Field of the Invention [0001] The present invention relates to a riveting machine used for manufacturing small parts, and more particularly, to a riveting machine used for manufacturing a single part or a part, A riveting machine for manufacturing parts that is configured to move from a setting position to a riveting position and to perform an riveting operation at a moving position by a part setting position for supplying and fixing the base material and a material and a riveting position for press driving .

Generally, in a part formed by riveting a material on a base material, an operator holds the riveting gun directly, sets a rivet, and operates a gun to operate the combination.

The riveting gun has been developed and used variously, such as manual type of leverage principle, air type using compressed air, and electric type using electric motor.

However, when riveting is performed by using such a hand tool, when a worker carries out a work by switching work of holding and handing a hand tool again while performing a work, material, and rivet setting work, productivity is remarkably decreased And at the same time, there arises a problem that the riveting quality is not uniform, and the worker is caused to repeatedly work, resulting in a decrease in work efficiency and an increase in fatigue.

Although automatic rivets of various structures have been proposed, it is preferable to introduce dedicated equipment in the case of repeatedly producing many parts together with a disadvantage that it takes up a large area of the equipment. However, In the case of producing certain parts as well as other types of parts, it is impossible to introduce dedicated equipment.

On the other hand, according to the "riveting machine for gas container valve" in Korean Utility Model Publication No. 1990-10476, the same circumferential multiple valve fixing jig 21 of the indexing table 20, which rotates at a certain angle by the control of the full- The indexing table 20 and the drilling machine 20 are installed at predetermined angles so that the drilling machine 30 and the air hammer 40 are opposed to each other and the indexing table 20 and the drilling machine 30 and the air hammer 40 are sequentially operated under the control of the electric field section.

Such conventional techniques are useful as small unit facilities different from the above-mentioned dedicated equipment. However, since the electric field control for index drive is complicated and the repetition of drilling and pressing is repeated, the stop position clearance (backlash) There is a problem that the durability of the device itself is weak.
