Embodiment Construction
[0025] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0026] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0027] like Figure 1 to Figure 3 As shown, the present invention provides a floating riveter head structure suitable for robot riveting, including: a main body 100, a riveting rod 200 that moves along the length direction of the main body 100 is arranged inside the main body 100, and the main body 100 Th...

The invention provides a riveter head floating mechanism suitable for robot riveting, and belongs to the technical field of riveting equipment. The riveter head floating mechanism comprises a body, and a rivet pulling rod moving in the length direction of the body and a floating structure driving the rivet pulling rod to move and reset in the horizontal direction are arranged in the body; and a ball head structure horizontally moving along with the rivet pulling rod is connected between the floating structure and the rivet pulling rod, and the floating structure comprises an elastic piece arranged in the axis direction of the rivet pulling rod. According to the riveter head floating mechanism suitable for robot riveting, the floating mechanism provided with an elastic body is arranged in the body, so that when a riveter and a hole site have small-amplitude deviation, the rivet pulling rod can generate small-amplitude deviation in the radial direction of the floating mechanism along with the ball head structure, and the situation that a riveter cannot be inserted into a hole site or a rivet is not attached to the surface of a product after being inserted into the hole due to inaccurate hole alignment is avoided.
Description
technical field [0001] The invention belongs to the technical field of riveting equipment, and in particular relates to a floating structure of a riveting gun head suitable for robot riveting. Background technique [0002] Riveting, that is, rivet connection, is a method of using axial force to thicken the nail rod in the rivet hole of the part and form a nail head to connect multiple parts. [0003] At present, in industrial production, robotic riveting or automatic assembly riveting guns are mostly used for riveting operations. However, the riveting guns on the market often fail to insert the rivet nut into the hole due to inaccurate hole alignment, or the flange surface of the rivet nut is in contact with the hole after being inserted into the hole. The surface of the product does not adhere. [0004] A Chinese patent with the announcement number CN206009620U discloses an automatic riveting mechanism, which at least includes: a bending-resistant C-shaped frame, a positio...
