Since the pallet is used as the basis for rotation, the axial direction of the rotating shaft includes but is not limited to perpendicular to the pallet or parallel to the pallet, parallel to the structure of the pallet, The tray is provided with an I-shaped wheel fixing seat. Since the I-shaped wheel is large, the stability of the positioner is poor after clamping the I-shaped wheel. Therefore, the preferred axis of the I-shaped wheel clamping assembly is perpendicular to the supporting plate. , that is, the disk surface of the I-shaped wheel rests on the pallet.

[The first chucking plate and the second chucking plate]

In order to avoid movement interference, the clamping surface of the first chucking disc slightly protrudes from the top surface of the pallet, and the clamping surface of the second chucking disc slightly protrudes from the bottom surface of the pressing plate. The rotatable connection includes but is not limited to the interference fit between the rotating shaft of the chucking disc and the corresponding supporting plate or pressing plate, and a bearing is provided, and the chucking disc can also be connected to the corresponding supporting plate or pressing plate through a rotary member.

The rotatable connection between the pallet and the fixed seat includes, but is not limited to, a rotary oil cylinder, a motor-driven worm gear transmission mechanism, and a motor-driven gear transmission mechanism. Considering the convenience of workpiece installation and stable operation, the rotary cylinder is preferred.

[I-shaped wheel guide assembly]

The function of the I-shaped wheel guide assembly is to realize the fine adjustment of the position of the I-shaped wheel cylinder, and avoid the gap between the end of the welding torch and the weld seam caused by the deviation between the central axis of the I-shaped wheel cylinder and the central axis of rotation of the I-shaped wheel clamping assembly. The problem of inconsistent distances.

When the optimal I-wheel guide assembly is used, when the central axis of the cylinder deviates from the central axis of the I-wheel clamping assembly, the limit block moves relative to the arc surface to fit the cylinder, and the cylinder is The thrust of the limit block is adjusted slightly, the two ends of the cylinder are mated and inserted, and the disk surface is also slightly moved accordingly, and finally adjusted to the predetermined welding position.

The guiding component includes but is not limited to the above-mentioned preferred solution, and can also be a limit block on the surface of the I-shaped wheel set near the pallet or the pressure plate. By adjusting the position of the limit block on the surface of the I-shaped wheel, the position of the surface of the I-shaped wheel can be fine-tuned, and then adjusted. The position of the cylinder.

[Position bump]

The function of the positioning protrusion is: when the I-wheel clamping assembly drives the I-wheel to turn over, the clamping structure becomes more stable and reliable, and it is also to fine-tune the relative position of the disc surface at both ends of the cylinder, that is, the depression or concave hole on the disc surface relative position.

The positioning protrusion is arranged on the second clamping disc. When the concave hole on the surface of the I-shaped wheel is a through hole and the concave holes on the two disc surfaces of the I-shaped wheel are facing each other, the height of the preferred positioning protrusion is equal to or slightly less than The distance between the two disk surfaces of the I-shaped wheel.
