Abstract
A self-piercing die riveter having an indexable die table on the nose of its frame. The die table has a number of dies disposed thereon. The frame defines a first passage and a second passage in communication with and diverging from the first passage. An actuator for indexing the die table is located on the riveter outside of the nose of the frame and is connected to the die table through either shafts or belts disposed within the first and second passages. The die table has a number of detents that cooperate with a locating arm to hinder indexing of the die table and position the dies in-line with the path of a reciprocating punch.
Claims19
A self-piercing die riveter comprising:
- a frame, secured to a robotic arm, supporting a die table having a plurality of dies, the frame defining a first passage extending along an axis of rotation of the die table and a second passage in communication with and diverging from the first passage;
- and
- an actuator, secured to the frame adjacent to the second passage, configured to rotate the die table through the first and second passages.
A die riveter comprising:
- a frame, having an internal portion and an external portion, secured to a robotic arm;
- a die table rotatable on an axis and disposed on the internal portion of the frame;
- a plurality of dies disposed on the die table;
- a first shaft connected to and extending along the axis of the die table;
- a second shaft coupled to and extending in a diverting direction from the first shaft;
- and
- an actuator, secured to an external portion of the frame, connected to the second shaft and capable of rotating the die table through the first and second shafts.
A riveter comprising:
- a C-shaped frame defining a head, a nose, and a central section disposed between the head and the nose, the C-shaped frame secured to a robotic arm at the central section;
- a die table supported by the nose and defining a number of detents;
- a first die disposed on the die table corresponding to a first detent of the number of detents;
- a second die, having a geometry different than the first die, disposed on the die table corresponding to a second detent of the number of detents;
- a locating arm connected to the riveter having a free end selectively disposable in the first and second detents to hinder indexing of the die table and position the first and second dies in-line with a path of a reciprocating punch, the reciprocating punch supported by the head;
- and
- an actuator supported by the central section, the actuator capable of indexing the die table advancing the free end of the locating arm to be selectively disposed in any one of the number of detents and position a corresponding die in-line with the path of the reciprocating punch.
