Description

Technical Field

[0001] The invention relates to the technical field of motor manufacturing, and in particular to an auxiliary tooling for inserting a coil of a motor stator. Background Art

[0002] The process of inserting coils into the motor stator, that is, the wire embedding process of the motor stator winding, is a key link in motor manufacturing. This process requires delicate operation and strict quality control to ensure the performance and reliability of the motor. It is necessary to determine the appropriate wire embedding scheme based on the parameters of the motor, such as the number of poles, number of slots, and pitch. For example, for a 24-slot, 4-pole, full-pitch three-phase asynchronous motor, the wire embedding method can be summarized as "embed two, empty two, embed two, reverse two, and hang three". First, embed the lower edge (sunk edge) of the coil into the stator slot. Before entering the slot, the coil needs to be flattened and twisted to make it slightly twisted, and then carefully pulled into the slot, keeping the wires in the slot neatly parallel and non-intersecting. After the lower edge of the coil is embedded, its upper edge (floating edge) is temporarily lifted to prevent friction damage with the iron core. When lifting the edge, you can pad the insulating paper underneath it. According to the wire embedding plan, continue to embed the lower edges of other coils and lift the upper edges until the lower edges of all coils are embedded in the slot. After all the lower edges are embedded in the grooves, according to the wire embedding plan, embed the suspended upper edges into the corresponding grooves. Pay attention to keeping the coils neat and parallel.

[0003] The above methods are mostly manual operations. Although there are now large-scale automated machines that can efficiently complete the production of large quantities of motor stators in a short time, some motor manufacturers need to produce motors in small batches of multiple specifications. The automated equipment is expensive and impractical, and cannot meet the production of motor stators of multiple specifications. Summary of the invention

The hanging shuttle 30 is detachably connected with an opening assembly; one end surface of the winding block 26 is symmetrically provided with a clamping groove about the hanging groove 29, and a clamping block 32 is rotatably connected in the clamping groove. One end of the clamping block 32 is detachably connected to the coil 31, and the other end of the clamping block 32 is hinged to the clamping groove through a hinge with torsion, so that the clamping blocks 32 are arranged close to each other without being pushed by the driving block 33.

[0038] Furthermore, a side of the push ring 27 close to the silicon steel ring 11 is provided with a clearance opening for the thread hanging shuttle 30 to freely enter and exit, so as to avoid interference with the thread hanging shuttle 30.

[0039] To further optimize the solution, Figure 7 As shown, the opening and closing assembly includes a driving block 33, which is a wedge-shaped block.

The third telescopic member 35 is fixedly connected to the driving assembly; the opening and closing frame 34 is fixedly connected to the opening assembly. The expansion and contraction of the third telescopic member 35 can push the opening and closing frame 34 to expand and contract, thereby driving the driving block 33 and the pushing block 36 to expand and contract, thereby realizing the control of the opening and closing assembly and the opening assembly.

[0040] To further optimize the solution, Figure 5 As shown, the opening assembly includes a push block 36, one end of which is a wedge-shaped structure. The push block 36 passes through the winding block 26 and is slidably adapted to be equipped with a lifting block 37. A spring 38 is fixedly connected to the top surface of the lifting block 37.

The lifting hole is slidably connected to the push block 36, and the upper sliding hole is slidably connected to the spring 38, the lifting block 37, and the opening block 39 respectively.

The extension and retraction of the third telescopic member 35 can drive the driving rod 41 to extend and retract, so that the driving rod 41 drives the electric cylinder 8 and the winding block 26 to move respectively, and the winding block 26 can move relative to the push ring 27, and push the coil 31 out of the winding block 26, so that the coil 31 can be pulled into the silicon steel ring 11 by the hanging shuttle 30.

[0043] Furthermore, guide grooves are provided on the opposite sides of the support plate 7, and guide sliders are slidably connected in the guide grooves. The guide sliders are fixedly connected to the first base 2 to facilitate the up and down movement of the support plate 7.

[0044] Furthermore, by extending and retracting the first telescopic member 6 fixedly connected in the mounting groove 5, the support plate 7 and the winding unit and the driving assembly on the support plate 7 can be driven to move up and down, that is, the winding block 26 can be lifted up and down, so that the top surface and the bottom surface of the winding block 26 are respectively arranged opposite to the sliding ring 17, so as to facilitate the horizontal movement of the winding drum 15 to wind the copper wire on the winding block 26. During the copper wire winding process, the third telescopic member 35 pushes the opening and closing frame 34 to move, and the opening and closing frame 34 drives the driving block 33 and the pushing block 36 to move toward the winding block 26. The driving block 33 can slide relative to the clamping block 32, lift one end of the clamping block 32, and form a forming groove of the coil 31 between the end face of one end of the clamping block 32 and the end face of the limit ring 28.
