Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] refer to Figure 1-Figure 8 , a friction stir welding positioning device for large plates, including a base 1, the base 1 has a working platform 2, and one side of the working platform 2 is provided with a reference turning arm 3 lower than the working platform 2, so The reference turning arm 3 is provided with a reference plate 4, the reference turning arm 3 is connected with a reference turning mechanism, and the benchmark turning mechanism drives the turning of the benchmark turning arm 3, so that it is in the reference state or on standby. State, when the reference turning arm 3 is in the reference state, its reference plate 4 is flatly laid on the working platform 2 after the turning arm 3 turns over, and when the turning arm 3 is in the standby state, the turning arm 3 leaves the working platform 2 after turning over, th...

Abstract

The invention discloses a friction stir welding positioning device for large plates. The device comprises a base; the base is provided with a working platform; a reference mechanism lower than the working platform is arranged on one side of the working platform; a left longitudinal frame higher than the working platform is arranged on the left side of the working platform; a right longitudinal frame higher than the working platform is arranged on the right side of the working platform; a left pressing mechanism is arranged on the left longitudinal frame; and a right pressing mechanism is arranged on the right longitudinal frame. The friction stir welding positioning device for the large plates can perform the friction stir welding on the large plates after positioning.

Description

technical field [0001] The invention relates to a positioning device for friction stir welding of large plates. Background technique [0002] If traditional welding methods such as submerged arc welding are used for welding large plates (such as road signs, etc.), it is very easy to produce defects at the welds, or cracks at the welds after a long period of use. If friction stir welding is used, the above disadvantages can be avoided, but the alignment and positioning of friction stir welding for large plates during welding is very troublesome, and there is no special friction stir welding positioning device for large plates in the prior art. Contents of the invention [0003] In view of the lack of a friction stir welding positioning device specifically for large plates in the prior art, the present invention provides a friction stir welding positioning device for large plates. [0004] The technical solution of the present invention to solve the technical problem is: th...
