Description

Technical Field

[0001] This invention relates to the field of CNC lathes, specifically to a CNC lathe loading and unloading device for adjusting workpieces. Background Technology

[0002] CNC lathes are among the most widely used CNC machine tools. They are mainly used for cutting and machining internal and external cylindrical surfaces, internal and external conical surfaces with arbitrary cone angles, complex rotating internal and external curved surfaces, and cylindrical and conical threads on shaft-type or disc-type parts. They can also perform grooving, drilling, reaming, boring, and other machining operations. Therefore, the materials processed on CNC lathes are mostly basic shapes such as cubes, cuboids, cylinders, cones, and hemispheres. While the basic shapes of the materials are relatively symmetrical and simple, many alloy parts require initial positioning during machining. Sometimes, a single material may have been fused with multiple materials in a previous process. Therefore, the machining sequence is crucial, requiring layer-by-layer machining from top to bottom or progressing from a specific direction. Consequently, intelligent robotic arms are often used to adjust the material to a suitable position before it enters the clamping station of the CNC machine tool, using the marked position as the initial point for machining.

[0030] The regulator is externally equipped with several sets of conveyor belts 310 that can rotate evenly, and the regulator is externally equipped with a flipping structure that can drive the conveyor belts 310 to flip at an even angle. The conveyor belts 310 are internally equipped with conveyor rollers, and the conveyor rollers are internally equipped with motors.

The rotating conveyor belt 310 adjusts the horizontal direction, and the adjuster flips to adjust the vertical direction of the material, thereby adjusting the material to the correct placement position.

[0033] Specifically, the identifier 2 includes a housing 21, with a sleeve 22 on the upper surface of the housing 21. A positioning strip 23 is welded to the inner surface of the sleeve 22. A screw 24 is engaged inside the sleeve 22. Nuts 25 are screwed to both the top and bottom of the screw 24. A lifting frame 26 is mounted on the bottom of the screw 24. Cameras 27 are mounted on the bottom of the lifting frame 26 and the upper surface of the center of the housing 21. The cameras 27 can take supplementary photos of the corresponding positions and obtain the orientation and position of the existing materials after image recognition processing. By comparing with the qualified material orientation, the adjustment plan is directly calculated.

Therefore, only one power source is needed to drive the entire system to rotate synchronously in the same direction. This type of adjuster has a compact structure, high utilization rate, and is suitable for adjusting smaller materials.

[0038] Specifically, the rotary joint includes a first rotary joint 4, the first rotary joint 4 includes a first fixed tube 41, the outside of the first fixed tube 41 is fitted with a first wire 43, the inside of the first wire 43 is fitted with a first elastic first adhesive piece 42, the inner side of the first adhesive piece 42 is tightly fitted with a first electrical contact ring 44, the inside of the first electrical contact ring 44 is fitted with a first central shaft 45, the inner side of the first electrical contact ring 44 passes through the first central shaft 45 and is fitted with a second wire 46, and the second wire 46 is connected to the first motor 39;

[0039] When the first rotary joint 4 is in use, the external first fixed tube 41 will not rotate.
