Background

Due to the welding requirement of the square conductor stator, a welding tool is needed to assist welding. The structure of the square conductor stator is shown in fig. 1-2, a plurality of copper wires 33 are arranged on the end surface 34 of the stator core of the square conductor stator 3, the upper ends of the copper wires 33 are stripped with paint coats 32 to form paint coat stripping joints 31, and a gap Z before clamping is arranged between two adjacent paint coat stripping joints 31. The clamping of square conductor stator can not be satisfied to conventional welding frock.

Therefore, a square conductor stator flat wire welding tool capable of being clamped quickly needs to be designed, so that laser welding of the square conductor stator is facilitated.

Disclosure of Invention

The utility model aims at overcoming the not enough of prior art, provide a square conductor stator flat wire welding frock that can quick clamping to the laser welding of square conductor stator.

In order to achieve the purpose, the utility model relates to a square conductor stator flat wire welding frock, including frock body, location base, its characterized in that: the tool body comprises a guide ring, a tool stop screw, a tool plate and a square conductor lead-in hole, the guide ring is arranged in the center of the tool plate, the square conductor lead-in holes are formed in the surface of the tool plate and located on the periphery of the guide ring, and the tool stop screw is arranged on the circumference of the tool plate.

The lower end of the square conductor stator is inserted into the positioning base, and the paint removing connector of the square conductor stator is inserted into the square conductor lead-in hole.

The circumference of the tooling plate is also provided with a tooling taking-out screw.

Handles are arranged on two sides of the tooling plate.

And an outward-inclined chamfer structure is arranged at the guide inlet at the lower end of the square conductor guide hole.

Compared with the prior art, the utility model, can press from both sides tight a large amount of copper lines simultaneously and remove the enamel skin joint, realize that quick multiple spot presss from both sides tightly, press from both sides tightly efficiently. The welding slag splashing prevention structure enables the welding tool to be easy to clean and maintain. The clamping position is adjustable, and the tool is convenient to take out after welding. The utility model has the advantages of simple structure, low cost and simple operation.

Detailed Description

The invention will now be further described with reference to the accompanying drawings.

Referring to fig. 3-5 and 7, the utility model relates to a square conductor stator flat wire welding frock, including frock body, location base, frock body 1 includes guide ring 11, frock end position screw 12, frock board 14, square conductor inlet hole 16, and the central authorities of frock board 14 are equipped with guide ring 11, and a plurality of square conductor inlet hole 16 sets up on the surface of frock board 14 to be located the periphery of guide ring 11, be equipped with frock end position screw 12 on the circumference of frock board 14.

The utility model discloses at the during operation, at first place square conductor stator 3 on location base 2, the location is accomplished in square conductor stator 3's lower extreme inserts location base 2. Then manual removal frock body 1 is to the positive upper end of 3 copper lines 33 of square conductor stator, the hole of the square conductor stator 3 is aimed at to the guide ring 11 that has the tapering, down insert until 14 lower surfaces of frock board touch and remove the enamel and connect 31, manual frock body 1 is until all the enamel and connect 31 and aim at the square conductor inlet hole 16 on the frock body 1, the reuse power is down pressed, stop a screw 12 and touch stator core terminal surface 34 until the frock, the enamel and connect 31 of going of square conductor stator 3 inserts in the square conductor inlet hole 16, frock body 1 presss from both sides tight all copper line pairwise joints.

The utility model discloses, for the convenience of manual control frock board 14, frock board 14's both sides are equipped with handle 15.

Referring to fig. 8 to 11, the lower end lead-in opening of the square conductor lead-in hole 16 is provided with an outward-inclined chamfer structure 161, the width D of the lead-in opening is larger than the width D2 before clamping the square conductor, and the lead-in opening is provided with the outward-inclined chamfer structure 161, so that the stripper rubber 31 can enter into the square conductor lead-in hole 16 of the tool body 1. Because the width D1 of the clamping opening is smaller than the width D2 of the square conductor before clamping and is equal to the sum of the widths of the two copper wires, the two copper wires are gradually drawn together and clamped in the process of passing through the chamfering structure 161 until the tool stop screw 12 touches the end face 34 of the stator core, and the depth of the gap Z before clamping is reduced to zero at one part of the top end of the two adjacent depainting joints 31, so that the process requirement of laser welding is met. After being clamped in place, as shown in fig. 6, laser is used for welding at a set position 4, and after welding, copper wire materials are melted in a melting area 5 to form a welding head 6. Because the welding position is in the central area of the copper wire clamping position and far away from the four walls of the square conductor lead-in hole 16, the heating temperature of the tool is far lower than that of the copper wire center, and the tool plate 14 and the copper wire are made of different materials, the two materials cannot be fused together.

Because during welding, the motor stator winding below the tooling plate 14 is completely isolated by the tooling plate 14, welding slag can not splash and fall in the stator winding area in the welding process. After welding is completed, if the tool body 1 cannot be pulled out manually, the tool taking-out screw 13 on the circumference of the tool plate 14 can be screwed, and the tool body 1 is ejected out by utilizing the jacking force generated by the tool taking-out screw 13.
