Description

Technical Field

[0001] This utility model belongs to the field of Xpin stator welding, specifically, it relates to a clamping fixture for welding copper wires at the end of Xpin. Background Technology

[0002] The stator core is an important component of the motor's magnetic circuit. Together with the rotor core and the air gap between the stator and rotor, it forms the complete magnetic circuit of the motor.

[0003] Chinese Patent Application No. 202422303594.5 discloses an ultra-low welding clamping fixture for iron core copper wire, including a tray. A radial clamping fixture is mounted on the tray above the iron core. A circumferential clamping fixture is mounted on the upper side of the radial clamping fixture. The radial clamping fixture includes a fixed support plate, a rotating drive plate rotatably connected to the lower side of the fixed support plate, and a support guide plate mounted on the lower side of the fixed support plate. The upper side of the support guide plate has multiple radial grooves arranged in a circular array. Radial guard blocks are slidably connected within the radial grooves. Multiple reference grooves are formed through the support guide plate and the radial guard blocks. Multiple arc-shaped grooves are formed through the rotating drive plate. A follower column that can slide within the arc-shaped groove is mounted on the lower side of the radial guard block. A locking assembly that drives the rotating drive plate to rotate is mounted on the lower side of the fixed support plate. This invention has the advantage of radially limiting the copper wire at the end of the iron core, preventing damage to the bent portion of the copper wire.

[0004] The above technical solution has the following drawbacks:

[0005] Because the vertical section of the copper wire at the end of the Xpin stator is very short, the traditional method of clamping the end of the copper wire from the left and right is not only difficult to clamp, but also seriously damages the copper wire coating. Therefore, a tooling that can firmly clamp the copper wire at the end of the Xpin stator is designed to ensure the smooth progress of the welding work. Utility Model Content

[0006] To address the above deficiencies, this utility model provides a clamping fixture for welding copper wire at the Xpin end, including an assembly plate. Gear reducers are mounted on the upper and lower ends of the left and right sides of the assembly plate, respectively. The output ends of both gear reducers penetrate the assembly plate and are connected to gears. A through hole for mounting clamping components is provided in the middle of the assembly plate. The clamping components, from top to bottom, consist of a clamping tooth cover plate, a first clamping tooth rotating disk, a clamping tooth guide disk, a second clamping tooth rotating disk, and a clamping tooth base plate, and are fixed together by bolts.

[0007] The upper and lower ends of the outer edges of the two toothed rotating disks are respectively equipped with racks that mesh with the gears on both sides;

[0008] The toothed guide plate confines the two toothed rotating disks to their upper and lower sides for rotation.

[0009] The guide disc with clamping teeth is also provided with several clamping groups for clamping copper wires.

[0010] Furthermore, a set of symmetrical arc-shaped baffles is fixed on both the upper and lower surfaces of the toothed guide disc, and the two toothed rotating discs are respectively limited by the two sets of arc-shaped baffles.

[0011] Furthermore, the toothed guide disc has several arc-shaped grooves arranged in a circular array, and each arc-shaped groove is connected to the clamping assembly through an installed cam follower.

[0012] Furthermore, the clamping assembly includes an upper clamping tooth and a lower clamping tooth that are fixed after passing through a cam follower, and the clamping ends of the upper clamping tooth and the lower clamping tooth are adapted to each other.

[0013] Furthermore, a matching stop block is fixed between the clamping ends of the upper and lower clamping teeth respectively. The copper wire is clamped after the stop blocks at the upper and lower clamping teeth abut against each other, and the contact surface of the stop block is also provided with a protrusion.

[0014] Furthermore, two symmetrically arranged handles are installed on the upper surface of the toothed guide disc.

[0015] Furthermore, the upper surface of the assembly plate is also hinged with several limiting buckles for limiting the position of the clamping components via pins.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This invention uses multiple pairs of copper wires in the same radial direction as the center, with one copper wire in each pair as the reference, and adopts a synchronous clamping method from front to back. This improves the wire clamping error tolerance, and while clamping the copper wires, it also straightens the copper wires, making the copper wires neat and the clamping effect better, thus ensuring the welding quality of the subsequent copper wires.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example

[0029] like Figures 1 to 8 As shown, this embodiment provides a clamping fixture for welding copper wire at the Xpin end, including an assembly plate 7. The upper and lower ends of the left and right sides of the assembly plate 7 are respectively equipped with a reduction motor 8. The output ends of the two reduction motors 8 pass through the assembly plate 7 and are connected to gears 2, thereby driving the meshing rack 31 to achieve the overall rotation of the clamping assembly.

[0030] In detail, the assembly plate 7 has a through hole in the middle for installing the clamping components. The clamping components are arranged from top to bottom as follows: clamping tooth cover plate 1, first clamping tooth rotating disk 3, clamping tooth guide disk 5, second clamping tooth rotating disk 3, and clamping tooth base plate 4. The clamping tooth guide disk 5 is fixed to the assembly plate 7 by bolts. The two clamping tooth rotating disks 3 are rotatably connected to the upper and lower ends of the clamping tooth guide disk 5, respectively. Two symmetrically arranged handles 9 are installed on the upper surface of the clamping tooth guide disk 5 to facilitate the disassembly of the entire clamping components. The upper surface of the assembly plate 7 is also hinged with several limit buckles 10 for limiting the outer edge of the upper surface of the clamping tooth guide disk 5 by pins to ensure the overall stability of the clamping components.

[0031] The upper and lower ends of the outer edges of the two toothed rotating disks 3 are respectively equipped with racks 31 that mesh with the gears 2 on both sides. It should be noted that since the outermost edge of the rack 31 is located outside the outer ring of the toothed rotating disk 3, the inner wall of the through hole should also be provided with an extension groove corresponding to the shape of the two racks 31, so that the racks 31 can pass through when disassembling and assembling the clamping assembly.

[0032] A set of symmetrical arc-shaped baffles 53 are fixed on both the upper and lower surfaces of the toothed guide plate 5. The toothed cover plate 1 and the toothed base plate 4 are respectively fixed to the adjacent arc-shaped baffles 53 by bolts. After the two toothed rotating discs 3 are confined inside by the two sets of arc-shaped baffles 53, they rotate inside them (that is, one toothed rotating disc 3 is located between the toothed cover plate 1 and the toothed guide plate 5, and the other toothed rotating disc 3 is located between the toothed base plate 4 and the toothed guide plate 5). The toothed guide plate 5 is also provided with several clamping groups for clamping copper wires 6. The clamping groups are slidably arranged in several toothed grooves 52 arranged in a circular array around the center of the toothed guide plate 5. Specifically, the clamping group includes an upper tooth 3. The clamping ends of the upper clamping tooth 33 and the lower clamping tooth 34 are adapted to each other, and a cam follower 32 is installed at the ends of the upper clamping tooth 33 and the lower clamping tooth 34 that are far apart from each other. A matching stop block 35 is fixed between the clamping ends of the upper clamping tooth 33 and the lower clamping tooth 34 respectively. The stop block 35 is set according to the actual number of layers of copper wire 6 at the stator end, so that the upper clamping tooth 33 and the lower clamping tooth 34 can be completely fitted on the stator end to achieve synchronous clamping of all copper wire pairs. After the stop block 35 at the upper clamping tooth 33 and the lower clamping tooth 34 abuts, the copper wire 6 is clamped. The contact surface of the stop block 35 is also provided with a protrusion 36. The upper clamping tooth 33 and the lower clamping tooth 34 move towards each other when clamping the wire to achieve the purpose of clamping the wire.

[0033] Both toothed rotating disks 3 are provided with several arc-shaped sliding grooves 37 arranged in a ring array. Each pair of upper and lower corresponding arc-shaped sliding grooves 37 are used to slide and limit the cam follower 32 located at the toothed sliding groove 52 on the same vertical line.

[0034] It should be noted that the number of cam followers 32 is the same as the number of clamping groups. Multiple cam followers 32 can be set in each arc-shaped slide groove 37. Depending on the actual stator specifications, the number of clamping groups can be changed to achieve the purpose of clamping wire and improve compatibility. This will not be elaborated here, but can be increased or decreased according to actual needs.

[0035] The Xpin end welding copper wire clamping fixture described in this embodiment is used to clamp the copper wire 6 at the stator end. Two reduction motors 8 drive gears 2, which in turn drive the clamping tooth rotating disk 3 to rotate synchronously through meshing racks 31. During the rotation of the two clamping tooth rotating disks 3, the cam follower 32 on the upper clamping tooth 33 and the lower clamping tooth 34 moves along the arc-shaped slide groove 37. During this process, the ends of the upper clamping tooth 33 and the lower clamping tooth 34 move towards each other, and the protrusion 36 presses the copper wire 6, so that the copper wire 6 can be as close as possible to cooperate with subsequent welding, thereby achieving the purpose of clamping the copper wire 6.

[0036] Furthermore, the front and rear ends of each copper wire 6 are clamped simultaneously, and the clamping process can shape the ends to a certain extent (the ends of the copper wire 6 have irregularities).

[0037] It should be noted that before the upper clamping tooth 33 and the lower clamping tooth 34 are fitted onto the stator end, the ends of the two must be aligned vertically, and the width of the reserved grooves on both sides of the clamping tooth cover plate 1 and the clamping tooth base plate 4 should be greater than the width of the rack 31.

[0038] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
