Description

Technical Field

[0001] This utility model relates to the field of automatic clamping welding machine technology, specifically an online front and rear automatic clamping welding machine for the three-phase lead wire terminals of a new energy vehicle motor. Background Technology

[0002] Most existing welding machines are standalone machines that require manual operation. The three-phase lead wire terminal automatic clamping welding machine can automatically position and weld all three-phase wires, eliminating the cost of manual welding and improving welding accuracy and work efficiency.

[0003] A novel automatic centering resistance welding clamping machine, authorized by announcement number CN107262890B, includes a first mounting plate. A lifting cylinder is fixed on the first mounting plate. A clamping mechanism mounting plate is fixed on the piston rod of the lifting cylinder. A first slide rail is provided on the clamping cylinder mounting plate. A first slider is mounted on the first slide rail. A right clamping mechanism is fixed to the right side of the first slider. A second slide rail is fixed to the left side of the first slider. A second slider that can slide on the second slide rail is provided. A left clamping mechanism is mounted on the second slider. A clamping cylinder that drives the second slider to move on the second slide rail is fixed to one end of the second slider, so that the welding part can be clamped between the left and right clamping mechanisms. During welding, even if the welding part of the product is not between the left and right clamping mechanisms, the left and right clamping mechanisms can still achieve self-centering function when clamping the product, preventing the product from bending and reducing the occurrence of defective products.

[0004] As shown in the above equipment, existing automatic clamping welding machines can achieve self-centering even if the welding part of the product is not between the left and right clamping welding mechanisms. This prevents the product from bending and reduces the occurrence of defective products. However, when welding the three-phase lead terminals of new energy vehicle motors, precise positioning is crucial. Without a precise positioning structure, the terminals may shift during the welding process, causing the welding point to be inconsistent with the expected position. This not only affects the appearance quality of the weld but may also lead to insufficient weld strength, resulting in loosening and detachment during subsequent use, affecting the performance and safety of the motor.
