Detailed Description

The present application is described in further detail below with reference to the accompanying drawings.

The application discloses a barrel welding auxiliary machine, as shown in fig. 1, including base 1 and rotate three-jaw chuck 2 of connecting on base 1, three-jaw chuck 2 can be with work piece centre gripping and drive the work piece rotation. The motor 11 is fixed on the base 1 through bolts, and an output shaft of the motor 11 is fixed with the three-jaw chuck 2 through a coupler, so that the three-jaw chuck 2 is driven to automatically rotate, and the rotation speed of the three-jaw chuck 2 can be kept constant, so that the quality of a welding seam is not easily influenced in the welding process. Because the three-jaw chuck 2 is after holding the work piece, the one end that three-jaw chuck 2 kept away from motor 11 can receive the downward pressure that the work piece applyed to easily lead to base 1 to produce the slope, therefore the one end that base 1 kept away from three-jaw chuck 2 centre gripping work piece is provided with extension 12, extension 12 lower extreme can with ground butt, through having increased the counter weight that base 1 kept away from three-jaw chuck 2 centre gripping work piece one end, thereby make base 1 can keep stable after holding the work piece.

Since the two workpieces are connected and spot-welded between the full-welded workpieces, so that the two workpieces can be connected, two limiting pieces 13 for limiting the positions of the two workpieces are further arranged on the extension portion 12, the two limiting pieces 13 are fixed on the extension portion 12 by bolts, and a gap is reserved between the two limiting pieces 13. The limiting grooves 131 with the cross sections being isosceles triangles are formed in the upper ends of the two limiting pieces 13, the limiting grooves 131 penetrate through the side walls, close to each other, of the two limiting pieces 13, workpieces can be placed in the two limiting grooves 131 respectively, the side walls of the workpieces can be abutted to the side walls of the limiting grooves 131, the connecting positions of the two workpieces are located in gaps between the two limiting pieces 13, and therefore when the side walls of the workpieces are protruded due to spot welding, the axes of the two workpieces can still keep coincident, and accordingly the two workpieces can be kept stable in the spot welding process before full welding.

Because in the process that the workpiece is fully welded, one end of the workpiece, which is far away from the three-jaw chuck 2, is bent downwards due to the action of gravity, so that the subsequent full welding quality is affected, the supporting mechanism 3 for supporting the welded workpiece is further arranged on the base 1, the supporting mechanism 3 comprises a supporting piece 31 arranged on the base 1 and two supporting wheels 32 rotationally connected to the supporting piece 31, the axes of the two supporting wheels 32 are parallel to the axis of the motor 11, the side walls of the two supporting wheels 32 can be simultaneously abutted against the outer wall of the workpiece, and therefore one end of the workpiece, which is far away from the three-jaw chuck 2, is supported, the workpiece is not easy to deform in the full welding process, and the welding quality is not easy to be affected.

As shown in fig. 2, in order to enable the supporting mechanism 3 to support workpieces with different lengths and diameters, a sliding groove 14 parallel to the axis of the motor 11 is formed in the base 1, a screw 33 arranged vertically is fixed at the lower end of the supporting piece 31, the screw 33 is arranged in the sliding groove 14 in a penetrating manner, a lifting block 34 is connected to the screw 33 in a threaded manner, and the lower end of the lifting block 34 can be abutted to the upper end of the base 1.
