body 3 and the turntable 1 are fixedly connected, the shaft body 3 is rotatably connected to a base, the turntable 1 can rotate relative to the base by taking the shaft body 3 as the center, and the shaft body 3 needs to be detachable relative to the turntable 1 because the front side and the back side of the turntable 1 can be used.

In normal times, because the cover 4 has a certain weight, it will be pressed more tightly above the turntable 1, and when it needs to be detached, the cover 4 is detached from the shaft 3, and for the convenience of detachment, the applicant can provide an implementation idea: it is preferable to design the upper surface of the cover 4 with a layer of magnetic material and then suck the cover 4 by an electromagnet, or to design a detachable hole above the cover 4 to facilitate prying.

Then, the cover body 4 itself can be used as a tool, the pull-out pin 13 designed on the cover body is hooked into the pull-back hole 12, after the locking tongue 7 is pulled out from the second locking hole 8, the shaft body 3 and the rotary disc 1 are not tightly fixed any more, then the reverse surface of the rotary disc 1 is sleeved into the shaft body 3 again for alignment, the cover body 4 is covered, and under the interaction of the straight chamfer 11 on the bottom surface of the locking block 10 and the guide inclined surface 9 of the locking block 10, the periphery of the cover body is expanded outwards until the cover body extends into the second locking hole 8 to complete the fastening of the rotary shaft and the shaft body 3 again.
