Detailed Description

Example 1: a spiral sheet welding and fixing device comprises a base 12 and a fixing rod 1; a sleeve 2 with adjustable height is arranged above the fixed rod 1, a plurality of threaded through holes are formed in the wall of the sleeve 2 along the axis, and the sleeve 2 and the C-shaped limiting ring 5 are connected through a connecting plate; still include bracing piece 6, 6 lower extremes of bracing piece are equipped with the first three and grab chuck 7, still including setting up rolling bearing 11 on base 12, 11 tops of rolling bearing are equipped with a universal joint shaft coupling 10, and universal joint shaft coupling 10 tops are equipped with the second three and grab chuck 9 and treat welded spiral piece 8 and set up in the first three and grab chuck 7 and the second three and grab between chuck 9, and bracing piece 6 is located C type spacing ring 5 and rotatable.

Further, the sleeve 2 can be followed dead lever 1 and adjusted the height from top to bottom, and sleeve 2 can be fixed by locking screw rod 3 through the screw thread through-hole cooperation of seting up on with sleeve 2, and the sleeve inner wall is attached to on dead lever 1, keeps mobilizable clearance with dead lever 1, and locking screw rod 3 cooperation screw thread through-hole when fixed, and sleeve 2 can be fixed promptly to screw in dead lever 1.

Furthermore, the C-shaped limiting ring 5 is C-shaped, and two limiting bearings 4 are respectively arranged at the opening of the C-shaped limiting ring, and the gap between the two limiting bearings 4 is smaller than the diameter of the supporting rod 6; when in use, the C-shaped limiting ring 5 mainly plays a role of being leaned against by the supporting rod 6, so that the welding is more convenient and safer; the design of the limit bearing 4 enables the support rod 6 to easily enter and exit from the C-shaped limit ring 5, and manpower is saved.

Furthermore, two ends of the universal joint coupler 10 are respectively fixed with a connecting shaft, a lower end connecting shaft is installed in a rotating bearing 11, the rotating bearing 11 is fixed on a base 12, and an upper end connecting shaft is connected with a second third grabbing chuck 9; because the screw 8 is inconvenient to vertically install when being installed into the device, the universal joint coupler 10 enables the supporting rod to be horizontally placed on the ground, and the dismounting is convenient and fast.

Further, the support rod 6 leans against the C-shaped limit ring 5 in an inclined way and can rotate and swing; the rotating bearing 11 positioned at the lower end of the universal joint coupler 10 rotates during welding, so that a welded surface is always kept in a state of being over against workers, and the welding precision and the welding efficiency are improved.

The specific using process is as follows: at the beginning: the second three-jaw chuck 9 above the universal joint coupler 10 is horizontally placed, after the second three-jaw chuck 9 clamps the inner wall of the pipe body in the screw part 8, the other end of the inner wall of the pipe body in the screw part 8 is clamped and fixed by the first three-jaw chuck 7, and when the two ends of the workpiece 8 are fixed, the sleeve, the support rod, the first three-jaw chuck and the second three-jaw chuck in the screw part form a coaxial rigid whole.

Secondly, the locking screw 3 is rotated, after the sleeve 2 is adjusted to a proper height, the locking screw 3 is rotated until the locking screw 3 clamps the sleeve 2, at the moment, the connecting plate is connected with the C-shaped limiting ring 5 and the sleeve 2, and the three are connected by welding, so that the C-shaped limiting ring 5 is also fixed, and the sleeve 2 and the C-shaped limiting ring 5 are fixed.

Then, the supporting rod 6 is supported, and the supporting rod 6 enters the C-shaped limiting ring 5 through the openings at the two ends of the C-shaped limiting ring 5 and is obliquely arranged, at the moment, the two limiting bearings 4 at the opening of the C-shaped limiting ring 5 can reduce the friction force between the supporting rod 6 and the C-shaped limiting ring 5, so that the supporting rod 6 can better enter the C-shaped limiting ring 5; because the clearance between the two limiting bearings 4 on the C-shaped limiting ring 5 is smaller than the diameter of the supporting rod 6, the supporting rod 6 in the limiting ring 5 is not easy to slide out of the C-shaped limiting ring 4, and the safety accident caused by the fact that the supporting rod 6 slides out of the C-shaped limiting ring 5 is avoided.

Then, the bearing 11 can be rotated through the supporting rod, the surface to be welded of the spiral piece is adjusted to face a worker, the worker can weld at a fixed point, and after one part to be welded is well welded, the supporting rod 6 is rotated, so that the next part to be welded faces the worker and then is welded; after the welding is finished, the supporting rod 6 is pushed to penetrate through the two limiting bearings 4 lightly and forcefully, the supporting rod 6 rotates through the universal joint coupler 10, the supporting rod is placed on the ground, the first three-jaw chuck 7 and the second three-jaw chuck 9 are sequentially loosened, the welded spiral part 8 is taken out, and the dismounting and the mounting can be finished.

The embodiment of the present invention discloses a preferred embodiment, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention according to the above embodiment, and make different extensions and changes, but do not depart from the spirit of the present invention, all of which are within the protection scope of the present invention.
