Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, and in particular to a segmented stator core welding device. Background Technology

[0002] Axial flux motors are a new type of motor that offers significant advantages over traditional radial flux motors: smaller size, lighter weight, higher power and torque density, higher efficiency, and lower noise and vibration. They are ideal for applications with stringent noise and vibration requirements, such as EPS and EMB motors in automotive chassis. Especially in EMB motor applications requiring fast response and short axial length, the lighter rotor and lower moment of inertia of axial flux motors allow for rapid command response and millisecond-level action switching, resulting in high control precision. This makes them suitable for applications demanding high-speed motion and precise control. However, the stator core of axial flux motors is typically formed using rolling, punching, and riveting, leading to higher equipment costs.

[0003] The stator core of the existing axial flux motor adopts a modular structure, which is made by welding multiple segmented stator cores. During the welding process, a clamp is usually used to splice the segmented stator cores. However, the spliced ​​segmented stator cores are unstable, which makes it easy for deviations to occur during the welding process. Utility Model Content

[0004] The purpose of this utility model is to provide a segmented stator core welding device, which solves the problem that the segmented stator core is usually spliced ​​by a clamp during the welding process, but the spliced ​​segmented stator core is unstable, which leads to deviations during the welding process.

[0005] To achieve the above objectives, this utility model provides a segmented stator core welding device, including a base and a fixing plate, the fixing plate being fixedly installed on the base. It also includes a splicing device, which comprises a mounting base, a fixing block, a first clamping plate, a second clamping plate, a guide rod, and a pushing assembly. The mounting base is fixedly installed on the fixing plate and has a slot. The fixing block is fixedly installed on the base and close to the fixing plate. The guide rod is fixedly installed on the fixing block. Both the first and second clamping plates are slidably engaged with the guide rod, and are located on opposite sides of the mounting base. The pushing assembly is installed on the guide rod.

[0006] The propulsion assembly includes a first propulsion ring and a second propulsion ring. The first propulsion ring is threadedly engaged with the guide rod and is located near the first clamping plate. The second propulsion ring is threadedly connected to the guide rod and is located near the second clamping plate.

[0007] The propulsion assembly further includes a rotating component, which comprises a first rotating rod and a second rotating rod. The first rotating rod is fixedly mounted on the first propulsion ring, and the second rotating rod is fixedly mounted on the second propulsion ring.

[0008] The splicing device further includes a reset assembly, which includes a first reset spring and a second reset spring. The two ends of the first reset spring are fixedly connected to the first clamping plate and the fixing block, respectively; the second reset spring is fixedly connected to the second clamping plate and the fixing block, respectively.

[0009] This utility model discloses a segmented stator core welding device. In use, segmented stator cores are placed sequentially into the slots on the mounting base, assembling them into a complete circular stator core. Then, by rotating the first rotating rod, the first pushing ring is rotated, causing it to slide along the guide rod towards one side of the mounting base through its threaded engagement with the guide rod. This causes the first clamping plate to press the segmented stator cores together, and similarly, the second clamping plate presses the segmented stator cores together, ensuring that the segmented stator cores are firmly attached to the mounting base. This prevents the segmented stator cores from loosening during welding with an external welding gun, thus guaranteeing the welding effect. Attached Figure Description

Detailed Implementation

[0014] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0015] The embodiment of this application is as follows: Please see Figure 1-2 , Figure 1 This is a schematic diagram of the overall structure of a segmented stator core welding device according to this utility model. Figure 2 This is a schematic diagram of the card holder structure of this utility model.

[0016] This utility model provides a segmented stator core welding device, including a base 101 and a fixing plate 102, and a splicing device. The splicing device includes a card holder 103, a fixing block 104, a first clamping plate 105, a second clamping plate 106, a guide rod 107, and a pushing assembly. The pushing assembly includes a first pushing ring 109 and a second pushing ring 110. The pushing assembly also includes a rotating component, which includes a first rotating rod 111 and a second rotating rod 112. The splicing device also includes a reset assembly, which includes a first reset spring 113 and a second reset spring 114. The aforementioned solution solves the problem that in the welding process of segmented stator cores, card holders are usually used to splice the segmented stator cores, but the spliced ​​segmented stator cores are unstable, which easily leads to deviations during the welding process.

[0017] In this embodiment, the clamping plate 105 and the clamping plate 106 firmly secure the segmented stator core to the mounting base 103, ensuring that the segmented stator core will not loosen when welded by an external welding gun, thus guaranteeing the welding effect.

[0018] The card holder 103 is fixedly mounted on the fixed disk 102. The card holder 103 has slots 108. The fixing block 104 is fixedly mounted on the base 101, close to the fixed disk 102. The guide rod 107 is fixedly mounted on the fixing block 104. The first clamping plate 105 and the second clamping plate 106 are slidably engaged with the guide rod 107. The first clamping plate 105 and the second clamping plate 106 are located on opposite sides of the card holder 103. The pushing assembly is mounted on the guide rod 107. The card holder 103 is welded to the fixed disk 102. The card holder 103 has a circular structure. Multiple sets of slots 108 are arranged in a ring on the card holder 103. The fixing block 104 is welded... On both sides of the base 101, the first clamping plate 105 and the second clamping plate 106 are both arc structures, and both sides of the first clamping plate 105 and the second clamping plate 106 are provided with round holes. The guide rod 107 is welded between the fixing blocks 104 on both sides. The segmented stator core is clamped by the slot 108 on the card seat 103, so that the segmented stator core is assembled into a complete stator core. The push assembly pushes the first clamping plate 105 and the second clamping plate 106 towards each other along the guide rod 107, so that the first clamping plate 105 and the second clamping plate 106 firmly hold the segmented stator core on the card seat 103, so that the segmented stator core will not loosen when welded by an external welding gun, thus ensuring the welding effect.

[0019] Secondly, the first push ring 109 is threadedly engaged with the guide rod 107, and the first push ring 109 is close to the clamping plate 105; the second push ring 110 is threadedly connected to the guide rod 107, and the second push ring 110 is close to the clamping plate 106. Both the first push ring 109 and the second push ring 110 are threaded inside. By rotating the first push ring 109 and the second push ring 110, the first push ring 109 and the second push ring 110 move on the guide rod 107 and push the clamping plate 105 and the clamping plate 106 respectively.

[0020] Secondly, the first rotating rod 111 is fixedly installed on the first propulsion ring 109; the second rotating rod 112 is fixedly installed on the second propulsion ring 110. The first rotating rod 111 is circumferentially welded to the first propulsion ring 109, and the second rotating rod 112 is circumferentially welded to the second propulsion ring 110. The arrangement of the first rotating ring and the second rotating ring facilitates the rotation of the first propulsion ring 109 and the second propulsion ring 110.

[0021] Furthermore, the two ends of the first reset spring 113 are fixedly connected to the first clamping plate 105 and the fixing block 104, respectively; the second reset spring 114 is fixedly connected to the second clamping plate 106 and the fixing block 104, respectively. The axes of the first reset spring 113 and the second reset spring 114 coincide. The arrangement of the first reset spring 113 and the second reset spring 114 facilitates the reset of the first clamping plate 105 and the second clamping plate 106.

[0022] In this embodiment, during use, the segmented stator cores are sequentially placed in the slots 108 on the mounting base 103, so that the segmented stator cores are assembled into a complete circular stator core. Then, by rotating the first rotating rod 111, the first pushing ring 109 is driven to rotate, so that the first pushing ring 109 slides along the guide rod 107 towards one side of the mounting base 103 through the threaded engagement with the guide rod 107, and drives the clamping plate 105 to press the segmented stator cores tightly. Similarly, the clamping plate 106 presses the segmented stator cores tightly, so that the segmented stator cores are firmly on the mounting base 103, so that the segmented stator cores will not loosen when welded by an external welding gun, thus ensuring the welding effect.

[0023] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
