Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

Referring to FIG. 1 , the automatic tool loading system is characterized in that it includes a straight arm tool changing device 100 and a tool pushing device 200 .

The straight-arm tool changing device includes a base 110 with a guide rail, and a bracket assembly arranged on the base and capable of linear movement along the guide rail. The bracket assembly is connected with a hydraulic motor, which drives the bracket assembly to move linearly along the guide rail. The bracket assembly includes a lower bracket 121 and an upper bracket 122 , the upper bracket is connected with the lower bracket through a rotating reset device, and the upper bracket 122 can rotate relative to the lower frame 121 . Both sides of the upper bracket are respectively provided with a group of bracket cutter shaft groups 130, and the bracket cutter shaft group includes upper and lower two cutter shafts 131, corresponding to the upper and lower cutter shafts of the disc; in order to make the center of the upper and lower cutter shafts The centers of the upper and lower cutter shafts of the disc shearing machine are coincident, and the cutter shafts of the bracket cutter shaft group are provided with adjustment devices. In order to ensure the concentricity between the upper and lower cutter shafts and the upper and lower cutter shafts of the disc shearing machine, guide keys are installed at the ends of the cutter shafts of the bracket cutter shaft group, and copper bushings are also installed inside.

The knife pushing device 200 includes a fixed frame 210 with a slide rail, a movable frame 220 which is arranged on the fixed frame and can move linearly along the slide rail. sports. The moving frame is provided with a pushing tool frame 230 and a pulling tool frame 240 . The pushing knife frame 230 is fixedly arranged on the moving frame 220, the pulling tool frame can be lifted and lowered on the moving frame by a lifting device 250, and the pulling tool frame is arranged in front of the pushing tool frame. The lifting device includes an elastic reset member. The push tool frame is used to push the disc blade of the disc shears onto the bracket cutter shaft group of the straight arm tool changer, and the pull tool frame is used to push the disc blade on the bracket knife shaft group onto the disc shears.

See Figures 2, 3, 4, and 5. When in use, the moving frame drives the push knife frame to move forward, and the push knife frame pushes the disc blade of the disc shears onto the bracket knife shaft group of the one-arm tool changer. Rotate the upper bracket of the one-arm tool changer to switch the pre-installed blade to the feeding position, then lower the broach frame through the lifting device, and drive the broach frame to move backward through the moving frame until the bracket knife shaft is assembled The upper disc blade is pushed onto the disc scissors, then the lifting device raises the broaching tool frame, and the bracket assembly of the straight arm tool changer returns.
