[0039] Working principle: When in use, first, one end of the pick 18 is inserted into the circular tube 15, and then the two threaded rods 16 are rotated, so that both threaded rods 16 are in threaded transmission with the circular tube 15. At the same time, the two threaded rods 16 respectively drive the two clamping plates 17 to move and clamp the pick 18.

[0040] After that, the circular plate 3 is driven by the first motor 19 to rotate inside the first annular plate 2.

At the same time, the first fixing rod 4 drives the first transmission rod 6 to rotate. At the same time, the first transmission rod 6 drives the universal joint 7 to rotate. At the same time, the universal joint 7 drives the second transmission rod 8 to rotate on the second annular plate 9. At the same time, the second transmission rod 8 drives the circular tube 15 to rotate, so that the circular tube 15 drives the pick 18 to rotate, and further the cladding device 23 performs the cladding processing on the pick 18.

[0041] Meanwhile, the drive of the cylinder 20 causes the rack 21 to move downward and mesh with the corresponding second gear 13.

At the same time, the worm gear 11 drives the corresponding second fixing rod 10 to rotate on the corresponding first fixing plate 14. At the same time, the action of the two second fixing rods 10 causes the second ring plate 9 to rotate by a certain angle. At the same time, the second ring plate 9 drives the second transmission rod 8 to rotate synchronously by a certain angle. At the same time, the second transmission rod 8 drives the pick 18 to tilt by a certain angle through the action of the round tube 15, so as to achieve the effect of angle adjustment of the pick 18;

[0042] After the machining of the pick 18 is completed, first restore the cylinder 20 to its original state, then start the first motor 19 to make the circular plate 3 rotate, and move the machined pick 18 to the position corresponding to the box door 25. Then open the box door 25 to take out the machined pick 18. At the same time, move another pick 18 to the position corresponding to the cladding device 23 and make the corresponding first gear 5 mesh with the third gear on the second motor 22, so as to achieve the effect of automatic switching of the pick 18 without stopping the machine;

[0043] The technical progress obtained by the present utility model compared with the prior art is that through the cooperation of each component, not only can the automatic switching of the pick 18 be achieved without stopping the machine, improving the processing efficiency, but also the angle adjustment of the pick 18 can be realized, improving the cladding effect of the pick 18.
