Description

Technical Field

[0001] This disclosure relates to the technical field of welding equipment, and in particular to a resistance welding apparatus. Background Technology

[0002] Resistance welding equipment is an industrial device that uses the resistance heat generated by the current passing through the workpiece and the contact area as a heat source to locally heat the workpiece while simultaneously applying pressure to weld it. Resistance welding equipment is widely used in automobile manufacturing, electronic equipment manufacturing, home appliance manufacturing, metal processing, medical devices, and aerospace industries.

[0003] The resistance welding apparatus of the related technology includes a worktable, a clamping and positioning mechanism, and a lifting mechanism. The clamping and positioning mechanism and the lifting mechanism are both connected to the worktable. The lifting mechanism is provided with an upper electrode part, which drives the upper electrode part to move up and down in the vertical direction. The upper electrode part is used to place the part to be welded. The clamping and positioning mechanism is used to fix the mother body to be welded. The clamping and positioning mechanism is provided with a lower electrode part. The upper electrode part and the lower electrode part abut against each other to resist welding the part to be welded to the mother body, such as Chinese Patent No. CN201520632656.5.

[0004] However, since the lifting mechanism drives the upper electrode to move up and down in the vertical direction, and the upper electrode is used to place the part to be welded, the upper electrode drives the part to be welded to move up and down in the vertical direction. This means that the resistance welding device can only drive the part to be welded to move up and down in the vertical direction, which makes the adjustment flexibility of the processing position of the part to be welded during resistance welding poor.

[0019] In one embodiment, a fixed plate is provided at the connection between the vertical adjustment drive and the horizontal adjustment seat. The fixed plate has a clearance hole, and the power output end of the vertical adjustment drive passes through the clearance hole and connects to the vertical adjustment seat.

[0020] In one embodiment, the vertical adjustment seat has a vertical sliding groove, and the side of the horizontal adjustment seat opposite to the horizontal connecting seat has a vertical sliding part, which passes through the vertical sliding groove and is slidably connected to the vertical adjustment seat.

When the storage body is located directly below the upper electrode, the upper electrode is used to clamp the sub-component to be welded stored in the storage cavity.

[0023] Compared with the prior art, this disclosure has at least the following advantages:

[0024] 1. The upper electrode is used to clamp the part to be welded, and the vertical adjustment mechanism is used to drive the upper electrode to move along a third direction, so that the upper electrode can drive the part to be welded to move along a third direction; the horizontal adjustment mechanism is used to drive the vertical adjustment mechanism to move along a second direction, so that the vertical adjustment mechanism and the upper electrode work together to drive the part to be welded to move along a second direction; the longitudinal adjustment mechanism is used to drive the horizontal adjustment mechanism to move along a first direction, so that the horizontal adjustment mechanism, the vertical adjustment mechanism and the upper electrode work together to drive the part to be welded to move along a first direction, so that the part to be welded moves to a predetermined position along the first direction, the second direction and the third direction respectively under the action of the resistance welding device, so that the part to be welded is resistance welded to the predetermined position of the mother body, and the resistance welding process is completed.
