Embodiment Construction

[0025] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. figure 1 It is a sectional view showing the whole of a blind rivet fastening device according to an embodiment of the present invention. in addition, figure 2 and image 3 yes means figure 1 Partial sectional view of the front end of the blind rivet riveting device.

[0026] As shown in these figures, a hollow grab case 2 for accommodating blind rivets is provided at the front end of the blind rivet riveting device 1 , and a grab assembly 3 is provided at the front end of the grab case 2 . The gripping unit 3 has an insertion hole 6 for inserting the mandrel 5 of the blind rivet 4 . Such as figure 2 As shown, although the blind rivet 4 is composed of a rivet body 4a and a mandrel 5, as shown in image 3 As shown, the gripper assembly 3 is configured such that the front end of the gripper assembly 3 abuts the rivet main body 4 a, and only the mandrel 5 is accommo...

Abstract

The invention relates to a blind rivet fastening device. A steel ball is housed in a hole extending from the inner wall of the nose piece towards the outer wall and rearward obliquely with respect to a rivet insertion port. An elastic ring pushes the steel ball from the outer wall toward the inner wall so that a portion of the steel ball protrudes into the and holds the mandrel. Because the hole extends rearward obliquely with respect to the port, the steel ball can move easily when the mandrel travels in the insertion direction but has difficulty moving when the mandrel travels in the opposite direction. As a result, the steel ball keeps the mandrel from sticking out of the nose piece after fastening of a blind rivet, makes it easy to insert a new blind rivet in the nose piece, and keeps the inserted blind rivet from falling out before being fastened.

Description

technical field [0001] The invention relates to a blind rivet riveting device, in particular to a grasping assembly located at the front end of the blind rivet riveting device. Background technique [0002] The blind rivet riveting device is provided with: a hollow grasping shell for accommodating blind rivets; a grasping assembly is arranged at the front end of the grasping shell and has an insertion hole for inserting the mandrel of the blind rivet; jaw cover , which is adjacent to the rear of the grabbing assembly and is arranged in the grabbing housing so that it can move forward and backward, and has an inner peripheral surface whose inner diameter becomes smaller toward the front end; the jaws are arranged in the jaw sleeves for grasping and inserting into the The mandrel of the blind rivet inserted through the hole, and has an outer peripheral surface that is slidably in contact with the inner peripheral surface of the jaw sleeve; Squeeze the jaws forward. By moving...
