In the present invention, when it is applicable to cylinder blocks of different specifications, the positions of the fixing rods and the positioning rollers are adjusted through the adaptability adjustment mechanism to ensure a stable fixing effect, so that the push rod follows the movement of the mounting rod. When the mounting rod rotates, it can still contact the abutting block to realize the horizontal movement and cleaning effect of the positioning roller. On this basis, the left end of the abutting block is designed as an inclined structure. When the diameters of the cylinder block and the cylinder head are small, the corresponding arc of the abutting area is also small. At this time, the mounting rod rotates normally, which can adjust the reciprocating movement amplitude of the positioning roller. Therefore, when dealing with a joint with a smaller diameter, the movement frequency of the positioning roller can be increased to improve the effect of stable cleaning.

The positioning roller 10 itself can also rotate in the push ring 134 and on the mounting column 9. When the welding area is cleared, the joint can be cleaned.

[0022] Working principle: first, the cylinder body is sent into the central cavity of the fixing seat 1 by a lifting mechanism or a conveying mechanism, and the cylinder head is lifted to the end of the cylinder body by a lifting mechanism, and then the second gear 121 is driven to rotate by the built-in motor, and the second gear 121 drives the second gear ring 122 to rotate, and the guide groove 123 and the guide rod 124 drive the fixing rod 2 to move and extend in the fixing seat 1, and the cylinder body is circumferentially fixed by the end of the fixing rod 2. At the same time, the rotation of the second gear ring 122 drives the push head 125 to rotate, and the inclined surface of the push head 125 contacts the push head 125, which can push the push ring 127 to move outward, and the bottom inclined surface of the push ring 127 contacts the mounting rod 7, driving the mounting rod 7 to move inward in the movable groove 5, and then driving the mounting seat 8, the positioning roller 10 and the positioning baffle 11 to move inward, so that the positioning roller 10 is clamped at the joint between the cylinder body and the cylinder head, and the positioning baffle 11 contacts the outside of the cylinder head, so as to fix the cylinder body and the cylinder head; As welding proceeds, the first gear 3 is driven by the motor to rotate, the first gear 3 drives the first gear ring 4 to rotate, the first gear ring 4 drives the mounting rod 7 to move, and then drives the positioning roller 10 and the positioning baffle 11 to move, so that the welding area is gradually given up, and at the same time, the mounting rod 7 drives the push rod 131 to move through the second elastic telescopic rod 132, and the push rod 131 intermittently contacts with the resistance block 133, through the arc structure of the resistance block 133, in cooperation with the telescopic activity of the second elastic telescopic rod 132, the push rod 131 can drive the positioning roller 10 to move laterally on the mounting column 9 through the push ring 134, and the positioning roller 10 itself can also rotate in the push ring 134 and on the mounting column 9, when giving up the welding area, the joint can be cleaned to improve the welding effect, and at the same time, due to the inclined design of the outer end of the resistance block 133, when targeting a smaller cylinder body, the resistance block 133 reduces the stroke of the positioning roller 10, and then its reciprocating speed is accelerated, so that the mounting rod 7 can effectively avoid cleaning omissions under the same rotation speed.
