Embodiment approach 1

[0058] The friction stir point welding apparatus according to Embodiment 1 includes: a pin member formed in a cylindrical shape; a shoulder member formed in a cylindrical shape through which the pin member is inserted; and a rotary driver that rotates the pin member and the shoulder member. The axis that coincides with the axis of the pin member rotates; and the advance and retreat driver makes the pin member and the shoulder member move forward and backward along the axis respectively, and a slot 1.

[0059] Hereinafter, an example of the friction stir point welding device according to Embodiment 1 will be described in detail with reference to the drawings.

Deformed example 1

[0129] Next, a modified example of the friction stir point welding apparatus according to Embodiment 1 will be described.

[0130] The friction stir spot welding device according to Modification 1 of Embodiment 1 is the friction stir point welding device according to Embodiment 1, in which a second groove is formed on the front end surface of the shoulder member so as to extend in the radial direction.

Embodiment approach 2

[0137] The friction stir point welding apparatus according to Embodiment 2 includes: a pin member formed in a cylindrical shape; a shoulder member formed in a cylindrical shape through which the pin member is inserted; and a rotary driver that rotates the pin member and the shoulder member. The pin member rotates on the same axis as the axis; and the advance and retreat driver moves the pin member and the shoulder member forward and backward along the axis respectively, and a second groove is formed on the front end surface of the shoulder member to extend radially.

[0138] Below, refer to Figure 7 and Figure 8 , an example of the friction stir point welding device according to Embodiment 2 will be described in detail. In addition, since the operation of the friction stir spot welding device according to Embodiment 2 is basically the same as the operation of the friction stir point welding device according to Embodiment 1, detailed description thereof will be omitted.

Abstract

A joining device for friction stirring points according to the present invention is provided with: a pin member (11) formed in a columnar shape; a shoulder member (12) which is formed in a cylindrical shape and into which the pin member (11) is inserted; a rotation driver (57) for rotating the pin member (11) and the shoulder member (12) around an axis line (Xr) that corresponds to the axial center of the pin member (11); and a forward-and-backward driver (53) for moving the pin member (119) and the shoulder member (12) forward and backward along the axis line (Xr), a first groove (21) being formed at the tip of the outer peripheral surface of the shoulder member (12) so as to extend along the axial-center direction of the pin member (11).

Description

technical field [0001] The present invention relates to a friction stir point welding device, an object to be joined obtained by performing friction stir point welding, and a shoulder member. Background technique [0002] For conveying equipment such as automobiles, railway vehicles, and aircraft, resistance spot welding or riveting is used to join metal materials. However, in recent years, a method of joining metal materials using frictional heat (friction stir point joining method) has attracted attention (for example, refer to Patent Document 1). [0003] In the friction stir point joining method disclosed in Patent Document 1, a substantially cylindrical pin member and a substantially cylindrical shoulder member having a hollow into which the pin member is inserted are used to join objects to be joined, such as As shown below, the tool drive unit that operates (drives) the pin member and the shoulder member (rotary tool, joining tool) is controlled. [0004] That is, w...
