[0025] Each of the robot mechanisms includes: a U-shaped frame 11 having two free ends respectively provided with a first cylinder 12, two first cylinders 12 being oppositely disposed, and two first cylinders 12 The power output end is provided with a first clamping plate 16, and a surface of the first cylinder 12 adjacent to the inner bottom surface of the U-shaped frame 11 is provided with a limiting plate 14, and the inner bottom surface of the U-shaped frame 11 is mounted with a second cylinder 13, a second cylinder 13 is provided with a first push plate 15 at the power output end, and further includes a third cylinder 18 for pushing and pulling the U-shaped frame 11 forward or backward, and a fourth cylinder 17 for lifting the U-shaped frame 11 and the third cylinder 18; The combined manipulator intelligently replaces the waxing work from manual to mechanical, efficient, low cost and highly automated. The gripping device includes a rotating arm 31 and a rotating electric motor 33. The power output end of the rotating electric machine 33 is fixed to one end of the rotating arm 31, and the other end of the rotating arm 31 is provided with a second clamping plate 34, and further includes a fixed arm 31. The fifth cylinder 32 and the fifth cylinder 32 power output end are provided with a third clamping plate 35 that cooperates with the second clamping plate 34. In the ring wax extracting machine of the embodiment, the rotating arm 31 is a rotating arm 31 having a U-shaped cross section, the fifth cylinder 32 is fixed in the rotating arm 31, and the second clamping plate 34 and the third The splint 35 is disposed laterally, and the power output rod of the fifth cylinder 32 passes through the bottom of the rotating arm 31 and is connected to the third clamping plate 35. The ring wax removing machine of the embodiment is provided with the rotating arm 31. There is a blowing pipe head 36 for blowing the removed ring wax a2; a ring wax removing machine according to the embodiment further includes a lifting platform 23, and the third cylinder 18 is fixed on the lifting platform 23, The power output end of the fourth cylinder 17 is connected to the bottom surface of the lifting platform 23.

[0026] Specifically, generally used in conjunction with a conveyor belt, the conveyor belt is located between the two sets of manipulator structures, firstly the wax pattern is transmitted over the conveyor belt, and then the wax pattern is transmitted by the plane of the vertical transmission belt. After the mode, and then between the two manipulator structures, the manipulator mechanism is in the initial stage. In the initial stage, the U cylinder 11 is first dropped, the first cylinder 12 is first retracted, the second cylinder 13 is retracted, and the third cylinder is retracted. 18 Retraction; When the wax pattern a reaches the working area position, it can be determined by sensors such as proximity switches, the conveyor belt stops before the east three cylinders push the U-shaped frame 11 forward, and the two U-shaped frames 11 move forward, so that The wax pattern a is located between the four limit plates 14, and then the first cylinder 12 is activated, the wax molds a1 are clamped by the first jaws 16, and then the fourth cylinders 17 lift them up, and the third cylinders 18 are U.
