Welding device for hairpin motor coil

Abstract

The invention relates to a welding device for a hairpin motor coil. The welding device comprises a frame body, a welding mechanism and a clamp. The welding mechanism comprises a support and a welding piece, wherein the support is further connected with a welding driving piece driving the welding piece to move, and the driving end of the welding driving mechanism is connected with the welding piece. The clamp comprises a base, a material ejecting sleeve, a plurality of inner pressing blocks and a plurality of outer pressing blocks, wherein a mandrel sleeve is arranged in the material ejecting sleeve and connected with the base, the inner pressing blocks are connected to the upper end face of the mandrel sleeve in a circumferential sliding mode, the mandrel sleeve is connected with a first driving mechanism, the outer pressing blocks slide at the upper end of the base in the circumferential direction, and the end faces of the inner pressing blocks and the outer pressing blocks abut against the side wall of a flat wire set. The position of a wire end is limited through the outer pressing blocks and the inner pressing blocks, then the wire end is welded through the welding piece, and at the moment, the position of the wire end is limited in the welding process, and therefore, the welding quality of the wire end is higher, so that the quality of a machined stator is higher.

Description

Technical field [0001] The present application relates to the field of cardboard motor processing equipment, and more particularly to a welding device for a card motor coil. Background technique [0002] The cardboard motor is also called a flat line motor, which has a small size, high power, high torque. The stator of the card motor needs to be positioned and tightened in the production process, and then the welder is used. Welding the flat line group. [0003] Currently, many manufacturers are still in the state of manual clutch, which manually locks the stator in manual clamps when welding, and then manually adjusting the pressure block to make the same flat line group The thread is close to and positioned, and then welded. [0004] In response to the above-described related art, the inventors believe that when positioning the wire header of the flat line group, it is difficult to ensure that the position of each thread is moved to the required position, resulting in the final...
