The screw 1 4 is located on a plane perpendicular to the plane of the guide rail 15, the nut 17 and the guide block 16 are fixed to the right-angle slide 29, the two planes of the right-angle slide 29 are perpendicular, the horizontal frame 2 is fixed to the right-angle slide 29, so that the horizontal frame 2 can slide up and down on the bracket 3, a bracket gripper 24 is installed at the front end of the horizontal frame 2, and a material frame 25 is arranged on the bracket gripper 24; through the combination of the lead screw and the nut, the rotary motion converts the rotary power into a linear motion, the coupling between the nut and the lead screw makes the nut move linearly along the lead screw when the lead screw rotates, and the position and force of the motion are controlled by changing the angle or speed of rotation, thereby achieving precise adjustment, and the height of the horizontal frame is precisely adjusted by the lead screw and the guide block in combination with the lifting servo motor and the reducer 2, so as to achieve precise feeding and taking of materials.

[0026] The PLC controller 30 uses a remote I / O module to realize input and output, including an output module, an input module and a communication module. The output module is connected to the servo motor 10 and the lifting servo motor 11, the input module is connected to the sensor 23 and the proximity switch 22, and the communication module is connected to the upper computer automation control system.

[0027] like Figure 5 As shown, an accordion cover 18 is arranged above the bracket 3, and a motor protection cover 19 is connected above the accordion cover 18; an accordion cover 20 is arranged at the starting end of the driving mechanism above the track trolley 1; a stop block 21 is arranged at the terminal end of the driving structure above the track trolley 1; a support plate 26 is arranged below the top plate of the track trolley 1, and a proximity switch 22 and a sensor 23 are arranged on the right side of the bracket 3; the accordion cover 1 and the motor protection cover can prevent the heat source from radiating heat to the driving mechanism after the heating furnace door is opened, causing damage; the bracket is limited by the stop block to prevent the bracket from falling out of the track trolley when moving, causing an accident; the support plate plays a reinforcing role to prevent deformation under load-bearing conditions.

[0028] Technical parameters and materials: The lifting height is 0.7 meters, the moving distance is 1.55 meters, the servo motor power is 1.5KW, and the total weight of the horizontal frame is 30Kg; the bracket gripper is made of heat-resistant stainless steel 310S, and the bracket is made of Q235. In order to reduce the overall weight, three-sided punching process is performed.

[0029] Working principle:

[0030] Loading and furnace loading process: The crane places the sample and material frame 25 on the bracket gripper 24 of the horizontal frame 2, and the servo motor 10 and reducer 19 of the driving mechanism drive the bracket 3 to move from the origin position toward the resistance furnace through the guide rail slide 5, rack 6 and slider 7. At the same time, the lifting servo motor 11 and reducer 2 12 of the lifting mechanism raise the horizontal frame 2 through the guide rail 15 and the screw rod 14. The base plane of the material frame 25 lifted by the bracket gripper 24 is slightly higher than the bottom plate plane of the resistance furnace. The bracket 3 moves to the front end limit, and the material frame 25 is lifted into the furnace. The lifting mechanism moves downward to drive the horizontal bracket 2 and the bracket gripper 24 to descend. After leaving the material frame 25, the driving mechanism moves from the terminal limit to the origin direction, and the movement stops after reaching the origin, completing the loading and furnace loading process.

[0031] The process of taking out the furnace: the servo motor 10 and the reducer 19 of the driving mechanism drive the bracket 3 to move from the origin position toward the direction of the resistance furnace through the guide rail 5, the rack 6 and the slider 7. At the same time, the lifting servo motor 11 and the reducer 2 12 of the lifting mechanism make the upper plane of the bracket gripper 24 of the horizontal frame 2 slightly lower than the lifting plane of the material frame 25. After the bracket 3 moves to the front end limit, the bracket gripper 24 of the horizontal frame 2 extends under the lifting plane of the material frame 25. The guide block 16 and the nut 17 of the lifting mechanism rise to drive the bracket gripper 24 and the material frame 25 of the horizontal frame 2 to rise until the material frame 25 is separated from the bottom plate of the resistance furnace. The driving mechanism runs toward the origin, driving the horizontal bracket 2, the bracket gripper 24 and the material frame 25 away from the resistance furnace. After reaching the origin, the driving mechanism stops moving, and the process of taking out the furnace is completed.
