Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing equipment, and in particular relates to a columnar barrel processing positioning device. Background Art

[0002] During lathe processing, due to certain needs, the cylindrical cylinder needs to be divided into several metal rings with a certain width through a turning tool. The cylindrical cylinder is clamped on a clamping table that can be displaced forward and backward, left and right, and rotated through a three-jaw self-centering chuck. The cylindrical cylinder is driven to rotate around the axis by the rotation of the clamp. The positioning component is used to control the amount of displacement of the clamp seat and the cylindrical cylinder toward the turning tool, which ultimately determines the width of the metal ring.

[0003] It is difficult for the existing positioning assembly to make direct contact with the rotating cylindrical barrel. The reason is that friction will always occur after the end of the rotating cylindrical barrel contacts the positioning assembly. That is to say, after the cylindrical barrel is cut by the turning tool, the cylindrical barrel needs to stop rotating and then move one end of the cylindrical barrel toward the turning tool to contact the positioning assembly. The rotation needs to be stopped frequently, which seriously affects the processing efficiency.

[0004] Based on the deficiencies in the prior art, the utility model discloses a cylindrical barrel processing positioning device, including a U-shaped seat and a roller. When the rotating cylindrical barrel displaces to the right, after the right end of the cylindrical barrel contacts the roller, the roller can follow the rotation. While achieving positioning, the friction on the right end of the cylindrical barrel is reduced, and there is no need to stop the rotation of the cylindrical barrel around the axis, thereby ensuring processing efficiency.

[0027] When the cylindrical body is first split, the lathe clamping table 14 is moved rightward, driving the three-jaw self-centering chuck 13 and the cylindrical body to move rightward. The three-jaw self-centering chuck and the cylindrical body are always in a state of rotation around the axis. When the right end of the cylindrical body contacts the roller, the roller is driven to rotate accordingly to achieve width positioning of the cylindrical body. Then, the lathe clamping table is moved forward to make the rotating cylindrical body slowly approach the turning tool 7 to achieve cutting of the cylindrical body, cutting out a metal ring of a certain width, and then the lathe clamping table is moved backward to cut the metal ring. The cylindrical body is moved back to the left side of the roller, and the lathe clamping table is moved right again. When the right end of the cylindrical body contacts the roller, the roller is driven to rotate to achieve the width positioning of the cylindrical body again.
