DETAILED DESCRIPTION

[0015] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0016] See also Figure 1-3, an embodiment of the present invention: a friction stir welding machine, comprising a base 1, a support frame 2 arranged on one side of the base 1; a welding unit 3 is arranged on the support frame 2, and the welding unit 3 is connected to the support frame 2 through a connecting plate 30; a screw rod 35 is also arranged on the connecting plate 30, and the screw rod 35 is connected to a driving member 31 provided on the connecting plate 30; the screw rod 35 is connected to a mounting frame 34 provided, and a chassis 32 is provided on the mounting frame 34, and a spindle head 33 is also provided on the chassis 32; a slide rail 6 is also provided on the base 1, and a station adjustment component 5 is slidably installed on the slide rail 6; the station adjustment component 5 includes a base 50, a rotating table 57 is rotatably installed on the base 50, a reduction motor 53 is provided on the side of the rotating table 57 facing the base 50, and the output end of the reduction motor 53 is connected to a supporting platform 56 provided.

[0017] In summary, since the station adjustment component 5 can slide on the base 1, the position adjustment component 5 can be adjusted on the horizontal plane, the rotating table 57 can rotate on the base 50, that is, the rotating table 57 can swing on the base 50, so that the angle of the workpiece during welding can be adjusted, and the bearing table 56 can rotate on the rotating table 57 under the action of the reduction motor 53. Based on this, the workpiece placed on the bearing table 56 can be adjusted at multiple angles to meet the welding requirements of special-shaped workpieces.

[0018] Furthermore, since the base 50 is provided with a driving wheel 52 , and the driving wheel 52 is meshed with a gear wheel 54 provided on the side of the rotating platform 57 , the rotating platform 57 can be driven to rotate by the driving wheel 52 .

[0019] At the same time, since the base 50 is also provided with a locking member 51, and one end of the locking member 51 passes through the base 50 and is connected to the arc groove 55 provided on the side of the rotating platform 57, the rotating platform 57 can be positioned when the locking member 51 is locked, and vice versa, the rotating platform 57 is released to swing on the base 50 after the locking member 51 is loosened. The locking member 51 is a screw rod that passes through the arc groove 55 and is connected to a nut to lock or release the rotating platform 57.

[0020] Furthermore, an angle value is also provided on the outer side surface of the arc groove 55 , so that the rotation angle of the rotating platform 57 can be precisely controlled by reading the angle value data.

[0021] Furthermore, since the base 1 is also provided with a driving rod 4, and the driving rod 4 rotates to make the station adjustment component 5 slide on the base 1, the station adjustment component 5 is easy and convenient to move on the base 1.

[0022] In addition, since the support platform 56 is in a disc shape, the support platform 56 will not be blocked by the support frame 2 when rotating.

[0023] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
