Technical Field

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

[0002] Turning is a method of cutting a workpiece on a lathe by rotating the workpiece relative to the tool. Turning is the most basic and common cutting method and plays a very important role in production. Turning is suitable for machining rotating surfaces. Most workpieces with rotating surfaces can be machined by turning, such as internal and external cylindrical surfaces, internal and external conical surfaces, end faces, grooves, threads and rotating forming surfaces. The tools used are mainly turning tools.

[0003] During the frame turning process, the circular frame needs to be placed in the lathe. In order to improve the turning efficiency, the positioned frame is grabbed by a robot and placed in the lathe. In order to improve the accuracy of the robot placement, a positioning device is needed to position the frame before the robot grabs it to improve the subsequent processing accuracy. Therefore, a frame turning positioning device is needed. Utility Model Content
