Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be described more clearly and more completely with reference to the drawings in the following embodiments, and it is understood that the described embodiments are only a part of the present invention, rather than all of the present invention, and based on the embodiments, other embodiments obtained by those skilled in the art without inventive exercise are within the protection scope of the present invention.

As shown in fig. 1 to 3, the positioner for welding comprises a frame 1 and a motor 2 mounted on the frame 1, wherein the motor 2 is connected with a rocker 3, the rocker 3 is hinged with a main swing rod 4, and a support frame 6 hinged with the main swing rod 4 and the frame 1 is arranged between the main swing rod 4 and the frame.

A movable seat 7 is welded at the front left part of the support frame 6; a displacement control box 8 is arranged on the movable seat 7, a displacement shaft 9 is arranged on the displacement control box 8 through a bearing, and the displacement shaft 9 is connected with a displacement disc 10; a displacement control component connected with a displacement shaft 9 is arranged in the displacement control box 8.

The front end of the frame 1 is provided with an arc surface 1a which is abutted with the support movable seat 7.

The displacement control assembly comprises a second motor 12 arranged in the displacement control box 8, the second motor 12 is connected with a guide rail frame 13, and a third motor 14 and a lead screw 15 are respectively arranged on the guide rail frame 13 in a fixed mode and a bearing connection mode; the third motor 14 is connected with a screw rod 15; and a movable block 16 which is slidably arranged on the guide rail bracket 13 is arranged on the screw rod 15 in a threaded manner.
