WELDING POSITIONING APPARATUS
The present application relates to a welding positioning apparatus, wherein a press head may be capable of pressing a first component against the second component, and dust generated during welding may be allowed to be collected in a dust collection chamber, and discharged to the outside of the welding positioning apparatus by an external dust extractor to keep the welding environment clean, thereby improving the welding quality.
1 . A welding positioning apparatus for positioning a first component and a second component to be welded, the welding positioning apparatus comprising:
a main body penetratingly provided with a welding operation inlet; and
a press head comprising a connecting end and a positioning end arranged opposite each other, the connecting end being detachably assembled to one side of the main body and communicating with the welding operation inlet, and the positioning end pressing the first component against the second component and being provided with a welding operation outlet communicating with a position to be welded;
wherein a part of an inner cavity of the press head is constructed to form a welding channel defined with the welding operation inlet and the welding operation outlet, and the other part is constructed as a dust collection chamber communicating with the welding channel; and
the press head is penetratingly provided with at least one dust removal port communicating with the dust collection chamber, and the dust removal port is used to transfer dust collected in the dust collection chamber during welding.
2 . The welding positioning apparatus according to claim 1 , wherein the welding positioning apparatus comprises an elastic structure, the elastic structure being deformably connected between the main body and the press head in a pressing direction of the press head.
3 . The welding positioning apparatus according to claim 1 , wherein the welding positioning apparatus comprises a bottom plate and at least one dust suction pipe, the bottom plate is penetratingly provided with a welding groove, the main body is detachably assembled to one side of the bottom plate, the welding operation inlet is opposite and communicates with the welding groove, and each of the dust suction pipes is jointed and communicates with each of the dust removal ports.
4 . The welding positioning apparatus according to claim 3 , wherein two dust suction pipes are provided, one of the dust suction pipes is fitted to one side of the press head in a direction intersecting the welding channel and communicates with the dust collection chamber, and the other of the dust suction pipes is fitted to the main body in a direction parallel to the welding channel and communicates with the dust collection chamber.
5 . The welding positioning apparatus according to claim 3 , wherein the welding positioning apparatus further comprises a position-limit structure disposed on the bottom plate, the position-limit structure being connected between the bottom plate and the main body to restrict the main body to the bottom plate.
6 . The welding positioning apparatus according to claim 5 , wherein the position-limit structure is constructed as a first positioning pin protruding from the bottom plate, and a first groove matching the first positioning pin is disposed on a surface of the main body facing toward the bottom plate.
7 . The welding positioning apparatus according to claim 1 , wherein the welding positioning apparatus further comprises a first movable structure and a second movable structure respectively disposed on two sides of the main body in a preset direction, and a mounting position with an adjustable spacing in the preset direction is defined between the first movable structure and the second movable structure to mount the main body.
8 . The welding positioning apparatus according to claim 7 , wherein the first movable structure and the second movable structure are both constructed as movable cylinders.
9 . The welding positioning apparatus according to claim 7 , wherein a second positioning pin protrudes from a surface of the first movable structure facing toward the main body, and a second groove matching the second positioning pin is disposed on a surface of the main body facing toward the first movable structure;
and/or a third positioning pin protrudes from a surface of the second movable structure facing toward the main body, and a third groove matching the third positioning pin is disposed on a surface of the main body facing toward the second movable structure.
10 . The welding positioning apparatus according to claim 3 , wherein the first component is constructed as a top cover of a battery cell, the second component is constructed as two connector pieces, welded to the top cover, in the battery cell, and two press heads are provided, the two press heads being respectively used to position the two connector pieces onto the top cover;
Wherein the two press heads are assembled to both ends of the main body in a length direction of the top cover.
11 . The welding positioning apparatus according to claim 10 , wherein the welding positioning apparatus further comprises two movable cylinders disposed on the bottom plate, the two movable cylinders being mounted on the bottom plate in a width direction of the top cover and clamping or releasing the main body in the width direction of the top cover.
12 . The welding positioning apparatus according to claim 10 , wherein two dust suction pipes are provided, the two dust suction pipes being mounted at opposite ends of the bottom plate in the width direction of the top cover and used to limit the main body in the length of the top cover.
