Background
Taking a motor of a new energy automobile as an example, a motor stator using flat wires (also called flat copper wires, namely wires with rectangular or approximately rectangular cross sections) as windings has higher copper filling rate, and can improve the power density of the motor.
The flat wire windings typically form a welded end at one axial end of the stator where the ends (also called legs) of adjacent flat wires are welded together.

In the industry, such welded end windings of flat wire having very small axial dimensions are also referred to as X-pins. The small axial dimensions of the welded ends result in a small area of the weld area, and in order to ensure weld quality, it is often necessary to use tools to clamp the weld pair.

Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific illustrations are for the purpose of illustrating how one skilled in the art may practice the invention, and are not intended to be exhaustive of all of the possible ways of practicing the invention, nor to limit the scope of the invention.
Referring to fig. 1 to 11, a winding welding tool according to a first embodiment of the present application will be described, hereinafter also simply referred to as a welding tool or tool.
Referring to fig. 1 and 2, the welding tool in the present embodiment includes a clamping device 10, a support plate 20, and a driving plate 30. The welding fixture is used for clamping the welding pair S20 of the winding end under the condition that a stator winding, particularly a stator winding of a flat wire motor, needs to be welded. Each welding pair S20 is two legs of adjacent conductors for welding together.
The support disk 20 may be stationary. The clamping device 10 is mounted on the support tray 20, and the clamping device 10 is used for clamping a plurality of welding pairs S20 to be welded according to the production tact. The driving disk 30 can rotate relative to the supporting disk 20 and drive the clamping device 10 to act.
The drive disk 30 is disposed on one side of the support disk 20 (e.g., above the support disk 20 in fig. 1), and the stator S is disposed on the other side of the support disk 20 (e.g., below the support disk 20 in fig. 1).
The clamping device 10 has a plurality of clamping positions. Fig. 3 and 4 show the support plate 20 and the drive plate 30 with the welded pair S20 of the stator clamped by the three clamping devices 10 in different positions, separately.
Specifically, referring to fig. 5, one clamping device 10 in the present embodiment includes two clamping jaws 11 and one clamping plate 12. The jaw 11 comprises a head portion 113, a first tail portion 111 and a second tail portion 112. The head 113 and the first tail 111 are directly connected and form a generally T-shaped structure. The second tail 112 is disposed at an end of the first tail 111 remote from the head 113. The head 113 is used for clamping the welding pair S20, the first tail 111 is used for cooperating with a radial rail 21 provided on the support disc 20, and the second tail 112 is used for cooperating with an arc-shaped rail 31 provided on the driving disc 30, so as to define the movement track of the clamping jaw 11.
The clamping plate 12 is formed with a clamping opening 120 penetrating in the radial direction of the stator. The head 113 of the jaw 11 extends into the grip opening 120, and the welding pair S20 also extends into the grip opening 120 (not shown in fig. 5), so that the head 113 can perform the grip positioning operation of the welding pair S20 in the grip opening 120.
Fig. 6 shows in an abstract manner a schematic view of the cooperation of the clamping device 10 and the welding pair S20 in a clamping position from above.
In this embodiment, 6 welding pairs S20 may be accommodated in each clamping opening 120, or the clamping device 10 may clamp 6 welding pairs S20 at each clamping position. The welding pairs S20 are arranged in two rows on both sides of the first tail 111 with the first tail 111 of the jaw 11 as a parting line. Each row of welding pairs forms 3 groups, located respectively radially inside the head of the first jaw, radially outside the head of the second jaw and between the heads of the two jaws.
The size of the clamping opening 120 is slightly larger than the sum of the sizes of the 3 welding pairs S20 and the two heads 113 in the radial direction of the stator, so that the insertion of the welding pairs S20 into the corresponding regions of the clamping opening 120 is easily and smoothly performed.
With the head portions 113 of the jaws 11 as dividing lines, a region between the two head portions 113 of the pair of jaws 11 is defined as a second region II, and a region of each head portion 113 on a side facing away from the second region II is defined as a first region I.
Referring to state (a) in fig. 7, the two jaws 11 are movable in a first movement such that the two jaws 11 are moved away from each other until moved to a first position, each jaw 11 cooperates with the clamping plate 12 to clamp a plurality of welding pairs S20 located at a first region I in fig. 7. Referring to state (b) in fig. 7, the two jaws 11 can also be moved in a second movement manner such that the two jaws 11 are moved close to each other until moved to the second position, clamping the plurality of welding pairs S20 located in the second region II in fig. 7 in such a manner that the two jaws 11 press against each other.
Thus, in the present embodiment, the clamping of 6 welding pairs S20 can be achieved twice at one clamping position by the two-step movement of the clamping jaw 11.
Next, with simultaneous reference to fig. 8 to 11, the specific construction of the support disc 20 and the drive disc 30, and the guidance they provide for the two modes of movement of the jaws 11, will be described.
A plurality of (3 in this embodiment) insertion holes 200 are formed in the support plate 20 concentrically around the rotation axis of the stator, and the clamping plate 12 is fixed to the support plate 20 so as to be inserted into the insertion holes 200. It will be appreciated that in other possible ways, the clamping plate 12 may also be integrally provided as part of the support disc. The advantage of the separate fabrication of the clamping plate 12 and the support disk 20 is that the clamping plate 12 can be fabricated with lower material and tooling costs, resulting in a higher dimensional accuracy of the clamping plate 12.
The thickness of the clamping plate 12 is slightly less than the thickness of the support disk 20 to allow sufficient space for the welding operation.
Also formed on the support disk 20 are a plurality of sets of radial rails 21. Each set of two radial rails 21 is intended for the first tail 111 of a pair of jaws 11 to project into, so that the jaws 11 have only a freedom of movement in the radial direction with respect to the support disc 20.
The drive disk 30 is stacked concentrically with the support disk 20. The drive disk 30 is capable of being driven by a drive source (e.g., motor, cylinder, hydraulic cylinder, etc.) to rotate about the central axis L of the support disk.
The drive disk 30 is formed with a plurality of sets (3 sets in this embodiment) of guide means, each set including an operation port 32 penetrating in the axial direction and two arcuate rails 31. Each clamping device 10 cooperates with a set of openings of the guiding device, wherein the second tail portions 112 of the two clamping jaws extend into one of the arcuate rails 31, respectively, and the clamping plate 12 is looped around the operating opening 32.
The operation opening 32 is in a substantially fan shape, and the central angle corresponding to the operation opening 32 is larger than the central angle corresponding to the clamping plate 12, so that the clamping plate 12 can be exposed out of the operation opening 32 in the process of rotating the driving disc 30, and the welding pair S20 to be welded in the clamping opening 120 of the clamping plate 12 is not blocked.
The two arc-shaped rails 31 of each set of guide means comprise an inner arc-shaped rail 311 and an outer arc-shaped rail 312, the inner arc-shaped rail 311 being located radially inward of the operation opening 32, the outer arc-shaped rail 312 being located radially outward of the operation opening 32.
Notably, the inner arcuate rail 311 and the outer arcuate rail 312 are not concentric arcs. Fig. 11 shows in a simplified abstract manner the structural features of the inner arcuate rail 311 and the outer arcuate rail 312. Defining the end of the inner arc rail 311 on one side in the circumferential direction as an inner first end M1, the end of the inner arc rail 311 on the other side in the circumferential direction as an inner second end M2, the end of the outer arc rail 312 on one side in the circumferential direction as an outer first end M3, and the end of the outer arc rail 312 on the other side in the circumferential direction as an outer second end M4, there is a case that the distance between the inner first end M1 and the central axis L is greater than the distance between the inner second end M2 and the central axis L, and the distance between the inner third end M3 and the central axis L is smaller than the distance between the inner fourth end M4 and the central axis L.
This arrangement is such that during rotation of the drive disc 30, for example, assuming that the drive disc 30 is rotated clockwise as viewed in fig. 11, the radially inner jaw 11 guided by the inner arcuate rail 311 will move radially outwardly gradually as it approaches the inner first end M1, and the radially outer jaw 11 guided by the outer arcuate rail 312 will move radially inwardly gradually as it approaches the inner third end M3.
It will be appreciated that, since the clamping jaw 11 is simultaneously guided by the radial rail 21, during the rotation of the above-described drive disc 30, the clamping jaw 11 moves relatively along the radial rail 21 with respect to the support disc 20, although the clamping jaw 11 moves relatively along the arcuate rail with respect to the drive disc 30. Therefore, when the above-described radially inner-side holding jaw moves radially outward and the radially outer-side holding jaw moves radially inward, the two holding jaws in the operation port 32 appear to be close to each other, that is, the state (b) in fig. 7.
It is to be understood that, in the present embodiment, when the drive disk 30 in fig. 11 rotates in the counterclockwise direction, the radially inner jaw moves radially inward and the radially outer jaw moves radially outward, which is shown as the two jaws in the operation port 32 are away from each other, that is, the state (a) in fig. 7.
The reader will thus appreciate that clamping of 6 welding pairs S20 can be achieved twice at one clamping position by a two-step movement of the clamping jaw 11. After each movement of the jaws causes the clamping device 10 to clamp a number of welding pairs S20, a welding device (not shown) extends to the clamping opening 120 to weld the welding pairs S20. After the two-step movement of the clamping jaw 11 and the corresponding welding are completed, i.e. after the welding of the 6 welding pairs S20 at one clamping position, the circumferential position of the whole tool relative to the stator S is adjusted, e.g. the tool is stationary, the stator S is rotated by a certain angle, after which the welding of the windings of the next circumferential region is performed.
(second embodiment)
A second embodiment of the present application is described with reference to fig. 12. The second embodiment is a modification of the first embodiment, the same reference numerals are given to the same or similar components as those in the first embodiment in terms of structure or function, and detailed description of these components is omitted.
In this embodiment, each clamping plate 12 forms 2 clamping openings 120, and each clamping opening 120 extends into 1 clamping jaw 11 and 4 welding pairs S20.
The clamping action of the clamping jaw 11 is performed in cooperation with the wall of the clamping plate 12 around the clamping opening, whether the clamping jaw is moved to a first position clamping the welding pair S20 located in the first area I or to a second position clamping the welding pair S20 located in the second area II.
It will be appreciated that since the clamping actions of the clamping jaws 11 are all completed by the wall cooperation of the clamping plates 12, the direction of movement of the two clamping jaws 11 in each step can break through the limitation of the first embodiment, i.e. the two clamping jaws 11 can be moved simultaneously radially inwards or radially outwards in addition to one radially inwards and one radially outwards. Thus, the inclination directions of the two arcuate rails in the radial direction may be different or identical.
In this embodiment, the one-step action of the pair of jaws can complete the clamping of 4 pairs of welding pairs S20, and the two-step action can complete the clamping of 8 pairs of welding pairs S20, and is particularly suitable for 8-layer flat wire windings.
(third embodiment)
A third embodiment of the present application is described with reference to fig. 13. The third embodiment is a modification of the first embodiment or the second embodiment, the same reference numerals are given to the same or similar components as those in the foregoing embodiment in terms of structure or function, and detailed description of these components is omitted.
In this embodiment, each clamping plate 12 forms 1 clamping opening 120, and 1 clamping jaw 11 and 4 welding pairs S20 extend into the clamping opening 120. This embodiment corresponds to a half structure of the second embodiment. In this embodiment, the one-step action of the pair of jaws can complete clamping of 2 pairs of welding pairs S20, and the two-step action can complete clamping of 4 pairs of welding pairs S20, and is particularly suitable for 4-layer flat wire windings.
It will be appreciated that the above-described embodiments and portions of aspects or features thereof may be suitably combined.
The present invention has at least one of the following advantages:
(i) The tool can clamp a plurality of welding pairs at a time, and has the advantages of simple structure, convenience and accuracy in control and high operation efficiency.
(ii) The clamping tool is coaxially arranged with the stator during working, and the tool is convenient and accurate to position.
(iii) At one clamping position in the circumferential direction, the clamping position can be rapidly switched by accurately moving in a short-distance positioning manner.
Of course, the present invention is not limited to the above-described embodiments, and various modifications may be made to the above-described embodiments of the present invention by those skilled in the art in light of the present teachings without departing from the scope of the present invention. For example:
(i) The movement of the clamping jaws can also be driven by other driving means, not limited to a circumferentially moving driving disk.
(ii) The specific configuration of the jaws is not limited in this application, for example, the first and second tails in the first through third embodiments are rails that extend into the channel shape, but in other possible embodiments the rails may be protrusions and the jaws may form recesses that mate with the rails.
