WELDING APPARATUS AND WELDING DEVICE
A welding apparatus includes a body portion, a welding part disposed on the body portion and configured to weld welding points on a to-be-welded object, and a distance measuring part disposed on the body portion and located on a side of the body portion that faces the welding part. The distance measuring part is configured to measure defocus amounts from the welding points on the to-be-welded object to the welding part. The welding part and the distance measuring part are aligned to different ones of the welding points at a same time, so that the welding part and the distance measuring part simultaneously perform welding and distance measurement on the different ones of the welding points.
1 . A welding apparatus, comprising:
a body portion;

a distance measuring part, disposed on the body portion and located on a side of the body portion that faces the welding part, and configured to measure defocus amounts from the welding points on the to-be-welded object to the welding part;
wherein the welding part and the distance measuring part are aligned to different ones of the welding points at a same time, so that the welding part and the distance measuring part simultaneously perform welding and distance measurement on the different ones of the welding points.
2 . The welding apparatus according to claim 1 , wherein:
the distance measuring part comprises multiple distance meters, wherein the multiple distance meters are configured to simultaneously perform distance measurement on multiple welding points on the to-be-welded object; and
the welding part is configured to perform welding on the multiple welding points that have been measured by the multiple distance meters.
3 . The welding apparatus according to claim 2 , wherein the distance measuring part further comprises a position adjustment component, and the multiple distance meters are all disposed on the position adjustment component.
4 . The welding apparatus according to claim 3 , wherein the position adjustment component comprises a first slide rail and a second slide rail that are disposed perpendicular to each other, wherein the first slide rail is fastened on the body portion, the second slide rail is slidably disposed on the first slide rail, and the distance meters are slidably disposed on the second slide rail.
5 . The welding apparatus according to claim 1 , wherein a positioning part is disposed on the body portion.
6 . The welding apparatus according to claim 1 , wherein a blowing part is disposed on the body portion.
7 . The welding apparatus according to claim 1 , further comprising:
an inspection part, wherein the inspection part is configured to inspect and calibrate the distance measuring part.
8 . The welding apparatus according to claim 7 , wherein a step-like structure is disposed on the inspection part.
9 . The welding apparatus according to claim 8 , wherein positioning through holes are provided at corners of the inspection part.
10 . The welding apparatus according to claim 9 , wherein the inspection part is further provided with blind holes.
11 . The welding apparatus according to claim 10 , wherein:
the inspection part is rectangular;
the positioning through holes comprise a first through hole, a second through hole, a third through hole, and a fourth through hole; and
the blind holes comprise a first blind hole closest to the first through hole with a distance of l a , a second blind hole closest to the second through hole with a distance of l b , a third blind hole closest to the third through hole with a distance of l c , and a fourth blind hole closest to the fourth through hole with a distance of l d ; and
