Description

A device for marking the center of the workpiece}

The present invention relates to a center marking device for a processing object. More specifically, when drilling the axial center of a processing object is required, the axial center of the processing object can be accurately marked before drilling, It relates to a center marking device for processing objects that is built to automatically perform continuous marking on multiple processing objects.

Generally, machine tools such as lathes are used to process objects including bolts. At this time, one end of the object to be processed is fixed to the chuck, and the other end is supported and pressed by the tailstock.

At this time, in order to process the object to be processed more accurately, the tailstock must press the exact center of one side of the work object. For this reason, a groove is formed in the center of one side of the workpiece, and a tailstock is coupled to this groove to apply pressure. Various types of centering devices are used for this purpose.

One of the conventional centering devices is typically using the tailstock of a lathe. More specifically, the tailstock is set to match the center of the chuck, and the operator manually moves the tailstock to the workpiece whose end is fixed to the chuck. The center is marked, and when the processing object is pressed, the tailstock supports the marked center portion.

However, when center marking work is required for multiple processing objects, the operator must individually mark each processing object manually, and as the marking progress time increases, the time required for the work significantly increases. There was also a problem of decreased productivity.

In order to solve this problem, a technology for a device that can ensure work convenience through a carriage that can automatically move the processing object to the tailstock side has been proposed. However, in the case of the prior art, only one processing object is After marking is completed, the problem that workers must individually place the processing objects that require marking still exists.
